On-line electromagnetic radiation long-term monitoring system

Abstract

The invention discloses an on-line electromagnetic radiation long-term monitoring system which comprises an electromagnetic radiation monitor, a solar power supply unit and a first photoelectric converter, wherein the electromagnetic radiation monitor, the solar power supply unit and the first photoelectric converter are fixed to the top end of a support frame component. The on-line electromagnetic radiation long-term monitoring system further comprises a far-end control box, a far-end second photoelectric converter, a data acquisition unit, a communication device and a power supply system, wherein the data acquisition unit, the communication device and the power supply system are arranged inside the control box. The support frame component is an insulator. The solar power supply unit is electrically connected with the electromagnetic radiation monitor and supplies power to the electromagnetic radiation monitor. The first photoelectric converter is connected with the far-end second photoelectric converter through optical fiber. The power supply system is electrically connected with the data acquisition unit and the communication device and supplies power to the data acquisition unit and the communication device. According to the on-line electromagnetic radiation long-term monitoring system, power supply of the monitoring terminal and the control terminal are separated from power supply structural layout, and an independent power supply structure is used so that it can be guaranteed that the monitoring system operates continuously for a long time; meanwhile, the monitoring system is far away from metal objects, and measurement errors which are caused due to the fact that an electromagnetic radiation monitor in the prior art is externally connected or is close to a metal conductor can be effectively avoided.

Description

technical field [0001] The invention relates to the field of electromagnetic radiation monitoring, in particular to an online long-term monitoring system for electromagnetic radiation. Background technique [0002] In recent years, the public has paid more and more attention to the safety of the electromagnetic environment of large-scale electromagnetic facilities such as mobile communication base stations, high-voltage power transmission and transformation facilities, and radio and television transmission facilities. Complaints, conflicts and public anxiety about the electromagnetic environment pollution of large-scale electromagnetic facilities have been increasing year by year trend. In order to reverse the passive situation of monitoring after receiving complaints from the public, environmental protection departments, mobile communication operators, power departments and radio and television departments expect to conduct online monitoring of the electromagnetic radiation...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing electromagnetic radiation monitors are all suspended design. If there is a metal object near the probe, the metal object will cause the distortion of the electromagnetic field, resulting in measurement error

[0005] 2. The electromagnetic radiation monitor is used for electromagnetic radiation monitoring, so wireless communication cannot be used between the electromagnetic radiation monitor and the data acquisition device (that is, the data acquisition device), because the wireless emission (that is, electromagnetic waves) close to the electromagnetic radiation monitor will cause electromagnetic radiation. Errors in Radiation Measurements

However, because the wireless communication system will cause errors in the measurement of electromagnetic radiation, and usually the solar power supply system is designed with a small size to reduce the measurement error of the solar power supply system, its power supply capacity is very limited, but the solar power supply system with limited power supply capacity must be electromagnetic The radiation detector also needs to supply power for data acquisition devices and other equipment, so it cannot guarantee to supply power to the electromagnetic radiation monitoring system for a long time to maintain its normal work

Therefore, the existing long-term electromagnetic radiation monitoring system can only transmit wirelessly once every long period of time, such as a day. Unable to respond in time when there is a permanent electromagnetic radiation event, and secondly, normal electromagnetic radiation monitoring cannot be carried out during the wireless transmission time period
