The secondary battery 161 is connected to the charge / discharge control circuit 162. The charge / discharge control circuit 162 controls charge / discharge of the secondary battery 161.

  The vibration generator 163 generates electric power according to the vibration.

  3 is a perspective view of the vibration generator 163, FIG. 4 is an exploded perspective view of the vibration generator 163, and FIG. 5 is a cross-sectional view of the vibration generator 163.

  The vibration power generator 163 includes a fixed portion 171, a movable portion 172, a support 173, a spring 174, and the like.

  The fixed part 171 includes a permanent magnet 181, a core part 182, and a magnetic piece 183 and constitutes a magnetic circuit.

  The permanent magnet 181 has a cylindrical shape and is magnetized in the axial direction and the arrow A direction. The permanent magnet 181 is fixed to the core portion 182.

  The core portion 182 is configured by molding a magnetic material such as ferrite into a bottomed cylindrical shape. The lower end of the permanent magnet 181 is fixed to the center of the bottom surface of the core portion 182. The magnetic piece 183 is made of a magnetic material such as ferrite and is fixed to the upper end portion of the permanent magnet 181.

  The magnetic flux emitted from the upper end of the permanent magnet 181 is supplied to the magnetic piece 183. The magnetic flux supplied to the magnetic piece 183 is supplied to the peripheral portion of the opening portion of the core portion 182 through the gap G formed between the magnetic piece 183 and the peripheral portion of the opening portion of the core portion 182.

  The magnetic flux supplied to the core part 182 passes through the side part of the core part 182 and is supplied to the bottom part of the core part 182. The magnetic flux supplied to the bottom part of the core part 182 is supplied to the lower end part of the permanent magnet 181. Thus, a closed magnetic circuit is configured.

  The movable portion 172 includes a holder 191, a coil 192, and a weight 193, and is inserted into the core portion 182 from the gap G of the fixed portion 171.

  As described above, when the movable part 172 swings with respect to the fixed part 171 due to the vibration of the mounting target, the electromotive force is generated in the coil 192 as described above to generate power.

  Note that the configuration of the vibration generator 163 is not limited to the above-described configuration, and may be any configuration that can generate power by vibration.

  The voltage generated by the vibration generator 163 is supplied to the rectifying / smoothing circuit 164.

  The input unit 123 includes a switch and is connected to the processing unit 121. The input unit 123 is a device that inputs an instruction to the processing unit 121 to start measurement, end measurement, and the like.

  Next, processing of the processing unit 121 will be described.

  FIG. 6 shows a processing flowchart of the processing unit 121.

  When the trigger pulse is supplied from the trigger circuit 115 in step S1-1, the processing unit 121 resets the internal timer of the processing unit 121 in step S1-2. The built-in timer is timed up when measuring a certain time T0.

  Next, in step S1-3, the processing unit 121 reads vibration data from the A / D converter 113, position data from the position detection unit 118, time data from the time detection unit 119, and environmental data from the environment detection unit 120. The vibration data, position data, time data, and environment data read in S1-5 are combined and stored in the storage device 117.

  In step S1-5, the processing unit 121 determines whether the time measured by the timer has expired. When the time measured by the timer is up in step S1-5, the processing unit 121 reads the vibration data from the A / D converter 113 and the position data from the position detection unit 118 in step S1-6. Reading, reading of time data from the time detection unit 119, and reading of environment data from the environment detection unit 120 are stopped, and the data stored in the storage device 117 in step S1-7 is traced back by a predetermined time T1 from the current time. to erase.

  The predetermined time T1 may be the same as the predetermined time T0, but is stored in the storage device 117 when the trigger pulse is generated by setting the predetermined time T1 to a value smaller than the predetermined time T0 from the reset of the timer to the time-up. The erased data can be prevented from being erased.

  On the other hand, when the time measured by the timer has not expired in step S1-5, the processing unit 121 determines in step S1-8 whether a trigger pulse is supplied from the trigger circuit 115.

  If the trigger pulse is not supplied from the trigger circuit 115 in step S1-8, the processing unit 121 returns to step S1-3 to continue the process, and the trigger pulse is supplied from the trigger circuit 115 in step S1-8. Then, the process returns to step S1-2 to continue the processing.

  In addition, the process part 121 continues the process of step S1-1-S1-8 until completion | finish of a measurement is instruct | indicated in step S1-9. The end of measurement is instructed by operating the input unit 123, for example.

  Next, the operation of this embodiment will be described with reference to the drawings.

  FIG. 7 shows an operation explanatory diagram of one embodiment of the present invention. 7A shows the waveform of the vibration detection signal, FIG. 7B shows the full-wave rectification waveform of the vibration detection signal, and FIG. 7C shows the waveform of the recording signal.

  When the full-wave rectified waveform of the vibration detection signal shown in FIG. 7B exceeds the trigger level Vsh at time t 0, a trigger pulse is supplied from the trigger circuit 115 to the processing unit 121. When the trigger pulse is supplied from the trigger circuit 115, the processing unit 121 starts storing digital data in the storage device 117 according to the vibration detection signal from the A / D converter 113. When the vibration detection signal falls below the trigger level at time t1 and the trigger pulse is not supplied from the trigger circuit 115 to the processing unit 121, and after a predetermined time T0 has elapsed at time t2, the processing unit 121 performs A / D conversion. The storage of the digital data corresponding to the vibration detection signal from the storage device 113 is stopped, and the digital data stored in the storage device 117 is deleted retroactively for a predetermined time T1. In FIG. 7, T0 = T1 is set in order to simplify the description.

