[0059] The present application is illustrated by way of the following detailed description based on of the accompanying drawings. It should be noted that illustration to the embodiment in this application is not intended to limit the invention.
[0060] Referring to FIG. 1 , a synchronous lighting system in this embodiment comprises two synchronous lighting devices'! 00, a timing device 400 and a control device 600. The synchronous lighting device 100 comprises a first wireless networking module 101, a lighting control module 102 and a light source module 103. The timing device 400 comprises a timing control module 401 , a second wireless networking module 402 and a timing power supply module 403. All the first wireless networking modules101, and the second wireless networking module 402 form a communication network 500.
[0061] The number of synchronous lighting devices can be set according to the needs. In addition to two, there can be more than two, with the same structure. The lighting control module 102 is connected with the light source module 103, the input can be powered by 24 V or 12 V, and the output is connected with the light source module 103 and the first wireless networking module 101. The lighting control module 102 is mainly used to receive the control signal of the first wireless networking module 101, and control the light source module 103 to adjust the lighting parameters such as brightness and color temperature.
[0062] The control device 600 connects and transmits the lighting configuration data to the communication network 500, the timing device 400 obtains and periodically broadcasts the time stamp to all the synchronous lighting deviceslOO through the communication network 500, and all the synchronous lighting device 100 obtain the lighting configuration data through the communication network 500.
[0063] The control device 600 is used to transmit the lighting configuration data to the communication network 500, and the lighting configuration data is used to control the synchronous lighting device, including but not limited to brightness, color temperature, lighting schedule, time stamp and sensor sensitivity. Further, the lighting configuration data comprises at least one of brightness, color temperature, lighting schedule, time stamp and sensor sensitivity. [0064] In addition to the time stamp, other lighting configuration data will rarely change after confirmation, while the time stamp will be inaccurate due to the power failure of the synchronous lighting device. It is inconvenient to calibrate the synchronous lighting device through the control device 600 after each power failure of the synchronous lighting device. However, the Internet control not only needs to increase the connection equipment, but also has the risk of information leakage. Therefore, in the present embodiment, the timing device 400 periodically broadcasts time stamps to all synchronous lighting devices'! 00 to synchronize the time stamps of all synchronous lighting devices in the communication network 500, so as to keep the time stamps of all synchronous lighting devices in the communication network 500 synchronized.
[0065] The control device 600 can be a mobile phone, a remote controller and other control devices. Further, the control device 600 of the embodiment is a mobile phone, which can connect and transmit the lighting configuration data to the communication network 500 by installing a special lamp control app.
[0066] The timing power supply module 403 is used to supply power to the timing device 400. In order to maintain continuous power on and avoid inaccurate time stamp caused by power failure, the timing power supply module 403 of the present embodiment comprises a power supply battery (not shown in the diagram) .The power supply battery can continuously supply power to the timing control module 401 and maintain the time stamp record. At the same time, in order to give consideration to universality, the timing power supply module 403 of another embodiment also comprises a plug (not shown in the diagram) .The plug can be connected with an external power supply to supply power to the timing control module 401 or to charge the power supply battery. The time service control module 401 can automatically judge winter time and summer time according to the state, and make corresponding adjustment. The existing products can be used for power supply battery and plug, which will not be discussed here.
[0067] In order to prolong the service life of the power supply battery, which is generally more than 10 years, and to avoid replacement, the second wireless networking module 402 of another embodiment is constructed to operate periodically.
[0068] In order to further reduce energy consumption and prolong the service life of the power supply battery, the second wireless networking module 402 of another embodiment is constructed to cannot be connected in the communication network 500.
[0069] In order to find as few devices as possible, and in order to prevent others from discovering and damaging the communication network 500, the communication network 500 of another embodiment, in which one of the first wireless networking modules 101 is constructed to be connectable in the communication network 500, and the other first wireless networking modules 101 are constructed to cannot be connected in the communication network 500. Generally, the number of the first wireless networking modules 101 be connectable settings is 1 , and the number of the first wireless networking modules 101 cannot be connected settings can be more than 1.
[0070] In the communication network 500 of another embodiment, the all first wireless networking modules101 and the second wireless networking module 402 adopt Bluetooth module. The communication network 500 is a mesh network, and the Bluetooth mesh ad hoc network does not need a gateway, and can be directly connected with the mobile phone, so as to minimize the number of devices in the network, with low cost and low power consumption.
[0071] Referring to FIG. 2, a synchronous lighting system in another embodiment, the synchronous lighting devicelOO also comprises a sensing module 700.The sensor module 700 can transfer the feedback information from the outside to the lighting control module 102, thus changing the parameters in the lighting configuration data to achieve a more suitable lighting effect.
[0072] A synchronous lighting system in another embodiment, the sensing module 700 comprises at least one of color recognition sensor 701 , temperature sensor 702 and microwave sensor 703. The microwave sensor 703 can sense a person approaching, control the lighting control module102 to turn on the light when the person approaches, and then dim the light after delaying for a period of time when no one is detected. The temperature sensor 702 can collect the ambient temperature in the freezer and display it through the digital display tube. The color recognition sensor 701 can automatically identify whether the goods on the freezer shelf are meat or other goods, thereby adjusting the light source module 103 to select the light color of meat or the light color of non meat. [0073] Referring to FIG. 3, the time stamp synchronization mechanism process of the timing device 400 in this embodiment is as follows:
[0074] The control device 600 (such as a mobile phone) will broadcast the current time stamp to all devices in the communication network 500 after searching for the first wireless networking module 101 that can be connected and connecting the communication network 500. As long as the wireless networking module of the device is powered on, the time stamp will be received.
