First, the configuration of the data recording apparatus will be described. FIG. 1 is a perspective view showing an appearance of the data recording apparatus according to the present embodiment. As shown in FIG. 1, the data recording apparatus 1 includes a cylindrical housing 11, and a battery, a sensor, and a memory are built in the housing 11. The housing 11 has a lid 12, and the inside can be made watertight by closing the lid 12. The cylindrical data recording apparatus 1 is used by being fixed to an animal body by a fixing tool such as a belt. Further, by removing the lid 12 from the housing 11, the internal unit housed in the housing 11 can be taken out from the housing 11.

  FIG. 2 is a plan view showing the configuration of the data recording apparatus 1 according to the present embodiment, and FIG. 3 is a side view thereof. 2 and 3 show the configuration of the internal unit 10 taken out from the housing 11. The internal unit 10 accommodated in the housing 11 includes a first module 2 and a second module 3. The first module 2 includes a battery 21 and a memory 22. The battery 21 and the memory 22 are integrally attached on the base, and the first module 2 is configured as one module. More specifically, the base on which the battery 21 is provided and the base on which the memory 22 is provided are strictly different bases, and the memory 22 is erected vertically on the base on which the battery 21 is provided. The base provided with is attached. In addition, although the battery 21 and the memory 22 are provided on each of the different bases as described above, it is usual that the sensor data is recorded on the animal and the recorded data is collected. These bases are not separated from each other in the state of use, and the combination of a plurality of bases is mainly due to design reasons such as miniaturization. That is, it can be said that the plurality of bases included in the first module 2 substantially constitute one base as a whole. In this specification, the module is a component that is treated as a single element when used, such as the first module 2 in which the battery 21 and the memory 22 are substantially mounted on one base. Means.

  The battery 21 is connected to a power supply circuit provided on the board, and is connected to the memory 22 via the power supply circuit. As a result, power can be supplied to the memory 22.

  The memory 22 is a writable data storage medium such as a RAM or a flash memory, and is used for recording output data from a sensor described later.

  Further, the first module 2 is provided with a connection terminal 23 for external power supply and data transfer, and a connection terminal 24 to the second module 3. The connection terminals 23 and 24 are attached to the base of the first module 2, and are connected to the battery 21 and the memory 22 through power lines and signal lines. The battery 21 is a secondary battery, and the connection terminal 23 is connected to an external power source and used for charging the battery 21. In addition, the connection terminal 23 can be connected to an external personal computer or the like, whereby the data stored in the memory 22 can be transferred to the personal computer or the like.

  The second module 3 includes a microcontroller 31, a wireless communication unit 32, an acceleration sensor 33, an angular velocity sensor 34, a geomagnetic sensor 35, a pressure sensor 36, and a connection terminal 37. The microcontroller 31, the wireless communication unit 32, the acceleration sensor 33, the angular velocity sensor 34, the geomagnetic sensor 35, the pressure sensor 36, and the connection terminal 37 are arranged on the base of the second module 3, and are connected to each other by a signal line or the like. Has been.

  The connection terminal 37 can be connected to the connection terminal 24 of the first module 2. By connecting the connection terminal 24 and the connection terminal 37, the first module 2 and the second module 3 are connected to each other. Further, the first module 2 and the second module 3 are separated from each other by separating the connection terminal 24 and the connection terminal 37. Thus, the first module 2 and the second module 3 are detachable from each other. 4 and 5 are a plan view and a side view of the first module 2 and the second module 3 that are separated from each other.

  The connection terminals 24 and 37 are serial bus connectors for data communication. The connection terminals 24 and 37 also include a power terminal, and the power of the battery 21 can be supplied to the second module 3 side. That is, when the first module 2 and the second module 3 are connected, the microcontroller 31, the wireless communication unit 32, the acceleration sensor 33, the angular velocity sensor 34, the geomagnetic sensor 35, and the pressure sensor 36 are respectively connected to the battery 21. To the microcontroller 31, the wireless communication unit 32, the acceleration sensor 33, the angular velocity sensor 34, the geomagnetic sensor 35, and the pressure sensor 36. In addition, when the first module 2 and the second module 3 are connected, the microcontroller 31 and the memory 22 are connected via a signal line, so that the microcontroller 31 can write data to the memory 22. Become.

