[0002] During the operation of electrical appliances, the heat generated by the appliances themselves will affect their performance, sometimes causing local discharge and burning. At the same time, it will accelerate the deterioration of electrical insulation and cause great economic losses to the power system.

[0003] Remote monitoring can promptly detect problems with remote electrical systems. For example, if there is high temperature on the remote electrical system, timely detection can help eliminate the fault. Therefore, remote monitoring is very important, and the accuracy of monitoring is also very important.

[0004] The electrical temperature online monitoring system includes multiple distribution rooms and monitoring rooms. The distribution rooms are equipped with electrical appliances. There is also a temperature sensor for measuring electrical temperature in the distribution rooms. The temperature sensor is connected to a signal converter. The signal converter can convert the temperature signal measured and transmitted by the temperature sensor into an electrical signal. The signal converter is connected to a first signal transceiver. The monitoring room is equipped with a second signal transceiver. The first signal transceiver and the second signal transceiver are matched and connected through a network.

[0005] In the prior art, the data transmitted by the temperature sensor detected in the monitoring room is used directly. However, in practice, the monitored data is sometimes inaccurate. For example, due to the influence of factors such as the failure of the network of the first signal transceiver and the second signal transceiver, the sensitivity of the temperature sensor, etc., the temperature signal received by the second signal transceiver deviates from the actual temperature of the electrical appliance, and the electrical temperature cannot be accurately detected, and the data cannot be verified, which has the disadvantages of uncertain credibility and doubts in use. Summary of the invention

[0006] The purpose of the present invention is to address the above shortcomings and provide an electrical temperature online monitoring system and an electrical temperature online monitoring method that can measure the reliability of the temperature measured by the temperature sensor.

[0007] The technical solution of the electrical temperature online monitoring system of the present invention is implemented as follows: the electrical temperature online monitoring system includes a distribution room and a monitoring room, the distribution room has electrical equipment, and a temperature sensor for measuring electrical temperature is also installed in the distribution room, the temperature sensor is connected to a signal converter, the signal converter can convert the temperature signal measured and transmitted by the temperature sensor into an electrical signal, the signal converter is connected to a first signal transceiver, the monitoring room has a second signal transceiver, the first signal transceiver and the second signal transceiver match each other and are connected through a network; its characteristic is that: the distribution room is also equipped with a temperature variable component, the temperature variable component can change the temperature of the part measured by the temperature sensor, the temperature variable component is connected to a power supply through a control device, the control device is connected to the first signal transceiver, and the second signal transceiver can control whether the temperature variable component works through the first signal transceiver and the control device.

[0008] Furthermore, the temperature-changing component includes a temperature-raising component and a temperature-lowering component.

[0009] Furthermore, the electrical device is installed on a board, and there is an operating component on the board. The control device is connected to the operating component and controls the operation of the operating component, and the temperature sensor is installed on the operating component. When the operating component is in one station, the temperature sensor can measure the temperature of the electrical device, and this station is the first station. When the first operating component is running and the first operating component is in another station, the temperature sensor can measure the temperature of the temperature-changing component, and this station is the second station.

[0010] Furthermore, the temperature-changing components installed on the board surface include a heating component and a cooling component; there is another workstation in front of the second workstation, which is the third workstation. When the component is operated to the third workstation, the temperature sensor can measure the temperature of the temperature-changing component; this temperature-changing component is the opposite of the temperature-changing component of the second workstation, that is, if the temperature measured at the second workstation is a heating component, then the temperature measured at the third workstation is a cooling component; if the temperature measured at the second workstation is a cooling component, then the temperature measured at the third workstation is a heating component.

[0011] After the detection is completed, the control device returns the temperature sensor to the position for electrical detection.

[0012] Further, the temperature-changing component is a temperature-changing component that changes a certain temperature within a certain period of time, and the temperature change of the temperature-changing component within a certain period of time is a changing parameter.

The second signal transceiver device can compare the test changing parameter with the correct changing parameter, and output or display the test result.

[0013] Furthermore, under the action of the control device, after the above detection is completed, the control device causes the temperature sensor to return to the first position.

