Description

TECHNICAL FIELD

[0001] The utility model relates to the field of underground passage safe traffic, concretely relates to an underground passage safety induction red green light system and light source opening and closing system. BACKGROUND

[0002] The light is generally dim in the underground passage (especially the underground garage access passage), and most of them have blind area sections such as curved roads and / or turns and / or ups and downs and / or T-shaped roads and / or Y-shaped roads and / or crossroads and / or star-shaped roads, which causes great inconvenience for drivers to enter and exit the underground garage.

[0003] For two-way underground passages, this inconvenience is even more exacerbated. Due to dim light and limited visibility in blind area sections, drivers and pedestrians do not know whether there are pedestrians or vehicles on the opposite lane, usually driving slowly, resulting in prolonged time to enter and exit the underground garage; and traffic conflicts, collisions, scratches, and scratches are likely to occur.

[0004] To solve this problem, the applicant of the present patent previously applied for a patent with the patent name of "underground garage access passage safety induction system" with the application number of 202422550987.6 and a patent with the patent name of "safety induction light source opening and closing system for underground passages" with the application number of 202422881466.9. Both of these two patents install displacement sensors at each entrance and exit of the blind area section, detect whether a moving target enters the blind area section through each displacement sensor, and control the indicator light according to the feedback of each displacement sensor to prompt the situation of the opposite lane of the blind area section.

[0005] However, in these two patents, at least one displacement sensor needs to be configured at each entrance and exit, resulting in a relatively large number of sensors, and the probability of sensor failure is relatively high. When an individual displacement sensor fails, it may not affect the use of the entire system, so it may not be discovered in time, but this situation may cause the indicator light to indicate incorrectly, which can more easily affect the safety of vehicle and pedestrian traffic and affect the user experience. In addition, due to the large number of displacement sensors, the equipment cost is high, and the efficiency is relatively low during the installation of the system and the regular inspection and maintenance process. SUMMARY

[0017] The controller is also connected to the anti-interference detection device, and is used for determining that there is a stationary target at the entrance and exit when the scanning detection device detects that the stationary target at the entrance and exit is more than the stationary target at the parking space corresponding to the scanned area of the entrance and exit.

[0076] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0077] Example 1: As Figure 1 to Figure 5 As shown, an underground passage safety guidance traffic light system includes a controller 1, at least one scanning detection device 2, and at least two indicator lights 3; wherein,

[0078] The underground passage has a blind spot section 4, which has at least two entrances / exits 40, and each entrance / exit 40 is equipped with at least one indicator light 3;

[0079] The scanning and detection device 2 is used to scan and detect whether there is a moving target 6 entering the blind spot section 4 at each entrance / exit 40;

[0080] The controller 1 is connected to the scanning detection device 2 and all indicator lights 3 respectively, and is used to control all indicator lights 3 of the entrance / exit 40 to turn green or flash green when there is a moving target 6 entering the blind spot section 4 at only one entrance / exit 40.

[0081] When a moving target 6 enters the blind spot section 4 at at least two entrances 40, the indicator lights 3 of the at least two entrances 40 are controlled to turn red or flash red, and the indicator lights 3 of the other entrances 40 are controlled to turn green or flash green.

[0082] Specifically, in this embodiment, the scanning detection device 2 scans and detects whether a moving target 4 enters the blind spot road segment 4 at each entrance / exit 40. Therefore, fewer detection devices are needed to detect the situation at each entrance / exit 40 of the blind spot road segment 4, saving on the number of detection devices and equipment costs. Because the number of detection devices is relatively small, the possibility of any detection device malfunctioning is much lower, improving the reliability of use. Furthermore, if any detection device malfunctions, at least two entrances / exits 40 will not be detected, which will affect the operation of the entire system. Therefore, it can be detected and repaired in a timely manner, without causing significant impact on use. This avoids the safety accident caused by the indicator light 3 giving incorrect indications due to the failure to detect the malfunction of a detection device. In addition, the use of fewer detection devices in this embodiment can improve the efficiency of installation, subsequent periodic inspections, and maintenance.

