Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of a passive vibration recording apparatus according to an embodiment of the present invention, which is suitable for recording whether an object falls off during transportation. As shown in fig. 1, a passive vibration recording apparatus 100 according to a first embodiment of the present invention includes: the vibration sensing module 110, the rectifying module 120, the voltage stabilizing module 130 and the recording module 140.
The vibration sensing module 110 is used for sensing vibration of an object and converting a vibration signal of the object into an electrical signal. In the transmission process, the falling or violent collision of the object inevitably causes vibration of the object with certain intensity, and in a general case, the vibration condition of the object can be represented by a waveform, as shown in fig. 2, the vibration process of the object is divided, a [ t0, t1] time period is a vibration starting stage, a [ t1, t2] time period is a peak stage, a [ t2, t3] time period is a damping stage, and almost no vibration exists after a t3 time point, which indicates that the vibration of the object caused by the falling is damped, and the object enters a state after the falling. The vibration of the object can generate energy, the vibration energy of the object is converted into electric energy, and the electric energy can be generated for the passive vibration recording device through the vibration of the object, so that the passive vibration recording device does not need an additional power supply to supply power. After the vibration sensing module 110 senses the vibration caused by the falling of the object, the vibration signal of the object can be converted into an electrical signal, and in general, the vibration signal in the time period of the object [ t0, t2] is converted into the electrical signal. In this embodiment, the vibration sensing module 110 may be any device capable of converting a vibration signal of an object into an electrical signal, and preferably, the vibration sensing module 110 is a vibration stress sheet and is a sheet-shaped object capable of converting a vibration signal into an electrical signal.
The rectifying module 120 is connected to the vibration sensing module 110, and is configured to convert the electrical signal output by the vibration sensing module 110 into a pulsating direct current electrical signal; the voltage stabilizing module 130 is connected to the rectifying module 120, and is configured to convert the pulsating dc signal output by the rectifying module 120 into a stable power supply voltage, and supply power to the recording module 140 through the power supply voltage. The magnitude (voltage level) and direction (voltage positive and negative) of the electrical signal output by the vibration sensing module 110 are constantly changing with time, and the power supply voltage of the general components is a voltage requiring a stable direct current voltage, that is, a voltage whose magnitude and direction are not changing with time. Therefore, the rectifying module 120 rectifies the ac signal output by the vibration sensing module 110 to convert the ac signal into a dc signal, and the dc signal output by the rectifying module 120 is generally unstable and does not have to meet the power supply voltage required by the subsequent modules, so the voltage stabilizing module 130 is required to convert the dc signal output by the rectifying module 120 to output a dc signal with a proper and stable size. In this embodiment, the rectifying module 120 may be any rectifying circuit capable of converting ac power into dc power, such as a half-wave rectifying circuit, a full-wave rectifying circuit, or a bridge rectifying circuit. The voltage stabilizing module 130 may be any voltage stabilizing circuit, such as a series voltage stabilizing circuit, capable of converting the output dc signal of the rectifying module 120 into a stable dc signal required by the post-recording module 140.
The recording module 140 is connected to the voltage stabilizing module 130, and starts to operate with the supply voltage output by the voltage stabilizing module 130 as a working voltage to record the vibration data of the object. The stable power supply voltage with a proper output voltage of the voltage stabilizing module 130 can supply power to the recording module 140, and when the recording module 140 obtains the working voltage, the recording module starts working, and according to the vibration recording data of the object, when the object stops vibrating, the vibration sensing module 110 cannot respond to the vibration signal, so that the power supply voltage output by the voltage stabilizing module 130 is 0, and the recording module 140 stops working. Therefore, whether the object vibrates and the time length of the vibration can be judged through the data volume recorded from the start to the stop of the recording module 140, for example, the speed of the data recorded by the recording module 140 is 1KB/s, that is, the recording module 140 can record the data volume of 1KB per second, if the data volume recorded by the recording module 140 is 2KB, the object can be judged to vibrate and the vibration time length is 2 seconds, so as to judge that the object falls or violently collides; if the data volume of the recording module 140 is 0, it can be determined that the object does not vibrate, and thus it is determined that the object does not fall or collide with the object.
The passive vibration recording device provided by the embodiment of the invention comprises a vibration sensing module, a rectifying module, a voltage stabilizing module and a recording module, so that the monitoring and recording of the vibration of an object in the transportation process are realized, whether the object falls or violently collides in the transportation process is judged, and a reference basis is provided for the responsibility judgment of the damage of the object. The vibration energy generated by the vibration of the object is converted into electric energy through the vibration induction module, the rectification module and the voltage stabilizing module, so that the passive vibration recording device provided by the embodiment of the invention does not need an additional independent power supply (namely a battery) to supply power to the recording module, and the volume of the passive vibration recording device is small.
Example two
Fig. 3 is a schematic structural diagram of a passive vibration recording apparatus according to a second embodiment of the present invention, which is further optimized in the first embodiment. As shown in fig. 2, a passive vibration recording apparatus 100 according to a second embodiment of the present invention includes: the vibration sensing module 110, the rectifying module 120, the voltage stabilizing module 130, the recording module 140, and the filtering module 150, wherein the structures and functions of the vibration sensing module 110, the rectifying module 120, and the voltage stabilizing module 130 are the same as those of the above embodiments, and are not described herein again.
