FIG. 4 is a structural block chart of the present invention. The local power is input by the AC / DC power converter in block 2.1, and the part of the DC power output by it goes to the block 2.7 LED lamp control and power consumption measurement interface to drive the LED lamp directly. Another part can go to the power adapter and control circuit in block 2.2 and output several different voltages to provide to the present invention. For example, the battery charging voltage includes a stable 5V operating voltage, 24V relay voltage and 9V driving voltage.

Block 2.3 battery charge / discharge control and protection circuit can provide several battery charge upper limit voltage settings and several battery discharge lower limit voltage settings. Thereby, the battery can hold | maintain the state which is not an overcharge at full charge at any time. When a power failure occurs, this block immediately detects and directly controls to skip to the night lamp group situation mode, relays the relay, and turns on the external battery power. This replaces the output of the block 2.1 AC / DC power converter, and simultaneously activates the battery discharge lower limit voltage comparison circuit. When the battery is discharged and falls below the lower limit set voltage, the battery power is turned off.

In block 2.4 night lamp connection power saving control interface, this interface can be directly controlled by the existing wall switch to switch to night lamp group situation mode. In addition, through connection, after receiving the interlock control of one wall switch at the main control end, and starting the night lamp power saving function, block 2.6 microprocessor interface and peripheral equipment, at the same time, other Turn off most of the lighting fixtures. In this way, the lighting of only a small number of lighting fixtures set as night lamps is suspended, and the necessary passage lighting is maintained.

Block 2.5 In the human body sensor PIR control interface block, the output power of the human body sensor PIR is obtained through an optical isolation circuit to obtain a control signal. Then provide block 2.6 microprocessor and peripheral equipment. Subsequently, based on the pre-set contents of the group situation setting stored by the microprocessor, the LED lamp to be controlled by the approach or separation of the human body measured by the human body sensor PIR is controlled.

Block 2.6 Microprocessors and peripherals contain programs, memory, etc. As a result, various group situation input signals such as blocks 2.4, 2.5, 2.9, and 2.10 can be read at any time. In addition, block 2.7 LED lamp control and power consumption measurement interface are controlled based on the stored contents of group situation settings stored by the microprocessor, each LED lamp is turned on or off, and the power consumption of each LED lamp is measured. . The result is the transmission of data into the remote server through the 2.11 RS-485 communication interface.

Block 2.7 The LED lamp control and power consumption measurement interface block consists of 8 power MOS FETs (Metal Oxide Semiconductor Field Effect Transistors), a drive circuit composed of one metal oxide semiconductor field effect transistor, a set of voltage measurement circuits, It is composed of a set of current measurement conversion circuits, a set of status reading interfaces and the like.

Block 2.6 Microprocessors and peripheral equipment control each POWER MOS through the serial conversion parallel IC. In this way, ON / OFF of each LED lamp is controlled. Separately, the current LED drive voltage and the combined drive current are attenuated and expanded by an appropriate ratio, and the current voltage (V) and current (A) values are measured by the A / D interface of the microprocessor in block 2.6. And convert. Through program calculation, watt (W) and power consumption (Wh) values are calculated. Finally, the status of each LED lamp is read by a parallel conversion series IC, the source of these combined currents is confirmed, and accurately distinguished and recorded.

Block 2.8 External control setting interface block is designed to correspond to the external setting control box attached to Block 2.12. When the power converter is in a normal state (block 2.1) and cannot be used due to a failure, the power switch of block 2.12 can be used. At this time, the serial conversion parallel control LED lamp IC in block 2.6 is deactivated, that is, the permission to turn on and off the control LED is executed instead of the external setting control box. This block provides a power supply for the external block 2.12, which allows each switch to be moved manually and controls each LED lamp on and off one by one to achieve the purpose of emergency use. At the same time, the contents of the group combination form are set from the outside through this interface.

Block 2.9 Block of optical isolation carrier communication interface corresponds to the intelligent operation and control device attached to Block 2.13. The device uses the wiring and position of existing wall light switches. The interface circuit of this block uses the existing wiring of the two-wire switch, and approaches the maximum value during the period of the positive half cycle. Place control signals directly on it with the attached intelligent operation and control device in block 2.13. This block 2.9 obtains information conveyed by the carrier by isolating light passing through in a timely manner. Program decoding can be performed according to block 2.6 to know the instruction to control the attached intelligent operation and control device. In this way, the purpose of controlling the ON / OFF of the LED lamp and intelligently operating and controlling the lamp using the existing switch wiring is achieved.

Block 2.10 The wall switch group control interface block receives the ON / OFF information of the existing wall switch and detects the ON / OFF state of the original wall switch through light isolation. In other words, the presence or absence of the power supply is converted into a logic HI-LOW signal. Subsequently, the detected signal is read by block 2.6, and the ON / OFF of the LED lamp is controlled. In this way, another type of control method is provided that uses the existing wiring and switches, and allows the user to make the necessary group situations through the settings even when no change is required.

Block 2.11 The main function of the block of the RS-485 communication interface is to convert the serial connection communication signal (UART) of the block 2.6 microprocessor to RS-485 signal, which is in a differential manner, remote end server To achieve remote query and control objectives.

The control box of the external setting control box attached to block 2.12 uses a single 15-core cable and is connected to block 2.8. As a result, a direct connection can be made, the power switch on the control box can be moved, and an LED lamp ON / OFF control right can be obtained. By receiving the setting and controlling the switches on the control box one-on-one, if only a part of the controller fails, the lighting mechanism can be controlled. At the same time, this setting of the control box can provide an external setting for the group combination form content and is stored in the memory of the block 2.6 microprocessor.

