Single-chip microcomputer practical training platform

Abstract

The invention provides a single-chip microcomputer practical training platform. The single-chip microcomputer practical training platform structurally comprises a jack, a panel, a water collecting tank, a tool box, a supporting frame and a workbench, wherein the jack is fixedly embedded in the outer surface of the front end of the panel, the lower end of the panel is fixedly embedded in the rear end of the workbench, the inner end of the water collecting tank is fixedly embedded in the outer side of the lower end of the panel, the outer side of the tool box is connected to the inner side of the supporting frame in a clamped mode, and the lower end of the workbench is welded to the upper end of the supporting frame; the jack comprises a connecting wall, a flow collecting disc, a contact head and a water stop plate, the inner side of the connecting wall is connected with the outer side of the flow collecting disc in a clamped mode, the contact head is arranged on the inner side of the connecting wall, and the outer side of the water stop plate is fixedly embedded in the inner side of the lower end of the connecting wall; when the outer surface of the panel is wetted, water drops are formed and slide downwards, and the water drops enter the flow collecting tank to be collected; when water drops onto a waterproof plate, the water is absorbed through a concave arc of a water absorption block on a telescopic press, so that the phenomenon of electric leakage caused when the water drops into the contact head is prevented; and when a plug is inserted, an extrusion block is pushed to enable a telescopic plate to contract.

Description

technical field [0001] The invention belongs to the field of processing equipment containing a single-chip microcomputer, and more specifically relates to a single-chip microcomputer training platform. Background technique [0002] Single-chip microcomputer is a kind of integrated circuit chip, which adopts ultra-large-scale integrated circuit technology to combine central processing unit CPU with data processing capability, random access memory RAM, read-only memory ROM, various I / O ports and interrupt system, timer / Functions such as counters are integrated into a piece of silicon, thereby forming a small and complete microcomputer system, which is widely used in the field of industrial control. [0003] Based on the above description, the inventors found that the existing single-chip training platform mainly has the following deficiencies, such as: [0004] After spring every year in the south, due to the low surface temperature of the electric board on the test bench, c...

AI Technical Summary

Problems solved by technology

[0004] After spring every year in the south, due to the low surface temperature of the electric board on the test bench, condensation will form on the surface after contact with high-concentration moisture from the outside to produce water droplets, and the electric board is usually installed vertically or at an oblique angle of about 20° , and there are many power jacks and information conduction holes on the electric board. When the water drops freely slide down into the jack through accumulation, the metal sheet in the jack is in contact with the water. If the machine is turned on again, A large amount of flammable hydrogen gas is generated due to the conduction and heat between the metal sheet and the water, which leads to electric leakage or explosive combustion when the test bench tests the single-chip microcomputer
