But it is hard for us to monitor the temperature and humidity of the warehouses. As an important indicator of warehouse management, warehouse temperature and humidity needs informational management, also can achieve the automation of warehouse management. Now, the main technology of temperature and humidity monitoring system is CAN bus communication design, computer integrated control technology and shared bus transmission media mode of local area network using CSMA/CD technology. The detection system which has been widely used in the Modbus protocol is adopted in this paper. This system has good real-time, high accuracity, in the simulation of the mutual transfer between two control devices, I / O and register data, MODBUS compatibility making it integrated management system interface. In this paper, basing on the advantages of each monitoring system and the scope of adaptation of the comparative analysis, we select the appropriate monitoring system design. We choose the monitoring system based on MODBUS protocol, in the automation, the integrated management system, the transmission accuracy and so on under the different conditions of satisfaction. In this paper, the hardware design and software design of each chip are introduced, and the design and research ideas are described. Keywords: Computer integrated control technology; Modbus protocol; automation; integrated management system; temperature and humidity monitoring目 录 第1章 绪论 1 1.1 课题背景及其意义 1 1.2 国内外研究现状 1 1.2.1 基于RS485总线的监控系统 1 1.2.2 基于以太网的监控系统 2 1.2.3 基于CAN总线的监控系统 3 1.3 本设计的实用价值 4 1.4 设计的理论意义 4 1.5
