In the third embodiment, an example will be described in which the electronic timepiece includes a configuration for receiving satellite radio waves and various sensors. In the following description, it is assumed that the smartphone and the electronic timepiece are paired (mutual authentication) in advance.

(First embodiment)
As shown in FIG. 1, the communication system 1 according to the first embodiment of the present invention includes a smartphone 100 that is a wireless communication device and an electronic timepiece 200 that is another wireless communication device different from the smartphone 100.

The smartphone 100 and the electronic timepiece 200 perform short-range wireless communication with each other based on Bluetooth (registered trademark) low energy (hereinafter referred to as BLE). BLE is a standard (mode) established for the purpose of low power consumption in a short-range wireless communication standard called Bluetooth (registered trademark).

The smartphone 100 operates as a central that receives the advertisement packet based on BLE. The electronic timepiece 200 operates as a peripheral that transmits an advertisement based on BLE. Further, during wireless communication after the connection between the smartphone 100 and the electronic timepiece 200 is established, the smartphone 100 operates as a master and the electronic timepiece 200 operates as a slave.

The smartphone 100 receives radio waves from the satellite 40. The satellite 40 is, for example, a satellite used for positioning such as GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System).

The smartphone 100 also communicates with other devices connected to a WAN (World Area Network) 50 via a relay device, an access point, and the like, which are not shown. Other devices are provided with a plurality of NTP (Network Time Protocol) servers 10 that provide time information, an NTP pool (Network Time Protocol-Pool) server 20, and information indicating the position (latitude and lightness) of the communication terminal. The location server 30 and the map information distribution server 60 that provides map information are included.

The NTP pool server 20 receives an access from a communication terminal and inquires the IP (Internet Protocol) of the communication terminal with a position database, thereby specifying the position of the communication terminal. The NTP pool server 20 allocates the NTP server 10 in the area corresponding to the position of the communication terminal among the plurality of NTP servers 10. Normally, a plurality of (for example, four) NTP servers 10 are allocated. The communication terminal receives the NTP packet from the assigned NTP server 10 and acquires the time.

Here, the reference of "time" in the present embodiment is UTC (Universal Time Coordinated) time. However, the reference of "time" is not limited to the UTC time, and may be any information indicating standard time or information serving as a reference of time. For example, the reference of “time” may be GMT (Greenwich Mean Time) time. Further, the “time” in this embodiment includes not only the hour and minute but also the date.

The configuration of the smartphone 100 according to this embodiment will be described below. As shown in FIG. 2, the smartphone 100 includes a communication device 190 and a display unit 170. The communication device 190 includes a communication unit 110, a short-range wireless communication unit 120, a satellite radio wave reception unit 130, a RAM (Random Access Memory) 140, a ROM (Read Only Memory) 150, an operation unit 160, and a control unit. 180. These components of the communication device 190 and the display unit 170 are connected to each other by a bus line BL.

The communication unit 110 includes, for example, a radio frequency (RF) circuit, a base band (BB) circuit, an integrated circuit (LSI: Large Scale Integration), and the like. The communication unit 110 performs wireless communication with a relay device, an access point, etc. via the antenna 111. The communication unit 110 is connected to the WAN 50 via a relay device, an access point, etc., and communicates with the NTP server 10, the NTP pool server 20, the location server 30, and the map information distribution server 60. The communication unit 110 may be configured to be connected to the WAN 50 by wire communication and communicate with other devices, instead of being configured to wirelessly communicate with a relay device, an access point, or the like via the antenna 111.

The short-range wireless communication unit 120 is composed of, for example, a radio frequency circuit, a baseband circuit, an integrated circuit and the like. The short-range wireless communication unit 120 transmits and receives a signal via the antenna 121, and performs wireless communication based on BLE with the electronic timepiece 200 which is another wireless communication device.

The satellite radio wave receiving unit 130 is composed of, for example, a radio frequency circuit, a baseband circuit, an integrated circuit, and the like. The satellite radio wave receiving unit 130 receives radio waves from the satellite 40 via the antenna 131.

The RAM 140 includes a volatile memory and is used as a work area for temporarily storing data for the control unit 180 to perform various processes.

The ROM 150 is composed of a non-volatile memory such as a flash memory, and is a program for the control unit 180 to control various functions (for example, a program for realizing information acquisition processing and time adjustment processing described later) and various data ( For example, a regulation area A1, a determination target area A2, and data indicating the information acquired in the information acquisition process, which will be described later, are stored.

