Description

Technical Field

[0001] The present invention is applied to the background of rail transit vehicle safety, and its name is an alarm device for actively monitoring the gap between the vehicle and the platform. Background Art

[0002] With the rapid development of urban rail transit, people's travel increasingly depends on rail transit. Rail transit greatly facilitates people's travel. As such an important means of travel, the safety of rail transit has attracted wide attention. Among them, the phenomenon that the gap between the station platform and the train is too large, or people or objects are caught in the gap often occurs. Usually, an infrared light curtain is designed to be set in the platform gap. However, the infrared light curtain has many instabilities in the subway operation environment. External factors such as train vibration and light will affect its normal monitoring function, and false alarms are likely to occur, resulting in problems such as train tightening or monitoring failure.

[0003] Therefore, there is a need for an alarm device for actively monitoring the gap between the vehicle and the platform to solve the safety hazards brought by the too large gap between the platform door and the train. Summary of the Invention

[0004] The purpose of the present invention is to provide an alarm device for actively monitoring the gap between the vehicle and the platform to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: An alarm device for actively monitoring the gap between the vehicle and the platform, comprising a platform, a train, a plurality of cameras and a protection component, wherein:

[0006] The train is arranged on one side of the platform, and a plurality of distance sensors are evenly fixed on the side of the platform close to the train;

[0007] The train includes a plurality of train doors, and a plurality of the cameras are fixed on one side of the train;

[0008] A placement groove is formed on the side of the platform close to the train.

[0009] In one embodiment, the protection component includes two sets of first drivers and a connecting plate, wherein:

[0010] The two sets of first drivers are fixed inside the placement groove, the connecting plate is fixed to the output shafts of the two sets of first drivers, a sliding groove is formed on the side of the platform close to the train, one end of the connecting plate is slidably connected to the sliding groove, and infrared irradiators are evenly distributed on the side of the connecting plate close to the train.

[0011] In one embodiment, it further includes a monitoring system, and the monitoring system includes a processing module and an alarm module;

[0012] The processing module includes a comparison unit, an image storage unit, an opening and closing unit, and a calculation unit;

[0013] The image storage unit and the comparison unit are electrically connected to the camera, the distance sensor is electrically connected to the calculation unit, and the calculation unit is electrically connected to the first drive;

[0014] The opening and closing unit controls the opening and closing of the train door. The comparison unit is used to receive the image initially captured by the camera, and the calculation unit controls the operation of the first drive.

[0015] In one embodiment, the processing module includes the following operating steps:

[0016] S1. When the train stops at a platform, the distance between the train and the platform is detected in real time by the distance sensor, and the signal is transmitted to the calculation unit;

[0017] S2. Set the constant distance between the train and the platform as m, which is the appropriate distance between the train and the platform;

[0018] S3. When the distance sensor detects that the distance between the train and the platform is less than or equal to m, it means that the gap between the train and the platform is in an adaptive state;

[0019] S4. When the distance sensor detects that the distance between the train and the platform is greater than m, it means that the gap between the train and the platform has become larger. At this time, the calculation unit transmits the signal to the first drive to control the first drive to extend and drive the connecting plate to extend out of the sliding groove.

[0020] In one embodiment, the alarm module includes an obstacle recognition sub-module, a deviation analysis unit, and a warning sub-module, where:

[0021] The obstacle recognition sub-module is electrically connected to the image storage unit, and the deviation analysis unit is electrically connected to the image storage unit;

[0022] The obstacle recognition sub-module includes a judgment unit, and the judgment unit is electrically connected to the infrared irradiator.

[0023] In one embodiment, the alarm module includes the following operating steps:

[0024] A1. Before the train starts for the first time, the camera takes a photo of the gap between the train and the station, which is photo A, and transmits it to the comparison unit;

[0025] A2. When the train stops at a platform, the camera takes a real-time photo of the gap and transmits it to the image storage unit, which is photo B;

[0026] A3. In the processing module, compare photo B with photo A, transmit the signal to the obstacle recognition sub-module, and judge the size of the obstacle and its danger coefficient through the judgment unit;

[0027] A4. The image storage unit transmits the signal to the deviation analysis unit to judge the position of the camera.

