主令開關(guān)是機(jī)械設(shè)備中重要的控制元件之一，也被稱為主操作開關(guān)或總開關(guān)。它主要用于控制機(jī)器的啟動(dòng)、停止和故障診斷等功能，以確保設(shè)備的安全性和可靠性。
從機(jī)械結(jié)構(gòu)上來看，主令開關(guān)通常是一種大型的手柄，在緊急情況下可以快速切斷電源或油路，以保證機(jī)械操作的安全性。因此，主令開關(guān)的名稱中“主”和“令”的含義是非常重要的，它代表著這個(gè)開關(guān)對(duì)整個(gè)機(jī)械系統(tǒng)的掌控能力和指揮作用，說明了它在機(jī)械設(shè)備中的重要性和不可替代的地位。
主令開關(guān)的命名來源于計(jì)算機(jī)體系中的總線結(jié)構(gòu)。
1. "主令"指的是CPU發(fā)送的指令，意義重要，因此必須得以高速穩(wěn)定的傳輸。
主令開關(guān)可以連接到計(jì)算機(jī)的總線中，在保證消息高速傳輸和準(zhǔn)確性的基礎(chǔ)上，將主令分發(fā)到不同的設(shè)備中，實(shí)現(xiàn)計(jì)算機(jī)的整體操作。
2. 每一臺(tái)計(jì)算機(jī)硬件架構(gòu)的總線結(jié)構(gòu)是不同的，故不同計(jì)算機(jī)廠商的主令開關(guān)也存在差異。
一般來說，主令開關(guān)是實(shí)現(xiàn)計(jì)算機(jī)指令傳輸?shù)年P(guān)鍵設(shè)備，而其名稱來源于總線結(jié)構(gòu)中信號(hào)分配的特殊性質(zhì)。
