Description

Technical Field

[0001] This utility model relates to the field of rail transit training, and in particular to a local control panel for a training platform screen door. Background Technology

[0002] In urban rail transit systems, the platform screen door local control panel (PSL) is a critical piece of equipment for ensuring platform safety, its importance lying in its dual functions of emergency operation and safety monitoring. The PSL is typically located at the front of the train on each platform—the core area where the driver disembarks at each station to monitor passenger boarding and alighting. It primarily handles emergency operations such as manually controlling the opening, closing, and interlocking of the platform screen doors, acting as a "safety valve" for train drivers and station staff in the event of a sudden platform screen door malfunction. The station's automatic platform door control system, operating in conjunction with PSL, integrates vehicle operation signals to automatically open and close the platform screen doors, ensuring seamless passenger boarding and alighting with train operation. However, a failure in this sophisticated system can have a cascading impact on the entire line's train operations: at best, it can lead to downgraded train operation; at worst, it can cause trains to stop and become immobile, directly causing a decline in operational efficiency or even widespread delays, posing a serious challenge to the reliability of the urban transportation network.

[0003] Currently, there are significant pain points in the operation training for platform screen door (PSL) systems, urgently requiring technological innovation. Due to the special nature of PSL equipment, the long-standing reliance on "oral instruction" instead of hands-on practice has exposed a deep-seated problem of the disconnect between theory and practice. Drivers and train operators lack exposure to the actual PSL operating interface, and their judgment and handling of platform screen door malfunctions remain at the conceptual level. This leads to errors and omissions in actual emergency operations, becoming potential risk points for operational delays. For example, when encountering platform screen door interlock failure, undervoltage faults, or abnormal door locking, personnel without practical training may delay fault handling due to unfamiliarity with operating procedures or the control panel interface, further amplifying the impact of the incident.

[0004] Against this backdrop, the development of practical training devices for operating platform screen doors has become an essential need for the industry. Utility Model Content

[0005] To address the lack of training devices for operating platform screen doors in the existing technology, this utility model provides a local control panel for training platform screen doors.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] Please see Figures 1 to 3 The first embodiment of this utility model provides a local control panel for a training shielded door, comprising:

[0046] The enclosure 10 can be made of metal or non-metal. Metal materials include cold-rolled steel, stainless steel, and aluminum alloy, while non-metal materials include engineering plastics and fiberglass. In this embodiment, the enclosure 10 is made of SUS304L stainless steel, which has high mechanical strength and excellent corrosion resistance. The enclosure 10 can have various shapes, such as cuboids, cylinders, or other polygonal shapes. Cuboids are the most common shape, with a simple and regular structure and six right angles, facilitating standardized production, design, and manufacturing. Cylindrical enclosures, due to their lack of sharp edges, can reduce the risk of collision injuries in areas with high personnel activity. Furthermore, the circular structure distributes external pressure more evenly, making it more resistant to impacts. In this embodiment, since this invention provides a training shielded door local control panel, the enclosure 10 is designed as a cuboid for easy placement, illustrative explanation, and operation during training.

[0047] Please see Figure 1 and Figure 2 The housing 10 has a top surface 10e and a bottom surface 10f opposite each other along the direction of gravity, a front surface and a rear surface opposite each other along the line of sight when the operator looks directly at the housing 10, and a left side surface and a right side surface perpendicular to the line of sight and located on both sides respectively; in this embodiment, the front surface is the first surface 10a, the right side surface is the second surface 10b, and the left side surface is the third surface 10c. Figure 1 (not shown in the image), and the following is the fourth surface 10d ( Figure 1 (Not shown in the image). The interior of the box body 10 is provided with a receiving cavity, and the first surface 10a of the box body 10 has an opening. The first surface 10a of the box body 10 is provided with a box door 20. The material of the box door 20 can be the same as that of the box body 10 to facilitate synchronous production and manufacturing. The box door 20 is rotatably connected to the box body 10, specifically it can be a hinged connection, a pivot connection, such as a hinge connection, a pin connection, etc.

