Description

TECHNICAL FIELD

[0002] With the development of economy, people's living standards have improved significantly, and the requirements for lighting effects are getting higher and higher, so the lighting energy consumption is increasing year by year. In public buildings such as office buildings and commercial office buildings, the lighting energy consumption accounts for 20%-40% of the total energy consumption, and a considerable part of it is "ineffective lighting", which causes huge resource waste. The existing lighting energy-saving control scheme usually reduces the working time of the lighting device in a fixed time period or reduces the number of lighting devices in use by a fixed number, which is not intelligent enough and has poor energy-saving effect. In addition, although the existing lighting energy-saving control scheme can reduce the power consumption to a certain extent, in the peak power consumption period, the huge power consumption in public buildings will still put great pressure on the power grid.

[0031] Embodiment 1

[0032] The present embodiment provides a building intelligent auxiliary lighting energy-saving control system, as shown in the figure, the system comprises: Figure 1

[0033] A plurality of lighting devices 1, the present embodiment uses a semiconductor lamp (such as LED) with high luminous efficiency.

[0034] New energy power generation device 8 for converting other forms of energy into electrical energy, the new energy power generation device 8 includes photovoltaic power generation device and wind power generation device; the storage device 2 is used for storing the electrical energy converted and obtained by the new energy power generation device 8; wherein the photovoltaic power generation device includes photovoltaic cell panel (assembly), controller and inverter, the photovoltaic cell panel converts sunlight directly into direct current and stores into the storage device 2 (battery), when needed, the controller adjusts the current and voltage, the inverter converts the direct current into alternating current for the building lighting device 1; the wind power generation device includes wind turbine, rectifier charger and inverter, etc., the wind turbine is composed of wind wheel (blade), machine head (including rotor and stator), rotating body and tail wing, the wind wheel captures wind power and converts it into mechanical energy, the rotor in the machine head cuts the magnetic force line by rotating, and the induced electromotive force is generated in the stator. The output electrical energy of the wind turbine is variable AC, which usually needs to be rectified by the rectifier charger to charge the storage device 2, and when needed, the direct current is converted into alternating current by the inverter for the building lighting device 1.

[0035] The control device 3 is used for controlling the lighting device 1 in the public area of the building according to the first control strategy and for controlling the lighting device 1 in the non-public area of the building according to the second control strategy; when the storage capacity in the storage device 2 is greater than a preset proportion (for example, 70%) and the power generation efficiency of the new energy power generation device 8 is greater than a preset value, the storage device 2 is called to supply power to the lighting device 1, otherwise the mains is called to supply power to the lighting device 1.

[0036] ​In the above scheme, by introducing the power storage device 2, the power supply pressure of the power grid can be alleviated, the consumption of coal can be reduced, and energy saving and emission reduction can be realized; at the same time, since the power generation law of the new energy power generation device 8 has a certain randomness (the intensity of sunlight or the size of wind will affect the power conversion efficiency), in the efficient power generation period of the new energy power generation device 8, the part of the power is consumed in time, the conversion efficiency of the new energy power conversion can be improved, and the resource utilization rate can be improved. In addition, in the embodiment, different control strategies are adopted for different regions, which can meet the power demand of users in different occasions, and can maximize the guarantee of the lighting comfort requirement of users on the premise of realizing the energy saving target, and realizes the intelligent and humanized regulation and control of the lighting device 1.

[0037] Embodiment 2

[0038] Specifically, the public area in embodiment 1 can be a staircase, a corridor or a public toilet; the system further comprises: a first illuminance measuring device 4 for measuring the illuminance of the public area (or the average illuminance in the area); a positioning system 5 for obtaining real-time position information of the personnel in the building; the control device 3 further comprises: a first control unit 31 for executing a first control strategy, the first control strategy comprising (as shown in the figure): Figure 2

[0039] During the working time period, when the natural illuminance of the preset target area is not lower than the first expected illuminance, the lighting device 1 in the target area is turned off; when the natural illuminance of the preset target area is lower than the first expected illuminance, the illuminance of the target area is compensated to the first expected illuminance by adjusting the power of the lighting device 1 in the target area.

[0040] During the non-working time period, whether a person enters the target area is judged according to the real-time position information, if yes, the lighting device 1 in the target area is turned on, and the power of the lighting device 1 is adjusted to make the illuminance of the target area meet the first expected illuminance; otherwise, the lighting device 1 in the target area is turned off.

[0041] The working time period is mainly in the daytime, the time period when most of the staff in the office building work, for example, 8:00-19:00 (adjustable adaptively for different time zones), during which period, there are more people in the public area of the office building and the activity range is wider, so it is necessary to ensure that the light in most of the activity areas with more personnel flow is sufficient to avoid safety hazards caused by insufficient light. During the day, the sunlight is usually sufficient, so it is only necessary to supplement the lighting in the area with relatively dark light (natural illuminance lower than the first expected illuminance), so that the total energy consumption of the lighting device 1 can be reduced and the lighting demand of the user can be met, wherein the value of the first expected degree can be 100lx-300lx.

[0042] ​In the non-working time period, for example, 19:00-8:00, the natural light is dim, and there are fewer people in the office building, and people in the public area are not many, so the position of the people in the building can be determined, and the lighting can be targeted. In general, people in the building do not stay in the public area for a long time, so in the case of dim light and few people, only the lighting on the route and the destination needs to be ensured.

