Preferably: also included is a repeater disposed between the controller assembly and the wheel side valve assembly.
Preferably: the vehicle instrument includes a display and a console.
The control method of the real-time tire pressure monitoring system of the heavy off-road vehicle based on central inflation and deflation comprises the following steps:
the first step is as follows: the repeater receives data signals of the temperature and the pressure value in the tire, which are measured by the pressure and temperature sensor of the wheel edge valve assembly and then sent out by the wireless signal transceiver;
the second step is that: the repeater reinforces the received data signal of the wheel edge valve assembly and then transmits the data signal to the controller assembly;
the third step: when the controller assembly is in a working state, after the controller assembly receives a data signal, the controller assembly sends a feedback signal of successful receiving to the wheel valve assembly, the controller assembly transmits the received data signal to the vehicle instrument, and the vehicle instrument displays the data signal and gives an instruction signal for air release or inflation; when the controller is always in a closed state, the wheel edge valve assembly does not receive a feedback signal of successful receiving sent by the controller, and the wheel edge valve assembly automatically enters a standby state;
the fourth step: and the controller always receives the instruction signal of deflation or inflation and then controls the wheel valve assembly to perform instruction operation of deflation or inflation through the air pipeline.
Preferably: the controller assembly sends the tire pressure detection related information received from the wheel side valve assembly to the vehicle instrument, the vehicle instrument can display the information after analysis and send an alarm after logical judgment of air leakage.
Compared with the prior art, the utility model has the following beneficial technical effects:
the utility model can detect the tire pressure of the tire, and also can detect the wheel edge temperature of each tire, if the displayed temperature is too high, the abrasion of the corresponding tire is serious, and a driver is reminded to check the reason of the abrasion; in addition, when the tire is flat or the heavy off-road vehicle can run in a flat state, the alarm is given through a vehicle instrument; a repeater is adopted to strengthen wireless signals, and an auxiliary controller assembly is connected with a wheel edge valve assembly; when a power switch of the controller assembly is in an off state, the wheel valve assembly cannot receive a feedback signal that a pressure and temperature signal sent by the wheel valve assembly is successfully received, and then automatically enters a silent state, and a wireless signal is not transmitted outwards, so that the influence on other functions of the vehicle due to the abnormal wireless signal under a special working condition is avoided.