[0048] Please also refer to Figures 3 to 5 The enclosure door 20 is provided with a first operation panel 30, which includes a shielding door closed and locked indicator light 31, a PSL operation area 32, and an IBP operation status indicator light 33. The second side 10b of the enclosure body 10 is provided with a second operation panel 40. The second operation panel 40 is provided with a shielding door closed and locked indicator light fault switch 41 and an IBP operation status indicator light fault switch 42. The shielding door closed and locked indicator light fault switch 41 is used to control the opening and closing of the shielding door closed and locked indicator light 31. The IBP operation status indicator light fault switch 42 is used to control the opening and closing of the IBP operation status indicator light 33.

[0049] The specific usage method of the training screen door local control panel in this embodiment is as follows:

[0050] Observe the first operation panel 30: Trainees should check the shielding door closed and locked indicator 31, PSL operation area 32, and IBP operation status indicator on the first operation panel 30 on the door 20 to understand their normal status display. For example, under normal circumstances, the shielding door closed and locked indicator 31 will light up when the shielding door is closed and locked.

[0051] PSL Operation Area 32 Operation: In PSL Operation Area 32, following the standard operating procedures, train operators to perform operations such as closing and disengaging the platform screen doors by inserting a dedicated key. For example, when opening / closing the doors, the operator inserts the operation permission key, turns it clockwise to the "PSL Permit" position, and presses the "Open Door" button; the entire sliding door on one side will open. Pressing the "Close Door" button will close the entire sliding door on one side, simulating the opening / closing process of the entire platform screen door. When disengaging the interlock, insert the "Interlock Disengage" key into the corresponding switch on the PSL, turn it to the interlock disengage position and hold it, simulating the process of sending a command to the signaling system to allow the train to leave the platform.

[0052] Simulation of the malfunction of the shielding door closing and locking indicator light: The instructor operates the shielding door closing and locking indicator light malfunction switch 41 on the second operation panel 40 on the second side 10b of the enclosure 10, pressing it to switch the shielding door closing and locking indicator light 31 to the off state, simulating a malfunction of the shielding door closing and locking indicator light 31. At this time, the trainees observe that the indicator light is off on the first operation panel 30. Then, according to the fault handling procedure, they conduct troubleshooting and operation training in the PSL operation area 32, such as checking relevant circuit connections and judging the cause of the fault. The operation training is as described above and will not be elaborated further here.

[0053] IBP Operation Status Indicator Fault Simulation: Similarly, the instructor operates the IBP operation status indicator fault switch 42 on the second operation panel 40, pressing it to switch the IBP operation status indicator 33 to the off state, simulating a fault in the IBP operation status indicator 33. Trainees observe the indicator light going out on the first operation panel 30, and then follow the established fault handling procedures to conduct corresponding troubleshooting and troubleshooting training, such as confirming the operation permission relationship between the IBP disk and the PSL disk, and troubleshooting circuit problems.

[0054] In the first embodiment of this utility model, the circuit can be configured in various ways to achieve the above-mentioned functions. On one hand, conventional circuit configurations can be used. These conventional circuit configurations refer to circuit combinations known in the art that can achieve similar functions. These conventional circuits are typically composed of common electronic components, such as indicator lights, switches, and power supplies, connected and configured according to established circuit principles and design specifications. For example, in a test lamp circuit, a common series circuit can be used. This circuit connects the test lamp switch, power supply, off and locked indicator light, PSL operation status indicator light, interlock contact indicator light, and IBP operation status indicator light in series to detect whether the indicator light functions correctly. Those skilled in the art can select appropriate conventional circuit configurations based on different application scenarios and performance requirements, and adjust and optimize their parameters accordingly to meet the circuit functional requirements of this utility model.

