| In order to meet the requirement of mobile remote monitoring during the safety production of coal in coal mine, based on the fixed network remote monitoring system and using the data platform of fixed network remote monitoring system, a mobile synthetical monitoring system in safty production of coal mine which is based on smart terminal is designed in this paper.Current situation and the developmental trend of monitoring system of coal mine and mobile service which are in and out of our country are analyzed fist. C/S structure, TCP and SOCKET communication which are necessary core technology are analyzed. The whole software module and physical structure are proposed. C/S is chosen to be the basic structure of the system. Developer platforms of both the server and mobile handset are chosen and put up. Database is chosen and function is designed in server. Besides that, the function of monitoring real time data extracting, data packaging and data transmission are designed and implemented in detail. The whole function of mobile handset is designed and the function of real-time monitoring in safety production is designed and implemented in detail which includes interface designing, identification and permission, transmission, data processing, synthetical and real time monitoring show. Finally, according to the fundamental rule of software test, both the test on simulator and real mobile phone are implemented. The test shows that the system not only has a good human-computer interface but also operated conveniently. The system is very reliable and stable. After a week's running, every function is running well. The system can be used to monitor the real time data in down hole of coal mine. |
