The utility model discloses a theory of operation is:

the utility model discloses a subsystem and main system, subsystem can have N, and every subsystem sets up a unique ID, and N is 8 quantity of indoor lighting lamp. The subsystem controls the work of the illuminating lamp according to the light intensity information and the human activity information around the lamp holder, which are acquired by the indoor light intensity detection module and the human body induction module, so that three different illuminating lamp working modes are realized, and the local illumination control is realized, thereby achieving the purpose of saving electric energy. The subsystem can collect the current lighting/extinguishing state of the lamp tube, further judge whether the lamp tube works normally or abnormally, add the subsystem ID to the current working normal/abnormal and lighting/extinguishing state information of the lamp tube, transmit the information to the main system for display, and send out an alarm in the main system when any lamp tube works abnormally to prompt a worker to overhaul. In addition, the on/off of any lamp tube in the N subsystems can be manually and remotely controlled by a computer in the main system.

1. The working principle of the subsystem is as follows:

(1) the power conversion module 1 converts 220V alternating current into 5V direct current to supply power for other modules. The indoor light intensity detection module 3 adopts a photoresistor sensor module and is used for detecting the ambient illumination intensity, the larger the light intensity detected by the indoor light intensity detection module 3 is, the smaller the analog voltage output by the AO end is, and otherwise, the larger the analog voltage is. The indoor light intensity detection module 3 sends the detected ambient light intensity analog quantity signal to the microprocessor 5 from the AO end of the indoor light intensity detection module, and the microprocessor 5 converts the ambient light intensity into digital quantity through A/D conversion, and the microprocessor 5 divides the ambient light intensity into three brightness levels (ultra-bright, bright and dark) according to the digital quantity. The lamp tube on-off detection module 4 also adopts a photoresistance sensor module, when the lamp tube is off, the DO end outputs high level, otherwise, the DO end outputs low level. The human body induction module 2 can induce whether a movable human body exists in the range of the radius r of the ground below the lamp by utilizing the pyroelectric human body infrared sensor module, the pyroelectric human body infrared sensor module is set to be in a repeatable triggering mode, and the induction delay time is set to be 5 minutes (or longer). If there is an active human body, it outputs a high level signal for sensing the delay time to the microprocessor 5, and if there is no active human body, it outputs a low level signal to the microprocessor 5. The 2-path relay module 7 is triggered by high level, namely when receiving the high level output by the microprocessor 5, the normally open contact is closed and the normally closed contact is opened, otherwise, the normally open contact is opened and the normally closed contact is closed.

The subsystem has three different modes of operation in different ambient light levels (super bright, brighter and darker), as follows:

the first working mode is as follows: 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 an ultra-bright working mode, at the moment, the 33 and 32 ends of the microprocessor 5 output high level signals to control the normally closed contacts at the NC1 and NC2 ends of the 2-way relay 7 to be disconnected, so that the lamp tube 1 and the lamp tube 2 are placed in a complete extinguishing state, and the human body induction module 2 does not work.

And a second working mode: 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, at this time, the 32 end of the microprocessor 5 outputs a high level signal to control the normally closed contact at the NC2 end of the 2-way relay 7 to be disconnected, so that the lamp tube 2 is extinguished, and meanwhile, according to the detection signal sent by the human body induction module 2, the 33 end of the microprocessor 5 outputs a signal to control the normally closed contact at the NC1 end of the 2-way relay 7, specifically: under the condition that no active human body exists under the lamp, the 33 end of the microprocessor 5 outputs high level to the IN1 end of the 2-path relay module 7, so that the lamp tube 1 is extinguished; secondly, when a movable human body exists under the lamp, the 33 end of the microprocessor 5 outputs a low level to the IN1 end of the 2-path relay module 7, so that the lamp tube 1 is lightened.

