Description
Technical field
The utility model relates to elevator technology field, especially a kind of elevator audio call and broadcast device.
Background technique
Existing elevator voice system is typically all interactive mode, is similar to intercom.Due to the limitation of elevator, lead to
The voice system uses wired connection (wireless signal is very faint) for often, and data line includes the trailing cable in elevator
It is interior.Find in the experience and lessons of multiple accident: elevator trailing cable can be broken, and voice system is caused to interrupt completely, by
It is panic that this can cause personnel in elevator.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides one kind and can start at once after trailing cable is broken
The dedicated broadcast device of elevator pacifying voice broadcast and calling for help outward.
The technical solution of the utility model are as follows:
A kind of elevator audio call and broadcast device, it is characterised in that: it includes computer room phone, carriage phone, button
The signal connection end of battery, battery, normally closed switch and reporting machine, the computer room phone connects carriage phone by telephone wire
Signal connection end, the carriage phone are equipped with call button, and the power connector end of the carriage phone connects electric power storage by electric wire
The power input of the power output end in pond, the battery is connected with charger by electric wire, and the charger passes through electric wire
It is connected with mains connection, the power output end of the battery also connects the power input of normally closed switch by electric wire, described
The power output end of normally closed switch connects the power input of reporting machine by electric wire, and the button cell is connected by data line
The signal connection end of normally closed switch.
Further, the button cell is rechargeable battery, and the button cell is connected with the second charger.
Further, the electric wire between the data line, telephone wire and charger and mains connection penetrate elevator with
The cable joint-box of row cable is prolonged the service life by the protective action of cable joint-box.
Further, the built-in storage battery emergency light.
Working principle of the utility model is:
Since the electric wire between data line, telephone wire and charger and mains connection penetrates the electricity of elevator trailing cable
Cable set, cable are intended to solid than above-mentioned three, if cable is broken, in general above-mentioned three should also be broken；At this time
Phone contact is necessarily interrupted, and button cell also no longer sends a signal to normally closed switch (having signal disconnection, no signal closure), then
Normally closed switch closure, reporting machine, which is powered, starts the voice prerecorded of casting, for comforting the personnel in lift car, allow its not
Want panic, should not opening elevator door without authorization, bear with rescue.
The utility model has the following beneficial effects: due to the fracture of trailing cable, phone failure in carriage, but can lead to
The effects of crossing reporting machine and play voice, playing comfort, calmness is reduced the self inflicted injury of personnel in carriage, is accidentally injured.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, button cell；2, mains connection；3, computer room phone；4, carriage phone；5, call button；6, battery；
7, charger；8, normally closed switch；9, reporting machine.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of elevator audio call and broadcast device, it includes computer room phone 3, carriage phone 4, button
The signal connection end of battery 1, battery 6, normally closed switch 8 and reporting machine 9, the computer room phone 3 connects carriage by telephone wire
The signal connection end of phone 4, the carriage phone 4 are equipped with call button 5, and the power connector end of the carriage phone 4 passes through electricity
Line connects the power output end of battery 6, and the power input of the battery 6 is connected with charger 7 by electric wire, described to fill
Electric appliance 7 is connected with mains connection 2 by electric wire, and the power output end of the battery 6 also connects normally closed switch 8 by electric wire
Power input, the power output end of the normally closed switch 8 connect the power input of reporting machine 9, the button by electric wire
Battery 1 connects the signal connection end of normally closed switch 8 by data line.
The button cell 1 is rechargeable battery, and the button cell 1 is connected with the second charger, and (usual means, do not scheme
Show).
Electric wire between the data line, telephone wire and charger 7 and mains connection 2 penetrates elevator trailing cable
Cable joint-box.
Emergency light built in the battery 6.
In the present embodiment, the detailed description of each accessory:
The description of the embodiments and the specification only illustrate the principle of the present utility model and most preferred embodiment, is not taking off
Under the premise of from the spirit and scope of the utility model, the utility model also has various changes and improvements, these changes and improvements
It falls within the scope of the claimed invention.
