Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting device control, and in particular to a lighting device detection method and device and a lighting system. BACKGROUND

[0002] DALI (Digital Addressable Lighting Interface) is a two-way digital communication protocol designed for intelligent lighting, and its core function is to realize precise dimming, grouping control and state feedback of a single lamp through standardized signals such as 0-10V voltage values or digital pulses. DALI can precisely control devices on the DALI bus through short addresses, and can also realize overall control of multiple DALI devices through grouping. The DALI protocol opens up the method for the host to allocate addresses to slave devices. The mainstream DALI short address allocation method is binary method, which compares a total of 24-bit random addresses generated by DALI devices, and each addressing needs at most 24 comparisons, which is the fastest random address addressing method in related technologies.

[0003] However, since the DALI protocol is applied to large lighting systems and uses double-byte communication, a host device using the DALI protocol for communication can support at most 64 slave lamp devices, and the slave devices can be lighting lamps and the like. In actual use, the DALI bus is prone to the phenomenon that the slave devices such as DALI lighting lamps are not controlled due to the access of more than 64 slave devices. SUMMARY

[0004] Therefore, the present application provides a lighting device detection method, device and lighting system to solve or at least partially solve the above technical problems.

[0006] The application discloses a lighting device detection method. In the process of addressing a plurality of slave devices by a host device, after the host device sends an addressing request to the plurality of slave devices, when feedback information of the slave devices responding to the addressing request is detected, the number of the slave devices connected to the host device is counted, so that when the addressing request indicates that the host device completes the addressing operation, whether the number of the slave devices exceeds the limit is quickly judged based on the relationship between the counted number of devices and a first threshold.

DETAILED DESCRIPTION

[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0026] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. Figure 1 The structure of the lighting system in the embodiments of the present application is shown in a schematic diagram, and reference is made to Figure 1 The lighting device includes a host device 101 and a plurality of slave devices 102. The host device 101 and the slave devices 102 communicate through a digital addressable lighting interface (not shown in the figure) and a DALI bus 103 conforming to the DALI interface protocol.

[0027] Further, in order to illustrate the difference between the embodiments of the present application and the related art, the detection method of the DALI protocol lighting system in the related art is described. Figure 2 The flowchart of the detection method of the DALI protocol lighting system in the related art is shown in FIG. 2. Reference is made to Figure 2 The detection method of the DALI protocol lighting system in the related art can include the following steps. Step S201: Control the host device and the plurality of slave devices to enter a device quantity checking mode and start device quantity detection.

[0028] Step S202: Start a silent mode.

[0029] Specifically, after the silent mode is started, the host device no longer performs other operation steps except the necessary operation steps of device quantity detection, and the host device no longer sends commands to the slave devices that do not conform to the DALI protocol.

[0030] Step S203: Suspend the activity of the DALI device.

[0031] Here, the DALI device is a slave device that communicates with the host device through a DALI protocol-compliant interface. Here and in other descriptions of the present solution, the slave device can be connected to one or a group of lighting fixtures, and the slave device can control the lighting fixtures based on the instructions received from the host device.

[0032] Step S204: Clear the short address.

[0033] Specifically, the DALI device stored short address before the current time is cleared, and it is ensured that the short address allocated by the host device to the slave device after the operation step is completely new and conflict-free.

[0034] Step S205, initializing the DALI device.

[0035] Specifically, the DALI device can be controlled to perform an initialization operation, so that the DALI device is in an initial state in which address allocation and the like can be performed.

[0036] Step S206, initializing a random address.

[0037] Specifically, a random address can be initialized for the DALI device, which is the basis for subsequent binary comparison of the random address, and each device will generate a unique random address.

[0038] Step S207, binary comparison of the random address.

[0039] Specifically, the host device can divide the 24-bit random address into 3 random address bytes using the binary method, and from the highest random address byte, by constantly adjusting the comparison value, the unique random address of each slave device is determined.

