Abstract

The utility model discloses a control instrument of a microcomputer control road lamp, which relates to a road lamp automatic switch. The control instrument solves the problems that light-control road lamp switch has poor interference resistance capability and the turning-on and turning-off time is much arbitrary. The utility model uses astronomical data and works out local sunrise and sunset time through the microcomputer. Finally, the turning-on and turning-off time of the road lamp is determined. The utility model also has the function of multiway control and can stagger the turning-on and turning-off time of multiway road lamps so as to reduce the impact of an electric network.

Description

Microcomputer street lamp controller

Technical field

The utility model is the control device that a kind of special control street lamp opens or closes by certain hour.This device can be according to local longitude and latitude, calculate the correct time of sunrise sunset every day in local 1 year by microcomputer, determine the time of road lamp switch every day, described microcomputer street lamp controller is a multichannel controller, can control one group or two groups of above street lamps, so that the time difference of road lamp switch is opened, removes the impact that electrical network is caused from.

Background technology

Known road lamp switch control method generally has following several: at first be the hand control switch method, the shortcoming of this method is significantly, and is superseded substantially.Next is light-operated method, utilizes the illumination of light exactly, and switch cuts out in the time of light intensity; Switch opens when light is weak all adopts this method as Chinese patent 87206272 and Chinese patent 90222525.1.The shortcoming of this method is that antijamming capability is relatively poor, inconvenience control switching time, and switching time, error was bigger.In addition, the method that also has a kind of remote control switch.The remote control thereof cost is higher, and is not too suitable for the street lamp control of small and medium-sized cities.

Summary of the invention

The purpose of this utility model provides a kind of economical and practical, controls reliable street lamp controller.The utility model has been abandoned light-operated and the method remote control switch street lamp, utilizes chronometer data, promptly uses the weights and measures of the precise time of sunrise sunset as road lamp switch, reaches the purpose of accurate control road lamp switch.

Concrete technical scheme is: microcomputer street lamp controller has nixie display, input keyboard, patchboard also comprises the central processor CPU that has calculating and Control Software, clock controller, be used to store the storage and the self-checking system of longitude and latitude and result of calculation, a plurality of relays.Described central processor CPU is connected with described nixie display, described input keyboard, described storage and self-checking system, described clock controller, described a plurality of relay circuits respectively, and described a plurality of relays are connected with described patchboard circuit.

The utility model uses a microcomputer, and promptly single-chip microcomputer calculates the precise time of the sunrise sunset of every day in a year by the longitude and latitude of locality, and as demarcation, determines that the regular hour is poor, the final switching time of determining respectively to organize street lamp.Continuous control system when the utility model also is provided with promptly can be by manually being provided with the road lamp switch time.When needing interim switch street lamp under special circumstances, the program in manually can the direct intervention microcomputer opens or closes street lamp in the time of needs.The utility model also is provided with multichannel control, and being about to that several street lamps compile is one group, or becomes one the tunnel, and the utility model can be controlled two-way, or the street lamp of multichannel more, so as the time difference that the street lamp of some is opened or closed open, to reduce impact to electrical network.Simultaneously can in the time of needs, close some street lamps, so that economize on electricity.

The special-purpose software program of one cover is arranged in CPU, be used for calculating and control.Set year, month, day and standard time by input keyboard and nixie display, with the longitude and latitude input of locality, close one group or several groups of street lamps at midnight or other times if desired simultaneously, then set the shut-in time in advance.CPU obtains the time that the street lamp of every day in 1 year opens and closes after as calculated, and with these storage in storage and self-checking system.CPU passes through from the time signal of the date that clock obtains the sun set/raise time of corresponding which date in this time signal and the memory to be compared during use, determines the road lamp switch time of that day.CPU determines the road lamp switch on the same day after the time, is added the time difference distribution afterwards of a few minutes sends in each relay this time, and each relay opens or closes respectively by patchboard and respectively organizes street lamp.

The beneficial effects of the utility model: the utility model has overcome Light control road lamp too random shortcoming switching time, and antijamming capability is very strong, is subjected to the influence of the bright degree of surrounding environment and temperature very little.Because the cost of single-chip microcomputer and accessory thereof is very low, so the manufacturing cost of a whole set of controller and use cost are also very low.

Specific embodiment

External form of the present utility model as shown in Figure 1; Fig. 2 is a theory diagram of the present utility model, among the figure: 1. nixie display; 2. input keyboard; 3. patchboard; 4. central processing unit; 5. time controller; 6. store and self-checking system; 71.72.......7n. many relays.The utility model is made up of nixie display 1, input keyboard 2, patchboard 3, central processing unit (CPU) 4, clock controller 5, storage and self-checking system 6 and Duo Ge relay 7, and the special-purpose software program of a cover is arranged in CPU 4, is used for calculating and control.The concrete course of work is: at first set year, month, day and standard time by input keyboard 2 and nixie display 1, simultaneously the longitude and latitude of locality is imported, close one group or several groups of street lamps in advance at midnight or other times if desired, then set the shut-in time in advance.CPU 4 obtains the time that the street lamp of every day in 1 year opens and closes after as calculated, and with these storage in storage and self-checking system 5.CPU 4 passes through from the time signal of the date that clock controller 5 obtains the sun set/raise time of corresponding that date in this time signal and the memory to be compared during use, determines the road lamp switch time of that day.The road lamp switch that CPU 4 determines the same day adds this time the time difference distribution afterwards of a few minutes sends in each relay 7 after the time, and each relay 7 opens or closes respectively by patchboard 3 and respectively organizes street lamp.