  The microcontroller 31 is an integrated circuit in which a CPU, a memory, a timer, and an input / output unit are incorporated. The memory of the microcontroller 31 stores a program for operating the sensors 33 to 36 and storing the output data of the sensors 33 to 36 in the memory 22. Further, setting information of the sensors 34 to 36 is stored in the memory of the microcontroller 31. The microcontroller 31 stores the output data of the sensors 33 to 36 in the memory 22 by executing the program according to the setting information.

  The wireless communication unit 32 is a wireless communication interface that conforms to a predetermined wireless communication standard such as IEEE 802.11 or Bluetooth (registered trademark). The wireless communication unit 32 is controlled by the microcontroller 31, and communication with an external personal computer or the like becomes possible. The wireless communication unit 32 is mainly used for setting the sensors 33 to 36. That is, the setting information of the sensors 33 to 36 transmitted from the external personal computer is received by the wireless communication unit 32, and the setting information is stored in the memory in the microcontroller 31 by the microcontroller 31. Thus, the sensors 33 to 36 are set.

  The acceleration sensor 33 is a three-axis acceleration sensor, and can detect accelerations about three axes (XYZ axes) orthogonal to each other. The angular velocity sensor 34 is a three-axis angular velocity sensor, and can detect angular velocities about three reference axes (XYZ axes) orthogonal to each other. The geomagnetic sensor 35 is a triaxial geomagnetic sensor, and can detect geomagnetism for each of three axes (XYZ axes) orthogonal to each other. The pressure sensor 36 can detect the atmospheric pressure or the water pressure applied to the data recording apparatus 1. Each sensor 33-36 outputs a detection value for every predetermined sampling period. The data output at one time includes three acceleration sensors 33 (XYZ axis accelerations), three angular velocity sensors 34 (XYZ axis angular velocities), and three geomagnetic sensors 35 (XYZ axis magnetic fields). ), A total of 10 detection values including one pressure sensor are included.

[2. Operation of data recording apparatus]
Hereinafter, the operation of the data recording apparatus 1 will be described.

  When investigating the activity of an animal using the data recording device 1, an operator wears the data recording device 1 on the animal to be examined using a fixing tool such as a belt. Thus, with the data recording device 1 mounted on an animal, the sensors 33 to 36 are controlled by the microcontroller 31 to detect acceleration in the XYZ axes, angular velocity for each of the XYZ axes, geomagnetism in the XYZ axes, and pressure. The The detection result data is acquired by the microcontroller 31 for each sampling period and stored in the memory 22.

  The operation of the microcontroller 31 at this time will be described in more detail. The microcontroller 31 writes the output data of the sensors 33 to 36 in the memory 22 according to a predetermined format. In this writing format, 12 pieces of data are set as one set. For example, as described above, in the data recording apparatus 1 according to the present embodiment, each of the sensors 33 to 36 outputs 10 pieces of data per time. One set of output data includes 12 channels, and the 10 output data of each of the sensors 33 to 36 correspond to the channels one to one. For example, the first channel is assigned to the X-axis acceleration data of the acceleration sensor 33, and the second channel is assigned to the Y-axis acceleration data. In this way, the first to tenth channels are assigned to the ten output data of the sensors 33 to 36, respectively. Of the 12 channels, the 11th channel and the 12th channel are vacant.

  When the microcontroller 31 acquires the output data from each of the sensors 33 to 36, the microcontroller 31 associates each output data with each channel. Then, the microcontroller 31 writes the output data to the memory 22 in order from the first channel. For example, if one cycle is required for writing the output data of one channel, the output data of the first channel is written to an area (first area) starting from an address in the memory 22 in the first cycle, and the second cycle. Then, the output data of the second channel is written to the area (second area) starting from the next address of the first area of the memory 22, and the output data of the third channel is next to the second area of the memory 22 in the third cycle. It is written in the area starting from the address (third area). By repeating this, one set of output data is written in a series of areas (first area to twelfth area). Here, since the eleventh channel and the twelfth channel are empty channels, null is stored in the eleventh region and the twelfth region.

