CONCENTRATED MONITORING DEVICE OF FREEZING AND COOLING SYSTEM

摘要

PROBLEM TO BE SOLVED: To attain a concentrated monitoring device of a freezing and cooling system in which an erroneous inputting of a device identification code for the freezing and cooling device can be prevented and each of the freezing and cooling devices can be monitored properly. SOLUTION: There are provided one major monitoring device 2 and a plurality of terminal monitoring devices 5 each of which is installed at each of a plurality of terminal monitoring devices 5. The major monitoring device 2 and the terminal monitoring devices 5 perform communication to each other, thereby a plurality of freezing and cooling devices 6 are totally monitored. Then, each of the terminal monitoring devices 5 stores a device identification code pre-set for every device type of the freezing and cooling devices 6, and transmits the device identification code to the major monitoring device 2 when it is newly connected to the major monitoring device 2. The major monitoring device 2 discriminates automatically the device type of the freezing and cooling device 6 for the terminal monitoring device 5 in reference to the device identification code attained from the terminal monitoring device 5 to store the device type of the freezing and cooling device 6 so as to perform the monitoring in correspondence with the device type of the freezing and cooling device 6.