[0040] Step S208, determining whether the binary comparison of the random address is completed. If yes, all steps are ended, and the addressing operation of the DALI device is completed. If no, return to step S207.

[0041] Step S209, writing a short address.

[0042] Specifically, in the process of addressing by the host device using the binary method to compare the random address, a short address can be written for the DALI device addressed by the host device, and the DALI device addressed by the host device in each round of addressing process is usually the DALI device with the smallest random number. The individual short address addressing range in the DALI protocol is generally 0-63.

[0043] Step S210, exiting the operation.

[0044] After the short address writing is completed, the corresponding DALI device is controlled to exit the addressing and short address writing operation state.

[0045] Step S211, address checking.

[0046] Specifically, after the host device completes the short address writing for the plurality of DALI devices, the written short address needs to be checked to ensure the correctness and uniqueness of the short address, and to avoid conflicts and the like of the short addresses of multiple DALI devices. After the address checking is completed, return to step S207.

[0047] Since only 64 short addresses are configured in the addressing and short address writing process of the DALI device, the host device in the prior art will exit the addressing operation after completing the addressing of 64 DALI addresses and the address checking. If the number of devices exceeds 64, address conflicts and other problems may occur. At this time, the lighting system fails, but cannot remind the user of the specific fault type, and cannot timely and accurately query the number of devices exceeding the limit. Based on this, the present application provides a lighting device detection method to solve the above technical problems.

[0048] According to the embodiment of the present application, a lighting device detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0049] In this embodiment, a lighting device detection method is provided, which can be used in the host device of the lighting system described above. The lighting device includes a host device and a plurality of slave devices, and the host device and the slave devices communicate with each other through a digital addressable lighting interface, Figure 3 is a flowchart of the lighting device detection method according to the embodiment of the present application, as shown in Figure 3 The flowchart includes the following steps: Step S301, sending an addressing request to a plurality of slave devices.

[0050] In some optional embodiments, the addressing request can be an instruction carrying a random address range conforming to the digital addressable lighting interface protocol, so that when the slave device receives the addressing request, it compares its own random address with the address range carried by the addressing request. If the slave device's own random address is in this address range, the slave device returns YES or other information to the host device to indicate that there is a slave device with a random address in this range.

[0051] It can also carry a unique random address conforming to the digital addressable lighting interface protocol, that is, the host device compares a plurality of random addresses conforming to the digital addressable lighting interface one by one with the random address of the slave device itself to determine the random address of the slave device. However, this embodiment consumes a large amount of data storage space and needs to process a large amount of data, which is extremely inefficient. Therefore, the embodiment of the present application also provides a way of broadcasting random addresses using the bisection method to send an addressing request to a plurality of slave devices.

[0052] Step S302, when detecting the feedback information of the slave device responding to the addressing request, counting the number of the slave devices connected with the host device, wherein the feedback information is used to represent that the device address of the slave device sending the feedback information matches the random address carried by the addressing request.

[0053] In some optional embodiments, the essence of the binary addressing is a process of gradually narrowing the range of the random address to determine the unique random address of each slave device. The feedback information can be the response information of the slave device responding to the unique random address sent by the host device, and the feedback information is used to indicate that the unique random address sent by the host device matches the random address of the slave device itself.

[0054] The number of the slave devices can be counted, and after determining the random address of each slave device itself, the number of the slave devices is added by one, so that the number of the slave devices is directly obtained when the addressing request indicates that the host device completes the addressing operation.

[0055] Step S303, when the addressing request indicates that the host device completes the addressing operation, determining whether the number of the slave devices is over limit based on the relationship between the number of the devices and the first threshold.

[0056] Specifically, the first threshold can be 64. If the number of the devices is greater than 64, it can be determined that the number of the slave devices is over limit, and the over limit number is the difference between the number of the devices and the first threshold.

[0057] If the number of the devices is less than or equal to the first threshold, it is determined that the number of the slave devices meets the requirement of the digital addressable lighting interface protocol.

