Description

Technical Field

[0001] The present invention belongs to the technical field of platform doors, and more specifically, relates to a remote sensing automatic lifting platform door system. Background Art

[0002] Platform doors are a barrier to ensure the safety of passengers waiting for trains. Currently, platform doors are installed in high-speed railway stations, subway stations and other places. By installing platform doors, passengers and trains can be separated when the train enters or leaves the platform. On the one hand, this can protect the safety of passengers and prevent the air flow rate near the train from accelerating due to the movement of the train when the train enters the station, resulting in low air pressure near the train and low air flow rate and high air pressure away from the train. In this way, passengers will be pushed towards the train by the strong air pressure, posing a threat to their safety. On the other hand, it can improve the efficiency of traffic organization and optimize the platform waiting environment.

[0003] In the related art, a telescopic sliding platform door is provided. When a train enters the platform, the two door bodies on both sides of the telescopic sliding platform door can move away from each other to open the door body and allow passengers to enter. When the train leaves the platform, the two door bodies on both sides can move closer to each other to close the door body. However, a problem with the telescopic sliding platform door is that when the train is not aligned with the door, the entrance and exit area between the door body and the train is reduced, resulting in a decrease in passenger entry and exit efficiency, affecting the train's entry and exit efficiency. At the same time, the telescopic sliding platform door cannot adapt to a variety of train lengths, and staff at the service desk need to coordinate the order and position of trains of different lengths entering the station.

[0004] In the related art, a lifting guardrail platform door is also proposed. The top of the lifting guardrail platform door is connected to the top of the platform. The lifting guardrail platform door solves the problem of accurate door alignment by lifting multiple door bodies. However, the lifting guardrail platform door has poor protection effect, is not resistant to wind pressure, and is prone to hitting passengers during the descent of the door body. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a remote sensing automatic lifting platform door system, which detects the speed changes of the train through the speed acquisition module to determine the train's entry and exit status, and sends entry and exit signals. The system passes a preset distance through the distance acquisition unit. When the distance between the train and the distance acquisition unit is less than the preset distance, the train blocks the distance acquisition unit, and judges the train's composition information based on the number and combination of the distance acquisition units blocked by the train, and sends a train composition signal. The processing module controls the lifting and lowering status of different numbers of door bodies according to the entry and exit signals and the train composition signals, so that the door bodies can be accurately aligned with the doors of trains with different compositions entering and exiting the station.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a remote sensing automatic lifting platform door system is provided, including a platform door body, an identification module, a detection module, an emergency module, a processing module and a drive module.

[0012] Furthermore, the detection module includes an infrared radiation device, which is arranged at the bottom of the anti-collision pad. The infrared radiation device is used to obtain the distance information between the bottom of the anti-collision pad and the target to be measured in the vertical direction. The infrared radiation device is preset with a safety distance. When the distance information is less than the safety distance, the infrared radiation device generates a detection signal corresponding to the distance information.

[0017] The drive module is also equipped with a ball screw, which is used to convert the torque of the drive motor and the backup motor into a pulling force and transmit the pulling force smoothly. The ball screw can be self-locking so that the door leaf will not drop due to its own weight.

[0024] Furthermore, the door body also includes door leaves and door windows. Both sides of the door leaves are arranged in the guide rails, and the doors and windows are embedded in the door leaves. The material of the doors and windows is PC endurance board. The surface of the PC endurance board is composite co-extruded to form an anti-ultraviolet composite co-extruded layer. The PC layer of the PC endurance board and the anti-ultraviolet composite co-extruded layer are independent of each other.

[0025] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0026] 1. The remote sensing automatic lifting platform door system of the present invention realizes the lifting of the door body by snapping the door body into the guide rails of the columns on both sides of the door body. With this arrangement, on the one hand, since the columns are fixed to the ground, the structural strength of the door body snapped into the guide rails is improved, and when the train enters or leaves, it can withstand wind pressure without the door body shaking or even being damaged. On the other hand, due to the existence of the guide rails, the door body runs more smoothly when lifting and lowering.

