LWD Data Remote Transmission System Based On GPRS

With rapid development of automatic control and network techniques, network-based LWD Data Remote Transmission is becoming an investigating hotspot in the oil industry. At present, the way of wired communication to transmit data has been mostly used in the field of industry, though very economical and practical, wired data transmission has limited its application prospects to a large extent. In order to make the remote transmission more flexible and convenient, in this paper, GPRS technology has been selected to transmit the remote data. This thesis is researching on the system of LWD Data Remote Transmission, based on GPRS, integrates of traditional computer, modern Internet and GPRS technology. It has many merits, such a multiple functions, low cost, well real time capability and high reliability. It is also convenient to operate, easy to install, maintain and upgrade.After analyzing present researches and comparing the current means on remote wireless monitoring systems of elevators, integrating traditional modal of remote monitoring system, we advance LWD Data Remote Transmission System based on GPRS .Through compared the present ways of the wireless data transmission, GPRS has been chose as to transmit the remote data. Firstly, explaining the GPRS in detail, including its system frame and its network feature. Then, designing the data communication system, mainly analyzing the form-net project and the communication scheme of the system and the function of the constitution, besides, analyzing the system's security .This thesis designs and develops the scheme of LWD Data Long-rang Transmission System Based on GPRS in detail, emphases on system structure, system constitutes and system work process, and also explains the system constitutes'function and design details. Then it narrates the design of software process to client and center monitor, and introduces the detail of function module development and database design. Finally, the development flow of LWD Data Long-rang Transmission System Based on GPRS was summarized.
