Description

Multifunctional environment monitor integrating temperature and humidity and sound level calibration and calibration method Technical Field The invention relates to the field of environmental monitoring and calibration, in particular to a multifunctional environmental monitor integrating temperature and humidity and sound level calibration and a calibration method. Background In the field of environmental monitoring, in particular to long-term, continuous and in-situ monitoring of key parameters such as temperature, humidity, noise and the like, the data accuracy of a monitoring instrument is fundamental to the value and the credibility of the monitoring instrument. However, due to the inherent drift, aging, and interference of complex and varying field environments of the sensor, uncertainty in the monitored data can accumulate over time, directly affecting the reliability of environmental assessment, pollution tracing, and decision support. Therefore, how to perform regular, reliable and field calibration with metering traceability (i.e. unified with national or international standard) on monitoring equipment deployed in the field on the premise of not interrupting the monitoring task and not returning the instrument to a laboratory has become a core challenge and a technical bottleneck for guaranteeing the quality of environmental monitoring network data and realizing accurate environmental management. At present, the calibration of the environment monitor mainly has the defects that firstly, the calibration and the monitoring are separated, the instrument must be periodically disassembled and sent to a fixed laboratory for calibration under standard conditions, the process is time-consuming and labor-consuming and high in cost, and continuous monitoring tasks are interrupted, so that data gaps are caused. Secondly, the in-situ traceability is lacking, the metering traceability directly related to the national standard cannot be established through on-site simple comparison or manual adjustment, and the data authority is insufficient. Thirdly, the environmental adaptability is poor, laboratory calibration conditions have great differences with complex and changeable actual deployment environments (such as temperature and humidity fluctuation, vibration and electromagnetic interference), and obvious deviation of calibration results in field application is caused, namely 'laboratory standard and field standard'. Fourth, automation and integration level are low, manual operation and experience judgment are relied on, automatic triggering, intelligent control and closed loop verification cannot be achieved, and urgent requirements of a large-scale distributed monitoring network on efficient and consistent calibration management are difficult to meet.
