Abstract: A maintenance support system includes a wearable device that provides an on-site maintenance worker with maintenance instruction information; a plurality of maintenance support terminals installed in a plurality of regions having time differences; and a maintenance management server connected to the wearable device and the maintenance support terminals. The maintenance management server includes a representative selection unit that selects a maintenance support terminal on the basis of representative level information, the standard work hours being fixed for each of the plurality of regions; and a translation unit that translates audio information transmitted and received between the wearable device and the maintenance support terminal selected by the representative selection unit on a basis of a language set on the wearable device and a language set on the maintenance support terminal selected by the representative selection unit.

Abstract: A disclosed communication device performs bidirectional serial communication by using a clock line and a data line. The communication device includes a starting condition detecting unit configured to detect a communication starting condition based on levels of the clock line and the data line and generate, in response to detecting the communication starting condition, a wake up signal for waking up another circuit in the communication device from a standby status; a clock sending/receiving unit connected to the clock line and configured to send/receive a clock signal; and an output control unit configured to fix the clock line at a predetermined level by using the clock sending/receiving unit so as to suspend the bidirectional serial communication after the wake up signal is received from the starting condition detecting unit and until a standby status cancel instruction indicating that the other circuit has woken up from the standby status is received from the other circuit.
