Abstract
Disclosed is a loud speaking telephone with an emergence stop locking circuit, comprising a box body, a sealing call locking plate, a sealing amplifier, an emergency stop locking circuit board, a press-to-talk button, a call button, a locking button, a microphone and a loudspeaker. The sealing call locking plate, the sealing amplifier, the emergency stop locking circuit board and the loudspeaker are arranged in the box body. The press-to-talk button is arranged on the upper part of the left side of a box cover and the call button is arranged on the lower part of the left side of the box cover. The locking button is arranged on the upper part of the right side of the box cover and the microphone is arranged on the lower part of the right side of the box cover. The call button is connected with the sealing call locking plate and the sealing amplifier; the sealing call locking plate is connected with the sealing amplifier; the sealing amplifier is connected with the loudspeaker, the microphone and the press-to-talk button; the locking button is connected with the sealing call locking plate and the emergency stop locking circuit board; and the emergency stop locking circuit board is connected with an external electrical control device through a 485 communication line. The loud speaking telephone with the emergence stop locking circuit has the beneficial effect that emergence stop locking can be achieved and fault sites can be displayed by connecting the external electrical control device.
Description
Technical field:
The utility model relates to a kind of hands free telephone, relates in particular to a kind of hands free telephone with the anxious lock circuit of closing down.
Background technology:
At present, hands free telephone commonly used can only realize by say, call out, the anxious lock of closing down, can not show the fault website when online with electric control gear.
The utility model content:
The utility model overcomes the deficiency that existing hands free telephone and electric control gear can not show the fault website when online, and a kind of hands free telephone with the anxious lock circuit of closing down is provided, and can realize anxious lock and the demonstration fault website of closing down when this hands free telephone and electric control gear are online.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hands free telephone with the anxious lock circuit of closing down, by casing, sealing call out latch plate, seal amplifier, the anxious lock circuit plate of closing down, by saying that button, call button, latch buttons, Mike and loud speaker form.Sealing calling latch plate, seal amplifier, the anxious lock circuit plate of closing down, loud speaker are contained in the casing.The case lid left upper portion is provided with by saying button, and the bottom is provided with call button.The case lid right upper portion is provided with latch buttons, and the bottom is provided with Mike.Call button is called out latch plate with sealing, seal amplifier is connected, sealing is called out latch plate and is connected with seal amplifier, seal amplifier and loud speaker, Mike, by saying that button is connected, latch buttons is called out latch plate with sealing, the anxious lock circuit plate of closing down is connected, and the lock circuit plate of suddenly closing down is connected with extraneous electric control gear by 485 connections.
During work, press by saying button, sound source can be carried out single worker's conversation facing to Mike, presses call button and can send call signal.One group of normally opened contact of latch buttons is connected with the anxious lock circuit plate of closing down, when pressing latch buttons, a kind of normally opened contact closure of latch buttons is to the anxious triggering signal of lock circuit plate of closing down, signal sends extraneous electric control gear to by 485 connections, realizes anxious lock and the demonstration fault website of closing down.
The beneficial effects of the utility model are can realize anxious lock and the demonstration fault website of closing down with extraneous electric control gear is online.
