Inspection device and working method of inspection device for automobile tire pressure monitoring system and new energy automobile

Abstract

The invention provides an inspection device and a working of the inspection device for an automobile tire pressure monitoring system and a new energy automobile. The inspection device comprises a pressure transmitter used for tire pressure inspection, the pressure transmitter is arranged in a tire, a working signal end of the pressure transmitter is connected with a signal receiving end of a signal transmission circuit, and a signal transmitting end of the signal transmission circuit is connected with a WiFi circuit. A wireless signal sending end of the WiFi circuit is connected with a signalreceiving end of a wireless PLC, a display signal end of the wireless PLC is connected with a signal receiving end of a display, and the signal transmitting end of the WiFi circuit is connected with asignal input end of an optical coupling circuit. A working end of the optical coupling circuit is connected with a relay, the relay controls the opening and closing of an electromagnetic valve, the electromagnetic valve is arranged on an air nozzle of the tire, an acquisition signal of the pressure transmitter is obtained through the opening and closing electromagnetic valve, and the WiFi circuitis transmitted to the wireless PLC for data collection.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a detection device for an automobile tire pressure monitoring system, a working method thereof, and a new energy automobile. Background technique [0002] Tire Pressure Monitoring System (TPMS for short) has gradually become the standard configuration in the field of automotive active safety. Among highway accidents, casualties caused by tire blowouts have always been at the top of the list. Low tire pressure has become the main cause of punctures. In addition, low tire pressure will also lead to reduced tire service life and increased vehicle fuel consumption. According to the research of related companies, as far as tires are concerned, the wear rate of tires when the air pressure is too low is 2-3 times that of tires with normal tire pressure; when the tire pressure is 30% lower than the normal tire pressure, the fuel consumption will increase significantly. Whether the mo...
