基于蓝牙芯片的无线通信模块设计与开发

The Design and Development of Wireless Communication Module Based on Bluetooth Chip

本文综合运用BlueCore2-External蓝牙芯片、FB2520带通滤波器和平衡不平衡变换器、LTCC陶瓷天线等设计了一款蓝牙无线通信模块。该通信模块能够代替电缆,有效地应用于环境复杂多变的工业现场,实现现场设备、接入点、手操器等设备的无线通信。实际测试结果表明本文介绍的无线通信模块运行稳定,工作可靠。

By a comprehensive application of BlueCore2-External Bluetooth chip, FB2520 band-pass filter and balanced imbalance converters, LTCC ceramic antenna and so on, an industrial-grade Bluetooth wireless communication module is designed. The communications module can be used to instead of cable, effectively applied to complex and variable industrial field, realize wireless communication among field device, access point and Transcription Machine. The result of tests indicated the wireless communication module has been running steadily and working reliability.
