1. The working principle of the subsystem:

(1) Power conversion module 1 converts 220V alternating current into 5V direct current to supply power to other modules. The indoor light intensity detection module 3 adopts a photoresistor sensor module to detect the ambient light intensity. The greater the light intensity detected by the indoor light intensity detection module 3, the smaller the analog voltage output by the AO terminal, and vice versa. The indoor light intensity detection module 3 sends the detected ambient light intensity analog signal from its AO end to the microprocessor 5 for A/D conversion into a digital quantity, and the microprocessor 5 divides the ambient light intensity into three parts according to this digital quantity. brightness levels (superbright, brighter, and darker). The light-on-off detection module 4 also adopts a photoresistor sensor module. When the light-tube is off, its DO terminal outputs a high level, otherwise, it outputs a low level. The human body induction module 2 uses the pyroelectric human body infrared sensor module to sense whether there is an active human body within the radius r of the ground under the lamp. The pyroelectric human body infrared sensor module is set to a repeatable trigger mode, and its induction delay time is set to 5 minutes (or longer). If there is an active human body, it outputs a high-level signal that continues the induction delay time to the microprocessor 5. If there is no active human body, it outputs a low-level signal to the microprocessor 5. The 2-way relay module 7 adopts a high-level signal. Flat trigger, that is, when it receives the high level output from the microprocessor 5, the normally open contact is closed and the normally closed contact is disconnected; otherwise, the normally open contact is disconnected and the normally closed contact is closed.

The subsystem has three different operating modes under different ambient brightness levels (superbright, brighter, and darker), as follows:

Working mode 1: When the digital quantity of the light intensity signal detected by the indoor light intensity detection module 3 after the A/D conversion of the microprocessor 5 is less than 400, the system is in the ultra-bright working mode. At this time, 33 of the microprocessor 5 , Terminal 32 outputs a high level signal to control the normally closed contacts of the NC1 and NC2 terminals of the 2-way relay 7 to be disconnected, so that the lamp 1 and lamp 2 are placed in a completely off state, and the human body induction module 2 does not work.

Working mode 2: When the digital quantity of the light intensity signal detected by the indoor light intensity detection module 3 after the A/D conversion of the microprocessor 5 is greater than or equal to 400 and less than 600, the system is in a brighter working mode. The 32 terminal of the processor 5 outputs a high level signal to control the normally closed contact of the NC2 terminal of the 2-way relay 7 to disconnect, so that the lamp 2 is extinguished. At the same time, according to the detection signal sent by the human body induction module 2, the The output signal of terminal 33 controls the normally closed contact of the NC1 terminal of the 2-way relay 7, specifically: situation ①, when there is no human body under the lamp, the 33-terminal of the microprocessor 5 outputs a high level to the IN1 of the 2-way relay module 7 terminal, so that the lamp 1 goes out; in case ②, when there is a moving human body under the lamp, the 33 terminal of the microprocessor 5 outputs a low level to the IN1 terminal of the 2-way relay module 7, so that the lamp 1 is lit.

Working mode 3: When the digital quantity of the light intensity signal detected by the indoor light intensity detection module 3 is greater than or equal to 600 after the A/D conversion of the microprocessor 5, the system is in a dark working mode, and the microprocessor 5 Control the action of the 2-way relay module 7 according to the detection signal sent by the human body sensing module 2, specifically: in the case ①, when there is no human body under the light, the 33 and 32 terminals of the microprocessor 5 output a high level to the 2-way relay module 7. Turn off lamp 1 and lamp 2; in case ②, when there is an active human body under the lamp, the 33 and 32 terminals of the microprocessor 5 output low level to the 2-way relay module 7, so that the lamp 1 and the lamp are 2 is fully on; in case ③, when the human body with activity under the lamp becomes an inactive human body, the output of terminal 33 of the microprocessor 5 remains unchanged (the lamp 1 is lit), and the terminal 32 of the microprocessor 5 outputs a high level Go to the 2-way relay module 7, make the lamp 2 go out first (prompt the person under the lamp to make a slight movement), and delay for 1 minute; if a moving human body is detected within 1 minute of the delay, the microprocessor 5 Terminal 32 outputs a low level to the 2-way relay module 7, so that the lamp 2 lights up again; if there is no human body under the lamp detected after a delay of 1 minute, the output of terminal 33 of the microprocessor 5 becomes high The level is sent to the 2-way relay module 7, so that the lamp 1 is also extinguished, that is, returning to situation ①; if a human body is detected under the lamp after a delay of 1 minute, it returns to situation ②.

