Description
The present invention relates to a kind of elevator long-distance monitorng technology, particularly a kind of elevator remote monitoring system that carries out remote information collection, professional intellectual ability fractional analysis processing and information transmission by telephone network.
In recent years, along with China's rapid economy development, the skyscraper emerge in multitude, elevator obtains more and more widely application as the desirable instrument of taking, and the elevator safety problem of Chan Shenging is also more and more thereupon.Because the present employed elevator of China generally lacks the alert service device, when elevator broke down, the repair and maintenance personnel often can not in time, accurately recognize the failure message of elevator, and the life security of elevator passenger is subjected to very big threat.There is following point in existing elevator faults warning:
1, elevator breaks down, and repair and maintenance unit only receives user's signalling trouble can know that just speed of response is slow;
2, require the on site maintenance personnel that abundant service experience must be arranged, just can find out the trouble point of elevator, no automatic diagnostic function;
When 3, elevator can not move, just knowing had fault, can not predict, forecast elevator faults;
4, elevator maintain and protection unit, every month regularly the scene of sending someone check elevator running condition, just can obtain the elevator run book, no real time monitoring function;
5, the passenger is trapped in the elevator, does not often know how to cry for help or to whose emergency.
The object of the present invention is to provide a kind of simple in structure, integrated level is high, speed of response is fast, establishment is convenient, highly intelligentized elevator remote monitoring system.
The technical solution that realizes the object of the invention is: a kind of elevator remote monitoring system, it is characterized in that monitored elevator being linked in the Control Network by telephone network, possess the elevator monitoring device that information acquisition, information intelligent analyzing and processing and information transmits and be arranged on the controlled elevator, the elevator management terminal of receiving a crime report is connected with public telephone network.
Purpose of the present invention can also connect the exchange of distribute data path and realize between public telephone network and monitor.
Purpose of the present invention can also connect the concentrator of concentration of transmissions data and realize between exchange and monitor.
Principle of work of the present invention is; The elevator monitoring device is monitored elevator operation in real time, and when reporting to the police appears in elevator (the manual warning and auto alarm), the elevator monitoring device is put through the telephone number of the terminal of receiving a crime report automatically, by public telephone network, sends breakdown signal to the terminal of receiving a crime report.Terminal is telephone set or mobile phone if receive a crime report, and then alarm message transmits with speech form; Terminal is a computing machine if receive a crime report, and then alarm message transmits with double-tone frequency, FSK or MODEM form, after computing machine is received alarm message, demonstrates the position at fault elevator place immediately on electronic chart, shows the archives material of faulty condition and elevator simultaneously.When manually reporting to the police, the computer operator is by microphone and audio amplifier, directly with lift car in stranded passenger's conversation, comfort passenger and instruct some first-aid methods.
Calculate function and put through the telephone number of elevator monitoring device automatically, monitor elevator operation in real time, on screen, dynamically demonstrate information such as elevator parking station, service direction, switch door state, faulty condition; Can read the failure message that the elevator monitoring device is write down, fault is predicted, forecast; Can also give elevator monitoring device transmitting control commands, elevator is carried out Long-distance Control (as: operations such as shutdown, flat bed, switch door).
The present invention compared with prior art, its remarkable advantage is:
1, system architecture is simple, integrated level is high, speed of response is fast;
2, the elevator monitoring body is long-pending little, in light weight, power consumption is little, is directly installed in the elevator control cabinet, and the line of connecting with the mains, signal wire (SW), telephone wire can use, and has manually and automatic dual warning function;
3, monitor elevator running condition in real time, the emergency elevator is out of service when occurring, the running state that the maintainer can access elevator in the information storage body before being out of order, thus can judge trouble point and out of order reason fast, shorten maintenance time;
4, information acquisition module has four kinds of acquisition component, can be applicable to the elevator of the various models of domestic and international various manufacturer production.
5, the information and the elevator monitoring device working parameters such as telephone number of city, elevator place, street, mansion, elevator archives material, the department that receives a crime report directly are input to the elevator monitoring device with handwriting pad when being on-site installation, and voice suggestion is arranged during operation;
6, information transfer module has a plurality of transfer members, and the department of receiving a crime report can receive alerting signal with multiple communication facilities, reduces the investment of the department that receives a crime report;
7, a mansion has the multi-section elevator, only needs a telephone wire just can realize decentralised control, centralized management to all elevators in the mansion, thereby makes system have high speed of response;
8, have remote monitoring elevator operation, read failure recorded information, fault is predicted, is forecast.