The operation unit 160 includes an operation button, a touch panel, and the like, and is an interface used by the user to input an instruction.

The display unit 170 includes, for example, an LCD (Liquid Crystal Display), an EL (Electro Luminescence) display, and the like, and displays an image according to the image data input from the control unit 180.

The control unit 180 is a processor and includes a CPU (Central Processing Unit). The control unit 180 controls various operations of the smartphone 100 by executing various programs stored in the ROM 150.

Here, a functional configuration of the control unit 180 of the smartphone 100 will be described.

The control unit 180 includes a connection control unit 181, an operation time information acquisition unit 182, a position information acquisition unit 183, a map information reception control unit 184, a movement history information acquisition unit 185, a time correction unit 186, a connection type determination unit 187, and a clock unit. 188 and functions as a clock signal generation unit 189.

The connection control unit 181 controls the connection with the electronic timepiece 200. This control includes connection establishment processing and connection disconnection processing.

In the connection establishment process, the connection control unit 181 controls the short-range wireless communication unit 120 based on the scan instruction and receives the advertisement transmitted from the electronic timepiece 200. Upon receiving the advertisement, the connection control unit 181 controls the short-range wireless communication unit 120 and transmits a signal indicating a connection request to the electronic timepiece 200 when the connection is required.

Note that the advertisement is notification information for the electronic timepiece 200 to inform the smartphone 100 of its own existence. The user operation for instructing the scan of the smartphone 100 may be, for example, activation of an application for using the service of the electronic timepiece 200. Further, the scan instruction is not limited to the user operation, and may be periodically performed after the application is started.

In the connection disconnection process, the connection control unit 181 controls the short-range wireless communication unit 120 to transmit a signal indicating a disconnection request to the connected electronic timepiece 200. This processing is executed, for example, when the data communication with the connected electronic timepiece 200 is completed or when the disconnection operation is performed by the user.

The operation time information acquisition unit 182 acquires operation time information indicating the time when the electronic timepiece 200 receives the information acquisition instruction by the proximity operation. Specifically, the operation time information acquisition unit 182 controls the short-range wireless communication unit 120 to receive the acquisition instruction notification transmitted from the electronic timepiece 200. The operation time information acquisition unit 182 acquires the time when the acquisition instruction notification is received as the operation time information.

Strictly speaking, the operation time information is information indicating a time slightly delayed from the time when the electronic timepiece 200 receives the information acquisition instruction by the proximity operation. However, since the time difference between the two is small, they are substantially the same.

The position information acquisition unit 183 acquires position information indicating the user position at the time based on the operation time information acquired by the operation time information acquisition unit 182.

Here, the user position will be described. The smartphone 100 performs short-range wireless communication with the electronic timepiece 200. The electronic timepiece 200 is operated in proximity by the user. Considering such a condition, it can be seen that the smartphone 100, the electronic timepiece 200, and the user have a close positional relationship with each other.

For example, in this positional relationship, even if the mutual distance is about 2 m, the distance is negligible on the map. The position of the smartphone 100 is substantially the same as the position of the user. Therefore, in the present embodiment, the current position of the smartphone 100 is the user position.

There are two acquisition methods of the position information by the position information acquisition unit 183. In the first acquisition method, the location information acquisition unit 183 controls the communication unit 110 to communicate with the NTP pool server 20 and receive the NTP packet from the NTP server 10 allocated by the NTP pool server 20. In this case, the position information acquisition unit 183 acquires the position (latitude and longitude) indicated by the received NTP packet as position information.

In the second acquisition method, the position information acquisition unit 183 controls the satellite radio wave reception unit 130 to receive the radio wave from the satellite 40. In this case, the position information acquisition unit 183 calculates the position (latitude and longitude) based on the received radio wave and acquires the position as position information.

Note that in any of the acquisition methods, the position information acquisition unit 183 acquires the position information promptly after the operation time information acquisition unit 182 receives the acquisition instruction notification transmitted from the electronic timepiece 200. This is to reduce the error in the position information due to the time difference from the time when the electronic timepiece 200 is operated to approach to the time when the position information is acquired.

The map information reception control unit 184 controls the communication unit 110 to receive the map information indicating the position information acquired by the position information acquisition unit 183 from the map information distribution server 60. The map information is information indicating the position information on the map.

