Description

Lamp controller with single lamp addressing function

Technical field

The invention relates to the technical field of electric illumination zone control, in particular to a lamp controller with single lamp addressing function, in particular to an electric lighting zone control system, which can set multiple lighting scenes and can accept overall lighting scene control. The command, in turn, is capable of accepting a single lamp control command, a lamp controller having a single lamp addressing function. 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) is referred to 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. Its architecture, consists essentially of a bus power supply, at least one controller, and a light fixture with a digitally addressable light interface receiver. Each digital 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 issued for 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. In order to meet the requirements of energy saving, each room must be individually controllable, and it can automatically turn off the illumination or reduce the brightness when no one is present. Degree. 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 presentations, 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 light 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 lighting 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 cannot be handled, 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 before As described in the article, each luminaire must be grouped, and each group of lights is adjusted to the required brightness, and then the group brightness of each group is stored in the scene controller, and the scene controller is set back according to the button. Scene. 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 whole conference room are classified into the first group, including all the lamps. The lamps on the conference table are classified into the second group 2, including the lamps 2-1, 2-2, 2-3, and the lamps on the wall side are classified. The third group 3, including lamps 3-1, 3-2, 3-3, 3-4, the lamps of the front platform are classified into the fourth group 4, including lamps 4-1, 4-2, 4-3 controller SC There are 4 scene selection buttons and a total button. As long as the scene button is pressed, the entire field light is in place. However, this convenience is based on complex hardware and software systems. The setting procedure is complicated and the price is high. For developing countries that need automatic lighting control technology to cope with energy saving problems, the price is high. It is unacceptable. Therefore, a more economical and easier to use electric lighting control system is highly anticipated.

The settings of each lighting scene are 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 the limitation of up to 16 groups.

In order to relieve the restriction by grouping and to waive the complicated setting procedure, the Chinese Patent Application No. 200610076528.2 proposed by the applicant of the present invention is entitled "Electrical Lighting Control System and Control Method Separated by Painted Repeater" In the patent case, a solution is proposed, which is a reference document of the related patent case of the present invention.

Table 1 also shows that the change of the brightness of the light source can be full bright, off, simple switching two-stage dimming; can be semi-bright, 3/4 bright, full bright, off and off four-stage dimming; A fine-tuned dimming method, such as: 16-step dimming. Very fine dimming of the 255 steps, as specified by the Digital Addressable Lighting Interface, is often too much and wastes.

The light level of each light scene can be completed by the light scene setting device 42, and the light scene control command can be directly executed by the content addressable light control switch 39. These actions are transparent and direct, and do not require complicated settings. program.

In order to achieve each luminaire, the control command can be directly received without setting a program, and another name proposed by the applicant of the present invention and the application is "a luminaire control function applied to the electric lighting partition control system. The "Unit" application proposes a technical solution for controlling the light with a content addressable light control switch.

The content addressable technology is a memory addressing method developed on the basis of random access memory. Compared with the traditional memory device, the method of pointing to an address and then finding the memory content is different, and the input information data can be The content addressable all the data in the memory device, and the comparison is performed at the same time, and the correct address of the relevant memory is directly determined by the input information content. This fast addressing performance is very important for network communication, and its operation can be performed by pure hardware. Complete without having to resort to a microcomputer or central processing unit, without taking up software operating 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 content addressable light control switch for electric lighting control uses content addressable technology to directly convert the command for driving the light source into the corresponding switching signal according to the instruction content, and each switching signal starts its corresponding , a preset light source driving circuit to complete the expected action of each instruction.

This content addressable light control switch can be fabricated from a semiconductor integrated circuit without the need for a microcomputer or central processor, so the price can be reduced. The practical application is conceptually the same as a simple selection switch, so no special personnel training process is required and no special tools or software knowledge is required.

The light scene setting device is used for providing a connection between the content addressable light control switch and the light source driving circuit, and is integrated with the driving circuit of each light source, and the actual circuit is driven by the light source driving circuit and The dimming effect is different, but for the user, it is only necessary to perform the action of dialing the code to set the brightness of each scene, so it is easy to operate, and has the friendly features of plug and play.