  When the writing of one set of output data is completed, the next set of output data is written into an empty area of the memory 22 in the same manner as described above. As the microcontroller 31 repeats this operation, the output data of the sensors 33 to 36 is recorded in the memory 22 in time series.

  When collecting the data recorded in the data recording device 1, the operator captures the animal to which the data recording device 1 is attached and removes the data recording device 1 from the animal. Thereafter, the operator removes the lid 12 from the housing 11 of the data recording apparatus 1 and takes out the internal unit 10 in which the first module 2 and the second module 3 are connected to each other from the housing 11. When the operator separates the first module 2 and the second module 3 and continues the animal investigation, another worker connects the first module 2 to the second module 3 that has been used so far. The internal unit 10 is accommodated in the housing 11, the lid 12 is closed, and the data recording device 1 is attached to the animal. Thus, the worker collects the first module 2 and takes the first module 2 back to the research facility or the like.

  Further, when the first module 2 is replaced as described above, the operator can connect the first module having a memory capacity different from that of the first module 2 used so far to the second module 3. It is. That is, according to the data recording apparatus 1 according to the present embodiment, the data recording apparatus 1 can be replaced with a first module having a different memory capacity. Thereby, the operator can use the data recording apparatus 1 by freely replacing the first module having a memory having a necessary capacity according to the length of the investigation period.

  The operator takes the collected first module 2 back to a research facility or the like, and then transfers the data recorded in the first module 2 to a personal computer. In addition, the worker charges the battery 21 of the first module 2 to make it usable again. FIG. 6 is a schematic diagram for explaining a use state when the first module 2 is charged and data is transferred. The first module 2 can be connected to a cable 4 for charging the battery 21 and transferring data in the memory 22. The cable 4 is provided with a connection terminal 41 for connection to the first module 2. The connection terminal 41 is a terminal that is paired with the connection terminal 23 of the first module 2 and is detachable from the connection terminal 23. A cable including a power line and a signal line extends from the connection terminal 41, and a branching portion 42 is connected to the end of the cable. Each of the cable connected to the connection terminal 41 described above, the power cable connected to the power line included in the cable, and the signal cable connected to the signal line included in the cable extend in the branch portion 42. An insertion plug 43 is provided at the tip of the power line cable, so that it can be connected to a power supply outlet. A connection terminal 44 for connecting to the personal computer 5 is provided at the tip of the signal cable.

  When transferring data from the first module 2 to the personal computer 5, the operator connects the connection terminal 44 to a corresponding connection terminal (not shown) provided in the personal computer 5. Thereby, the data recorded in the memory 22 of the first module 2 can be transferred to the personal computer 5 and stored in an external storage device such as a hard disk. As described above, in the memory 22, one set of output data of the sensors 33 to 36 is divided into 12 continuous areas and stored in a plurality of sets. In the personal computer 5, the data transfer program is executed by the CPU, and the data read from the memory 22 is collected for each channel, and 12 types of data are stored in the external storage device. The That is, X-axis acceleration data, Y-axis acceleration data, Z-axis acceleration data, X-axis angular velocity data, Y-axis angular velocity data, Z-axis acceleration data, Y-axis acceleration data, Z-axis acceleration data, Z-axis acceleration data, Z-axis acceleration data, Z-axis acceleration data Each of the angular velocity data of the axis, the geomagnetic data of the X axis, the geomagnetic data of the Y axis, the geomagnetic data of the Z axis, and the pressure data is reconstructed as a time series data and stored in the external storage device. After such data transfer is completed, all data in the memory 22 is deleted in order to make the first module 2 usable again.

  Using the personal computer 5, the worker uses the personal computer 5 to collect information on the living thing (X-axis acceleration data, Y-axis acceleration data, Z-axis acceleration data, X-axis angular velocity data, Y-axis angular data, Analyze and investigate animal movement trajectory, activity environment, etc. from angular velocity data, Z-axis angular velocity data, X-axis geomagnetic data, Y-axis geomagnetic data, Z-axis geomagnetic data, and pressure data).

