Abstract

The present invention relates to the upgrading process and monitoring circuit for 8051 monolithic computer system. The upgrading process includes the following steps: receiving the newest upgrading program via DSLAM equipment network management and external data interface, setting in local buffering memory and sending on-line upgrading command; power-on to start the 8051 monolithic computer system, and performing proper mode switching with some control pins of the 8051 monolithic computer system and peripheral logic control circuit to realize the on-line upgrading of the system via the cooperation of the different work modes. The on-line upgrading may be completed without needing the maintenance worker to attend site, being fast and saving in time and labor.

Description

technical field [0001] The invention relates to an 8051 single-chip microcomputer system upgrading method and a monitoring circuit. Background technique [0002] The 8051 single-chip microcomputer has the characteristics of high cost performance, flexible functions, easy man-machine dialogue and good data processing capabilities, and has been widely used in various telecommunication system equipment. In order to continuously improve the performance of equipment and meet the diverse needs of users, the continuous upgrading of telecommunications system equipment is essential. In some cases, the upgrading of the control software and control parameters in the system needs to be updated. The existing technology usually uses circuit Remove the data memory (EPROM, EEPROM, etc.) on the board, and then use a dedicated programmer to download new software and parameters to the data memory or directly update these memories. This method requires professional maintenance personnel to go ...