[0043] Preferably, the system further comprises a positioning system 5 for obtaining real-time position information of the people in the building; a path prediction module 6 for predicting the moving path and destination of the people in the building according to the real-time position information and the building map; and the first control strategy further comprises: in the non-working time period, the lighting devices 1 on the predicted moving path and the predicted destination of the people in the building are turned on in advance. In this way, the delay in turning on the lighting devices 1 can be avoided, and the lighting devices 1 are turned on when the people in the building are close, which can easily cause fear in the dark environment. The path prediction module 6 is a well-trained machine model, and in general, employees have fixed moving routes in the office building, including routes to the office and routes to the toilet, so it is easy to infer the moving path and destination of the people in the building when their identities are determined.

[0044] The scheme provided by the embodiment can effectively meet the light emission requirements of the lighting devices 1 in the public area at different time periods, and can reduce the energy consumption of the lighting devices 1 to different degrees in the two time periods, and realize intelligent and humanized control.

[0045] Embodiment 3

[0046] This embodiment mainly illustrates the lighting control strategy for non-public areas, and takes a representative conference room as an example. The conference room usually has a projector, and the user needs to keep the light relatively dark when using the projector in the office to ensure clear projection, but the light cannot be too dark, otherwise it can easily hurt the eyes and cause eye fatigue. In this embodiment, the working mode of each lighting device 1 in the conference room in the viewing state is set to the viewing lighting mode. To provide more humanized lighting service, it is also necessary to detect the environmental conditions and the position state of the people in the conference room in time to quickly respond to the needs of the user, so the energy-saving control system further comprises: a people detection device 9 arranged in the conference room, for detecting the number and position of the people in the conference room; and a second illuminance measuring device 7 for measuring the illuminance of the conference room; and the control device 3 further comprises a second control unit 32 for executing a second control strategy, the second control strategy comprising (for example Figure 3If the number of people in the conference room is zero or the natural light illuminance in the conference room is not lower than the second expected illuminance, all the lighting devices 1 in the conference room are turned off; otherwise (i.e. the number of people in the conference room is not zero and the natural light illuminance in the conference room is lower than the second expected illuminance), it is determined whether the projector is in an enabled state; if yes, the lighting devices 1 in the conference room are controlled according to a viewing lighting mode. Specifically, the viewing lighting mode is that the lighting devices 1 close to the screen are turned off, and the illuminance of the area far from the screen is adjusted to an optimal viewing illuminance (30 lx-100 lx, depending on the brightness of the screen).

[0047] If no (the projector is in a disabled state), it is determined whether the people in the conference room are dispersed according to the positions of the people in the conference room; if yes, all the lighting devices 1 in the conference room are turned on, and the illuminance in the conference room is compensated to the second expected illuminance by adjusting the power of the lighting devices 1; if no, only the lighting devices 1 near the place where the people concentrate are turned on, and the illuminance at the place where the people concentrate is compensated to the second expected illuminance by adjusting the power of the lighting devices 1, with the minimum total energy consumption of the lighting devices 1 as the goal. When a large number of people enter the conference room and are dispersed, it is indicated that the user may hold a large-scale meeting or activity in the conference room, and therefore the illuminance in the entire conference room needs to be ensured to be not lower than the second expected illuminance (300 lx-500 lx). If the people entering the conference room concentrate in a place, it is indicated that a small number of people gather together to hold a small-scale meeting, and therefore the lighting in the rest of the conference room is "ineffective lighting" for a large conference room, and thus turning off the lighting devices 1 far from the place where the people concentrate can reduce the energy consumption and achieve energy saving.

[0048] Exemplarily, the above-mentioned personnel detection device 9 can adopt a CMOS image sensor and at least three infrared ranging sensors not arranged on the same straight line. The CMOS image sensor has the function of measuring the illuminance distribution, and thus can replace the second illuminance measuring device 7. The CMOS image sensor measures the large illuminance distribution in the conference room, and can complete accurate measurement of the illuminance distribution through image acquisition and image processing, and can also realize detection of the environmental color temperature, the personnel density and the personnel behavior. However, the CMOS image sensor can also have a blind area or be blocked, and thus at least three infrared ranging sensors not arranged on the same straight line can also be arranged in the office to calculate the specific positions of the people in the room based on an RSSI positioning algorithm.

[0049] Exemplarily, if there are n lighting devices 1 near the place where the people concentrate, and the n lighting devices 1 have the same specification parameters and the same rated power P R , the illuminance E A at the place where the people concentrate can be represented as:

[0050]

[0051] In formula (1), E i represents the illuminance generated by the i th lighting device 1 at the personnel gathering place, E N represents the natural light illuminance at the personnel gathering place;

[0052] The luminous flux Φ i of the i th lighting device 1 at the personnel gathering place can be represented as:

[0053] Φ i = E i × S (2)

[0054] In formula (2), S represents the irradiation area at the personnel gathering place;

[0055] In the optical illuminance formula, since no power parameter is involved, the relationship between the luminous flux and the power is established according to the light emitting efficiency of the lighting device 1, the larger the luminous flux of the same lighting device 1, the larger the corresponding power (energy consumption), and therefore the energy consumption of the lighting device 1 is positively correlated with the luminous flux. In order to save the lighting energy consumption, the objective function with the minimum total luminous flux of the lighting device 1 as the target can be set as:

[0056]

[0057] The constraint condition is: E A ≥ e2 (4), wherein e2 represents the second expected illuminance;

[0058] The second control strategy further includes:

[0059] Solving the objective function, the power of the n lighting devices 1 is obtained respectively, and at this time, the total power consumption of the n lighting devices 1 is minimum. Exemplarily, a particle swarm optimization algorithm can be used for optimization solution.

[0060] In this embodiment, corresponding lighting control strategies are formulated according to the functions of non-public areas (conference rooms, offices, and rest rooms, etc.), which reduces the energy consumption of the lighting device 1 while realizing humanized intelligent control, automatically adjusts the working mode of the lighting device 1 according to the application scene, meets the diversified needs of users for the lighting mode, and improves the user experience.