[0083] The indicator light 3 in the embodiment prompts the opposite lane of the blind area road section 4 to have no moving target 6 through the bright green light or the green light flickering, so as to reduce the nervous and uneasy emotions of the pedestrians and the drivers of the vehicles due to the blocked vision and the poor light, and to smoothly pass through the blind area road section 4; the indicator light 3 prompts the opposite lane of the blind area road section 4 to have the moving target 6 through the bright red light or the red light flickering, so as to prompt the pedestrians and the drivers of the vehicles to slowly, normally and safely move forward, and to avoid accidents. Therefore, the embodiment can well play a prompting and guiding role on the vehicles and the pedestrians entering the blind area road section 4 of the underground garage access passage, and can assist the pedestrians and the vehicles to safely pass through the blind area road section 4 of the underground garage access passage, in particular, the underground garage access passage. Moreover, through the light indication, the propagation range is wide, and it is easy to be perceived. The drivers and the pedestrians do not need to pay too much attention, and can know the situation of the opposite lane of the blind area road section 4. The guiding system has low cost, simple and easy-to-understand guiding rules, and is easy to implement and popularize.

[0084] In one embodiment, the controller 1 is further configured to control all the indicator lights 3 to be turned off when all the entrances and exits 40 do not detect any moving target 6 entering the blind area road section 4. In this way, the power consumption can be saved.

[0085] In the embodiment, the scanning detection devices 2 are generally installed at the convergence positions of the respective entrances and exits 40 which are scanned and covered by the scanning detection devices 2. Each scanning detection device 2 scans and covers at least two entrances and exits 40. The number of the scanning detection devices 2 is determined according to the specific situation of the blind area road section 4 and the scanning coverage range of a single scanning detection device 2, so as to ensure that each entrance and exit 40 can be scanned and covered. In most scenarios, one scanning detection device 2 can be installed. For the scenarios with limited vision, the number of the scanning detection devices 2 needs to be appropriately increased.

[0086] The moving target 6 can be a driving vehicle, and can also be a pedestrian, and can even be an animal such as a cat or a dog. The controller 1 can be wirelessly connected with the scanning detection devices 2 and all the indicator lights 3 through a Mesh network or the like. The controller can be an MCU such as an STM32F103RCT6 or an FPGA or the like. When the controller 1 controls the indicator light 3 of the corresponding entrance and exit 40 to flicker in red, the controller 1 can also control the red light flickering frequency according to the distance between the moving target 6 of the entrance and exit 40 and the convergence position of the entrance and exit 40. Specifically, the closer the moving target 6 is to the convergence position of the entrance and exit 40, the higher the red light flickering frequency of the indicator light 3 of the entrance and exit 40, so that the pedestrians and the drivers of the vehicles can more accurately know the situation of the moving target 6 of the opposite lane of the blind area road section 4.

[0087] In the embodiment, the number of the indicator light 3 of each entrance 40 is determined according to the length of the entrance 40. When the width of the entrance 40 is wide, the indicator light 3 can be arranged on both sides of the entrance 40, so that the indication information of at least one indicator light 3 of each entrance 40 can be seen by the pedestrians or drivers entering the blind area section 4. When the blind area section 4 is long, the corresponding slave machine can be additionally arranged.

[0088] In the embodiment, the scanning detection device 2 can have various structures.

[0089] Firstly, the scanning detection device 2 is a rotary laser radar. The rotary laser radar itself has a rotating characteristic and can scan the surrounding environment by 360 degrees. The model can be OT128 or VLP-16, etc.

[0090] Secondly, the scanning detection device 2 includes a video analysis camera. The video analysis camera itself is designed to have a 360-degree rotating function. The model can be zhanyun-A24 or IPC2258, etc.

[0091] Thirdly, the scanning detection device 2 includes a visual sensor. The scanning coverage angle of the visual sensor can be more than 120°. The model can be DS-2CD7127 or IPC2258, etc.

