Description

Luminaire control functional unit for electric lighting zone control system

Technical field

The invention relates to the technical field of electric lighting partition control, in particular to a lamp control function unit applied to an electric lighting partition control system, which is particularly suitable for a digital electric lighting control system, and needs to set a light of a lighting controller of a plurality of lighting scenes. A switch device is controlled, and a light scene setting device that interfaces with the light control switch device. Background technique

With the advancement of electronic components and electronic control technology, the electric lighting process has developed into a digital control system, in which the Digital Addressable Lighting Interface (DALI in Europe and America) is specified in Annex E of IEC60929. Most representative. This was originally a specification for fluorescent dimming control, but it was gradually developed into a control system specification covering all electric lighting systems due to its reliability, simplicity, and reasonable price. Especially in the face of worldwide energy and environmental issues, energy-saving technologies are becoming increasingly important, and lighting systems that can be controlled automatically are becoming necessary.

The digital electric lighting control system was originally an extension of the calculator technology. The lighting control system that uses the serial bus to transmit control information such as the network is very powerful, but the price is too high and unreasonable. Restrictions, only for some special purposes, are not universal.

The digital addressable lighting interface system was developed successfully in Europe and gradually accepted by the world. The architecture consists essentially of a bus power supply, at least one controller, and a light fixture with a digitally addressable light interface receiver. Each digitally addressable light loop can control up to 64 individual luminaires, each of which is assigned an address code at initial setup. According to this address, the system can issue instructions for each luminaire separately. However, in practical applications, the luminaires should be grouped first. After storing the group data in the memory of each luminaire, as shown in European Patent EP90100465.6 (USPAT5352957), the instructions can be directly applied to the group. A loop can set up to 16 groups (0~15). Each fixture can belong to several groups at the same time. However, depending on the actual system, some products only allow one group to be set.

The use of the group is very convenient and important. For example, each room is at least one group, so that the controller can control the whole room as a whole, and the controller in the room must also set its control group in advance, so that the instructions can be correctly issued without cluttering. Another example is an office, assuming it includes several rooms and a conference room. For In order to meet the requirements of energy saving, each room must be individually controllable to automatically turn off the illumination or reduce the brightness when no one is present. If the lighting of each room is to be controlled separately, a group code must be assigned separately. The controller and sensor associated with this room must also be set with the same group code. The lights in the conference room may need to be divided into at least three groups, such as the top of the podium, the conference table, and the two sidelights to accommodate different needs such as speeches, deliberations, multimedia screenings, and briefings. In order to facilitate the direct command of each group of lights, each room can be equipped with a dedicated group controller. As long as the group button of the group controller is pressed, the group of lamps will accept the command. Of course, these connections must be pre-set. OK, otherwise the controller and the controlled luminaire will not be able to connect. For the grouping method of the controller, reference can be made to the German patent DE4327809.4, (USPAT.5544037). The common group controller has four group selection keys.

After the grouping is completed, each group of lights can be separately adjusted to an appropriate brightness to form an overall lighting scene. Some locations, such as multi-purpose conference rooms, may require several different lighting scenarios to suit different needs. In order to avoid the trouble of frequent adjustment, the lighting scene controller can be used to pre-store the data of each group, brightness and other data related to each lighting scene, and only need to press the scene selection button to retrieve the original design. Fixed, common lighting scene controllers generally have 4 to 8 scene keys to choose from.

The addressability of digital addressable lighting interface systems is characterized by the grouping, scene setting, and dimming of the entire system. However, the initial grouping, setting the scene, and setting the brightness can be very complicated and require professional and specialized tools.

A digitally addressable lighting interface system loop that can have 64 controllers, each with its own address (the sensor is also a controller). Each controller must be pre-set. It has been shown through practical application experience that a digitally addressable light interface loop whose luminaires can only be divided into up to 16 groups is often insufficiently used, thus creating a limitation. For example, when the number of rooms is a little more or the lighting scene is more complicated, it is impossible to cope, and another loop must be added.

