systemOverview
The safety of the elevator is always put in the first place, and a perfect elevator five-party intercom system (also known as the elevator emergency distress system) is an integral part of ensuring the safe operation of the elevator. Once the elevator fails, the personnel trapped in the elevator can contact the management center or the outside world through the elevator intercom system, so as to rescue the trapped personnel in a timely manner, ensure the safety of each passenger's life, and create a safe elevator environment for the elevator personnel is the greatest significance of the system.
IP networked visual five-party intercom system is a specially designed product according to the "Elevator Manufacturing and Installation Safety Code" GB7588-2003. This system is an all-digital two-way intercom system. The intercom system is the use of TCP IP pure digital coding technology, standard SIP voice, ONVIF** protocol, echo reduction technology and other communication technology, so that the whole system can be two-way communication, that is, the car, the car roof, the pit, the machine room extension can call to the management machine, and the management machine can also call the elevator extension, the elevator communication system can achieve two-way call between the equipment. The system adopts optical fiber or UTP5E networking to ensure high call quality.
System composition
Management host: The property management office uses, accepts and processes the call calls and distress information of the car, car roof, pit, computer room and other extensions. Multiple ladders share one unit.
Networked equipment: networked use, used for the connection of signals between elevators to the management center. If the traditional Ethernet network is used, the equipment includes: network cable, optical fiber, optical fiber transceiver, and switchIf you use EPON to network, the devices include network cables, optical fibers, ONUs, OLTs, optical splitters, and switches.
Machine room extension: the extension is the main communication equipment in the car, the car roof, the pit, the machine room phone and the management host, in addition to having the function of the elevator personnel to ask for help outside in case of emergency, the internal communication system can also bring convenience to the elevator maintenance personnel. The extension can be one ladder, two ladders, three ladders, and four ladders, depending on the actual situation.
Elevator telephone: There are two kinds of telephones in the car, car roof, pit, and computer room, and there are two types: handle and hands-free type. They are indispensable equipment to ensure the daily operation of the elevator. One phone in the car, one on the top of the car, one in the pit, and one in the computer room.
Emergency power supply: Emergency power supply is an indispensable equipment in elevators. When the elevator encounters a power failure, the emergency power supply not only lights up the emergency light in the car and starts the alarm siren, but also provides emergency power to the elevator communication system, so that the trapped elevator personnel can call for help to the management office and the machine room duty personnel through the emergency call button on the car host in the lighting environment. One ladder and one ladder.
3.Introduction to the superior performance of this product
1. It adopts TCP IP network transmission, which has strong scalability, and shares the same network with other network systems such as monitoring, and has low cost.
2. Unique echo cancellation technology, duplex call voice is clear, no side tone, no distortion.
3. The system automatically inspects, the equipment maintenance is simple, the judgment is intelligent, and the equipment failure is actively prompted.
Fourth, the management host adopts the full Chinese caller ID mode, the staff can accurately and easily identify the location of the elevator for help or call, and can automatically record the time and location of the call.
5. Problems in any subsystem (elevator) will not affect the use of other elevators.
Sixth, the video intercom system can monitor the current affairs of any elevator in the system at any time, and the scene is clear at a glance when the car calls for help.
