Description

Automatic positioning lamp and illumination control system

Technical Field

The invention relates to the technical field of lighting equipment, in particular to an automatic positioning lamp and a lighting control system.

Background

With the development of modern society, people increasingly recognize the importance of lighting in life, and especially in places with high lighting requirements, such as museums, art museums, trade exhibition centers, airports, high-speed railway stations and the like, the requirement for accurate control (switching and dimming) of lighting is higher and higher. The prior art has the following technical schemes:

first, through loop control

I.e. several lamps are connected in parallel or in series in a loop, and a switch and a dimmer are added in the loop to control the illumination. The scheme is common, the engineering installation is simple, and the simultaneous control of the on-off or dimming of a plurality of lamps can be realized; however, if each lamp is controlled individually in a large lighting project, the installation and wiring process is very large, the cost is very high, and in use, since the lamps and the control switches and the dimmers are separated, a user is required to be able to clearly know the one-to-one correspondence relationship between each lamp and each control switch and dimmer, which is obviously unrealistic, so that the control is performed by installing an independent loop for each lamp, which is generally not applicable to many application projects of lamps.

Secondly, the control is realized through a switch on the lamp and a dimming unit

Namely, each lamp is provided with an independent switch and a dimmer for control. The scheme can realize independent switching and dimming of each lamp, and other lamps are not influenced; compared with loop control, the scheme has no problems of large engineering quantity and high installation cost in single lamp control, does not require a user to clearly know the corresponding relation between the lamp and the switch, and is a common use scheme of an application project aiming at the single lamp dimming requirement at present. However, a serious disadvantage of this solution is that when the lighting fixture is installed, the user needs to adjust the lighting environment, and must climb to the high place where the lighting fixture is installed to operate each lighting fixture, which is very inconvenient, especially for places with many lighting fixtures and more changed lighting environments, such as museums, art museums, trade show centers, etc. that are frequently replaced, the workload and operation cost of the user are greatly increased, and the locations where the lighting fixture is installed at a high height or is difficult to reach, even the danger of operation is increased.

Dimming of three-digit addressable light interface system

The Digital Addressable light Interface system comprises DALI (Digital Addressable Lighting Interface protocol), DMX and the like, wherein DALI is taken as an example, DALI is a data transmission protocol and defines a communication mode between an electronic ballast and an equipment controller, the basic system structure of the system is that the DALI ballast integrating a combination switch and dimming control is connected to a 2-core control line through a DALI Interface, the system addresses each ballast respectively, and the system identifies and controls each lamp according to the addressing. However, the latest lighting intelligent control system has several significant problems:

1. two separate 2 control wires (or 2 core wires) are needed, the main power wire and the control wires are required to be isolated, the current on the control wires is 250mA, and the voltage drop does not exceed 2V when the wires are 300 m long; this brings great inconvenience to the system installation, especially if the system is used in the constructed project, the newly-added laying control line is needed, and the difficulty is very great.

2. The debugging of the DALI system is very tedious and needs to be performed by a professional, especially if a certain lamp is damaged, the parameter setting of the lamp needs to be performed by special equipment even if a new lamp is replaced, otherwise, the system management cannot be performed, and the debugging is difficult to be performed independently by a general user.

3. The addressing of the DALI ballast is completed during system debugging, and the address of any ballast on a control line is uncertain after each debugging, so when a certain ballast in the system is in failure and needs to be replaced, the ballast on the new replacement needs to be the same as the address of the replaced ballast instead of simply replacing the ballast with a new one, the address of the ballast needs to be addressed again by means of special debugging equipment at present, and otherwise, address conflict can occur; very strict management methods are required to ensure the operation and maintenance of the system, otherwise system disorder is likely to occur.

4. When the system is reset, if the system is crashed, equipment is updated, or even only one lamp is newly added to the system, all lamps need to be addressed and addressed again; because the DALI address of each luminaire is randomly generated, all the original settings (e.g., group, scene mode, timing settings, etc.) and data will be completely confused and need to be completely reset, i.e., the whole project needs to be debugged again.

5. The user is controlling lamps and lanterns through central control system usually, requires that the user has higher professional knowledge, owing to can not the direct observation the on-the-spot effect of illumination, needs many people cooperation and or auxiliary assembly just can carry out the accurate configuration of illumination moreover, has additionally increased manual work and equipment cost.

