[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0045] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0046] like Figure 1-Figure 2 As shown, the present invention provides a method for automatically raising and lowering a safety guardrail, including:

[0047] The main controller 6 is used to control the lifting and lowering of the safety guardrails on all platforms 7 and display their real-time status;

[0048] A sub-controller 4 is provided on each platform 7 and is in communication with the main controller 6; the sub-controller 4 is used to control the safety guardrail on the platform 7 and collect status data;

[0049] The remote controller 3 is in communication with the sub-controller 4 ; the remote controller 3 is used to control the raising and lowering of the safety guardrail on the platform 7 .

[0050] On both sides of the platform 7 are usually tracks 8 for trains to pass. In the prior art, when there is no train on the track 8, there is no isolation measure on the side of the platform 7 close to the track 8, which poses a safety hazard.

[0051] A safety guardrail is provided on each platform 7 near the track 8. The raising and lowering of the safety guardrail can open or release the isolation state between the platform 7 and the track 8. The raising and lowering of the safety guardrail is controlled by each sub-controller 4. The sub-controller 4 can also collect the status data of the safety guardrail. The main controller 6 and the remote controller 3 both control the safety guardrail through the sub-controller 4.

[0052] The master controller 6 can be set in the dispatching room and connected to the sub-controller 4 on each platform 7. It is used to control the safety guardrails on multiple platforms 7 and can display the status of the safety guardrails on each platform 7 in real time.

[0053] The remote controller 3 is operated by the staff of each station 7 to control the raising and lowering of the safety guardrail according to the actual situation.

[0054] Through the above control method, when there is no train on the track 8, the safety guardrail on the platform 7 can be controlled in a variety of ways to automatically switch to an isolated state, so that the track 8 and the platform 7 are automatically isolated, minimizing safety hazards; and after a train comes on the track 8, the safety guardrail can be controlled in a variety of ways to automatically switch to a released isolation state. At this time, the track 8 and the platform 7 are released and will not hinder boarding and alighting; the main controller 6 can perform unified status monitoring of the safety guardrails on all platforms 7, realize automated unified management, assist staff in maintaining order, and reduce safety hazards.

[0055] like Figure 3 As shown, in one embodiment, the platform 7 is provided with a plurality of sensors 9 in communication with the sub-controller 4 on the side close to the track 8, and the sensors 9 are used to collect train information on the track 8;

[0056] When multiple sensors 9 all detect that there is a train on the track 8, the sub-controller 4 controls the safety guardrail to switch to the released isolation state;

[0057] When at least one of the multiple sensors 9 detects that there is no train on the track 8, the sub-controller 4 controls the safety guardrail to switch to the isolation state.

[0058] The sensor 9 is used to identify the presence of a train on the track 8. A plurality of sensors 9 are provided on the track 8.

[0059] When a train enters the station, multiple sensors 9 will collect train information in sequence and transmit the train information to the sub-controller 4. When all sensors 9 have collected train information, the sub-controller 4 will receive the train information transmitted by all sensors 9. Then, the sub-controller 4 will delay for a preset time and then control the safety guardrail to automatically switch to the released isolation state to ensure that the train has completely entered the station, so that passengers can get on and off the train.

[0060] When a train leaves the station, multiple sensors 9 will collect information about no train in turn and pass the information about no train to the sub-controller 4. As long as one sensor 9 detects that there is no train information, the sub-controller 4 will receive the information about no train transmitted by this sensor 9, and the sub-controller 4 will control the safety guardrail to switch to an isolated state, isolating the track 8 and the platform 7 to improve safety.

[0061] In one embodiment, when the sub-controller 4 controls the safety guardrail according to train information, if the remote controller 3 or the main controller 6 sends a control signal to the sub-controller 4, the sub-controller 4 will give priority to executing the control signal sent by the remote controller 3 or the main controller 6.

[0062] The process in which the sub-controller 4 controls the safety guardrail based on the train information refers to the process in which the sub-controller 4 controls the safety guardrail based on the train conditions detected by the sensor 9. During this process, if the remote control 3 or the main controller 6 sends a control signal, the sub-controller 4 will give priority to executing the control signal of the remote control 3 or the main controller 6; this is because the remote control 3 and the main controller 6 are operated by relevant staff who are familiar with the actual situation on site, so the safety guardrail will be controlled by the remote control 3 and the main controller 6 first to further improve the protection safety.