And a third working mode: when the light intensity signal that indoor light intensity detection module 3 detected was greater than or equal to 600 through the digital quantity behind microprocessor 5's the AD conversion, the system was in darker mode, and microprocessor 5 sent the detection signal control 2 way relay module 7 actions according to human response module 2 this moment, specifically was: under the condition that no active human body exists under the lamp, the

ends

33 and 32 of the microprocessor 5 output high level to the 2-path relay module 7, so that the lamp tube 1 and the lamp tube 2 are extinguished; secondly, when a movable human body exists under the lamp, the

ends

33 and 32 of the microprocessor 5 output low levels to the 2-path relay module 7, so that the lamp tube 1 and the lamp tube 2 are completely bright; thirdly, when the movable human body under the lamp is changed into the non-movable human body, the output of the 33 end of the microprocessor 5 is unchanged (the lamp tube 1 is lightened), the 32 end of the microprocessor 5 outputs high level to the 2-way relay module 7, so that the lamp tube 2 is firstly extinguished (prompting the person under the lamp to do slight action), and the time is delayed for 1 minute; if a moving human body is detected within 1 minute of time delay, the 32 end of the microprocessor 5 outputs a low level to the 2-way relay module 7, so that the lamp tube 2 is lightened again; if no active human body is detected under the lamp after 1 minute of delay, the output of the end 33 of the microprocessor 5 is changed into high level and is sent to the 2-way relay module 7, so that the lamp tube 1 is also extinguished, namely the situation is returned to the first condition; if after 1 minute of delay, a moving body is detected under the lamp, then the situation returns to (c).

The subsystem is installed on the lamp holder of every indoor double-tube lighting lamp, and the lamp holder spacing is reasonably distributed according to the sensing range of the human body sensing module 2, so that whether people exist in indoor different positions can be sensed, and through the control of three working modes under different ambient light intensities, the lamps of corresponding positions can be automatically lightened according to the ambient brightness of indoor different positions and whether people exist, so that indoor local lighting control is realized, and energy conservation is achieved.

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

the installation position of the human body induction module 2 is shown in fig. 3, the induction range schematic diagram is shown in fig. 4, the pyroelectric human body infrared sensor module in fig. 4 is installed at a point O, which can be known by a pyroelectric human body infrared sensor module data manual, the induction range is formed by combining a cone and a part of spheres, the diagram is a cross-sectional diagram of the induction range, wherein three points ABC are on the same circle, AO is 3-4 meters BO, L is 5-7 meters, AOB is 100 degrees, the maximum distance induced by the sensor is adjusted to L is 7 meters, AO is 4 meters, the installation height of the pyroelectric human body infrared sensor is 5 meters from the ground, and r is the radius of the human body moving range which can be induced by the sensor on the ground. The coordinates of three points ABC are respectively: a (-4sin50, 0), B (4sin50, 0), C (0, -7+4cos 50), the equation for a circle can be determined from the coordinates of three points ABC, resulting in the following equation: wherein x is the abscissa of the circle center Q, y is the ordinate of the circle center Q, and R is the radius of the circle.

(x+4sin50°)²+y²＝R² (1)

(x-4sin50°)²+y²＝R² (2)

x²+(y+7-4cos50°)²＝R² (3)

The following equations (1), (2) and (3) can be solved: x ═ 0, y ≈ -1.15, R ≈ 3.27, then R can be solved as follows:

(2) the lamp tube on-off detection module 4 is used for detecting the on-off of the lamp tube, and the microprocessor 5 judges the working state of the lamp tube according to the control signal output to the 2-path relay module 7 by the microprocessor 5 and the signal input to the microprocessor 5 by the lamp tube on-off detection module 4. If the output of the microprocessor 5 is at low level (controlling the lamp 1 to light) at end 33 and at high level (detecting the lamp 1 to be in the off state) at end 9, the microprocessor 5 determines that the lamp 1 is in abnormal operation at this time. Secondly, if the output of the end 33 of the microprocessor 5 is low level (controlling the lighting of the lamp 1) and the input of the end 9 is low level (detecting that the lamp 1 is in a lighting state), the microprocessor 5 judges that the lamp 1 works normally at the moment. Thirdly, if the output of the 32 terminal of the microprocessor 5 is at a low level (controlling the lamp 2 to be turned on) and the input of the 10 terminal is at a high level (detecting that the lamp 2 is in an off state), the microprocessor 5 determines that the lamp 2 works abnormally at the moment. If the output of the microprocessor 5 is at low level (controlling the lamp 1 to light up) at the end 32 and the input of the microprocessor 5 is at low level (detecting the lamp 2 to be in a lighting state), the microprocessor 5 determines that the lamp 2 is working normally at this time. By analogy, when the output signals of the 33 and 32 ends of the processor 5 control a certain lamp to be turned off, and the lamp on/off detection module 4 actually detects that the lamp is still on, the lamp works abnormally, otherwise the lamp works normally.

