Description

Electric lighting energy-saving lamp controller device

Technical field

The invention relates to the technical field of electric lighting zone control, in particular to an electric lighting energy-saving lamp controller device (hereinafter referred to as: energy-saving lamp controller). The energy-saving lamp controller cooperates with the environmental state sensing device energy-saving switch device (hereinafter referred to as: energy-saving switch device), accepts the energy-saving switch command issued by the energy-saving switch device, and starts the energy-saving switch-off light to achieve the purpose of energy saving, and the energy-saving switch off the light. When the cause is eliminated, the restoration of the lighting is reset, and the previously latched lighting scene is restored to maintain the consistency of the overall lighting scene before and after the energy saving off and resetting and restoring the lighting. Background technique

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

The Digital Addressable Light Interface (DALI) system was developed successfully in Europe and is gradually accepted by the world. The architecture consists essentially of a bus power supply, at least one controller, and a luminaire with a digitally addressable light interface receiver. Each digital addressable light loop can control up to 64 individual fixtures, 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 be set up to 16 groups (0~15), and 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.

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 lights The light scene controller typically has 4 to 8 scene keys to choose from.

In addition to the simple lighting function in daily life, it is often necessary to set multiple lighting scenes in many places to meet the actual needs. These needs are sometimes functional, sometimes for energy savings, and sometimes for both.

For example: General halls and walkways, should be fully bright when cleaning work, usually half bright. For the merchandise display space, the key theme of the display should be brighter, and the surrounding of the background should be darker to create contrast and highlight the theme; but when doing cleaning work, it should be fully lit. When there is a meeting in the conference room, the lighting on the conference table should be brighter, and the surrounding area should be darker. When making a briefing, the whole room should be darker. Only the projection screen near the desk should be dark, so as to project the image. 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 (DALI) lighting control system is used, the lamps must be grouped first, and each group of lights should be adjusted to the required brightness, then the groups of each group, The brightness and other data are stored in the light scene controller, and the light scene controller recalls the set light scene according to the button. The Digital Addressable Light Interface (DALI) lighting control system, although it can directly control each luminaire, is impractical and inconvenient for the average user. It is necessary to use the light scene controller or group controller to perform the actual lighting. control.

Basically, the control of the lighting scene is achieved by changing the brightness of the light source of each luminaire. The luminaires are grouped for convenience in setting and executing instructions. If the lighting scene setting work of each luminaire can be easily performed, and each luminaire can easily receive and execute the lighting scene command directly, grouping is not necessary, and many restrictions can be dispensed with.

The addressability of the Digital Addressable Light Interface (DALI) system 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 sometimes be very complicated and require professional and specialized tools to complete. This kind of professional and complicated setting work needs to rely on professional technicians to form an obstacle to the lighting system to penetrate the people's homes and urban and rural corners.

In addition, 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. For developing countries that need automated lighting control technology to address energy efficiency issues, prices are unacceptable. Therefore, an electric lighting control system that is more economical and easier to use is highly anticipated.

In particular, with the increasing energy problems, the problem of saving lighting energy has become increasingly prominent. Many countries have mandated the installation of personnel activity sensing controllers to automatically turn off the lights when there is no personnel activity. In addition, the use of daylighting is also becoming a trend, and in many countries it can be rewarded. Whether it is to save lighting energy, Reducing unnecessary electrical lighting energy waste in empty rooms, or in order to utilize daylighting, must rely on electric lighting automatic control systems. Whether the electric lighting automatic control system can be popularized is actually a problem closely related to saving electric lighting energy. The functionality, price and convenience of the digital electric lighting automatic control system are all important factors that determine whether the digital electric lighting automatic control system can be popularized.

