2. Basic Configuration of Data Recording System Having a plurality of Data Recording Devices FIG. 2 shows a basic configuration diagram of a data recording system having a plurality of data recording devices. A data recording apparatus 10 shown in FIG. 1 is attached to each measurement site of a plurality of measurement sites P1 to P7 of the measurement object 1. The data recording device 10 attached to each measurement site P1 to P7 has a unique ID. For convenience of the following description, ID data of the data recording apparatus 10 attached to the measurement position Pi (i = 1 to 7) is referred to as IDi, measurement data is referred to as MEi, and position identification data is referred to as POi. In the figure, only seven positions P1 to P7 are shown as measurement parts, but it is needless to say that the measurement parts are not limited thereto.

  Focusing on the measurement site P1, a plurality of sensors 12 are provided for the data recording device 10 that operates with the power from the battery. A measurement signal from each sensor 12 is transmitted to the data recording device 10. The measurement signal from each sensor 12 is converted into measurement data in the data recording device 10 and stored in the memory 10c. The same applies to other measurement sites. Moreover, although not shown in figure, the identification signal transmission circuit 16 is provided in the vicinity of each data recording device 10 in each measurement site | part P1-P7.

  A transmission / reception device 20 and a host computer 30 are provided for the measurement object 1. In the figure, the transmission / reception device 20 and the host computer 30 are each single, but a plurality of them may be provided. The host computer 30 wirelessly transmits a trigger signal to all the data recording devices 10 attached to the measurement sites P1 to P7 via the transmission / reception device 20. Further, the host computer 30 receives the measurement data and identification data at the measurement sites P1 to P7 transmitted from each data recording device 10 via the transmission / reception device 20, and stores these data in an internal or external storage device. Store.

3. Basic Operation In the configuration shown in FIG. 2, the host computer 30 outputs a measurement start signal to the transmission / reception device 20 as a trigger signal. The transmission / reception device 20 receives the measurement start signal from the host computer 30 and transmits the measurement start signal wirelessly to all the data recording devices 10 attached to the measurement parts P1 to P7.

  Hereinafter, since the operation of all the data recording devices 10 is the same, the data recording device 10 attached to the measurement site P1 will be described as an example. This description is similarly applied to all the other data recording apparatuses 10.

  The data transmitting / receiving device 10e of the data recording device 10 attached to the measurement site P1 receives the measurement start signal and outputs it to the CPU 10b. In response to receiving the measurement start signal, the CPU 10b receives the measurement signal from the sensor 12, and stores it in the memory 10c as measurement data ME1. As shown in FIG. 2, when there are a plurality of sensors 12 for the data recording apparatus 10, measurement data ME1 is stored in the memory 10c as a set of measurement data of each sensor. Assuming that the sensor 12 is composed of a sensor a, a sensor b, and a sensor c, and the measurement data of each sensor is ME (a), ME (b), and ME (c), the measurement data ME1 is ME (a). , ME (b), and ME (c). Further, the CPU 10b stores the position identification data PO1 from the identification signal receiving circuit 10d in the memory 10c. Then, the CPU 10b outputs ID1, which is unique ID data, measurement data ME1, and position identification data PO1, as a set to the data transmission / reception circuit 10e. The data transmission / reception circuit 10e receives ID1, measurement data ME1, and position identification data PO1 from the CPU 10b, and transmits them to the transmission / reception device 20 wirelessly. Since all the data recording apparatuses 10 execute the above-described processing in response to the measurement start signal, the measurement data MEi acquired in all the data recording apparatuses 10 are synchronized.

  The transmission / reception device 20 receives IDi, measurement data MEi, and position identification data POi wirelessly transmitted from each data recording device 10 and outputs them to the host computer 30. The host computer 30 stores IDi, measurement data MEi, and position identification data POi as a set in a storage device. Therefore, the set data of (ID1, ME1, PO1), (ID2, ME2, PO2),... (ID7, ME7, PO7) is stored in the storage device.

