DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 , 2As shown in , 3, 4, and 5, the electrical temperature online monitoring system includes a distribution room 11 and a monitoring room 12, wherein the distribution room has an electrical 2, and a temperature sensor 5 for measuring the electrical temperature is also installed in the distribution room, the temperature sensor is connected to a signal converter, and the signal converter is connected to a first signal transceiver 13, the signal converter can convert the temperature signal measured and transmitted by the temperature sensor into an electrical signal, and send it through the first signal transceiver, the monitoring room has a second signal transceiver 14, the first signal transceiver and the second signal transceiver match and are connected through a network; its characteristics are: the electrical 2 is installed on the board surface 3, and there is also a rotating shaft 41 driven by a motor 4 on the board surface, the rotating shaft has a rotating rod 42, and the temperature sensor 5 is installed on the other end of the rotating rod; and there is also a control The device is connected to the motor and controls the rotation of the rotating shaft. It also includes a temperature-changing component 6, which is connected to the control device; the side of the temperature-changing component is provided with a toggle slot 61, and the temperature sensor is provided with a toggle block 51, and the toggle block cooperates with the toggle slot. When the temperature sensor is running, the temperature sensor drives the temperature-changing component to run through the cooperation of the toggle block and the toggle slot; under the action of the control device, the temperature sensor can be in multiple positions, one of which is the first position 71. At the first position, the temperature-changing component is in electrical contact, and the temperature-changing component is also in contact with the temperature sensor; one of the positions is the second position 72. At the second position, the temperature-changing component is in contact with the temperature sensor, and the temperature-changing component is not in electrical contact; a spring 81 is also installed on the plate surface to return the temperature-changing component to the first position.

[0027] Principle of use: The present invention is configured such that when the temperature sensor is in the first station, it obtains an electrical temperature test data. However, at this time, the reliability of this data is unknown. The second signal transceiver device can be operated to change the position of the temperature sensor through the first signal transceiver device and the motor. Since the temperature-changing component has a toggle slot on the side, the temperature sensor has a toggle card block, and the toggle card block cooperates with the toggle slot. When the temperature sensor is running, the temperature sensor drives the temperature-changing component to operate through the cooperation of the toggle card block and the toggle card slot. At this time, the temperature-changing component does not contact the electrical appliance at all, and the temperature change of the temperature-changing component is not affected by the electrical appliance and is easy to change temperature. That is, the temperature sensor can more easily test the changed temperature, and a higher sensitivity effect can be achieved. Since the present invention adopts the method of verifying the accuracy of the online detection system by changing the temperature, the purpose of knowing the degree of accuracy can be achieved.

[0028] In one embodiment, the plate surface has an arc-shaped slideway 82, and the temperature sensor and the temperature-changing component are installed on the slideway, and the temperature sensor operates in the slideway. The present invention has the advantage of more stable operation.

[0029] Furthermore, the electrical components, temperature-changing components, and temperature sensor sides are provided with magnets 83 .

[0030] The present invention is configured in this way, and when the temperature variable component is in the first working position, the electrical, temperature variable component and temperature sensor are better combined, that is, they form an integral body. When the temperature sensor is running, it can ensure that the temperature variable component is attached to the temperature sensor, that is, "bonded" together.

[0031] Furthermore, the temperature-changing component includes a temperature-raising component 62 and a temperature-lowering component 63, the temperature-raising component and the temperature-lowering component are opposite temperature-changing components, the second workstation includes a front second workstation 721 located in front of the first workstation and a rear second workstation 722 located behind the first workstation, the temperature-raising component and the temperature-lowering component are respectively installed on the front and rear sides of the first workstation, and the temperature-changing component running to the front second workstation and the temperature-changing component running to the rear second workstation are opposite temperature-changing components.

[0032] The present invention is configured in this way, so that it can not only realize detection under the condition of rising temperature, but also realize detection under the condition of falling temperature, so that the detection data is more comprehensive.

[0033] Furthermore, the electrical side also has a stirring convexity 21 to prevent the temperature-changing component from exceeding, and the stirring convexity is located between the temperature-raising component and the temperature-lowering component.

[0034] The present invention is arranged in this way to ensure that the temperature-changing component is in the correct position on the electrical side, that is, "does not cross the line".

[0035] Furthermore, under the control of the control device, the temperature sensor moves forward to the front second station, stays for a period of time, and then returns to the first station, and then the temperature sensor moves backward to the rear second station.

[0036] The present invention is arranged in this way, and also has the advantage of a higher degree of automation.

[0037] 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 the detected 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 the correct changing parameter. The second signal transceiver device can compare the detected changing parameter with the correct changing parameter, and output or display the comparison result.

[0038] 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.

[0039] 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.

[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. When the electrical temperature is monitored online, in order to know the reliability of the detection data, a temperature sensor is used to detect a temperature-changing component for verification to check whether the temperature signal transmitted by the temperature sensor to the monitoring room for monitoring 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; and the detection of this temperature change is a temperature change detection performed after the temperature change component is separated from the electrical equipment.

[0041] Furthermore, the temperature change detection includes temperature rise detection and temperature drop detection.

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

[0043] Furthermore, the temperature change is detected using the above-mentioned electrical temperature online monitoring system.