In order to cope with the Digital Addressable Light Interface (DALI) lighting control system, the initial setting of grouping, setting the scene, setting the brightness, sometimes it is very complicated, and it is necessary to rely on professionals and special tools to complete the problem and the system price is too The high problem, Chinese Patent Application No. 200610111784.0, is entitled: A patent application for a lighting control function unit for an electric lighting zone control system, and a solution to the technical solution is proposed. The solution has been improved in terms of lowering the price and improving convenience. However, the patent application No. 200610111784.0 of the Chinese application number does not propose a matching solution in the field of energy-saving lighting automation control.

In general, in order to save electric lighting energy and comply with the mandatory norms of many countries or regions, in the empty room without personnel activities, the lights should be automatically turned off, the lights are automatically turned off, and the human activity sensor light automatic controller must be provided. In order to use daylighting and save energy, it is necessary to install a daylight sensing automatic controller to automatically turn off the lights when there is enough control. Automatically turn off the lights, you need to install a daylight sensor automatic controller.

The automatic light switch is a simple problem, but it is not straightforward for the electric lighting control system that controls the overall lighting scene. First of all, the grouping and setting work is bound to be much more complicated. Secondly, when the lighting is turned off due to energy saving, and the lighting is restored, it should be returned to that lighting scene, which is also a problem. In general, the lighting should not be changed, especially in public spaces. When lighting is turned off due to energy saving, and then the lighting is restored, returning to the original lighting scene may be the best choice. Summary of the invention

In order to make the objects, technical solutions and advantages of the present invention more clear, the technical solutions provided by the present invention are further described in detail below with reference to the specific embodiments and with reference to the accompanying drawings, from the basic lamp controller provided by Chinese Patent Application No. 200610111784.0. .

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a lighting layout of an electric lighting partition lighting scene control system with a twilight window office. Figure 1 is also well suited for school classrooms that typically have a twilight window. The power line 1 supplies the mains, the two-phase digital bus 2 transmits the digital control commands, and the lighting controller SC is the system controller, which is controlled by the two-phase digital bus 2 The basic type lamp controller 3 or the energy-saving type lamp controller 3' controls the lighting of the lamps.

When using a digitally addressable lighting interface (DALI) system, the office 10 with a light window can be used to save energy for the purpose of energy saving. As shown in Figure 1, the lights in the office may be divided into four groups. The most window-mounted luminaire in the office is the first row, which belongs to the first group 11, including the lamps 11-1, 11-2, 11-3; the middle row of lamps is the second row, which belongs to the second group 12, including the lamps 12 -1, 12-2, 12-3; The innermost row of lamps is the third row, which belongs to the third group 13, including lamps 13-1, 13-2, 13-3; All the luminaires in the office belong to the fourth group 14, including all luminaires.

The light controller SC of the office 10 has four scene selection buttons and a total opening key. Just press the scene button and the entire office light will be in place. The office is a lighting control area. Each row of lamps is a light control group, office lighting controller, with a total opening key and four lighting scene selection keys. The four lighting scenes are: lighting scene one, all lamps are one-third bright; lighting scene two, all lamps are two-thirds bright; lighting field scene three, all lamps are fully lit; lighting scene four, all lamps are off. These grouping and lighting scene setup work can sometimes be cumbersome and requires special tools. Technicians need special training to be competent. The Digital Addressable Light Interface (DALI) system can have sixteen groups and sixteen lighting scenes. In practice, it is often not enough.

Basically, the control of the lighting scene is achieved by dimming the brightness of the light source of each luminaire, but it can also be achieved by switching the light source of each luminaire. For example, if the luminaire is a light box composed of three fluorescent tubes, the luminaire is utilized. The ordinary fluorescent tube can achieve the above four-segment lighting scene effect, the lighting scene one, all the light boxes light a tube; the lighting scene two, all the light boxes are bright two tubes; the lighting scene three, all the light boxes are bright three tubes; the lighting scene Fourth, all light boxes are turned off. There are big differences between the two methods in the price of the ballast.

Grouping fixtures is for the convenience of setting up lighting scenes and executing commands. If the lighting scene setting work of each luminaire can be easily performed, and each luminaire can easily receive and execute the lighting scene instructions directly, grouping is not necessary, thus eliminating many restrictions. The above lighting scene setting work can be easily realized by the electric lighting partition control system of China Patent Application No. 200610111784.0.

