[0027] Figure 1 This is a circuit diagram of an optional embodiment of the intelligent lighting guidance system for tunnels according to this utility model. Detailed Implementation
[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present utility model and are not intended to limit the present utility model. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.
[0029] like Figure 1 As shown, an optional embodiment of this utility model provides a tunnel intelligent lighting guidance system, comprising:
[0030] A guide light group 1 is formed by sequentially connecting multiple guide lights 10 arranged at predetermined intervals along the direction of the road inside the tunnel.
[0031] One end of the guide light group 1 is connected to the main controller 3, which is used to control the lighting and turning off of each guide light in the guide light group 1;
[0032] The other end of the guide light group 1 is also connected to a backup controller 5. The backup controller 5 is connected to the main controller 3 and is in standby mode when the main controller 3 is working normally. When the main controller 3 fails, it automatically starts to control the lighting of each guide light in the guide light group 1.
[0033] This embodiment of the invention connects a main controller 3 and a backup controller 5 to both ends of the guide light group 10. Under normal conditions, the main controller 3 controls the on / off state of each guide light 10 in the guide light group 1, while the backup controller 5 is in standby state. When the main controller 3 fails, the backup controller 5 can quickly start and take over the work of the main controller 3 to control the on / off state of each guide light 10 in the guide light group 1, which can effectively achieve redundancy backup. Even when a single light controller fails, the normal operation of the guide light 10 can still be guaranteed.
[0034] In an optional embodiment of this invention, the backup controller 5 is connected to the main controller 3 via the guide light group 1, so that it can automatically start if it does not receive a light control signal from the main controller 3 via the guide light group 1, indicating that the main controller 3 has malfunctioned. In this embodiment, the backup controller 5 determines whether the main controller 3 is malfunctioning by judging whether it receives a light control signal from the main controller 3 via the guide light group 1, thus simplifying the wiring connection.
[0035] In an optional embodiment of this utility model, the backup controller 5 is connected to the main controller 3 via a fault detection cable, and the backup controller 5 includes:
[0036] The controller fault detection module 50, connected to the main controller 3 via the fault detection cable, is used to monitor whether the main controller 3 has a fault in real time, and to generate a controller fault command when a fault is detected; and
[0037] The lamp control module 52 is connected to the controller fault detection module 50 and is used to respond to the controller fault command to automatically start and control the lighting and extinguishing of each of the guide lamps 10 in the guide lamp group 1.
[0038] In this embodiment, the backup controller 5 can also be connected to the main controller 3 via a fault detection cable. When the controller fault detection module 50 detects a fault in the main controller 3, it automatically starts the internal light control module 52 to control the operation of each guide light 10 in the guide light group 1.
[0039] In an optional embodiment of this utility model, each of the guide lights 10 in the guide light group 1 is connected sequentially in a breakpoint resume mode. In this embodiment, each of the guide lights 10 in the guide light group 1 can be electrically connected sequentially in a breakpoint resume mode to achieve communication and power transmission. When a guide light 10 in the guide light group 1 fails, the communication signal can automatically bypass the fault point, ensuring the normal and stable operation of other guide lights 10 on the line.
[0040] In an optional embodiment of this utility model, the system further includes an emergency power supply 7 for providing emergency power to the main controller 3 and the backup controller 5, wherein both the main controller 3 and the backup controller 5 include:
[0041] The power management module 54 is connected to the external mains power supply 8 via a power supply line and to the emergency power supply 7, and is used to power the controller and each of the guide lights 10 in the guide light group 1 using the external mains power supply 8 under normal conditions; and
[0042] The power supply fault detection module 55 is connected to the power management module 54 and is used to monitor in real time whether the power supply line between the power management module 54 and the external mains power supply 8 is interrupted. If so, it outputs a power supply fault command to control the power management module 54 to use the emergency power supply 7 to supply power to the controller and each of the guide lights 10 in the guide light group 1.
