Description

Technical Field

[0001] This application relates to the field of lighting control and monitoring technology, and in particular to offline data synchronization systems, methods, terminals and media applicable to smart lighting systems. Background Technology

[0002] Traditional monitoring systems primarily consist of a control system and a monitoring system. On the control system side, users issue commands to devices through a platform, and the devices send feedback on the execution results to the platform, allowing users to immediately know whether the operation was successful or not. On the monitoring system side, the platform queries the device status in real time and updates the display. Traditional monitoring systems can do this mainly because: 1) They use wired communication: Wired communication is fast and stable, and the platform can immediately receive feedback from the devices after receiving commands; 2) They support a small number of connected devices: Traditional monitoring systems typically connect only a few thousand or tens of thousands of devices, resulting in a relatively small managed area.

[0003] With the development of smart cities, monitoring systems are required to connect millions or even tens of millions of devices and manage much larger areas. Continuing to use wired communication inevitably leads to the following problems: 1) High cost: The larger the area managed by the monitoring system, the larger the area of ​​cabling required, and the higher the overall project cost; 2) Difficult maintenance and management: Maintenance of the equipment requires digging up the cabling, which greatly complicates maintenance and management. Therefore, current projects mainly adopt new communication methods such as wireless (Zigbee, NB, LoRa, etc.) and power line carrier.

[0004] However, the new communication method also brings new problems: 1) Unreliable transmission: During wireless communication, communication between the server and the device may be interrupted due to uncontrollable factors such as weather and geographical environment; 2) Longer feedback time: Due to the longer time delay of the new communication method, the feedback time of the device is several times that of the traditional monitoring system. Summary of the Invention

[0010] In some embodiments of the first aspect of this application, after the controlled luminaire actively initiates a status change, it actively reports the updated status information to the luminaire management platform so that the luminaire management platform can update the luminaire status information stored in the database in real time.

[0011] In some embodiments of the first aspect of this application, the lighting management platform establishes a communication connection with a user terminal and receives user instructions from the user terminal; wherein, when the user terminal turns on monitoring, the lighting management platform queries the status of all controlled lighting fixtures accordingly, and updates the display and the status information of each lighting fixture in the database based on the query results.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the invention.

[0027] like Figure 1 The diagram illustrates the structure of an offline data synchronization system for a smart lighting system according to an embodiment of the present invention. This offline data synchronization system for a smart lighting system includes: a lighting management platform 11, a database 12, and controlled lighting fixtures 13.

[0028] In this embodiment, the lighting management platform 11 interacts and stores data with the database 12, and establishes a communication connection with the controlled lighting fixtures 13. The lighting management platform 11 also establishes a communication connection with user terminals (not shown) (e.g., mobile phones, tablets, wearable devices, etc.). Users send user commands to the lighting management platform 11 through the user terminal. The lighting management platform 11 stores the desired state of each controlled lighting fixture 13 in the database 12 according to the user commands, and sends the user commands to each controlled lighting fixture 13.

[0029] In some feasible implementations, the lighting management platform 11 can be a server; the server can be deployed on one or more physical servers according to various factors such as function and load, or it can be composed of a distributed or centralized server cluster; the database 12 can be a relational database, time-series database, key / value database, document database, graph database, object database, etc.; the controlled lighting fixtures 13 can be streetlights, such as high-mast lights, mid-mast lights, road lights, courtyard lights, lawn lights, or in-ground lights, etc., and this embodiment does not limit them.

[0030] like Figure 2 The diagram illustrates the structure of an offline data synchronization system for a smart lighting system according to an embodiment of the present invention. In this embodiment, the controlled lighting fixtures include at least one online lighting fixture 131 and at least one offline lighting fixture 132.

[0031] Online lighting fixture 131 is connected to the lighting management platform 11 in real time, and after receiving user instructions from the lighting management platform 11, it queries the lighting management platform 11 for the desired status. The lighting management platform 11 reads the desired status of online lighting fixture 131 from the database 12 and sends it to online lighting fixture 131. After receiving the desired status, online lighting fixture 131 compares it with the current status. If the current status is different from the desired status, it decides whether to update its own status based on the timestamp. If the current status is the same as the desired status, it keeps the current status unchanged.

[0032] Offline luminaire 132 is usually offline, and when it connects to the luminaire management platform 11, it will actively query the luminaire management platform 11 for the desired status. The luminaire management platform 11 reads the desired status of offline luminaire 132 from the database 12 and sends it to offline luminaire 132. After receiving the desired status, offline luminaire 132 compares it with the current status. If the current status is different from the desired status, it decides whether to update its own status based on the timestamp. If the current status is the same as the desired status, it keeps the current status unchanged.

[0033] It should be noted that the controlled device in this invention is a lighting fixture. Due to the needs of a scene or effect, the state of the lighting fixture and the timestamps of state changes need to be set. For example, a street light can be set to be on at 6 PM and off at 5 AM; or, for stage effect lighting, it can be set to randomly change its color every few minutes. Therefore, the user command includes not only the desired state information of the controlled lighting fixture but also the timestamp information of the occurrence of that desired state.

[0034] In some examples, when a controlled luminaire actively initiates a status change, it proactively reports the updated status information to the luminaire management platform, allowing the platform to update the luminaire status information stored in its database in real time. For instance, if online luminaire 131 changes to the desired status one hour after a user instruction, it will do so and proactively report the changed status to the luminaire management platform, which will then update the luminaire status in its database. Similarly, if offline luminaire 132 changes to the desired status according to a user instruction, it will immediately report its status to the luminaire management platform after reconnecting to the platform, and the platform will update the luminaire status in its database.

