A monitoring network of the method includes: an intelligent antenna perception module, a filter, an amplifier, a detector, a single-chip microcomputer processing system, a Zigbee transmission module, and a WiFi transmission module. According to the monitoring network, field intensity signals of a 900M frequency band (2G communication frequency band), a 2G frequency band (3G communication frequency band), 2.4G frequency band (open communication frequency band) within one square meter can be monitored, with the development of radio communication technology and continuous exploitation and utilization of spectrum resources, more and more wireless communication systems develop towards higher carrier frequency, wider signal bandwidth, and lower radiation power, and application characteristics such as network, cellular, and local application gradually appear. Therefore, according to the grid radio monitoring technology, compared with the conventional radio monitoring technology, specific advantages are provided in refined detection, real-time analysis, evaluative determination, and scientific guarantee.

Description

technical field [0001] The invention relates to a simple hardware system for wireless frequency spectrum refined grid monitoring and an implementation method thereof, belonging to the technical field of communication. Background technique [0002] Spectrum monitoring is an important technical field of frequency domain measurement. At present, government management agencies allocate different frequency bands to various wireless services, such as: radio and television, wireless communication, mobile communication, police and emergency communication and other services. It is very important to ensure that different services work within their allocated channel bandwidth, and it is usually required that transmitters and other radiation devices should work in adjacent frequency bands. An important measurement for power amplifiers and other modules in these communication systems is to detect signal energy spillover into adjacent channels and the resulting interference. With the wid...

Problems solved by technology

[0003] Most of the existing radio monitoring systems exist in the form of fixed radio monitoring stations. Usually, the distance between monitoring stations in urban areas is relatively long, and the degree of refinement is not high, and the radio monitoring receivers are mainly suitable for For the application of monitoring analog AM / FM wireless communication, the corresponding signal bandwidth often does not exceed 200kHz, and it is impossible to monitor field strength signals of 2G communication frequency bands, 3G communication frequency bands, and open communication frequency bands, and the present invention can well solve the above problems question
