Description

  The present invention relates to an electronic device that receives a satellite signal transmitted from a position information satellite such as a GPS satellite and acquires time information and position detection.

An electronic timepiece that receives a satellite signal transmitted from a GPS (Global Positioning System) satellite and performs positioning and time adjustment is known (for example, Patent Document 1).
By the way, in an electronic timepiece that receives satellite signals, test modes for performing various operation tests (inspection processing) are set. This test mode is executed at an electronic watch manufacturing factory or after-sales service. Such a test mode (inspection mode) is usually executed by performing a predetermined button operation.

  Here, if the button operation is simplified, the inspection process may be executed by an operation not intended by the user. For this reason, conventionally, the inspection process is executed by performing a complicated button operation.

In the electronic timepiece, tuning circuit parameters in the receiving circuit and values to be referred to in satellite signal reception processing such as time zone setting are stored in a storage device, and the type of electronic timepiece and the time zone setting value are stored. When the value is changed, the value of the storage device needs to be rewritten.
Therefore, in the electronic watch, when rewriting the value, the service center removes the back cover to expose the inside of the case, and accesses the circuit board disposed inside the case to change the value of the storage device. It was.

JP 2011-237314 A

  However, since the button operation for executing the inspection process is complicated, there is a problem that the operation when executing the inspection process in the inspection process becomes complicated and the work efficiency of the inspection is lowered.

  In addition, when changing the value of the storage device, it is necessary to remove the back cover, so that the rewriting work becomes complicated and the work efficiency is lowered.

One object of the present invention is to provide an electronic apparatus capable of improving the work efficiency when executing an inspection process.
Another object of the present invention is to provide an electronic apparatus capable of improving the work efficiency during the value rewriting work.

  The electronic device of the present invention includes a reception unit that receives a satellite signal transmitted from a position information satellite, a position information calculation unit that obtains latitude, longitude, and altitude from the satellite signal received by the reception unit, and the latitude, longitude, An inspection process execution unit that executes an inspection process set in advance when at least one value of the altitude corresponds to a preset condition.

According to the present invention, the inspection processing execution unit executes the inspection processing when at least one value of latitude, longitude, and altitude calculated by the position information calculation unit satisfies the setting condition. For this reason, it is not necessary for the inspector to perform the inspection process with a button operation, and it is only necessary to set the simulation signal generated by the GPS simulator or the like according to the inspection process to be performed and perform the reception operation. Easy to implement. For this reason, it is possible to improve work efficiency when inspecting an electronic device such as a satellite signal receiving device or an electronic timepiece that receives the satellite signal.
In addition, since the inspection process is not executed by a button operation, it is possible to reliably prevent the inspection process from being erroneously executed by a button operation not intended by the user.

Here, it is preferable that the inspection process execution unit selects and executes the type of the inspection process according to the altitude value when the altitude value satisfies the condition.
In this case, the value of the altitude can be set to be smaller than, for example, an altitude of about −400 m of the Dead Sea, which is the lowest altitude area on the ground where satellite signals can be received. In this case, since the high value is not received in the normal reception process, it is possible to prevent the inspection process from being erroneously executed. Further, since the altitude value can be easily changed in units of 50 m or 100 m, the type of inspection process can be easily selected and executed according to the altitude value.

The inspection processing execution unit selects the type of the inspection processing according to at least one value of the latitude or the longitude when at least one value of the latitude or the longitude satisfies the condition. It may be executed.
In this case, if the latitude and longitude values are set to a place where a normal user hardly moves, such as the North Pole or the South Pole, or the Pacific Ocean or the Atlantic Ocean, for example, the latitude can be obtained by normal reception processing. And never receive longitude values. For this reason, it can prevent that a test | inspection process is performed accidentally. Furthermore, since a plurality of points can be set according to the values of latitude and longitude, the type of inspection process can be easily selected and executed according to the values of latitude and longitude.

  The electronic device according to the present invention includes a receiving unit that receives a satellite signal transmitted from a position information satellite, a position information calculating unit that obtains at least latitude and longitude from the satellite signal received by the receiving unit, and the previous reception process. The distance between the point specified by the latitude and longitude obtained by the position information calculation unit and the point specified by the latitude and longitude obtained by the position information calculation unit during the current reception processing corresponds to a preset condition. And an inspection process execution unit that executes a preset inspection process when an elapsed time from the previous reception process to the current reception process is satisfied. .

According to the present invention, the inspection process execution unit executes the inspection process when the elapsed time and the movement distance obtained by the two reception processes satisfy the set condition. For this reason, it is not necessary for the inspector to perform the inspection process with a button operation, and the simulation signal generated by the GPS simulator or the like can be received at different locations (positions corresponding to the moving distance condition) during the two reception processes. ) Is calculated, and only the receiving operation in the positioning process is performed, so that the inspection process can be easily executed. For this reason, the work efficiency in an inspection process can be improved.
In addition, since the inspection process is not executed by a button operation, it is possible to reliably prevent the inspection process from being erroneously executed by a button operation not intended by the user.
In this case, the value of the distance can be set to a distance that cannot be moved even by an airplane within the elapsed time. In this case, since the distance does not become the value in the normal two reception processes, it is possible to further prevent the inspection process from being erroneously executed.
In addition, when having a reception process that does not calculate position information (for example, a time reception process that acquires time information from a satellite signal), the “previous and current reception processes” are not time measurement reception processes, These are a reception process in which the previous position information is calculated and a reception process in which the current position information is calculated.

Here, it is preferable that the inspection processing execution unit selects and executes the type of the inspection processing according to the distance.
Since the distance value can be easily changed by setting a simulation signal, the type of inspection mode can be easily selected and executed according to the distance value.

  The electronic device of the present invention includes a reception unit that receives a satellite signal transmitted from a position information satellite, a position information calculation unit that obtains latitude, longitude, and altitude from the satellite signal received by the reception unit, and the latitude, longitude, A rewriting process executing unit configured to execute a rewriting process set in advance when at least one value of the altitude corresponds to a preset condition;

According to the present invention, for example, the rewrite processing execution unit can select a rewrite process based on the altitude of the position information calculated by the position information calculation unit, and can set a data rewrite target and rewrite data based on the latitude and longitude. For this reason, when various data is rewritten after the manufacture and sale of the electronic device, it is not necessary to collect the electronic device at the service center, open the back cover and access the circuit board as in the conventional case, and it is simulated by the GPS simulator. Since it is only necessary to generate a signal and perform reception processing by the electronic device, the rewriting process can be easily performed. For this reason, the rewriting work can be easily performed not only at the service center but also at the store of the watch store, and the work efficiency can be improved.
Further, since it is not necessary to open and close the back cover, it is possible to prevent the waterproofness of the electronic device from being lowered.

Here, when the altitude value meets the condition, the rewrite processing execution unit selects the type of the rewrite processing according to the altitude value, and according to one of the latitude and longitude values. It is preferable that the rewriting target is selected and the rewriting target value is rewritten with a value set according to the other value of the latitude or longitude.
In this case, when rewriting the time zone or daylight saving time setting values, the area to be rewritten can be selected with the latitude value, and the setting value can be rewritten with the longitude value. It can be easily rewritten only by receiving three advanced data. Therefore, the efficiency of rewriting work can be improved.

The receiving unit further includes a storage unit storing at least one of a setting value for a tuning circuit, a parameter for a motor, a time zone setting value, and a daylight saving time setting value, and the rewrite target is stored in the storage unit The set value is preferably set.
In this case, various setting values for reception and motor stored in the storage unit can be easily rewritten.

In addition, it is preferable that an operation unit for instructing reception processing is provided, and the reception unit performs reception processing when an operation for instructing reception processing is performed by the operation unit.
Execution of the inspection process and execution of the data rewriting process need only be performed by the reception process by operating the operation unit, so that the work efficiency of the inspector can be improved. Further, this receiving operation is the same as the actual receiving operation, and it is not necessary to perform a special operation, so that workability can be improved in this respect.

