Equipment appearance inspection: Regularly inspect the appearance of sensors, data collectors, transmission equipment, etc., to check for damage, looseness, corrosion, and other conditions. If any damage is found on the sensor housing, it should be replaced in a timely manner to prevent internal components from being damaged by moisture.

Line inspection: For wired transmission systems, check for cable damage, aging, poor contact, and other issues, and promptly repair or replace damaged cables; For wireless transmission devices, check if the antenna connection is normal and if the signal strength is stable.

Software system maintenance: Regularly update and monitor software versions, fix potential vulnerabilities, and optimize software performance. At the same time, check if the data storage and backup functions are functioning properly to ensure the security of the monitored data.

Sensor calibration: Calibrate according to the specified calibration cycle based on the type and accuracy requirements of the sensor. For example, a pressure sensor can be calibrated using a standard pressure source, comparing the measured value of the sensor with the standard pressure value, and adjusting the calibration parameters of the sensor to control its measurement error within the allowable range.

System overall calibration: After completing sensor calibration, perform joint calibration on the entire monitoring system. By simulating actual monitoring conditions, inputting known standard physical quantities, checking the accuracy of the monitoring system output data, conducting overall debugging and optimization of the system, and ensuring that the accuracy of the monitoring system meets engineering requirements.
