Patent ID: 11962959

Abstract:
Equipment in a production facility is managed with use of information from the equipment and information from a sensor for measurement of a state of the equipment, while achieving a high degree of freedom in increasing and decreasing the number of such sensors.The present invention is provided with a gateway (10) and a server (20). The gateway is connected to a controller included in each piece of equipment and connected, without being intermediated by the controller, to an externally attached sensor accompanying the each piece of equipment. The server is connected to the gateway. The gateway carries out the processes of: receiving, from each controller, information indicative of an internal state of the piece of equipment; receiving, from each sensor, information indicative of an external state of the piece of equipment; and transmitting these pieces of information to the server. The server carries out a process of combining and outputting the information indicative of the internal state and the information indicative of the external state received from the gateway.
