The collector transceiver antenna transmits and receives the electromagnetic wave signal, completes the temperature acquisition. Signal transmission of collector and temperature sensor. Used together with the temperature collector, Ann C is installed in the same compartment of the sensor, responsible for communication with the sensor antenna, complete the sending and receiving of excitation signal and sensor signal.

The temperature collector produces the electromagnetic wave signal corresponding to the frequency of the temperature sensor. The electromagnet wave signal with temperature information returned by the temperature sensor is received and the temperature signal is analyzed and transmitted to the temperature measurement management device at the station end. The collector communicates with a group of sensors downlink and transmits RF pulse. The signal reflected by the sensors is processed in the well, and finally the effective temperature information is resolved.
