The utility model content:
For overcoming the shortcoming of prior art, the utility model discloses and a kind ofly have 485 and Ethernet interface, and the intelligence five anti-analog control screens by the blue tooth interface subpoena, this five anti-analog control screen also has the outage memory function simultaneously.
The technical solution adopted in the utility model is as follows:
A kind of intelligent five anti-analog control screens, it is characterized in that: include cpu motherboard, cpu motherboard power supply POWER, five preventing keys, include CPU, blue tooth interface and the communication interface that is connected with CPU, output interface, button, RAM on the cpu motherboard, RAM also is connected with battery, cpu motherboard is connected with output bus by output interface, be parallel with remote measurement plate, remote signalling plate on the output bus, be connected with telemeter on the remote measurement plate, be connected with the remote signalling lamp on the remote signalling plate, cpu motherboard is connected with five preventing key communications by blue tooth interface.
Described a kind of intelligent five anti-analog control screens, it is characterized in that: the communication interface of described cpu motherboard is supported 485 bus communications and ethernet communication.
Described a kind of intelligent five anti-analog control screens is characterized in that: the five anti-supporting uses of lockset of described five preventing keys and device context.
Described a kind of intelligent five anti-analog control screens, it is characterized in that: described each remote measurement plate can connect 32 telemeters, and each remote signalling plate also can connect 32 remote signalling lamps.
Operation principle of the present utility model is:
Cpu motherboard carries out communication by communication interface and RTU or comprehensive automation of electric power system monitoring backstage, behind the message that the CPU inter-process on the cpu motherboard is received, by the output interface on cpu motherboard output remote measurement and remote signalling value to output bus, the remote measurement plate that is parallel on the output bus drives telemeter, show the remote measurement value, the remote signalling plate that is parallel on the output bus drives remote signalling lamp display switch amount, RAM in the cpu motherboard is used to store remote measurement amount and remote signalling amount, power by the cpu motherboard power supply under the RAM normal condition, when the cpu motherboard power supply has a power failure, power by the battery on the cpu motherboard, when having guaranteed the imitation screen power cut-off, cpu motherboard has the power-failure memory function, can carry out the manual of corresponding remote signalling lamp and telemeter by the button on the cpu motherboard simultaneously is provided with, prestored five anti-rules of the last operation of equipment of imitation screen of cpu motherboard, when the person on duty simulates five-prevention operation on imitation screen, cpu motherboard is judged according to the five anti-rules that are pre-stored in mainboard CPU, while generating run step, blue tooth interface on the cpu motherboard passes the operation order that generates and instructs on five preventing keys, the person on duty unblanks to five anti-locksets according to operating sequence to device context with five preventing keys, and carries out corresponding grid switching operation.
The beneficial effects of the utility model:
1,485 buses and Ethernet adopt difference mode signal, and the electromagnetic interference at scene is had the good restraining effect.
2, this device has the power-failure memory function simultaneously, send electric energy enough to show the remote measurement amount and the remote signalling amount of the preceding primary system of power failure after imitation screen is cut off once more.
3, Bluetooth transmission has omni-directional, and long transmission distance makes the communication of five preventing keys and five anti-imitation screens more stable simultaneously.