[0058] The lighting device detection method, when the host device sends the addressing request to the plurality of slave devices, the host device counts the number of the slave devices connected with the host device when detecting the feedback information of the slave device responding to the addressing request, so that when the addressing request indicates that the host device completes the addressing operation, the number of the slave devices is quickly determined based on the relationship between the counted number of the devices and the first threshold. If the number of the slave devices is over limit, the over limit number of the slave devices can be quickly and accurately calculated according to the number of the slave devices and the first threshold. Based on this, when the number of the devices is over limit, the over limit slave devices can be quickly processed based on the over limit number of the slave devices, so as to quickly solve the device over limit problem of the lighting system, and avoid detecting the number of the slave devices multiple times in the process of solving the device over limit problem.

[0059] In the embodiment, a lighting device detection method is provided, which can be used for the host device of the above-mentioned lighting system. The lighting device includes a host device and a plurality of slave devices, the host device and the slave devices communicate with each other through a digital addressable lighting interface.Figure 4 is a flowchart of a lighting device detection method according to another embodiment of the present application, as shown in Figure 4 The flowchart includes the following steps: Step S401, control the host device and the plurality of slave devices to enter a device number checking mode.

[0060] In some optional embodiments, step S401 can include: Step S4011, control the plurality of slave devices to suspend performing control operations.

[0061] Specifically, in the DALI protocol, when the host device and the plurality of devices enter the device number checking mode, the host device controls the slave devices to suspend performing control operations, the slave devices will suspend activities related to normal data communication and control, and stop sending instructions. Control other devices in the lighting system in addition to the host device and the slave devices to enter a silent state, for example, control sensors and the like in the lighting system to no longer send data to the host device. When the host device initiates the slave device number checking mode, a specific instruction will be sent to the slave devices, and after the slave devices receive the instruction, they enter a waiting state, stop performing normal control operations such as dimming, switching lights, and the like, and no longer actively send data frames such as state reports, fault information, and the like to the host device. The slave devices will remain silent until the host device completes the slave number detection and sends a new instruction to the slave devices, the new instruction is used to instruct the slave devices to perform control tasks. The slave devices resume normal control operations after receiving the new instruction.

[0062] Step S4012, clear the short addresses of the plurality of slave devices for communication with the host device.

[0063] Specifically, the short addresses stored by the plurality of slave devices before the current time are cleared, to ensure that the short addresses allocated by the host device to the slave devices after this operation step are completely new and conflict-free.

[0064] Step S4013, control the plurality of slave devices to perform initialization operations.

[0065] For details, please refer to step S205 of the embodiment shown in Figure 2 herein.

[0066] Step S4014, initialize random addresses conforming to the communication protocol of the digital addressable lighting interface.

[0067] For details, please refer to step S206 of the embodiment shown in Figure 2 herein.

[0068] Step S402, send an addressing request to the plurality of slave devices.

[0069] In some optional embodiments, a binary addressing method can be adopted to broadcast a random address conforming to the communication protocol of the DALI to the plurality of slave devices to implement step S402.

[0070] Specifically, the random address can be broadcasted by the following operation steps: Step S4021, dividing the random address conforming to the communication protocol of the DALI into a set number of random address bytes.

[0071] Specifically, the random address conforming to the communication protocol of the DALI can be a 24-bit binary number. The set number can be 3. The master device can divide the 24-bit data into 3 random address bytes according to each 8-bit group, and can process from the highest random address byte.

[0072] For example, a 24-bit binary number 101011001111000101010011 can be divided into 3 random address bytes 10101100, 11110001 and 01010011 according to each 8-bit group.

[0073] Step S4022, sending a first command including a first comparison value of the current random address byte to the plurality of slave devices from the highest random address byte.

