Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and in particular to an automatic positioning lamp and a lighting control system. Background Art

[0002] With the development of modern society, people are increasingly aware of the importance of lighting in their lives. This is especially true in places with high lighting requirements, such as museums, art galleries, commercial exhibition centers, airports, and high-speed rail stations, where the demand for precise lighting control (switching and dimming) is becoming increasingly high. The existing technologies often offer the following technical solutions:

[0003] 1. Through loop control

[0004] That is, several lamps are connected in parallel or series in a circuit, and switches and dimmers are added to the circuit to control the lighting. This solution is relatively common and relatively simple to install. It can realize the simultaneous control of the switching or dimming of several lamps. However, if this solution is used to control each lamp individually in a large lighting project, the installation and wiring work is very large and the cost is very high. Moreover, since the lamps and control switches and dimmers are separate during use, the user is required to clearly understand the one-to-one correspondence between each lamp and each control switch and dimmer, which is obviously unrealistic. Therefore, installing an independent circuit for each lamp to control it is generally not suitable for many lighting applications.

[0005] 2. Controlled by switches and dimming units on lamps

[0006] That is, each lamp is equipped with an independent switch and dimmer for control. This solution allows for independent switching and dimming of each lamp, while leaving other lamps unaffected. Compared to loop control, this solution achieves single-lamp control without the high engineering workload and installation costs, and does not require the user to clearly understand the correspondence between lamps and switches. It is also a common solution for applications that currently require single-lamp dimming. However, a serious disadvantage of this solution is that after the lamps are installed, if the user needs to adjust the lighting environment, they must climb to the height where the lamps are installed to operate each lamp, which is very inconvenient. This is especially true for places with a large number of lamps and frequently changing lighting environments, such as museums, art galleries, and commercial exhibition centers where exhibitions are frequently changed. This greatly increases the user's workload and operating costs. Moreover, if the lamps are installed at high heights or in difficult-to-reach locations, it can even increase the danger of operation.

[0007] 3. Digital Addressable Lighting Interface System Dimming

[0008] Digital addressable lighting interface systems include DALI (Digital Addressable Lighting Interface) and DMX. For example, DALI is a data transmission protocol that defines the communication method between electronic ballasts and device controllers. Its basic system structure connects a DALI ballast, which combines a combination switch and dimming control, to a two-core control cable via a DALI interface. The system addresses each ballast individually, and the system identifies and controls each lamp based on the address. However, this latest intelligent lighting control system has several significant problems:

[0009] 1. It requires the use of two separate control lines (or two-core wires), requiring the main power line to be isolated from the control line, and the voltage drop on the control line to be no more than 2V when the current is 250mA and the line length is 300 meters. This brings great inconvenience to the system installation, especially if this system is needed in an existing project, which requires laying new control lines, which is very difficult.

[0010] 2. The debugging of the DALI system is very complicated and requires professional personnel. In particular, if a lamp is damaged, even if a new one is replaced, special equipment is needed to set its parameters. Otherwise, the system management cannot be entered. This is also difficult for ordinary users to complete independently.

[0011] 3. The addressing of DALI ballasts is completed during system debugging. After each debugging, the address of any ballast on the control line is uncertain. Therefore, when a ballast in the system fails and needs to be replaced, it is not a simple replacement. Instead, the address of the new ballast must be the same as the address of the replaced ballast. Currently, the ballast address must be re-addressed with the help of special debugging equipment, otherwise address conflicts will occur. A very strict management method is required to ensure its operation and maintenance, otherwise it is likely to cause system disorder.

[0012] 4. When resetting the system, such as when the system crashes, the equipment is updated, or even just one new lamp is added to the system, all lamps need to be re-addressed and re-addressed; because the DALI address of each lamp is randomly generated, all the original settings (such as groups, scene modes, timing settings, etc.) and data will be completely messed up and need to be reset, that is, the entire project needs to be re-debugged.

[0013] 5. Users usually control lamps through a central control system, which requires users to have high professional knowledge. Moreover, since the on-site lighting effect cannot be directly observed, it requires the cooperation of multiple people or auxiliary equipment to accurately configure the lighting, which increases labor and equipment costs.

[0014] 4. Wireless Lighting Control System

[0015] Lighting control systems based on Bluetooth mesh, ZigBee, and other radio frequency communication solutions are increasingly being used. These wireless lighting control systems eliminate the need for signal wiring and offer greater convenience and flexibility. However, due to their wireless nature, the systems are unable to confirm the specific location of the controlled lighting devices, complicating management and maintenance. While suitable for small-scale applications, comprehensive lighting control in large buildings requires complex and stringent management measures, significantly increasing management costs.

[0016] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0037] The lighting control system includes three positioning and communication base stations, and the positioning and communication base stations are not arranged in a straight line; the central control server calculates the distance between the automatic positioning lamp and each positioning and communication base station, and then measures the relative two-dimensional coordinate data between the automatic positioning lamp and each positioning and communication base station, and then calculates the accurate two-dimensional coordinate data of the automatic positioning lamp in the building space in combination with the building space drawings or user-defined equipment layout rules; or

[0038] The lighting control system includes two positioning and communication base stations. The central control server calculates the distance between the automatic positioning lamp and each positioning and communication base station, and then measures the relative one-dimensional coordinate data between the automatic positioning lamp and each positioning and communication base station. Then, combined with the building space drawings or user-defined equipment layout rules, the central control server calculates the accurate one-dimensional coordinate data of the automatic positioning lamp in the building space.

[0039] According to the lighting control system of the present invention, the central control server adopts TDOA positioning technology to calculate the distance and / or angle between the automatic positioning lamp and each of the positioning and communication base stations, and then measures the relative position between the automatic positioning lamp and each of the positioning and communication base stations, and then combines the building space drawings or user-defined equipment layout rules to calculate the exact position of the automatic positioning lamp in the building space.

[0040] According to the lighting control system of the present invention, the lighting control system further comprises at least one automatic positioning sensor, the automatic positioning sensor communicating with the central control server via the positioning and communication base station;

The central control server calculates the distance between the automatic positioning sensor and each positioning and communication base station, measures the relative position between the automatic positioning sensor and each positioning and communication base station, and then calculates the exact position of the automatic positioning sensor in the building space in combination with the building space drawings or user-defined equipment layout rules.

