Description

Technical Field

[0001] This utility model relates to the field of jumper technology, and in particular to a jumper that implements a wire-finding function through a single-bus protocol. Background Technology

[0002] Modern computer rooms, data centers, and structured cabling projects require connections from a large number of wire harnesses. In the event of a fault or maintenance, how to quickly locate the end interface of the wire harness has always been a research topic. Currently, the market achieves the wire finding function by integrating twisted-pair cables or special optical fibers inside the wire harnesses such as network cables and optical fibers. However, this can only find a single wire. When multiple wires are triggered at the same time, it is difficult to distinguish them and manual differentiation is required.

[0003] This patent proposes a novel jumper that integrates a single internal wire to achieve a wire-finding function. By varying the number of button presses, an intelligent module is used to differentiate the light color, the number of times the light is turned on, and the broken code screen, thereby enabling a rapid wire-finding function that triggers multiple wires simultaneously. Utility Model Content

[0004] The purpose of this invention is to provide a jumper that implements wire finding function through a single bus protocol, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a jumper that implements a line-finding function via a single-bus protocol, characterized in that it consists of a master control wiring device, a jumper body, and a slave control wiring device; the master control wiring device includes a power supply, a master control MCU, a digital tube, LEDs, a download interface, and a debugging interface; the digital tube adopts a modular design, communicates with the master control MCU via the I2C protocol, and is controlled to display corresponding numbers; the LEDs use three sets of LED beads, are directly connected to the master control MCU, and are directly controlled by the pins of the master control MCU to turn on and off; the download interface adopts the SWD download method; the debugging interface adopts a serial port and is connected to the master control MCU; the slave control wiring device includes a power supply and a slave control MCU, and the slave control MCU is electrically connected to the master control MCU via a single bus.

[0006] Compared with the prior art, the advantages of this utility model are: the line-finding function is realized by integrating a single wire internally, and the rapid line-finding function is realized by using an intelligent module to differentiate the light color, the number of times the button is pressed, and the broken code screen by different numbers of times.

[0007] As an improvement of this utility model, the power supply adopts a DC power supply with adjustable output voltage. The purpose of this design is to ensure that the output voltage is very stable, the output ripple is reduced, and the accuracy is high, thereby ensuring the normal operation of the equipment and the accuracy of the measurement results.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example 1

[0023] Please refer to Figure 1 -10.

[0024] This embodiment provides a jumper that implements a wire-finding function via a single-bus protocol. Its hardware includes a jumper body 2, a master control wiring device 1, a slave control wiring device 4, a single bus 3, a battery, etc., directly connecting two microcontrollers (MCUs) via a three-phase single bus. The digital tube uses a modular design, communicating with the master MCU via the I2C protocol and being controlled to display corresponding numbers. Three sets of LEDs are directly connected to the master MCU and controlled by its pins to turn on and off. The power supply uses a SY8301 DC-DC power supply with a maximum current of 3A, meeting overall power consumption requirements, and the output voltage is adjustable. The download port uses the SWD download method, and the debugging interface uses a serial port connected to the master MCU for research and development debugging.

[0025] Based on the existing jumper, a single bus 3 is added to connect to the microcontroller (MCU) in the wiring device. The entire system is triggered by a button integrated in the wiring device. The mode is determined by the number of button presses and the duration. The microcontroller (MCU) then sends the data to the receiving end along the single bus 3. After receiving the information, the receiving end parses the data and controls the lights to turn on and the broken code display to be displayed according to the corresponding mode.

[0026] The entire process lasts about 1 minute (which can be set via software), after which the transmitter and receiver of the wiring device enter a sleep state to save energy.

[0027] In the above device, two wiring devices (referring to the master control wiring device 1 and the slave control wiring device 4) at both ends of the jumper body 2 are connected via a single bus 3. When the button of the wiring device at end A (referring to the master control 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 control wiring device 4) through the single bus 3 technology (see the explanation below). The data protocol is transmitted through the high and low level changes and timing of the data transmission signal line. The wiring device at end B receives the data sent by the sending end, determines the lighting mode through data parsing, and lights up the light-emitting board. At the same time, it replies to end A. After receiving the signal transmitted by end B through the data transmission signal line, the wiring device at end A synchronously lights up its own light-emitting board. After a certain period of time, both lights go out at the same time, waiting for the button to be pressed again.

[0028] When the wiring device at one end is pressed down, the internal MCU judges and classifies the device by arranging the number of times and the time of pressing down, and sends the data transmission signal to the other end through the data transmission signal line (referring to single bus 3). At the same time, the corresponding colors and frequencies of the two ends light up.

[0029] The working principle is as follows: The MCUs at both ends of the jumper are connected via a SingleLine line parallel to the jumper. The programs within the two MCUs (referring to the master MCU control module of the master control wiring device 1 and the slave MCU control module of the slave control wiring device) communicate via a single bus 3. The slave MCU parses the protocol of the master MCU and controls the corresponding LED to light up, and the digital tube (referring to the code break display) displays the corresponding number. The specific lighting method and the numbers displayed on the code break display are shown in Table 1 below.

[0053] Single-bus protocol (example): The data transmission signal line is normally low.

The data bit duration is greater than 72µs. When the device has received more than 2 bits of data, or when the level is low for more than 580µs, the transmission is interrupted.
