Detailed Description
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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, an operator can only check a plurality of wires in a cable one by means of a multimeter, specifically, as shown in fig. 1, a negative electrode of the multimeter is grounded or connected with one end of an auxiliary wire, and a positive electrode of the multimeter is connected with one end of one wire of the cable to be detected, and the wire is used as a signal source, namely, a gear of the wire is placed in a resistance detection gear to enable the wire to output a current signal; and a universal meter is also needed at the other end of the cable, the universal meter is placed in a current gear or a voltage gear, the negative electrode of the universal meter is grounded or one end of the auxiliary connecting wire is connected, the positive electrodes of the universal meter are connected with the conducting wires of the cable one by one, and when an electric signal is detected, the conducting wire can be determined to be the same as the conducting wire connected with the positive electrode of the previous universal meter.
As can be seen from the above description, the method has extremely low line calibration efficiency, and the following embodiments are proposed to improve the line calibration efficiency.
Example one
Fig. 2 is a schematic diagram of a cable calibration device according to an embodiment of the present application.
As shown in fig. 2, the cable calibration apparatus provided in this embodiment includes a signal generating device 10 and a signal detecting device 20, which are respectively disposed at the head and tail ends of a cable 100 to be tested, where the head and tail are relative concepts. The signal generating equipment is connected with the head end of the cable to be detected, and the signal detecting equipment is connected with 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 of which is connected to one of the conductors 101 of the cable to be tested, as shown in fig. 4. The signal detection device is provided with a plurality of signal input terminals 21, each for connecting to one conductor of the other end of the cable to be detected, as shown in fig. 5.
A first ground terminal 12 is provided on the signal generating device, and a second ground terminal 22 is provided on the signal detection device. The first ground is used for grounding or connection to the auxiliary line 200, and the second ground is also used for grounding or connection to the auxiliary line 200, so that the respective wires become part of the loop through the ground or the auxiliary line.
In order to facilitate connection, the signal output terminal and the signal input terminal both adopt a pressure spring structure, and specifically, as shown in fig. 6, one end of a lead is pressed by a pressure spring 300, so that connection is facilitated on one hand, and electric connection is firmer by the pressure spring.
After the connection is completed, when the verification is executed, each signal output terminal can output a verification signal to one end of the corresponding wire, and the signal detection equipment receives the corresponding signal through the signal input terminal and then displays the signal output terminal corresponding to the signal input terminal through the display interface of the signal detection equipment, so that an operator can conveniently find the head end and the tail end of each wire to obtain a 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 equipment is provided with an approximate position digital label, each cable circulation loop trigger pulse signal triggers pulses according to different time, and the signal detection device can be determined to judge and correct the cable position according to the difference of the receiving time of the trigger pulse signals because the current of the conducted cable loop can not flow to other cable loops. In addition, the signal detection equipment registers data codes through the single chip microcomputer, and digital labels at corresponding positions of the interfaces are displayed in the interface display disc, so that simultaneous line calibration of a plurality of cables is realized.
In addition, as shown in fig. 7, the signal detection device is built based on a single chip microcomputer, and at least includes a register circuit 901, an adder circuit 902, and a display circuit 903.
Specifically, in order to prevent the non-conducted cable loop from influencing the calibration position of the normally-conducted cable loop, the adder performs bit-adding calculation, even if the individual cable loop is not conducted, the adder starts calculation by receiving the first pulse, cannot receive the signal of the individual cable loop in time, and performs bit-adding calculation, so that the condition that the cable is not misplaced in the line calibration process is guaranteed.
Further, the width of the square wave signal is determined according to the number of the line calibration cables connected to the signal source generating device. The pulse time control of each cable loop can be realized by setting the width of the square wave; if the width of the square wave signal is 100ms and 20 cable connection ports are arranged, the pulse duration current time output by the cable loop signal source is not less than 5ms every day. According to the duration of the current measured by the ammeter, the on-off condition of the wiring can be determined and judged, and the square wave signal is shown in fig. 8.
According to the technical scheme, the cable calibration device provided by the embodiment comprises the signal generating equipment and the signal detecting equipment. The signal generating equipment is connected with one end of the cable to be checked and is provided with a plurality of signal output wiring terminals, each signal output wiring terminal is used for connecting one conducting wire of the cable to be checked, and the signal output end is used for outputting a checking signal; the signal detection equipment is connected with the other end of the cable to be detected and is provided with a plurality of signal input wiring terminals, each signal input wiring terminal is used for being connected with one conducting wire of the cable to be corrected, and the signal detection equipment is used for displaying a checking result based on the checking signal. Through the device, the calibration of a plurality of wires can be realized simultaneously without a universal meter, so that the calibration efficiency is improved.
