1.Output in NO mode means
- the output controls a heat element
輸出控制一個加熱元件
- if the temperature is reached, the heat element will be switched off
當(dāng)溫度達(dá)到了25度,那么加熱元件關(guān)閉 - the regulation is controlled by a PLL
這里的這個PLL是什么意思,我只知道PID算法 - temperature stability shall be better than ±0.2K
溫度的穩(wěn)定性要優(yōu)于0.2K,這里的精度要求可以用軟件算法實現(xiàn)嗎? 如果我前面用的是NTC 10K 1%,有影響嗎
2.Output in NC mode means
- the output controls a fan to prevent over temperature
啟動風(fēng)扇防止過熱
- if the temperature is reached, the fan will be switched on- the regulation is only on off. No PLL - temperature stability (Hysteresis) shall be better than ±1K
啟停延時滯后小于一度
3.這些加熱組件是外部供電,加熱片是5V3A或者是24V2A的,由單片機(jī)控制的工作開關(guān),那要怎么實現(xiàn)呢,是用光耦和可控硅嗎?繼電器呢? 完全沒有硬件設(shè)計經(jīng)驗,畢設(shè)做的有點吃力,謝謝大家的幫助了