When the electronic device according to the present invention has succeeded in obtaining the time information by the time measuring unit for measuring the time, the time display unit for displaying the time, and the reception process of the receiving unit, the time measuring unit uses the time information. And a time correction unit that corrects the time being measured.
According to the present invention, the inspection process and the data rewrite process can be executed only by performing the reception process, so that the work efficiency of the inspector can be improved.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram showing an electronic timepiece 1 (electronic device) and a GPS simulator 800 according to the first embodiment of the present invention, and FIG. 2 is a schematic sectional view of the electronic timepiece 1.
As shown in FIG. 1, the electronic timepiece 1 acquires time information by receiving satellite signals from at least one GPS satellite 100 out of a plurality of GPS satellites 100 orbiting the earth over a predetermined orbit. In addition, it is configured to receive satellite signals from at least three GPS satellites 100 and acquire position information. The GPS satellite 100 is an example of the position information satellite in the present invention, and a plurality of GPS satellites 100 exist above the earth. Currently, about 30 GPS satellites 100 orbit.

[Electronic clock]
As is clear from FIG. 1, the electronic timepiece 1 is a wristwatch that is worn on the wrist of a user, and includes a dial 11 and hands 12 (time display unit), and measures and displays the time.
Most of the dial plate 11 is formed of a non-metallic material (for example, plastic or glass) that easily transmits light and microwaves in the 1.5 GHz band.
The pointer 12 is provided on the surface side of the dial 11. The pointer 12 includes a second hand 121, a minute hand 122, and an hour hand 123 that rotate about the rotary shaft 13, and is driven by a step motor through a gear.

[Operation section operation]
In the electronic timepiece 1, processing according to manual operation of the operation unit 70 having the crown 14 and the buttons 15 and 16 is executed. Specifically, when the crown 14 is operated, a manual correction process for correcting the display time according to the operation is performed. When the button 15 is pressed for a long time (for example, 3 seconds or more), a manual reception process (forced reception process) for receiving satellite signals is executed.
Further, when the button 16 is pressed, a switching process for switching the reception mode (time measurement mode or positioning mode) is executed. Here, the time measurement mode is a mode for acquiring time information from a satellite signal. The positioning mode is a mode in which position information is acquired by performing positioning calculation based on a satellite signal, and time information is acquired from the satellite signal. In the positioning mode, the time information does not have to be acquired from the satellite signal. The setting of the reception mode by operating this button 16 is stored in the storage device 60 described later. At this time, when the positioning mode is set, the second hand 121 moves to the “Fix” position (10-second position), and when the positioning mode is set, the second hand 121 is moved to the “Time” position ( Move to the 5 second position). For this reason, the user can easily confirm the set reception mode.
Note that the reception mode may be fixed to the timekeeping mode or the positioning mode regardless of the mode set by the button 16 during the regular reception process described later, or the reception mode set by the button 16 during the regular reception process. You may control by. In this embodiment, as described later, the timed reception process is fixed to the timekeeping mode.

When the button 15 is pressed for a short time (for example, less than 3 seconds), a result display process for displaying the result of the previous reception process is performed. That is, when the reception is successful in the positioning mode, the second hand 121 moves to the position “Fix” (10-second position), and when the reception is successful in the time-measurement mode, the second hand 121 is “Time” (the 5-second position). ) Position. In the case of reception failure, the second hand 121 moves to the “N” position (20-second position).
Note that these instructions by the second hand 121 are also performed during reception. During reception in the positioning mode, the second hand 121 moves to the “Fix” position (10-second position), and during reception in the time-measurement mode, the second hand 121 moves to the “Time” position (5-second position). When the GPS satellite cannot be captured, the second hand 121 moves to the “N” position (20-second position).

[Structure of electronic watch]
As shown in FIG. 2, the electronic timepiece 1 includes an outer case 17 made of a metal such as stainless steel (SUS) or titanium. The exterior case 17 is formed in a substantially cylindrical shape. A surface glass 19 is attached to the opening on the surface side of the outer case 17 via a bezel 18. The bezel 18 is made of a non-metallic material such as ceramics in order to improve satellite signal reception performance. A back cover 20 is attached to the opening on the back side of the exterior case 17. In the exterior case 17, a movement 21, a solar cell 22, a GPS antenna 23, a secondary battery 24, and the like are arranged.

  The movement 21 includes a driving mechanism 210 including a step motor for driving the hands 12 and a wheel train 211. The step motor is composed of a motor coil 212, a stator, a rotor, and the like, and drives the pointer 12 via the train wheel 211 and the rotating shaft 13.

A circuit board 25 is disposed on the rear cover 20 side of the movement 21.
The circuit board 25 is provided with a receiving circuit 30 for processing a satellite signal received by the GPS antenna 23, a control device 40 for performing various controls such as driving control of the receiving circuit 30 and a step motor. The receiving circuit 30 and the control device 40 are driven by power supplied from the secondary battery 24.

[Solar cell]
The solar cell 22 is a photovoltaic element that performs photovoltaic generation to convert light energy into electrical energy. The solar cell 22 includes an electrode for outputting generated power, and is disposed on the back side of the dial 11. Since most of the dial plate 11 is made of a material that easily transmits light, the solar cell 22 can receive light transmitted through the surface glass 19 and the dial plate 11 and perform photovoltaic power generation.

The solar cell 22 is supported by a solar panel support substrate 220. The solar panel support substrate 220 is a conductive substrate having a thickness dimension of, for example, 0.1 mm formed of a metal material such as BS (brass), SUS (stainless steel), or titanium alloy. As a result, the solar panel support substrate 220 functions as a part of the GPS antenna 23 with the same current distribution as that of the GPS antenna 23 arranged close to the solar panel support substrate 220.
The solar panel support substrate 220 is incorporated so as not to contact the outer case 17. That is, the solar panel support substrate 220 is arranged without the outer peripheral edge being separated from and contacting the inner peripheral surface of the exterior case 17.

The solar cell 22 is electrically connected to the circuit board 25 via the conductive coil spring 22A, and the current generated by the solar cell 22 is stored in the secondary battery 24 via the conductive coil spring 22A.
The dial plate 11 and the solar cell 22 are formed so that the outer peripheral diameters of the dial plate 11 and the inner peripheral diameter of the dial ring 140 are concealed by the dial ring 140, so that the solar panel support substrate 220 is visually recognized from the outside. It will never be done. Further, the outer dimensions of the solar panel support substrate 220 are larger than those of the solar cell 22 and the dial plate 11 and are expanded to the position of the lower surface of the GPS antenna 23.

[GPS antenna]
The GPS antenna 23 is a ring antenna including a ring-shaped dielectric base material 231 having a rectangular cross-sectional shape and having an antenna electrode 232 formed on the surface thereof.
The dielectric base material 231 shortens the wavelength of radio waves. For example, so-called micalex (εr = 6), which is ceramics mainly composed of alumina (εr = 8.5) or ceramics composed of mica, for example. 0.5 to 9.5), glass (εr = 5.4 to 9.9), diamond (εr = 5.68), and the like.

  The antenna electrode 232 is formed by printing a conductive metal element such as copper or silver on the surface of the dielectric substrate 231, or attaching a conductive metal plate such as silver or copper to the surface of the dielectric substrate 231. Are formed integrally with the dielectric base material 231 in a linear manner. The antenna electrode 232 may be formed by patterning the surface of the dielectric substrate 231 by electroless plating.

The connection pin 31 is in contact with the antenna electrode 232. The connection pin 31 is inserted into a substantially cylindrical connection base 32. The connection base 32 is connected to a printed wiring on the circuit board 25 and is erected.
The connection pin 31 and the connection base 32 are electrically connected to the receiving circuit 30 through printed wiring. The connection base 32 is provided with a biasing member such as a coil spring inside the cylinder, and biases the connection pin 31 inserted into the connection base 32 toward the antenna electrode 232 side. Thereby, the connection pin 31 is pressed against the feeding point of the antenna electrode 232, and the connection state between the connection pin 31 and the antenna electrode 232 is maintained even when, for example, an impact is applied to the electronic timepiece 1.

