Description
Technical Field
The invention belongs to the technical field of visual intercom, and particularly relates to a subway visual intercom system.
Background
The existing elevator intercom system in the subway station is generally directly equipped by an elevator dealer, and the intercom system of the elevator is almost the same as that of other elevators (such as elevators for residential buildings) and has no great difference. The elevator system can meet the intercommunication between the interior and the exterior of the elevator in a common use scene, and can be used in rail transit use scenes such as subway stations, but still has the problems that: the traditional intercom system has no video function, and when a trapped person presses down an alarm key, a vehicle control room worker cannot visually know the situation of the trapped person and can only talk back through voice. The monitoring function in the existing elevator is generally realized through the arranged camera and the network, but the monitoring function is two sets of systems, and the monitoring function does not belong to an intercom system, the intercom and the monitoring are respectively realized, so that the monitoring function not only needs to be respectively arranged, but also is very inconvenient to use, and if network problems or other problems are met, the problem of asynchronization can occur. Therefore, a monitoring system is generally not equipped in the existing subway car control room, when the elevator is trapped, on-site rescue workers cannot visually know the situation of the elevator in real time, the elevator is generally communicated through a handheld intercom system, inconvenience is not only brought, difficulty is also caused for rescue, and particularly, the situation under the visible environment in the car is not known, serious influence is brought to the rescue mode, and even a certain rescue risk exists.
The existing elevator intercom system in the subway station is only a voice intercom system generally, and the voice is transmitted by adopting analog signals, so that the interference is easy to happen, and the intercom is not clear. When the trapped person presses the alarm key, the person in the control room can only communicate with the trapped person in a voice mode, and the situation of the site cannot be judged visually and clearly, so that the rescue cannot be carried out accurately and timely.
