What is the main function of the controller?
The electric bikes controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric bikes. It is like the brain of the electric bikes and is an important component of the electric bikes. Electric bikes mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery vehicles, etc. Electric vehicle controllers also have different performances and characteristics due to different models.
Motor lock system: In the alert state, the controller automatically locks the motor when an alarm occurs. The controller consumes almost no power and has no special requirements for the motor. It has no impact on the normal operation of the electric bikes under battery undervoltage or other abnormal conditions.
Self-checking function: divided into dynamic self-checking and static self-checking. As long as the controller is powered on, it will automatically detect the status of related interfaces, such as handlebars, brake levers or other external switches, etc. Once a fault occurs, the control The controller automatically implements protection to fully ensure the safety . When the fault is eliminated, the protection status of the controller will automatically restore.
Reverse charging function: When braking, decelerating or coasting downhill, the energy generated by EABS is fed back to the battery to achieve a reverse charging effect, thus maintaining the battery, extending battery life and increasing mileage. Cruise function: The automatic/manual cruise function is integrated. Users can choose according to their needs. Cruise will be entered in 8 seconds and the driving speed will be stable without the need for handle control.
Controller composition
A controller usually consists of one or more microprocessors and other electronic components. Let's first look at the components of the controller:
1. Central processing unit (CPU)
The core part of the controller, similar to the human brain, is responsible for the calculation and control of the entire system. The central processing unit includes computing units, registers, control units, memories and other parts, and is the core of the controller.
2. Input/output (I/0) interface
I/O interfaces usually consist of multiple digital input/output ports and analog input/output ports. Digital input/output ports are used to input and output high- and low-level digital signals, and analog input/output ports are used to input and output analog signals. Such as voltage, current, temperature, etc.
3. Memory
The memory of the controller includes program memory and data memory. The program memory stores program codes, and the data memory is used to store important process parameters and operating data.
4. Clock
The clock part provides accurate time base and real-time clock functions to ensure the accuracy and reliability of the controller.
5. Power supply
The power supply provides stable power to the controller to ensure the normal operation of the system.
programming interface
The programming interface is the software interface of the controller, which provides engineers with an environment to write programs to master the accuracy and height of the controller system.
The above is an introduction to the basic functions of the controller and its components. Controllers play a vital role in modern industrial automation production. It can control robots, adjust motor speed, manage process, temperature, humidity and other parameters to ensure smooth, efficient and safe production process. The controller collects various parameter values in the system through sensors, analyzes and processes them, and adopts corresponding control strategies to achieve automated operation and intelligent control of the system.
