[0003] To meet the needs of urban infrastructure, there are more and more transportation stations connecting subway stations, airports, ports and train stations. Therefore, there are tunnels between these stations. Or in some countries, many buildings are also connected with tunnels. And the tunnel is a place where lights are always on during all working hours. For example, all these transportation tools will have a schedule, which means that people will go like waves. Either there are people in the tunnel from time to time, or there are almost no people staying or passing in the tunnel. Summary of the invention

[0043] First aspect of the implementation plan

[0044] In a first aspect of the embodiments a system for controlling a lighting fixture is provided.

[0045] Figure 1 is a diagram of a system for controlling lighting equipment according to an embodiment of the present disclosure.

[0046] like Figure 1 As shown, a system 100 for controlling lighting equipment includes a detection device 10 and a controller 20 .

[0047] The detection device 10 is configured to detect the number of people in the tunnel and track the movement of the people.

[0048] The controller 20 is configured to generate a control signal according to the detection result of the detection device, and the control signal is used to control the driver to drive the lighting equipment in a predetermined area of ​​the tunnel.

[0049] According to the first aspect of the embodiment, the situation where a person stays in a tunnel but the lights are dimmed can be avoided. And a large amount of energy can be saved at a lower cost. The person and the security personnel have a more comfortable experience and do not feel sacrificed for energy saving. And the security personnel no longer need to use a flashlight when patrolling.

[0050] In at least one embodiment, the tunnel is used to connect transportation stations or buildings. People will walk or stand or sit in the tunnel to wait for transportation or to reach their destination.

[0051] like Figure 1 As shown, the detection device is configured to detect the number of people in the tunnel, and when the number of people is less than or equal to a first threshold but not zero, track the movement of the people by using an artificial intelligence (AI) algorithm.

[0052] For example, the detection device 10 includes a detector 101, which can be a camera (but not limited thereto), which can be deployed at any position in the tunnel, for example, the camera can be deployed around the two entrances of the tunnel. The number of detectors is one or more. The camera can take some pictures (image frames) toward the tunnel. The detector can also include a processor, which can identify the personnel contained in the image frame by a common image recognition algorithm and count the number of personnel in the image frame. When the number of personnel is greater than the first threshold, the system maintains the current control mode, that is, all lights are always turned on. When the number of personnel is less than or equal to the first threshold but is not zero, the system activates "tunnel mode". The first threshold can be set as needed. For example, the first threshold can be set to 3, but is not limited thereto. Regarding the working principle of the detection device 10, reference can be made to the relevant field for more details.

[0053] When "tunnel mode" is activated, the detection device (detector) tracks the movement of people by using an artificial intelligence (AI) algorithm. In one example, the artificial intelligence (AI) pattern recognition algorithm can be a skeleton-based action recognition algorithm for locating the position of people in the tunnel, through which people with specific actions or gestures in the picture will be identified, for example, the movement (action or gesture) includes sitting, walking, standing, etc.

[0054] In at least one embodiment, when the detection device (detector 101) detects that a person is moving (walking), the controller 20 generates a first control signal; the first control signal is used to control the driver to dim the lighting equipment based on the movement of the person. For example, when the detection device (detector 101) detects that a person is moving (walking), the processor generates a first signal. The detection device 10 also includes a communication unit 102. The communication unit 102 is configured to send a first signal S1 to the controller 20 via wireless communication. In one example, the wireless communication can be Bluetooth communication. But not limited to this, for example, the wireless communication can be WIFI communication, etc.

[0055] In at least one embodiment, the first control signal is used to control the driver to dim lighting equipment above the personnel to a first predetermined level and to dim lighting equipment in other areas to a level dimmer than the first predetermined level. Figure 2 is a diagram showing the brightness of lighting equipment in a tunnel according to an embodiment of the present disclosure. Figure 2 As shown, the lighting equipment in the tunnel can be regarded as a rectangular area. The rectangular area will include a first number of parts, for example, the first number is equal to 4, but not limited to this. The first part is the area above the personnel. The second part is adjacent to the first part. The third part is adjacent to the second part, and so on. Therefore, the first control signal is used to control the driver to dim the lighting equipment in the first part to a first predetermined level and dim the lighting equipment in other parts (except the first part) to a level darker than the first predetermined level, where the closer to the first part, the higher the brightness, and the farther away from the first part, the lower the brightness. As shown Figure 2 As shown, the first control signal is used to control the driver to dim the lighting equipment in the first section to 90% of the (normal) brightness, dim the lighting equipment in the second section to 78% of the (normal) brightness, dim the lighting equipment in the third section to 55% of the (normal) brightness, and dim the lighting equipment in the fourth section to 30% of the (normal) brightness. The size of each section can be set as needed, but is not limited thereto. And the size of each section can be fixed or changed based on the movement of personnel.

[0056] In at least one embodiment, the first control signal is used to control the driver to dim the lighting equipment based on the movement of the person. If the person is walking, the lighting equipment above the person (in the first part) will be dimmed to the first predetermined level, so the goal of "shifting lights" can be achieved, which means that the light-on area will shift with the movement of the person. And the lighting equipment in other areas (except the first part) is working in energy-saving mode. And a large amount of energy can be saved at a lower cost.

