Description

Technical Field

[0001] The present invention relates to the field of intelligent lighting technology, and in particular to a building intelligent lighting control system and method. Background Art

[0002] At present, public area lighting management in buildings mostly adopts a unified control method, usually turning lights on or off according to a preset time plan. Although this method can ensure sufficient lighting within the set time period, it cannot be flexibly adjusted according to the actual environment and needs, resulting in energy waste.

[0003] In addition, a large number of lighting fixtures are usually installed in the public areas of buildings to provide lighting services. For lighting fixtures that have been in use for a long time, the traditional maintenance method relies on manual observation and judgment, that is, judging whether the lighting fixture is faulty by whether the lighting is abnormal. This method is not only inefficient, but also has the limitation of being unable to predict when the lighting fixture is about to break. When some lighting fixtures fail, due to failure to discover and replace them in time, some areas in the building may be insufficiently lit, posing potential safety hazards to office workers in their daily work.

[0004] Therefore, the existing lighting control systems urgently need to be improved in terms of intelligent management, energy saving and consumption reduction, and equipment maintenance to meet the needs of modern building management. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a building intelligent lighting control system and method, which solves the problems in the background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A building intelligent lighting control system, comprising:

[0007] An area division module is used to determine all public areas in the building and define them as a collection area, mark each area in the collection area, and then divide the marked areas into long dark areas or variable areas to form a long dark area subset and a variable area subset;

[0008] A lighting phase area determination module, used to determine each change area in the change area subset based on light intensity, and when the light intensity of the change area is lower than a preset value, the change area is determined to enter the lighting phase, otherwise it does not enter the lighting phase, and then determine the area in the lighting phase at the current moment;

[0009] The personnel sensing module is used to obtain all areas in the lighting link in real time, and use the passive infrared sensor to judge whether a person has passed through the lighting link area. If it is judged that an office worker has entered the lighting link area, the control center will control to turn on all the lights in the specific public area;

[0010] The control platform is used to receive the command signal sent by the passive infrared sensor, identify the command information, determine the specific public area, and control the lighting in the specific public area to turn on;

[0011] The lighting lamp monitoring module is used to mark the lighting lamps in all areas of the collection area, and then detect the turned-on lighting lamps in the area in the lighting link every time after turning on the lighting lamps, to determine whether each lighting lamp in the area in the lighting link is damaged or abnormal.

[0012] As a further solution of the present invention: in the area division module, the specific method of marking each area in the set area is:

[0013] The public area is marked by the specific floor and corresponding position of the building, and the label Q i-j Determine the label of each area, where i represents the number of floors in the building, j represents the jth area from left to right on the i-th floor, and 1≤i≤n, n is the total number of floors in the building, j=1, ..., m, m is the total number of areas on the i-th floor, and the value of m varies relatively with different numbers of floors.

[0014] As a further solution of the present invention: the specific method of dividing the marked area into a long dark area or a changing area is:

[0015] Each marked area is taken as the target area for judgment;

[0016] Assume that the change of light intensity over time in the target area is represented by the function I(t), where t represents time and I(t) is the light intensity at that time point;

[0017] Then set two thresholds I min and ΔI max , where I min Expressed as the minimum threshold of light intensity, ΔI max It is expressed as the maximum change threshold of light intensity;

[0018] If I(t) min , The target area is divided into a long dark area, otherwise it enters the subsequent judgment;

[0019] ​Among them, t1 represents the start time of a day, and t2 represents the end time of a day;

[0020] In the subsequent judgment, if The target area is divided into a changing area, and vice versa, the target area is divided into a long dark area;

[0021] Among them, [t3,t4] represents a period of time in a day, and [t3,t4]∈[t1,t2].

[0022] As a further solution of the present invention: in the lighting link area determination module, when the light intensity of the changing area is lower than a preset value, the specific content of determining that the changing area enters the lighting link is:

[0023] The light intensity I of the current changing area is obtained in real time through the light sensor 实 , judge I 实 Is it less than the threshold I min , if it is less than the threshold I min When , it is determined that the changed area enters the lighting stage, wherein the preset value is the threshold value I min ;

[0024] Then, each change area in the change area subset is judged at the same time in the above manner to determine the area in the lighting stage at the current moment.

