In the Internet of Things era where things are connected, the demand for data transparent transmission is growing day by day. From a technical perspective, wireless transmission technologies with obvious advantages such as 4G, NB-IoT, WiFi, Ethernet, and LoRa have become the mainstream wireless transmission methods for the Internet of Things. Modules that rely on these wireless transmission technologies can achieve the same length and content of the sender and receiver data without any processing of the data. It is equivalent to an invisible data line or serial port line and is widely used in environmental protection, agriculture, and industry. , meteorology, geology and many other fields.
Что такое прозрачная передача данных?
Data transparent transmission refers to a data transmission method that has nothing to do with the medium, modulation and demodulation method, transmission method, and transmission protocol of the transmission network. Data transparent transmission means transparent transmission of data. It means that during the data transmission process, this set of data will not be changed in any way through wireless means, as if the transmission process is transparent, while ensuring the quality of the transmission and remaining intact. to the final recipient.
Specifically, it can be understood as: Suppose there is data s that needs to pass through a network. The entrance of this network is a and the exit is b. When the data s reaches a, a is responsible for encapsulating s. For example, s is IP data, and a uses the second layer. Format encapsulation, throughout the entire network, the second layer is used for transmission. At exit b, the encapsulation is unwound and restored to the original IP structure of s. For s, through this network, none of its structure and data has been changed. Therefore, for s, the network passing through is “transparent”, which is transparent transmission.
In order to meet the current growing demand for data transmission, Zongheng Intelligent Control, as a provider of IoT products and application solutions, focuses on the research and development and production of 4G/GPRS/NB-IoT/LoRa/Ethernet DTU, RTU, modules, wireless gateways, industrial Industrial Internet of Things equipment such as routers and serial servers are based on wireless transmission technology to realize functions such as wireless transparent transmission and remote control. They can be widely used in power systems, industrial monitoring, traffic management, environmental monitoring, meteorology, water conservancy, coal mines, and petroleum. , new energy and other industries, providing strong support for the communication network and wireless transmission of the project.