[0028] In one embodiment, A3 includes the following specific operation steps:

[0029] A31. When the obstacle recognition sub-module recognizes that there is no obstacle at the gap, when the train stops, the opening and closing unit normally controls the opening and closing of the train door to facilitate passengers to get on and off normally;

[0030] A32. When the obstacle recognition sub-module recognizes that there is an obstacle at the gap and does not block the infrared irradiator, it means that the obstacle is small, the danger coefficient is low, it is not higher than the platform, and it will not affect the passengers' entry and exit. Repeat step A31;

[0031] A33. When there is an obstacle at the gap and it blocks the infrared irradiator, at this time, the infrared irradiator transmits the signal to the judgment unit, indicating that the obstacle is large, the danger coefficient is high, and it will affect the operation of the protection component;

[0032] A34. The judgment unit then transmits the signal to the warning sub-module.

[0033] In one embodiment, A4 includes the following specific operation steps:

[0034] A41. The deviation analysis unit receives the signal of photo A in the comparison unit and records in advance the shooting angle a of the camera before the train starts;

[0035] A42. The image storage unit then transmits photo B to the deviation analysis unit to analyze the shooting angle b. Thus, the deviation analysis unit compares b with a to judge the shooting angle of the camera.

[0036] In one embodiment, the warning sub-module includes a broadcasting unit.

[0045] Embodiment 1

[0046] Please refer to Figures 1-3 , the present invention provides a technical solution: an alarm device for actively monitoring the gap between a vehicle and a platform: including a platform 1, a train 3, several cameras 2 and a protection component, wherein:

[0047] The train 3 is arranged on one side of the platform 1, and several distance sensors 7 are evenly fixed on the side of the platform 1 close to the train 3;

[0048] The train 2 includes several train doors 11, several cameras 2 are fixed on one side of the train 3, and several cameras 2 are respectively located above several train doors 11 and correspond one by one;

[0049] A placement groove 4 is opened on the side of the platform 1 close to the train 3;

[0050] The train door 11 is slidably connected to one side of the platform 1. When the train 3 stops, the gap between the train 3 and the platform 1 is photographed through the camera 2 to monitor the internal obstacles to ensure the safety of passengers. Then, the distance between the gaps is detected through the distance sensor 7 to determine whether the gap becomes larger;

[0051] The protection component includes two sets of first drivers 5 and a connecting plate 6, where:

[0052] The two sets of first drivers 5 are fixed inside the placement groove 4. The two sets of first drivers 5 are distributed on both sides of the placement groove 4 to facilitate driving the connecting plate 6 to move. The connecting plate 6 is L-shaped. The connecting plate 6 is fixed to the output shafts of the two sets of first drivers 5. A chute 8 is provided on one side of the platform 1 close to the train 3. The chute 8 penetrates through the placement groove 4 to facilitate the connecting plate 6 to move out of the placement groove 4 into the chute 8. One end of the connecting plate 6 is slidably connected to the chute 8. Infrared irradiators are evenly distributed on one side of the connecting plate 6 close to the train 3.

[0053] The first driver 5 can be a hydraulic cylinder;

[0054] When the distance sensor 7 detects that the distance of the gap becomes smaller, it controls the first driver 5 in the placement groove 4 to start, pushing the connecting plate 6 to extend in the chute 8, so that one side of the connecting plate 6 gradually approaches one side of the train 3, thereby reducing the potential safety hazard caused by an overly large gap and fully ensuring the safety of passengers;

[0055] It further includes a monitoring system. The monitoring system includes a processing module and an alarm module;

[0056] The processing module includes a comparison unit, an image storage unit, an opening and closing unit, and a calculation unit;

[0057] The image storage unit and the comparison unit are electrically connected to the camera 2. The distance sensor 7 is electrically connected to the calculation unit. The calculation unit is electrically connected to the first driver 5;

[0058] The opening and closing unit controls the opening and closing of the train door 11. The comparison unit is used to receive the image initially captured by the camera 2. The calculation unit controls the operation of the first driver 5;

[0059] Specifically, the processing module includes the following operation steps:

[0060] S1. When the train 3 stops at the platform 1, the distance between the train 3 and the platform 1 is detected in real time through the distance sensor 7, and the signal is transmitted to the calculation unit;

[0061] S2. Set the constant distance between the train 3 and the platform 1 as m, which is the appropriate distance between the train 3 and the platform 1;

[0062] S3. When the distance sensor 7 detects that the distance between the train 3 and the platform 1 is less than or equal to m, it means that the gap between the train 3 and the platform 1 is in an adaptive state;

