Description

Technical Field

[0001] This invention relates to the field of intelligent lighting technology, and more specifically to a method for group control of luminaires based on many-to-many motion sensors and DALI drivers. Background Technology

[0002] With the development of lighting technology, motion sensors, as a device node in intelligent lighting DALI control systems, play a crucial role in energy conservation, emission reduction, and on-demand lighting. Controlling luminaires via motion sensors typically employs a one-to-one or one-to-many group control scheme, meaning one motion sensor controls one luminaire or multiple luminaires simultaneously. However, the sensing range of a single motion sensor is limited. In larger or specific lighting control schemes, multiple motion sensors need to be deployed to cover all or different areas of personnel. Traditional technologies cannot effectively achieve simultaneous control of a group of luminaires by multiple motion sensors. This is because when multiple motion sensors coordinate control, the timing of the sensor signals collected by each sensor differs, leading to overlap in the sent commands and causing confusion in the control switch signals. Using a DALI host to control and coordinate multiple motion sensors requires pre-programming and configuration on a PC in the backend system, pre-setting control functions. Therefore, the additional equipment cost is high, and professional technicians are needed for equipment installation, system configuration, and subsequent maintenance. Therefore, how to develop an automatic sensing and control method for multiple lamps by multiple sensors based on DALI lighting drivers that does not require the installation, configuration, and debugging of background system equipment, i.e., that is, that the lamps and sensors can run automatically after installation and power-on, is a direction that needs to be studied by those skilled in the art. Summary of the Invention

[0003] The present invention aims to provide a lighting control method based on many-to-many motion sensors and DALI drivers, which can simplify the sensor lighting system and overcome the problem of chaotic switching signals when multiple motion sensors are controlled.

[0004] The technical solution adopted is as follows:

[0005] A method for group control of lighting fixtures based on many-to-many motion sensors and DALI drivers includes the following steps: Step 1: Connect at least two motion sensors and at least two DALI lighting fixture drivers in parallel on a control data line; Step 2: Select one motion sensor from the at least two motion sensors, and when a sensing signal is received, send a pre-stored instruction sequence to each DALI lighting fixture driver on the control data line via DALI broadcast using the selected motion sensor.

[0006] A preferred embodiment is that step 2 includes: step A1: system initialization, where one of the at least two motion sensors is randomly selected as the master sensor and the remaining motion sensors are selected as slave sensors; step A2: when a slave sensor receives a sensing signal, the slave sensor sends a notification command to the master sensor; when the master sensor receives a sensing signal or a notification command, it sends a pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0007] More preferably, step A2 further includes: when the main sensor receives a sensing signal or notification command, clearing the currently unsent command sequence, and retransmitting the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0008] Another preferred embodiment is that step 2 includes: step B1: setting one of the at least two motion sensors as the master sensor using a DIP switch, and setting the remaining motion sensors as slave sensors using a DIP switch; step B2: when the slave sensor receives a sensing signal, the slave sensor sends a notification command to the master sensor; when the master sensor receives a sensing signal or a notification command, it sends a pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0009] More preferably, step B2 further includes: when the main sensor receives a sensing signal or notification command, clearing the currently unsent command sequence, and retransmitting the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0010] Another preferred embodiment is that step 2 includes: step C1: when a motion sensor receives a sensing signal, it sends a clear command to each of the other motion sensors through the control data line and sends a pre-stored command sequence to each DALI lighting driver through DALI broadcast; step B2: when the other motion sensors receive the clear command, they clear the command sequence that has not yet been sent.

[0011] More preferably, step C1 further includes: when at least two motion sensors receive sensing signals simultaneously, randomly selecting one of the motion sensors to send a clearing command to each of the other motion sensors via a control data line.

[0012] More preferably, in the above-described method for controlling lighting fixtures based on many-to-many motion sensors and DALI drivers, the at least two motion sensors include at least one of microwave motion sensors and PIR motion sensors.

[0013] More preferably, in the above-mentioned lighting group control method based on many-to-many motion sensors and DALI drivers: the at least two motion sensors include at least one of 2.4G microwave motion sensors and 5.8G microwave motion sensors.

[0014] Compared with existing technologies, this invention realizes an automated programmable control process based on signal collection, broadcasting, processing, and unified command execution after multiple motion sensors are triggered. Ultimately, one motion sensor, after autonomous information exchange, broadcasts a unique command to multiple DALI lighting drivers, enabling a many-to-many lighting control method. This solves the problem of secondary equipment configuration and manpower required when controlling multiple motion sensors, avoids chaotic switching signals, and achieves plug-and-play functionality without the need for external equipment or secondary configuration systems. Installation is simple, and installation and equipment investment costs are low. Attached Figure Description

[0027] like Figure 1-8 As shown:

[0028] A method for controlling a group of lamps based on multiple motion sensors 1 includes the following steps: Step 1: Connecting at least two motion sensors 1 and at least two DALI lamp drivers 2 in parallel on a control data line 3; Step 2: Selecting one motion sensor 1 from the at least two motion sensors 1, and upon receiving a sensing signal, sending a pre-stored instruction sequence to each DALI lamp driver 2 on the control data line 3 via DALI broadcast using the selected motion sensor 1.

