The charging plug 30 is used to connect to a power adapter, and the charging port 40 is used to connect to a charging device.

[0040] Continuing to observe, it can be seen that the data line 10 includes a plurality of cores 11, each core 11 includes a power core 111 and a data transmission core 112, the power core 111 is used to transmit voltage and current, and the data transmission core 112 is used to transmit signals.

[0041] Continuing to observe, we can see that the data line protection module 20 is a small electronic device, which can be installed in the middle part of the data line 10 through a detachable interface. The circuit board of the data line protection module 20 integrates various functional units such as the information acquisition unit 21, the data analysis unit 22, the display unit 23 and the adjustment unit 24.

[0042] The information collection unit 21 is a temperature sensor, which can collect the state parameters of each wire core 11 in real time and send them to the data analysis unit 22 for analysis through the data transmission wire core 112. The state parameters include the temperature T of the single wire core 11 at one end of the charging plug 30. 1i , and the output temperature T at one end of the data line protection module 20 1q , the temperature difference between the two ends of a single core 11 is ∆T1=T 1i -T 1q, the average temperature is T x , and T 1i The data is transmitted through the data transmission core 112 in the data line 10.

[0043] The state parameters also include the current value and voltage value flowing through a single core 11, which are marked as i1, u1...in, un, respectively, to calculate the average current I of multiple cores 11. p , average voltage U p .

[0044] Among them, the data analysis unit 22 is a microprocessor, which can analyze and judge the received status parameters according to preset thresholds and formulas, and send the analysis results to the display unit 23 and the adjustment unit 24. The data analysis unit 22 is used to determine whether the temperature of the charging plug 30 is abnormal. If T1>5, it is determined that the temperature of the charging plug 30 is abnormal. If T1<5, it continues to determine whether the current transmission temperature is abnormal.

[0045] The data analysis unit 22 calculates the instantaneous parameter X of the data line 10 according to each temperature fluctuation frequency. X , and the instantaneous parameter X of the single core wire 11 is obtained X Compared with the threshold, if X X If X is less than the threshold, the data line 10 operates normally.
