  • Patent number: 10080357
    Abstract: In an insect pest attraction lighting system which irradiates a field with attraction light for attracting insect pests to keep the insect pests away from a plant, an effect of protection against diurnal insect pests is improved. An insect pest attraction lighting system 1 includes: a setting unit 2 which sets, as an operating time zone, an arbitrary time zone during nighttime; an artificial sunlight source unit 3 which irradiates the entirety of an interior of a plastic greenhouse H1 with artificial sunlight which does not include wavelength components of 500 to 600 nm, in the operating time zone; and an attraction light source unit 4 which irradiates a portion of the interior of the plastic greenhouse H1 with attraction light in the operating time zone.

  • Patent number: 9146927
    Abstract: A data receiving part receives data transmitted from a plurality of measuring devices. A time determining part distinguishes management time from date and time of the data. The record generating part stores data of the same management time which are received during a predetermined acceptance time, in the same record. When un-arrived data belonging to the same management time exists at the end of the acceptance time, arrival of the un-arrived data is waited for during a predetermined wait time. Even if the data is arrived with some delay, arrival-delayed data can be stored in the same record. Thus, the missing data occurrence frequency can be suppressed.

  • Publication number: 20110307488
    Abstract: A behavior index indicates a development of occurrence of events included in log data by a connection of a plurality of nodes, and includes a branching node connecting to two or more subsequent nodes and an integrating node connected to two or more preceding nodes. When a regular expression converting part inputs a search condition indicating an event appearance order from a client, a search automaton retaining part generates a state transition table in accordance with the search condition. While a node type determining part determines the node types of the respective nodes of the behavior index, a state evaluating part analyzes the respective nodes to determine the states of the respective nodes, and determines whether or not a state transition pattern matches the state transition table. Regarding a branching node, the respective nodes of each of branching routes branching from the branching node are analyzed.

  • Publication number: 20110078218
    Abstract: When an instance targeted for tracking is divided or replicated to generate a new instance, ready and continuous tracking of a history of an event related to the original instance and the new instance is allowed. A behavior ID is assigned to an event for each instance, and an occurrence order of the event is managed for each instance. When a new instance has been generated from an instance due to a certain event, a new behavior ID is assigned to the new instance, with respect to that event. Then, the new identifier and an identifier assigned to the instance that is a generation source for the event are associated.

  • Patent number: 7269466
    Abstract: The present invention aims to control elements to improve operation efficiency of a plant based on a correlation value of the past accumulated data. According to the invention, an optimal operation controller obtains a correlation between a state of a predetermined process and each element based on an operation status of the plant to be controlled, storing the correlation in a correlation table, and compute an operation efficiency for each element based on the operation status of the plant. Also, the operation controller has a categorization efficiency table for storing the computed operation efficiency of the predetermined process. The operation controller refers to the categorization efficiency table based on a data input from the plant, and outputs an instruction to control the each element accordingly.