[0057] In at least one embodiment, when the detector 101 detects that the person is not moving (sitting down or standing (staying)), the controller 20 generates a second control signal, which is used to control the driver to keep the lighting equipment above the person turned on. For example, when the detection device (detector 101) detects that the person is not moving, the processor generates a second signal. The communication unit 102 is configured to send the second signal S2 to the controller 20 via wireless communication (such as Bluetooth communication). But not limited to this, for example, the wireless communication can be WIFI communication, etc. When the detection device (detector 101) detects that the person is not moving, the lighting equipment above the person is kept turned on. For example, the lighting equipment in the first part maintains 100% (normal) brightness, so it can avoid the situation where the person stays in the tunnel but the lights are dimmed.

[0058] In at least one embodiment, when the detection device (detector 101) detects that the number of people in the tunnel is equal to zero, the controller generates a third control signal; the third control signal is used to control the driver to dim the lighting equipment to a second predetermined level. For example, when the detection device (detector 101) detects that the number of people in the tunnel is equal to zero, the processor generates a third signal. The communication unit 102 is configured to send the third signal S3 to the controller 20 via wireless communication (such as Bluetooth communication). But not limited to this, for example, the wireless communication can be WIFI communication, etc. When the detection device (detector 101) detects that the number of people in the tunnel is equal to zero (that is, there are no people in the tunnel), the lighting equipment is dimmed to the second predetermined level. Therefore, a large amount of energy can be saved at a lower cost.

[0059] In at least one embodiment, the third control signal is used to control the driver to dim the lighting equipment in the area other than the entrance area from the second predetermined level to the third predetermined level after a predetermined time has passed. For example, when the detection device (detector 101) detects that the number of people in the tunnel is equal to zero (i.e., no people are in the tunnel), the lighting equipment is dimmed to the second predetermined level (e.g., 30% brightness) every predetermined time (e.g., 30 minutes), and all lighting equipment except the lighting equipment on the entrance area of ​​the tunnel will be reduced by a second amount (e.g., 10%) until it is turned off (0% brightness, or turned off), that is, after a predetermined time (e.g., 30 minutes), all lighting equipment except the lighting equipment on the entrance area of ​​the tunnel will be dimmed from the second predetermined level (e.g., 30% brightness) to the third predetermined level (e.g., 20% brightness), and then after another 30 minutes, all lighting equipment except the lighting equipment on the entrance area of ​​the tunnel will be dimmed from 20% brightness to 10% brightness. Then, all lighting equipment except the lighting equipment on the entrance area of ​​the tunnel will be turned off after another 30 minutes. The lighting equipment on the entrance area of ​​the tunnel may be maintained at a second predetermined level (eg 30% brightness) until the facility is closed.

[0060] In at least one embodiment, when the facility is closed, the system switches to "patrol mode". This mode will turn on the lighting equipment in the area when any sensor in the area detects movement. No movement of personnel within a second predetermined time (e.g., 30 minutes) will automatically turn off all lighting equipment. For example, patrol mode will be turned on between 00:30 and 05:30.

[0061] In at least one embodiment, when the detection device (detector 101) detects that the number of people in the tunnel (changes to) is greater than the first threshold and detects the movement of people on both sides of the entrance area of ​​the tunnel, the controller 20 generates a fourth control signal; the fourth control signal is used to control the driver to keep the lighting equipment always turned on. For example, the detection device may also include one or more sensors. The sensor may be a PIR sensor deployed on both sides of the entrance area of ​​the tunnel. The sensor can sort out the trend of people entering the tunnel. When the detector 101 detects that the number of people in the tunnel changes to be greater than the first threshold and the sensors around the two sides of the entrance area of ​​the tunnel detect movement (there are people entering the tunnel), the sensor generates a fourth signal-1 and sends the fourth signal-1 to the controller 20 via wireless communication (such as Bluetooth communication). The processor generates a fourth signal-2. The communication unit 102 is configured to send the fourth signal-2 to the controller 20 via wireless communication (such as Bluetooth communication). But not limited to this, for example, the wireless communication may be WIFI communication, etc. When the detection device 10 detects that the number of people is greater than the first threshold and detects the movement of people on both sides of the entrance area of ​​the tunnel, the "tunnel mode" is turned off to keep the lighting equipment in the entire tunnel always turned on.

[0062] Figure 3 is a diagram of a system for controlling lighting equipment according to an embodiment of the present disclosure. Figure 3 As shown, the controller 20 can be regarded as a cloud processor. The controller 20 is connected to the detection device (detector 101 or sensor 103), the driver 30 and the lighting equipment 40 via wireless communication. The controller 20 sends a first control signal, a second control signal, a third control signal and / or a fourth control signal to the driver via wireless communication (such as Bluetooth communication). The driver can be deployed at the lighting equipment, or can be deployed at the central control room, or can be deployed in the cloud. But not limited to this. The detector (camera) is usually present in the tunnel. Therefore, additional installation is reduced. Use existing equipment with software service support (or sensors with limited increase) to reduce installation. Therefore, a large amount of energy can be saved at a lower cost.

[0063] According to the first aspect of the embodiment, the situation where a person stays in a tunnel but the lights are dimmed can be avoided. And a large amount of energy can be saved at a lower cost. The person and the security personnel have a more comfortable experience and do not feel sacrificed for energy saving. And the security personnel no longer need to use a flashlight when patrolling.
