The pressure tank air pressure abnormality detection alarm circuit is composed of the pressure control circuit, LED indication circuit and voice alarm circuit, and it is shown as the chart. The air pressure measurement and control circuit is composed of the power switch S, battery CB, electric contact pressure gauge Q. LED indicator circuit is composed of the green LED VL1, red light-emitting diode VL2 and resistors R1, R2. R1 ~ R3 select the t/4W metal film resistors or a carbon film resistors. C1 select the electrolytic capacitor with voltage in 16V: C2 uses the high-frequency ceramic capacitor. VD1 and VD2 use 1N4001 or 1N4007 type silicon rectifier diodes.