  Note that the data recording apparatus 10 may not start measurement immediately after receiving a measurement start signal as a trigger signal, but may start measurement after a predetermined time has elapsed after receiving the measurement start signal. That is, the CPU 10b of the data recording device 10 starts the built-in timer when receiving the measurement start signal, and starts measurement at a timing when a predetermined time has elapsed. Even in this case, if the predetermined time is unified with a constant value in all the data recording devices 10, synchronization of measurement timing is established. Moreover, although it is preferable that the transmission timing of the measurement data MEi of all the data recording apparatuses 10 to the host computer 30 is synchronized, it is not always necessary to synchronize. For example, all the data recording apparatuses 10 transmit at random timing or sequentially transmit. In short, the measurement timing of the measurement data MEi only needs to be synchronized, and the transmission timing of the measurement data MEi may be asynchronous.

The host computer 30 stores the set data received from all the data recording devices 10 in the storage device, and monitors the measurement object 1 using these set data. Since the set data includes ID data IDi, measurement data MEi, and position identification data POi, the host computer 30 can easily associate the measurement position Pi with the measurement data MEi, and the measurement data at a certain measurement position Pi. The state at the measurement site Pi can be monitored by immediately specifying the MEi. The host computer 30 creates a table associating IDi with POi and stores it in a built-in or external memory. The table is conceptually as follows.
ID1-PO1 (P1)
ID2-PO2 (P2)
ID3-PO3 (P3)
...
ID7-PO7 (P7)

  Thereafter, by referring to this table, the measurement site can be specified only from IDi, and the measurement data Mi at each measurement site can be sequentially stored in the memory and monitored.

4). Application to Collision Test Dummy The data recording system in this embodiment can be applied to a collision test dummy. In this case, the measurement target 1 in FIG. 2 is a collision test dummy, and the measurement sites P1 to P7 are dummy measurement sites, for example, the head, arms, chest, and legs.

  FIG. 3 shows the configuration of the data recording system when applied to a collision test dummy. The crash test dummy 2 is a mannequin that imitates the shape of a person and is mounted on a vehicle such as an automobile. The vehicle on which the collision test dummy 2 is placed is given a pseudo collision by, for example, colliding with an obstacle at a constant speed, and causes an inertial load on the collision test dummy 2. A sensor is attached to each part of the collision test dummy 2 to detect the inertial load generated in each part, and the detected inertial load is analyzed to evaluate the influence on the vehicle occupant.

  As shown in FIG. 3, the collision test dummy 2 is roughly divided into a head, a trunk, a right arm, a left arm, a right leg, and a left leg. The data recording device 10 and the sensor 12 are respectively attached to these portions of the collision test dummy 2. For example, a data recording device 10, a battery 14 that is a power source of the data recording device 10, and a sensor 12 that detects an inertial load in the head are attached to the head. The sensor 12 may be either a single sensor or a plurality of sensors (a plurality of cases are shown in the figure). The type of the sensor 12 is an acceleration sensor, a pressure sensor, or the like. In addition, a data recording device 10, a battery 14, and a sensor 12 for detecting an inertial load in the left arm are attached to the left arm (a single case is shown in the figure).

  In such a configuration, the host computer 30 outputs a measurement start signal to the transmission / reception device 20 as a trigger signal. The transmission / reception device 20 receives the measurement start signal from the host computer 30 and wirelessly transmits the measurement start signal to all the data recording devices 10 attached to each part of the collision test dummy 2.

  The data transmission / reception device 10e of the data recording device 10 attached to the head receives the measurement start signal and outputs it to the CPU 10b. In response to receiving the measurement start signal, the CPU 10b receives the measurement signal from the head sensor 12, and stores it in the memory 10c as measurement data ME. Further, the CPU 10b stores head identification data PO as position identification data from the identification signal receiving circuit 10d in the memory 10c. Then, the CPU 10b outputs the ID, which is unique ID data, the measurement data ME, and the head identification data PO as a set to the data transmission / reception circuit 10e. The data transmission / reception circuit 10e receives the ID, measurement data ME, and head identification data PO from the CPU 10b, and transmits them to the transmission / reception device 20 wirelessly. Further, the data transmission / reception device 10e of the data recording device 10 attached to the trunk receives the measurement start signal and outputs it to the CPU 10b. In response to receiving the measurement start signal, the CPU 10b receives the measurement signal from the body sensor 12 and stores it in the memory 10c as measurement data ME. Further, the CPU 10b stores the body part identification data PO from the identification signal receiving circuit 10d in the memory 10c. Then, the CPU 10b outputs the ID, which is unique ID data, the measurement data ME, and the body identification data PO as a set to the data transmission / reception circuit 10e. The data transmission / reception circuit 10e receives the ID, the measurement data ME, and the body identification data PO from the CPU 10b, and transmits them to the transmission / reception device 20 wirelessly. The same applies to the data recording devices 10 of other parts. In all the data recording devices 10, the above processing is executed in response to the measurement start signal.

