Microcomputer operation program backing-up device in electronic product

Abstract

The invention provides a microcomputer operating program backup device in electronic products, comprising: a microcomputer used as a local area network server, a main memory used to store the operating programs and communication protocols of each electronic product in the local area network, and a device used to connect each electronic product The serial interface, the auxiliary storage for storing the backup operation program and the communication protocol of each electronic product in the local area network, the multiplexer and the changeover switch; the beneficial effects of the present invention are: simple structure and convenient operation. Using a simple switch operation to restore the operating program, the communication protocol of the household electronic product can be changed without damaging the memory, thereby improving the stability of the LAN system and reducing the cost of replacement parts and repairs.

Description

technical field [0001] The invention relates to a microcomputer operating program backup device, in particular to a microcomputer operating program backup device in electronic products. Background technique [0002] At present, as more and more household electronic products generally adopt microcomputer control, the control of household electronic products is developing in the direction of automation and networking. In the initial stage of automatic control of household electronic products, a certain household electronic product is generally controlled by telephone or infrared remote control. In recent years, people have connected various household electronic products at home into a network (local area network), and can control multiple household electronic products in the local area network through a network server, realizing networked control of household electronic products. [0003] Such as figure 1 As shown, the general household electronic product local area network ...

AI Technical Summary

Problems solved by technology

This requires installing a new communication protocol in the memory 11, and installing a new communication protocol in the memory 11 will cause the operating program currently in use to change, and the operating program currently in use will be destroyed, resulting in a certain Some home electronics are unresponsive or functioning incorrectly

When the problem is serious, it may even cause damage to the hardware in the microcomputer 10 or memory 11, and sometimes the main board of the microcomputer 10 has to be replaced, which brings time and economical losses to the user.
