Description

Technical Field

[0001] The utility model relates to the field of underground passage safety, in particular to a safety induction light source opening and closing system for underground passages. Background Art

[0002] Underground passages (especially underground garage entrances and exits) are generally dimly lit, and most of them have blind spots such as bends and / or turns and / or uphill and downhill slopes and / or T-shaped roads and / or Y-shaped roads and / or cross-shaped roads and / or star-shaped roads, which cause great inconvenience to drivers entering and exiting underground garages.

[0003] This inconvenience is exacerbated in two-way underground passages. Due to dim lighting and limited visibility in blind spots, drivers and pedestrians are unaware of pedestrians or vehicles in the opposite lane, often traveling at slower speeds. This results in longer entry and exit times, and can easily lead to collisions, scrapes, and scuffing.

[0004] To solve this problem, the applicant of this patent previously applied for application number 202422550987.6, and the patent name is "Underground Garage Entrance and Exit Passageway Safety Guidance System". This patent is applied to the blind section of the underground passage. When the displacement sensor of only one entrance and exit detects that a moving target enters the blind section, the indicator lights of all entrances and exits are controlled to turn on green or flash green. When the displacement sensors of at least two entrances and exits detect that a moving target enters the blind section, the indicator lights of the at least two entrances and exits are controlled to turn on red or flash red, and the indicator lights of the entrances and exits where no displacement sensor detects that a moving target enters the blind section are controlled to turn on green or flash green. The solution in this patent can play a role in safety guidance.

[0005] However, in the solution of this patent, as long as a moving target enters the blind spot section, all indicator lights will work, resulting in a relatively long usage time and frequency of each indicator light, resulting in high energy consumption and affecting the service life.

[0006] Therefore, it is necessary to design a system that can not only play a role in guiding the safety of underground passages but also save energy. Summary of the Invention

[0007] The technical problem to be solved by the utility model is to overcome the defects of the existing technology and provide a safety induction light source starting and closing system for underground passages. It prompts the situation of the opposite lane in the blind area of ​​the underground passage by turning on and off the indicator light, which can not only guide drivers and pedestrians to pass through the underground passage safely, but also is relatively energy-efficient.

[0008] In order to solve the above technical problems, the technical solution of the utility model is: a safety induction light source opening and closing system for an underground passage, comprising a controller, a displacement sensor and an indicator light, wherein the underground passage has a blind section, the blind section has at least two entrances and exits, and each entrance and exit is equipped with the displacement sensor and the indicator light; wherein,

[0009] The displacement sensor is used to detect whether a moving target enters the blind spot section from the entrance or exit where the displacement sensor is located;

[0010] The controller is connected to all displacement sensors and all indicator lights respectively, and is used to control the indicator lights at the entrance and exit of the blind section where the displacement sensor detects that a moving target enters the blind section; and to control the indicator lights at the entrance and exit of the blind section where no displacement sensor detects that a moving target enters the blind section to be turned off.

[0011] Furthermore, the indicator light is constantly on or flashes when in operation.

[0012] Furthermore, the indicator light may be red or yellow when it is on for a long time during operation;

[0013] When the indicator light flashes during operation, it flashes red, or flashes yellow, or flashes red and blue alternately.

[0014] Furthermore, each entrance and exit is provided with at least two indicator lights at intervals along the direction in which the moving object enters the blind spot section.

[0015] In order to further improve the prompt effect, the number of displacement sensors and indicator lights configured at each entrance and exit is equal, each displacement sensor corresponds to an indicator light, and the displacement sensor is installed near or on the corresponding indicator light.

[0016] A specific type of displacement sensor is further provided, wherein the displacement sensor is a microwave radar sensor, an infrared sensor, an infrared laser sensor, or a magnetic induction sensor.

[0017] A first specific type of blind spot section is further provided, wherein the blind spot section is a curve having two entrances and exits.

[0018] A third specific type of blind spot section is further provided, wherein the blind spot section is a multi-intersection special-shaped road, such as a Y-shape, a star-shape, a T-shape, a cross-shape, etc.

[0019] A fourth specific type of blind spot section is further provided, wherein the blind spot section is an uphill and downhill road with two entrances and exits.