[0027] 2. The remote sensing automatic lifting platform door system of the present invention detects the speed change of the train through the speed acquisition module to determine the train's entry and exit status, and sends entry and exit signals. It passes through a preset distance through the distance acquisition unit. When the distance between the train and the distance acquisition unit is less than the preset distance, the train blocks the distance acquisition unit, and judges the train's composition information based on the number and combination of the distance acquisition units blocked by the train, and sends a train composition signal. The processing module controls the lifting and lowering status of different numbers of door bodies according to the entry and exit signals and the train composition signals, so that the door bodies can be accurately aligned with the doors of trains with different compositions entering and exiting the station.

[0028] 3. The remote sensing automatic lifting platform door system of the present invention forms a detection network in the area where the passenger enters the platform door body by detecting the distance information and contact information between the platform door and the passenger on the platform door body, so as to perform multi-directional safety detection on the passengers, adapt to passengers of different heights and body shapes, and avoid the door body hitting the passengers during the descent process.

[0029] 4. The remote sensing automatic lifting platform door system of the present invention forms an anti-UV composite co-extrusion layer by composite co-extrusion of the PC endurance board surface of the vehicle window, which enables the PC endurance board to resist ultraviolet erosion. At the same time, since the PC layer and the anti-UV layer are independent of each other, the PC layer and the anti-UV layer can not interfere with each other, which makes the service life of the vehicle window longer than the coating process and mixed co-extrusion.

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0041] The present invention provides a remote sensing automatic lifting platform door system 10 , which includes a platform door body 11 , an identification module 12 , a detection module 13 , an emergency module 14 , a processing module 15 and a driving module 18 .

[0042] The platform door body 11 includes at least two columns 111, a door body 112, and a crossbeam 113. The columns 111 are provided, each of which is provided with a guide rail 1111. Both sides of the door body 112 are located within the guide rails 1111. One side of the crossbeam 113 is located at the top of the platform, and the other side is connected to the two columns 111. It is understood that the remote sensing automatic lifting platform door system of the present invention achieves the lifting and lowering of the door body 112 by engaging the door body 112 into the guide rails 1111 of the columns 111 on both sides of the door body 112. This arrangement, on the one hand, improves the structural strength of the door body 112 engaged in the guide rails 1111 because the columns 111 are fixed to the ground, allowing it to withstand wind pressure without shaking or even damage when a train enters or leaves. On the other hand, the presence of the guide rails 1111 allows the door body 112 to operate more smoothly during lifting and lowering, and can be raised and lowered in a straight line. It is worth noting that the lifting platform safety door system 10 of the present invention is not limited to this. A brush 1116 is provided around the guide rail 1111. The brush 1116 can prevent foreign matter or rainwater from entering the guide rail 1111 and can clean the guide rail 1111 in real time to improve the cleanliness of the contact position between the door body 112 and the guide rail 1111, thereby preventing passengers from touching the contact position and getting their clothes dirty.

[0043] Furthermore, the platform door body 11 is made of a nano-modification process, so that the platform door body 11 can be corrosion-resistant, acid- and alkali-resistant, impact-resistant, aging-resistant and UV-resistant, thereby increasing the service life of the platform door body 11.

[0044] Furthermore, the identification module 12 is provided on the platform door body 11. The identification module 12 is used to identify train information and, in combination with the train information, issues corresponding identification signals. The train information includes train composition information and train entry and exit status. It is understood that the lifting platform safety door system 10 of the present invention identifies trains based on train composition information and entry and exit status. For example, in this embodiment, the train composition information includes two types: an 8-car train and a 16-car train, and the train entry and exit status includes an entry state and an exit state. In other words, the identification module 12 can issue four different identification signals: an 8-car train entry signal, an 8-car train exit signal, a 16-car train entry signal, and a 16-car train exit signal. The processing module 15 issues different control instructions based on the different identification signals. It is worth noting that the lifting platform safety door system 10 of the present invention is not limited to this. The train composition information and train entry and exit status can be adaptively adjusted according to actual needs.