However, in addition to controlling the overall lighting scene, in some more personal spaces, such as rooms in high-end hotels, living rooms in homes, etc., it is often necessary to switch or dim the individual lamps to meet everyone. The same needs. Some special luminaires, such as chandeliers, often require special treatment. In order to meet the need for separate control of individual luminaires, the above-mentioned content addressable light control switches must have single-lamp addressing. .

The content addressable memory device has a function of setting an address, which means a program for writing address data to a content addressable memory device. The conventional method of writing data in a content addressable memory is to use a word line. Line, control the word line to be written, activate the memory word line, open the memory cell write gate of the relevant word line, and then write the data side by side into each memory unit of the word line.

This traditional write procedure will complicate the circuit architecture and clock controller of the content addressable light control switch, requiring control by the microcomputer controller. This will increase the price of the product. In order to achieve the purpose of improving lighting quality and energy saving, price is an important factor. Therefore, how to increase the addressing function while reducing the price and being easy to use is an important issue. Summary of the invention

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 command of the present invention can be set to two bytes, and the first byte is FF, as shown in Table 2 - Turn off FF00 11111111 00000000

All FF05 11111111 00000101 Scene 1 FF11 11111111 00010001 Scene 2 FF12 11111111 00010010 Scene 3 FF13 11111111 00010011 Scene 4 FF14 11111111 00010100

(J can be specified as a single byte, as shown in Table 3:

Shutdown 00 00000000

Scene 1 11 00010001

Scene 2 12 00010010

Scene 3 13 00010011

Scene 4 14 00010100

Table 3 The system command decoder 44 technique of Figure 2 is a technique that is readily apparent to those of ordinary skill in the art, such as by means of AND gates, repulsions or gates, and with the manual addressing of the present invention. The addressing means are not directly related, and are simplified and omitted in FIG. 3 for simplicity.

Referring again to FIG. 3, the content addressable light control switch device 39 directly decodes the digital command according to the contents of the command, and converts it into a switch signal via a latch 43: m0 on (full light), ml off, M2 scene 1, m3 scene 2, m4 scene 3, m5 scene 4. M6, m7, m8, m9 are the switching signal lines associated with a specific address, m6 is on (full light), l is off, m8 is dimming, m9 is dimming. After each of the switch signals passes through the light scene setting device 42, the light source driving device 34 is driven to drive the light source 35. The light source 35 can be 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 scene setting device 42 can be set via the light setting device 36. , set the brightness of each light source in each lighting scene.

The content addressable light control switch device 39 has various related commands stored therein, and the memory unit is made of a read only memory or other non-volatile memory device, and each memory unit has a comparison with the received command bits. The device, the comparison result drives the comparison line via a driving device. In the content addressable light control switch device 39 Among the switching instructions of the memory, the overall lighting controller includes: ON (full bright), off, scene 1, scene 2, scene 3, scene 4 and other lighting control commands, and the switching signals belonging to the single lamp control are _m 6, m7 , m8, m9.

After the digital light control command enters the information data restoration device 41 via the information transmission bus 2 and restores the data and the clock signal, the digital data enters the interval instruction 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 as shown in FIG. 2 is the system instruction part of the communication protocol, and the low byte of 37 is equivalent to the byte of the interval instruction 38 is its actual lighting control part. The data of byte 38 is aligned with the read-only memory instruction data of the address-addressable 39, and the fully matched (output) line generates a corresponding output signal (m0-m9), and is detected at 41. After two stop bits are obtained, a latch pulse L is generated, latched into the D-type latch 43, fed into the decoding device 33 of the light scene setting device 42 via the D-type latch 43, and driven after decoding. Light source driver 34 and light source 35.

The data latch of the D-type latch 43 is controlled by the lock controller LC, when m0~! N9 can be latched when there is a match line. R is the current limiting resistor when charging m0-m9. When the comparison is made, the memory cells of each column are simultaneously compared, and the memory cells that do not match the matching will pull the related m0-m9 comparison line to the low level, and only the columns are consistent. The m0-m9 comparison line can maintain a high level.

