Description

Technical Field

[0001] This invention relates to a distributed lighting control method and system, belonging to the field of digital data processing technology. Background Technology

[0002] Distributed lighting is a control method based on network communication technology that distributes lighting control across multiple nodes to achieve real-time response to localized lighting needs. The system typically consists of lighting equipment, controllers such as smart dimmers, sensors, a central management platform, and a communication network. Lighting equipment includes LED lamps and conventional lamps, while controllers are responsible for collecting environmental information and providing control commands. Distributed lighting control systems need to manage and control clustered lighting devices across multiple branches. In practical use, individual lighting devices in a branch often malfunction, impacting the overall user experience. Therefore, it is necessary to propose a distributed lighting control method and system to address the challenge of traditional distributed lighting technologies in handling malfunctions of individual lighting devices. Summary of the Invention

[0003] This invention provides a distributed lighting control method and system that can solve the problem of abnormal operation of some lighting terminal devices in a cluster device.

[0008] Based on the normal operating voltage of the lighting equipment, determine whether the selected pin has an operating voltage;

[0009] If the selected pin does not have a working voltage, the information of the selected pin will be added to the folder to be re-examined, and the process of selecting a pin will be repeated until all pins have been selected.

[0016] The lighting concentrator is connected in communication with the server.

[0017] This invention provides a distributed lighting control method and system. By establishing a communication link with a lighting concentrator, it enables the calling and previewing of the main loop control file. The main loop control file includes power-on initial state control, message control, and button control. The message content can receive pin information from the lighting concentrator. By detecting the live wire zero point output control signal using the lighting concentrator's pins, it can determine whether the loop state is at zero point and whether the lighting equipment controlled by the lighting concentrator is in normal working condition. The pin information includes pin label data and voltage data. The received pin information from the lighting concentrator can be stored and managed using a pin management folder.

[0021] 100 - Server; 200 - Lighting Concentrator. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the distributed lighting control method provided by the present invention includes:

[0024] S100, establish a communication link with the lighting concentrator.

[0025] S200 receives pin information from the lighting concentrator to form a pin management folder.

[0026] Specifically, the pin information includes pin label data and voltage data.

[0027] S300: Use the pin management folder to select a pin information.

[0028] S400 determines whether the selected pin has an operating voltage based on the normal operating voltage of the lighting equipment.

[0029] S510: If the selected pin does not have a working voltage, the information of the selected pin is added to the folder to be re-examined, and the process of selecting a pin is repeated until all pins have been selected.

[0030] S520: If the selected pin has an operating voltage, return to the previous step of selecting a pin until all pins have been selected.

[0031] S600 invokes the loop excitation algorithm to perform loop excitation re-inspection on each pin in the folder to be re-inspected.

[0032] S700 obtains pin information for failed retesting.

[0033] S800, return the pin information of the receiving lighting concentrator until a stop monitoring command for the lighting concentrator is received.

[0034] Specifically, the loop control master file is used, which includes power-on initial state control, message control, key control, etc. From the detection of the live wire zero point output control signal to the relay action, there is an action time of about 5-10ms. This action time is related to whether the loop is under load.

[0035] The message control bit is defined as the relay not operating, energizing, or deactivating. After a new power-on, the loop status setting variable is whether it is at zero. The loop control data source and loop status data come from the message content. The loop control data can be parsed to determine the excitation duration of each loop and the excitation interval between loops, with a maximum of two at a time.

[0036] If there is a discrepancy, the control loop state will be adjusted and the system will wait for the zero point to arrive. If the zero point does not arrive, the system will wait for a maximum of 8 milliseconds. Regardless of whether the relay is controlled, the indicator light must be controlled to the correct state. The indicator light state must be synchronized with the actual state. When an excitation is applied between the loops, the pin configuration initialization is required. All excitation voltages must be removed to implement the zero-crossing detection configuration. The power-down detection configuration must be completed in advance, and the initial state of the loop power-on must be set.

