[Abstract]:The digital interphone monitor is used to monitor the analog interphone and the digital interphone, record the signalling, data service and voice service of the monitored system, and have perfect function of monitoring data presentation and management. The spectrum and protocol processing software of digital interphone monitor realizes spectrum processing, protocol data decoding and speech data decoding. Therefore, spectrum and protocol processing software is an important part of digital interphone monitor. In this paper, the development of various wireless communication system monitors at home and abroad is first summarized. Based on the analysis of the structure of the digital interphone monitor, The frame structure of digital interphone spectrum and protocol processing software (DMR / Digital Mobile Radio) and the main PDUs are described in detail, and then, according to the key techniques of digital interphone spectrum processing and DMR data decoding, The processing flow of the interrupt module of the spectrum and protocol processing software, the processing flow of the control information receiving module, the processing flow of the decoding and the protocol data processing module are designed. The processing flow of spectrum data processing module and the processing flow of data sending module. Secondly, in the TMS320C6748 DSP platform based on embedded SYS/BIOS operating system, using C language, the interrupt module of spectrum and protocol processing software is developed. The control information receiving module, the decoding and protocol processing module, the spectrum data processing module and the data sending module are used to realize the fixed frequency scanning. Panoramic spectrum scanning DMR speech data processing, FM speech data processing and DMR protocol information processing. Finally, according to the principle of black box testing, The spectrum data processing module and the decoding and protocol processing module of the spectrum and protocol processing software of the digital interphone monitor are tested. The test results show that the spectrum and the protocol processing software realize the fixed frequency scanning. Panoramic scanning DMR speech data processing FM speech data processing and DMR protocol information processing can meet the needs of users.
