Abstract

The invention particularly discloses a software system based on a GPRS monitoring terminal. The software system is composed of a bottom layer hardware driving program, an embedded operating system and a multi-task application program, wherein the multi-task application program is implemented on the basis of a multi-task design mode; a plurality of tasks comprise a starting task, a Modem serial port receiving task, a GPRS scheduling task, a data analysis conversion task, a GPRS link establishment and maintenance task, a system monitoring alarm task, and an equipment data acquisition, storage and uploading task; a state machine of the GPRS link establishment and maintenance task comprises a state conversion process; a multi-task software watchdog is implemented by implementing the multi-task application program. The software system based on the GPRS monitoring terminal, which is high in reliability, can normally operate in severe application environments such as photovoltaic power stations and wind power plants.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and specifically discloses a software system based on a GPRS monitoring terminal. Background technique [0002] In harsh industrial applications such as photovoltaic power plants and wind farms, in order to ensure the reliable operation of on-site devices, remote monitoring of these devices is required. GPRS is one of the most important data transmission methods in IoT applications, and has been widely used in industrial automation, smart grid, smart transportation, smart home, logistics, hydrology, meteorology and other industries. Using GPRS technology can easily build a remote intelligent monitoring system for field equipment to meet the needs of users. On the one hand, equipment manufacturers can easily realize long-term monitoring and remote upgrading of equipment operation status through this monitoring system, so as to realize remote maintenance of equipment, continuously i...