By the way, in some countries in the world, for some reasons, the location of important government facilities is not specified due to national defense reasons.In some areas, location information is acquired and displayed on communication terminals, and map information is displayed. Some countries have restrictions on obtaining and displaying them. For example, it may be illegal for a user to know his/her current position by using a radio wave from a satellite, a network, or the like in the vicinity of an important government facility.

In the following description, a country that imposes such a restriction is referred to as a “specific country”. Here, the relationship between the restriction area A1 and the determination target area A2 in the present embodiment will be described with reference to FIG.

In this embodiment, the area to which the address of the specific country is attached, that is, the area within the specific country is defined as the restricted area A1. The restricted area A1 may be only a part of the area where a specific country imposes restrictions. However, in that case, for example, the communication terminal may display the position information and the map information in the restricted area A1 due to the response speed of the communication terminal, the error in the position information, and the like. There is.

Here, the control unit 180 sets the area for determining whether the acquired position information is within the restriction area A1 as the determination target area A2. As shown in FIG. 4, in the present embodiment, the determination target area A2 shown by the broken line is set to a rectangular shape that inscribes the regulation area A1 shown by the solid line. The determination target area A2 is not limited to the rectangular shape and may be an area having a wider area than the regulation area A1. The data indicating the latitude and longitude ranges indicating the determination target area A2 and the information indicating the specific country that is the restriction area A1 are stored in the ROM 150 in advance by, for example, the manufacturer or the seller.

The map information reception control unit 184 receives the map information from the map information distribution server 60 when it is determined that the position information acquired by the control unit 180 is outside the restricted area A1.

The movement history information acquisition unit 185 acquires movement history information based on the plurality of pieces of map information received by the map information reception control unit 184 and stored in the ROM 150. The movement history information is information indicating a movement route in which the positions indicated by a plurality of pieces of map information on a map are connected by a straight line in chronological order.

The time correction unit 186 acquires the UTC time and corrects the time measured by the time counting unit 188 described later. The time adjustment unit 186 also controls the short-range wireless communication unit 120 to transmit the time measured by the time measuring unit 188 to the electronic timepiece 200. As will be described later, the electronic timepiece 200 corrects the time based on this time.

There are two methods of acquiring the UTC time by the time correction unit 186. In the first acquisition method, the time adjustment unit 186 controls the communication unit 110 to communicate with the NTP pool server 20, and receives the NTP packet from the NTP server 10 assigned by the NTP pool server 20. The time information included in this NTP packet is acquired as the UTC time.

In the second acquisition method, the time correction unit 186 controls the satellite radio wave reception unit 130 to receive the radio wave from the satellite 40. The time information generated from the radio wave received from the satellite 40 is acquired as the UTC time.

The time adjustment process performed by the time adjustment unit 186 may be performed regularly (for example, every 30 minutes) or may be performed at a timing based on a user operation.

The connection type determination unit 187 determines what purpose the connection type received from the electronic timepiece 200 indicates. The control unit 180 executes subsequent control processing according to the determination result. For example, if the purpose indicated by the connection type includes time adjustment processing, the time measured by the time measuring unit 188 is transmitted to the electronic timepiece 200. In addition to the time adjustment processing, the purpose indicated by the connection type includes a purpose for searching the smartphone 100 and a purpose for performing various data communications.

The clock unit 188 counts the number of pulses of the clock signal generated by the clock signal generator 189, and measures the time based on the counted number of pulses. Further, the control unit 180 executes various controls at a timing based on the number of pulses counted by the clock unit 188.

The clock signal generation unit 189 generates a clock signal of its own device (smartphone 100). It should be noted that the control unit 180 appropriately controls the frequency of the clock signal of the clock signal generation unit 189 when performing time synchronization according to a received signal from another device.

The configuration of the smartphone 100 according to the present embodiment has been described above. The configuration of the electronic timepiece 200 according to this embodiment will be described below.

As shown in FIG. 3, the electronic timepiece 200 includes a communication device 270 and a display unit 250. The communication device 270 includes a short-range wireless communication unit 210, a RAM 220, a ROM 230, an operation unit 240, and a control unit 260. These components of the communication device 270 and the display unit 250 are connected to each other by a bus line BL.

