CURRENT COMMUNICATION DEVICE

摘要

A current communication device for automatically controlling a high speed railroad is provided to perform current communication in response to adjustment of communication speed at an MPU(Main Processing Unit) by being converted into the current communication through a current data conversion unit. A current communication device for automatically controlling a high speed railroad includes a current data conversion unit(3), and a serial communication unit(4). The current data conversion unit(3) receives current data from a high speed railroad device, and converts the received current data into voltage data. The current data conversion unit(3) provides the converted current data to an MPU. The current data conversion unit(3) converts the voltage data of the MPU into the current data and provides the converted data to the high speed railroad device. The serial communication unit(4) performs serial communication between the current data conversion unit(3) and the MPU.
