  • Publication number: 20240244405
    Abstract: An object of the present invention is to provide a sensor terminal, a data collection unit, a data collection system, a data collection method, and a program capable of handling highly real-time sensing data while eliminating the need to generate a highly reliable timestamp. In a data collection system 302, a sensor terminal 11 receives broadcast time information (step S01), the sensor terminal 11 transmits related time information related to the time information and sensing data as a set (step S02), a data collection unit 12 receives the set (step S03), and the data collection unit 12 organizes the related time information and the sensing data included in the set in a database 12d on the basis of information for identifying the sensor terminal 11 (step S04).

  • Patent number: 11979462
    Abstract: 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 system 301 of the present disclosure is a data collection system that performs communication from a terminal 11 to a data collection unit 12 by a standardized communication protocol (LLDP or HTIP), in which the terminal 11 stores 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 unit 12 associates the sensing data with the metadata based on information for identifying the terminal described in the frame.

  • Publication number: 20240089712
    Abstract: An object is to provide a data collection device and the like capable of reducing a load on an IoT terminal in metadata transmission and power consumption associated with the metadata transmission. In the present invention, a controller is provided on a data collection side that collects metadata, the metadata transmitted from an IoT terminal is grasped, and the IoT terminal is instructed to reduce the transmission frequency of metadata that does not need high real-time property according to a sensor, the type of the IoT terminal, or the like. The IoT terminal transmits the metadata only at a window time (transmission timing, data size, metadata type, or the like) permitted by the metadata controller. As a result, the IoT terminal transmits the metadata only at a limited timing, and thus can reduce a transmission load and power consumption.

  • Patent number: 11929781
    Abstract: An objective is to provide a terminal device, a communication method, and a communication system in which the time taken by connection operations/authentication operations does not increase proportionally with the pattern length, even if the transmitting side and the receiving side are not synchronized. A terminal device, a communication method, and a communication system according to the present invention create n pieces of signal information (n-bit patterns) by sequentially shifting each bit of a single piece of received signal information (n-bit pattern) one bit at a time. Through the above, signal information time-shifted by one bit each is obtained. Thus, even if the transmitting side and the receiving side are not synchronized, one of the n pieces of signal information is a signal synchronized with the transmitting side. Thereafter, the signal synchronized with the transmitting side can be detected by a brute-force calculation with the patterns (ID information) in the list.
