Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, and in particular to a device for detecting the opening and closing status of monorail train doors and platform doors. Background Technology

[0002] A monorail is a special type of railway train that typically runs on a single track. It is mainly divided into two types: suspended and straddle-type. It is primarily used as a medium-capacity rail transit mode in densely populated urban areas, such as between the city center and satellite cities, between urban areas and major transportation hubs like airports, and between the city center and large suburban residential areas.

[0003] To prevent passengers from falling onto the train tracks while waiting, operators have installed platform screen doors at each station, using a linkage system between the train doors and platform screen doors. This ensures the safety of every passenger and significantly improves the waiting environment. However, in actual operation, drivers frequently forget to open the doors and platform screen doors. This not only causes train delays and reduces operational efficiency but also poses a serious threat to passenger safety. Current equipment and systems cannot comprehensively, reliably, and in real-time monitor the status of the doors and platform screen doors, and therefore cannot effectively prevent or solve the problem of drivers forgetting to open them. Therefore, we propose a monorail train door and platform screen door opening / closing status detection device. Utility Model Content

[0020] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, 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 used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0023] Please see Figure 1 This utility model provides a technical solution: a device for detecting the opening and closing status of monorail train doors and platform doors, including a sensor module, a control module, an alert module and a data storage module.

[0024] The sensor module includes door sensors and platform door sensors. The door sensors are installed on each door of each train car. Optional sensor types include magnetic sensors, photoelectric sensors, or mechanical switches. For example, photoelectric sensors are chosen because they offer fast response, high accuracy, and strong anti-interference capabilities. The photoelectric door sensors are securely installed on the inside of the door frame, ensuring their detection direction is precisely aligned with the door's movement trajectory, thus accurately detecting whether the door is open or closed. During installation, the selected photoelectric door sensors are firmly fixed to the inside of the door frame using screws or special clamps according to design requirements. It is crucial to ensure that the sensor's detection direction is precisely aligned with the door's movement path, guaranteeing that the sensor can stably and accurately detect changes in door position throughout the entire opening and closing process. The platform door sensors are installed at each platform door, using the same type of sensor as the door sensors, such as photoelectric sensors. The platform door sensors are installed on the side of the platform door frame closest to the track. This position effectively detects the platform door's status while minimizing interference from external factors, ensuring accurate detection results. During installation, the platform screen door sensor is installed on the side of the platform screen door frame closest to the track. The appropriate installation method is selected based on the specific structural characteristics of the platform screen door. For example, adhesive or embedded methods can be used to install the sensor, ensuring that the sensor can effectively detect the status of the platform screen door while avoiding interference from passenger boarding / alighting and other external factors.

[0025] Control Module: A microcontroller or PLC is selected as the control core. The main function of this control module is to receive signals from the door sensors and platform door sensors, perform logical analysis and judgment on these signals, control the working state of the alert module, and establish a communication connection with the train control system to achieve information interaction and collaborative work. In practical applications, the control module can be installed in the train's electrical control cabinet, which provides a relatively stable environment, effectively preventing dust, water, and shock, and facilitating wiring connections to sensors, alert modules, and communication with the train control system. It also allows for centralized maintenance and repair by technicians. From the perspective of minimizing transmission loss by being close to the signal source, it can be installed near the convergence area of ​​the door and platform door sensor wiring, shortening the signal transmission distance and enhancing system response speed and stability. If a microcontroller is selected as the control module, program code is written using a corresponding programming language based on the pre-designed control logic. After the code is written, it is burned into the microcontroller, and the microcontroller's input / output ports are configured appropriately, connecting to the output signal ports of the door sensor and platform door sensor, as well as the control signal input port of the alert module. If a PLC is used as the control module, the program is written in the PLC programming software using ladder diagrams or other suitable programming languages, according to the control requirements. After the program is written, the PLC's input / output modules are correctly configured to ensure accurate connection between them and the sensors and alert module, and to establish a stable and reliable communication connection with the train control system. The above techniques can be implemented by those skilled in the art through simple programming; therefore, their specific structure and working principle will not be elaborated upon in this paper.

[0026] Alert Module: When the control module detects that a train door or platform door is not open, the alert module activates. The alert module can use a buzzer, LED light, or voice prompt device to promptly remind the driver by issuing audible and visual alarm signals.

[0027] Data storage module: The data storage module is responsible for recording data related to events where train doors and platform doors are not opened. Storage methods include SD card storage, EEPROM storage, or wireless transmission to external storage devices, ensuring secure data storage and traceability.

[0028] Connect buzzers, LED lights, or voice prompt devices to the corresponding control ports of the alert module and perform comprehensive debugging. By simulating a situation where the train door or platform door is not open, verify that the alert module can correctly and accurately emit audible and visual alarm signals when receiving the alert signal from the control module. Initialize the SD card or EEPROM to ensure that the data storage module can correctly and stably record data on train door and platform door closure events. If a wireless transmission method is used, the parameters of the wireless communication module need to be carefully configured to ensure that the data can be transmitted securely and efficiently to the designated storage device or server.

[0029] It should be noted that this utility model is a device for detecting the opening and closing status of monorail train doors and platform screen doors. When the train arrives at the station and comes to a complete stop, the control module immediately starts the detection program for the status of all doors and corresponding platform screen doors. If all doors and platform screen doors are found to be open normally after detection, the system will automatically enter standby mode, waiting for the next train arrival detection. Once a door or platform screen door is detected to be closed, the control module will quickly activate the reminder module, which will then issue an audible and visual alarm signal to inform the driver that the door is not open. After receiving the reminder signal, the driver can manually open the closed door or platform screen door in a timely manner. During the opening and closing of the doors and platform screen doors, the control module always maintains linkage with the train control system to ensure that the two act synchronously, ensuring the smooth and safe boarding and alighting of passengers. At the same time, the system's data storage module will record relevant data on the events of doors and platform screen doors not opening, such as the time and specific location of the event, for subsequent analysis and improvement of the operation. Compared with existing monorail train door and platform door opening and closing status detection devices, this utility model is designed to monitor the status of doors and platform doors in real time, automatically remind the driver, realize linkage control and record event data, effectively improve the safety and efficiency of train operation and reduce operating costs.