Install this subsystem on the lamp socket of each double-tube lighting lamp in the room, and arrange the distance between the lamp sockets reasonably according to the sensing range of the human body sensing module 2, so that it can sense whether there are people in different positions in the room. The control of the three working modes can automatically realize the indoor local lighting control according to the ambient brightness of different indoor positions and whether someone lights up the lamps in the corresponding positions, so as to achieve energy saving.

The sensing range of the human body sensing module 2 is a circular area with a ground radius r. The calculation method of r is as follows:

The installation position of the human body induction module 2 is shown in Figure 3, and the schematic diagram of its sensing range is shown in Figure 4. In Figure 4, the pyroelectric human body infrared sensor module is installed at point O. It can be seen from the manual of the pyroelectric human body infrared sensor module that its The sensing range is a combination of a cone and some spheres. The figure is a cross-sectional view of the sensing range, where three points ABC are on the same circle, AO=BO=3～4 meters, L=5～7 meters, ∠AOB = 100°, adjust the maximum sensing distance of the sensor to L = 7 meters, AO = 4 meters, the installation height of the pyroelectric human body infrared sensor is H = 5 meters from the ground, and r is the range of people on the ground that the sensor can sense. radius. Then the coordinates of the three points ABC are: A(-4sin50°, 0), B(4sin50°, 0), C(0, -7+4cos50°). The coordinates of the three points ABC can determine the equation of the circle, The following formula is obtained: where x is the abscissa of the center Q, y is the ordinate of the center Q, and R is the radius of the circle.

(x+4sin50°) ² +y ² =R ² (1)

(x-4sin50°) ² +y ² =R ² (2)

x ² +(y+7-4cos50°) ² =R ² (3)

From formulas (1), (2) and (3), it can be solved: x=0, y≈-1.15, R≈3.27, then r can be solved as follows:

(2) Use the lamp on-off detection module 4 to detect the on-off of the lamp, and the microprocessor 5 outputs the control signal to the 2-way relay module 7 and the signal input from the lamp on-off detection module 4 to the microprocessor 5 according to the control signal. Determine the working status of the lamp. ①If the output of terminal 33 of the microprocessor 5 is low level (controlling lamp 1 to light) and the input of terminal 9 is high level (detecting that the lamp 1 is off), the microprocessor 5 judges that the lamp Tube 1 is working abnormally. ②If the output of terminal 33 of the microprocessor 5 is low level (controlling lamp 1 to light) and the input of terminal 9 is low level (detecting that the lamp 1 is on), the microprocessor 5 judges that at this time Lamp 1 works fine. ③If the output of terminal 32 of the microprocessor 5 is low level (controlling the lamp 2 to light) and the input of terminal 10 is high level (detecting that the lamp 2 is in an off state), the microprocessor 5 judges that the lamp is at this time. Tube 2 is working abnormally. ④If the output of the 32 terminal of the microprocessor 5 is low level (controlling the lamp 1 to light up) and the input of the 10 terminal is low level (detecting that the lamp 2 is in the lighting state), the microprocessor 5 judges that at this time Lamp 2 works fine. By analogy, when the output signals of the 33 and 32 terminals of the processor 5 control a certain lamp to turn off, and the lamp on-off detection module 4 actually detects that the lamp is still on, the lamp works abnormally, otherwise the lamp The tube works fine.

(3) When the lighting/extinguishing state of the lamp or the normal/abnormal working state changes, the microprocessor 5 attaches the new state information of the lamp lighting/extinguishing and normal/abnormal operation to the subsystem through the power carrier module I6 ID (each subsystem sets a unique ID to identify different subsystems) and then sends it to the main system.

