Intelligent lighting control system is to provide various types of buildings with high controllability and further enhance the building to green energy and levels. It is the core product of energy saving and digital technology exchange. The scale of the system is very flexible, from small to more than a dozen loops of hostless small-scale applications with thousands of loops of network-based systems can be used. This is because lighting in modern buildings and residences not only provides good visual conditions for people's work, study, and life, but also uses modeling light colors to create an interior environment with a certain sense of beauty.
So the intelligent lighting control system came into being. With the implementation of the green lighting project plan, the intelligent regulation of the semiconductor scene lighting system has gradually developed. In particular, a new generation of digital lighting control system that is practical and easy to use can be used to construct various types of new solutions in the home or office and in commercial or public spaces with various types of building features. For this reason, this paper will discuss the architecture and application modules and features of the intelligent lighting control system, and will focus on the analysis of the implementation of the 'wisdom' technology of the lighting control system, and control the intelligent lighting in the home office and commercial buildings. Application in space.
Based on this, we first discuss the architecture of a smart lighting control system. Figure 1 shows a block diagram of a smart lighting control system. It is a high-tech control system that uses a D-bus (a pair of data communication 2C communication lines) to run through the entire building, high-tech digital switches installed at different locations, or various traditional switches of various exquisite styles. The user can control the control output device in other locations at any location. Start or stop the scene atmosphere control. The user can also control the way to the mobile Internet via a colorful touch screen on the wall. For all types of buildings, the system can also be integrated with various central monitoring systems.
1 Application features and module application of intelligent lighting control system
From the schematic block diagram of the intelligent lighting control system in Figure 1, we can see that the entire lighting control system is organically connected to each component through the D-bus bus. Its application features are as follows:
* Infrared control modules should be used with infrared sensors, which are normally open or normally closed during the day and controlled by infrared light at night. Which is applied it is a new type of infrared chain control, this is often used in walkways or toilets between tea stations, with power-saving control, its function must be matched with infrared control module. It can be set as one of the following two modes: Normally, it is on state. When the close command is issued, it will follow the infrared action delay; or it will be normally off. When the open command is issued, the infrared action delay will be followed.
* The simple type touch switch is a color touch screen operation. It is used in conjunction with a communication transfer converter and should be synchronized with the field circuit status. The same system can be installed with multiple touch screens. It should be noted that the mobile phone can also be a remote controller. When you are away from home, you can use the mobile phone screen to grasp the light switch status of your home or turn on the pre-lighting or the lighting inside the house before going home.
* Power equipment control This function needs to cooperate with the electromagnetic switch control module. Note that electromagnetic switches are mostly used for higher power motor equipment or air conditioners or high power lamp groups. The system can not only control the lighting, as well as empty, smoke, or smoke, but also its blower can be controlled together. The four-loop addressing power control electric module can control and monitor four groups of external electromagnetic switches, and is a code setting, including four groups of 10A electric modules, containing 12 groups of state contact inputs, for the digital interface, 2-wire type Communication.
* Time-course control and web-based time-course controllers are on the bus, and can be adjusted on the Internet in a timetable or forced switch. Modify the schedule and remote control through the Internet. The control method adopts group as the unit, and does not use individual loops as the unit. It can control up to 10 groups. The web-based time-course controller function is: can be connected through the web page to schedule time (in weeks); it can use two kinds of timetables for different time schedules per week; can also control the group of 12 groups , control the entire district multi-zone loop, and through the web page for remote monitoring and adjustment settings and remote control of a group; but also independent operation, without relying on computers and the Internet.
* The remote control operates in the living room or home theater, holding a remote control to operate all facilities. Contains AV, audio, DVD, curtains, projectors, lighting and air conditioning, where lighting is the most important equipment in the space atmosphere, click [watch], [break], [party], [quiet], [ Enthusiastic], [warm] and so on, to create a completely different Fengfeng sense of space.
* With the traditional switch traditional switch shape and material selection Hui multiple, easy to meet the decoration design needs. The traditional switch facilitates more maintenance in the future; the matching circuit is similar to the traditional operation. In the vicinity of the circuit where the lights are located, traditional switches can be used together with four-circuit traditional switch addressing templates or three-circuit switching system interface units. Traditional switches can still be set for group control or scenarios.
