[0002] The intelligent lighting control method is to deploy a tunnel lighting and disaster prevention remote monitoring system based on intelligent detection devices in the tunnel. When a train is detected to slow down or stop in the tunnel due to a malfunction or emergency accident, the tunnel lighting and disaster prevention remote monitoring system will automatically control the opening of the tunnel emergency lighting.

[0003] When an emergency occurs in a tunnel, photoelectric, acoustic, and laser detection sensors are usually used to obtain train status information in the railway tunnel. However, photoelectric and laser detection devices rely on the emission and reception of light. Tunnels are dusty outdoor environments. In addition, the dust raised by high-speed trains that pass through every day will gradually accumulate on the emission and receiving windows of the photoelectric or laser detection devices over time, thereby affecting the emission and reception of light. If they are not cleaned regularly, they will eventually lose their detection capabilities.

[0004] Therefore, how to accurately and real-time obtain the driving status of railway tunnel trains and reduce missed reports and false reports is a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0033] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the operations (or steps) as sequential processes, many of the operations (or steps) therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0034] Long-distance railway tunnels must provide tunnel lighting, fans and other disaster prevention and rescue evacuation systems, as well as tunnel lighting and disaster prevention remote monitoring systems (Building Automation System, tunnel BAS system), which mainly include monitoring of tunnel lighting and tunnel fans. Tunnel BAS system generally includes local and remote monitoring. Local control is achieved through the entrance and exit dual control unit box installed at the tunnel entrance with the function of turning on or off the tunnel lighting with one button, and the manual control unit box (or manual button box, or emergency start box) with one-button tunnel lighting turned on and off arranged at a certain distance on both sides of the tunnel; remote control is to use the tunnel BAS monitoring terminal located in the railway bureau monitoring center or station control room to connect the local tunnel lighting control system through the railway dedicated communication network to realize the remote opening and closing of the tunnel lighting.

[0035] The current tunnel BAS system, whether it is local control or remote control, is a manual control method. When a train stops unexpectedly in the tunnel due to a fault or fire, the tunnel lighting system is turned on locally or remotely to help the people on the train evacuate and assist in rescue work. The manual control method will inevitably be affected by the staff's proficiency in operating the tunnel BAS equipment and the concentration of the on-duty personnel at work. Generally speaking, a person's concentration has a certain time limit. It is difficult to maintain continuous attention to a single job day after day and every moment, and it is difficult to ensure that they will not leave their posts. When an emergency occurs in the tunnel, if the tunnel evacuation lighting and the start-up of the rescue fan cannot be operated in time, it will inevitably affect the timeliness of the overall evacuation and rescue, especially the lighting system in the tunnel. If it cannot be turned on in time, the long tunnel will be as dark as the dark night, which will seriously affect the rescue and evacuation work, resulting in irreparable loss of life and property.

[0036] In the prior art, photoelectric, acoustic and laser detection sensors are usually used to implement the detection. The train status information generated by the detection is transmitted to the tunnel main central control module of the tunnel BAS system, and the tunnel main central control module automatically controls the tunnel lighting. However, the above detection methods all have their own disadvantages. Both photoelectric and laser detection devices rely on the emission and reception of light. Tunnels are dusty outdoor environments. In addition, the dust raised by high-speed trains that shuttle through every day will gradually accumulate dust on the emission and receiving windows of photoelectric or laser detection devices over time, thereby affecting the emission and reception of light. If they are not cleaned regularly, they will eventually lose their detection capabilities.

[0037] Therefore, the embodiment of the present invention provides a radar-based railway tunnel lighting intelligent control system and method, which monitors the braking, slowing down and stopping of trains in tunnels due to faults or accidents, and the tunnel BAS system automatically controls the turning on of tunnel emergency lighting to promptly assist tunnel emergency rescue and evacuation work and reduce accident losses.