2. The working principle of the main system:

The power carrier module II9 in the main system receives the new status information of the normal/abnormal working status and on/off of the lamp carrying the subsystem ID from the subsystem power carrier module I6 through the 220VAC power input line 12, and transmits this information. The information is transmitted to the computer 11 through the TTL to USB module 10, and the information is displayed on the computer 11. When any lamp tube in the N subsystems is abnormal, the main system computer 11 issues an alarm, prompting the staff to repair it in time. In addition, the staff can send out the control signal carrying the subsystem ID through the computer 11 to turn on/off any lamp in the N subsystems. The line 12 is sent to the subsystem power carrier module I6 and then sent to the microprocessor 5. The microprocessor 5 extracts the subsystem ID from the main system control signal and compares it with its own subsystem ID. If it is inconsistent, it will not do any processing. Then, according to the control signal sent by the main system, the control signal is output to the 2-way relay module 7 to control the lighting/extinguishing of lamp 1 or lamp 2 in the subsystem.

The working process of the present utility model is as follows:

After the system is powered on, the indoor light intensity detection module 3 uses the photoresistor sensor module to detect the ambient light intensity and converts it into a voltage analog output from its AO terminal to the 11 terminal of the microprocessor 5. The microprocessor 5 uses its internal A 10-bit A/D converter converts this voltage analog to digital. The microprocessor 5 divides the ambient light intensity into three brightness levels according to this digital quantity: when this digital quantity is less than 400, the ambient brightness level is super bright, and the subsystem is in super bright working mode; when this digital quantity is greater than or equal to 400 And when it is less than 600, the ambient brightness level is brighter, and the subsystem is in a brighter working mode; when the number is greater than or equal to 600, the ambient brightness level is darker, and the subsystem is in a darker working mode. The human body induction module 2 uses the pyroelectric human body infrared sensor module to sense whether there is an active human body within the radius r of the ground under the lamp. The pyroelectric human body infrared sensor module is set to a repeatable trigger mode, and its induction delay time is set to 5 minutes (or longer), that is, when an active person is detected, the OUT terminal of the human body sensing module 2 outputs a high level to the 23 terminal of the microprocessor 5, and this high-level signal can be maintained for 5 minutes (or longer). ), if there is no moving human body, the OUT terminal of the human body sensing module 2 outputs a low-level signal to the terminal 23 of the microprocessor 5 . The lamp on/off detection module 4 is composed of two photoresistor sensor modules. The lamp on/off detection module 4-1 detects the state of the lamp 1. When the lamp 1 is lit, its D0 terminal outputs a low level to the 9 terminal of the microprocessor 5, otherwise, it outputs a high level to the microprocessor terminal 9 of device 5. The lamp on/off detection module 4-2 detects the state of the lamp 2. When the lamp 2 is lit, its D0 terminal outputs a low level to the 10 terminal of the microprocessor 5, otherwise it outputs a high level to the microprocessor 5 of the 10 end.

When the ambient brightness level is super bright, the subsystem is in super bright working mode. The microprocessor 5 does not process the signal from the terminal 23 of the microprocessor 5 input by the human body sensing module 2 . At the same time, the 33 and 32 terminals of the microprocessor 5 output high level to the IN1 and IN2 terminals of the 2-way relay module 7, so that the normally closed contacts of the NC1 and NC2 terminals in the 2-way relay module 7 are disconnected, and the lamp 1 and the lamp are disconnected. The power supply circuit of tube 2 is disconnected, so that both lamp 1 and lamp 2 are extinguished.