[0045] Furthermore, multiple detection modules 13 are provided, each of different types, at different locations on the platform door body 11 to obtain detection information from different directions on the platform door body 11 and generate corresponding detection signals based on this detection information. The detection information includes contact information and distance information. This configuration has the advantage of being able to obtain distance and contact information from the platform door body 11 to passengers in different directions. In this embodiment, multiple detection modules 13 detect the vertical and radial directions of the lift platform door, forming a detection network within the area where passengers enter the platform door body 11. The detection modules 13 determine safety based on contact with and distance from the passenger, and transmit detection signals to the processing module 15. The processing module 15 then generates different control instructions based on the different detection signals. This configuration can accommodate passengers of different heights and body shapes, avoiding missed detections due to passengers being out of the vertical detection range or due to the detection module 13 not making contact with the passenger, thereby improving safety. By providing a plurality of different detection modules 13 at the same time, it is possible to prevent the remote sensing automatic lifting platform door system from being unable to obtain detection information when one detection module 13 fails.

[0046] Furthermore, the emergency modules 14 are provided in plurality, and the plurality of emergency modules 14 are arranged in a plurality of different positions. The emergency modules 14 are used to make emergency handling at multiple points for raising and lowering the door body 112. It is understood that providing a plurality of emergency modules 14 and arranging them in different positions can improve the fault tolerance rate and can prevent the emergency modules 14 from malfunctioning or being damaged and being unable to respond when the door body 112 malfunctions.

[0047] Furthermore, the processing module 15 executes the control instructions associated with the identification signal according to the identification signal, and executes the control instructions associated with the number of detection signals according to the number of times the detection signal is received. For example, if the identification signal is an 8-car train entering the station signal, the door body 112 corresponding to the 8-car train is controlled to rise; if the identification signal is a 16-car train leaving the station signal, the door body 112 corresponding to the 16-car train is controlled to fall; if one detection signal is received, the door body 112 is immediately controlled to rise and fall after a delay; if the detection signal is received multiple times, all the door bodies 112 are controlled to rise to protect the passengers. It is worth noting that the delay time and the number of times the detection signal is received can be changed according to the actual situation. Preferably, the processing module can be a control board 151.

[0048] Furthermore, the driving module 18 performs the lifting and lowering of the door body 112 according to the control instructions. It can be understood that the driving module 18 is the power output unit of the lifting platform safety door system 10 of the present invention, which is used to control the lifting and lowering of the door body 112.

[0049] Furthermore, the identification module 12 includes a speed acquisition unit 121 and a distance acquisition unit 122. The identification signal includes an entry and exit signal and a train formation signal. The speed acquisition unit 121 is provided on the crossbeam 113. The speed acquisition unit 121 is used to acquire the real-time speed of the train and identify the entry and exit status of the train based on the change in the real-time speed. It can be understood that the remote sensing automatic lifting platform door system of the present invention detects the speed change of the train through the speed acquisition unit 121 to determine the entry and exit status of the train and sends out the entry and exit signal. For example, when the speed of the train gradually decreases, it can be considered that the train is in the entry state, and when the speed of the train gradually increases, it can be considered that the train is in the exit state. It is worth noting that after obtaining the real-time speed of the train for the first time, the real-time speed of the train is obtained for the second time with a delay. In this way, it is possible to avoid non-stop trains interfering with the lifting platform safety door system 10.

[0050] Furthermore, multiple distance collection units 122 are provided, and the multiple distance collection units 122 are spaced apart on the crossbeam 113. The multiple distance collection units 122 can block the train, and the distance collection units 122 determine the train's formation information based on the number and combination of the distance collection units 122 blocked by the train. It can be understood that the distance collection units 122 are based on a preset distance. When the distance between the train and the distance collection unit 122 is less than the preset distance, it can be considered that the train blocks the distance collection unit 122. At the same time, because the multiple distance collection units 122 are spaced apart on the crossbeam 113, the train's formation information can be determined based on the number and combination of the distance collection units 122 blocked by the train, and a train formation signal can be issued. For example, in this embodiment, there are two trains of different lengths, an 8-car train and a 16-car train. We can set, for example, 16 distance collection units 122. The 16 distance collection units 122 are spaced apart and set corresponding to the train. When the 8-car train enters, the corresponding 8 distance collection units 122 are blocked. At this time, according to the number of blocked distance collection units 122 being 8, and 8 units, it can be judged that the train's composition information is 8-car composition. When the 16-car train enters, the corresponding 16 distance collection units 122 are blocked. At this time, according to the number of blocked distance collection units 122 being 16, it can be judged that the train's composition information is 16-car composition. It is worth noting that the train's composition information can only be determined when and only when all the distance collection units 122 corresponding to the train length are blocked, so as to avoid the situation where only one distance collection unit 122 or several distance collection units 122 are accidentally touched due to external factors. That is, the identification signal can only be sent when the distance collection units 122 corresponding to the train length are blocked in combination, thereby improving the reliability of the distance collection unit 122 in judging the train composition. Of course, the actual number of distance collection units 122 can be adjusted according to the actual situation.