[0074] In some optional embodiments, in the binary addressing process, the master device adjusts the 3 random address bytes in step S4021 in turn to obtain a 24-bit random address sent to the slave device, which is referred to as a 24-bit random address including the current random address byte as the first comparison value. The master device sends a first command including the first comparison value to the plurality of slave devices.

[0075] For example, the master device divides the 24-bit data into 3 random address bytes and processes from the highest random address byte.

[0076] Step S4023, adjusting the first comparison value to update the first command based on the first response information of the plurality of slave devices to the first command, until a unique slave device responds to the updated first command.

[0077] The slave device compares its own random address with the first comparison value including the current random address byte, and if the corresponding address byte of the random address of the slave device is the same as the current random address byte, the first response information returned by the slave device to the master device is a YES signal.

[0078] According to the reply of the slave device, the host device adjusts the first comparison value from the highest bit of the random address byte until the only slave device responds to the updated first command.

[0079] In step S4024, the only slave device responding to the updated first command is set to be in a mute state.

[0080] When the only slave device responds to the updated first command, the random address of the slave device is determined as the first comparison value corresponding to the updated first command. Thus, after the unique random address of a slave device is determined, the slave device is set to be in a mute state and does not respond to the addressing request in the current round of lighting device detection.

[0081] In step S4025, the first command is iteratively updated until no slave device responds to the first command.

[0082] According to the above operation steps, the host device compares and adjusts the three random address bytes in sequence, and finally determines the 24-bit random address of each unassigned address slave device.

[0083] In step S403, when the feedback information of the slave device responding to the addressing request is detected, the number of slave devices connected to the host device is counted, wherein the feedback information is used to represent that the device address of the slave device sending the feedback information matches the random address carried in the addressing request.

[0084] In some optional embodiments, the feedback information is the response information of the slave device sending the unique random address to the unique random address sent by the host device.

[0085] Specifically, when the slave device receives the unique random address sent by the host device and matching the current random address of the slave device itself, the slave device sends the response information of the unique random address to the host device. The feedback information here is the response information of the unique random address, and the unique random address is a 24-bit random address. Therefore, the feedback information here is essentially different from the response information of the slave device responding to the short address sent by the host device in the related art.

[0086] In some optional embodiments, step S403 can include: In step S4031, when the host device and the plurality of slave devices are controlled to enter the device number checking mode, the number of slave devices is set to 0, or the counting of the number of devices is started when the feedback information of the slave device responding to the addressing request is detected for the first time.

[0087] The two operation modes in step S4031 can be implemented by a count function or the like, and the difference lies in the trigger node of counting and the initial value of counting. In actual application, selection and configuration can be made according to actual requirements, and the present application does not make specific limitation thereto.

[0088] In step S4032, when the feedback information of the slave device responding to the addressing request is detected, the device quantity is updated based on the current device quantity plus one.

[0089] In step S404, when the feedback information of the slave device responding to the addressing request is detected, the slave device is configured with a short address for communication with the master device.

[0090] For details, reference can be made to the above Figure 2 S209 of the embodiment shown in the above

[0091] In step S405, when the addressing request indicates that the master device completes the addressing operation, whether the quantity of the slave devices exceeds the limit is determined based on the relationship between the device quantity and the first threshold.

[0092] If the master device broadcasts the addressing request carrying the smallest random address, and no feedback information of any slave device is received within a set time, it is determined that the master device completes the addressing operation.

[0093] Here, the smallest random address means that the random address needs to be sent to the slave device, so that the slave device compares its own random address with the received random address. When the random address of the slave device is smaller than the received random address, YES is returned to the master device, and when the random address of the slave device is not smaller than the received random address, NO is returned to the master device.

[0094] In some optional embodiments, when the device quantity is greater than the first threshold, it is determined that the device quantity of the slave devices connected with the master device exceeds the limit, and the excess quantity is the difference between the device quantity and the first threshold.

[0095] If the device quantity exceeds the limit, steps S406 and S407 are executed after step S405.

