摘要
针对目前温度控制在工业生产中被广泛应用,而传统的温度控制系统是由功能繁杂的大量分离器件构成,为了节约成本,提高系统的可靠性,设计了一种基于C8051F040的温度控制系统。在该系统中,为了减小干扰的影响,用低通数字滤波算法对采样数据进行处理,然后用PID算法进行决策输出。同时,利用CAN总线和其他节点进行数据交换。经过测试,该系统的技术指标满足要求,运行稳定可靠。
Specially the temperature control systems are extensively used at present,while the traditional temperature control sys- tems consist of abundant discrete devices.in order to lower the cost and improve the system reliability,the temperature control system based on C8051F040 is introduced in this paper.In the system,the sample data are deal with low-pass digi- tal filtering algorithm to decrease the disturbance,and then the output is deduced with the PID algorithm. At the same time,the controller can exchange data with the other nodal points by CAN bus.It is proved that the technical index of the system is satisfied and it works steady.
