[0003] Indirect TPMS (abbreviation: WSB TPMS): This system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between the tires to achieve the purpose of monitoring the tire pressure. The condition of the air pressure and the speed exceeding 100 km / h are judged, the system calibration is complicated, the location of the faulty tire is not accurate enough, and the air pressure value cannot be reflected intuitively and accurately
[0004] The other is Pressure-Sensor Based TPMS (abbreviation: PSB TPMS, or direct TPMS). This system uses the pressure sensor installed in each tire to directly measure the air pressure of the tire, and the air pressure of each tire is measured. Display and monitoring, when the tire pressure is too low or there is leakage, the system will automatically alarm; the main disadvantage: the battery has a life requirement, which can only reach 8 years at most

The invention discloses a device for monitoring pressure temperature of a battery-free tire. The pressure temperatures of multiple tires are simultaneously monitored. The device comprises a processor, a collector, a receiving / transmitting antenna, a display and a SAW sensor arranged on the tire, wherein the processor is connected with the collector and the display respectively; the collector is connected with the receiving / transmitting antenna; the receiving / transmitting antenna is connected with the SAW sensor through electromagnetic waves. According to the device for monitoring pressure temperature of the battery-free tire, the processor, the collector, the receiving / transmitting antenna, the display and the SAW sensor which is arranged on the tire are matched, so that the pressure temperatures of the multiple tires are simultaneously monitored, a battery is not needed, the device is convenient to use, and the environment is not polluted.
Description
technical field [0001] The invention relates to tire monitoring equipment, in particular to a battery-free tire pressure and temperature monitoring device mainly used for monitoring the pressure and temperature of automobile tires. Background technique [0002] At present, there are two ways to detect tire pressure: [0003] Indirect TPMS (abbreviation: WSB TPMS): This system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between the tires to achieve the purpose of monitoring the tire pressure. The condition of the air pressure and the speed exceeding 100 km / h are judged, the system calibration is complicated, the location of the faulty tire is not accurate enough, and the air pressure value cannot be reflected intuitively and accurately. [0004] The other is Pressure-Sensor Based TPMS (abbreviation: PSB TPMS, or direct TPMS). This system uses the pressure sensor installed in each tire to directly measure the air pressure of the ti...
