Problems solved by technology

If the spectrum of the whole frequency band 30MHz-6000MHz is transmitted once, the data volume is 7.6Mbit, and it takes more than 77 seconds to transmit by 100Kbps satellite communication, so the real-time performance of spectrum scanning becomes very poor

Embodiment

[0025] Such as figure 1 As shown, a spectrum data compression method that can be applied to low-speed wireless network transmission, the implementation process is mainly as follows: the radio spectrum monitoring device uses the spectrum data scanned for the first time as a default template and sends it to the remote client, and sends it to the remote client During the period when the client sends the spectrum data as the default template, new spectrum scans are continuously performed, and the newly scanned spectrum data is compared with the spectrum data as the default template at each scan. If dynamic data appears in the newly scanned spectrum data The spectrum data of the dynamic data is transmitted to the remote client in a high-priority manner, and the remote client receives the complete segment of spectrum data according to the priority and returns a completion command to the radio spectrum monitoring device, and the radio spectrum monitoring device receives the completion...

Abstract

The invention discloses a spectrum data compression method applicable to low-speed wireless network transmission. A radio spectrum monitoring device uses the spectrum data scanned for the first time as a default template and sends it to a remote client, and continuously performs new spectrum scans every time. In each scan, compare the newly scanned spectrum data with the spectrum data as the default template. If dynamic data appears in the newly scanned spectrum data, the spectrum data of the dynamic data will be transmitted to the remote client with high priority. , the remote client receives the complete segment of spectrum data according to priority and returns a completion command to the radio spectrum monitoring device. After receiving the completion command, the radio spectrum monitoring device uses the currently scanning spectrum data as a new default template and repeats the above process. The method of the present invention can realize that all information in the equipment monitoring area is not lost, and realize real-time transmission and presentation of detection data under low-rate network bandwidth.

Description

technical field [0001] The invention relates to the technical field of data compression in the radio spectrum monitoring field, in particular to a spectrum data compression method applicable to low-speed wireless network transmission. Background technique [0002] When the radio spectrum monitoring equipment performs tasks in field areas without regular public communication, it uses a low-speed communication satellite network to transmit data to remote clients, and the transmission rate is generally more than 100 Kbps. If the spectrum of the whole frequency band 30MHz-6000MHz is transmitted once, the amount of data is 7.6Mbit, and it takes more than 77 seconds to transmit with 100Kbps satellite communication, so the real-time performance of spectrum scanning becomes very poor. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a spectrum data compression method app...
