Download of MCC mining machine platform
the earliest appearance of the former was in 2015. In the two years from 2015 to 2017, the personnel of Vicat MLM organizations, through false propaganda, selling Vicat, holding various propaganda meetings and establishing class system, led to more than 200 countries and more than 3 million people being cheated. Although in 2017, Vicat coins have been cracked, a total of 119 backbone were arrested. However, e to the large number of people involved in Vicat, even if the backbone is captured, some offline people are still using Vicat to continue to commit fraud. In the first half of 2018, many people found signs of recovery of Vicat
top 2: mchain (M-chain or MCC)
mchain, formerly known as M-chain or MCC, appeared in the second half of 2017. Through the Ethereum blockchain, the personnel of MCC pyramid marketing organization generated token MCC for free. Through careful packaging (for example, putting token MCC online to some unknown Shanzhai exchanges, inventing Galaxy online entertainment platform and cloud mining machine), they attracted investors to invest and promised high returns to investors. After investors take the t, MCC MLM organizations will ince investors to develop offline through other means< At present, MCC has not been detected by the police and is still active. However, Yuhang Public Security Bureau and Zhejiang Economic Investigation Bureau have already issued a warning, hoping that you will not easily get on the stolen ship that has lost your property
Top 3 of MLM: radar coin (ADAR)
radar coin appeared in 2014 and was exposed as a pyramid scheme by CCTV and public security in many places. It was once known as the largest online MLM project in China, but up to now, radar coin is still active
radar coin mainly relies on the Internet and community for promotion. As few people knew the concept of mining in the early years, radar coin was introced to store or promote the concept of mining, and it has continued to this day. As early as 2016, radar coin was stripped out, formerly known as VPAL (also pyramid scheme), because the source code of radar coin and VPAL is consistent, and radar coin uses the domain name of VPAL<
Top 4 of MLM coin: LCC (light cone)
LCC is a MLM coin scam that appeared around November 2017. MLM organization staff incited investors to take the initiative to invest and develop offline by manipulating prices and drawing big cakes. In just a few months, it expanded the scope of fraud to more than 10 provinces and cities in China, resulting in 50000-80000 people being cheated, The amount involved reached 4.9 billion yuan. At present, the top management of LCC pyramid marketing organization has been arrested by the police
Top 5 of MLM coin: Xinghan chain (SGC)
Xinghan chain was launched in September 2017. Like all MLM coins, Xinghan chain often holds various conferences at home and abroad to attract members and publicize Xinghan chain. Although the people of Xinghan chain pyramid scheme deliberately designed a complex algorithm in an attempt to cover up the fact of incing investors to go offline, it is just like mmm, the world's largest Ponzi scheme, and static income sold them out
in December last year, Xinghan chain was singled out as MLM. Five days later, it was suspected of MLM by Changsha crackdown office. In April this year, it was reported as MLM by many media platforms< Top 6: electric energy chain (EEC)
there is no official website, no white paper, nor shangshanzhai exchange. The only white paper with a little technical content is completely copied. The transaction is purely by manual transfer. If you transfer 1000 yuan, you will be charged 500, and if you transfer 2000 yuan, you will be charged 1000. At first glance, I thought it was charging QQ card. Buy 1000 coins a year, only 12 coins of income, to profit completely depends on the development of offline. It was exposed in May this year that it is a pyramid scheme< Top 7: popular money (TPC)
popular money appeared around may 2017 and was exposed as MLM by Hong Kong East weekly on February 4 this year. TPC has white papers, official websites, wallets, exchanges, points websites, game applications, and formal business licenses. It has a clear division of labor and strict discipline. No one would have thought that it would be a pyramid selling coin if it did not need to pay a threshold fee of 40000 yuan for one person and get a rebate for joining the army< In late March of this year, Datang launched illegal pyramid selling in the name of blockchain all over the country, and in just 18 days, it expanded its registered members to more than 13000, involving 31 provinces, cities and autonomous regions. Xi'an police set up a special team to destroy the case after receiving the report. According to the statistics after the incident, the amount of money involved in the case exceeded 80 million yuan, and this case has become the first "blockchain" mega network pyramid selling case in China
Top 9: Hero chain (HEC)
hero chain was listed on January 13 this year. Investors hesitated and repeatedly decided to report the case when people on the platform were cheated, the currency price plummeted and the market value evaporated by 90%. On March 14, 2018, the hero chain was put on file for investigation, and the relevant person in charge disappeared immediately after putting on file
Top 10: PMD (pyramid)
PMD was launched in June 2018, which completely imitated MCC's pyramid selling routine. After careful packaging, virtual cloud miner carried out fraud and hierarchical pyramid selling. Because PMD imitates MCC too much, it was discovered by the people of MCC MLM organization and exposed
