Abstract: An electric motor control device includes an electronic control unit configured to perform switching control of a switching element of an inverter in PWM control mode when a modulation degree is less than a first predetermined value, perform switching control of the switching element in square wave control mode when the modulation degree is greater than or equal to a second predetermined value, and perform switching control of the switching element in intermediate control mode when the modulation degree is greater than or equal to the first predetermined value and less than the second predetermined value. The intermediate control mode uses a switching pattern in which, in a pulse pattern in the square wave control mode, a slit or a short pulse having the same width as the slit is formed according to whether a pulse is present at the time when a phase current crosses zero.

Abstract: To prevent a delay in detection of a fault and the like and to cut down a load on a management side while making transmission of data appropriate in consideration of importance and properties of each type of the data in a case in which a large amount of data is transmitted from management target apparatuses. Items with high priority are processed first, and items with a low priority are allowed to be thinned out in accordance with priority and a weight that a management system 10 defines for each data item, thereby reducing a load. The thinning out is performed by limiting the number of data items to be processed once in accordance with a load level. Data acquisition intervals and priority for each item are dynamically changed by reflecting the importance of the data of each item and a change thereof. Trends of data and the like distributed using telemetry are observed and are fed back to load control through control using an AI or a rule base.

Abstract: A transmission system formed by connecting sites through an optical fiber stores at least unique information of the transmission functional devices for each site, connection information, and information of wavelength resources that can be accommodated in the optical fiber in a facility DB as DB information D2. When the number of wavelengths of order information for requesting the number of wavelengths required for transmission of optical signals between sites is larger than the number of wavelengths that can be accommodated in the optical fiber of the DB information D2, the number of wavelengths for each of the transmission functional devices required for enabling the number of wavelengths of the order information D1 to be accommodated in the optical fiber is designed using the design unit. Designed numbers of wavelengths are configured in the corresponding transmission functional devices using the configuration unit.