  The transmission / reception device 20 receives the ID, measurement data ME, and position (any one of the head, trunk, right arm, left arm, right leg, and left leg) identification data PO transmitted wirelessly from each data recording device 10. Is output to the host computer 30. The host computer 30 stores the ID, measurement data ME, and position identification data PO as a set in the storage device, and evaluates the influence of the collision on the occupant based on the measurement data ME in each part.

In the above description, as shown in FIG. 1, it is assumed that an identification signal transmission circuit 16 is attached in the vicinity of the data recording apparatus 1 and a position identification signal is transmitted from the identification signal transmission circuit 16 to the data recording apparatus 10. However, the identification signal transmission circuit 16 is not necessarily provided. In the case where the identification signal transmission circuit 16 is not provided, there are the following methods for associating the data recording device 10 (or the unique ID of the data recording device) attached to each part with the measurement part.
(1) The measurement user manually performs the operation of associating the ID of the data recording device 10 installed at each measurement site with the measurement site on the host computer 30.
(2) The measurement user gives a signal to the data recording device 10 installed at each measurement site, transmits the signal and the ID of the data recording device 10 to the host computer 30, and uses the information to record the data recording device 10 A table is created by associating the IDs and measurement sites.
(3) The measurement user irradiates light to the optical sensor connected to the data recording device 10 installed in each measurement site, and transmits the signal and the ID of the data recording device 10 to the host computer 30 to obtain the information. Is used to create a table by associating the ID of the data recording device 10 with the measurement site.

  The method (1) is the simplest method, but as the number of measurement sites increases, the measurement user association work becomes enormous and complicated. Therefore, the methods (2) and (3) will be described in order below.

  FIG. 4 schematically shows an example of a method for giving a signal to the data recording apparatus 10 in the method (2). The data recording device 10, the sensor 12, and the battery 14 are attached to the measurement site, and an acceleration sensor (or pressure sensor) is provided as the sensor 12. When the host computer 30 associates the ID of the data recording device 10 with the measurement site, the measurement user gives an impact to the acceleration sensor by some means. In addition, although the hammer is illustrated as a means to give an impact in the figure, you may give an impact using a part (for example, finger or hand) of the measurement user's body. The acceleration sensor detects this impact and outputs a detection signal to the data recording device 10. The data recording device 10 stores a detection signal from the acceleration sensor as measurement data in the memory 10c, and wirelessly transmits a unique ID and measurement data to the host computer 30. The host computer 30 associates the measurement site that gave the impact with the ID of the data recording device 10 from these IDs and measurement data. For example, it is assumed that the ID of the data recording device 10 installed on the head of the crash test dummy is ID1. The measurement user inputs a condition for giving a shock to the head to the host computer 30, and then gives a shock to the acceleration sensor of the head by some means. Then, in response to the trigger signal from the host computer 30, ID 1 and measurement data, which are the IDs, are output from the head data recording device 10, while other data installed in other parts of the crash test dummy Since significant measurement data is not output from the data recording apparatus 10, the host computer 30 can create a table in association with the data recording apparatus 10 identified by ID1 being installed on the head.

  The sensor 12 may be a pressure sensor instead of an acceleration sensor. In this case, the measurement user can apply significant pressure to the pressure sensor of the data recording device 10 to be associated with the measurement site by some means (such as pressing with a finger) to output significant measurement data from the data recording device 10. That's fine.

