The present invention will be further described with reference to the accompanying drawings and examples.

Referring to Fig.1, a kind of SCM Based campus dormitory staircase lamp, including STC single-chip microcontroller 3, the of STC single-chip microcontroller 3 One input terminal is connected with the output end of voltage reduction module 2, and the input terminal of voltage reduction module 2 is connect with the output end of power module 1, STC Second input terminal of single-chip microcontroller 3 is connected with the output end of resistance strain type pressure sensor 4, the third input terminal of STC single-chip microcontroller 3 It being connected with the output end of photosensitive resistance sensor 5, the output end of STC single-chip microcontroller 3 is connected with the input terminal of LED drive module 6, The output end of LED drive module 6 is connected with the input terminal of LED lamp panel 7.

The power module 1 is made of two section charged lithium cells, is STC single-chip microcontroller 3 after being depressured by voltage reduction module 2 It powers with peripheral circuit.

Referring to Fig. 2, in order to detect the brightness of ambient enviroment light, the photosensitive resistance sensor 5 is mounted on campus place Give up the side at 8 top of staircase；Resistance strain type pressure sensor 4 and LED lamp panel 7 are configured to two groups, one group of resistance-strain type pressure Force snesor 4 is mounted in the upper cross bar 9 of campus dormitory staircase 8, and LED lamp panel 7 is mounted under upper cross bar 9, for detecting Pressure change and offer illumination when student lower berth；Another group of resistance strain type pressure sensor 4 is mounted on 8 bottom of campus dormitory staircase On portion's cross bar 10, LED lamp panel 7 is mounted on the other side at 8 top of campus dormitory staircase, pressure change when for detecting student upper berth With offer illumination.

Successively after triggering, LED lamp panel 7 carries out a little the photosensitive resistance sensor 5 and resistance strain type pressure sensor 4 Bright, lighting time is one minute, and only has one group of LED lamp panel 7 to light when each two-berth.

Referring to Fig. 3, the resistance strain type pressure sensor 4 includes triode Q1, and the collector of triode Q1 connects The emitter of GND, triode Q1 are connected with the port P0 of resistance R1, STC single-chip microcontroller 3, and the other end of resistance R1 connects resistance R2 One end, and meet VCC, the other end connection resistance R3 of resistance R2, the one end for straining sheet resistance R4, strain sheet resistance R4's is another Terminate GND, the base stage of the other end connecting triode Q1 of resistance R3；Resistance R1 is 1K Ω, and resistance R2 is 4K7 Ω, and resistance R3 is 4K7 Ω, is detected by pressure change, realizes the acquisition of 3 low and high level of STC single-chip microcontroller.

Referring to Fig. 4, it is contemplated that the intensity of light source should not be set as too high, and it is 12 that 7 numbers of LED lamp panel, which are arranged, in the utility model It is a, it is attached by series-parallel system, carries out Current amplifier using triode SS8550 (PNP type triode) and realize LED light The driving of plate 7.

The working principle of the utility model are as follows:

In order to avoid LED lamp panel 7 is opened when two-berth on daytime, power wastage is caused, photosensitive resistance sensor 5 is switched and is believed Number output port is linked into the input port of STC single-chip microcontroller 3, sets certain threshold size, module ambient light during the day When given threshold is not achieved in brightness, STC single-chip microcontroller 3 exports high level, when student two-berth, resistance-strain type pressure sensing at this time Device 4 is not had an effect, and LED lamp panel 7 is not turned on；For module when at night, ambient brightness reaches given threshold, STC is mono- at this time Piece machine 3 exports low level, and when student two-berth, resistance strain type pressure sensor 4 is had an effect, and LED lamp panel 7 is opened, program In be delayed by delay function, set one minute lighting time of lamp plate, to guarantee student smoothly two-berth.

At night, when student does not have two-berth, triode Q1 conducting, P0 Port detecting to low level passes through software at this time Program setting, LED lamp panel 7 is without lighting, when student two-berth, strain sheet resistance R4 resistance value increase, at this time resistance R2 with Current potential between R4 is got higher, so that triode Q1 is turned off, the current potential of the port P0 becomes high level by low level, passes through program at this time Setting, LED lamp panel 7 are lighted.It is delayed in program by delay function, sets one minute lighting time of lamp plate, from And guarantee student smoothly two-berth.

When simultaneously in order to avoid evening student two-berth, when by upper cross bar 9 and upper cross bar 10, two groups of LED light Plate 7 is all lighted, and power supply is caused to waste, and passes through program setting, when guaranteeing that student passes through upper cross bar 10 at upper berth, dormitory The LED lamp panel 7 at 8 top of staircase is lighted, and lighting time is one minute, LED when by upper cross bar 9, under upper cross bar 9 Lamp plate 7 is without lighting.Student is at lower berth, and when by upper cross bar 9, the LED lamp panel 7 under upper cross bar 9 is lighted, warp When crossing upper cross bar 10, the LED lamp panel 7 at 8 top of dormitory staircase is without lighting.