In this embodiment, the back cover 20 made of a conductive member also serves as a ground plate (reflecting plate) of the GPS antenna 23. The back cover 20 is electrically connected to a ground terminal 26 provided on the movement 21. The ground terminal 26 is connected to the ground potential of the receiving circuit 30 of the movement 21. For this reason, the back cover 20 is electrically connected to the ground potential of the receiving circuit 30 via the ground terminal 26, and a ground plate (reflective) that reflects radio waves incident from the surface glass 19 side toward the GPS antenna 23. Plate). Since the exterior case 17 of the conductive member that is in contact with the back cover 20 also has a ground potential, the exterior case 17 also functions as a ground plate.
Furthermore, since the back cover 20 and the outer case 17 are made of metal, in addition to functioning as a ground plate, the influence on the GPS antenna 23 when mounted on the user's arm can be avoided. That is, if the case is a plastic case, the resonance frequency of the GPS antenna 23 varies depending on the influence of the arm in the vicinity and when it is not worn, which is not preferable because of a performance difference. However, since the case is made of metal, the effect of the arm can be avoided by the shielding effect, and in this embodiment, there is almost no difference in antenna characteristics between when the sensor is mounted and when it is not mounted, and stable reception performance can be obtained. However, a plastic case can be used to increase the receiving sensitivity.

[Secondary battery]
The secondary battery 24 is a power source for the electronic timepiece 1 and accumulates electric power generated in the solar cell 22.
In the electronic timepiece 1, the two electrodes of the solar cell 22 and the two electrodes of the secondary battery 24 can be electrically connected to each other by two conductive coil springs 22A. The secondary battery 24 is charged by the photovoltaic power generation. In the present embodiment, a lithium ion battery suitable for a portable device is used as the secondary battery 24. However, a lithium polymer battery or other secondary battery may be used, or a power storage different from the secondary battery. A body (for example, a capacitor) may be used.

[Circuit configuration of satellite signal receiver]
FIG. 3 is a block diagram showing the circuit configuration of the satellite signal receiving device 10 and the configuration of the GPS simulator 800 in the electronic timepiece 1. As shown in this figure, the satellite signal receiving device 10 includes a receiving circuit 30 (receiving unit), a control device 40 (control unit), a time measuring device 50 (time measuring unit), a storage device 60 (storage unit), And an operation unit 70.

[Configuration of storage device]
As illustrated in FIG. 4, the storage device 60 includes a time data storage unit 600, an inspection mode setting storage unit 670, a time zone data storage unit 680, and a scheduled reception time storage unit 690.

  The time data storage unit 600 stores reception time data 610, leap second update data 620, internal time data 630, clock display time data 640, and time zone data 650.

  The reception time data 610 stores time information (GPS time) acquired from the satellite signal. The reception time data 610 is normally updated with a reference signal used for timing the time by the timing device 50, and is corrected by the acquired time information (GPS time) when a satellite signal is received.

  The leap second update data 620 stores at least current leap second data. That is, in subframe 4 and page 18 of the satellite signal, “current leap second”, “leap second update week”, “leap second update date”, and “leap second after update” are included as data relating to leap seconds. Each data is included. Among these, in the present embodiment, at least “current leap second” data is stored in the leap second update data 620.

  The internal time data 630 stores internal time information. This internal time information is updated by the GPS time stored in the reception time data 610 and the “current leap second” stored in the leap second update data 620. That is, UTC (Coordinated Universal Time) is stored in the internal time data 630. When the reception time data 610 is updated with the reference signal, the internal time information is also updated.

  The clock display time data 640 stores time data obtained by adding the time zone data of the time zone data 650 to the internal time information of the internal time data 630. The time zone data 650 is set by position information obtained when received in the positioning mode.

The time zone data storage unit 680 stores position information (latitude, longitude) and time zone (time difference information) in association with each other. For this reason, when position information is acquired in positioning mode, time zone data can be acquired based on the position information (latitude, longitude).
For example, since the standard time in Japan is the time (UTC + 9) advanced by 9 hours with respect to UTC, when the position information acquired in the side mode is Japan, the control device 40 reads from the time zone data storage unit 680. Read time difference information (+9 hours) in Japan Standard Time and store it in the time zone data 650.

  The time zone data storage unit 680 may further store a city name and time zone data in association with each other. In this case, when the user selects a city name for which the user wants to know the local time by operating the operation unit 70, the control device 40 searches the time zone data storage unit 680 for the city name set by the user, Time zone data corresponding to the city name may be acquired and set in the time zone data 650.

  The scheduled reception time storage unit 690 stores the scheduled reception time for executing the scheduled reception process by the scheduled reception control unit 410.

  In the inspection mode setting storage unit 670, conditions for executing an inspection mode (inspection process) shown in Table 1 described later are set and stored.

[Receiver circuit]
The receiving circuit 30 is a load driven by the electric power stored in the secondary battery 24, and when driven by the control device 40, receives a satellite signal transmitted from the GPS satellite 100 through the GPS antenna 23. The reception circuit 30 transmits information such as the acquired orbit information and GPS time information to the control device 40 when the satellite signal is successfully received. On the other hand, when the reception of the satellite signal fails, the receiving circuit 30 transmits information to that effect to the control device 40. Note that the configuration of the receiving circuit 30 is the same as the configuration of a known GPS receiving circuit, and thus description thereof is omitted.

[Control device]
The control device 40 is composed of a CPU that controls the electronic timepiece 1. The control device 40 includes a scheduled reception control unit 410, a manual measurement reception control unit 420, and a manual positioning reception control unit 430 as reception control units that control the reception circuit 30 and execute reception processing. In addition, the control device 40 includes a position information calculation unit 440, a time correction unit 450, and an inspection mode execution unit 460 (inspection processing execution unit).

[Regular reception control unit]
The scheduled reception control unit 410, when the time measured by the timing device 50, specifically, the internal time data 630 becomes the scheduled reception time stored in the scheduled reception time storage unit 690 of the storage device 60, The reception circuit 30 is operated to perform reception processing in the time measurement mode.

[Manual timing reception control unit]
The manual timekeeping reception control unit 420 receives the reception circuit when the user intentionally presses the button 15 of the operation unit 70 for several seconds (for example, 3 seconds) or more while the reception mode is set to the timekeeping mode. 30 is operated to perform reception processing (manual reception processing, forced reception processing) in the timekeeping mode.
The reception mode can be selected by pressing the button 16 as described above. That is, every time the button 16 is pressed, the reception mode is switched between the time measurement mode and the positioning mode.

[Manual positioning reception control unit]
When the reception mode is set to the positioning mode, the manual positioning reception control unit 430 activates the receiving circuit 30 when the user intentionally presses the button 15 of the operation unit 70 for several seconds (for example, 3 seconds) or more. It operates to perform reception processing (manual reception processing, forced reception processing) in the positioning mode.

[Location information calculation unit]
The position information calculation unit 440 calculates and obtains latitude, longitude, altitude, that is, positioning information, based on the satellite signal received by the receiving circuit 30. Note that the altitude calculated by the position information calculation unit 440 is usually calculated by using the height from an ellipsoid that approximates the shape of the earth, but is not limited to this, the altitude that is the height from the sea surface, The sea level may be calculated and used.

[Time correction section]
The time correction unit 450 acquires time information from the received satellite signal, corrects the reception time data 610 timed by the time measuring device 50 based on the acquired time information, and further corrects the internal time by correcting the leap second update data 620. The data 630 is corrected.

[Inspection mode execution section]
The inspection mode execution unit 460 executes various inspection processes (inspection modes) in the electronic timepiece 1.
The inspection mode execution unit 460 of the present embodiment is executed by selecting the inspection mode based on the altitude value calculated by the position information calculation unit 440 based on the received satellite signal. A specific example of the inspection mode for the altitude value is shown in Table 1.

