The utility model discloses a remote input/output port data acquisition system based on an embedded platform. According to the utility model, analog quantity signals are locally acquired in a centralized mode, recorded in the remote input/output port data acquisition device based on the embedded platform, and converted into a digital signal by an A/D (analog-to-digital) conversion interface circuit and the digital signal enters a microprocessor; the microprocessor processes the signals and then outputs the processed signals, and real-time data is displayed through an LCD (liquid crystal display); the acquired data is remotely transmitted to an upper system through an RS485 interface circuit or Ethernet interface circuit; the power supply circuit specially provides power for the microprocessor so as to ensure the stable work of the microprocessor; a keyboard and a reset circuit are operated to input operation instructions into the microprocessor; and as the peripheral input circuits of the microprocessor, an J
