Description

Technical Field

[0001] This application relates to the field of cable monitoring technology, and in particular to a temperature monitoring system and a temperature monitoring method. Background Technology

[0002] During the kiln production process, multiple high-power cables are required for electric heating. These cables, laid in cable trays, generate their own heat during the kiln heating process. Furthermore, due to the high-temperature environment of the kiln, the surface temperature of the cables can reach over 80°C. If the cables operate at temperatures above 80°C for extended periods, it will accelerate the aging of the cable insulation, eventually leading to breakdown or even a fire. Therefore, to ensure cable safety, cable temperature monitoring is necessary. However, current technologies often rely on manual, periodic measurements of cable temperature at specific points using infrared imagers after opening the cable trays. This method not only fails to comprehensively obtain temperature information for all cables but also struggles to guarantee the accuracy of the collected data. Summary of the Invention

[0025] During the kiln production process, multiple high-power cables are required for electric heating. These cables, laid in cable trays, generate their own heat during the kiln heating process. Furthermore, due to the high-temperature environment of the kiln, the surface temperature of the cables can reach over 80°C. If the cables operate at temperatures above 80°C for extended periods, it will accelerate the aging of the cable insulation, eventually leading to breakdown or even a fire. Therefore, to ensure cable safety, cable temperature monitoring is necessary. However, current technologies often rely on manual, periodic measurements of cable temperature at specific points using infrared imagers after opening the cable trays. This method not only fails to comprehensively obtain temperature information for all cables but also struggles to guarantee the accuracy of the collected data.

[0026] Based on this, this application provides a temperature monitoring system and a temperature monitoring method that can comprehensively monitor the status information of cables and improve the efficiency and accuracy of monitoring.

[0027] Next, the temperature monitoring system and temperature monitoring method provided in the embodiments of this application will be further described.

[0028] First, please refer to Figure 1 The diagram illustrates a temperature monitoring system according to an embodiment of this application. Figure 1 As shown, the temperature monitoring system 10 includes: a cable tray 101, a cable (not shown in the figure), and a temperature-measuring optical fiber 102. The cable is laid within the cable tray 101 and is used to output heat. Understandably, a high-power cable can be selected to electrically heat the kiln production line 100 to meet its production needs.

[0029] In one embodiment of this application, the cable tray 101 includes a main cable tray, an upper cable tray, and a lower cable tray, with one end of each of the upper and lower cable trays connected to one end of the main cable tray. The cable tray 101 extends from the control room 200 to the kiln production line 100, and is divided into upper and lower layers within the kiln production line 100. The upper cable tray is located above the kiln production line 100, and the lower cable tray is located below the kiln production line 100. The upper and lower cable trays are connected via the main cable tray. The starting end of the cable is connected to the control room 200, and the cable extends through the cable tray 101 to the kiln production line 100. The cable tray 101 may contain one or more cables; this application does not limit the number of cables.

[0030] For example, the temperature-sensing optical fiber 102 is laid on the cable and is used to collect the cable's status data. This status data includes the coordinates of monitoring points and the corresponding temperature data. The monitoring point coordinates accurately reflect the cable's spatial distribution, allowing for a clear understanding of the geographical location of different cable sections, facilitating rapid identification of abnormal locations for maintenance. The monitoring point coordinates can be represented using a two-dimensional or three-dimensional coordinate system. For example, a coordinate system can be established with the starting end of the temperature-sensing optical fiber 102 as the origin or with other set reference points as the origin. This application does not limit the specific method of establishing the coordinate system. The monitoring point coordinates can also be determined based on the length of the temperature-sensing optical fiber 102. This application does not limit the specific representation of the monitoring point coordinates. The temperature data reflects the temperature changes of the cable during operation. By monitoring the temperature data in real time, overheating of the cable can be detected promptly. The temperature-sensing optical fiber 102 can sense the ambient temperature by monitoring changes in the characteristics of the light transmitted within it (such as light intensity and phase). When the temperature at the location of the temperature-sensing optical fiber 102 changes, it will cause a corresponding change in the optical signal within the temperature-sensing optical fiber 102. The temperature-sensing optical fiber 102 can be made of high-temperature resistant optical fiber, and its surface coating can be made of thermoplastic polyester elastomer (TREE), also known as polyester rubber or TPC-ET, which has properties such as resistance to bending fatigue, impact resistance, and chemical corrosion resistance. The temperature-sensing optical fiber 102 can also be made of other materials suitable for the high-temperature environment of the kiln; this application does not limit the specific material of the temperature-sensing optical fiber 102.

