Abstract
At present, with the development of wireless communication and microcomputer control system, the design and construction level of long-span bridges in China are also improving. How to improve the durability of bridge structure has become a major scientific and technological problem in bridge design and construction. This paper studies a microcomputer control system of bridge dehumidification based on energy consumption optimization and wireless communication. It compares three kinds of dehumidification and anticorrosion methods of bridge engineering, namely, freezing dehumidification system, rotary dehumidification system, and hybrid dehumidification system. In the hardware design of microcomputer control system of dehumidification system, ATmega128 bit main control chip and aluminum designer are used to draw the power circuit. Then, the MCU program of the air dehumidifier is written, and the power of the air dehumidifier is controlled by the PWM signal generated by the timer 0 of the MCU. The air dehumidifier is divided into three tap positions corresponding to three duty cycles, and the power of the air dehumidifier is changed according to the input tap position.
Highlights
In the long history of development, all kinds of bridges have emerged, such as arch bridge, beam bridge, and suspension bridge [1]
The external air state point W is processed by the freezer to reach the state point O and heated by the heater to reach the state point N, which is fed into the main cable of the suspension bridge
The analysis shows that the hybrid dehumidification system can effectively dehumidify both the cold air and the hot and humid air and is the best choice in the feasibility
Summary
In the long history of development, all kinds of bridges have emerged, such as arch bridge, beam bridge, and suspension bridge [1]. People used bamboo strips, vines, and other natural materials to build simple suspension bridges. This paper explains and discusses the case from the main cable and cable-stayed bridge as well as points out the way of water intake and the reasons for the Wireless Communications and Mobile Computing two structures. On this basis, Jensen et al discuss the disadvantages of different wire rope concepts and make the different mitigation measures [5]. The controller is able to communicate with the single-chip microcomputer connected to the Internet
