Description

Technical Field

[0001] This invention relates to the technical field of lighting control, specifically to a lighting control system with infrared barcode scanning and sensor linkage. Background Technology

[0002] To achieve the energy-saving lighting function of "lights on when people come and off when people leave," existing lighting control systems have been developed. However, these systems still have the following defects and shortcomings: 1) Existing lighting control systems cannot achieve lighting on / off control and brightness adjustment, intelligent group control of lighting fixtures, paperless periodic statistics and early warning of power consumption, intelligent selection and custom control of lighting strategy modes, and sensor-linked control of multiple control modes.

[0003] 2) The existing lighting control systems often use integrated lighting fixtures, which are prone to thermal coupling and electromagnetic interference, and have a high probability of cascading failures. At the same time, the concentrated heat dissipation points can easily lead to overheating of internal components, which can have an adverse effect on temperature-sensitive devices such as power supplies and intelligent controllers. In addition, the explosion-proof function is insufficient. Once an electrical fault causes a spark or internal explosion, it can easily spread into the interior of the lighting fixture, causing damage to the lighting fixture and posing a safety threat to the control components connected to the lighting fixture.

[0004] 3) In the operation of traditional intelligent lighting systems, the collection and entry of equipment data heavily rely on manual paper records and subsequent manual input into the system platform. This not only leads to problems such as easy errors in recording, easy loss of documents, difficulty in searching, and lag in entry, but also makes it inconvenient to carry paper documents such as location maps, barcode scanning record sheets, and equipment lists, which are easily damaged or lost. The subsequent data sorting, archiving, and retrieval also require a lot of manpower and resources, and are not cost-effective. Furthermore, it is difficult to quickly locate specific lighting fixtures and intuitively view the distribution and status of equipment.

[0005] 4) Existing lighting control systems often use a single-device control method, which cannot effectively group the lighting fixtures according to actual lighting needs, nor can they achieve corresponding control based on the operating status of the individual lamp controller and the linkage relationship of the lighting fixtures.

[0006] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Summary of the Invention

[0007] To address the shortcomings and deficiencies in existing technologies, this invention provides a lighting control system with infrared barcode scanning and sensor linkage.

[0008] To address the shortcomings and deficiencies in existing technologies, the present invention provides the following specific solution: A lighting control system with infrared barcode scanning and sensor linkage, characterized in that: the system includes: The lighting module includes a lighting fixture connected to a driving power supply; a single-lamp controller connected to the driving power supply to control the on / off state and adjust the output power of the driving power supply; and multiple single-lamp controllers connected to a centralized controller via signals. The infrared microwave sensing module is connected to the driving power supply through a single lamp controller. The infrared microwave sensing module can analyze the motion state of the target object and determine whether there is a dynamically moving target, and distinguish between day and night by calibrating the ambient illuminance. Thus, the single lamp controller controls and adjusts the output power supplied by the driving power supply to the lamp. The infrared scanning module sends a parameter reading command for the corresponding lamp to the single lamp controller. After receiving the parameter reading command, the single lamp controller returns a unique code and device data corresponding to the lamp. The device data is uploaded to the service center in a timed or active manner for periodic status reporting and alarm management. The group control module is connected to the lighting module to group the lighting fixtures as needed. It is configured according to the user's actual situation, determines the individual lamp controllers corresponding to each lighting fixture in the same group, and forms a correspondence table between the unique code and device serial number of each individual lamp controller. The table is then sent to the corresponding individual lamp controllers. When any individual lamp controller in the same group receives a control command, it will broadcast the control command through a carrier channel in the form of group broadcast. When other individual lamp controllers in the same group receive the control command, they will determine whether to perform dimming action based on their own device serial number and lamp control range value. The lighting strategy module has multiple preset lighting working strategies, and the user can select at least one of the lighting working strategies as needed. The lighting customization module allows users to customize their lighting needs, enabling them to customize lighting strategies as required. The energy consumption statistics module performs electricity consumption statistics for lighting, analyzes the electricity consumption data, and generates energy consumption reports through the system. The sensor linkage module can control the lamps in a single-device control mode, a multi-device control mode, or a linkage control mode.

[0009] As a further preferred embodiment of the present invention, the lamp is an explosion-proof lamp, including a wiring cavity, an electrical cavity and a light source cavity that are interconnected. The wiring cavity is connected to the driving power supply through a built-in circuit. The single lamp controller is disposed inside the electrical cavity. The light source cavity is provided with a light source board. The light source board is connected to the single lamp controller through a built-in antenna. A power supply heat dissipation fin is disposed on the outside of the electrical cavity. A light source heat dissipation fin is disposed on the outside of the light source cavity.

[0010] As a further preferred embodiment of the present invention, when the infrared microwave sensing module analyzes the motion state of the target object and determines whether there is a dynamically moving target: First, check if there are any dynamically moving targets: When no moving target is detected, the drive power supply is kept inactive by the single lamp controller. When a dynamically moving target is detected, the ambient illuminance value at that moment is then measured: If the ambient illuminance value is greater than the preset light sensing threshold, the infrared microwave sensing module will not send a sensing signal to the single lamp controller, and the single lamp controller will remain in its original state. If the ambient illuminance does not exceed the preset light sensing threshold, the infrared microwave sensing module sends a corresponding sensing signal to the single lamp controller, which then controls the corresponding action of the drive power supply.

