The characteristics and application of industrial RTU

The full name of the remote terminal unit RTU is Remote Terminal Unit. It is a device for data collection and wireless transmission in a long communication distance and harsh environment. It has remote data collection, control and communication functions. It can receive operating instructions from the host computer and control the execution of the terminal. The mechanism moves to complete the "four remote" functions-telemetry, telesignal, remote control and remote adjustment.

RTU can also debug according to the environment of the monitoring site, user needs, and the way of obtaining electricity. It adopts wide voltage, high and low temperature resistance, moisture-proof, lightning-proof design, multi-interface access, city electricity, solar energy, and battery power supply to meet the needs of users. To achieve the functions of data transmission and remote debugging, control, and upgrade.

The characteristics of RTU are:

1. Longer communication distance;

2. Rich interfaces and small size can meet industrial needs;

3. Remote management, fault alarm reminder;

4. Multiple monitoring mechanisms, supplementary transmission of power outage data;

5. It is used for the collection, storage and transmission of field monitoring data for industrial applications such as smart gas, energy monitoring, heating pipe network, smart environmental protection, smart water conservancy, smart agriculture, pollutant monitoring, etc.

Industrial RTU has a wide range of applications. Below, Yuncheng will give you two common examples to understand the role of industrial RTU.

Energy field

The energy industry involves multiple links such as production, transmission, storage, measurement, use, and marketing, and its long transmission range and wide use range have resulted in high-quality, unified, and high-quality management, monitoring, and customer service. Efficiency will be very difficult. With the application of the Internet of Things, the application of RTU in the process of intelligent energy transmission has been put on the agenda. Through the Internet of Things technology, the original energy transmission network can be effectively transformed to make it intelligent.

Specific requirements may include:

1. Through the zoko-link industrial RTU, use the wireless automatic meter reading system to meet the information needs of urban energy sales and meter reading;

2. The monitoring of the energy pipeline network is achieved by setting up GRS data acquisition modules at major monitoring points such as gate stations, pressure regulating and measuring stations, and cooperating with video monitoring and leakage monitoring in key areas, and transmitting data through the RTU using wireless networks. Remote wireless monitoring of the pipe network;

3. The energy company establishes an enterprise-level management information system, including 0A, mail, and vehicle monitoring to improve the company’s overall informatization level.

4. According to the main pipeline transmission, gate station monitoring, storage station monitoring, pressure regulating and metering station, to-home transmission, meter reading, office, and marketing parts, they are described separately.

Agriculture field

The front-end sensor is responsible for monitoring the collection of agricultural information such as temperature, humidity, and light intensity. The light intensity sensor is placed above the crops to monitor the environmental light intensity in real time, and the light intensity of the crop growth environment can be grasped in time; the level of the environmental temperature directly affects the growth rate of the crops. Developmental situation. The collected data is transmitted to the control center through RTU. The control center will process the received data and store it in the database, conduct a summary analysis based on the collected information, and combine the expert decision-making system to issue feedback control instructions to find and solve problems in a timely and accurate manner, and guide agricultural production.

Through the network, producers and technical researchers can monitor the collected agricultural information anytime and anywhere, and track crop growth in real time. The technicians in charge of crop production will formulate reasonable cultivation strategies (such as increasing temperature, increasing humidity, and watering) according to the actual growth conditions and actual needs of their crops, and issue corresponding instructions. It will respond to back-end instructions, such as adjusting light intensity, irrigation time, herbicide concentration, and so on.

The zoko-link industrial RTU has corresponding applications in all walks of life. In addition to the above-mentioned fields, there are also such as water conservancy, environmental protection, pollutant data monitoring, etc., industrial RTU has an indispensable role.