(3) When the lighting/extinguishing state or the working state of the lamp tube is changed normally/abnormally, the microprocessor 5 adds a subsystem ID (each subsystem sets a unique ID to identify different subsystems) to the new state information of the lighting/extinguishing and working state of the lamp tube through the power carrier module i 6 and then sends the new state information to the main system.

2. The working principle of the main system is as follows:

the power carrier module II 9 in the main system receives new state information of normal/abnormal working state and on/off of the lamp tube carrying the subsystem ID, transmitted by the subsystem power carrier module I6 through the 220VAC power inlet wire 12, transmits the information to the computer 11 through the TTL-to-USB module 10, displays the information on the computer 11, and gives an alarm to the main system computer 11 when any lamp tube in the N subsystems works abnormally to prompt a worker to overhaul in time. In addition, the staff can send out the control signal of carrying the subsystem ID of arbitrary fluorescent tube in N subsystems of lighting on/off through the computer 11, this control signal changes USB module 10 to convey to the power carrier module II 9 through TTL, convey to the subsystem power carrier module I6 and send to the microprocessor 5 through 220VAC power inlet wire 12 again, the microprocessor 5 draws subsystem ID from the control signal of the main system and compares with subsystem ID of oneself, if inconsistent do not do any processing, if consistent then according to the control signal output control signal that the main system sends to 2 routes of relay module 7, the lighting on/off of the fluorescent tube 1 or fluorescent tube 2 in the control subsystem.

The working process of the utility model is as follows:

after the system is powered on, the indoor light intensity detection module 3 adopts the photoresistor sensor module to detect the ambient light intensity and converts the ambient light intensity into a voltage analog quantity which is output to the 11 end of the microprocessor 5 from the AO end, and the microprocessor 5 converts the voltage analog quantity into a digital quantity by utilizing a 10-bit A/D converter inside the microprocessor. The microprocessor 5 divides the ambient illumination intensity into three brightness levels according to this digital quantity: when the number is less than 400, the ambient brightness level is super-bright, and the subsystem is in a super-bright working mode; when the number is greater than or equal to 400 and less than 600, the ambient brightness level is brighter, and the subsystem is in a brighter operating mode; when the number is greater than or equal to 600, the ambient light level is darker and the subsystem is in a darker operating mode. Human body induction module 2 utilizes the human infrared sensor module of pyroelectric, can respond to whether there is the human body of activity in the ground radius r scope under the lamp, the human infrared sensor module of pyroelectric sets up to repeatedly trigger the mode, its response delay time sets up to 5 minutes (or longer time), sense 23 ends that 23 ends of human induction module 2's OUT end output high level to microprocessor 5 when having the activity promptly, this high level signal can maintain 5 minutes (or longer time), if the human body of no activity, human induction module 2's OUT end output low level signal to microprocessor 5's 23 ends. The lamp tube on-off detection module 4 is composed of two photoresistance sensor modules. The lamp on/off detection module 4-1 detects the state of the lamp 1, and when the lamp 1 is turned on, the D0 terminal outputs a low level to the 9 terminal of the microprocessor 5, otherwise, outputs a high level to the 9 terminal of the microprocessor 5. The lamp on/off detection module 4-2 detects the status of the lamp 2, and when the lamp 2 is turned on, the D0 terminal outputs a low level to the 10 terminal of the microprocessor 5, otherwise outputs a high level to the 10 terminal of the microprocessor 5.

When the ambient brightness level is super bright, the subsystem is in a super bright mode of operation. The microprocessor 5 does not process the signal of the 23 end of the microprocessor 5 input by the human body sensing module 2. Meanwhile, the

terminals

33 and 32 of the microprocessor 5 output high levels to the terminals IN1 and IN2 of the 2-way relay module 7, so that the normally closed contacts at the terminals NC1 and NC2 IN the 2-way relay module 7 are disconnected, the power supply circuit for the lamp 1 and the lamp 2 is disconnected, and the lamp 1 and the lamp 2 are both extinguished.