  FIG. 5 schematically shows a method of associating the data recording apparatus 10 with the measurement site in the method (3). A data recording device 10, a sensor 12, and a battery 14 are attached to the measurement site, and an optical sensor 13 is provided as a part of the sensor 12 or in addition to the sensor 12 (in the figure, as a sensor separate from the sensor 12). Show). When the host computer 30 associates the ID of the data recording device 10 with the measurement site, the measurement user irradiates the light sensor 13 with some means. The optical sensor 13 detects this light irradiation and outputs a detection signal to the data recording device 10. The data recording device 10 stores the detection signal from the optical sensor 13 in the memory 10 c as measurement data, and wirelessly transmits a unique ID and measurement data to the host computer 30. The host computer 30 associates the measurement site irradiated with light and the ID of the data recording device 10 from these IDs and measurement data. For example, it is assumed that the ID of the data recording device 10 installed on the head of the crash test dummy is ID1. The measurement user inputs a condition for irradiating the head with light to the host computer 30 and then irradiates the light sensor 13 on the head with light. Then, in response to the trigger signal from the host computer 30, ID 1 and measurement data, which are the IDs, are output from the head data recording device 10, while other data installed in other parts of the crash test dummy Since significant measurement data is not output from the data recording apparatus 10, the host computer 30 can associate that the data recording apparatus 10 specified by ID1 is installed on the head.

  Thus, even if the identification signal transmission circuit 16 for specifying the measurement site is not installed as shown in FIG. 1, the sensor 12 or the optical sensor 13 installed in the measurement site can be used to perform measurement on the host computer 30 side. It is possible to associate the part and the ID of the data recording device 10 installed in the measurement part, and create a table indicating the association.

  In FIG. 1, an identification signal generating circuit 16 for transmitting a position identification signal is used. However, as shown in FIG. 6, this is composed of an ID tag (IC chip) 17 provided in the vicinity of the data recording device 10. Can do. Position information is stored in the ID tag 17, and the position information is transmitted wirelessly. The data recording device 10 receives the position information from the ID tag 17.

  Hereinafter, these methods will be described in more detail by taking a collision test dummy as an example. Since the collision test dummy is normally fixed and stored in a storage frame dedicated to the dummy, in this embodiment, the measurement part and the ID of the data recording apparatus 10 are associated with each other by paying attention to the dummy storage frame.

  FIG. 7 shows an application example of the method of installing the ID tag 17 as shown in FIG. 6 in the vicinity of the data recording device 10 to a collision test dummy. FIG. 7A is a front view, and FIG. 7B is a side view (right side view). The crash test dummy 2 is fixed to the dummy storage frame 3 in a sitting posture. The dummy storage frame 3 has a substantially seat shape, and includes a leg frame, a seating surface frame, and a back frame. The dummy storage frame 3 fixes the crash test dummy 2 at the leg, waist, chest and the like. Of course, the fixing location is arbitrary and may be fixed at other locations.

  In the collision test dummy 2, as shown in FIG. 3, a data recording device 10 is installed at each measurement site. In addition, although the sensor 12 and the battery 14 are also installed in the vicinity of each data recording apparatus 10, illustration is abbreviate | omitted in FIG. 7 for convenience of explanation. The data recording device 10 is installed at the head, right arm, left arm, chest, shin, foot, and the like. The dummy storage frame 3 is provided with an identification signal transmission circuit 16 or an ID tag 17 in the vicinity of the data recording device 10. In the figure, the case where the ID tag 17 is installed in the dummy storage frame 3 is shown. The ID tag 17 is installed in the vicinity of each data recording device 10 so as to correspond to the data recording device 10 on a one-to-one basis. That is, the data recording device 10 corresponding to the ID tag 17 is installed in the radio wave reachable range of the ID tag 17. For example, the ID tags 17 are installed on the left and right frames facing the right arm portion and the left arm portion of the collision test dummy 2 of the dummy storage frame 3. In addition, ID tags 17 are installed on the left and right frames of the dummy storage frame 3 facing the shin portion of the collision test dummy 2. An ID tag 17 is installed on the frame of the dummy storage frame 3 that faces the foot of the collision test dummy 2.

  The data recording device 10 installed at each measurement site of the collision test dummy 2 receives the position information (position identification data) transmitted from the ID tag 17 installed in the dummy storage frame 3 correspondingly. Store in the memory 10c. Then, in response to a trigger signal from the host computer 30, it transmits its own ID, measurement data, and position identification data to the host computer 30. The host computer 30 creates a table by associating each measurement site of the collision test dummy 2 with each ID of the data recording device 10 using these data sets.

