Abstract

With the development of communication technology and computer technology, remote monitoring system is becoming more and more important in industry. It can be used to realize real-time remote monitoring in unattended workshop or dangerous areas. In the field of wireless communications, because of having a series of virtues such as good real-time performance, fast data transmission, low cost and so on, GPRS network is widely used in the remote wireless monitoring system.

The main purpose of the paper is to develop an embedded remote wireless monitoring system based on GPRS, which can be used in the mobile harbor cranes. The principle of key technology and the communication protocol in system is introduced first. Then the whole structure will be involved, which contains hardware and software solution. On the hardware, the system uses STM32F407 as the core control chip and SIM300 which integrates TCP/IP protocol as GPRS communication module. Then the paper introduces the CANopen interface circuit, power circuit, display driver circuit and the standby interface circuit. The software is written to realize each module functions including the collection, transmission and reception of data. Finally, the company can use PC software on the remote monitoring computer to display data from the GPRS network transmission.
