A location information transmitter transmits location information within a prescribed area. An IoT terminal receives the location information and transmits the location information and a device identifier. An address setting management device receives the location information and the device identifier and sets an IP address to be assigned to the IoT terminal on the basis of the location information and the device identifier and transmits the IP address to the IoT terminal. The IoT terminal sets the IP address received from the address setting management device for itself.

Address setting system, address setting method, address setting management device and program

The present disclosure provides a monitoring system including an edge processing apparatus including a space distinct ID management database, a space distinct ID control unit, a storage unit, an analysis unit, and an abnormality determination unit, and a controller, a transmitter, and a camera with sensor that are installed in a location to be monitored, in which the space distinct ID management database stores a space distinct ID and a transmission time of the space distinct ID in association with the location to be monitored, the space distinct ID control unit acquires the space distinct ID associated with the location to be monitored from the space distinct ID management database and transmits the space distinct ID that is acquired to the controller in the associated location to be monitored, the controller transmits the space distinct ID acquired from the space distinct ID control unit to the transmitter, the transmitter generates a signal based on the space distinct ID acquired from the controller and diffuses, in a space of the location to be monitored, the signal that is generated, the camera with sensor includes a sensor that captures an image of the location to be monitored where the camera with sensor is installed and receives the signal diffused by the transmitter, and the camera with sensor transmits a received signal received by the sensor to the storage unit, the storage unit stores the received signal received from the camera with sensor in association with the location to be monitored where the camera with sensor is installed, the analysis unit extracts a space distinct ID from the received signal stored in the storage unit and transmits the space distinct ID that is extracted to the abnormality determination unit in association with the location to be monitored, and the abnormality determination unit compares and determines whether there is a match between the space distinct ID associated with the location to be monitored from the analysis unit and current time, and the space distinct ID and the transmission time of the space distinct ID associated with the location to be monitored that are stored in the space distinct ID management database.

Monitoring system, monitoring method, and monitoring program

An object of the present disclosure is to provide a data collection system capable of collecting various pieces of metadata other than sensing data and instrument information by existing communication protocols and associating the sensing data, the instrument information, and the metadata with each other without errors. A data collection systemis a data collection system that performs communication from a terminalto a data collection unitby one or a plurality of communication protocols, in which the terminalincludes a detection unitother than a sensor devicethat detects the sensing data and the instrument information, and stores metadata that is information detected by the detection unitin an extended field specified by the communication protocols within a frame specified by the communication protocols for transmitting the sensing data or the instrument information, and the data collection unitassociates the sensing data, the instrument information, and the metadata with each other based on information for identifying the terminaldescribed in the frame.

Data collection system and data collection method

An object of the present disclosure is to collectively collect sensing data and metadata regarding normality of equipment by utilizing light communication protocol. The present disclosure is a system that collects sensing data from a sensor terminal in a data collection unit using a data collection network, the sensor terminal including a detection unit configured to detect metadata regarding internal information of the sensor terminal other than a sensor device that detects sensing data and equipment information and transmitting the metadata detected by the detection unit using an extended area or an optional area defined in communication protocol for transmitting the sensing data or the equipment information in a frame defined in the communication protocol, and the data collection unit associating the sensing data, the equipment information, and the metadata on the basis of information for identifying the sensor terminal described in the frame.

Systems and methods for collecting metadata and sensor terminals

An object of the present disclosure is to provide a data collection system and a data collection method which are capable of collecting sensing data and various pieces of metadata by a single communication protocol and capable of associating the sensing data with the metadata without errors. A data collection systemof the present disclosure is a data collection system that performs communication from a terminalto a data collection unitby a standardized communication protocol (LLDP or HTIP), in which the terminalstores sensing data detected by a sensor device in an extended field different from a field in which metadata is stored, within a frame specified by the communication protocol, and the data collection unitassociates the sensing data with the metadata based on information for identifying the terminal described in the frame.

An object of the present disclosure is to enable reduction of network congestion and concentration of communication on a server side that locally occur at the time of a disaster, an event, or the like and to enable important communication. A communication network control system according to the present disclosure includes: a plurality of communication control devices () that control communication of apparatuses (); and a central communication control device () that distributes communication control information to the plurality of communication control devices, the central communication control device () collects event information linked to position information, determines an area with a probability that the amount of communication increases, using the collected event information, in a case in which there is an area with the probability that the amount of communication increases, generates communication control information that places a priority on communication in the area, and distributes the generated communication control information to the plurality of communication control devices ().
