Abstract: A remote management system wherein a central control apparatus is connected with machines installed in a shop by communication means, so that set values of the operating conditions of each machine set in a microcomputer within the machine can be changed from the central control apparatus and, resetting of the microcomputer and restarting of the machine can be directed from the central control apparatus, thereby eliminating the need for dispatching personnel to the shop and reducing the management cost, while in case of a trouble in the machine, information indicating the occurrence of the trouble and information specifying the location of the trouble are transmitted to the central control apparatus thereby to shorten the time required for restarting the machine by the personnel and improve the management efficiency, and further featuring a controller which periodically collects information related to the operation of the machine from the microcomputer and stores the information in a memory thereof while erasi

Abstract: A remote management system where a central control apparatus for controlling machines installed in plural stores from remote on receiving data of working conditions of the machines, which is transmitted from terminals of the stores, for displaying a layout of the machines in each store, a machine kind, a layout of the store such as a wall, an entrance and a window on blocks, for example, by a coloring, a hatching of the block, on and off of the display of the block and the like.

Abstract: A remote management system where data detected by a sensor for detecting a condition of a machine is input from an input port of an interface unit of a control unit such as a microcomputer, and the interface unit is connected via a data transmission controller over a communication line with a central control apparatus which manages a machine like a washing machine from remote, and further the detected data is transmitted from the interface unit to the central control apparatus though the control unit is inapplicable to communication, while the interface unit passes the detected data of the sensor without processing and outputs the detected data to the control unit by means of setting the state of an output port thereof same as that of the input port.
