Description

technical field [0001] The invention relates to the field of intelligent monitoring and automation of instruments, in particular to an intelligent switching system for temperature sensing monitoring of an array grating and a control method thereof. Background technique [0002] Array grating temperature sensing system is a high-precision, large-capacity, high-sensitivity temperature information accurate sensing alarm system based on optical fiber sensing technology. Early warning can achieve centimeter-level temperature perception, meter-level spatial positioning, and kilometer-level ultra-long-range monitoring. [0003] The working process of the array grating temperature sensing system is mainly to connect the array grating temperature sensing optical cable with the monitoring host, and the monitoring host transmits the network signal to the monitoring computer. Changes, such as laying on the surface of the oil tank, the temperature change information is transmitted to th...

Problems solved by technology

[0004] However, because the array grating temperature sensing system is used in different environments, such as cables used for high-temperature risks and oil tanks with fire hazards, there are often sudden accidents during use due to abnormal power supply on site, interruption of the site network, and accidental breakage of the sensor cable installed on site. Accidents cause the system to fail to continue to work normally, which will seriously affect its monitoring and early warning
