Based on the GPS signal received by the GPS unit 16, the CPU 11 acquires latitude and longitude indicating the current position of the device, and information of height (hereinafter referred to as “position information”).

The sensor unit 17 measures a change in the state of the device as a movement amount. In the present embodiment, the sensor unit 17 is configured of a three-axis geomagnetic sensor and a three-axis acceleration sensor.
The three-axis geomagnetic sensor outputs, for example, three-axis geomagnetic data representing three-axis (X, Y, Z) components of geomagnetism detected using an MI element whose impedance changes according to a change in an external magnetic field. The 3-axis acceleration sensor detects a 3-axis acceleration component with a piezoresistive or capacitive detection mechanism and outputs acceleration data for each 3-axis component. The three-axis components detected by the three-axis acceleration sensor correspond to the three-axis (X, Y, Z) components of the three-axis geomagnetic sensor, respectively.

  In the mobility management device 1 of the present embodiment, position information is intermittently acquired by the GPS unit 16, and when the position information is not acquired by the GPS unit 16, the position detection by the autonomous navigation is performed by the sensor unit 17. Thereby, the power consumption at the time of the positional information acquisition in the GPS part 16 can be restrained, and reduction in power consumption can be realized in the mobility management device 1.

  The input unit 18 includes various buttons and the like, and inputs various information in accordance with a user's instruction operation.

Specifically, the communication unit 21 communicates with the notification device 2 using BLE (Bluetooth Low Energy (trademark)), which is a power saving short distance wireless communication method. The notification device 2 that has communicated with the mobility management device 1 performs notification.

  A removable medium 31 made of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory or the like is appropriately attached to the drive 22. The program read from the removable media 31 by the drive 22 is installed in the storage unit 20 as needed.

FIG. 3 is a functional block diagram showing a functional configuration for executing communication time control processing among such functional configurations of the mobility management device 1.
The communication time control process manages the movement in the movement management device 1 and controls the timing of communication with the notification device 2 according to the movement state, and controls the notification in the notification device 2 It means a series of processing.

  When executing the communication time control process, as shown in FIG. 3, in the CPU 11, the communication control unit 51, the state determination unit 52, the movement management unit 53, the map matching processing unit 54, and the communication time setting unit 55 works.

In addition, in one area of the storage unit 20, a movement plan information storage unit 71 is set.
The movement plan information storage unit 71 stores a map and information (hereinafter, referred to as “movement plan information”) in which a movement path set in advance and a scheduled arrival time and the like are associated with each other.
In the present embodiment, the deviation from the set movement plan and the course-out are determined by map matching between the map in the movement plan information and the current position.
The movement plan information is preset by the user with an external device or the like based on the prepared movement plan, and is stored in the movement plan information storage unit 71.

The communication control unit 51 controls communication with the notification device 2. In the present embodiment, notification is performed in the notification device 2 by communicating with the notification device 2. That is, the timing control of communication becomes the timing control of notification.
The communication control unit 51 also manages the communication time with the notification device 2. Specifically, the communication control unit 51 performs communication in the communication time set by the communication time setting unit 55.
The communication control unit 51 also performs positioning management in the GPS unit 16 such as control of acquisition timing of position information.

  The state determination unit 52 determines the movement state of the device from the acquired sensor value. As the movement state of the device, in the present embodiment, the movement state of climbing walking / downward walking / uphill traveling / downward traveling is determined. Management of a movement plan is performed based on the determined movement state.

  The movement management unit 53 manages the movement state. Specifically, the movement management unit 53 determines the presence or absence of the course out by map matching between the current position and the map of the movement plan information. In addition, the movement management unit 53 calculates the current position and the movement state (climbing / downwalking / climbing / downward traveling) determined by the state determination unit 52, and based on the amount of movement from the current position, the destination The time to reach the event of (hereinafter referred to as "the expected arrival time") is determined. The difference between the estimated arrival time and the event (scheduled arrival time) or the notification time until the event is determined.

  The map matching processing unit 54 maps the current position to the map of the movement plan information stored in the movement plan information storage unit 71. As a result of map matching, it is possible to determine the presence or absence of the current course out and the progress for the previous event.

  The communication time setting unit 55 sets the communication time with the notification device 2. Communication time settings are set by default at 10-minute intervals, and communicate before the expected arrival time based on the estimated arrival time to the event calculated based on the amount of movement from the current position according to the event Set to time. The communication time setting unit 55 is, for example, based on the estimated arrival time calculated from the current position and the movement amount calculated from the current movement state with respect to the estimated arrival time (event) at a predetermined point such as a branch point. Communication time before the event.