[0063] In one embodiment, the safety guardrail includes: multiple guardrail units, each guardrail unit is communicatively connected to the sub-controller 4; the sub-controller 4 and the remote control 3 can both control the action of each guardrail unit individually, or control the action of multiple guardrail units simultaneously.

[0064] The safety guardrail on each platform 7 can be composed of a plurality of guardrail units arranged in sequence, and each guardrail unit can be provided with a number. The sub-controller 4 and the remote controller 3 are provided with individual control keys corresponding to the numbers for individually controlling each guardrail unit, as well as a master control key for controlling the simultaneous operation of multiple guardrail units. In this way, the sub-controller 4 and the remote controller 3 can control the operation of the guardrail units individually or simultaneously.

[0065] In this way, if one guardrail unit fails, the remaining guardrail units can also be raised and lowered without affecting use.

[0066] In one embodiment, each guardrail unit is provided with a control button that is in communication with the sub-controller 4;

[0067] The control button is provided with an audible and visual alarm, which is used to emit audible and visual warning information when the safety guardrail switches between states.

[0068] The control button on each guardrail unit can realize the lifting and lowering of all guardrail units or the lifting and lowering of a certain guardrail unit. An audible and visual alarm can be set on the control button. When the guardrail unit is raised or lowered, there will be an audible and visual alarm to alert nearby people.

[0069] In one embodiment, the state data collected by the sub-controller 4 on the safety guardrail includes: isolation state, isolation release state and abnormal state;

[0070] When the sub-controller 4 detects that at least one guardrail unit is in an abnormal state, the guardrail unit in the abnormal state stops continuing to operate, an alarm is issued, and the abnormal state information is transmitted to the main controller 6 through the cloud server 5;

[0071] After the abnormal state is resolved, the alarm prompt is cancelled through the sub-controller 4 or the main controller 6.

[0072] The sub-controller 4 can obtain the status data of each guardrail unit in real time, and the obtained status data will be transmitted to the main controller 6 for display in real time. In this way, if an abnormality occurs in the guardrail unit, for example, the guardrail unit fails to complete the switching state action, or when the guardrail unit is in action, there is an obstacle that prevents the guardrail unit from continuing to move, then the sub-controller 4 can receive the abnormal status information, and the sub-controller 4 will control the corresponding guardrail unit to stop continuing to move, and at the same time issue an alarm prompt to prompt the on-site staff to come forward to check, so as to reduce the occurrence of accidents. At the same time, the sub-controller 4 will also transmit the abnormal status information to the main controller 6 through the cloud server 5, and the staff of the main dispatching room can also be informed of the abnormal status information of this guardrail unit. The on-site staff and the staff of the main dispatching room can both judge the abnormal status according to the actual situation. When it is determined that the abnormal status is lifted, the alarm prompt can be lifted through the sub-controller 4 or the main controller 6;

[0073] In this way, by collecting the status data of the guardrail unit and providing alarm prompts for abnormal conditions, on-site staff can be assisted in maintaining order on the platform, and staff can be reminded in time of abnormal situations, thereby minimizing safety hazards.

[0074] like Figure 4 As shown, in one embodiment, the guardrail unit includes: at least two lifting columns 1, with multiple vertically distributed safety belts 2 provided between the two lifting columns 1; when the lifting columns 1 perform a first action to deploy the multiple safety belts 2, the safety guardrail is in an isolated state; when the lifting columns 1 perform a second action to retract the multiple safety belts 2, the safety guardrail is in a released isolation state.

[0075] The guardrail unit includes at least two lifting columns 1, and safety belts 2 are connected to two adjacent lifting columns 1. Multiple safety belts 2 are evenly distributed along the lifting direction of the lifting columns 1. At least two lifting columns 1 of a guardrail unit act simultaneously, that is, they rise or fall at the same time; when the lifting columns 1 perform a first action, multiple safety belts 2 will be deployed to form a guardrail in the space area between the two lifting columns 1, isolating the track 8 and the platform 7; when the lifting columns 1 perform a second action, multiple safety belts 2 will be retracted, the space area between the two lifting columns 1 will be opened, and the track 8 and the platform 7 will be released. The action of the lifting columns 1 is controlled by the sub-controller 4, the remote control 3, the main controller 6 and the control buttons to achieve automatic lifting.