[Time measuring device]
The timing device 50 includes a movement 21 and is driven by the electric power stored in the secondary battery 24 to perform timing processing. In the time measurement process, the time is measured, and a time (display time) corresponding to the time is indicated by the pointer 12.

[GPS simulator]
The GPS simulator 800 includes a simulation signal setting unit 810 and a simulation signal generation unit 820, and is a device that outputs a GPS signal simulation signal from the antenna 850.
The simulated signal setting unit 810 sets each parameter set in the GPS signal such as latitude, longitude, altitude, date and time, the number of satellites, and signal strength. The specific setting values of each parameter may be input by operating buttons provided on the GPS simulator 800, or by connecting a personal computer or the like to the GPS simulator 800 and transmitting the setting values from the personal computer. Good.

The simulated signal generator 820 generates a simulated GPS signal (simulated signal) based on the parameters set by the simulated signal setting unit 810. That is, when the simulation signal generated by the simulation signal generator 820 is received by the satellite signal receiver 10 of the electronic timepiece 1 and the position information is calculated by the position information calculator 440, the calculated position information is the simulated signal. The trajectory information of the simulation signal is set so as to be the parameter set by the setting unit 810.
The simulation signal generator 820 outputs the simulation signal via the antenna 850.

[Operation of control device]
FIG. 5 is a flowchart showing the manual reception process SA10 in the satellite signal receiving apparatus 10 according to the first embodiment.
First, the control device 40 determines whether or not there is a manual reception operation in the positioning mode by the operation unit 70 (SA11). When it is determined No at SA11, the determination process at SA11 is repeated.

When it determines with Yes by SA11, the control apparatus 40 operates the manual positioning reception control part 430, and starts the reception process in positioning mode (SA12).
After the reception process at SA12 is started, the control device 40 determines whether the satellite signal has been successfully received (SA13).

When it is determined No in SA13 (when reception fails), the control device 40 ends the manual reception process without correcting the internal time and time zone.
On the other hand, when it is determined that the satellite signal has been successfully received (SA13: Yes), the control device 40 operates the position information calculation unit 440 to calculate position information based on the acquired satellite signal ( SA14).

After calculating the position information, the control device 40 determines whether the altitude in the calculated position information is less than −500 m (SA15). When it is determined No in SA15, the control device 40 corrects the internal time based on the acquired time information, and corrects the time zone data 650 based on the position information using the time correction unit 450 (SA16).
When the internal time data 630 and the time zone data 650 are corrected, the time data for clock display 640 is also corrected, and the instruction of the hands 12 is also corrected in conjunction with it.

On the other hand, when it is determined Yes in SA15, the control device 40 determines the type of the inspection mode and executes the inspection (SA17).
The inspection mode is executed when the altitude is less than −500 m for the following reason. That is, the lowest altitude at the point where the satellite signal of the GPS satellite 100 can be received is the “dead sea” area where the altitude is about −400 m. Accordingly, since there is no actual point that is less than −500 m, when the position information is calculated based on the received satellite signal and the altitude is less than −500 m, the simulated signal generated by the GPS simulator 800 is generated. Can be determined to be received.

  Therefore, the inspection mode execution unit 460 executes the inspection according to the acquired altitude as shown in Table 1 above. For this reason, the simulation signal setting unit 810 of the GPS simulator 800 sets the altitude value of the simulation signal according to the type of inspection mode to be executed, and transmits the simulation signal generated by the simulation signal generation unit 820 from the antenna 850. Then, the satellite signal receiving device 10 receives the signal. Thereby, the inspection mode execution unit 460 of the control device 40 in the satellite signal receiving apparatus 10 executes an inspection mode based on the altitude of the position information calculated from the received satellite signal.

[Driving inspection mode]
The inspection mode execution unit 460 executes the operation inspection mode of the electronic timepiece 1 when the altitude is less than −500 m and −599 m or more. In the operation inspection mode, the electronic timepiece 1 is operated for several hours to several tens of hours in a high temperature atmosphere of about 60 ° C. and a low temperature atmosphere of about −10 ° C., for example. The quality check (good / bad determination) in the operation inspection is performed by the inspector confirming that the time display is stopped or delayed by the motor of the electronic timepiece 1 or confirming the voltage of the secondary battery 24 after the test.

[Solar cell inspection mode]
The inspection mode execution unit 460 executes the solar cell inspection mode when the altitude is less than −600 m and −699 m or more. In the solar cell inspection mode, it is confirmed whether the solar cell 22 generates power under illumination and the secondary battery 24 is normally charged. For example, when the secondary battery 24 is charged, the inspection mode execution unit 460 indicates the Yes position (for example, the 10-second position) of the dial 11 with the second hand 121. Point to the 20 second position) and indicate the test result. The inspector determines the quality of the solar cell 22 based on the instruction result of the second hand 121.

[Sensitivity inspection mode]
The inspection mode execution unit 460 executes the sensitivity inspection mode when the altitude is less than −700 m and −799 m or more. In the sensitivity inspection mode, a simulation signal having a value determined by the GPS simulator 800 is transmitted, and the inspection mode execution unit 460 displays the received value with the second hand 121. The inspector determines whether the sensitivity test is good or not by checking whether the value displayed by the second hand 121 is the predetermined value.

[Percentage inspection mode]
The inspection mode execution unit 460 executes the rate inspection mode when the altitude is less than −800 m and −899 m or more. The rate check mode is for checking whether the accuracy of the electronic timepiece 1 is within ± 10 seconds per month. The inspection mode execution unit 460 moves only the motor of the second hand 121 every second, and measures the electromagnetic pulse of the motor with a measuring machine. The inspector confirms the accuracy of 1 second by measuring the interval between the electromagnetic pulses measured by the measuring machine.

[Device inspection mode]
The inspection mode execution unit 460 executes the device inspection mode when the altitude is less than −900 m and −999 m or more. In the device inspection mode, the inspection mode execution unit 460 checks whether a normal value is written in the storage device 60. For example, if a normal value is written, the inspection mode execution unit 460 indicates a Yes position (for example, a 10-second position) of the dial 11 with the second hand 121, and if a normal value is not written, No. The inspection result is indicated by pointing to the position (for example, the position of 20 seconds).

  When executing the inspection mode and displaying the inspection result, the control device 40 ends the inspection mode after a predetermined time (for example, about 1 to 2 minutes) (SA18). And the control apparatus 40 complete | finishes manual reception process SA10, and returns to the timepiece mode which performs a normal time display. In addition, when the inspector performs a predetermined button operation while the inspection result is displayed, the time mode may be returned.

The simulation signal generator 820 of the GPS simulator 800 generates a simulation signal in which the calculated position information has an altitude of −550 m when the driving inspection mode is executed, and when the solar cell inspection mode is executed, the altitude is When generating a simulated signal of −650 m and executing the sensitivity inspection mode, generating the simulated signal of −750 m at the altitude, and generating the simulated signal of −850 m at the altitude when executing the rate test mode, When the inspection mode is executed, a simulation signal having the altitude of −950 m is generated.
Further, as described above, when the GPS simulator 800 receives the simulation signal by the satellite signal receiving device 10 and calculates the position information by the position information calculation unit 440, the altitude, the latitude, the longitude, and the like are set. In addition, simulation signals are generated by simulating orbit information of four satellite signals. For this reason, when the position information calculation unit 440 receives the simulation signal and calculates the position information, an error of about 10 m may occur with respect to the altitude.
In consideration of this error, the inspection mode execution unit 460 sets and determines a range of about 100 m as a condition for determining the inspection mode as described above. Therefore, the inspection mode execution unit 460 can correctly determine the inspection mode corresponding to the altitude set by the GPS simulator 800, and can reliably execute the set inspection mode.

