Description

Technical Field

[0001] The present invention relates to the technical field of railway safety protection, and in particular to a railway safety protection system and method. Background Art

[0002] With the rapid development of railway transportation, the railway network is becoming more and more dense, and the number of railway platforms is also increasing. The safety of passengers on the platforms is receiving increasing attention. If passengers fall into the track area due to improper standing position or accidental fall while waiting for the train on the platform, it will pose a serious threat to the safety of passengers' lives and property, and the normal operation of the train will also be affected.

[0003] At present, most railway platforms have set up yellow lines as safety warning lines, and train controllers manually supervise the waiting passengers on the platform. However, this method can only serve as a basic reminder and has limited effect in preventing passengers from accidentally falling. It also brings a huge workload to platform managers.

[0004] The development of a more intelligent and automated platform safety protection system has become an important demand. The existing railway safety protection system does not have the function of personalized lifting and lowering according to the actual platform conditions. Therefore, in order to better adapt to the needs of railway platform safety protection and passengers, a system and method is needed that can improve the efficiency of passengers riding on the platform while ensuring platform safety. Summary of the invention

[0005] The invention provides a railway safety protection system and method.

[0006] The technical solution of the present invention is as follows:

[0007] A railway safety protection system, comprising:

[0008] Rope lifting module: driven by the driving module, several groups of ropes move up or down in sequence along the vertical guide rails on two adjacent columns until several groups of ropes move up to the set highest point and overlap, or several groups of ropes are arranged in sequence from top to bottom at the preset position to form a rope safety door;

[0009] Driving module: receiving instructions from the control module or manual operation module to drive the rope lifting module. It is also used to receive instructions from the control module in the event of a power outage to lock the position of the rope during movement.

[0010] Monitoring module: used to monitor the tension of several groups of ropes and obtain rope tension data; used to monitor the density of people on the platform and obtain people density data; used to monitor whether there are people under the ropes and obtain human activity data; used to monitor the number, speed, parking position, arrival time and departure time of the arriving train and obtain the information of the arriving train; used to monitor the distance between the waiting passengers and the ropes and the height information of the waiting passengers and obtain the distance data and height data.

[0011] The obtained tension data, crowd density data, human activity data, arrival train information, distance data and height data are sent to the control module;

[0012] Manual operation module: including a button arranged on the column and electrically connected to the driving module, used to send instructions to the driving module to drive the rope lifting module to move the rope up or down;

[0013] Alarm module: used to receive signals from the control module and make sound and light alarms;

[0014] Display module: used to display the train number, type, departure time, arrival time, travel direction, and number of carriages of the arriving train in real time;

[0015] Mobile positioning module: used by platform staff to wear, obtain the staff's position and movement direction in real time, and transmit the position and movement direction information to the control module;

[0016] The control module obtains the position and movement direction of the platform staff in real time in the first time period before the train leaves or arrives, and determines whether the platform staff can reach the key position of the manual operation module at the time of train departure or arrival:

[0017] If the platform staff cannot reach the button position within the second time period before the train arrives, the control module sends a command to the drive module to drive the rope lifting module to move at the train arrival time, so that several groups of ropes rise to the set highest position in sequence;

[0018] If the platform staff cannot reach the button position within the second time period before the train leaves, the control module sends a command to the drive module to drive the rope lifting module to operate at the time of train departure, so that the ropes are sequentially lowered to the set lowest position.

[0019] Specifically, the rope lifting module includes several columns and several groups of ropes arranged between two adjacent columns. The several groups of ropes are moved up and down by vertical guide rails arranged on two adjacent columns. Every two adjacent columns and the several groups of ropes therebetween constitute a liftable rope safety door.

