Abstract

The invention discloses a wireless sensor system which comprises a main control unit. The main control unit is connected with a sine wave generating unit. The main control unit can control the sine wave generating unit to generate sine waves of present frequency. The main control unit is further connected with a port selecting circuit and used for controlling a port to be connected with a first resonant capacitor or a second resonant capacitor. The first resonant capacitor or the second resonant capacitor is connected with a temperature detecting unit through an electromagnetic induction unit.The change of a load resistance value of the temperature detecting unit causes the change of a current value I1 of a receiving coil side circuit when the electromagnetic induction unit is coupled tothe receiving coil side circuit of the electromagnetic induction unit. The main control unit is further connected with a current detecting unit. The current detecting unit is used for detecting the current I1 of the receiving coil side circuit of the electromagnetic induction unit. A main controller calculates the load resistance value of the temperature detecting unit according to the current I1and then looks up a table to obtain the temperature, so wireless transmission of temperature information is realized, and a long physical connecting line is omitted.

Description

technical field [0001] The invention relates to the field of air conditioner circuits, in particular to a wireless sensor system. Background technique [0002] The current air conditioner uses a thermistor as a temperature sensing package to adjust the working state of the motor according to the measured ambient temperature or coil temperature. At present, the temperature-sensing package of the air conditioner is connected to the main control unit through a physical connection, so as to transmit the temperature signal. However, with the increasing scale of air-conditioning manufacturers, the increasing number of air-conditioning models, and the changes in structural components, a single-length temperature-sensing package is no longer sufficient. At the same time, there are many sheet metal parts inside the air conditioner, and physical connections are used, so there is a risk of wear and tear. Based on the above considerations, the present invention proposes a wireless sen...