  Although the ID tag 17 may be installed in all of the plurality of data recording devices 10, the ID tag 17 may not be installed in any of the data recording devices 10. The reason is that, when the ID tag 17 is not installed in any one of the data recording devices 10, the measurement site of the data recording device 10 can be specified in reverse. For example, when the ID tag 17 is not installed in the head data recording device 10 and the ID tag 17 is installed in other data recording devices 10, each data recording device 10 (ID, measurement data, position A set of (identification data) is transmitted, but since only the set of (ID, measurement data) is transmitted from the head data recording device 10, (no position identification data) = (position identification data of the head) And can be uniquely identified.

  FIG. 8 shows an application example of the method of installing the optical sensor 13 as shown in FIG. 5 in the vicinity of the data recording apparatus 10 to a collision test dummy. FIG. 8A is a front view, and FIG. 8B is a side view (right side view). The crash test dummy 2 is fixed to the dummy storage frame 3 in a sitting posture. The dummy storage frame 3 has a substantially seat shape, and includes a leg frame, a seating surface frame, and a back frame. The dummy storage frame 3 fixes the crash test dummy 2 at the leg, waist, chest and the like.

  In the collision test dummy 2, a data recording device 10 is installed at each measurement site. The data recording device 10 is installed at the head, right arm, left arm, chest, shin, foot, and the like. Then, with the collision test dummy 2 fixed to the dummy storage frame 3, the optical scanning device 4 is disposed in front of the collision test dummy 2, and the collision test dummy 2 is irradiated with light in a predetermined order. The optical scanning device 4 includes a light irradiation unit 4a, and the light irradiation unit 4a emits light while moving in the x direction and the y direction in the drawing. FIG. 8A shows an irradiation locus, that is, a scan range when the light irradiation unit 4a emits light while moving. The optical scanning device 4 is driven based on a scan command signal from the host computer 30, and the scan position (x, y) in the optical scanning device 4 is determined by the host computer 30.

  Since the collision test dummy 2 is fixed to the dummy storage frame 3, and the relative positional relationship between the optical scanning device 4 and the collision test dummy 2 or the dummy storage frame 3 is set in advance, The correspondence between (x, y) and each measurement site of the collision test dummy 2 can be uniquely determined. When the host computer 30 drives the optical scanning device 4 to scan the collision test dummy 2, a detection signal is output to the data recording device 10 from the optical sensor 17 at the position irradiated with light, and the data recording device 10 transmits the measurement data together with its own ID to the host computer 30. The host computer 30 can associate the ID of the data recording apparatus 10 and the measurement site from the scan position (x, y) and the received set data (ID, measurement data). For example, it is assumed that the scan coordinate of the head is (x1, y1), and the ID of the data recording device 10 installed on the head is ID1. Assume that the host computer 30 instructs the optical scanning device 4 to scan the collision test dummy 2 and receives (ID1, measurement data) at the scan position (x1, y1). Then, the host computer 30 can associate that the data recording device 10 identified by ID1 is the data recording device 10 installed in the measurement site identified by the scan position (x1, y1), that is, the head. .

  FIG. 9 shows an application example of the method of installing an acceleration sensor (or pressure sensor) as shown in FIG. 4 in the vicinity of the data recording apparatus 10 to a collision test dummy. FIG. 9A shows a front view, and FIG. 9B shows a display 30 a of the host computer 30 or the handheld terminal 31 connected to the host computer 30. The crash test dummy 2 is fixed to the dummy storage frame 3 in a sitting posture. The dummy storage frame 3 has a substantially seat shape, and includes a leg frame, a seating surface frame, and a back frame. The dummy storage frame 3 fixes the crash test dummy 2 at the leg, waist, chest and the like.

  In the collision test dummy 2, a data recording device 10 is installed at each measurement site. In the vicinity of the data recording apparatus 10, an acceleration sensor is installed as the sensor 12. The data recording device 10 is installed at the head, right arm, left arm, chest, shin, foot, and the like. Then, the host computer 30 or the handheld terminal displays a schematic diagram of the collision test dummy 2 on the display 30a, and the measurement user displays and commands a portion to which an impact should be applied by some means (for example, a hammer or the like). In the figure, the display 30a indicates that an impact should be applied to the left arm portion of the collision test dummy 2. At the same time, the host computer 30 transmits a display control signal to the dummy storage frame 3. A display device 18 is installed in each part of the dummy storage frame 3, and a specific display device 18 is controlled to be turned on in response to a display control signal from the host computer 30. The part which should give the impact displayed on the display 30a respond | corresponds with the display apparatus 18 by which lighting control is carried out among the display apparatuses 18. FIG. Therefore, if the left arm portion is a portion to be impacted, the display device 18 corresponding to the left arm portion of the display device 18 is controlled to be lit.