[0020] Furthermore, the control module also includes

[0021] During the waiting stage:

[0022] If the monitoring module detects that the horizontal distance between the waiting passenger and the rope is less than the first warning distance, and the height of the waiting passenger is within the first height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module. The control module controls the alarm module to start a first-level alarm, the alarm horn prompts, and the LED alarm light flashes red;

[0023] If the monitoring module detects that the horizontal distance between the waiting passenger and the rope is less than the second warning distance, and the height of the waiting passenger is within the second height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module. The control module controls the alarm module to start the secondary alarm, the alarm horn prompts, and the LED alarm light flashes yellow;

[0024] If the monitoring module detects that the horizontal distance between the waiting passenger and the rope is less than the third warning distance, and the height of the waiting passenger is within the third height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module. The control module controls the alarm module to start the third-level alarm, the alarm horn prompts, and the LED alarm light flashes blue light;

[0025] During the ride:

[0026] At the time of train arrival, if the monitoring module detects that there is no human activity under the rope and in the warning area, the real-time monitored crowd density data will be sent to the control module, and the control module will send a signal to the drive module to control the rising speed of the rope in the rope lifting module:

[0027] If the crowd density is less than the first threshold, the control rope is raised at the first lifting speed, which is the standard speed;

[0028] If the first threshold value ≤ the crowd density < the second threshold value, the control rope is raised at the second lifting speed;

[0029] If the second threshold value ≤ the crowd density < the third threshold value, the control rope is raised at the third lifting speed;

[0030] Wherein, the first threshold value < the second threshold value < the third threshold value, corresponding to the first lifting speed < the second lifting speed < the third lifting speed;

[0031] During the train departure phase:

[0032] When the train leaves, a control signal is sent to the driving module, and the driving module drives the rope lifting module to complete the sequential descent of several groups of ropes until each group of ropes reaches a preset position.

[0033] Specifically, the monitoring module uses a tension sensor to monitor the tension of several groups of ropes; uses a camera to take real-time photos of the waiting area of ​​the platform, counts the passengers in the image, and ratios the count value with the area of ​​the photographed waiting area to obtain crowd density data; uses an infrared sensor to monitor whether there is human activity under the rope; uses a vehicle identification sensor to monitor the train number, speed and parking position of the arriving train; and uses a laser ranging sensor to measure the distance between the waiting passengers and the rope and the height information of the waiting passengers.

[0034] Furthermore, the tension sensors are used to monitor the tension of several groups of ropes:

[0035] If the obtained tension data drops to the set first tension standard threshold within a specific time, it is determined that the rope is broken, and a signal is sent to the alarm module to trigger an alarm;

[0036] If the difference between the tension data measured by the tension sensors connected to both sides of the rope is greater than the set second tension standard threshold, it is determined that the lifting and lowering of both sides of the rope are unbalanced, and a signal is sent to the alarm module to trigger an alarm;

[0037] At the same time, a signal is sent to the driving module to raise several groups of ropes to the highest point.

[0038] Furthermore, the infrared sensor is used to monitor whether there is human activity under the rope:

[0039] If there is any movement under the rope, a signal is sent to the control module to shut down the drive module until no movement is detected under the rope, at which point the drive module is turned on to lower the rope.

[0040] Specifically, the tension sensor is arranged inside the column, and is consistent with the number of groups of ropes arranged on the column and is connected one-to-one; the camera is arranged above the column, and its angle is adjusted so that its monitoring range covers the area of ​​the designated waiting area; the infrared sensor is arranged under the rope; the vehicle identification sensor is arranged on the column and is located on the side facing the train; the laser ranging sensors are respectively arranged on the side of the column facing the waiting area and above the waiting area.

[0041] Furthermore, it also includes a reconnection protection module: used to receive instructions from the control module. At the arrival time of the train, the servos arranged on the two columns corresponding to the reconnection part of the train facing the side of the train execute the lowering action, perform side protection, and form a closed safety area with the rope safety door arranged facing the waiting area.

[0042] Specifically, the driving module includes a motor and a conveyor belt connected to an output end of the motor, and the conveyor belt drives a plurality of groups of ropes to move up and down along a vertical guide rail.

[0043] Preferably, the alarm module includes an alarm speaker arranged inside the column and an alarm light arranged above the column.

[0044] The beneficial effects of the present invention are:

[0045] 1. The present invention sets a warning distance according to the height data of the waiting passengers closest to the ropes monitored in real time, ensuring that the waiting passengers are in a safe area. At the same time, the rising speed of several groups of ropes is controlled according to the real-time crowd density, and several groups of ropes are raised and lowered in a personalized and intelligent manner, which can not only improve the passenger's riding efficiency while ensuring the safety of passengers, but also reduce the workload of platform managers.

