Problems solved by technology

[0003] Traditional one-way electric buoys send carrier frequency signals regularly. This method has the problems of large errors and easy generation of co-frequency interference, and ineffective transmission greatly wastes battery resources.
Although the existing paging-response electric buoy overcomes the above-mentioned shortcomings of the one-way electric buoy, the circuit is complicated, and most of the components are plug-in or customized parts, which are poor in mass production. In addition, in terms of data transmission and reception, there is no perfect Unified data sending and receiving mechanism

Embodiment 1

[0057]In Embodiment 1, the call code sent by the calling machine of the mother ship is "1234", and four codeword frequencies of 506Hz, 528Hz, 561Hz and 590Hz are obtained in turn. The paging code frequency corresponding to the 4 codewords "4973" of the code (respectively: the paging code frequency f corresponding to the codeword "4" 4 577.5≤f 4 9 727.5≤f 9 7 is 667.5≤f 7 3 is 547.5≤f 3 <577.5Hz) is inconsistent, indicating that the call code sent by the caller of the mother ship does not match the paging code set by the electric buoy, and the electric buoy remains in the data receiving state.

Embodiment 2

[0058] In Embodiment 2, the call code sent by the calling machine of the mother ship is "4973", and four codeword frequencies of 597Hz, 741Hz, 680Hz and 565Hz are obtained in turn. The paging code frequency corresponding to the 4 codewords "4973" of the code (respectively: the paging code frequency f corresponding to the codeword "4" 4 577.5≤f 4 9 727.5≤f 9 7 is 667.5≤f 7 3 is 547.5≤f 3 <577.5Hz) are consistent, the microcontroller 8 receives the data of the square wave signal, the antenna switch 2 switches to the data transmission loop, and the DDS generator 9 switches to the FSK transmitting module through the radio frequency switch; in embodiment 2, step 5-step 8 as follows:

[0059] Step 5: the microcontroller 8 turns on the power supply of the GPS module 15, and starts the timer on the microcontroller 8 to start timing, and the microcontroller 8 waits for the GPS module 15 to send effective GPS information, and the effective GPS information includes the position longi...

Description

technical field [0001] The invention relates to a data sending and receiving method, in particular to a data sending and receiving method of a remote control radio buoy. Background technique [0002] Radio buoys mainly locate fishery production operations, and can be divided into one-way electric buoys and paging response electric buoys according to their working methods. There is a transmitter in the one-way electric buoy, and the electric buoy regularly sends information to the receiver on the mother ship. The receiver receives the information from each buoy to obtain the number of the electric buoy and calculates the position of the electric buoy away from the bow of the mother ship. There are both transmitters and receivers in the paging response electric buoy. The specific working method is: when the mother ship wants to inquire about the position of a certain electric buoy, it sends a specific paging code to the electric buoy, and when the electric buoy receives the W...
