[Problems to be Solved by the Invention] [0007] In order to drive various types of sensors and circuit components, such devices for competitive sports balls such as basketballs are considered to be built in the primary battery as a power supply circuit. At this time, the primary battery is placed near the center of the ball in consideration of the weight balance. [0008] Such a device, because it is difficult to exchange the primary battery, and it is difficult to hide the power switch inside, and even if it is difficult to carry out its operation, it has been used in the system that will contain the microcomputer in non-use. The method by which the circuit is set to sleep. However, in order to use the device for a long period of time, even if the device is in a sleep state, the power consumption often reaches a level that cannot be ignored. [0009] In order to solve such a problem, although it is considered to supply power from the outside using the short-range communication technology, since it is difficult to form a sufficiently large antenna for short-distance communication for power supply, the power supply using the short-range communication technology is difficult. Moreover, when such a power supply method is to be employed, there is a problem that the cost rises. [0010] The present invention has been made in view of the circumstances of the prior art, and an object of the present invention is to provide a power source starting system that minimizes the power consumption of a primary battery without increasing the cost of the device. [Means for Solving the Problem] The power source starting circuit of the present invention which solves the above-described problems includes a power source circuit, a power source control unit including an acceleration sensor and a switch circuit, a measuring circuit, and the power source control unit and the aforementioned amount. a main control unit of the measuring circuit, a housing for housing the power supply circuit and the power supply control unit, the measuring circuit and the main control unit; the power supply circuit is configured by a primary battery; and the power starting system is applied to the acceleration sensing device The acceleration of the device controls the aforementioned switching circuit to activate the aforementioned main control unit; when the predetermined acceleration value is detected for a predetermined duration, the switching circuit is turned on. [0012] In the power-starting system configured as described above, when the predetermined acceleration value is detected for a predetermined duration, the switching circuit is turned on, so that the switching circuit can be turned on without the artificial acceleration occurring daily. Therefore, the possibility of erroneous activation can be reduced while the device is surely activated. As a result, it is possible to provide a power source starting system that minimizes the power consumption of the primary battery without increasing the cost of the device. Further, in the above configuration, the acceleration detected during the duration is an acceleration caused by the power supply starting system itself falling. [0014] The power source activation system configured as described above can open the switch circuit by simply pushing the device that houses the power source activation system up and down, and can easily activate the device. Further, in the above configuration, the acceleration detected during the duration is an acceleration caused by the power supply starting system itself rotating. [0016] The power source activation system configured as described above can open the switch circuit by rotating the device that houses the power source activation system itself only on a table or the like, and can easily activate the device. Further, in the above configuration, the power supply voltage is supplied only to the acceleration sensor from the primary battery until the switching circuit is turned on by the acceleration sensor. [0018] The power-starting system configured in this way, since the switching circuit is turned on, only the power supply voltage is supplied to the acceleration sensor, and the power supply voltage is not supplied to the main control unit and the measuring circuit, and the standby state before the device is started can be reduced as much as possible. Consume power. Further, in the above configuration, the wireless communication unit that communicates with the outside is provided. [0020] The power activation system configured as described above has a wireless communication unit, and can wirelessly transmit the measurement result obtained by the measurement circuit to the outside. Further, in the above configuration, the power supply control unit includes a switch control circuit; and after the activation, when communication between the wireless communication unit and the outside is not performed within a predetermined waiting time, the main control unit is provided. The control signal is invalid, and the aforementioned switching circuit is turned off by the aforementioned switch control circuit. [0022] The power-starting system configured as described above can prevent useless power consumption even if the device is erroneously activated, because the switching circuit is turned off when communication is not performed. [0023] Further, in the above configuration, it is mounted in a core for a sensor