Abstract: A device to control the amount of seeding is designed, which replaces the people in the entire reseeding process of double digging, planting, covering soil. So the work efficiency is improved. According to the design requirements of the seeding device, Solid Edge V18 software is used to build 3D model. On the software platform, the parts are designed and assembled. The correctness of the design scheme and feasibility is confirmed. Linkage has two functions such as blocking soil and protecting the seed. Using the software for 3D modeling greatly shortens the design cycle, improves design efficiency and design quality, and reduces the cost.

Abstract: This PID temperature measurement and control experiment platform is composed of LabVIEW software, PCI-6024E data acquisition card and SC-2075 breadboard. Its hardware uses thermocouple to measure temperature and controllable silicon to control the current of the electric heater, thus to control temperature; and its software uses LabVIEW to design the front panel and block program of the control system. After the hardware experiment platform is built and connected with the program, it could realize PID temperature control and high or low temperature alarm at the same time. The system is proved to have practical value and application significance.

Abstract: Based on the mathematical model of the step motor, a new method for modeling and simulation of step motor based on LabVIEW is proposed. The reasonability and validity are testified by the coincidence of the simulation and experimentation results and theory analysis. This method offers a new thinking for designing and debugging actual motors.