[0031] In one embodiment of this application, the cable includes a first cable portion, the bending angle of which is... The angle is greater than or equal to a preset angle. The temperature-sensing optical fiber 102 includes a first temperature-sensing optical fiber 1021, which is laid in a curved shape on the surface of the first cable section. Understandably, when the bending angle... When the angle is 180°, the cable is laid in a straight line. However, during installation and operation, cables often bend due to route requirements, such as at the bends in cable tray 101, where the cable undergoes bending deformation. This can be addressed by detecting the cable's bending angle. This method can effectively determine whether the cable has deformed and the degree of deformation, and its impact on the cable surface's temperature resistance. The first temperature-sensing optical fiber 1021 can be laid in an S-shaped curve on the surface of the first cable section. Understandably, compared to a straight-line laying method that only covers a portion of the cable within the cable tray 101, the S-shaped curve laying method effectively increases the temperature-sensing area of ​​the cable, ensuring that all cables within the cable tray 101 can be temperature-sensing via the temperature-sensing optical fiber 102. Simultaneously, compared to a straight-line laying method, the S-shaped bend of the temperature-sensing optical fiber 102 allows for a denser density of temperature-sensing points. For example, if temperature-sensing points are set at 0.5-meter intervals on the temperature-sensing optical fiber 102, a straight-line laying method can only monitor cable status data every 0.5 meters, while the S-shaped curve laying method can effectively set more monitoring points on cables of equal length, improving monitoring accuracy and efficiency. The degree of bending of the temperature-sensing optical fiber 102 can be set according to measurement requirements and is not fixed to the specific bending angle of the temperature-sensing optical fiber 102. Restrictions should be imposed.

[0032] In one embodiment of this application, the cable further includes a second cable portion, the first cable portion being connected to the second cable portion, and the bending angle of the second cable portion is... The angle is less than a preset angle. The temperature-sensing optical fiber 102 includes a second temperature-sensing optical fiber 1022, which is arranged around the surface of the second cable portion. Understandably, during cable laying, there are varying degrees of bending deformation, such as the cable's bending angle. The angle is 90°, etc. This application does not limit the specific size of the preset angle. The second temperature-sensing optical fiber 1022 can be laid in a circular multi-turn pattern to achieve a ring-shaped arrangement around the surface of the second cable. This circular multi-turn arrangement allows for the measurement of state data at cable bends, effectively increasing the monitoring area and improving measurement accuracy. The circular multi-turn arrangement allows the temperature-sensing optical fiber 102 to be spirally or circularly wound around the cable surface, forming multiple loops. Each loop of the temperature-sensing optical fiber 102 is in close contact with the surface of the object being measured, ensuring accurate temperature signal transmission and achieving omnidirectional, continuous, and high-precision measurement. The number of loops of the temperature-sensing optical fiber 102 can be adjusted according to measurement requirements; this application does not limit the specific number of loops.

[0033] like Figure 1 and Figure 2As shown, the temperature monitoring system 10 also includes a control terminal 103, which is connected to the temperature-sensing optical fiber 102. The control terminal 103 is used to acquire status data. The control terminal 103 includes a temperature-sensing host 1031 and a data management device 1032. The temperature-sensing optical fiber 102 is connected to the optical fiber port of the temperature-sensing host 1031, and the data management device 1032 is communicatively connected to the temperature-sensing host 1031. The temperature-sensing host 1031 is used to receive the status data collected by the temperature-sensing optical fiber 102 and transmit it to the data management device 1032. Users can query the status data through the data management device 1032. The temperature-sensing host 1031 can be installed in the control room 200. The communication connection can include wired communication connections such as Ethernet or fiber optic networks, or wireless communication connections such as WiFi or Bluetooth. This application does not limit the specific method of communication connection.

