Abstract
Claims
1. A real-time online temperature measuring device, characterized in that, It includes a housing, a connecting post protruding upward from the upper end face of the housing, and a contact exposed on the upper end face of the connecting post; The contact is led out from the housing, passes through the connecting post and is exposed, and comes into contact with the copper busbar in the busbar connector to draw power and monitor temperature. The side of the connecting post is provided with a plurality of connecting protrusions, which are adapted to the connecting grooves in the busbar connector. The connecting protrusions enter the connecting grooves to realize the installation of the connecting post in the busbar connector. The housing contains a data processing unit, a data transmission module, and a power acquisition module; the power acquisition module obtains electrical energy through the contacts and converts it into power for the adapter; the data processing unit processes the temperature signals collected by the contacts; and the data transmission module sends the temperature data to the background monitoring system.
2. The real-time online temperature measuring device according to claim 1, characterized in that, The contact includes a power-collecting contact and a temperature-measuring probe, both integrated on the same conductive substrate. 3.The real-time online temperature measuring device according to claim 1, characterized in that, The upper end face of the housing is provided with limiting blocks extending to both sides along the extension direction of the busbar groove. After the limiting blocks enter the busbar groove connector, they are fixed by bolts.
4. The real-time online temperature measuring device according to claim 1, characterized in that, The data processing unit includes a signal conversion circuit and a threshold comparison unit; the signal conversion circuit receives the original temperature analog signal collected by the contact and converts it into a digital signal; the threshold comparison unit compares the temperature data with a preset safe temperature threshold range, generates a temperature warning signal when the temperature data reaches the upper limit of the threshold warning, and generates a temperature alarm signal when the temperature data exceeds the upper limit of the threshold alarm.
5. The real-time online temperature measuring device according to claim 1, characterized in that, The power supply module includes a rectifier circuit, a filter circuit, a voltage regulator circuit, a voltage conversion circuit, and an overvoltage and overcurrent protection unit connected in sequence. The rectifier circuit is connected to the contacts and converts the AC power from the bus to DC power. The filter circuit filters out DC ripple. The voltage regulator circuit stabilizes the DC voltage within a reference range. The voltage conversion circuit converts the reference voltage into different levels of DC voltage adapted to the data processing unit and the data transmission module. The overvoltage and overcurrent protection unit monitors the output voltage of the voltage regulator circuit and the output current of the voltage conversion circuit, and cuts off the output or adjusts the parameters when abnormalities occur to protect subsequent modules.
6. The real-time online temperature measuring device according to claim 4, characterized in that, The data transmission module adopts LoRa wireless communication technology and has a built-in data encryption unit and power consumption control unit. The data encryption unit encrypts the transmitted temperature data, warning and alarm signals. The power consumption control unit works in conjunction with the data processing unit. When the temperature data is within the safe temperature threshold range, the control module enters a low-power mode and uploads data every 1-5 minutes. When the temperature is abnormal, it switches to a real-time upload mode.
7. The real-time online temperature measuring device according to claim 6, characterized in that, The housing has a data transmission port on its side, which is electrically connected to the data transmission module and connected to an external device via a data cable to enable local export of temperature data or wired debugging of the device. 8.The real-time online temperature measuring device according to claim 1, characterized in that, An opening is provided on the side of the housing, and an openable cover is provided at the opening; one side of the cover is rotatably connected to the housing by a hinge, and the other side is fixedly connected to the housing by bolts.
