The invention provides a tagged signal transmitting and receiving circuit. A switching circuit is in communication connection with a band-pass filter circuit and the band-pass filter circuit is in communication connection with an antenna. A filter circuit comprises a receiving filter circuit and a transmitting filter circuit; a communication input end of the receiving filter circuit is in communication connection with the switching circuit; a communication output end of the receiving filter circuit is in communication connection with a communication input end of a wireless transmitting and receiving circuit; a communication input end of the transmitting filter circuit is in communication connection with a communication output end of the wireless transmitting and receiving circuit, and a communication output end of the transmitting filter circuit is in communication connection with the switching circuit. The transmitting and receiving circuit can be switched correspondingly by the switching circuit according to needs when transmitting or receiving signals, and thus processing resources of a main control circuit are saved, control efficiency is improved relatively, and energy conservation is achieved.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a tag signal transceiver circuit. Background technique [0002] Using wireless transceiver monitoring system to monitor weight is widely used in many fields. However, the existing weight monitoring systems on logistics pallets all have a fixed transceiver circuit structure, and the control unit is in continuous sending and receiving access, which not only occupies the resources of the control unit, but also does not save enough energy. For some data, continuous sending and receiving is not required. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a tag signal transceiving circuit, which solves the technical problem in the prior art that the control power supply in the fixed transceiving circuit is in continuous transceiving and accessing, resulting in waste of control unit resources. [0004] In orde...