When the ambient brightness level is brighter, the subsystem is in a brighter operating mode. The 32 terminal of the microprocessor 5 outputs a high level to the IN2 terminal of the 2-way relay module 7, so that the normally closed contact terminal of the NC2 terminal inside the 2-way relay module 7 is disconnected, and the power supply circuit of the lamp 2 is disconnected, so that the lamp 2 is extinguished. . At the same time, the microprocessor 5 detects the signal input from the OUT end of the human body sensing module 2 at its 23 end. ①If the microprocessor 5 detects that the input of terminal 23 is low level (when there is no active person under the light), the terminal 33 of the microprocessor 5 outputs a high level to the IN1 terminal of the 2-way relay module 7, so that the 2-way The normally closed contact of the NC1 terminal inside the relay module 7 is disconnected, the power supply circuit of the lamp 1 is disconnected, and the lamp 1 is extinguished. ② If the microprocessor 5 detects that the input of the 23 terminal is high (when there is an active person under the lamp), the 33 terminal of the microprocessor 5 outputs a low level to the IN1 terminal of the 2-way relay module 7, so that the 2-way The normally closed contact of the NC1 terminal inside the relay module 7 is closed, and the power supply circuit of the lamp 1 is connected, so that the lamp 1 is lit.

When the ambient brightness level is dark, the subsystem is in dark operating mode. At this time, the microprocessor 5 detects the signal input from the OUT end of the human body sensing module 2 at its 23 end. Situation ①: If the microprocessor 5 detects that the input of terminal 23 is low level (when there is no active person under the light), then the terminals 33 and 32 of the microprocessor 5 output a high level to IN1 and IN1 of the 2-way relay module 7 The IN2 terminal makes the normally closed contacts of the NC1 and NC2 terminals in the 2-way relay module 7 disconnected, the power supply circuit of the lamp 1 and the lamp 2 is disconnected, and the lamp 1 and the lamp 2 are extinguished. Situation ②: If the microprocessor 5 detects that the input of the 23 terminal is high level (when there is an active person under the lamp), then the 33 and 32 terminals of the microprocessor 5 output a low level to the IN1 and the 2-way relay module 7. The IN2 terminal closes the normally closed contacts of the NC1 and NC2 terminals in the 2-way relay module 7, and the power supply circuit of the lamp 1 and the lamp 2 is connected, so that the lamp 1 and the lamp 2 are lit. Situation ③: If the microprocessor 5 detects the transition of the input of terminal 23 from high level to low level (when there is an active person under the lamp to an inactive person), then the output of terminal 33 of the microprocessor 5 unchanged (lamp 1 is lit), the 32 terminal of the microprocessor 5 outputs a high level to the IN2 terminal of the 2-way relay module 7, so that the normally closed contact of the NC2 terminal of the 2-way relay module 7 is disconnected, and the lamp 2 When the power supply circuit is disconnected, the lamp tube 2 is turned off first to remind the person under the lamp to make slight movements. At the same time, the microprocessor 5 delays for 1 minute; if the microprocessor 5 detects the transition from the low level to the high level of the input of the 23 terminal within the delay of 1 minute (the inactive person under the lamp becomes active time), then the 32 port of the microprocessor 5 outputs a low level to the IN2 terminal of the 2-way relay module 7, so that the normally closed contact of the NC2 terminal connected to the 2-way relay module 7 is closed, and the power supply circuit of the lamp 2 is connected. Turn lamp 2 on again. After a delay of 1 minute, if the microprocessor 5 detects that the input of terminal 23 is low level (when there is no active person under the light), the terminal 32 of the microprocessor 5 outputs a high level to IN1 of the 2-way relay module 7 end, the normally closed contact of the NC1 end of the 2-way relay module 7 is disconnected, and the power supply circuit of the lamp 1 is disconnected, so that the lamp 1 is also extinguished, that is, return to the situation ①; if the microprocessor 5 detects that the input of the 23 terminal is high level (there is an active person under the light), then return to situation ②.