[0025] As a further solution of the present invention: in the personnel sensing module, the specific content of judging whether a person has passed through the area in the lighting link is:

[0026] The thermal radiation signals of office workers are detected by passive infrared sensors. The sensors can effectively sense human activities in dark or low-light environments. When the sensor detects that a person has entered an area in the lighting link, the specific public area number Q of the area in the lighting link is used. i-j , send a signal with label Q i-j The control platform receives the command signal containing the label Q i-j When receiving the instruction information, the specific public area is determined and the lighting in the specific public area is controlled to turn on;

[0027] Wherein, each long dark area in the long dark area subset and the area where the lighting link area determination module can determine that the change area enters the lighting link are all installed with a passive infrared sensor.

[0028] As a further solution of the present invention: in the lighting lamp monitoring module, the specific content of marking the lighting lamps in all areas of the collection area is:

[0029] Get the label Q of each area in turn i-j ;

[0030] Determine area Q i-j The total number of lighting lamps in z;

[0031] For region Q i-j The lights in the i-j-k , where 1≤k≤z, and z varies according to the region Q i-j There are different values.

[0032] As a further solution of the present invention: the specific content of judging whether each lighting lamp in the area of ​​the lighting link is damaged or abnormal is:

[0033] Determine a specific public area in the area in the lighting link, where the specific public area is a public area where the lighting has been turned on by the control platform;

[0034] Then determine the specific number of lighting lamps in the specific public area;

[0035] The current value of each lighting lamp during the turning-on process is recorded, and a preliminary identification is first performed to identify the lighting lamp whose current does not fluctuate during the turning-on process. If a lighting lamp with no current fluctuation is identified, the lighting lamp is determined to be a damaged lighting lamp;

[0036] Then, the remaining lighting lamps are judged as abnormal and the abnormal lighting lamps are identified.

[0037] As a further solution of the present invention: the specific method of performing abnormality judgment on the remaining lighting lamps and determining the abnormal lighting lamp is:

[0038] Obtain the key current characteristics of each lighting lamp when it is turned on, including the starting current peak, stable current and starting time, which are marked as G peak , G stable , T stable ;

[0039] And set characteristic thresholds for the current characteristics, which are:

[0040] Peak current threshold range: [G peak,min , G peak,max ];

[0041] Stable current threshold range: [G stable,min , G stable,max ];

[0042] Start time threshold range: [T peak,min , T peak,max ];

[0043] Determine whether the current characteristic of each lighting lamp exceeds the characteristic threshold, exclude the lighting lamps whose current characteristics exceed the characteristic threshold, and determine the lighting lamps in abnormal condition;

[0044] The lights with abnormal conditions are marked with a combination of 1, 2, 3, 4, 5, and 6. There are 6 types of abnormal conditions, which are represented by 1, 2, 3, 4, 5, and 6 respectively;

[0045] Among them, 1 represents G peak <G peak,min , the starting current peak is too low;

[0046] 2 represents G peak >G peak,max , the starting current peak is too high;

[0047] 3 represents G stable <G stable,min , the stable current is too low;

[0048] 4 represents G stable >G stable,max , the stable current is too high;

[0049] 5 represents T peak <T peak,min , the startup time is too short;

[0050] 6 represents T peak >T peak,max , the startup time is too long;

[0051] After the lighting lamp in the abnormal condition is determined, the lighting lamp in the abnormal condition is determined as an abnormal lighting lamp.

[0052] As a further solution of the present invention, it also includes: a fault repair module, which is used to obtain the damaged and abnormal lighting lamps in the area of ​​the lighting link determined by the lighting lamp monitoring module, and notify the staff to replace or repair the damaged lighting lamps.

BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The present invention will be further described below in conjunction with the accompanying drawings.