The intelligent operation and control device block attached to block 2.13 is implemented using the existing wiring and position of the wall switch. The external appearance of this block is designed as a control box of the same size as a single wall switch. The power supply that requires it is obtained from the two wires of the original wall switch. At the same time, using the carrier signal near the electrical angle close to 90 degrees of the sine wave's positive half circumference, the signal of the lighting fixture to be controlled is placed on it, received by block 2.8, decoded by block 2.6, LED lamp Enforce the purpose of control. In this way, intelligent control of the LED lamp is realized without using the wiring method.

Below, the principle of operation of this invention and its effect | action are demonstrated.
5 and 6 are circuit diagrams of the main body controller, FIG. 7 is a circuit diagram of the attached intelligent operation and control device, and FIG. 8 is a circuit diagram of the attached external setting control box.

The 2.1 AC / DC power supply in FIG. 5 receives local power from J15 and connects to the J16 input terminal of the AC / DC power converter via fuse F1 and temperature protection switch SW3. The DC power source that it outputs is provided as the power source required by the entire controller, and both ends of AC-L and AC-N in the figure are connected to block 2.3 and used for power outage inspection.

In the 2.2 power adapter and control circuit of FIG. 5, the power source is input from DC-IN, connected to the capacitor C1, and can be selected in three stages via the switch SW1. As shown in the figure, 1-2 conduction is a normal feeding position, the power is input from diode D1, and then redistributed to different power needs. 2-3 continuity is that when the controller fails, the power is supplied from the resistors R11 and R14, the voltage is stabilized by the voltage stabilization diode ZD3, and each POWER MOS is directly controlled through the diodes D11 to D18. Light. Another stage of SW1 is in the middle, which is power off.

During normal power supply, if the power supply is input from the diode D1, the voltage stabilization and the resistor RT1 and the transistor Q1 can obtain a stable 24V voltage through the resistor R12 and the voltage stabilizing diode ZD2, and further, the resistor R8, A 9V power supply can be obtained through the voltage stabilizing diode ZD1. Separately, the power supply reaches the U2 voltage stabilization IC (integrated circuit) via the resistor RT2 and can obtain a stable voltage of 5V through an appropriate ratio of R17 and R18 resistors, which is provided to peripheral equipment such as a microprocessor. For use. Separately, the 9V portion is divided into resistors such as R28, R29, R30, R31, and R32 to obtain four divided voltage values such as 6V, 4.5V, 3.75V, and 3V. Via J11, one of the voltages is selected and output as Vref (reference voltage). The voltage is for 2.3 battery charge and discharge upper and lower judgment voltage. The battery voltages it corresponds to are 48V, 36V, 30V and 24V.

Separately, an input power source is also provided as a power source for the LED lamp via the relay RY1, and the relay RY1 is also controlled by the transistor Q10. When Q10 is ON, the input power supply goes through resistors R15, RT3 and diode D19, and becomes the LED power supply, limiting the power supply. In this way, only a small amount of electric power is provided to the LED lamp, and the purpose of making the LED lamp for illumination a night lamp is achieved.

When the relay RY1 is ON, that is, in the night lamp mode, the power supply reaches the switch SW2 via the diode D22. If SW2 is in the ON state, that is, in the state of 2-3 and 4-5 conduction in the figure, the power supply passes through the connection to the next controller of SO-1 and SO-2, and 2.4 night lamp connection power saving control Passing through the interface, the next lighting fixture can be linked and controlled to night lamp mode. Therefore, it is possible to make this controller the main night lamp switch simply by turning on SW2, and all connected controllers can be activated by connection and all can be linked together to control to night lamp mode. it can.

In FIG. 5, 2.3 battery charge, discharge control and protection, DC-IN is provided for charging an external battery. Since the battery selection and DC-IN are the same voltage, it is necessary to go through the booster circuit of the integrated circuit (IC) U7. Among them, J14 selects how much voltage of DC-IN is increased to be the upper limit voltage of charging. ZD4 to ZD6 in the figure are voltage stabilizing diodes having different voltage values. For example, the battery is 24V etc., ie, J14 1-2 pin short. At this time, the output voltage of the integrated circuit (IC) U7 is 30V, 36V or 48V obtained by adding the voltage of ZD4 to the voltage of the upper limit voltage DC-IN on the capacitor C23. The charging voltage is obtained by adding ZD5, ZD6, or ZD7 to DC-IN, respectively. Connect an external battery on the J17 connector. The above charging voltage charges the battery via the diode D35, the resistor RT12, and the transistor Q12. The combination of voltage stabilizing diode ZD10 and resistor R48 limits the maximum charging current. Its highest charging voltage is limited by the integrated circuit (IC) U7 and the selected ZENER (ZD4-ZD7).

The integrated circuit U11 optical isolation IC checks for power outages. When the AC-L and AC-N power supplies are lost, no current flows through the light emitting diode D42. In the C pole of the integrated circuit U11, the positive end of PIN 10 of U10A changes to HI, which causes U10A to output HI, the transistor Q13 to conduct, and the relay RY2 to operate. Battery power is provided to DC-IN via relay RY2. That is, the entire controller power supply is powered by an external battery. At the same time, the power failure signal is forced to enter the night lamp mode via the diode D51, the relay RY1 is operated, and the limited power is provided to the LED lamp for use. As a result, the external battery can light up the controller's LED lamp directly with less power and extend the usage time.

