摘要
针对水产养殖传统加温采用锅炉(燃煤、燃油或用电)加热装置能耗高、功率低、污染严重、运行费用高等缺点,设计一款以电磁感应原理为基础的超音频感应加热装置。该装置以高速数字信号处理器TMS320F2812DSP为控制核心,完成了频率跟踪的数字锁相环(DPLL)设计,采用模糊PID控制方法对温度进行实时动态调整,实现了高精度数字化控制的恒温供水系统。样机试验表明,该装置加热速度快,精度高,效率高,节能环保。
According to the traditional aquiculture heat boiler （coal, fuel or electricity） heating devicehas high in energy consumption,low power, pollution serious, and operation cost higher etc shortcomings, a kind of electromagnetic induction based on the principle of super audio induction heating device was put forward. With high speed digital sig- nal processor TMS320F2812DSP as control core, finished design of frequency tracking digital phase lock loop （DPLL）, the fuzzy PID control method to real-time dynamic adjustment of temperature, and realized the precise control of the water supply system digital constant temperature. The prototype test show that the device has fast heating speed, high precision, high efficiency, energy saving and environmental protection.
