TECHNICAL FIELD

[0001] The present application relates to rail transit signal systems, in particular to a roller shutter platform door and a control method, device and medium thereof. BACKGROUND

[0002] The existing rail transit platform door has three forms of lifting type, folding type and horizontal moving type, each having advantages and disadvantages.

[0003] The folding type and lifting type platform door are used for high-speed rail platforms, which are arranged about 1.2 meters away from the edge of the platform, which increases the width of the platform and increases the construction cost. At the same time, due to the limitations of safety and door body mechanical design, it cannot be used for subway platforms, especially the limited installation space of underground platform height and width.

[0004] The horizontal moving type platform door mainly has the problems of large door body quality, complex structure, high material cost and difficult construction. At the same time, it has poor compatibility for mixed running of various trains. Although some horizontal moving type platform doors increase the width of the sliding door body, the compatibility is not completely solved due to the limitation of the distance between two doors.

[0005] After searching, Chinese patent publication No. CN111762204A discloses a lifting and folding type platform protection device suitable for various vehicle types, specifically discloses a lifting and folding platform door, a stand column and an end door. A plurality of lifting and folding platform doors and stand columns are alternately arranged along the longitudinal direction of the track to form a longitudinal platform door, and the two ends of the longitudinal platform door are provided with transverse end doors. The width of each lifting and folding platform door is equal, and the sum of the widths of all lifting and folding platform doors accounts for more than 80% of the total length of the longitudinal platform door. The lifting and folding platform door includes a plurality of shielding folding pieces which are hingedly connected in sequence, and the two ends of the shielding folding piece are slidably arranged on the stand columns on both sides. The existing patent realizes the shielding function of the platform door by folding and unfolding the lifting and folding platform door instead of the fixed door and the sliding door of the traditional platform door. However, the existing patent is only suitable for high-speed rail platforms and is arranged far away from the edge of the platform, which also increases the width of the platform and increases the construction cost.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] Example 1 like Figure 1 As shown, this invention discloses a roller shutter platform door. This roller shutter platform door realizes the functions of platform isolation, shielding, and passenger passage. Compared with existing lifting, folding, and sliding technologies, this invention adopts a roller shutter structure, which has the characteristics of simple mechanical structure, small installation space, convenient construction and debugging, and high reliability and safety. It reduces the amount of installation and debugging work, shortens the installation and debugging cycle, improves the efficiency of fault diagnosis, and reduces the impact of component failures on operation. It is applicable to urban rail, suburban rail, high-speed rail elevated platforms, and underground platforms.

[0025] The roller shutter platform door includes a roller shutter door 1, a guide device 2, a transmission device 3, a drive device 4, an electronic control unit 5, and a mechanical foreign object detection device 10. The electronic control unit 5 receives external system commands and controls the driving device 4 to rotate, the driving device 4 controls the transmission device 3 to rotate in the expected direction, and the transmission device 3 controls the roller shutter movable door 1 to move in the expected direction; the guide device 2 is connected to the roller shutter movable door 1 and is used for moving the roller shutter movable door 1 along a fixed track; and the mechanical foreign matter detection device 10 is installed at the bottom of the roller shutter movable door 1 and is used for detecting foreign matters during the movement of the roller shutter movable door 1.

[0026] As a preferred embodiment, the roller shutter platform door is arranged along the platform edge array, instead of the fixed door, emergency door and sliding door of the conventional platform door, and can be applied to high-speed rail platforms and subway platforms.

[0027] As a preferred embodiment, as shown in Figure 3 The roller shutter movable door 1 adopts a rigid hinge type roller shutter structure capable of bearing the tunnel wind pressure and the body leaning pressure, includes rigid curtain pieces and hinge modules, and the hinge modules are installed at the connection positions of adjacent rigid curtain pieces, that is, the rigid hinge type roller shutter structure of the application. Instead of using a continuous flexible curtain piece, the rigid hinge type roller shutter structure is composed of a series of rigid curtain pieces connected by high-performance hinges. In this way, the rigid hinge type roller shutter structure can be bent and wound as a whole and can be absolutely rigid when unfolded. The rigid curtain piece can be made of high-strength aluminum alloy, is extruded into a shape, has a reinforcing rib inside, and can provide extremely high bending and torsional stiffness. The high-performance hinge is located at the connection position of adjacent curtain pieces, is made of a metal hinge (such as zinc alloy or stainless steel) formed by precise casting or stamping, and is composed of a hinge shaft, a bearing (usually nylon or copper sleeve) and a connecting arm. This is the key to achieving the combination of rigidity and flexibility, allowing the curtain piece to rotate around the winding shaft when winding (flexible), but effectively transmitting the load when the curtain piece is unfolded into a plane, locking multiple curtain pieces into a rigid whole plane.