[Effects of First Embodiment]
According to such 1st Embodiment, the following effects are obtained.
(1) The inspection mode execution unit 460 executes the inspection mode when the altitude of the position information calculated by the position information calculation unit 440 is a specific value. For this reason, it is not necessary for the inspector to execute the inspection mode by operating the button, and the simulation signal generated by the GPS simulator 800 is set according to the inspection mode to be executed, and the operation unit 70 performs the receiving operation in the positioning mode. Therefore, the inspection process can be easily performed. For this reason, the work efficiency in the inspection process in the production line of the factory can be improved.
Further, since the inspection mode is not executed by a button operation, it is possible to reliably prevent the inspection mode from being erroneously executed by a button operation not intended by the user.

(2) The specific altitude for instructing the execution of the inspection mode cannot be actually received. Since the specific altitude is set to less than -500 m, the inspection mode is set when the satellite signal of the GPS satellite 100 is actually received outdoors. Never executed. That is, the inspection mode can be executed only when a simulated signal from the GPS simulator 800 is received.

(3) Since various inspection modes are selected and executed according to the altitude value, the inspector can execute various inspection modes only by performing a receiving operation in the positioning mode. In this respect as well, the work efficiency of the inspection process can be improved.

[Second Embodiment]
Next, 2nd Embodiment of this invention is described based on drawing. In addition, since it is the same as that of the said 1st Embodiment except manual reception processing, the description is abbreviate | omitted.

FIG. 6 is a flowchart illustrating the manual reception process SB10 in the control device 40 according to the second embodiment.
As shown in FIG. 6, the control device 40 performs the processes of SB11 to SB18. Here, the processing of SB11 to SB14, SB16, and SB18 is the same processing as SA11 to SA14, SA16, and SA18 in the first embodiment, and thus the description thereof is omitted.

In the first embodiment, in SA15, it is determined whether to execute the inspection mode based on the calculated altitude value of the position information.
On the other hand, the second embodiment is different in that the control device 40 specifies and executes the inspection mode not by altitude but by latitude or longitude in the calculated position information.
That is, when it is determined Yes in SB13, the control device 40 determines whether the latitude or longitude in the position information calculated by the position information calculation unit 440 satisfies a preset condition for the inspection mode (SB15). ).

  When it is determined No in SB15, the control device 40 corrects the internal time based on the acquired time information and the time zone data 650 based on the position information by the time correction unit 450, as in the first embodiment (SB16). ). When the internal time data 630 and the time zone data 650 are corrected, the time data for clock display 640 is also corrected, and the instruction of the hands 12 is also corrected in conjunction with it.

On the other hand, when it is determined Yes in SB15, the control device 40 determines the type of the inspection mode and executes the inspection (SB17).
Here, the latitude and longitude for the inspection mode are locations on the earth that actually exist, but places where general users are unlikely to be at that location (for example, near the North Pole or the South Pole, , Pacific and Atlantic offshore). Thereby, when the latitude and longitude of the position information are acquired, it is possible to determine whether the reception in the normal positioning mode is performed or whether the execution of the inspection mode by the GPS simulator 800 is instructed.

[Judgment and execution of inspection mode]
A specific determination and execution method in SB 17 will be described with reference to Table 2.
The inspection mode execution unit 460 of the control device 40 corresponds to the inspection mode when the latitude and longitude of the position information calculated in SB14 satisfy any of the conditions in Table 2 stored in the inspection mode setting storage unit 670. Execute. Each inspection mode in Table 2 performs processing for displaying information related to reception recorded in the storage device 60 of the electronic timepiece 1.

[Automatic reception history display mode]
As shown in Table 2, the inspection mode execution unit 460 determines that the calculated latitude and longitude are within the range of 89.9 to 90.0 degrees north latitude and 0 to 0.1 degrees east longitude, that is, the position near the north pole. If it is information, an inspection mode for displaying a record of automatic reception history is executed. In addition, since it can be determined only by the latitude whether it is the vicinity of the North Pole, the inspection mode may be determined only by the latitude.
Here, the automatic reception history is as follows. The satellite signal receiving device 10 receives the light having a predetermined illuminance or more by receiving the scheduled reception that automatically starts reception at a predetermined time, or when the power generation voltage of the solar cell 22 exceeds the threshold, that is, the electronic timepiece 1. Automatic reception processing such as automatic optical reception that automatically starts reception when it is detected that the camera is placed outdoors can be performed. Then, the satellite signal receiving device 10 records the time when the automatic reception is started and the reception result in the storage device 60.
When the inspection mode execution unit 460 executes the inspection mode for displaying the record of the automatic reception history, the inspection mode execution unit 460 displays the automatic reception start time and the reception result history recorded in the storage device 60.
For example, the inspection mode execution unit 460 displays the latest reception result (success or failure of reception) with the second hand 121 and displays the reception start time with the hour hand 123 and the minute hand 122. To display the previous reception history, one of the buttons 15 and 16 is pressed. In order to display a reception history after the currently displayed history, the other of the buttons 15 and 16 is pressed.
In addition, if it is the electronic timepiece 1 provided with the digital display part, a several reception log | history can be displayed at once. Furthermore, when an audio output unit such as a speaker or headphones is provided, the reception history may be output by audio.

[Reception success rate display mode]
If the calculated latitude and longitude are within the range of 89.9 to 90.0 degrees south latitude and 0 to 0.1 degrees west longitude, that is, if the position information is near the south pole, Execute the inspection mode that displays the record of the success rate of reception. In addition, since it can be determined only by the latitude whether it is in the vicinity of the South Pole, the inspection mode may be determined only by the latitude.
Here, the reception success rate is a value obtained by dividing the number of successes by the number of receptions. When the inspection mode execution unit 460 executes the inspection mode for displaying the record of the reception success rate, the inspection mode execution unit 460 calculates the reception success rate based on the number of successes and the number of receptions stored in the storage device 60, and calculates the success rate numerical value. They are displayed on the pointer 12 or the digital display unit, or output by the audio output unit.

[Reception level display mode]
The inspection mode execution unit 460 is position information on the Pacific Ocean near the equator when the calculated latitude and longitude are within the range of 0.0 to 0.1 degrees north latitude and 173.0 to 173.1 degrees west longitude. In the case, the inspection mode for displaying the record of the reception level is executed.
Here, the reception level is the signal strength of the GPS satellite 100 recorded for each reception process. When executing the inspection mode for displaying the reception level, the inspection mode execution unit 460 displays the value of the signal intensity stored in the storage device 60 on the pointer 12 or the digital display unit, or outputs it on the audio output unit.

[Leap second display mode]
The inspection mode execution unit 460 is position information on the Atlantic Ocean near the equator when the calculated latitude and longitude are within the range of 0.0 to 0.1 degrees south latitude and 25.0 to 25.1 degrees west longitude. In some cases, an inspection mode is displayed that displays a leap second record.
That is, the satellite signal receiving apparatus 10 is configured to periodically receive leap second information, store it in leap second update data 620, and always convert the GPS time to UTC using the latest leap second. When the inspection mode execution unit 460 executes the inspection mode for displaying leap seconds, the current leap second recorded in the leap second update data 620 of the storage device 60 is displayed on the pointer 12 or the digital display unit, Output in the audio output unit.

[Effects of Second Embodiment]
According to such 2nd Embodiment, the effect similar to the said 1st Embodiment is acquired.
(1) The inspection mode execution unit 460 executes the inspection mode when the latitude and longitude of the position information calculated by the position information calculation unit 440 are specific values. For this reason, it is not necessary for the inspector to execute the inspection mode by operating the button, and the simulation signal generated by the GPS simulator 800 is set according to the inspection mode to be executed, and the operation unit 70 performs the receiving operation in the positioning mode. Therefore, the inspection process can be easily performed. For this reason, the work efficiency in the inspection process in the production line of the factory can be improved.
Further, since the inspection mode is not executed by a button operation, it is possible to reliably prevent the inspection mode from being erroneously executed by a button operation not intended by the user.