[0096] In some optional embodiments, when the addressing request indicates that the master device completes the addressing operation, if the device quantity is less than or equal to the first threshold, it is determined that the device quantity of the slave devices connected with the master device meets the communication protocol of the digital addressable lighting interface.

[0097] If it is determined that the device quantity of the slave devices connected with the master device meets the communication protocol of the digital addressable lighting interface, the lighting device detection method of the embodiment of the present application can be ended after step S405.

[0098] In the present embodiment, a lighting device detection method is provided, which can be used in the host device of the lighting system as described above, the lighting system comprising a host device and a plurality of slave devices, the host device and the slave devices communicate with each other through a digital addressable lighting interface, Figure 5 is a flow chart of the lighting device detection method according to an embodiment of the present application, as shown in Figure 5 , the flow comprises the following steps: Step S501, sending an addressing request to the plurality of slave devices.

[0099] In some optional embodiments, the addressing request carries a unique random address conforming to the communication protocol of the digital addressable lighting interface based on the dichotomous addressing mode. When receiving the addressing request, the slave device compares its own random address with the received unique random address. Based on the specific configuration of the addressing operation, when the slave device's own address is less than the unique random address, the slave device feeds back first response information corresponding to the addressing request to the host device, when the slave device's own random address is greater than or equal to the unique random address, the slave device feeds back first response information that the slave device's random address does not match the addressing request to the host device.

[0100] The host device adjusts the unique random address broadcast to the slave device through the bus conforming to the digital addressable lighting interface protocol based on the first response information of the slave device, to determine the random address of each slave device.

[0110] Step S602, start the silent mode.

[0111] Specifically, after the silent mode is started, the host device no longer performs other operation steps other than the necessary operation steps of device number detection.

[0112] Step S603, DALI device suspends activity.

[0113] Here, the DALI device is the slave device that communicates with the host device through a DALI protocol compliant interface. Here and in other descriptions of the present solution, the slave device can be connected to one or a group of lighting luminaires, and the slave device can control the lighting luminaires based on instructions received from the host device.

[0114] Step S604, clear short address.

[0115] Specifically, the DALI device clears the short addresses stored by the DALI device before the current time, ensuring that the short address allocated by the host device to the slave device after this operation step is completely new and conflict-free.

[0116] Step S605, initialize the DALI device.

[0117] Specifically, the DALI device can be controlled to perform initialization operations so that the DALI device is in an initial state that can perform address allocation and other operations.

[0118] Step S606, initializing random addresses.

[0119] Specifically, the random addresses of the DALI devices are initialized, which is the basis for subsequent binary comparison of the random addresses, and each device generates a unique random address.

[0120] Step S607, binary comparison of the random addresses.

[0121] Step S608, determining a unique random address of a slave device, counting the number of slave devices connected to the master device, and determining whether the binary comparison of the random addresses is completed.

[0122] If yes, the addressing operation of the DALI devices is completed, the number of slave devices is obtained, and step S612 is performed. If no, step S607 is returned.

[0123] Step S609, writing a short address.

[0124] Specifically, in the process of addressing the DALI devices by the master device using the binary comparison of the random addresses, a short address can be written for the DALI device addressed by the master device, and the DALI device addressed by the master device in each round of addressing process is usually the DALI device with the smallest random number. The individual short address addressing range in the DALI protocol is generally 0-63.

[0125] Step S610, exiting the operation.

[0126] After the short address writing is completed, the corresponding DALI device exits the addressing and short address writing operation state.

[0127] Step S611, address checking.

[0128] Step S612, determining whether the number of devices counted in step S608 is greater than a first threshold. If yes, step S613 is performed. If no, step S614 is performed.

[0129] Step S613, issuing a prompt information of the DALI device out of limit, and the number of the DALI devices out of limit is the difference between the number of devices counted in step S608 and the first threshold.

[0130] Step S614, determining that the number of DALI devices meets the requirement of the number of slave devices of the digital addressable lighting interface.