[0029] By adopting the above technical solution, compared to... Figure 3 The existing DALI control system shown does not require the installation of a further DALI host, reducing equipment costs and eliminating the need for professional personnel to operate it.

[0030] Example 1:

[0031] like Figure 4 As shown: 12 light fixtures are arranged in a 3x4 matrix array in the room. There are 4 motion sensors, with their probes located at the 4 corners of the room.

[0032] The control process is as follows:

[0033] Step 1: Power on and initialize the system. Select the motion sensor located in the lower right corner of the room as the master motion sensor, and set the other 3 motion sensors as slave sensors.

[0034] Step 2: When a person enters the room from the lower right, the main sensor detects the signal triggered by the person and sends a pre-stored instruction sequence to each DALI lamp driver on the control data line via DALI broadcast; each lamp is then switched on synchronously according to the predetermined program.

[0035] Step 3: The person moves from the lower right of the room to the upper left of the room, leaving the sensing position of the main sensor probe. At this time, the probe located in the upper left of the room detects the sensing signal triggered by the person and sends a notification command to the main sensor.

[0036] Step 4: The main sensor receives the notification command, clears the currently unsent command sequence, and resends the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0037] Step 5: After the personnel leave the room, the motion sensors do not receive any new sensing signals, and all lights 8 turn off synchronously after executing all command sequences;

[0038] Step 6: Standby mode, waiting for a new sensor signal.

[0039] Example 2:

[0040] The device connections in Example 2 are exactly the same as in Example 1. The control process in Example 2 is as follows:

[0041] Step 1: Power on and initialize the system. Set the motion sensor with its probe in the lower left corner of the room as the master motion sensor using the DIP switch, and set the other three motion sensors as slave sensors using the DIP switch respectively.

[0042] Step 2: When a person enters the room from the lower right, the sensor located at the lower right of the room detects the signal triggered by the person and sends a notification command to the main sensor.

[0043] Step 3: The main sensor receives the notification command and sends the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast. Each lamp then synchronously illuminates according to the predetermined program.

[0044] Step 4: When a person moves from the lower right to the lower left of the room, the main sensor detects the signal triggered by the person, clears the currently unsent command sequence, and resends the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0045] Step 5: After the personnel leave the room, the motion sensors do not receive any new sensing signals, and all lights 8 turn off synchronously after executing all instruction sequences.

[0046] Step 6: Standby mode, waiting for a new sensor signal.

[0047] Example 3:

[0048] The device connection in Example 3 is exactly the same as in Example 1. The control process in Example 3 is as follows:

[0049] Step 1: Personnel enter the room from the lower right. The motion sensor 1 located in the lower right of the room receives the sensing signal triggered by it. The sensor sends a clearing command to each of the other motion sensors 1 through the control data line and sends a pre-stored command sequence to each DALI lamp driver 2 through DALI broadcast.

[0050] Step 2: The person moves from the lower right of the room to the upper right of the room, leaving the sensing area of ​​the motion sensor 1 located in the lower right of the room; at the same time, the motion sensor 1 located in the lower right of the room receives the sensing signal it triggered, and sends a clear command to each of the other motion sensors 1 through the control data line.

[0051] Step 3: The motion sensor 1, located in the lower right corner of the room, receives a clearing command and clears the currently uncompleted command sequence.

[0052] Step 4: After the personnel leave the room, the motion sensors do not receive any new sensing signals, and all lights 8 turn off synchronously after executing all instruction sequences.

[0053] Step 5: Standby mode, waiting for a new sensor signal.

[0054] Example 4

[0055] like Figure 5 As shown: Six light fixtures are arranged in a 1x6 straight line in the corridor. There are three motion sensors, with their probes located at both ends and the middle of the corridor.

[0056] The control process is as follows:

[0057] Step 1: Power on and initialize the system. Select the motion sensor located on the far right of the corridor as the master motion sensor, and set the other two motion sensors as slave sensors.

[0058] Step 2: When a person enters the corridor from the right side, the main sensor detects the signal triggered by the person and sends a pre-stored instruction sequence to each DALI lighting driver on the control data line via DALI broadcast; each lighting fixture lights up synchronously according to the predetermined program.

[0059] Step 3: The person moves from the right side of the corridor to the left side of the corridor and leaves the sensing position of the main sensor probe. At this time, the probe is located on the left side of the corridor. The secondary sensor detects the sensing signal triggered by the person and sends a notification command to the main sensor.

[0060] Step 4: When the main sensor receives a sensing signal or notification command, it clears the currently unsent command sequence and resends the pre-stored command sequence to each DALI lamp driver on the control data line via DALI broadcast.

[0061] Compared to existing technologies, the technical solution of this application eliminates the need for an additional DALI host. Instead, the control node is placed on the motion sensor without modification, enabling coordinated control of multiple lighting drivers via DALI broadcasting. This significantly reduces equipment costs and offers the advantages of simple operation and no need for secondary host configuration.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
