The utility model proposes visual anti-explosion talkback device for a kind of protection works.Described visual anti-explosion talkback device comprises explosion-resistant enclosure, intercommunication module in button, intercommunication module outdoors, door outdoors, outdoors electric bell in display module, door in video module, door; Button is connected with electric bell, intercommunication module outdoors in door respectively outdoors; Intercommunication module outdoors, video module is arranged in explosion-resistant enclosure with button outdoors outdoors, and in door, in intercommunication module, door, display module and Men Nei electric bell are arranged in protection works.The utility model device both can have been realized vocative function, can realize again video intercom function, exchanged with the personnel's of entering video voice messaging thereby realize the inner operator on duty of engineering; Adopt sidetone bucking circuit to make intercommunication clear sound loud and clear, effectively intercommunication distance more than 200 meters, has stronger protective capacities.
Description
Technical field
The utility model belongs to antiaircraft technical field, specifically refers to visual anti-explosion talkback device for a kind of protection works.
Background technology
Civil air defense constructions and installations design standard regulation: at the main gateway of each protective unit personnel in wartime protection airtight outer side of door, a call button that has protective capacities should be set, as shown in Figure 1.Act as and refer in the time of gas filtration ventilation, implementing control personnel comes in and goes out, dissimilar civil air defense constructions and installations has different number ratios, before external staff will enter civil air defense constructions and installations, the permission that first will obtain inner operator on duty just can enter, but also will disinfect through decontamination, for this reason and the cue arranging.
Call button, be again antiknock doorbell, product comprises the base with containing cavity, button is arranged in containing cavity, liner plate covers on described base, and on this liner plate, the corresponding button place ringing the doorbell is provided with through hole, cover on liner plate with the upper cover plate of through hole, and form storage tank between liner plate and upper cover plate, the rotating through hole that is arranged in storage tank and is partly exposed at cover plate of rotating disk, the through hole corresponding with through hole on liner plate offer dial rotation to appropriate location on rotating disk time, is separately outwards provided with handle on described rotating disk; Owing to ringing the doorbell to be arranged in shockproof explosion-proof base, even if having strong external impacts also cannot damage electricity rings the doorbell, ensure its fail safe, when use, turning handle, make the through hole on rotating disk corresponding with the through hole on liner plate, hand just can extend into be pressed button and allows the people of the inside know in base, open in time sealed door.
Current call button can only transmit one and call switching signal, the inner operator on duty of engineering cannot with the further exchange of information of the personnel of entering, None-identified bearer identity or inform messenger's points for attention.Therefore need to develop one antiknock video intercom device cheaply, also there is protective capacities, have vocative function and video intercom function concurrently, there is important use value.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, proposes visual anti-explosion talkback device for a kind of protection works.Described visual anti-explosion talkback device increases the intercommunication module with sidetone cancel function in original call button, intercommunication telephone is set in protection works, in the situation that reliability does not reduce, both can realize the vocative function of original call button, can realize again intercommunication function, thereby realize the inner operator on duty of engineering and the personnel's that enter information interchange, identify bearer identity or inform messenger's points for attention; Also there is protective capacities, have vocative function and intercommunication function concurrently, there is important use value.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of visual anti-explosion talkback device protection works for, comprises explosion-resistant enclosure, intercommunication module, outdoors display module, the interior electric bell of door in video module, door in button, intercommunication module outdoors, door outdoors;
