Wireless data collection has more and more widespread applications in production and life, such as intelligent meter reading in residential areas and real-time monitoring of equipment operation in industrial sites. As a low-power wide-area network communication technology, LoRa realizes the requirements of both long-distance and low-power consumption for the Internet of Things, making LoRa technology applied in more and more fields.
LoRa DTU is a data transmission terminal designed for long-distance, multi-node applications. It is based on LoRa modulation spread spectrum technology and uses the LoRa network to provide users with wireless data transmission functions.
The LoRa DTU independently developed and produced by Zongheng Intelligent Control has rich interfaces and provides a standard RS485 interface that can be directly connected to serial devices. In addition, it also provides digital input and output and analog input.
The LoRa DTU has been carefully adjusted by engineers, with a measured communication distance of up to 8Km, which perfectly solves the problem of ultra-long-distance communication with small data volumes in complex environments, and provides powerful wireless communication networking guarantees for IoT applications in various industries.
The LoRa DTU uses forward error correction technology to add redundant information to the data sequence to be transmitted. Error symbols injected during the data transmission process will be corrected in time at the receiving end. Combined with the four-channel conflict detection optimization technology, it solves the problem of concurrent packet loss of node data in actual projects and greatly improves the link robustness.
The LoRa DTU adopts a user-friendly design. Users do not need to understand the complex data transmission process and can send and receive wireless data through simple configuration. LoRa has excellent low power consumption and long-distance transmission performance, and is suitable for use in some long-distance, small-bandwidth situations. It can be widely used in remote meter reading, power monitoring, environmental monitoring, smart oil fields, agricultural informatization, industrial automation, etc. field.