[0055] On the other hand, one embodiment of this utility model also provides a circuit scheme formed by the circuit diagram shown in FIG6. This circuit diagram illustrates in detail the connection relationships and layout of each electronic component, which will not be described in detail here. However, it should be noted that this utility model is not limited to this specific circuit diagram design. Those skilled in the art can make adaptive adjustments and modifications to the circuit diagram according to actual conditions. For example, a power supply and a switch can be added to control the air supply component, etc., as long as these additions and / or replacements do not cause the circuit to fail to achieve the functional operation required by this application, they should all fall within the protection scope of this utility model.

[0056] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 4The shielding door closed and locked indicator light 31 is located above the PSL operation area 32 on the first operation panel 30. Positioning this indicator light above the PSL operation area 32 serves several purposes. First, it aligns with the human eye's tendency to prioritize observing the top of the operation panel, allowing for quicker confirmation of the shielding door's closed and locked state and determining safe driving conditions, avoiding misjudgments or omissions due to the indicator light's inconspicuous location. Second, the indicator light 31 reflects the shielding door's status, and the PSL operation area 32 is used to control the shielding door; the two are functionally closely related. Placing the indicator light above the operation area follows the logical sequence of "understanding the status - performing the operation," allowing operators to naturally obtain the shielding door's status information first and then perform corresponding operations, resulting in a smoother and more logical operation process. Furthermore, placing the indicator light above the operation area provides some spatial isolation from switches, buttons, and other controls within the operation area. When operators insert keys or press buttons in the PSL operation area 32, the number of indicator lights obstructed by hand movements can be reduced, ensuring that the indicator light status can be continuously observed during operation. This avoids missing changes in indicator light status due to obstructed vision, which could affect the judgment of the operation of the platform screen door.

[0057] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 4 The PSL operation area 32 is located above the IBP operation status indicator 33 on the first operation panel 30. By placing the PSL operation area 32 above the IBP operation status indicator, the continuity of the operation process is further optimized. After completing the PSL operation, the operator can naturally look down to check the IBP operation status without frequently adjusting their line of sight, thus improving operational efficiency.

[0058] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 4The PSL operation area 32 is equipped with a PSL operation status indicator light 321, an interlock release indicator light 322, a PSL operation control switch 323, and an interlock release switch 324. The PSL operation control switch 323 controls the opening and closing of the PSL operation status indicator light 321; the interlock release switch 324 controls the opening and closing of the interlock release indicator light 322. The PSL operation status indicator light, controlled by the PSL operation control switch, displays the current operating status of the PSL operation area 32, such as whether it is in a normal operable state or whether a malfunction is affecting operation, allowing operators to understand the operating status of the PSL operation area 32 and determine whether appropriate operations can be performed. The interlock release indicator light 322, controlled by the interlock release switch 324, indicates whether the interlock status of the platform screen door has been released. When the interlock release indicator light 322 is lit, it indicates that the interlock has been released, allowing operations that are restricted under normal interlock conditions. However, it also reminds operators that the platform screen door is in a special state and requires careful operation to ensure safety.

[0059] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 4 The PSL operation status indicator 321 and the PSL operation control switch 323 are arranged sequentially along the direction of gravity; and / or the interlock release indicator 322 and the interlock release switch 324 are arranged sequentially along the direction of gravity. This design conforms to ergonomics and operating habits, allowing operators to naturally observe the indicator status from top to bottom before performing the switch operation, resulting in a smooth process. At the same time, this layout makes each group of indicator lights and switches a self-contained unit, easy to identify and distinguish, reducing the probability of misoperation and improving operational accuracy and efficiency. In addition, the layout in the same vertical area ensures that the indicator lights and switches have good visibility and operability at different angles and positions, which helps operators respond quickly in emergency situations.

[0060] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 5 The shielding door closed and locked indicator light fault switch 41 is located above the IBP operation status indicator light fault switch 42 to match the positional relationship between the shielding door closed and locked indicator light 31 and the IBP operation status indicator light 33 on the first operation panel 30, so as to avoid misoperation and facilitate the smooth progress of teaching.