  When charging the battery 21 of the first module 2, the operator inserts the plug 43 into the power supply port provided in the research facility. Thereby, the battery 21 is charged. The first module 2 in which the charging is completed and the data in the memory 22 is deleted can be used by being connected to the second module 3 again.

  Further, a second module different from the second module 3 can be connected to the first module 2. For example, in addition to an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, and a pressure sensor, a second module on which a temperature sensor is mounted can be connected to the first module 2. As described above, the second module to be replaced has a different configuration from the first module, but includes the same connection terminal as the connection terminal 37, and the above-described data writing format to the memory 22 Data is written to the memory 22 in a common format. For example, in the case of a second module equipped with a temperature sensor in addition to an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, and a pressure sensor, output data of the temperature sensor is assigned to the eleventh channel out of twelve channels. As a result, even if the second module is different, the sensor output data is written in the memory in a common format. Therefore, even when the memory data is transferred to the personal computer and reconfigured, the same procedure as above is used. The sensor time-series output data can be reconstructed.

  Further, the channel assignment of the output data of the sensor can be designated by the operator by setting the sensor by wireless communication. That is, the worker inputs setting information including channel assignment information of sensor output data to a personal computer or the like, transmits the setting information to the data recording device 1 by wireless communication, and writes it in the memory in the microcontroller 31. Thus, channel assignment setting of sensor output data can be performed.

First, the configuration of the data recording apparatus will be described. FIG. 7 is a perspective view showing an appearance of the data recording apparatus according to the present embodiment. As shown in FIG. 7, the data recording device 101 includes a cylindrical housing 110, and a battery, a sensor, and a memory are built in the housing 110. The housing 110 is constituted by a first housing 111 and a second housing 112 and is separable at a central portion in the longitudinal direction.

  FIG. 8 is a plan view showing the configuration of the data recording apparatus 101 according to the present embodiment. FIG. 8 shows a state where the first housing 111 and the second housing 112 are separated from each other. The first module 2 is accommodated in the first housing 111, and the second module 3 is accommodated in the second housing 112. The configurations of the first module 2 and the second module 3 are the same as the configurations of the first module 2 and the second module 3 according to the first embodiment. Description is omitted.

  The first module 2 is fixed inside the first housing 111, and the second module 3 is fixed inside the second housing 112. Further, one end of the first housing 111, that is, a connection end with the second housing 112 is opened, and similarly, one end of the second housing 112, that is, a connection end with the first housing 111 is opened. Thereby, the connection terminal 24 of the first module 2 is exposed from the opening of the first housing 111, and the connection terminal 37 of the second module 3 is exposed from the opening of the second housing 112. In addition, a cylindrical fitting portion 114 having a slightly smaller diameter than the other portions is provided at the connection end of the second housing 112. When connecting the first housing 111 and the second housing 112, the operator fits the fitting portion 114 into the opening of the first housing 111. An annular O-ring 115 made of a rubber elastic body is attached to the outer periphery of the fitting portion 114, and when the fitting portion 114 is fitted to the opening of the first housing 111, The inner surface in the vicinity of the open end and the O-ring 115 are brought into close contact with each other, whereby the housing 110 becomes watertight.

  Further, the end surface of the first housing 111 opposite to the opening end is partially opened, and the connection terminal 23 is provided in the opening. Thus, the connection terminal 41 of the cable 4 can be connected to the connection terminal 23 without taking out the first module 2 from the first housing 111, and the first module 2 can be connected to an external power source or personal computer via the cable 4. Can be connected to. A rubber lid 113 can be attached to and detached from the opening of the connection terminal 23 provided on the end surface of the first housing 111. When the lid 113 is attached to the opening, the opening is sealed by the lid 113, and the end surface of the first housing 111 to which the lid 113 is attached is in a watertight state.

[4. Operation of data recording apparatus]
Hereinafter, the operation of the data recording apparatus 101 will be described.