[0011] As a further preferred embodiment of the present invention, the lighting control range value can be obtained in the following manner: A) The lighting control range value is pre-configured by the system; or B) The lighting control range value can be automatically changed over time; or C) The lamp control range value can be automatically adjusted by the single lamp controller based on the number of control commands received by the single lamp controllers in the same group within a preset statistical sampling time period: When the number of times a single lamp controller in the same group receives control commands exceeds the preset number within a preset statistical sampling period, the single lamp controller will increase the lamp control range value. When the number of times the single lamp controller in the same group receives control commands within the preset statistical sampling time period does not exceed the preset number, the single lamp controller controls to reduce the lamp control range value; Within the preset valid window period: If the lighting control range value obtained by method B) does not exceed the lighting control range value obtained by method A), then the lighting control range value obtained by method A) shall be selected. If the lighting control range value obtained by method B) is greater than the lighting control range value obtained by method A), then the lighting control range value obtained by method B) shall be selected. When the time exceeds the preset effective window period, the lighting control range value obtained by method C) is selected.

[0012] As a further preferred embodiment of the present invention, for a lighting environment with linearly arranged lamps, the light control range value is taken as a light control range serial number value, and the light control range serial number value satisfies: m min ≤m≤m max ; wherein, m is the light control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range; m min is the minimum boundary value of the light control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range, and satisfies: m min =t-c, and when (t-c) < a, the minimum boundary value m min =a; m max is the maximum boundary value of the light control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range, and satisfies: m max =t+c, and when (t+c) > b, the maximum boundary value m max =b; wherein, in the lighting environment with linearly arranged lamps, a is the device serial number of the first individual lamp controller, b is the device serial number of the last individual lamp controller, c is the light control range value; t is the t-th individual lamp controller that receives the control instruction between a and b, and satisfies a≤t≤b.

[0013] As a further preferred embodiment of the present invention, for a lighting environment with lamps arranged in a matrix, the light control range value is taken as a light control range coordinate value, and the light control range coordinate value satisfies: x min ≤x≤x max ; y min ≤y≤y max ; wherein, (x, y) is the light control range coordinate value of the i-th individual lamp controller that receives the control instruction within the control range; The minimum coordinate of the coordinate system is (x min , y min ), and the maximum coordinate of the coordinate system is (x max , y max ); The minimum boundary value of the light control range coordinate value of the i-th individual lamp controller that receives the control instruction within the control range is (x1, y1); and satisfies: x1=x i -c; y1=y i -c; If x1<x minThen x1 = x min If y1 <y min Then y1=y min ; The maximum boundary value of the lamp control range coordinates of the i-th lamp controller receiving the control command within the control range is (x2, y2); and satisfies: x2=x i +c; y2=y i +c; If x2>x max Then x2 = x max ;if y2>y max Then y2=y max ; And among them, (x) i y i ) represents the coordinates of the i-th single-lamp controller that received the control command, and c represents the lamp control range value.

[0014] As a further preferred embodiment of the present invention, the lighting strategy module includes at least a variety of preset lighting working strategies, such as sunrise and sunset lighting mode, motion sensing lighting mode, timed control lighting mode, and strategy combination lighting mode.

[0015] As a further preferred embodiment of the present invention, when the sensing linkage module adopts a single-device control mode, upon detecting a control command, it first determines the operating status of the single-lamp controller itself: If the operation is in automatic mode and no control command is sent, the lighting fixtures will be dimmed according to the preset lighting strategy; if a control command has been sent, only the delay period will be reset and no further control command will be sent. If the running status is manual, no action will be taken.

[0016] As a further preferred embodiment of the present invention, when the sensing linkage module adopts a multi-device control mode... The single-lamp controller first determines its own operating status: If the operation is in automatic mode and no control command is sent, the lighting fixtures will be dimmed according to the preset lighting strategy; if a control command has been sent, only the delay period will be reset and no further control command will be sent. If the running status is manual, no action will be taken; After the lighting controller finishes processing, the lighting data is uploaded to the central controller. The lighting data includes at least the device serial number, sensing signal, delay period, and lighting operation status data. After acquiring the lighting data uploaded by the individual lamp controller, the centralized controller randomly acquires the operating status of the lamps within the lighting control range of the preset lighting strategy based on the binding relationship between the lamps and the preset lighting strategy. When the proportion of the acquired operating status as automatic is less than a preset threshold, the centralized controller does not issue a control command; otherwise, it issues a control command corresponding to the preset lighting strategy.

