Description
Technical Field
The invention relates to the technical field of environmental electromagnetic radiation monitoring, in particular to an electromagnetic radiation intermittent early warning method and system.
Background
Electromagnetic radiation is composed of spatially co-transported electrical and magnetic energy, which is generated by charge transfer. The organs and tissues of the human body have weak electromagnetic fields which are stable and orderly, and once the interference intensity of external electromagnetic radiation is overlarge, the weak electromagnetic fields in a balanced state can be influenced or even damaged; in addition, if the influence on the human body is not reached before the self-recovery, the influence degree is accumulated if the human body is influenced by the excessive electromagnetic wave radiation for a long time, and a permanent accumulation influence is formed over time. In recent years, with the emphasis on the harm of electromagnetic radiation to human bodies, monitoring of electromagnetic radiation of a communication base station has become a problem of great concern.
A complete communication base station comprises radio transmitting/receiving equipment, antennas and signal processing parts specific to all radio interfaces. Each base station antenna generally has three sectors, each sector can transmit to a certain direction and cover a certain range, each sector has one to multiple antennas, and the antennas transmit signals on one hand and receive signals transmitted from a mobile phone on the other hand. The coverage area of the communication base station is related to the power of the transmitted signal, and in order to enable the mobile terminal within the coverage area to normally receive the signal transmitted by the communication base station, the power of the transmitted signal of the communication base station needs to be higher than a minimum power level. In fact, the transmitting power of the communication base station is related to the distance and distribution of mobile terminals around the communication base station, when the distance between a call subscriber and the base station is far, the base station automatically increases the transmitting power to meet the minimum decoding power required by the mobile terminal, the electromagnetic radiation intensity around the base station is increased, when the distance between the call subscriber and the base station is close, the base station automatically reduces the transmitting power, and the electromagnetic radiation intensity around the base station is reduced.
In the prior art, the electromagnetic radiation power density of a communication base station can be predicted through the above characteristics of the communication base station, wherein a relational expression between the transmission power of the communication base station and the distance of a mobile terminal is as follows: pt＝KPrr2(ii) a In the formula, PtThe power required to be transmitted for the base station communication is W; k is the antenna-related factor in dbm; r represents the distance between the mobile terminal and the communication base station in m. The expression when monitoring the electromagnetic radiation intensity of the communication base station is as follows: S-100PtG/(4πd2) (ii) a In the formula, S represents a predicted value of electromagnetic radiation power density of a monitoring point of a communication base station; g is expressed as antenna gain in db; d is the distance between the base station and the monitoring point, and the unit is m; ptThe power required to transmit for base station communications is in units of W. The prediction mode only provides a prediction model of the electromagnetic radiation power density generated by the communication base station in the use process, and the prediction model has reference significance only to the design stage of the communication base station. The use of the above-described predictive models for the monitoring of electromagnetic radiation has not been found in the prior art for a long time.
Chinese patent 201010264317.8 discloses an electromagnetic radiation monitoring method, apparatus and system, which uses an electromagnetic radiation monitoring node to receive electromagnetic radiation signals of each frequency band near a base station and transmit the signals to a network side; and the network side receives electromagnetic radiation signals reported by all the electromagnetic radiation monitoring nodes in the whole network and judges whether the electromagnetic radiation of the electromagnetic radiation monitoring nodes monitoring the base station exceeds the standard or not. The electromagnetic radiation monitoring method is adopted, the monitored electromagnetic radiation signals are directly sent to the network side by using the radio frequency processing unit in the monitored base station, and the equipment in the base station is shared, so that the monitoring cost can be reduced, and the monitoring efficiency is improved.
In the actual monitoring implementation process, the electromagnetic radiation monitoring method disclosed in the above patent document (201010264317.8) needs to communicate with the network management platform through the network side in real time for a plurality of communication base stations in the area to be monitored, and although a specific transmission network is not adopted, the real-time transmission mode still occupies a large amount of communication bandwidth, and increases the burden of network transmission; meanwhile, all data are collected to a network management platform (control center) for analysis, and the complexity of data analysis of the network management platform is increased.
