Abstract

Disclosed in the invention is an eddy current retarder temperature alarm system based on a grid coupling amplification circuit. The system is characterized in that the system is composed of a signal input circuit, a power supply circuit, a trigger circuit, a display circuit, a grid coupling amplification circuit, and an alarm circuit. The power supply circuit is connected with the signal input circuit; the trigger circuit, the display circuit, and the grid coupling amplification circuit are connected with the power supply circuit; and the alarm circuit is connected with the display circuit. The grid coupling amplification circuit is also connected with the trigger circuit connected with the display circuit. According to the invention, with the grid coupling amplification circuit, a temperature signal inputted into the trigger circuit can be amplified, so that the trigger circuit can control the alarm circuit well. Once the working temperature of the eddy current retarder is a little high, an alarm signal can be sent out timely.

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 a grid coupling amplifier circuit. 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...
