Abstract
The invention belongs to the field of aircraft wireless temperature and pressure sensors, and relates to a multi-redundancy aircraft wireless temperature and pressure sensor and a control method. The sensor comprises a multi-redundancy pressure sensitive assembly, a signal conditioning circuit, a Bluetooth transceiver module, a solid battery, a rear cover, a support and an outer cylinder. The pressure-sensitive assembly is welded to one end of the outer cylinder. The support is welded to the pressure-sensitive assembly. The Bluetooth transceiver module, the signal conditioning circuit and the solid battery are fixed on the bracket; the rear cover is in threaded connection with the outer cylinder; the pressure sensitive assembly is connected with an inner cavity of a tire through a pipeline and transmits pressure data to the signal conditioning circuit, and after the temperature measuring module measures the temperature, temperature and pressure signals are conditioned and calculated and then sent to a ground terminal through the Bluetooth receiving and transmitting module.