[0014] The technical solution of the method for online monitoring of electrical temperature of the present invention is implemented as follows: the method for online monitoring of electrical temperature uses a temperature sensor to measure the temperature of the electrical component, and transmits the temperature signal measured by the temperature sensor to a remote monitoring room through a network. A temperature variable component is installed near the electrical component. The temperature variable component is turned on to check whether the temperature signal transmitted by the temperature sensor monitored by the monitoring room changes synchronously; if the temperature signal of the temperature sensor measured by the monitoring room changes synchronously, it means that the signal transmission is relatively true and reliable, and the credibility is high; if the temperature signal of the temperature sensor measured by the monitoring room does not change synchronously, it means that the signal transmission is relatively untrue and the credibility is low.

[0015] Furthermore, the synchronous change of the temperature signal of the temperature sensor measured in the monitoring room includes two processes, which are the temperature rising process measured by the temperature sensor for the temperature rising component and the temperature falling process measured by the temperature sensor for the temperature falling component.

[0016] Furthermore, the synchronous change also includes whether the temperature signal of the sensor measured in the monitoring room is consistent with the temperature rise value of the preset temperature-changing component within a certain period of time.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 , 2 As shown in Figure 3, the electrical temperature online monitoring system includes a distribution room 1 and a monitoring room 2, wherein the distribution room has an electrical 3, and a temperature sensor 4 for measuring the electrical temperature is also installed in the distribution room, wherein the temperature sensor is connected to a signal converter, wherein the signal converter can convert the temperature signal measured and transmitted by the temperature sensor into an electrical signal, wherein the signal converter is connected to a first signal transceiver 5, wherein the monitoring room has a second signal transceiver 6, wherein the first signal transceiver and the second signal transceiver match each other and are connected through a network; wherein the distribution room is also equipped with a temperature-changing component 7, wherein the temperature-changing component can change the temperature of the part measured by the temperature sensor, wherein the temperature-changing component is connected to a power supply via a control device, wherein the control device is connected to the first signal transceiver, wherein the second signal transceiver can control whether the temperature-changing component works through the first signal transceiver and the control device.

[0024] Principle of use: When the present invention is used, a temperature sensor can be used to measure an electrical temperature first. This temperature is transmitted to the monitoring room through the signal converter, the first signal transceiver device, and the second signal transceiver device. The temperature of the electrical equipment will be known in the monitoring room, but the credibility of this temperature is unknown. The following scheme is adopted; that is, in the monitoring room, by controlling the second signal transceiver device, the first signal transceiver device, and the control device, the temperature-changing component is turned on. The temperature-changing component is a heating component 71 or a cooling component 72. For example, the heating component is a heating tube, and the cooling component is a refrigeration plate (a part that can lower the temperature in temperature regulation). In this way (under normal circumstances), the data measured by the temperature sensor can change with the change of the temperature of the temperature-changing component. If the monitoring room measures this phenomenon, it means that the electrical temperature online monitoring system is basically reliable.

[0025] The temperature sensor is a component in the prior art, which can measure the temperature of an object.

[0026] In summary, the temperature sensor is used to measure the temperature change of the temperature-changing component to detect whether the temperature sensor and the monitoring system are normal.

[0027] Furthermore, the temperature changing component includes a temperature increasing component 71 and a temperature decreasing component 72 .

[0028] That is, on the one hand, it can be detected by increasing the temperature, and on the other hand, it can be detected by decreasing the temperature.

[0029] Further speaking, if Figure 2 As shown, the electrical device is installed on a board, and there is also a running component 8 on the board. The control device is connected to the running component and controls the operation of the running component. The temperature sensor is installed on the running component. The direction of arrow F in the figure is the running direction of the running component. When the running component is in one station, the temperature sensor can measure the temperature of the electrical device, and this station is the first station 91. When the running component is running and the running component is in another station, the temperature sensor can measure the temperature of the temperature-changing component, and this station is the second station 92.

[0030] The present invention is arranged in this way, so that in the process of checking the measured temperature, the temperature measured by the temperature sensor is the temperature of the variable temperature component. Because the electrical temperature is generally larger, that is, the heat capacity is larger. If the temperature sensor measures the temperature change of the electrical temperature, the temperature change of the variable temperature component has a smaller effect on the temperature change of the electrical temperature, that is, the temperature change of the electrical temperature is smaller, and sometimes the measurement is inaccurate. After the first workstation is changed to the second workstation, the temperature sensor measures the temperature of the variable temperature component. Since the temperature change of the variable temperature component is generally larger, it is more accurate at this time.

