[0093] At this time, in the working state of the electronic product, the workflow of the electronic product is traversed, and the corresponding communication part is determined according to the workflow of the electronic product. The communication part is introduced, and the communication interface of the electronic product is located based on the communication part, so as to control the communication interface of the electronic product. Therefore, the communication interface is fixed, and the communication detection is triggered based on the communication interface; in the communication detection of the communication interface, the communication data received by the communication path of the communication interface is collected, and the communication path is further controlled. Reference Figure 3 , in step S12, a plurality of sub-communication paths are determined based on the division of the communication path, and the communication data received by each sub-communication path is marked;

[0102] In an embodiment of the present application, a communication path is frozen, and a traversal is performed on the communication path to facilitate traversal of the communication path, and multiple branch points are determined in the traversal of the communication path. The multiple branch points are controlled to facilitate determination of a division pattern based on the multiple branch points and the corresponding communication objects, thereby performing multi-dimensional control based on the multiple branch points and the corresponding communication objects, ensuring the accuracy of the division pattern, and facilitating further division of the communication path.

[0103] At this time, the partitioning mode and the communication path are associated; multiple sub-communication paths are determined based on the communication path and the partitioning mode, and the multiple sub-communication paths are controlled, thereby ensuring multi-dimensional management and control of the multiple sub-communication paths.

[0104] Therefore, multiple sub-communication paths are fixed, and corresponding receiving channels are matched based on the multiple sub-communication paths; communication data received by the corresponding sub-communication paths are presented along each receiving channel; the communication data is marked, and the communication data is further processed.

At this time, the multiple temperature parameters are distributed at different positions of the communication interface, and the temperature of the communication interface is presented through multiple temperature parameters.

[0133] At this time, the locations of multiple temperature parameters are collected, so as to determine the two adjacent temperature parameters for the locations of the multiple temperature parameters, thereby determining the corresponding temperature change based on the two adjacent temperature parameters, introducing multiple temperature change, and further controlling the multiple temperature change. Therefore, multiple temperature change are collected, and the temperature abnormality location is determined according to the multiple temperature change and the location of the multiple temperature parameters; the corresponding temperature abnormal part is determined based on the positioning detection of the temperature abnormal location; multiple temperature abnormal parts are collected, and the models of multiple temperature abnormal parts and communication interfaces are associated; the corresponding second abnormal event is matched according to the models of multiple temperature abnormal parts and communication interfaces, so as to control the abnormalities at the temperature level. At the same time, it is compatible with the overall consideration of the models of multiple temperature abnormal parts and communication interfaces, and the second abnormal event is controlled in multiple dimensions to ensure the accuracy of the second abnormal event.

At the same time, real-time protection is performed on the communication interface.

[0162] See also Fig.10 , Fig.10 It is a circuit diagram of a protection circuit of a communication interface of an electronic product in an embodiment of the present invention.

[0163] The protection circuit of the communication interface of the electronic product includes: a control unit U23, several first pins of the control unit U23 are electrically connected to the communication IO port GPIO; a voltage regulator diode ZD, the cathode of the voltage regulator diode ZD is electrically connected to several second pins of the control unit U23; a universal diode D, the anode of the universal diode D is electrically connected to several second pins of the control unit U23; a resettable fuse PTC, the first end of the resettable fuse PTC is electrically connected to several second pins of the control unit U23; a resistor R, the first end of the resistor R is electrically connected to the second end of the resettable fuse PTC; an output port OUTPUT, the output port OUTPUT is electrically connected to the second end of the resistor R.

[0164] The control unit U23 can be an MCU, a digital logic gate, an FPGA, etc. In this embodiment, the number of the voltage stabilizing diode ZD, the general diode D, the self-recovery fuse PTC, and the resistor R are four respectively, thereby forming 4 channel protections.

[0165] In the protection circuit embodiment of the present invention, during normal communication, the communication IO port GPIO sends a signal to the control unit U23, which is output to the output port OUTPUT after passing through the control unit U23, and then connected to the device port that needs to communicate through the connector. When the output port OUTPUT is mistakenly connected or accidentally connected to a voltage greater than 5V, it will first be limited by the resistor R and the self-resetting fuse PTC, and then stabilized by the voltage-stabilizing diode ZD. At the same time, it will also be clamped by the universal diode D, so as to limit the voltage of the communication IO port GPIO to the withstand voltage range of the control unit U23 itself, so as to facilitate the control of abnormalities at the current level and prevent current and temperature abnormalities, thereby protecting the control unit U23 from being damaged by excessive voltage or temperature.

[0166] Therefore, in current electronic products, especially thermal printers, portable printers, label printers and other products, when the DC withstand voltage of the external communication interface is basically around 0V-5V, there is a high probability that a voltage higher than 5V will be mistakenly introduced into the corresponding interface during manual wiring, thereby burning the product or device motherboard. The above embodiment can prevent the communication interface from burning the motherboard when a voltage exceeding the chip's own withstand voltage (usually 5V) is introduced to the communication line. In particular, the communication interface can increase the DC voltage limit of all signal ports to more than 24V or withstand voltage of more than 48V without affecting normal signal transmission, which can prevent personnel from mistakenly connecting a voltage of more than 24V to the communication line and burning the equipment. It can also have ESD protection, surge protection, overcurrent protection, overvoltage protection, short circuit protection and other functions at the same time, and can well protect the key chip on the motherboard from damage. It can be seen that the control unit U23 can be a key chip. Different withstand voltage protection levels can be achieved by selecting the resistance value of the resistor R (usually 22-1000Ω) according to the communication speed and selecting resistors of different powers (usually greater than 1W) according to the protection current.
