What blockchain is bas
[answer analysis] building automation system (BAS) refers to the automatic control function of the building itself, including the automatic process of perception, judgment, decision-making, response and execution. It is mainly composed of four parts: environmental equipment monitoring system, energy equipment monitoring system, fire protection system and security monitoring system.
1. The English full name of bas is brake assist system, which means brake assist system in Chinese. It can detect the situation encountered in driving from the speed of the driver stepping on the brake pedal. When the driver quickly steps on the brake pedal in an emergency, but the stepping force is insufficient, the system will increase the braking force to the maximum in less than 1 second, and shorten the braking distance in emergency braking
EBD is called electronic brake force distribution in English, which means electronic brake force distribution in Chinese. The function of EBD is to calculate the friction value of four tyres e to different attachment at the moment of vehicle braking, then adjust the brake device to adjust the speed according to the set procere in order to match the braking force and friction force to ensure the vehicle's stability and safety. p> EBA is called electronic brake assist in English, which means electronic brake assist in Chinese. EBA is an advanced automotive electronic proct, which is composed of sensors, actuators and controllers. The core actuator is the electronic vacuum booster in the car. Its working principle is to install a pressure sensor on the main brake pump, through which the driver can sense whether the driver has emergency braking behaviorin case of emergency braking, the on-board control computer will start the electromagnetic mechanism inside the electronic vacuum booster and increase the braking pressure to the maximum servo point of the booster. The response time of the double diaphragm electronic booster is 0.4 seconds to reach the maximum servo pressure of the booster. The essence of EBA is to realize the brake by wire function of vehicle. When EBA is combined with long-range radar, lidar or other vision systems, it can realize the functions of adaptive cruise system and active collision avoidance
extended data
since a large number of high-tech procts have been applied to the field of automobile manufacturing, the relevant indicators of automobile have indeed become more advanced, and the key technical indicators such as handling and safety have been greatly improved. But everyone should know one thing clearly: so far, a lot of cars still need people to control! The ability of the driver is always the first element of vehicle control. But at present, there are many common sense problems that are not known by everyone, such as braking
braking is a very important skill in vehicle control technology. In recent years, e to the popularity of a large number of electronic control components, a lot of work in braking technology is participated or even taken over by computers. Even so, there are a lot of new knowledge about braking that all drivers should always remember, because no matter how powerful the electronic control device is, what a high-tech car will become a killing machine if it doesn't have the chance to give full play or even work
in fact, all the electronic control equipment on the car has limitations. Each system only plays its control ability according to specific conditions, and the vehicle is ultimately controlled by the driver. Don't rely too much on these high-tech equipment, because these devices are not intelligent or omnipotent. It must be remembered that the only purpose of all electronic auxiliary control devices is to provide you with more opportunities to save yourself and avoid danger in a critical situation. Your life is only in your own hands
OLT. The data forwarding mode is the same as that of switch. However, compared with switch, OLT has some different functions. For example, OLT can automatically discover ONU and send network management address to ONU
ABS is an anti lock braking system, which can be installed on any vehicle with hydraulic brake. It uses a rubber air bag in the valve body to give the brake oil pressure to fill the ABS valve body when the brake is pressed. At this time, the air bag uses the middle air barrier to return the pressure, so that the wheel can avoid the lock point
to put it simply, bas is similar to a brake assist, which prevents too light pedaling from having no effect; ABS is similar to a buffer to the brake to prevent the wheel from locking up when you step too heavily. If the front wheel is locked up, it is easy to have the situation that you can't control the driving direction of the vehicle. If the rear wheel is locked up, it is very easy to have sideslip.
the actuator is used to change the controlled quantity, for example, the motor as the actuator can change the angle of the manipulator
the measuring element is used to measure the controlled quantity, for example, the rotation angle of the manipulator can be detected by using resolver or encoder
control elements are used to achieve closed-loop control and improve the performance of the controlled system. They are generally implemented by analog circuit, DSP, PLC or computer. They can correct the controlled object and change the open-loop transfer function of the system, so that the closed-loop system can meet certain performance requirements.

Fas: automatic fire alarm system
Brake assist system (BAS) provides necessary support for effective braking. By continuously comparing the speed of pressing the brake pedal, the system will recognize the emergency braking situation. If the driver is frightened and the speed when pressing the brake pedal is faster than the normal value stored in the control unit, the brake assist system will automatically work to establish the maximum brake pressure and make the brake deceleration rise to the maximum value quickly