[0051] Furthermore, the door body 112 is provided with an anti-collision cushion 1121, which is capable of deformation. The anti-collision cushion 1121 is provided at the bottom of the door body 112 and is arranged along the length of the door body 112. The anti-collision cushion 1121 is hollow to form a cavity 11211. It can be understood that the function of the anti-collision cushion 1121 is to prevent the door body 112 from hitting the passengers during the descent process. Arranging the anti-collision cushion 1121 along the length of the door body 112 can cover the entire space at the bottom of the door body 112 to increase the protection area. The hollow cavity 11211 can offset part of the impact force by deforming the anti-collision cushion 1121 during a collision.

[0052] Furthermore, the door body also has a non-Newtonian fluid 16, which is arranged along the length of the door body 112 and is arranged in the cavity 11211. It is worth noting that compared with general elastic materials, the non-Newtonian fluid 16 can convert the energy generated by the impact into heat to dissipate it, instead of converting the energy generated by the impact into elastic potential energy like general elastic materials. The elastic potential energy will still act on the human body, resulting in insignificant protection and buffering effects, and the human body will still be injured. At the same time, the non-Newtonian fluid 16 can be used in an environment of -40°C to 70°C. Under the same environment, general elastic materials will cause elastic deformation failure due to temperature reasons, and thus no longer have the buffering function. In addition, the non-Newtonian fluid 16 is resistant to hydrolysis and tearing, that is, it has a longer service life.

[0053] Furthermore, the detection module 13 includes an air pressure sensor 131, which is arranged in the cavity 11211. When the cavity 11211 is impacted, the internal air pressure will change. The air pressure sensor 131 can respond according to the change in air pressure to obtain contact information in the vertical direction of the door body 112. The air pressure sensor 131 generates a detection signal corresponding to the contact information. It can be understood that when the anti-collision cushion 1121 contacts the human body, the anti-collision cushion 1121 will deform and shrink, so that high-pressure gas will be formed in the cavity 11211. The air pressure sensor 131 senses the change in air pressure and can respond. The advantage of using the air pressure sensor 131 is that, on the one hand, compared with the method of using a pressure sensor to detect whether there is contact with the passenger and respond, it can avoid contact with the passenger and cause secondary damage to the passenger, that is, judging whether the door body 112 is in contact with the passenger by the change in air pressure. On the other hand, compared with setting multiple pressure sensors at the bottom of the door body 112 to increase the detection area of ​​the pressure sensor and avoid missed detection, the air pressure sensor 131 generates a detection signal based on the change in air pressure in the cavity 11211. Therefore, only one air pressure sensor 131 is needed to detect whether the entire door body 112 is in contact with the passenger. It is not only efficient and has lower production costs, but also the detection accuracy of the air pressure sensor 131 is higher and the response is faster.

[0054] Furthermore, the detection module 13 includes an infrared radiation device 132, which is arranged at the bottom of the anti-collision pad 1121. The infrared radiation device 132 is used to obtain the distance information between the bottom of the anti-collision pad 1121 and the target to be measured in the vertical direction. The infrared radiation device 132 is preset with a safety distance. When the distance information is less than the safety distance, the infrared radiation device 132 generates a detection signal corresponding to the distance information. It can be understood that by setting up the infrared radiation device 132 and presetting the safety distance, before the door body 112 contacts the passenger, it is possible to improve the judgment of whether the distance between the door body 112 and the passenger is within the safety distance. On the one hand, before the door body 112 contacts the passenger, it can improve the warning and further improve the safety to avoid the passenger from being hit. On the other hand, compared with the existing method of setting an infrared sensor under the door body 112 to judge when the door body 112 is descending, when the passenger passes through the door body 112, the infrared sensor immediately sends a detection signal. The method of presetting the safety distance through the infrared radiation device 132 is more intelligent. For example, if the passenger passes through the door body 112 during the descent of the door body 112, but passes through the door body 112 at a faster time, and at this time the distance between the passenger and the door body 112 is greater than the safety distance, the infrared radiation device 132 does not generate a detection signal. This is more targeted to avoid the increase in manpower and material costs caused by degree protection.

