Description
Technical field the invention belongs to microchip technology field, particularly can distinguish a plurality of input signals in order to open and close the general single chip standard chips of impulse electromagnetic valve according to flag bit.
The general single-chip microcomputer standard chips of impulse electromagnetic valve of background technology the invention band flag bit is applied to that all kinds of water-saving band water tank toilet seats, squatting pan, no water tank toilet seat, urinal, buttock-cleaning type toilet seat etc. are subjected to infrared induction, pyroelectric sensing, manually one or more control modes such as click type provide unified singlechip control chip by 6 liters of stool baths, urine bath 3 raising of indices standards to the control circuit of cistern water supply or automatic or manual flushing after an action of the bowels in order to distinguish stool and urine.And before the invention applying date, the impulse electromagnetic valve control chip is the control one to one of single control mode both at home and abroad.Cause the waste of mcu resource, the production cost height also is unfavorable for the intensification production of single-chip microcomputer, and Software Secondary Development causes waste of manpower resource simultaneously.Do not distinguish the stool and urine bath and cause water resource waste.
The purpose of summary of the invention the invention will provide a kind of different controlling object unlike signal input mode exactly, in order to open and close impulse electromagnetic valve, finish the standard chips of the control circuit of distinguishing all kinds of water-saving toilet bowls that stool and urine need wash by water, in control chip, be solidified with 2
NKind of control program, single-chip microcomputer is according to the ground connection of N+1 flag bit and unsettled, differentiation distinct program and different controlling object.The standard chips that the invention provides helps the intensification production of single-chip microcomputer, and saving manufacturing cost and release has the overlapping development of family to the Single-chip Controlling program.Also be applicable to simultaneously the closet control of not distinguishing the stool and urine bath.
The invention comprises control program and the ground connection of N+1 flag bit and the selection of vacant state of curing., do not comprise peripheral circuits such as infrared induction, pyroelectric sensing, click keys and cistern water level sign.
The advantage of the invention is the selection of described standard chips by the unsettled two states of ground connection of flag bit, can be all kinds of water-saving toilet bowls provides the standard chips of control circuit, help extensive intensification and produce, reduce cost, its extensive use helps the conserve water resource.
The invention solves the technical scheme that its technical problem adopts: the invention is solidified with 2 at single-chip microcomputer memory fixed address
NIndividual control program is provided with N+1 flag bit at the fixed address of I/O port, single-chip microcomputer according to flag bit whether the state of ground connection determine the quantity of controlling object, call 2