ball incorporated in a ball for ball technique. [0024] The power source starting system thus constructed is suitable for use for a long time because it is suitable for use in a core for a sensor ball. [Effects of the Invention] [0025] The power-on starting system of the present invention is configured such that when a predetermined acceleration value is detected for a predetermined duration, the switch circuit is turned on, and the switch can be prevented from being caused by daily artificial acceleration. The circuit is turned on. Therefore, the possibility of erroneous activation can be reduced while the device is surely activated. As a result, it is possible to provide a power source starting system that minimizes the power consumption of the primary battery without increasing the cost of the device.

[0027] Hereinafter, the present invention will be described with reference to the accompanying drawings. The power source starting system of the present invention is a power source starting system for a device built in a measuring circuit while using a primary battery as a power supply circuit. A power source activation system 100 mounted in the sensor ball core body 90 as the embodiment will be described.

In particular, in order to know how the ball thrown by the pitcher of the baseball rotates, and how the rotation changes the orbit of the ball, the developer. In addition, a power source startup object such as a ball incorporating the power source activation system 100 will be referred to as a device. [0028] The use of the power source activation system of the present invention is not limited to the embodiment described below, and can be appropriately changed. In addition, in the description of the drawings, the right side, the left side, the rear side, the front side, the upper side, and the lower side are described for convenience, but the +X side is shown in each drawing. The -X side, the +Y side, the -Y side, the +Z side, and the -Z side, the direction in which the product is placed and the direction in use are not limited thereto. [0029] First, the configuration of the power source activation system 100 in the device and the configuration of the core body 90 for the sensor ball will be described with reference to FIGS. 1 to 4. 1 is a block diagram showing a configuration of a power source starting system 100, FIG. 2 is a perspective view showing a sensor core ball 90 for mounting the power source starting system 100, and FIG. 3 is a core body 90 for a sensor ball. Floor plan. Moreover, FIG. 4 is an exploded perspective view showing the relationship between the core body 95 and the case 60 which constitute the core body 90 for the sensor. Further, in FIGS. 2 and 3, the case 60 is made transparent. [0030] As shown in FIG. 1, the power source activation system 100 includes a power supply control unit 10 including an acceleration sensor 11, a switch circuit 13, and a switch control circuit 15, a measurement circuit 30, and wireless communication with the outside. The communication unit 70, the control power supply control unit 10, the measurement circuit 30, and the main control unit 20 of the wireless communication unit 70, and the power supply circuit 40 for supplying the power supply voltage V1 to each circuit. The power supply circuit 40 is constituted by a primary battery 41. [0031] The power supply control unit 10, the power supply circuit 40, the measurement circuit 30, the main control unit 20, and the wireless communication unit 70 constituting the power activation system 100 are disposed on the wiring substrate 50 as shown in FIGS. 2 and 3. The state is mounted on the core body 90 for the sensor ball. Further, the core body 90 for the sensor ball is constituted by a core body 95 and a case 60 as shown in FIG. [0032] The case 60 is formed by a polycarbonate resin or the like. The case 60 is formed in a spherical shape in order to facilitate winding in the manufacturing process of the baseball ball, and the core body 95 is housed in the case 60. The case 60 that houses the core body 95 is formed in the same spherical shape, and is housed in a ball of a baseball in a state of being accommodated in an elastic member (not shown) that is larger than the case 60. As shown in FIG. 4, the case 60 is composed of two of a hemispherical first case 60a and a hemispherical second case 60b. Then, the core body 90 for the sensor ball is formed by sandwiching the hemispherical first case 60a and the hemispherical second case 60b with the core body 95. The wiring board 50 is generally formed by a rigid flexible board. As shown in FIG. 2, the wiring board 50 is formed of a flexible plurality of flexible portions 51 and a plurality of rigid rigid portions 53 having rigidity. The rigid portion 53 of the wiring substrate 50 is formed to be thicker than the thickness of the flexible portion 51. One of the rigid portions 53 serves as a circuit board 55 having a substrate surface on the X-Y plane. [0035] As shown in FIG. 2 and FIG. 3, a plurality of components are disposed on one substrate surface (upper surface) of one of the circuit boards 55, which is a part of the wiring substrate 50, on the other substrate surface of the circuit board 55 ( On the lower side), the above primary battery 41 is mounted. [0036] The primary battery 41 is disposed at a substantially center of the case 60, and its surface is formed into a disk shape of a metal