3ASC25H705-7  控制器模块  可以采集输入信号

3ASC25H705-7  控制器模块是一个复杂的系统，主要由CPU模块、输入模块、输出模块和编程器组成。

CPU模块是控制器模块的大脑和心脏，由微处理器（CPU芯片）和存储器组成。它不断地采集输入信号，执行用户程序，刷新系统的输出。存储器则用来储存程序和数据。

3ASC25H705-7 输入模块和输出模块简称为I/O模块，它们是系统的眼、耳、手、脚，是联系外部现场和CPU模块的桥梁。输入模块接收和采集输入信号，这些信号有两类：一类是从按钮、选择开关、数字拔码开关、限位开关、接近开关、光电开关、压力继电器等开关量输入信号；另一类是由电位器、热电偶、测速发电机、各种变送器提供的连续变化的模拟量输入/输出信号。

此外，3ASC25H705-7 还有很多具体的控制器模块，如车身控制单元（BCM）、EPS电子助力转向系统、方向盘转角传感器（SAS）等。车身控制单元主要实现车身门控制包括门锁、各种灯光、前后洗涤、前后雨刮、电动车窗等控制。EPS是提供辅助转向动力的系统。方向盘转角传感器用于检测车辆行驶过程中方向盘的转角和转速，为车辆的其他控制系统如ESC、EPS、AFS等提供信号。

3ASC25H705-7 Controller module is a complex system, mainly composed of CPU module, input module, output module and programmer.

The CPU module is the brain and heart of the controller module and consists of a microprocessor (CPU chip) and memory. It constantly collects input signals, executes user programs, and refreshes the output of the system. Memory is used to store programs and data.

3ASC25H705-7 Input module and output module referred to as I/O module, they are the eyes, ears, hands, feet of the system, is the bridge to contact the external field and CPU module. The input module receives and collects the input signals, which have two types: one is from the button, select switch, digital code switch, limit switch, proximity switch, photoelectric switch, pressure relay and other switch input signals; The other type is the continuously varying analog input/output signal provided by potentiometers, thermocouples, tonometric generators, and various transmitters.

In addition, 3ASC25H705-7 also has many specific controller modules, such as body control unit (BCM), EPS electronic power steering system, steering wheel Angle sensor (SAS) and so on. The body control unit mainly realizes the control of the body door, including the lock, various lights, front and rear washing, front and rear wiper, electric window and so on. EPS is a system that provides auxiliary steering power. The steering wheel Angle sensor is used to detect the steering wheel Angle and speed during the driving process, and provide signals for other vehicle control systems such as ESC, EPS, AFS, etc.
