A lighting energy-saving system and method for green buildings

Abstract

The present invention discloses a lighting energy-saving system and method for green buildings. A proximity sensor is arranged at the entrance of a corridor to sense the situation of people entering and leaving the corridor. When the proximity sensor senses that someone has passed the proximity sensor, a memory stores the time when the person has passed the proximity sensor. A human infrared switch is used to control the lighting of a lighting lamp within a set time. A controller is used to control the storage operation of the memory and to control whether the human infrared switch works. The present invention divides the time periods into high and low peaks according to the flow of people at night. Different lighting logics are used for high and low peaks, which is more energy-saving. The time period of the peak period is dynamically obtained according to the average flow of people in the last 30 days, which is more intelligent to use.

Description

Technical field:

[0002] The invention relates to a lighting energy-saving system and method for green buildings. Background technology:

[0004] Green building refers to a building that maximizes resource conservation, protects the environment, reduces pollution, provides people with healthy, suitable and efficient use space, and coexists harmoniously with nature throughout its entire life cycle. Therefore, from the definition of green building, the basic elements of green building can be summarized into five words: four savings and one environmental protection. In addition, lighting is needed in green buildings. The existing green building corridor lights generally include three control methods, one is a sound sensor, one is a touch sensor, and the other is an infrared sensor (or infrared sensing switch).

[0005] When the sound sensor is in use, people enter the corridor and create noise to control the lights and delay control. However, thunder and rain or the sound of sirens outside the house may cause misjudgment of the corridor lighting control system, resulting in loss and waste of electricity resources.

[0006] Touch sensing is to light up the light by touching it with a human hand. On the one hand, it is unhygienic to use and may cause cross-infection of viruses. On the other hand, the failure rate of touch sensors is very high and it is very inconvenient to use.

[0007] The infrared sensor will light up when it senses someone entering, that is, when someone passes by the corresponding infrared sensor in the corridor, the light controlled by the infrared sensor will light up immediately. Sometimes, only one of the adjacent lights needs to be lit to achieve the lighting effect, and all lights will light up when someone passes by, causing unnecessary waste. Summary of the invention:

[0009] The present invention is to solve the above problems in the prior art and provide a lighting energy-saving system and method for green buildings.

[0010] The technical solutions adopted in the present invention are:

[0011] A lighting energy-saving method for green buildings, comprising:

[0012] 1) Set the lighting logic operation time period: set the lighting logic operation time period of the lighting lamp in the memory;

[0013] 2) Recording the flow data of pedestrians in the corridor: Recording the flow of pedestrians in the corridor during the set time period in step 1) through a proximity sensor, and storing the pedestrian flow data in a storage unit, which continuously records the flow data of pedestrians in the corridor for 30 days;

[0014] 3) Division of pedestrian flow time periods: The controller divides the set time periods into peak periods and off-peak periods according to the pedestrian flow data of the last 30 days stored in the storage unit;

[0015] 4) Lighting logic setting: human infrared switches are arranged at intervals, and one human infrared switch controls the turning on of one lamp; during peak hours, when a human enters the sensing area of ​​the human infrared switch, the lamp controlled by the human infrared switch turns on. The human infrared switches arranged on both sides of the lit lamp are turned off regardless of whether there are pedestrians passing in their sensing areas. The remaining lamps turn on normally after the human infrared switch senses the human body, and the lit lamps turn off after a delay of 15 seconds;

[0016] In the low peak period, when a human body enters the sensing area of ​​the human infrared switch, the lighting lamp controlled by the human infrared switch lights up and remains on for a long time. Only when the human body leaves the sensing area of ​​the human infrared switch, the lit lighting lamp will turn off within 5 seconds.

[0017] Furthermore, the sensing area of ​​each human infrared switch is K, the sensing areas of two adjacent human infrared switches do not overlap each other, and the interval between the two sensing areas K is 80-120 cm.

[0018] Furthermore, the lighting logic operation time period is: 15:30-5:00 in summer; other seasons: 18:00-5:30.

[0019] Furthermore, the proximity sensor is arranged at the entrance of the corridor.

[0020] Furthermore, when dividing the peak period and the off-peak period, the number of people passing by the proximity sensor within three consecutive hours during the set time period of each day in the last 30 days is counted, and if it reaches 15 or more, then the time period is marked as the peak period of that day, and the rest are off-peak periods. Then the average time period of all the peak periods in the 30 days is taken as the peak period of the 30 days.

[0021] The present invention also discloses a lighting energy-saving system for green buildings, comprising:

[0022] A proximity sensor is provided at the entrance of the corridor to sense the entry and exit of people in the corridor;

[0023] A memory, when the proximity sensor senses that someone passes by the proximity sensor, the memory stores the time when the person passes by the proximity sensor;

[0024] lighting,

[0025] Human infrared switch: within the set time, the human infrared switch is used to control the lighting of the light;

[0026] The controller is used to control the storage operation of the memory and control whether the human infrared switch works.

[0027] The present invention has the following beneficial effects:

[0028] The present invention divides the time periods into high and low peaks according to the flow of people at night, and adopts different lighting logics for high and low peaks, which is more energy-efficient. The time period for the peak period is dynamically acquired based on the average flow of people in the last 30 days, which is more intelligent to use.