Four, wireless lighting control system

Lighting control systems based on bluetooth mesh, ZigBee (ZigBee) and other radio frequency communication schemes are also being used more and more. The wireless lighting control system is not required to be paved with signal lines, is convenient and flexible to use, but due to the wireless communication, the system can not confirm the specific position of the lamp equipment controlled by the system actually, and brings inconvenience to management and maintenance; if the system is used in a small range, complex and strict management measures are required to be additionally used for controlling the overall illumination of a large building, and huge management cost is increased.

In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.

Preferably, the positioning and communication module and the central control server 20 are in data communication via a Wireless (WIFI) or wired (ethernet) communication network.

Preferably, the operation terminal device 40 and the central control server 20 perform data communication through a Wireless (WIFI) or wired (ethernet) via a general network.

Preferably, the lighting control system 100 may further include at least one automatic positioning sensor 50, as shown in fig. 3, wherein the automatic positioning sensor 50 communicates with the central control server 20 through the positioning and communication base station 30.

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, i.e. the structure and the working principle are the same.

The second positioning and communication module 51 is configured to communicate with each positioning and communication base station 30 when the automatic positioning sensor 50 is connected to the lighting control system 100, and the central control server 20 measures the relative position between the automatic positioning sensor 50 and each positioning and communication base station 30 by calculating the distance between the automatic positioning sensor 50 and each positioning and communication base station 30, and then calculates the accurate position of the automatic positioning sensor 50 in the building space by combining with the building space drawing or the user-defined device layout rule.

It should be noted that the above is merely an example of the application of the automatic positioning sensor 50, and the practical application of the automatic positioning sensor 50 may be more flexible and richer obviously.

The automatic positioning sensor 50 is actually an input device, and the automatic positioning sensor 50 of the present invention mainly includes actions of accessing the lighting management and control system 100 (the same process as the automatic positioning lamp 10) and collecting system working environment data. For example, whether a person is present or not, the illumination of the space, etc. are sensed, then, the system working environment data is transmitted to the central control server 20, and the central control server 20 generates a related control instruction according to the received system working environment data, in combination with conditions (such as some set thresholds) and response strategies preset by the user, and controls some automatic positioning lamps 10 to work.

The automatic positioning sensor 50 belongs to a working-end device, which is not a necessary device of the lighting control system 100, and in practical applications, the automatic positioning sensor 50 may be configured or not configured according to the use requirement.

The invention can automatically position the lamp 10 based on the accurate positioning technology, and the control module can automatically construct the lighting control system of the space arrangement diagram of the lighting equipment according to the lamp positioning data. Specifically, the invention provides an automatic positioning lamp 10 and an illumination control system 100, without laying a control signal line additionally, the automatic positioning lamp 10 communicates with a positioning and communication base station 30, a central control server 20 measures the relative position between the automatic positioning lamp 10 and each positioning and communication base station 30 by calculating the distance between the automatic positioning lamp 10 and each positioning and communication base station 30, and obtains the accurate position of the automatic positioning lamp 10 in a building space by combining a building space drawing; the central control server 20 transmits the control instruction of the operation terminal device 40 to the automatic positioning lamp 10 through the positioning and communication base station 30, so that the automatic positioning lamp 10 can be controlled by dimming light of a single lamp or a group, and the automatic positioning lamp 10 has the advantages of simple structure, convenience in installation, easiness in debugging, intuition, convenience, easiness in operation, stable performance and the like. The whole lighting system is convenient to maintain, economical in manufacturing cost, flexible, convenient, suitable for engineering application of various scales, and particularly suitable for lighting systematic control and management of places where lighting equipment frequently needs to move positions, such as museums, art museums, commercial exhibition centers and the like.

Preferably, the database of the central control server 20 is pre-stored with at least an equipment table, a group table, a system attribute table, a building table, and the like.

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

The system attribute table records system attribute data, wherein the system attribute data at least comprises a first system code number of the system, and the first system code number is unique.

The building form records a building space drawing, positioning index information of each positioning and communication base station 30 in the building space drawing, and a user-defined device layout rule.

The central control server 20 is configured to generate a second control instruction according to the first control instruction, where the second control instruction includes the first system code, the first device identification number of the automatic positioning luminaire 10 to be controlled, the operation command, and the operation parameter, and send the second control instruction to the automatic positioning luminaire 10 through 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 13.

The first positioning and communication module 11 is configured to receive a second control command forwarded by the positioning and communication base station 30.

As shown in fig. 4, 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:

the storage unit 121 is configured to store a second device identification number of the luminaire, a latest operating state, and/or a second system code of the connected lighting control system 100. Specifically, the second device identification number is unique and is fixed in the storage unit 121, and is usually written in the factory, and is not modifiable and not erased due to device reset. And the second system code is received from the management system when the equipment is added into the management system.

