Device and method for controlling fault tolerance by standby double onboard equipment of train in RCBTC system

摘要

The present invention is to control the train through the data communication with the ground equipment on the train control system using a wireless daegiyi daegiyi of radio train control system on-board device that enables to establish a phase control and the phase control system of the high availability that can allow a defect occurs even if the fault has occurred in the design of wireless radio redundant structure of the relay structure relaying method relates to a device and method for fault tolerance. ; This is for realizing the present invention, made of the same structure of the first and second phase control device for detecting a malfunction of its own self-test on each circuit In addition, the first and second phase control device has a built-in soon as the normal operation signal to the other device or by sending a failure detection signal based operating a single phase control device, the other one of the phase control depending on whether the fault detection device in each made of a relay for operating a device in daegiyi standby system, the first and second phase control device connected to the communication line to the wireless transmission and reception device for a single phase structure of the interface, even if a fault occurs in one phase of the phase control device controls the entire off season by doing body to defect to the device rather than only being blocked invention made to allow the defect.
