Elevator Five-party Intercom Gateway Typical Application

Typical Application 1

The elevator operation status collector can collect the real-time operation status of the elevator and control the elevator door opening/closing, etc.

The five-party intercom is installed in the car, machine room, control room, pit, and top of the car respectively, based on fiber optic and WIFI IP communication networks, two solutions. When personnel are trapped, they can make a one-key call for alarm and send information to the patrol personnel's mobile APP.

Typical Application 2

If the five-party intercom of Elevator A calls the center end through Gateway A, the IoT server receives the call and sends A's call request to the Dispatch Console, while notifying the matching Gateway C and Gateway A that their voice transmission IPs are consistent with each other to establish a call. If Elevator B also calls the center end during the call between A and C, and the IoT server cannot find another idle center end, the server notifies B to generate a line waiting tone on its own, and the server also notifies the Dispatch Console that B is calling. During the call between the two parties, only when the center end clears the alarm from A's end can both parties end the call.

If the Dispatch Console wants to proactively communicate with A, the server connects the IP voice channels of A and C.