The short-range wireless communication unit 210 is composed of, for example, an RF circuit, a BB circuit, an LSI and the like. The short-range wireless communication unit 210 performs wireless communication based on BLE with the smartphone 100, which is another wireless communication device, via the antenna 211.

The RAM 220 is composed of a volatile memory, and is used as a work area for temporarily storing data for the control unit 260 to perform various processes.

The ROM 230 is composed of a non-volatile memory such as a flash memory, and stores a program for the control unit 260 to control various functions (for example, a program for performing time adjustment processing and information acquisition processing described later) and various data. ..

The operation unit 240 is an interface that includes operation buttons, a touch panel, and the like, and accepts user operations. The operation unit 240 receives a proximity operation, which is a physical operation such as pressing an operation button or touching a touch panel, instead of a remote operation by an external device.

The display unit 250 is composed of, for example, an LCD, an EL display, or the like, and displays an image according to the image data input from the control unit 260.

The control unit 260 is a processor and includes a CPU. The control unit 260 controls various operations of the electronic timepiece 200 by executing various programs stored in the ROM 230.

Here, the functional configuration of the control unit 260 of the electronic timepiece 200 will be described. The control unit 260 functions as a connection control unit 261, an acquisition instruction notification transmission control unit 262, a time adjustment unit 263, a connection type notification control unit 264, a clock unit 265, and a clock signal generation unit 266.

The connection control unit 261 controls the connection with the smartphone 100. This control includes connection establishment processing and connection disconnection processing.

In the connection establishing process, the connection control unit 261 controls the short-range wireless communication unit 210 to transmit the advertisement to the smartphone 100. The advertisement is transmitted at a regular timing according to the processing of the program, or at a timing when a user operation occurs.

After transmitting the advertisement, the connection control unit 261 receives a signal indicating a connection request from the smartphone 100 via the short-range wireless communication unit 210, and establishes a connection with the smartphone 100. The establishment of this connection enables data communication with the smartphone 100.

In the connection disconnection process, the connection control unit 261 receives a signal requesting disconnection from the smartphone 100 via the short-range wireless communication unit 210, and disconnects the connection with the smartphone 100.

The acquisition instruction notification transmission control unit 262 controls the short-range wireless communication unit 210 to transmit the acquisition instruction notification to the smartphone 100 when the user presses the operation button for executing the information acquisition instruction on the operation unit 240. The information acquisition instruction is an instruction by the user to cause the electronic timepiece 200 to transmit an acquisition instruction notification. The acquisition instruction notification is a notification for causing the smartphone 100 to acquire the operation time information.

In the time adjustment process, the time adjustment unit 263 receives the time transmitted from the smartphone 100 via the short-range wireless communication unit 210. The time correction unit 263 corrects the time measured by the clock unit 265 based on the received time. As a result, the electronic timepiece 200 maintains the state of being time-synchronized with the smartphone 100.

The connection type notification control unit 264 controls the short-range wireless communication unit 210 to notify the smartphone 100 of the connection type.

Here, the connection type is information indicating the purpose of connecting the electronic timepiece 200 to the smartphone 100. The connection type is determined by the content of the user operation of the electronic timepiece 200.

The clock unit 265 counts the number of pulses of the clock signal generated by the clock signal generation unit 266, and measures the time based on the counted number of pulses. Further, the control unit 260 executes various controls at a timing based on the number of pulses counted by the timer unit 265.

The clock signal generation unit 266 generates a clock signal of its own device (electronic timepiece 200). It should be noted that the control unit 260 appropriately controls the frequency of the clock signal of the clock signal generation unit 266 when performing time synchronization according to a received signal from another device.

The configuration of the electronic timepiece 200 according to the present embodiment has been described above. Hereinafter, an example of the information acquisition processing executed by the smartphone 100 and the electronic timepiece 200 will be described with reference to FIG.

This process is executed when the operation button for executing the information acquisition instruction is pressed on the operation unit 240 of the electronic timepiece 200.

When this process is executed, first, a connection establishing process for establishing a connection between the electronic timepiece 200 and the smartphone 100 is executed (steps S201, S101). Specifically, the connection control unit 261 of the electronic timepiece 200 transmits the advertisement to the smartphone 100, and the connection control unit 181 of the smartphone 100 returns a signal indicating a connection request to the electronic timepiece 200. The connection control unit 261 of the electronic timepiece 200 receives the signal indicating the connection request and establishes the connection.

