Problems solved by technology

[0005] Communication technology plays a key role in the elevator remote monitoring system. At present, most of the communication methods for elevator remote monitoring are remote calls through the serial port. Modem dialing is used to dial the central end system through the public telephone network. The call fee is high, and the building The management center in the building generally cannot obtain the operating status information of the elevator. Even if some information can be obtained, the microprocessor is networked through CAN, RS-232, RS-485 and other buses, but the effective radius of this network is relatively limited. There are also fewer communication protocols, and are generally isolated from the Internet

Embodiment Construction

[0023] Such as figure 2 As shown, an elevator remote monitoring system based on the Internet is composed of an elevator controller 6, a terminal 7, a monitoring center 9, and a communication subsystem between the monitoring center 9 and the terminal 7, wherein one monitoring center 9 corresponds to multiple Terminal 7, one terminal 7 monitors several elevator controllers 6, the communication subsystem is composed of Internet network 8 or PSTN network 11 and Internet network 8, and terminal 7 collects elevator controller 6 data through RS422 serial port communication interface and accesses the Internet The network 8 or the Internet network 8 through the PSTN telephone network 11 communicate with the monitoring center 9 connected to the other end of the Internet network 8 . The elevator monitoring center 9 is also connected with a database server 10 .

[0024] The PSTN network 11 is only used as an alternative network for data transmission communication.

[0025] The Internet...

Abstract

A remote monitoring system of elevator based on Internet network comprises elevator controller, terminal, monitoring center and communication subsystem. It is featured as using embedded processor as core of terminal external - connected to SDRAM, FPGA, FLASH, etc; using embedded Linux system as operation system of terminal connected to Internet network for communicating to monitoring center at the other end and forming communication subsystem by Internet network.

Description

technical field [0001] The invention relates to a network-based monitoring system, in particular to an elevator remote monitoring system based on Internet network communication. Background technique [0002] Elevator remote monitoring means that the elevator remote monitoring center monitors the running and on-site elevators through a communication method, and collects the elevator's operating data and alarm status. figure 1 Shown is the topology of a typical elevator remote monitoring system, including terminal acquisition subsystem, communication subsystem, and monitoring center subsystem, specifically including elevator controller 1, terminal 2, communication circuit 3, monitoring center 4, and database server 5. [0003] Among them, the terminal is a device that monitors multiple elevator controllers that are relatively close to each other, and it is an important part of the terminal acquisition subsystem. The terminal collects the status of multiple elevator controller...