[0029] During peak hours, people are coming and going and the movements are relatively dense. Therefore, when a person comes, only the lights in the area where he is located are turned on. The lights in the adjacent areas will not be turned on regardless of whether there are people in them. This saves energy and does not affect the lighting.

[0030] During off-peak hours, when pedestrian flow is low, the light will come on as long as someone passes by, and will remain on as long as the person does not leave the sensing area, reducing the sense of security of pedestrians in the dark when there is little pedestrian flow. Description of the drawings:

[0032] FIG1 is a structural diagram of the present invention.

[0033] Figure 2 and Figure 3 This is an application scenario during peak hours.

[0034] Figure 4 shows the application scenario in the low-peak period. Specific implementation method:

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Embodiment 1

[0038] like Figure 1 As shown, the present invention is a lighting energy-saving system for green buildings, including a proximity sensor, a memory, a lighting lamp, a human infrared switch and a controller. The proximity sensor is arranged at the entrance of the corridor to sense the situation of people entering and leaving the corridor; when the proximity sensor senses that someone passes by the proximity sensor, the memory stores the time when the person passes by the proximity sensor; within the set time, the human infrared switch is used to control the lighting of the lighting lamp; the controller is used to control the storage operation of the memory and control whether the human infrared switch works.

[0039] Embodiment 2

[0040] Based on the energy-saving system of the first embodiment, the present invention provides a lighting energy-saving method for green buildings, which is as follows:

[0041] 1) Set the lighting logic operation time period: Set the lighting logic operation time period of the lighting lamp in the memory, generally: 15:30-5:00 in summer; other seasons: 18:00-5:30. Users can also set other time periods according to the actual use environment.

[0042] 2) Recording the flow data of pedestrians in the corridor: The flow of pedestrians in the corridor during the set time period in step 1) is recorded by a proximity sensor installed at the entrance of the corridor, and the pedestrian flow data is stored in a storage unit. The storage unit continuously records the flow data of pedestrians in the corridor for 30 days;

[0043] 3) Division of pedestrian flow time periods: The controller divides the set time periods into peak periods and off-peak periods according to the pedestrian flow data of the last 30 days stored in the storage unit;

[0044] When dividing the peak and off-peak periods, the number of people passing by the proximity sensor within three consecutive hours during the set time period every day in the last 30 days is counted. If more than 15 people pass by the proximity sensor within three consecutive hours, the time period is marked as the peak period of the day, and the rest are off-peak periods. Then the average time period of all peak periods in the 30 days is taken as the peak period of the 30 days.

[0045] There can be one or more peak segments per day. When taking the average value, if there are only 5 or fewer days with two or more peak segments in 30 days per month, only one peak segment with a time period close to the other 25 will be taken from the 5 days, and then the average value of the 30 days will be taken. The other peak segments in the 5 days can be ignored and classified as low peak segments. Only when there are more than 5 days with multiple peak segments, the average value of the second peak segment will be taken.

[0046] 4) Lighting logic setting: human infrared switches are arranged at intervals, and one human infrared switch controls the turning on of one lighting lamp. The sensing area of ​​each human infrared switch is K. The sensing areas of two adjacent human infrared switches do not overlap, and the interval between the two sensing areas K is 80-120cm.

[0047] During peak hours, when a person enters the sensing area of ​​the human infrared switch, the lights controlled by the human infrared switch light up. The human infrared switches arranged on both sides of the lit lights are turned off regardless of whether there are pedestrians passing through their sensing areas. The remaining lights are turned on normally after the human infrared switch senses the human body, and the lit lights are turned off after a delay of 15 seconds.

[0048] In the low peak period, when a human body enters the sensing area of ​​the human infrared switch, the lighting lamp controlled by the human infrared switch lights up and remains on for a long time. Only when the human body leaves the sensing area of ​​the human infrared switch, the lit lighting lamp will turn off within 5 seconds.

[0049] Embodiment 3

[0050] Figures 2 to 4 In the figure, the direction of AE is upstairs, the direction of EA is downstairs, and the direction of cutting is upstairs and downstairs.

[0051] As a peak application scenario, such as Figure 2 and Figure 3 During peak hours, when the infrared switches in areas B and E sense that a pedestrian has entered, the lights in areas B and E light up, and the lights in areas A and C adjacent to area B go out. Similarly, the lights in the two areas adjacent to area E also go out. 15 seconds after the person leaves area B, the lights in area B go out. Since people go up and down stairs frequently during peak hours, when there are pedestrians in each area, that is, there are pedestrians in areas BCD, then the area that senses the pedestrian first will have its lights on first, that is, Figure 3 Among them, B and D sense the pedestrians before C, and then the lights in the two adjacent areas in area B and area D are turned off.

[0052] As a low-peak application scenario, such as Figure 4 When a person enters area B or C, the lights in area B or C will light up and remain on for a long time, and the lights in other areas will not light up. Only when a person leaves area B or C, the lights in area B or C will turn off within 5 seconds.

[0053] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
