_^ The method of process stream (initial setting method)

This embodiment also provides an initial setting method applicable to the above-mentioned lighting system.

Referring to FIG. 4, the initial setting method provided by this embodiment specifically includes the following steps:

S01. Power on. After the user purchases and installs, the power of each light unit 10 and the remote controller 20 is turned on.

502. Initialization

Each light unit 10 and the remote controller 20 read the initial data in the firmware, and initialize the light unit settings.

503. Network construction

Each optical unit 10 and the remote controller 20 enter the pairing waiting mode. In the pairing waiting mode, the Bluetooth communication module 10BLE of the optical unit 10 communicates with each other in the short-distance broadcasting mode. In the short-distance broadcasting mode, the signal strength threshold is set to be lower than the signal strength. The intensity threshold signal will be ignored to reduce the possibility of the light unit 10 to be paired being mistakenly bound by the network of other lighting systems.

In this embodiment, the optical unit 10 can detect the action (or switch state) of its mechanical switch 108, and in response to the foregoing action or state meeting a preset condition, the optical unit 10 is forcibly initialized. Through the above method, even if some of the optical units 10 are mistakenly bound by other networks, their mechanical switches 108 can be used to trigger the initialization of the optical units 10 to force the optical units 10 that have been mistakenly bound to be unbound from other networks.

For example, the action of repeatedly opening and closing the mechanical switch 108 within a certain period of time (or detection of repeated switching of the switch state) can be used as a trigger action for the initialization of the light unit 10. In response to detecting the trigger action, the light unit 10 will be forcibly It is initialized to the factory state and removed from the BLE Mesh network that has been paired. In some embodiments, in response to separate confirmations from different rooms or areas, the optical units 10 in these different rooms or areas are added to the same network.

S04 confirms the network construction result.

The user can obtain the network construction result through the indications of the light unit 10 and the indicator lights 110, 210 on the remote control 20. If the light unit 10 and the remote control 20 are paired, the indicator lights 110 and 210 on the light unit 10 and the remote control 20 will notify the user of the network construction result by means of flashing behavior, on and off, flashing frequency, and breathing light changes.

If the user confirms that the network construction is successful, then go to the S05 grouping step. In this embodiment, after the network is successfully established, the indicator light 110 will flash once and then be lit, as a predetermined prompt manner.

If the user cancels the network construction result, return to S01 power-on step.

S05 grouping.

The optical unit 10 enters the group setting mode automatically or in response to an instruction from the remote controller 20. In the grouping setting mode, any suitable way can be used to group the light units 10, and the multiple light units 10 in the lighting system are organized into several control groups. S06 confirms the grouping result.

If the user confirms the grouping result, the initial setting is completed;

If the user cancels the grouping result, go to S05 grouping step.

After the initial setting is completed, when the toggle switch 200 on the remote controller 20 is toggled to the first gear position (group one), several light units 10 in the first control group la corresponding to the gear position can be used as Group control as a whole. In addition, in some implementation manners, other controls of the remote controller 20 may also be used to implement the operations of ungrouping the optical units 10 in the group (still in the network) and unbinding the network. For example, when the toggle switch 200 is toggled to the first gear (group one), if a predetermined action of the user on the remote control is detected, the first control group la can be cancelled. The network unbinding operation can be activated and implemented at the optical unit 10 by using mechanical components installed on the optical unit 10 to initialize a single optical unit and unbind from the network; it can also be performed in groups from the remote control 20, for example, The toggle switch 200 is toggled to the first gear (group one), and through a predetermined action, all the optical units 10 in the first control group la are initialized and unbound from the network.

Method flow (single lamp control method)

For systems that have been grouped by the above initial setting method, this embodiment also provides a control method for implementing single lamp control by using the remote controller 20 capable of grouping control. Referring to FIGS. 5 and 6, the left side of FIG. 5 shows the actions performed by the remote controller 20 in the single lamp control method, and the right side of FIG. 5 shows the actions performed by the light unit 10 in the single lamp control method. Specifically, the control The method includes the following steps:

In the preparation state, the light unit 10 is in a normal working state, and the remote controller 20 is in a non-working state. Take, for example, that the group control 200 of the remote controller 20 is dialed in the gear position corresponding to the first control group la (the "group one" gear position).

S07 Single lamp control selection step, in response to the user's long-press operation of the radio button 204, the remote controller 20 entering the radio mode and each light unit 10 in the same control group establish a Bluetooth communication connection one by one.

When a predetermined action of the user on the radio button 204 is detected, the remote control 20 and the same control group are triggered (in this embodiment, since the grouping control 200 is located at a position corresponding to the first control group la, the same control group is Each light unit 10 in the first control group la) enters a single selection mode. In the single selection mode, the remote controller 20 will establish a Bluetooth communication connection with each light unit 10 in the first control group la one by one. In this embodiment, the action to trigger the entry into the radio mode is to press and hold the radio button for more than 3 seconds. In other embodiments, other actions may also be set as the trigger action. The sequence in which the Bluetooth communication connection is established with each optical unit 10 can be adjusted according to actual conditions. In some embodiments, the signal strength of the Bluetooth communication connection between each light unit 10 and the remote control 20 can be detected in the grouping step S05, and the remote control 20 and the light unit 10 can be generated after sorting according to the signal strength. Control the sequence of establishing Bluetooth communication connection one by one in the selection step. In some embodiments, the order of the MAC address may also be used to establish the order of Bluetooth communication connections.

