The Establishment Of Computer-aided System Of Safety Psychology Experiment

Based on psychology and safety science, safety psychology synthesizing several relevant subjects becomes an independent displine, and is the application of psychology on safety domain. The safety psychological experiment is an important method of psychology research and development, and the researchers can test people's psychological and physical changes with various psychological experiment instruments, which are important tools of the research on safety psychology. At present, the instruments used in psychology are mainly the traditional entire hardware facility or the computer-assisted experiment systems, and they are mainly appied in the psychology teaching and the laboratories because of the restrictings of hardware, quality, price, and so on. It is very difficult to widely extend and apply them in enterprises. But in this paper, the psychological experiment computer-assisted system based on traditional instruments is a set of pure software system, and specially applies to safety psychology research.First of all, this paper introduces the evolution of psychological experiment instruments and the development and application of psychological experiment systems, explains their features with examples. Then, based on their features, it makes a kind of pure software plan of psychological experiment computer-assisted system based on the computer operating system. Secondly, in terms of psychology, this paper analyzes the people's unsafe acts and the factors causing the unsafe acts, then tests the safety property of people's acts in the way of psychological experiments. Immediately, based on the method and the index hypothesis of safety psychological experiments, in terms of computer program design, the paper introduces the general structure of the computer-assisted system of safety psychological experiments, and the function module design, development and realization process of each function testing system. Finally, summarizes the features of this system compared with today's psychological experiment instrument system, and the problems which need be resolved and promoted in future.This paper takes the visible programming ability of VB language and the data management function of the system as a platform, establishes convenient contact surfaces for experiment operations, realizes the functions that there is no paper in the processes of inputting the experiment parameters, control ing the experimental movements and demonstrating the results, and several sets of management functions of storing datum. The paper also establishes a set of computer-assisted software system of safety psychological experiments which realizes the functions only through the hardware and software of the computer itself. This system has these advantages :simple operation, good compatibility and extension, taking comforetably, so this system can displace the traditional psychological experiment instruments and can widely apply to occupational safety psychology tests of staff in various enterprises, such as electrical industry, construction industry and transportation.
