Abstract

Communication system according to this invention Provided in electrical equipment such as Refrigerator that contains Bulk transmission units such as electric fans, dampers And data receiving units, detectors, thermistors, and other such communication systems are located in close proximity to the receiving and transmitting units. Such communication system consists of Multiple sub-controls to control the operation of multiple transmission units The main control for controlling electrical equipment by controlling the operation of each sub-control. Single communication cable to connect the main and sub-controls. To allow communication between each other, two-way communication between the main and individual sub-controls. It is done through a single communication cable for connecting the main and sub-controls. To allow communication between each other Two-way communication between main controls And individual sub-controls It is done through the communication cable. The above communication systems allow for a reduction in the number of cables used for connecting the main control to multiple receiving and transmitting units and establishing a method for routing the cables. One of the consequences is Makes electrical devices compact and reduces manufacturing costs.