[0043] According to the lighting control system of the present invention, the database of the central control server pre-stores at least a device table, a group table, a system attribute table and a building table;

[0044] The device table records device attributes and status data of each device in the lighting control system, wherein the device attributes and status data include the type of the device, the first device identification number, the current location coordinates and / or working status information, and the device at least includes the automatic positioning lamp;

[0045] The system attribute table records system attribute data, and the system attribute data at least includes the first system code of the system;

[0046] The building table records the building space drawings, as well as the positioning index information of each positioning and communication base station in the building space drawings and the device layout rules defined by the user;

[0047] The central control server is configured to generate a second control instruction based on the first control instruction, where the second control instruction includes the first system code, the first device identification number of the automatically positioned lamp to be controlled, an operation command, and operation parameters, and send the second control instruction to the automatically positioned lamp via the positioning and communication base station;

[0048] The automatic positioning lamp includes the first positioning and communication module, the first multi-channel controller module, and the light source;

[0049] The first positioning and communication module is configured to receive the second control instruction forwarded by the positioning and communication base station;

[0050] The first multi-channel controller module further comprises:

[0051] A storage unit for storing a second device identification number of the lamp, a recent operating status, and / or a second system code of the lighting control system to which it is connected. The second device identification number is unique and fixed in the storage unit, cannot be modified, and will not be cleared due to a device reset; and / or

[0052] A reset switch, used to clear various setting data in the storage unit; and / or

[0053] A multi-channel control unit having an output for controlling the automatic positioning lamp and an input for providing feedback on the working status of the device; and / or

[0054] Indicator lights are used to indicate the device's working status, system access status, and / or positioning status;

[0055] After the first positioning and communication module in the automatic positioning lamp receives the second control instruction, the first multi-channel controller module compares the first system code and the first device identification number in the second control instruction with the second system code and the second device identification number in the storage unit; if they are consistent, the multi-channel control unit converts the second control instruction into a corresponding control signal and controls the light source to operate according to the operation command and the operation parameters;

[0056] After the second control instruction is successfully operated, the first multi-channel controller module records the working status after the operation in the storage unit and returns result feedback data to the central control server.

[0057] According to the lighting control system of the present invention, the automatic positioning lamp begins to initialize after being powered on, and the automatic positioning lamp reads the second system code and the second device identification number of the automatic positioning lamp from the storage unit in the first multi-channel controller module;

[0058] The first positioning and communication module automatically scans the current working environment to determine whether there is a signal from the positioning and communication base station:

[0059] If the first positioning and communication module detects the signal of the positioning and communication base station, it automatically establishes a link and sends the second system code and the second device identification number to the central control server. The central control server compares the second system code and the second device identification number with the pre-stored first system code and the first device identification number to see if they are the same;

[0060] If the second system code is the same as the first system code, and the first device identification number of the automatic positioning lamp is recorded in the device table, the central control server queries the working status information in the device table, and then the central control server sends the second control instruction to the automatic positioning lamp via the positioning and communication base station. After the first positioning and communication module of the automatic positioning lamp receives the second control instruction from the central control server, the multi-channel control unit of the first multi-channel controller module converts the second control instruction into a control signal to control the light source to operate;

[0061] If the second system code is the same as the first system code, but the first device identification number of the automatic positioning lamp is not recorded in the device table, the central control server sends a first new prompt instruction to the automatic positioning lamp via the positioning and communication base station. After the automatic positioning lamp receives the first new prompt instruction through the first positioning and communication module, the multi-channel control unit in the first multi-channel controller module converts the first new prompt instruction into a control signal to control the light source to operate; and the central control server lists the attribute information of the newly added automatic positioning lamp in the user interface of the operating terminal device, and after receiving the user confirmation instruction, adds the attribute information of the newly added automatic positioning lamp to the device table and the device positioning data table of the database. The automatic positioning lamp is connected to the lighting control system management and operates in normal mode.

[0062] If the second system code of the automatic positioning lamp is a null value, the central control server sends a second new prompt instruction to the automatic positioning lamp via the positioning and communication base station. After the automatic positioning lamp receives the second new prompt instruction through the first positioning and communication module, the multi-channel control unit in the first multi-channel controller module converts the second new prompt instruction into a control signal to control the light source to work; the central control server lists the attribute information of the newly added automatic positioning lamp on the operating terminal device, and after receiving the user confirmation instruction, adds it to the device table and the device positioning data table of the database. The second new prompt instruction carries the first system code. After the automatic positioning lamp receives the second new prompt instruction, it records the first system code in the storage unit of the first multi-channel controller module. The automatic positioning lamp is connected to the system management and works in normal mode;

[0063] If the second system code of the automatically positioned lamp is not a null value and is different from the scanned first system code, the automatically positioned lamp rescans until the scanned first and second system codes are the same, and then is connected to the lighting control system management according to the above rules; or after repeated scanning for multiple times and still no consistent system code is found, the scanning is stopped, and the indicator light prompts according to the predetermined rules; after the reset switch in the first multi-channel controller module of the automatically positioned lamp receives a long press instruction, the second system code data of the storage unit of the device is cleared, and then the device is rescanned and connected to the lighting control system management according to the above process, and then operates in normal mode;

[0064] If the first positioning and communication module does not find the signal of the positioning and communication base station after multiple scans, the automatic positioning lamp outputs the most recent working status recorded in the storage unit of the device.

[0065] According to the lighting control system of the present invention, when the lighting control system is initialized, a super user is set to be generated. The super user has global management authority over the lighting control system and can manage all management areas or devices of the system; the super user can add at least one ordinary user and authorize part of the management areas or devices for the ordinary user; the ordinary user can add at least one sub-user and authorize part of the management areas or devices for the sub-user to which the sub-user has authority, and each upper-level sub-user can add his own lower-level sub-user and authorize part of the management areas or devices for which the sub-user has authority, forming multiple upper-lower and lower-level control relationships, and the multiple upper-lower and lower-level control relationships are recorded in the user function table of the database of the central control server; or

[0066] The operation terminal device sends a single lamp control instruction carrying a first device identification number to the central control server through the positioning and communication base station. The central control server selects an automatic positioning lamp corresponding to the first device identification number from the device table according to the single lamp control instruction and controls the lamp;

[0067] The operation terminal device sends a regional lighting control instruction carrying a regional range to the central control server through the positioning and communication base station. The central control server selects at least one automatic positioning lighting fixture whose positioning coordinates are within the regional range from the device table according to the regional lighting control instruction, controls the lighting fixture, generates a corresponding regional grouping attribute, and records the attribute in the grouping table.