[0061] In a preferred embodiment of this utility model, please also refer to Figure 1 and Figure 3The PSL operation control switch and / or the interlock release switch 324 are key switches. Designing the PSL control switch and interlock release switch 324 as key switches effectively manages operation permissions; only authorized personnel with specific keys can operate the system, ensuring safe and standardized operation. The complex operation process prevents accidental touches and ensures the stability of the platform screen door system. The key insertion and removal status is clearly displayed, facilitating quick assessment by staff. Furthermore, key usage can be linked to operator and time information, facilitating operation recording and traceability. In case of problems, responsibility can be clearly identified, causes analyzed, and a basis for future improvements provided.

[0062] In a preferred embodiment of this utility model, please refer to Figure 7 The shielding door closed and locked indicator light 31, the IBP operation status indicator light 33, the PSL operation status indicator light 321, and the interlock release indicator light 322 are all equipped with indicator light labels 35. By setting indicator light labels 35, the meaning of each indicator light can be clearly indicated, which can help operators quickly and accurately identify the status represented by different indicator lights, avoid confusion, and improve the accuracy and efficiency of operation.

[0063] In a preferred embodiment of this utility model, please also refer to Figure 3 and Figure 4 The first operation panel 30 is equipped with a test light button 34, which is used to check whether the indicator light is working properly. By setting the test light button 34, staff can quickly check whether the indicator light is working properly, promptly detect and eliminate indicator light faults, and ensure that it can accurately indicate the relevant status.

[0064] It should be noted that this utility model provides a training shielded door local control panel, which needs to restore the real fault environment for trainees and facilitate trainees to quickly identify the functions and roles of each indicator light and switch. Therefore, for trainees who are new to or have little experience, it is necessary to have a more intuitive understanding of the fault situation and how to quickly get started with practical operation in the face of the fault, and complete the training through continuous successful practical operation.

[0065] Therefore, the training platform screen door local control panel provided by this utility model is not a complete replica of the platform screen door local control panel actually used on the market. Instead, it sets up switches for controlling the opening and closing of the platform screen door closing and locking indicator light and switches for controlling the opening and closing of the IBP operation status indicator light, thereby realizing the scenario of malfunction of the platform screen door closing and locking indicator light and the IBP operation status indicator light, so as to provide trainees with a realistic fault environment. At the same time, in the preferred embodiment, its operation panel has been further arranged in a more reasonable manner, thereby helping trainees to efficiently master the key points of operation, enhance their confidence in practical operation, reduce the error rate, and more easily cope with the various local control panel operation scenarios in rail transit.

[0066] Please see Figures 8 to 11 The second embodiment of this utility model provides a local control panel for a training shielded door. The difference between this embodiment and the first embodiment is that: the housing 10 is provided with a first ventilation port 11 and a second ventilation port 12; the housing 10 is provided with an air supply assembly 14 for supplying fresh air from outside the housing 10 through the first ventilation port 11 and exhausting it to the outside of the housing 10 through the second ventilation port 12; the housing 10 is provided with a drying and dustproof assembly 13 for drying and removing dust from the gas entering through the first ventilation port 11.

[0067] Training devices are typically used frequently and are not located in the relatively independent and stable space of a subway station driver's platform screen door control panel. The environment is characterized by controllable temperature and humidity and low dust levels. Furthermore, the indicator lights in training devices are usually battery-powered, primarily because their usage scenarios are flexible and varied. They may be used in locations without fixed power outlets, and battery power provides independent and convenient power support, ensuring the training device can be used at any time without being restricted by power wiring. Battery power also enhances the portability of the training device, facilitating training in different locations. However, prolonged training can easily lead to heat generation inside the housing 10. An internal ventilation system consisting of the first vent 11, the second vent 12, and the air supply assembly can quickly and effectively dissipate heat from the device, ensuring stable temperature operation and guaranteeing the continuity of the training process and the reliability of the equipment. At the same time, since training devices are specialized teaching aids, they are not mass-produced like conventional equipment, requiring a balance between cost and durability. Because it is frequently used for practical training, the internal electronic components are easily damaged by environmental factors. Therefore, installing a drying and dustproof component 13 at the first air inlet 11 can prevent dust and moisture from entering the housing 10, avoiding the impact of dust accumulation on equipment performance or moisture causing circuit failures, thereby extending the service life of the training device, reducing maintenance costs, and providing stable hardware support for training work. Preferably, to improve versatility and reduce costs, the air supply component can be a fan, which is installed on the inner wall of the housing 10 at the second air inlet 12.

