PURPOSE:To obtain the remote monitoring device of a refrigerated container, which is simple, and also, safe, and moreover, exact and having a sense of reliance. CONSTITUTION:A temperature sensor 2 is installed in a temperature detection hole 3 of a refrigerated container 1, and also, a signal plug 4 is inserted into a receptacle 5, an internal temperature of the refrigerated container 1 and a state are detected, and transmitted to a remote monitoring device 9 through a radio transmitter/receiver 8 from a data converter 7 in a container monitoring device 6. A radio transmitter/receiver 12 receives a signal of its temperature, etc., and displays it on a display monitoring device 11. In the case temperature abnormality is generated or predicted, a signal for operating a defroster is generated from an input device 10, outputted to the data converter 7 through the radio transmitter/receiver 8 from the radio transmitter/receiver 12, and its control signal is transmitted to the refrigerated container 1 through the receptacle 5 from the signal plug. |
