2A to 2C are block diagrams showing a smart bolt 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 transmits the remaining amount information of the power supply unit 150 to the repeater 210 through the wireless communication unit 140 in a first period (eg, 30 seconds), 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 converts a voltage sensor 131a that senses a voltage change of the load cell 131 and a loosening value that converts the voltage change of the voltage sensor 131a into an unlocked value of the volt unit 110 The unit 131b and a frequency converter 131c for converting a 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 in which the load cell 131 is strongly adhered 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 approximately 1mm away from the object to be bound), it has a loosely contacted state. Accordingly, the load cell 131 outputs different resistance values, that is, voltage values, before and after the smart bolt 100 is loosened. Moreover, when there is vibration in the object to be bound, the load cell 131 also vibrates, so the output voltage value also has a predetermined frequency and changes.

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 conversion unit 131c is the voltage sensor 131a. The frequency, that is, the frequency of the smart volt 100 is calculated based on the change in the voltage value measured from.

In some examples, the control board 120 may receive an unlocked value from the unlocked value converting unit 131b and receive a frequency from the frequency converting unit 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 (that is, the load cell 131), and this is the wireless communication unit 140 ) Can be transmitted to the repeater 210. 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) connected to the control board 120 to sense the frequency of the bolt unit 110, and the control board 120 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 connected to the control board 120 to emit light when the loosening value and/or the frequency of the bolt unit 110 is greater than a threshold value.

In some examples, the control board 120 is greater than a preset threshold value, or the amount of power remaining in the power supply unit 150 is a preset threshold value and/or the unlocking value and/or frequency of the smart bolt 100 sensed from the sensor unit 130. 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 follows up work (for example, grasping the fastening state of the smart bolt 100, the vibration state, and the remaining amount of the power supply unit 150) You can do it.

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

As shown in FIG. 2C, in some examples, the smart bolt 100 includes a rectifying unit 132a connected to the piezoelectric element 132, a battery 150 connected to the rectifying unit 132a to be charged, and the piezoelectric element 132. A voltage sensor 132b for sensing a voltage change, and a frequency converter 132c for converting a voltage change of the voltage sensor 132b into a frequency may be further included.

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

In some examples, the control board 120 may receive information on the remaining amount of the battery from the battery 150 as well as the frequency of the smart bolt 100 from the frequency converter 132c, and 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 an embodiment of the present invention may transmit not only its own loosening information, but also information about the vibration frequency of the smart bolt 100 and the remaining amount of the power supply 150 to the repeater 210. Moreover, when the loosening value, the frequency of the smart bolt 100, and/or the remaining amount of the power supply unit 150 is higher or smaller than the threshold value, by displaying through the light emitting unit 180, the operator can indicate the state of the smart bolt 100 Make it easy to recognize. In some examples, a sound unit may be additionally configured to the light emitting unit 180 to audibly warn the state of the smart bolt 100.
