Embodiment
As Fig. 1 and Fig. 2, a kind of myopia prevention with light consumption prompter it is characterised in that：Including the transmitting mould being electrically connected with successively
Block, receiving circuit 3 and control alarm module, wherein, described transmitter module includes multi-resonant oscillating circuit 1 and radiating circuit 2, transmitting
Circuit 2 includes three groups of infrared transmitters in parallel, and multi-resonant oscillating circuit 1 is electrically connected with radiating circuit 2, drives infrared transmitter
Send certain infrared light by required；Described receiving circuit 3 includes the infrared receiving diode of three groups of series connection, infrared receiver two pole
Pipe is corresponded with infrared transmitter and is horizontally disposed with；Described control alarm module includes reset circuit 4, clock oscillation circuit 5, master
Controller 6 and sound light alarming circuit 7, reset circuit 4, clock oscillation circuit 5 are all connected with the input of master controller 6, clock
Oscillating circuit 5 will provide clock oscillation signal to single-chip microcomputer, and reset circuit 4 effect is by whole Circuits System replacement work,
Here can also use as system reset status key.The outfan of master controller 6 is connected with sound light alarming circuit 7, described
Sound light alarming circuit 7 includes speaker and display lamp.
In the present embodiment, described multi-resonant oscillating circuit 1 is mainly made up of 555 intervalometers, can get preferable transmission distance
From with reliable and stable performance；Described master controller 6 is single-chip microcomputer.
In the present embodiment, the operating frequency of described multi-resonant oscillating circuit 1 is 38kHz, makes the work frequency of infrared transmitter
Rate is the most suitable operating frequency, and then can get preferable transmission range and the reliable performance of safety and stability.Described master controller 6 is
MCS-51 single-chip microcomputer.
In the present embodiment, described 555 intervalometers are connected with infrared transmitter by filter amplification circuit, can strengthen infrared
The transmission power of emitter；Described infrared receiving diode passes through the reception pin phase of filter and amplification rectification circuit and single-chip microcomputer
Even, stability and the accuracy of circuit can be improved as far as possible.
In the present embodiment, described speaker is buzzer, and described display lamp is LED display lamp.
In the present embodiment, described LED display lamp includes two different colors of LED display lamp, respectively green and red
Color.
As Fig. 3 and Fig. 4, the multi-resonant oscillating circuit 1 that the drive signal of radiating circuit 2 is made up of 555 intervalometers drives, then leads to
Oscillator signal is amplified by the amplifying circuit crossing audion composition, to strengthen the transmission power of infrared transmitter with this.
As Fig. 5, receiving circuit 3 is amplified to receipt signal using two-stage transistor amplifier, is entered with electric capacity simultaneously
Row filtering, accurate enough with the signal received by ensureing.Receipt signal can be turned after the filtering and rectification of receiving circuit 3
Become control voltage signal.
As Fig. 6 and Fig. 7, in receiving circuit 3 normal work, each test point normally can receive infrared ray, connects
Receive circuit 3 and then can send a low level signal to master controller 6, sound light alarming circuit 7 is in normal detection state：Green
LED will light.When the sitting posture because lean forward of user changes, in the middle of multi beam light-metering point at least one because user
Block and do not receive Infrared, now receiving circuit 3 will send a high level signal, when in three groups of monitoring points at least
Two groups when sending high level signal, sound light alarming circuit 7 works：Red LED will be lighted and buzzer can send similar to
The chimes of doom of siren.
As Fig. 7, carry out emulation experiment to controlling alarm module：
Here the emulation carrying out utilizes button simulation to control received photosignal, green LED lamp during normal work
Light, according to the instruction state of work light, reader can determine whether device normally works.When reader crosses command range,
Be equivalent to button to press, at this moment P1.7 pin can receive a high level signal, when at least two groups in three groups of monitoring devices
When all receiving high level signal, detection program will require execution according to program, produces first time call subroutine here
Low and high level continues the square-wave signal of 90us, will enter in the middle of second subprogram, as in the previous after executing 100 cycles altogether again
At this moment the square-wave signal that low and high level continues 120us can be produced, at this moment buzzer and LED display lamp can provide alarm signal, lead to
Cross P1.5, P1.6, P1.7 mouth receipt signal, P2.0, P2.1 mouth is controlled to sounding alarm device providing warning with this and carries
Wake up.
Be provided with delay procedure in warning system, when someone has blocked grating region, warning circuit will not work at once and
It is to carry out signal sampling again if it is determined that errorless really reader head is too low in time delay after about 5 seconds, then warning circuit
Will report to the police.When because some unexpected situations block grating regional time's system and also will not undying report to the police, arrange here
The warning reminding of 2000 times, if alarm can not be closed during this period, then system will enter resting state, user under
Will task again after secondary rebooting device.
As shown in fig. 7, the positive pole of passive piezoelectric type buzzer is connected to above the colelctor electrode C of audion, the negative pole of buzzer
Ground connection, will drive buzzer sounding by single-chip microcomputer P2.0 mouth output pulse waveform, Q1 pipe here is that voltage is put
Greatly buzzer sounding is preferably driven with this, then buzzer can be changed by the pulsewidth changing output waveform and send difference
The sound of frequency.
As can be seen from Figure 7 replace the signal that three monitoring points are monitored here with three buttons, when the normal work of circuit
When making, tri- feet of P1.5, P1.6, P1.7 are all low level, when any one monitoring point monitors alarm signal, then corresponding
Pin will be changed into high level.When have more than two will provide alarm signal when receiving high level, improve further
The accuracy of device work.
Those of ordinary skill in the art it should be appreciated that above embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, the change as long as in the spirit of the present invention, to embodiment described above
Change, modification all will fall in scope of the presently claimed invention.
