sound equipment driving circuit.When this end is low level, buzzer call.11,12 pin of U1 cause ventil YA.9,8 pin of U1 are connected on respectively on the base stage of triode T2 and T4, and the base potential of T2 pulling triode T3 is finished the diaphragm valve energising and sucted action.Little electric current after triode T4 sucts as diaphragm valve is kept control.The U7 unit is the 24C45 chip, as the current failure memory unit of water yield information.15 ends by U1 are controlled through reverser U8, and U8 adopts the 74HC00 chip.Data message is sent into the SK of U7 and DI, DO three ends by 14,13 pin of U1 unit.The AS end of reset key FA and U7 does to reset control through Sheffer stroke gate U8.When pressing reset key FA or AS end for low level, single-chip microcomputer resets.Single-chip microcomputer adopts the 11.0592M crystal oscillator.After IC-card inserts deck U2, single-chip microcomputer reads the water yield and the temporal information that card is gone up storage, traffic sampling information is sent into single-chip microcomputer by sampling unit U3 and is carried out integrating, and compare with the water yield information of Card Reader, when the two was equal, the control end 8 of U1 became high level, and triode T4 is ended, diaphragm valve dead electricity and closing is cut off and is supplied water.The clock that single-chip microcomputer is drawn, the displayed value that data and control end make display driver unit U4, U5 provide the water amount to successively decrease in real time for nixie display U6, but for reducing power consumption, only in plug-in card input water yield information or when pressing display key XA, charactron is just obtained positive supply and luminous.Behind each single-chip microcomputer Card Reader, promptly export high level and make triode T2 and T3 conducting, the 24V direct supply is introduced the diaphragm valve coil make it suct moving iron core, after 2-3 delay time second, promptly, enter long-term low power operation by the power supply of keeping of triode T4 connection 3-5V.When the water amount dropped to certain threshold values, single-chip microcomputer output terminal 16 presented low level under the management of software, made the hummer sound that shakes, and kept a short time delay to purchase water with the prompting user.After the user heard, available ventil YA eliminated sound equipment.Intelligence controlling device can be provided with special-purpose power pack, 220V/24V/8V step-down transformer and rectification, filtering is housed, voltage stabilizing element in the box.Interrupt for preventing that interruption once in a while because of civil power from causing to supply water, be provided with accumulator in box, powered by civil power at ordinary times, accumulator can be kept diaphragm valve and continues to open water supply when civil power interrupted.