[0068] The operating terminal device sends a group lamp control instruction carrying multiple first device identification numbers to the central control server through the positioning and communication base station. The central control server filters out multiple automatic positioning lamps corresponding to the multiple first device identification numbers carried from the device table according to the group lamp control instruction, and generates corresponding logical grouping attributes for them and records them in the group table.

[0069] The lighting control system of the present invention includes automatic positioning lamps, a central control server, a positioning and communication base station and an operating terminal device. The automatic positioning lamps include a first positioning and communication module, a first multi-channel controller module and a light source. The present invention utilizes indoor precise positioning technology to enable the automatic positioning lamps to automatically connect to the lighting control system for management. The automatic positioning lamps communicate with the positioning and communication base station. The central control server calculates the distance between the lamps and each base station, measures the relative position between the lamps and each base station, and obtains the accurate position of the lamps in the building space in combination with the building space drawings. The device position can also be graphically displayed on the operating terminal device, which not only enables automatic positioning of lamps and other equipment, but also makes system management more intuitive, convenient and easy to operate. In addition, the operating terminal device sends a first control instruction to the central control server, and the central control server generates a second control instruction based on the first control instruction, and sends the second control instruction to the automatic positioning lamp via the positioning and communication base station. After the first positioning and communication module receives the second control instruction from the positioning and communication base station, the first multi-channel controller module converts the second control instruction into a corresponding control signal to control the light source to operate. The lighting control system of the present invention boasts a simple structure and is easy to implement. It eliminates the need for additional control signal wiring, significantly reducing the cost of system construction or upgrades. Overall, the present invention offers the advantages of automatic equipment positioning, a simple structure, easy installation and maintenance, convenient operation, economical cost, and flexibility. It is particularly suitable for systematic lighting control and management in venues such as museums, art galleries, and commercial exhibition centers, where lighting equipment frequently needs to be relocated.

The lighting control system 100 also includes at least one automatic positioning lamp 10, at least one central control server 20, at least one positioning and communication base station 30 and at least one operation terminal device 40. The positioning and communication base station 30 and the operation terminal device 40 are respectively connected to the central control server 20 for communication. The operation terminal device 40 sends a first control instruction to the central control server 20. The central control server 20 generates a second control instruction according to the first control instruction, and sends the second control instruction to the automatic positioning lamp 10 via the positioning and communication base station 30. The database of the central control server 20 pre-stores architectural space drawings of the building space, and the architectural space drawings are preset with the coordinate position of the positioning and communication base station 30.

[0081] Figure 2 3 is a structural diagram of an automatic positioning lamp provided by an embodiment of the present invention. The automatic positioning lamp 10 mainly includes at least one first positioning and communication module 11, at least one first multi-channel controller module 12, and at least one light source 13.

[0082] The first positioning and communication module 11 is used to communicate with each positioning and communication base station 30 when the automatic positioning lamp 10 is connected to the lighting control system 100. The central control server 20 calculates the distance between the automatic positioning lamp 10 and each positioning and communication base station 30 to measure the relative position between the automatic positioning lamp 10 and each positioning and communication base station 30. Then, based on the architectural space drawings or user-defined equipment layout rules, it calculates the exact position of the automatic positioning lamp 10 in the building space and graphically displays the exact position on the operation terminal device 40. The central control server 20 is also used to receive second control instructions forwarded by the positioning and communication base station 30.

That is, the first positioning and communication module 11 and / or the first multi-channel controller module 12 are separate and independent of the automatic positioning lamp 10. This allows for integration with common lamps, allowing existing common lamps to be incorporated into the lighting control system 100, facilitating the upgrade and unified control of completed lighting projects. This modular component solution also allows for the rapid upgrading of existing common lamps that use wired signal control for switching and dimming, integrating them into the lighting control system 100 and reducing retrofit costs.

The positioning and communication base station 30 and the operation terminal device 40 are respectively connected to the central control server 20 for communication, and the automatic positioning lamp 10 communicates with the central control server 20 through the positioning and communication base station 30.

[0093] The operation terminal device 40 is used to send the first control instruction to the central control server 20. The operation terminal device 40 includes but is not limited to a computer, a smart phone, a smart panel, a tablet computer, etc.

[0094] The central control server 20 is the data center of the lighting control system 100 and is responsible for receiving and transmitting positioning and operating data of all devices in the system, performing comprehensive calculations, transmitting instructions, recording data, and providing services and data interfaces to users. Preferably, the central control server 20 is configured to generate a second control instruction based on the first control instruction and transmit the second control instruction to the automatically positioned luminaire 10 via the positioning and communication base station 30. The central control server 20 also has a database pre-stored with architectural drawings of the building space in which the central control server 20 is located, with the coordinates of the positioning and communication base station 30 pre-set in the drawings.

[0095] The positioning and communication base station 30 is configured to transmit the second control instruction to the automatic positioning lamp 10. The automatic positioning lamp 10, the automatic positioning sensor 50, and other devices communicate with the central control server 20 via the positioning and communication base station 30. The second control instruction from the central control server 20 is transmitted to the automatic positioning lamp 10, the automatic positioning sensor 50, and other devices via the positioning and communication base station 30.

[0096] The automatic positioning lamp 10 can communicate with the positioning and communication base station 30. The automatic positioning lamp 10 mainly includes a first positioning and communication module 11, a first multi-channel controller module 12 and a light source body 13.

[0097] The first positioning and communication module 11 is used to communicate with each positioning and communication base station 30 when the automatic positioning luminaire 10 is connected to the lighting control system 100. The central control server 20 calculates the distance between the automatic positioning luminaire 10 and each positioning and communication base station 30 to measure the relative position between the automatic positioning luminaire 10 and each positioning and communication base station 30. It then calculates the exact position of the automatic positioning luminaire 10 in the building space based on the building space drawings or user-defined equipment layout rules. The central control server 20 is also used to receive second control instructions forwarded by the positioning and communication base station 30.

[0098] The first multi-channel controller module 12 is used to convert the second control instruction into a corresponding control signal to control the light source 13 to operate.

[0099] The light source 13 is used to provide lighting for the building space according to the control signal.