[0092] In the embodiment, as shown in FIG. 1, the scanning detection device 2 is also used to detect whether there is a stationary target in each entrance 40. The controller 1 is also used to control the indicator light 3 of the entrance 40 with the stationary target to give a prompt. The prompt mode can be alternating flashing of red and blue lights, etc. Figure 1

[0093] In addition, considering the entrances 40 near the underground parking lot of the blind area section 4, parking spaces can be arranged near the entrances 40. If a vehicle is parked in the parking space, the scanning detection device 2 can misjudge the vehicle parked in the parking space as a stationary target and give a false prompt. Therefore, the underground passage safety induction traffic light system further includes an anti-interference detection device 5. The anti-interference detection device 5 is used to detect whether there is a stationary target on the parking space in the scanning area corresponding to each entrance 40. In the embodiment, the anti-interference detection device 5 can be an ultrasonic sensor (DYP-A19, etc.), an infrared laser sensor (TF02-X), a visual sensor, etc.

[0094] The controller 1 is also connected to the anti-interference detection device 5 and is used to determine that there is a stationary target in the entrance 40 when the scanning detection device 2 detects that the stationary targets of the entrance 40 are more than the stationary targets of the parking space in the scanning area corresponding to the entrance 40.

[0095] In the embodiment, the anti-interference detection device 5 can have various types, such as an ultrasonic sensor (DYP-A19, etc.), an infrared laser sensor (TF02-X), a visual sensor, etc.

[0096] ​In this embodiment, there are several types of blind area road section 4.

[0097] Firstly, as shown in Figure 2 , the blind area road section 4 is a curve 4a with two entrances 40.

[0098] As shown in Figure 2 (a) and Figure 2 (b), when there is only one entrance 40 with moving targets 6 entering the curve 4a, the indicator lights 3 of both entrances 40 are green or green flashing. The duration of the green light or green flashing can be determined according to the length of the curve 4a, etc.

[0099] As shown in Figure 2 (c), when both entrances 40 have moving targets 6 entering the curve 4a, the indicator lights 3 of both entrances 40 are red or red flashing. The duration of the red light or red flashing can be determined according to the length of the curve 4a, etc.

[0100] As shown in Figure 2 (d), when both entrances 40 have no moving targets 6 entering the curve 4a, the indicator lights of both entrances 40 are off.

[0101] It should be noted that if the detection of another entrance 40 with moving targets 6 entering the curve 4a is within a preset time before the detection of one entrance 40 with moving targets 6 entering the curve 4a, it is considered that both entrances 40 have moving targets 6 entering the curve 4a. Figure 2 (a) and Figure 2 (b) also meet this restriction, that is, as long as the detection of another entrance 40 with moving targets 6 entering the curve 4a is not within a preset time before the detection of one entrance 40 with moving targets 6 entering the curve 4a, it is considered that only one entrance 40 has moving targets 6 entering the curve 4a.

[0102] As shown in Figure 2 , in order to make the moving targets 6 of both entrances 40 see the indicators of the indicator lights 3 of both entrances 40 as much as possible, the indicator lights 3 of both entrances 40 of the curve 4a are installed on the outer side of the curve 4a. Of course, if the curve 4a is relatively long, the indicator lights 3 of each entrance 40 can be spaced apart into multiple.

[0103] Secondly, the blind area road section 4 is a multi-intersection special-shaped road with at least three entrances 40. The multi-intersection special-shaped road 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 have three entrances 40 respectively, the cross-shaped road 4c has four entrances 40, and the star-shaped road has at least five entrances 40.

[0104] Figure 3 The T-shaped road is shown.

[0105] As Figure 3 (a) As shown, when only one of the exits 40 has a moving target 6 entering the T-shaped road 4b, the indicator light 3 of the three exits 40 is green or green flashing, and the duration of the green or green flashing can be determined according to the length of the corresponding exit 40 of the T-shaped road 4b, etc.

[0106] As Figure 3 (b) As shown, when two of the exits 40 have moving targets 6 entering the T-shaped road 4b, the indicator light 3 of the two exits 40 is red or red flashing, and the duration of the red or red flashing can be determined according to the length of the corresponding exit 40 of the T-shaped road 4b, etc. The indicator light of the other exit 40 is green or green flashing, and the duration of the green or green flashing can be determined according to the length of the T-shaped road 4b, etc.

