Based on the analysis of a typical elevator for car hydraulic system, a general modular simulation model is established. Through the case study of initial cavity volume and load change different effects on the dynamic performance of hydraulic system, the conclusion is found that the increase in initial cavity volume and load are conducive to reducing the hydraulic impact at the starting moment, but have an adverse effect on the dynamic performance at the stopping moment, and that the time to reach the steady state increases.

In recent years, the secret place’s frequency occurrence of leaks has brought huge economic losses on the national security、 social stability and economic life, which not only seriously harmed the national interest, but also raised a range of negative social impacts. Therefore, implementing effective monitoring strategies to protect the secret place is of great significance. In the paper, the wireless short-range communication technology ZigBee was adapted to design a wireless monitoring system, the short-range communication technology ZigBee can network quickly and has many monitoring terminals, so it can monitor the equipments and materials, persons and the environment in the building and protect the security of buildings from the source.

Mechanical parking system has been widely used，but there is no systematic inspection for the program logic of the control system software and the reliability of the hardware. To solve the problem, a real-time simulation system, based on dSPACE has been established, as well as modular simulation models. Through the test, it is proved that the simulation system can provide a near-real software and hardware test environment for the controllers of various types of mechanical parking system for the logic verification of the control system program and the reliability test of the hardware.
