温度监测在土木建筑施工、储粮仓库、智能楼宇、空调系统以及其他工农业生产中有着广泛的应用。传统的测温方法是在各监测点布置温度探头，由专人每天定时采集各点的温度数据，再输入电脑保存，并生成温度、应力的变化曲线和测试报告，也有一些是通过数据采集箱采集温度和应力数据，然后通过电缆上传电脑做进一步的数据处理。

Temperature monitoring is widely used in civil construction, stored grain warehouse, intelligent building, air conditioning system and other industrial and agricultural production. The traditional method of temperature measurement is in each monitoring point layout of the temperature probe, temperature data acquisition timing of each point by hand every day, and then enter the computer storage, and generates the change of temperature, stress curve and the test report, some is through the data acquisition box collection temperature and stress data, and then make further data processing by upload computer cable.

传统的测量方法需要监测人员频繁来往于施工现场，劳动强度大，数据采集和传输不方便，信息管理的自动化程度低，难于满足现代信息化监测的要求。为了提高测温数据采集的准确性、可靠性、及时性，同时实现温度和应力数据的智能化、信息化管理，本文针对大规模建筑施工监测等工程应用的要求，设计了一种基于无线数据传输和USB接口的多节点远程温度监测系统。

The traditional measurement method needs monitoring personnel to frequent the construction site. The labor intensity is large, data collection and transmission is inconvenient, and the automation degree of information management is low, so it is difficult to meet the requirements of modern information monitoring. In order to improve the accuracy, reliability and timeliness of temperature data acquisition, at the same time and temperature should be intelligent and information management data, in accordance with the requirements of large-scale construction monitoring project application, design a remote multi node wireless data transmission and temperature monitoring system based on USB interface.

通过无线数据传输，一方面拓展了节点分机布置的空间范围，另一方面大大缩短了测温电缆的长度以方便布线。USB接口实现了将各节点分机的测温数据向主机的快速传输，取代了传统的RS 232等接口形式，大大方便了与主机的连接。主机软件完成数据的转换、存储、曲线和报表生成，实现混施工监测的信息化管理，也可以构建一个Web服务器，实现信息的异地监测。

Through the wireless data transmission, on the one hand, it expands the space range of the node layout, on the other hand, it greatly shortens the length of the temperature measuring cable to facilitate the wiring. The USB interface realizes the fast transmission of the temperature data from each node to the host, instead of the traditional RS 232 interface. It greatly facilitates the connection with the host. The host software completes data conversion, storage, curve and report generation, realizes information management of mixed construction monitoring, and also constructs a Web server to achieve remote monitoring of information.
