[0045] As attached Figure 1 , Attachment Figure 2 and attached Figure 4 As shown, in an illustrative embodiment of a temperature rise data acquisition system of the present invention, the temperature rise data acquisition system is used to acquire the temperature of the object to be acquired. Temperature sensors are set on multiple devices inside the object to be acquired 1.

[0046] The temperature rise data acquisition system includes a temperature sensor integrated line 2, a wiring harness integrator 3, a data transmission line 7, a temperature rise tester 4 and a PC terminal 6.

[0050] The temperature rise tester 4 is connected to the second plug-in 72 of the data transmission line 7 , and a plurality of channels are provided at the connection between the temperature rise tester 4 and the second plug-in 72 .

[0051] The PC terminal 6 is connected to the temperature rise tester 4 .

[0052] Among them, the collected object 1 includes a transformer or a reactor, and the locations where the temperature sensor is set include but are not limited to: multi-phase inner winding, multi-phase outer winding, multi-phase winding surface, upper and lower surface iron cores, inside the transformer or reactor box and outside the transformer or reactor box.

[0053] The wiring harness integrator 3 and the first and second plug-ins 71 and 72 of the data transmission line 7 integrate the transmission lines, facilitating the connection and installation of various components in the system. The temperature rise tester 4 detects the temperature data of each component in the object 1 and transmits it to the PC 6 for data visualization.

[0054] In some embodiments, as shown in the attached Figure 2 and attached Figure 3 As shown, the harness integrator 3 further includes a ground terminal 31 , which is grounded.

[0055] The ground terminal 31 guides out interference signals in the data transmitted by the harness integrator 3 , thereby improving data stability and accuracy and facilitating subsequent data processing by the PC terminal 6 .

[0056] In some embodiments, as shown in the attached Figure 5 As shown, a wire harness shielding layer and an insulating protective layer are provided on the outside of the connecting wire in the data transmission line 7 , and the wire harness shielding layer is introduced into the ground terminal 31 .

[0057] The wiring harness shielding layer is connected to the ground terminal 31 to conduct interference signals. The wiring harness shielding layer is provided to further improve the circuit's ability to resist electromagnetic interference when collecting temperature data at high speed.

[0058] In some embodiments, as shown in the attached Figure 1 As shown, the temperature rise tester 4 is provided with multiple slaves, the PC end 6 is provided as a host, and the multiple slaves are connected to the host respectively.

[0059] The temperature rise tester 4 is provided with multiple slaves for data transmission, which on the one hand expands the data transmission channel and on the other hand speeds up the transmission speed and improves the data processing capability.

[0060] In some embodiments, as shown in the attached Figure 6 and attached Figure 7 As shown, the temperature rise data acquisition system also includes:

[0061] The alarm component includes a thermal probe 8, an intermediate relay 9 and a buzzer 10. The thermal probe 8 is set on multiple devices of the collected object 1. The thermal probe 8 is connected to the intermediate relay 9 and the PC terminal 6 respectively, and the buzzer 10 is connected to the intermediate relay 9.

[0062] An alarm component is set up to respond to abnormal temperature in the first time. The alarm component is connected to the PC terminal 6 and can transmit data to the PC terminal 6 for further analysis.

[0063] In some embodiments, a channel of the data input end, a channel of the data output end, a channel of the data input interface, a channel of the data output interface, a channel in the first plug-in 71, and a channel in the second plug-in 72 are correspondingly connected to a channel of the temperature rise tester 4.

[0064] The corresponding channels are connected to facilitate data transmission and reduce confusion caused by data during transmission.

[0065] In some embodiments, as shown in the attached Figure 1 As shown, the temperature rise data acquisition system further includes a USB converter 5, one end of which is connected to the temperature rise tester 4. A PC terminal 6 is connected to the other end of the USB converter 5.

[0066] The USB converter 5 is arranged in the path for the PC terminal 6 to receive data, thereby improving the communication compatibility.

[0067] In practical applications, when connecting temperature sensors, the temperature sensor integrated cable 2 is grouped into four channels, with each cable group protected by a wire shield and insulation layer. This improves immunity to electromagnetic interference and reduces the risk of interference signals being mistakenly collected into the system due to excessive sampling frequency. Improved and integrated temperature sensor integrated cables significantly shorten installation time, reducing the time required to set up and connect temperature sensors from at least 30 minutes to just 5 minutes.

[0068] In the temperature rise data acquisition system, each set of temperature sensor integrated wires 2 and data transmission wires 7 are wrapped with a wire harness shielding layer and an insulating protective layer to improve the ability to resist electromagnetic interference and reduce the situation where interference signals are mistakenly collected into the system due to excessive sampling frequency.

[0069] The test structure of the Temperature Rise Tester 4 has been optimized, expanding the original 8-channel Temperature Rise Tester 4 to 16 channels. The additional channels enable more comprehensive monitoring of the details of the product under test, facilitating a more systematic understanding of the product's test performance. This solves the problem of limited data collection due to a limited number of acquisition channels, which can't meet more testing needs.

[0070] The first plug-in 71 and the second plug-in 72 of the data transmission line 7 are respectively provided with eight channels. Both data transmission lines are connected to the temperature rise tester and the harness integrator to transmit temperature data together.

[0071] The temperature rise tester 4 uses the RS48 handshake protocol to form a master and slave measurement and control network, switching from a single-slave mode to a multi-slave mode. These multiple slaves include a first slave 41 and a second slave 42. The PC 6 is set as the master, with the first slave 41 being the original module of the temperature tester and the second slave 42 being a new expansion module. Using a master-slave communication mode, the system expands from the original 8 channels to 16.

[0072] Since PC 6 is mostly a USB interface, a USB converter 5 is provided to improve communication compatibility, enabling RS485 serial port to USB conversion. The existing temperature rise tester 4 is adapted to RS485 communication technology, enabling communication between the temperature rise tester 4 and the host computer of PC 6, transmitting data to the custom software of PC 6, thus completing the hardware setup for realizing various functions.

[0073] In order to better monitor the operation of the product, an alarm component is set in the temperature rise data acquisition system to ensure that the fault problem is fed back to the test personnel as soon as possible. The alarm information will also be recorded on the PC through communication6 for further analysis.

[0074] The alarm component includes a thermal probe 8, an intermediate relay 9, a buzzer 10 and a power supply 11. The thermal probe 8, the intermediate relay 9, the buzzer 10 and the power supply 11 are connected by wires to form an alarm circuit.

[0075] The thermal probe 8 is set at the monitoring point inside the collected object 1. The thermal probe 8 is conductive to the preset temperature. When the monitoring point reaches the preset temperature, the alarm circuit will be conductive, and the buzzer 10 will sound an alarm.

[0076] Through the description of multiple embodiments of the temperature rise data acquisition system of the present invention, it can be seen that the embodiments of the temperature rise data acquisition system of the present invention have at least one or more of the following advantages:

[0077] 1. The temperature rise data acquisition system is equipped with multi-channel transmission to improve data transmission efficiency. After connecting to the PC, the temperature rise data acquisition system can automatically collect and store data.