body, and has the heaviest quality as compared with all other members. A button battery is generally used as the primary battery 41. [0037] In the primary battery 41, two electrodes 41a of a positive electrode and a negative electrode are provided, and the two electrodes 41a are mechanically electrically connected to the circuit substrate 55 by solder. A double-sided adhesive (not shown) is disposed between the upper surface of the primary battery 41 and the lower surface of the circuit board 55, and the circuit substrate 55 is bonded to the primary battery 41, including the primary battery 41 and the circuit substrate. The wiring board 50 of 55 is fixed to the case 60. The measurement circuit 30 is configured by a measurement member 31 including a measurement acceleration sensor 31a, an angular velocity sensor 31b, and a geomagnetism sensor 31c. The measurement acceleration sensor 31a and the angular velocity sensor 31b are mounted on the center position of the upper surface of the circuit board 55 in the measurement member 31. Further, in the sensor core body 90 for measurement, the measurement acceleration sensor 31a and the angular velocity sensor 31b are housed in one package. [0040] The measurement acceleration sensor 31a is capable of detecting the stationary state of the baseball. Also, the angular velocity sensor 31b can detect the motion of the ball. Since the measurement acceleration sensor 31a and the angular velocity sensor 31b are not affected by the metal body, even if the metal body, that is, the primary battery 41, is nearby, measurement can be performed without problems. In addition, since the measurement acceleration sensor 31a and the angular velocity sensor 31b are mounted on the center of one of the substrate surfaces of the circuit board 55, it is difficult to receive centrifugal force and can be accurately measured. The geomagnetic sensor 31c of the measuring member 31 is mounted on the position rigid portion 53 located at the lowermost side among the plurality of rigid portions 53 of the wiring board 50. The geomagnetism sensor 31c is capable of detecting the number of rotations of the ball and the change in the rotation axis (rotation direction). [0042] As the measuring member 31, the measuring acceleration sensor 31a, the angular velocity sensor 31b, and the geomagnetism sensor 31c are capable of detecting from the start of the pitching operation of the pitcher to the time when the catcher catches the ball. How does the ball's own axis rotate? The wireless communication unit 70 is configured by the first wireless communication unit 71 and the second wireless communication unit 72. As shown in FIG. 3, the first wireless communication unit 71 is configured by a first wireless communication circuit 73, a first wireless communication antenna 75, and a communication electronic component 79. Further, the second wireless communication unit 72 is configured by the second wireless communication circuit 74, the second wireless communication antenna 76, and the communication electronic component 79. As shown in FIGS. 2 and 3, the plurality of communication electronic components 79 are mounted on the upper surface of the circuit board 55, and the first wireless communication antenna 75 is along the longitudinal direction of the flexible portion 51 of the wiring substrate 50. form. The first wireless communication circuit 73 is formed by a wiring pattern (not shown) provided in the communication electronic component 79 and the circuit board 55 for the first wireless communication unit 71. The second wireless communication antenna 76 for the second wireless communication unit 72 is formed on the rigid portion 53 located below the primary battery 41. The second wireless communication circuit 74 is formed by a wiring board pattern (not shown) provided in the communication electronic component 79 and the circuit board 55 for the second wireless communication unit 72. [0046] The first wireless communication unit 71 has a wireless communication function called Bluetooth (registered trademark), and is set to communicate with the outside. Therefore, the measurement result data obtained by the measurement member 31 formed by the measurement acceleration sensor 31a, the angular velocity sensor 31b, and the geomagnetism sensor 31c can be transmitted to the outside. The second wireless communication unit 72 is called NFC (Near Field Radio Communication) and has a short-range wireless communication function that is shorter than the communication distance of the first wireless communication unit 71. The second wireless communication unit 72, that is, NFC, is used when the device is required to be reset. The power supply control unit 10 including the acceleration sensor 11, the switch circuit 13, and the switch control circuit 15 is formed near the center of one of the substrate faces of the circuit board 55 as shown in FIGS. 2 and 3 . Further, the main control unit 20 including the microcomputer 21 and the memory 23 is also formed on one substrate surface of the circuit board 55. The details of the power supply control unit 10 and the main control unit 20, which are main components of the power activation system 100, will be described later. [0049] Next, a detailed configuration of the main part of the power activation system 100 and an operation thereof will be described with reference to FIGS. 1 and 2 . [0050] As described above, the