Patent ID: 8081574

Claim:
A monitor device provided to a broadcast radio wave retransmission system that comprises a receiving device and a transmitting device, the receiving device receiving broadcast radio waves transmitted from a broadcast station, and processing received signals so as to output the received signals as broadcast signals for retransmission, the transmitting device being disposed in an area where the broadcast radio waves do not reach, amplifying the broadcast signals to a predetermined transmission level, and outputting the broadcast signals to a transmitting antenna so that broadcast radio waves corresponding to the broadcast signals are retransmitted from the transmitting antenna, the monitor device monitoring an operational status of the system and, when an error occurs, reporting the error to an external monitoring center, the monitor device comprising: a packet communication device performing wireless data communication with an external device through a public packet communication network for mobile devices; a report data transmitting device that transmits report data, when an error occurs in the system, so as to report the error to the monitoring center through the packet communication device; a communication status determination device that determines whether or not transmission of report data is successfully performed by the report data transmitting device; a transmission error history storage device that stores an error, when the communication status determination device determines that an error occurs in transmission of the report data, as a transmission error history in a storage device; and a retransmission instruction device that makes the report data transmitting device retransmit the report data, when the communication status determination device determines that an error occurs in transmission of the report data; wherein the retransmission instruction device is configured to: count a number of times the report data is transmitted; determine whether or not the number of times the report data is transmitted has reached a predetermined upper limit value (M); and retransmit the report data to the monitoring center when the number of times of the transmission has not reached the upper limit value (M), and set the number of times of the transmission to an initial value (“O”) when the number of times of the transmission has reached the upper limit value (M) so that the process proceeds to transmission of report data to be subsequently transmitted.
