As a result, the altitude is output from the measured air pressure.

  The altitude correction module 20 subtracts the atmospheric pressure correction information (atmospheric pressure correction value which is an altitude error other than the altitude change) stored in the atmospheric pressure correction information from the altitude obtained by inputting the measured atmospheric pressure value to the atmospheric pressure altitude conversion module. Correct the altitude by

FIG. 2 is a functional block diagram showing a functional configuration for executing the advanced acquisition process among the functional configurations of such a portable electronic device 1.
The altitude acquisition process is a series of processes for acquiring the altitude based on the positioning information measured from the GPS, the measurement information of the barometric pressure, and the barometric pressure correction information.

  In the case of executing the altitude acquisition process, as shown in FIG. 2, the drive control unit 51 and the altitude acquisition processing unit 52 function in the CPU 11.

  Further, in one area of the storage unit 23, a setting information storage unit 71, an atmospheric pressure / altitude conversion table storage unit 72, an atmospheric pressure correction information storage unit 73, and an altitude information storage unit 74 are set.

  The setting information storage unit 71 stores GPS intermittent reception times and the like, which are drive timings of the GPS.

  The atmospheric pressure elevation conversion table storage unit 72 stores an atmospheric pressure altitude conversion table for changing the atmospheric pressure to a high level according to a predetermined standard (in the present embodiment, the international standard atmosphere (ISO 2533: 1975)).

  The atmospheric pressure correction information storage unit 73 stores atmospheric pressure correction information including an atmospheric pressure correction value.

  The drive control unit 51 compares the various setting times stored in the setting information storage unit 71 with the current time acquired from the clock unit 16 and controls the GPS module 17 to operate intermittently at a predetermined timing.

The altitude acquisition processing unit 52 performs processing relating to calculation of the altitude.
Specifically, the altitude acquisition processing unit 52 acquires altitude (hereinafter referred to as “positioning altitude”) from the GSP positioning information output from the GPS module 17 as a result of driving.

  Further, the altitude acquisition processing unit 52 converts the measured pressure value measured by the pressure measurement module 18 with reference to the pressure / altitude conversion table stored in the pressure / altitude conversion table storage unit 72 in the pressure / altitude conversion module 19.

Further, the altitude acquisition processing unit 52 calculates a difference value between the positioning altitude and the barometric altitude (hereinafter referred to as “barometric pressure correction value”), and stores it in the barometric pressure correction information storage unit 73 as barometric pressure correction information.
Since the barometric pressure changes not only with the change in altitude but also with the change in weather, in order to obtain an accurate altitude, it is necessary to subtract the change in barometric pressure due to causes other than the change in altitude from the measured pressure value. For this reason, in the portable electronic device 1 of the present embodiment, an accurate altitude is acquired using barometric pressure correction information which is an altitude error component based on a barometric pressure change due to, for example, weather other than the altitude change.

  Further, the altitude acquisition processing unit 52 stores the atmospheric pressure correction information (altitude change stored in the atmospheric pressure correction information storage unit 73 from the altitude obtained by inputting the measured atmospheric pressure value to the A corrected accurate altitude is obtained by subtracting the atmospheric pressure correction value, which is an error error other than the above.

  The method of using the air pressure correction information in the altitude correction module 20 is stored in the air pressure correction information storage unit 73 instead of simply selecting the latest air pressure correction information stored in the air pressure correction information storage unit 73. From the plurality of barometric pressure correction information, for example, a prediction equation as a first-order approximation formula is created by the least square method, the current barometric pressure correction information is predicted from this prediction equation, and the altitude correction processing is performed using this prediction value. It can also be configured to obtain more accurate altitude information.

  Further, the air pressure correction information can be calculated not as an altitude error but as an air pressure error. That is, the converted barometric pressure value is calculated by referring to the barometric height conversion table stored in the barometric height conversion table storage unit 72 in reverse by the altitude information obtained from the GSP positioning information, and comparing this with the measured barometric pressure value, The difference value is taken as pressure correction information. In that case, the altitude correction module 20 subtracts the atmospheric pressure error which is the atmospheric pressure correction value of the atmospheric pressure correction information storage unit 73 from the measured atmospheric pressure value, and inputs it to the atmospheric pressure altitude conversion module 19 to acquire accurate altitude information. It can also be configured.

The advanced acquisition process is started by the user's operation of starting the advanced acquisition process on the input unit 21.

  In step S11, the drive control unit 51 compares the various setting times stored in the setting information storage unit 71 with the current time acquired from the time measuring unit 16 and operates the GPS module 17 intermittently at a predetermined timing. Control.

  In step S12, the altitude acquisition processing unit 52 acquires a positioning altitude from the GSP positioning information output from the GPS module 17 as a result of driving.

