Abstract

A data acquisition unit repeatedly acquires pieces of notification information for executing predetermined processing from respective BLE devices. A connection controller detects a BLE device, calculates digitalized values of influences of the respective pieces of notification information acquired from the respective BLE devices on the predetermined processing on the basis of the pieces of notification information already acquired by the data acquisition unit, selects a BLE device on the basis of the calculated digitalized values of the influences, and causes the data acquisition unit to stop acquisition of the notification information from the selected BLE device and establishes connection with the BLE device.

Claims

1. A communication control device comprising:

a data acquisition unit that repeatedly acquires pieces of notification information for executing predetermined processing from a plurality of terminal devices; and

a connection controller that detects a specific connectible terminal device, calculates digitalized values of influences of the respective pieces of notification information acquired from the respective terminal devices on the predetermined processing on the basis of the pieces of notification information already acquired by the data acquisition unit, selects a terminal device on the basis of the calculated digitalized values of the influences, and causes the data acquisition unit to stand by for acquisition of the notification information from the selected terminal device and establishes connection with the specific terminal device.

2. The communication control device according to claim 1, wherein

the data acquisition unit acquires communication states with the respective terminal devices as transmission sources of the respective pieces of notification information in acquisition of the respective pieces of notification information, and

the connection controller calculates the digitalized values of the influences on the basis of the pieces of notification information and the communication states already acquired by the data acquisition unit.

3. The communication control device according to claim 1, wherein the connection controller selects the terminal device from which the notification information is acquired at closest timing among the terminal devices having the digitalized values of the influences that are equal to or lower than a threshold.

4. The communication control device according to claim 1, wherein the connection controller determines whether connection of the specific terminal device is reconnection, and when the connection is the reconnection, the connection controller calculates a specific digitalized value of the influence of the notification information that is acquired from the specific terminal device on the predetermined processing on the basis of the notification information already acquired by the data acquisition unit and selects the terminal device using the specific value.

5. The communication control device according to claim 1, wherein the data acquisition unit acquires the notification information from the specific terminal device after the connection controller establishes the connection with the specific terminal device.

6. A communication control system comprising a communication control device, a plurality of terminal devices, and a processing execution device, wherein

each of the terminal devices includes:

an acquisition unit that repeatedly acquires notification information, and

a transmitter that transmits the notification information acquired by the acquisition unit to the communication control device,

the processing execution device executes predetermined processing using the pieces of notification information transmitted from the respective terminal devices, and

the communication control device includes;

a data acquisition unit that acquires the pieces of notification information from the respective terminal devices, and

a connection controller that detects a specific connectible terminal device, calculates digitalized values of influences of the respective pieces of notification information acquired from the respective terminal devices on the predetermined processing on the basis of the pieces of notification information already acquired by the data acquisition unit, selects a terminal device on the basis of the calculated digitalized values of the influences, and causes the data acquisition unit to stand by for acquisition of the notification information from the selected terminal device and establishes connection with the specific terminal device.

7. A communication control method comprising:

acquiring pieces of notification information for executing predetermined processing from a plurality of terminal devices;

detecting a specific connectible terminal device;

calculating digitalized values of influences of the respective pieces of notification information acquired from the respective terminal devices on the predetermined processing on the basis of the pieces of already acquired notification information;

selecting a terminal device on the basis of the calculated digitalized values of the influences;

standing by for acquisition of the notification information from the selected terminal device and establishing connection with the specific terminal device; and

acquiring the pieces of notification information from the respective terminal devices and the specific terminal device.