[0017] As a further preferred embodiment of the present invention, when the sensing linkage module adopts a linkage control mode... When the infrared microwave sensing module detects a dynamically moving target, the single-lamp controller connected to the infrared microwave sensing module first determines the operating status of the single-lamp controller itself: If the single-lamp controller is determined to be in manual mode, then no control is performed. If the single-lamp controller is determined to be in automatic mode, then the dimming control of the lamps is performed through the single-lamp controller according to the current preset lighting strategy. After the control is completed, the lamp data is uploaded to the central controller through the individual lamp controller; After receiving the uploaded lighting data, the central controller first determines whether it needs to control the lighting fixtures within its control range based on the binding policy configured on the platform. If control is required, it will be controlled according to the preset lighting strategy, and then the lighting data will be uploaded to the server. After receiving the uploaded lighting data, the server first queries the database to check the linkage relationship between the lighting fixture and other lighting fixtures under the same central controller. If a linkage relationship exists, the server will send the preset lighting strategy to the corresponding central controller for execution; otherwise, the server will not process it.

[0018] Compared with existing technologies, the technical effects that this invention can achieve include: 1) This invention provides a lighting control system with infrared scanning and sensor linkage, which can realize the integrated control system of lighting fixtures, including lighting fixture on / off control and brightness adjustment, intelligent group control of lighting fixtures, paperless periodic statistics and early warning of power consumption, intelligent selection and customized control of lighting strategy modes, and multi-control mode sensor linkage control. While realizing paperless energy consumption statistics, it can realize the on / off control and brightness adjustment of a single lighting fixture, realize intelligent group control of multiple lighting fixtures, and further realize the user's personalized control and high-efficiency control of lighting fixtures through intelligent selection and customized control of lighting strategy modes and multi-control mode sensor linkage control.

[0019] 2) This invention provides a lighting control system with infrared scanning and sensor linkage. By configuring the lighting fixture as including interconnected wiring cavities, electrical cavities, and light source cavities, the separate design reduces thermal coupling and electromagnetic interference between different areas due to the different energy densities and protection methods of each cavity, thus lowering the probability of cascading failures. Simultaneously, it effectively prevents explosion propagation. If a cavity experiences a spark or internal explosion due to an electrical fault, the independent cavity structure can prevent the flame from spreading to other cavities through the explosion-proof shell, avoiding pressure overlap and secondary explosions within the cavity. Furthermore, power supply heat dissipation fins are provided on the outside of the electrical cavity, and light source heat dissipation fins are provided on the outside of the light source cavity, effectively separating the heat dissipation paths. Heat from the light source cavity is discharged through the outer light source heat dissipation fins, and heat from the electrical cavity is dissipated through the ventilation structure of the outer power supply heat dissipation fins, preventing heat source superposition that could lead to overheating of internal components and effectively preventing the heat from the light source from affecting temperature-sensitive devices such as the power supply and intelligent controller.

[0020] 3) This invention provides a lighting control system with infrared barcode scanning and sensor linkage. By setting up an infrared barcode scanning module, it not only brings cost advantages but also fundamentally restructures the data acquisition process, realizing closed-loop management of on-site scanning and real-time data entry. It completely eliminates paper-based management and realizes electronic data, saving the transcription process from paper to electronic files, effectively avoiding the risk of data loss due to human negligence, document loss, or entry delays, ensuring the real-time, accuracy, and integrity of data, and reducing the workload of single-lamp data acquisition and entry by more than 10 times, greatly improving the efficiency of project deployment and data initialization. At the same time, by combining the infrared barcode scanning terminal with the system's backend electronic map, specific lighting fixtures can be quickly located, and the distribution and status of equipment can be viewed intuitively. In addition, the infrared barcode scanning module enables real-time visualization of construction progress, facilitating accurate monitoring of on-site construction progress and achieving transparent and refined management of project progress. It also makes installation quality traceable. Each barcode scanning operation records the operator, time, and location (GPS information), forming an unalterable electronic file. If a fault occurs later, it can be quickly traced back to the installation stage, clarifying responsibility and improving project quality.

[0021] 4) This invention provides a lighting control system with infrared scanning and sensor linkage. By setting up a group control module and specifically setting the lighting control range value, it can be obtained in the following ways: A) The lighting control range value is pre-configured by the system; B) The lighting control range value can be automatically changed over time; C) The lighting control range value can be automatically adjusted by the single-lamp controller based on the number of control commands received by the single-lamp controller in the same group within a preset time period. Based on this, specifically set within the preset time period: when the lighting control range value obtained by method B) does not exceed the lighting control range value obtained by method A), the lighting control range value obtained by method A) is selected; when the lighting control range value obtained by method B) is greater than the lighting control range value obtained by method A), the lighting control range value obtained by method B) is selected; and when the preset time period is exceeded, the lighting control range value obtained by method C) is selected. This allows the lighting control range value to automatically switch to the optimal strategy under different scenarios, different time periods, and different usage frequencies, without wasting energy, without affecting the user experience, and intelligently adapting to changes in pedestrian flow. By using pre-set system parameters as a foundation, the system provides lighting fixtures with a default, standard, and safe control range, preventing equipment malfunction when other strategies fail and ensuring the system's basic availability. It adapts to usage patterns across different time periods, such as daytime, nighttime, late night, and peak hours, enabling automatic switching based on time without manual intervention. Furthermore, it automatically adjusts based on the frequency of control commands received within the same group, intelligently adapting to pedestrian density in real time. A higher number of received control commands indicates more microwave triggering, higher pedestrian density, and more frequent use, requiring an expanded lighting range; conversely, fewer commands result in a smaller range, truly achieving on-demand adjustment.

