PURPOSE:To obtain a communication control device of a refrigerator which enables execution of stable communication irrespective of a delay operation of a transmission-reception control signal caused by the delay characteristic of a noise intercepting part and the characteristics of a totalizing unit, in regard to the communication control device of the refrigerator which is provided between the totalizing unit and a terminal unit of the refrigerator and equipped with a converting part of a communication voltage between the totalizing unit and the terminal unit of the refrigerator, the noise intercepting part constructed of optical elements and a transmission-reception control part. CONSTITUTION:This device is constructed of a converting part 7 of a communication voltage between a totalizing unit 1 and a terminal unit 5 of a refrigerator, a noise intercepting part 8 and a transmission-reception control part 6b constructed basically of CPU 15, ROM 17 and a serial port 16. |