The reset switch 122 is configured to clear various setting data in the storage unit 121, and is configured to clear the original setting data before the device accesses the new lighting control system 100.

The multi-channel control unit 123 is configured to control the automatic positioning lamp 10, and is configured to provide an input end for feeding back the operating state of the device. For example, for the on/off, brightness adjustment, color temperature adjustment, color adjustment, and illumination direction adjustment of the automatic positioning lamp 10, the functions of the multi-channel control unit 123 of the multi-channel controller module of different intelligent working end devices are slightly different according to the control requirements of the devices;

the indicator light 124 is used for prompting the working state of the device, the state of the access system and/or the positioning state and the like. For example, when the device scans the signal environment of the peripheral system, the indicator light slowly flashes blue; when the device has accessed the lighting control system 100 but automatically resets the positioning or initialization system data, the indicator light flashes blue rapidly; when the equipment is connected to the lighting control system 100 and works normally according to the system instruction, the indicator light is turned off; equipment failures such as automatic positioning of light fixture 10 light source damage, etc., red flashing of indicator lights, etc.

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 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 121. If the two control commands are consistent, the multi-channel control unit 123 converts the second control command into a corresponding control signal, and controls the light source body 13 to operate according to the operation command and the operation parameter.

After the second control instruction is successfully operated, the first multi-channel controller module 12 records the operated working state in the storage unit 121, and returns the result feedback data to the central control server 20.

It should be noted that the second multi-channel controller module 52 of the automatic positioning sensor 50 has the same structure and working principle as the first positioning and communication module 11 of the automatic positioning lamp 10, and therefore, the description thereof is omitted for the sake of avoiding redundancy.

The invention utilizes the indoor accurate positioning technology, enables the lighting equipment to be automatically accessed to the lighting control system 100 for management by the system code, the equipment identification number and the database informatization technology, and combines the imported building space drawing to enable the equipment position to be embodied in a graphical interface, so that the system management is more intuitive, convenient and fast, the operation is easy, the operation personnel is more friendly, and the operation cost is saved without special technical training; setting multi-level user authority, and managing an authorization scheme according to regions; the control instruction is in a combination form of system code, equipment identification number, operation command and operation parameter, so that the scheme can be rapidly increased and various existing common lamps using wired signals to control the switch and adjust the light can be rapidly increased.

For a better understanding of the present invention, the operation and flow of the lighting control system 100 in the preferred embodiment are described as follows:

Preferably, the system attribute data includes a building name, a geographical location, a system code number, a system time, and the like.

Second, explanation of system initial settings:

as shown in fig. 5 and 6, the hardware devices of the positioning and communication base station 30 are 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 accessed to the same general network;

the central control server 20 is automatically connected to the user interface of the operation terminal device 40, and user data such as a setting manager and users with different authority levels are initialized.

A building space drawing is imported into a user interface of the operation terminal device 40, a position index of the installed positioning and communication base station 30 is set in the building space drawing, and the lighting control system 100 automatically corrects the relative positioning coordinates of each positioning and communication base station 30 and records the relative positioning coordinates into a device table of a system database; the user may also define layout rules of the relevant devices as needed, for example, specify a spatial plane where the devices may be installed in the drawing, so as to optimize the calculation accuracy of the subsequent system on the coordinates of the access device.

System attribute data such as a system code number and the like is set in a user interface of the operation terminal device 40.

Initialization and working description of the automatic positioning lamp 10 and the automatic positioning sensor 50:

preferably, the automatic positioning lamp 10 starts initialization after being powered on, and the automatic positioning lamp 10 reads the 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, the second device identification number, and the like.

The first positioning and communication module 11 automatically scans the current working environment, determines whether there is a signal of the positioning and communication base station 30, and executes the following operations according to different determination results:

1. if the first positioning and communication module 11 finds the signal of the positioning and communication base station 30, a link is automatically established, and data such as a second system code and a second equipment identification number are sent to the central control server 20, and the central control server 20 obtains the three-dimensional coordinate data of the relative position of the equipment and each base station by calculating the distance between the equipment and different positioning and communication base stations 30; the central control server 20 compares whether the second system code and the second equipment identification number are the same as the pre-stored first system code and the pre-stored first equipment identification number, and according to different comparison results, executes the following operations:

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 has a record in the device table, the central control server 20 queries the working state information in the device table, 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 of the central control server 20, the second control instruction is converted into a control signal through the multi-channel control unit 123 of the first multi-channel controller module 12 to control the light source body 13 to work, and further, the working state control of the light source body 13 of the automatic positioning lamp 10 is realized. During the initialization process, the lighting control system 100 recalculates the spatial coordinate parameters of the automatic positioning lamp 10 once, compares the values recorded by the system, and if the values do not match, it indicates that the lamp has moved before starting, the lighting control system 100 sends a control command to prompt the indicator light of the automatic positioning lamp 10 according to the corresponding rule, and prompts the user to confirm the movement on the user interface of the operation terminal, and after the user operates to confirm the movement, the lighting control system 100 updates the device positioning data record, and controls the automatic positioning lamp 10 to end the indicator light prompt.

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 lamp 10 is recorded in the device table, the central control server 20 sends a first new increase prompting instruction to the automatic positioning lamp 10 through the positioning and communication base station 30, and after the automatic positioning lamp 10 receives the first new increase prompting instruction through 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 increase prompting instruction into a 100% output control signal to control the light source body 13 to work, thereby realizing the working state control of the light source body 13 of the automatic positioning lamp 10, and controlling the indicator lamp therein to work according to the rule of the first new increase prompting instruction. In addition, the central control server 20 lists the related attribute information of the newly added automatic positioning lamp 10 in the user interface of the operation terminal device 40, and after receiving the user confirmation instruction, adds the device table and the device positioning data table in the database, and the automatic positioning lamp 10 is connected to the lighting control system 100 for management, and operates in a normal mode.

1.3, if the second system code of the automatic positioning lamp 10 is null, the central control server 20 sends a second new prompt instruction to the automatic positioning lamp 10 through the positioning and communication base station 30, after the automatic positioning lamp 10 receives the second new prompt instruction through 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 light source body 13 to work, specifically, drive the adjustable ballast module 131 to work, and control the indicator lamp therein to work according to the second new prompt instruction rule. The central control server 20 lists the attribute information of the newly added automatic positioning lamp 10 in the operation terminal device 40, and after receiving a user confirmation instruction, adds the attribute information into the device table and the device positioning data table in the database, where a second newly added prompt instruction carries a first system code, and after receiving the second newly added prompt instruction, the automatic positioning lamp 10 records the first system code into the storage unit 121 of the first multi-channel controller module 12, and the automatic positioning lamp 10 accesses the system management to operate in a normal mode.

1.4, if the second system code of the automatic positioning lamp 10 is not null and is different from the scanned first system code, 10100% of the automatic positioning lamp is output and rescanned, and the automatic positioning lamp is accessed to the illumination control system 100 for management according to the rule until the scanned first and second system codes are the same; or the scanning is stopped after repeated scanning for a plurality of times and no consistent system code number exists, and the indicating lamp prompts according to a preset rule. After receiving the long-press instruction from the user, the reset switch 122 in the first multi-channel controller module 12 of the automatic positioning luminaire 10 clears the second system code data of the storage unit 121 of the device, and then operates in the normal mode after rescanning and accessing the lighting control system 100 for management as in the above procedure.

2. If the first positioning and communication module 11 scans for multiple times and does not find the signal of the positioning and communication base station 30, the automatic positioning lamp 10 outputs the latest working state recorded by the storage unit 121 of the device, and the indicator light prompts according to the corresponding rule.

The initialization and operation mode of the automatic positioning sensor 50 is similar to that of the automatic positioning lamp 10, but the automatic positioning lamp 10 does not control the adjustable ballast module 31 to drive the electric light source, but inputs the relevant control signal or data collected by the sensor module 53, and performs the system operation according to the set control logic.

The software of the operation terminal device 40 can generate a graphical user operation interface according to the system database and the building space drawing, so that the system management is more visual, convenient and easy to operate.

Fourthly, shutting down or restarting the equipment:

after the central control server 20 resumes operation, the positioning and communication base station 30 recorded by the lighting control system 100 is automatically connected, and through various devices recorded by the scanning system thereof, the automatic positioning lamp 10 operates according to the system instruction of the central control server 20, the automatic positioning sensor 50 performs data exchange with the central control server 20, resumes operation again, and the automatic positioning lamp 10 and the indicator light of the automatic positioning sensor 50 resume operation according to the corresponding settings.