[0076] like Figure 4-Figure 8 As shown, in one embodiment, the lifting column 1 comprises:

[0077] The bottom column 110 is provided on the platform 7; a support frame 120 is provided inside the bottom column 110;

[0078] The telescopic column 130 is slidably disposed in the base column 110;

[0079] The first diamond-shaped telescopic frame 140 is disposed in the base column 110 and has its bottom end hinged to the support frame 120 via a first connecting shaft 160;

[0080] The second diamond-shaped telescopic frame 150 is disposed within the telescopic column 130, and its top end is hinged to the top end of the telescopic column 130 via a second connecting shaft 170; the end of the safety belt 2 is connected to the hinge point in the middle of the second diamond-shaped telescopic frame 150;

[0081] The top end of the first diamond-shaped telescopic frame 140 is connected to any hinge point in the middle of the second diamond-shaped telescopic frame 150 via a third connecting shaft 180; wherein any hinge point is any hinge point located below the second connecting shaft 170;

[0082] The third connecting shaft 180 is preferably located at the first hinge point below the second connecting shaft 170;

[0083] The driving unit is in communication with the sub-controller 4 and is used to drive the first diamond-shaped telescopic frame 140 to move.

[0084] The driving part can be hydraulically driven, pneumatically driven or electrically driven to control the first diamond-shaped telescopic frame 140 to perform telescopic movements. The operation of the driving part is controlled by the sub-controller 4, the remote controller 3, the main controller 6 and the control buttons;

[0085] like Figure 4 As shown, when the lifting column 1 is in the retracted state, the first diamond-shaped telescopic frame 140 is in the retracted state, and the second diamond-shaped telescopic frame 150 is in the extended state, the multiple safety belts 2 connected to the second diamond-shaped telescopic frame 150 are in the deployed state, and the multiple safety belts 2 are spaced a certain distance apart, forming a guardrail in the space between the two lifting columns 1;

[0086] like Figure 5 As shown, when the driving unit executes the control command to release the isolation state, the lifting column 1 switches to the extended state, the second diamond-shaped telescopic frame 150 is retracted upward as a whole, and the multiple safety belts 2 connected thereto also move upward. At the same time, the third connecting shaft 180 moves upward, driving the top end of the first diamond-shaped telescopic frame 140 to move upward and extend as a whole, and the telescopic column 130 is lifted. When the second diamond-shaped telescopic frame 150 is fully retracted, all the safety belts 2 are located at the top end of the telescopic column 130, and the space between the two lifting columns 1 can allow people to pass through;

[0087] In the above structure, the structural characteristics of the first diamond-shaped telescopic frame 140 and the second diamond-shaped telescopic frame 150 are utilized. As long as the two adjacent hinge points in the middle of the diamond-shaped telescopic frame are driven closer to or away from each other, the entire diamond-shaped telescopic frame can be driven to extend and retract, so that the movement of the driving part is small and the diamond-shaped telescopic frame has good support. In addition, the top end of the first diamond-shaped telescopic frame 140 is connected to the second diamond-shaped telescopic frame 150 through the third connecting shaft 180, and the bottom end is connected to the support frame 120 through the first connecting shaft 160, so that the first diamond-shaped telescopic frame 140 and the second diamond-shaped telescopic frame 150 can move at the same time. When one extends, the other will retract, thereby realizing the switching of the isolation state and the release state of the safety guardrail by the safety belt 2 as the telescopic column 130 rises and falls, and the structure is simple.