[0063] S4. When the distance sensor 7 detects that the distance between the train 3 and the platform 1 is greater than m, it indicates that the gap between the train 3 and the platform 1 has widened. At this time, the calculation unit transmits a signal to the first drive 5 to control the first drive 5 to extend, driving the connecting plate 6 to extend out of the sliding groove 8, shortening the gap, which can achieve a protective effect in advance, prevent the legs and feet of passengers from getting stuck in the gap when getting on and off the train, and improve safety;

[0064] Embodiment 2

[0065] Please refer to Figures 1-3 , on the basis of Embodiment 1, in this embodiment, the following structure is added:

[0066] The alarm module includes an obstacle recognition sub-module, a deviation analysis unit, and a warning sub-module, where:

[0067] The obstacle recognition sub-module is electrically connected to the image storage unit, and the deviation analysis unit is electrically connected to the image storage unit;

[0068] The obstacle recognition sub-module includes a judgment unit, and the judgment unit is electrically connected to the infrared irradiator;

[0069] The alarm module includes the following operation steps:

[0070] A1. Before the train 3 starts for the first time, the camera 2 takes a photo of the gap between the train 3 and the station 1, which is photo A, and transmits it to the comparison unit as a comparison photo for subsequent comparison work;

[0071] A2. When the train 3 stops at the platform 1, the camera 2 takes a real-time photo of the gap and transmits it to the image storage unit, which is photo B;

[0072] A3. In the processing module, photo B and photo A are compared, and a signal is transmitted to the obstacle recognition sub-module. And the size of the obstacle is judged by the judgment unit, and the danger coefficient of the obstacle is judged; Since photo A is the photo taken when the train first travels, there is no obstacle in the photo of the train 3 and the platform 1. Therefore, when comparing, if there is an obstacle in photo B, there will be an error when matching with photo A. Therefore, the obstacle recognition sub-module will judge the existence of the obstacle;

[0073] A4. The image storage unit transmits the signal to the deviation analysis unit to judge the position of the camera 2;

[0074] Specifically, A3 includes the following specific operation steps:

[0075] A31. When the obstacle recognition sub-module recognizes that there is no obstacle at the gap, when the train 3 stops, the opening and closing unit normally controls the opening and closing of the train door 11 to facilitate passengers to get on and off normally;

[0076] A32. When the obstacle recognition sub-module recognizes an obstacle at the gap but the infrared irradiator is not blocked, it indicates that the obstacle is small, the risk coefficient is low, not higher than Platform 1, and it will not affect passengers' entry and exit. Repeat step A31;

[0077] A33. When there is an obstacle at the gap and the infrared irradiator is blocked, at this time the infrared irradiator transmits a signal to the judgment unit, indicating that the obstacle is large, the risk coefficient is high, it will affect the operation of the protection component, and it will also affect passengers' entry and exit of Train 3. The judgment unit transmits the signal to the opening and closing unit to make the opening and closing unit control the suspension of the opening of Train Door 11 to ensure the safety of passengers in advance;

[0078] A34. The judgment unit then transmits the signal to the warning sub-module to remind the staff that there is an obstacle at the gap of Train 3 affecting passengers' entry and exit, and the staff will clean up the obstacle;

[0079] Embodiment III

[0080] Please refer to Figures 1-3 , on the basis of Embodiment 2, in this embodiment, the following structure is added:

[0081] A4 includes the following specific operation steps:

[0082] A41. The deviation analysis unit receives the signal of Photo A in the comparison unit and records in advance the shooting angle of Camera 2 as a before Train 3 travels;

[0083] A42. The image storage unit then transmits Photo B to the deviation analysis unit for analyzing the shooting angle as b. Thus, the deviation analysis unit compares b with a to judge the shooting angle of Camera 2. When b is equal to a, it indicates that Camera 2 is not affected by the vibration during the travel of Train 3 and can continue shooting. When b is not equal to a, it indicates that Camera 2 is affected by the vibration generated during the travel of Train 3 and the shooting angle has changed. At this time, a signal is transmitted to the warning sub-module to inform the staff for easy maintenance, thereby improving the accuracy of detecting obstacles and reducing the false alarm rate;

[0084] The warning sub-module includes a broadcasting unit;

[0085] Since the number of Train Doors 11 is large and Camera 2 corresponds to Train Door 11, in the monitoring system, a one-to-one serial number is formed between Camera 2 and Train Door 11. When one or several cameras detect an obstacle or the angle deviates, the serial numbers of Camera 2 and Train Door 11 are informed to the staff through the warning sub-module for easy positioning, and the serial number of the dangerous train door is told to the passengers through the broadcasting unit so that the passengers can avoid the dangerous train door.