[0055] Furthermore, the detection module 13 also includes a first infrared sensor 133 and a second infrared sensor 134. The first infrared sensor 133 is arranged on the front side of the column 111. The first infrared sensor 133 is spaced apart from the front side of the column 111. The first infrared sensor 133 is also spaced apart from the bottom of the column 111. The first infrared sensor 133 is used to obtain contact information in the vertical direction of the column 111 and generate a corresponding detection signal. In this embodiment, we refer to the side of the column 111 facing the platform as the front side of the column 111. It can be understood that arranging the first infrared sensor 133 on the front side of the column 111 can prevent passengers entering the train when the door body 112 descends from entering the lower side of the door body 112 during the descent and then colliding with the passengers. At the same time, the first infrared sensor 133 is spaced apart from the front side of the column 111 to avoid early warning when passengers have passed by, and to warn passengers in advance before there is a distance from the door body 112. In addition, the first infrared sensor 133 is spaced apart from the bottom of the column 111 to avoid missed detection when a passenger lifts his legs.

[0056] Furthermore, the second infrared sensor 134 is arranged on the rear side of the column 111. The second infrared sensor 134 is spaced apart from the rear side of the column 111. The second infrared sensor 134 is also spaced apart from the bottom of the column 111. The second infrared sensor 134 is used to obtain contact information in the vertical direction of the column 111 and generate a corresponding detection signal. In this embodiment, we refer to the side of the column 111 facing the train as the rear side of the column 111. It can be understood that arranging the second infrared sensor 134 on the rear side of the column 111 can prevent passengers leaving the train from entering the lower side of the door body 112 during the descent when the door body 112 is lowered, and then colliding with the passengers. At the same time, the second infrared sensor 134 is spaced apart from the rear side of the column 111, which can avoid early warning when the passengers have passed the second infrared sensor 134, and can warn the passengers in advance before there is a distance from the door body 112. In addition, the second infrared sensor 134 is spaced apart from the bottom of the column 111, which can avoid missed detection when the passenger lifts his legs.

[0057] Furthermore, the drive module 18 includes a drive motor 181 and a drive battery 182. The drive motor 181 and the drive battery 182 are arranged in the column 111. The number of drive motors 181 corresponds to the number of door bodies 112. Each drive motor 181 controls the lifting and lowering of each door body 112. It can be understood that in this embodiment, one drive motor 81 controls one door body 112. The advantage of such an arrangement is that it can achieve flexible control of each door body 112, so as to avoid the need to control the lifting of all door bodies 112 when one door body 112 has an operating problem. At the same time, when one door body 112 is damaged, it will cause all door bodies 112 to be unusable.

[0058] Furthermore, the drive module 18 also includes a backup battery and a backup motor, which are located away from the column 111 and are used for emergency response. It will be appreciated that the redundant design of the backup motor and backup battery ensures the normal operation of the platform lift safety door in the event of a problem with the operating drive motor or drive battery, thereby improving the reliability of the platform lift safety door.

[0059] Furthermore, the drive module 18 is equipped with a ball screw 183, which is used to convert torque into tension and smoothly transmit this tension. The use of the ball screw 183 not only converts the motor's torque into the tension required to raise and lower the safety door, but also ensures smooth and quiet transmission, enhancing the passenger experience. Furthermore, due to the high friction coefficient of the ball screw, if the drive motor 181 stops after the door leaf 1122 rises, the ball screw will self-lock, preventing the door leaf 1122 from descending due to its own weight.

[0060] Furthermore, a pulley 1112, a chain 1113, and a counterweight 1114 are provided on the column 111. The pulley 1112 is provided at the top of the column 111, and the counterweight 1114 is provided on the side facing away from the door body 112. The chain 1113 is connected to the door body 112 at one end via the pulley 1112, and to the counterweight 1114 at the other end. It will be appreciated that the provision of the counterweight 1114 prevents the door body 112 from descending due to the weight of the counterweight 1114 if the drive motor 181 fails, thereby improving the safety of the lift platform safety door system 10 of the present invention.

