Description

Technical Field

[0001] The utility model relates to the technical field of platform safety monitoring, in particular to a platform safety monitoring system. Background Art

[0002] With the development of society and the continuous improvement of high-speed rail technology, more and more people choose rail transit for travel. When taking a high-speed rail or train, passengers often need to enter the platform in advance to wait for the train to arrive at some train stations because the train stops for a short time. At present, the platforms of train stations are open, and passengers often approach the edge of the platform to grab a seat or observe the train situation, which may bring a series of safety problems. At present, the railway station draws a yellow warning line on the ground at the edge of the platform, but this prevention method is passive and requires supervision and management by platform staff. It is time-consuming and labor-intensive, and it is very inconvenient and cannot detect and stop dangerous behaviors in time.

[0003] In addition, the marks corresponding to the car numbers are drawn on the ground at the edge of the platform, and passengers need to get close to see them clearly, which increases safety risks. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a platform safety monitoring system.

[0005] The technical solution of this utility model is as follows:

[0006] A platform safety monitoring system, comprising:

[0007] The central control platform is set up in the railway station;

[0008] The guardrail mechanism includes a plurality of lifting columns arranged at intervals along the edge of the platform, wherein a movable part and a driving device for driving the movable part to move vertically are arranged in the lifting columns, and a plurality of ropes are connected between adjacent lifting columns, and both ends of the ropes are connected to the movable part, and a tension sensor is arranged on the movable part;

[0009] The sensing unit is arranged at the lower part of the side wall of each lifting column to detect whether there is a person or object under the rope;

[0010] A video monitoring unit is installed on the top of each lifting column;

[0011] An alarm unit is arranged on each lifting column and is connected to the tension sensor, the sensing unit and the video monitoring unit by telecommunication;

[0012] The control unit is connected to the central control platform, each driving device, each tension sensor, each sensing unit, each video monitoring unit and each alarm unit by telecommunication.

[0013] Among them, the central control platform is connected to the travel service system of the rail transit to obtain various information of the train, such as real-time driving position, arrival time, etc., and control the operation of the barrier mechanism through the control unit according to the information.

[0014] In the above scheme, the lifting columns at both ends of the platform are also provided with end protection units for warning non-staff to leave. The end protection units preferably include image recognition sensors and voice announcers. When the approaching person is identified as a staff member, the end protection unit does not issue a warning.

[0015] Furthermore, the lifting columns at both ends of the platform are respectively provided with a vehicle entry detection sensor and a vehicle exit detection sensor, both of which are electronically connected to the control unit for detecting the entry and exit of the train, and then controlling the lifting and lowering of the rope according to the signal.

[0016] In addition, a gravity lifting structure is also provided inside the lifting column, including a pulley located at the top of the lifting column and a pull rope sliding on the pulley. One end of the pull rope is connected to the movable part, and the other end is connected to the gravity block. When a power outage occurs, the driving device loses its braking effect, and the movable part moves upward under the action of the gravity part, driving the rope to rise, releasing the blocking state, and ensuring that passengers can get on and off the platform normally when the power is off. A pull rope encoder is provided on one side of the pulley to obtain the rope elevation height in real time, which is electrically connected to the control unit.

[0017] Preferably, the sensing unit is an infrared sensor or an ultrasonic sensor.

[0019] In the present application, a display unit is provided at the front side of the lifting column, and the display unit includes a digital display and a display screen distributed up and down. The digital display shows the carriage number of the carriage corresponding to the lifting column, and the display screen shows the train arrival and departure information. Passengers can know the train information and carriage number from a distance without having to check close to the edge of the platform.

[0020] In addition, a projection unit is provided on the top of the lifting column, which is used to project the carriage number in front of the carriage door, so that passengers can quickly know the location of the carriage corresponding to their ticket, avoiding passengers from searching for the corresponding carriage along the edge of the platform.

