Retarder online monitoring system

Abstract

The invention belongs to the technical field of vehicle braking, and particularly relates to a retarder online monitoring system. The retarder online monitoring system comprises a CAN (Controller Area Network) bus, a data acquiring module and a retarder online monitoring device, wherein the data acquiring module is used for acquiring vehicle real-time data and a fault message; the retarder online monitoring device is communicated with the data acquiring module through a CAN bus; the retarder online monitoring device comprises a CPU (Central Processing Unit); the CPU is connected with a power supply module, a CAN receiving and transmitting module, an internal storage module and an interface module respectively; the retarder online monitoring device is connected with the CAN bus through the interface module. By adopting the retarder online monitoring system, data on any road segment and under various working conditions can be acquired, and high data reliability is achieved. Meanwhile, the field data acquiring tasks can be reduced for engineering personnel. Meanwhile, the system is simple in structure, and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking, and in particular relates to an online monitoring system for a retarder. Background technique [0002] With the development of automotive electronic technology, there are more and more electronic control products for vehicles, and the functions are also powerful. The requirements for electronic control products are also getting higher and higher. Continuously improving the performance of electronic control products has become an inevitable requirement. The data acquisition of electronic control products can provide first-hand data support for analyzing their working status and improving product performance. The development of powerful data acquisition devices has become the only choice for technical improvement and upgrading of electronic control products. At present, the general vehicle-mounted data acquisition devices require engineers to follow the vehicle to collect data on the spot. ...

Problems solved by technology

Although this method is simple and easy to implement, it has many disadvantages: 1. Only the company's internal test vehicles can be used to conduct tests on specific road sections, with a small range and less data; 2. The driver must operate in strict accordance with relevant laws during the test , the road conditions, vehicle speed, load, etc. are inconsistent with the real situation, and cannot reflect the real situation of the customer when using the retarder; 3. Many engineers are required to follow the car test, which consumes manpower and material resources, and increases R&D costs, etc.
