Specific embodiment

In order to become apparent from illustrating this utility model, further describe below in conjunction with embodiment and accompanying drawing of the present utility model Technical scheme.

As described in Figure 1, a kind of classroom information gathering of this utility model and light dispensing intelligence control system, including being divided into master Machine module and slave module.Host module is placed in main control room, slave modules house between each classroom, each slave module Communicated to connect by serial bus with host module.Slave module includes Single Chip Microcomputer (SCM) system and the connected RC522 brushes of difference Card circuit module, OLED display circuit modules, lighting control circuit module, key-press module, are also included for above-mentioned each module for power supply Power module.The host module also includes OLED display circuit modules, the key-press module of Single Chip Microcomputer (SCM) system and its connection, with And power module.

As shown in Fig. 2 for the fundamental diagram of intelligence control system, when slave circuit module of swiping the card has detected student and enters When entering classroom, judge that whether the student enters correct classroom according to pre-set class school timetable of attending class, if not then carrying Show that the student enters the classroom of mistake or this period there is not class, if it is record the time at that time, can in host module To inquire about the one week interior time for entering classroom of the student, can be as the reference of classroom work attendance of teaching, while slave mould using this Tuber intelligently provides a kind of scheme of light dispensing according to the number in classroom at this stage.Host module can also inquire about each classroom Occupancy situation, period that accordingly can be idle in the classroom carry out reservation of classroom.The display circuit module is aobvious using OLED Show circuit module, for showing that attend class occupancy situation, student of time, classroom swipes the card into classroom time and classroom lighting dispensing feelings Condition.

In being embodied as, as shown in figure 3, the Single Chip Microcomputer (SCM) system adopts MSP430F149, it is connected with MSP430F149 Crystal oscillating circuit.C1, C2, Y1 constitute single-chip microcomputer crystal oscillating circuit, XT2IN termination 54 feet of single-chip microcomputer, XT2OUT termination 51 feet of single-chip microcomputer. MSP430F149 microcontrollers carry RC agitators, can realize being used as system clock source by software, but receive external factor Temperature change, pressure change etc. affect larger, so as to cause system unstable in running, and can not provide high frequency The clock of rate, it is impossible to which meeting some needs high-frequency situation.Therefore external crystal-controlled oscillation is adopted as the clock source of microcontroller, it is both full The operation of pedal system clock stable ground can also meet the situation of needs high frequency clock.

As shown in figure 4, the circuit module of swiping the card is using the contactless read-write card chip RC522 of short distance, detection statistics Into student's quantity in classroom.1,2,3,4,5,6,7,8 pins of RC522 connect the P27 of single-chip microcomputer, P26, P25, P21, sky respectively Foot, GND, P23,3.3V pin.The modular circuit can reduce interference of the higher hamonic wave to signal, while improving the biography of PCB antenna Defeated power.In the system application, by SDA, SCK, MOSI and MISO of RC522 P27 respectively with MSP430F149, P26, P25, P21 are connected.MCU is communicated by SPI interface and RC522.

Fig. 5 is the button adjustment module schematic diagram of host module and slave module, and P10, P11, P12, P13 of single-chip microcomputer divide Other and R1, R2, R3, R4, VCC composition pull-up circuit.When S1, S2, S3, S4 are pressed, pull-down circuit is constituted again.

Fig. 6 be embodiment in host module and slave module power module schematic diagram, system power supply need+5V and+ 3.3V power supply.Main power is by+12V storage battery power supplies, the voltage stabilizing of tri- sections of linear voltage stabilization chip compositions of Jing L7805CV and LM1117 Circuit exports stable+5V and+3.3V voltages respectively.In the mesh that the input/output terminal series capacitance of each three-terminal voltage-stabilizing chip is grounded Be reduce output voltage ripple.Its maximum output current is 1A, meets the power needed for whole system.

Fig. 7 is the lighting control circuit module diagram of slave module in embodiment.4 rows illumination is had in each classroom Lamp, P40, P41, P42, P43 are the control end of every row's illuminating lamp respectively, are connected to 4 I/O ends of MSP430F149 main control chips Mouthful.TIP41 is NPN type large power triode, the maximum current of Ic up to 6A, the needs of 100mA when fully meeting practical application. The colelctor electrode and illuminating lamp of TIP41 are connected and+5V power supplys are connected to, base series current-limiting resistance is connected to MSP430F149 controls Port processed, grounded emitter.The signal light control input/output port output high level of MSP430F149, TIP41 colelctor electrodes and transmitting Pole turns on, and illuminating lamp is bright, and input/output port output low level, TIP41 collector and emitters disconnect, and illuminating lamp goes out.When having three When student within row is in classroom, row's illuminator of first row is opened in only control, when there is student of half or so in classroom, Row's illuminator of front two row is opened in control, when student almost occupies classroom, opens all illuminating lamps, and such student also to the greatest extent can may be used Can be sitting in front row, increase the focus attended class.

Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with technique People will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.It is all According to the modification done by the spirit of this utility model main technical schemes, should all cover in protection domain of the present utility model Within.