[0028] Therefore, compared with the ordinary flexible roller shutter, the rigid hinge type roller shutter structure of the application has the following advantages: 1) High structural strength and strong wind pressure resistance. After the rigid hinge type roller shutter structure of the application is unfolded, the hinges lock the curtain pieces into a whole plane, which is similar to a movable metal wall. The rigidity of the curtain pieces is also high, so that the tunnel wind pressure and the body leaning pressure can be effectively borne. 2) Good flatness. After the rigid hinge type roller shutter structure of the application is unfolded, the whole curtain surface is absolutely flat and has no wave-shaped deformation.

[0029] Therefore, the rigid hinge type roller shutter structure of claim 1 of the application solves the contradiction between rigidity and windability through the precise mechanical hinge module, so that it surpasses the conventional flexible roller shutter in almost all performance dimensions.

[0030] As a preferred embodiment, as shown in Figure 2As shown, the guide device 2 adopts an H-shaped profile that can withstand tunnel wind pressure and human body leaning pressure. The H-shaped profile is installed on both sides of the roller shutter door 1, and its guide groove is adapted to the roller shutter door 1. The cross-sectional shape of the H-shaped profile is similar to "I" or "H". This design gives it extremely high bending strength and compressive strength in both horizontal and vertical directions.

[0031] As a preferred embodiment, the transmission device 3 uses a driven wheel matched with the drive device 4 and is redundantly configured. Two sets of drive devices 4 and transmission devices 3 are configured accordingly, with a redundant design. One set of drive devices 4 includes a gear-type brushless DC motor and planetary gears connected to each other, and the planetary gears are connected to the driven wheel for transmission.

[0032] The invention features a redundant drive device design, which avoids the impact of a single drive failure on door opening and closing, resulting in higher availability.

[0033] As a preferred implementation, the electronic control unit 5 is equipped with an external communication interface, a communication bus, and a hard-wired interface for receiving control commands from the signal system, vehicle system, or other equipment, thereby enabling precise matching with the train doors and avoiding the large-length openings of lift-type or lateral-type doors.

[0034] As a preferred embodiment, the roller shutter platform door also includes an equipment box 6 for installing the transmission device 3, the drive device 4, and the electronic control unit 5.

[0035] This invention, by providing an equipment box for installing the transmission device, drive device, and electronic control unit, avoids these electronic and transmission mechanisms from being corroded by external rainwater, thus greatly improving the service life of the equipment.

[0036] Example 2 like Figure 4 As shown, a control method for the roller shutter platform door includes the following steps: Step S1: The electronic control unit 5 obtains door opening and closing control commands from the signal system, door system, or other control devices through the interface; In step S2, after receiving the door opening command, the electronic control unit 5 activates the safety operation control drive device 4 to rotate. In step S3, the driving device 4 drives the transmission device 3 to rotate in the forward direction, and the transmission device 3 drives the roller shutter door 1 to move upward in the guide device 2, thereby realizing the opening operation of the roller shutter door 1. Step S4: After receiving the door closing command, the electronic control unit 5 controls the safety operation to rotate the drive device 4 in the opposite direction. In step S5, the driving device 4 drives the transmission device 3 to rotate in the opposite direction, and the transmission device 3 drives the roller shutter door 1 to move downward in the guide device 2, thereby realizing the closing operation of the door.

[0037] Step S6: During the closing operation, when the mechanical foreign object detection device 10 detects a foreign object, the detection signal is transmitted to the drive device 4 through mechanical force. After the electronic control unit 5 collects the force signal, it controls the drive device 4 to rotate in the opposite direction to open the roller shutter door 1. Step S7: During the door opening and closing operation, if the electronic control unit 5 detects a fault in the drive device 4, it drives another drive device 4 to run; if other faults are detected, it stops the drive device 4 from rotating.

[0038] This invention can precisely match train doors, avoiding the large opening lengths of lifting or sliding doors, and preventing people or objects from being trapped in the gap between the platform door and the train door, thus improving safety.