[0037] The zero-crossing detection pin configuration and interrupt mode configuration are described in the function description. When using the function description, attention must be paid to the function modification record. In the power-down detection pin configuration and interrupt mode configuration, the power-down interrupt has the highest priority. The function modification record can determine the initial state of the circuit. The function modification record can also report the content of power-on failures, which are set to special values. Erasing one page during function modification takes a maximum of 40 milliseconds; therefore, the flash memory should be erased immediately after reading to prepare for power-down data saving. Otherwise, there will not be enough time.

[0038] When retrieving power-on status parameter settings, the parameters are checked. If the parameters are unreasonable, the default value is used; if they are reasonable, the stored parameter value is used; and if the read fails, the default value is used.

[0039] This application relates to a distributed lighting control method. By establishing a communication link with a lighting concentrator, the method enables the calling and previewing of the main loop control file. The main loop control file includes power-on initial state control, message control, and button control. The message content can receive pin information from the lighting concentrator. By detecting the live wire neutral point using the lighting concentrator's pins, a control signal is output to determine if the loop state is at a neutral point, thus confirming whether the lighting equipment controlled by the lighting concentrator is in normal working condition. The pin information includes pin label data and voltage data. A pin management folder can be used to store and manage the received pin information from the lighting concentrator. When the pins... When the working voltage of each pin in the management folder is checked sequentially, pins without working voltage can be included in the folder to be re-inspected. This removes some invalid lighting equipment, which is beneficial for the inspection and maintenance of malfunctioning lighting equipment. The loop excitation algorithm is called to perform loop excitation re-inspection on each pin in the folder to be re-inspected. The loop excitation can be sent from the lighting equipment end. When no working voltage is found on the pins in the folder to be re-inspected, it can be determined that the circuit is open. When working voltage is found on the pins in the folder to be re-inspected, it can be determined that the working part of the lighting equipment itself is damaged. This realizes the inspection of some abnormal lighting terminal equipment.

[0040] In one embodiment of this application, S100 includes:

[0041] S111, Receives messages from the lighting concentrator.

[0042] S112, parse the message from the lighting concentrator.

[0043] S113, obtain status data of at least one circuit managed by the lighting concentrator.

[0044] S114, Select a loop status data.

[0045] S115, extract the ID code from the selected loop status data.

[0046] S116, return to the selected loop status data, until all loop status data have been selected.

[0047] S117, Generation Circuit Management Folder.

[0048] S118, include ID codes and loop status data in the loop management folder.

[0049] As is understandable, a message is the basic data unit used to transmit information in network communication. The basic structure of a message consists of a header and a body. The header contains control information, such as the source address, destination address, protocol type, and checksum information, while the body carries the actual data content, such as text.

[0050] A lighting concentrator can manage multiple lighting circuits, each with multiple lighting devices within a cluster managed by the concentrator. When some lighting devices malfunction, the concentrator can identify the circuit it manages by analyzing its messages, and then retrieve the circuit's ID code using its status data.

[0051] There is a mapping relationship between ID codes and loop status data. Including both ID codes and loop status data in the loop management folder can facilitate the quick retrieval of loop status data corresponding to the ID code.

[0052] By using the ID codes in the circuit management folder, you can quickly locate the faulty lighting equipment.

[0053] In one embodiment of this application, S100 further includes:

[0054] S121, call the loop management folder.

[0055] S122, Select an ID code.

[0056] S123, search for loop status data to achieve a mapping relationship between the selected ID code and the loop status data.

[0057] S124, return to the previous step of selecting an ID code, until all ID codes have been selected.

[0058] S125, based on ID code, establishes a communication link between the server itself and the lighting concentrator.

[0059] Understandably, there is a mapping relationship between ID codes and loop status data. Using independent ID codes, the server can send commands to the lighting concentrator with relatively high accuracy. Relying on independent ID codes, the lighting concentrator can clearly determine the loop to which the server's command is directed and the pin to which the loop belongs. Based on the ID code, the communication link formed between the server and the lighting concentrator is clearly directional.