(2) Because the specific latitude and longitude instructing the execution of the inspection mode are set at positions near the North Pole and South Pole that are not actually received by general users, and on the Pacific Ocean and the Atlantic Ocean, When the satellite signal of the GPS satellite 100 is actually received outdoors, the inspection mode is rarely executed. That is, the inspection mode can be executed only when a simulated signal from the GPS simulator 800 is received.

(3) Since the record of the reception history in the electronic timepiece 1 can be displayed and output, the inspector can determine in what state the user is using the electronic timepiece 1 and can respond appropriately.
For example, if the reception success rate is low, the inspector can advise the user that the reception success rate increases when receiving in a place where the sky is open as much as possible, and the accurate time can always be displayed. Further, the inspector can determine whether the program (CPU software) is operating normally by checking an automatic reception history or the like.

[Third Embodiment]
Next, 3rd Embodiment of this invention is described based on drawing. In addition, since it is the same as that of the said 1st Embodiment except manual reception processing, the description is abbreviate | omitted.

FIG. 7 is a flowchart illustrating the manual reception process SC10 in the control device 40 according to the third embodiment.
As shown in FIG. 7, the control device 40 performs the processes of SC11 to SC18. Here, the processes of SC11 to SC14, SC16, and SC18 are the same processes as SA11 to SA14, SA16, and SA18 of the first embodiment and SB11 to SB14, SB16, and SB18 of the second embodiment, and thus the description thereof is omitted. .

In SA15 of the first embodiment, execution of the inspection mode is determined based on the calculated altitude value of the position information, and in SB15 of the second embodiment, execution of the inspection mode is performed based on the calculated latitude and longitude values of the position information. I was judging.
On the other hand, when calculating the position information in SC14, the control device 40 of the third embodiment calculates the elapsed time from the reception of the previous position information and the position information from the previous reception to the calculated position information. It is determined whether or not the movement distance meets the conditions for the inspection mode (SC15).

The elapsed time and the moving distance for determining the inspection mode are configured to execute the inspection mode when it is determined that the distance that cannot be moved even by an airplane that is generally the earliest moving means within the elapsed time. Has been.
Thereby, when the position information of the place is acquired, it can be determined whether reception in the normal positioning mode is performed or whether the execution of the inspection mode by the GPS simulator 800 is instructed.
Specifically, in SC15, as shown in Table 3 stored in the inspection mode setting storage unit 670, the elapsed time from the previous reception to the current reception is within one hour, and the previous reception If the movement distance from the position calculated at this time to the position calculated in the current reception is in the range of 2000 to 5999 km, it corresponds to the condition for the inspection mode, and Yes is determined in SC15. On the other hand, if the above condition is not met, SC15 determines No.

  When it is determined No in SC15, the control device 40 corrects the internal time with the acquired time information and the time zone data 650 with the position information by the time correction unit 450, as in the first and second embodiments. (SC16). When the internal time data 630 and the time zone data 650 are corrected, the time data for clock display 640 is also corrected, and the instruction of the hands 12 is also corrected in conjunction with it.

  On the other hand, when it is determined Yes in SC15, the control device 40 determines the type of the inspection mode and executes the inspection (SC17).

[Judgment and execution of inspection mode]
A specific determination and execution method in SC17 will be described with reference to Table 3.
When it is determined Yes in SC15, the inspection mode execution unit 460 of the control device 40 executes the inspection mode corresponding to the elapsed time and the moving distance as shown in Table 3. Since each inspection mode is the same as that of the second embodiment, the description thereof is omitted.

When the elapsed time is within one hour and the moving distance is in the range of 2000 to 2999 km, the inspection mode execution unit 460 executes the inspection mode for displaying the automatic reception history record.
When the elapsed time is within one hour and the moving distance is in the range of 3000 to 3999 km, the inspection mode execution unit 460 executes the inspection mode for displaying the record of the reception success rate.
When the elapsed time is within one hour and the moving distance is in the range of 4000 to 4999 km, the inspection mode execution unit 460 executes the inspection mode for displaying the reception level record.
The inspection mode execution unit 460 executes the inspection mode for displaying leap second records when the elapsed time is within one hour and the moving distance is in the range of 4000 to 4999 km.

[Effects of Third Embodiment]
According to such 3rd Embodiment, the effect similar to the said 1st, 2nd embodiment is acquired.
(1) The inspection mode execution unit 460 executes the inspection mode when the elapsed time and the movement distance obtained by the two reception processes in the positioning mode satisfy the setting conditions. For this reason, it is not necessary for the inspector to execute the inspection mode by operating a button, and the GPS simulator 800 calculates a different place (a position corresponding to the moving distance condition) during the two reception processes. Since it is only necessary to perform the reception operation in the positioning mode with the operation unit 70, the inspection process can be easily performed. For this reason, the work efficiency in the inspection process in the production line of the factory can be improved.
Further, since the inspection mode is not executed by a button operation, it is possible to reliably prevent the inspection mode from being erroneously executed by a button operation not intended by the user.

(2) In this embodiment, it is necessary to perform the receiving operation twice, but the specific movement distance and elapsed time instructing the execution of the inspection mode are inspected for values that cannot be realized by a moving means such as an airplane. Since the conditions for the mode are set, the inspection mode is not executed when the satellite signal of the GPS satellite 100 is actually received outdoors. Therefore, the inspection mode can be executed only when a simulated signal from the GPS simulator 800 is received.

(3) Since the record of the reception history in the electronic timepiece 1 can be displayed and output, the inspector can determine in what state the user is using the electronic timepiece 1 and can respond appropriately. Therefore, as in the second embodiment, the inspector can advise the user on proper usage and determine whether the program is operating normally.

[Fourth Embodiment]
Next, 4th Embodiment of this invention is described based on drawing. The structure of the electronic timepiece according to this embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

FIG. 8 is a block diagram showing a circuit configuration of the satellite signal receiving device 10D in the fourth embodiment, and FIG. 9 is a flowchart showing the manual reception processing SC10 in the control device 40.
The satellite signal receiving device 10D is different from the above embodiments only in that a rewrite mode execution unit 470 (rewrite processing execution unit) is provided in the control device 40 instead of the inspection mode execution unit 460. For this reason, description of components other than the rewrite mode execution unit 470 is omitted.

  As shown in FIG. 9, the control device 40 performs the processes of SD11 to SD17. Here, the processes of SD11 to SD14 and SD16 are the same processes as SA11 to SA14 and SA16 of the first embodiment, and thus the description thereof is omitted.

In each of the above embodiments, the execution of the inspection mode is determined based on at least one of the latitude, longitude, and altitude of the position information calculated based on the received satellite signal.
On the other hand, the control device 40 of the fourth embodiment does not execute the inspection mode, but rewrites various set values (data) stored in the storage device 60 of the electronic timepiece 1 by the rewrite mode execution unit 470. Is to execute.

  When it determines with Yes by SD13, the control apparatus 40 determines whether the height in the calculated positional information is less than -500 m (SD15). When it is determined No in SD15, the control device 40 corrects the internal time based on the acquired time information by the time correction unit 450 and corrects the time zone data 650 based on the position information (SD16). When the internal time data 630 and the time zone data 650 are corrected, the time data for clock display 640 is also corrected, and the instruction of the hands 12 is also corrected in conjunction with it.

On the other hand, when it is determined Yes in SD15, the control device 40 selects a rewriting target, sets data with latitude and longitude values, and executes rewriting (SD17).
Here, the rewrite mode execution unit 470 selects a rewrite target according to the acquired altitude, as shown in Table 4 stored in the inspection mode setting storage unit 670. That is, the rewrite mode execution unit 470 sets the tuning capacitor setting value of the receiving circuit 30 as a rewrite target when the altitude is less than −500 m and −599 m or more.
Moreover, the rewrite mode execution part 470 makes a motor parameter rewriting object, when the said altitude is less than -600 m and -699 m or more.
Furthermore, when the altitude is less than −700 m and −799 m or more, the rewrite mode execution unit 470 sets the time zone setting value as a rewrite target.
The rewrite mode execution unit 470 sets the summer time set value as a rewrite object when the altitude is less than −800 m and −899 m or more.