[0100] Preferably, the lighting control system 100 includes at least four positioning and communication base stations 30, each preferably arranged on a different plane within the building space. The central control server 20 calculates the distance between the automatically positioned luminaire 10 and each positioning and communication base station 30, and then measures the relative three-dimensional coordinate data between the automatically positioned luminaire 10 and each positioning and communication base station 30. This data is then combined with the building space drawings or user-defined equipment layout rules to calculate the accurate three-dimensional coordinate data of the automatically positioned luminaire 10 within the building space.

[0101] In actual implementation, if the data of the positioning and communication base station 30 is reduced, the two-dimensional positioning coordinates or the relative linear one-dimensional positioning coordinates of the automatic positioning lamp 10 can also be obtained through algorithm optimization, both of which are variations of the present invention, as follows:

[0102] Preferably, the lighting control system 100 includes three positioning and communication base stations 30, and the positioning and communication base stations 30 are not arranged in a straight line; the central control server 20 calculates the distance between the automatic positioning lamp 10 and each positioning and communication base station 30, and then measures the relative two-dimensional coordinate data between the automatic positioning lamp 10 and each positioning and communication base station 30, and then combines the building space drawings or user-defined equipment layout rules to calculate the accurate two-dimensional coordinate data of the automatic positioning lamp 10 in the building space.

[0103] Preferably, the lighting control system 100 includes two of the positioning and communication base stations 30; the central control server 20 calculates the distance between the automatic positioning lamp 10 and each positioning and communication base station 30, and then measures the relative one-dimensional coordinate data between the automatic positioning lamp 10 and each positioning and communication base station 30, and then combines the architectural space drawings or user-defined equipment layout rules to calculate the accurate one-dimensional coordinate data of the automatic positioning lamp 10 in the architectural space.

[0104] Preferably, the central control server 20 adopts TDOA (Time difference of Arrival) positioning technology, and calculates the distance and / or angle between the automatic positioning lamp 10 and each positioning and communication base station 30, thereby measuring the relative position between the automatic positioning lamp 10 and each positioning and communication base station 30, and then calculates the exact position of the automatic positioning lamp 10 in the building space in combination with the building space drawings or user-defined equipment layout rules. The accurate position of the automatic positioning lamp 10 includes accurate three-dimensional coordinate data, accurate two-dimensional coordinate data and accurate one-dimensional coordinate data.

[0105] Preferably, the positioning and communication module communicates with the central control server 20 via a wireless (WIFI) or wired (Ethernet) network via a universal network.

[0106] Preferably, the operation terminal device 40 and the central control server 20 perform data communication via a universal network via wireless (WIFI) or wired (Ethernet).

[0107] Preferably, the lighting control system 100 may further include at least one automatic positioning sensor 50, such as Figure 3 As shown, the automatic positioning sensor 50 communicates with the central control server 20 through the positioning and communication base station 30.

[0108] The automatic positioning sensor 50 mainly includes a second positioning and communication module 51, a second multi-channel controller module 52, and a sensor module 53. The second positioning and communication module 51 and the second multi-channel controller module 52 of the automatic positioning sensor 50 are consistent with the first positioning and communication module 11 and the first multi-channel controller module 12 of the automatic positioning lamp 10, that is, their structure and operating principles are the same.

[0109] The second positioning and communication module 51 is used to communicate with each positioning and communication base station 30 when the automatic positioning sensor 50 is connected to the lighting control system 100. The central control server 20 calculates the distance between the automatic positioning sensor 50 and each positioning and communication base station 30, measures the relative position between the automatic positioning sensor 50 and each positioning and communication base station 30, and then calculates the exact position of the automatic positioning sensor 50 in the building space in combination with the building space drawings or user-defined equipment layout rules.

[0110] Preferably, the automatic positioning sensor 50 can detect the presence of people and illumination conditions in the area where it is located, and provide conditional data for the automatic intelligent control of the lighting control system 100. The control signal includes automatic sensing condition parameters, and the sensor module 53 works according to the automatic sensing condition parameters.

[0111] When the sensor module 53 detects that there is no person in the predetermined area, the output of each automatic positioning lamp 10 in the area is reduced or turned off, for example, entering an energy-saving state;

[0112] When the sensor module 53 detects the presence of a person in the area, it increases the output of or turns on each of the automatic positioning lamps 10 in the area; or

[0113] When the sensor module 53 detects that the light in the area exceeds a predetermined illumination threshold, such as when there is sufficient natural light, each automatic positioning lamp 10 in the area is reduced in output or turned off;

[0114] When the sensor module 53 detects that the light in the area does not exceed the illumination threshold, such as in rainy weather or when there is insufficient natural light at night, the output of each automatic positioning lamp 10 in the area is increased or turned on.

[0115] It should be pointed out that the above content only cites several application examples of the automatic positioning sensor 50. The actual application of the automatic positioning sensor 50 may obviously be more flexible and rich.

[0116] The automatic positioning sensor 50 is actually an input device. The automatic positioning sensor 50 of the present invention primarily involves accessing the lighting control system 100 (using the same process as the automatic positioning lamps 10) and collecting system operating environment data. For example, it senses the presence of people and the illumination level of a space. The system operating environment data is then transmitted to the central control server 20. Based on the received system operating environment data, the central control server 20 combines user-defined conditions (such as certain thresholds) and response strategies to generate relevant control instructions to operate certain automatic positioning lamps 10.

[0117] The automatic positioning sensor 50 is a work-end device and is not an essential device for the lighting control system 100. In actual applications, the automatic positioning sensor 50 may be configured or not configured according to usage requirements.

[0118] The present invention can automatically locate lamps 10 based on precise positioning technology, and the control module can automatically construct a lighting control system for the spatial layout diagram of lighting equipment according to the lamp positioning data. Specifically, the present invention provides an automatically positioned lamp 10 and a lighting control system 100, which does not require additional laying of control signal lines. The automatically positioned lamp 10 communicates with the positioning and communication base station 30, and the central control server 20 measures the relative position between the automatically positioned lamp 10 and each positioning and communication base station 30 by calculating the distance between the automatically positioned lamp 10 and each positioning and communication base station 30, and obtains the accurate position of the automatically positioned lamp 10 in the building space in combination with the building space drawings; and the central control server 20 transmits the control instructions of the operating terminal device 40 to the automatically positioned lamp 10 through the positioning and communication base station 30 to the automatically positioned lamp 10, and can perform dimming control of a single lamp or a group of automatically positioned lamps 10, with the advantages of simple structure, easy installation, easy debugging, intuitive and convenient, easy operation, stable performance, etc. It also makes the entire lighting system easy to maintain, economical in cost, flexible and convenient for engineering applications of various sizes, and is particularly suitable for systematic control and management of lighting in places such as museums, art galleries, and commercial exhibition centers where lighting equipment often needs to be moved.

