Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

At present, the operator can only rely on the multimeter to verify the multiple wires in the cable one by one. As shown in Figure 1, the negative electrode of the multimeter is grounded or connected to one end of the auxiliary line, and the positive electrode is connected to one of the cables to be tested. Connect one end of the wire and use it as a signal source, that is, put its position in the resistance detection block, so that it outputs a current signal; at the other end of the cable, a multimeter is also needed, put it in the current file or voltage file, and connect it to the negative pole Connect one end of the grounding or auxiliary wire, and connect the positive pole to the wire of the cable one by one. When an electrical signal is detected, it can be determined that the wire and the wire connected to the positive pole of the previous multimeter are the same wire.

It can be seen from the above description that the alignment efficiency of this method is extremely low. In order to improve the alignment efficiency, the following embodiments are proposed.

Example 1

FIG. 2 is a schematic diagram of a cable alignment device according to an embodiment of the present application.

As shown in FIG. 2 , the cable alignment device provided in this embodiment includes a signal generation device 10 and a signal detection device 20 , which are respectively arranged at the head and tail ends of the cable 100 to be tested. Of course, the head and tail here are relative concepts. The signal generating device is connected to the head end of the cable to be detected, and the signal detection device is connected to the tail end of the cable to be detected.

The signal generating device is provided with a plurality of signal output terminals 11 , as shown in FIG. 3 , each signal output terminal is connected to a wire 101 of the cable to be detected, as shown in FIG. 4 . The signal detection device is provided with a plurality of signal input terminals 21 , as shown in FIG. 5 , each signal input terminal is used to connect a wire of the other end of the cable to be detected.

Furthermore, a first ground terminal 12 is set on the signal generating device, and a second ground terminal 22 is set on the signal detection device. The first ground terminal is used for grounding or connection with the auxiliary line 200, and the second ground terminal is also used for grounding or connection with the auxiliary line 200, so that each wire becomes a part of the loop through the ground or the auxiliary line.

In order to facilitate the connection, the above-mentioned signal output terminals and signal input terminals all adopt the compression spring structure. Specifically, as shown in Figure 6, a compression spring 300 is used to press one end of the wire. On the one hand, the connection is convenient, and the compression spring Make the electrical connection stronger.

After completing the above connections, when performing the verification, each signal output terminal will output a verification signal to one end of the corresponding wire, and the signal detection device will display the signal through its display interface after receiving the corresponding signal through its signal input terminal. The input terminal corresponds to the signal output terminal, so that the operator can easily find the head and tail of a single wire and obtain the verification result.

The verification signal is a trigger pulse signal, specifically a square wave signal, a step signal or a level signal.

Specifically, the signal output terminal on the signal generating device has a predetermined position digital label. The trigger pulse signal of each cable circulation loop is triggered according to different times. Since the current of the conducting cable loop will not flow to other cable loops, the trigger pulse signal will be eliminated. The difference in receiving time can determine the position of the calibration cable by the signal detection device. In addition, the signal detection device registers the data code through the single-chip microcomputer, and displays the digital label of the corresponding position of the interface in the interface display panel, so as to realize the alignment of multiple cables at the same time.

In addition, as shown in FIG. 7 , the signal detection device is constructed based on a single-chip microcomputer, and includes at least a register circuit 901 , an adder circuit 902 and a display circuit 903 .

Specifically, in order to prevent the non-conducted cable loop from affecting the calibration position of the normally-conducted cable loop, the adder is used to supplement the calculation. Even if there are individual cable loops that are not turned on, the adder starts the calculation by receiving the first pulse, and timely If the individual cable loop signal is not received, the adder performs the complement calculation to ensure that the cable will not be misaligned during the alignment process.

Further, the width of the square wave signal is determined according to the number of calibration cables connected to the signal source generating device. That is, by setting the width of the square wave, the pulse time control of each cable loop can be realized; if the width of the square wave signal is 100ms, and 20 cable connection ports are set, the continuous current time of the output pulse of the cable loop signal source is not less than 5ms every day. . According to the current duration measured by the ammeter, the on-off condition of the wiring can be determined. The square wave signal is shown in Figure 8.

It can be seen from the above technical solutions that this embodiment provides a cable alignment device, which includes a signal generating device and a signal detecting device. The signal generating device is connected to one end of the cable to be tested, and it is provided with a plurality of signal output terminals, each signal output terminal is used to connect a wire of the cable to be calibrated, and the signal output end is used to output the calibration signal; signal detection The device is connected to the other end of the cable to be tested, and it is provided with a plurality of signal input terminals, each signal input terminal is used to connect a wire of the cable to be calibrated, and the signal detection device is used to display the calibration result based on the calibration signal . Through the above device, the calibration of multiple wires can be realized at the same time without a multimeter, thereby improving the calibration efficiency.
