In accordance with the aerial telemetry of the temperature measuring oflarge areas of oceans, a kind of interface with its own circuits and software for data aquisilion on MDR-Z80 computer has been developed by us. Since the interface fully uses 280-CTC chips, so the parameters for aquisition and delay arc much flexible, and the majority of the automatic aquisistation processing is realized by the hardware, thus it will take much less CPU lime.

In accordance with the aerial telemetry of the temperature measuring oflarge areas of oceans, a kind of interface with its own circuits and software for data aquisilion on MDR-Z80 computer has been developed by us. Since the interface fully uses 280-CTC chips, so the parameters for aquisition and delay arc much flexible, and the majority of the automatic aquisistation processing is realized by the hardware, thus it will take much less CPU lime. It is cxtrcmly useful for the multichannel aquisilion systems consisting of general chips, and the software developed by advanced language and assembly language facilitates the realization of aquisition and outpul.

针对海洋大面积测温航空遥测技术,研制了一块数据采集与MDR-Z80计算机的接口.其中设计了电原理图和相应的软件.该接口电路由于全采用Z80-CTC芯片,对采集时间、计算延时等参数极为灵活,大部份自动采集均靠硬件实现,因而使CPU占用时间极少,这对于一般的芯片组成多通道的采集极为有用.软件用高级语言和汇编语言结合编程,使采集与输出易于实现,同时也是一种实用的测试接口.

By use of one A/D converter to sample the multi-channel signals,it is not only that the speed is limited, but also that the noise produced by the channel transforming and the disturbing between channels is difficult to be overcomed.When the phase anlysis between different channels is required,the phase errors between sampling channels is also difficult to be overcomed.In this paper.to solve the above problems ,the multi-module interleaving data acquisition technique is introduced,the software and hardware implementing techniques for multi-channel sampling or for single channel super-high speed sampling by use of the interleaving technique are provided ,the error correcting methods for implementing interleaving technique and the fault-tolerant design of data acquisition system by using interleaving technique are discussed.

用一片A/D进行多通道数据采集不仅在速度上受到限制,而且难以克服通道间转换过程中引入的嗓声和道间串扰。在需要进行不同通道信号之间的相位分析时,各采样通过之间的相位误差也难以克服。介绍了多通道并行数据采集技术,给出了利用并行技术进行多通道采集以及利用并行技术进行单路信号超高速采集的软/硬件实现技术,讨论了实现并行数据采集的误差校正方法以及利用并行技术进行数据采集系统的容错设计。

In this paper,a new way for ultra wide band (UWB) signal A/D conversion and signal reconstruction using an array of lower speed A /D converters is introduced. Its basic idea is to decompose a signal into several continuous frequency bands ,so that a specific,subconverter can be assigned to each band signal,then make use of the theory of quadrature mirror filter to recon-struct the digital sequence corresponding to the input analog signal.Simulation results verifies the good performance of the way.

提出了一种超宽带(UWB)信号多通道采集及信号波形恢复方法。其基本思想是把UWB信号分成若干频带,对每个频带用低速A/D进行采集,然后用镜像滤波器恢复信号波形。仿真结果表明:这一方法可消除多通道采集系统中通道间耦合产生的失真,能很好地恢复信号波形。
