Simulation Platform of Monitoring and Tracking Micro System for Dangerous Chemicals Transportation

Abstract

Real test method of monitoring and tracking micro system for dangerous chemicals transportation has many disadvantages: long test cycle, high test cost, high test risk and bad reproducibility. Aimed at these disadvantages, a simulation platform which can be used for the simulation test of monitoring and tracking micro system is developed. This simulation platform is composed of motion simulator and simulation environment. The motion simulator is a kind of parallel robot with Hexaglide structure and has a total of 8 degrees of freedom(DOF). This parallel simulator can not only realize the motion simulation of yaw, pitch and roll, but also provide pure linear motion in the Y direction, which is significant for the acceleration or deceleration simulation. The simulation environment is developed with a sealed cavity, in which a steel tank is used to simulate the tanker for dangerous chemicals transportation. The environment parameters such as temperature, humidity, concentration of combustible gas, the pressure and liquid level in tank can be measured and changed. Based on the motion simulator and the simulation environment, motion parameters such as position, attitude, angular rate, velocity and acceleration and the environment parameters can be measured simultaneously by micro system and standard sensors. With the comparison of these measured data, the micro system can be validated. This simulation platform provides a good test method for the monitoring and tracking micro system and has important significance for dangerous chemicals transportation.