[0043] In this embodiment, the main controller 3 and the backup controller 5 are also connected to an emergency power supply 7 that provides emergency power. Under normal conditions, the power management module 54 of each controller uses an external mains power supply 8 to power each of the guide lights 10 in the guide light group 1. When a safety accident occurs in the tunnel and the power supply line between the external mains power supply 8 and the power management module 54 is damaged or the mains power fails, the power supply fault detection module 55 can quickly generate a power supply fault command to control the power management module 54 to use the emergency power supply 5 to power each of the guide lights 10 in the guide light group 1, thereby ensuring the emergency operation of the guide light group 1 when there is no mains power.
[0044] In an optional embodiment of this utility model, there are two emergency power supplies 7, with the main controller 3 and the backup controller 5 each connected to one of the emergency power supplies 7. In this embodiment, connecting the main controller 3 and the backup controller 5 to each of the emergency power supplies 7 simplifies the wiring and avoids system paralysis due to a fault when only one emergency power supply 7 is provided.
[0045] In an optional embodiment of this utility model, the tunnel intelligent lighting guidance system further includes a remote lighting control device 9 for generating corresponding lighting display strategies based on real-time road traffic conditions within the tunnel. Both the main controller 3 and the backup controller 5 further include:
[0046] The normal communication module 56 is connected to the remote lighting control device 9 and is used to receive the lighting display strategy issued by the remote lighting control device 9.
[0047] The light control module 52 is also connected to the normal communication module 56 to control the operation of each guide light 10 in the guide light group 1 based on the light display strategy.
[0048] In this embodiment, a remote lighting control device 9 is also provided. This device can accurately obtain the traffic conditions inside the tunnel by interfacing with the traffic road system, thereby generating a reasonable lighting display strategy. Finally, the strategy is sent to the normal communication module 56 of the corresponding controller, and the light control module 52 controls the operation of each guide light 10 in the guide light group 1 based on the lighting display strategy. In specific implementation, the corresponding controller can interfacing with the traffic road system to determine the lighting display strategy itself.
[0049] In an optional embodiment of this utility model, both the main controller 3 and the backup controller 5 further include:
[0050] The communication fault detection module 57, connected to the normal communication module 56, is used to monitor in real time whether the communication between the normal communication module 56 and the remote lighting control device 9 is interrupted; if so, it generates and outputs a communication fault command.
[0051] The emergency communication module 58 is connected to the communication fault detection module 57 and the light control module 52 respectively, and is used to respond to the communication fault command to receive the light display strategy by communicating with the remote lighting control device 9 in an emergency.
[0052] In this embodiment, when a safety accident occurs in the tunnel, disrupting the communication between the remote lighting control device 9 and the normal communication module 56, the communication fault detection module 57 can quickly detect and generate a corresponding communication fault command. This, in turn, controls the wireless communication module 58 to communicate wirelessly with the remote lighting control device 7 to receive the lighting display strategy, ensuring normal data communication. Specifically, the normal communication module 56 typically uses wired communication to communicate with the remote lighting control device 9, while the emergency communication module 58 typically uses wireless communication to communicate with the remote lighting control device 9.
[0053] In an optional embodiment of this invention, the normal communication module 58 and the emergency communication module 56 are respectively connected to the controller fault detection module 50 to upload the controller fault command to the remote lighting control device 9. In this embodiment, the lamp group fault information can also be uploaded to the remote lighting control device 7 via the normal communication module 58 or the emergency communication module 56, facilitating maintenance personnel to be aware of lamp group circuit faults and fault locations, and simplifying repairs.
[0054] In an optional embodiment of this invention, the main controller 3 and the backup controller 5 have the same structure. In this embodiment, when the main controller 3 and the backup controller 5 have the same structure, they can serve as backups for each other, and when one fails, the other can completely replace it.
[0055] Specifically, multiple guide light groups 1 are installed along the road extension direction within the tunnel. Since different sections of the road within the tunnel may have different traffic conditions, requiring different lighting guidance methods, multiple guide light groups 1 are installed along the road extension direction within the tunnel. Each guide light group 1 can be configured with different lighting display strategies according to the actual conditions of the corresponding road section. In specific implementation, within a guide light group 1, typically one guide light 10 is installed every 5-10 meters. Figure 1 In this embodiment, only 5 guide lights 10 are schematically drawn.
[0056] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
