A system and method for realizing gsm module control in single chip microcomputer

Abstract

The invention discloses a system for realizing GSM module controlling in a single-chip microcomputer. The system comprises a GSM task scheduling layer, a task processing and canceling layer, a task executing layer, a function packaging layer, an underlayer driving layer and a global variable layer, wherein the GSM task scheduling layer, the task processing and canceling layer, the task executing layer, the function packaging layer and the underlayer driving layer are successively connected, and furthermore are connected with the global variable layer. According to the system, through a software architecture which comprises the five layers and the global variable layer, a GSM task is divided into a function sequence of a GSM module; one function packaging function is executed in each calling a task execution function; the function packaging function detects a response in a synchronization manner for an AT command with the response in short time through asynchronous controlling; the response can be generated in a relatively quick manner; and the response of the AT command with relatively long response time is detected in a asynchronous manner, thereby reducing waiting time for the response and reducing system power consumption.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an embedded system for realizing low power consumption control of a GSM wireless communication module on a single-chip microcomputer and a working method thereof, more specifically, to realizing low power consumption control of a GSM module with an embedded software framework. Background technique [0002] GSM (Global System for Mobile Communication) technology is well known to the public, the core module of which is the GSM wireless communication module, which refers to the GSM standard, with the ability to send text messages, voice calls, GPRS data transmission, etc. A software module for all basic functions of a GSM network, also referred to as a GSM module. [0003] Most smart hardware products on the market are equipped with communication modules. According to their needs, WIFI modules, Bluetooth modules, and GSM modules may be selected. Among them, the GSM mod...

Problems solved by technology

This way of programming is relatively simple, but there are certain defects: the return time of the time-consuming AT command is not fixed, if the time-out time is set too short, the command failure rate will be high, if the time-out time is set too long, the system will block for too long, Affect system processing speed

In the data transparent transmission architecture, the GSM module is turned on for too long, so the power consumption is high. In addition, because the GSM module is continuously turned on, functions other than GPRS data transmission cannot be used

In the synchronous control architecture, it is difficult to properly set the timeout period of long commands. If it is too high, the system will be blocked for a long time. If it is too low, the command success rate will be low, and the existence of system blocking will definitely lead to a decline in user experience. Further, In the synchronous control logic, the main program code and the GSM module control code are highly coupled, which leads to the fact that once the GSM module is replaced, the main program code must be modified accordingly, greatly increasing the workload of developers
