Abstract
A kind of wiring faults analog board, including the bus switching circuit being connected with peripheral control unit by bus, bus switching circuit is connected with CPU, relay driving is connected on CPU, relay driving connection relay row, back panel wiring row and external cabling row are connected with relay row, the two ends of the connecting line of connection equipment under test respectively are arranged in the back panel wiring row and external cabling.Each relay that the utility model is arranged using relay is corresponding with each binding post for the equipment for needing to simulate, and simulates the break-make of connecting line by the break-make of relay, reaches the effect of simulation.
Description
Technical field
The utility model is related to a kind of fault simulation plate, more particularly to a kind of wiring faults analog board.
Background technology
Locomotive driving failure is being simulated or during teaching, training, it is sometimes necessary to the connecting line in locomotive equipment
Terminals inside slave unit are simulated to the break-make between outside binding post, so as to reach preferably simulate effect or
Person's teaching efficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of wiring faults analog board, deposited with solving prior art
The problem of.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of wiring faults analog board, including the bus switching circuit being connected with peripheral control unit by bus, bus
Change-over circuit is connected with CPU, is connected and is connected with relay driving, relay driving connection relay row, relay row on CPU
Back panel wiring is arranged and external cabling row, and the back panel wiring row and external cabling arrange the two of the connecting line of connection equipment under test respectively
End.
Trouble shooting is also associated with the CPU by key row, the back panel wiring row and external cabling row are all connected with failure
Contact wire jumper row.
The bus is RS485 buses, and the bus switching circuit is RS485 change-over circuits.
The fault simulation plate sets multiple, all binding posts of multiple fault simulation plate cover measurement equipments.
The beneficial effects of the utility model：Each relay and need that simulates to set that the utility model is arranged using relay
Standby each binding post correspondence, simulates the break-make of connecting line by the break-make of relay, reaches the effect of simulation.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of wiring faults analog board, including the bus being connected with peripheral control unit by bus
Change-over circuit, bus switching circuit is connected with CPU, and relay driving is connected on CPU, and relay driving connection relay is arranged, after
Back panel wiring row and external cabling row are connected with electrical equipment row, back panel wiring row and external cabling are arranged connects equipment under test respectively
The two ends of connecting line.
If equipment under test connecting line is more, multiple, multiple fault simulation plate cover measurement equipments can be set in fault simulation plate
All binding posts.
Trouble shooting is also associated with CPU by key row, the back panel wiring row and external cabling row are all connected with fault contact
Wire jumper is arranged.
And above-mentioned bus is RS485 buses, bus switching circuit is RS485 change-over circuits.
Wiring faults analog board of the present utility model is used for the break-make of analog machine connecting line, if necessary to a certain company
The break-make of wiring is simulated, then by disconnecting the relay being connected in relay row with the root connecting line, breaking inner wiring
Contact between row and external cabling row, and send a signal to controller.
Controller can directly transmit disconnection signal and give CPU minimum systems, and CPU minimum systems are corresponding by relay driving
Relay acted, simulation broken string.
After the completion of simulation, by pressing trouble shooting by corresponding button in key row, relay row is sent a signal to, will be after
Electrical equipment adhesive, releases fault simulation.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
