The embodiment of the present disclosure provides a dazzle color synchronization method for a central light fixture, which may be applied to any electronic device with a display lamp, for example, a lighting device, or may also be a terminal device, where the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. In some possible implementations, the image processing method may be implemented by a processor calling computer readable instructions stored in a memory.
Fig. 1 shows a flowchart of a method for synchronizing glare of a luminaire according to an embodiment of the present disclosure, and as shown in fig. 1, the method for synchronizing glare of a luminaire includes:
s10: receiving first broadcast information of a first luminaire, wherein an identifier of the luminaire in the distributed luminaire system matches a time slot for transmitting the broadcast information;
s20: acquiring a first identifier of the first lamp in the first broadcast information, and determining the first lamp as a main lamp in response to the first identifier being smaller than a stored second identifier;
s30: and executing dazzling synchronization according to the synchronization information sent by the main lamp.
The dazzle color synchronization method for the lamps in the embodiment of the disclosure may be applied to a distributed lamp system, where the distributed lamp system may include a plurality of lamps, and the lamps may be any lamps with display effects, such as LED lamps on a circuit board, and a plurality of indoor illuminating lamps, and the disclosure is not limited in this respect. The lamps can realize network connection by using a wireless mesh (mesh) network, and can be respectively configured with corresponding identifiers, wherein the identifiers of the lamps are different. The identifier of the lamp in the embodiment of the present disclosure may be a number, and the identifier may be an identifier configured for the lamp by a wireless mesh router in the lamp.
Each luminaire in the distributed luminaire system may perform the broadcast of the identification information, and other luminaires may receive the broadcast information. In the embodiment of the present disclosure, taking the second lamp as an example for description, the second lamp may receive other lamps (such as the first lamp), where the first lamp may be any lamp except the second lamp.
The second luminaire may receive broadcast information of the first luminaire, that is, first broadcast information, the first broadcast information may include an identifier (first identifier) of the first luminaire, and in a case where the first broadcast information is received, the first identifier may be read from the first broadcast information. In addition, in the embodiment of the present disclosure, each luminaire may perform a broadcast operation in a different time slot, and the broadcast information may include an identifier of the luminaire.
In the embodiment of the present disclosure, matching the identifier of the lamp with the broadcast time slot of the corresponding broadcast information may include that the identifier of the lamp is the same as the time slot in which the lamp sends the broadcast information. For example, if the identification of the luminaire is n, the luminaire may send the broadcast information at the Tn slot. For example, a time frame may comprise a plurality of time slots, which may be respectively allocated to different luminaires for performing the transmission of the broadcast information of the luminaires.
That is, based on the configuration of the embodiment of the present disclosure, the luminaire may broadcast the information in the time slot matching the identifier, for example, the luminaire identified as 1 may transmit the broadcast information in the time slot T1, the luminaire identified as 2 may transmit the broadcast information in the time slot T2, and so on, the luminaire identified as n may transmit the broadcast information in the time slot Tn.
Based on the configuration, under the condition that the first lamp sends the first broadcast information in the corresponding first time slot, the second lamp receives the first broadcast information, can acquire the first identifier in the first broadcast information, can compare the stored second identifier with the first identifier, and if the first identifier is smaller than the second identifier, can determine the first lamp as the main lamp. By the method, the lamp with the smallest identification in the distributed lamp system can be determined as the main lamp, that is, the lamp which firstly sends the broadcast information can be determined as the main lamp according to the sequence of the time slots.
For example, the lamp identified as 1 transmits the broadcast information at the time slot T1, at this time, other lamps do not receive the broadcast information transmitted by other lamps, and at the same time, the identifier 1 is smaller than the identifiers of other lamps, and at this time, the lamp identified as 1 may be determined as the master lamp.
Or, in the case that the lamp identified as 1 does not transmit the broadcast information at the T1 time slot due to a fault, a network, a power outage, or other factors, the lamp identified as 2 may transmit the broadcast information at the T2 time slot, and at this time, the lamp identified as 2 may be the main lamp.
Under the condition that the main lamp is determined, synchronous display with the main lamp can be executed according to the synchronous information sent by the main lamp, and dazzle color synchronization is achieved. In the embodiment of the present disclosure, the first broadcast information broadcasted by the first lamp may include, in addition to the first identifier, synchronization information of the first lamp, where the synchronization information may include a display effect, a conversion frequency, and a current display state of the first lamp. The display states of the first lamp at different moments of the display effect are different, and the conversion frequency represents the reciprocal of the holding time of each display state. That is to say, in the case of obtaining the first broadcast information, the second luminaire may directly obtain the synchronization information of the first luminaire, and in the case of determining the first luminaire as the master luminaire, the synchronization display may be directly established with the first luminaire according to the synchronization information of the first broadcast information. Or, in the embodiment of the present disclosure, when the first luminaire is determined as the master luminaire, the first luminaire may send confirmation information to the first luminaire, where the confirmation information is used to indicate that the second luminaire determines the first luminaire as the master luminaire, and at this time, the first luminaire may send synchronization information of the first luminaire to the second luminaire, so that the second luminaire and the first luminaire are displayed synchronously.
In addition, in the embodiment of the present disclosure, when the second luminaire determines the first luminaire as the master luminaire, the broadcast operation is no longer performed in the second time slot matched with the second identifier of the second luminaire, that is, the second broadcast information including the second identifier is no longer sent in the second time slot, so that broadcast information in the network can be reduced, and meanwhile, the master luminaire is prevented from being repeatedly determined by other luminaires.