* Dimming control This function needs to be combined with the dimming application module. When the knob is manually adjusted, the lamp follows the knob for dimming, depending on the scene command when scene commands are frequently used. The dimming application module output is 0-10V high and requires an additional dimming type electronic ballast or thyristor. The dimming application module is used in conjunction with energy-saving applications or meeting room and living room atmosphere; its address can be set to 1-64, there are 8 sets of scene settings, and 4 sets of DCO~10V output connect dimming ballast or can be Silicon control, working voltage is AC18V/DC24V, 4 sets of O-10vdc input terminals connect with local control buttons, digital interface, 2-wire communication, dimming application module rated capacity is 300VAC/20A.
* Daylight-saving energy-saving control applications: When the outdoor lighting is strong, the light circuit near the window or roof can automatically adjust the darkness and adjust the outdoor light intensity according to the timetable. Should be used in conjunction with a temperature control switch. When the temperature control switch function exceeds a certain temperature, a special group opening or group closing command can be issued through the D-bus bus to control the power supply of the air conditioner. The most effective method is the air conditioner energy saving management, which includes a temperature sensor and a control power supply. 8A/220VAC.
* Air conditioning temperature saving control is also used in conjunction with the temperature control switch. It starts to supply above 27°C. If the temperature is 23°C, the temperature is too low and the power is off. The normal operating range is between 23°C and 27°C. Energy-saving application: When the outdoor temperature reaches 27°C or above, the air-conditioning power supply in the area is opened, and when the outdoor temperature is lower than 24°C, the air-conditioning power supply is suspended.
* The integrated control of the central control system should be used in conjunction with the communication converter. The system provides a communication open protocol (MODbus) for the integration of various types of building automation systems, which can synchronously respond to the current status of the main system and receive system control commands. Its communication converter can provide RS485~RS232 conversion function, maximum 16-node LT addressing (64 loops), D-BUS gateway with RS485 or RS232 interface, and communication speed of 9600 baud.
* Multiple operations throughout the system allow manipulation of designated circuit lanes in multiple locations. On the digital switch or on the touch screen, the on/off status of the corresponding circuit can be displayed synchronously. Press once to open and press again to close.
* The scene control decides whether to turn on or off the specified loop, or to reserve the dimming degree to create a space atmosphere. Press once for members of the same group to open, some for close, and some will adjust intensity.
* The group control operation uses the same open and close operation. For example, when you go to work, press the work button to turn on all the office and lobby lighting. When you are off work, you can press the shift button to switch.
The LT4500 output is 0-10V high and requires an additional dimming type electronic stabilizer or thyristor. The sub-circuits are combined into a group by the setting method, and the circuits of the same group are all turned on and off together.
Intelligent lighting control system In addition to the above application features and modules, there are plane lighting monitoring software, dedicated timers, transformers, and 16-channel flexible lighting controllers.
2Implementation of 'smart' technology for intelligent lighting control systems
Today's DSPs, 16-bit monolithic microcontrollers and other chips are all effective choices to achieve the 'smart' technology core. However, from the perspective of cost-effectiveness, the Spartan-4 FPGA chip is ideal as the core technology choice for smart technology. . Why is this wrong? Since a field programmable gate array (FPGA) is an embedded IC, a matrix can be configured using a computing element and a software design can be performed using hardware logic. Unlike fixed computing functions of traditional microprocessors and DSPs, FPGA devices rearrange internal structures to perform computational tasks. The FPGA is completely parallel in design, so many application subsystems can use dedicated hardware resources and operate independently and synchronously.
In an FPGA fabric, an implementation method that translates software code into highly optimized hardware is called synthesis. Because there may be multiple hardware implementation methods to meet the requirements, the FPGA compiler can perform complex optimization, path selection, and validation. The design uses the form of information flow. The main chip of the LED lighting control system adopts the Spartan-4 FPGA chip, which has abundant memory resources and hardware multiplier resources for real-time data operations. These logic resources provide a sufficient hardware basis for complex situational lighting control and intelligent control strategies. At the same time, the FPGA performance is stable and there is almost no chance of crashes. Figure 2 shows the application of the Spartan-4 FPGA chip in a smart LED lighting system.
