[0002] Both my country's EMU train platforms and ordinary train platforms are constructed in an open style. There are no safety shielding doors on the platforms, and order is maintained by individual managers. There are safety white lines, which can hardly meet the development needs of existing high-speed railways.

[0003] The anti-pinch structure of station shield doors usually lacks remote monitoring and operation functions. Staff need to inspect and operate the equipment on site, which not only increases maintenance costs, but also limits the timely response to equipment status. Traditional systems use simple switches or sensor feedback, but have limited capabilities in data processing and conversion. When running for a long time, especially under high load or harsh environmental conditions, traditional systems will face problems of heat accumulation and overheating of components.

The staff sends the platform screen door opening and closing signal to the two-way transmitter installed inside the shell through the PC mobile terminal. After the RS485 receiving unit contained in the two-way transmitter receives the control signal, the frequency keying receiving unit receives the heat collection keying data issued by the PC mobile terminal accordingly. The data transmission unit transmits the keying data to the data sending unit in a limited time according to the time-limited output of the time-limited relay unit, and then the data sending unit sends it to the HART processor, which converts the data. With the data transmission of the data sending unit, the status receiving unit receives the operating data of the microcontroller accordingly, and sends it to the positioning status identification unit through the data transmission unit. After the positioning status identification unit realizes the operating status of the microcontroller, it is sent to the PC mobile terminal through the RS485 sending unit for feedback display. After the data receiving unit receives the keying data sent by the data sending unit, the frequency keying reading unit reads it accordingly, and converts it through the keying character conversion unit. The element converts the data into character data that can be used by the microcontroller. After the time-limited memory unit stores the instruction characters for a limited time, the character import unit imports them into the microcontroller. The microcontroller directly starts the laser sensor to monitor the opening and closing of the shielding door. When the components inside the shell are running, the heat exchange and dissipation component is enabled.

The U-shaped delivery pipe 1 and the U-shaped delivery pipe 2 are interconnected through an additional U-shaped butt joint pipe to form a group of flat delivery pipes. As the coolant enters the U-shaped delivery pipe 1, the coolant will be transported in the flat pipes to guide the heat generated inside the shell into the coolant. The coolant returns to the liquid storage tank along the U-shaped delivery pipe 2. As the coolant circulates, the heat inside the shell is dissipated, so that the components inside the shell can operate more stably.

[0024] The present invention provides a railway passenger safety screen door anti-pinch system, which has the following beneficial effects:

[0025] 1.

[0026] 2. Heat management and heat dissipation of the present invention: the system contains a heat exchange and dissipation component, and the coolant is circulated by a small delivery pump. The coolant circulates in the U-shaped delivery pipe, effectively guiding the heat generated inside the shell into the coolant, and then returns to the storage tank through the U-shaped delivery pipe 2, thereby achieving effective heat dissipation and stabilizing the operating temperature of components. The design of the cooling system not only helps to maintain the stable operating temperature of the equipment, but also can extend the life of the equipment and reduce the failure rate, improve the safety and reliability of the equipment, and the structural design of the U-shaped delivery pipe and the butt pipe enables the coolant to form an effective circulation path in the pipe, thereby maximizing the heat dissipation efficiency and energy efficiency.