In addition, since the broadcast information of the master luminaire can be received after the master luminaire is determined, the second luminaire in the embodiment of the present disclosure can send the second broadcast information in the second time slot under the condition that the broadcast information of the master luminaire is not received within the preset time. That is, to prevent the failure of the main fixture to synchronize the display with the main fixture due to a failure of the main fixture or other factors, a reselection process of the main fixture may be automatically performed. The preset time may be set according to a requirement, which is not specifically limited by the present disclosure, and may be, for example, one cycle, or a sum of time slots of all the lamps.
In some possible embodiments, there may be a new lamp in the distributed lamp system, and for convenience of description, the third lamp is taken as the new lamp. The third luminaire may also have an identifier (third identifier), and the corresponding third luminaire may also perform a broadcast operation in a timeslot (third timeslot) matching the third identifier.
In this embodiment of the disclosure, a first lamp is used as a master lamp, if a third identifier of a newly added third lamp is greater than the first identifier, and a current time is before the first time slot or after the third time slot, the third lamp may determine the first lamp as the master lamp according to first broadcast information of the first lamp in the first time slot, if the current time is between the first time slot and the third time slot, the third lamp broadcasts third broadcast information in the third time slot, but other lamps may not use the third lamp as the master lamp because the first time slot of the current master lamp is before, and the first lamp broadcasts the first broadcast information during a next first time slot, and at this time, the third lamp may determine the first lamp as the master lamp according to the first broadcast information of the first lamp.
In addition, if the first identifier is larger than the third identifier, if the current time is between the first time slot and the third time slot, the first lamp may send the first broadcast information in the first time slot, at this time, because the third identifier is smaller than the first identifier, the third lamp may not determine the first lamp as the master lamp, when the third time slot is reached, the third lamp broadcasts the third broadcast information including the third identifier, and under the condition that the other lamps receive the third broadcast information, the third lamp may be determined as the master lamp, thereby implementing the switching of the master lamp.
If the current time is located before the third time slot or after the first time slot, and the time reaches the third time slot, the third lamp broadcasts third broadcast information including the third identifier, and the other lamps can determine the third lamp as the main lamp under the condition that the other lamps receive the third broadcast information, so that the switching of the main lamp is realized.
By the embodiment, the main lamp in the distributed lamp system can be determined, and the main lamp can be re-determined when a new lamp is added or the main lamp fails.
The following illustrates the processes of embodiments of the present disclosure,
the traditional dazzle color synchronization system depends heavily on a central node (gateway), and dazzle color synchronization of child nodes is realized through a synchronization frame of the gateway. Once BLE MESH or other gateway-less application scenarios are encountered, the dazzle color function cannot be implemented.
The disclosed embodiments provide synchronization for three situations: 1) an initial network cooperation process; 2) adding a new node into the cooperative process; 3) and (3) powering off or disconnecting the leader node, and then electing the leader node, wherein the following nodes refer to lamps.
When all devices (mesh route and lamps) are powered on simultaneously, a leader node (main lamp) needs to be elected in the whole network, and the electing algorithm is as follows:
the node with the number (identification) of n synchronizes the information to other nodes in Tn time slots in a broadcasting way; at any time, when a Tm node receives a Tn node broadcast, and m > n is satisfied, the m node adjusts its own pace to be synchronized with the n node, and does not broadcast at the Tm time slot until no other node broadcast is received within a timeout Tout.
By adopting the rule, all nodes can negotiate the leader node in a very short time, and a large amount of broadcast in the network cannot be caused. Fig. 2 illustrates a network cooperation process of each node, i.e., a selection process of a master node according to an embodiment of the present disclosure. At time T1, the broadcast message of node No. 1 is received by all other nodes, and other nodes elect node No. 1 directly as leader nodes. At times T2, T3, T4, and T5, no more nodes broadcast, and when the loop is to T1, node No. 1 broadcasts again.
Following the above algorithm, the new node joins the cooperation process as follows: (assume the original leader node is n and the newly added node is m); if n is less than m, if the time slot is before Tn or after Tm, the new node will acknowledge the n node as a leader at the time slot of Tn; if the time slot is after Tn and before Tm, the m node will broadcast once in the Tm time slot, but will grant the leader status of the n node in the next Tn time slot; if m < n, if the time slot is before Tn and after Tm, the new node receives the broadcast of the n node in the Tn time slot and does not admit the leader status, and the m node sends out the broadcast in the Tm time slot, at this time, the n node gives up the leader status, and the m node becomes a new leader; if the time slot is after Tn or before Tm, the m node directly becomes a new leader in the Tm time slot, and the n node gives up the leader.
Following the above algorithm, when the leader node is disconnected (assuming that the original leader node is n, and the nodes numbered the second time less than n are m): the m nodes unify the nodes of the whole network in the Tm time slot, establish leader status, and then do not broadcast by other nodes.
In summary, in the embodiment of the present disclosure, the master luminaire may be determined according to the identifier of the luminaire in the received broadcast information, and if the first luminaire identifier in the broadcast information received by the second luminaire is smaller than the stored second identifier, the second luminaire may determine the first luminaire as the master luminaire and perform the synchronous color-dazzling display with the first luminaire. Through the configuration, a gateway or other auxiliary devices are not required to be arranged, the main lamp can be determined through the identification of the lamp, and the colorful synchronization between other lamps and the main lamp is realized. In addition, the identification of the lamp is matched with the time slot for sending the broadcast information in the embodiment of the disclosure, so that the broadcast operation can be executed under the lamp with a small identification, a large amount of information storm negotiation is avoided, and the confusion caused by the determination process of the main lamp can be avoided.
In addition, even if the main node fails, a new main node can be quickly determined, and the method has quick self-healing capability and quick cooperation capability.
