Description

The present invention relates to a system that realizes IoT at low cost , for example, by suppressing the cost of IoT devices (sensors, actuators, etc.) that are laid all over the earth.

As background technology related to the system for realizing the IoT at low cost, there were the following, for example. Introduce a border router (gateway device) between the IoT sensor and the server on the Internet, do not set the server address to the sensor, and send the sensor data information to the border router after the own address is confirmed. Send. The border router relays the sensor information to the sensor data management server and collects the data. As a result, the server side can detect the sensor address and also perform pull-type data collection for the sensor address (for example, Patent Document 1).

JP, 2014-78773, A

However, in the case of this background technology, it is possible to collect pull type data addressed to the sensor address from the server side, but each sensor is provided with an internet connection function such as network I/F, or a proprietary standard for connecting to the network. It was necessary to prepare an adapter for, which had the drawback of increasing the cost for realizing the IoT.

On the other hand, some IoT devices that are laid all over the globe do not necessarily need to collect Pull-type data addressed to the sensor address from the server side. For example, in the case of an illuminance sensor installed to collect illuminance throughout the year, the illuminance detection results are stored in memory at regular intervals, and the illuminance collection time is calculated once a year on the server side. It suffices to send the stored illuminance detection result to the server. Further, in the case of an IoT device installed in a place where many humans come and go, a method of transmitting the data of the IoT device to a server by an artificial method using the human being can be considered.

The present invention has been conceived in view of such circumstances, and an object thereof is to provide a system capable of suppressing the cost for realizing the IoT.

The present invention relates to a mobile communication device (for example, a wearable computer, a smartphone, etc.) owned by a user,
A server (for example, the IoT server 8) that communicates with the mobile communication device via the Internet,
With IoT device group,
The IoT device group includes a communication unit (for example, a wireless communication interface unit 22) for communicating with the mobile communication device,
The mobile communication device is
Device-to-device communication means (for example, wireless communication interface unit 36) for communicating with the IoT device group,
Server-to-server communication means (for example, wireless communication processing unit 31) for communicating with the server via the Internet,
Intermediary means (for example, S22, S23, S28, S29) that enables the exchange of information between the IoT device of the communication partner by the device communication means and the server of the communication partner by the server communication means. , S31, S32, S36, S47, S50, S51, S55, S60, S63 to S65, S69, S84, S85, S89, S90, S94).

Preferably, the server further includes privilege granting means (eg, S35, S54, S68, S93) for granting a predetermined privilege to the mobile communication device that has been mediated by the mediating means.
With such a configuration, the user can be provided with an incentive for mediation, and the mediation action of the user can be promoted.

More preferably, the server further includes determination means (for example, S26, S38, S40) for determining whether or not there is an IoT device that needs to exchange information.
With such a configuration, the IoT device group side does not need to have a function of determining whether or not information needs to be exchanged, the processing load on the IoT device group side can be reduced, and the cost can be further suppressed. be able to.

More preferably, the mobile communication device further includes position information transmission means (for example, S22) that transmits information capable of specifying the current position to the server,
The determination unit determines whether or not there is an IoT device that needs to exchange the information in the vicinity of the mobile communication device whose position is specified by the information transmitted by the position information transmission unit ( For example, S26, S38),
When the determination unit determines that the IoT device is present, the server transmits a command signal to the mobile communication device to transmit a command signal to the IoT device by the mediation unit (for example, S27, S39) is further included,
The mediating means mediates according to the command signal from the mediation command transmitting means (for example, S29, S31, S32, S47, S50, S51).
According to such a configuration, the mobile communication device side acts as an intermediary on the IoT device that requires intermediation, and therefore it is not necessary to send an intermediary request signal from the IoT device group side.
More preferably, the mobile communication device includes a notification unit (for example, S71) that notifies the user of the time required for detection by the sensor when performing detection using a sensor that requires a predetermined time for detection. Further includes.
With such a configuration, when it takes a certain amount of time to perform detection, the mobile communication device notifies the user of the required detection time. Therefore, it is possible to cooperate with the collection of the detection data that requires the required time. Can prompt the user.
