I. Case Overview

With the development of the economy, the continuous reform of the heating system in China and the gradual expansion of the urban heating area have led to the problems of long heating distance, many heating points, and large heat loss during the heating process of the boiler plant. The requirements for thermal quality are getting higher and higher, which puts a lot of pressure on the operation and production management of heating enterprises. This requires heating enterprises to continuously increase management innovation and effectively improve the competitiveness of enterprises. It is not only an important part of management innovation, but also the only way to realize the healthy, stable and rapid development of enterprises.

At present, a heating company in Shunde, Guangdong, mainly supplies heat to local production enterprises. Previously, the management of heating valves has been using traditional methods. The valves cannot be monitored online, the flow data cannot be collected remotely, and the valve switches cannot To achieve remote control, people need to go to the site to operate, the efficiency is low, and the labor cost is very high. The company hopes to use an intelligent industrial monitoring system to realize the automation and scientific management of data collection and automatic control, reduce heat loss Improve the quality of heating, achieve the purpose of energy saving and consumption reduction and improve the overall management level.

MANTOO, as an industrial Internet of Things service provider integrating R & D and intelligent manufacturing capabilities in the Yangtze River Delta region, uses industrial Internet of Things technology and MTBE4-6-4A remote measurement and control system control cabinet according to the needs of heating companies to develop A remote heating online monitoring cloud platform system integrating data collection and automatic control functions has been developed. This product helps the factory solve the problems of serious heat loss and low management efficiency, so that the factory can implement visual management of flow data in various places and automatic valve control, which greatly improves the company's management level.

Ⅲ. System functions

-Information collection: Collect the data of each thermal node monitoring equipment (pressure meter, temperature meter, flow meter, etc.) and the status information of the switch valve.

-Remote control: remotely control the valves of pumps and other equipment to control the opening and closing of equipment.

-Intelligent alarm: monitoring data beyond the limit, on-site equipment failure, and send alarm information to the remote control terminal in real time.

-Graphical data interface: real-time monitoring of valve operation through pipeline heating flow chart.

-System management: all kinds of system parameter setting, user authority management, external data interface management.

Ⅴ. Introduction to hardware products

The MTBE4-6-4A Internet of Things remote measurement and control system control cabinet collects the flowmeter (pressure, temperature, flow) data of each thermal point and the status information of the switch valve, and directly uploads the real-time cloud view through the 4G network. If the field equipment fails, an alarm message will appear on the remote control end, and the pump and valve control will start at the same time.The control cabinet is mainly used to collect data from flowmeters and other sensors and upload it to the cloud platform, and at the same time detect the DI signal and control output according to the early warning value.

Ⅶ. Customer evaluation

In the traditional heating system, the quality of the heating system is not optimistic and the user experience is poor because of problems such as the heating distance, the heat collection point, and the large heat loss. Our traditional heating companies have also thought of many ways, and finally after using the remote heating online monitoring of Mantu Technology, many problems have been solved. The system effectively manages the valve, reduces the occurrence of stealing the valve and damaging the air leakage, etc. At the same time, there is no need for personnel to go to the site for service, which not only saves costs but also improves service experience, and has won unanimous praise from customers.
