The invention provides an underground parking garage AGV communication device. The underground parking garage AGV communication device comprises an antenna, an amplifier, an orthogonal modem, a local oscillator, a first frequency mixer, a first filter, a second frequency mixer and a second filter. The antenna, the amplifier and the quadrature modem are electrically connected in sequence; the antenna is a short-wave antenna; the output end of the quadrature modem is electrically connected with the first mixer and the second mixer. The output end of the local oscillator is electrically connected with the first mixer and the second mixer. The output end of the first mixer is connected with a first filter; the output end of the second mixer is connected with the second filter. The technical problem that communication with an automatic parking system may be interrupted due to the fact that WIFI signals of an AGV are weak when the AGV runs to a corner area of an underground parking lot in the prior art can be solved.

    本发明提供一种地下停车库AGV通信装置,包括:天线、放大器、正交调制解调器、本地振荡器、第一混频器、第一滤波器、第二混频器和第二滤波器;天线、放大器和正交调制解调器依顺次电连接;天线为短波天线;正交调制解调器的输出端分别与第一混频器、第二混频器电连接;本地振荡器的输出端分别与第一混频器、第二混频器电连接;第一混频器的输出端连接第一滤波器;第二混频器的输出端连接第二滤波器。本发明可以解决现有技术中存在的AGV小车行驶到地下停车场的角落区域时,其WIFI信号较弱,可能会造成与自动泊车系统的通信中断的技术问题。