power source control unit 10 in the power source activation system 100 is configured by the acceleration sensor 11, the switch circuit 13, and the switch control circuit 15. As shown in FIG. 1, the acceleration sensor 11 is provided with a power supply voltage input terminal 11a, a start signal output terminal 11b, and a control signal input terminal 11c. The primary battery 41 constituting the power supply circuit 40 is connected to the power supply voltage input terminal 11a, and the power supply voltage V1 is constantly supplied from the primary battery 41. The start signal output terminal 11b is connected to the switch circuit 13, and can output a start signal S1 for turning on the switch circuit 13. The control signal input terminal 11c is connected to the microcomputer 21 of the main control unit 20, and can input the control signal S2 from the microcomputer 21. Further, after the power is turned on, the control signal S2 is input from the microcomputer 21 to the acceleration sensor 11, and the start signal S1 is invalidated. The acceleration sensor 11 is configured to be capable of detecting accelerations in three directions (X, Y, and Z directions, which are referred to in FIG. 2) that are perpendicular to each other, and includes the sensing of the mounted acceleration sensor 11 When the device for the ball core 90 moves in at least one direction in the X, Y, and Z directions, the operation is detected, and after the operation is detected, the start signal S1 is output. [0054] The switching circuit 13 is provided with a power supply voltage input terminal 13a, a power supply voltage output terminal 13b, and a signal input terminal 13c. The switch circuit 13 is turned on when the start signal S1 from the above-described acceleration sensor 11 is input to the signal input terminal 13c. [0055] The power supply voltage input terminal 13a is connected to the primary battery 41, and the power supply voltage V1 is constantly applied to the power supply voltage input terminal. Further, the power source voltage output terminal 13b of the switch circuit 13 is connected to the main control portion 20. When the switch circuit 13 is turned on, the power source voltage V1 applied to the power source voltage input terminal 13a is supplied to the main control portion 20. [0056] The switch control circuit 15 has a control signal input terminal 15a and a switch control signal output terminal 15b. The control signal input terminal 15a is connected to the microcomputer 21 of the main control portion 20, and the switch control signal output terminal 15b is connected to the signal input terminal 13c of the switch circuit 13. The switch control circuit 15 can output the switch control signal S3 by the input of the control signal S2 from the microcomputer 21. [0057] The power supply control unit 10 constitutes a wired circuit as a whole, and the activation signal S1 from the acceleration sensor 11 is input to the switch circuit 13. After the switch circuit 13 is turned on, the control signal S2 is input from the microcomputer 21 to the switch control circuit 15, The switch control circuit 15 outputs the switch control signal S3 to enable the switch circuit 13 to remain on. As a result, after the device is started, the power supply to the main control unit 20 is continued. The main control unit 20 includes a microcomputer 21 and a memory 23 connected to the microcomputer 21, and part or all of the data obtained by the measurement unit 31 in the measurement circuit 30 is recorded in the memory 23. The microcomputer 21 controls the acceleration sensor 11 and the switch control circuit 15 after the device is activated by the control signal S2 output from the microcomputer 21. The measurement circuit 30 and the wireless communication unit 70 are also connected to the microcomputer 21 in the main control unit 20, and the operations of the measurement circuit 30 and the wireless communication unit 70 are also controlled by the microcomputer 21. [0060] Next, a method of starting up the power-on system 100 (a first starting method and a second starting method) and subsequent control will be described with reference to FIGS. 1 and 5. Fig. 5(a) is a graph showing the relationship between the acceleration value G1 and the duration T1 used in the first starting method, and Fig. 5(b) is a graph showing the acceleration value G2 used in the second starting method and continuing. A graph of the relationship between time T1. [0061] The power source starting system 100 is a power source starting system that activates the main control unit 20 by controlling the switching circuit 13 in accordance with the acceleration applied to the acceleration sensor 11 of the power source control unit 10 as the starting method. In the power activation system 100, only the acceleration sensor 11 is used to activate the device, and after the device is activated, the microcomputer 21 of the main control unit 20 controls the various components in the device. [0062] As before, before the power-on system 100 is activated, that is, until the switch circuit 13 is turned on by the acceleration sensor 11, although the power supply voltage V1 is supplied to the acceleration sensor 11, the main control unit is used. The power supply voltage V1 is not supplied to the measurement circuit 30, the wireless communication unit 70, and the like. [0063] After the device that houses the power activation system 100 itself is thrown up, the device will fall freely after reaching the height. After the device is pushed up, although an acceleration is applied to the acceleration sensor 11 in the device, the acceleration is gradually attenuated in the free fall to almost zero. [0064] The first starting method in the power-starting system 100 in the core body 90 for the sensor ball is to cause the power-on system 100 to drop itself by dropping the device that houses the power-on system 100 itself, as shown in the figure. 