Abstract: The moving body receives data from a remote monitoring apparatus and transmits data to the remote monitoring apparatus, via the wireless communication network. A candidate route acquisition unit acquires a candidate route of the moving body to a destination. A communication quality evaluation unit evaluates communication quality of the wireless communication network at each location included in the candidate route for each direction of communication by using communication quality information for each direction of communication. A candidate route evaluation unit evaluates communication stability of the candidate route by using communication quality evaluated for each direction of communication. A route determination unit determines a movement route of the moving body among the candidate routes by using an evaluation result of the communication stability.

Abstract: This invention solves the problem that, if a loss of signal or other anomaly occurs on a line side, intermittent problems occur in a signal outputted to a client side, resulting in trouble with subsequent signal processing. This optical-transceiver control circuit comprises a signal-generating means for generating a dummy signal that has approximately the same characteristics as an electrical signal generated from an optical signal inputted to an optical transceiver, a switching means for receiving an electrical signal and selecting and outputting either the received electrical signal or the generated dummy signal, and a controlling means for changing the signal selected by the switching means from the electrical signal to the dummy signal if a notification indicating an anomaly in the optical signal is inputted.