The 0th line to the 5th line interval instruction of the memory array of the content addressable light control switch device 39 is valid for all the lamps of the executable interval instruction; the 6th to 9th lines are associated with the instruction of the specific address, line 6 The memory cells in the second column to the fifth column of the ninth row are the addressing bits 390, which are: the second column is the address first bit A1, the third column is the address second bit A2, and the fourth column is the address third. Bit A4, column 5 is the fourth bit of the address A8. A total of 16 addresses can be set for 4 address bits A8, A4, A2, and A1.

Table 4

Each luminaire can be selected with a controller capable of addressing capability or a controller without addressing capability. A controller without addressing capability can only perform interval command actions, receive system broadcast commands and interval commands, and select The addressable controller can accept the single lamp control command. For the addressable lamp, the switch can be switched on and the brightness can be adjusted up or down. The setting of the single lamp address is performed by the dial switches SA8, SA4, SA2, and SAl. The data values of the input terminals DA8, DA4, DA2, and DAI of the D-type latch are set by the dialing codes SA8, SA4, SA2, and SAl. The setting is determined and locked into the latch when the system is powered up. As shown in FIG. 4, FIG. 4 is a circuit diagram of a content addressable memory device in a content addressable light control switch device provided by the present invention. Two of the inverters 303, 304 form a bistable memory cell C. When the memory data bit line AB is at a high level, ^" is a low level, and if the word line W is at a high level, the write triode is written. When 301, 302 is turned on, the input of the first node inverter 303 of the memory is high, and the output thereof is low for the second node, and this state will be latched. At this time, the comparator 305 is 305. In the open state, the comparator transistor 306 is turned on.

If the input addressing data bit line B is at a high level, ¥ is low, that is, when the input data B is the same as the stored data AB, the high level of B cannot be broken by the low level control of the second node. The transistor 305 of the state is introduced into the gate of the driving transistor 307 of the comparison line m, and the transistor 307 is also in an open state, and the comparison line m is kept at a high level.

If the input data bit line B is low level and ¥ is high level, then the high level of the ¥ will be turned on.

306 is fed into the gate of transistor 307, turning 307 on, and the comparison line m is pulled low. That is, when the data stored in the first node AB does not match the B, the m line of the comparison line is pulled low; when the comparison matches, the level is kept high. If each memory cell of the same word line matches, the m line of the comparison line can be kept at a high level.

The AB bit line is the address data line, the Β bit line is the corresponding instruction bit line, W is the word line write line, m is the comparison line, and R is the current limiting resistor. As shown in FIG. 5, FIG. 5 is a circuit diagram of a column write mode for a content addressable memory device in a content addressable light control switch device according to the present invention. Since in the content addressable light control switch device 39, the address-related memory cells have the same data for the same column, the word line can be omitted, and the address data to be stored is directly written by the bit line to Memory unit _C.

In FIG. 5, 308 is a D-type latch, and the logic level of the input terminal D is determined by the opening and closing of the address setting switch SA. When the power is turned on, the level of the capacitor K is gradually increased, and the single trigger is activated. The pulses generated by the steady state oscillators 309, 309 lock the SA set logic data D into the latch 308, and the address memory cells in the same column are also set. The push button switch 310 is used to activate the 309 update setting when some need to manually test or change the address.

The memory unit has two nodes, the input of the first node 303 is for storing data, and the output of the second node 303 is The end is the complementary data that stores the data.

The first node is connected to the gate of the first comparison transistor 306, the second node is connected to the gate of the second comparison transistor 305, and the first node is simultaneously connected to the corresponding address bit D-type latch via the first bit line AB At the output end of the 308, the second node is simultaneously connected to the complementary output terminal of the corresponding address bit D-type latch via the second bit line, and the input terminal of the address bit D-type latch is set by the address setting device. Logical value. The first bit line AB and the second bit line are write lines of the same address bit of each address related instruction, and the source of the second comparison transistor 305 is connected to the output corresponding to the input instruction shift register via the instruction data line B. The source of the first comparison transistor is connected to the complement of the bit output corresponding to the input instruction shift register via the instruction data complement line B, and the drains of the first comparison transistor 306 and the second comparison transistor 305 Connected to a gate of a comparison line driving transistor 307, the drain line m drives the drain of the transistor 307 to be logically grounded, and the source of the comparison line driving transistor 307 is connected to the comparison line, and the comparison line is limited. The current device R is connected to a logic high potential, and the source of each of the comparison line driving transistors of the same command line is connected to the peer comparison line.