[0038] Embodiment 1

[0039] Figure 1A is a schematic diagram of the structure of a radar-based railway tunnel lighting intelligent control system provided by the first embodiment of the present invention. This embodiment is applicable to the case of automatic control of railway tunnel lighting, such as Figure 1A As shown, the radar-based railway tunnel lighting intelligent control system provided in the embodiment of the present invention may include: a radar detector 110, a train stop monitoring module 120, a tunnel slave central control module 130 and a tunnel master central control module 140; wherein:

[0040] The radar detector 110 is configured to obtain the train speed in the railway tunnel and send the train speed to the train stop monitoring module.

[0041] The radar detector obtains the moving speed and moving direction of the object under test based on the calculation of the received reflected wave frequency shift. In the embodiment of the present invention, a radar detector is used to obtain train travel information such as the speed and direction of the train in the railway tunnel, and the train travel information is sent to the train stop monitoring module.

[0042] Figure 1B This is a schematic diagram of the installation and detection direction structure of a radar detector provided by an embodiment of the present invention, see Figure 1B The radar detector is installed at a height of about 2.5m from the tunnel cable trough cover. The plane of the radar detector is perpendicular to the ground and points to the centerline of the tunnel. Pointing the detection direction of the radar detector to the centerline of the railway tunnel can obtain the train speed and direction in a larger range.

[0043] The train stop monitoring module 120 is configured to send train slow-moving information to the tunnel central control module if the train speed is less than the low-speed driving threshold; wherein the train slow-moving information includes the train speed, the train direction and the local address code of the train stop monitoring module.

[0044] Among them, the train stop monitoring module may refer to receiving the train speed and determining whether the train speed is less than the low-speed driving threshold. When the train speed is less than the low-speed driving threshold, it is determined that the train in the railway tunnel is in a slow-moving state, and the train slow-moving information including the local address code of the train stop monitoring module is sent to the tunnel central control module. The address codes of the train stop monitoring modules in a tunnel are set in the order of their locations. A train stop monitoring module address code represents a specific tunnel location, so that the host computer located in the monitoring center can determine the parking position of the train according to the address code of the alarm train stop monitoring module, thereby facilitating rescue command.

[0045] Figure 1C This is a schematic diagram of the layout spacing and detection range structure of a train stop monitoring module provided by an embodiment of the present invention, see Figure 1C The train stop monitoring module is arranged in the tunnel. The train stop monitoring module is arranged in the tunnel at a fixed interval, which can be 25m, 50m and 100m, etc. The arrangement density depends on the detection distance of the radar detector. The train stop monitoring module is installed on the tunnel wall of the tunnel main line. The train stop monitoring module is connected to the tunnel slave central control module through a dedicated control bus laid on the tunnel wall, communicates with the tunnel slave central control module and is powered by the tunnel slave central control module.

[0046] Among them, the dedicated control bus can be a two-core bus using a two-core cable that integrates communication and power supply, which is commonly used in fire alarm systems or remote meter reading systems, or it can be an AC power line carrier line or a DC power line carrier line that can provide AC or DC power supply to multiple master and slave devices on a pair of cables and provide carrier communication functions at the same time, which will not be repeated later.

[0047] Among them, low-speed driving can refer to a slow speed lower than the normal speed of tunnel trains. When the train is in this speed range, it is defined as low-speed driving. The low-speed driving threshold can be set, ranging from 50-120km / h, and the default value can be 100km / h. When the radar detector detects that the train is traveling at a low speed in the tunnel, the system will regard the train as an object of attention and upload the train slowing information to the tunnel central control module. The low-speed driving threshold can filter out the vast majority of trains with a driving speed greater than the low-speed driving threshold, and the system does not need to process it.

[0048] The tunnel slave central control module 130 is configured to receive the train slow-moving information and forward the train slow-moving information to the tunnel master central control module.

[0049] Among them, the tunnel slave central control module may refer to receiving the train deceleration information, and sending the train deceleration information including the local address code of the tunnel slave central control module to the tunnel master central control module.

