Embodiment

[0068] Test location: Monitoring Station of Tianjin Radio Management Office, using MR3302 receiver (501) of Chengdu Zero Point Technology Co., Ltd., and equipped with Windows8 Chinese version 64-bit operating system, 4G memory, Intel Core(TM) i5-2520M2.5GHzCPU computer , built-in monitoring equipment control unit (502), transmitting equipment control unit (504), signal processing unit (503), database storage management unit (506), sub-audio encoding and decoding equipment (507), and the transmitting equipment adopts Zero Point Technology Co., Ltd. TX3010 transmitter (505). The MR3200 receiver is set to DSCAN scanning mode, the frequency range is 440MHz to 470Mhz, the scanning step is 12.5KHz, and the measurement time is 1 hour. The process is as follows:

[0069] 1. The monitoring equipment control unit (502) controls the parameters of the MR3302 receiver (501), and then begins to collect receiver signal data;

[0070] 2. The signal data is calculated by the signal processin...

Abstract

The invention provides a method and a device for supervising a radio relay station so as to solve the problems that the a conventional supervision radio relay station is large in workload, difficult to search and poor in pressing effect. Uplink and downlink signals of the relay station are searched automatically with related algorithms, infra acoustic frequency in the signals is decoded, and the relay station is interfered through emitting the uplink signals.

Description

1. Technical field [0001] The invention belongs to the field of radio monitoring, can be used for the supervision of radio relay stations, and greatly improves the efficiency of supervision work. 2. Background technology [0002] In radio management, repeater management has always been a difficult point. There are 376 U / V amateur repeaters in major cities across the country. For example, in Tianjin City, there are more than 500 legal fixed ultrashort wave stations for civil use, but no legal amateur repeaters. It is estimated that there are hundreds of illegal repeaters in the city, and many repeaters are just made up of two vehicles. A large number of private relay stations are a large source of interference. [0003] 1. Explanation of terms [0004] Sub-audio CTCSS (Continuous Tone Controlled Squelch System), continuous voice control squelch system, commonly known as sub-audio, is a technology that transmits frequencies lower than the audio frequency (67Hz-250.3Hz) in t...