[0020] In order to further ensure that the indicator light can also play an indication role when there are pedestrians or vehicles stationary in the blind corner, the underground garage access channel safety guidance system also includes a stationary target detection sensor, which is connected to the controller and is used to detect whether there are pedestrians or vehicles stationary in the blind corner of the blind section; wherein,

[0021] The controller is also connected to the stationary object detection sensor, and is also used to control the operation of the indicator lights of the corresponding entrances and exits when the stationary object detection sensor detects that a pedestrian or vehicle is parked in the blind corner of the blind spot section.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects:

[0023] 1. The present invention uses indicator lights to indicate that a moving target has entered the blind section from the entrance and exit where it is located. If all indicator lights at a certain entrance and exit are not working, it means that no moving target has entered the blind section from that entrance and exit. That is, the present invention can easily prompt whether a moving target has entered each entrance and exit of the blind section, making it convenient for pedestrians and vehicle drivers to understand the situation of the opposite lane and know whether there is a moving target in the opposite lane, thereby reducing the tension and anxiety caused by obstructed vision and poor lighting for pedestrians and vehicle drivers; if there is a moving target in the opposite lane, pedestrians and vehicle drivers will be able to move forward slowly, properly and safely because they know it in advance, thus avoiding accidents. Therefore, the present invention can well serve as a prompt and induction for vehicles and pedestrians entering the blind section of the underground passage, and assist pedestrians and vehicles to safely pass through the underground vehicle passage, especially the blind section of the entrance and exit passage of the underground garage;

[0024] 2. The utility model prompts the situation of the opposite lane in the blind spot section of the underground passage by turning on and off the indicator lights. The working time of each indicator light is relatively short and the frequency of use is relatively low, which is more energy-saving and can greatly extend the service life of the equipment.

[0042] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0043] like Figures 1 to 4 As shown, a safety induction light source opening and closing system for an underground passage includes a controller 1, a displacement sensor 2 and an indicator light 3. The underground passage has a blind section 4, and the blind section 4 has at least two entrances and exits 6. Each entrance and exit 6 is equipped with a displacement sensor 2 and an indicator light 3.

[0044] The displacement sensor 2 is used to detect whether a moving target 5 enters the blind road section 4 from the entrance or exit 6 where it is located;

[0045] The controller 1 is connected to all displacement sensors 2 and all indicator lights 3 respectively, and is used to control the indicator lights 3 to work when the displacement sensor 2 detects that the moving target 5 enters the entrance and exit 6 of the blind spot section 4; and to control the indicator lights 3 to turn off when no displacement sensor 2 detects that the moving target 5 enters the entrance and exit 6 of the blind spot section 4.

[0046] Specifically, this embodiment uses indicator lights 3 to indicate when a moving object 5 enters the blind spot section 4 from its entrance or exit 6. If all indicator lights 3 at a particular entrance or exit 6 are inoperative, this indicates that no moving object 5 has entered the blind spot section 4 from that entrance or exit 6. In other words, this embodiment conveniently indicates whether a moving object 5 has entered each entrance or exit 6 of the blind spot section 4, making it easier for pedestrians and drivers to understand the situation in the oncoming lane and whether there is a moving object 5 in the oncoming lane. This reduces the anxiety and anxiety that pedestrians and drivers experience due to obstructed vision and poor lighting. If there is a moving object 5 in the oncoming lane, pedestrians and drivers will be aware of it in advance, allowing them to proceed slowly, properly, and safely, thus avoiding accidents. Therefore, this embodiment can well serve as a reminder and guidance for vehicles and pedestrians entering the blind section 4 of the underground passage, and assist pedestrians and vehicles to safely pass through the underground vehicle passage, especially the blind section 4 of the underground garage entrance and exit passage; in addition, this embodiment prompts the situation of the opposite lane of the blind section 4 of the underground passage by turning on and off the indicator light 3. The working time of each indicator light 3 is relatively short, the frequency of use is also relatively low, it is more energy-saving, and can extend the service life.

[0047] The indicator light 3 may be on or flashing when in operation. When the indicator light 3 is on, it may be, but not limited to, red or yellow. When the indicator light 3 flashes, it may be, but not limited to, red, yellow, or red and blue alternately.

[0048] The moving target 5 can be a moving vehicle, a pedestrian, or even an animal such as a cat or dog. The controller 1 can be wirelessly connected to all displacement sensors 2 and all indicator lights 3 via a mesh network. The controller can be an MCU, such as an STM32F103RCT6, or an FPGA. When the indicator lights 3 flash during operation, they can also be controlled to flash at different frequencies based on the distance or speed of the moving target 5.

[0049] In one embodiment, each entrance / exit 6 is provided with at least two indicator lights 3 spaced along the direction in which the moving object 5 enters the blind spot section 4. The number of indicator lights 3 can be determined based on the length of the entrance / exit 6 and can be arranged at equal or unequal intervals. It is preferred that the indication information of at least one indicator light at each entrance / exit 6 be visible to pedestrians or vehicles entering the blind spot section 4. If the blind spot section 4 is long, additional corresponding slave devices may be configured.