[0064] Figure 1 This is a structural framework diagram of an intelligent building lighting control system of the present invention;

[0065] Figure 2 The present invention is a flow chart of a building intelligent lighting control method. DETAILED DESCRIPTION

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] Embodiment 1

[0068] Please refer to the figure, the present invention provides a building intelligent lighting control system, including: a zone division module, a lighting link zone determination module, a personnel sensing module, a control platform, a lighting lamp monitoring module and a fault maintenance module;

[0069] An area division module is used to determine all public areas in the building and define them as a collection area, mark each area in the collection area, and then divide the marked areas into long dark areas or variable areas to form a long dark area subset and a variable area subset;

[0070] The specific method of marking each area in the set area is:

[0071] The public area is marked by the floor and location of the building where it exists, and the label Q i-j Determine the label of each area, where i represents the number of floors in the building, j represents the jth area from the left to the right on the i-th floor, and 1≤i≤n, n is the total number of floors in the building, j=1, ..., m, m is the total number of areas on the i-th floor, and the value of m varies relatively according to the number of floors;

[0072] Specifically, the explanations for the long dark area and the changing area are:

[0073] Long dark areas are areas with insufficient light. When office workers pass by, they must rely on lighting to see the surrounding environment clearly.

[0074] The changing area is the area where light changes over time, mainly due to the changes caused by sunlight. Generally, from 8 am to 6 pm, the surrounding environment can be seen clearly without the illumination of lights. At night, the surrounding environment can only be seen clearly with the illumination of lights. This is mainly determined by judging the intensity of light. Such an area is called a changing area.

[0075] The specific method of dividing the marked area into a long dark area or a changing area is:

[0076] Each marked area is taken as the target area for judgment;

[0077] Assume that the change of light intensity over time in the target area is represented by the function I(t), where t represents time and I(t) is the light intensity at that time point;

[0078] Then set two thresholds I min and ΔI max , where I min It is expressed as the minimum threshold of light intensity. When the light intensity is lower than this threshold, it is considered that the light is insufficient and the area needs lighting. ΔI max It is expressed as the maximum change threshold of light intensity. When it exceeds this change threshold, it means that the light level in the area changes significantly over time, and the two thresholds I min and ΔI max The specific parameters are selected or determined by professional staff;

[0079] If I(t) min , The target area is divided into a long dark area, otherwise it enters the subsequent judgment;

[0080] Among them, t1 represents the start time of the day, that is, 0:00 a.m., and t2 represents the end time of the day, that is, 11:59 p.m.;

[0081] During a day, if the light intensity changes significantly over time, that is, the rate of change of light intensity is greater than the threshold ΔI max , then through the first-order derivative of the light intensity To determine whether the target area is a change area;

[0082] In the subsequent judgment, if The target area is divided into a changing area, and vice versa, the target area is divided into a long dark area;

[0083] Among them, [t3, t4] represents a certain period of time in a day, that is, [t3, t4]∈[t1, t2]. The specific time is selected or determined by professional staff, and is generally in the time period of a day when the light changes greatly, such as the time period from 4 am to 8 am or the time period from 5 pm to 8 pm;

[0084] It should be noted that when the target area is not divided into a long dark area and enters the subsequent judgment, the result of the calculated first-order derivative in the time period [t3, t4] is not greater than the threshold ΔI max When , it indicates that the light in the area is in a stable but dark state, so such a target area is classified as a long dark area;

[0085] ​This module optimizes the use of lighting according to lighting conditions by marking and dividing all public areas in the building into long dark areas and variable areas. In long dark areas, since the light is always insufficient, the system ensures that these areas are continuously illuminated to provide a safe passage environment. For variable areas, the system monitors the light intensity in real time and intelligently determines whether lighting is needed. This precise division greatly reduces energy waste, makes the operation of the lighting system more efficient and reasonable, and ensures the safety and comfort of the personnel activity areas.

[0086] A lighting phase area determination module, used to determine each change area in the change area subset based on light intensity, and when the light intensity of the change area is lower than a preset value, the change area is determined to enter the lighting phase, otherwise it does not enter the lighting phase, and then determine the area in the lighting phase at the current moment;

[0087] The lighting phase is represented as a time period during which the surrounding environment can only be seen clearly through lighting; each long dark area in the long dark area subset is in the lighting phase;

[0088] When the light intensity of the changing area is lower than the preset value, the specific content of determining that the changing area enters the lighting stage is:

[0089] The light intensity I of the current changing area is obtained in real time through the light sensor 实 , judge I 实 Is it less than the threshold I min , if it is less than the threshold I min When , it is determined that the changed area enters the lighting stage, wherein the preset value is the threshold value I min ;

