Abstract
The utility model discloses a general monolithic computer chip of an air exchanging fan with multiple control modes, which belongs to the single chip computer technology application field. The utility model is mainly characterized in that an I/O part of an eight-bit single chip computer is provided with one bit control mode zone bit, a two-bit control object zone bit and a two-bit decoding mode zone bit which are used for distinguishing two control modes of the wire control and the remote control, one of four kinds of combination for all or part control objects such as air exchange, blowing operation, negative iron, lighting, etc., and one of four different decoding modes. The arrangement of the zone bits is realized by the software, when the zone bit is zero, namely, the zone bit is not arranged. The utility model has multiple control modes, multiple control objects, and multiple decoding modes and can be applied in control circuits of various air exchanging fans, the utility model can be used as a standard chip to be directly selected by various air exchanging fan manufacturers, the secondary development for software is eliminated and the utility model is favorable for the effective use for the space resource and the intensive production of the single chip computer chip.
Description
Technical field the invention relates to the general singlechip chip of a kind of ventilation fan, and particularly a kind of general singlechip chip of ventilation fan with multiple control modes belongs to the single-chip microcomputer application.
Before background technique the invention applying date, do not have the general singlechip chip of ventilation fan of multiple control modes.Man-to-man control mode causes the waste of single-chip microcomputer space resources also to be unfavorable for the intensification production of single-chip microcomputer special chip.
The purpose of summary of the invention the invention just provides a kind of general singlechip chip of ventilation fan with multiple control modes.Be intended to overcome the control mode one to one of existing line traffic control, remote control ventilation fan control chip, four kinds of decoding processes such as all or part of controlling object of line traffic control, two kinds of control modes of remote control, ventilation, blowing, negative ion, illumination and PT2111 are concentrated in the same chip, by being distinguished and corresponding three group mark positions.
The invention solves the technological scheme that its technical problem adopts: comprise singlechip chip and flag bit, the I/O port of singlechip chip is provided with three group mark positions, i.e. 1 control mode flag bit, 2 controlling object flag bits and 2 decoding process flag bits.In order to distinguish line traffic control, two kinds of control modes of remote control, a kind of in a kind of in four kinds of permutation and combination of all or part of controlling object such as ventilation, blowing, negative ion, illumination and the four kinds of different decoding processes, setting by software of flag bit realizes, is equivalent to when flag bit is 0 and do not establish flag bit.1 control mode flag bit 1 is a flag bit ground connection, and 0 is that flag bit is unsettled, and definition 1 is the line traffic control mode, and 0 is remote control mode, also can oppositely define as required.Described 1 control mode flag bit has two kinds of combinations, and promptly 0,1, its Placement is: 1 is flag bit ground connection, and 0 is that flag bit is unsettled.0 is that flag bit is unsettled, and definition 1 is the line traffic control mode, and 0 is remote control mode, also can oppositely define as required.Described 2 controlling object composite marker positions have four kinds of combinations, and promptly 00,01,10,11, its Placement is: 1 is ground connection, and 0 is unsettled.Be respectively a kind of of the former compound modes of all or part of controlling object such as ventilation, blowing, negative ion, illumination.2 different decoding process flag bits have four kinds of modes, and promptly 00,01,10,11 its Placements are: 1 is ground connection, and 0 is unsettled.Corresponding with four kinds of decoding processes respectively.The I/O output of single-chip microcomputer is looked closely controlling object and is connected with the base stage or the intergrated circuit phase inverter input end of 1-4 switching tube respectively, and the output terminal of the collector electrode of triode or intergrated circuit phase inverter is connected with executive component relay coil or controllable silicon respectively.
The beneficial effect of the invention is: the invention collection multiple control modes, various control object and multiple decoding process are one, be applied in the control circuit of various ventilation fans, and directly select for use for all kinds of ventilation fan manufacturer as standard chips, remove Software Secondary Development from, help effectively utilizing the space resources of singlechip chip and intensification to be produced.
Description of drawings 1-Fig. 5 is the enforcement illustration of the invention.Single-chip microcomputer is a 8-bit microcontroller among Fig. 1.Embodiment's model is PIC16C57, also can selects PIC16C54 for use.I/O
