A New Automatic Control Device for Rodent Suspension in Low/Microgravity Simulation
During the establishment process of simulating the partial load-bearing model of rodents in low gravity environment,there is often insufficient accuracy of the measurement results due to the in-terference of human factors.To solve this problem,a rodent suspension automatic control device in simulating low/micro gravity environment was designed.Firstly,the SBT440 pressure sensor module was used to realize the automatic measurement of rodent pressure value.Then,the stepping device based on STM32 microcontroller was used to realize the automatic adjustment of rodent suspension height.Moreover,the software control program of STM32 microcontroller was written in JAVA lan-guage,and the integrated debugging of software and hardware was carried out to realize the simula-tion of low/microgravity environment.Thus the establishment of rodent partial load-bearing model was achieved.The experimental results showed that the measurement error of 1/6 low gravity for ro-dents was 0.8%,which preliminarily verified the feasibility of the suspension device.
