Abstract

The invention discloses an embedded type self-powered wireless sensing system for highway health monitoring. The embedded type self-powered wireless sensing system comprises an upper computer and a lower computer, wherein the upper computer comprises a wireless data transfer radio station module, a visual interface, a computer and a data base, and the lower computer comprises a host machine and a slave machine. A control instruction sent by the upper machine is transmitted to the host machine, the host machine receives the instruction sent by the upper machine, analyzes the instruction and then sends the instruction to the slave machine, the slave machine executes a corresponding instruction and sends acquired data information to the host machine, and the host machine sends received data to the upper machine to finish transmission and execution of the instruction for one time. The embedded type self-powered wireless sensing system for the highway health monitoring has the advantages of being strong in adaptive capacity, high in reliability, strong in instantaneity, humanized in operation interface and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless sensing, and in particular relates to an embedded self-powered sensing system for expressway health monitoring. Background technique [0002] Transportation is the basis for the operation and development of modern economic society and the economic lifeline of the country, and expressway is an important carrier of transportation. However, with the passage of expressway operation time, increasing traffic volume, environmental changes, fatigue effects and material aging and other unfavorable factors, the expressway structure will inevitably face a decline in bearing capacity, resistance attenuation, damage accumulation, and reduced durability. And other issues. If we can know the health status information of the expressway in advance, and make appropriate adjustments, maintenance and repairs in time to prevent problems before they happen, the operation safety of the expressway will not be endangere...
