基于CAN总线的花卉大棚温度测量系统

In recent years, the number of flower greenhouses is increasing day by day. In order to improve the production efficiency and reduce the production cost, at the same time satisfy the flowers' best growth environment conditions, it needs to carry on the intellectualized management to the flowers greenhouse. The intelligent management can be realized through the automatic adjusting temperature, humidity, light, carbon dioxide and other environmental factors. And the temperature control is the most important. This article has designed one kind of flower greenhouses temperature survey system basing on the CAN main line, introduces the system's network construction, the CAN node's hardware architecture, and the software design of data acquisition, demonstrating and saving. The system has high stability and good extendibility, which may make the flowers grow in the best temperature range, and may increase the flowers production.
