The condition of collecting carries out sequentially-operating, and logically relationship carries out the control of interlock protection movement, and the data of a large amount of discrete magnitudes are adopted
Collection.It is newly exactly that each artificial is simplified primary " switch " to line movement that this is practical, special using the switching logic of PLC controller
Property collect each " switch " movement, can be " switching " each time by the logical relation at pre-set " switch " both ends
Result be shown in terminal human-computer interaction module and give bulletin.Which improves working efficiencies, reduce the general of error
Rate ensure that the stabilization of quality.
Detailed description of the invention
Fig. 1 is the structure block diagram of the utility model.
Fig. 2 is the electronic schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
Passenger train electric control circuit shown in FIG. 1 includes PLC controller 1 to line machine, PLC controller 1 it is defeated
Enter end and be connected with electric resistance array 2 and end of probe electronic switch 3, the output end of PLC controller is connected with switching tube array 5 and people
The power supply of machine interactive module 6, PLC controller 1, human-computer interaction module 6 and end of probe electronic switch 3 is mentioned by power module 4
For.
In the present embodiment, electric resistance array 2 is made of R1~R16,16 resistance；Switching tube array 5 is by Q1~Q48, and 48
Switching tube is constituted；End of probe electronic switch 3 is close to inductive switch；Human-computer interaction module 6 is touch screen；Power module 4 is PLC
Controller power source special module.
The working principle of the utility model are as follows:
1, basic principle:
1.1 couples of current live artificial nucleus identify the movement of wiring: no matter discovery is using multimeter or battery lamp
It checks, essence is all determine whether wiring both ends are same root wiring with one " on-off ".In the neck of electric automatization
" on-off " function is easiest to realize and automatically control inside domain.Both the verification one by one in practical maintenance was reduced to a switch
Movement.
1.2 use PLC controller (Programmable Logic Controller), and i.e. we are popular for PLC controller
The programmable controller said: and what PLC controller was most good at is exactly a large amount of switching value sequential control, its logically item
Part carries out sequentially-operating, and logically relationship carries out the control of interlock protection movement, and the data acquisition of a large amount of discrete magnitudes.
Simply say: the utility model is exactly that each artificial is simplified primary " switch " to line movement, is controlled using PLC
The switching logic characteristic of device processed collects each " switch " movement can be with by presetting the logical relation at " switch " both ends
The result " switched " each time is shown on terminal " touch screen " and gives bulletin.
2, principle illustrates:
According to above-mentioned mentality of designing and basic principle, the electrical schematic diagram that we devise the utility model (is detailed in attached drawing
2 :), the working principle of the electrical schematic diagram:
According to rail truck wiring at most a branch of characteristic for having 43 wirings, the machine can using 1 input and output of PLC controller
With the characteristic that dot matrix sequence is arranged, it is provided with 8 × 6 matrix (row com1~8；Section 1000~1005) (according to wiring line from now on
The variation of beam can increase expansion module to solve the increased amount of possibility of wiring).Head is respectively set in we in this dot matrix
Two kinds of operating modes are arranged according to the form of wiring in tail end:
(1) there is the wiring of standard connector at both ends:
Both ends connector respectively as two ends, after setting certain work-based logic, PLC controller be can control in point
Automatic cycle detection and matching, state a little are judged by the matrix of scan round 8 × 6, this just realizes this to line machine in battle array
Automatic detection function.
It detects work:
Successively trigger Q1, Q2 from the first input end com1 of PLC controller 1 ... Q8, Q9 ... Q48 switching tube, PLC
Second input terminal com2 of controller 1 successively trigger Q1, Q2 ... Q48 switching tube；If some switching tube is led in this process
It is logical, it feeds back to induction signal to the V of PLC controller 10~7End, then feeds this information to the register mode area DM of PLC controller 1, then
Illustrate that this root line and corresponding position are connections；If there is multiple switch pipe triggering and conducting, then illustrate harness internal wirings it
Between had connection short circuit；If there is some or several switching tubes are never triggered in entire cyclic process, just
Show that this root line or several threads are not connected to open circuit.
Such as: there is one group of 39 core connector, after the connection of both ends, head end is triggered since com1, and output end is just in Q1 and Q39
Between circuit sequentially detection, Line 1 a terminates high level, the end b high level by being sent into switching tube Q1 transmitting close to inductive switch
Pole, the section of PLC controller 1 select signal IO0 output low level to send by resistance R17 to the base stage of switching tube Q1, and switching tube Q1 is led
It is logical, it is sent into the end V1 of PLC controller 1 after switching tube Q1 collector output signal partial pressure, then feeds this information to PLC control
The register mode area DM of device 1, with wire size and the position that can show this root wiring after standard comparison on the touchscreen；Line 1 is entire
After process circulation is completed, section 0-5 is successively sent into low level by PLC controller 1, detects remaining wiring, and automatically from No. 2 lines
Start this process, until 39 lines of head end all complete by circulation.
(2) there was only the wiring of single-ended connector:
One end with connector is set as tail end, the other end of connector is not set as head end.Since PLC is controlled
Device 1 can not carry out automatic identification to the wiring head end, and so polygamy line is patched one time again in other words will lead to inefficiency,
Therefore manual mode is opened.
Its detect work be exactly from by triggering close to inductive switch, it is single to randomly choose certain and start to examine all the way
It surveys.
Com1 triggers Q1, Q2 ... Q8, Q9 ... Q48 switching tube.
Such as: still there is one group of 39 core connector, (PLC controller 1 can be with to line machine there is connector one end to be connected to
To this one end automatically scanning and inspection), when randomly selecting single line from harness, using one close to inductive switch, controlled with PLC
Device 1 processed is connected to, and PLC controller 1 collects corresponding number after the conducting of some switching tube, and the on state of wiring is sent into
The register mode area DM, with wire size and the position that can show this root wiring after standard comparison on the touchscreen.
3, human-computer interaction module 6:
Human-computer interaction module 6 is characteristic that is programmable using PLC controller 1, can interacting to realize, by original each
The wire size of class standard wiring, position, which map out, to be come, and realizes that register mode area signal is converted into visual text by computer programming
Or picture signal, and human-computer interaction may be implemented.