[0022] 5) This invention provides a lighting control system with infrared scanning and sensor linkage. By setting a lighting strategy module and a lighting customization module, users can either select a preset lighting strategy from the lighting strategy module to control the lighting fixtures accordingly to meet different lighting needs, or customize lighting needs through the lighting customization module to customize the lighting working strategy as needed to meet the user's personalized lighting needs.

[0023] 6) This invention provides a lighting control system with infrared scanning and sensor linkage. By setting up a sensor linkage module, the lighting can be controlled according to the operating status of the single lamp controller and the linkage relationship of the lighting, providing multiple control methods, effectively increasing the scope of application, and meeting the different control needs of users.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] [First Embodiment] like Figure 1-14 The image shows a lighting control system with infrared barcode scanning and sensor linkage provided in the first embodiment of the present invention, as shown below. Figure 1 As shown, the system provided in this embodiment includes: Lighting modules, such as Figure 3 As shown, the lighting module in this embodiment includes a lighting fixture connected to a driving power supply. A single-lamp controller is connected to the driving power supply to control the on / off state and adjust the output power of the driving power supply. Multiple single-lamp controllers are connected to a centralized controller. After receiving the lighting fixture data uploaded by the single-lamp controllers, the centralized controller controls the lighting fixtures accordingly based on the preset lighting strategy or custom lighting strategy uploaded by the single-lamp controllers. like Figure 2As shown, in this embodiment, the lamp 100 in the lamp module is an explosion-proof lamp, including an interconnected wiring cavity 101, an electrical cavity 102, and a light source cavity 103. By setting the lamp to include interconnected wiring cavities, electrical cavities, and light source cavities, the separate design can reduce thermal coupling and electromagnetic interference between different areas and lower the probability of fault chain reactions due to the different energy densities and protection methods of each cavity; at the same time, it can effectively prevent the propagation of explosions. If a cavity generates a spark or internal explosion due to an electrical fault, the independent cavity structure can prevent the flame from spreading to other cavities through the explosion-proof shell, avoiding pressure overlap and secondary explosions within the cavity; the wiring cavity 101 is connected to the drive power supply through built-in wiring, and the single lamp controller is set to... The light source is housed inside the electrical cavity 102 and the light source cavity 103. The light source is connected to the single lamp controller via a built-in antenna 1033. A power supply heat sink 1021 and a light source heat sink 1031 are located on the outside of the electrical cavity and the light source cavity, respectively. By setting the power supply heat sink and the light source heat sink on the outside of the electrical cavity and the light source heat sink on the outside of the light source cavity, the heat dissipation path is effectively separated. The heat from the light source cavity is conducted out through the outer light source heat sink, and the heat from the electrical cavity is dissipated through the ventilation structure of the outer power supply heat sink. This avoids the heat source from accumulating and causing the internal components to overheat. It also effectively prevents the heat from the light source from affecting the power supply and the temperature-sensitive devices such as the intelligent controller.

[0042] like Figure 3 As shown, this embodiment also includes an infrared microwave sensing module. The infrared microwave sensing module is connected to the driving power supply through a single lamp controller. The infrared microwave sensing module can analyze the motion state of the target object and determine whether there is a dynamically moving target, and distinguish between day and night by calibrating the ambient illuminance. Thus, the single lamp controller controls and adjusts the output power provided by the driving power supply to the lamp. like Figure 4 As shown, its specific working process is as follows: When the infrared microwave sensing module analyzes the motion state of the target object and determines whether there is a dynamically moving target: First, check if there are any dynamically moving targets: When no moving target is detected, the drive power supply is kept inactive by the single lamp controller. When a dynamically moving target is detected, the ambient illuminance value at that moment is then measured: If the ambient illuminance value is greater than the preset light sensing threshold, the infrared microwave sensing module will not send a sensing signal to the single lamp controller, and the single lamp controller will remain in its original state. If the ambient illuminance does not exceed the preset light sensing threshold, the infrared microwave sensing module sends a corresponding sensing signal to the single lamp controller, which then controls the corresponding action of the drive power supply.

[0043] like Figure 5As shown, the system mentioned in this embodiment is also equipped with an infrared barcode scanning module. The infrared barcode scanning module sends a parameter reading command for the corresponding lamp to the single lamp controller. After receiving the parameter reading command, the single lamp controller returns a unique code and device data corresponding to the lamp. The device data is uploaded to the service center in a timed or active manner for periodic status reporting and alarm management. The infrared barcode scanning module can also realize remote on / off control of the lamp and brightness adjustment.

