[0038] Figure 1 is a structural schematic diagram of a temperature monitoring system according to an embodiment of the present application. As shown in the figure, Figure 1 the temperature monitoring system comprises a temperature measurement module 10, a first temperature transmission module 20, a second temperature transmission module 30, a data monitoring module 40 and a first processing module 50; the input end of the temperature measurement module 10 is connected with a natural gas metering system 60; the first temperature transmission module 20 comprises a first wiring terminal 201 and a second wiring terminal 202; the first output end of the temperature measurement module 10 is connected with the first wiring terminal 201; the second output end of the temperature measurement module 10 is connected with the second temperature transmission module 30 through the second wiring terminal 202; the temperature measurement module 10 is used for measuring a first temperature and a second temperature of the natural gas metering system 60; the first temperature transmission module 20 and the second temperature transmission module 30 are both connected with the data monitoring module 40; the first temperature transmission module 20 is used for converting the first temperature into a first temperature signal and transmitting the first temperature signal to the data monitoring module 40; the second temperature transmission module 30 is used for converting the second temperature into a second temperature signal and transmitting the second temperature signal to the data monitoring module 40; the data monitoring module 40 is used for comparing the first temperature signal with the second temperature signal and monitoring a temperature offset; the first processing module 50 is connected with the data monitoring module 40; the first processing module 50 is used for outputting a prompt signal when the temperature offset is greater than or equal to an offset threshold.

[0039] In the embodiment of the utility model, the input end of temperature measuring module 10 is connected with natural gas metering system 60, the role of temperature measuring module 10 is to measure two temperatures of the same temperature point in natural gas metering system 60, namely first temperature and second temperature in real time. In the natural gas metering process, temperature is an important parameter affecting the accuracy of metering, the density and volume of natural gas will change under different temperatures, and then affect the metering result. Temperature measuring module 10 can quickly and accurately obtain the real-time temperature data of natural gas through high-precision temperature sensor. The temperature measuring module 10 in the embodiment of the utility model can output two temperature values simultaneously, improve the reliability and accuracy of temperature monitoring. Temperature measuring module 10 can be a contact temperature sensor, for example, thermocouple or thermal resistance, temperature measuring module 10 can also be a non-contact temperature sensor, for example, infrared temperature sensor or optical fiber temperature sensor.

[0040] The first temperature transmitting module 20 can be a temperature transmitter. The temperature transmitter is an instrument that converts the signal of the temperature sensor (such as a thermal resistance or a thermocouple) into a standard industrial signal (such as a 4-20 mA current or a 0-5 V voltage) for long-distance transmission, display, control or recording of temperature data. The main role of the first temperature transmitting module 20 is to convert the first temperature measured by the temperature measuring module 10 into a first temperature signal and transmit it to the data monitoring module 40. In actual application, the temperature data output by the temperature measuring module 10 is usually an analog signal or a digital signal, but these signals are easily disturbed during transmission, resulting in data distortion. The first temperature transmitting module 20 converts the temperature data into a standard signal with strong anti-interference ability, such as a 4-20 mA current signal or a 0-5 V voltage signal, through signal conversion and amplification technology, to ensure the stability and accuracy of the first temperature signal during transmission.

[0041] The second temperature transmitting module 30 receives the second temperature data of the temperature measuring module 10 through the second wiring terminal 202 and transmits the second temperature converted into a second temperature signal to the data monitoring module 40. Similarly, the second temperature transmitting module 30 optimizes the second temperature signal through signal conversion and processing technology to ensure the reliability of the signal during transmission. By setting two independent temperature transmitting modules to process the first temperature and the second temperature respectively, the mutual interference between the signals is avoided, and the accuracy of temperature signal processing is further improved. Moreover, even if one of the transmitting modules fails, the other module can still work normally, ensuring the partial normal operation of the temperature monitoring system and improving the fault tolerance and stability of the temperature monitoring system.

[0042] The data monitoring module 40 includes but is not limited to a programmable logic controller. The first temperature transmitting module 20 and the second temperature transmitting module 30 are connected with the data monitoring module 40, a control program is set in the data monitoring module 40, the first temperature signal and the second temperature signal are compared, and the temperature offset is monitored. The temperature offset can be the difference between the two temperature signals. In the natural gas metering system 60, under normal circumstances, the difference between the first temperature signal and the second temperature signal should be within a certain threshold. The data monitoring module 40 can timely find abnormal changes of temperature data by comparing the two temperature signals in real time. When the offset between the two temperature signals exceeds the offset threshold, it indicates that there can be a device failure in the temperature monitoring system, which causes the metering to deviate. The data monitoring module 40 can quickly and accurately capture these abnormal changes, provide a basis for subsequent fault diagnosis and processing, help to timely find and solve problems, and ensure the normal monitoring of the temperature monitoring system and the normal operation of the natural gas metering system 60.

[0043] The main function of the first processing module 50 is to output a prompt signal when the temperature offset is greater than or equal to the offset threshold. The offset threshold is set in advance according to the actual operation of the natural gas metering system 60 and safety requirements. For example, the offset threshold is 0.2% of the first temperature signal. For example, when the first temperature signal is 10mA, the offset threshold is 0.02mA, and when the second temperature signal is greater than or equal to 10.02mA, that is, the temperature offset exceeds the offset threshold. When the temperature offset monitored by the data monitoring module 40 reaches or exceeds the offset threshold, the first processing module 50 will immediately output a prompt signal, such as an audible and visual alarm signal or send an alarm message to the monitoring center through the network. Timely remind the operator to monitor abnormal conditions, so that the operator can quickly take measures to handle, avoid causing the metering error to expand, the equipment to be damaged, and even the safety accident to occur.

[0044] The technical scheme of the embodiment of the utility model discloses, through increasing the terminal in the first temperature transmitting module, and setting the second temperature transmitting module and connecting through the terminal, realize to the same temperature measuring point and carry out two loop individual measurement temperature, one loop as the main loop is measured, another loop as independent monitoring loop, through setting the monitoring program in the data monitoring module, real time monitoring the temperature data that two loop measured, when the temperature offset of two loop that data monitoring module received exceeds the preset threshold, the first processing module sends the prompt signal, remind staff to find and solve the problem in time, reduce the metering deviation, avoid the metering dispute, improve the metering accuracy.

On the other hand, the double-branch thermal resistor can be connected with different temperature transmitting modules respectively, so as to realize double processing and transmission of temperature data, and further enhance the stability and fault tolerance of the temperature monitoring system.
