Abstract

The invention discloses a temperature alarm system of an eddy current retarder based on voltage-constant driving. The system is characterized by being composed of a signal input circuit, an automobile power supply, a voltage-constant driving circuit, a trigger circuit, a display circuit and an alarm circuit, wherein the voltage-constant driving circuit is connected with the signal input circuit and the automobile power supply, the trigger circuit and the display circuit are connected with the voltage-constant driving circuit, and the alarm circuit is connected with the display circuit. The working temperature of the eddy current retarder is monitored in real time and displayed visually via screen, so that a driver can know the working temperature of the eddy current retarder at any time; and the system includes constant driving voltage, so that the system is driven linearly, and the stability of the system is improved.

Description

technical field [0001] The invention relates to a temperature alarm system for an eddy current retarder, in particular to a temperature alarm system for an eddy current retarder based on constant voltage drive. Background technique [0002] With the wide application of eddy current retarders in my country's automobile industry, the safety of its use has been paid more and more attention by automobile manufacturers and users. When the eddy current retarder is working, the temperature of the rotor and coil rises rapidly, and the installation position of the eddy current retarder is very close to the oil seal end cover, which can easily cause the fuel tank to catch fire, and then cause a vehicle fire accident, resulting in serious accidents. loss. In order to avoid accidents caused by excessive temperature of the eddy current retarder, it is necessary to design a temperature alarm device to detect the temperature of the main engine of the eddy current retarder. When the temper...