[0119] Preferably, the database of the central control server 20 pre-stores at least a device table, a group table, a system attribute table, and a building table.

[0120] The device table records the device attributes and status data of each device in the lighting control system 100. The device attributes and status data include the type of device, the first device identification number (the first device identification number is unique), the current positioning coordinates and / or working status information. The device includes at least an automatic positioning lamp 10.

[0121] The system attribute table records system attribute data, and the system attribute data at least includes the first system code of the system, and the first system code is unique.

[0122] The building table records the building space drawings, the positioning index information of each positioning and communication base station 30 in the building space drawings, and the device layout rules defined by the user.

[0123] The central control server 20 is used to generate a second control instruction based on the first control instruction. The second control instruction includes a first system code, a first device identification number of the automatic positioning lamp 10 to be controlled, an operation command and an operation parameter, and sends the second control instruction to the automatic positioning lamp 10 via the positioning and communication base station 30.

[0124] The automatic positioning lamp 10 mainly includes a first positioning and communication module 11 , a first multi-channel controller module 12 , and a light source 13 .

[0125] The first positioning and communication module 11 is configured to receive a second control instruction transmitted from the positioning and communication base station 30 .

[0126] like Figure 4 As shown, the first multi-channel controller module 12 further mainly includes a storage unit 121, a reset switch 122, a multi-channel control unit 123 and / or an indicator light 124, wherein:

[0127] The storage unit 121 is used to store the second device identification number of the lamp, its most recent operating status, and / or the second system code of the connected lighting control system 100. Specifically, the second device identification number is unique and fixed in the storage unit 121. It is typically written at the factory and cannot be modified or cleared by a device reset. The second system code is received from the management system when the device is added to the management system.

[0128] The reset switch 122 is used to clear various setting data in the storage unit 121 and is used to clear the original setting data before the device is connected to a new lighting control system 100.

[0129] The multi-channel control unit 123 is an output terminal for controlling the automatic positioning lamp 10 and an input terminal for providing feedback on the device's operating status. For example, the multi-channel control unit 123 can be used to turn the automatic positioning lamp 10 on and off, adjust the brightness, color temperature, color, and illumination direction. The functions of the multi-channel control unit 123 of the multi-channel controller module of different intelligent working end devices vary slightly depending on the control requirements of the device.

[0130] The indicator light 124 is used to indicate the device's operating status, system access status, and / or positioning status. For example, when the device is scanning the surrounding system signal environment, the indicator light flashes slowly in blue; when the device is connected to the lighting control system 100 but is automatically resetting its positioning or initializing system data, the indicator light flashes rapidly in blue; when the device is connected to the lighting control system 100 and is operating normally according to system instructions, the indicator light is off; if there is a device failure, such as a damage to the light source of the automatic positioning lamp 10, the indicator light flashes red.

[0131] After the first positioning and communication module 11 in the automatic positioning lamp 10 receives the second control instruction, the first multi-channel controller module 12 compares the first system code and first device identification number in the second control instruction with the second system code and second device identification number in the storage unit 121. If they match, the multi-channel control unit 123 converts the second control instruction into a corresponding control signal and controls the light source 13 to operate according to the operation command and operating parameters.

[0132] After the second control instruction is successfully executed, the first multi-channel controller module 12 records the working status after the operation in the storage unit 121 and returns result feedback data to the central control server 20 .

[0133] It should be noted that the second multi-channel controller module 52 of the automatic positioning sensor 50 and the first positioning and communication module 11 of the automatic positioning lamp 10 have the same structure and working principle, which will not be described again to avoid repetition.

[0134] The present invention utilizes indoor precise positioning technology, and through system code, device identification number and database information technology, enables lighting equipment to be automatically connected to the lighting control system 100 for management, and combined with imported architectural space drawings, the device location can be reflected in the graphical interface, making system management more intuitive, convenient, easy to operate, and more operator-friendly, without the need for special technical training, saving operating costs; multi-level user authority setting, management authorization scheme by area; control instructions are in the form of a combination of system code, device identification number, operation command, and operation parameters, so that the scheme can be quickly upgraded to various existing ordinary lamps that use wired signals to control switches and dimming.

[0135] In order to better understand the present invention, the working principle and process of the lighting control system 100 in the preferred embodiment are described below:

[0136] like Figure 6 This is a schematic diagram of the application of the lighting control system 100 in building lighting. As shown in the figure, the building is already covered by a general network, which provides basic data communication for the central control server 20, the positioning and communication base station 30 and various operating terminal devices 40.

[0137] 1. Description of the basic database architecture of the central control server 20.

[0138] 1. Device table: records the type of each device in the lighting control system 100 (e.g., automatic positioning lamp 10, automatic positioning sensor 50, control panel, positioning and communication base station 30, etc.), each first device identification number (the first device identification number is unique in the lighting control system 100), the current positioning coordinates of each device, and the working status information of each device, including the current working status (e.g., switch status, dimming level, etc.).

[0139] 2. Grouping table: records device grouping information, such as grouping type (regional group or logical group, etc.), group name, device identification number within the group, etc.

[0140] 3. Scenario mode table: records the data of the equipment working status combination, such as the dimming level of each group or each lamp.

[0141] 4. Control object table: records the control objects and control function setting data of various control devices, such as the automatic positioning sensor 50.

[0142] 5. Scheduled task table: records preset equipment working status and planned start time or calendar data, etc.

[0143] 6. Timing task table: records the dynamic sequence data of the working status of preset equipment, etc.

[0144] 7. Control logic table: records the logical relationship of various control conditions, etc.;

[0145] 8. Equipment positioning data table: records the current and historical positioning data of each device in the lighting control system 100;

[0146] 9. User function table: records users and their respective function authority data, etc.;

[0147] 10. Space drawings and positioning index table: records the architectural space drawings of the space where the lighting control system 100 and the equipment are located, as well as the positioning index information of each positioning and communication base station 30 in the architectural space drawings.