FIG. 4 is a flow chart for explaining the flow of communication time control processing executed by the mobility management apparatus 1 of FIG. 2 having the functional configuration of FIG.
The communication time control process is started by the operation of the communication time control process start to the input unit 18 by the user. The communication time control process is started in a state where the movement plan information designed by the user is stored in the movement plan information storage unit 71.

In step S11, the communication control unit 51 determines whether the GPS unit 16 receives GPS positioning information.
When positioning information is received by the GPS unit 16 from the GPS, YES is determined in step S11, and the process proceeds to step S12.

  In step S12, the communication control unit 51 causes the GPS unit 16 to receive GPS positioning information.

  On the other hand, when positioning information is not received by the GPS unit 16 from the GPS, it is determined as NO in step S11, and the process proceeds to step S13.

  In step S13, the sensor unit 17 performs sensor positioning. As a result, sensor values are acquired.

  In step S14, the state determination unit 52 determines the state (climbing / downwalking / uphill traveling / downward traveling) from the acquired sensor value.

  In steps S15 to S19, the movement management unit 53 calculates the movement amount on the basis of the state determined by the state determination unit 52 (climbing / downwalking / uphill traveling / downward traveling).

  In step S20, the map matching processing unit 54 matches the acquired GPS positioning information with the map.

In step S21, the mobility management unit 53 determines whether or not the current position of the mobility plan information on the map is out of course.
If the current position is out of course, YES is determined in step S21, and the process proceeds to step S22.

  In step S22, the movement management unit 53 calculates the distance between the current position and the course on the movement plan information map (course-out distance).

  In step S23, the communication control unit 51 performs course-out notification processing to prepare for notifying that the course is out. With regard to the course out, it is necessary to immediately notify, and the process proceeds to step S26 to communicate with the notification device 2 without waiting for the time of the communication schedule. The processes after step S26 will be described later.

  On the other hand, when the current position is not out of course, it is determined as NO in step S21, and the process proceeds to step S24.

  In step S24, the mobility management unit 53 calculates the remaining distance to the event such as the next branch point or arrival scheduled point.

In step S <b> 25, the communication control unit 51 determines whether it is time to communicate with the notification device 2.
If it is not time to communicate with the notification device 2, it is determined as NO in step S25, and the process returns to step S11.
If it is time to communicate with the notification device 2, YES is determined in step S25, and the process proceeds to step S26.

  In step S26, the communication control unit 51 performs BLE communication processing with the notification device 2, establishes communication, and notification information or the like is sent from the mobility management device 1 to the notification device 2. In the notification device 2, upon receiving communication with the mobility management device 1, various notifications of events such as the next branch point, arrival scheduled point, etc. and unexpected events such as a course out (events Display the content, then make a sound and vibration notification).

In step S27, the mobility management unit 53 determines whether the notification given in step S26 is a goal notification indicating the end of the migration plan.
If it is a goal notification, it is determined as YES in step S27, and the communication time control process is ended.
On the other hand, when it is not the goal notification, the determination is NO in step S27, and the process proceeds to step S28.

In step S28, the mobility management unit 53 converts the movement amount calculated from the current position, and determines whether or not an event such as the next branch point or arrival scheduled point will be passed by the next communication time. .
If it is determined that the event is not passed by the next communication time, NO is determined in step S28, and the process proceeds to step S29.

  In step S29, the communication time setting unit 55 sets the next communication time after 10 minutes which is the default setting. Thereafter, the process returns to step S11.

  On the other hand, when it is determined that the event is passed by the next communication time, YES is determined in step S28, and the process proceeds to step S30.

  In step S30, the communication time setting unit 55 sets the next communication time as the time to be in time for the distance not passing the event from the calculated movement amount to the next communication time. Thereby, communication can be performed and notification can be performed by the notification device 2 before an event starts. Thereafter, the process returns to step S11.

