The two-way transparent transmission of 4G network data means: a wireless terminal device that converts serial port data into IP data or converts IP data into serial port data and transmits it through the wireless communication network. Referred to as 4G DTU, most DTUs currently on the market use two-way transparent transmission, that is, whatever data is collected is what is sent to the host computer. In the same way, whatever data is sent down by the host computer is what data is sent down to the device. The same is true for Zongheng Intelligent Control 4G DTU (ZHC4012). It is a two-way transparent transmission.
Application of 4G DTU in remote meter reading
Through the intelligent control of 4G DTU by smart meters, computer technology, communication technology, etc. are used to form an electric meter with smart chips (such as CPU) as the core and functions such as electric power measurement and timing, billing, communication with the host computer, and power consumption management. . The remote automatic meter reading system realizes automatic reading of electricity consumption data, eliminating all the disadvantages of manual operation. Users’ electricity consumption data can be directly entered into the computer management system of the electricity business, and electricity management personnel can monitor electricity consumption at any time. Through the 4G DTU of Zongheng Intelligent Control, automatic collection of meter data, effective statistics of electricity consumption of each meter, automatic payment, etc. can be realized.
Application of 4G DTU in hydrological monitoring
Through metering and measuring equipment and 4G DTU, the water regime, rain regime, flow rate, and video image information of the rivers and reservoirs where the hydropower station is located can be monitored, and various monitoring contents can be analyzed, stored, and early warning managed. This provides relevant information services to staff in various functions to facilitate the management of each hydropower station and improve work efficiency. The functions of the automatic monitoring station include data collection, data display, parameter setting, reporting function, query and download, video transmission, communication and transmission, data storage, clock calibration, self-diagnosis and self-recovery, and lightning protection functions.