If the battery is continuously used, the voltage gradually decreases. When the battery voltage is discharged until the divided voltage of R55 and R57 becomes smaller than the selected Vref voltage, U12A outputs LOW. This passes through diode D41 and changes the PIN 7 positive end of U10A to LOW, which turns off transistor Q13. Thus, the relay RY2 becomes OPEN, the battery power supply is stopped, and the battery is protected from being excessively discharged.

The 2.4 night lamp connection power-saving control interface in Fig. 5 is the U17 optical isolation IC in the figure, which inspects the power supply of the existing wall switch. A general wall switch uses a two-wire switch to control a lighting fixture power source. Therefore, this interface detects the power source that lights the original lighting device. AC-L4 and AC-N4 in the figure are used for signal control. When the wall switch is ON, a current is passed through the light emitting diode D47, so that U17 outputs and U1DPIN 12 and 13 pins are LOW. On the other hand, when the wall switch is OFF, HI is output, and then the NLC is connected to the U16 microprocessor via the U1D output pin (see FIG. 6). Thereby, the command of whether to switch to a night lamp can be obtained by turning on or off the existing wall surface switch. The point is that it can be directly specified and used without the need for separate wiring and switches.

U19 provides an interface that can control the night lamp. If this controller wants to control the connection, set switch SW5 to ON. As a result, when there is a power input between SO1-1 and SO1-3, the U1D-PIN pins 12 and 13 are set to LOW and NLC is set to HI as controlled by AC-L3 and AC-N3. And can tell U16 to enter night lamp mode. Through the design of this interface, a single wall switch can control the lighting of a large area such as an entire building or a floor, and at the same time can be turned into a night lamp. In this way, the illumination power source that has kept the minute power and forgot to turn it off is turned off.

The 2.5 human body sensor PIR control interface shown in FIG. 5 similarly uses a light isolation IC U14 to switch the power supply to the control signal system. Thereby, the power supply of the existing wall switch can be provided to the human body sensor PIR. When the sensor detects that there is a person, it outputs a power source and turns on the light. Here, when the human body sensor PIR detects that there is a person, a current flows through the light emitting diode D45 in the figure, the C pole of the U14 light isolation IC sets U1C-PIN 8, PIN 9 to LOW, and U1C Output signal to HI and notify U16 microprocessor. In this way, the human body sensor PIR mode is activated, and when the presence of a person is detected, the lighting device group to be lit is turned on.

In the 2.6 microprocessor and peripheral equipment of FIG. 6, the program operation and control of the present invention must first be identified and processed by a wall switch on the U16 microprocessor. As a result, the four types of control signals, the night lamp control signal (NLC), the human body sensor (PIR) inspection control signal, the situation group control signal (GPC), and the intelligent operation and control signal (PRXD) that come from the power adapter are lit. Try to enforce the orders. The content of the lighting is based on the content set in the memory of U16. It reads the contents of G1 to G8 and MD1 to MD4 via U15 and U18 parallel conversion series ICs by U16 by setting the internal dip switch or the external setting control box, and stores them in the internal memory.

Separately, the two measurement signals are passed, and the voltage signal (AD1) and current signal (AD2) are the voltage (V) that drives the LED lamp at that time by the U16 internal linear conversion digital (A / D) circuit. You can know the numerical value of the current (A) that drives the LED lamp. Subsequently, a synergistic calculation is performed by an internal program, and further accumulation is performed to obtain watts (W) and power consumption (Wh). At the same time, it can be obtained via U15 parallel conversion series IC. Only when these LED lamps are gathered, it is possible to identify and record whether there is any abnormality, and to achieve the function of main failure reporting. Separately, the U16 microprocessor passes the U4 serial conversion parallel IC, and sends the signal of the lighting fixture to be lit to each control MOS from the diodes D23 to D30 (Q2 to Q9 in the figure). Finally, the U16 microprocessor can read the controller communication ID via U18, so that the SW4 (RS-485 address) settings are connected by the U9 RS-485 communication interface IC and the remote end server. Control and data storage are performed.

In the 2.7 LED lamp control and power consumption measurement interface shown in Fig. 6, there are a total of 8 POWER MOS drive circuits in the figure, which are composed of field effect transistors Q2 to Q9, and each set consists of one external LED lamp. (LED-OUT1 to OUT8 in the figure)

The first set will be described as an example. When G1 input is at HI potential, Q2 conducts. Conversely, if the input is LOW, Q2 will OPEN. If Q2 becomes conductive, the D6 indicator will light and the LED lamps connected to LED-COM and LED-OUT1 will light. RT4 is a protection resistor that overheats RT4 when overloaded, and the resistor has a large thermal change to limit and protect the current. Each other set of operating principles is also homologous.

In the figure, R2 and R13 are divided and connected to AD1, and the LED drive voltage is measured. The drive current of each set of LEDs gathers and flows to R36. U3A expands the voltage on the top surface of R36, and the output voltage of U3A is the AD2 voltage, which is directly proportional to the combined current of 1-8 sets of LEDs. Thus, with the U16 microprocessor, the internal A / D converter can measure AD1 and AD2, and know the LED lamp drive voltage (V), current (A), watt (W) and power consumption (Wh).