The filtering module 150 includes a first filtering capacitor C1 and a second filtering capacitor C2. The first filter capacitor C1 is connected to the output of the rectifier module 120. Although the rectifying module 120 converts the ac electrical signal output by the vibration sensing module 110 into a pulsating dc electrical signal, the pulsating dc electrical signal output by the rectifying module 120 still has an ac electrical signal with a certain component, and the first filtering capacitor C1 functions to filter the ac component in the pulsating dc electrical signal output by the rectifying module 120 and increase the dc component in the input electrical signal of the voltage stabilizing module 120. In addition, the first filter capacitor C1 may also store energy of an ac signal in the pulsating dc signal output by the rectifier module 120, so as to improve the durability and stability of the input electrical signal of the voltage regulator module 130.
The second filtering capacitor C2 is connected to the output end of the voltage regulator module 130, and is used for filtering the output supply voltage of the voltage regulator module 130, reducing ripples in the supply voltage generated by voltage conversion performed by the voltage regulator module 130, and making the waveform of the supply voltage output by the voltage regulator module 130 smoother, i.e., the output supply voltage is more stable.
According to the embodiment of the invention, the first filter capacitor in the two-way filter module filters the electric signal output by the rectifying module, and the second filter capacitor filters the power supply voltage output by the voltage stabilizing module, so that the stability of a circuit in the passive vibration recording device is further improved.
EXAMPLE III
Fig. 4 is a schematic structural diagram of a passive vibration recording apparatus according to a third embodiment of the present invention, which is a further refinement of the recording apparatus in the foregoing embodiments. As shown in fig. 4, a passive vibration recording apparatus 100 according to a third embodiment of the present invention includes: the vibration sensing module 110, the rectifying module 120, the voltage stabilizing module 130, the recording module 140, and the filtering module 150, wherein the structures and functions of the vibration sensing module 110, the rectifying module 120, the voltage stabilizing module 130, and the filtering module 150 are the same as those of the above embodiments, and are not described herein again.
The recording module 140 includes: a clock signal generation unit 141, a data control unit 142, and a storage unit 143. The clock signal generating unit 141, the data control unit 142, and the storage unit 143 are all connected to the voltage stabilizing module 130, and when the object vibrates, the voltage stabilizing module 130 provides stable operating voltage for the clock signal generating unit 141, the data control unit 142, and the storage unit 143.
The clock signal generating unit 141 is connected to the data control unit 142, and is configured to send a clock signal with a certain frequency to the data control unit 142; the data control unit 142 is connected to the storage unit 143, and is configured to write vibration data into the storage unit 143 according to a clock signal sent by the data control unit 142; the storage unit 143 is used to store the vibration data written by the data control unit 142. When the object vibrates, the data control unit 142 is used for writing data into the storage unit 143 to record the vibration of the object, and the data control unit 142 needs a driving signal for performing operation, and the driving signal is a clock signal with a certain frequency sent by the clock signal generating unit 141. The data control unit 142 writes data into the storage unit 143 once without receiving a clock signal, and after the object vibration is over, the data control unit 142 is powered off, stops writing data into the storage unit 143, and judges whether the object vibrates and the vibration time length according to the data amount stored in the storage unit 143. For example, if the frequency of the clock signal transmitted by the clock signal generation unit 141 is 50Hz, it indicates that the data control unit 142 writes data into the storage unit 143 50 times per second, and if the data control unit 142 writes data into the storage unit 143 50 times per second, the data amount is 1KB, and if the data amount stored in the storage unit 143 is 2KB, it may be determined that the object has vibrated and the vibration duration is 2 seconds, and thus it may be determined that the object has fallen or has collided violently; if the amount of data stored in the storage unit 143 is 0, it can be determined that the object does not vibrate, and thus it can be determined that the object does not fall or collide with the object.
In this embodiment, the frequency of the clock signal transmitted by the clock signal generating unit 141 to the data control unit 142 may be set according to actual conditions, and the data amount of the data written into the storage unit 143 by the data control unit 142 per second may also be set according to actual conditions, which is not limited in this embodiment.
Further, the data control unit 144 is further configured to count according to the clock signal sent by the clock signal generating unit 141. When the object vibrates, the voltage stabilizing module 130 provides a stable working voltage to the data control unit 144, the counting of the data control unit 144 starts from 0, the data control unit 144 adds 1 to the counting information and writes the counting information into the storage unit 141 every time the data control unit 144 receives a clock signal sent by the clock signal generation unit 141, after the object vibrates, the voltage stabilizing module 130 cannot provide the stable working voltage for the data control unit 144, the counting stops after the data control unit 144 is powered off, when the object vibrates next time, the data control unit 144 still counts from 0, and the number of times of the object vibrating can be known by looking up the counting information in the storage unit 144. For example, the count information in the storage unit 144 is 0123450123456, indicating that the object has twice vibrated.
The passive vibration recording device provided by the third embodiment of the invention completes the recording of data during the vibration of the object through the clock signal generating unit, the data control unit and the storage unit, thereby judging whether the object vibrates and the vibration generation duration, and the passive vibration recording device is simple in design and easy to realize.

The peak detection module 160 is connected to the vibration sensing module 110 and is configured to detect a maximum amplitude of the electrical signal generated by the vibration sensing module 110. As shown in fig. 2, the time period [ t1, t2] is the peak period of the vibration, and the vibration amplitude of the object reaches the maximum amplitude at this time, because the vibration sensing module 110 converts the vibration signal of the object into an electrical signal, when the vibration signal of the object reaches the maximum amplitude, the ac electrical signal output by the vibration sensing module 110 also reaches the maximum amplitude, and the maximum amplitude of the vibration of the object can be known by recording the maximum amplitude of the electrical signal generated by the vibration sensing module 110.
