Single-chip microcomputer device with power failure prevention function

Abstract

The invention discloses a single-chip microcomputer device with a power failure prevention function. The device comprises a box body, a partition plate is fixedly connected between the left side and the right side of the inner wall of the box body, the top of the partition plate is fixedly connected with a bread board, the bread board is provided with a single-chip microcomputer chip, the top of the bread board is provided with a fixing device, the left side of the bottom of the inner wall of the box body is fixedly connected with a control box, and the right side of the bottom of the inner wall of the box body is fixedly connected with a standby power supply. The invention relates to the technical field of single-chip microcomputers. According to the single-chip microcomputer device with the power failure prevention function, the standby power supply can be automatically turned on to supply power to a single-chip microcomputer control module under the power failure condition, the power failure prevention function is achieved, the single-chip microcomputer control module can continue to work when the power supply is powered off, the single-chip microcomputer chip is limited through a limiting block, the single-chip microcomputer chip cannot be loosened, the single-chip microcomputer module is stable in contact with a circuit, poor contact is avoided, and loss caused by the fact that the single-chip microcomputer module is suddenly powered off and cannot work is avoided.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputers, in particular to a single-chip microcomputer device with the function of preventing power failure. Background technique [0002] Single-chip microcomputer is a kind of integrated circuit chip, which adopts VLSI 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 systems, timers / counters, etc. Functions (may also include display drive circuit, pulse width modulation circuit, analog multiplexer, A / D converter and other circuits) integrated into a silicon chip to form a small and complete microcomputer system, widely used in the field of industrial control application. From the 1980s, from the 4-bit and 8-bit single-chip microcomputers at that time, to the current 300M high-speed single-chip microcomputers. [0003] Single-chip microcomputers are widely used in the fiel...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a single-chip microcomputer device with the function of preventing power failure, which solves the problem that the existing single-chip microcomputer control module cannot operate when the power supply is suddenly cut off due to external factors, which may cause certain The loss of the single-chip microcomputer is generally inserted into the breadboard or circuit board, and it is easy to loosen, resulting in power failure of the single-chip microcomputer and failure of the control module. Some of them have the problem of limiting the position of the single-chip microcomputer, but the operation is more troublesome and inconvenient to use.
