Abstract
The utility model relates to a peripheral structure of the sharing chip of a flush type intelligent water saving product, and relates to a single-chip microcomputer peripheral structure of the sharing chip, in particular to relate to a peripheral structure of the sharing chip of a flush type intelligent water saving product. The utility model comprises a single-chip microcomputer interface which is used for connecting peripheral circuits of a pressure switch, an infrared emitting and receiving apparatus circuit, a magnetic valve circuit and so on. The utility model is characterized in that a group of zone bit is provided to distinguish the pressure switch, and the infrared emitting and receiver circuit and a sharing circuit of the pressure switch and the pressure switch and the infrared emitting and receiver and other input modes through the different combination of the grounding of the zone bit and hanging. The sharing chip of the flush type intelligent water saving product created by the utility model is used to choose the different peripheral structures, the different water saving product is controlled through the same chip, and comprises a toilet bowl, a squat pan and a urinal stall and so on, to be used to distinguish stool or urine flushing automatically or by hand, also can be used on a contact free flushing tap, and the purpose of water saving can be achieved.
Description
Technical field the invention relates to a kind of one-chip machine common chip peripheral structure, and particularly a kind of peripheral structure of sharing chip of built-in intelligent water-saving product belongs to singlechip technology in the control Application for Field.
The control chip of the prior art intelligent water-saving product before background technology the invention adopts man-to-man control mode, causes the wasting of resources of singlechip chip.
The purpose of summary of the invention the invention provides a kind of peripheral structure of sharing chip of built-in intelligent water-saving product.
The invention solves the technical scheme that its technical matters adopts: the peripheral structure of sharing chip of built-in intelligent water-saving product comprises in order to connect the interface microcontroller of pressure switch, infrared and peripheral circuits such as acceptor circuit and solenoid valve control circuit; Have a group mark position, the interface microcontroller of zone bit and pressure switch, infrared receiver circuit and solenoid valve control circuit constitutes the peripheral structure of sharing chip of intelligent water-saving product.Zone bit is to have to connect and the microswitch that disconnects two states, and the one end is connected with shared chip I/O respectively, its common end grounding.One end of pressure switch is connected with shared chip I/O, and the ring that is installed on toilet down or the inferior body-support point during with the lavatory of the pedal of squatting pan.Infrared is connected with shared chip I/O with the acceptor circuit output terminal.Solenoid valve control circuit is connected with shared chip I/O respectively by the input end of two groups of switching tubes, and two groups of output end of switching tube are connected with the two ends of electromagnetic valve coil respectively.
The beneficial effect of the invention is the co-used chip of built-in intelligent water-saving product, by selecting different peripheral structures, realize that same chip control different saving product of water, comprise toilet, squatting pan, urinal etc., the bath of automatic distinguishing stool and urine, also can be used for exempting from the contact water flushing tap, all can reach water-saving purpose.
Description of drawings Fig. 1 is the electrical schematic diagram of the invention.
Embodiment is referring to Fig. 1.The peripheral structure of sharing chip of built-in intelligent water-saving product comprises in order to connect pressure switch K1, K2, the interface microcontroller of peripheral circuits such as infrared and acceptor circuit A and solenoid valve control circuit; Have a group mark position B1, B2, zone bit B1, B2 have to connect and the microswitch that disconnects two states, and the one end is connected with shared chip I/O (1), I/O (2) respectively, its common end grounding.The ground connection of zone bit B1, B2 is represented selection pressure K switch 1 respectively with unsettled promptly the connection with four kinds of combinations that disconnect; Pressure switch K1, K2, input modes such as infrared and acceptor circuit and pressure switch and infrared and acceptor circuit common circuit.Zone bit B1, B2 and pressure switch K1, K2, the interface microcontroller of infrared receiver circuit A and solenoid valve control circuit constitutes the peripheral structure of sharing chip of intelligent water-saving product.Pressure switch K1, K2, an end are connected with shared chip I/O (3), I/O (4) respectively, and the ring that is installed on toilet down or the inferior body-support point during with the lavatory of the pedal of squatting pan.Infrared is connected with shared chip I/O (5) with acceptor circuit A output terminal.Solenoid valve control circuit is connected with shared chip I/O (6), I/O (7), I/O (8), I/O (9) respectively by the input end of two groups of switching tube G1, G2, G3, G4, and the output terminal of two groups of switching tube G1, G2, G3, G4 is connected with the two ends of electromagnetic valve coil D respectively.
Present embodiment infrared receiver circuit and infrared transmitter circuit are prior art, and the design main points of non-the invention are omitted in the accompanying drawings.Its design main points only are infrared receiver circuit output end A and mode that shared chip I/O port is connected.As shown in the figure.
8-bit microcontroller is adopted in the invention.The present embodiment co-used chip adopts the 8-bit microcontroller PIC16C54 of U.S. MICROCHIP company.
