DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. If there is a description of "first", "second" and the like in the embodiments of the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features indicated or the number of the technical features indicated. Therefore, the features with "first" and "second" can explicitly or implicitly include at least one of the features.

[0044] It can be understood that, with the rapid development of automatic driving technology, the system stability of the automatic driving robot mainboard is increasingly becoming a key technical bottleneck. At present, the automatic driving robot mainboard mainly adopts a general industrial control mainboard or a modified server mainboard scheme, and such a scheme has the core technical problem of insufficient system reliability. Specifically, the existing scheme has defects in interface design, heat dissipation system, management function and spatial layout and the like, which are interrelated and jointly affect the stable operation of the system.

[0045] For example, the interface stability, the existing mainboards generally adopt standard USB and RJ45 and other consumer interfaces. Under the continuous vibration in the industrial environment, the connection terminals of these interfaces are prone to displacement, resulting in signal transmission interruption. At the same time, the power supply capacity of the USB interface is limited, which is difficult to meet the current demand of industrial-grade sensors at peak work. This interface instability is related to the design of the heat dissipation system: in order to ensure sufficient air flow rate, the air duct opening often occupies a large amount of chassis surface area, resulting in insufficient chassis protection level, which further aggravates the dust accumulation at the interface position.

[0046] When the system operating temperature rises, the coupling effect of these problems is more obvious. Under high temperature working conditions, the mainboard chip is prone to over-temperature, and the existing mainboard adopts consumer-grade chip with limited operating temperature range. High temperature not only directly affects the performance of the chip, but also accelerates the aging of the interface material. At the same time, due to the insufficient utilization rate of PCB layout, the device distribution is not compact enough, resulting in redundant design of the heat dissipation channel, which further reduces the heat dissipation efficiency.

[0047] More importantly, the existing mainboard lacks a remote management mechanism at the hardware level, and cannot effectively deal with system failures caused by the superposition of the above problems. When the autonomous driving robot has startup abnormity or system crash in extreme temperature environment, it is impossible to diagnose and recover the system through remote means, which significantly prolongs the fault recovery time. At the same time, the system lacks anti-interference ability, which is difficult to meet the anti-static requirements of industrial environment, and this insufficient electrical performance further increases the system instability.

[0048] Therefore, the present application proposes an autonomous driving robot mainboard, which aims to solve the problem of how to balance the stability and reliability of the autonomous driving robot mainboard.

[0049] Please refer to Figure 1 , Figure 1 is a module connection diagram of the first embodiment of the autonomous driving robot mainboard of the present application.

[0059] In the application, the Type-E interface has a solid mechanical locking structure, which can effectively prevent the interface from loosening under complex working conditions; the wafer interface selects an industrial-grade connector, which can greatly improve the mechanical strength and stability of the connection, thereby improving the stability of the mainboard through the Type-E interface and the wafer interface. Secondly, the server-level BMCAST 2500 chip used in the application has a built-in Super IO function and has a dual-channel redundant design, which, in combination with the hardware monitoring circuit 40, can construct a complete system monitoring and remote management system, thereby improving the reliability of the mainboard. It can be seen that the application can effectively improve the reliability and stability of the automatic driving robot mainboard.

[0060] In addition, in view of the poor heat dissipation capacity of the traditional mainboard, the application can place the memory slot on the front surface and the CPU 10 on the back surface; at the same time, the heat generating devices (the BMC chip 30, the PCH chip 20 and other power devices) and the CPU 10 are kept on the same surface, and no other materials with high heat dissipation are placed on the back surface, so as to facilitate heat dissipation; the outermost layer is a large-area water cooling plate which is tightly combined with the back plate of the case shell, thereby realizing efficient heat dissipation by using a water cooling system and achieving the effect of improving the heat dissipation efficiency while maintaining a small size.
