Description

Energy-saving lighting scene synchronization controller

The invention relates to the technical field of electric illumination zone control, in particular to an energy-saving lighting scene synchronization controller applied to a digital electric lighting zone control system. The energy-saving lighting scene synchronization controller cooperates with the environmental state sensing device to activate the energy-saving lighting scene to achieve energy-saving purposes. When resetting and restoring, the original lighting scene is restored to maintain the consistency of the overall lighting scene. 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.

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 applied to 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 lighting scene controllers generally have 4 to 8 scene keys to choose from.

In addition to pure lighting functions in daily life, in many places, it is often necessary to set multiple lighting scenes to meet 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. Commodity exhibition space, the show's theme should focus a little light, dark background surrounding it is desirable that, in order to create contrast, highlighting the theme; ^in; when do cleaning work should be full brightness. When 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, but the projection screen should be completely dark near the stage, 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, - to reduce unnecessary electrical lighting energy waste in empty rooms, or to use daylighting, you must rely on electric lighting automatic control system. Whether the electric lighting automatic control system can be popularized is actually a problem closely related to saving electric lighting energy. 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, China Patent Application No. 200610111784.0, is entitled: A patent application for the lamp control function unit of the electric lighting zone control system, and proposes a solution to the technical solution, which has improved in terms of lowering the price and improving the convenience, but The Chinese application No. 200610111784.0 patent application, in the field of energy-saving lighting automation control, did not propose a supporting scheme.

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 sensor automatic controller to automatically turn off the lights when there is enough reference.

The automatic light switch is a simple problem, but the electric lighting control system that controls the overall lighting scene is not so straightforward. First of all, the grouping and setting work is inevitably 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 will be further described in detail below with reference to the specific embodiments and with reference to the accompanying drawings.

As shown in Fig. 1, Fig. 1 is a schematic diagram of a lighting arrangement of an electric lighting partition lighting scene control system with a lighting window office. Figure 1 also represents a schematic layout of a school classroom or other venue lighting fixture with a daylighting window. In Figure 1, the power line 'I supplies the mains, the two-phase digital bus 2 transmits the control command, the total lighting controller SC controls the office lighting scene, and the basic lighting control function unit 3 through the electric lighting partition control system controls the lighting .

Offices with lighting windows 10, In order to use sunlight to achieve energy-saving purposes, as shown in Figure 1, the lamps 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 and contains 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; Off, all the fixtures in the office fall into the fourth group 14, including all the fixtures.

Office 10 total lighting controller SC, with four scene selection buttons and total opening key, as long as the scene selection button is pressed, the entire office lighting will be in place once. The total lighting controller SC supplies two-phase digital bus 2 DC power. The office is a lighting control area, each row of lamps is a lighting control group, the office total lighting controller SC, with a total key and four light scene selection keys. The four lighting scenes are: lighting scene one, all lights are one-third bright; lighting scene two, all lamps are two-thirds bright; lighting scene three, all lamps are all bright; lights scene four, all lamps are off.

Basically, the control of the lighting scene is achieved by changing 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 ordinary four-segment lighting scene can be achieved by using ordinary fluorescent tubes. The lighting scene is one, each light box is bright with a light tube; the light scene is two, each light box is bright with two lights and tubes; the light scene is three, each light box is bright with three tubes Light scene 4, all the light boxes are turned off.

Grouping the lamps is for the convenience of setting the lighting scene and executing instructions. Setting the lighting scene is convenient for lighting control. If the lighting scene setting work of each luminaire can be easily performed, each luminaire can easily receive and execute the lighting scene command directly, then grouping is not necessary, thus eliminating many restrictions, the above lighting scene setting work, It is easy to use the electric lighting partition control system of Chinese Patent Application No. 200610111784.0.

In order to utilize daylighting, the most straightforward approach is to install a daylight sensor controller (not shown) for each row of lamps, and issue control commands based on the daylight. For example, the first row of lamp daylight sensing controllers, when the measured daylight illuminance exceeds the fixed value, issue an energy-saving turn-off light control command to turn off the first row of lamps, that is, turn off the first group of lamps 11-1, 11- 2, 11-3. The second row of lamps 12 is the same as the third row of lamps 13 . Between each row of lamps, or between each row of lamps and the office 10 total lighting controller SC, separated by a picture relay DR (not shown). The picture boundary repeater is a functional unit of the Chinese patent application number 200610111784.0 electric lighting partition control system. The double-byte full-area system command can freely pass through the picture boundary repeater, and the single-byte interval command cannot pass 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 an empty room energy-saving controller. The lights are automatically turned off when the room is in use. Empty room energy-saving lighting scene synchronization controller VS, should be set in the office 10 total lighting controller SC The same level of digital bus section, so that the empty room energy-saving controller system energy-saving control instructions, can reach all the lamps.

When there is no staff activity in the office, the empty room energy-saving lighting scene synchronization controller VS, automatic energy-saving shuts down all the lights in the office. Generally speaking, because the office is a public place, it is not advisable to change the lights frequently. When the lights are turned off due to energy saving, and the lighting is restored, it is better to return to the original lighting scene. In order to achieve the above objectives, the empty room energy-saving lighting scene synchronization controller VS, must simultaneously register the lighting scene control command, in order to restore the lighting, return to the original lighting scene.

One purpose of the energy-saving lighting scene synchronization controller of the present invention is to synchronously register the lighting scene control command at any time, so as to turn off the light after the lighting is turned off due to energy saving reasons, and then return to the original lighting scene to maintain the overall lighting. The consistency of the scene.

Electric lighting energy saving can also directly achieve the energy saving purpose by changing the lighting scene, and switch to a lighter lighting scene when the sunshine is strong. For example, Figure 1 has an electric lighting partition lighting scene control system for the Twilight Window Office. Set four lighting scenes: Light scene one, all lamps are one-third bright; Light scene two, all lamps are two-thirds bright; Light scene three, all lamps are all bright; Light scene four, all lamps are off. Automatically switch the lighting scene with the intensity of the sun. This kind of energy-saving design that automatically switches the lighting scene with the intensity of sunshine is more suitable for places where there is more rainy weather and less sunshine.

Another purpose of the energy-saving lighting scene synchronization controller of the present invention is to use the daylight sensing controller SLS in Fig. 1 to automatically switch the lighting scene according to the strength of the light, so as to achieve energy saving by directly changing the lighting scene.

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 is easy to adjust at any time. The decoding device 33, after decoding 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.

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 a switching signal to the decoding means 33 via the latch 43.

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

The clock management device 40 generates a pulse L for locking m0-m5 into D0-D5 after the information processing device 41 detects the stop bit. The LC is a latched pulse L controller that performs latching only if the m0-m5 match line has one and only one match.