[0044] By setting up an infrared barcode scanning module, not only are cost advantages achieved, but the data acquisition process is fundamentally restructured, realizing closed-loop management with on-site scanning and real-time data entry. This completely eliminates paper-based management, achieving data digitization. It removes the transcription step from paper to electronic, effectively avoiding the risk of data loss due to human error, document loss, or entry delays, ensuring the real-time nature, accuracy, and completeness of data. It also reduces the workload of single-lamp data acquisition and entry by more than 10 times, greatly improving project deployment and data initialization efficiency. Simultaneously, by combining the infrared barcode scanning terminal with the system's backend electronic map, specific lamps can be quickly located, allowing for a direct view of equipment distribution and status. Furthermore, the infrared barcode scanning module enables real-time visualization of construction progress, facilitating precise monitoring of on-site construction progress and achieving transparent and refined management of project progress. Installation quality is also traceable; each scanning operation records the operator, time, and location (GPS information), forming an unalterable electronic file. In case of later malfunctions, the installation process can be quickly traced back to the installation stage, clarifying responsibility and improving project quality.

[0045] In addition, the system provided in this embodiment is also equipped with a group control module. The group control module is connected to the lighting module to group the lighting fixtures as needed. According to the actual situation of the user, the module determines the individual lamp controllers corresponding to each lighting fixture in the same group, and forms a correspondence table with the unique code and device serial number of the individual lamp controllers corresponding to each lighting fixture. The correspondence table is then sent to the corresponding individual lamp controllers. When any individual lamp controller in the same group receives a control command, it sends the control command through the carrier channel in the form of group broadcast. When other individual lamp controllers in the same group receive the control command, they determine whether dimming is required based on their own device serial number and lamp control range value.

[0046] In this embodiment, the lighting control range value can be obtained in the following way: A) The lighting control range values ​​are pre-configured by the system; B) The lighting control range value can be automatically changed over time; C) The lighting control range value can be automatically adjusted by the individual lamp controller based on the number of control commands received by the same group of individual lamp controllers within a preset statistical sampling time period: When the number of times a single lamp controller in the same group receives control commands exceeds the preset number within a preset statistical sampling period, the single lamp controller will increase the lamp control range value. When the number of times the single lamp controller in the same group receives control commands within the preset statistical sampling time period does not exceed the preset number, the single lamp controller controls to reduce the lamp control range value; Within the preset valid window period: If the lighting control range value obtained by method B) does not exceed the lighting control range value obtained by method A), then the lighting control range value obtained by method A) shall be selected. If the lighting control range value obtained by method B) is greater than the lighting control range value obtained by method A), then the lighting control range value obtained by method B) shall be selected. When the time exceeds the preset effective window period, the lighting control range value obtained by method C) is selected.

[0047] The preset statistical sampling time period is used to count the number of control commands received by acquisition method C). It is a short period, such as 5 minutes or 10 minutes, to calculate statistics and determine whether the light control range needs to be increased or decreased. The preset effective window period is the effective window period for acquisition methods A) and B), which is a long period. For example, if the current time is between 17:00 and 20:30, the range value of the light controller can be selected between acquisition methods A) and B); if the current time is not between 17:00 and 20:30 (for example, 16:30 or 23:00), then acquisition method C) is used in automatic adaptation mode.

[0048] Because a single adjustment method cannot adapt to complex scenarios, dynamic pedestrian flow, environmental changes, and maintenance needs, this embodiment is divided into three categories, each with its own function, covering three major scenarios: fixed use, timed adaptation, and automatic adaptive optimization. Multiple adjustment methods are designed for complementary use. The purpose of this setup is to allow the lighting control range value to automatically switch to the optimal strategy under different scenarios, time periods, and usage frequencies, without wasting energy, without affecting the user experience, and intelligently adapting to changes in pedestrian flow. Based on pre-set system parameters, a default, standard, and safe control range is provided for the lighting fixtures, preventing equipment malfunction when other strategies are abnormal and ensuring the system's basic availability. Adapting to usage patterns during different time periods, such as daytime, nighttime, late night, and peak hours, allows for automatic switching based on time without manual intervention. Automatic adjustment based on the number of control commands received in the same group allows for real-time intelligent adaptation to pedestrian density. A higher number of received control commands indicates more microwave triggering, higher pedestrian density, and more frequent use, requiring an expanded lighting range; conversely, a lower number of commands results in a smaller range, truly achieving on-demand adjustment.

[0049] Preferably, in this embodiment, for a linearly arranged lighting environment, the lighting control range index value satisfies: m min ≤m≤m max ; wherein m is the lamp control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range; m min is the minimum boundary value of the lamp control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range, and satisfies: m min =t-c, and when (t-c)<a, the minimum boundary value m min =a; m max is the maximum boundary value of the lamp control range serial number value of the t-th individual lamp controller that receives the control instruction within the control range, and satisfies: m max =t+c, and when (t+c)>b, the maximum boundary value m max =b; wherein, in a linearly arranged lamp environment, a is the device serial number of the first individual lamp controller, b is the device serial number of the last individual lamp controller, c is the lamp control range value; t is the t-th individual lamp controller that receives the control instruction between a and b, and satisfies a≤t≤b.