  In step S13, the altitude acquisition processing unit 52 converts the measured pressure value measured by the pressure measurement module 18 with reference to the pressure / altitude conversion table stored in the pressure / altitude conversion table storage unit 72 in the pressure / altitude conversion module 19. Get the barometric pressure altitude.

  In step S14, the altitude acquisition processing unit 52 calculates a barometric pressure correction value by calculating the difference between the positioning height and the barometric pressure height, and stores the calculated barometric pressure correction information in the barometric pressure correction information storage unit 73.

In step S15, the altitude acquisition processing unit 52 stores the atmospheric pressure correction information stored in the atmospheric pressure correction information storage unit 73 from the altitude obtained by the altitude correction module 20 inputting the measured atmospheric pressure value to the The calculated accurate altitude is obtained by subtracting the barometric pressure correction value which is an altitude error other than the altitude change. Then, the height acquisition processing unit 52 stores the calculated height in the height information storage unit 74.
Thereafter, the advanced acquisition process ends.

[Operation with multiple mobile electronic devices]
As described above, although it is possible to obtain advanced equipment alone, in order to improve the accuracy and reduce power consumption, the following system (advanced acquisition system) is constructed to provide each portable electronic device Acquire the altitude at 1. In addition, below, the example in the case of calculating an altitude in three portable electronic devices 1A, 1B, and 1C is demonstrated. The portable electronic devices 1A, 1B, and 1C are paired in advance by BLE communication, and one-to-one near-field wireless communication can be performed between the portable electronic devices 1A, 1B, and 1C.

First Embodiment
In this embodiment, each portable electronic device 1A, 1B, 1C does not generate GPS reception / pressure correction information by itself, in order to reduce power consumption in GPS reception of the entire constructed system. The GPS reception / pressure correction information is generated by the device 1, and the generated pressure correction information is used by the other portable electronic device 1. In addition, if GPS reception is performed only with one portable electronic device 1, power consumption will be uneven, so GPS reception may be performed around the mobile electronic devices 1 A, 1 B, and 1 C configuring the system (cyclically). Configure to do.

  First, in each portable electronic device 1, the device ID and the total number of devices for communication management are set by the operation through the input unit 21 of the user.

FIG. 4 is a diagram showing settings in communication management at the time of operation of a plurality of portable electronic devices 1. In the figure, the portable electronic device 1A is displayed as the device A, the portable electronic device 1B is displayed as the device B, and the portable electronic device 1C is displayed as the device C.
Specifically, as shown in the example of FIG. 4, the portable electronic devices 1A, 1B, and 1C are {device ID = 0, number of devices = 3}, {device ID = 1, number of devices = 3}, {one The device ID = 2 and the number of devices = 3} are set.

  Thus, it is possible to identify the electronic device of the transmission source and determine whether the portable electronic device transmitted from the number of electronic devices is the final electronic device of transmission. For example, when the device A with the device ID = 0 is the transmission source of information, the device C with the device ID = 2 determines that it is the final electronic device from the device ID = 0 and the number of devices = 3. Can. Then, the portable electronic device 1C transmits the received information to the portable electronic device 1A in which the electronic device ID = 0. Thereafter, by receiving the same information from the final electronic device, the mobile electronic device 1A can determine that communication between electronic devices (intercommunication) is not a problem.

  In this embodiment, in the one-to-one BLE communication, the information transmitted from a predetermined portable electronic device is sequentially delivered to all the portable electronic devices, and the electronic device is received by receiving the information transmitted from the final electronic device. It is communication which completes communication between. Therefore, the information transmitted from a predetermined portable electronic device will be sequentially acquired by other portable electronic devices.

When the setting of the electronic device is performed as described above, the following operation is performed.
FIG. 5 is a diagram for explaining the operation of advanced acquisition in a plurality of portable electronic devices 1 according to the first embodiment. In the figure, the portable electronic device 1A is displayed as the device A, the portable electronic device 1B is displayed as the device B, and the portable electronic device 1C is displayed as the device C.

  First, the processing start time and the intermittent reception interval (for example, 10 minutes) in the portable electronic device (in the present embodiment, the portable electronic device 1A) to start the processing are set. The set processing start time and the intermittent reception interval are transmitted as intermittent reception information to the portable electronic device 1B and the portable electronic device 1C, which are other portable electronic devices other than the portable electronic device 1A, by mutual communication.

  Then, by receiving the same information transmitted from the portable electronic device 1A from the portable electronic device 1C which is the final electronic device, it is determined that communication between electronic devices (intercommunication) is not a problem, and processing such as GPS reception is performed. Start.

  The measurement start time t0 is determined in consideration of the communication time of the first GPS intermittent reception information. In this way, when all the portable electronic devices share the measurement start time t0 and the GPS intermittent reception timing T, each portable electronic device can set its own GPS intermittent reception time and the atmospheric pressure correction information communication time.

