Abstract
The invention relates to a tripping press plate capable of expanding a connection loop and an information transmission circuit. The press plate comprises four wiring terminals, wherein one pair of terminals is connected with control loops; and one pair of terminals is connected with signal loops, so that the target of completely isolating two groups of loops is achieved. When protective tripping press plates are input, a connecting plate is located in a tripping control loop, so that achievement of outlet tripping is ensured. The protective tripping press plates are connected to the signal loops when output, and each tripping press plate can transmit state information to a dispatcher as one path of remote signal when output, so that the disadvantage that input or output information cannot be uploaded when a traditional tripping press plate is connected to the control loops is overcome; the input or output state of the press plate is directly transmitted to a dispatching terminal through the signal loops; unreliable factors of an artificial report are eliminated; an operator in charge can understand the input or output state at a glance; and the input or output state of each protective press plate is intuitively determined.

Connecting the positive power source terminal of measure and control device, the other end connects optocoupler terminal block, out accesses observing and controlling from terminal block
The input of device, thus status information is moved back in pressing plate throwing and passes to scheduling.It is connected on control when pressing plate puts into
The 1 of loop processed, 2 positions, be connected on when pressing plate exits the signal circuit completely isolated with controlling loop 3,
4 positions, pressing plate is connected with measure and control device, and then the information that exited by each road pressing plate is by optocoupler terminal block
Open as a road and access measure and control device into remote signalling, be thus delivered to scheduling.
Protection pressure plate structure in the present invention is simple, dependable performance, and can be by information circuits by pressing plate
The throwing state of moving back is transmitted directly to dispatching terminal, eliminates the unreliable factor of artificial report, makes operator on duty one tunnel
It is clear, intuitively determines that state is moved back in the throwing of protection pressing plate.