[0107] As Figure 3 (c) As shown, when all three of the exits 40 have moving targets 6 entering the T-shaped road 4b, the indicator light 3 of the three exits 40 is red or red flashing, and the duration of the red or red flashing can be determined according to the length of the T-shaped road 4b, etc.

[0108] As Figure 3 (d) As shown, when none of the three exits 40 has a moving target 6 entering the T-shaped road 4b, the indicator light 3 of the three exits 40 is off.

[0109] As Figure 3 As shown, the T-shaped road 4b includes a main road 41b and a branch road 42b perpendicular or oblique to the main road 41b, and the branch road 42b ends at the intersection with the main road 41b; in order to enable the moving targets 6 of the three exits 40 to see the indications of the indicator lights 3 of the three exits 40 as much as possible, the indicator lights 3 of the two exits 40 of the main road 41b are installed on the side of the main road 41b away from the branch road 42b.

[0110] In the present T-shaped road 4b, for several exits 40 having moving targets 6 entering the T-shaped road 4b from the exits 40, the judgment method is similar to that of the curved road 4a.

[0111] Figure 4 The cross-shaped road 4c is shown.

[0112] As Figure 4As shown in (a), when a moving target 6 enters the crossroad 4c through only one entrance / exit 40, the indicator lights 3 of the four entrances / exits 40 turn green or flash green. The duration of the green light turning green or flashing green can be determined according to the length of the corresponding entrance / exit 40 of the crossroad 4c.

[0113] like Figure 4 As shown in (b) and 4(c), when a moving target 6 enters the crossroads 4c from two or three of the entrances 40, the indicator lights 3 of these two or three entrances 40 illuminate red or flash red. The duration of the red illumination or flashing red light can be determined based on the length of the crossroads 4c, etc. The indicator lights of the remaining entrances 40 illuminate green or flash green. The duration of the green illumination or flashing green light can be determined based on the length of the corresponding entrance 40 of the crossroads 4c, etc.

[0114] like Figure 4 As shown in (d), when a moving target 6 enters the cross-shaped road 4c at all four entrances 40, the indicator lights 3 of the four entrances 40 will light up red or flash red. The duration of the red light lighting or flashing red can be determined according to the length of the corresponding entrance 40 of the cross-shaped road 4c.

[0115] When no moving target 6 enters the crossroads 4c at any of the four entrances 40, the indicator lights 3 at all four entrances 40 are turned off.

[0116] For roads with multiple entrances / exits 40 where a moving target 6 enters a cross-shaped road 4c, the judgment method is similar to that for curves 4a and T-shaped roads 4b.

[0117] Figure 5 The image shows an I-shaped road 4d with five entrances / exits 40.

[0118] like Figure 5 As shown in (a), when a moving target 6 enters the I-shaped road 4d through only one entrance / exit 40, the indicator lights 3 of the five entrances / exits 40 light up green or flash green. The duration of the green light or flashing green light can be determined according to the length of the corresponding entrance / exit 40 of the I-shaped road 4d.

[0119] like Figure 5 (b) Figure 5 (c) and Figure 5(d) As shown in FIG. 6, when two or three or four of the exits 40 have moving targets 6 entering the cross-shaped road 4c, the indicator lights 3 of the two or three or four exits 40 are turned on red or flash red. The duration of the red light or the red light flashing can be determined according to the length of the cross-shaped road 4d, etc. The indicator lights of the remaining exits 40 are turned on green or flash green. The duration of the green light or the green light flashing can be determined according to the length of the cross-shaped road 4d, etc.

[0120] As shown in FIG. 5, Figure 5 (e) As shown in FIG. 7, when moving targets 6 enter the cross-shaped road 4d through all the five exits 40, the indicator lights 3 of the five cross-shaped roads 4d are turned on red or flash red. The duration of the red light or the red light flashing can be determined according to the length of the cross-shaped road 4d, etc.

[0121] As shown in FIG. 5, Figure 5 (f) As shown in FIG. 8, when no moving targets 6 enter the cross-shaped road 4d through all the five exits 40, the indicator lights 3 of the five exits 40 are turned off.

[0122] For the case that moving targets 6 enter the cross-shaped road 4d through several exits 40, the judgment method is similar to that of the curved road 4a and the T-shaped road 4b.