[0060] In one embodiment of this application, S200 includes:

[0061] S210, Select an ID code.

[0062] S220, retrieves the loop status data that forms a mapping relationship with the ID code.

[0063] S230 uses a zero-crossing algorithm to determine whether the number of zero-crossing points of the loop corresponding to the ID code is greater than or equal to 2.

[0064] S241, if the number of zero crossings of the loop corresponding to the ID code is greater than or equal to 2, then call the label data of each pin of the loop corresponding to the ID code.

[0065] S242, if the number of zero-crossing points of the circuit corresponding to the ID code is less than 2, then the circuit corresponding to the ID code is determined to be de-energized.

[0066] S250 assigns the selected ID code to the highest-level label for verification.

[0067] S260 parses the circuit corresponding to the ID code and obtains the label data of each pin of the circuit corresponding to the ID code.

[0068] S270, return to the previous step and select an ID code until all ID codes have been selected.

[0069] S280 includes the pin label data in the pin management folder.

[0070] Understandably, loop status data can reflect the operational status of all lighting devices within a lighting loop. ID codes allow the server to send targeted verification commands to each lighting loop. Specifically, the server sends the verification command to the lighting concentrator via the ID code. The lighting concentrator then uses a mapping relationship to generate the verification command result for the corresponding ID code lighting loop. There is a mapping relationship between the ID code and the loop status data.

[0071] Under normal circumstances, the electrical energy between the lighting circuit and the lighting concentrator is alternating current. Under normal operating conditions, the sinusoidal alternating current will have two zero-crossing points in one power cycle. Based on this property, the zero-crossing algorithm can be used to determine whether the number of zero-crossing points of the circuit corresponding to the ID code is greater than or equal to 2.

[0072] If the number of zero crossings of the circuit corresponding to the ID code is greater than or equal to 2, it can be determined that the working status of most lighting devices in this lighting circuit is normal.

[0073] If the number of zero-crossing points of the circuit corresponding to the ID code is less than 2, it is determined that most of the lighting equipment in this lighting circuit is not in normal working condition. In this case, the server will assign the selected ID code a high-level re-examination label to quickly find the cause of the power failure in the circuit corresponding to the ID code and provide feedback to maintenance personnel on the information requiring maintenance.

[0074] Each ID code corresponds to a number of pins. Using a pin management folder, the server can manage each pin of the lighting concentrator. The server uses the pin's number data to detect the operating voltage of each pin to determine the operating status of the lighting device connected to each pin.

[0075] In one embodiment of this application, S400 includes:

[0076] S411 initializes the configuration of the selected pins.

[0077] S412, obtains a historical detection whitelist of the selected pin.

[0078] S413 receives the operating voltage of the selected pin.

[0079] S414 determines whether the historical detection white sheet records the operating voltage of the selected pin.

[0080] S415 If the historical detection whitelist does not record the operating voltage of the selected pin, then it is determined that the selected pin does not have an operating voltage.

[0081] S416, if the operating voltage of the selected pin in the historical white record is used, then determine whether the time interval from the historical white record to the operating voltage is less than or equal to the normal time threshold.

[0082] S417: If the time interval between the historical detection white record and the working voltage is less than or equal to the normal time threshold, then it is determined that the selected pin has a working voltage.

[0083] S418: If the time interval between the historical detection white record and the working voltage is greater than the normal time threshold, then it is determined that the selected pin does not have a working voltage.

[0084] Understandably, the server records the detection data generated by each pin during the detection process. Therefore, before receiving the operating voltage of the selected pin, a historical detection record is generated. This historical detection record is used to record the detection data generated by the pin during the detection process. To ensure the objectivity and accuracy of the recorded detection data, the configuration of the selected pin is initialized. Then, the loop control master file is used. The loop control master file includes power-on initial state control, message control, button control, etc. From the detection of the pin's live wire zero point output control signal to the relay's action, there is approximately a response time of 0 to 10 milliseconds. This response time is related to whether the loop is under load.