[Rewriting tuning capacitor setting value]
When the altitude is less than −500 m and −599 m or more, the rewrite mode execution unit 470 rewrites the setting value of the tuning capacitor with the longitude value. That is, as shown in FIG. 10, the GPS antenna 23 is connected to a tuning circuit including three tuning capacitors 235, 236, and 237, switches SW1, SW2, and SW3, and a resistor 238.
In the electronic timepiece 1, the movement in which the satellite signal receiving device 10 is incorporated is made common in order to reduce the cost when manufacturing timepieces of various designs. That is, an internal movement is created, and the shape and material of the outer case 17 are changed according to the design of the watch. At this time, the frequency to be tuned by the GPS antenna 23 varies depending on the material of the outer case 17 and the like.
Therefore, in this embodiment, three tuning capacitors 235, 236, and 237 having different capacities are prepared, and as shown in Table 5, by selecting ON / OFF of each switch SW1, SW2, and SW3, eight kinds of tuning capacitors 235, 236, and 237 are selected. It is set so that it can be tuned to the frequency. The rewrite mode execution unit 470 of the control device 40 sets each switch SW1, SW2, SW3 on / off combination as shown in Table 5 with the calculated longitude value and stores each switch in the storage device 60. Rewrite the set values of SW1, SW2, and SW3.
When the control device 40 of the electronic timepiece 1 is reset and activated, the control device 40 reads on / off setting values of the switches SW1, SW2, and SW3 stored in the storage device 60, and sets the switches SW1 and SW2. , SW3 is turned on / off.
Further, when performing the reception process, the control device 40 reads the on / off of each switch SW1, SW2, SW3 stored in the storage device 60 first, and sets the on / off of each switch SW1, SW2, SW3. Then, reception may be started.

[Rewriting motor parameters]
In the electronic timepiece 1, various kinds of hands 12 are attached for design. Since the rotational moment varies depending on the pointer 12 to be attached, it is necessary to change the setting of the driving torque of the motor.
Therefore, the rewrite mode execution unit 470 rewrites the motor parameter setting value with the longitude value when the altitude is less than −600 m and −699 m or more. That is, as shown in Table 6, when four types of pointers 12 of a thin needle, a thick needle, a long needle, and a special needle are prepared, the motor parameter is switched to four types of setting values of setting 1 to setting 4. Is set. The rewrite mode execution unit 470 rewrites the motor parameter value stored in the storage device 60 by setting the four types of set values with the calculated longitude value.
When the control device 40 of the electronic timepiece 1 is reset and activated, the control device 40 reads the motor parameter stored in the storage device 60 and drives the motor with the read parameter.

[Rewrite block time zone settings]
The electronic timepiece 1 measures the current location by the satellite signal receiving device 10, reads the time zone setting value (time difference data) corresponding to the current location from the time zone data storage unit 680, and sets it in the time zone data 650. The time of the place can be displayed.
Here, as shown in FIG. 11, the time zone data storage unit 680 may divide each area into blocks by latitude and longitude, and set a time zone setting value for each block. By setting the time zone setting value for each block in this way, there is an advantage that the time zone of the whole world can be set while suppressing the storage capacity.

When the set value of the time zone of each block is changed after the electronic timepiece 1 is manufactured and sold, the back cover 20 of the electronic timepiece 1 has been removed so far, the circuit board 25 is accessed, and the time zone data is stored. It was necessary to rewrite the data in the section 680.
On the other hand, in this embodiment, data can be rewritten without removing the back cover 20 according to altitude, latitude, and longitude values.

That is, when the altitude is less than −700 m and −799 m or more, the rewrite mode execution unit 470 selects a block to be rewritten with the latitude value, and rewrites the time zone setting value of the selected area with the longitude value.
That is, as shown in Table 7, a block (region) divided according to the value of latitude is selected. In Table 7, when the latitude is in the range of 69.9 degrees north latitude or more and less than 70.0 degrees, the rewrite mode execution unit 470 selects the upper left area 1 from the blocks shown in FIG. When the latitude is in the range of north latitude 70.0 or more and less than 70.1 degrees, the rewrite mode execution unit 470 selects the region 2 located on the right side of the region 1.
In addition, the rewrite mode execution unit 470 rewrites the set values of the time zones of the regions 1 and 2 with the received longitude value. For example, when region 1 is selected by latitude and longitude is in the range of 3.5 to 3.9 degrees east longitude, the current setting value of +3.0 hours is rewritten to +3.5 hours.
It should be noted that the correspondence table between the longitude and the set value in Table 7 may be prepared for each region and stored in the time zone data storage unit 680 since the numerical value and the number of the set value vary depending on each region.

[Rewriting the time zone settings of the representative city]
When rewriting the time zone, a representative city in a region that uses a common local standard time may be selected and set. For this reason, when the altitude is less than −700 m and −799 m or more, the rewrite mode execution unit 470 selects the city to be rewritten with the latitude value, and rewrites the time zone setting value of the selected city with the longitude value. Also good.
That is, as shown in Table 8, the city for which the time zone is set is selected according to the latitude value. In Table 8, since the latitude is in the range of north latitude 89.9 to 90.0 degrees, the rewrite mode execution unit 470 selects Tokyo as the city.
In addition, the rewrite mode execution unit 470 rewrites the set value of the time zone of the selected city with the received longitude value. For example, in the case of 9.5 to 9.9 degrees east longitude, the current setting value of +9.0 hours is rewritten to +9.5 hours.
The table of correspondence between the longitude and the set value in Table 8 may be prepared for each city and stored in the time zone data storage unit 680 because the numerical value of the set value varies depending on each city.

[Rewriting daylight saving time settings]
When rewriting daylight saving time settings, select and set the area to be rewritten. For this reason, when the altitude is less than −800 m and −899 m or more, the rewrite mode execution unit 470 selects a region to be rewritten with a latitude value, and determines whether or not there is daylight saving time in the region selected with a longitude value. rewrite.
That is, as shown in Table 9, the rewrite mode execution unit 470 selects an area for which daylight saving time is set according to a latitude value. In Table 9, since the latitude is in the range of north latitude 89.9 to 90.0 degrees, the rewrite mode execution unit 470 selects Japan as the region to be selected.
In addition, the rewrite mode execution unit 470 sets and rewrites the summer time setting value of the selected region with the received longitude value. For example, the rewrite mode execution unit 470 sets “no daylight saving time” in the range of 7.5 to 7.9 degrees east longitude and sets “daylight saving time” in the range of 8.0 to 8.4 degrees east longitude. The time is “+1 hour”, and the daylight saving time is “from 2 am on the second Sunday in March to 2 am on the first Sunday in November” based on the local time.
It should be noted that since the contents of the correspondence table between the longitude and the set value in Table 9 vary depending on each region, it may be prepared for each region and stored in the time zone data storage unit 680.

[Effects of Fourth Embodiment]
According to such 4th Embodiment, the following effects are obtained similarly to the said 1st-3rd embodiment.
(1) The rewrite mode execution unit 470 selects the rewrite mode (rewrite process) according to the altitude of the position information calculated by the position information calculation unit 440, and sets the data rewrite target and rewrite data according to the latitude and longitude. ing.
For this reason, when various data are rewritten after the manufacture and sale of the electronic timepiece 1, there is no need to collect the electronic timepiece 1 at the service center and open the back cover 20 to access the circuit board 25 as in the past. Since it is only necessary to generate a simulation signal with the GPS simulator 800 and perform manual reception processing with the electronic timepiece 1, the rewriting process can be easily performed. For this reason, the rewriting work can be easily performed not only at the service center but also at the store of the watch store, and the work efficiency can be improved. Note that the GPS simulator 800 is required for data rewriting, but since the GPS simulator 800 itself can use general-purpose products that are generally sold, the cost can be reduced.
Moreover, since it is not necessary to open and close the back cover 20, it can also prevent that the waterproofness of the electronic timepiece 1 falls.