5(a), in the free fall, the acceleration applied to the acceleration sensor 11 is equal to or lower than the acceleration value G1 which is a predetermined value, and the state below the acceleration value G1 continues for the predetermined duration T1. After the condition, the switching circuit 13 is turned on. [0065] After the state below the acceleration value G1 continues for the duration T1, as shown in FIG. 1, the start signal S1 is input from the start signal output terminal 11b of the acceleration sensor 11 to the signal input terminal 13c of the switch circuit 13. The switch circuit 13 is turned on. Further, inside the acceleration sensor 11, the acceleration value of the acceleration applied to the acceleration sensor 11 itself and its duration can be detected. Therefore, the activation signal S1 can be output only by the acceleration sensor 11 by being consistent with the above conditions. Therefore, in the power supply control unit 10, there is no particular need to perform a circuit for controlling the output of the enable signal S1. When the switch circuit 13 is turned on, the main control unit 20 supplies the power supply voltage V1, and the microcomputer 21 starts operating. Thereafter, the control signal S2 is supplied from the microcomputer 21 to the control signal input terminal 15a of the switch control circuit 15. The switch control signal S3 is output from the switch control circuit 15 to the switch circuit 13 by inputting the control signal S2 to the switch control circuit 15. By inputting the switch control signal S3 to the switch circuit 13, the on state of the switch circuit 13 can be maintained. Further, at the same time, the control signal S2 is supplied from the microcomputer 21 to the acceleration sensor 11, and the activation signal S1 output from the acceleration sensor 11 becomes invalid. When the power supply voltage V1 is supplied to the main control unit 20, the power supply voltage V1 is supplied to the measurement circuit 30 and the wireless communication unit 70, and the control of the main control unit 20 is performed to perform various amounts of the measurement circuit 30. The communication between the wireless communication unit 70 and the outside is measured. [0070] If it is necessary to stop the power supply after the startup of the device, the main control unit 20 performs control to turn off the power. When the power supply is stopped, the control signal S2 from the microcomputer 21 to the switch control circuit 15 is invalidated. Therefore, the control signal S3 from the switch control circuit 15 also becomes invalid. At this time, since the activation signal S1 from the acceleration sensor 11 to the switching circuit 13 is also invalidated, the switching circuit 13 is turned off. Since the switch circuit 13 is in the off state, the supply of the power supply voltage V1 to the main control unit 20, the measurement circuit 30, and the wireless communication unit 70 is stopped. Further, the instruction to stop the power supply to the main control unit 20 is performed by the short-range wireless communication by the second wireless communication unit 72. [0071] The second starting method in the power activation system 100 in the core body 90 for the sensor ball is to rotate the power source starting system 100 itself, and the state of the predetermined acceleration value G2 or more in the rotation is for a predetermined duration. A method of turning on the switch circuit 13 when T1 is detected. After the apparatus that houses the power source activation system 100 is rotated on a table or the like, the apparatus receives an acceleration from the acceleration sensor 11 by the centrifugal force caused by the rotation, and then the acceleration rises, and gradually decays after exceeding the acceleration value. In the second activation method, as shown in FIG. 5(b), the acceleration applied to the acceleration sensor 11 during the rotation of the device is equal to or greater than the acceleration value G2 which is a predetermined value, and the acceleration value G2 or higher. After the predetermined duration T1 continues, the switching circuit 13 is turned on. That is, after the state above the acceleration value G2 continues for the duration T1, as shown in FIG. 1, the activation signal S1 is input from the acceleration sensor 11 to the signal input terminal 13c of the switch circuit 13, and the switch circuit 13 is turned on. . [0074] The switching circuit 13 is turned on. This is also the same as the case of the first startup method described above. Therefore, by using the first starting method or the second starting method described above, the device can be surely activated, and the possibility of erroneous activation can be reduced. However, if it is assumed that the device is erroneously activated before the first startup method or the second startup method is