  When collecting the data recorded in the data recording device 101 attached to the animal, the operator captures the animal attached to the data recording device 101 and removes the data recording device 101 from the animal. Thereafter, the worker separates the first housing 111 and the second housing 112 of the data recording apparatus 101 to separate the first module 2 and the second module 3 from each other. When the worker continues to investigate the animal, the worker connects another first housing 111 to the second housing 112 used so far.

  When connecting the first housing 111 and the second housing 112, the operator connects the first housing 111 and the second housing so that the connection terminal 24 of the first module 2 and the connection terminal 37 of the second module 3 are connected. The fitting portion 114 is inserted into the opening of the first housing 111 while aligning the two housings 112. Thereby, the first housing 111 and the second housing 112 are fitted, and the connection terminals 24 and 37 are connected to each other. In this way, the operator replaces the first module 2 of the data recording apparatus 101. The data recording device 101 in which the first module 2 has been replaced is attached to an animal. Further, the operator takes the collected first module 2 back to the research facility or the like.

  Since other operations of the data recording apparatus 101 according to the present embodiment are the same as the operations of the data recording apparatus 1 according to the first embodiment, the description thereof is omitted.

  As described above, according to the data recording apparatuses 1 and 101 according to the first and second embodiments, the first module 2 on which the battery 21 and the memory 22 are mounted is replaced with the second module 3 on which the sensors 33 to 36 are mounted. In order to collect data from the data recording devices 1 and 101 attached to the animal, the operator can transfer data to a personal computer or the like at the site where the data recording devices 1 and 101 are removed from the animal. The first module 2 may be removed from the data recording apparatuses 1 and 101 without transferring the data of the recording apparatuses 1 and 101. After bringing the first module 2 back to the research facility or the like, the worker can transfer the data to a personal computer or the like. When the data recording of the animal from which the data recording devices 1 and 101 are removed is continuously performed, the operator can replace the first module 2 on the spot where the data recording devices 1 and 101 are removed from the animals. Good. As described above, according to the data recording apparatuses 1 and 101 according to the first and second embodiments, it becomes possible to collect data more easily than in the past.

  Further, as described above, when one second module 3 is continuously used even after replacement of the first module 2, it is not necessary to calibrate the sensors 33 to 36. For this reason, compared with exchanging all the data recording devices, it is possible to greatly reduce the burden and time of the operator for the replacement work of the data recording devices.

  In addition, since the battery 21 is a secondary battery and the connection terminal 23 for charging and data transfer is provided in the first module 2, the operator can charge the battery 21 and store it in the memory 22 via the connection terminal 23. The recorded data can be transferred.

  Since the setting information of the sensors 33 to 36 is stored in the internal memory of the microcontroller 31 of the second module 3, the setting information before the replacement of the first module 2 even after the first module 2 is replaced. Is maintained. Therefore, the operator can use the data recording devices 1 and 101 in which the first module 2 has been replaced in the same manner as before the replacement of the first module 2.

  Further, the second module 3 is provided with a wireless communication unit 32, and the wireless communication unit 32 receives setting information of the sensors 33 to 36 from the outside, and stores the received setting information in the internal memory of the microcontroller 31. Therefore, the operator can easily set the sensors 33 to 36.

  Moreover, since it was set as the structure which accommodates the 1st module 2 and the 2nd module 3 in the housings 11 and 110 which can be sealed, the 1st module 2 and the 2nd module 3 are protected by the housings 11 and 110, and an operator is various. The data recording devices 1 and 101 can be used in an environment.

  In addition, according to the data recording apparatus 101 according to the second embodiment, when the first housing 111 and the second housing 112 are connected to each other, the first module 2 and the second module 3 are connected to each other. Therefore, the operator can connect the first module 2 and the second module 3 only by connecting the first housing 111 and the second housing 112 to each other. The entire module 3 can be accommodated in the housing 110.

It is not limited to this. The connection terminal for connection to the second module 3 can also be used for charging and data transfer to an external personal computer, and the connection terminal 23 can be omitted. In particular, when the connection terminal 23 is removed from the data recording apparatus 101 according to the second embodiment, there is no need to provide an opening for the connection terminal 23 on the end surface of the first housing 111, and the degree of sealing of this portion is increased. Further improvement can be achieved.
