To the mobile terminal, a block for executing/releasing suppression of the call incoming on the basis of an instruction to control the call incoming is added. When the person grasps the grip of the wheelchair to push and move the wheelchair, the call incoming is not suppressed. When the wheelchair is accelerated while the grip is not grasped by the person, that is when the wheelchair user rides and operates the wheelchair for himself or herself, the call incoming to the mobile terminal is suppressed.

Description

  The present invention relates to a wireless communication system, a wireless communication apparatus, and a wireless communication apparatus control method for ensuring both safety and convenience when a person using a wheelchair uses a mobile terminal such as a mobile phone. About.

  2. Description of the Related Art Conventionally, many techniques have been devised that prevent the driver of a car from operating a mobile terminal mainly while driving the car and ensure safety. For example, a technology has been devised that detects an operating state of a car and does not accept an incoming call when it is not appropriate to respond to the incoming call even if it is an incoming call using hands-free, such as a back or left / right turn (Patent Document 1). ).

  In addition, the mobile terminal that detects that the car is in operation changes to the restricted mode, and the user cannot operate the mobile terminal by entering a different password each time displayed on the screen. A technique for giving up is also devised (Patent Document 2).

  Furthermore, there is also a technology that restricts the use of a mobile terminal when a weak current flowing from the steering is detected on the mobile terminal side when a driver who holds the steering wheel touches the mobile terminal when a weak current is passed through the steering. It has been devised (Patent Document 3).

  The above-mentioned technology prevents the driver of the car from operating the mobile terminal while driving, and at the same time, enables the passenger or the driver who stopped driving to use the mobile terminal to ensure safety. This technology aims to improve convenience.

  Regarding wheelchairs, it is still dangerous to operate a mobile terminal while driving. However, there are two ways to drive a wheelchair. One is a case where a person who rides in a wheelchair drives the wheelchair, and moves the wheelchair by mainly turning the wheelchair by hand. Another driving method is a method in which a person who is not in a wheelchair, such as a caregiver, holds the wheelchair grip and pushes or pulls the wheelchair.

  In the former case, since the person who rides in the wheelchair himself drives, as in the case of the driver of the car, it is important in terms of ensuring safety to suppress the use of the portable terminal of the person who rides in the wheelchair, that is, the driver. On the other hand, when a caregiver or the like is driving a wheelchair, the person who rides in the wheelchair is no longer a driver, so there is no need to suppress the use of the mobile terminal, and conversely the convenience is impaired.

  The present invention accurately determines whether or not the driver of a wheelchair is a person in a wheelchair, and then determines whether or not to inhibit the use of the mobile terminal.

  A wireless communication system of the present invention includes a first wireless communication unit, a second wireless communication unit, and a notification unit, and a first wireless communication device that receives an incoming call via the first wireless communication unit, A second wireless communication device comprising: a grip detection unit that detects whether or not the user has gripped; an acceleration sensor; and a third wireless communication unit that communicates with the second wireless communication unit. The first wireless communication apparatus receives information related to the grip detection unit and the acceleration sensor via the third wireless communication unit and the second wireless communication unit, and the acceleration sensor moves. When the grip detection unit detects gripping, the notification unit reports the incoming call, detects that the acceleration sensor is moving, and the grip detection unit detects gripping. If not detected, the notification unit does not notify the incoming call. The notification unit notifies the user of an incoming call by generating sound, vibration, or light.

  With this configuration, the first wireless communication device detects that the acceleration sensor of the second wireless communication device is moving and the incoming notification by the notification unit only when the grip detection unit detects gripping. If the acceleration sensor detects that the sensor is moving, and the grip detection unit does not detect gripping, the incoming call is not notified so that the part including the grip detection unit is gripped during movement. By notifying the incoming call only in a state where the wireless communication device is present, it is possible to eliminate the trigger for operating the wireless communication device only in a state that is not suitable for operating the wireless communication device for safety reasons.