[0050] A tunnel slave central control module is set in the railway tunnel. Taking the power supply arm in the tunnel as a unit, each power supply arm is provided with a tunnel slave central control module. The tunnel slave central control module is installed in the power cavern in the tunnel. One side of the tunnel slave central control module is connected to the train stop monitoring module through a dedicated control bus, and the train travel information monitored by the train stop monitoring module is collected at any time. The other side of the tunnel slave central control module is connected to the lighting distribution and control box that provides power and on-off control for the tunnel lighting of the power supply arm through a real loop line, so as to realize the start and stop control of the lighting fixtures of the power supply arm; long and large tunnels generally have multiple power supply arms, each power supply arm is provided with a tunnel slave central control module, and multiple tunnel slave central control modules are interconnected and communicated through optical fibers; each tunnel is also provided with a tunnel master central control module, which is interconnected with each tunnel slave central control module through an optical fiber ring network, and the tunnel master central control module is responsible for completing the overall coordination of the lighting control in the entire tunnel. Among them, the power supply arm is a preset power supply range for the lighting fixtures in the tunnel that is responsible for powering the lighting fixtures in the tunnel by a single set of tunnel lighting power supply, for example, a single set of tunnel lighting power supply is responsible for powering the equipment within a range of 2-3km in the tunnel.

[0051] The tunnel main central control module 140 is configured to determine that a train failure occurs in the railway tunnel and control the lighting in the railway tunnel to turn on if the train travel speed is less than the slow travel threshold.

[0052] The tunnel master central control module may receive the train slow-moving information and determine whether the train speed is less than the slow-moving threshold. If the train speed is less than the slow-moving threshold, the tunnel master central control module determines that the train has a fault and sends a lighting start instruction to each tunnel slave central control module in the tunnel. The tunnel master central control module uses a comparison between the train speed and the speed threshold combined with an intelligent algorithm to control the start of tunnel lighting.

[0053] Wherein, slow travel may refer to a train traveling in a tunnel at a speed not higher than a slow travel threshold; the slow travel threshold may be set in a range of 0-60km / h, and a default value may be 30km / h. When the radar-based railway tunnel lighting intelligent control system detects that a train is traveling slowly in a tunnel, it is determined that the train is in an accident state, and the tunnel lighting will be directly controlled to be turned on.

[0054] In an optional scheme of an embodiment of the present invention, the system also includes: synchronous control of the rescue channel protection door used for tunnel evacuation, that is, while controlling the lighting to turn on, the rescue channel protection door is opened to provide a smooth evacuation channel for the crowd to be evacuated and rescued after the train stops, thereby improving the evacuation efficiency and reducing the damage caused by the accident.

[0055] In an optional scheme of an embodiment of the present invention, the system also includes: synchronous control of the fan equipment used for tunnel evacuation and rescue, that is, while controlling the lighting to turn on, turning on the tunnel fan to provide a ventilation environment for the people evacuated and rescued after the train stops. This is particularly important when an accident train has a fire risk and stops for evacuation, which can reduce casualties caused by harmful gases such as smoke and carbon monoxide.

[0056] An embodiment of the present invention provides a radar-based railway tunnel lighting intelligent control system, the system comprising: a radar detector, a train stop monitoring module, a tunnel slave central control module and a tunnel master central control module; wherein: the radar detector is configured to obtain the train speed in the railway tunnel and send the train speed to the train stop monitoring module; the train stop monitoring module is configured to send the train slow-moving information to the tunnel slave central control module if the train speed is less than a low-speed driving threshold; wherein the train slow-moving information includes the train speed, the train direction and the local address code of the train stop monitoring module; the tunnel slave central control module is configured to receive the train slow-moving information and forward the train slow-moving information to the tunnel master central control module; the tunnel master central control module is configured to determine that a train failure occurs in the railway tunnel and control the lighting in the railway tunnel to turn on if the train speed is less than the slow-speed driving threshold. By adopting the technical solution of the embodiment of the present invention, radar detectors are arranged at the tunnel entrance and in the tunnel. When it is determined that the train is not traveling normally in the tunnel, the tunnel lighting equipment is automatically turned on. This can not only improve the timeliness of the lighting and fans required for evacuation and rescue in the tunnel after the train stops in an emergency due to fire or other accidents, but also avoid or reduce personal and property losses caused by delayed evacuation and rescue due to untimely manual control.

