The signal input end of the amplifying unit is connected with the coding frequency shift signal output end of the transmitter and used for amplifying the coding frequency shift signal output by the transmitter and then outputting a power amplifier signal. The back-extraction unit is used for collecting the power amplification signals output by the amplification unit and outputting collection parameters.
Specifically, in this embodiment, the amplifying unit is in the form of a transformer. Specifically, the winding device comprises an input winding 1, an output winding and an iron core 2. Wherein, input winding 1 and output winding are all wound on iron core 2. The signal input end of the input winding 1 is connected with the coding frequency shift signal output end of the transmitter and is used for receiving the coding frequency shift signal output by the transmitter. The output winding is used for amplifying the coded frequency shift signal and then outputting a power amplifier signal.
More specifically, the input winding 1 includes a first input coil 1-1 and a second input coil 1-2. Wherein the first input coil 1-1 has terminal numbers 1 and 2, and the second input coil 1-2 has terminal numbers 3 and 4. And the No. 2 terminal and the No. 3 terminal are connected in series, so that the first input coil 1-1 and the second input coil 1-2 are connected in series and then are connected with the coded frequency shift signal output end of the transmitter. The output winding consists of an output coil 3. Six coil terminals, 1, 2, 3, 4, 5, and 6, are drawn out from the output coil 3. And corresponding voltage values are output between every two adjacent coil terminals according to the voltage values input to the winding 1.
For example, in the present embodiment, the rated voltage of the first input coil 1-1 and the second input coil 1-2 are both 13V. Then, when the first input coil 1-1 and the second input coil 1-2 are used in series such that the input voltage value of the input winding 1 is 26V, the voltage between the terminal No. 1 and the terminal No. 2 of the output winding is 82.8V, the voltage between the terminal No. 2 and the terminal No. 3 is 33.1V, the voltage between the terminal No. 3 and the terminal No. 4 is 27.5V, the voltage between the terminal No. 4 and the terminal No. 5 is 21.5V, and the voltage between the terminal No. 5 and the terminal No. 6 is 18.9V. Therefore, the requirements of 1-level to 5-level electrical levels of the coded frequency shift signal power amplification signal output by the transmitter are met.
Further, in this embodiment, the recovery unit may be configured to perform two-way collection, that is, two recovery units may be provided. Each recovery unit includes a recovery coil 4. The extraction coil 4 is wound around the core 2. The extraction coil 4 can collect power amplifier signals, including frequency and amplitude. When the input voltage value of the input winding 1 is 26V, the output voltage of the extraction coil 4 is 1.5V.
