Nine typical application examples of wireless sensor technology for the Internet of Things

2025-04-03

With the continuous improvement of the Internet of Things wireless sensor technology, it is more and more widely used, mainly used in petrochemical, electric power, industrial manufacturing, medicine, agriculture, aquaculture, municipal administration and other fields, which not only improves work efficiency, but also reduces production costs.

1. Wireless monitoring of EMS energy data

For a main plant of Midea Group, there are 7 branch plants (the first branch of the final assembly, the second branch of the final assembly, the third branch of the final assembly, the light commercial branch, the injection branch, the electronic branch, and the partial assembly branch) under the monitoring and control Information analysis.

1. Realize 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.) of each line body of each branch;

2. Realize the calculation, statistics and analysis of electricity consumption, compressed air consumption, petroleum gas consumption, nitrogen consumption, oxygen consumption, etc. of each line body of each branch;

3. Realize statistical report function, real-time data and status display function, history 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.

2. Water level monitoring of underground pipe ditch

In order to ensure the safe operation of the entire park in Shanghai Disneyland, scientific and thoughtful monitoring and management of the water supply and drainage pipeline network is required.

1. There are a total of six points that need to monitor the water level of the underground pipe trench;

2. When the water level exceeds the limit, upload the signal to a computer or mobile phone.

3. Wireless monitoring of pressure, flow and temperature of power plant pipe network

The wireless monitoring of pipe network pressure, flow and temperature in Guangdong Luoding Power Plant mainly monitors the pressure, flow, temperature, valve opening and other parameters of the pipe network, and opens and closes the valves when needed. The system is composed of a monitoring center, a communication network, and a measurement and control terminal.

The data collection terminal of each pipe network monitoring point can monitor and collect parameters such as temperature, pressure, flow, etc. At the same time, it has the remote control function, which can carry out the open and close scheduling and display of pipe network valves. The data is stored in the database for the control center and relevant departments to analyze and make decisions, and can be stored for at least two years to improve work efficiency.

4. Intelligent environmental monitoring of agricultural greenhouses

Intelligent environmental monitoring requirements for agricultural greenhouses of Shenzhen Tsinghua Research Institute:

1. Four greenhouses, each monitor two channels of air temperature and humidity, two channels of soil temperature and humidity, one channel of carbon dioxide concentration, and one channel of light intensity;

2. Display in three places: touch screen (the monitoring PC is far away, wireless transmission is recommended); LED screen displays related monitoring data, about 10 meters away from the host;

3. The monitoring PC installs the upper computer software and displays the monitoring data interface.

5. Wireless monitoring of livestock and poultry breeding environment

Wireless real-time monitoring of the environment of chicken farms in Weifang, Shandong. According to the breeds and different growth stages of the chicken farms, the temperature and humidity, oxygen, ammonia, hydrogen sulfide, carbon dioxide concentration, light intensity, water consumption, electricity consumption, etc. of each chicken house are monitored data.

Real-time collection of on-site sensor signals, remote monitoring of the operation of the chicken coop, data collection, analysis, and early warning and alarm in the monitoring background, the data is formed into a historical database, and historical curves and data reports are generated.

6. Real-time monitoring of laboratory temperature, humidity and pressure difference

Requirements for real-time monitoring of temperature, humidity, and pressure difference in BGI's genetic laboratory:

1. Real-time monitoring of laboratory environment temperature, humidity, and pressure difference, while transmitting the monitoring data to the monitoring center;

2. The temperature of the freezer inside the laboratory is monitored in real time, and the monitoring data is wirelessly transmitted to the monitoring center;

3. The on-site acquisition device and detection device adopt wireless data transmission, with simple wiring and convenient installation;

4. Set the temperature and humidity upper and lower limit sound and light alarm, the monitoring software interface directly displays, no need to add a hardware alarm, you can independently perform sound and light alarm instructions on the temperature, temperature, humidity, and pressure difference on the actual screen, and send it through the SMS modem Alarm information to the mobile phone of designated personnel;

5. Equipment output standard Modbus protocol and TCP/IP interface;

6. It can be seamlessly connected with the company's internal network, and the monitoring data can be accessed through the WEB page, as well as the remote monitoring server data of the external network, and the monitoring parameters in the laboratory can be remotely monitored anytime and anywhere;

7. Historical data storage, report printing, data curve graphs, etc.

7. Monitoring the operation status of the inverter

Requirements for monitoring the operation status of the inverter of Ningbo Limeng Technology:

1. Through wireless transmission, monitor the running status of the inverter (with RS-485 interface) and display it on the PC interface;

2. Control the start and stop of the inverter, and time the running time;

3. Check the input and output frequency of the inverter; the input frequency can be set;

4. Display the operating status of the inverter;

5. A pc can monitor the operation status of all frequency converter equipment in the workshop.

There are more than 100 frequency converter equipment on the customer workshop site, and the operation status monitoring system of 5 frequency converters is built in advance.

8. Wireless monitoring of water meter collective reading

Requirements for wireless monitoring of water meters in Chiwan Container Terminal:

The system adopts the mature MODBUS protocol, collects real-time water consumption, and transmits the data to the monitoring center through a wireless management device. After background processing, the color, sound and SMS alarm system is triggered to notify the administrator anytime, anywhere.

9. factory gas wireless monitoring

Huawei factory wireless TVOC gas monitoring requirements:

1. The clean room is divided into two layers, each layer is 500*500m, and the height is 6m;

2. 15 TVOC wireless gas sensors are arranged on each floor, with a total of 30 detection points;

3. Upload to the general management device through wireless transmission, and then display on the upper computer, supporting the upper computer software.
