The utility model discloses a circuit of radar type automatic control lamp, which comprises a microcontroller, and a light detection circuit, a radar signal circuit, a power circuit, a reset circuit and a lamp panel drive circuit which are respectively connected with the microcontroller;
the power supply circuit is respectively connected with the microcontroller, the light detection circuit, the radar signal circuit, the reset circuit and the lamp panel driving circuit;
the lamp panel driving circuit is connected with the lamp; the light detection circuit is connected with the photoresistor; the radar signal circuit is connected with a radar.
The microcontroller adopts PIC16F886 chip, 1 pin connects reset circuit, 9 pins, 10 pins connect clock circuit that crystal oscillator and electric capacity constitute, 12 pins connect lamp plate drive circuit, 21 pins connect radar signal circuit, 26 pins connect light detection circuitry.
The LIGHT detection circuit is connected with a photoresistor through an interface J1, and the LIGHT end is connected with the microcontroller;
in the radar SIGNAL circuit, a SIGNAL end is connected with a radar, the SIGNAL end is connected with a P-channel field effect transistor SI2301 through a resistor R1, and the P-channel field effect transistor is connected with a microcontroller;
the reset circuit adopts an SOT23-TCM809L chip, and the CPU _ RST end of the reset circuit is connected with the microcontroller;
the lamp panel driving circuit adopts a TLP521 chip which is connected with an N-channel field effect tube IRFZ44N,
the N-channel field effect transistor is connected with the lamp through an interface P1, and the OUT end is connected with the microcontroller.
The lamp panel driving circuit has a SIGNAL input terminal SIGNAL terminal.
The interface J3 is for downloading a program.
Interface P1 is the interface of inserting the lamp plate for connect the LED lamp.
The radar is an external module, which is commercially available and is connected to the circuit.
The P-channel field effect transistor Q1 functions: the signal voltage signals are matched.
The reset chip is a TCM1 chip SOT23-TCM809L and is used for monitoring the power supply voltage, and when the voltage is relatively low, the CPU RST can generate a reset signal to prevent programs from being unstable. No reset key is required.
In the light detection circuit, a light sensitive resistor is arranged on the interface J1, the light sensitive resistor can change according to the intensity of external light, and the microcontroller can control the on and off of the lamp according to the light intensity of the light sensitive resistor.
The radar signal circuit is characterized in that a radar module is bought and connected to the radar signal circuit, if a radar detects a person, the radar outputs a signal to a P-channel field effect transistor Q1, then the signal is sent to a microcontroller, and finally a lamp panel driving circuit and a lamp are started to illuminate by a mainboard (microcontroller) according to the fact that the person is absent.
Lamps and lanterns can adjust luminance through lamp plate drive circuit, and the principle of adjusting luminance: the lamp is an LED lamp tube, and the width of the pulse width is controlled by generating a rectangular pulse wave, and the waveform of the rectangular pulse wave controls the width of the pulse width, so that if the pulse width of the lamp is wider, the lamp is brighter, and if the pulse width of the lamp is narrower, the lamp is darker.
To sum up, the functions of the three parts are that when light exists, the light intensity reaches a certain degree, and no matter people exist nearby, the light cannot be lightened under the control of the processor. When the outside light is dark to a certain degree and the radar detects that a person is present, the processor controls the lamp to gradually brighten. In a dim state, the light is not too bright. When it is at night, the processor will gradually turn on the light. The darker the light, the brighter the lamp. There is no need to detect sound.
The signal end that radar signal circuit connects, the signal that the radar sent, after voltage matching handles to INT0, after finishing through microcontroller (singlechip) processing, judge according to these condition singlechips of photoresistor signal and finish together, drive lamp plate drive circuit and lamps and lanterns through the OUT terminal again. A signal end in the lamp panel driving circuit is a reserved interface, if other sensors are used for forming the trigger signal, a single chip microcomputer is not used, but a resistor R9 and the signal end are not needed in the circuit diagram at present.
The utility model discloses a circuit of radar type automatic control lamps and lanterns had both possessed photosensitive detection, had the radar detection again, can adjust luminance through the PWM mode in addition.
PWM generally refers to pulse width modulation. The pulse width modulation is an analog control mode, and the bias of the base electrode of the transistor or the grid electrode of the MOS transistor is modulated according to the change of the corresponding load, so that the conduction time of the transistor or the MOS transistor is changed, and the output of the switching voltage-stabilized power supply is changed. Pulse width modulation enables the output voltage of the power supply to remain constant as operating conditions change, a very effective technique for controlling analog circuits using the digital signal output of a microprocessor.
