Method for establishing conversation through multi-monitoring center digital conversation system mixed line

Abstract

The invention discloses a method for establishing a call through a mixed line of a multi-monitoring-center digital call system. A call system of the method comprises the following devices: a main monitoring center host, an auxiliary monitoring center host, a machine room host, a car host, a car roof host and a pit host. A communication module, a multi-party call service module and other modules are arranged in each device; and the main monitoring center host maintains a relation table of domain IDs and IPs of each machine room host and the auxiliary monitoring center host, a unique identifier of the wireless cloud and a communication line type according to the basic communication parameters. The invention further provides specific steps of the method for establishing the call through the multi-monitoring-center digital call system mixed line. According to the development method for realizing communication by supporting multiple monitoring centers and wired and wireless hybrid access provided by the invention, the requirement that an elevator park-level call system supports multiple monitoring centers and can support wired and wireless hybrid free access can be met, and the convenience of field installation and deployment, later maintenance and use is greatly improved.
