Description

Cable dedicated liner

technical field

The invention relates to a cable alignment device, in particular to a special cable alignment device suitable for the wiring debugging construction of secondary equipment in substations.

Background technique

In modern machine tools, electrical instruments and various automatic control devices, more and more control components are connected through multi-core cables. The correctness and reliability of multi-core cables and their connecting plugs play an important role in ensuring the entire electrical control system Played a vital role in reliable operation. Therefore, the inspection of finished cables has become an indispensable link in the cable assembly and production process. In order to ensure the reliable use of the cable, it is generally required to be strictly inspected before use, so that unqualified products can be found and eliminated in time. At present, the cable detection of most domestic production plants adopts the traditional and backward manual detection method, using a multimeter, buzzer or indicator light to manually overlap point by point to judge the continuity of each connecting line.

In the power system, usually in the power construction or in the power test debugging, the multimeter is used to calibrate the line. Adjust the position of the multimeter to the buzzer or resistance position, and at one end of a cable, use one pen of the multimeter to ground (the earth is the common end), and the other to touch the cable to be calibrated; At the other end of the cable, short-circuit the calibrated cable to the ground. If the buzzer of the test pen sounds (the resistance is 0), the cable is the correct cable and can be marked. If the buzzer does not sound, you need to replace it with another cable. Repeat the above steps again until successful.

In the existing school line work, there are following problems:

1. It is not easy to find the common terminal during the calibration process, and when the earth is used as the common terminal, the site environment is too demanding, so it is not easy to use.

2. During the calibration process, it is necessary for the personnel at both ends of the cable to operate closely without making mistakes, but in actual operation, it is easy for the personnel at both ends to miss the contact points (the connection between the cable and the test lead, and the connection between the cable and the earth), resulting in alignment fail.

3. During the calibration process, the communication between the personnel at both ends of the cable is not convenient enough, and it is easy to get out of the line information problem during the communication, resulting in the failure of the line.

4. Only one cable can be calibrated alone, and multiple cables cannot be calibrated at the same time, which greatly affects the overall work efficiency.

The single-chip microcomputer is preferably STC89C52RC single-chip microcomputer.

Among them, the LED digital tube of the display unit can be displayed on the shell surface of the cable alignment device; the power supply module of the display unit is used to supply power for all electronic components in the display unit; the cable clamp extends out of the shell through the lead wire, and the other end of the lead wire Connect with LED digital tube.

The LED digital tube can receive and directly display the digital (constant) signal sent by the auxiliary machine, that is, it can visually display the corresponding calibrated line number. The LED digital tube is a seven-segment code display mode, which can display numbers from 0 to 9.

The power module is provided with a switch. A switch disconnects power when not in use.

The power supply module of the operation unit is used for power supply of all electronic components in the host; the cable clamp extends out of the shell through the lead wire, and the other end of the lead wire is connected to the pin of the STC89C52RC single-chip microcomputer.

The STC89C52RC MCU can output digital (constant) signals, and the output digital (constant) corresponds to the number of the cable clamp, that is, it can intuitively output the line number of the cable clamped by the cable clamp.

The shell of the operation unit is provided with a switch and a power indicator light. A switch disconnects power when not in use.

The number of cable clips of the display unit is two, and the number of cable clips of the operation unit is ten.

Among them, the cable clips of the display unit are respectively provided with red coating and black coating.

The use of cable clamps can avoid the effect of poor contact with the cable being calibrated.

For the convenience of communication, the display unit and the operation unit are respectively provided with voice modules, and the voice modules are respectively connected to the wireless module, microphone, speaker, control switch and voice adjustment module. Wherein, the microphone, the loudspeaker and the control switch are arranged on the surface of the casing.

The intercom communication distance on both sides of the special cable coupler can reach three kilometers. The communication module solves the problem of inconvenient communication.

