Data Acquisition And Wireless Communication System Design

According to the character of the shooting range test, the paper designs a remote controlled data acquisition system. The system is made up of 3 data acquisition branch parts and a control center. Branch parts play a role as data acquisition and saving. Control center far away communicates with and controls branch parts in use of wireless technology.Data acquisition branch parts use FPGA as control center, synchronously sample four-channel simulation signals and then store the data in the flash. There are two kinds of interface in each branch part. Serial ports with simple protocol are used to communicate with wireless communication part, and the protocol is implemented by FPGA. USB protocol is very complicated, but the data rate is very high, so it can be used to read the data in the flash. The protocol is realized by the special USB chip of inner MCU.Control center and the branch parts communicate with each other by means of wireless communication module. The critical part of wireless communication module is CC2430. And the Communication protocol is realized by the inner MCU.Write the driving program and applicable program to control the data acquisition system. The control program can manipulate wireless communication module in use of serial port in order to communicate with the branch parts and control the acquisition procession. After acquisition, the computer can read data in flash in use of USB port.
