A server device includes a determination unit and a control unit. The determination unit determines the degree of congestion of a communication network on the basis of a difference between the time difference, between the transmission time and the reception time of sensor data transmitted from a gateway device to the server device, and the communication period of time taken in a state where congestion does not occur. The control unit determines a sensor device from which sensor data is collected and a sensor device in which collection of sensor data is withheld on the basis of the determination result of the degree of congestion of the communication network, and sends an instruction including the determined content to the gateway device.

A system is provided that includes: a first relay device provided on a first network hierarchy level; and a second relay device provided on a second network hierarchy level higher than the first network hierarchy level. The first relay device includes: a first information reception unit that receives target object information about a target object, transmitted by a radio tag attached to the target object in accordance with a predetermined timing; a first information storage unit that stores the target object information received by the first information reception unit; a first change determination unit that determines whether there has been a change in a status of the target object, based on a status of reception of the target object information; and a first information transmission unit that transmits the target object information to the second relay device, when the first change determination unit determines that there has been the change.

A physical quantity detection device includes a sensor element that generates a detection signal of the physical quantity and a conversion circuit that converts the detection signal generated by the sensor element into an output signal. The conversion circuit includes a set number of output units each corresponding to a respective one of a set number of communication methods, each of the output units being capable of generating the output signals conforming to their corresponding communication method, the set number being two or more, a storage unit that stores method specifying information which specifies a communication method, to be applied to the mounting target, among the set number of communication methods, and a selection unit that selects an output unit, which outputs the output signal, among the set number of output.

To enable necessary information to be obtained from a sensor when necessary. An information processing device includes a processing unit including a memory, a sensing unit, a condition storage unit configured to store a condition for outputting a situation value indicating a state according to a situation in which the information processing device is disposed, a determination unit configured to determine whether the condition is satisfied, a situation value calculation unit configured to calculate the situation value based on a measured value acquired by the sensing unit, and an output unit configured to output the situation value when the condition is satisfied.

A measurement result receiving apparatus receives measurement results transmitted from a plurality of measuring devices, the measurement results obtained by conducting a measurement at a predetermined sampling interval according to a reference clock of each measuring device. The measurement result receiving apparatus includes a receiving section that receives the measurement results from the plurality of measuring devices; and a sampling interval converting section that converts the measurement results into measurement values associated with a common sampling interval.

A communication cell may receive a request to establish a communication session for delivery to a core network of carrier network, the request originating from a user device connected to the communication cell. A lookup table stored in the communication cell is populated with an association of a session identifier assigned to the communication session and a caller identifier of the user device. The request is placed into an uplink buffer portion of the communication cell that is set aside for the user device. The request is encoded into one or more physical resource blocks reserved for the communication cell by a macrocell, the physical resource blocks being a part of a wireless in-band backhaul between the communication cell and the macrocell. The one or more physical resource blocks that include the request from the communication cell are then transmitted to the macrocell for delivery to the core network.

A data converter, a signal transmission method, and a signal transmission system for transmitting a signal to a programmable logic controller are provided. The data converter: performs sampling multiple times with respect to data detected by a sensor in one communication period of communication with a programmable logic controller; acquires statistical data by statisticizing a plurality of sampling data in the communication period; and transmits the statistical data to the programmable logic controller when the communication period is reached. On the basis of an embodiment of the present invention, a signal sampling density is improved, and thus control accuracy can be enhanced. At the same time, a data transmission amount of a bus is reduced, a load on the programmable logic controller is reduced, and user convenience is improved.