(2) Since the specific altitude for instructing execution of the rewrite mode is set to be less than −500 m which cannot be actually received, the rewrite mode is set when the satellite signal of the GPS satellite 100 is actually received outdoors. Never executed. That is, the inspection mode can be executed only when a simulated signal from the GPS simulator 800 is received.

(3) When rewriting the time zone and daylight saving time setting values, the area to be rewritten can be selected with the latitude value, and the setting value can be rewritten with the longitude value. It can be easily rewritten only by receiving three advanced data. Therefore, the efficiency of rewriting work can be improved.

[Other Embodiments]
In addition, this invention is not limited to the structure of each said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention.
For example, in the first to fourth embodiments, the inspection mode or the rewrite mode is executed by the manual reception process. However, the reception process is not limited to the manual reception process, and a reception process that can calculate position information such as latitude, longitude, and altitude is performed. Anything is acceptable.
In the second and third embodiments, the process for displaying information related to reception is performed as the inspection mode. However, the present invention is not limited to this, and the inspection mode of the first embodiment may be performed. In the first embodiment, the inspection mode of the second and third embodiments may be performed. Further, other inspection modes may be performed.
Further, for example, in the first to third embodiments, one inspection mode is executed by the manual reception process. However, a plurality of inspection modes may be continuously executed. That is, when one inspection mode is executed by the manual reception process and finished, the process is temporarily stopped. Then, for example, when the inspector presses the button 15 once, the next inspection mode is executed. When this inspection mode ends, the process is temporarily stopped, and when the button 15 is pressed, the next inspection mode is executed. The above processing is repeated, and when all the set inspection modes are completed or when the button 16 for canceling the inspection mode is pressed halfway, the inspection mode is ended and the clock mode for measuring and displaying the time is displayed. You may move to.
Furthermore, a series of inspection modes may be continuously executed without pausing when one inspection mode is completed.

In the fourth embodiment, when the position information is calculated based on the satellite signal received by the satellite signal receiving device 10, the rewrite target is selected based on the altitude value, and the latitude is set in advance. I was selecting rewrite data. On the other hand, after entering the rewrite mode with the altitude value obtained by the first manual reception and selecting the rewrite target, the GPS simulator 800 is switched to the mode for transmitting specific numerical values of latitude and longitude, and the satellite signal The reception apparatus 10 may perform manual reception processing again, and the position information calculation unit 440 may directly receive the latitude and longitude numerical values without directly calculating the position information, and directly rewrite the data with the values.
For example, when rewriting the time zone determined for each block, the area of the block may be selected by latitude and the time zone setting value may be directly set by longitude. For example, when the time zone is +4 hours with respect to UTC, 4 degrees east longitude is set and transmitted. When the time zone is +5 hours, 5 degrees east longitude is set and transmitted. Also, when the time zone is -3 hours with respect to UTC, 3 degrees west longitude is set and transmitted. When the time zone is -7 hours, 7 degrees west longitude is set and transmitted. That is, it is only necessary to specify the time zone plus / minus of the time zone by east longitude and west longitude, and specify the time by the numerical value of longitude.

Further, after entering the rewrite mode with the altitude value obtained by the first manual reception and selecting the rewrite target, the GPS simulator 800 is switched to the mode for transmitting specific numerical values of latitude, longitude and altitude, and the satellite signal The reception device 10 may perform manual reception processing again to directly select a city whose time zone is to be rewritten with the latitude and longitude of the city and directly rewrite the time zone time difference with the altitude value.
For example, it is possible to select Tokyo at 35 degrees 41 minutes north latitude and 139 degrees 45 minutes east longitude, and rewrite the Tokyo time difference to +9.5 hours with respect to UTC at an altitude of +9.5 m.

In the fourth embodiment, four types of data, that is, a tuning capacitor setting value, a motor parameter, a time zone setting value, and a daylight saving time setting value are selected and rewritten. However, at least one of these data is rewritten. It may be set.
Furthermore, the data rewrite target is not limited to the four types of the fourth embodiment. For example, various parameters used in the program may be rewritten. In this case, even if there is a problem with parameter settings, it can be easily handled.

Further, the rewrite mode execution unit 470 may be able to rewrite a part of the program in the rewrite mode in order to optimize the software program of the control device 40.
Furthermore, the rewrite mode execution unit 470 may store a plurality of types of software programs of the control device 40 in the storage device 60 and rewrite the setting value for selecting the program to be executed in the rewrite mode. .

When the position information calculation unit 440 determines that the error is large when calculating the latitude, longitude, and altitude, the inspection mode execution unit 460 and the rewrite mode execution unit 470 are set not to execute the inspection mode and the rewrite mode. May be.
In addition, when the position information calculation unit 440 calculates the latitude, longitude, and altitude, only the three satellite signals can be received and the 2D positioning (two-dimensional positioning) is performed. The mode execution unit 470 may be set not to execute the inspection mode or the rewrite mode.
Further, when the position information calculation unit 440 calculates latitude, longitude, and altitude, when it is considered that the accuracy is low, such as when the number of satellites is small or the signal level is low, the inspection mode execution unit 460 or the rewrite mode execution unit 470 may be set not to execute the inspection mode or the rewrite mode.
In the present invention, the inspection mode and the rewrite mode are executed when latitude, longitude, and altitude, which are hardly obtained by normal positioning, are acquired. Therefore, when the actual satellite signal of the GPS satellite 100 is received and positioning is performed outdoors, the inspection mode and the rewrite mode are not executed. However, when the signal level of the satellite signal is low or the number of satellites is small, and the latitude, longitude, and altitude calculated by the position information calculation unit 440 include errors, it corresponds to the execution condition of the inspection mode and rewrite mode There is a possibility that.
On the other hand, if it is determined that the inspection mode or the rewrite mode is not executed when it is determined that the error is large as in this modification, the satellite signal of the actual GPS satellite 100 is received outdoors. In some cases, it is possible to prevent the inspection mode and the rewrite mode from being executed by mistake.

In the above embodiment, the GPS satellite has been described as an example of the position information satellite. However, as the position information satellite of the present invention, not only the GPS satellite but also Galileo (EU), GLONASS (Russia), Hokuto (China), etc. Other global navigation satellite systems (GNSS), geostationary satellites such as SBAS, and position information satellites that transmit satellite signals including time information such as quasi-zenith satellites may be used.
The setting of the type of satellite used in the various position information satellites may be rewritten using the GPS simulator 800 for each country where the electronic timepiece 1 is shipped. For example, in Japan and its surrounding countries, it is possible to improve the positioning accuracy by receiving satellite signals of quasi-zenith satellites in addition to the GPS satellite 100. For this reason, the electronic timepiece 1 to be sold to Japan and surrounding countries may be set using the GPS simulator 800 so that the satellite signal of the quasi-zenith satellite is also acquired. With this setting, in the electronic timepiece 1 used in an area where the quasi-zenith satellite cannot be received, the problem is that the reception time is long and the power is consumed in order to receive the satellite signal of the quasi-zenith satellite. it can.

  Further, the control device 40 of the electronic timepiece 1 may be provided with both the inspection mode execution unit 460 of the first to third embodiments and the rewrite mode execution unit 470 of the fourth embodiment. In this case, for example, as shown in Table 10, an altitude value for executing the inspection mode may be different from an altitude value for executing the rewrite mode.

The satellite signal receiving device of the present invention and the electronic timepiece having the satellite signal receiving device are not limited to wristwatches, and are driven by a battery or the like such as a portable GPS receiver used for mobile phone, mountain climbing, etc. It can be widely used in electronic devices that receive satellite signals transmitted from information satellites.
Further, although an electronic timepiece has been disclosed as an electronic device, the present invention is not limited to this, and the present invention can be applied to other electronic devices that operate by receiving satellite signals.