2. Power-off or damage and restart of the positioning and communication base station 30:

when a part of the positioning and communication base stations 30 is powered off or damaged and disconnected from the central control server 20, the lighting control system 100 prompts a user interface of the operation terminal device 40 that data and instruction signals are automatically received and transmitted by the positioning and communication base stations 30 in other works; the positioning data of the existing device is not changed, and the positioning parameters of the newly added device are calculated by the lighting control system 100 according to the working positioning and communication base station 30 parameters; after the part of base station equipment resumes working, the lighting control system 100 automatically resumes its positioning and data instruction transceiving;

all the positioning and communication base stations 30 are powered off or damaged, and after the base stations are disconnected from the central control server 20, the lighting control system 100 prompts a user interface of the operation terminal device 40 that the automatic positioning lamp 10 and the automatic positioning sensor 50 cannot interact with the lighting control system 100 and continue to work according to the current state, and indicator lights of the automatic positioning lamp 10 and the automatic positioning sensor 50 prompt according to corresponding settings; after the base station equipment resumes working, the central control server 20 automatically establishes connection with the equipment, such as the automatic positioning lamp 10 and the automatic positioning sensor 50, and the lighting control system 100 exchanges data and resumes working again, and the indicator lights of the automatic positioning lamp 10 and the automatic positioning sensor 50 resume working according to corresponding settings.

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

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 prompts a user interface of the operation terminal device 40, so that the work of the whole lighting control system 100 is not affected, and a user can delete corresponding devices from the lighting control system 100 or reconfigure or maintain the corresponding devices according to actual use; after the automatic positioning lamp 10 and the automatic positioning sensor 50 are restarted, the lamp is connected to the existing lighting control system 100 according to the initialization program to recover to normal operation, and the user interface prompt of the operation terminal device 40 is eliminated.

Fifthly, management function explanation:

1. multi-user settings

The lighting control system 100 of the present invention can set up multiple users, set up different authorities to different users, the relevant data is recorded in the user's function table of the system database; basically, the authority area and the manageable device of each user can be set; the authority area is a manageable space area set for a user in a system coordinate system, and the existing or newly added coordinates of equipment in the space area can be controlled or set with functions by the user with the authority of the space area management; a manageable device refers to a device that is assigned control rights for certain devices to one or more users, and the corresponding users can control the devices regardless of whether the devices are in their zone of authority. The following various control modes all require corresponding user rights; one user may not operate or manage the automatic positioning of luminaires 10, groups, areas, profiles, automatic control schemes, etc. of other users without authority.

2. User permission level

When the lighting control system 100 of the present invention is initialized, a super user may be set and generated, and the super user has a global management authority for the lighting control system 100, and may 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 area or device for the ordinary user. The general user can add at least one sub-user, and authorize a part of the management area or equipment with the authority for the sub-user, each upper-level sub-user can add a next-level sub-user, and form a multiple upper-level and lower-level control relationship for the management area or equipment with the authority for the authorized part, and record the multiple upper-level and lower-level control relationship in the user function table of the database of the central control server 20. The upper and lower level control relationship means that the user can adjust the control operation or state of the sub-user generated by the user, and the sub-user cannot adjust the control operation or state of the user generated by the sub-user when the sub-user is not authorized.

3. Single lamp control

The operation terminal device 40 of the invention can send a single lamp control instruction carrying a first device identification number to the central control server 20 through the positioning and communication base station 30, and the central control server 20 screens out an automatic positioning lamp 10 corresponding to the carried first device identification number from the device table according to the single lamp control instruction for control. Such as turning on or off, adjusting color temperature, color, illumination direction, displacement, etc., some of the control functions require the automatic positioning fixture 10 to have corresponding functional support.

The lighting control system 100 will select the device with the positioning coordinate meeting the condition from the device table according to the spatial region selected by the user in the operation interface for control. When the device is used for selecting and storing the areas, the generated area grouping attributes are recorded in a grouping table of a system database by the device obtained by screening in the areas, so that the device is convenient to call in the subsequent control process. When the automatic positioning light fixture 10 is displaced from the respective dynamic positioning sensor 50, the control authority of the user may be lost due to the displacement from the authority area of the user.

5. Group-wise control

The group-based control means that a plurality of automatic positioning lamps 10 are controlled in a group-based manner, for example, turning on or off, adjusting color temperature, color, irradiation direction, displacement, and the like, and part of the control functions require corresponding functional support of the automatic positioning lamps 10. The group is an attribute description of the automatic positioning luminaire 10, and is a logical group, not a physical group, and one automatic positioning luminaire 10 may belong to a group that cannot, that is, may have a plurality of different group attributes.