[0090] Then, each change area in the change area subset is judged at the same time in the above-mentioned manner to determine the area in the lighting link at the current moment;

[0091] This module dynamically determines whether the changing area enters the lighting stage based on real-time light intensity monitoring; by introducing a light intensity threshold, it ensures that lighting is not activated when there is sufficient natural light, thereby saving a lot of energy during the period of good light; only when the light intensity is lower than the preset value, the area will be judged as needing lighting; this intelligent judgment effectively reduces unnecessary power consumption and improves the efficiency of energy use. At the same time, it enables the system to flexibly respond to different environmental conditions, ensuring that office and public areas can provide sufficient lighting in a timely manner when needed;

[0092] The personnel sensing module is used to obtain all areas in the lighting link in real time, and use the passive infrared sensor (PIR) to judge whether a person has passed through the lighting link area. If it is judged that an office worker has entered the lighting link area, the control center will control to turn on all the lights in the specific public area so that the office worker passing by can see the surrounding environment clearly;

[0093] The personnel judgment is to judge whether the office personnel have entered the area;

[0094] Wherein, all the areas in the lighting phase include all the areas in the long dark area subset and the areas in the changing area subset determined by the lighting phase area determination module to enter the lighting phase;

[0095] It should be noted that at different times, the number of regions determined by the lighting link region determination module to enter the lighting link in the change region sub-set is different. In layman's terms, at different times, whether a change region enters the lighting link is determined based on I 实 Determined by comparison with a preset value;

[0096] The specific content of judging the personnel in the lighting area is as follows:

[0097] The thermal radiation signals of office workers are detected by passive infrared sensors. The sensors can effectively sense human activities in dark or low-light environments. When the sensor detects that a person has entered an area in the lighting link, the specific public area number Q of the area in the lighting link is used. i-j , send a signal with label Q i-j The control platform receives the command signal containing the label Q i-j When receiving the instruction information, the specific public area is determined and the lighting in the specific public area is controlled to turn on to ensure that the office staff can see the surrounding environment clearly;

[0098] Wherein, each long dark area in the long dark area subset and the area where the lighting link area determination module can determine that the change area enters the lighting link are installed with a passive infrared sensor;

[0099] The module uses passive infrared sensors to detect whether office workers have entered the lighting area, thereby realizing intelligent lighting control based on human activities. When someone enters an area that needs lighting, the lights are automatically turned on, and when the person leaves, the lights are automatically turned off. This design not only improves the intelligence of the building lighting system, but also significantly saves energy, especially when there are few people, avoiding unnecessary long-term lighting. At the same time, it ensures that when people enter any area that needs lighting, they can immediately obtain a safe and appropriate lighting environment, improving user experience and safety.

[0100] The control platform is used to receive the command signal sent by the passive infrared sensor, identify the command information, determine the specific public area, and control the lighting in the specific public area to turn on;

[0101] A lighting lamp monitoring module is used to mark the lighting lamps in all areas of the collection area, and then perform a detection on the lighting lamps in the area in the lighting link after each lighting lamp is turned on, to determine whether each lighting lamp in the area in the lighting link is damaged or abnormal;

[0102] The specific content of marking the lighting lamps in all areas of the collection area is:

[0103] Get the label Q of each area in turn i-j ;

[0104] Determine area Q i-j The total number of lighting lamps in z;

[0105] For region Q i-j The lights in the i-j-k , where 1≤k≤z, and z varies according to the region Q i-j There are different values;

[0106] The specific content of judging whether each lighting lamp in the lighting area is damaged or abnormal is as follows:

[0107] Determine a specific public area in the area in the lighting link, where the specific public area is a public area where the lighting has been turned on by the control platform;

[0108] Then determine the specific number of lighting lamps in the specific public area;

[0109] The current value of each lighting lamp during the turning-on process is recorded, and a preliminary identification is first performed to identify the lighting lamp whose current does not fluctuate during the turning-on process. If a lighting lamp with no current fluctuation is identified, the lighting lamp is determined to be a damaged lighting lamp;

[0110] Then, the remaining lighting lamps are judged to be abnormal, and the abnormal lighting lamp is determined;

