摘要
合适的温湿度是生鲜食品保鲜的重要条件,车载系统温湿度的实时监控采用Zig Bee网络的无线通信方式。为提高其精度,采用参数模糊自整定方法完善了模糊PID控制系统的自适应性能。结果表明,该系统精度高、成本低、可靠性高、超调量小、动态响应好,更有利于实时监控。
The appropriate temperature and humidity are important conditions for fresh food preservation. Real-time monitoring system of temperature and humidity was designed based on the ZigBee network communication. In order to improve the accuracy, fuzzy parameter adaptive control method was used to further perfect the adaptive performance of fuzzy PID control. The results showed that the system had high precision, low cost, high reliability, small surplus, good dynamic response. It improved the control of progress. It is better for real-time monitoring.