In the conventional positioning device, it is a logging device (trajectory recording device) that records the movement state of the climber, registers the climbing plan in advance, and determines that it is walking on the road according to the climbing plan. There are few devices. In addition, the function of route guidance of car navigation can be considered as a similar technology, but continuous positioning using GPS to realize immediate response is not suitable for low power consumption, Since it is a device that only measures the movement of the position, it is difficult alone to judge the movement of a person and predict and use the next action state.
Therefore, in the communication system S of the present embodiment, the movement management apparatus 1 that determines the logging and movement state, and the notification apparatus 2 that performs notification are configured, and the movement management apparatus 1 measures the movement of a person. In order to sense the behavior of a person using sensors such as acceleration sensors, geomagnetic sensors, barometric pressure sensors, etc., and to determine the state, it is possible to perform any movement when performing any movement. The arrival time to the next branch point is recalculated by determining whether it will be a quantity or measuring the difference between the situation and the mountain planning made in advance, and the location where it is easy to make a mistake By increasing the frequency of positioning and notification, low-consumption operation is possible while keeping high immediate responsiveness.

  Specifically, the communication system S includes a movement management device 1 that consumes less power with two configurations of positioning by GPS and positioning by autonomous navigation during GPS positioning, and a watch type that notifies the movement state From the moving speed when moving along the mountain climbing plan registered in advance in the movement management device 1 in the one to be used as a set with the notification device 2 of FIG. Etc., and when the predicted arrival time arrives earlier than the next communication time, the communication interval is set short to the predicted arrival time, and notification is surely given before the time of arrival at the branch point where it is easy to make a mistake in the road. Configure as. In addition, when it is deviated from the route of the mountain climbing plan at present, communication with the notification device 2 is immediately performed and notification is performed in the notification device 2. The notification device 2 is first configured to notify the user of a road mistake by using sound or light after using a display.

  That is, in the communication system S, when it is determined in the mobility management device 1 that a branch point that is likely to cause a road mistake is approached, notification is given to the notification device 2 that notifies it. For this reason, even if a mistake is made by shortening the interval from a fixed time, notification can be made immediately, and notification can be reliably made, and communication time is longer than that of continuous notification. Since it can be set, low consumption can be realized. As a result, since the battery capacity can be reduced, the device can also be made smaller and lighter.

The communication system S configured as described above includes the notification device 2 and the mobility management device 1 that controls the notification device 2.
The notification device 2 includes an output unit 19-2 that performs notification and a communication unit 21-2 that communicates with the mobility management device 1.
The mobility management device 1 includes a communication unit 21-1 that communicates with the notification device 2, a mobility management unit 53 that acquires location information, and a state determination unit 52 that acquires motion information of the notification device 2. The movement management unit 53 that calculates the movement amount based on the position information acquired by the movement management unit 53 and the movement information of the device acquired by the state determination unit 52, and the movement amount calculated by the movement management unit 53 And the communication time for communicating with the notification device 2 before the estimated time calculated by the movement management unit 53. The communication time setting unit 55 that sets the communication time with the notification device 2 and the communication control that controls the communication unit 21-1 to communicate with the notification device 2 with the communication time set by the communication time setting unit 55 Department 1 and an.
Thereby, in the mobility management device 1, it is possible to surely notify before the event while suppressing the power consumption.

The communication time setting unit 55 sets the communication time to perform communication at predetermined time intervals before the arrival of the event, and based on the estimated time, the communication time is set for the communication time set for the next communication. It is determined whether or not it is passing, and when it is determined that it is passing, the communication time is set at a time interval at which communication will be performed before the estimated time.
Thus, the mobility management device 1 can periodically perform notification while suppressing power consumption, and can reliably perform notification before an event.

The movement management unit 53 calculates the remaining distance based on the calculated movement amount.
Thus, the mobility management device 1 can easily calculate the estimated time.

The scheduled event is a point where notification of a route is required or a point where an arrival time is set.
Thereby, in the mobility management device 1, it is possible to notify the user of necessary information as an event such as a point requiring notification of a route or a point where an arrival time is set.

The movement management unit 53 determines whether or not an event has newly occurred based on the acquired position information.
The communication time setting unit 55 sets the communication time to perform immediate communication when the movement management unit 53 determines that an event has newly occurred.
Thereby, in the mobility management device 1, when an event such as a course out occurs, immediate notification can be performed.

  The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like in the range in which the object of the present invention can be achieved are included in the present invention.

  In the above-described embodiment, the notification device 2 is configured to perform notification by communication from the mobility management device 1. However, for example, the notification time is acquired from the mobility management device 1, and notification is performed based on the notification time. May be configured to

  In the embodiment described above, from the viewpoint of suppressing power consumption, when the function of the notification device 2 (the movement management device 1) is installed in the movement management device 1 (the notification device 2) itself, the steady state notification It is possible to configure so that the notification operation can be surely performed before the event while suppressing the power consumption of the notification operation (the operation of the output unit 19) at the timing.
