Embodiment Construction
[0089] see figure 1 , the system is mainly composed of three parts: the front-end acquisition module (lower computer), the communication system, and the background management control module (upper computer). The host computer is composed of a general-purpose PC computer (desktop or notebook). The upper computer and the lower computer are connected through a communication system. The lower computer includes a measurement module, and the measurement module is respectively connected with the communication system and the splitter, and the splitter is connected with the sensor. The lower computer is responsible for collecting real-time measurement data of steel string sensors; the communication system is responsible for providing information and data transmission channels for the upper and lower computers through various communication methods; the upper computer is responsible for data processing, storage and control of the front-end acquisition module.
[0090] The system can be...

Abstract
The invention relates to a civil engineering structural remote health monitoring system. The system can help know health state of civil engineering structure timely, protect safety of measurement technicians, decrease labor intensity and monitoring cost, shorten working time, increase efficiency, and realize multipoint synchronous monitoring. The system consists of an upper computer and a lower computer connected by a communication system. The lower computer comprises measurement modules which are connected with the communication system and a deconcentrator respectively, and the deconcentrator is connected with a sensor. The measurement modules comprise a single-chip computer; the single-chip computer is respectively connected with a pulse forming circuit, an amplified-filter circuit, a keyboard, a memory, a clock circuit, a communication circuit, a display screen and a temperature sensor. The single-chip computer, the pulse forming circuit and the amplified-filter circuit are all connected with the deconcentrator.
Description
1. Technical field: [0001] The invention relates to a structure monitoring system, in particular to a remote monitoring system for the health status of civil engineering structures. 2. Background technology: [0002] In large-scale civil engineering projects such as roads, bridges, and tunnels, remote and ultra-remote monitoring of engineering health status has always been an effective means that the industry dreams of. Especially with the rapid development of the national economy and the construction and development of the west, there have been many unprecedented long, large, high, deep, special and dangerous projects. An important part of these project constructions is the monitoring of the mechanical state of engineering structures , such as pressure, strain, distance, temperature, humidity, smoke, etc. Due to the poor geographical location and environment of these projects, for example, high altitude, thin air, low oxygen content, low temperature, etc., it has brought g...
