Description
Technical field
The utility model relates to a kind of core aligning device for cables that is applied to electric power, communication cable construction.
Background technology
In transformer station a large amount of use control cables, for the protection of device to the control of field apparatus, measurement etc.Because the core number of control cables is many, in order to guarantee the correctness of wiring, before wiring, to carry out core, find out correct one-to-one relationship, and to putting on identical label according to purposes on identical core table.The method of being used in a large number is now to carry out core with multimeter.This method is mainly by multimeter, to be completed at cable two ends by two staff, a wherein core of first determining cable is common core, wherein one end staff is by common core and the cable core short circuit to be determined of choosing, other end staff tests common core and the cable core of choosing at random with multimeter break-make shelves, until multimeter hummer sounding, then two ends staff is determined this cable core and is marked upper corresponding label simultaneously by intercom or phone contact.With multimeter, carry out affected by staff on the method for core larger, unreliable, and this method wants looking for of a core of a core, more time-consuming, efficiency is not high.
Summary of the invention
The problem existing for solving prior art, the utility model provides a kind of portable mobile wireless to core device, and its technical scheme of taking is:
Comprise microcontroller, wireless communication module, power module, LCD MODULE, keyboard load module, decoding module, coding module and light-coupled isolation module, wireless communication module, power module and LCD MODULE are connected respectively microcontroller, keyboard load module connects microcontroller by scrambler, decoding module is connected microcontroller by selector switch respectively with coding module, one end of light-coupled isolation module connects decoding module and coding module simultaneously, its other end stube cable interface, microcontroller also connects crystal oscillator.
The utility model as long as all heart yearns of cable are received on the interface of core device, automatically detects heart yearn the control chip of core device, and by liquid crystal display, goes out the corresponding relation of heart yearn, has feature high to core good reliability, efficiency, easy operating.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model;
Fig. 2 is external structure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, microcontroller 1 be take STC89C52 single-chip microcomputer as core, and STC89C52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers that STC Corporation produces.Wireless communication module 2 adopts NRF905 radio receiving transmitting module, and it is little that this module has volume, long transmission distance, anti-interference strong, the stable advantage of communicating by letter, wireless communication module 2 adopts serial interface communication mode with communicating by letter of microcontroller 1, so wireless communication module 2 is received the P of single-chip microcomputer
3.0, P
3.1on interface.Power module 3 application LM7805 chips are powered to single-chip microcomputer, and the positive supply of 5V and ground are received respectively on the VCC and VSS pin of single-chip microcomputer.Power module 3 application LM317 chips provide voltage to wireless communication module 2 simultaneously.LCD MODULE 4 is selected 12864 Liquid Crystal Modules, and in order to save I/O interface, the data communication of 12864 Liquid Crystal Modules and single-chip microcomputer adopts serial communication.Keyboard load module 5 mainly contains to be controlled button and edits two kinds of input keys, control button and be mainly the control carried out up and down and the selection of function, editor's input key is mainly the coding of input core mark, and these buttons on keyboard load module 5 are received the P of single-chip microcomputer through seven pins of scrambler 12
2.0-P
2.6on pin.
Because general control cables core is many, what core was many has more than ten, therefore coder module 11 and decoder module 8 between single-chip microcomputer and cable interface 10, have been added, to at the two ends of cable, connect core device when to core simultaneously, two wherein have one to be main to core device to core device, another is auxiliary to core device, main core device is exported to high level to cable, and the auxiliary low and high level that core device is mainly detected to every heart yearn makes a decision foundation.Therefore the core test section to core device at two ends is different, therefore before coder module 11 and decoder module 8, has added selector switch 7, by the P of single-chip microcomputer
1.5control selector switch 7, when this equipment being set when test and being main equipment, P
1.5pin output low level, the P of single-chip microcomputer
1.0-P
1.4receive in decoder module 8, when this equipment being set when standby for additionally arranging, P
1.5pin output high level, the P of single-chip microcomputer
1.0-P
1.4receive in coder module 11.Because microcontroller 1, coder module 11 are 5V voltage with decoder module 8 uses, and the test voltage of core disturbs in order to reduce the cell voltage of selecting 9V, therefore between coder module 11, decoder module 8 and cable interface 10, added light-coupled isolation module 11.
As shown in Figure 2, the antenna 13 of wireless communication module 2 is located at the top of shell 12, cable interface 10 is located at the sidewall of shell 12, and the display 14 in LCD MODULE 4, the power switch 15 on power module 3 and the control button 16 on keyboard load module 5 and edit key 17 are located at respectively on shell 12 front panels.
While carrying out core, by the setting of selector switch 7, two, to core device, one of them is main to core device, another is auxiliary to core device, the two ends of cable connect respectively main to core device and auxiliary on the cable interface 10 of core device, by main, control button 16 on core device are carried out to wireless connections, and the antenna 13 by separately carries out communication, by the main label to the every core of edit key 17 editors on core device, main corresponding order and the label information that will show each core of two ends to the display 14 on core device.