top 11: WSC
WSC appeared around February this year. There is no white paper. The so-called official website is also composed of some scattered words and pictures. The staff of the pyramid marketing organization of Wenshang chain invented the cloud miner and launched the "welfare" of sending miner after registration to attract members. After the investors took the t, the staff of the pyramid marketing organization of Wenshang chain would pull the investors to the "business school" for centralized brainwashing training and development offline
Top 12: DK appeared at the end of 2015, which completely imitated the operation mode of MMM and learned from the experience of MMM crash, changed the realization time, promised 1% income and cheated investors. If investors think that the return of static income is slow, the people of the tic money pyramid marketing organization will encourage investors to develop offline, and set up a 20 layer pyramid hierarchical system, so that the leeks that have been locked up can trick new leeks into the pit. As the operation mode of tic is constantly changing, and its behavior is relatively low-key, so TIC has not been able to attract the attention of relevant departments and is still active
it's very tiring to move bricks. Please accept if you are satisfied!
I haven't heard of this kind of virtual currency. The registration method of virtual currency is the same
we can learn from the registration methods of bitcoin, Ruitai coin and Laite coin, but we need to be careful about the investment of these digital currencies
MCC generally refers to microcrystalline cellulose (MCC), which is a kind of free flowing short rod or powdery porous particles that can be hydrolyzed by dilute acid to limit degree of polymerization (loop). The color of MCC is white or nearly white, odorless and tasteless. The particle size is generally 20 ~ 80 LM, and the limit degree of polymerization (LODP) is 15 ~ 375; It is non fibrous and highly mobile. It is insoluble in water, dilute acid, organic solvent and oil. It is partially dissolved and swelled in dilute alkali solution. It has high reaction performance in carboxymethylation, acetylation and esterification. Microcrystalline cellulose is widely used in medicine, food, cosmetics and light chemical instry e to its low degree of polymerization and large specific surface area
extended data :
virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent's Q currency, Q point, Shanda's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.)
chivalrous Yuanbao (used for chivalrous road game), silver (used for bixue Qingtian game), and the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency
At present, there are more than 100 kinds of digital currency in the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"network virtual currency can be roughly divided into three types
the first type is the familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency
the investigation conclusions of public security organs are the most authoritative.

3. Transportation company:
MCC shipping company is the entity company of Asia branch line of A.P. Mueller Maersk shipping group, and its full name is MCC transportation Singapore Co., Ltd. MCC transportation Singapore company was purchased from EAC by Maersk shipping group in May 1993. It was renamed mercantile cargo consolidators (MCC). Maersk shipping group will hand over all its routes around Asia to MCC transportation Singapore Co., Ltd. in 2009, so as to avoid overlapping ports and improve operational efficiency
4. Mobile Country Code:
mobile country code, the resources of MCC are uniformly allocated and managed by ITU, which uniquely identifies the country of the mobile user, with 3 digits in total, and 460 in China< 5. China Metallurgical Group:
MCC, China Metallurgical Science and Instry Group Co., Ltd. (MCC for short in Chinese, MCC for short in English), is a super large enterprise group supervised by the state owned assets supervision and Administration Commission of the State Council. It is a pioneer and builder of China's metallurgical instry, and has successively undertaken the construction tasks of Baosteel, Angang, WISCO, Pangang and other major national iron and steel instrial bases, It has made outstanding contributions to the development of China's metallurgical instry
6. Online community:
is a website for the exchange of Chinese teenagers and Chaozhou people. MCC is a gathering place for all kinds of beauties, geeks, trendsetters and interesting people
7. UnionPay MCC:
the category code of special merchants who swipe bank cards in China is set by China UnionPay, and each POS merchant expands the common classification code used by banks< Motor control center:
also known as motor control center, motor control center, or MCC. The motor control center manages the power distribution and instruments and equipment in a unified way. All kinds of motor control units, feeder connector units, distribution transformers, lighting distribution boards, interlocking relays and metering equipment are installed in an integral enclosure and powered by a common enclosed bus
MCC Code:
MCC code is also called merchant category code. It is set by the acquiring institution for the signing merchant, which is used to indicate the UnionPay card transaction environment, the main business scope and instry ownership of the merchant, which is the main basis for judging the settlement fee standard of domestic inter-bank transaction merchant; It is also one of the important basic data to carry out the analysis and report of UnionPay card transaction instry and risk management and control of UnionPay card business
