[0002] With the rapid development of my country's economy, rail transit has become an indispensable means of transportation for modern people. Drivers' fatigue driving and distracted attention not only endanger the personal and property safety of the driver himself and the people in the car, but also endanger road safety and the life and property safety of others.

[0003] The driver driving status intelligent analysis system is mainly used in rail transportation fields such as subways and high-speed railways. In these scenarios, the driver's behavior and status have a vital impact on the safe operation of the train. Through the application of this system, comprehensive monitoring and analysis of the driver's behavior can be achieved, effectively improving the safety and reliability of train operation, and providing passengers with a more comfortable and safe travel experience. For example, the Chinese patent CN117690256A of the prior art discloses a driver monitoring system and method, which mainly includes a host terminal, a DMSECU, a communication module, a driving behavior monitoring module, a fatigue status monitoring module, a Bluetooth bracelet, an alarm component and a broadcast module.

DETAILED DESCRIPTION

[0024] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides a main box of a train driver driving status monitoring system, comprising a top shell 1 and a bottom shell 2 that can be detachably connected. The top shell 1 and the bottom shell 2 have a regular appearance after being assembled, and can form a standard 1U chassis, which can meet international chassis standards and can be installed on any 19-inch cabinet.

[0027] Specifically, the top shell 1 includes a top panel 11, a rear panel 12, and a pair of side panels 13 distributed on the left and right sides, which are enclosed in a rectangular frame. A front connecting plate 14 is arranged on the front side of the top panel 11. The heights of the rear panel 12 and the side panels 13 are consistent, and the heights of the rear panel 12 and the side panels 13 are greater than the height of the front connecting plate 14. In this way, the bottom and the front side of the top shell 1 are open.

[0028] Specifically, the bottom shell 2 includes a bottom panel 21 and a side expansion panel 22 that are integrally formed and vertically arranged, so that the bottom panel 21 and the side expansion panel 22 cover the bottom and side openings of the top shell 1 respectively.

[0029] Among them, the top shell 1 and the bottom shell 2 are both made of full metal materials, such as aluminum sheet metal materials, which makes the main box lighter and ensures the reliability and durability of the main box.

[0030] Specifically, the surfaces of the top panel 11, the side panel 13, and the bottom panel 21 are all formed with a large area of ​​heat dissipation grille 3, forming double-sided air convection heat dissipation to improve heat dissipation efficiency. In particular, dustproof cotton (not clearly shown in the figure) is adhered to the inner side of the heat dissipation grille 3 on the top panel 11. The dustproof cotton can prevent dust from entering the inside of the main box from the top of the main box to avoid poor contact or short circuit of components. The inner side of the bottom panel 21 is provided with a mainboard 4 and a power module 5 for electrical connection. The mainboard 4 and the power module 5 and other hardware are integrated in the main box to improve the degree of integration. The surface of the side expansion panel 22 has a plurality of plug-in interfaces corresponding to the ports on the mainboard 4, and a plurality of functional ports corresponding to the power module 5. It should be noted that what is actually to be protected in this application is a hardware structure layout design of a main box, so no more specific explanation is given about the model and design of the mainboard and the power module, which will not affect other technicians' understanding of the technical solution of this embodiment.

[0031] In the specific implementation, the side of the bottom panel 21 is also bent to form a rear fold 23 and a pair of side folds 24 distributed on the left and right. The rear fold 23 and the inner wall of the rear panel 12, the side fold 24 and the inner wall of the side panel 13, and the front connecting plate 14 and the inner wall of the side extension panel 22 are all in contact and are fixedly connected by screws. In this way, the top shell and the bottom shell are fixed by overlapping rivet screws, which is easy to disassemble and convenient to install and maintain.

[0032] Furthermore, a plurality of spaced connecting ears 241 are formed on the side fold 24 extending vertically upward, and a plurality of abutting portions 131 are provided on the surface of the side panel 13 corresponding to the connecting ears 241, and screw holes 242 (132) are formed on the connecting ears 241 and the abutting portions 131. In this way, the connection strength between the side fold and the side panel is enhanced through the cooperation between the connecting ears and the abutting portions.

[0033] In a specific implementation, the plurality of plug-in interfaces include a USB interface installation port 221, an aviation interface installation port 222, and a DB9 interface installation port 223. The USB interface, aviation interface, and DB9 interface are installed through the above-mentioned installation ports, and these interfaces are all connected to the mainboard in a circuit, so that different data lines can be connected through the side expansion panel, thereby connecting different functional modules to improve data transmission security and stability.

[0034] In addition, multiple functional ports include a system indicator light installation port 224, a power indicator light installation port 225, a grounding wire post socket 226, and a power input socket 227. The system indicator light, power indicator light, grounding wire post, and plug-in terminal are installed through these installation ports, and are all electrically connected to the power module. The power supply voltage DC110V of the electric locomotive is connected to the power module through the power input socket. The power module converts the DC110V voltage into the power supply of the DC24V working voltage required by the mainboard. The system indicator light installation port and the power indicator light installation port are used to install the system indicator light and the power indicator light. In subsequent actual work, when the connected electric locomotive power supply DC110V is normal, the power indicator light is green, and when it is abnormal, the power indicator light is red; when the output 24V working power supply for the host and external devices is normal, the system indicator light is green, and when it is abnormal, the system indicator light is red.

[0035] In a specific embodiment, the length of the side expansion panel 22 is greater than the length of the rear panel 12, and mounting holes 228 are provided on both sides of the side expansion panel 22. By inserting screws into the provided mounting holes, the main box can be fixedly connected to any 19-inch cabinet by screws, which is convenient for installation.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
