RTU supports multiple communication methods, high-speed network access

With the development of science and technology, RTU technology is increasingly applied in various fields. Compared with the traditional programmable controller (PLC), RTU has excellent communication capabilities and larger data storage capacity, especially suitable for harsh temperature and humidity environments, and provides more complex calculation functions. RTU is a typical application in the field of environmental monitoring, which can collect, save and transmit field data, and can also realize the functions of remote control, remote signaling, and remote measurement of equipment.

1. Choose RTU in the field of environmental monitoring

Environmental monitoring sites are often located in industrial sites with harsh environments. Products used must have a special protection level, and network security must be fully considered. Although the use of industrial computers may simplify project implementation in some aspects, it is not cost-effective. As a professional industrial product, the data acquisition and transmission instrument based on RTU technology is more integrated in installation and has low environmental requirements; it adopts embedded operating system, has higher network security performance, and is suitable for long-term operation and maintenance-free monitoring system use.

Second, the function of RTU

Support multiple communication methods, high-speed network access

Support 4G/3G/2G wireless cellular network.

Ultra-low power design, rich working modes

Multi-level sleep and wake-up modes, the power consumption is much lower than similar products in the industry; multiple working modes: including self-report, query, and compatible.

Standardized MOBUS protocol

The remote measurement and control terminal transmission supports multiple protocols; self-defined protocol and Modbus protocol to meet the needs of different application environments.

Efficient management and transmission security

Designated IP access, multi-layer encryption transmission guarantees the security and accuracy of data, and the data transmission reaches financial level standards.

Integration of collection and transmission, visualized data

RTU local configuration mode supports serial port configuration. It integrates the functions of environmental monitoring data collection, storage, display, control, alarm and transmission.

Intelligent wake-up protection mechanism, stable transmission

Intelligent software wake-up and hardware power-off restart mechanism, the device automatically resets to ensure normal operation; disconnected and reconnected, data reissue, stable and reliable transmission without packet loss.

Easily realize remote management, saving manpower and material resources

Equipment failure alarm, support remote parameter configuration, provide powerful central management software, remote upgrade.

Three, the typical application of environmental monitoring RTU

RTU can be used to collect and store the data of various types of monitoring instruments and meters, and can complete the data terminal unit with the upper computer data transmission function, and has a separate data processing function.

RTU is the connection terminal equipment of field instrument and host computer system. It collects monitoring data and status information of monitoring instrument through digital channel, analog channel and switch channel, and transmits the data and status to the host computer through the transmission network; the host computer transmits through the transmission network. The network sends control commands, and the RTU controls the monitoring instruments according to the commands.