merchant setting:
when an acquiring institution signs a special merchant, it should investigate and understand the merchant's actual main business, business scope and business status, so as to ensure the merchant's good business reputation and stable financial status
merchant code format (merchant number format), according to the bank card acquiring management measures, the merchant number is 15 digits: institution code (3 digits) + region code (4 digits) + merchant type (4 digits) + merchant sequence number (4 digits) Please refer to the detailed comparison table of MCC and meaning of Beijing UnionPay)
the merchant category code set by the acquiring institution for the special merchant must be consistent with the main business of the merchant
1. The main business of a merchant refers to the business type that contributes the most to the daily business income of the merchant
2. When the merchant's business license is described by enumeration, the first item of business scope can be ranked as the merchant's main business; When the business license of the merchant does not specify the specific business scope, the acquiring institution has the responsibility to determine the main business of the merchant in the merchant credit investigation
3. When the main business or business scope of the merchant changes, the acquirer shall re code the merchant in time
4. If the business license lists a variety of business scope, and the acquirer selects the business item with the lowest dection rate as the category code for the merchant, the acquirer should be able to prove that the business item is the main business of the merchant.
■ MCC: motor control center, security MCC is a part of MCC system. Provide control of power driven equipment
■ UPS: AC (DC) uninterrupted power supply system, which is used to prevent power failure. It is mainly composed of inverter controller and storage battery
DCS: commonly used control procts are divided into DCS and PLC. The concept of DCS is extended to FCS
■ DCS, distributed control system, also known as distributed control system
DCS is worth knowing in detail, which represents the mainstream of control system technology:
■ what is the difference between DCs and PLC< In terms of development,
DCS is developed from the traditional instrument panel monitoring system. Therefore, DCS congenitally focuses on instrument control. For example, the Yokogawa CS3000 DCS system we use does not even have the limitation of PID number (PID, proportional differential integral algorithm, is the standard algorithm for closed-loop control of regulating valve and frequency converter. Generally, the number of PID determines the number of regulating valves that can be used)
PLC is developed from the traditional relay circuit, the original PLC does not even have the ability to process analog quantity, so PLC emphasizes the logic operation ability from the beginning
2. In terms of system scalability and compatibility:
there are many control procts in the market, no matter DCS or PLC, there are many manufacturers in the proction and sales. For the PLC system, there is generally no or little need for expansion, because the PLC system is generally used for equipment. Generally speaking, PLC has few compatibility requirements. For example, two or more systems require resource sharing, which is also very difficult for PLC. And PLC generally uses a special network structure, such as Siemens MPI total linear network, even adding an operator station is not easy or the cost is very high
in the process of development, DCS is also a system of its own, but most of the DCS systems, such as Yokogawa, Honeywell, abb and so on, although the communication protocols within the system (process level) are not the same, but the operation level network platform chooses the Ethernet network and adopts the standard or modified TCP / IP protocol. This provides easy scalability. In this kind of network, the controller and computer exist as a node. As long as the network reaches the place, it can increase or decrease the number of nodes and arrange the location of nodes at will. In addition, based on OPC, DDE and other open protocols of windows system, each system can also communicate easily to realize resource sharing< In terms of database,
DCS generally provides a unified database. In other words, once a data exists in the database in the DCS system, it can be referenced in any case, such as in the configuration software, in the monitoring software, in the trend chart, in the report... But the database of the PLC system is usually not unified, and the configuration software, the monitoring software and even the filing software have their own database. Why is it often said that Siemens S7 400 is called DCS only when it is above 414? Because SIEMENS PCS7 System only uses a unified database, and PCS7 requires the controller to be at least S7 414-3 or above
4. From the aspect of time scheling:
PLC programs generally can not run according to the preset cycle. PLC program is executed from beginning to end and then from the beginning Now some new PLC has been improved, but the number of task cycle is limited. DCs can set the task cycle. For example, fast tasks. It's also the sampling of sensors. The change time of pressure sensor is very short, so we can use 200ms task cycle to sample, while the lag time of temperature sensor is very large, so we can use 2S task cycle to sample. In this way, DCs can reasonably schele the resources of the controller