[0046] 2. The reconnection protection module and the rope lifting module cooperate with each other to form a closed safety area during the train entry and exit and reconnection operation, effectively protecting the safety of passengers and staff; manual operation and automatic control complement each other, and the lifting and lowering of several groups of ropes are intelligently and automatically controlled to ensure the reliability of the railway safety protection system.

[0047] 3. Through real-time monitoring and automatic control, the system can respond promptly to situations such as rope breakage, imbalance in lifting and lowering on both sides, and human activities under the rope, and issue alarms in a timely manner to reduce the risk of accidents.

[0055] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0056] Example

[0057] This embodiment provides a railway safety protection system. Figure 1 , Figure 2 and Figure 3 ,include:

[0058] Rope lifting module: used for, under the drive of the driving module, several groups of ropes 2 move up or down in sequence along the vertical guide rails on two adjacent columns 1, until several groups of ropes 2 move up to the set highest position and overlap, or several groups of ropes 2 are arranged in sequence from top to bottom at the preset position, forming a rope safety door;

[0059] Driving module: used to drive the rope lifting module under the command of the control module, and also used to receive the command of the control module in the case of power failure, to lock the position of the rope 2 during the movement, and to prevent the rope 2 from falling under the action of gravity;

[0060] Monitoring module: used to monitor the tension of several groups of ropes 2 and obtain rope 2 tension data; used to monitor the density of people on the platform and obtain people density data; used to monitor whether there are people under the ropes 2 and obtain human activity data; used to monitor the number, speed and parking position of the arriving train and obtain the information of the arriving train; used to monitor the distance between the waiting passengers and the ropes 2 and the height information of the waiting passengers and obtain the distance data and height data.

[0067] Control module: used to receive data from the rope lifting module, drive module, monitoring module, manual operation module, alarm module and display module in real time, generate control instructions and send them to each module.

[0068] The control module obtains the staff's position and moving direction in real time in the first time period before the train leaves or arrives, and determines whether the staff can reach the button position of the manual operation module when the train leaves or arrives: the judgment here is estimated by the distance between the staff and the button position / the staff's real-time moving speed.

[0069] If the button position cannot be reached within the second time period before the train arrives, the control module sends a command to the drive module to drive the rope lifting module to move at the train arrival time, so that several groups of ropes 2 are lowered in sequence to form a rope safety door;

[0070] If the key position cannot be reached within the second time period after the train leaves, the control module sends a command to the drive module to drive the rope lifting module to operate so that the ropes 2 are successively raised to the set highest point.

[0071] In the present invention, the mobile positioning module uses a Beidou positioning chip, the first time period is set to 30 seconds, and the second time period is set to 5 seconds.

[0072] Specifically, in this embodiment, the control module is used to receive data from the rope lifting module, driving module, monitoring module, manual operation module, alarm module and display module in real time, generate control instructions and send them to each module. At the same time, the control module can obtain the train number, type, departure time, arrival time, travel direction, and number of carriages of the arriving train published by the DMIS system in real time, and transmit the obtained information to the display module.

[0073] The control module also includes setting different warning distances based on different heights. The first height range is height ≤ 1.2m, corresponding to the first warning distance of 1.5m; the second height range is 1.2m < height ≤ 1.5m, corresponding to the second warning distance of 1m; the third height range is height > 1.5m, corresponding to the third warning distance of 0.5m.

[0074] In the waiting stage: if the monitoring module detects that the horizontal distance between the waiting passenger and the rope 2 is less than the first warning distance, and the height of the waiting passenger is within the first height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module. The control module controls the alarm module to start a first-level alarm, the alarm horn prompts, and the LED alarm light 7 flashes red;

[0075] If the monitoring module detects that the horizontal distance between the waiting passenger and the rope 2 is less than the second warning distance, and the height of the waiting passenger is within the second height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module.

