Exploiture Of Wireless Transmission System Of Parameters In Drilling

It is a large waste of manpower and material resources if the drilling data acquisition still depends on the traditional wire transmission with the development of microelectronic technique,which make the wireless product integrative and modularization. Wireless transmission of drilling data between the field and the workshop can make the measurement simplified and realize long-distance watch and make it convenient to monitor in fieldwork.Based on the reference of vast correlative papers , fully analysis of modern wireless transmission technology and principle,and research of advanced wireless data transmission products in the world, and the reference of modern sensing technology and data acquisition technology, wireless data transmission module SA68F49DL is selected, which satisfies the requirement of the needed system.Wireless transmission between the data acquisition and the upper computer is realized through the substitution of a couple of wireless data transmission modules for cables. As the remote forepart, the data acquisition unit is composed of advanced sensor and singleclip. The upper computer software of wireless data acquisition system is written in VB and runs under Windows operation system, which has the ability of correspondence with wireless data transmission module data signal serial port. The upper computer corresponds with wireless data module through RS-232 serial port, and fulfills the realtime acquisition, display and saving of data signals. As the dialogue window of the operator and the computer, the software can select acquisition channels and frequency. In repetitious experiments, the whole system obtained satisfied result.The application of the system will make the field supervising more convenient.
