Boundary noise continuous monitoring system capable of self-calibration for substation

Abstract

The invention discloses a boundary noise continuous monitoring system capable of self-calibration for a substation. The boundary noise continuous monitoring system comprises a mobile monitoring terminal, a terminal installation base and an intelligent monitoring platform, wherein the mobile monitoring terminal comprises a microphone, an intelligent sound level meter, a storage unit, a processing unit, a calibration unit, a communication unit and a rechargeable power supply, and the intelligent monitoring platform comprises a data abutting unit, a database and a query unit. When the boundary noise continuous monitoring system is applied, automatic calibration of a measurement end can be performed, the reliability and the accuracy of substation boundary noise monitoring data are effectivelyimproved, meanwhile, all-weather automatic monitoring also can be achieved, and the labor is greatly saved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic noise monitoring, in particular to a self-calibrating continuous monitoring system for substation boundary noise. Background technique [0002] Noise at the boundary of a substation is an important indicator in the completion of environmental protection acceptance and environmental disputes. It is also an important basic data in noise control. The accuracy and reliability of its measurement results have a direct impact on the design, material selection and control cost of the control plan. The relationship between them, the monitoring method requires monitoring once during the day and once at night. Fixed equipment is used for substation boundary noise monitoring. The equipment costs are high, multi-point mobile monitoring cannot be performed, separate wiring is required to provide power, and maintenance costs are high. Therefore, portable equipment is generally used for manual single-poin...

Problems solved by technology

Fixed equipment is used for substation boundary noise monitoring. The equipment costs are high, multi-point mobile monitoring cannot be performed, separate wiring is required to provide power, and maintenance costs are high. Therefore, portable equipment is generally used for manual single-point short-term monitoring at present. The monitoring time is generally after 22:00, which requires monitoring personnel to go to the substation site for monitoring at 22:00, which is seriously deviated from people's normal work and rest time, and there are high safety hazards in night work, and because it is artificial The single-point measurement is disturbed by background noise, so this monitoring method not only increases the work intensity and difficulty of the measurement personnel, but also affects the reliability and accuracy of the monitoring data