[0111] The specific method of judging the abnormality of the remaining lighting lamps and determining the abnormal lighting lamp is:

[0112] Obtain the key current characteristics of each lighting lamp when it is turned on, including the starting current peak, stable current and starting time, which are marked as G peak , G stable 、T stable ;

[0113] The starting current peak, stable current and starting time are explained as:

[0114] The starting current peak is the instantaneous maximum current value at startup;

[0115] The stable current is the stable current value after the lighting lamp works normally;

[0116] The start-up time is the time required for the lighting to stabilize;

[0117] And set characteristic thresholds for the current characteristics, which are:

[0118] Peak current threshold range: [G peak,min , G peak,max ];

[0119] Stable current threshold range: [G stable,min , G stable,max ];

[0120] Start time threshold range: [T peak,min , T peak,max ];

[0121] Determine whether the current characteristic of each lighting lamp exceeds the characteristic threshold, exclude the lighting lamps whose current characteristics exceed the characteristic threshold, and determine the lighting lamps in abnormal condition;

[0122] It should be noted that the lighting lamp in abnormal condition is a lighting lamp whose any characteristic of the current characteristic exceeds the corresponding characteristic threshold range;

[0123] The lights with abnormal conditions are marked with a combination of 1, 2, 3, 4, 5, and 6. There are 6 types of abnormal conditions, which are represented by 1, 2, 3, 4, 5, and 6 respectively;

[0124] Specifically, 1 represents G peak <G peak,min , the starting current peak is too low, indicating that there may be an abnormality in the power supply or drive circuit;

[0125] 2 represents Gpeak >G peak,max , the starting current peak is too high, indicating that the current is too large and the lamp may be about to be damaged;

[0126] 3 represents G stable <G stable,min , the stable current is too low, the surface lighting may be aged or the power may decrease;

[0127] 4 represents G stable >G stable,max , the stable current is too high, indicating that the lighting power may be overloaded;

[0128] 5 represents T peak <T peak,min , the startup time is too short, indicating that there may be a power supply or drive problem causing the rapid startup;

[0129] 6 represents T peak >T peak,max , the startup time is too long, indicating that the lighting startup process may be blocked or the power is insufficient;

[0130] It should be noted that the combination of marking 1, 2, 3, 4, 5, and 6 for the abnormal lighting lamps is further explained. If the starting current peak value G of a lighting lamp in an abnormal condition is peak Less than the peak current threshold G peak,min , and also satisfies G stable >G stable,max , then the lighting of the abnormal condition is marked by numbers 1 and 3;

[0131] After the lighting lamp in the abnormal condition is determined, the lighting lamp in the abnormal condition is judged as an abnormal lighting lamp;

[0132] This module is responsible for real-time monitoring of each lamp in the lighting system to ensure that each lamp is in normal working condition. By monitoring the current characteristics, the system can quickly identify damaged or abnormal lamps and determine the specific fault type based on the set threshold. The monitoring function of this module not only improves the operating safety and stability of the system, but also reduces the frequency of hidden faults. For managers, they can find problems in advance and repair them before the fault occurs, thus avoiding the inconvenience caused by lamp failure and ensuring that the lighting environment in the building is continuously in the best condition.

[0133] A fault repair module is used to obtain the damaged and abnormal lighting lamps in the area of ​​the lighting link determined by the lighting lamp monitoring module, and determine the area and specific lighting lamp positions of the damaged or abnormal lighting lamps according to the lighting lamp marks, and notify the staff to replace the damaged lighting lamps, and for the abnormal lighting lamps, to know the abnormal conditions of the lighting lamps according to the digital marks and perform repairs;

[0134] This module analyzes the detection results of the lighting monitoring module, promptly detects and records damaged or abnormal lighting, and ensures efficient maintenance work. The system can accurately locate the area where the damaged lighting is located, and understand the specific situation of the lighting failure through abnormal marking, thus providing clear guidance for maintenance personnel. Through this module, maintenance personnel can quickly locate the problem lamps and carry out targeted maintenance or replacement work according to the marked fault type. The existence of this module effectively reduces the system downtime, improves maintenance efficiency, reduces labor costs, and ensures the long-term reliable operation of the building lighting system.