In order to utilize daylighting, the most straightforward approach is to install a daylight sensor controller for each row of lamps, and issue control commands based on the daylight. For example, the first row of lamp daylight sensing controller Sl l, when the measured daylight illuminance exceeds the fixed value, issues an energy-saving turn-off light command, and turns off the first row of lamps, that is, the first group of lamps 11-1, 11-2 , 11-3. The daylight sensing controller Sl l, when the measured daylight illuminance is lower than the fixed value, the energy saving reason is eliminated, and the restoration lighting instruction is issued. The second row of lamps, the daylight sensor controller S12, controls the second row of lamps, and the third row of lamps, the daylight sensor controller S13, controls the third row of lamps. The daylight sensing controllers Sl1, S12, and S13 are all energy-saving switchers that automatically switch lights with daily illumination to achieve energy saving. Between each row of lamps, or each row of lamps and office lighting control Between the controllers SC, the picture boundary repeater DR is separated, so that each area can be independently controlled. The picture boundary repeater is a functional unit in the electric lighting partition control system provided by Chinese Patent Application Nos. 200610111784.0 and 200610076528.2. The double-byte system instructions are free to pass through the picture boundary repeater, and the single-byte interval instructions cannot pass through the picture boundary repeater.

In order to save electric lighting energy, many countries or regions adopt mandatory regulations. When there is no personnel activity, that is, when the office is empty, the office lights should be automatically turned off. The office must have the space as shown in Figure 1. Room energy-saving switch VS, automatically turn off the lights when empty room. The empty room energy-saving switch VS should be installed in the digital bus section of the same level of the office light controller SC, so that the system energy-saving control command of the empty room energy-saving switch can reach all the lamps in each zone through the picture-connected repeater.

In Figure 1, the two-phase lighting scene control command transmitted on the digital bus of the electric lighting zone control system enters the digital information processor of the lamp controller through the optical isolator. The digital information processor decodes the instructions for control actions. The lighting brightness dimming setting device can be set in advance or on site. The two-position dial switch can provide four setting options. The setting action is clear and direct, easy to operate, can be set during deployment, and it is easy to adjust at any time. After the decoding device decodes according to the setting of the setting device, the switch or control signal is output to the ballast or the light source driver to drive the light source. The light source driver can be a ballast, an electronic transformer, or a relay, depending on the light source and actual needs. The light source can also be an incandescent lamp, a halogen lamp, a fluorescent lamp, a energy saving lamp, a high pressure gas discharge lamp (HID), a light emitting diode (LED), or the like. The light source is not limited to a single light source.

The information processor includes an information data restoration device, a clock management device, a system instruction shift register and an interval instruction shift register, and the system instruction high byte is decoded by the high byte decoding device, and the low order byte of the system instruction and The interval instruction is decoded by the content addressable light control switching device, and the light control switch signal latch outputs a switching signal to the ballast or the light source driver device to drive the light source.

As shown in Fig. 2, Fig. 2 is a schematic diagram of a basic type lamp controller of the electric lighting zone control system disclosed in Chinese Patent Application No. 200610111784.0, which is a schematic diagram of the basic type lamp control device 3 of the electric lighting zone control system of Fig. 1. The light source 35 is a fluorescent tube, and the ballast 34 receives the control signal output from the control decoder 33 to switch or dim the light source 35. The two-phase lighting scene control command transmitted on the two-phase digital bus 2 enters the digital information processor 32 via the optical isolator 31. The digital information processor 32 decodes the instructions for control actions. 36 is a light brightness dimming setting device, such as a two-digit dial switch, which can be set in advance or on-site. The two-digit dial switch can provide four setting options. The setting action is clear and direct, easy to operate, can be set during deployment, and it is easy to adjust at any time. The decoding device 33, after being decoded according to the setting of the setting device 36, outputs a switch or control signal to the ballast or light source driver 34 to drive the light source 35.

