Abstract

An electronic program controlled switch which can be timing connected or disconnected according to compiled program, intraday connection and disconnection time constant respectively calculated according to everyday time of one year and equation of time are fixedly lodged in 892051 SCM (2), P<33>, P<34>, P<35> of 892051 SCM (2) and 1302 clock system time generator (1) of clock signals year, month, day, hour, minute and second generated by external connection of RST port; control apparatus are connected between RXD of SCM (2), interface P<32>TXD and port P<37>, P<10>, P<11>, P<12>, P<13>, P<14>, P<15>, between which a control electrical apparatus (7) and a connection and disconnection time displays decoding drive circuit (4) are connected; an output port of the drive circuit (4) is connected with an AC switch (6). The utility model mainly applies to street lamp control in cities and towns, and can be unmanned automatically turned off for a long time.

Description

The electronic program switch

Technical field

The utility model relates to the switch in a kind of electronic circuit, particularly a kind of can be according to the electronic program switch of the program break-make of having worked out.

Background technology

At some unattended special occasions, electrical appliance need be switched on or switched off according to the time that people design in advance, then have the people designed time switch and some according to change of external conditions be switched on or switched off switch, as audio-switch, light-operated switch or the like.These switches are used for some field and have produced fabulous effect, but in some special field effect just is not desirable especially, as when being used for the automatic control of public street lamp, the large-scale outdoor lights light advertising board in city etc., it is too mechanical that time switch often seems, can not realize control according to change of external conditions, be easy to generate the phenomenon of early opening (passs) or pass in evening (opening), cause unnecessary electric energy loss or darkness and can not open the drawback of electrical appliance on time; And audio-switch, light-operated switch etc. are subjected to external interference to produce misoperation easily.

Summary of the invention

The utility model purpose is to overcome weak point of the prior art, designs a kind ofly can reach accurate gauge tap according to the electronic program switch of the program break-make of having worked out.Project organization of the present utility model specifically is: a kind of electronic program switch that can be switched on or switched off according to the program timing of having worked out, the turn-on time on the same day that calculated respectively according to the time length of 1 year 365 day every day and the different region time difference same day that the time length that it is characterized in that fixedly depositing with good grounds one year 365 day every day in 892051 single-chip microcomputers (2) and the different region time difference calculate respectively and the time constant of trip time, the P of 892051 single-chip microcomputers (2) ₃₃, P ₃₄, P ₃₅External with the RST port in order to produce 1302 clock system time generators (1) of year, month, day, hour, min, second clock signal, RXD, the P of single-chip microcomputer (2) ₃₂, TXD interface and P ₃₇, P ₁₀, P ₁₁, P ₁₂, P ₁₃, P ₁₄, P ₁₅Be connected to the time showing decoder driver circuit (4) of control electrical appliance (7) through and off between the port, the delivery outlet of driving circuit (4) connects electronic AC switch (6).

At single-chip microcomputer P ₁₆, P ₁₇Also inserted programmed switch (3) manually on the port.

At electronic AC switch (6) and electrical appliance (7) but between insert the restrictor (5) of realizing regulating electrical appliance power by monolithic processor controlled timing automatic.

Program in the utility model electronic program switch is 1 year to be 365 days according to the Gregorian calendar, there were 12 months in 1 year, the annual Summer Solstice was June 21 or 22 days, Winter Solstice was Dec 21 or 22 days, just in time be separated by six months, this natural periodic regularity, again according to the time length of every day, by the different region time differences of China, calculate the ETAD expected time of arrival and departure (electrical appliance is connected constantly) and the pass time (electrical appliance disconnects constantly) on the same day respectively, be set at out night, is set at the pass morning, and this time constant imported in 892051 microcomputers fixedly deposit.Then, carry out the time contrast, and produce out signal and close signal, to realize control electrical appliance with this computer assembly language programming.When programming, also the power that can set electrical appliance in the late-late time period limits, to reach the purpose of economize on electricity.

The utility model is mainly used in the street street lamp control in city, county and town, is not having under the situation of artificial open and close, can realize closing down automatically for a long time, and is not only laborsaving but also economize merit, very practical.Simultaneously, this switch also is applicable to the control of the public street lamp that office building corridor, compound and the gate etc. of office, army, hospital, school, factories and miness unit are located.Also can implement timing controlled to the public street lamp of the large lamp box billboard in city, neon bulb, residential building stair, family members institute, generally, range of application is very extensive.

The utility model advantage is:

1, this small product size is little, and is in light weight, reasonable in design, aesthetic in appearance, installs very conveniently, and security performance is reliable.

2, it is very beneficial to saves energy this switch to be installed.As regulating the dark bright degree of lamp at dead of night automatically, promptly energy savings can prolong the street lamp life-span again, reduces expenses, and people or vehicle are had no effect.

3, this switch is a microelectronic product, and it is little to consume energy, and designed life, under the situation of not having maintenance, but long-time running and use were desirable electronic switches in the 8-11 year.

Embodiment

A kind of electronic program switch that can be switched on or switched off according to the program timing of having worked out, the turn-on time on the same day that the time length of fixedly depositing with good grounds one year 365 day every day in 892051 single-chip microcomputers 2 and the different region time difference calculate respectively and the time constant of trip time, the P of 892051 single-chip microcomputers 2 ₃₃, P ₃₄, P ₃₅External with the RST port in order to produce 1302 clock system time generators 1 of year, month, day, hour, min, second clock signal, the RXD of single-chip microcomputer 2, P ₃₂, TXD interface and P ₃₇, P ₁₀, P ₁₁, P ₁₂, P ₁₃, P ₁₄, P ₁₅Be connected to the time showing decoder driver circuit 4 of control electrical appliance 7 through and off between the port, the delivery outlet of driving circuit 4 connects electronic AC switch 6.At single-chip microcomputer P ₁₆, P ₁₇Also having inserted programmed switch 3 manually on the port, made this electronic program switch have more dirigibility and make things convenient for the user, mainly is that artificial the pressure turned off the light, artificial force switch, artificial timing is turned off the light, and manually regularly turns on light etc., has accomplished automatically and the manual reasonable combination of controlling.But between electronic AC switch 6 and electrical appliance 7, insert the restrictor 5 of realizing regulating electrical appliance power by monolithic processor controlled timing automatic, can regulate the dark bright degree of lamp at dead of night automatically, promptly energy savings can prolong the street lamp life-span again, reduce expenses, people or vehicle are had no effect.
