Publication number: 20230305043Abstract: An energy conservation assistance apparatus includes an event occurrence time extraction unit, a degree of change calculation unit, and a display control unit. The event occurrence time extraction unit refers to facility operation history information included in a reference period and a designated period to extract occurrence times at which a predetermined event has occurred in each of the reference period and the period of interest. The degree of change calculation unit calculates a degree of change in an operation pattern of a facility obtained from a distribution of the occurrence times at which the predetermined event has occurred in the period of interest, relative to an operation pattern of the facility obtained from a distribution of the occurrence times at which the predetermined event has occurred in the reference period. The display control unit presents information regarding a degree of change to a user.Type: ApplicationFiled: May 22, 2023Publication date: September 28, 2023Applicant: Mitsubishi Electric CorporationInventors: Toshihiro MEGA, Tomohiro NARUI, Shuichi MURAYAMA, Fuyuki SATO, Genta YOSHIMURA

Publication number: 20210116876Abstract: An apparatus control unit (54) executes baseline judgment control of canceling power consumption limitation for a management target apparatus (20) throughout a predetermined judgement period within a demand term. A demand control execution judgment unit (48) judges whether or not a value of a baseline BL, which is an estimated value based on an integrated value of power consumption per building in the judgment period, exceeds a demand control execution value P_Dmd by a demand-term end point. When it is judged that the value of the baseline BL exceeds the demand control execution value P_Dmd by the demand-term end point, the apparatus control unit (54) executes demand control of limiting power consumption of the management target apparatus (20), after the judgment period.Type: ApplicationFiled: December 29, 2020Publication date: April 22, 2021Applicant: Mitsubishi Electric CorporationInventors: Shinichiro OTANI, Fuyuki SATO, Yoshinori NAKAJIMA, Hiroki KAWANO, Toshihiro MEGA

Patent number: 10891332Abstract: A control method analysis unit acquires a correspondence relation between signs and model numbers from an apparatus table of an instrumentation diagram, and acquires signs and apparatus symbols, and connection relation among apparatuses, from a drawing of the instrumentation diagram. Subsequently, the control method analysis unit acquires an apparatus classification drawn on the diagram by searching an instrumentation apparatus classification database based on the model numbers, and decides a temperature control method employed by an instrumentation indicated in the instrumentation diagram, from the apparatus classification and the connection relation. The control method analysis unit then links the decided temperature control method to the instrumentation diagram accumulated in a case database. A search processing unit extracts a corresponding instrumentation diagram by searching the case database based on a temperature control method designated as a search condition.Type: GrantFiled: February 7, 2017Date of Patent: January 12, 2021Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Naoya Fukuoka, Hiroki Kawano, Tomooki Ukiana, Toshihiro Mega, Tomohiro Narui, Tomohiro Sato, Hiroto Takahashi

Publication number: 20200394730Abstract: A facility management local server is provided with a proxy work management unit that is communicatively coupled to a proxy management center server. If an error code is output while maintenance work that results in a change in a set value stored in a set value storage unit is being performed in a building to be maintained, the proxy work management unit allows proxy maintenance work to be performed via remote control from a maintenance worker terminal device that is communicatively coupled to the center server. Further, the proxy work management unit can display, on display units provided in the building to be maintained, a proxy request screen including an error code input field and an input field for receiving an input of the content of the maintenance work that was being performed in the building to be maintained when the error code was output.Type: ApplicationFiled: December 14, 2017Publication date: December 17, 2020Applicant: Mitsubishi Electric CorporationInventors: Hiroki KAWANO, Morimasa YOKOTA, Toshihiro MEGA, Naoko HOMMA, Tomooki UKIANA