[0034] In one embodiment of this application, the data management device 1032 includes a server 1032a and a monitoring and management device 1032b. The server 1032a can be a dedicated virtual server deployed in a hyperconverged infrastructure (HCI). The temperature measurement host 1031 can be connected to the industrial control network via an industrial control switch, thereby enabling interconnection between the server 1032a and the temperature measurement host 1031 to obtain status data from the temperature measurement host 1031. The server 1032a can also be other types of servers; this application does not limit the specific form of the server 1032a. Users can query status data through the monitoring and management device 1032b. The monitoring and management device 1032b can be a fiber optic temperature measurement management platform deployed on the virtual server, and users can query data through web pages or software. The monitoring and management device 1032b can also be a physical device; this application does not limit the specific form of the monitoring and management device 1032b.

[0035] For example, the control terminal 103 also includes a monitoring and alarm device 1033, which is communicatively connected to the temperature measuring host 1031. The monitoring and alarm device 1033 can be in the form of a webpage or software, such as a Supervisory Control And Data Acquisition (SCADA) platform. The SCADA platform is a core tool for remote control in the industrial field. Its core value lies in centralized monitoring, data acquisition, and automated / semi-automated control of remote industrial equipment, ensuring stable and efficient operation of industrial processes. The SCADA platform has functions such as data acquisition and processing, remote monitoring and visualization, remote control and adjustment, and alarm and event management. The monitoring and alarm device 1033 can be connected to the temperature measuring host 1031 through an industrial control network. The monitoring and alarm device 1033 uses the MODBUS RTU protocol to obtain status data from the temperature measuring host 1031. The MODBUS RTU protocol is a serial communication protocol widely used in industrial automation, supporting master-slave communication mode, and is usually implemented through RS485 or RS232 interfaces. It is widely used for data exchange between devices due to its high efficiency, stability, and simplicity. The monitoring and alarm device 1033 can also be a hardware device; this application does not limit the specific form of the monitoring and alarm device 1033. The monitoring and alarm device 1033 and the temperature measuring host 1031 can also communicate via WiFi, Bluetooth, or Ethernet; this application does not limit the specific connection method between the monitoring and alarm device 1033 and the temperature measuring host 1031. When abnormal status data occurs, the monitoring and alarm device 1033 alerts the user, who can view the alarm information on the monitoring and alarm device 1033 and perform timely cable maintenance. Users can also query current and historical alarm information through the monitoring management device 1032b for comprehensive cable evaluation. For example, the maintenance frequency corresponding to the monitoring point coordinates can be analyzed based on the current and historical alarm information, and the corresponding future maintenance time can be predicted, facilitating advance maintenance planning and improving maintenance efficiency. The future maintenance time can be predicted using linear regression models or neural network models; this application does not limit the specific prediction model. The comprehensive assessment may also include other parameters that can be obtained by analyzing current alarm information and historical alarm information. This application does not limit the specific content of the comprehensive assessment.