[0031] The operating component can be any component that can drive the components to operate, such as a rotating component (turntable) or a sliding component (a trolley installed on a slide), etc., as long as it can change the position of the temperature sensor, that is, change the object to be measured.

[0032] Further speaking, if Figure 2 As shown, the temperature-changing components installed on the plate surface include a heating component and a cooling component; there is another station in front of the second station, which is the third station 93. When the components are operated to the third station, the temperature sensor can measure the temperature of the temperature-changing component; the temperature-changing component is the opposite of the temperature-changing component of the second station, that is, if the temperature measured at the second station is the heating component, the temperature measured at the third station is the cooling component; if the temperature measured at the second station is the cooling component, the temperature measured at the third station is the heating component.

[0033] The present invention is configured in this way, not only can the verification of the detected data transmission be achieved under the condition of rising temperature, but also the verification of the detected data transmission can be achieved under the condition of cooling, so that the monitoring is more accurate; that is, not only can the accuracy of the temperature sensor detection under the condition of rising temperature be measured, but also the accuracy of the temperature sensor detection under the condition of cooling can be measured. If the result obtained in the detection room is consistent with the temperature change of the variable temperature component in the work station test reached by the running component driving the temperature sensor, it means that the credibility is higher.

[0034] After the detection is completed, the control device returns the temperature sensor to the position for electrical detection.

[0035] Further, the temperature-changing component is a temperature-changing component that changes a certain temperature within a certain period of time, and the temperature change of the temperature-changing component within a certain period of time is a changing parameter. The temperature sensor detects the changing parameter of the temperature-changing component and transmits it to the first signal transceiver device, and the first signal transceiver device transmits this parameter to the second signal transceiver device, and this changing parameter is a test changing parameter; the second signal transceiver device has a pre-input changing parameter of the temperature-changing component under normal conditions, and this changing parameter is a correct changing parameter. The second signal transceiver device can compare the test changing parameter with the correct changing parameter, and output or display the test result.

[0036] For example, the temperature-changing component can increase the temperature by 5°C within 1 minute, the temperature-changing component can increase the temperature by 3°C within 0.5 minutes, the temperature-changing component can decrease the temperature by 5°C within 1 minute, etc.

[0037] The principle of use is that when in use, the temperature of the temperature-changing component is changed through the control device. If the test change parameters received by the second signal transceiver device are the same as the correct temperature change parameters, the correctness of the test can be known; if the test change parameters are different from the correct temperature change parameters, the correctness of the test may be in doubt. On the one hand, it may be a network problem, on the other hand, it may be a problem with the temperature sensor, or a problem with the temperature-changing component, etc., which needs to be verified.

[0038] Furthermore, under the action of the control device, after the above detection is completed, the control device causes the temperature sensor to return to the first position.

[0039] The present invention is set up in this way, not simply to observe whether the monitored data is simply cooled or heated, but to further observe whether the monitored data is consistent when the monitoring system is intact, and this consistency includes the consistency of the data in time and temperature. If these data changes are consistent, it further indicates that the data transmitted by the electrical temperature online monitoring system is reliable.

[0040] The technical solution of the method for online monitoring of electrical temperature of the present invention is implemented as follows: the method for online monitoring of electrical temperature uses a temperature sensor to measure the temperature of the electrical equipment, and transmits the temperature signal measured by the temperature sensor to a remote monitoring room through a network, and a temperature variable component is installed near the electrical component. The temperature variable component is turned on to check whether the temperature signal transmitted by the temperature sensor monitored by the monitoring room changes synchronously. The synchronous change means: if the temperature variable component used is heated, the temperature monitored by the monitoring room is increased, and if the temperature variable component used is cooled, the temperature monitored by the monitoring room is cooled; if the temperature signal of the temperature sensor measured in the monitoring room changes synchronously, it means that the signal transmission is relatively true and reliable, and the credibility is high; if the temperature signal of the temperature sensor measured in the monitoring room does not change synchronously, it means that the signal transmission is relatively untrue and the credibility is low.

[0041] Furthermore, the synchronous change of the temperature signal of the temperature sensor measured in the monitoring room includes two processes, which are the temperature rising process measured by the temperature sensor for the temperature rising component and the temperature falling process measured by the temperature sensor for the temperature falling component.

[0042] Furthermore, the synchronous change also includes whether the temperature signal of the sensor measured in the monitoring room is consistent with the temperature rise value of the preset temperature-changing component within a certain period of time.