used, the power of the primary battery 41 is wasted. Therefore, in the present invention, even when the device is erroneously activated, the power of the primary battery 41 can be prevented from being wasted. [0076] In the embodiment of the present invention, the sensor ball core body 90 on which the power source activation system 100 is mounted is obtained by the measurement circuit 30 incorporating the ball ball as described above, in order to obtain the data. It is taken out and wirelessly transmitted to the outside through the first wireless communication unit 71 in the wireless communication unit 70. Therefore, it is necessary to use the wireless communication unit 70. In other words, if the wireless communication unit 70 is not used, the measurement circuit 30 is not operated, and it is not necessary to activate the device in advance. In the present invention, after the device is activated, the microcomputer 21 detects the presence or absence of communication by the wireless communication unit 70, and when communication between the wireless communication unit 70 and the outside is not performed within the predetermined waiting time T2, The control signal S2 from the microcomputer 21 of the main control unit 20 is deactivated, and the switch circuit 13 is turned off by the switch control circuit 15. Therefore, the supply of the power source voltage V1 to the main control unit 20, the measurement circuit 30, and the wireless communication unit 70 is stopped. As a result, power waste of the primary battery 41 can be prevented. [Modification of Embodiment] [0078] Hereinafter, a modification of the embodiment of the present invention will be described with reference to Fig. 6 . The power source activation system 110 according to the modification of the present invention can be applied to a volcanic activity monitoring system or the like when the monitoring device of the power source activation system 110 is mounted, for example, in a place where a person such as a volcano cannot enter. Further, while the primary battery is used as the power supply circuit, the power activation system of the device built in the measurement circuit is the same as the power activation system 100 described above. [0079] Referring to Fig. 6, the configuration of the power source activation system 100 in the device will be described. FIG. 6 is a block diagram showing the configuration of the power source starting system 110. The difference between the power activation system 110 and the power activation system 100 described above is only the internal configuration of the measurement circuit 37 and the wireless communication unit 77 of the power activation system 110, and the basic configuration is the same as that of the power activation system 100. Therefore, the description of the same portions as those of the power source starting system 100 will be omitted. The monitoring device on which the power source activation system 110 is mounted is placed in the vicinity of the crater of the volcano, for example, from a drone or the like, and the monitoring device is activated in the middle of the fall. After that, the power source activation system 110 that has fallen in the vicinity of the crater of the volcano is subjected to various measurements such as air pressure and temperature until the end of the life of the primary battery 41, and communication is performed to transmit the measurement result to the outside. As shown in FIG. 6, the power source activation system 110 includes a power source control unit 10 including an acceleration sensor 11, a switch circuit 13, and a switch control circuit 15, a measurement circuit 37, and wireless communication with the outside. The communication unit 77, the control power supply control unit 10, the measurement circuit 37, and the main control unit 20 of the wireless communication unit 77, and the power supply circuit 40 for supplying the power supply voltage V1 to each circuit. The power supply circuit 40 is constituted by a primary battery 41. The power source control unit 10, the power source circuit 40, the measurement circuit 37, the main control unit 20, and the wireless communication unit 77 constituting the power source activation system 110 are housed in a casing (not shown). Although the casing may have a spherical shape as in the case of the power activation system 100, in order to easily spur the ground when falling near the crater of the volcano, the weight of the front portion is weighted while the front end portion is pointed. It is preferable that the shape is a substantially cylindrical shape as a whole. The measurement circuit 37 is configured by a measurement member 31 including a measurement acceleration sensor 31a, an angular velocity sensor 31b, a geomagnetism sensor 31c, and an environmental sensor 31d. The measurement acceleration sensor 31a and the angular velocity sensor 31b can detect the operation of the device, and can measure minute movements of the earth's crust caused by seismic activity of the volcano. Further, the geomagnetic sensor 31c is capable of detecting a change in geomagnetism caused by a change in the crust. The environmental sensor 31d includes a temperature sensor, a humidity sensor, a barometric sensor, and the like, and is capable of measuring changes in temperature, humidity, air pressure, and the like. The wireless communication unit 77 is configured by the first