DDX-CZ型铁路信号点灯单元采集装置总、分机全部采用智能型微型计算机控制，能够实时监测站内、区间信号机各灯位灯丝的工作状态。在主灯丝故障自动转换成副丝时，及时给出断丝故障信号机灯位名称的准确报警信息。灯丝报警信息在提供给电气集中控制台的同时，还可以通过CAN口与微机监测系统通讯，转发报警信息。

    The collection device of DDX-CZ railway signal lighting unit is controlled by intelligent microcomputer, enabling to monitor the real-time working status of lamp filament of annunciators in stations and sections. When the auxiliary filament works in the event of primary filament fails, the accurate alarm information of faulty annunciators will be given promptly. At the time when filament alarm information is provided to the electric centralized console, it is possible to communicate with monitoring system via CAN port to forward alarm information.