[0088] like Figure 9-10 As shown, further, the end of the safety belt 2 is connected to the hinge point in the middle of the second diamond-shaped telescopic frame 150, and each hinge point is provided with a hinge shaft 151. The second connecting shaft 170 and the third connecting shaft 180 are both included in the multiple hinge shafts 151. The hinge shaft 151 is outer-circuited with a connecting tube 152, and both ends of the connecting tube 152 are provided with limiting ring plates 153. An annular groove 154 is formed between the two limiting ring plates 153, and the end of the safety belt 2 is provided with a connecting hole 210 that is sleeved with the annular groove 154; the opposite side of the two limiting ring plates 153 and the surface of the annular groove 154 are provided with pressure sensors that are in contact with the safety belt 2. When the pressure value detected by at least one pressure sensor is greater than the corresponding preset pressure value, an abnormal status information is sent to the sub-controller 4.

[0089] like Figure 11-12 As shown, specifically, the connecting cylinder 152 is rotatably connected to the hinge shaft 151, and the hinge shaft 151 may be provided with a structure for limiting the axial movement of the connecting cylinder 152, such as a pin or a limiting ring.

[0090] The safety belt 2 is made of a soft and elastic material;

[0091] The safety belt 2 is sleeved on the outer side of the annular groove 154 through the connection hole 210 provided at its end. The portion of the end of the safety belt 2 that contacts the pressure sensor can exert a squeezing force on the pressure sensor, thereby sensing whether the safety belt 2 encounters resistance when retracting or deploying, and whether the safety belt 2 is subjected to external force when stationary.

[0092] For example, when the seat belt 2 is being retracted or extended, if it hits a passenger or other object, causing resistance to its movement, the seat belt 2 will deform due to the resistance, thereby generating tension at both ends of the seat belt 2. This force will act on the pressure sensors provided on the surface of the annular groove 154. Alternatively, if someone wants to cross the seat belt 2 when the seat belt 2 is stationary, since the gap between two adjacent seat belts 2 is small, the crossing will inevitably cause a pull on the seat belt 2. Both ends of the seat belt will also be pulled, and the pressure sensors located on the limiting ring plate 153 or the annular groove 154 will sense the change in pressure value.

[0093] When at least one of the pressure sensors detects a pressure value greater than a reference pressure value (pre-set reference pressure value), an abnormal state information is sent to the sub-controller 4, an alarm is issued, and the abnormal state information is transmitted to the main controller 6 through the cloud server 5. If the guardrail unit is in operation, the guardrail unit in the abnormal state will be immediately stopped from continuing to operate;

[0094] By sensing the pressure of the safety belt 2, it is possible to detect whether the guardrail unit is in an abnormal state and to give an alarm in time to prompt the staff to check the abnormal situation on site in time and reduce safety hazards as much as possible.

[0095] In one embodiment, the output end of the driving unit is connected to any one connecting shaft in the middle of the first diamond-shaped telescopic frame 140 ; ​​wherein, any one connecting shaft is any one connecting shaft located above the first connecting shaft 160 .

[0096] The driving part may be arranged on the inner top of the telescopic column 130 or on the support frame 120;

[0097] When arranged on the top of the telescopic column 130, the output end of the driving unit is preferably connected to the topmost connecting shaft of the first diamond-shaped telescopic frame 140, that is, the third connecting shaft 180 connected to the second diamond-shaped telescopic frame 150. The output end of the driving unit can be snap-connected or fixedly connected to the extended portion of the third connecting shaft 180. The up and down movement of the third connecting shaft 180 can simultaneously drive the first diamond-shaped telescopic frame 140 and the second diamond-shaped telescopic frame 150 to move.

[0098] When set on the support frame 120, the output end of the driving unit is preferably connected to the first connecting shaft on the second diamond-shaped telescopic frame 140 located above the first connecting shaft 160, that is, the connecting shaft adjacent to the first connecting shaft 160. The up and down movement of the third connecting shaft 180 can simultaneously drive the first diamond-shaped telescopic frame 140 and the second diamond-shaped telescopic frame 150 to move.

[0099] In one embodiment, at least one side of the base column 110 is provided with a first slot, which extends vertically through the top of the base column 110; at least one side of the telescopic column 130 is provided with a second slot corresponding to the first slot, which extends vertically through the bottom end of the telescopic column 130; the first slot and the second slot are for the safety belt 2 to pass through.

[0100] In order to facilitate the up and down movement of the safety belt 2, at least one side of the bottom column 110 and the telescopic column 130 is respectively provided with a first notch and a second notch, so that the safety belt 2 can pass through.

[0101] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