The content addressable address-related memory unit in the memory device, the same bit address memory unit is connected to the corresponding address bit D-type latch via the address write line, and the shared D-type latch is memory, and The memory unit for each address bit is simplified and cancelled. As shown in FIG. 6, FIG. 6 is a simplified circuit diagram of a column write mode employed by the content addressable memory device in the content addressable light control switch device of the present invention. Since the address data has been saved by the latch 308, the memory cells 303, 304 can be omitted in practice. Compared with the circuit of Fig. 4 which is similar to the random access memory, the circuit shown in Fig. 6 is simplified, so that the overall content addressable light control switch device 39 is further streamlined in the process and layout, which is advantageous for reducing the manufacturing cost. As shown in FIG. 7, FIG. 7 is a block diagram of a light scene setting device in a lamp controller provided by the present invention. Each lighting scene can have 100% (full brightness), 75%, 50%, 0% (off) four setting options, each scene has 2 digits of the dial switch as shown in Figure 7 of SS1, SS2 , SS3, SS4 are used to set the brightness of the light source in each lighting scene.

For example, when the control command is 00010001, the switch control signal m2 of the light scene 1 is at a high level, and the remaining m0, ml, m3, m4, m5, m6, m7, m8, m9 are all low level, and the m2 is high level. The selection circuit 401 is in the execution function state, and the low level of m3, m4, m5 causes the remaining selection circuits 402, 403, and 404 to be in the removal function state. When the SS11 and SS12 are closed in the light scene setting switch SS1, Loss of the door 401-1 The output is high, and the other outputs 401-2, 401-3, 401-4 are low. The high level of 401-1 enters OR gate 406-1 and is locked into parallel input parallel. In the output bidirectional shift register 405, the output terminal Q1 of 405 is at a high level, and the light source is 100% fully illuminated.

If SS11 is closed and SS12 is open, the output of AND gate 401-2 is high. This high level inputs OR gate 406-2 and inputs D2 of 405, causing source 35 to be 75% bright. The rest of the brightness selection and so on. The m8, πι9 level shifts the shift register 405 up or down, causing the output terminals Ql, Q2, Q3, Q4 of 405 to move up or down, thereby dimming or dimming the source 35.

M6 and m7 jointly control the switching of the light source with m0, ml via OR gates 407, 408, respectively. Either m0 or m6 can turn on the light source 35, ml, m7 can turn off the light source 35. Figure 7 shows only the function description of a 4-segment dimming lighting scene setting device that can be used. Others such as 2-stage dimming and 16-segment dimming are also available, depending on actual needs.

The lighting scene control command m2-m5 is passed through the OR gate 409 and the dimming command m8, and the dimming command m9 is entered into the decoding circuit 410 to control the operation mode of the bidirectional shift register 405. The register 405 can be an integrated circuit similar to 74F194. When any of m2, m3, m4, m5 is high level, 405 is a parallel input mode, and when tn8 is high level, it is an up shift mode, and when m9 is a high level, it is a direction. In the lower shift mode, the 405 can be wired as a ring shift. The above embodiments are merely illustrative of one way to independently control a single lamp. Due to the need for independently controlled luminaires, which are usually special luminaires, require finer dimming capabilities, such as 16th order dimming. This dimming technique is not difficult to achieve in the lighting process. For example, the DALI system regulates the use of wavelength-width modulation (PWM) to achieve 256-step dimming. Applying this more sophisticated dimming technology to the lighting scene setting device and the light source driver, the fine dimming requirements can be achieved. This kind of simple lighting control for general luminaires, finer dimming of special luminaires, the price of the overall lighting system can be well controlled, no waste of quality and no waste, and no reduction The quality of the lighting of the special lights. It provides a simple and compatible way to maximize economic benefits. The above described specific embodiments of the present invention are described in detail, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
