Tire pressure monitoring device with a dynamic energy-saving mechanism and energy-saving method of tire pressure monitoring

A tire pressure monitoring device with a dynamic energy-saving mechanism, installed on a car, the tire pressure detector comprising:

• a plurality of tire pressure detectors, mounted on a plurality of car tires;
• wherein each tire pressure detector includes a regulating unit and a detecting unit;
• wherein the detecting unit detects tire pressure and temperature of the corresponding tire and generates a first signal, the first signal is transmitted through a first transceiver unit of each of the tire pressure detector;
• wherein the regulating unit adjusts and changes a signal strength, receiving sensitivity or data update times of the first transceiver unit;
• and
• a main control receiver, mounted in the car and duplex wirelessly connected with every tire pressure detector;
• wherein the main control receiver includes a second transceiver unit;
• wherein after the first signal of each of the tire pressure detectors is transmitted to the second transceiver unit, the second transceiver unit generates and transmits a feedback information back to the first transceiver unit, after receiving the feedback information, each of the tire pressure detectors activates the regulating unit, and the regulating unit adjusts and changes the signal strength, receiving sensitivity or data update times of the first transceiver unit according to the feedback information;
• through the repeated signal transmission between each of the tire pressure detectors and the main control receiver, the signal transmission range of each tire pressure detector in the transmission of the first signal can be matched with the main control receiver.

An energy-saving method of tire pressure monitoring, comprising:

• initial match:
• supplying power to a plurality of tire pressure detectors and a main control receiver for operation when starting a car;
• wherein the plurality of tire pressure detectors are mounted on a plurality of car tires, and the main control receiver is installed in the car;
• wherein each of the tire pressure detectors has a serial number unit duplex wirelessly connected with a serial number matching unit of the main control receiver;
• first signal match:
• when the car starts to run, a detecting unit of each of the tire pressure detectors detects tire pressure and temperature of the corresponding tire and generates a first signal, and the first signal is duplex wirelessly transmitted through a first transceiver unit of the tire pressure detector to a second transceiver unit of the main control receiver;
• wherein the main control receiver generates a second signal according to a signal strength and quality of transmitting each of the first signal;
• wherein the main control receiver includes a control unit wirelessly controlling a regulating unit of each tire pressure detector to adjust and change the signal strength, receiving sensitivity or data update times of the first transceiver unit according to the second signal when transmitting the first signal;
• repeated comparison:
• during the car continuous running time, each of the tire pressure detectors continuously transmits the first signal to the second transceiver unit of the main control receiver, and continuously generates the second signal, so that the regulating unit adjusts and changes the signal strength, receiving sensitivity or data update times of the first transceiver unit when transmitting the first signal according to the second signal;
• and
• memory storage:
• after the car is turned off, a database of the main control receiver stores information, signal strength, signal quality and the serial number unit of each tire pressure detector, so that the main control receiver can directly connect to each of the tire pressure detectors for the next activation of the car.