[0035] It's worth noting that in traditional lighting control systems, users issue commands through a software platform. The platform reports a success when all lights within the specified range successfully execute the command, and vice versa. However, if a light or a group of lights in a given area is out of power or damaged for some reason, the user cannot be notified immediately. This leads to repeated command issuance, severely impacting the user experience. The offline data synchronization scheme proposed in this invention effectively solves this problem. Once a user issues a command, there's no need to monitor whether the lights have executed it; the lights automatically update to the desired state once the conditions are met, resulting in a superior user experience.

[0036] Furthermore, traditional lighting control systems rely on the execution status of all lights to provide feedback on command execution results, requiring all lights to maintain a communicative and executable state. However, various environmental and human factors, such as network outages causing disconnection between lights and the server, or lights being unable to execute commands due to power failure or damage, can all affect the success of the entire decision-making process. The offline data synchronization scheme proposed in this invention effectively solves this problem because the system does not need to be aware of the current state of the lights. The platform issues commands, and devices that meet the conditions execute the commands; devices that do not meet the conditions execute the commands when the conditions are met. In this way, the system can effectively eliminate the influence of various adverse factors.

[0037] like Figure 3 The diagram shows a schematic of an offline data synchronization system for smart lighting systems according to an embodiment of the present invention, demonstrating the performance of the offline data synchronization system in monitoring.

[0038] In some examples, when a user opens the monitoring (e.g., opens the monitoring APP), the lighting management platform 11 queries the status of all controlled lighting fixtures 13 and updates the display and the status information of each lighting fixture in the database based on the query results.

[0039] In some examples, when the status of a controlled luminaire changes, it actively reports to the luminaire management platform 11. The luminaire management platform 11 updates the luminaire status stored in the database based on the reported content of each controlled luminaire.

[0040] It is worth noting that traditional lighting status monitoring solutions require real-time communication with the lighting fixtures and continuous querying of their current status to maintain real-time display. However, this constant querying places a heavy load on the server, consuming significant server resources. Furthermore, the real-time communication with the lighting fixtures in traditional solutions requires substantial network resources, which are subject to service fees, greatly increasing user costs. The offline data synchronization solution proposed in this invention significantly reduces these costs, requiring only one network resource usage when the device changes status. Moreover, traditional lighting status monitoring solutions, due to their limited management scope and poor system robustness, are no longer sufficient for smart city construction. The offline data synchronization solution proposed in this invention offers advantages such as a wider management scope, a better user experience, and higher system robustness, effectively meeting the requirements of smart city construction.

[0041] like Figure 4 The diagram illustrates a flowchart of an offline data synchronization method for a smart lighting system according to an embodiment of the present invention. The offline data synchronization method in this embodiment mainly includes steps S41 and S42.

[0042] Step S41: Receive user instructions; the user instructions include the desired state of the lamp and the corresponding timestamp.

[0043] Step S42: According to the user instruction, store the desired state information of the controlled lamps in the database, and send the user instruction to each controlled lamp so that each controlled lamp can determine whether to update the state according to the timestamp based on the comparison result between the desired state and the current state.

[0044] In some examples, the controlled luminaire includes an online luminaire that is connected and communicates with the luminaire management platform in real time; the offline data synchronization method includes: receiving an active query from the online luminaire regarding a desired state; sending the desired state corresponding to the online luminaire to the online luminaire, so that the online luminaire can determine whether to update the state based on a timestamp based on a comparison between the desired state and the current state.

[0045] In some examples, the controlled luminaire includes an offline luminaire that is not connected to the luminaire management platform in real time; the offline data synchronization method further includes: after connecting to the offline luminaire, receiving an active query from the offline luminaire about the desired state; sending the desired state corresponding to the offline luminaire to the offline luminaire so that the offline luminaire can determine whether to update the state according to the timestamp based on the comparison result between the desired state and the current state.

[0046] like Figure 5 The diagram illustrates the structure of an electronic terminal according to an embodiment of the present invention. The electronic terminal in this embodiment includes: a processor 51, a memory 52, and a communicator 53. The memory 52 is connected to the processor 51 and the communicator 53 via a system bus and communicates with them. The memory 52 stores computer programs, the communicator 53 communicates with other devices, and the processor 51 runs the computer programs, enabling the electronic terminal to execute the steps of the offline data synchronization method applicable to smart lighting systems described above.

[0047] The system bus mentioned above can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. This system bus can be divided into address bus, data bus, control bus, etc. For ease of representation, only one thick line is used in the diagram, but this does not indicate that there is only one bus or one type of bus. The communication interface is used to enable communication between the database access device and other devices (e.g., clients, read-write libraries, and read-only libraries). Memory may include Random Access Memory (RAM) and may also include non-volatile memory, such as at least one disk storage device.

[0048] The processors mentioned above can be general-purpose processors, including central processing units (CPUs), network processors (NPs), etc.; they can also be digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components.

[0049] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the offline data synchronization method applicable to a smart lighting system.

[0050] Those skilled in the art will understand that all or part of the steps of the above-described method embodiments can be implemented using computer program-related hardware. The aforementioned computer program can be stored in a computer-readable storage medium. When executed, the program performs the steps of the above-described method embodiments; and the aforementioned storage medium includes various media capable of storing program code, such as ROM, RAM, magnetic disks, or optical disks.

[0051] In summary, this application provides an offline data synchronization system, method, terminal, and medium suitable for smart lighting systems. The offline data synchronization scheme proposed in this invention eliminates the need to monitor whether the controlled lighting fixture has executed user commands; the fixture automatically updates to the desired state once the conditions are met, avoiding repeated command issuance by the user and thus providing a superior user experience. Furthermore, this invention only requires network resources once when the device changes state, significantly conserving network resources. Moreover, this invention offers advantages such as a wider management scope, better user experience, and higher system robustness, effectively meeting the requirements of smart city construction. Therefore, this application effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.