When the connection is established between the electronic timepiece 200 and the smartphone 100, the acquisition instruction notification transmission control unit 262 of the electronic timepiece 200 transmits the acquisition instruction notification to the smartphone 100 (step S202). The operation time information acquisition unit 182 of the smartphone 100 receives the acquisition instruction notification transmitted from the electronic timepiece 200 (step S102). The operation time information acquisition unit 182 of the smartphone 100 acquires the time when the acquisition instruction notification is received as the operation time information.

Here, a connection disconnection process for disconnecting the connection between the electronic timepiece 200 and the smartphone 100 is executed (steps S203 and S103). Specifically, the connection control unit 181 of the smartphone 100 transmits a signal indicating a disconnection request to the connected electronic timepiece 200, and the connection control unit 261 of the electronic timepiece 200 disconnects the connection with the smartphone 100.

The position information acquisition unit 183 of the smartphone 100 acquires the current position of the smartphone 100 as position information indicating the user position (step S104). The position information acquisition unit 183 of the smartphone 100 may acquire the position information from the NTP packet received via the communication unit 110, or the position information is acquired based on the radio wave from the satellite 40 received via the satellite radio wave reception unit 130. Information may be acquired.

Here, the control unit 180 of the smartphone 100 refers to the ROM 150 and determines whether the acquired position information is within the determination target area A2 (step S105).

When the control unit 180 of the smartphone 100 determines that the acquired position information is outside the determination area A2 (step S105; No), steps S106 and S107 described below are skipped and the process proceeds to step S108 described below.

On the other hand, when the control unit 180 of the smartphone 100 determines that the acquired position information is within the determination area A2 (step S105; Yes), the control unit 180 of the smartphone 100 acquires the address of the position information (step S106). ). Specifically, the control unit 180 of the smartphone 100 controls the communication unit 110 to transmit the latitude and longitude of the position information to the map information distribution server 60. The control unit 180 of the smartphone 100 receives the address corresponding to the latitude and longitude of the position information via the communication unit 110.

The control unit 180 of the smartphone 100 determines whether the acquired address is an address outside a specific country (step S107). This determination is made by the control unit 180 of the smartphone 100 referring to the information indicating the specific country stored in the ROM 150.

When the control unit 180 of the smartphone 100 determines that the acquired address is outside the specific country (step S107; Yes), the map information reception control unit 184 of the smartphone 100 sends the map information from the map information distribution server 60 via the communication unit 110. The map information corresponding to the position information is received and the map information is acquired (step S108). In this case, the control unit 180 of the smartphone 100 stores the map information acquired by the map information reception control unit 184 in the ROM 150 in association with the time indicated by the operation time information acquired by the operation time information acquisition unit 182.

On the other hand, when the control unit 180 of the smartphone 100 determines that the acquired address is in the specific country (step S107; No), the control unit 180 of the smartphone 100 uses the operation time information acquired by the operation time information acquisition unit 182. The ROM 150 stores the data indicating that the map information is poorly acquired (step S109). The control unit 180 of the smartphone 100 causes the display unit 170 to display the information stored in the ROM 150 according to a user operation.

Heretofore, an example of the information acquisition process executed by the smartphone 100 and the electronic timepiece 200 has been described. This information acquisition process is executed each time the operation button for executing the information acquisition instruction is pressed on the operation unit 240 of the electronic timepiece 200. Therefore, the map information is accumulated in the ROM 150.

Here, when the user performs an operation for acquiring the movement history information on the operation unit 160 of the smartphone 100, the movement history information acquisition unit 185 of the smartphone 100 displays the plurality of map information stored in the ROM 150. Based on the time indicated by the operation time information, it is read out in time series and transmitted to the map information distribution server 60. The movement history information acquisition unit 185 of the smartphone 100 causes the map information distribution server 60 to generate movement history information and receives the movement history information to acquire the movement history information.

Here, an example of an image displayed as map information on the display unit 170 by the smartphone 100 and an image displayed as movement history information will be described. Here, a case where the acquired map information is the three pieces of map information shown in FIGS. 6A, 6B, and 6C will be described.

FIG. 6A shows the first map information, and shows the point P1 on the map as the position information acquired first. FIG. 6B shows the second map information, and shows the point P2 as the second acquired position information on the map. FIG. 6C shows the third map information, and shows the point P3 on the map as the third acquired position information.