The 2.8 external control setting interface of FIG. 5 mainly provides one 15 PIN connector. PIN 1 to PIN 8 of the connector are connected corresponding to G1 to G8 of 2.7 and control whether to conduct to Q2 to Q9. In this way, eight external LED lamp sets of LED-OUT1 to OUT8 are controlled. The necessary power supply is obtained by stepping down from the 24V power supply with R85, and the control right is acquired by pin 13 of J3. PIN 13 in the figure is pulled to the B pole of Q11. Normally, the B pole of Q11 is at HI potential, which causes the C pole of Q11 to go LOW. At this time, the output of U4 is controlled by the U16 microprocessor IC.

After starting to use the external setting control box, PIN 13 of this interface changes to LOW. As a result, the U4 output expires, and the LED lamp control right is controlled by the interfaces J13-1 to J13-1. Its purpose is to provide another kind of circuit structure in the event of a circuit failure and to provide a simple emergency lighting control scheme.

Separately, this setting control box provides four sets of situation group settings. It includes two sets of group control lighting settings, one set of anthropometric lighting settings, and one set of night lamp control lighting settings. These set values are read by U16 microprocessor IC through U15, U18 parallel variable series connection IC, and G1 to G8 and MD1 to MD4 are read. The contents at that time are stored in the memory inside the U16, and when these control commands are received, it becomes the basis for lighting the LED lamp.

The 2.9 optical isolation carrier communication control interface in FIG. 6 detects the carrier signal during the positive half cycle by the optical isolation IC U8. After the original wall switch is replaced with a single intelligent operation and control device, the device modulates to a single byte serial connection communication (UART) signal near the highest half-round maximum. The signal modulated instantaneously changes the UART from HI to LOW communication signal instantaneously. It quickly changes to the ON or OFF signal at the maximum value of the positive half circle. This signal is faithfully represented on R53, passed through U1B, converted to a PRXD signal, and then the content of the carrier signal is identified by the U16 microprocessor to achieve the purpose of intelligent control.

The 2.10 wall switch group control interface in Fig. 6 uses the optical isolation IC U5 as the AC-L2 and AC-N2 power supply, converts it to the control signal system, and directly uses the existing wall lighting switch wiring and switches. Connect the power supply originally provided to the lighting fixture to AC-L2 and AC-N2 in the figure. When the switch is ON, current flows to the light emitting diode D37, U1-PIN 1 and PIN 2 on the C pole of U5 become LOW, U1A output GPC becomes HI, notifies the U16 microprocessor, and the situation group control mode is set. to start.

The 2.11 RS-485 communication interface in FIG. 6 mainly converts U16 serial connection communication signals, SRXD and STXD, into RS-485 differential signals by a U9 RS-485 conversion IC. As a result, the RS-485-A and RS-485-B signals are remotely transmitted to a system control center such as a server or a PC. This allows the system to remotely collect power information and luminaire controls for each LED lamp.

The attached intelligent operating device of FIG. 7 utilizes the existing wall lighting switch wiring and position. Its external shape is similar to the existing switch box. The power acquisition and communication interface are both the existing two wires on the wall switch. The BD1 bridge rectifier in the figure acquires power from the existing two-wire electric wire of the wall surface switch, and supplies it to the device via D105 and C105 for use. U107 is a power adapter IC that supports the resistance value design of peripheral equipment R106 and R109, and obtains the 5V power supply necessary for this device from the local power.

Separately, the U105 optical isolation IC can pass through D102, R102, and ZD101 and detect the positive and negative half cycles of the local power. The detected local power positive and negative half-circumferential signals are directly input to the U104 microprocessor via U101-PIN 3 and are used as synchronization signals for signals to be transmitted.

In other words, U104 is U101-PIN
Based on the signal time base of 3, calculate the electric angle time base of the highest value of the city power half-round. Furthermore, the signal to be transmitted is passed through the U101 in a timely manner, the Q109 POWER MOS is driven, the digital signal is temporarily turned on or off, placed on the power line, and the maximum value of the positive half-circumference is around 90 degrees electrical angle. Using a power line, the digital signal to be transmitted is converted into a pulse signal of a two-wire electric wire presence / absence current.

The magnitude of this pulse current is controlled by R8, and this pulse current is detected by the 2.9 optical isolation carrier communication control interface. In addition, it is reduced to a digital signal, received and identified by the U16 microprocessor, and the communication content is enforced to achieve the purpose of intelligent control of the lamp.

Separately, SW101 to SW108 in the figure are individual control operation interfaces of eight LED lamps to be controlled correspondingly. SW109 to SW112 are situation group collective control operation interfaces. D108 to D120 are indicators corresponding to each other, and are controlled by the U104 microprocessor through serial conversion parallel ICs U108 and U109. As a result, the entire lighting control system is made intelligent, and no new piping or wiring is required.

In the attached external setting control box of FIG. 8, J24 in the figure is connected to J3 of the 2.8 external control setting interface. When SW8 is set to ON, the setting and control functions of this external setting control box are activated. At this time, PIN 13 is LOW, which causes the internal LED lamp control IC U4 to expire. The LED lamp control permission is controlled by this control box. At this time, the on / off of the LED lamps 1 to 8 can be directly controlled by moving the switches corresponding to SW1 to SW8. At the same time, in a certain lighting combination arrangement, if MD1-MD4 press the corresponding switch, the internal microprocessor (U16) memorizes the group type set at that time, and U16 receives the command Sometimes it is the basis for controlling the lighting.

