Abstract

The invention discloses a control method of a frequency-selective electromagnetic radiation monitor and relates to the technical field of electromagnetic radiation detection. The present invention includes a range selection step and a noise floor subtraction step. In the range selection step, the main controller acquires the electromagnetic radiation signal at regular intervals and calculates the maximum strength of the current signal, compares it with the end value of the current range gear range, and performs an upgrade according to the comparison result. The operation of shifting, downshifting judgment and maintaining the gear position; the downshifting judgment operation is to determine the duration of the maximum signal strength less than the minimum value of the current range gear, and if the duration reaches the configured time, the downshifting operation will be performed. The invention adopts the mechanism of steep rise and slow fall to automatically adjust the range gear, which can avoid the situation of repeated change of the range gear due to the fluctuation and change of the electromagnetic radiation signal. The invention can eliminate the influence of background noise on the measured value, so that the frequency-selective spectrum analyzer can accurately measure the electric field intensity of the current environment no matter under any conditions.

Description

technical field [0001] The invention relates to the technical field of electromagnetic radiation monitoring, in particular to a control method for a frequency-selective electromagnetic radiation monitor. Background technique [0002] With the construction of a large number of electromagnetic radiation facilities such as 5G base stations, the urban electromagnetic environment has become more and more complex. In order to implement the "Environmental Protection Law of the People's Republic of China", "Environmental Impact Assessment Law of the People's Republic of China", and "Regulations on the Administration of Environmental Protection of Construction Projects", to protect the environment and prevent environmental pollution from electromagnetic radiation, the Ministry of Ecology and Environment has approved on December 14, 2020 "5G Mobile Communication Base Station Electromagnetic Radiation Environmental Monitoring Method", which will come into force on March 1, 2021. The s...