In addition to the simple lighting function in daily life, many places often need to set multiple lighting scenes to meet the actual needs. These needs are sometimes functional, sometimes for energy savings, and sometimes for both. For example: general halls and walkways, all work should be bright when cleaning work, usually half light; merchandise display space, the key theme of the display should be brighter, the background should be darker, to create contrast, highlight the theme, but When doing cleaning work, it should be fully lit; when meeting in the conference room, the lighting on the conference table should be brighter, the surrounding should be darker, when the briefing is made, the whole room should be darker, only the projection screen near the desk should be completely dark. Eli projected images. Other living spaces such as living rooms and restaurants can also use the changes in lighting scenes to create an energy-saving and colorful living atmosphere.

This overall lighting scene atmosphere, in addition to making people feel comfortable and happy, because the lighting is not always in a state of full light, it also achieves energy-saving purposes. In order to achieve the control effect of the lighting scene, if the digital addressable lighting interface lighting control system is used, as described above, each luminaire must be grouped, and each group of lights is adjusted to the required brightness, and then the groups of each group are Data such as brightness is stored in the scene controller, and the scene controller recalls the set scene according to the button. Although the digital addressable lighting interface lighting control system can directly control each luminaire, it is not practical and inconvenient for the average user. The actual lighting control must be performed by means of the scene controller or the group controller.

Let's take an ordinary conference room as an example to illustrate the lighting layout. As shown in Figure 1, Figure 1 is a schematic diagram of the layout of the conference room lighting.

The lamps in the entire conference room are classified into the first group, including all the lamps, and the lamps on the conference table are classified into the second group.

2, including lamps 2-1, 2-2, 2-3, the lamps on the wall side are classified into the third group 3, including lamps 3-1, 3-2, 3-3, 3-4, the front platform The lamps are classified into the fourth group 4, including the lamps 4-1, 4-2, 4-3. The controller SC has four scene selection buttons and one total button. As long as the scene button is pressed, the entire field light is in place. The settings of each lighting scene are as shown in Table 1 below:

Table 1

It can be seen from Table 1 that basically the control of the lighting scene is achieved by changing the brightness of the light source of each luminaire, and grouping the luminaires for the convenience of setting and executing instructions. If the scene brightness setting of each luminaire can be easily performed, and each luminaire can easily receive and execute scene instructions directly, grouping is not necessary, thus eliminating many restrictions.

The brightness of the light source can be changed to full brightness or off, and the simple switching type two-stage dimming; it can be semi-bright, 3/4 bright, full bright, off and off four-stage dimming; or can be fine-tuned dimming Ways, for example: 16th order dimming.

Because of the wide variety of light sources, such as incandescent lamps (including halogen lamps), fluorescent lamps, cold cathode fluorescent lamps, rolling gas discharge lamps, light-emitting diodes, etc., the method of adjusting the brightness is also different. Incandescent lamp multi-use change two-way controllable The excitation phase of silicon is controlled, as shown in U.S. Patent No. 5,821,704; the dimming of fluorescent lamps is much more complicated. For fast start-up and lifting efficiency, fluorescent lamps are driven by high-frequency, and when dimming is used, variable inverters are used. The frequency of the device, or changing the on-time of the fixed-frequency inverter to change the brightness, as shown in U.S. Patent Nos. 5,187,414, 5,872,429.

With the advancement of digital control technology, regional overall lighting control has been completely replaced by digital technology. Digital lighting control systems use wave width modulation (PWM) modulation methods to convert digital commands into simulations of light source driving circuits. Modulating the oscillation frequency of the inverter of the light source driving device or the conduction time of the fixed frequency AC power supply, the PWM modulation mode can be finely fine-tuned, for example, the DALI system has a 256-step (including off-off) dimming capability. .

