Embodiment 1

[0014] When the present invention is applied to only one intercom button on the control panel of the car, the entire communication system of the present invention is divided into two parts, the internal intercom and the external local call rescue (as shown in the accompanying drawings), and the two parts share a set of speakers and microphones. The intercom button is connected to all machine room extensions, car top extensions, pit extensions and the host computer in the duty room through two buses, and communicates with the outside local network through the local gateway. The local gateway is provided with more than one outside rescue telephone number. Call for help in the car by means of automatic circular dialing. When the intercom button is pressed once, the external call for help will be connected to the host in the duty room. When no one answers the host in the duty room for more than 30 seconds (the length of time can be set arbitrarily), the communication system will au...

Description

technical field [0001] The invention belongs to a communication system, in particular to a special communication method for elevators. Background technique [0002] In 2004, China's State Bureau of Technical Supervision issued a new version of "Safety Code for Elevator Manufacturing and Installation" (GB7588-2003), requiring that all elevators manufactured after January 1, 2005 must be equipped with a five-party communication system, that is, in the duty room, car The five-party communication between the car, the machine room, the car roof and the pit is realized, but almost all existing elevator manufacturers use a simple intercom system. When the elevator is trapped due to reasons such as failure or power failure, and the duty room personnel are not on duty, the trapped personnel in the car often have no way to call and are trapped for a long time. Because the duty room was unattended, reports of staff working late at night or residents who returne...
