Bluetooth intelligent mobile terminal-based hydrodynamic retarder monitoring system

Abstract

The invention discloses a Bluetooth intelligent mobile terminal-based hydrodynamic retarder monitoring system, which comprises a hydrodynamic retarder, a lower computer and an upper computer, wherein an oil temperature sensor, a water temperature sensor, a pressure sensor and a hand-operated / foot-operated gear switch are arranged on the hydrodynamic retarder, and are connected with the lower computer; the lower computer is connected with an automotive CAN (controller area network) bus; a first Bluetooth module is arranged on the upper computer; a second Bluetooth module is arranged on the lower computer; the upper and lower computers communicate through the first and second Bluetooth modules. The system is used for monitoring the statuses of a vehicle and the retarder on line in real time by monitoring data produced by a hydrodynamic retarder controller product in real time, and in addition, multiple functions of real-time data acquisition and display, online debugging, failure diagnosis and the like can be realized; the monitoring system has multiple advantages of low cost, convenience, high speed, high reliability, reduction in requirements on technicians and the like, and meanwhile, the comprehensive application of a mobile terminal and automotive electronics is guided.

Description

【Technical field】 [0001] The invention relates to the technical field of hydraulic retarders, in particular to a hydraulic retarder monitoring system. 【Background technique】 [0002] In the existing hydraulic retarder monitoring system, the acquisition and monitoring of test data mainly use CAN acquisition tools to collect the data on the retarder controller and the CAN bus of the vehicle and connect them to the computer. Although this method is simple and easy to implement, there are many disadvantages: 1. Often when the engineering personnel follow the vehicle test, the engineering personnel must remove the vehicle wiring panel, disassemble the vehicle wiring with the retarder installed, and disassemble the self-made 16 Only when the CAN bus connector of the vehicle is led out by the needle adapter wire can online monitoring be carried out, which increases the number of fault points; Not very convenient; 3. An inverter must be connected to the car to charge the handheld c...

Although this method is simple and easy to implement, there are many disadvantages: 1. Often when engineering personnel follow the vehicle for testing, the engineering personnel must remove the vehicle wiring panel, disassemble the vehicle wiring with the retarder installed, and disassemble the self-made 16 Only when the CAN bus connector of the vehicle is led out by the needle transfer wire can online monitoring be carried out to increase the fault points; Not very convenient; 3. An inverter must be connected to the car to charge the handheld computer, and the power consumption of the handheld computer is relatively large