In the information processor 32, 41 is an information data restoration device, 40 is a clock management device, and 37 and 38 are systems. The shift register of the command and the interval command, the high order byte of the system command is decoded by the decoding device 44, and the low order byte of the system command and the interval command 38 are performed by the content addressable light control command decoding device 39. After decoding, the signal is converted into a light control switch signal by a light control switch signal latch 43: m0幵 (full light), ml off, m2 light scene 1, m3 light scene 2, m4 light scene 3, m5 The light scene 4, after the light control signal passes through the light scene setting device 42, drives the light source driving device 34 to drive the light source 35.

The light scene setting means 42 can set the brightness of each light source in each light scene via the dial switch 36, and output the light control switch signal to the decoding means 33 via the light control switch signal latch 43.

The light control switch signal latch 43 includes a latch pulse controller LC and data latches D0-D5 that receive any of the inputs of the content addressable light control command decoding device 39. After the only light control switch signal, the latch is executed, and the light control switch signals m0-m5 are latched into the data latches D0-D5 corresponding to the control switch signal.

The clock management device 40, after the information processing device 41 detects the stop bit, generates a latch pulse L that locks the light control switch signals m0-m5 into the data latches D0-D5. The LC is a controller that latches the pulse L, and can only perform latching when the light control signal m0-m5 has one and only one match.

However, when the basic type lamp controller and the energy-saving switch device cooperate with the energy-saving automatic control, when the light is automatically turned off due to energy-saving reasons, and then extinguished due to energy-saving reasons, the lamp cannot be automatically restored before the switch-off. The state of the lighting scene cannot maintain the consistency of the lighting scene before and after the light is turned off. If the luminaire is automatically turned off after energy-saving reasons, when the lighting is restored, the state of the light scene before the turn-off cannot be automatically restored, and the previous lighting scene must be manually restored, which is obviously unacceptable.

In view of the above, the present invention provides an energy-saving lamp controller and an energy-saving switch device matched therewith, so as to realize the state of the light scene before the automatic recovery and extinguishing, and maintain the consistency of the lighting scene.

Compared with the basic lamp controller of FIG. 2, FIG. 4 focuses on energy-saving switch command decoding. The device 39S, and the enabling means 430 of the light control signal latch 43, omits the system command decoding means 44 of Fig. 2.

The energy-saving switch command decoding device 39S can decode the energy-saving switch command, and output the energy-saving turn-off light signal SR or the energy-saving recovery illumination signal SS. Energy-saving turn-off light signal SR or energy-saving recovery light signal SS, control Enable device 430, turn off or restore the output of light control switch signal latch 43, turn off the light or resume the light scene before turning off.

The structure of the energy-saving switch command, the energy-saving turn-off light command can be 00100000 (20h); the energy-saving recovery lighting command can be 00100001 (21h) o When the received command is not the energy-saving command, the energy-saving switch signals SR, SS are low The potential, through the inverter, enables the AND gate 432, and the latch pulse L of the latch pulse controller LC performs the latching of the light control switch signal latch 43 via the AND gate 432, in other words, the energy-saving switch signal SR, When SS has a high potential, the AND gate 432 is removed, and the light control switch signal latch 43 does not perform latching. Therefore, the energy saving command does not change the light control switch data latched by the light control signal latch 43 and does not change the lighting scene when the illumination is restored.

