这里介绍的广播电视事故记录仪,可把事故的各种信号记录下来,其中事故的日期和时间值是用语言合成的。这样,所有信息均为模拟量并用磁记录。由于模拟信号本身具有较大的冗余度,故记录的保存和检索方便、可靠。仪器采用单片微机和单片语言合成处理器。 The radio and television accident recorder described here records various signals of an accident, where the date and time of the accident are synthesized in words. In this way, all information is analog and recorded magnetically. As the analog signal itself has greater redundancy, so the record of the preservation and retrieval convenient and reliable. Instrument uses single-chip microcomputer and single-chip language synthesis processor.