The 256-step dimming capability is too much for practical applications in most everyday life, thus creating a waste. The ideal lighting scene control system should be simple and simplistic, and can be equipped with a finer dimming device or a simple switch. At the same time, it can be applied to all kinds of different light sources, and the price is low.

The digital addressable lighting interface control system is relatively economical in terms of price compared to the lighting control system based on the communication bus of the calculator, but it is still a relatively expensive system. Especially for developing countries that need automated lighting control technology to cope with energy savings, the price is unacceptable. Therefore, an electric lighting control system that is more economical and easier to use is highly anticipated. Summary of the invention

The present invention will be further described in detail below with reference to the accompanying drawings, and the accompanying drawings.

For ease of explanation, the present embodiment will employ a light scene command that is compatible with the Digital Addressable Light Interface Specification (DALI), as shown in Tables 2 and 3, where Table 2 is the system command and Table 3 is the interval command.

For example, the system-wide broadcast instruction of the present invention can be set to two bytes, and the first byte is FF, as shown in Table 2:

table 3

The structure of the system instruction and the interval instruction is shown in Figure 2 and Figure 3. Figure 2 is a schematic diagram of the system instruction. The system instruction consists of 1 start bit 16-bit instruction data and 2 stop bits, 16-bit instruction data, divided into 2 bytes, the high byte is the system control byte, and the low byte is the lamp operation byte. Figure 3 is a schematic diagram of the interval instruction. The interval instruction consists of one start bit, eight bits of command data and two stop bits. The interval command is the lamp operation command.

As shown in FIG. 4, FIG. 4 is a block diagram of a lamp control function unit applied to an electric lighting zone control system according to the present invention. The luminaire control function unit applied to the electric lighting zone control system includes a content addressable light control switch device 39 and a light scene setting device 42. The content addressable light control switch device 39 is configured to convert the control signaling transmitted on the bus 2 into a scene control switch signal and output the signal to the light scene setting device 42. The light scene setting device 42 is configured to decode the scene control switch signal received from the content addressable light control switch device 39 and the light scene data signal set by itself, and output the decoded result to the light source driving device 34. The switch and brightness of the light source 35 are driven.

The content addressable light control switch device 39 is generally made of a single-core semiconductor integrated circuit, and includes at least one memory unit. The memory unit is a read-only memory ROM or a non-volatile memory device for storing light control command data. Each memory unit has an instruction data comparison device, and the comparison result is driven by a driving transistor, each line is an instruction, and there is a comparison line.

After the light control command transmitted on the bus 2 enters the information processing device 41 and is restored, the digital data in the light control command enters the shift register 38, and the clock signal enters the clock controller 40, which is the digital data of the system command portion in the shift register 38. The high byte, after being decoded by the system instruction decoder 44, generates a coincidence signal into the content addressable light control switch device 39 if it is a related instruction of the lamp; if the control command received by the bus is an interval instruction, The system command decoder 44 directly generates a coincidence signal, and the input content can be addressed to the light control device 39 to be in the execution function state; the lower byte of the digital data in the shift register 38 is the interval command, which is passed through the clock controller. The clock signal is controlled to enter the interval command decoder in parallel, that is, the content addressable light control switch device performs command comparison.

The specific process of the content addressable light control switch device for command comparison includes: the content addressable light control switch device 39 controls the actual light control portion of the digital data in the control signal and the control signal stored in the memory unit of the ROM itself. Let the data be aligned in the column. For the same memory unit, keep the comparison line of the line of the memory unit high, and generate a corresponding scene control switch signal to output to the light scene setting device; To compare memory cells that are not the same, pull the comparison line of the row where the memory cell is located to a low level, and keep the comparison line of the row of the same memory cell in each column high.