[0148] 11. System attribute table: records system attribute data, including at least the first system code of the system, which is unique. Preferably, the system attribute data includes building name, geographical location, system code, system time, etc.

[0149] 2. Instructions for initial system settings:

[0150] like Figure 5 and Figure 6 As shown, the positioning and communication base station 30 hardware equipment is installed in the building space, and the central control server 20, the positioning and communication base station 30, and the operation terminal device 40 are connected to the same universal network;

[0151] The user interface of the operating terminal device 40 automatically connects to the central control server 20 and initializes user data, such as setting administrators and users with different authority levels.

[0152] Import the architectural space drawing into the user interface of the operating terminal device 40, and set the position index of the installed positioning and communication base station 30 in the architectural space drawing. The lighting control system 100 automatically corrects the relative positioning coordinates of each positioning and communication base station 30 and records them in the device table of the system database; the user can also define the layout rules of related equipment as needed, such as specifying the spatial plane where the equipment may be installed in the drawing, so as to optimize the subsequent system's calculation accuracy of the coordinates of the access equipment.

[0153] System attribute data, such as a system code, etc., is set on the user interface of the operation terminal device 40 .

[0154] 3. Initialization and Operation of the Automatic Positioning Lamp 10 and the Automatic Positioning Sensor 50:

[0155] Preferably, the automatic positioning lamp 10 starts initialization after being powered on, and reads relevant attribute information of the automatic positioning lamp 10 from the storage unit 121 in the first multi-channel controller module 12, including the second system code and the second device identification number.

[0156] The first positioning and communication module 11 automatically scans the current working environment to determine whether there is a signal from the positioning and communication base station 30, and performs the following operations based on different determination results:

[0157] 1. If the first positioning and communication module 11 detects the signal of the positioning and communication base station 30, it automatically establishes a link and sends data such as the second system code and the second device identification number to the central control server 20. The central control server 20 calculates the distance between the device and different positioning and communication base stations 30 to obtain the three-dimensional coordinate data of the relative position of the device and each base station. The central control server 20 compares the second system code and the second device identification number with the pre-stored first system code and first device identification number to see if they are the same. Based on the different comparison results, the following operations are performed:

[0158] 1.1. If the second system code is the same as the first system code, and the first device identification number of the automatic positioning lamp 10 is recorded in the device table, the central control server 20 queries the working status information in the device table, then the central control server 20 sends a second control instruction to the automatic positioning lamp 10 via the positioning and communication base station 30. After the first positioning and communication module 11 of the automatic positioning lamp 10 receives the second control instruction from the central control server 20, the multi-channel control unit 123 of the first multi-channel controller module 12 converts the second control instruction into a control signal to control the light source 13 to work, thereby realizing the control of the working status of the light source 13 of the automatic positioning lamp 10. During the initialization process, the lighting control system 100 will recalculate the spatial coordinate parameters of the automatically positioned lamp 10 and compare them with the values recorded by the system. If there is any inconsistency, it means that the lamp has been displaced before startup. The lighting control system 100 will send a control instruction to make the indicator light of the automatically positioned lamp 10 prompt according to the corresponding rules, and prompt the user to confirm the displacement in the user interface of the operating terminal. After the user confirms the displacement, the lighting control system 100 will update the device positioning data record and control the automatically positioned lamp 10 to end the indicator light prompt.

[0159] 1.2. If the second system code is the same as the first system code, but the first device identification number of the automatic positioning luminaire 10 is not recorded in the device table, the central control server 20 sends a first new prompt instruction to the automatic positioning luminaire 10 via the positioning and communication base station 30. After the automatic positioning luminaire 10 receives the first new prompt instruction via the first positioning and communication module 11, the multi-channel control unit 123 in the first multi-channel controller module 12 converts the first new prompt instruction into a 100% output control signal to control the operation of the light source 13, thereby controlling the operating state of the light source 13 of the automatic positioning luminaire 10 and controlling the indicator lights therein to operate according to the rules of the first new prompt instruction. Furthermore, the central control server 20 lists the relevant attribute information of the newly added automatic positioning luminaire 10 on the user interface of the operating terminal device 40. After receiving the user confirmation instruction, the information is added to the device table and the device positioning data table in the database. The automatic positioning luminaire 10 is then connected to the lighting control system 100 for management and operates in normal mode.

[0160] 1.3. If the second system code of the automatic positioning luminaire 10 is null, the central control server 20 sends a second new prompt instruction to the automatic positioning luminaire 10 via the positioning and communication base station 30. After the automatic positioning luminaire 10 receives the second new prompt instruction via the first positioning and communication module 11, the multi-channel control unit 123 in the first multi-channel controller module 12 converts the second new prompt instruction into a 100% output control signal to control the operation of the light source 13. Specifically, it drives the adjustable ballast module 131 to operate and controls the indicator lights therein to operate according to the second new prompt instruction. The central control server 20 lists the attribute information of the newly added automatic positioning luminaire 10 on the operation terminal device 40. After receiving the user confirmation instruction, it is added to the device table and device positioning data table of the database. The second new prompt instruction carries the first system code. After receiving the second new prompt instruction, the automatic positioning luminaire 10 records the first system code in the storage unit 121 of the first multi-channel controller module 12. The automatic positioning luminaire 10 is then connected to the system management and operates in normal mode.

[0161] 1.4. If the second system code of the automatically positioned luminaire 10 is not null and is different from the scanned first system code, the automatically positioned luminaire 10 will operate at 100% output and rescan until the scanned first and second system codes are identical, at which point the luminaire will be connected to the lighting control system 100 according to the aforementioned rules. Alternatively, if repeated scans fail and no consistent system code is found, the scanning process will cease and the indicator light will illuminate according to the predetermined rules. Upon receiving a long-press command from the user, the reset switch 122 in the first multi-channel controller module 12 of the automatically positioned luminaire 10 will clear the second system code data in its storage unit 121. The luminaire will then rescan and connect to the lighting control system 100 according to the aforementioned process, and then operate normally.

[0162] 2. If the first positioning and communication module 11 does not find the signal of the positioning and communication base station 30 after multiple scans, the automatic positioning lamp 10 outputs the latest working status recorded in the storage unit 121 of the device, and the indicator light prompts according to the corresponding rules.

