The embodiment of the invention provides a motor train unit air conditioner display setter. The motor train unit air conditioner display setter comprises an FPGA chip, a power supply circuit, a firstcurrent loop communication circuit, a nixie tube control circuit, a key control circuit and a second current loop communication circuit, wherein the power supply circuit, the first current loop communication circuit, the nixie tube control circuit, the key control circuit and the second current loop communication circuit are respectively connected with the FPGA chip; the first current loop communication circuit is used for being connected with an air conditioning unit, and the second current loop communication circuit is used for being connected with a monitoring device. According to the motortrain unit air conditioner display setter, the FPGA chip is adopted as a main control chip, so the problems that an originally imported motor train unit air conditioner display setter, a chip framework and a compiling environment of the chip framework are special, a chip supply channel is limited, and universality is poor are solved.
本发明实施例提供一种动车组空调显示设定器,该动车组空调显示设定器包括:FPGA芯片、电源电路、第一电流环通讯电路、数码管控制电路、按键控制电路以及第二电流环通讯电路其中,电源电路、第一电流环通讯电路、数码管控制电路、按键控制电路以及第二电流环通讯电路分别与FPGA芯片连接;第一电流环通讯电路用于与空调机组连接;第二电流环通讯电路用于与监视装置连接。本实施例提供的动车组空调显示设定器采用FPGA芯片作为主控芯片,解决了原装进口的动车组空调显示设定器,芯片架构及其编译环境较为特殊,芯片供货渠道受限,通用性差的问题。
