A system used for electric-controlled vehicle radio remote monitoring, marking and failure diagnosis

Abstract

This invention discloses one system for electrical automobile wireless remote monitor label and its fault diagnose by use of internet to realize this, wherein the device comprises automobile electrical control device, monitor label diagnose device, monitor center, wireless internet base station and internet to form communication linkage; the monitor center, sub monitor center and internet form the data transfer linkage. This invention integrates single machine, GPRS and GPS memories with large volume, communication interface module such as CAN interface, KWP interface and USB interface.

Description

technical field [0001] The invention belongs to the operation monitoring technology of electronically controlled vehicles, in particular to a device and method for performing wireless remote monitoring calibration and fault diagnosis on electronically controlled vehicles. Background technique [0002] For vehicles with electronic control or integrated electronic control devices, such as electronically controlled gasoline locomotives, electronically controlled diesel locomotives, electronically injected motorcycles, and other electronically controlled engines and powertrain vehicles, the development process of the control unit includes bench tests and road tests. Experiment in two parts. After the basic parameters and algorithms of the control unit are determined through the bench test of the electronically controlled engine, a large number of road tests are carried out on the electronically controlled vehicle to optimize the control unit to achieve the expected goal. At pre...

Problems solved by technology

Such an operation method is not only time-consuming and laborious, but also extremely inconvenient for engineers to operate.

Especially in complex road surfaces and harsh environments such as plateau, high cold, high temperature, etc., conventional laptops cannot operate normally when the test vehicle is driving

In the late stage of vehicle development, in the verification test and durability test stage of small batches of vehicles, the cost of existing data collection methods is too high, and a large amount of manpower and material resources are required for maintenance. At the same time, real-time monitoring and analysis of multiple vehicles cannot be realized.

At present, some vehicles, such as police cars, long-distance vehicles, and taxis, are equipped with communication units and vehicle driving recorders, which are used for vehicle anti-theft, driving tracking and rescue, but the functions are relatively single, and it is impossible to communicate with the vehicle control unit
