Abstract: Through the simple introduction of a sound measuring temperature system, the basic structure of the system composition can be gotten. Then the design of the software is particularly introduced. This paper mainly describes the Site Control Part and Monitoring Center Part of the operation monitoring through the simulation of a set of experimental devices. It describes all the functions of the two parts. What’s more, the software communication protocol, fault analysis and software operational testing program are also briefly introduced in this paper

Abstract: Being aim at designing a system controller used in the Noninvasive Bidirectional Positive Airway Pressure Ventilation (N-Bi-PAPV) and advancing this medical device to serve the respiratory patients who suffer from the OSAHS, COPD and etc, by using an embed ARM Microcomputer LM3S9B92, the system controller including its circuit diagram and embed software was designed in accordance with the request of Bi-PAP medical ventilator. And the ventilators critical parameters were clearly defined and ranged for this system. After testing in a spontaneously breathing simulator, this system controller may be used to control the ventilator performing function well.

Abstract: Airborne panel series circuit modules are used to process and transform the information between the aircraft cockpit control panels and the avionics system. A kind of test system software design for the airborne panel series circuit modules using the PXI host system as the testing platform is introduced in this paper. The test system architecture, software design idea and realization method are also discussed. In order to test the airborne panel series circuit modules, whose all kinds of interface signals are needed to provide according to the circuit modules’ test requirements. The most important function of test system is to provide excitation signals to the tested object, while the response signals of the tested object is collected, so the test results can be formed by the test criterion. In the software design, the different test processes are used for the different test objects. The test work can be completed according to the test process, the test data and test results formed in the test can be saved to the database. In the test process, the connection between the test program and database is established. All test data and results are managed by the private database management system. The entire test system uses the top-down design methodology, and host computer adopts PXI system to control the tested modules. The test system has been well applied in project, and its stability and excellent performance have been proved in experimental work.

Abstract: The research of software design, based on the supervisory control theory, is an important content in software cybernetics. The existing software model used in the software design with the supervisory control theory is Polynomial Dynamic System (PDS), which is transformed from SIGNAL files. This obstructs its widespread application. Extended Finite State Machine (EFSM) model is widely applied in software engineering field and it may alleviate the state explosion problem of Finite State Machine (FSM) to some extent. In this paper, the EFSM model is suggested to study software design problem. This paper proposed two kinds of software design problems based on EFSM model. For the first problem, a necessary and sufficient condition for software existence is obtained. For the second problem, a necessary and sufficient condition for software existence and an optimal algorithm to such software design are presented.

Abstract: The optimal design for computer control software is studied. Since computer control software is susceptible to interference during the control process, a computer control software design model based on improved PID algorithm is proposed. The PID algorithm is combined with particle swarm algorithm to calculate PID control parameters, which is viewed as evolutionary particles of the particle population, and given a certain flight speed in the search space, the speed of the particles will be adjusted iteratively and dynamically in accordance with the experience of population’s evolution calculation, in order to achieve computer control software design. The simulation results show that the proposed algorithm applied for computer control software design, can improve the control precision and meet the actual needs of computer control.

Abstract: In order to solve the problem of inconvenience for integration and operation complexity, the micro-flow fluid supply system based on STC12 series MCU is presented and implemented. STC12 has many advantages such as ultra-low power consumption, rich chip designs, high performance cost ratio, high speed, etc. The feeding system mainly consists of mechanical parts, a miniature stepper motor, a micro-stepping driver, MCU and its control circuit. The software program is written by PC to manage the feeding process of the start-stop, rotation direction, acceleration and deceleration of the motor. Both the flow rate and the flow flux can be controlled precisely and flexibly, so as to ensure that the test liquid is slowly delivered under quasi-equilibrium condition to shape into a satiated and uniform drop.