FIG. 4 is a structural block chart of the present invention. The local power is input by the AC / DC power converter in block 2.1, and the part of the DC power output by it goes to the block 2.7 LED lamp control and power consumption measurement interface to drive the LED lamp directly. Another part can go to the power adapter and control circuit in block 2.2 and output several different voltages to provide to the present invention. For example, the battery charging voltage includes a stable 5V operating voltage, 24V relay voltage and 9V driving voltage.

Block 2.3 battery charge / discharge control and protection circuit can provide several battery charge upper limit voltage settings and several battery discharge lower limit voltage settings. Thereby, the battery can hold | maintain the state which is not an overcharge at full charge at any time. When a power failure occurs, this block will immediately detect and directly control to skip to the night lamp group situation mode, relay the control relay, and turn on the external battery power. This replaces the output of the block 2.1 AC / DC power converter, and simultaneously activates the battery discharge lower limit voltage comparison circuit. When the battery is discharged and falls below the lower limit set voltage, the battery power is turned off.

In block 2.4 night lamp connection power saving control interface, this interface can be directly controlled by the existing wall switch to switch to night lamp group situation mode. In addition, through connection, after receiving the interlock control of one wall switch at the main control end, and starting the night lamp power saving function, block 2.6 microprocessor interface and peripheral equipment, at the same time, other Turn off most of the lighting fixtures. In this way, the lighting of only a small number of lighting fixtures set as night lamps is suspended, and the necessary passage lighting is maintained.

Block 2.5 In the human body sensor PIR control interface block, the output power of the human body sensor PIR is obtained through an optical isolation circuit to obtain a control signal. Then provide block 2.6 microprocessor and peripheral equipment. Subsequently, based on the pre-set contents of the group situation setting stored by the microprocessor, the LED lamp to be controlled by the approach or separation of the human body measured by the human body sensor PIR is controlled.

Block 2.6 Microprocessors and peripherals contain programs, memory, etc. As a result, various group situation input signals such as blocks 2.4, 2.5, 2.9, and 2.10 can be read at any time. In addition, block 2.7 LED lamp control and power consumption measurement interface are controlled based on the stored contents of group situation settings stored by the microprocessor, each LED lamp is turned on or off, and the power consumption of each LED lamp is measured. . The result is the transmission of data into the remote server through the 2.11 RS-485 communication interface.

Block 2.7 The LED lamp control and power consumption measurement interface block consists of 8 POWER
Composed of a drive circuit composed of MOS FET (Metal Oxide Semiconductor Field Effect Transistor), 1 set of voltage measurement circuit, 1 set of current measurement conversion circuit, 1 set of state reading interface, etc. .

Block 2.6 Microprocessors and peripheral equipment control each POWER MOS through the serial conversion parallel IC. In this way, ON / OFF of each LED lamp is controlled. Separately, the current LED drive voltage and the combined drive current are attenuated and expanded by an appropriate ratio, and the current voltage (V) and current (A) values are measured by the A / D interface of the microprocessor in block 2.6. And convert. Through program calculation, watt (W) and power consumption (Wh) values are calculated. Finally, the status of each LED lamp is read by a parallel conversion series IC, the source of these combined currents is confirmed, and accurately distinguished and recorded.

Block 2.8 External control setting interface block is designed to correspond to the external setting control box attached to Block 2.12. When the power converter is in a normal state (block 2.1) and cannot be used due to a failure, the power switch of block 2.12 can be used. At this time, the serial conversion parallel control LED lamp IC in block 2.6 is deactivated, that is, the permission to turn on and off the control LED is executed instead of the external setting control box. This block provides a power supply for the external block 2.12, which allows each switch to be moved manually and controls each LED lamp on and off one by one to achieve the purpose of emergency use. At the same time, the contents of the group combination form are set from the outside through this interface.

Block 2.9 Block of optical isolation carrier communication interface corresponds to the intelligent operation and control device attached to Block 2.13. The device uses the wiring and position of existing wall light switches. The interface circuit of this block uses the existing wiring of the two-wire switch, and approaches the maximum value during the period of the positive half cycle. Place control signals directly on it with the attached intelligent operation and control device in block 2.13. This block 2.9 obtains information conveyed by the carrier by isolating light passing through in a timely manner. Program decoding can be performed according to block 2.6 to know the instruction to control the attached intelligent operation and control device. In this way, the purpose of controlling the ON / OFF of the LED lamp and intelligently operating and controlling the lamp using the existing switch wiring is achieved.

Block 2.10 The wall switch group control interface block receives the ON / OFF information of the existing wall switch and detects the ON / OFF state of the original wall switch through light isolation. In other words, the presence or absence of the power supply is converted into a logic HI-LOW signal. Subsequently, the detected signal is read by block 2.6, and the ON / OFF of the LED lamp is controlled. In this way, another type of control method is provided that uses the existing wiring and switches, and allows the user to make the necessary group situations through the settings even when no change is required.

Block 2.11 The main function of the block of the RS-485 communication interface is to convert the serial connection communication signal (UART) of the block 2.6 microprocessor to RS-485 signal, which is in a differential manner, remote end server To achieve remote query and control objectives.

The control box of the external setting control box attached to block 2.12 uses a single 15-core cable and is connected to block 2.8. As a result, a direct connection can be made, the power switch on the control box can be moved, and an LED lamp ON / OFF control right can be obtained. By receiving the settings and controlling the switches on the control box one-on-one, if only a part of the controller fails, the lighting mechanism can be controlled. At the same time, this setting of the control box can provide an external setting for the group combination form content and is stored in the memory of the block 2.6 microprocessor.

