Device processed employs Omron CPM1A-40CDR-A-V1 types programmable controller and 4 320 × 240 small liquid crystal displays are done
For main element circuit device；Employ 4 liquid crystal displays and show current corresponding device with Quick Response Code and the double explicit forms of Chinese character
4 prevailing operating state key nodes, the interface coding schedule and corresponding controller of the programmable controller of its controller is defeated
Enter end, output end interface see the table below：
In table, 5 tunnels of grounding switch, car switch, energy storage instruction, testing position and operating position from Devices to test
Input signal is respectively connected to PLC 1.00~1.04 input ports, by 10.02~11.06 output ends after PLC logical process
Mouthful, it is connected to Chinese character or the double aobvious display screens of Quick Response Code.
See Fig. 3, wherein, grounding switch, car switch, energy storage indicate that three display screens show two opposite work shapes
State；Testing position or operating position display screen show three working conditions, i.e. testing position, transitional intermediate positions and working position
Put, in this example, transitional intermediate positions we employ blank screen display mode.
Fig. 4 is the logic control flow process figure of programmable controller, and 5 tunnel input signals export 9 pulses by decision logic
Signal, 4 display screens of triggering, 8 Chinese characters of double displays or Quick Response Code and 1 invalid intermediate state (blank screen is shown).
Its groundwork process is data acquisition, is handled through input interface circuit and inputs to programmable controller, through logic
Exported after judgement processing and give Chinese character or Quick Response Code double aobvious display screens, then by display screen show default Chinese character or Quick Response Code or
Bar code.
The present invention operation principle be：
In order to not influence power supply-distribution system self-security and reliability, the present invention provide based on Quick Response Code or bar code
The input signal of equipment state liquid crystal display device be derived from 10KV transformer stations 1# incoming line switch cabinet panel leds, it is powered
Voltage is+220V direct currents, and this voltage Omron CPM1A-40CDR-A-V1 type programmable controller inputs can not be born,
Therefore input interface circuit need to be designed.
Omron CPM1A-40CDR-A-V1 type programmable controllers carry list+24V power supplys when doing input signal, and it is switched
It is 5mA to measure input electric current, when additional+12V voltages, and its input current is 2.5mA, and experiment is proved, the type programmable control
Device input voltage processed and electric current are linear, and input resistance is approximately 4.8K Ω or so, while test proves that working as input current
It is the type programmable controller job insecurity, unreliable during less than 2.2mA.Therefore in order to ensure reliability and security, input
Current design is between 2.5mA~5mA.As shown in Fig. 2 input interface circuit employs 5 68K Ω current-limiting resistances,
Now input current is 3.02mA, is verified through practical installation and trial, and system work is highly stable reliable.
The 1# incoming line switch cabinets panel leds of 10KV transformer stations mainly have earthing separating brake indicator lamp (green) or ground connection
Knife combined floodgate indicator lamp (red), car switch separating brake indicate (green) or close a floodgate to indicate (red), energy storage instruction (white), small
Stopping switch testing position indicates that (green) or operating position indicate seven main indicator lamps such as (red).Wherein, earthing separating brake
Indicator lamp (green) and earthing combined floodgate indicator lamp (red), car switch separating brake indicate that (green) indicates (red) with closing a floodgate
State is opposite.Input signal takes one.Thus, to be taken from earthing combined floodgate indicator lamp (red for our application example signal
Color), car switch close a floodgate indicate (red), energy storage indicate (white), testing position instruction (green) and operating position instruction
(red) five signal lamps.
Shown in control flow as shown in Figure 3, when earthing knife-switch combined floodgate red led access failure is lighted, the port of controller 1.00
No signal is inputted, and after programmable controller logic judgment, by 10.02 port output pulse signals, display shows that " 1# enters
Wiretap cabinet grounding switch has disconnected " text information and 2 D code information；, can when knife, which closes a floodgate, indicates that red colored lamp connection is lighted
There is signal input the port of programmable controller 1.00, after programmable controller logic judgment, by 10.03 ports output pulse letter
Number, display shows " 1# incoming line switch cabinet grounding switchs have been closed " text information and 2 D code information.
Similarly, when car switch combined floodgate red led or energy storage white indicating light access failure are lighted, PLC technology
The no signal of device 1.01 and 1.02 is inputted, after programmable controller logic judgment, exports arteries and veins by 10.04 and 11.00 ports respectively
Signal is rushed, two pieces of corresponding displays show " 1# incoming line switch cabinet car switches have disconnected " respectively and " 1# incoming line switch cabinets are small
Text information and the 2 D code informations such as the non-energy storage of stopping switch "；And car switch combined floodgate red led or energy storage white indicating light
When connection is lighted, there is signal input the port of programmable controller 1.01 and 1.02, after programmable controller logic judgment, point
Not by 10.05 and 11.01 port output pulse signals, two pieces of corresponding displays show that " 1# incoming line switch cabinet dollies are opened respectively
Pass has been closed " and text information and the 2 D code information such as " energy storage of 1# incoming line switch cabinets car switch ".
Car switch is in addition in testing position and the state of operating position two, in two state conversion process also
There is a temporal transition position.When testing position green indicating lamp is lighted, the port of programmable controller 1.03 has signal defeated
Enter, it is corresponding to show that device shows that " 1# inlet wires are opened by 11.04 port output pulse signals after programmable controller logic judgment
Pass cabinet car switch testing position " text information and 2 D code information；After car switch shakes out, if do not shaken to working position
When putting, testing position green indicating lamp and operating position red led all extinguish, and at this moment car switch is in an intermediate position,
The port of programmable controller 1.03 and 1.04 all no signals are inputted, at this moment, the port output control arteries and veins of programmable controller 1.06
Punching, blank screen；If car switch is shaken to operating position, operating position red led is lighted, programmable controller
There is signal input 1.04 ports, after programmable controller logic judgment, corresponding to show by 11.05 port output pulse signals
Device shows " 1# incoming line switch cabinet car switches operating position " text information and 2 D code information.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
