Description
Technical field
The present invention relates to a kind of long distance wireless intercom systems, call and use especially suitable for elevator emergency, it is remote to belong to elevator
Journey wireless intercom system technical field.
Background technology
At present, elevator emergency intercom system in the market is mainly communicated using wired mode, also have using FM without
Line intercommunication is communicated by simple GSM modes, and above-mentioned three kinds of communication modes have the following disadvantages：
1st, wired mode：It is a kind of simplest intercommunication mode from the point of view of technical aspect, but connecting up needs a large amount of line
Material, early period, difficulty of construction was big, long in time limit, costly, caused call tone quality unintelligible because circuit distance is longer, elevator management personnel
Can not accomplish 24 hours it is on duty, if operator on duty because thing is away from keyboard, can missed call.Investigate cumbersome, later stage line in trouble point
Road maintenance cost is high, and a series of problems causes most users to hang back；
2nd, FM wireless talkbacks mode:This mode, although solving many drawbacks of wired intercom, also there are many offices
Sex-limited, so communication environment just becomes quite important, if cell building is excessively intensive, is because be to use wireless communication mode
Electromagnetic wave propagation is highly detrimental to, causes communication distance near, speech quality is poor, is easily disturbed, and the air time is limited to 2 points
It (is provided in elevator inspection rule TSG T7001-2009 files within clock：Lasting call must be obtained in cab with duty room to contact),
Elevator management personnel can not accomplish 24 hours it is on duty the problems such as, if operator on duty because thing is away from keyboard, can missed call；
3rd, simple GSM modes：This mode is communicated using GSM network, perfect can solve wired and FM this two
The shortcoming of kind communication mode, but this mode, each building are needed using a GSM card, if entire cell building
If quantity is more, cost of use just becomes very high, and manages, also fairly cumbersome.Differentiation elevator that cannot be detailed is cried for help
Address when trapped person does not know to be trapped in certain elevator, can cause rescue to have no way of handling.
Invention content
In place of solving above-mentioned the shortcomings of the prior art, it is low to provide a kind of operation cost, energy
Enough accomplish long-term line, real time phone call, performance is stablized, flexible and convenient to use, without largely connecting up, only needs a SIM card
Realize the elevator long distance wireless intercom system of all elevator emergency callings of entire cell.
The present invention is achieved through the following technical solutions：
Elevator long distance wireless intercom system is characterized in that including car communication 1, computer room extension set 2, GSM hosts
3rd, duty room terminal 4, car communication 1 are connected by trailing cable 7 and the communication of computer room extension set 2, computer room extension set 2 and GSM hosts 3
Between by UHF Radio Links 5 communicate connect, between GSM hosts 3 and duty room terminal 4 pass through GSM network 6 communication connection；
The UHF Radio Links 5 are using frequency range in the uhf band of 409-462MHz, modulation system FM, channel
Bandwidth is 12.5KHz；
The car communication 1 includes loud speaker and pickup transmitter, and loud speaker passes through trailing cable and machine with pickup transmitter
Room extension set 2 is connected；
The computer room extension set 2 includes CPU processor and coupled extension set electric power system, extension set UHF transmitting-receivings
Device；
The GSM hosts 3 include CPU processor and coupled host supplying power system, host UHF transceivers,
Gsm module, sim module；
In order to be continuing with after a loss of power, a lithium battery is respectively provided in the computer room extension set 2 and GSM hosts 3；
The duty room terminal 4 is GSM mobile handset or fixed-line telephone；
The computer room extension set 2 connects 1-4 roads car communication 1, can be responsible for answering for most four elevators in same storied building room
Anxious intercommunication；
The quantity of the computer room extension set 2 is 1-255 platforms.
The elevator long distance wireless intercom system of the present invention, by UFH wireless data transmissions, GSM network, wireless voice communication three
The technology of aspect is combined, and computer room extension set is connect by UFH Radio Links with GSM hosts, then dials the electricity specified by GSM hosts
Number is talked about, is connected to duty room terminal, realizes intercommunication call, the present invention is without largely connecting up, without using a large amount of SIM cards, fortune
It seeks at low cost, can accomplish long-term line, real time phone call, stable quality is flexible and convenient to use, good environmental adaptability, has very
Good application prospect.
