摘要：Temperature is one of the important factors that ensure the quality and safety of construction. According to the characteristics of construction site environment, an automatic multi-channel real-time monitoring system of construction site environment temperature is developed based on virtual instrument technology. Combined with ZigBee wireless transmission technology, this system can realize remote real-time temperature monitoring for construction site. The system hardware consists of main controller, gateway, wireless sensor nodes and thermocouple temperature sensors. The temperature information is collected by thermocouples. Through wireless sensor network nodes, the data is sent to main controller terminal via gateway. LabVIEW graphical programming language is used for program design. The function of real-time remote temperature information data display, data analysis, limiting value alarm, trend monitoring and data storage for multiple objects simultaneously is realized in this system. And the developed automatic temperature monitoring system can provide support for the temperature-related management of construction site.