The intelligent operation and control device block attached to block 2.13 is implemented using the existing wiring and position of the wall switch. The external appearance of this block is designed as a control box of the same size as a single wall switch. The power supply that requires it is obtained from the two wires of the original wall switch. At the same time, using the carrier signal near the electrical angle close to 90 degrees of the sine wave's positive half circumference, the signal of the lighting fixture to be controlled is placed on it, received by block 2.8, decoded by block 2.6, LED lamp Enforce the purpose of control. In this way, intelligent control of the LED lamp is realized without using the wiring method.

Below, the principle of operation of this invention and its effect | action are demonstrated.
5 and 6 are circuit diagrams of the main body controller, FIG. 7 is a circuit diagram of the attached intelligent operation and control device, and FIG. 8 is a circuit diagram of the attached external setting control box.

The 2.1 AC / DC power supply in FIG. 5 receives local power from J15 and connects to the J16 input terminal of the AC / DC power converter via fuse F1 and temperature protection switch SW3. The DC power source that it outputs is provided as the power source required by the entire controller, and both ends of AC-L and AC-N in the figure are connected to block 2.3 and used for power outage inspection.

In the 2.2 power adapter and control circuit of FIG. 5, the power source is input from DC-IN, connected to the capacitor C1, and can be selected in three stages via the switch SW1. As shown in the figure, 1-2 conduction is a normal feeding position, the power is input from diode D1, and then redistributed to different power needs. 2-3 continuity is that when the controller fails, the power is supplied from the resistors R11 and R14, the voltage is stabilized by the voltage stabilization diode ZD3, and each power is supplied through the diodes D11 to D18.
Control MOS directly and turn on one lamp each. Another stage of SW1 is in the middle, which is power off.

During normal power supply, if the power supply is input from the diode D1, the voltage stabilization and the resistor RT1 and the transistor Q1 can obtain a stable 24V voltage through the resistor R12 and the voltage stabilizing diode ZD2, and further, the resistor R8, A 9V power supply can be obtained through the voltage stabilizing diode ZD1. Separately, the power supply reaches the U2 voltage stabilization IC (integrated circuit) via the resistor RT2 and can obtain a stable voltage of 5V through an appropriate ratio of R17 and R18 resistors, which is provided to peripheral equipment such as a microprocessor. For use. Separately, the 9V portion is divided into resistors such as R28, R29, R30, R31, and R32 to obtain four divided voltage values such as 6V, 4.5V, 3.75V, and 3V. Via J11, one of the voltages is selected and output as Vref (reference voltage). The voltage is for 2.3 battery charge and discharge upper and lower judgment voltage. The battery voltages it corresponds to are 48V, 36V, 30V and 24V.

Separately, an input power source is also provided as a power source for the LED lamp via the relay RY1, and the relay RY1 is also controlled by the transistor Q10. When Q10 is ON, the input power supply goes through resistors R15, RT3 and diode D19, and becomes the LED power supply, limiting the power supply. In this way, only a small amount of electric power is provided to the LED lamp, and the purpose of making the LED lamp for illumination a night lamp is achieved.

When the relay RY1 is ON, that is, in the night lamp mode, the power supply reaches the switch SW2 via the diode D22. If SW2 is in the ON state, that is, in the state of 2-3 and 4-5 conduction in the figure, the power supply passes through the connection to the next controller of SO-1 and SO-2, and 2.4 night lamp connection power saving control Passing through the interface, the next lighting fixture can be linked and controlled to night lamp mode. Therefore, it is possible to make this controller the main night lamp switch simply by turning on SW2, and all connected controllers can be activated by connection and all can be linked together to control to night lamp mode. it can.

In FIG. 5, 2.3 battery charge, discharge control and protection, DC-IN is provided for charging an external battery. Since the battery selection and DC-IN are the same voltage, it is necessary to go through the booster circuit of the integrated circuit (IC) U7. Among them, J14 selects how much voltage of DC-IN is increased to be the upper limit voltage of charging. ZD4 to ZD6 in the figure are voltage stabilizing diodes having different voltage values. For example, the battery is 24V etc., ie, J14 1-2 pin short. At this time, the output voltage of the integrated circuit (IC) U7 is 30V, 36V or 48V obtained by adding the voltage of ZD4 to the voltage of the upper limit voltage DC-IN on the capacitor C23. The charging voltage is obtained by adding ZD5, ZD6, or ZD7 to DC-IN, respectively. Connect an external battery on the J17 connector. The above charging voltage charges the battery via the diode D35, the resistor RT12, and the transistor Q12. The combination of voltage stabilizing diode ZD10 and resistor R48 limits the maximum charging current. Its highest charging voltage is limited by the integrated circuit (IC) U7 and the selected ZENER (ZD4-ZD7).

The integrated circuit U11 optical isolation IC checks for power outages. When the AC-L and AC-N power supplies are lost, no current flows through the light emitting diode D42. In the C pole of the integrated circuit U11, the positive end of PIN 7 of U10A changes to HI, which causes U10A to output HI, the transistor Q13 to conduct, and the relay RY2 to operate. Battery power is provided to DC-IN via relay RY2. That is, the entire controller power supply is powered by an external battery. At the same time, the power failure signal is forced to enter the night lamp mode via the diode D51, the relay RY1 is operated, and the limited power is provided to the LED lamp for use. As a result, the external battery can light up the controller's LED lamp directly with less power and extend the usage time.

