Abstract
The utility model discloses a control device with a mark position generally for scavenger fans. The utility model belongs to the field of SCM technology application and is characterized in that the states of ground connection and the hanging of a mark position are used for identifying various control modes of remote control and wire control. Thus, different control of eight scavenger fans with different functions is realized. Moreover, the utility model is connected with an I/O input terminal of a host machine of a control board. Coded signals decoded by the host machine control a switch circuit connected with an I/O output terminal of the host machine, and thus the operation of the scavenger fans connected with the switch circuit is controlled. The wire control mode adopts a touch button to connect with the I/O input terminal of the host machine, and thus the function same as that of a remote control device is accomplished. The utility model is created for controlling scavenger fans in a sucking type, a corner type and a wall hanging type and scavenger fans with negative ions. The utility model realizes the function of interaction, interlocking, timing, time delay, etc. among ventilation, air exchange and negative ion air purification.
Description
Technical field the invention relates to the ventilation fan control gear, particularly has the ventilation fan general purpose control device of flag bit.Belong to microchip technology field.
The background technique ventilation fan claims ventilation fan again, by ventilating, taking a breath or be equipped with the anion air purifying device and form, has ventilation, ventilation or anion fine-purification function, is installed in parlor, bedroom, kitchen and toilet, is used for the indoor air circulation.Ventilation fan a large amount of insalubrious bacteriums that suspend of comprehensive neutralization when removing pyrotechnics of anion fine-purification function are housed.Have various ways such as top, angie type and the wall hanging of suction according to the mounting point.Before the invention application, ventilation fan adopts switch on wall to control its break-make more, and control brings operation inconvenience one to one, does not more have timing, delay function.
The purpose of summary of the invention the invention provides a kind of ventilation fan general purpose control device with flag bit.
The invention solves the technological scheme that its technical problem adopts: comprise two kinds of control modes of flag bit and remote control line traffic control; The single-chip processor i/o port is provided with flag bit, and flag bit is ground connection and unsettled combination.The flag bit of single-chip processor i/o port setting is ground connection and unsettled combination, the whole no marks position single-chip microcomputers that are equivalent to when unsettled of flag bit.Remote control unit is made up of control panel, infra-red remote control transmitter, receiver of remote-control sytem three parts, its Placement is: button is connected with encoder in the remote control transmitter, receiving tube is connected with the single-chip processor i/o input end in the receiver of remote-control sytem, the single-chip processor i/o output terminal is connected with switching circuit, and described switching circuit comprises switching tube, integrated negative circuit, relay, silicon controlled set, subclass.Touch-switch is connected with the single-chip processor i/o input end in the line control unit, and switching circuit is described consistent with claim 3.
The beneficial effect of the invention is: with all kinds of different control functions of remote control transmitter may command, the ventilation fan work of controlling object, the identification of service marking position simultaneously will be controlled one to one and become pair of control.Use line control unit can avoid the switch on wall control circuit not have functions such as interaction, interlocking and time-delay, also have more Security,
Description of drawings is further described the invention below in conjunction with drawings and Examples.