[0058] Figure 2A 1 is a schematic diagram of a radar-based railway tunnel lighting intelligent control system provided by the second embodiment of the present invention. The embodiment of the present invention further optimizes the above embodiment on the basis of the above embodiment. The embodiment of the present invention can be combined with various optional solutions in one or more of the above embodiments. Figure 2A As shown, the radar-based railway tunnel lighting intelligent control system provided in the embodiment of the present invention may include: a radar detector, a train stop monitoring module, a tunnel slave central control module and a tunnel master central control module; wherein:

[0059] Train stop monitoring module (i.e. Figure 2A The TSU in the tunnel is connected to the central control module (i.e. Figure 2A The TCU (slave) in the power cavern is connected to a dedicated control bus extending in the up and down directions of the power cavern, communicating with the tunnel slave central control module, which is responsible for power supply. The train departure monitoring modules are arranged at equal intervals, and the spacing refers to the detection range of the radar detector. If the detection range of the radar detector is 200 meters, the spacing can be 200 meters.

[0062] Among them, the radar detector installed in the railway tunnel is used to monitor the speed and direction of the train in the railway tunnel, and the radar detector installed at the entrance of the railway tunnel is used to monitor whether the train has left the tunnel. When the train in the railway tunnel resumes running and leaves the tunnel, the radar detector installed at the entrance of the railway tunnel monitors the speed and direction of the train, and sends the speed and direction of the train to the train stop monitoring module.

[0063] Based on the above embodiment, optionally, the train stop monitoring module includes:

[0066] Among them, a radar detector for monitoring the speed and direction of the train is installed at a preset distance above the train stop monitoring module and is connected through a solid loop line.

[0067] The radar-based railway tunnel lighting intelligent control system will pre-set two speed thresholds, and divide the trains that are detected to be slowing down for the first time in the tunnel into two categories, and give different corresponding processing methods. The train stop monitoring module will only upload the travel information of trains in slow and low-speed driving states to the central control module of the tunnel where they are located.

[0068] in, Figure 2B FIG. 1 is a flow chart of a train stop monitoring module for determining a train speed according to an embodiment of the present invention. Figure 2B, the train stop monitoring module receives the train speed, each train stop monitoring continuously monitors the train speed, and determines whether the train speed is less than the low-speed driving threshold. If the train speed is less than the low-speed driving threshold, it is determined that the train is in a slow-moving state and the train slow-moving information is sent to the tunnel slave central control module. When the train speed is less than the low-speed driving threshold, a train slow-moving information with a local encoding address is sent to the tunnel slave central control module of the power supply arm through a dedicated control bus. The low-speed driving threshold can be set in the range of 50-120km / h, and the default value is temporarily set to 100km / h. Different railway lines have different speed limits. This parameter can be set according to the specific railway speed limit value, and is not specifically limited in the embodiment of the present invention. Among them, the power supply arm may refer to the power supply arm to which the train stop monitoring module belongs. All train stop monitoring modules belonging to the power supply arm are connected through 2*2.5mm 2 A dedicated control bus connects the power supply arm to the tunnel chamber from the central control module.

[0069] Based on the above embodiment, optionally, the tunnel slave central control module includes:

[0071] in, Figure 2C This is a schematic diagram of a process of forwarding information from a central control module to a tunnel provided in an embodiment of the present invention. Figure 2C The tunnels to which the railway tunnel belongs are interconnected from the central control module through an optical fiber loop, and the central control module of each tunnel is connected to the tunnel master central control module (i.e. Figure 2A After the tunnel receives the train slow-moving information from the central control module, it adds the address code of the central control module of the tunnel and sends it to the tunnel master central control module of the railway tunnel.

[0072] Based on the above embodiment, optionally, the tunnel main central control module includes:

[0073] Receiving the train slow-moving information and determining whether the train speed is less than a slow-moving threshold;

[0074] If the train speed is less than the slow travel threshold and the railway tunnel is not currently in an open state, sending a tunnel lighting opening instruction to a tunnel slave central control module in the railway tunnel;

[0075] Set the tunnel lighting on status bit and the train travel direction status bit and send the train slowing information and tunnel lighting on information to the host computer;

[0076] Wherein, the tunnel master central control module is connected to at least one tunnel slave central control module.