5. From the perspective of network structure:
generally speaking, DCS usually uses two-layer network structure, one layer is process level network, and most DCS use their own bus protocols, such as MODBUS of Yokogawa, PROFIBUS of Siemens and abb, can bus of ABB, etc. these protocols are based on the standard serial port transmission protocol RS232 or RS485. The field IO mole, especially the analog sampling data (machine code, 213 / scan cycle) is very large, and there are many interference factors in the field, so the network standard with large data throughput and strong anti-interference ability should be adopted. The bus structure based on RS485 serial port asynchronous communication mode meets the requirements of field communication
the sampling data of IO is converted into shaping data or real data by CPU and transmitted on the operation level network (layer 2 network). Therefore, the operation level network can adopt the network standard of moderate data throughput, fast transmission speed and convenient connection. At the same time, because the operation level network is generally arranged in the control room, the requirement of anti-interference is relatively low. So standard Ethernet is the best choice. TCP / IP protocol is a standard Ethernet protocol, generally we use 100mbit / s communication speed
the task of PLC system is relatively simple, so the amount of data to be transmitted is generally not too large, so the common PLC system is a layer of network structure. Process level network and operation level network are either combined together, or process level network is simplified as internal connection between moles. Ethernet is not or rarely used by PLC
6. From the scale of application objects:
PLC is generally used in small automatic control places, such as equipment control or a small amount of analog control and interlocking, while large-scale applications are generally DCS. Of course, this concept is not very accurate, but it is very intuitive. Traditionally, we call a system larger than 600 points DCS, and a system smaller than 600 points PLC. Our heat pump and QCs, horizontal procts supporting the control system is generally called PLC
> we have talked about so many differences between PLC and DCS, but we should realize that PLC and DCS are actually moving closer to each other today. Strictly speaking, PLC and DCs can't be separated at the same time, and the concept between them has been blurred many times. Now, let's talk about the similarities
1. In terms of function:
PLC has the control function of analog quantity, and some PLC systems even have strong analog quantity processing ability, such as Yokogawa fa-ma3, Siemens S7 400, ABB Control Logix and Schneider quantum system. DCs also has quite strong logic processing capability. For example, we have realized all possible process interlocking and equipment linkage start and stop on CS3000< In terms of system structure,
PLC and DCs have the same basic structure. With the development of PLC, it has been transplanted to the computer system control, and the traditional programmer has been eliminated. Small application of PLC generally use touch screen, large-scale application of PLC comprehensive use of computer system. Like DCS, controller and IO station use fieldbus (generally based on RS485 or RS232 asynchronous serial communication protocol). If there is no expansion requirement between controller and computer, that is to say, only one computer is used, this bus will also be used for communication. But if more than one computer is used, the system structure will be the same as DCS, and the upper computer platform will use Ethernet structure. This is one of the reasons for the fuzzy concept of PLC and DCS
3. The development direction of PLC and DCS:
the miniaturized PLC will develop to a more professional point of view, such as more targeted functions, more targeted application environment, etc. The boundary between PLC and DCS is graally weakened until it is completely integrated
DCS will continue to develop in the direction of FCS. The core of FCS is not only the control system is more decentralized, but also the instrumentation. The application of FCS in foreign countries has developed to instrument level. The control system only needs to deal with signal acquisition and provide human-machine interface and logic control. The control of the whole analog quantity is distributed to the field instrument. There is no need for traditional cable connection between the instrument and the control system, and the field bus is used to connect the whole instrument system At present, Yokogawa has used FCS in CNOOC and Shell Petrochemical Project in China, and intelligent instruments are used in instrument level, such as ejx, which has the most advanced control level in the world)< How to treat PLC and DCS correctly
personally, I never emphasize the advantages or disadvantages between PLC and DCS. I use a new term "control procts" for them. We provide users with the most suitable control system. Most users will not use DCS because they want to use a set of DCS. Control procts must be positioned on the basis of meeting the process requirements of users. In fact, the users who use DCS or PLC have never touched automatic control procts or have some special needs. Overemphasizing this will only lead to verbal disputes
from the differences and similarities between PLC and DCS, we know the general situation of control procts. Note that as professionals, we should not define PLC or DCS for our procts, and we should not treat our procts in this way psychologically.