The energy-saving turn-off light signal SR resets the energy-saving switch signal latch 431, causing the output terminal Q of the energy-saving switch signal latch 431 to output a low potential, and closing the AND gates 435-1, 435-2, 435-3, 435- The output of 4, but the inverter between the output terminal Q of the energy-saving signal latch 431 and the OR gate 434 causes the output of the OR gate 434 to be true, that is, the energy-saving turn-off light signal SR causes the switching signal of the light to be turned off. If ml is true, the light is turned off; the energy-saving recovery illumination signal SS sets the energy-saving switch signal latch 431, and the output terminal Q of the energy-saving switch signal latch 431 outputs a high potential, and the AND gates 435-1, 435-2 are restored. , the output of 435-3, 435-4, recovers the latched data D2-D5 of the output light control switch signal latch 43, drives the light scene setting device 42, and the light scene setting device 42 drives the light source driving device 34, To drive the light source 35; when the turn-off light switch signal ml output by the content addressable light control switch device 39 is not true, the output of the energy-saving switch signal latch 431 output terminal Q, and the light is controlled by the OR gate 434.

The energy-saving lamp controller provided by the invention automatically turns off the light after energy-saving reasons, and then eliminates due to energy-saving reasons, and when the illumination is restored, the lamp automatically restores the state of the light scene before the turn-off, and maintains the lighting scene. Consistency.

When entering the office with the lighting window shown in Figure 1, first select the lighting scene with the system controller SC to turn on the light, the daylight automatic energy-saving switch Sll, S12, S13, automatically switch the light with the daylight, to achieve energy-saving purposes. The empty room automatic energy-saving switch VS, when the air is turned off in the empty room, to achieve energy-saving purposes, the main body of the solar automatic energy-saving switch S11, S12, S13 and the empty room automatic energy-saving switch VS are the energy-saving switch shown in Figure 6. 90. The basic type lamp controller 3 shown in FIG. 1 is modified by the energy-saving lamp controller 3' of the present invention. When the light is automatically turned off due to energy saving reasons, and then extinguished due to energy saving, the lamp is automatically restored and turned off when the illumination is restored. The state of the previous lighting scene ensures the consistency of the lighting scene.

When the empty room automatic energy-saving switch VS and the daylight automatic energy-saving switch are used at the same time, the empty room automatic energy-saving switch VS, when the light is turned off, the daylight automatic energy-saving switch S11, S12, S13 can continue to work, but the empty room energy-saving switch The VS is set at the level of system control, and the system energy-saving control command is issued to control the entire room. Therefore, the empty room energy-saving switch VS sends out the system energy-saving and turns off the light command to turn off the light, and the daylight automatic energy-saving switch S11, S12, and S13 cannot be restored. Illumination, the light remains off until the empty room automatic energy-saving switch VS issues an energy-saving recovery lighting command. The system energy-saving switch command and the interval energy-saving switch command jointly generate an energy-saving switch control signal, which can be achieved by a hardware logic circuit or by software. Figure 5 shows an example of a joint operation of the system energy-saving switch command and the interval energy-saving switch command. - Figure 5 is a schematic diagram showing the structure of a system energy-saving switch signal control circuit of the energy-saving lamp controller provided by the present invention. Compared with Fig. 4, the energy-saving switch command decoding device 39S adds a system energy-saving switch command decoding line, and generates a system energy-saving switch-off light signal SSR and a system energy-saving recovery light signal SSS. The system energy-saving switch signal latch 431S is used to latch the system energy-saving switch signal. System energy-saving switch signal latch 431S latch system energy-saving switch signal data; interval energy-saving switch signal latch 431 latch interval energy-saving switch signal data. The system power-saving switch signal latch 431S latch data and the interval power-saving switch signal latch 431 latch data, and the enable means 430 of the light control switch signal latch 43 is controlled by the AND gate 433. Because the system energy-saving switch command is valid for the whole area, when the system energy-saving switch, for example, the empty room automatic energy-saving switch VS issues the system energy-saving off-light command, the system energy-saving switch signal latch 431S of each lamp outputs a low potential. The forced AND gate 433 outputs a low potential, and each lamp light remains off until the system energy-saving switcher issues a system energy-saving recovery illumination command, so that the system energy-saving recovery illumination signal SSS is high. The total opening key of the lighting controller SC has a forced switching function for all the lamps, but since it is not the subject of the present invention and is an easy-to-understand technique, it will not be described in detail.
