detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings, which is an explanation of the utility model rather than a limitation.

The utility model, as shown in Figure 1, adopts the technical framework of the Internet of Things, and is used to monitor the urban elevator between the monitoring center and the IPC upper computer, and uses a wireless network covering a city to communicate, and the IPC upper computer and the PLC lower computer Use long-distance wireless communication to communicate with each other to realize remote access and data sharing of PLC lower computer data. Preferably, the wireless communication device DTP_S09F_GPRS is used.

The utility model is used to monitor the monitoring center of urban shopping malls and community elevators. Its communication network adopts a wireless communication network covering the whole city. The monitoring terminal is a PLC lower computer, which is mainly responsible for the real-time monitoring of elevator operation. During the period, remote access and data sharing are carried out through the IPC host computer.

The monitoring results are transmitted by the IPC host computer to the monitoring center through the wireless network, and the monitoring center can know the operation status and prompt alarm information of the city elevator at the first time, and can check the historical records of elevator maintenance and the elevator prompt alarm information. Records such as accuracy and troubleshooting time.