[0163] The initialization and working mode of the automatic positioning sensor 50 are similar to those of the automatic positioning lamp 10, but it does not have the action of controlling the adjustable ballast module 31 of the automatic positioning lamp 10 to drive the electric light source. Instead, it inputs the relevant control signals or data collected by the sensor module 53 and operates the system according to the set control logic.

[0164] The software of the operation terminal 40 will generate a graphical user operation interface based on the system database and the architectural space drawings, making system management more intuitive, convenient and easy to operate.

[0165] 4. Device shutdown or restart:

[0166] 1. The central control server 20 is powered off, damaged, or restarted:

[0167] After the central control server 20 is shut down, the positioning and communication base station 30 sends the connection loss status information with the central control server 20 to the automatic positioning lamp 10 and the automatic positioning sensor 50. The automatic positioning lamp 10 continues to operate normally according to the status when the central control server 20 is shut down. The automatic positioning sensor 50 suspends work because it needs to exchange data with the central control server 20. The indicator lights of the automatic positioning lamp 10 and the automatic positioning sensor 50 prompt according to the corresponding settings;

[0168] After the central control server 20 resumes work, it automatically connects to the positioning and communication base station 30 recorded by the lighting control system 100, and scans various devices recorded by the system through it. The automatic positioning lamp 10 works according to the system instructions of the central control server 20, and the automatic positioning sensor 50 exchanges data with the central control server 20 and resumes work. The indicator lights of the automatic positioning lamp 10 and the automatic positioning sensor 50 are restored according to the corresponding settings.

[0169] 2. The positioning and communication base station 30 is powered off or damaged and restarted:

[0170] If some positioning and communication base stations 30 are powered off or damaged and disconnected from the central control server 20, the lighting control system 100 will prompt the user interface of the operating terminal device 40, and data and command signals will be automatically sent and received through other working positioning and communication base stations 30; the positioning data of existing equipment will not be changed. At this time, the positioning parameters of the newly added equipment will be calculated by the lighting control system 100 based on the parameters of the working positioning and communication base stations 30; after the base station equipment in question resumes operation, the lighting control system 100 will automatically resume its positioning and data command transmission and reception;

[0171] After all positioning and communication base stations 30 are powered off or damaged and disconnected from the central control server 20, the lighting control system 100 prompts the user interface of the operating terminal device 40 that the automatic positioning lamps 10 and the automatic positioning sensors 50 cannot interact with the lighting control system 100, and continue to work according to the current status. The indicator lights of the automatic positioning lamps 10 and the automatic positioning sensors 50 prompt according to the corresponding settings; after the base station equipment resumes work, the central control server 20 automatically establishes a connection with it and the automatic positioning lamps 10 and automatic positioning sensors 50 and other equipment, the lighting control system 100 exchanges data, resumes work, and the indicator lights of the automatic positioning lamps 10 and the automatic positioning sensors 50 are restored according to the corresponding settings.

[0172] 3. The automatic positioning lamp 10 and the automatic positioning sensor 50 are powered off or damaged and restarted:

[0173] When the automatic positioning lamp 10 and the automatic positioning sensor 50 are powered off or damaged and disconnected from the central control server 20, the lighting control system 100 will prompt the user interface of the operating terminal device 40, which will not affect the operation of the overall lighting control system 100. The user can delete the corresponding device from the lighting control system 100, or reconfigure or maintain the corresponding device according to actual use; after the automatic positioning lamp 10 and the automatic positioning sensor 50 are restarted, they are connected to the existing lighting control system 100 according to the above initialization procedure to resume normal operation, and the user interface prompt of the operating terminal device 40 is eliminated.

[0174] 5. Management function description:

[0175] 1. Multi-user settings

[0176] The lighting control system 100 of the present invention can be configured with multiple users, with different permissions set for different users. The relevant data is recorded in the user function table of the system database. Basically, each user can be configured with permission areas and manageable devices. A permission area refers to a manageable spatial area set for a user within the system coordinate system. Existing or newly added devices with coordinates located within this spatial area can be controlled or function set by users with management permissions for this spatial area. Manageable devices refer to devices whose control rights are assigned to one or more users. The corresponding users can then control these devices regardless of whether these devices are within their permission areas. The various control modes described below all require corresponding user permissions. A user cannot operate or manage the automatic positioning lamps 10, groups, areas, scenario modes, automatic control schemes, etc. of other users without permission.

[0177] 2. User permission levels

[0178] When the lighting control system 100 of the present invention is initialized, a super user can be set to be generated. The super user has global management authority over the lighting control system 100 and can manage all management areas or devices of the system. The super user can add at least one ordinary user and authorize some management areas or devices for the ordinary user. The ordinary user can add at least one sub-user and authorize some management areas or devices for the sub-user to which he or she has authority. Each upper-level sub-user can add his or her own lower-level sub-user and authorize some management areas or devices for which he or she has authority, forming multiple superior-subordinate control relationships, and the multiple superior-subordinate control relationships are recorded in the user function table of the database of the central control server 20. The superior-subordinate control relationship means that a user can adjust the control operations or status of the sub-user he or she has generated, and the sub-user cannot adjust the control operations or status of the user who generated him or her without authorization.

[0179] 3. Single lamp control

[0180] The operating terminal device 40 of the present invention can send a single lamp control instruction carrying a first device identification number to the central control server 20 via the positioning and communication base station 30. The central control server 20, based on the single lamp control instruction, selects an automatic positioning lamp 10 corresponding to the first device identification number from the device table and controls it. For example, the control function can turn on or off, adjust color temperature, color, illumination direction, displacement, etc. Some control functions require the automatic positioning lamp 10 to have corresponding functional support.

[0181] 4. Control by region

[0182] The operating terminal device 40 of the present invention can send a regional lighting control instruction carrying a regional range to the central control server 20 through the positioning and communication base station 30. The central control server 20 selects at least one automatic positioning lamp 10 whose positioning coordinates are within the regional range from the device table according to the regional lighting control instruction for unified control, such as turning on or off, adjusting color temperature, color, illumination direction, displacement, etc. Some control functions require the automatic positioning lamp 10 to have corresponding functional support.