  Further, in the wireless communication system of the present invention, when the acceleration sensor detects that it is moving and the grip detection unit does not detect grip, it does not return a response to the call signal from the wireless communication network. If the notification unit rejects the incoming call and the notification unit does not notify the incoming call or detects that the acceleration sensor is moving when a call is received and the grip detection unit does not detect gripping, the incoming call is accepted. By notifying the caller of a voice message indicating that the call cannot be answered, and notifying the caller that the notification unit does not notify the incoming call, it is possible to notify the caller that the response is impossible. .

  In the wireless communication system of the present invention, the incoming call is an incoming mail or incoming call, and when the acceleration sensor detects movement and the grip detection unit detects grip, the notification unit When a mail incoming call or the telephone incoming call is notified, and it is detected that the acceleration sensor is moving, and the grip detection unit does not detect gripping, the notification unit notifies the mail incoming call and notifies the telephone incoming call. By not receiving incoming calls, it is possible to improve convenience by notifying only about incoming mails that do not require immediate response.

  In the wireless communication system of the present invention, when it is detected that the acceleration sensor is moving and the grip detection unit does not detect grip, the incoming call is rejected, and the notification unit is the mail An incoming call is notified and the incoming call is not notified.

  In the wireless communication system of the present invention, the second wireless communication device is attached to a grip of a wheelchair provided with a grip held by an assistant, and is removable, so that a person driving the wheelchair can Incoming calls when driving a wheelchair are suppressed, and it is possible to allow incoming calls when an assistant is driving. In addition, when changing to a different wheelchair, it is possible to respond immediately.

  In the wireless communication system of the present invention, the second wireless communication device includes an input unit for inputting whether or not to hold the incoming call, and the first wireless communication device includes the third wireless communication unit. And receiving information related to the input unit via the second wireless communication unit, detecting that the acceleration sensor is moving and the grip detection unit does not detect gripping, or the input When it is input that the incoming call is put on hold in the unit, the notification unit does not notify the incoming call, so that when the assistant pushes the wheelchair to drive, the incoming call can be made at the assistant's judgment.

  In the wireless communication system of the present invention, the grip detection unit detects grip grip using a pressure-sensitive sensor or an electrostatic sensor.

  The wireless communication device of the present invention is a wireless communication device that includes a first wireless communication unit, a second wireless communication unit, and a notification unit, and receives an incoming call via the first wireless communication unit. When the external acceleration sensor detects that the external acceleration sensor is moving and the external grip detection unit detects gripping, the notification unit notifies the incoming call, and the external acceleration sensor is moving. When the external grip detection unit does not detect gripping, the notification unit does not notify the incoming call.

  The wireless communication device of the present invention is a wireless communication device that includes a grip detection unit that detects whether or not a person has gripped, an acceleration sensor, and a wireless communication unit, via the wireless communication unit. Information related to the grip detection unit and the acceleration sensor is transmitted.

  Further, the wireless communication device control method of the present invention includes an incoming call detection step for detecting an incoming call, a movement detection step for detecting whether or not it is moving, a grip detection step for detecting whether or not it is gripped by a person, If it is detected that the movement is detected in the movement detection step, and the grip is detected in the grip detection step, the incoming notification step of notifying the incoming call is detected, and the movement detection step is detected. And an incoming call non-notification step in which the incoming call is not notified when gripping is not detected in the grip detection step.

  By switching the incoming call notification at the time of movement depending on whether or not it is gripped by these steps, it is possible to ensure both safety at the time of movement and improvement of convenience.

  According to the present invention, the first wireless communication device detects that the acceleration sensor of the second wireless communication device is moving and the incoming notification by the notification unit only when the grip detection unit detects gripping. If the acceleration sensor detects that the sensor is moving, and the grip detection unit does not detect gripping, the incoming call is not notified so that the part including the grip detection unit is gripped during movement. By notifying the incoming call only in a state where the wireless communication device is present, it is possible to eliminate the trigger for operating the wireless communication device only in a state that is not suitable for operating the wireless communication device for safety reasons.