[0076] If the monitoring module detects that the horizontal distance between the waiting passenger and the rope 2 is less than the third warning distance, and the height of the waiting passenger is within the third height range, it is determined that the passenger has entered the warning area, and a signal is sent to the control module. The control module controls the alarm module to start the third-level alarm, the alarm horn prompts, and the LED alarm light 7 flashes blue light;

[0077] During the boarding stage: When the train arrives, if the monitoring module detects that there is no human activity under the rope 2 and in the warning area, the real-time monitored crowd density data is sent to the control module, and the control module sends a signal to the drive module to control the rising speed of the rope 2 in the rope lifting module:

[0078] If the crowd density is less than the first threshold, the rope 2 is controlled to rise at the first lifting speed, which is the standard speed;

[0079] If the first threshold value ≤ the crowd density < the second threshold value, the rope 2 is controlled to rise at the second lifting speed;

[0080] If the second threshold value ≤ the crowd density < the third threshold value, the rope 2 is controlled to rise at the third lifting speed;

[0081] Wherein, the first threshold value < the second threshold value < the third threshold value, corresponding to the first lifting speed < the second lifting speed < the third lifting speed;

[0082] During the train departure phase:

[0083] When the train leaves, a control signal is sent to the driving module, and the driving module drives the rope lifting module to complete the sequential descent of several groups of ropes 2 until each group of ropes 2 reaches a preset position.

The control module obtains the staff's position and moving direction in real time within 30 seconds before the train leaves or arrives, and determines whether the staff can reach the key position of the manual operation module at the time of train departure or arrival:

[0085] If the button position cannot be reached within 5 seconds before the train arrives, the control module sends a command to the drive module to drive the rope lifting module to move at the train arrival time, so that several groups of ropes 2 are lowered in sequence to form a rope safety door;

[0086] If the key position cannot be reached within 5 seconds after the train leaves, the control module sends a command to the drive module to drive the rope lifting module to operate so that the ropes 2 are successively raised to the set highest point.

[0087] When actually used on the platform, the manual operation mode is preferred, that is, by manually pressing the button on the column 1, a command is sent to the drive module to drive the rope 2 up or down. By combining manual operation and automatic control, the railway platform safety protection system can fully cope with various operating situations and ensure the safety of passengers and staff.

[0088] In the present invention, the rope lifting module includes a plurality of columns 1 and a plurality of groups of ropes 2 arranged between two adjacent columns 1. The plurality of groups of ropes 2 are moved up and down by vertical guide rails arranged on two adjacent columns 1. Each two adjacent columns 1 and the plurality of groups of ropes 2 therebetween constitute a liftable rope safety door. In this embodiment, three groups of movable ropes 2 are arranged between each two adjacent columns 1, and the number of movable ropes 2 in each group is 4.

[0093] If the obtained tension data drops to the set first tension standard threshold within a specific time, it is determined that the rope 2 is broken, and a signal is sent to the alarm module to trigger an alarm;

[0094] If the difference between the tension data respectively measured by the tension sensors 8 connected to both sides of the rope 2 is greater than the set second tension standard threshold, it is determined that the lifting and lowering of both sides of the rope 2 is unbalanced, and a signal is sent to the alarm module to trigger an alarm;

[0095] At the same time, a signal is sent to the driving module to raise several groups of ropes 2 to the highest point, and the staff further inspects the ropes 2.

[0096] At the same time, in this embodiment, an infrared sensor is used to monitor whether there is human activity under the rope 2:

[0097] If there is any movement under the rope 2, a signal is sent to the control module to turn off the drive module, until no movement is detected under the rope 2, the drive module is turned on to lower the rope 2.

[0098] The manual operation module includes a button arranged on the column 1 and electrically connected to the driving module, and is used to send instructions to the driving module to drive the rope lifting module to move and make the rope 2 rise or fall.

[0099] The present invention also includes a reconnection protection module, which is used to receive instructions from the control module. At the arrival time of the train, the servos 5 arranged on the two columns corresponding to the reconnection part of the train facing the side of the train execute a lowering action, driving the railing connected to the servo 5 to rotate from a vertical downward position to a horizontal position, performing side protection, and forming a closed safety area with the rope safety door arranged facing the waiting area.
