Description

Technical Field

[0001] This utility model relates to the field of high-speed train safety monitoring technology, specifically to a side-mounted folding protective door with electromagnetic shielding and intelligent monitoring functions for onboard equipment. Background Technology

[0002] With the increasing number of operating high-speed trains, the safety and efficiency of the maintenance and management of train control equipment will directly affect and restrict the safe and efficient operation of railways.

[0003] Environmental interference causing equipment malfunctions in high-speed rail train control systems has long been a major challenge for electrical engineers. When faced with problems such as surges, electromagnetic radiation, alternating humidity and heat, and static electricity in the ATP system, the lack of onboard equipment environmental detection methods makes it impossible to confirm the existence of such interference or whether it falls within the ATP system's interference immunity range. Consequently, electrical engineers cannot quickly and easily locate the problem, eliminate the fault, and restore equipment operation, thus affecting the efficient operation of high-speed rail.

[0004] The existing solution involves replacing the relevant equipment and cables in the system one by one with spare parts. After each component is replaced, the machine is started to check if the fault has been eliminated. This process is repeated until the fault disappears. This troubleshooting method wastes a lot of time, manpower, and resources on disassembling and assembling equipment and waiting for the equipment to start up and perform self-tests. However, the root cause of the fault is not truly quantified and identified, leaving hidden dangers for the later use of the equipment.

[0005] Therefore, we propose a side-mounted folding protective door with electromagnetic shielding and intelligent monitoring functions for vehicle-mounted equipment, which effectively solves the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a side-mounted folding protective door with electromagnetic shielding and intelligent monitoring functions for vehicle-mounted equipment, thereby achieving safety monitoring.

[0007] This utility model provides a side-mounted folding protective door for vehicle-mounted equipment with electromagnetic shielding and intelligent monitoring functions, comprising: a main door body, the main door body including a glass shielding door, a cabinet, and a mounting frame; the mounting frame is fixedly mounted on the cabinet; the glass shielding door is mounted on the cabinet and is used to open and close the cabinet; the mounting frame includes a slide rail and a cabinet door guide block, one end of the cabinet door guide block is fixedly mounted on the cabinet, and the other end of the cabinet door guide block is slidably mounted on the slide rail; and functional components, the functional components being disposed within the main door body, the functional components including a dehumidifier, a display, a temperature and humidity sensor, a control mainboard, and an electromagnetic field acquisition device; at least one of the dehumidifiers is disposed within the cabinet; the display is detachably mounted on the glass shielding door and electrically connected to one end of the control mainboard; the other end of the control mainboard is electrically connected to the temperature and humidity sensor and the electromagnetic field acquisition device respectively.

[0008] Furthermore, the dehumidification component includes a fan, which is mounted on the glass shielding door and located above the display unit. The fan has four locations. In practical use, when the temperature inside the cabinet exceeds 65 degrees Celsius or the humidity exceeds 70%, the exhaust mode is activated. If dehumidification is ineffective after activation, a reminder is given to replace the desiccant.

[0009] Furthermore, the dehumidifying component includes a desiccant, and is fixedly installed inside the cabinet using cable ties. In practical applications, a square silica gel desiccant with mounting holes around its perimeter is selected and fixed using cable ties.

[0010] Furthermore, it also includes a power conversion module and a battery; the battery is electrically connected to the power conversion module. In practical applications, the battery serves as the main power supply for the entire device, and the power conversion module converts the power to effectively power each component. In actual operation, a 24V lithium battery is used for power supply, with a battery capacity not exceeding 10000mA / h; this is used to obtain the temperature inside the cabinet and the average power consumption of the protective door through testing.

[0011] Furthermore, the temperature and humidity component includes a temperature and humidity sensor. Three humidity sensors are located at the bottom, middle, and top of the cabinet. In practical applications, the purpose of this design is to periodically monitor the temperature and humidity inside the cabinet. The three-point detection system (bottom, middle, and top) allows for real-time monitoring of temperature and humidity changes within the cabinet. Simultaneously, it detects the ATP system's fault status, monitors changes in the cabinet's module indicator lights, and, combined with environmental and equipment operating conditions, analyzes the causes of cabinet malfunctions.

[0012] Furthermore, it also includes a gyroscope, which is installed inside the cabinet. In practical applications, the gyroscope detects the train's operating status—acceleration, stillness, deceleration, and constant speed—based on the train's acceleration, deceleration, and duration. This allows for the diagnosis of the equipment's operational and sleep states.

[0013] Furthermore, the electromagnetic field acquisition device also includes a detection coil, which is used to detect the induced voltage and signal frequency range. In practical operation, this design can effectively detect voltage and electromagnetic signals, thereby facilitating the implementation of diagnostic equipment.

[0014] Furthermore, it also includes a door-close sensor, which is used for door opening detection. In practical applications, the designer uses a proximity sensor to confirm whether the cabinet door has been opened and records the opening time for the door opening / closing detection function.

[0015] As can be seen from the above technical solution, the beneficial effects of the side-mounted folding protective door with electromagnetic shielding and intelligent monitoring functions provided by this utility model are as follows: (1) In practical applications, the display device used is an integrated data acquisition and display device, which consists of a seven-inch display screen and a data acquisition motherboard. Using a seven-inch display screen and a data acquisition motherboard, it can display the real-time temperature and humidity inside the cabinet, early warning information, etc., and query historical data at the same time. The storage capacity is no more than 60 days.

[0016] (2) The control motherboard communicates with three temperature and humidity sensors via MODBUS to obtain the temperature and humidity of the set point, and determines whether to turn on the fan based on the temperature and humidity values; the functional components can effectively achieve overall detection.