  Next, when the vibration detection signal again exceeds the trigger level at time t 3, a trigger pulse is supplied from the trigger circuit 115 to the processing unit 121. When the trigger pulse is supplied from the trigger circuit 115, the processing unit 121 again starts storing digital data in the storage device 117 according to the vibration detection signal from the A / D converter 113. When the vibration detection signal falls below the trigger level at time t4 and the trigger pulse is not supplied from the trigger circuit 115 to the processing unit 121, the processing unit 121 performs A / D conversion after a predetermined time T0 has elapsed at time t5. The storage of the digital data corresponding to the vibration detection signal from the storage device 113 is stopped, and the digital data stored in the storage device 117 is deleted retroactively for a predetermined time T1 = T0.

  Thus, the data from time t1 to time t3 and from time t4 to time t5 shown in FIG. 7A is not stored in the storage device 117. Therefore, as shown in FIG. 7C, the vibration detection signal stored in the storage device 117 has a waveform from which the times t1 to t3 and t4 to t6 with almost no vibration are deleted.

  Thus, according to the present embodiment, since a vibration signal that does not contribute to the vibration analysis and does not contribute to the trigger level vsh is not stored, it is possible to prevent the storage capacity of the storage device 117 from being wasted.

  Note that the vibration recording apparatus 100 according to the present embodiment is mounted on, for example, a cargo transportation vehicle. The vibration generated at the time of cargo transportation is stored in the storage device 117 and analyzed to analyze the influence of the vibration at the time of transportation on the cargo. At this time, in the case of freight transportation, there are relatively many cases where the vehicle is stopped. There is no vibration in the situation where the vehicle is stopped and no vibration occurs, for example, the driver's rest time in a truck, etc., or the stop time at a station in a tracked vehicle, etc. Even if the vibration is stored in the storage device 117 in a state where the slight vibration is generated, it is not useful for the analysis.

  At this time, the capacity of the storage device 117 can be reduced by not storing in the storage device 117 vibration signals that do not contribute to the vibration analysis and do not contribute to the trigger level vsh as in this embodiment. Thereby, the vibration recording apparatus 100 can be provided at low cost. Note that the storage device 117 is set as appropriate according to the conveyance status and the like. At this time, by using the data storage method of this embodiment, it is possible to cope with the minimum necessary storage capacity. Further, power consumption can be suppressed, and the capacity of a battery or the like can be reduced. Therefore, the apparatus can be configured at low cost.

  In addition, in a freight transportation vehicle traveling on a public road, the times T0 and T1 are preferably set to, for example, a time for stopping at a traffic light or the like, for example, about 3 minutes. The times T0 and T1 can be set by operating the computer system via the interface 116. As a result, the user can set the times T0 and T1 as appropriate over a period of several minutes to several hours, for example, according to the operation status of the cargo transportation vehicle. The set time is not limited to this.

  Further, in a state where the trigger level vsh that does not contribute to vibration analysis is not reached, the storage operation to the storage device 117 is stopped, and the processing operation mode of the processing unit 121 is changed to the low power consumption mode, thereby reducing the power consumption. Can be reduced. The low power consumption mode of the processing unit 121 operates, for example, so as to monitor only the trigger pulse from the trigger circuit 115, and when the trigger pulse is supplied from the trigger circuit 115, the processing operation is switched to the normal operation mode. The A / D converter 113, the position detection unit 118, the time detection unit 119, and the environment detection unit 120 are in a state in which data can be taken in, and the data can be written in the storage device 117.

  Further, in this embodiment, a vibration generator 164 is provided in the power supply unit 122 to generate power by vibration generated in a vehicle or the like, to store in the secondary battery 161, and to use the power stored in the secondary battery 161 as a vibration recording device. 100 was stored. As a result, it is possible to prevent the occurrence of a situation in which vibration recording is not performed due to battery exhaustion.

  Furthermore, even when transporting over a long period of time, such as transport between continents, it is possible to record vibration without increasing the capacity of the secondary battery 161.

  In this embodiment, the data stored in the storage device 117 is deleted retroactively for a predetermined time T1 when the storage is stopped. However, the data may be overwritten on the storage device 117 retroactively for a predetermined time T1 when the storage is started. Good.

  In the present embodiment, the current time information is acquired using a radio clock, but the current time information may be acquired using time information included in a signal obtained by a GPS receiver.

  Further, the position detection unit 118 may acquire position information and time information via the interface 116 by using, for example, an existing GPS receiver mounted on a freight transportation vehicle or the like. In addition, the time detection unit 119 may acquire time information via the interface 116 by using, for example, an existing radio clock mounted on a freight transportation vehicle or the like. Furthermore, the environment detection unit 120 substitutes, for example, an existing temperature sensor mounted on a freight transportation vehicle or the like, and connects to the temperature sensor via the interface 116 to acquire temperature data from the temperature sensor. You may do it.

  Further, a photovoltaic generator or the like may be mounted instead of the vibration generator 163, or these may be combined.

  As described above, the position detection unit 118, the time detection unit 119, the environment detection unit 120, and the like are replaced with existing position detection devices, radio clocks, sensors, and the like mounted on a freight transportation vehicle or the like, so that vibration recording can be performed. Since the configuration of the apparatus 100 can be simplified, the vibration recording apparatus 100 can be configured at low cost.

  The vibration recording apparatus 100 is connected to a personal computer or the like via the interface 116, and data related to vibration stored in the storage device 117 is read by the personal computer. In the personal computer, data read from the storage device 117 of the vibration recording device 100 is processed and displayed on a display device or the like.

  Further, by using data stored in the storage device 117 of the vibration recording apparatus 100, a vibration generator or the like can be driven to reproduce the recorded vibration.

  Thereby, it is possible to reproduce the vibration generated in the cargo transportation vehicle and analyze the influence of the vibration on the cargo.

  The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be considered without departing from the gist of the present invention.
