In order to reach the requirement of applying for the multi - objective and multi - parameter measuring , we adopt the distributing computer controlling system which the at89c52 single chip was used as core in the system , also the circuit of signal conditioning and data acquisition and processing are all integrated in the system . we use nixie tube to fullfill the displaying function and adopt high - capacity memory to record the data of production process 同时为适应工厂要求对多目标、多参数进行监测的要求，采用了分布式计算机控制系统，该系统以at89c52单片机为核心，内部集成了信号调理、数据采集与处理、显示等电路并扩展了大容量存储器以保存最近几次生产过程的检测数据，同时还采用了rs485网络总线技术可以方便的将数据传输给上位控制中心。

If the chip remains sending state , it will take the data spread spectrum and modu - late , then sent forth by ad9768 . the chip can be controlled throug h writing data in the interior 87 registers . secondly , this paper designed control system of twice civil air defense alarm system . because the scm " s port number was limited and port driving power is feebleness , this design realizes nixie tube ' s display drive with keyboard management chip max7219 and realizes true time display with ds1302 , which can economize scm i / o port and make circuit connection simplicity 通过对其内部87个寄存器写入数据可对其进行控制。其次，本文对二次人防警报系统控制系统进行设计，针对单片机端口数目有限、端口驱动能力较弱等问题，使用键盘管理芯片max7219实现数码管显示驱动，用ds1302实现真时钟显示，节省了单片机i / o口，电路连接简单。
