The greenhouse ground hotline controller circuit is composed of the power supply circuit and heating control circuit, and the circuit is shown as the chart. Power supply circuit is composed of the fuse FU, power transformer T, rectifier diodes VD1 ~ VD3, resistor R1, three-terminal voltage regulator integrated circuit IC and the filter capacitor C1. Heating control circuit is composed of the resistors R2 ~ R5, capacitor C2, voltage regulator diode VS, Schmitt trigger NAND gate integrated circuit IC2 (D1 ~ D3), JK flip-flop integrated circuit IC3 (A1, A2), count / pulse divider IC IC4, selector switch S, transistor V, thyristor VT and ground hotline EH. R1 ~ R3 and R5 select 1/2W metal film resistors.