[0050] In one embodiment, Figures 1 to 4 As shown, the number of displacement sensors 2 and indicator lights 3 configured for each entrance and exit 6 is equal, each displacement sensor 2 corresponds to an indicator light 3, and the displacement sensor 2 is installed near or on the corresponding indicator light 3.

[0051] Preferably, the displacement sensor 2 is installed within the corresponding indicator light 3. This simplifies on-site installation of the entire system in the blind spot 4. Furthermore, the displacement sensor 2 and the indicator light 3 can share a common power supply. To further simplify installation and commissioning of the indicator light 3, a marking can be placed on the outer surface of the indicator light 3. When installing the indicator light 3, aligning the marking with the entrance / exit 6 allows the displacement sensor 2 to accurately and effectively perform its function.

[0052] Of course, the number of displacement sensors 2 and indicator lights 3 at each entrance and exit 6 can be different. The number of displacement sensors 2 and indicator lights 3 can be appropriately set based on the specific direction, detection difficulty, and length of the entrance and exit 6. In this case, the displacement sensors 2 can be installed with the indicator lights 3 or installed independently of the indicator lights 3 at the entrance and exit 6. If the former is the case, two types of indicator lights 3 are required: one with a displacement sensor 2 and the other without.

[0053] In one embodiment, the displacement sensor 2 is a microwave radar sensor, an infrared sensor, an infrared laser sensor, or a magnetic induction sensor. The microwave radar sensor is conventional in the art and will not be described in detail here. It may be model RKB1125B5. Of course, the displacement sensor 2 may also be other types, such as an infrared laser sensor (TF02-X) or a magnetic induction sensor.

[0054] In one embodiment, Figure 1 As shown, the underground garage entrance and exit safety guidance system also includes a stationary target detection sensor 7, which is connected to the controller 1 and is used to detect whether there are pedestrians or vehicles staying in the blind corner of the blind road section 4; wherein,

[0055] The controller 1 is also connected to the stationary object detection sensor 7 and is also used to control the indicator light 3 of the corresponding entrance and exit 6 to work when the stationary object detection sensor 7 detects that a pedestrian or vehicle is parked at a blind corner of the blind road section 4.

[0056] In this way, when there is a vehicle or pedestrian parked at the blind corner of the blind road section 4, the vehicle driver can also be aware and drive carefully.

[0057] It should be noted that, in order to facilitate the distinction between the moving target 5 and the stationary target (pedestrian or vehicle) at the blind corner of the blind channel, the indicator light 3 may work differently in the two situations. The stationary target detection sensor 7 may be an infrared sensor or the like.

[0058] The solutions involved in the above embodiments are described in detail below in conjunction with specific embodiments.

[0059] Example 1

[0060] like Figure 2 As shown, the blind spot section 4 is a curve 4a with two entrances and exits 6. Each entrance and exit 6 is respectively equipped with a displacement sensor 2 and an indicator light 3. The displacement sensor 2 is installed in the indicator light 3 of the entrance and exit 6 where it is located. The displacement sensor 2 and the indicator light 3 are respectively wirelessly connected to the controller 1.

[0061] like Figure 2 (a) and Figure 2 As shown in (b), when the displacement sensor 2 of only one entrance and exit 6 detects that a moving target 5 enters the curve 4a, only the indicator light 3 of the entrance and exit where the displacement sensor 2 detects that a moving target 5 enters the curve 4a lights up red, and the other indicator lights 3 do not work (do not light up).

[0062] like Figure 2 As shown in (c), when the displacement sensors 2 of the two entrances and exits 6 detect that a moving target 5 enters the curve 4a, the indicator lights 3 of the two entrances and exits 6 turn on red. The time the red light turns on can be determined according to the length of the curve 4a, etc.

[0063] like Figure 2 As shown in (d), when the displacement sensors 2 of the two entrances and exits 6 do not detect that the moving object 5 enters the curve 4a, the indicator lights of the two entrances and exits 6 do not work (do not light up).

[0064] like Figure 2As shown, in order to maximize the possibility that moving objects 5 at both entrances and exits 6 can simultaneously see the indications of the indicator lights 3 at both entrances and exits 6, the indicator lights 3 at both entrances and exits 6 of the curve 4a are installed on the outer side of the curve 4a. Of course, if the curve 4a is relatively long, multiple indicator lights 3 at each entrance and exit 6 can be installed at intervals.