[0085] Simply put, if the historical detection whitelist does not record the operating voltage of the selected pin, it can be directly determined that the pin does not have an operating voltage.

[0086] When recording the operating voltage of the selected pin in the historical monitoring whitelist, it's necessary to determine if the relay's operating time is within the normal time threshold, i.e., 5-10ms. If the time interval recorded in the historical monitoring whitelist for the operating voltage is less than or equal to the normal time threshold, then the relay is in normal working condition, the pin has operating voltage, and the entire electrical branch of the lighting equipment and the lighting equipment itself are working normally. If the time interval recorded in the historical monitoring whitelist for the operating voltage is greater than the normal time threshold, then the relay is not in normal working condition. The presence of operating voltage on the pin indicates that the lighting equipment is working normally. Maintenance personnel need to inspect the relay.

[0087] In one embodiment of this application, S400 further includes:

[0088] S421 invokes a historical detection whitelist for a pin that does not have an operating voltage.

[0089] S422 sends a power-on command to engage the relay.

[0090] S423 receives feedback information corresponding to the power-on command.

[0091] S424 determines whether the historical detection white sheet records the pin's operating voltage based on system time.

[0092] S425: If the historical detection white record pin has an operating voltage, then the selected pin is determined to have an operating voltage.

[0093] S426: If the historical detection white sheet does not record the working voltage of the pin, then it is determined that the selected pin does not have a working voltage.

[0094] S427, return to the historical detection whitelist of the pin that does not have a working voltage, until the historical detection whitelists of all pins that do not have a working voltage have been selected.

[0095] Understandably, maintenance personnel need to determine the fault type of lighting equipment with pins that do not have operating voltage during the maintenance process.

[0096] The server sends a power-on command to the lighting concentrator, which then executes a logic command to engage the relay.

[0097] When the historical detection white sheet records the working voltage of the pin, it can be determined that the relay can perform the energizing action, that is, the relay is not faulty.

[0098] When the historical detection white sheet does not record the working voltage of the pin, it can be determined that the relay cannot perform the energizing action, that is, the relay is faulty.

[0099] Testing each pin individually, even those without operating voltage, improves the accuracy of the detection circuit and reduces the impact of relay tripping on the detection circuit.

[0100] In one embodiment of this application, S600 includes:

[0101] S611, Select an ID code.

[0102] S612 retrieves the pin label data for each pin of the circuit corresponding to the ID code.

[0103] S613 selects the label data for a pin.

[0104] S614, in the folder to be retested, find the label data of the selected pin.

[0105] S615, based on the search results, determines whether the label data of the selected pin exists in the folder to be re-inspected.

[0106] S616, if the label data of the selected pin does not exist in the folder to be re-examined, then return to the step of selecting the label data of the selected pin, until the label data of all pins has been selected.

[0107] S617, if the label data of the selected pin exists in the folder to be re-examined, then create the selected ID code folder, add the label data of the selected pin to the ID code folder, and return to the step of selecting the label data of the selected pin, until the label data of all pins has been selected.

[0108] S618, return to the previous step of selecting an ID code, until all ID codes have been selected.

[0109] Understandably, lighting concentrators manage multiple ID codes, each representing a lighting circuit. A lighting circuit has multiple electrical branches. One pin of the lighting concentrator is electrically connected to one of these electrical branches.

[0110] By relying on the zero-crossing algorithm, the working voltage recorded in the historical detection white sheet, and the power-on command of the energizing relay, the pins corresponding to the lighting equipment that are not in operation can be found. The information of these pins is stored in the folder to be re-inspected.

[0111] In order to establish a correspondence between the pins of lighting devices that are not in operation and their ID codes, the pin label data of each pin of the circuit corresponding to the ID code can be searched in the folder to be re-inspected, thus forming the ID code folder.

[0112] Each ID code corresponds to an ID code folder, which may contain pin label data for lighting devices that are not in operation.

[0113] In one embodiment of this application, S600 further includes:

[0114] S621, Select an ID code folder.

