The invention relates to a controllable code sending device for simulating track signals, which comprises a processor, an FSK (Frequency Shift Keying) signal generation module and a signal amplification circuit which are connected in sequence, and also comprises a power amplifier board, a recovery circuit and a comparison circuit, and the input end of the power amplifier board is connected to the output end of the FSK signal generation module; the output end is connected to the input end of the recovery circuit and the input end of the comparison circuit, the output end of the recovery circuit is connected to the processor, the output end of the comparison circuit is connected to the FSK signal generation module, and the processor is further connected to the upper computer; and the power amplifier board collects the FSK signal output by the FSK signal generation module and forwards the FSK signal to the recovery circuit and the comparison circuit. Compared with the prior art, the system has the advantages that the stoping circuit and the comparison circuit are added, and the signals generated by the FSK signal generation module can be stoped, compared and shaped, so that the accuracy and reliability of the generated FSK signals are improved.

    本发明涉及一种模拟轨道信号的可控发码装置,包括依次连接的处理器、FSK信号生成模块和信号放大电路,装置还包括功放板、回采电路和比较电路,功放板的输入端连接至FSK信号生成模块的输出端,输出端分别连接至回采电路和比较电路的输入端,回采电路的输出端连接至处理器,比较电路的输出端连接至FSK信号生成模块,处理器还连接至上位机;功放板采集FSK信号生成模块输出的FSK信号并转发至回采电路和比较电路。与现有技术相比,本发明增加了回采电路和比较电路,可以对FSK信号生成模块生成的信号进行回采和比较整形,从而提高生成的FSK信号的准确性和可靠性。
