Embodiment Construction

[0032] Figure 1 is a schematic structural diagram of a fuel cell vehicle controller monitoring system based on Bluetooth communication. The vehicle controller is connected with the Bluetooth wireless module through serial communication. The Bluetooth module shown is the EK-11 module produced by Finland’s Bluegiga. This module complies with the Bluetooth 2.0+EDR Class1 standard, the maximum communication rate can reach 3Mbps, and the transmission distance can reach 100 Meters, Bluetooth signals can be transmitted and received through an external antenna or a built-in antenna. The vehicle controller acts as a Bluetooth slave to establish a Bluetooth connection. The monitoring terminal is a platform device with bluetooth communication function such as a mobile phone, PDA or computer, which exchanges data with the vehicle controller through the J2ME Java platform and establishes a bluetooth connection as a host. The Bluetooth connection process needs to be paired (Pair) encryptio...

Abstract

A bluetooth communication-based controller monitoring control system for the entire fuel cell car, more particularly, the on-site real-time monitoring for the controller of the entire fuel cell car via the intelligent handset terminal end, PDA and the laptop computer. The controller monitoring control system belongs to the field of the industrial on-site supervision and is composed of a monitor terminal with the bluetooth function, a bluetooth wireless send-receive port, a entire car controller, a CAN bus set. The monitor terminal communicates with the bluetooth wireless send-receive port via the bluetooth 2.0+EDR wireless communication protocol; the bluetooth wireless send-receive port is connected with the entire car controller; the entire car controller is connected to the CAN network. The utility model has the advantages of high stability and reliability, high transmission rate, powerful anti-jamming ability and flexible application. Also, the multi-media memory cards with the large capacity such as CF, SD and MMC are adopted so as to facilitate the carry-over due to the small size.

Description

technical field [0001] The invention discloses a fuel cell vehicle vehicle controller monitoring system based on bluetooth communication, which is especially suitable for on-site real-time monitoring of fuel cell vehicle vehicle controllers by using smart phone terminals, PDAs and portable computers, and belongs to the technical field of industrial site monitoring. 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 reliability requirements, CAN bus is generally used for communication among 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...
