With the explosive development of computer software technology and microelectronics, the intelligence instrument software is asked to be intelligent, networked and integrated by the complicated industrial automation system so that software development becomes the busiest part on the process of intelligence instrument development. To lessen the workload, the research on the automation technology of intelligence instrument software development becomes the focus. Some mature software development automation tools have been invented, developing exclusive theory and system structure. Through the study on the development process of intelligence instrument, especially on the software development, this paper introduces not only the basic information and development of intelligence instrument but also all parts on the automation process of intelligence instrument software development. It also builds the automation model of intelligence instrument development and provides a practical advice to reduce the workload during the software development.