wireless communication unit 71 similarly to the case of the power activation system 100. The first wireless communication unit 71 has a wireless communication function called Bluetooth (registered trademark), and is set to communicate with the outside. Therefore, the measurement result data obtained by the above-described various measuring members 31 can be transmitted to the outside. Further, the second wireless communication unit 72 existing in the power activation system 100 may not be mounted. [0086] Next, an operation of the power activation system 110 will be described with reference to FIG. 6. [0087] The startup method of the power activation system 110 is the same as the first startup method of the power activation system 100. In order to cause the power activation system 110 to fall itself, the predetermined acceleration value G1 is detected in the fall for a predetermined duration T1. At the time, the switching circuit 13 is turned on. [0088] After the device that houses the power activation system 110 itself is dropped from the drone or the like, the acceleration is gradually applied to the acceleration sensor 11 in the device after the device is dropped, but the acceleration is gradually attenuated during the free fall. Reached almost zero. [0089] In the activation method, as shown in FIG. 5(a), in the free fall, the acceleration applied to the acceleration sensor 11 is equal to or lower than the acceleration value G1 which is a predetermined value, and the acceleration value G1 or more is in the state of After the predetermined duration T1 continues, the switching circuit 13 is turned on. That is, after the state below the acceleration value G1 continues for the duration T1, as shown in FIG. 6, the start signal S1 is input from the start signal output terminal 11b of the acceleration sensor 11 to the signal input terminal 13c of the switch circuit 13. The switch circuit 13 is turned on. After the switch circuit 13 is turned on, the main control unit 20 is supplied with the power supply voltage V1, and the microcomputer 21 starts operating. The subsequent operation of the power supply control unit 10 is the same as that of the power supply starting system 100. After the switch circuit 13 is turned on, the power supply voltage V1 is supplied to the measurement circuit 37 and the wireless communication unit 77, and the main control unit 20 is controlled to perform various measurement and wireless communication of the measurement circuit 37. Communication between the department 77 and the outside. Next, the measurement and communication are performed until the end of the life of the primary battery 41. In this case, the power activation system 110 can easily set the device in the vicinity of the crater of the volcano, and the labor and time for manually setting the device or manually starting the device can be omitted. [0093] Hereinafter, the effects of the embodiment will be described in more detail. [0094] The power-on system 100 is configured such that the switching circuit 13 is turned on when the predetermined acceleration value G1 or G2 is detected within the predetermined duration T1, and the switching circuit 13 can be prevented from being caused by the daily artificial acceleration. Open. Therefore, the possibility of erroneous activation can be reduced while the device is surely activated. As a result, it is possible to provide a power source starting system that minimizes the power consumption of the primary battery 41 without increasing the cost of the device. Further, since the switch circuit 13 can be turned on only by dropping the device that houses the power source activation system 100 itself, the device can be easily activated. Further, since only the device that houses the power source activation system 100 itself is rotated on a table or the like to turn on the switch circuit 13, the device can be easily activated. Further, since the power supply voltage V1 is supplied to the acceleration sensor 11 until the switching circuit 13 is turned on, the power supply voltage V1 is not supplied to the main control unit 20 and the measurement circuit 30, and the standby state before the device is started can be minimized. Consumption of electricity. Further, since the wireless communication unit 70 is provided, the measurement result obtained by the measurement circuit 30 can be wirelessly transmitted to the outside. Further, since the switch circuit 13 is turned off when communication is not performed after the startup, useless power consumption can be prevented even if the device is erroneously activated. [0100] Also, since it is suitable for use in the core body 90 for the sensor ball, the sensor ball can be used for a long time. [0101] As described above, the power-on starting system of the present invention is configured such that the switching circuit is turned on when the predetermined acceleration value is detected for a predetermined duration, so that the switch can be prevented from being caused by the daily artificial acceleration. The circuit is turned on. Therefore, the possibility of erroneous activation can be reduced while the device is surely activated. As a result, it is possible to provide a power source starting system that minimizes the power consumption of the primary battery without increasing the cost of the device. The present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the invention.
