| PFC developed by our drive module test equipment are in the PFC in order to drive the process of module production and product testing in the detection of product quality testing equipment.PFC driver module is running at a variety of signals will be issued,and the test equipment is through the acquisition of these signals to digital-to-analog conversion,the signal analysis of the data,and then a product is found to the problem,pointing out that the crux of the problem and the solution to the problem.And a variety of signal data can be stored in a variety of storage devices,such as SD card,U disk,PC hard disk and so on in order to analyze data maintenance personnel.Saving human and material resources and time savings.The design of the test equipment be divided into two major parts:1.Hardware.2.Software.We divided hardware into two parts:1.Test equipment design of the modules,that is,to deal with a variety of signals,the hardware circuit.Including power supply units,voltage protection unit,current protection unit and the SD card storage,serial communications and so on.2.STM32 family of chips used to detect the purpose of its implementation. Put all the above-mentioned unit of the port-port-one correspondence with the single-chip,using the power of STM32 implementation tools to test the functionality of the unit.TI are STM32F103xx in the United States beginning in 2007 to market the ultra-low power microprocessor.STM32F103xx the main characteristics and mechanical properties have six points.ARM32 series STM32F103VB-bit single-chip using Cortex-M3 CPU.72MHz,90DMips.STM32F103VB series of single-chip memory from 32K bytes to 128K bytes flash program memory,6K bytes to 20K bytes SRAM. With flash memory,USB,CAN,7 timers,2 ADC,9个communication interface, a wealth of enhanced I/O ports and connected to two APB peripheral bus. Including two 12 was ADC,3 general-purpose 16-bit timers and a PWM timer, including standard and advanced communication interfaces:two 12C and SPI, 3个USART,a USB and a CAN.Low power consumption,the supply voltage of 2.0V to 3.6V,3 power-saving modes:sleep,shutdown and standby mode with automatic wake-up function.Nested interrupt controller,interrupt vector supercomputer deal with many,to 43 maskable interrupt channels,interrupt response is very short delay,only 6 CPU cycles,and with the tail of the link function.We divided software into three parts:1.To test the overall framework of design tools.Equipment used in this test are followed Rhapsody Unified Modeling Language UML model-driven software development platform,Rhapsody can maximize the system,hardware,software and test engineers to more flexible and coordinated manner to optimize the development and communication. Rhapsody not only to support the UML visual notation,the system completely model the structure of all levels,and also supports the adoption of simple form button,implementation and testing of these models.Rhapsody support the implementation of the three languages:C,C + + and Ada,in accordance with the design of the structure and customer behavior model,just above the button you can have a code in three languages.2.Testing equipment unit of the specific design.Rhapsody of the advantages of using the various software packages and hardware units are divided into packets,the hardware package for the control of hardware,software packages are system-wide implementation of the logic function.Package with the hardware through the hardware package to call the function of single-chip hardware implementation of control,and through the completion of message or event-driven communication between hardware and software.This separation of hardware and software design to update our Convenience Products,when the replacement of the hardware when the hardware can change the contents of packages can be,and package the entire system can not change the logic function,thus greatly reducing software development cycle.3.Designed PC program.PC connection to VC + +6.0 instrument for opening up the use of the NI's NI Measurement Studio.Measurement Studio for Visual Studio.NET and Visual Studio 6.0 environment provides an integrated package,including a variety of commonly used measurement and automation controls,tools and libraries.Measurement Studio for Visual C + + in the development of measurement and automation system design provides an interactive way. Because these tools have been integrated into the Visual C + + development environment,so you can use Microsoft tools such as call them directly.System R & D personnel are from the actual job,the functions of the system in the laboratory phase of systems development,in the control method on a new approach and ideas,in order to monitor R & D Product class had a meaningful pre-design work.To sum up,the whole system design is completed,provided for the R & D personnel has a lot of practical application examples of the value of the hardware and software design,testing and monitoring for a variety of technical upgrading of a good reference.Measurement at the test industry to flourish today,I hope to be able to test this thesis measures contribute to the development of technology. |
