DTU wireless terminal device for communication network engineering

Abstract

The invention relates to a DTU wireless terminal device for communication network engineering. The wireless terminal device comprises a main body and two fixing blocks, two fixing blocks are respectively arranged at two sides of the main body, the frontage of the main body is provided with a cable interface, a data line interface, a power line interface, a switch and an indicator lamp; the back of the main body is provided with a line-connecting mechanism, a connecting rod and an antenna; the line connecting mechanism is provided with a plurality of line connecting units; through the adoption of the DTU wireless terminal device for the communication network engineering, an opening is formed on the top of the main body in the process of moving a glass plate to a clamping plate in a radiating mechanism, thereby emitting the heat in the main body to achieve the cooling effect and guarantee that the internal component is in a proper temperature environment; not only that, the model of an operation amplifier is OP07 in a voltage transformation circuit, the device has the features of being low in drifting, low in noise, hyper in stability, and wide in power voltage range, thereby improving the stability and the reliability of the voltage transformation circuit.

Description

technical field [0001] The invention relates to a DTU wireless terminal equipment used in communication network engineering. Background technique [0002] DTU (Data Transfer Unit) refers to the data transmission unit, which is a wireless terminal device specially used to convert serial data into IP data or convert IP data into serial data for transmission through a wireless communication network. Its hardware part mainly includes CPU control module, wireless communication module and power module, supports remote configuration, remote control, short message backup and alarm, etc., and is widely used in meteorology, hydrology and water conservancy, geology and other industries.

Problems solved by technology

[0003] During the working process of DTU, the internal components are in a closed environment. As the running time increases, the internal heat gradually accumulates and cannot be dissipated, resulting in the internal components of the equipment running in a high temperature environment, which affects the operation of the DTU. Efficiency is affected, and the life of internal devices is shortened. Not only that, but in the internal voltage transmission module of DTU, the existing voltage transmission circuit usually has poor stability, which is easy to cause drift, which reduces the reliability and reliability of the transmission circuit. stability