[0050] For example, taking the lamp control range value c being 2 as an example, that is, the individual lamp controller corresponding to the current lamp lights up two adjacent lamps after receiving the control instruction for illustration: After the device serial numbers are issued to the inside of the individual lamp controllers, a correspondence relationship between the device serial numbers and the unique codes of the individual lamp controllers in the same group is formed, and the correspondence relationship is as Figure 6 shown. At this time, the device serial number of the first individual lamp controller is 01, and the device serial number of the last individual lamp controller is 10, that is, a=1, b=10; When the infrared microwave sensing module detects that a dynamic moving target exists, it triggers through microwaves to synchronously control the individual lamp controllers at adjacent positions; 1) When the individual lamp controller with the device serial number 01 (that is, t=1 at this time) is microwave-triggered and the lamp control range value c is 2, it will synchronously control the individual lamp controllers with device serial numbers 02 and 03 at the rear side, and the control schematic diagram is as Figure 7 shown; at this time: The minimum boundary value m min =t-c=1-2=-1<a, therefore the minimum boundary value m min =a=1; The maximum boundary value m max =t+c=1+2=3<b, therefore the maximum boundary value m max =3; Therefore, the lamp control range serial number value m of the first individual lamp controller that receives the control instruction within the control range satisfies: mmin ≤m≤m max , that is 1≤m≤3; therefore, the single lamp controllers with rear device sequence numbers 02 and 03 can be synchronously controlled; 2) When the microwave of the single lamp controller with device sequence number 03 (i.e., t=3 at this time) is triggered and the lamp control range value c is 2, the single lamp controllers of front side No. 01, No. 02 and rear side No. 04, No. 05 will be synchronously controlled, and the control schematic diagram is shown in Figure 8 as shown; at this time: Minimum boundary value m min =t-c=3-2=1=a, so the minimum boundary value m min = 1; Maximum boundary value m max =t+c=3+2=5<b, so the maximum boundary value m max =5; Therefore, the lamp control range sequence number value m of the 3rd single lamp controller that receives the control instruction within the control range satisfies: m min ≤m≤m max , that is 1≤m≤5; therefore, the single lamp controllers with front device sequence numbers 01 and 02 and rear device sequence numbers 04 and 05 can be synchronously controlled at this time; 3) When the microwave of the single lamp controller with device sequence number 10 is triggered and the lamp control range value c is 2, the single lamp controllers of front side No. 08 and No. 09 will be synchronously controlled, and the control schematic diagram is shown in Figure 9 as shown; at this time: Minimum boundary value m min =t-c=10-2=8>a, so the minimum boundary value m min = 8; Maximum boundary value m max =t+c=10+2=12>b, so the maximum boundary value m max =b=10; Therefore, the lamp control range sequence number value m of the 10th single lamp controller that receives the control instruction within the control range satisfies: m min ≤m≤m max , that is 8≤m≤10; therefore, the single lamp controllers with front device sequence numbers 08 and 09 can be synchronously controlled at this time; For the lighting fixture environment arranged in a matrix, by establishing a coordinate system, all single lamp controllers are placed in the first quadrant, and at this time the coordinate values of the lamp control range satisfy: x min ≤x≤x max ; y min ≤y≤y max ; where (x, y) is the lamp control range coordinate value of the i-th single lamp controller that receives the control instruction within the control range; The smallest coordinate in the coordinate system is (x min y min The maximum coordinate of the coordinate system is (x max y max ); The minimum boundary value of the lamp control range coordinates of the i-th lamp controller receiving the control command within the control range is (x1, y1); and satisfies: x1=x i -c; y1=y i -c; If x1 <x min Then x1 = x min If y1 <y min Then y1=y min ; The maximum boundary value of the lamp control range coordinates of the i-th lamp controller receiving the control command within the control range is (x2, y2); and satisfies: x2=x i +c; y2=y i +c; If x2>x max Then x2 = x max ;if y2>y max Then y2=y max ; And among them, (x) i y i ) represents the coordinates of the i-th single-lamp controller that received the control command, and c represents the lamp control range value.

