| With the rapid development of communication networks in recent years,wireless monitor system based the GSM/GPRS becomes the most widespread application in the current long-distance wireless monitoring fields. In the other hand, the multi-CPU monitoring system, which is connected by single-chipped computer and PC machine through serial interface is widely used in the fields of industry and data monitoring.The communication way of these systems is always cable modem,radio station and so on .But their inherent fault limits the fields in which these systems are used.This article mainly designed and has realized based on monolithic integrated circuit's authentication, the demonstration and the alarm system Through software and hardware union design,we completes one kind of practical long-distance entrance guard supervisory system.And through the software programming, controlled the monolithic integrated circuit to realize the identification authentication and the warning function, achieved has carried on the recognition control to the visitor status the goal.Firstly, the dissertation introducest he background,the present situation and significance of the research. Then, the author presents the solution to the wireless monitor system based on GSM in detail, which is combined with the characteristics of wireless monitoring system. It also gives details of the controller design using the design theory of embedded system. After the system design being finished, the author explains how to implement the hardware and software of the wireless monitoring system. The characters of the wireless monitoring system are as follows:1. Multiplex function.A pplication for data transmission,data acquiring and long-distance monitoring etc.2. Low cost.The cost of controller is lower than the wireless monitoring system based on other communication networks.3. Multiplicity for input and output.The system can be implemented via software module and hardware module based on the industrial field need. |