[0065] Example 2

[0066] The blind spot road 4 is a multi-intersection special-shaped road, which can be a T-shaped road 4b, a Y-shaped road, a cross-shaped road 4c, or even a star-shaped road. The T-shaped road 4b and the Y-shaped road each have three entrances and exits 6, the cross-shaped road 4c has four entrances and exits 6, and the star-shaped road has at least five entrances and exits 6. Figure 3 Shown is a T-shaped road 4b, Figure 4 The following is a cross-shaped road. Figure 3 and Figure 4 , the T-shaped road 4b and the cross-shaped road 4c are introduced in detail.

[0067] like Figure 3 As shown, the blind spot section 4 is a T-shaped road 4b with three entrances and exits 6. Each entrance and exit 6 is respectively equipped with a displacement sensor 2 and an indicator light 3. The displacement sensor 2 is installed in the indicator light 3 of the entrance and exit 6 where it is located. The displacement sensor 2 and the indicator light 3 are respectively wirelessly connected to the controller 1.

[0068] like Figure 3 As shown in (a), when the displacement sensor 2 of only one entrance and exit 6 detects that a moving target 5 enters the curve 4a through the entrance and exit 6 where it is located, only the indicator light 3 of this entrance and exit lights up red, and the time the red light is on depends on the length of the road section of this entrance and exit. The indicator lights of the other two entrances and exits 6 do not work (do not light up).

[0069] like Figure 3 As shown in (b), when the displacement sensors 2 of two entrances and exits 6 detect that a moving target 5 enters the curve 4a, the indicator lights 3 of the two entrances and exits 6 turn on red. The duration of the red light can be determined according to the length of the corresponding entrance and exit section, etc. The indicator light of the other entrance and exit 6 does not work (does not light up).

[0070] like Figure 3 As shown in (c), when the displacement sensors 2 of the three entrances and exits 6 detect that a moving target 5 enters the T-shaped road 4b, the indicator lights 3 of the three entrances and exits 6 turn on red. The duration of the red light can be determined according to the length of the corresponding entrance and exit section, etc.

[0071] like Figure 3 As shown in (d), when the displacement sensors 2 of the three entrances and exits 6 do not detect that the moving object 5 enters the T-shaped road 4b, the indicator lights of the three entrances and exits 6 are all turned off.

[0072] like Figure 3 As shown, the T-shaped road 4b includes a main road 41b and a branch road 42b perpendicular to or obliquely intersecting the main road 41b, and the branch road 42b terminates at the intersection with the main road 41b; in order to enable the moving targets 5 at the three entrances and exits 6 to see the indications of the indicator lights 3 of the three entrances and exits 6 at the same time as much as possible, the indicator lights 3 of the two entrances and exits 6 of the main road 41b are installed on the side of the main road 41b away from the branch road 42b.

[0073] like Figure 4 As shown, the blind spot section 4 is a cross-shaped road 4 c having four entrances and exits 6 .

[0074] like Figure 4 As shown, each entrance and exit 6 is respectively equipped with a displacement sensor 2 and an indicator light 3 . The displacement sensor 2 is installed in the indicator light 3 of the entrance and exit 6 where it is located. The displacement sensor 2 and the indicator light 3 are respectively wirelessly connected to the controller 1 .

[0075] like Figure 4 As shown in (a), when the displacement sensor 2 of only one entrance and exit 6 detects that a moving target 6 enters the cross-shaped road 4b through the entrance and exit 6 where it is located, the indicator light 3 of the entrance and exit 6 turns red, and the time the red light turns on depends on the length of the entrance and exit section. The indicator lights of the other three entrances and exits 6 do not work (do not light up).

[0076] like Figure 4 As shown in (b) and 4(c), when the displacement sensors 2 of two or three of the entrances and exits 6 detect that a moving target 6 has entered the cross-shaped road 4b, the indicator lights 3 of these two or three entrances and exits 6 turn on red lights or flash red lights. The time the red lights are on depends on the length of the corresponding entrance and exit road section. The indicator lights 3 of the remaining entrances and exits 6 do not work (do not light up).

[0077] like Figure 4 As shown in (d), when the displacement sensors 2 of the four entrances and exits 6 detect that a moving target 6 enters the T-shaped road 4b, the indicator lights 3 of the four entrances and exits 6 turn on red, and the time the red light turns on is determined according to the length of the corresponding entrance and exit section.

[0078] like Figure 4 As shown in (e), when the displacement sensors 2 of the four entrances and exits 6 do not detect that a moving object 6 enters the T-shaped road 4b, the indicator lights of the four entrances and exits 6 are all turned off.

[0079] Example 3

[0080] The difference between this embodiment and the first embodiment is that the blind spot section 4 is an uphill and downhill road and also has two entrances and exits 6 .
