Online testing system for thermal management system

Abstract

The invention discloses an online testing system for a thermal management system. The online testing system comprises a PLC, an industrial computer, a CN communication module, a small relay set, a controller set, a frequency conversion module, a testing pipeline, a testing circulating pump, a sensor module set, a flow meter and a pneumatic valve which are all integrated in a control cabinet, wherein a circulating water tank is arranged outside the control cabinet, an electric heating rod and a sewage pump are arranged on the circulating water tank, the electric heating rod is connected with the small relay set through the controller set, and the sewage pump is connected with the small relay set through the controller set; the PLC is connected with the industrial computer, the industrial computer is connected with the CN communication module, and the CN communication module is used for collecting temperature, speed and flow data information of the thermal management system and transmitting the collected data information to the industrial computer. According to the invention, a plurality of data parameters of the thermal management system can be tested, and the installation and detection are convenient.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to an online testing system for a thermal management system. Background technique [0002] At present, only a simple test can be performed on the vehicle thermal management system: [0003] 1. Detect whether there is leakage of the product and whether the installation accessories are loose; [0004] 2. When power-on detection, there are many wirings, and various water pipes and testing instruments are equipped on site, which is cumbersome to use; [0005] 3. All the testing data need to be recorded on site. After the testing is over, more disassembly and assembly operations are required, and the operation efficiency is low. Contents of the invention [0006] The purpose of the present invention is to provide an online testing system for a thermal management system. [0007] To achieve the above object, the present invention adopts the following content: [0008] Ther...
