Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] figure 1 Shown is a schematic structural diagram of the fuel cell vehicle controller monitoring system. The upper computer is a notebook computer with a PCMCIA port, which is connected with the vehicle controller and the vehicle CAN network through a PCMCIA CAN card, and the CAN card type can be ICPCM-CO. The main chip of the controller is preferably MC68376 single-chip microcomputer, which has one CAN and is directly connected to the CAN bus. The monitoring system receives and sends data from the host computer respectively. The received data is completed by the interrupt service sub-function. The sending buffer sends control parameters to the CAN bus in each control cycle. The priority level setting of the two CAN data frame IDs should be higher than that of fuel cell vehicles. The priority level of all other component nodes in ...

Abstract

A monitor system of a whole car controller for CAN bus fuel battery vehicles includes three parts: an upper bit set, CAN card and its bus and a lower bit set, in which, the PCMCIM interface of the upper bit set is connected with CAN interface of the lower bit set via the CAN card and CAN bus, the upper bit set sends request words and control parameter address to calibrate the parameters of the controller on line, the lower bit set whole car controller realizes on-line program of CAN bus communication by imaging the executing code, realizing site monitor and management for high rate of data transmission by CAN bus technology and Matlab software platform.

Description

technical field [0001] A CAN bus-based fuel cell vehicle controller monitoring system relates to the field of industrial site monitoring technology, and is especially suitable for real-time monitoring and monitoring of fuel cell vehicle controllers with high data transmission rates using mobile terminals such as notebook computers. manage. Background technique [0002] Fuel cell vehicles adopt a distributed control system structure, each component has an independent controller, and the vehicle controller performs energy management on the entire system and coordinates control of each component. In order to meet the characteristics of large amount of system data exchange, high real-time performance and high reliability, the CAN bus is used for communication between the controllers of the entire distributed control system. [0003] In the process of debugging and matching calibration of the control algorithm of the vehicle controller, it is necessary to monitor the working sta...
