在战场探测目标应用中,被动声探测技术有其独特的优势,能够有效的弥补其他探测方式的不足。针对被动声探测系统依靠有线数据传输的灵活性低、复杂度高等问题,设计了基于ZigBee的被动声探测数据采集系统。利用CC2530作为无线传输模块芯片,并通过SPI与信号采集和处理芯片TMS320LF2407连接。在CC2530中使用了TI公司提供的SimpliciTI协议堆栈进行软件设计,将探测结果传回接收端连接的1602液晶显示。实测结果表明本系统能够稳定无误的传输目标探测信息并实时地传回接收端。

In the application of target detection, passive acoustic detection technology has its unique advantages, which can effectively compensate for the deficiency of other detection methods. In order to solve the problem of low flexibility, high complexity and other issues result from passive acoustic detection system that relies on the wired data transmission, the ZigBee-based passive acoustic detection data collection system was designed. As the main chip of the wireless transmission module, CC2530 was connected with the signal acquisition and processing chip TMS320LF2407 through the SPI. SimpliciTI protocol stack of TI was applied in the software development of CC2530 for transmitting the detection results back to the receiver and displays on the connected LCD 1602. The results of experiment indicate that the system can securely and correctly transmit the information of target and in real-time back to the receiver.