[0074] Since the timing device 400 is powered by battery, it needs to work in low power consumption mode. Therefore, the power supply of the second wireless networking module 402 needs to be controlled by the timing control module 401 , the second wireless networking module 402 periodically powers on, sends instructions, and then cuts off the power. When the second wireless networking module 402 is in the power-off state, it is unable to receive any instructions from the communication network 500, and at this time, the control device 600 cannot directly send the time stamp to the timing device 400. Here, the first wireless networking module 101 that can be connected is used as the transfer, and the specific mechanism is as follows:
[0075] The timing control module 401 controls the second wireless networking module 402 the power on, sends instructions to the first wireless networking module 101 that can be connected, and inquires about the time stamp. If the first wireless networking module 101 has received a new time stamp sent by the control device 600, all the devices in the communication network 500 and the second wireless networking module 402 receive the time stamp and then power off and wait for the next power on. If the first wireless networking module 101 has not received the new time stamp sent by the control device 600, it will send an instruction to tell the timing device 400, and the timing device 400 will broadcast the time stamp stored by the time service control module 401 to all the devices in the communication network 500 through the second wireless networking module 402 (the time stamps of all devices are synchronized). After broadcasting, the power of the second wireless networking module 402 is cut off, waiting for the next power on.
[0076] In the communication network 500, in addition to the timing device 400, a timing task synchronization mechanism is set between the synchronous lighting deviceslOO. The process is as follows: [0077] In the communication network 500, each lighting control module except the timing device 400 saves a timing task table, and synchronizes it regularly to keep consistent. Each lighting control module will calculate a check value (CRC16 cyclic redundancy check) according to the currently saved timing task.
[0078] The first wireless networking module 101 that is connectable will regularly broadcast the check value to the first wireless networking module101 that cannot be connected. If its own check value is inconsistent with the received check value, its lighting control module 102 will broadcast the command to the first wireless networking module 101 that is connectable to request the synchronization task table. After receiving the request through the first wireless networking module 101 that is connectable, broadcast the check value to the first wireless networking module101 that cannot be connected, the corresponding lighting control module 102 performs analytical synchronization. In this way, the timing task table is synchronized, and then each device performs corresponding actions according to its own timing task table.
[0079] Referring to FIG. 4, the synchronous lighting control method in this embodiment adopts the synchronous lighting system of the above-mentioned embodiment, including the following steps:
[0080] 001.All the first wireless networking modulesl 01 and the second wireless networking module 402 form a communication network 500;The second wireless networking module 402 is constructed to cannot be connected in the communication network 500; one of the first wireless networking modules 101 is constructed to be connectable in the communication network 500, and the other first wireless networking modules 101 are constructed to cannot be connected in the communication network 500;
[0081] 002. The control device 600 connects and transmits the lighting configuration data to the communication network 500;The control device 600 is connected to the communication network 500 by searching for a first wireless networking module 101 that can be connected, and broadcasts the lighting configuration data including the time stamp in the communication network 500.When the control device 600 uses a mobile phone, after the app in the mobile phone is started, it will connect to the corresponding communication network 500. After connecting, the app will obtain the time of the intelligent device, convert the time into Greenwich Mean Time and send it to the devices in the communication network 500, so that the device will not be affected by the time zone. The purpose of the synchronous timestamp is to give the latest time stamp to the timing device 400, but the timing device 400 is powered on periodically and often sleeps (in order to reduce energy consumption), so it synchronizes the time stamp to other devices, and then synchronizes it to the timing device 400 through other devices, using the broadcast command.
[0082] 003. The timing device 400 acquires the time stamp in the communication network 500 and stores or updates it;
[0083] 004. The timing device 400 periodically broadcasts the latest time stamp to all synchronous lighting devices'! 00; The second wireless networking module 402 is constructed to be periodically powered on;
[0084] 005. All the synchronous lighting devices'! 00 obtain the lighting configuration data through the communication network 500.
[0085] Referring to FIG. 5, the synchronous lighting control method in another embodiment, step 003 and step 004 are carried out in the same cycle. In a working cycle, whether to carry out step 003 is judged first. The steps of judging whether to carry out step 003 are as follows:
[0086] 0031.The timing device 400 periodically powers on the second wireless networking module 402;
[0087] 0032. The timing device 400 inquires the synchronous lighting device 100 whether there is a new time stamp. If there is a new time stamp, go to step 0033, if not, step 0034;
[0088] 0033. If the synchronous lighting device 100 has a new time stamp, broadcast the time stamp in the communication network 500, and then proceed to step 003;
[0089] 0034. The synchronous lighting devicelOO has no new time stamp, and then proceed to step 004.
[0090] Step 005 comprises:
[0091] 0051.Broadcast synchronous lighting configuration data through the control device 600;
[0092] 0052. The timing device 400 broadcasts a synchronous time stamp; [0093] 0053. The synchronous lighting device 100 and the synchronous lighting device 200 mutually synchronize with each other.
