The application of serial digital output thermometers TMP03/04 in temperature protection of thyristor power modules is introduced. And it focuses on two types of interface circuit and program design method between MSP430 MCU and TMP03/04.
The necessity of designing the virtual oscilloscope in the industrial computer system of the direct current shield is described. Its function requirement,interface design by VB and program design method are introduced.
Based on expert system theory and objective facing program design method, fault data base of numerical control machine was established according to fault diagnosing characteristics of numerical control machine by applying internet and database technologies to the studies, in order to realize offline fault diagnosis and to solve the problems quickly.
The properties of the TMS320VC5402,a DSP chip,and the ADS1251,a 24-bit A/D converter,were simply introduced in this paper. A data acquisition and processing system of sea gravimeter was developed using the ADS1251 and TMS320VC5402.The program design method of data acquisition and processing used in DSP,and the method of realizing serial communication between PC and DSP are presented.
Based on an example, this article briefly introduces multithread program design method using SQLJ of Oracle 8i,it mainly discusses the usage, creation of connection context and execution context and relationship between them.
We consider the operation, the logical structure, and the implementation features of MUL'TIPROTSESSIST/SM, the software support system of the multilevel structured program design method for mini- and microcomputers.
A system of algorithmic algebras is proposed, adapting the structured program design method to this particular class of control systems.
The object of this contribution is to take a practical program, which plots the three-dimension view for a plane distribution of the convected heat-exchange coefficient, as an example to provide a program design method using IBM-PC personal computer, a commonly used computer in this country at present, to plot a space curved surface. The first part of this article introduces the method of plotting space curved surface in Cartesian coordinate system. The second part is for polar coordinate system.
This article introduces the program design method on gearing design and checking computations of external toothing involute cylindrical gear under unstable varying stress and suggests main calculating formulars and imple diagram. The examples htsve been sucessfully calculated with the y pe Apple-I microcomputer.
