Embodiment Construction

[0033] 1. Program file description

[0034] Repeater equipment monitoring software is developed based on ATmega128 microcontroller. ATmega128 microcontroller program is divided into two parts: Bootloader program and application program. Locate the Bootloader program at address 0x1F000 by modifying the Makefile of the Bootloader program. The application program is located at address 0x00000 by default.

[0035] The chip program must be downloaded with the programmer for the first time, and then the remote upgrade function can be realized. The programming program file is the merged file of the Bootloader program and the Hex file of the application program, and the upgrade program file is the Binary file of the application program. During the remote upgrade, only the application program area is refreshed, and the Bootloader program area remains unchanged. By modifying the Makefile file, select whether the compiled output file is in Hex format or Binary format. The size of the...

Abstract

The invention relates to the performance optimization of repeater equipment in communication field. The remote-updating and version-switching method of the repeater equipment embedded software comprises the following steps: 1) an OMC or OMT command is received in real time, if the command is an update command, go forward to step 2; if the command is a version-switching command, skip to step 5; and if the command is not received, skip to step 6; 2) an update document data packet is received from the OMC or OMT, and the received update document data packet is stored in a download process-memorizing region; 3) a download process code in the download process-storing region is programmed into the application process region of a singlechip; 4) the code data of the application process region is read byte by byte and written into a new version process-storing region; 5) when a currently running process is a new version process, a process code in an old version process-storing region is programmed into the application process region of the singlechip, otherwise, the process code in the new version process-storing region is programmed into the application process region of the singlechip; and 6. the monitor mode of the application process is executed. The method can realize the remote updating and the switching between the new process version and the old process version.

Description

technical field [0001] The invention relates to performance optimization of repeater equipment in the communication field, in particular to a method for remote upgrading and version switching of embedded software of repeater equipment. Background technique [0002] The monitoring software running on the repeater monitoring system needs to be upgraded. Since the installation locations of the repeaters are relatively scattered, and generally the installation locations are relatively remote, on-site upgrades are troublesome. Therefore, it is necessary to remotely upgrade the monitoring software on the repeater monitoring system, that is, in the monitoring center, for the selected repeater, upgrade the monitoring software running on the monitoring system through remote downloading, so as to realize timely New monitoring functions or address software defects, reducing maintenance costs. Remote upgrade requires high reliability, high success rate, and high efficiency. [0003] ...
