High-speed Signal Acquisition Based On FPGA

With the soaring development of science and technology,the demand of real-time monitoring of temperature and voltage in the field of national defense,astronomy,industry,and agriculture is increasing.Traditional system of acquisition of temperature is designed with SCM or DSP,and most functions of it are implemented with the help of software.Because it is time consuming when the software is operating,the speed of acquisition of the system is decreased.What5 more,the traditional system fails to control of logic of circuit well.However.FPGA is equipped with the property of parallel processing,high-speed acquisition,therefore the system based on FPGA is able to complement high-speed acquisition.The whole system is formed by five parts.The first part is the introduction of this paper,including the background of research of this paper,current state home and abroad,and the main content of this paper.In the second part,circuit of each module was designed.The third one is the controlling of each module of the whole system designed,and the module of smart sensor,displaying of data,data buffering and data transferring were designed.The forth part was designed to monitor the current temperature,and the PC interface is based on the platform of virtual instrument.The theory of the part of high-speed acquisition of temperature was given,and the three submodules were designed and tested.The module involved in controlling of voltage was designed and tested.And the working principle of FIFO in FPGA,the method of modeling of FIFO,and the thought of designing was introduced in this paper.What's more,the procedure of configuration of Bluetooth was detailed,and the wireless communication based on Bluetooth communication protocols was designed,simulated,and tested.Finally after the hardware was tested,the PC terminal,on the one hand,was designed to combine with the hardware part based on FPGA to test reliability of the whole system,on the other hand,it can store the data acquired which can be analyzed later on.This system use EP2C8Q208C8N to establish the platform of part of hardware and combine smart sensor with FPGA,instead of the thought of using traditional sensor with external circuit.Meanwhile the inner resource was used to configure FIFO as the memorizer of this system and wireless communication was established based on Bluetooth.This thought of design reduces the complexity of designing of system.While the PC interface was established with platform of Labview,which makes it more convenient for people to monitor this acquisition system.the system was tested for many times and the data acquired was analyzed with the reference of standard one,which proved that this system designed can be applied in the occasion when the real-time and wireless monitoring is required while the precision of data is defined in 0.5 ?...