When the ambient light level is brighter, the subsystem is in a brighter mode of operation. The 32 end of the microprocessor 5 outputs high level to the IN2 end of the 2-way relay module 7, so that the normally closed contact end of the NC2 end IN the 2-way relay module 7 is disconnected, the power supply loop of the lamp tube 2 is disconnected, and the lamp tube 2 is extinguished. Meanwhile, the microprocessor 5 detects a signal inputted from the OUT terminal of the human body induction module 2 at the 23 terminal thereof. If the microprocessor 5 detects that the input of the 23 end is low level (no active person is under the lamp), the 33 end of the microprocessor 5 outputs high level to the IN1 end of the 2-way relay module 7, so that the NC1 end normally-closed contact IN the 2-way relay module 7 is disconnected, the power supply circuit of the lamp tube 1 is disconnected, and the lamp tube 1 is extinguished. If the microprocessor 5 detects that the input of the 23 end is high level (when a person moves under the lamp), the 33 end of the microprocessor 5 outputs low level to the IN1 end of the 2-path relay module 7, so that a normally closed contact at the NC1 end IN the 2-path relay module 7 is closed, a power supply loop of the lamp tube 1 is switched on, and the lamp tube 1 is lightened.

When the ambient light level is dark, the subsystem is in a dark operating mode. At this time, the microprocessor 5 detects a signal inputted from the OUT terminal of the human body sensing module 2 at the terminal 23 thereof. The following conditions are: if the microprocessor 5 detects that the input at the end 23 is low level (when no active person is under the lamp), the ends 33 and 32 of the microprocessor 5 output high level to the ends IN1 and IN2 of the 2-way relay module 7, so that the normally closed contacts at the ends NC1 and NC2 IN the 2-way relay module 7 are 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. Case two: if the microprocessor 5 detects that the input at the end 23 is high level (when a person moves under the lamp), the ends 33 and 32 of the microprocessor 5 output low level to the ends IN1 and IN2 of the 2-way relay module 7, so that the normally closed contacts at the ends NC1 and NC2 inside the 2-way relay module 7 are closed, the power supply circuit of the lamp 1 and the lamp 2 is switched on, and the lamp 1 and the lamp 2 are lighted. Case (c): if the microprocessor 5 detects a jump of the input at the 23 end from high level to low level (when an active person becomes an inactive person under the lamp), the output at the 33 end of the microprocessor 5 is unchanged (the lamp tube 1 is lighted), the 32 end of the microprocessor 5 outputs high level to the IN2 end of the 2-way relay module 7, so that the normally closed contact at the NC2 end of the 2-way relay module 7 is disconnected, the power supply circuit of the lamp tube 2 is disconnected, and the lamp tube 2 is firstly extinguished to prompt the person under the lamp to do slight action. Meanwhile, the microprocessor 5 delays for 1 minute; if the microprocessor 5 detects a jump from low level to high level input at the 23 end (no active person becomes an active person under the lamp) within the 1 minute delay, the 32 port of the microprocessor 5 outputs low level to the IN2 end of the 2-way relay module 7, so that the normally closed contact at the NC2 end of the 2-way relay module 7 is closed, the power supply circuit of the lamp tube 2 is switched on, and the lamp tube 2 is lighted again. After 1 minute of time delay, if the microprocessor 5 detects that the input of the 23 end is low level (when no active person exists under the lamp), the 32 end of the microprocessor 5 outputs high level to the IN1 end of the 2-way relay module 7, so that the normally closed contact of the NC1 end of the 2-way relay module 7 is disconnected, the power supply circuit of the lamp tube 1 is disconnected, the lamp tube 1 is also extinguished, namely the situation returns to the first condition; if the microprocessor 5 detects that the input at terminal 23 is high (there is a moving person under the light), it returns to condition two.

In the working process of the system, the lamp tube on-off detection module 4 continuously detects the on/off states of the lamp tube 1 and the lamp tube 2 and respectively outputs signals from the D0 terminals of the lamp tube on-off detection module 4-1 and the lamp tube on-off detection module 4-2 to the 9 and 10 terminals of the microprocessor 5. The microprocessor 5 judges whether the lamp tube works normally or abnormally according to output signals of

