Communication analysis of body control system Automobile bus simulation development tool Chengdu Panfeng Technology
Analysis of communication requirements of body control system Before designing the communication protocol of bus automobile body control system, first analyze its communication requirements. Communication, that is, information exchange, is ubiquitous in the automobile bus body control system and runs through the entire process of the master/slave module products from leaving the factory to loading and then working.
Before the master/slave module product leaves the factory, the product information storage area is empty. This product has no identity and does not have any functions. It is necessary to first produce the product serial number in the host computer configuration software and then download the serial number information together with the manufacturer, product version number, factory time and other product information to the module through the computer.
Before loading the master/slave module product, the master module needs to first make sure that it has downloaded product information, otherwise the master module will not work properly. According to the design scheme of the proposed body control system, the main station module is the communication management and control core of the system and stores the configuration information of the entire body control system. The system configuration information includes the composition of the body system and the functions of each pin, which is composed of the following types of information:
System overview information:
The number of slave modules included in the body control system and the address of each slave node , Model name and model configuration time
, Pin configuration information:
The pin configuration information of each slave module in the body control system includes the pin configuration information of each slave module in the system, such as pin type , the corresponding message, input/output control method, analog threshold, pulse frequency and duty cycle and other information also include the reference value list information of the analog input pin
, control logic information:
That is, the control mode of each output pin of the slave module is that one control logic corresponds to one output pin.
