Xinli Technology has been engaged in industrial-grade wireless communication products for many years and has rich project experience. Midea Group’s energy monitoring system is one of the cooperative projects. Real-time monitoring system, which is applied to Xinli Technology wireless products such as related wireless sensors, wireless management devices, wireless measurement and control devices.
The following is a brief overview of the energy monitoring system:
1. Project Background
Midea Group is a large-scale comprehensive modern enterprise group mainly engaged in the home appliance industry and involved in lighting appliances, real estate, logistics and other fields. It owns three listed companies and four major industrial groups. It is the largest white goods production base and exporter in China. one of the bases.
Energy is an important material basis for sustainable economic and social development. Strengthening energy management and improving energy utilization efficiency are important measures to improve the quality of economic operation, improve the environment and enhance the market competitiveness of enterprises. fundamental guarantee.
2. Project requirements
For a general factory of Midea Group, there are 7 branches (General Assembly Branch 1, General Assembly Branch 2, General Assembly Branch 3, Light Commercial Branch, Injection Branch Factory, Electronics Branch, Partial Assembly Branch) monitoring and monitoring Information analysis.
1. Real-time data collection and monitoring of on-site electric energy meters and various flow meters (such as compressed air flow, petroleum gas flow, oxygen flow, nitrogen flow, etc.) in each branch;
2. Realize the calculation, statistics and analysis of the electricity consumption, compressed air consumption, petroleum gas consumption, nitrogen consumption and oxygen consumption of each branch of each branch;
3. Realize statistical report function, real-time data and status display function, historical and real-time curve function, remote control function, management function, redundancy function;
4. The system is required to have good openness and can exchange data with other information systems.
3. Scheme design
The monitoring system is a layered distributed network structure, consisting of a three-layer structure of equipment layer, wireless network transmission layer, and monitoring layer. The equipment layer is mainly composed of flow meters and pressure gauges; the wireless network transmission layer is mainly composed of wireless data acquisition It is composed of transmission devices, wireless management devices and other equipment; the monitoring layer is composed of main equipment such as computers, monitoring software and network switches. The schematic diagram of the system structure is shown in the following figure:
Fourth, the host computer real-time monitoring
The following is the monitoring screenshot of Midea Group’s energy and gas monitoring system, which is an intuitive display of the data collected and transmitted by Xinli Technology’s wireless products on the host computer. Relevant personnel can understand the real-time status of each energy source through the collected data and deal with it in time.