[0051] For example, taking a lamp control range value c of 2 as an example, that is, the single lamp controller corresponding to the current lamp lights up two adjacent lamps after receiving a control command: After the position coordinates are sent to the individual lamp controller, a unique correspondence is formed between the position coordinates and the unique code of the individual lamp controller in the same group. The correspondence is as follows: Figure 10 As shown, the position coordinates of the first single-lamp controller are (1, 1), and the position coordinates of the last single-lamp controller are (10, 10), i.e., x min =1, y min =1, x max =10, y max =10; 1) such as Figure 11 As shown, when the coordinates of the microwave-triggered lamp controller satisfy x<2, y<2, the coordinates of the microwave-triggered lamp controller, that is, the coordinates of the i-th single lamp controller that receives the control command (x<2, y<2), are... i y i When ) is (1,1), Minimum boundary coordinates: x1=1-2=-1, y1=1-2=-1. Since all the lamp controllers are in the first quadrant and there is no single lamp controller at position (0,0), the negative coordinates and zero point are invalid. That is, the minimum boundary coordinates are (1,1). Maximum boundary coordinates: x2=1+2=3, y2=1+2=3, that is, the maximum boundary coordinates are (3, 3). Therefore, the coordinates (x3, y3) of the single-lamp controller within the control range satisfy: When x2≥x3≥x1 and y2≥y3≥y1, the lighting controllers within this control range will be synchronously controlled; otherwise, no action will be taken. The coordinates of the lighting controllers that will be subject to synchronous control, as calculated above, are: (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3); 2) such as Figure 12 As shown, when the coordinates of the microwave-triggered lamp controller satisfy x > 2 and y < 2, the coordinates of the microwave-triggered lamp controller, that is, the coordinates of the i-th single lamp controller that receives the control command (x i y i When ) is (3, 1), Minimum boundary coordinates: x1=3-2=1, y1=1-2=-1. Since all the lamp controllers are in the first quadrant and there is no single lamp controller at position (0,0), the negative coordinates and zero point are invalid. That is, the minimum boundary coordinates are (1,1). Maximum boundary coordinates: x2=3+2=5, y2=1+2=3, that is, the maximum boundary coordinates are (5, 3). Therefore, the coordinates (x3, y3) of the single-lamp controller within the control range satisfy: When x2≥x3≥x1 and y2≥y3≥y1, the lighting controllers within this control range will be synchronously controlled; otherwise, no action will be taken. The coordinates of the lighting controllers that will be subject to synchronous control, as calculated above, are: (1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,2), (3,3), (4,1), (4,2), (4,3), (5,1), (5,2), (5,3); 3) such as Figure 13 As shown, when the coordinates of the microwave-triggered lamp controller satisfy x < 2, y > 2, the coordinates of the microwave-triggered lamp controller, that is, the coordinates of the i-th single lamp controller that receives the control command (x i y i When ) is (1, 3), Minimum boundary coordinates: x1=1-2=-1, y1=3-2=1. Since all the lamp controllers are in the first quadrant and there is no single lamp controller at position (0,0), the negative coordinates and zero point are invalid. That is, the minimum boundary coordinates are (1,1). Maximum boundary coordinates: x2=1+2=3, y2=3+2=5, that is, the maximum boundary coordinates are (3, 5). Therefore, the coordinates (x3, y3) of the single-lamp controller within the control range satisfy: When x2≥x3≥x1 and y2≥y3≥y1, the lighting controllers within this control range will be synchronously controlled; otherwise, no action will be taken. The coordinates of the lighting controllers that will be subject to synchronous control, as calculated above, are: (1,1)(1,2), (1,4)(1,5), (2,1), (2,2), (2,3), (2,4), (2,5), (3,1), (3,2), (3,3), (3,4), (3,5); 4) such as Figure 14 As shown, when the coordinates of the microwave-triggered lamp controller satisfy x > 2 and y > 2, the coordinates of the microwave-triggered lamp controller, that is, the coordinates of the i-th single lamp controller that receives the control command (x i y i When ) is (3,3), Minimum boundary coordinates: x1=3-2=1, y1=3-2=1, that is, the minimum boundary coordinates are (1,1). Maximum boundary coordinates: x2=3+2=5, y2=3+2=5, that is, the maximum boundary coordinates at this time are (5, 5); Therefore, the coordinates (x3, y3) of the single-lamp controller within the control range satisfy: When x2≥x3≥x1 and y2≥y3≥y1, the lighting controllers within this control range will be synchronously controlled; otherwise, no action will be taken. The coordinates of the lighting controllers that will be subject to synchronous control, as calculated above, are: (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 4), (3, 5), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5); The system mentioned in this embodiment also includes a lighting strategy module, which has multiple preset lighting strategies. Users can select at least one of these lighting strategies as needed. The multiple preset lighting strategies in the lighting strategy module include at least sunrise and sunset lighting modes, motion-sensing lighting modes, timed control lighting modes, and strategy combination lighting modes, so that users can select preset lighting strategies from the lighting strategy module to control the lamps accordingly to meet different lighting needs.

[0052] The system mentioned in this embodiment also includes a lighting customization module. The lighting customization module supports users in customizing their lighting needs. Users can customize lighting working strategies as needed, so that users can also customize lighting needs through the lighting customization module and customize lighting working strategies as needed to meet their personalized lighting needs.

[0053] The energy consumption statistics module performs statistics on lighting electricity consumption, analyzes the electricity consumption data, and generates energy consumption reports through the system. The system mentioned in this embodiment is also equipped with a sensor linkage module. The sensor linkage module can control the lamps in a single device control mode, a multi-device control mode, or a linkage control mode. By setting up the sensor linkage module, the lamps can be controlled according to the operating status of the single lamp controller and the linkage relationship of the lamps, providing multiple control methods, effectively increasing the scope of application, and meeting the different control needs of users.

[0054] When the sensor linkage module adopts a single-device control mode, upon detecting a control command, it first determines the operating status of the single-lamp controller itself: If the operation is in automatic mode and no control command is sent, the lighting fixtures will be dimmed according to the preset lighting strategy; if a control command has been sent, only the delay period will be reset and no further control command will be sent. If the running status is manual, no action will be taken.