The LCD panel in FIG. 2 provides interactive information display for the user. According to different design requirements, the control parameters may be input by using a key input or a touch screen. Profile data is stored in Flash, and can be queried and modified by desktop or notebook software via the USB-RS232 interface to facilitate online upgrade of system features. The RAM memory selects SRAM or SDRAM according to actual demand, mainly used for temporary data storage for complex operations, or as an external memory necessary for realizing the embedded processor NIOSII in the FPGA.
* The I/O expansion in the control system is mainly used to implement the infrared remote control function and the wired remote control panel function. When the room is large and large, it is necessary to extend some of the control panels to facilitate the use; in the occasion with higher requirements, infrared remote control can also be used to distribute the infrared receiving probe to all the areas to be controlled. Easy to control scene lighting.
Utilizing the rich logic resources of the FPGA, the complexity of the peripheral circuit design can be reduced, and the digital signal processing can improve the reliability and enhance the degree of intelligence. In the control box, parameter controls such as color temperature, brightness, blinking, dizzy mode, children's room and mood can be integrated, and the conditions for triggering these scene lighting modes can be independently set. Using the desktop or laptop software, not only all of the controls can be controlled The lamp cap can record all the operating state parameters of the lamp head. According to the attenuation rule of the LED parameters provided by the manufacturer, the LED driving parameters can be automatically modified at an appropriate time so that the illumination characteristic attenuation can be compensated.

For example, the lighting of the living room or room can be switched on and off by pressing a button in the parking area before going out. When you go home, the lighting along the road can be switched on with a touch of a button, as shown in Figure 2(a). Clever use of lighting features in design can enable the same space to exhibit a completely different spatial tone; making home life more vibrant and lively, as shown in Figure 2(b); touch the bedside button in the bedroom If you want to read or appreciate the desired situation lighting combination, just touch the bedside button before going to sleep, you can turn off the various lighting of the living room and walkway or garden, do not have to get up and turn off the lights so that the destruction is not easy to cultivate good drowsiness Plan the required situational patterns in advance, and touch the color touch screen to make guests or party or appreciate the choices of different situations such as festivals or reading books, as shown in Figure 2(c).
3.2 New Requirements for Public Space
Corporate office buildings, libraries, station airports, government buildings, stadiums, campuses, art galleries, training centers, parking lot exhibition centers, etc. occupy a wide area. Due to their multiple spatial characteristics, lighting and air-conditioning facilities are not easily controlled, so labor-saving measures are needed. Control management or time-course automatic control, and further with the green energy-saving appeal, to explore the appropriate energy-saving control functions.
For example, the administrator can control and control the public lighting and air-conditioning circuits in the district on the color touch screen next to the refusal of the station, and does not need to go around to show energy-saving and intelligent high-tech performance. Conference rooms or multi-function rooms can be used in conjunction with the different needs of meetings or presentations or briefings to perform lighting control of the view mode. The desired situation lighting combination can be selected by using the touch screen on the wall and the partition's digital switch; lighting during work peak hours The circuit was opened and entered the off-peak period in the evening, and it was changed to match infrared sensors. In the reception counter, or in the guard area or control room, the status of the lighting in each section can be controlled through the color touch screen. It can also be remotely controlled; and each partition can also be set to a local switch nearby. Each district circuit is equipped with cooperation needs, timely and automatically according to the preset schedule to stop the lights of the various circuits; temporary special activities, you can also use the Internet remote control or repair schedule, greatly simplifying the complexity of the control. The mobile phone can also be a remote control remotely and go out, through the mobile phone screen, you can grasp the light switch status in your home or remote control before you go home or turn on the lighting in the room.
3.3 Comfortable and convenient commercial space
Restaurants, theaters, convention centers, shopping malls, shops, hospitals, hotels or motels, entertainment and leisure areas and other buildings with a large number of floors and a wide range of space require labor-saving maneuver management or automatic time-course control, and they also need to meet the needs of business travelers. Perform situational lighting control. In the hotel rooms, touch the bedside button switch to change the lighting situation in the room. Such as warm, television appreciation, good night, etc., as shown in Figure 3.