[0036] In one embodiment of this application, such as Figure 3 As shown, after the temperature-sensing optical fiber 102 is laid, the user can draw a configuration diagram of the temperature-sensing optical fiber 102 on the data management device 1032 and mark the position of the temperature-sensing optical fiber 102 in the configuration diagram, such as... Figure 3The calibration is performed based on the length of the temperature-sensing optical fiber 102 to ensure that the actual position of the temperature-sensing optical fiber 102 at the kiln site matches the position information in the configuration diagram. Figure 4 Taking the magnified detail image in the image as an example, Figure 3 The other straight sections are all first temperature-sensing optical fibers 1021, laid out in an S-shaped curve. The corner sections are all second temperature-sensing optical fibers 1022, laid out in a circular multi-turn pattern. Due to the high ambient temperature of the kiln, it is difficult to identify the specific location of the temperature-sensing optical fibers 102 by heating, and this can easily cause them to overheat and be damaged. Therefore, the temperature-sensing optical fibers 102 can be cooled, and the corresponding location data can be determined based on the temperature drop. When the accuracy of the temperature-sensing optical fiber 102 is 0.5 meters, the entire 0.5-meter section needs to be cooled simultaneously to lower the measured temperature. Since the temperature-sensing optical fibers 102 are laid out in an S-shaped curve and a circular multi-turn pattern, they can be cooled simultaneously after being wound in circles. Cooling methods can include cooling sprays or wrapping ice blocks in towels; this application does not limit the specific operation of the cooling method. When the temperature of the temperature-sensing fiber optic cable 102 decreases, the data management device 1032 can quickly acquire the corresponding monitoring point location. For example, the data management device 1032 can acquire the monitoring point location in approximately 5 seconds, thereby achieving position calibration on the configuration diagram and determining the coordinates of the monitoring point. In this way, by acquiring the position of the temperature-sensing fiber optic cable 102 through cooling processing, the actual position can be more accurately associated with the position in the configuration diagram, reducing the probability of error due to manual selection of positions in the configuration diagram, improving the adaptability of the temperature monitoring system 10 to the kiln production line 100, and increasing the accuracy of the monitoring points.

[0037] Those skilled in the art will understand that the schematic diagram is merely a structural example of the temperature monitoring system 10 and does not constitute a limitation on the temperature monitoring system 10. The temperature monitoring system 10 may also include more or fewer other hardware or software, or different component arrangements than shown in the diagram. For example, the temperature monitoring system 10 may also include input / output devices, network access devices, etc.

[0038] Please refer to the following: Figure 1 and Figure 5 This application provides a temperature monitoring method, implemented by a temperature monitoring system 10 as described in any of the above embodiments, the temperature monitoring method including the following steps S1 to S2.

[0039] Step S1: Obtain the status data of the cable through the temperature-measuring optical fiber; wherein, the status data includes the coordinates of the monitoring point and the corresponding temperature data.

[0040] For example, before acquiring the cable status data, the temperature-sensing optical fiber undergoes multiple cooling processes to obtain corresponding calibration temperature data. The coordinates of the corresponding monitoring point are determined based on each calibration temperature data point. Status data can be monitored at set intervals, such as once every 20 seconds or once per minute; this application does not limit the specific value of the set interval. In this way, this application can collect status data for all cables in real time, improving the comprehensiveness and real-time performance of data acquisition.

[0041] Step S2: Compare each temperature data with the temperature threshold. When the temperature data is greater than or equal to the temperature threshold, determine the corresponding monitoring point coordinates as an abnormal location and output an alarm reminder.

[0042] For example, this application does not impose excessive limitations on the temperature threshold. Those skilled in the art can set it based on actual needs, such as, but not limited to, setting the temperature threshold to... wait.

[0043] In one embodiment of this application, the temperature change rate is determined based on the temperature data of each monitoring point coordinate within a preset time period. For example, all temperature data monitored within 10 minutes can be retrieved; this application does not limit the specific preset time period. The temperature change rate can be the real-time rate of temperature rise or the average rate obtained from multiple monitoring sessions; this application does not limit the specific calculation method of the temperature change rate. When the temperature change rate is greater than or equal to a preset standard rate, the corresponding monitoring point coordinates are determined to be an abnormal location, and an alarm is output. This application does not impose many limitations on the standard rate; those skilled in the art can set it based on actual needs, such as, but not limited to, setting the standard rate to... wait.

[0044] Understandably, Figure 5 The specific implementation methods of each step shown are similar to those in the above embodiments, and will not be repeated here.

It executes programs or modules stored in the memory 3001 (e.g., executing a passage area prediction program) and calls data stored in the memory 3001 to perform various functions and process data of the electronic device 300.

[0049] Understandably, all or part of the processes operating the electronic device 300 can be executed by instructing related hardware through a computer program, which can be stored in a computer-readable storage medium. The computer program includes computer-readable instruction code, which can be in the form of source code, object code, executable files, or some intermediate form.
