Abstract

The invention discloses a signal conditioning circuit-based efficient eddy current power-measuring system. The system is composed of a console, a signal control unit, a to-be-measured motor controller and an eddy current loader which are connected with the signal control unit, a to-be-measured motor which is connected with the to-be-measured motor controller, a signal collector which is connected with the to-be-measured motor, a signal conversion unit which is connected with the signal collector, a power analyzer which is connected with the signal conversion unit, a thermostatic controller which is connected with the eddy current loader, and a display which is connected with the console, wherein the power analyzer which is also connected with the console, and the to-be-measured motor is also connected with the eddy current loader. The system is characterized in that the console is connected with the signal control unit through the signal conditioning circuit. According to the system of the invention, the signal conditioning circuit is adopted, and therefore, various modes of the to-be-measured motor and the eddy current loader can be switched fast, and control precision is high, and the test efficiency of the system of the invention can be effectively improved.

Description

technical field [0001] The invention relates to a detection system, in particular to a high-efficiency eddy current dynamometer system based on a signal conditioning circuit. Background technique [0002] At present, the main means of testing the electric performance of electric vehicles is to use the equipment for testing traditional internal combustion engines to complete loading tests, use testing equipment such as voltmeters and ammeters to perform data detection of electrical parameters, and then process and analyze data after the detection is completed. However, there is a big difference between the test of the electric system and the test of the traditional engine. The traditional internal combustion engine mainly detects the characteristics of the motor's speed and torque, and its corresponding parameters such as power factor, line voltage, line current, and active power cannot be directly calculated. Moreover, the real-time performance of detection equipment such as...
