2A to 2C are block diagrams showing a smart vault 100 according to an embodiment of the present invention.

As shown in FIG. 2A , the smart bolt 100 according to an embodiment of the present invention may include a control board 120, a sensor unit 130, a wireless communication unit 140, and a power supply unit 150.

In some examples, the control board 120 includes a processor and memory, and may be provided on a printed circuit board as described above.

In some examples, the control board 120 transmits bolt loosening information to the repeater 210 through the wireless communication unit 140 at a first cycle (eg, 30 seconds), but the loosening value of the bolt unit 110 If it is greater than the threshold value, the loosening information of the bolt unit 110 may be transmitted to the repeater 210 through the wireless communication unit 140 in a second cycle (eg, 2 seconds) faster than the first cycle.

In some examples, the control board 120 transmits the remaining amount information of the power supply unit 150 to the repeater 210 through the wireless communication unit 140 in a first cycle (eg, 30 seconds), but the power supply unit 150 When the remaining amount is less than the threshold value, the remaining amount information of the power supply unit 150 may be transmitted to the repeater 210 through the wireless communication unit 140 in a second period (eg, 2 seconds) faster than the first period.

Referring to FIG. 2B , the sensor unit 130 may include a load cell 131 . In some examples, the smart bolt 100 includes a voltage sensor 131a that senses a voltage change of the load cell 131 and a release value conversion that converts the voltage change of the voltage sensor 131a into a release value of the bolt unit 110 The unit 131b and a frequency conversion unit 131c that converts the voltage change of the voltage sensor 131a into a frequency may be further included.

In some examples, when the smart bolt 100 is first fastened to the binding object, the load cell 131 has a state of being strongly attached to the binding object, but when the smart bolt 100 is released from the binding object for reasons such as vibration of the binding object (For example, when the bolt head 111 of the smart bolt 100 is spaced apart from the object to be bound by about 1 mm) it has a loosely adhered state. Accordingly, the load cell 131 outputs different resistance values, that is, voltage values, before and after the loosening of the smart bolt 100. Moreover, when there is vibration in the object to be bound, since the load cell 131 also vibrates together, the output voltage value also changes with a predetermined frequency.

In some examples, the loosening value conversion unit 131b calculates the loosening value of the smart bolt 100 based on the voltage value measured from the voltage sensor 131a, and the frequency converter 131c calculates the voltage value measured by the voltage sensor 131a. The frequency, that is, the frequency of the smart bolt 100 is calculated based on the change in the measured voltage value.

In some examples, the control board 120 may receive a release value from the release value converter 131b and receive a frequency from the frequency converter 131c. That is, the control board 120 simultaneously extracts the loosening value of the smart bolt 100 and the frequency of the smart bolt 100 from one sensor unit 130 (ie, the load cell 131), and extracts them from the wireless communication unit 140. ) It can be transmitted to the relay 210 through. Accordingly, the circuit structure of the smart bolt 100 can be simplified.

In some examples, the sensor unit 130 may further include a separate vibration sensor (not shown) that is connected to the control board 120 and senses the frequency of the bolt unit 110, and the control board 120 vibrates. The frequency may be received from the sensor and transmitted to the repeater 210 through the wireless communication unit 140 .

In some examples, the smart bolt 100 may further include a light emitting unit 180 that is connected to the control board 120 and emits light when a loosening value and/or a frequency of the bolt unit 110 is greater than a threshold value.

In some examples, the control board 120 determines that the loosening value and/or the frequency of the smart bolt 100 sensed by the sensor unit 130 is greater than a preset threshold value, or the remaining amount of the power supply unit 150 is a preset threshold value. If it is smaller than the value, the light emitting unit 180 may be operated. Therefore, the operator sees the light emitted from the smart bolt 100, recognizes that it is in an abnormal state, and performs subsequent work (eg, grasping the fastening state of the smart bolt 100, the vibration state, and the remaining amount of the power supply unit 150) can be performed.

In some examples, power supply 150 may include a rechargeable battery, and the battery may be charged by piezoelectric element 132 and rectifier 132a. This structure is particularly advantageous for the smart bolt 100 coupled to a binding object such as a motor or pump having severe vibration.

As shown in FIG. 2C , in some examples, the smart bolt 100 includes a rectifier 132a connected to the piezoelectric element 132, a battery 150 connected to the rectifier 132a to be charged, and a piezoelectric element 132. It may further include a voltage sensor 132b that senses a voltage change and a frequency converter 132c that converts the voltage change of the voltage sensor 132b into a frequency.

The piezoelectric element 132 generates power by receiving a vibration shock from the outside, thereby generating AC voltage. The rectifier 132a rectifies the AC voltage and outputs it as a DC voltage. The power supply unit 150 (eg, a battery) may be charged by the DC voltage of the rectification unit 132a. In some examples, the voltage sensor 132b senses the voltage output from the piezoelectric element 132, and since the sensed voltage is an alternating current, the generation frequency is also sensed. Therefore, the frequency conversion unit 132c can extract the frequency using the AC voltage output from the voltage sensor 132b, and eventually the control board 120 determines the frequency of the smart bolt 100 from the piezoelectric element 132. can be extracted.

In some examples, the control board 120 may receive not only the battery remaining capacity information from the battery 150, but also receive the frequency of the smart bolt 100 from the frequency conversion unit 132c, such that the battery 150 The remaining amount information and the frequency of the smart bolt 100 may be transmitted to the repeater 210 through the wireless communication unit 140 .

In this way, the smart bolt 100 according to the embodiment of the present invention can transmit not only its unlocking information, but also the vibration frequency of the smart bolt 100 and the remaining amount information of the power supply unit 150 to the repeater 210. Furthermore, when the loosening value, frequency of the smart bolt 100 and/or the remaining amount of the power supply unit 150 are higher or lower than the threshold value, the light emitting unit 180 displays the status so that the operator can check the state of the smart bolt 100. make it easy to recognize. In some examples, a sound unit may be further configured in addition to the light emitting unit 180 to audibly warn the state of the smart bolt 100.