[0068] The structural design of setting the drying and dustproof component 13 at the first vent 11 (air inlet) and the air supply component at the second vent 12 (air outlet) can dry and remove dust from the gas when fresh air enters. Since the fan sends the gas out, it can prevent external gas from entering through the second vent 12, thus eliminating the need to add the drying and dustproof component 13 to the second vent 12 and reducing costs.

[0069] In a more preferred embodiment of this utility model, please refer to Figure 7The drying and dustproof assembly 13 includes a support bracket 131 disposed on the outer wall of the housing 10 at the first vent 11, and a drying unit 132 and a dustproof unit 133 inserted within the support bracket 131, facilitating periodic replacement of the drying unit 132 and / or the dustproof unit 133. The drying unit 132 may be a silica gel drying sheet or a calcium chloride drying sheet, while the dustproof unit 133 may be non-woven fabric, activated carbon fiber, etc. In this embodiment, the drying unit 132 is a calcium chloride drying sheet, and the dustproof unit 133 is a non-woven fabric. Preferably, the dustproof unit 133 is located on the side of the support bracket 131 away from the first vent 11, while the drying unit 132 is located on the side of the support bracket 131 closer to the first vent 11, thereby achieving dustproofing before drying and extending the service life of the drying unit 132.

[0070] In a preferred embodiment of this utility model, please refer to Figure 11 The first vent 11 and the second vent 12 are arranged opposite to each other, which facilitates the formation of an air convection channel, allowing external cold air to enter quickly, displace the hot air inside the box, and be discharged, effectively removing the heat generated by the operation of the device, enhancing the heat dissipation effect, and ensuring that the internal equipment of the training device operates stably at a suitable temperature. In this embodiment, the first vent 11 is located on the third surface 10c, and the second vent 12 is located on the second surface 10b.

[0071] In a preferred embodiment of this utility model, please refer to Figure 11 The first vent 11 and the second vent 12 are staggered vertically, which extends the airflow path within the housing 10, allowing the air to fully contact the internal equipment for heat dissipation. Simultaneously, in conjunction with the drying and dustproof component 13, it reduces the direct entry of dust and other impurities into the housing 10, better protecting the equipment and lowering the risk of malfunctions caused by dust accumulation. In this embodiment, the first vent 11 is located on the upper part of the third surface 10c, and the second vent 12 is located on the lower part of the second surface 10b.

[0072] In a preferred embodiment of this utility model, please refer to Figure 7 The first side 10a of the box 10 is provided with a box identification mark 36, which can easily identify the training device, facilitate management and operation, and help to quickly locate and distinguish devices with different functions.

[0073] In a preferred embodiment of this utility model, please refer to Figure 3 The bottom surface 10f of the box 10 is provided with a negative pressure support 50. The negative pressure support 50 can be a silicone suction cup. By providing the negative pressure support 50 on the bottom surface 10f of the box 10, the adsorption force between the box 10 and the placement surface can be enhanced, preventing the box 10 from accidentally sliding or tipping over, and ensuring that the training device remains stable during use.

[0074] In a preferred embodiment of this utility model, please refer to Figure 3 A lock cylinder 21 is installed on the door 20, and a handle 22 is locked onto the lock cylinder 21. A keyhole is provided on the handle 22.
