[0022] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Embodiment 1

[0024] Please refer to Figure 1 -11.

[0025] A jumper that realizes the line tracing function through the single - wire protocol provided in this embodiment includes a jumper body 2, a master wiring device 1, a slave wiring device 4, a single - wire 3, a battery, etc. in terms of hardware. It is directly connected between two microcontrollers (MCUs) through the single - wire 3. The digital tube is a modular digital tube, communicates with the master MCU through the I2C protocol and is controlled to display corresponding numbers. The LED lamp uses three groups of LED beads, is directly connected to the master MCU, and the on - off of the LED lamp is directly controlled by the pins of the master MCU. The power supply uses a DCDC power supply of SY8301, with a maximum current of up to 3A, meeting the overall power consumption requirements, and the output voltage is adjustable. The download port uses the SWD download method, and the debugging interface is connected to the master MCU through a serial port for R & D debugging.

[0026] Based on the existing jumper, an additional single - wire 3 is added to connect the microcontrollers (MCUs) in the wiring devices. The entire system is triggered by the buttons integrated in the wiring devices. The mode is determined by the number and duration of button presses. Then, the microcontroller (MCU) sends the data along the single - wire 3 to the receiving end. After the receiving end receives the information, it parses the data and controls the lighting of the lights and the display of the segment - blanking screen according to the corresponding mode.

[0027] The entire process lasts about 1 minute (which can be set by software). Then, the transmitting end and the receiving end of the wiring device enter the sleep state to save energy consumption.

[0028] In the above - mentioned device, the two wiring devices (referring to the master wiring device 1 and the slave wiring device 4) at both ends of the jumper body 2 are connected through the single - wire 3. When the button of the wiring device at end A (referring to the master wiring device 1) is pressed, the wiring device at end A will adjust the high and low levels to the wiring device at end B (referring to the slave wiring device 4) through the single - wire 3 technology (see the following explanation). The data protocol is sent through the change of the high and low levels and the timing of the data transmission signal line. The wiring device at end B receives the data sent by the sending end, determines the lighting method through data parsing and lights up the light - emitting panel. At the same time, it sends a message back to end A. After the wiring device at end A receives the signal transmitted by end B through the data transmission signal line, it synchronously lights up its own light - emitting panel. After a certain period of time, both sides go out at the same time and wait for the button to be pressed next time.

[0029] When the wiring device at one end is pressed, the internal MCU judges and classifies by arranging the number and time of pressing, and sends it to the other end through the data transmission signal line (referring to the single - wire 3). Both ends light up the corresponding classified colors and frequencies at the same time.

[0030] The working principle is as follows: The MCUs at both ends of the jumper are connected through the SingleLine wire parallel to the jumper. The programs in the two MCUs (referring to the host MCU control module of the main control wiring device 1 and the slave MCU control module of the slave control wiring device) communicate through the single bus 3. The slave MCU analyzes the protocol of the host MCU and controls the corresponding LED to light up, and the digital tube (referring to the segment display) displays the corresponding number.

[0052] One-wire protocol (example): The normal state of the data transmission signal line is low level.
