数据解调器 meaning in Chinese

data demodulator

The catv charge and control system is mainly composed of the management software 、 the header data modulator and the terminal charge and control equipment . i am responsible for design catv charge and control equipment and test system . the header data modulator is used to encrypt the control single from computer and transmit it into the appointed frequency . the terminal charge and control equipment demodulate out the control single from data modulator and transmit it to the addressing control part , where the demodulated fsk single is received and well - handled by the cpu unit , decode the unauthorized signals and deliver it to the shut point , shut point make use of capability of wideband anf characteristic of shut , then the signal of illegal customer will be turn off and vice versa , the legal customer can receive the normal signal
前端数据调制器完成对计算机输出的控制信号加密处理,将指令码载送到一指定频率点。终端收费控制器解调出控制信号,送至单片机寻址控制部分。单片机寻址控制部分接收经fsk数据解调器送来的信号,送入cpu单元后,解出不授权信号,然后向关断部分送入信号,关断部分利用pin二极管的宽带工作能力以及关断特性,实现对非授权用户或者非法用户的信号关断,使之不能正常收视,缴费用户进行开通正常收视,达到控制用户通道的管理。