[0021] In the present application, the safety monitoring system also includes a remote control unit, which is electrically connected to the control unit. Through the remote control unit, the barrier mechanism is remotely controlled to perform actions such as full opening, half opening, and reconnection switching, making it convenient for station staff to operate.

[0022] The utility model provides a platform safety monitoring system with the following beneficial effects:

[0023] 1. A blocking mechanism is provided to physically block passengers and prevent them from approaching the edge of the platform.

[0024] 2. Based on the guardrail mechanism, a tension sensor, a sensing unit, a video monitoring unit, an alarm unit and a control unit are equipped to timely detect and stop unsafe behaviors of passengers. In addition, the operation and stop of the guardrail mechanism can be flexibly controlled according to the detection information, which improves the safety of the use of the guardrail mechanism and provides effective safety monitoring and protection for platform passengers.

[0025] 3. Through the display unit and projection unit, the need for passengers to get close to the edge of the platform is reduced from the root, thereby improving the effectiveness of safety protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figures 1 to 5 As shown, the embodiment of the utility model provides a platform safety monitoring system, including:

[0035] The central control platform is set up in the railway station;

[0036] The guardrail mechanism comprises a plurality of lifting columns 1 arranged at intervals along the edge of the platform, wherein a movable part and a driving device for driving the movable part to move vertically are arranged in the lifting columns 1, and a plurality of ropes 2 are connected between adjacent lifting columns 1, and both ends of the ropes 2 are connected to the movable part, and a tension sensor 11 is arranged on the movable part;

[0037] The sensing unit 12 is arranged at the lower part of the side wall of each lifting column 1 to detect whether there is a person or object under the rope 2;

[0038] A video monitoring unit 13 is arranged on the top of each lifting column 1;

[0039] An alarm unit 14 is provided on each lifting column 1 and is electrically connected to the tension sensor 11, the sensing unit 12 and the video monitoring unit 13;

[0040] The control unit is connected to the central control platform, each driving device, each tension sensor 11 , each sensing unit 12 , each video monitoring unit 13 and each alarm unit 14 by telecommunication.

[0041] Among them, the central control platform is connected to the travel service system of the rail transit to obtain various information of the train, such as real-time driving position, arrival time, etc., and control the operation of the barrier mechanism through the control unit according to the information.

[0042] The rope 2 of the barrier mechanism moves downward to play a barrier role, and moves upward to allow passengers to pass.

[0043] The sensing unit 12 can be an infrared sensor or an ultrasonic sensor, which is used to detect whether there is a person or object under the rope 2, that is, whether there is a person or object between the two lifting columns 1. When a person or object is detected, the sensing unit 12 sends information to the control unit and the alarm unit 14. The alarm unit 14 is preferably an audible and visual alarm, which emits a warning sound and a warning light to remind people to leave or require people to move objects. The control unit controls the driving device to stop running, thereby fixing the position of the rope 2 to prevent the rope 2 from moving and scratching people or colliding with objects to damage the rope 2.

[0044] The video monitoring unit 13 may include at least one camera for real-time monitoring of the platform conditions, especially the lifting and lowering of the rope 2 and the situation of passengers approaching the rope 2. When the video monitoring unit 13 detects that the rope 2 is operating abnormally, it sends a signal to the alarm unit 14, and the alarm unit 14 is activated to remind the staff to perform maintenance. When it is found that a passenger is close to the rope 2, in addition to sending a signal to the alarm unit 14 to remind the passenger to stay away, a signal is also sent to the control unit to control the lifting and lowering speed of the rope 2. For example, after the train enters the station, when it is detected that the passenger is close to the rope 2, the control unit controls the rope 2 to rise slowly, giving the passenger time to react away from the rope 2, so as to avoid the rope 2 rising too fast and the passenger not reacting quickly and being accidentally injured. When the passenger is far away from the rope 2, the control unit controls the rope 2 to rise quickly, so that the passenger can get on and off the train faster.

[0045] In addition, the video monitoring unit 13 can also be connected to the central control platform by telecommunications to transmit the monitoring images to the central control platform in real time, so that the staff in the station can remotely view the platform conditions and remotely control the barrier mechanism.

