[0022] Wireless temperature measurement systems are used in the power industry to monitor the heating temperature of electrical equipment and power lines. However, there are no online temperature monitoring facilities for instrument steam tracing pipelines. This makes it impossible to monitor the temperature of the steam tracing pipelines in real time during winter operation. Relying on personnel for regular inspections cannot detect faults in the tracing pipelines in time, which can easily lead to freezing and blockage of the instrument pressure tapping lines and inaccurate instrument measurements.

[0023] To address the aforementioned problems, this application proposes an automatic inspection system for the temperature of instrument steam tracing pipelines. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] Reference Figure 1This application provides an automatic inspection system for the temperature of an instrument steam tracing pipeline, including an instrument steam tracing pipeline, a wireless temperature sensor, a wireless data acquisition unit, a central control unit, and an alarm device. The wireless temperature sensor is positioned close to the instrument steam tracing pipeline and is used to monitor the temperature of the pipeline in real time, obtaining and outputting the current temperature. The wireless data acquisition unit is connected to both the wireless temperature sensor and the central control unit, receiving the current temperature from the sensor and outputting it to the central control unit. A real-time tracing temperature monitor, connected to the central control unit, receives the current temperature from the central control unit and determines whether the current temperature is below a preset minimum value. If the current temperature is below the preset minimum value, a temperature monitoring signal is generated and sent to the central control unit. The alarm device is connected to the central control unit, which also generates an alarm signal based on the temperature monitoring signal and controls the alarm device to perform an alarm operation based on the alarm signal.

[0025] It should be noted that the automatic inspection system for instrument steam tracing pipeline temperature provided in this application can achieve wireless transmission and real-time monitoring of the temperature of the instrument steam tracing pipeline, and realize automatic inspection through a real-time monitoring device for tracing temperature; specifically: wireless transmission: wireless communication technology is used between the temperature sensor and the data center, eliminating the need for wiring and simplifying installation; real-time monitoring: the system can monitor the temperature of the instrument steam tracing pipeline in real time to ensure stable operation of the instrument tracing; automatic inspection: based on the characteristics of the on-site tracing operation, a low tracing temperature alarm value is set in the monitoring system. When the tracing temperature is lower than the alarm value, the background monitoring system sends an alarm SMS to the on-duty personnel that day, notifying maintenance personnel to go to the site for handling.

[0026] In some embodiments, the wireless temperature sensor employs a high-precision temperature sensor to improve the accuracy of temperature measurement data for instrument pipeline steam tracing lines.

[0027] In some embodiments, the central control device is a cloud server.

[0028] In this embodiment, the automatic inspection system for the temperature of the instrument steam tracing pipeline also includes an instrument pipeline. The outer side of the instrument pipeline is laid parallel to or evenly wrapped with the instrument steam tracing pipeline along the pipeline direction. The probe of the wireless temperature sensor is arranged inside the insulation layer and close to the instrument steam pipeline to measure the temperature of the medium in the instrument steam tracing pipeline.

[0029] In this application, a wireless temperature sensor is used to monitor the temperature of the instrument's steam tracing pipeline in real time, obtain the current temperature, and output it. A wireless data acquisition unit is used to receive the current temperature sent by the wireless temperature sensor and output it to the central control device. A real-time heat tracing temperature monitor is used to receive the current temperature sent from the central control device and determine whether the current temperature is lower than a preset minimum value. When the current temperature is lower than the preset minimum value, a temperature monitoring signal is generated and sent to the central control device. The central control device is also used to generate an alarm signal based on the temperature monitoring signal and control the alarm device to perform an alarm operation to notify maintenance personnel to perform maintenance. Through this setup, this application can achieve automatic inspection of the temperature of the instrument's heat tracing pipeline, avoiding uncontrolled heat tracing at the instrument measuring points and preventing false readings in instrument measurements.

[0030] Reference Figure 1 It is understandable that the automatic monitoring system for the temperature of the instrument steam tracing pipeline also includes a wireless client. The wireless client is connected to the central control unit and is used to receive temperature monitoring signals sent by the central control unit.

[0031] Understandably, the automatic inspection system for the temperature of the instrument steam tracing pipeline also includes a positioning sensor. The positioning sensor is placed close to the wireless temperature sensor and is connected to the central control device. The positioning sensor is used to send the position signal of the corresponding wireless temperature sensor to the central control device, and the central control device is also used to send the position signal to the wireless client.

[0032] In some embodiments, the location signal sent by the positioning sensor includes the precise location of the wireless temperature sensor corresponding to the positioning sensor. The precise location includes at least three of the following: factory area, affiliated unit, equipment name, installation location, and tag number. The location signal and the corresponding temperature monitoring signal are sent to the wireless client together through the central control device so that maintenance personnel can promptly learn that the corresponding instrument pipeline steam tracing pipeline needs maintenance through the wireless client.

[0033] In some embodiments, the temperature of the instrument pipeline steam tracing pipeline is detected online by a wireless temperature sensor. The central control device plots a curve based on multiple real-time temperature data sent by the wireless temperature sensor. The historical data corresponding to the real-time temperature can be queried according to conditions such as temperature monitoring area, sensor name corresponding to the location sensor, and time. The query results can be exported to an Excel spreadsheet for data comparison.

[0034] Reference Figure 1 It is understandable that the automatic inspection system for the temperature of the instrument steam tracing pipeline also includes a wireless repeater, which is connected to the wireless temperature sensor and the wireless data acquisition unit respectively.

[0035] It should be noted that the wireless repeater is used for intermediate signal transmission, so as to transmit the current temperature measured by the wireless temperature sensor to the wireless data acquisition unit through the wireless repeater.

[0036] Understandably, the alarm device is an audible and visual alarm, which is used to emit both audible and visual alarm signals based on the alarm signal.

[0037] It should be noted that the audible and visual alarm, also known as an audible and visual siren, is designed to meet customers' specific requirements for alarm loudness and installation location. It can emit both audible and visual alarm signals simultaneously to alert personnel to come to the site for maintenance.