In S08 prompt step, in response to the corresponding current light unit 10 establishing a connection with the remote controller 20, the indicator light 110 (that is, the prompt part) flashes (that is, a prompt message is issued).

The indicator light 110 on the light unit 10 can remind the user of the light unit 10 currently connected to the remote control 20, and the user can determine whether the connected light unit 10 is the light unit 10 that the user intends to implement single-lamp control according to the prompt information. And use the interaction with the remote controller 20 to switch between the light units 10 until the target is selected. The target selection process is achieved through S09 selection steps:

In the S09 selection step, by continuously pressing the radio button 204 for multiple times, switch between multiple light units 10 in the same control group until the indicator light 110 of the light unit 10 to be controlled by the single light flashes.

In this embodiment, the light unit 10 to be controlled by the single lamp is selected in response to switching, that is, if a single pressing operation of the radio button 204 by the user is detected, the communication connection with the current light unit 10 is disconnected, And according to a predetermined sequence, a communication connection with the next optical unit 10 is established. In another embodiment of the present invention, an automatic switching method may also be adopted. For example, a communication connection with a certain optical unit 10 may be established when entering the single-selection mode, and the user may be notified of the connection status by the indicator light 110. Then, every preset time (for example, 5 seconds), the communication connection with the current optical unit 10 is automatically disconnected, and a communication connection with the next optical unit 10 is established according to a predetermined sequence. If the user observes that the indicator light 110 of the light unit 10 to be controlled by the single lamp flashes, the communication connection can be established directly via the feedback key 206. In still another embodiment of the present invention, a pair of buttons for user operation can also be provided on the remote controller 20, one of which can be selected in a predetermined order, and the other can be selected in a reverse order opposite to the predetermined order. , To improve selection efficiency through a pair of keys. In the above, the predetermined sequence and the selection method of the selection steps are not limited, and any other suitable methods can also be adopted.

In S10, the feedback confirmation step is to establish or cancel the communication connection of the optical unit 10 according to the detected operation result of the feedback key 206. The feedback button 206 of the remote control 20 is used to receive the user's confirmation result of the optical unit 10 selection. If the confirmation information is received, the current communication connection between the optical unit 10 and the remote control 20 is established, and the communication connection is maintained for receiving The user's single-lamp control instruction; if a cancellation message is received, go to S07 single-lamp control selection step, and re-establish a communication connection with each light unit 10 in the control group one by one.

S11 Single-lamp control step: Single-lamp control is performed on the single-lamp control light unit 10TBC with the established communication connection, and the adjustment of the single-lamp control light unit 10TBC is adjusted according to the single-lamp control command generated by the user through the operation of the dimming key 208 Optical parameters.

In this embodiment, the remote controller 20 has a dimming key 208, which can adjust the brightness of the light unit 10. In other embodiments of the present invention, the remote control 20 may also have other dimming functions, for example, between establishing the remote control 20 and the current light unit (ie, the single light control light unit 10TBC) associated with the current prompt message After the communication control is connected, the remote controller 20 can at least adjust one or more of the color temperature of the single-lamp control light unit 10TBC, the delayed light-off function, and the buzzer control function.

S 12 Setting saving step, if the confirmation message from the user is received, the dimming parameter of the single lamp control light unit 10TBC is changed and the modified dimming parameter is saved in the memory 10MEMO or the memory 20MEMO, and then the scene 1 and The factory settings of the dimming parameters corresponding to the second-class scene control 202 are modified.

S13 Scene generation step, based on the saved dimming parameters of each light unit 10 in the same control group, create a scene for the control group and save it in the memory 20MEMO.

In this embodiment, a scene generation module (not shown) is stored in the memory of the remote controller, and by reading and executing the scene generation module, the S13 scene generation step can be executed.

In some embodiments, the user can use the scene setting button (not shown) on the remote control 20 to enter the scene setting mode. After the light units in the control group whose dimming parameters need to be adjusted are all controlled by a single lamp, The final single lamp control result is determined, summarized and generated as a scene, and the scene is saved in the memory 20MEMO for the remote control 20 to use the scene control 202 to directly call in the subsequent control process to reproduce the user-defined scene setting set.

Through the above methods, the control method provided by this embodiment can utilize the remote controller 20 without a graphical user interface or with only a simple graphical user interface to realize grouping control and single lamp control for a complex lighting system. Moreover, in the single lamp control process, only a small number of light units 10 in the same group need to be selected, which is convenient for the user to complete the selection with fewer times. In addition, there are prompts during the selection process, which further improves the intuitiveness and speed of selection. Again In addition, a user-defined scene can also be generated based on the single lamp control result, and the scene control 202 of group control can be directly called.
