Description

The emergency communicator of elevator cage

The utility model relates to a kind of emergency communicator of elevator cage.

The emergency communicator of general traditional elevator cage mostly is to press alarm bell in the compartment with the trapped person, makes elevator(lift) machine room or building guard personnel vigilance, talks with and provides assistance by phone in the machine room and the interphone in the compartment.But some elevator user once had unhappy, unfortunate experience, was exactly all next the building personnel, and being closed in the deep of night seeks help in the elevator of et out of order does not have door and then cause unfortunate accident.So safety in order to ensure the elevator user, some manufacturing industry of the lift persons are except installing interphone and the alarm bell in the elevator cage according to the telecommunication law relevant regulations, more provide one can directly get in touch with extraneous city telephone set, the personnel of stranded what elevator can outwards be required assistance by approach.Though yet this method has more safety control, but in installation process, following problem is arranged:

(1) machine of having a telephone installed in the elevator cage not only destroys the conformability of overall appearance, more produces the problem of structural failure; Especially the use of telephone set is difficult to control, and gesture causes many meaningless dialogues and waste.

(2) telephone wire must find untapped circuit to connect in movable cable, and erection work is added to the difficulties.(3) stranded personnel in the fault elevator, often nervous, lose one's head or with originally can't speech, so even there is phone to seek help to the external world, but often can't circulate a notice of out correct generation address, and elevator number and lose the first chance of rescue rapidly.

The purpose of this utility model provides a kind of emergency communicator of elevator cage, this device utilizes the basic circuit of original elevator interphone, signal converting is arrived telephone wire, the running of microprocessor and software program by phone, can dial several telephone numbers according to the order wheel of setting, the indicator of trapped personnel in the compartment is in time required assistance to the external world after telephone wire is connected via interphone.

Another purpose of the present utility model provides a kind of emergency communicator of elevator cage, but stranded place and the elevator number of voice circular that the prior burning of this device nationality is good, the people who makes stranded what elevator dials immediately behind the emergency closing of the circuit and releases, the opportunity that the people that comes to rescue can be grasped correct address rapidly, rob the people that is rescued is to reduce the generation of mis-adventure.

A purpose more of the present utility model provides a kind of emergency communicator of elevator cage, but this device nationality is by half worker worker's automatic switch-over circuit, eliminate the interphone signal and send into the reflection sidetone that telephone wire causes, avoid the compartment phone to amplify back clamoring of self coupling of generation and cry, to keep the quality of both sides' conversation.

The utility model is achieved in that a kind of emergency communicator of elevator cage, and the microphone phone that includes the microphone phone of the interphone that makes in the elevator cage and elevator(lift) machine room and guard room, building is reached and linked up attached cable and movable cable; It is characterized in that: the basic composition structure of this device at least also comprises: one is mounted on the interphone in the compartment, at least one group is connected with being located at of telephone wire microphone phone and this phone bonded assembly signal conversion interface in the elevator(lift) machine room and that be located at the guard room, building, wherein, this signal conversion interface includes a half duplex operation automatic switch-over circuit of each circuit working of control again at least, the simulation multiplexer, one phone interface, and the answering circuit of microprocessor and memory device thereof and Gong recording playback voice that are connected with microprocessor with the simulation multiplexer, the software program running of the microprocessor by the signal conversion interface, make it after monitoring by the alarm bell signal that interphone sent in the compartment, can dialing control be proposed to the phone interface, and nationality will be set several in advance by phone institute bonded assembly telephone wire and take turns to dial the number and connect according to priority in memory device, personnel in the stranded what elevator cage can also be required assistance to the external world at leisure under operating personal or machine room personnel's situation.

Wherein alarm bell signal monitoring is set and must continues by a second, but or continuously discontinuously by calling out just dialing/receiving calling of alarm button, in order to avoid cause meaningless contact because of the false touch alarm bell.

Need postpone delay time of dialing/receiving calling just a period of time when wherein microprocessor preestablishes and in the elevator cage call demand arranged, have personnel can preferentially respond this calling sequence for taking on-the-spot machine room or caretaker room into account this delay time.

Wherein the half duplex operation automatic switch-over circuit is made of the monitoring in the semiconductor integrated circuit, comparator circuit, make signal that interphone imports in comparison by the background noise environment, be confirmed as under the real conditions, carry out potential monitoring and automatic switching function again, make interphone signal of sending to and the signal identification to some extent of sending into interphone, and produce to isolate, avoid interference and clamor and cry.

Wherein can include the voice module that a fixed type voice module and can be recorded in the answering circuit of recording playback voice; Wherein the fixed type voice are mainly recorded and are pacified the passenger who locks in the elevator cage, make its to elevator faults can the overreaction anxiety voice; The voice module that can record is then recorded the voice that change with actual conditions, address, number number as elevator, even make the trapped person under alarmed situation, still can allow the people who comes to rescue grasp correct information by the broadcast of these voice, strive for timeliness and life.

Characteristics of the present utility model are to utilize switching phone in-to-in microprocessor and the software program that is connected with telephone line, except above-mentioned functions, can also provide following all multi-functional:

(1) can or connect 6 elevators for the elevator use of single portion and use, elevator quantity can freely be set by computer.

(2) press in the elevator cage when calling out, dialing/receiving calling possesses the mistake of preventing simultaneously by worker's energy automatically, and promptly call button must continue by a second, or just can set dialing/receiving calling by call button discontinuously continuously.

(3) when the elevator cage call demand is arranged, can set postpone a period of time dialing/receiving calling just by computer, be to respond the priority of this calling for taking on-the-spot machine room or caretaker room into account this delay time, then set by computer delay time to what in advance.

(4) have the answering of voice guide, can pacify stranded passenger earlier.

(5) can customized special software, make it possess far-end remote control check man (RESET) output of and resetting.