That is, each portable electronic device sets the GPS intermittent reception time and the air pressure correction information communication time at the following timing.
The air pressure correction information communication time is set to t = t0 + n * T (n = 0, 1, 2...) Common to all the electronic devices.
The GPS intermittent reception time of the portable electronic device 1A is set as ta = t0 + n0 * T (n0 = 0, 3, 6, 9...).
The GPS intermittent reception time of the portable electronic device 1B is set as tb = tp + n1 * T (n1 = 1, 4, 7, 10...).
The GPS intermittent reception time of the portable electronic device 1C is set as tc = tp + n2 * T (n1 = 2, 5, 8, 11...).
Therefore, the timing of intermittent reception of each portable electronic device will be 3 * T.

  By setting the GPS intermittent reception time and the air pressure correction information communication time in all the portable electronic devices, when the operation of the GPS intermittent reception is started, the following processing is executed.

  First, at time ta, the portable electronic device 1A performs GPS intermittent reception, calculates barometric pressure correction information from the acquired positioning altitude and the barometric altitude at that time, transmits it to the portable electronic device 1B, and the portable electronic device 1B further The same information is transmitted to the portable electronic device 1C, and the portable electronic devices 1A, 1B, and 1C store the pressure correction information at time ta.

  Next, at time tb, the portable electronic device 1B receives GPS intermittent reception, calculates atmospheric pressure correction information from the atmospheric pressure height at that time, and transmits it to the portable electronic device 1C, and further the portable electronic device 1C to the portable electronic device 1A The same information is transmitted, and the portable electronic devices 1A, 1B, and 1C store the pressure correction information at time tb.

  Next, at time tc, the portable electronic device 1C receives GPS intermittent reception, calculates barometric pressure correction information from the acquired positioning altitude and the barometric altitude at that time, transmits it to the portable electronic device 1A, and the portable electronic device 1A further The same information is transmitted to the portable electronic device 1B, and the portable electronic devices 1A, 1B, and 1C store the pressure correction information at time tc.

  Thus, in each of the portable electronic devices 1A, 1B, and 1C, the pressure correction information is stored for each time interval T.

  At the time of GPS non-reception, it is possible to obtain accurate altitude information from which the altitude error due to the atmospheric pressure change other than the altitude change is removed by using the atmospheric pressure correction and the atmospheric pressure correction information for each time interval T.

  If the reception situation is not good due to GPS intermittent reception at the set timing and the positioning altitude is not obtained, a primary prediction equation is created from the past barometric pressure correction information stored in the barometric pressure correction information storage unit 73, The atmospheric pressure correction predicted value obtained from the prediction equation is transmitted as atmospheric pressure correction information at that time.

Next, among the functional configurations of the plurality of portable electronic devices 1 in the first embodiment, a functional configuration for executing the advanced acquisition process will be described. In the following, the description of the same functional configuration as the single operation is omitted.

  Further, in one area of the storage unit 23, a setting information storage unit 71, an atmospheric pressure / altitude conversion table storage unit 72, an atmospheric pressure correction information storage unit 73, and an altitude information storage unit 74 are provided.

  The setting information storage unit 71 of each portable electronic device 1 stores an electronic device ID, the number of electronic devices, a set GPS intermittent reception time, a measurement start time, and an atmospheric pressure correction information communication time.

  The mutual communication setting unit 53 sets the electronic device ID and the number of electronic devices by the setting operation by the user via the input unit 21. Further, the mutual communication setting unit 53 corrects the atmospheric pressure from the GPS intermittent reception time, the GPS intermittent reception time, and the measurement start time by the setting operation by the user via the input unit 21 or the data reception from the other portable electronic device 1. Set the information communication time. The set electronic device ID, the number of electronic devices, the GPS intermittent reception time, the measurement start time, and the air pressure correction information communication time are stored in the setting information storage unit 71.

  The communication control unit 54 controls the communication unit 24 to transmit the set GPS intermittent reception time and the atmospheric pressure correction information communication time to the other portable electronic device 1.

Next, the flow of the altitude acquisition process executed by the mobile electronic device 1 in the first embodiment will be described.

That is, based on the barometric pressure correction information generated by the portable electronic device 1 of the transmission source, the received atmospheric pressure correction information is transmitted to the other portable electronic device 1 (steps S132 and S133). Step S131). At the time of transmission to the other portable electronic device 1, the electronic device ID of the own device is also sent together, and if it is the final electronic device based on the electronic device ID and the number of electronic devices, that effect is sent together . As a result, in all the portable electronic devices 1, reception of the air pressure correction information and acquisition of the altitude will be performed.

  In the present embodiment, in the portable electronic device 1 related to GPS intermittent reception, power consumption related to GPS intermittent reception in the entire system configured with a plurality of portable electronic devices 1 can be suppressed because it is performed only once. . In addition, by performing BLE communication in the communication unit 24 only at the air pressure correction information communication time common to all the portable electronic devices 1, it is possible to suppress the power consumption related to the acquisition of the air pressure correction information.
