远程告警通信系统架构

can总线报警通信网络是以can总线为传输接口,利用各种传感器和执行器作为外部物理量的输出和输入,并利用具有can功能的单片机PIC18F458制作节点模块的分布式监控系统。单片机上的模拟/数字(A/D)转换器对传感器的传感值进行转换,然后将数据发送到CAN总线,最后主控系统在接收到数据后进行计算和逻辑判断,最后将结果显示在LCD面板上。此外,主控室还可以通过设置和比较默认值来控制节点模块上的设备,或使用开关按钮发送制动和关闭制动的信息,从而达到自动监控的目的。

Can bus alarm communication network takes CAN bus as the transmission interface,USES various sensors and actuators as the output and input of external physical quantity,and USES PIC18F458,a single chip microcomputer with THE function of CAN,to make the distributed monitoring system of node module.The analog/digital(A/D)converter on the MCU converts the sensor's sensing value,and then sends the data to CAN bus.Finally,the master control system performs calculation and logical judgment after receiving the data,and finally displays the results on the LCD panel.In addition,the main control room can also control the equipment on the node module by setting and comparing default values,or use the switch button to send braking and braking off information,so as to achieve the purpose of automatic monitoring.