[0055] The single-device control mode has the following advantages: 1) High reliability and no single point of failure risk: It does not rely on the network or the centralized controller. As long as the single lamp controller itself is normal, it can work. It can still guarantee the lighting function in extreme environments (communication interruption). 2) Simple deployment and low cost: No wiring or networking is required, no additional equipment is needed, and a single lamp can be installed and used, making it suitable for small-scale, scattered lighting scenarios; 3) Fast response speed: Local processing of sensing signals triggers lamp action at the millimeter level, with no communication delay; 4) Easy to debug and maintain: The parameters of each lamp controller can be set independently, and troubleshooting and replacement will not affect other lamp controllers, resulting in low maintenance costs.

[0056] When the sensor linkage module adopts a multi-device control mode, The single-lamp controller first determines its own operating status: If the operation is in automatic mode and no control command is sent, the lighting fixtures will be dimmed according to the preset lighting strategy; if a control command has been sent, only the delay period will be reset and no further control command will be sent. If the running status is manual, no action will be taken; After the lighting controller finishes processing, the lighting data is uploaded to the central controller. The lighting fixture data should include at least the device serial number, sensing signal, delay period, and lighting fixture operating status data; After acquiring the lighting data uploaded by the individual lamp controller, the central controller randomly acquires the operating status of the lamps within the control range of the preset lighting strategy based on the binding relationship between the lamps and the preset lighting strategy. When the proportion of the acquired operating status as automatic is less than the preset threshold, the central controller does not issue control commands; otherwise, it issues control commands corresponding to the preset lighting strategy.

[0057] The centralized controller uses the percentage of light controllers in automatic mode as the basis for issuing group commands. If the percentage of automatic mode controllers is less than a preset threshold, it indicates that most controllers are operating in manual mode, and the system does not issue control commands. Conversely, if the percentage is higher, it indicates that most individual light controllers are operating in automatic mode, and the system issues control commands for the corresponding lighting strategy to achieve group linkage. The advantages of this setup are: firstly, after data is reported to the system, even if the devices are not under the same concentrator, the system can still schedule surrounding devices in real time; secondly, by randomly obtaining device status, compared to polling all lights, the communication message data between the centralized controller and individual light controllers is significantly reduced, lowering the bus communication load and making it suitable for large-scale lighting network scenarios; furthermore, using lighting strategy combined with light binding relationships as the grouping basis results in clear group divisions and controllable linkage range.

[0058] The advantages of using a multi-device control mode are as follows: 1) Enables regional-level linkage control: It can achieve the effect of "lighting up when someone comes". After a single lamp senses a moving target, it transmits the signal to the concentrator. The concentrator coordinates and issues group control commands to achieve synchronous lighting. 2) Unified operation and maintenance and batch configuration: The concentrator can modify the parameters of the entire group of lights in batches (such as sensing range, light sensing threshold, etc.) without the need for individual lamp debugging, which greatly reduces the workload of operation and maintenance. 3) Balancing centralized control and local operation: Even if the concentrator fails, a single lamp can still operate independently in local mode (such as the single device control mode mentioned above).

[0059] When the sensor linkage module adopts the linkage control mode, When the infrared microwave sensing module detects a dynamically moving target, the single-lamp controller connected to the infrared microwave sensing module first determines the operating status of the single-lamp controller itself: If the single-lamp controller is determined to be in manual mode, then no control is performed. If the single-lamp controller is determined to be in automatic mode, then the dimming control of the lamps is performed through the single-lamp controller according to the current preset lighting strategy. After the control is completed, the lamp data is uploaded to the central controller through the individual lamp controller; After receiving the uploaded lighting data, the centralized controller first determines whether it needs to control the lighting within the current control range of the centralized controller based on the binding policy configured on the platform. The binding policy configured on the platform is a linkage rule that runs on the centralized controller or cloud platform. It will only be executed after the lighting data of individual light controllers is reported to the centralized controller. It is not a parameter of the individual light controller itself, but defines the linkage relationship between lights and between areas.

[0060] If control is required, it will be controlled according to the preset lighting strategy, and then the lighting data will be uploaded to the server. After receiving the uploaded lighting data, the server first queries the database to check the linkage relationship between the lighting fixture and other lighting fixtures under the same central controller. If a linkage relationship exists, the server will send the preset lighting strategy to the corresponding central controller for execution; otherwise, the server will not process it.

[0061] The advantages of using a linkage control mode are as follows: 1) Adopting a unified network-wide management system that supports large-scale deployment: It can uniformly monitor all single-lamp controllers at the city and park levels, and view online status, fault alarms, and energy consumption data in real time, thereby realizing digital management of smart lighting; 2) Implement hierarchical control with clear permissions: The platform can set hierarchical permissions for different regions and devices to achieve multi-level management; 3) Fault alarm and asset management: The platform can monitor lamp failures, communication interruptions and other anomalies in real time, automatically generate alarms and work orders, realize preventive maintenance, extend equipment life and reduce operation and maintenance costs.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
