The remote monitoring system of central air conditioning is mainly composed of remote monitoring computer and on-site monitoring system. The remote monitoring computer is connected to the site monitoring system through the Internet network and is the interface between the user and the site equipment. It mainly obtains the remote equipment status from the site monitoring system, analyzes and processes the remote equipment parameters and data, and then issues control commands and input parameters to the site monitoring system through the Internet network, so as to achieve remote monitoring of the central air conditioning.

The site monitoring computer is mainly responsible for sending control commands to the site controller, monitoring the status of the equipment and making necessary analysis, and then feeding these states to the remote monitoring computer through the Internet network. The site controller is mainly responsible for collecting the operation status and data of each control node, and then transmitting them to the site monitoring computer or industrial cloud server through the industrial intelligent gateway after aggregation and pre-processing, which can also control each node to take corresponding actions through the control commands sent by the site monitoring computer.

Central air-conditioning remote monitoring system can achieve the function：

1、Air conditioner energy efficiency analysis: It analyzes the operating energy efficiency of sold air conditioners, allowing owners and manufacturers' managers to grasp the operating energy efficiency of equipment in real time. The analysis results include various energy consumption reports, energy consumption summary report, daily load curve report, energy consumption ranking report, energy consumption ratio report, energy consumption year-on-year and ring comparison report, energy consumption cost summary report, and energy consumption cost ranking report.

2、Equipment management: In response to the problem of "more maintenance personnel are needed as the number of products sold increases" encountered by air conditioner manufacturers, the remote operation and maintenance system is designed to manage the equipment data of the air conditioners themselves. It includes the entry, modification and query of equipment information; automatic recording, query and export of equipment operation data; equipment search and query. Equipment maintenance record entry and query; maintenance schedule setting and work order process departure; equipment abnormal maintenance process triggering; equipment operation status report (single machine of the month / history of total running time, single machine of the month / history of total normal stop time, single machine of the month / history of total failure time, single machine of the month / history of total cycle stop time, single machine of the month of the main failure schedule, single machine of the month / history COP).

3、Remote commissioning of equipment: For customized units, the remote operation and maintenance system realizes the function of uploading and downloading the controller program remotely, so that the equipment commissioning personnel of manufacturers can modify the PLC program at any time, saving a lot of time for going out for commissioning.

4、Alarm management: When monitoring abnormal data of equipment and equipment network dropped the system can actively push alarm SMS to customers and factory managers.

5、User management: The system realizes multi-role authority control for manufacturers' management, manufacturers' after-sales personnel, owners and temporary users at all levels.