During the working process of the system, the lamp on/off detection module 4 continuously detects the on/off status of the lamp 1 and the lamp 2 and detects the on/off status of the lamp from the lamp on/off detection module 4-1 and the lamp on/off detection module 4-2 respectively. The D0 terminal outputs signals to the 9 and 10 terminals of the microprocessor 5 . The microprocessor 5 judges that the lamp is working normally/abnormally according to the output signals of terminals 33 and 32 and the input signals of terminals 9 and 10 when it is working: ①If the output of terminal 33 of the microprocessor 5 is low level (controlling lamp 1 to light up) ) and the input of terminal 9 is a high level (it is detected that the lamp tube 1 is in an off state), then the microprocessor 5 judges that the lamp tube 1 is working abnormally at this time. ②If the output of terminal 33 of the microprocessor 5 is low level (controlling lamp 1 to light) and the input of terminal 9 is low level (detecting that the lamp 1 is on), the microprocessor 5 judges that at this time Lamp 1 works fine. ③If the output of terminal 32 of the microprocessor 5 is low level (controlling the lamp 2 to light) and the input of terminal 10 is high level (detecting that the lamp 2 is in an off state), the microprocessor 5 judges that the lamp is at this time. Tube 2 is working abnormally. ④If the output of the 32 terminal of the microprocessor 5 is low level (controlling the lamp 2 to light up) and the input of the 10 terminal is low level (detecting that the lamp 2 is on), the microprocessor 5 judges that at this time Lamp 2 works fine. By analogy, when the output signals of the 33 and 32 terminals of the processor 5 control a certain lamp to turn off, and the lamp on-off detection module 4 actually detects that the lamp is still on, the lamp works abnormally, otherwise the lamp The tube works fine.

During the working process of the system, when the microprocessor 5 detects that the input signals at the 9th and 10th ends (the status of the lamp on/off) changes, or when the microprocessor 5 judges that the lamp works normally/abnormally occurs. When changing, the microprocessor 5 attaches the new status information of the current lamp (the status information of the lamp on/off and the status information of the lamp working normally/abnormally) through the 22 (TXD) terminal, and then attaches the subsystem ID (each subsystem device set a unique ID to identify different subsystems), and send it to the RX end of the power carrier module I6. The power carrier module I6 sends the new status information of the lamp carrying the subsystem ID to the main system through the 220VAC power line 12. The power carrier module II9, the TX terminal of the power carrier module II9 will then send the received new status information of the lamp carrying the subsystem ID to the RXD terminal of the TTL to USB module 10, and the TTL to USB module will receive the RXD terminal. After the TTL level signal is converted, the new status information of the lamp carrying the subsystem ID is sent to the computer 11 through the USB port of the computer 11, and the computer 11 updates and displays the on/off status of each lamp in the corresponding subsystem or In normal/abnormal state, and if any lamp in the N subsystems is in an abnormal state, the computer 11 sends out an alarm message to prompt the management personnel to repair the lamp in time.

During the working process of the system, when the administrator needs to remotely control the lighting/extinguishment of any lamp in the N subsystems, the administrator can send the control of any lamp in the subsystem carrying the subsystem ID through the computer 11. Signals, for example: when the manager needs to turn on/off the lamp 1 in a certain subsystem, the computer 11 can send out a control signal to turn on/off the lamp 1 carrying the ID of a certain subsystem, and the control signal is passed through the computer. 11 is sent out from the USB port, and after being converted into a TTL level signal by the TTL to USB module 10, it is transmitted from the TXD end of the TTL to USB module 10 to the RX end of the power carrier module II9. The control signal carrying a certain subsystem ID is sent to the subsystem power carrier module I6, and the TX end of the power carrier module I6 sends the received control signal carrying a certain subsystem ID from the main system to 21 ( RXD) terminal. After the microprocessor 5 receives the control signal (turning on/off the lamp 1) carrying a certain subsystem ID, it extracts the subsystem ID in the control signal and compares it with its own subsystem ID. If it is inconsistent, it will not do any processing. If they are consistent, output a signal (low level/high level) from terminal 33 to the IN1 terminal of the 2-way relay module 7 according to the control signal, so that the normally closed contact at the NC1 end of the 2-way relay module 7 is closed/disconnected. The power supply circuit of the lamp 1 is turned on/off, so that the lamp 1 is turned on/off. By analogy, the administrator can also remotely control the lighting/extinguishment of lamp 2 in a subsystem manually from the main system, or manually control the lighting/extinguishment of lamp 1 and lamp 2 in a subsystem at the same time. In this way, the computer 11 in the main system can manually control the lighting/extinguishment of any lamp in the N subsystems remotely.
