(3) limit the safe and reliable region that is not subjected to, and the simple and convenient distribution of being convenient to is installed, and does not need to set up remote transmission line, and the construction period is short;

(4) noiselessness, pollution-free, not water consume fuel not.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the utility model circuit block diagram.

Fig. 2 is the utility model fundamental diagram.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

With reference to figure 1, shown in Figure 2:

A kind of intelligent solar sense light circuit of automatic perception seasonal variations, this circuit comprises single-chip microcomputer, power module of voltage regulation, induction module, analogue collection module, feedback module, charge control module, charging module and output module, provides the power module of voltage regulation of working power to link to each other with single-chip microcomputer; Being used to respond to the induction module that extraneous human body changes directly links to each other with single-chip microcomputer; Judge that battery capacity and light-operated analogue collection module and the single-chip microcomputer that starts to control a little join; The feedback module of the electric current of voltage on the collection feedback resistance and control load output links to each other with single-chip microcomputer; Charge control module control connection charging module, and link to each other with single-chip microcomputer; The output module whether control load is exported links to each other with single-chip microcomputer.

Power module of voltage regulation is a supply module, and it is made up of capacitor C 3, C4, C6 and C7, and is connected by corresponding circuit and has formed its power supply circuits on the chip, and provides normal working power as programming device CPU; Feedback module is provided with C8 and the R9 that strobes, and R10 is a feedback resistance, and feedback module comes the electric current of control load output by the voltage of gathering on the feedback resistance; Its automatic inducing function is that inductor 1 and an inductive reactance R8 form its sensor circuit outside releasing by a heat on induction module, induction module can be responded to the variation of external environment light and human body, the utility model induction module is transferred to single-chip microcomputer with induction information, make the Single-chip Controlling output module, it is very bright that LED0 on the man-hour output module will become, be convenient for people to outdoor activities, the energy has been saved in LED0 meeting deepening when nobody.

In analogue collection module, wherein the R1 of She Zhiing, R2 have formed the sampling bleeder circuit of storage battery, this potential circuit is connected in the outlet of CPU, bleeder circuit is given single-chip microcomputer GP0/AN0 and is done A/D conversion back and measure its battery tension, can prevent since like this over-charging of battery and put the generation of phenomenon.If find during charging that cell voltage is higher, then single-chip microcomputer GP5 output high level makes the Q6 conducting, and Q5 ends, the Q2 conducting, and Q1 ends, and disconnects charge circuit, prevents to overcharge with this and causes influence to entire circuit; When discharge, single-chip microcomputer GP2 exports high level, allows the LED loop works, puts a little when cell voltage is lower than, and then the GP2 output low level is forbidden discharge.

After R3, R4 dividing potential drop, give single-chip microcomputer GP1/AN1 and make A/D conversion back judgement ambient light illumination usefulness.Solar array voltage descends after the darkness, when sampling voltage single-chip microcomputer GP2 output high level during less than set point, allow the LED loop works, the number of times of record each period induction night simultaneously, the same period of second day night determines the pattern of bright lamp according to the induction number of times of record, according to the brightness of season and induction number of times decision LED, at day the GP2 output low level is forbidden discharge.Note the time from the darkness to the daybreak simultaneously, second day is benchmark calculates night according to prior agreement bright lamp period and bright lamp pattern with this time.Because the length at night is different throughout the year, single-chip microcomputer has the function of intelligence learning, very approaching because of adjacent two days length at night, the length of measuring in available first day at night is calculated the lighting time at second day night, and this has just solved the unfixed difficult problem of length at night.

The utility model reaches following beneficial effect:

(1) the utility model has strong and weak judgement of sensitization preferably and light and then Based Intelligent Control loaded work piece pattern to external world according to the changes of seasons situation;

(2) according to user's actual conditions Based Intelligent Control loaded work piece pattern, effectively prolong the loaded work piece time, the management of charging and discharging function by adding is reasonably used to the energy content of battery;

(3) limit the safe and reliable region that is not subjected to, and the simple and convenient distribution of being convenient to is installed, and does not need to set up remote transmission line, and the construction period is short;

(4) noiselessness, pollution-free, not water consume fuel not.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