If the battery is continuously used, the voltage gradually decreases. When the battery voltage is discharged until the divided voltage of R55 and R57 becomes smaller than the selected Vref voltage, U12A outputs LOW. This passes through diode D41 and changes the PIN 7 positive end of U10A to LOW, which turns off transistor Q13. Thus, the relay RY2 becomes OPEN, the battery power supply is stopped, and the battery is protected from being excessively discharged.

The 2.4 night lamp connection power-saving control interface in Fig. 5 is the U17 optical isolation IC in the figure, which inspects the power supply of the existing wall switch. A general wall switch uses a two-wire switch to control a lighting fixture power source. Therefore, this interface detects the power source that lights the original lighting device. AC-L4 and AC-N4 in the figure are used for signal control. When the wall switch is ON, a current is passed through the light emitting diode D47, so that U17 outputs and U1DPIN 12 and 13 pins are LOW. On the other hand, when the wall switch is OFF, HI is output, and then the NLC is connected to the U16 microprocessor via the U1D output pin (see FIG. 6). Thereby, the command of whether to switch to a night lamp can be obtained by turning on or off the existing wall surface switch. The point is that it can be directly specified and used without the need for separate wiring and switches.

U19 provides an interface that can control the night lamp. If this controller wants to control the connection, set switch SW5 to ON. As a result, when there is a power input between SO1-1 and SO1-3, the U1D-PIN pins 12 and 13 are set to LOW and NLC is set to HI as controlled by AC-L3 and AC-N3. And can tell U16 to enter night lamp mode. Through the design of this interface, a single wall switch can control the lighting of a large area such as an entire building or a floor, and at the same time can be turned into a night lamp. In this way, the illumination power source that has kept the minute power and forgot to turn it off is turned off.

The 2.5 human body sensor PIR control interface shown in FIG. 5 similarly uses a light isolation IC U14 to switch the power supply to the control signal system. Thereby, the power supply of the existing wall switch can be provided to the human body sensor PIR. When the sensor detects that there is a person, it outputs a power source and turns on the light. Here, when the human body sensor PIR detects that there is a person, a current flows through the light emitting diode D45 in the figure, the C pole of the U14 light isolation IC sets U1C-PIN 8, PIN 9 to LOW, and U1C Output signal to HI and notify U16 microprocessor. In this way, the human body sensor PIR mode is activated, and when the presence of a person is detected, the lighting device group to be lit is turned on.

In the 2.6 microprocessor and peripheral equipment of FIG. 6, the program operation and control of the present invention must first be identified and processed by a wall switch on the U16 microprocessor. As a result, the four types of control signals, the night lamp control signal (NLC), the human body sensor (PIR) inspection control signal, the situation group control signal (GPC), and the intelligent operation and control signal (PRXD) that come from the power adapter are lit. Try to enforce the orders. The content of the lighting is based on the content set in the memory of U16. It reads the contents of G1 to G8 and MD1 to MD4 via U15 and U18 parallel conversion series ICs by U16 by setting the internal dip switch or the external setting control box, and stores them in the internal memory.

Separately, the two measurement signals are passed, and the voltage signal (AD1) and current signal (AD2) are the voltage (V) that drives the LED lamp at that time by the U16 internal linear conversion digital (A / D) circuit. You can know the numerical value of the current (A) that drives the LED lamp. Subsequently, a synergistic calculation is performed by an internal program, and further accumulation is performed to obtain watts (W) and power consumption (Wh). At the same time, it can be obtained via U15 parallel conversion series IC. Only when these LED lamps are gathered, it is possible to identify and record whether there is any abnormality, and to achieve the function of main failure reporting. Separately, the U16 microprocessor passes the U4 serial conversion parallel IC, and sends the signal of the lighting fixture to be lit to each control MOS from the diodes D23 to D30 (Q2 to Q9 in the figure). Finally, the U16 microprocessor can read the controller communication ID via U18, so that the SW4 (RS-485 address) settings are connected by the U9 RS-485 communication interface IC and the remote end server. Control and data storage are performed.

In the 2.7 LED lamp control and power consumption measurement interface shown in Fig. 6, there are a total of 8 POWER MOS drive circuits in the figure, which are composed of field effect transistors Q2 to Q9, and each set consists of one external LED lamp. (LED-OUT1 to OUT8 in the figure)

The first set will be described as an example. When G1 input is at HI potential, Q2 conducts. Conversely, if the input is LOW, Q2 will OPEN. If Q2 becomes conductive, the D6 indicator will light and the LED lamps connected to LED-COM and LED-OUT1 will light. RT4 is a protection resistor that overheats RT4 when overloaded, and the resistor has a large thermal change to limit and protect the current. Each other set of operating principles is also homologous.

In the figure, R2 and R13 are divided and connected to AD1, and the LED drive voltage is measured. The drive current of each set of LEDs gathers and flows to R36. U3A expands the voltage on the top surface of R36, and the output voltage of U3A is the AD2 voltage, which is directly proportional to the combined current of 1-8 sets of LEDs. Thus, with the U16 microprocessor, the internal A / D converter can measure AD1 and AD2, and know the LED lamp drive voltage (V), current (A), watt (W) and power consumption (Wh).