  The measurement user installs at each measurement site of the collision test dummy 2 according to the information on the site to which an impact is to be displayed displayed on the display 30a or the display device 18 whose lighting is controlled among the display devices 18 of the dummy storage frame 3. Among the obtained acceleration sensors, an impact is given to a specific acceleration sensor. The acceleration sensor applied with the impact detects the impact and outputs it to the data recording device 10. The data recording device 10 transmits its own ID and measurement data to the host computer 30. The host computer 30 can associate the ID of the data recording device 10 and the measurement position using the data received from the data recording device 10 and the display device 18 that is displayed on the display 30a or the lighting control.

  In any of the methods shown in FIGS. 7 to 9, each measurement portion of the collision test dummy 2 and the data recording device 10 are utilized by utilizing the fact that the collision test dummy 2 is fixed and stored in the dummy storage frame 3. Can be easily and reliably associated (associated) with the ID. When the host computer 30 associates the measurement position with the ID, the host computer 30 stores the association data in a built-in or external memory as a table. In the subsequent processing, when data is received from the data recording device 10 of each measurement part, the ID included in the data is collated with the table, the measurement data in each measurement part is specified and sequentially recorded in the memory. To go.

  In any of the methods of FIGS. 7 to 9, since the measurement site and the ID of the data recording device 10 can be associated with each other while the crash test dummy 2 is fixed to the dummy storage frame 3, the crash test is actually performed. In the adjustment process before the dummy 2 is mounted on the vehicle and the collision test is performed, there is an advantage that the association can be performed at the same time. That is, before the collision test, it is necessary to confirm whether or not each data recording apparatus 10 operates normally. In this confirmation work, each data recording apparatus 10 is operated by the method shown in FIGS. In this case, a table may be created by associating the measurement site with the ID. In particular, in the methods of FIGS. 8 and 9, it is possible to create a table simultaneously with the operation of confirming whether the optical sensor 13 and the acceleration sensor (or pressure sensor) operate normally.

5. Application to Other Systems Although the case where the data recording system of the present embodiment is applied to the crash test dummy 2 has been described above, the system of the present embodiment can also be applied to other applications.

  As an example, FIG. 10 shows an example of application to a package monitoring system that monitors the status of each package when a plurality of packages are loaded in a warehouse or truck bed. A data recording device 10 is installed in each of a plurality of packages 5 that are carried into a warehouse or mounted on a truck bed. A sensor 12 is installed in the vicinity of the data recording device 10 and a battery 14 as a power source is also installed, but these are omitted from the drawing for convenience of explanation. Each sensor 12 detects acceleration, pressure, temperature, or humidity, and outputs it to the data recording apparatus 10 as a detection signal. In response to the trigger signal from the host computer 30, the data recording device 10 transmits its own ID and measurement data to the host computer 30.

  Further, the state of the luggage 5 can change depending on the position in the warehouse or the loading platform. Therefore, it is preferable to specify the position of each luggage 5. FIG. 11 further shows a system for specifying the position of each package 5. A radio wave transmitter 6 is installed at a predetermined position of a warehouse or a loading platform, for example, at each corner. The data recording device 10 of the package 5 receives the radio wave from each radio wave transmitter 6 and detects the position of the data recording device 10, that is, the position of the package 5 from the ratio of the received intensity. The data recording apparatus 10 transmits its own ID, measurement data, and position data to the host computer 30 as set data.

  The data recording device 10 simply detects the ratio of the reception intensity of each radio wave transmitter 6 and transmits it to the host computer 30, and the host computer 30 specifies the position of the data recording apparatus 10 from the reception intensity ratio. Good.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment, A various deformation | transformation is possible.

  For example, in the above-described embodiment, an impact is applied to the acceleration sensor (or pressure sensor) or light is applied to the optical sensor, but any other (but can be applied locally). Physical or optical stimuli can be used.