[0061] Furthermore, the present invention has two counterweights 1114, which are respectively arranged in the columns 111 on both sides of the door body 112. The mass of the two counterweights 1114 is greater than half of the mass of the door body 112, so as to lift the door body 112. It can be understood that compared to lifting the door body 112 by using a single counterweight 1114, the two counterweights 1114 can balance the mass of the door body 112, so that the force on the door body 112 is balanced, thereby avoiding the door body 112 being subjected to a single force, which reduces the service life of the door body 112.

[0062] Furthermore, a safety rope 1115 is provided on the upright 111. The safety rope 1115 is arranged parallel to the chain 1113 on both sides of the pulley 1112. The safety rope 1115 is connected to the door body 112 at one end through the pulley 1112, and to the configuration block at the other end. It can be understood that by using the safety rope 1115 and the chain 1113 simultaneously, this redundant design can ensure that the door body 112 does not fall even if the chain 1113 fails.

[0063] Furthermore, the emergency module 14 includes a PSL control unit 141, a PEC control unit 142, an LCB control unit 143 and a manual control unit 144. The PSL control unit 141 is arranged on the platform. The PSL control unit 141 can control the lifting and lowering of all the door bodies 112 when the lifting and lowering of the door body 112 is abnormal. The PEC control unit 142 is arranged on the service station. The PSL control unit 141 can control the lifting and lowering of all the door bodies 112 when the lifting and lowering of the door body 112 is abnormal. The LCB control unit 143 is arranged on the column 111. The PSL control unit 141 can isolate a single door body 112 when the lifting and lowering of the door body 112 is abnormal. There are multiple manual control units 144, and multiple manual control units 144 are arranged on the platform door body 11. The manual control unit 144 can be manually unlocked to control the lifting and lowering of a single door body 112. It is understandable that compared with passengers, staff have more experience in emergency handling. Setting the PEC control unit 142 at the service desk makes it easier for staff to make unified adjustments and make emergency handling. Setting the manual control unit 144 can make emergency handling manually when the drive motor fails.

[0064] Furthermore, the door body 112 also includes door panels 1122 and door windows 1123. Both sides of the door panels 1122 are arranged in the guide rails 1111, and the door windows 1123 are embedded in the door panels 1122. The material of the door windows 1123 is PC endurance board, and the surface of the PC endurance board is compositely co-extruded to form an anti-ultraviolet composite co-extruded layer. It is worth noting that the PC endurance board is transparent. When entering and exiting the station, passengers can observe the situation inside the train through the transparent door windows 1123 to obtain the number of passengers on the train in advance. At the same time, compared with the existing transparent PVC board, since the surface of the PC endurance board is compositely co-extruded to form an anti-ultraviolet composite co-extruded layer, the PC endurance board can resist ultraviolet erosion. At the same time, since the PC layer and the anti-ultraviolet layer are independent of each other, the PC layer and the anti-ultraviolet layer can not interfere with each other, which makes the service life of the PC endurance board longer than the coating process and mixed co-extrusion. In addition, the surface of the PC endurance board is hardened to prevent the surface of the PC endurance board from being scratched and affecting its use.

[0065] Furthermore, the lifting platform safety door system 10 is also provided with a prompt module 17, which includes an LED car display screen 171, an information guidance display screen 172, a warning light 173 and a sound unit 174. Among them, the LED car display screen 171 is used to display the car number and prompt content, and the prompt content can be to remind passengers to wait here. The LED car display screen 171 is set according to the stop position of the car. The information guidance display screen 172 is used to provide information guidance, which can be train information, car information, current time information, car distribution information, etc. The warning light 173 is used to issue a warning when the detection module 13 sends a detection signal to remind passengers to pay attention to safety. On the one hand, the sound unit 174 can cooperate with the LED car display screen 171 and the information guidance display screen 172 to issue a sound to remind passengers to wait here and broadcast the train information, car information, current time information and car distribution information, etc. On the other hand, it cooperates with the warning light 173 to issue a business warning when the detection module 13 sends a detection signal to remind passengers to pay attention to safety.

[0066] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
