Abstract

The invention relates to an automobile tire state monitor, which consists of a pressure sensor, a temperature sensor, a battery, a signal processing unit, a wireless transmitter, a wireless receiver and a display, wherein the pressure sensor and the temperature sensor are connected with the signal processing unit through wires; the battery is connected with the signal processing unit which is connected with the wireless transmitter; a communication link is arranged between the wireless transmitter and the wireless receiver which is connected with the display; the battery is connected with a charging circuit which is connected with an induction coil; the outside of the induction coil is at least provided with a magnet; and a space is arranged between the magnet and the induction coil. The induction coil and the charging circuit are arranged inside a tire, a magnetic field is arranged on an automobile suspension outside the tire, and the battery is charged by the current generated by the induction coil, so that the automobile tire state monitor can greatly prolong the working period of the battery and avoid regular disassembly of the tire.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to signal detection and control, in particular to an automobile tire state monitor. Background technique: [0002] The condition of car tires is closely related to the performance and safety of the car. Air pressure and temperature are the main factors affecting tire operation. Typically, tire pressure and temperature are measured while the vehicle is parked. However, the real-time situation of the tire pressure and temperature of the car during driving is more important for safety. In the prior art, a pressure sensor, a temperature sensor and a battery are arranged in the tire, and an RF wireless transmitter is used to transmit a signal to a display installed in the vehicle compartment. Due to the limited capacity of the battery, in order to ensure the normal operation of the sensor and the normal transmission of wireless signals, the tire needs to be disassembled to replace the battery,...
