Data recording system of vehicle mounted fuel cell engine

Abstract

A kind of truck fuel battery engine's date record system, it is composed of singlechip and its periphery circuit, the singlechip and the fuel battery stack simple link pressure measure cell change the data in real time, the singlechip has clock chip and its periphery circuit, CAN communication interface, communication interface and SD card (502), the clock chip does data communication through the singlechip's SPI interface; SD card and the singlechip process the pressure change of the communication information through communication interface circuit, record each process work state of the storage fuel battery engine system, CAN interface process that the singlechip changes the date in real time with each control point and the communication with the outer monitor computer. The system can manage each single link battery pressure as the gateway, optimizes the distribution of the engine's control system, has the merits that the storage speed is fast, read is convenience, the cost is low, the data memory is safe, it can satisfy the truck condition request, the clock can run normally when the system has no electricity.

Description

technical field [0001] The invention belongs to a vehicle-mounted fuel cell engine control system, in particular to a data recording system for optimizing the fuel cell engine control system. Background technique [0002] The battery stack of a vehicle-mounted fuel cell engine is composed of hundreds of single-cell fuel cells in series, usually including a hydrogen supply system, a cooling system, and an air supply system. The amount of data that needs to be monitored and controlled is large, so each control node of the fuel cell engine control system The reasonable layout and real-time recording of the working status can improve the data exchange capability of each component of the fuel cell engine in the vehicle environment and help the fuel cell engine system analysis and failure analysis. The traditional method is to separate the fuel cell engine control system and the system working state monitoring record. The method often used in data recording is: 1) Use a mobile com...

AI Technical Summary

Problems solved by technology

[0004] 1) In the vehicle environment, using a mobile computer to monitor and record the working status of the fuel cell engine system requires manual operation, and each vehicle must be equipped with a computer, which is costly;

[0005] 2) Use wireless transmission to monitor and record the running status of the engine. The wireless data transmission module has poor anti-interference ability, slow transmission speed, and is limited by the transmission distance. Although the GPRS method can overcome the above shortcomings, the cost is very high;

[0006] 3) Use a mobile hard disk or CF card to design a special monitoring system and put it on the vehicle, which not only takes up system space, but also requires additional costs