The 2.8 external control setting interface of FIG. 5 mainly provides one 15 PIN connector. PIN 1 to PIN 8 of the connector are connected corresponding to G1 to G8 of 2.7 and control whether to conduct to Q2 to Q9. In this way, eight external LED lamp sets of LED-OUT1 to OUT8 are controlled. The necessary power supply is obtained by stepping down from the 24V power supply with R85, and the control right is acquired by pin 13 of J3. PIN 13 in the figure is pulled to the B pole of Q11. Normally, the B pole of Q11 is at HI potential, which causes the C pole of Q11 to go LOW. At this time, the output of U4 is controlled by the U16 microprocessor IC.

After starting to use the external setting control box, PIN 13 of this interface changes to LOW. As a result, the U4 output expires, and the LED lamp control right is controlled by the interfaces J13-1 to J13-1. Its purpose is to provide another kind of circuit structure in the event of a circuit failure and to provide a simple emergency lighting control scheme.

Separately, this setting control box provides four sets of situation group settings. It includes two sets of group control lighting settings, one set of anthropometric lighting settings, and one set of night lamp control lighting settings. These set values are read by U16 microprocessor IC through U15, U18 parallel variable series connection IC, and G1 to G8 and MD1 to MD4 are read. The contents at that time are stored in the memory inside the U16, and when these control commands are received, it becomes the basis for lighting the LED lamp.

The 2.9 optical isolation carrier communication control interface in FIG. 6 detects the carrier signal during the positive half cycle by the optical isolation IC U8. After the original wall switch is replaced with a single intelligent operation and control device, the device modulates to a single byte serial connection communication (UART) signal near the highest half-round maximum. The signal modulated instantaneously changes the UART from HI to LOW communication signal instantaneously. It quickly changes to the ON or OFF signal at the maximum value of the positive half circle. This signal is faithfully represented on R53, passed through U1B, converted to a PRXD signal, and then the content of the carrier signal is identified by the U16 microprocessor to achieve the purpose of intelligent control.

The 2.10 wall switch group control interface in Fig. 6 uses the optical isolation IC U5 as the AC-L2 and AC-N2 power supply, converts it to the control signal system, and directly uses the existing wall lighting switch wiring and switches. Connect the power supply originally provided to the lighting fixture to AC-L2 and AC-N2 in the figure. When the switch is ON, current flows to the light emitting diode D37, U1-PIN 1 and PIN 2 on the C pole of U5 become LOW, U1A output GPC becomes HI, notifies the U16 microprocessor, and the situation group control mode is set. to start.

The 2.11 RS-485 communication interface in FIG. 6 mainly converts U16 serial connection communication signals, SRXD and STXD, into RS-485 differential signals by a U9 RS-485 conversion IC. As a result, the RS-485-A and RS-485-B signals are remotely transmitted to a system control center such as a server or a PC. This allows the system to remotely collect power information and luminaire controls for each LED lamp.

The attached intelligent operating device of FIG. 7 utilizes the existing wall lighting switch wiring and position. Its external shape is similar to the existing switch box. The power acquisition and communication interface are both the existing two wires on the wall switch. The BD1 bridge rectifier in the figure acquires power from the existing two-wire electric wire of the wall surface switch, and supplies it to the device via D105 and C105 for use. U107 is a power adapter IC that supports the resistance value design of peripheral equipment R106 and R109, and obtains the 5V power supply necessary for this device from the local power.

Separately, the U105 optical isolation IC can pass through D102, R102, and ZD101 and detect the positive and negative half cycles of the local power. The detected local power positive and negative half-circumference signals are directly input to the U104 microprocessor via U101-PIN3 and are used as a synchronization signal of the signal to be transmitted.

In other words, U104 calculates the electrical angle timebase of the highest value of the city power half-round based on the signal timebase of U101-PIN3. Furthermore, the signal to be transmitted is passed through the U101 in a timely manner, the Q109 POWER MOS is driven, the digital signal is temporarily turned on or off, placed on the power line, and the maximum value of the positive half-circumference is around 90 degrees electrical angle. Using a power line, the digital signal to be transmitted is converted into a pulse signal of a two-wire electric wire presence / absence current.

The magnitude of this pulse current is controlled by R8, and this pulse current is detected by the 2.9 optical isolation carrier communication control interface. In addition, it is reduced to a digital signal, received and identified by the U16 microprocessor, and the communication content is enforced to achieve the purpose of intelligent control of the lamp.

Separately, SW101 to SW108 in the figure are individual control operation interfaces of eight LED lamps to be controlled correspondingly. SW109 to SW112 are situation group collective control operation interfaces. D108 to D120 are indicators corresponding to each other, and are controlled by the U104 microprocessor through serial conversion parallel ICs U108 and U109. As a result, the entire lighting control system is made intelligent, and no new piping or wiring is required.

In the attached external setting control box of FIG. 8, J24 in the figure is connected to J3 of the 2.8 external control setting interface. When SW8 is set to ON, the setting and control functions of this external setting control box are activated. At this time, PIN 13 is LOW, which causes the internal LED lamp control IC U4 to expire. The LED lamp control permission is controlled by this control box. At this time, the on / off of the LED lamps 1 to 8 can be directly controlled by moving the switches corresponding to SW1 to SW8. At the same time, in a certain lighting combination arrangement, if MD1-MD4 press the corresponding switch, the internal microprocessor (U16) memorizes the group type set at that time, and U16 receives the command Sometimes it is the basis for controlling the lighting.
