【Abstract】 An information module in field equipment is an important assembly module for a digital drilling system, the division, design criteria and the principal design content of information module in the field equipment are discussed. By taking the component module of digital information for drilling pumps for example, the component module of digital information for the drilling pumps designed by using modular design method, open network in field equipment networks and field bus-bar have the characteristics of steady signal transfer, high reliability, strong ability for noise control and low cost for building field networks. Experiments indicate that the component module designed with the scheme is adaptable and reliable.更多还原