terminals

33 and 32 and input signals of

terminals

9 and 10 during the work: if the output of the microprocessor 5 is at low level (controlling the lamp 1 to light) at end 33 and at high level (detecting the lamp 1 to be in the off state) at end 9, the microprocessor 5 determines that the lamp 1 is in abnormal operation at this time. Secondly, if the output of the end 33 of the microprocessor 5 is low level (controlling the lighting of the lamp 1) and the input of the end 9 is low level (detecting that the lamp 1 is in a lighting state), the microprocessor 5 judges that the lamp 1 works normally at the moment. Thirdly, if the output of the 32 terminal of the microprocessor 5 is at a low level (controlling the lamp 2 to be turned on) and the input of the 10 terminal is at a high level (detecting that the lamp 2 is in an off state), the microprocessor 5 determines that the lamp 2 works abnormally at the moment. If the output of the microprocessor 5 is at low level (controlling the lamp 2 to be lighted) at the end 32 and the input of the microprocessor 5 is at low level (detecting that the lamp 2 is in a lighted state), the microprocessor 5 determines that the lamp 2 is working normally at this time. By analogy, when the output signals of the 33 and 32 ends of the processor 5 control a certain lamp to be turned off, and the lamp on/off detection module 4 actually detects that the lamp is still on, the lamp works abnormally, otherwise the lamp works normally.

In the working process of the system, when the microprocessor 5 detects that input signals (the lighting/extinguishing state of the lamp tube) at the 9 terminal and the 10 terminal are changed or when the normal/abnormal working state of the lamp tube obtained by the microprocessor 5 is judged to be changed, the microprocessor 5 adds the current new lamp tube state information (the lighting/extinguishing state information of the lamp tube and the normal/abnormal working state information of the lamp tube) to a subsystem ID through a 22(TXD) terminal (each subsystem sets a unique ID for identifying different subsystems) and sends the new lamp tube state information to an RX terminal of the power carrier module I6, the power carrier module I6 sends the new lamp tube state information carrying the subsystem ID to a power carrier module II 9 of a main system through a 220VAC power line 12, the TX terminal of the power carrier module II 9 sends the received new lamp tube state information carrying the subsystem ID to an RXD terminal of a TTL-to-USB module 10, the TTL-to-USB module converts a TTL level signal received by an RXD end of the TTL-to-USB module, sends new state information of the lamp tubes carrying the subsystem IDs to the computer 11 through a USB port of the computer 11, updates and displays the lighting/extinguishing state or the normal/abnormal working state of each lamp tube in the corresponding subsystem on the computer 11, and sends alarm information to prompt a manager to overhaul the lamp tubes in time if any lamp tube in the N subsystems works in the abnormal state.

In the working process of the system, when a manager needs to remotely and manually control the on/off of any lamp tube in the N subsystems, the manager can send out a control signal of any lamp tube in the on/off subsystem carrying the subsystem ID through the computer 11, for example: when a manager needs to light on/off the lamp tube 1 in a certain subsystem, a control signal carrying an ID of the certain subsystem for lighting/off the lamp tube 1 can be sent out through the computer 11, the control signal is sent out through a USB port of the computer 11, and is converted into a TTL level signal through the TTL-to-USB module 10, the TTL-to-USB control signal is transmitted to an RX end of the power carrier module II 9 from a TXD end of the TTL-to-USB module 10, the power carrier module II 9 sends the control signal carrying the ID of the certain subsystem to the subsystem power carrier module I6 through the 220VAC power inlet wire 12, and the TX end of the power carrier module I6 sends the received control signal carrying the ID of the certain subsystem from the main system to a 21(RXD) end of the microprocessor 5. After receiving the control signal (lighting/extinguishing the lamp 1) carrying a certain subsystem ID, the microprocessor 5 extracts the subsystem ID IN the control signal and compares the subsystem ID with the subsystem ID of the microprocessor, if the subsystem ID is not consistent, no processing is performed, if the subsystem ID is consistent, the microprocessor outputs a signal (low level/high level) from the 33 end of the control signal to the IN1 end of the 2-way relay module 7 according to the control signal, so that the normally closed contact at the NC1 end IN the 2-way relay module 7 is closed/opened, and the power supply circuit of the lamp 1 is switched on/off, so that the lamp 1 is lit/extinguished. By analogy, the manager can also remotely and manually control the lighting/extinguishing of the lamp tube 2 in a certain subsystem in the main system, or manually control the lighting/extinguishing of the lamp tube 1 and the lamp tube 2 in a certain subsystem at the same time. In this way, the computer 11 in the main system can manually control the on/off of any lamp in the N sub-systems.