[0077] in, Figure 2D This is a schematic diagram of a process of intelligently controlling tunnel lighting by a tunnel master central control module provided in an embodiment of the present invention, see Figure 2D The tunnel master central control module receives and records the train slow-moving information, and determines whether to automatically turn on the tunnel lighting according to the train speed and the tunnel lighting on status bit; when it is confirmed that the train is below the slow-moving threshold and the tunnel lighting is not currently on (i.e., the train speed is less than the slow-moving threshold and the tunnel lighting on status bit is 0), it sends a tunnel lighting on command to all tunnel slave central control modules in the tunnel, and each tunnel slave central control module sends a light-on signal to the tunnel lighting power distribution and control box associated with it through the output unit of the local unit to turn on the tunnel lighting of each power supply arm. The tunnel master central control module simultaneously sets the tunnel lighting on status bit and the train driving direction status bit and sends the train slow-moving information and tunnel lighting on information to the host computer.

[0078] Based on the above embodiment, optionally, the tunnel slave central control module further includes:

[0079] Receive the tunnel lighting start instruction sent by the tunnel master central control module, and send a lighting start signal to the tunnel lighting power distribution and control box associated with the tunnel slave central control module to turn on the lighting.

[0080] Each tunnel receives a lighting start command from the tunnel master central control module, and is responsible for linking the associated tunnel lighting power distribution and control box to turn on the tunnel lighting.

[0081] Based on the above embodiment, optionally, the system further includes:

[0082] The upper computer is configured to receive the train slow-moving information and tunnel lighting on information and issue a pop-up alarm; a train slow-moving icon is displayed on the monitoring interface to facilitate on-duty personnel to intuitively find problem trains in the tunnel.

[0083] in, Figure 2E is a flow chart of a host computer train slow running and tunnel lighting monitoring program provided in an embodiment of the present invention, see Figure 2E , the host computer receives the train slowing information and the tunnel lighting on information; the host computer pops up an alarm, prompting "train slowing, tunnel lighting on", and displays a train slowing icon on the monitoring interface.

[0084] In an optional scheme of an embodiment of the present invention, if the host computer only receives the "train slowing down" information but not the "tunnel lighting on" information, a "train slowing down" icon is displayed in a graphical manner in the "xx area" of "in the xx tunnel".

[0085] In another optional scheme of the embodiment of the present invention, if the "train slows down" information is received together with the "tunnel lighting is on" information, a pop-up alarm prompts "the train slows down in the railway tunnel and the tunnel lighting is on"; and a graphical display of "in the xx area of ​​the xx tunnel" with "train slows down" is displayed; the graphical display information includes but is not limited to position, speed and direction information.

[0086] The embodiment of the present invention provides a radar-based railway tunnel lighting intelligent control system. The tunnel intelligent lighting control system based on the radar detector detects the trains entering the tunnel, pays no attention to the trains running normally, and pays attention to the trains running at low speed, slow speed or stopped in the tunnel. The train stop monitoring module determines the running speed of the train, and transmits the generated digital signal to the tunnel slave central control module in the tunnel using a dedicated communication line. The tunnel slave central control module sends the train slow-moving information with the local address code attached to the tunnel master central control module. The tunnel master central control module determines the slow-moving and stopped status of the train according to the preset slow-moving threshold, and then automatically turns on the tunnel lighting by controlling the tunnel slave central control module in the tunnel, so as to facilitate the emergency evacuation and subsequent rescue of the personnel on the train. At the same time, the radar-based railway tunnel lighting intelligent control system can be used to synchronously control the fan equipment used for tunnel evacuation and rescue. That is, while controlling the lighting to turn on, the tunnel fan can be turned on to provide a ventilation environment for the people who are evacuated and rescued after the train stops. This is especially important when an accident train is in danger of fire and stops for evacuation, which can reduce casualties caused by harmful gases such as smoke and carbon monoxide.

[0093] In an optional scheme of an embodiment of the present invention, if the train speed is less than the slow driving threshold, the tunnel lighting on status bit is 1, the train exits the tunnel entrance and the train driving direction is consistent, it is judged that the train exits the tunnel, and the tunnel main central control module sends a tunnel lighting off instruction; wherein, in the embodiment of the present invention, the tunnel lighting on status bit is 1, indicating that the tunnel lighting on status bit is on; the value of the tunnel lighting on status bit is not specifically limited in the embodiment of the present invention.

