Embodiment Construction

[0021] Combine below figure 1 , figure 2 The online software upgrade method of the present invention will be further described with the embodiments.

[0022] Such as figure 2 As shown, the hardware part is based on Intel 386 TM The EX embedded microprocessor is used as the CPU, and is equipped with basic circuits such as EPROM, FLASH EPROM, RAM, WATCHDOG, etc., as well as functional units and communication units such as telemetry, remote signaling, and remote control. Among them, EPROM stores the factory program, FLASH EPROM stores configuration information and upgrade program, WATCHDOG monitors the running status of the program, and the communication unit is responsible for contacting the monitoring center and accepting the upgrade program and various commands sent by the monitoring center.

[0023] In addition to ensuring basic functions such as reliable download and correct storage of the upgrade program, the software part also needs to monitor the running status of t...

Abstract

The invention discloses a method for software online upgrading comprising, marking-out an area in the allocable zone of the terminal module for storing download program supervisory structure variable, transmitting the upgrading program to terminal module and storing it in the allocable zone, assigning value for the member variable of the download program supervisory structure variables, and storing it into the allocable zone, halting the operation to watchdog, reseting CPU after a preset-time to restart the terminal module, reading the download program supervisory structure variable which has been assigned an initial value and determining the program flow path based on the value of its structure member. The invention can improve working efficiency.

Description

technical field [0001] The invention relates to the field of software downloading, in particular to a software downloading method in the field of power equipment and environment centralized monitoring. Background technique [0002] The power equipment and environment centralized monitoring system is used for remote measurement, remote signaling and remote control of various parameters, images, sounds, etc. Monitor its operating parameters in real time, diagnose and deal with faults, record and analyze relevant data, so as to realize a computer control system for centralized monitoring and centralized maintenance of equipment with fewer or unattended communication bureaus (stations). [0003] The power equipment and environment centralized monitoring system mostly adopts distributed computer control system, which is generally divided into local network monitoring center, county-level monitoring station, remote controlled station monitoring unit and remote monitoring terminal ...