[0183] The lighting control system 100 selects devices from a device table that match the spatial region selected by the user in the user interface and controls them. When saving the selected region, the selected devices in the region are grouped into a grouping table in the system database for easy access during subsequent control. If the automatic positioning sensors 50 of the automatically positioned luminaires 10 are displaced, they may lose control of them due to moving outside the user's authorized area.

[0184] 5. Control by group

[0185] The operating terminal device 40 of the present invention can send a group lamp control instruction carrying multiple first device identification numbers to the central control server 20 through the positioning and communication base station 30. The central control server 20 selects multiple automatic positioning lamps 10 corresponding to the multiple first device identification numbers carried from the device table according to the group lamp control instruction for control, and generates corresponding logical grouping attributes for them and records them in the grouping table.

[0186] Group control refers to setting up a group of several automatic positioning lamps 10 for unified control, such as turning them on or off, adjusting color temperature, color, illumination direction, and displacement. Some control functions require the automatic positioning lamps 10 to have corresponding functional support. The group refers to the attribute description of the automatic positioning lamps 10. It is a logical group, not a physical group. An automatic positioning lamp 10 can belong to different groups and have multiple different group attributes.

[0187] 6. Scenario Mode

[0188] The user can preset multiple automatic positioning lamps 10, and the working state of the automatic positioning sensor 50 is different scene modes. When the corresponding usage needs arise, directly calling the scene mode can enable many devices to load the corresponding preset parameters, avoiding repeated complex settings.

[0189] 7. Automatic positioning sensor control

[0190] The automatic positioning sensor 50 of the present invention is an important condition input device for the automatic control of the lighting control system 100. The user can set the area controlled by the automatic positioning sensor 50, or specify the corresponding control device / group. When the parameters input by the automatic positioning sensor 50 meet the corresponding conditions, the corresponding automatic control mode can be triggered or the corresponding scenario mode can be called.

[0191] 8. Automatic control

[0192] The lighting control system 100 of the present invention can be set with a variety of automatic control modes: for example, a planned task refers to an automatic control scheme that presets the working status, scenario mode, etc. of the equipment and is repeatedly called once or multiple times when the system clock meets the corresponding conditions; a sequential task refers to a system setting that automatically starts the next automatic control scheme after one automatic control scheme is completed; and the control of the automatic positioning sensor 50 refers to an automatic control scheme that is triggered by the input conditions of the automatic positioning sensor 50 matching the system conditions.

[0193] 9. Control logic and priority:

[0194] 9.1. Subsequent operations overwrite the original control status;

[0195] 9.2. The working status of the device (such as scene mode, automatic control, etc.) can be set to locked or unlocked;

[0196] 9.3. Sub-users can operate the control status of non-locked devices that are authorized by the superior user, but cannot operate non-locked devices that are not authorized by the superior user;

[0197] 9.4. The superior user can override the control status of the device set by the sub-user, regardless of whether the sub-user has locked it;

[0198] 9.5. When multiple users are authorized to control the same device, but there is no hierarchical authority relationship between the users, a user cannot operate a device locked by another user, but can operate a device that is not locked by other users.

[0199] 6. Control Instruction Flow

[0200] The realization of the above-mentioned control function of the lighting control system 100 of the present invention refers to the logical processing of the system control software. The lighting control system 100 outputs the management operation program as a control instruction in a simple and clear manner. Regardless of single-lamp operation, multi-lamp operation, scene mode, sensor control or other automatic control modes, the central control server 20 will eventually calculate the control instruction for the automatic positioning lamp 10. The control instruction includes the first system code of the system, the first device identification number of the automatic positioning lamp 10 to be controlled, the operation command (such as dimming or color adjustment, etc.) and the operation parameter (such as dimming level or color adjustment color code, etc.); the control instruction is widely sent to each automatic positioning lamp 10 through the positioning and communication base station 30. After the first positioning and communication module in the automatic positioning lamp 10 receives the control instruction, the first multi-channel controller module 12 compares the second system code and second device identification number data contained in the instruction with its own storage unit 121 The relative data recorded in the control instruction are compared, and if they are consistent, the first multi-channel control unit 123 executes the operation command in the control instruction. The action of the first multi-channel control unit 123 varies depending on the operation command and operation parameters, or inputs a voltage or current signal to the adjustable ballast module 131 of the automatic positioning lamp 10, or drives other devices on the automatic positioning lamp 10 (such as driving the steering motor to adjust the direction of the lamp, etc.), and the indicator light of the first multi-channel controller module 12 works according to the corresponding rules; after the instruction operation is successful, the first multi-channel controller module 12 records the working status after the operation in the storage unit 121, and sends back the result feedback data in a certain format. After receiving the result feedback data, the central control server 20 records the working status of each device in the system database. If the correct result feedback data is not received, it means that the control instruction is unsuccessful, and a corresponding prompt is issued in the user interface of the operation terminal device 40.

[0201] In summary, the lighting control system of the present invention includes automatic positioning lamps, a central control server, a positioning and communication base station and an operating terminal device. The automatic positioning lamps include a first positioning and communication module, a first multi-channel controller module and a light source. By using indoor precise positioning technology, the automatic positioning lamps can be automatically connected to the lighting control system for management, and the automatic positioning lamps communicate with the positioning and communication base station. The central control server measures the relative position between the lamps and each base station by calculating the distance between the lamps and each base station, and obtains the accurate position of the lamps in the building space by combining the building space drawings or the equipment layout rules defined by the user, and enables the equipment position to be graphically displayed on the operating terminal device, which not only enables the automatic positioning of lamps and other equipment, but also makes system management more intuitive, convenient and easy to operate. In addition, the operating terminal device sends a first control instruction to the central control server, and the central control server generates a second control instruction based on the first control instruction, and sends the second control instruction to the automatic positioning lamp via the positioning and communication base station. After the first positioning and communication module receives the second control instruction from the positioning and communication base station, the first multi-channel controller module converts the second control instruction into a corresponding control signal to control the light source to work. The lighting control system of the present invention boasts a simple structure and is easy to implement. It eliminates the need for additional control signal wiring, significantly reducing the cost of system construction or upgrades. Overall, the present invention offers the advantages of automatic equipment positioning, a simple structure, easy installation and maintenance, convenient operation, economical cost, and flexibility. It is particularly suitable for systematic lighting control and management in venues such as museums, art galleries, and commercial exhibition centers, where lighting equipment frequently needs to be relocated.