[0046] The tension sensor 11 is used to monitor the tension and integrity of the rope 2 in real time. When it is detected that the tension of the rope 2 is too large, for example, a passenger pulls or presses on the rope 2, or when it is detected that the rope 2 is broken, a signal is sent to the alarm unit 14 and the control unit at the same time. The alarm unit 14 reminds the passenger or station staff, and the control unit controls the rope 2 to stop moving.

[0047] In this embodiment, the lifting columns 1 at both ends of the platform are also provided with end protection units for warning non-staff to leave. The end protection unit preferably includes an image recognition sensor and a voice announcer. When the approaching person is identified as a staff member, the end protection unit does not issue a warning. Specific identification can be through face, clothing, or work badge information. The end protection unit can be connected to the central control platform by telecommunications, obtain the staff information entered by the central control platform and compare it with the currently identified personnel information to determine whether it is a staff member, and the central control platform issues a voice warning.

[0048] Furthermore, the lifting columns 1 at both ends of the platform are provided with a vehicle entry detection sensor and a vehicle exit detection sensor, both of which are electronically connected to the control unit for detecting the entry and exit of the train, and then controlling the lifting and lowering of the rope 2 according to the detected signal.

[0049] In addition, a gravity lifting structure is also provided in the lifting column 1, including a pulley located at the upper part of the lifting column 1 and a pull rope sliding on the pulley, one end of the pull rope is connected to the movable part, and the other end is connected to the gravity block. When a power outage occurs, the driving device loses its braking effect, and the movable part moves upward under the action of the gravity part, driving the rope 2 to rise, releasing the blocking state, and ensuring that passengers can get on and off the platform normally when the power is off. A pull rope encoder 15 is provided on one side of the pulley, which is used to obtain the lifting height of the rope 2 in real time, so as to accurately control the lifting and lowering of the rope 2, and it is electrically connected to the control unit.

[0050] Since the rope 2 is usually relatively thin and difficult to be found, in order to prevent passengers from accidentally bumping into the rope 2, a warning tape 3 is provided on the rope 2. The warning tape 3 is preferably yellow and preferably extends vertically to connect multiple ropes 2.

[0051] Usually, the purpose of passengers approaching the edge of the platform is to check the corresponding position of the carriage and the arrival of the train. In this application, a display unit 4 is provided on the front side of the lifting column 1 and is connected to the central control platform by telecommunication. The display unit 4 includes a digital display and a display screen distributed up and down. The digital display displays the carriage number of the carriage corresponding to the lifting column 1, and the display screen displays the train arrival and departure information, thereby fundamentally reducing the need for passengers to approach the edge of the platform.

[0052] In addition, a projection unit 16 is provided on the top of the lifting column 1, which is telecommunication-connected to the central control platform and is used to project the car number in front of the car door, so that passengers can quickly know the location of the car corresponding to their tickets, avoiding the need for passengers to search for the corresponding car along the edge of the platform, and further reducing the need for passengers to get close to the edge of the platform.

[0053] In the present application, the safety monitoring system also includes a remote control unit, which is electrically connected to the control unit. Through the remote control unit, the barrier mechanism is remotely controlled to perform actions such as full opening, half opening, and reconnection switching, making it convenient for station staff to operate.

[0054] The utility model provides a platform safety monitoring system, which provides a blocking mechanism to physically block passengers and prevent them from approaching the edge of the platform. It is also equipped with a tension sensor 11, a sensing unit 12, a video monitoring unit 13, an alarm unit 14 and a control unit to promptly detect and stop unsafe behaviors of passengers. In addition, it can flexibly control the operation and stop of the blocking mechanism according to the detection information, thereby improving the safety of the use of the blocking mechanism and performing effective safety monitoring and protection for platform passengers.

[0055] In addition, by using the display unit 4 and the projection unit 16, the need for passengers to get close to the edge of the platform is reduced from the source, thereby improving the safety protection effect.