The display module of the cable alignment device displays numbers from 1 to 9, which can calibrate 9 cables at the same time, and the LED digital tube is set in the center of the shell of the display unit, which is clearly visible.

The switch of the power module can disconnect the power supply when not in use, and then turn on the power supply when in use, prolonging the service life of the battery.

The cable alignment device can calibrate the wire numbers of bundled cables or multi-core cables. During operation, the numbers on the display module can be easily seen for quick marking. The dedicated cable alignment device can easily select the target for work through the built-in clamp. The common cable has been separated by two colors of black and red, which is clear at a glance.

Due to the reasonable overall design and simple structure of the special cable alignment device, the appearance size of the special cable alignment device is suitable for the operator to operate with one hand, and the remaining hand can do other things, which greatly improves the reliability of the equipment. Operability; the cable operation module is composed of cables and clamps; the overall equipment layout is reasonable, strong usability, and convenient for personnel to operate.

The working method of the special cable alignment device is: the two ends of the verified cable are respectively connected by the alignment device clips. The specific number of cables depends on the actual situation. After all the cables are connected, touch the red end of the display unit in turn. Touch the relevant cable, and the display unit will output the corresponding number on the display module at this time. At this time, the number is the same as the number marked on the operation unit, so the same cable is selected.

Since this pairing device uses a low-power, high-performance CMOS 8-bit microcontroller STC89C52RC microcontroller, the black cable clamp of the display unit is the COM terminal. When the black cable clamp is connected to the digital 0 line of the operation unit , at this time, you can check the line 1 to line 9. When the red cable clamp of the display unit touches a cable, the I/O port of the microcontroller outputs a digital code so that the LED digital tube receives the signal and will The strobe control of the displayed digital tube is turned on, and the corresponding number is displayed. For the same reason, the LED digital tube uses a dynamic display, so when the red end touches any cable, the corresponding I/O port will be Send out the corresponding digital code to make the LED digital tube display, write down the corresponding line number and make a mark, and the calibration line is completed.

The implementation steps of the specific cable alignment device are as follows:

The aligner is divided into display unit and operation unit. Turn on the power switch of the operation unit and check whether the power indicator light is normal. If the indicator light is dim or not on, the battery in the operation unit needs to be replaced.

1. When there are 7 cables to be tested (take 7 cables as an example): at one end of the cables to be tested, clamp the 7 cables with clamps No. 1 to No. 7 on the operation unit.

2. Turn on the power switch.

3. At the other end of the tested cable, use the display unit clamp, black clamp and red clamp to clamp the 7 cables. There is no need to move the black wire clips after clamping them. Use the red wire clips to touch the other 6 cables respectively.

4. At this time, the display unit will display the corresponding number on the LED when the red wire clip touches any cable. If the number 6 appears, the end of the operation unit is the one clamped by the wire clip on 6. The cable is the same cable.

5. Mark the completed cables individually and verify the remaining wires.

6. After everything is completed, remove the marked clips and turn off the power of the aligner.

In special cases, for example, if the conditions for two-person operation are not met, one person can perform calibration. At one end of the cable, connect the operation unit of the cable alignment device to each cable through the cable clamp, and turn on the power; then, the operator goes to the other end of the cable and uses the display unit for operation.

The comparative analysis of the multimeter and the special cable alignment device during calibration:

When verifying a cable: the multimeter pen touches the cable and must be firmly pressed against the cable to prevent the contact from loosening, and two people are required to operate at the same time, and the operation may fail; use a special cable aligner for the verification operation, The cable connection is secure and reliable with the cable clip, and the built-in intercom can also be used to talk over long distances.

When verifying multiple cables: the multimeter needs to be verified one by one, the efficiency is low, the success rate is low, and communication equipment is required for personnel communication, and communication is easily interrupted in places with poor signals; When testing multiple cables, you only need to clamp the multiple cables with the clamp, and the display unit will display the tested cables in turn, with high reliability and high success rate, and the working time is 20 times higher than that of Universal.
