Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, circuit of the present invention comprises: single-chip minimum system module, inclination angle induction module, photosensitive trigger module, the solar powered module of pressure activated module, some matrix LED display module and sensitive switch; Solar panels absorb solar energy, change into unsettled electric energy, CN3083 chip stabling current and by electrical power storage in storage battery, CN5136 chip boosts, and obtains 5V stabilized power supply; Photo resistance sensing light is strong and weak to be changed, and along with light intensity decreasing, it is large that resistance becomes, and connects LM339 comparator voltage and becomes the large and final reference level that surpasses, and causes output voltage upset and is discovered This move by single-chip microcomputer, realizes photosensitive triggering; Pressure sensor sensed pressure changes, and connects comparator, produces upset when voltage surpasses threshold voltage, produces threshold values signal, realizes pressure activated; Obliquity sensor SCA60C is along with the variation at inclination angle, output voltage also changes thereupon, connect the two voltage comparators of LM393, by analog quantity voltage signal with compare with reference to fixed voltage, near equating in the two amplitude, output voltage produces transition, corresponding output high level or low level, trigger Single Chip Microcomputer (SCM) program, control point matrix LED shows corresponding left-hand rotation right-hand rotation icon.
As shown in Figure 2, mainboard comprises single-chip minimum system, irritated trigger module, RS232 serial communication circuit, power supply stabilization circuit, and four external binding posts.In single-chip minimum system, single-chip microcomputer is STC89C51.14 pin, 15 pin are connected to oscillating circuit, and wherein crystal oscillator frequency is 11.0592MHz.When adding the required DC power supply of work to single-chip microcomputer, oscillator gets up with regard to starting oscillation.The object of oscillating circuit is to provide required clock pulse signal for single-chip microcomputer work.Wherein 14 pin and 15 pin have connect respectively the electric capacity of a 47pF over the ground, and object is to prevent single-chip microcomputer self-excitation.Simultaneously, at 4 pin namely RST end is an external reset circuit, object is that single-chip microcomputer is powered on while starting working, and internal circuit is started working from initial condition.In photosensitive triggering system, used the output voltage values of a comparator LM339 inspection photo resistance, potentiometer R2 is a voltage divider, its centre tap provides a reference level Vp to 4 pin of comparator LM339, when output valve surpasses reference level, LM339 changes the state of output Vout, produces threshold voltage.RS232 serial communication circuit is used MAX232 chip to carry out serial communication, uses USB to turn 232 connecting lines system is connected with computer, in Keil software, downloads, and carries out burning.In power supply stabilization circuit, use ASM1117 chip burning voltage, connect afterwards PWR2.5 Direct current power source socket for connecting solar energy movable power supply.
As shown in Figure 3, whole solar power supply circuit is comprised of CN3083 and two chips of CN5136.VCC end (4 pin) access solar panel at CN3083 chip absorbs solar energy, and now solar energy enters from 4 pin, adds capacitor C 1 to make stabilized input voltage.The BAT end (5 pin) of CN3083 chip connects battery, and BAT pin provides charging current and constant voltage charge voltage to battery, in charging process, by power storage in battery.BAT also has sleep pattern simultaneously, when supply voltage latchs threshold value or sleep pattern lower than supply voltage is too low, now VCC (4 pin) is less than 20mV with the voltage difference of BAT pin, and CN3083 will enter the sleep pattern of low-power consumption, and now the electric current of BAT pin is less than 3 μ A.In charging process, CH pin (7 pin) is moved to low level by internal switch, and now red LED lamp is bright.When charging finishes, OK pin (6 pin) is moved to low level by internal switch, and now green LED lamp is bright.From the supply voltage of CN3083 output, be now 3-4V, also need a booster circuit, access CN5136 chip.Electric current flows into CN5136 chip from the output of CN3083 chip, adds inductance and Schottky diode can affect to a great extent conversion efficiency, and inductance and output capacitance can affect the ripple of output voltage.Inductance value is less, and output current ability is stronger, and output ripple is also larger.Capacitor C 3, input filter; Capacitor C 5, output filtering, is used the smaller electric capacity of series equivalent resistance (ESR), can ensure less ripple; Capacitor C 4, loop compensation electric capacity, can reduce ripple and noise.Resistance R 3 arranges output voltage with R4.
As shown in Figure 4, pressure sensor produces the analog voltage of 0～4.7V, and wherein, along with the increase of pressure, output voltage also increases thereupon.When pressure increases to certain value, surpass the rated voltage of comparator, there is reversion and caught by single-chip microcomputer, according to command adapted thereto, produce corresponding actions.
As shown in Figure 5, in the sensing module of inclination angle, transducer SCA60C can accurately detect the angular range of 0～90 degree, when angular transducer becomes the angle of 90 degree with horizontal plane, and the analog voltage of output+5V now.Within the scope of the inclination angle of 0～90 degree, the analog voltage signal that is proportional to size+0.5, inclination angle～+ 5V of output, when the range of the angle between angular transducer and horizontal plane from 90 degree to 180 degree, output output be the analog voltage signal from+change to successively+0.5V of 5V, therefore by the size of determination sensor SCA60C output end voltage, can determine the angle of transducer and horizontal plane.In the sensing module of inclination angle, make the two voltage comparators of LM393, an analog quantity voltage signal and one are compared with reference to fixed voltage, near equating in the two amplitude, output voltage will produce transition, corresponding output high level or low level.
As shown in Figure 6, the 16*16 dot matrix that LED display module is comprised of four 8*8 common anode dot matrix.Drive part is used the 74HC595 of two displacement tape storages and two memory 74HC164 to form.74HC595 is responsible for line scanning data, and 74HC164 is responsible for column scan data.Column scan adopts triode amplified current, adds the intensity that exposes thoroughly, and improves dot matrix screen brightness.Whole procedure for displaying is for first shifting out 16 column data signals, then moves a row signal, finally repeated 16 line scannings.