[0123] Thirdly, the blind area road section 4 is an up-and-down road 4c, which has two exits 40.

[0124] Embodiment Two: The main difference between this embodiment and Embodiment One is that, as shown in FIG. 5, Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in FIG. 5, this embodiment indicates whether moving targets 6 enter the blind area road section 4 through each exit 40 by turning on or off the indicator light 3 of each exit 40. That is, the controller 1 is used to control the indicator light 3 of the exit 40 through which moving targets 6 enter the blind area road section 4 to work, and to control the indicator light 3 of the exit 40 through which no moving targets 6 enter the blind area road section 4 to turn off.

[0125] Specifically, the embodiment works by the indicator light 3, indicating that there is a moving target 6 entering the blind area section 4 from the exit 40 where the working indicator light 3 is located. If all the indicator lights 3 of an exit 40 do not work, it indicates that there is no moving target 6 entering the blind area section 4 from the exit 40. The embodiment can conveniently prompt whether there is a moving target 6 entering each exit 40 of the blind area section 4, thereby well prompting and inducing the vehicles and pedestrians entering the blind area section 4 of the underground passage, assisting the pedestrians and vehicles to safely pass through the underground passage, especially the blind area section 4 of the underground garage exit passage. In addition, the embodiment prompts the opposite lane situation of the blind area section 4 of the underground passage by the on-off of the indicator light 3. The working time of each indicator light 3 is relatively short, the frequency of use is also relatively low, which is energy-saving and can prolong the service life.

[0126] In the embodiment, the indicator light 3 is long or flashing when working. When the indicator light 3 is long, it can be but not limited to red light or yellow light. When the indicator light 3 is flashing, it can be but not limited to red light, yellow light or red and blue light. When the indicator light 3 is flashing, it can also be controlled to flash at different frequencies according to the distance or speed of the moving target 6.

[0127] In the embodiment, the type of the blind area section 4 is various.

[0128] The first type is as shown in Figure 6 , the blind area section 4 is a curve 4a, having two exits 40.

[0129] As shown in Figure 6 (a) and Figure 6 (b), when there is a moving target 6 entering the curve 4a only through one exit 40, the indicator light 3 of the exit 40 where the moving target 6 enters the curve 4a is red, and the other indicator light 3 does not work (not light).

[0130] As shown in Figure 6 (c), when there are moving targets 6 entering the curve 4a through two exits 40, the indicator lights 3 of the two exits 40 are red, and the time of red light can be determined according to the length of the curve 4a.

[0131] As shown in Figure 6 (d), when there are no moving targets 6 entering the curve 4a through two exits 40, the indicator lights 3 of the two exits 40 do not work (not light).

[0132] The second, the blind section 4 is a multi-intersection irregular road with at least three exits 40. The multi-intersection irregular road 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 have three exits 40 respectively, the cross-shaped road 4c has four exits 40, and the star-shaped road has at least five exits 40.

[0133] As shown in Figure 7 The blind section 4 is a T-shaped road 4b with three exits 40.

[0135] As shown in Figure 7 (b) When two exits 40 have moving targets 6 entering the T-shaped road 4b, the indicator lights 3 of these two exits 40 are red and on for a time determined according to the lengths of the road sections of the corresponding exits 40, and the indicator light 3 of the other exit 40 is not working (not on).

[0136] As shown in Figure 7 (c) When three exits 40 have moving targets 6 entering the T-shaped road 4b, the indicator lights 3 of the three exits 40 are red and on for a time determined according to the lengths of the road sections of the corresponding exits 40.

[0137] As shown in Figure 7 (d) When none of the three exits 40 has a moving target 6 entering the T-shaped road 4b, the indicator lights 3 of the three exits 40 are all off.

[0138] Figure 8 The blind section 4 is a cross-shaped road 4c with four exits 40.

[0139] As shown in Figure 8 (a) When only one exit 40 has a moving target 6 entering the cross-shaped road 4c, the indicator light 3 of this exit 40 is red and on for a time determined according to the length of the road section of this exit 40, and the indicator lights of the other three exits 40 are not working (not on).
