| 摘 要： | 介绍以DSP为核心的SINS／GPS,分布式控制组合导航计算机的设计方法。选用TI公司的DSP作为导航算法处理机，采用TL16C752B、MAX3232、MAX3362设计RS-232／485／422异步串口，另一片DSP控制GPS-OEM板串口输出的报文，采用CPLD作为调度机实现M／MU六路数据采集，各处理器通过双端口RAM共享数据，实现了分布式控制。系统还采用GPS接收机输出的1PPS脉冲，结合CPLD产生的时序实现MIMU和GPS数据的同步采集。

| Abstract: | The design method of distributing control navigation computer for MIMU/GPS integrated system based on digital signal processor(DSP) have been introduced in this paper.DSP manufactured by Texas Instruments has been selected as navigation algorithm processor.The UART RS-232/485/422 has been designed based on TL16C752B and MAX3232/3362.The system use another DSP to receive the GPS OEM board's output message.Adopting complex programmable logic device(CPLD) to collect the 6 channels micro inertial measurement unit(MIMU) data.The processors share the data from dual-port static RAM and system realizes distributing control.Using the 1PPS signal from GPS receiver and combining the time sequence produced by CPLD,the system realizes synchronal data collection to MIMU and GPS. |