The content addressable light control device 39 is the core of the present invention. Content addressable technology is a memory addressing method developed on the basis of random access memory. It can compare the input information data with all the data in the content addressable memory device at the same time. The information content directly determines the correct address of the relevant memory data. This fast addressing performance is very important for network communication. Its operation can be completed by pure hardware, without the need of a central processing unit or a microcomputer, and does not occupy software operation time. Content addressable technology also plays an important role in information compression coding and decoding and image processing. As shown in U.S. Patent No. 3,402,394, 34,1985. The invention utilizes the content addressable technology to directly convert the instruction for driving the light source into the corresponding switching signal according to the instruction content, and each of the switching signals activates its corresponding and preset light source driving circuit, thereby completing The expected action of each instruction.

The light scene setting device 42 includes a light control switch signal input terminal, a dial switch 36, and a decoding circuit 33. Wherein, the light control switch signal input end is correspondingly connected with the switch signal output end of the content addressable light control switch device. The DIP switch 36 is used to set the brightness coding of the individual lighting scenes for the decoding circuit to drive the light source driving device. The decoding circuit 33 is configured to decode the scene control switch signal received from the content addressable light control switch device 39 and the light brightness data of the individual light scene set by the dial switch 36, and output the decoded result to the light source drive. The device 34 drives the switch and brightness of the light source 35.

Further, a latch circuit 43 is further included between the content addressable light control switch device 39 and the light scene setting device 42 for holding the light control switch signal input by the content addressable light control switch device 39, and the saved light The control switch signal is output to the decoding circuit 33 of the light scene setting device 42.

The latch circuit 43 includes at least a latch pulse controller LC and a latch, after receiving any one of the unique light control switch signals input by the content addressable light control switch device 39, The latch is executed to latch the switch signal into the latch corresponding to the control command. The number of latches is the same as the number of light control command switch signals, and each latch corresponds to a light control command signal.

Each set of light scene data signals set by the dial switch has a one-to-one correspondence with each set of light scenes.

Referring again to FIG. 4, the content addressable light control switch device 39 converts the digital instructions, such as the instructions shown in Tables 2 and 3, to the switch signals via a latch circuit 43 by directly decoding the instructions according to the contents of the instructions: m0 ON ( Full light), ml off, m2 scene 1, m3 scene 2, m4 scene 3, m5 scene 4, after each switch signal passes through the light scene setting device 42, the light source driving device 34 is driven to drive the light source 35, and the light source 35 can It is a halogen lamp, a tubular fluorescent lamp, a compact energy-saving lamp, a light-emitting diode, etc., and the light source driving device 34 can be a relay, an electronic transformer, a ballast, etc., and the light field setting device 42 can set each via the dial switch 36. The brightness of the light source in each lighting scene.

The content addressable light control switch device 39 has various switch commands related to lamp operation, and the memory unit is made of a read only memory or other non-volatile memory device. The instructions stored in this embodiment include: Light), turn off, scene 1, scene 2, scene 3, scene 4 and other lighting control commands. As shown in Table 2 and the addressable light control switch device 39, 0, 1 in the memory unit C. After the digital light control command enters the information processing device 41 via the information transfer bus 2 and is restored, the digital data enters the shift register 38, and the clock signal enters the clock controller 40. In the light control command, the high byte of the 2-byte instruction 37 is the system instruction part of the communication protocol, and the low-order byte of 37 is equivalent to the byte of the interval instruction 38 is its actual lighting control part, the data of byte 38 and The memory command data of the content addressable switch 39 is aligned in the column, and the alignment is completely in accordance with the alignment. (Matched), maintaining a high level, generating a corresponding output signal (m0-m5), fed to the decoding device 33 of the light scene setting device 42 via the latch circuit 43 to drive the light source driver 34 and the light source 35 .

