Description

Intelligent LED desk lamp control device

Technical field

The invention belongs to intelligent appliance field, relate to a kind of intelligent LED desk lamp control device, particularly one can according to the automatic regulating illumination intensity of desk lamp service condition, and point out user to carry out the intelligent desk lamp control device of having a rest.

Background technology

Desk lamp is the conventional household electrical appliance being used for during people live throwing light on, and is generally used for bending over one's desk working of night.The light source of LED desk lamp is made up of jointly multiple LED lamp bead usually, and when user leaves the illumination range of desk lamp, when namely user does not use LED desk lamp, all LED lamp bead are all lighted and will be caused energy waste.In addition, along with the quickening of modern life rhythm and the change of working method, increasing occupation needs staff to bend over one's desk working for a long time.And bend over one's desk working for a long time healthy meeting caused serious harm, such as, people who bends over one's desk working for a long time easily suffers from the diseases such as cervical spondylopathy.Therefore, people who bends over one's desk working for a long time needs to have a rest on time, strike a proper balance between work and rest, and once continue the time to bend over one's desk working unsuitable long, often work 1 hours usually, just should have a rest 5 to 10 minutes, and the light transhipment doing neck all directions is moved, and allows tired neck be had a rest.But due to operating pressure, or staff's energy concentrate etc. reason, staff easily causes the time forgetting continuous operation, or can not support good work habit, make the one-time continuous operating time long, various disease is easily brought out in long-term work.

Therefore, design a kind of desk lamp control device, can automatically remind the person's of bending over one's desk working continuous working period long, should have a rest in time and do recover motion, and when user leaves the illumination range of desk lamp, automatic distinguishing major part LED lamp bead, dim light, thus make LED desk lamp be in power save mode, this has important using value in the occasion of bending over one's desk working at night.

Summary of the invention

Technical problem to be solved by this invention is, design a kind of intelligent LED desk lamp control device, realize the function of automatically reminding user suitably to have a rest, and when user leaves the effective range of desk lamp illumination, desk lamp can enter power save mode automatically by the mode extinguishing part lamp pearl.

The technical solution adopted in the present invention is: a kind of intelligent LED desk lamp control device, include input through keyboard module (1), human body infrared induction module (2), decision-making treatment module (3), state display and alarm module (4), is characterized in that: described input through keyboard module (1) realizes the setting of stream time upper limit threshold and time of having a rest lower threshold; In the effective range of described human body infrared induction module (2) monitor station light photograph, whether someone enters, and has judged whether that people is at use desk lamp with this; Described decision-making treatment module (3) realizes the decision-making treatment function of system; Described state display and alarm module (4) realize result display and the warning reminding function of system running state.

The measure taked also comprises:

The central processing unit of above-mentioned decision-making treatment module (3) is single-chip microcomputer.

The transducer of above-mentioned human body infrared induction module (2) adopts pyroelectric infrared sensor.

Above-mentioned state display and alarm module (4) adopt LCD liquid crystal display screen show state, adopt warning lamp and buzzer to report to the police.

Above-mentioned input through keyboard module (1) is containing 4 basal keystrokes: function switch key, increment key, depreciation key and reset key, wherein function switch key is attached on the external interrupt pin of single-chip microcomputer, the flag bit of system works is changed, with switched system operation function by the external interrupt triggering single-chip microcomputer.

The object of the invention is to make cheap, the simple intelligent LED desk lamp control device of structure with simple circuit and components and parts.User of service is reminded to quit work by the display of single-chip microcomputer, transducer and state and alarm module, suitably have a rest, contribute to the work habit improving the personnel of bending over one's desk working, and when staff leaves the effective range of desk lamp illumination, desk lamp enters power save mode automatically, has very strong practicality.

Accompanying drawing explanation

Fig. 1 is overall structure figure of the present invention.

Wherein:

1: input through keyboard module 2: human body infrared induction module

3: decision-making treatment module 4: state display and alarm module

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

As shown in Figure 1, control device has input through keyboard module (1), when pressing function switch key and can realize the switching of various setting parameter state and operating state, under setting parameter state, by the set point of rise in value key and the adjustable each parameter of depreciation key, adjustable parameter has stream time upper limit threshold t _maxwith time of having a rest lower threshold t _min.

In working order, in the effective range that control device utilizes human body infrared induction module (2) monitor station light photograph, whether someone occurs, and carries out controlling and decision-making according to following rule:

Rule 1: when human body infrared induction module (2) does not detect that someone occurs, in the effective range of expression desk lamp illumination, nobody bends over one's desk working, decision-making treatment module (3) extinguishes the most lamp pearl of desk lamp, desk lamp is made to be in power save mode, and start rest timer continue timing on the basis of former clocking value, quit work the timing of timer, retains the timing result that it is current.

Rule 2: when human body infrared induction module (2) detects that someone occurs, people is had to bend over one's desk working in the effective range of expression desk lamp illumination, whole lamp pearls of decision-making treatment module (3) some bright desk lamp, startup work timer continues timing on the basis of former clocking value, and stop the timing of rest timer, retain the timing result that it is current.

Rule 3: when the clocking value of the timer that works reaches stream time upper limit threshold, warning mark position is set to 1, sends alarm command.

Rule 4: when the clocking value of rest timer reaches time of having a rest lower threshold t _mintime, the clocking value of the clocking value of rest timer and work timer is all set to 0, is 0 by warning mark position, sends stop alarm instruction.

The running status of system and the result of decision are shown by state and alarm module (4) display provides.

When pressing reset key, warning mark position is set to 0, and the clocking value of work timer and rest timer all sets to 0.

According to the result that human body infrared induction module (2) detects, decision-making treatment module (3) judges whether that someone uses desk lamp to bend over one's desk working, when have people bend over the desk stream time long time, decision-making treatment module (3) will send warning, staff is reminded to have a rest, after personnel leave desk lamp, desk lamp extinguishes most of lamp pearl and is in power save mode.

The invention has the advantages that, control device structure is simple, with low cost, convenient and practical, can be applicable on the common LED desk lamp of office or household.