[0115] S622, based on the lighting concentrator communication link, issues an excitation release command to the circuit corresponding to the ID code.

[0116] S623, in the selected ID code folder, select a pin label data.

[0117] S624, under system time, searches for the historical detection whitelist of the selected pin's operating voltage record.

[0118] S625, retrieves the search results for historical white slips.

[0119] S626, return to the selected pin label data, until all pin label data has been selected.

[0120] S627, return to the previous step and select an ID code folder until all ID code folders have been selected.

[0121] Understandably, the selected ID code can be based on priority tags. ID codes with higher priority can be re-inspected first. The presence of an ID code with the highest priority tag for re-inspection indicates a circuit fault in the entire lighting circuit. A lighting circuit has multiple lighting electrical branches.

[0122] It is worth mentioning that every lighting device includes a circuit board and a light-emitting component. Damage to the light-emitting component will cause the pins to lose their operating voltage. The circuit board of the lighting device is not affected by damage to the light-emitting component; the circuit board can perform excitation / release actions according to excitation / release commands.

[0123] Simply put, after receiving the excitation release command from the lighting concentrator, the circuit board of the lighting equipment sends an excitation signal to the lighting concentrator in the electrical branch. The voltage of the excitation signal sent by the lighting equipment itself is equal to the operating voltage.

[0124] By checking whether the pins in the ID code folder receive an excitation signal, the specific fault in the electrical branch can be determined.

[0125] In one embodiment of this application, S700 includes:

[0126] S710, select an ID code folder.

[0127] S720, select a historical white slip search result from the ID code folder.

[0128] S730 determines whether the historical test white slip has a working voltage record based on the search results of the historical test white slip.

[0129] S740: If the historical test white sheet does not have a record of the working voltage, it will provide feedback on the circuit break of the lighting equipment.

[0130] S750: If the historical test report has a record of the working voltage, it will provide feedback on the damage to the lighting equipment.

[0131] S760, return the search results of a historical white slip in the selected ID code folder, until all historical white slip search results have been selected.

[0132] S770, return to the previous step and select an ID code folder until all ID code folders have been selected.

[0133] Specifically, based on the system time of the excitation release command transmitted by the lighting concentrator, the search results of the historical detection white sheet can be used to determine whether the lighting equipment circuit is open if the historical detection white sheet does not have a working voltage record, or if the historical detection white sheet has a working voltage record, the lighting equipment is damaged.

[0134] Simply put, when the lighting equipment circuit is normal, the electrical path between the circuit board of the lighting equipment and the pins of the lighting concentrator is complete, and the pins of the lighting concentrator can receive the excitation signal, that is, the historical detection white sheet has the working voltage record.

[0135] When the lighting equipment circuit is broken, the lighting concentrator cannot transmit the excitation release command.

[0136] like Figure 2 As shown, the distributed lighting control system provided by the present invention includes a server 100 and a lighting concentrator 200.

[0137] Server 100 is used to execute distributed lighting control methods.

[0138] The lighting concentrator 200 is communicatively connected to the server 100.

[0139] This embodiment relates to a distributed lighting control system. The server 100 establishes a communication link with the lighting concentrator 200. The server 100 can store and manage the pin information received from the lighting concentrator using a pin management folder. When the working voltage of each pin in the pin management folder is detected sequentially, the server 100 can add the pins without working voltage to the folder to be re-inspected. This realizes the elimination of some invalid lighting devices, which is beneficial for the inspection and maintenance of malfunctioning lighting devices. The circuit excitation algorithm is called, and the lighting concentrator 200 sends an excitation command to the lighting device to perform circuit excitation re-inspection on each pin in the folder to be re-inspected. The circuit excitation can be sent from the lighting device. When the pins in the folder to be re-inspected do not show working voltage, it can be determined that the line is open. When the pins in the folder to be re-inspected show working voltage, it can be determined that the working part of the lighting device itself is damaged. This realizes the inspection of some abnormal lighting terminal devices.

[0140] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