In Fig. 4, 44 is a decoder of the system command portion. For example, when the system command is broadcast (11111111), the AND gate 441 outputs a high level, and this data is latched into the latch DS when 41 detects the stop bit. The buffer A is fed into the content addressable light control switch 39, and R is a current limiting resistor when charging m0-m5. When the comparison is made, the memory cells of each column are simultaneously compared, and the memory cells that do not match the row will pull the m0-m5 correlation line associated with the row of the cell to the low level, only The m0-m5 alignment line of a uniform column can maintain a high level and is latched into the corresponding latches D0-D5 to drive the decoder 33. The clock management device 40, after the information processing device 41 detects the stop bit, generates a pulse L that locks m0-m5 into D0-D5. The LC is a latched pulse L controller that can only be latched when there is a complete match between the m0-m5 compare lines. After the information processing device 41 detects the start bit, it performs decoding and clock recovery. When the input command is recognized as a non-system command, 41 will output a high level to 46, and lock the latch after detecting the stop bit. DA.

As shown in FIG. 5, FIG. 5 is a block diagram of a light scene setting device in a first embodiment of the present invention. In this embodiment, the controlled light source 35 has only two states of full light or off. The schematic diagram of the embodiment is a block diagram of an embodiment of the two-segment 4 light scene setting device.

Among them, 36 is the setting of the light dip switch, including SS1, SS2, SS3, SS4, respectively, to set the lighting state of scene 1 to scene 4. 33 is a decoding circuit, which is decoded according to the switch signal outputted by 43 of Fig. 4 and the light set by the dial switch 36. For example, when the input command is 00000000, the comparison line ml (off) is high, and the remaining m0, m2, m3, m4, m5 are low because the comparison does not match, when the reception is completed, The high level of ml is locked into D1, and its output Qml resets the latch 330, so that the output terminal Q of 330 is at a low level, so that the solid state relay 34 is turned off, and the light source 35 is turned off. - .

If it is desired that the light source 35 is fully illuminated in the light scene 1, the position switch SS1 corresponding to the scene 1 is set to the "bright" position, that is, the open position, and the input 2 of the AND gate 331 is high. When the light scene 1 command 00010001 is input to 39 of FIG. 4, m2 is high level due to complete coincidence, and the high level of the input terminal 1 and the input terminal 2 of the Qm2 input AND gate 331 causes the AND gate 331 to output the 髙 level. And the OR gate 335 is locked into the latch 330, so that the output terminal Q of the 330 is at a high level, and then the solid state relay 34 is activated to make the light source 35 illuminate, and the light state of the scenes of scenes 1 to 4 can be set by corresponding lights. The DIP switches SS1, SS2, SS3, and SS4 are set to be either light or dark. The function of the inverter 336 is to reset 330 when the output of 335 is low.

As shown in FIG. 6, FIG. 6 is a block diagram of a light scene setting device according to a second embodiment of the present invention. In this embodiment, each lighting scene can have 100% (full brightness), 75%, 50%, 0% (off) 4 settings Select the state, each scene has 2 DIP switches, as shown in Figure 6 SS 1, SS2, SS3, SS4 for setting. The schematic diagram of this embodiment is a block diagram of an embodiment of a 4-segment 4-light scene setting device.

When the control command is 00010001, the switch control signal m2 of the light scene 1 is high level, and the remaining m0, ml, m3, m4, m5 are all low level, and the high level of m2 makes the selection circuit 71 perform the function. The low level of m3, m4, and m5 causes 72, 73, and 74 to be in the de-energized state.

When SS 11 and SS12 in the light scene setting switch SS1 are both closed, the output of the AND gate 714 is high, and the high level enters the OR gate 76 to reset the latch 79, and the output terminal Q of 79 is Low level, the light source is turned off.

If SS11 is closed and SS12 is open, the output of AND gate 713 is high. This high level is simultaneously input to OR gate 78 and is input to OR gate 75 via OR gate 715. OR gate 75 latch sets 79, Q At a high level, the light source driver 34 enters a full bright (100%) operating state, but at the same time the OR gate 78 outputs a signal to the light source driver 34 to make the brightness of the light source 35 50%, as will be understood by those skilled in the art of electrical lighting control. The output of 77, 78 can change the variable potentiometer value associated with the brightness of the light in 34, thereby changing the brightness of the light, which is not detailed here.