[0094] In another optional scheme of the embodiment of the present invention, if the train speed is greater than the slow driving threshold, the tunnel lighting on state bit is 1 and the train driving direction is consistent, it is judged that the train resumes driving, and the tunnel main central control module sends a tunnel lighting off command.

[0095] in, Figure 3B FIG. 1 is a flow chart of a train departure monitoring module determining a train speed according to a third embodiment of the present invention. Figure 3B When a train starts to move from its original parking state in a tunnel or gradually leaves the tunnel, the train departure monitoring module will detect that the train speed has recovered to above the slow speed threshold and less than the low speed threshold, or the train departure monitoring module at the tunnel entrance detects that the train has left the tunnel. The above train departure monitoring module will collect the train slow movement information (for example, speed, direction and position information) and report it to the tunnel central control module. Figure 3C This is a schematic diagram of a process of forwarding information from a central control module to a tunnel provided by Embodiment 3 of the present invention. Figure 3C After receiving the train slow-moving information from the central control module, the tunnel adds the local address code of the tunnel slave central control module and sends it to the tunnel master central control module of the railway tunnel. Figure 3DThis is a schematic diagram of a process of intelligently controlling tunnel closing by a tunnel master central control module according to Embodiment 3 of the present invention, see Figure 3D , the tunnel master central control module determines whether the train that caused the tunnel lighting to be automatically turned on has restored its speed to above the slow threshold or the train has left the tunnel according to the train slowing information combined with the tunnel lighting on status bit and the train driving direction status bit; if the train speed is lower than the slow driving threshold, the tunnel lighting on status bit is 1, the train has left the tunnel entrance and the train driving direction is consistent, the tunnel master central control module determines that the train has left the tunnel entrance; or if the train speed is higher than the slow driving threshold, the tunnel lighting on status bit is 1 and the train driving direction is consistent, the tunnel master central control module determines that the train has restored its speed from the parking or slow driving state to above the slow threshold. The tunnel master central control module sends a tunnel light off instruction to all tunnel slave central control modules in the tunnel; each tunnel slave central control module sends a light off signal to the corresponding tunnel lighting power distribution and control box to execute the light off operation; at the same time, the tunnel lighting on status bit and the train driving direction status bit are cleared and the train slowing information and tunnel lighting off information are sent to the host computer. Figure 3E This is a flow chart of a host computer train slow running and tunnel lighting monitoring program provided in the third embodiment of the present invention, see Figure 3E The host computer receives the train slow-moving information and the tunnel lighting off information, and makes corresponding adjustments to the train slow-moving prompt screen displayed on the monitoring interface, canceling the pop-up prompt of "train slow-moving, tunnel lighting on".

[0096] In an optional solution of the embodiment of the present invention, the system further includes:

[0097] The host computer is configured to receive the tunnel lighting shutdown instruction, cancel the pop-up warning prompt and update the train slow-moving icon in the tunnel.

[0098] Among them, when the tunnel main central control module receives the train slowing down information in the tunnel, it will be transmitted to the host computer of the monitoring center. The host computer will display it in a graphical way according to the information of the train resuming running, reminding the center's on-duty personnel to pay attention; when the host computer receives the information that the tunnel lighting is automatically turned off, while graphically displaying the train's running status, it will also cancel the pop-up prompt of the alarm information "Train slowing down in the tunnel; tunnel lighting is on" and update the train slowing down icon in the tunnel.

[0099] In an embodiment of the present invention, a radar-based railway tunnel lighting intelligent control system is provided. When the radar detector detects that the train has resumed its running speed from a stopped or slow-running state to above a slow-running threshold or is gradually leaving the tunnel, a train slow-running message is uploaded through a train departure monitoring module. The tunnel main central control module can determine that the train has resumed running or left the tunnel area according to an intelligent algorithm for train departure and issue a light-off command, thereby realizing an automatic light-off function after the train leaves and minimizing unnecessary energy loss.
