Problems solved by technology

[0004] The current Loongson-based circuit boards on the market have different application methods due to different technical requirements, interface types, and quantities at the application site. The interfaces provided by the existing Loongson-based core boards cannot meet the needs of users. To adapt to the needs of more system products with different functions, the flexibility is poor, and the overall stability is poor, so it is necessary to improve it

Abstract

The invention discloses a domestic control mainboard based on Loongson 2K. The domestic control mainboard comprises a Loongson 2K chip, a video bus conversion module, a format conversion module, a CAN transceiver, a level conversion module, an audio conversion module, a network chip and a memory used for information storage, which are installed on a PCB. A plurality of blind holes used for connecting a first conductive pattern layer and a second conductive pattern layer are formed in a second dielectric layer, a heat dissipation block with clamping blocks at the two side ends is embedded into a mounting groove of an aluminum substrate, and the clamping blocks of the heat dissipation block are embedded into clamping grooves of the mounting groove; and a plastic sleeve with a through hole allowing a bolt to be embedded in is embedded in a mounting through hole, the upper portion, located above the aluminum substrate, of a plastic sleeve is provided with a wide-opening extension portion, the lower portion, located below the aluminum substrate, of the plastic sleeve is provided with an outer protruding portion, and the blind hole is composed of an arc hole and a conical hole communicated with the bottom of an arc hole. According to the invention, the resistance is reduced, the reliability is improved, efficient real-time acquisition, processing and transmission of signals and battery management are also realized, and the functions of products are conveniently expanded.

Description

technical field [0001] The invention relates to a motherboard and belongs to the technical field of computers. Background technique [0002] With the rapid development of computer technology, the embedded development platform has been more and more widely used in industrial automation control. Because the industrial control circuit board integrates the core general functions, an industrial control circuit board is equipped with different backplanes, so as to realize system chips with different functions in different fields. [0003] The chip is a highly integrated system chip designed for safe and suitable computers. The chip integrates fixed-point processors, floating-point processors, streaming media processing, graphics and image processing functions, south bridge and north bridge supporting chipset functions, and some I / O functions. . Users can use the Loongson chip to develop the core board of the product. [0004] The current Loongson-based circuit boards on the mar...