The lights shown in Figure 5 and Figure 6 The scene setting device has four lighting scenes for setting and combination. Although the brightness setting of each lighting device has 2 segments and 4 segments, the interface between each lamp and the four scene content addressable switches is the same.

Therefore, the same light scene control switch can be configured with different light sources. The brightness variation accuracy of the light source can also be selected according to price and function, so that the lighting scene control becomes simple and simple, easy to operate, plug and play, and not A complicated setup procedure is required.

As shown in FIG. 7, FIG. 7 is a schematic diagram of an electric lighting partition control system for applying a lighting control function unit according to the present invention.

The communication protocol of the system divides the instructions into system instruction group and interval instruction group, as shown in Table 2 and Table 3. In Figure 7, 37 is a system instruction consisting of two bytes of length, 38 is an interval instruction, only one byte, and its actual encoding can be as shown in Table 2 and Table 3.

The highest bit of the system instruction is "1", that is, 2 bytes of 16-bit 0x8000 or more can be classified into system instructions; the highest bit of the interval instruction is "0" for resolution. The instruction sent by system controller 7 is a 2-byte length system finger. Therefore, the command transmission is recognized by a start bit, and its termination is recognized by 2 stop bits. As shown in Fig. 2 and Fig. 3, Fig. 2 is a schematic diagram of system instructions, and Fig. 3 is a schematic diagram of interval instructions. The transmission path of the system command is as shown by 9 in Fig. 7, which can be entered into the b area by the area a through the picture boundary repeater 6. As shown in Figures 37 and 38, the luminaire can accept a 2-byte system command 37 and can also accept a 1-byte interval command 38.

The interval controller 8 and the sensor 4 can only transmit the interval command, so the command cannot pass through the picture boundary repeater 6, and cannot enter the b area, so it is valid only in the zone a region to which it belongs, and 10 is the interval command transmission path. Cross the picture boundary repeater 6.

As shown in FIG. 8, FIG. 8 is a structural block diagram of the picture boundary repeater 6 in the electric lighting partition control system provided by the present invention. The addressing instruction architecture of the picture repeater is similar to the grouping instruction in the DALI communication protocol. It is easy to integrate with the DALI system through the bridge technology. A bridge is a conversion device that combines two different systems. It is a common technique in the field of network communication technology and will not be described in detail here.

The relay controller 63 is configured to perform edge detection, waveform reforming, and start bit detection on the digital information received from the optical isolator 62, and identify system commands or intervals by comparing the highest bits after the start bit. The instruction temporarily stores the recognized system command into the shift register 64, and outputs the system command to the control device 65 or temporarily stores the system command into the shift register 64 when the control gate 65 is in the off state, The interval instruction is truncated.

The shift register 64 is used to hold digital information input by the relay controller. The control gate 65 is for driving the switching device of the downstream bus 2'' power supply according to the received system command to transmit the system command to the next interval. Collision recognition The detector 66 is used to monitor the collision state, and the control gate 65 is cut off when the collision state is detected.

The retransmission controller 67 is configured to send an instruction to the relay controller 63 after a predetermined time interval after the collision occurs or the address comparison coincides, instructing the relay controller 63 to perform the system instruction temporarily stored in the shift register 64. Resend all.

The two-phase digital information entering the relay controller 63 is also driven by a control gate 65 to drive the switching device of the downstream bus 2" power supply 68, which is not shown, to transmit information into the b zone, before being decoded. When the collision recognition detector 66 detects the collision state, the control alarm 65 is cut off and stops entering the b zone. However, the storage operation of the shift register 64 does not stop until the relay controller 63 detects that the two stop bits are completed. The storage action of the shift register 64 is stopped after being trusted.

After the retransmission controller 67 waits for an appropriate time delay, the relay controller 63 is instructed to perform retransmission. When retransmitting, the digital data stored in the shift register 64 is first subjected to two-phase modulation coding, and then enters the control gate 65 to drive down. The power supply 68 of the bus transmits information to the downstream bus 2".
