Shulou(Shulou.com)06/01 Report--

The full name of the remote terminal unit RTU is Remote Terminal Unit, which is a kind of equipment for data acquisition and wireless transmission in a long communication distance and harsh environment. It has the functions of remote data acquisition, control and communication. It can receive the operation instructions of the host computer, control the action of the terminal actuator, and complete the "four remote" functions-telemetry, remote signal, remote control and remote adjustment.

RTU can also be debugged according to the environment of the monitoring site, the needs of users, the mode of power acquisition and so on. It adopts wide voltage, high and low temperature resistance, moisture-proof, lightning-proof design, multi-interface access, municipal 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. Long communication distance

2. Rich interfaces and small size can meet the needs of industry.

3. Remote management, fault alarm reminder

4. Multiple monitoring mechanism and supplementary transmission of power outage data.

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

Industrial RTU has a wide range of applications. Here are two common examples to show you the role of industrial RTU:

Energy field

The energy industry involves many links, such as production, transmission, storage, measurement, use, marketing and so on, and its transmission range is long and wide, so it is very difficult to achieve high quality, unification and high efficiency in management, monitoring and customer service. With the application of the Internet of things, the application of RTU in 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. The wireless automatic meter reading system is used to meet the information needs of urban energy sales and meter reading through the RTU of the industry.

2. The monitoring of the energy pipe network, by setting up the GRS data acquisition module in the main monitoring points, such as gate stations and surge metering stations, and cooperating with the video surveillance and leakage monitoring in key areas, the data is transmitted through the wireless network through RTU, so as to realize the remote wireless monitoring of the pipe network.

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

4. Describe separately according to the main pipeline transmission, door station monitoring, storage station monitoring, surge metering station, door-to-door transmission, meter reading, office and marketing parts.

Agricultural field

The front-end sensor is responsible for the collection of agricultural information such as temperature, humidity and light intensity, and a light intensity sensor is placed above the crops to monitor the environmental light intensity in real time, which can grasp the light intensity of the crop growth environment in time; the environmental temperature directly affects the growth speed and development of crops. The collected data is transmitted to the control center through RTU. The control center stores the received data in the database after processing, summarizes and analyzes the collected information, and sends out feedback control instructions combined with expert decision-making system to find and solve problems timely and accurately, and guide agricultural production.

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