Hardware Structure

According to the practical requirements of filling refrigerants of refrigeration maintenance industries, an high-precision measuring and control system for refrigerant with MSP430 is designed in this paper. High-precision weighing sensor and high-performance amplifier are adopted in the hardware structure, and an improved amplitude-limiting and shake-disappearing filtering algorithm is used in the software data processing. The design is capable of not only achieving the purification and recycling of refrigerant effluent, but also conducting the functions of pressing, vacuumizing and leaking hunting of both high and low pressure. The actual results in the practical refrigeration maintenance industry show that this measuring and control system precision can reach0.5, which is reliable in operation, good in stability and capable of solving the problem that the discharge of waste refrigerant may pollute the environment.

Purpose This paper aims to propose a spreadsheet method for modeling and simulation of a retraction system mechanism for the retractable self-launching system for a high-performance glider. Design/methodology/approach More precisely, the method is based on parametric link design using Excel spreadsheets. Findings This method can be used for kinematic and dynamic analysis, graphical plotting and allows simulation of control kinematics with the ability to make quick and easy parametric changes to a design. It also has the ability to calculate the loads imposed on each component in the control system as a function of input loads and position. Practical implications This paper shows that it is possible to model complex control systems quickly and easily using spreadsheet programs already owned by most small companies. The spreadsheet model is a parametric model, and it gives a simple visual presentation of the control system with interactive movement and control by the user. Originality/value This spreadsheet model in conjunction with a simple CAD program enables the rapid and cost-effective development of control system components.

Measurement And Control

This paper presents the composition and working principle of the hardware and software of the measurement and control system based on VeriStand and Simulink for a tracked model vehicle. The hardware of the system is composed of a CompactRIO controller and acquisition cards, torque/speed sensors and a gyroscope. The vehicle control logic model and data processing model are built in Matlab/Simulink. VeriStand is adopted to manage models and interact with people. The system can control motor speed on both sides of the vehicle and collect data such as sprocket torque and speed, vehicle attitude on real-time. At last, we test and verify the system can work successfully.

An accurate and automatic weighting method was used to satisfy the command. The system consisted a hopper, a vibration propellant delivering equipment, a particle separation equipment and control system. The main controller and the programmed logic controller were used to control the system to make sure the high precision of particles weighting as host computer and slave computer respectively. The result shows that the method can solve the key technology of the automatic weighting of the small-bore experimental cartridge and offers significance for the automatic weighting of standard particles.

This passage mainly introduces about the design of liquid level and boundary measuring control at sewage re-flooding craft in small split oil field. In order to achieve automatically cutting flooding and re-flooding in the procedure in small split oil-field, the scheme is to test liquid level and boundary by using high performance to price ratio new double level gauge, to utilize electric valve instead of mechanical valve and to choose PLC to control system logic. Eventually, it will reduce the labor intensity.
