Problems solved by technology

[0002] In the current wireless communication, fixed-frequency communication is mostly used, but this method has poor anti-interference ability, easy data acquisition, poor communication security, and low utilization of frequency band resources. Wireless communication uses fixed frequency communication in a frequency send and receive data
If there are other devices at the same frequency or close to this frequency to transmit signals, it will cause interference to the communication. This method has poor anti-interference ability. Fixed communication at one frequency is easy to be monitored and obtained, resulting in the security of data communication. It is relatively poor. The bandwidth of wireless communication is generally below 500kHz, and the usable frequency band is generally a few MHz bandwidth. For example, the wireless frequency band of my country's power system is 471MHz to 486MHz, with a bandwidth of 15MHz, and only 500kHz of bandwidth is used. low utilization

Embodiment 1

[0043] Embodiment 1: In the 433MHZ frequency band:

[0044] A. In the 433MHZ frequency band, select n as 30 different frequency points as service frequency points, and arrange them in order to obtain the original service frequency point list N;

[0045] B. In the 433MHZ frequency band, select m to be 5 different frequency points as the beacon frequency points, and arrange them in order to obtain the beacon frequency point list M;

[0046] C. Select 5 prime numbers to obtain the prime number table P. After the arrangement is completed (prime numbers such as 7, 11, 13, 17, 19...), form a one-to-one correspondence with the arranged beacon frequency point table;

[0047] D. Select the frequency point where the serial number S of the table M is 1 as the broadcast beacon frequency point, then select the corresponding prime number P to be 11, multiply the prime number 11 by the serial number i+1 of the corresponding frequency point, and then set the frequency point Take the remainde...

Abstract

The invention discloses a multi-frequency-point communication method based on a wireless communication technology. The method comprises the following steps: obtaining a frequency band, selecting a plurality of different frequency points in the frequency band, selecting m frequency points as beacon frequency points under equal spans and forming a beacon frequency point list M{M0-Mm-1}, and additionally selecting n frequency points as service frequency points and forming a service frequency point original list N{N0-Nn-1}. According to the invention, the frequency band resource is divided into nservice frequency points and m beacon frequency points, and the service frequency points generate the non-repetitive frequency point list according to the protons, so that multi-frequency-point communication is realized, the corresponding frequency points are used in different time slots in a time slot manner, the safety and anti-interference capability of communication are improved, and the utilization rate of the resource is improved.
