Embodiment Construction
[0011] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, this embodiment includes a single-chip central processing unit, a thyristor and its control circuit, and the thyristor and its control circuit are packaged in a module, which is completed by the main control board. The central processing unit of the single-chip microcomputer is the control center, and the instructions are set by the control box. The thyristor in the thyristor intelligent control module is connected in parallel with a high-power magnetic latching relay. The dynamic and static contacts K of the relay are connected in parallel with the anode and cathode of the thyristor D. The output signal control, including the pull-in and disconnection of the magnetic latching relay, the signal output terminals of the start key and stop key ( Figure 4 Commonly referred to as key input) are respectively connected to the signal input end of the central processing unit, and the signal output end of the cent...
