Referring to FIG. 1, a safety cap for earthquakes according to a preferred embodiment of the present invention includes a vibration detection sensor 10 that detects occurrence of an earthquake, and a power supply unit for each part when the occurrence of an earthquake is detected from the vibration detection sensor 10. A control unit 20 for supplying power of 50 and controlling the audio or sound stored in the memory 40 to be output through the audio output unit 30; and radio reception for receiving a radio broadcast and outputting it through the audio output unit 30 Unit 60, radio communication unit 70 capable of communicating with a disaster countermeasure center, if necessary, and operation input unit 80 capable of selecting the radio reception unit 60 and radio communication unit 70 and inputting an operation command such as variable frequency It is comprised including.

FIG. 2 is a flowchart of a method for operating an earthquake safety cap according to a preferred embodiment of the present invention, which will be described in detail along with the operation of the circuit attached to the safety cap described with reference to FIG. 1 above. .
First, in step S21, it is detected whether an earthquake has occurred. In this case, the control unit 20 determines an electrical signal according to the vibration detected by the vibration detection sensor 10 to confirm whether or not an earthquake has occurred.

When an earthquake occurs, the duration and extent of the earthquake will be grasped, and if there is an earthquake that does not cause damage in less than the set time, it should not be judged as an earthquake. Can do.
The vibration detection sensor 10 can use a gyro sensor, and power of the power supply unit 50 is supplied only to the vibration detection sensor 10 and the control unit 20 in order to minimize power consumption in a standby state. Can be configured.

If the signal detected by the vibration detection sensor 10 is determined by the control unit 20 as a result of occurrence of an intensity greater than or equal to the setting and the duration, the control unit 20 determines that the power of the power supply unit 50 is supplied as in step S22. The audio or acoustic signal stored in the memory 40 is output through the audio output unit 30 so that it can be supplied to each unit mentioned later.
The audio signal is preferably performed in a language that can be recognized by the user, such as “please wear a safety cap”, “3rd floor corridor”, “teaching room”, etc. The sound is guided so that people around the safety cap can easily find the location where the safety cap is placed when an earthquake occurs.

In this way, by guiding to the position of the safety cap by voice or sound, it becomes possible to easily find and wear the safety cap even when the power is cut off due to the occurrence of an earthquake, and therefore, protection can be provided in the event of a disaster. Damage to human lives can be minimized by increasing the rate of wearing of orthoses.
If necessary, the control unit 20 can not only output the voice or sound but also blink the lamp unit 90 provided on the front surface of the safety cap to inform the position where the safety cap is placed.

Next, when the user searches for a position where the user puts the safety hat and wears the safety hat, the output of the voice or sound for informing the position of the previous safety hat stops. This is automatically performed through a separate sensor, or is performed when a user wearing a safety cap presses a specific button of the operation input unit 80.
As in the determination result of step S23, the state where sound or sound is output through the sound output unit 30 is maintained until the safety cap is worn, and when the user wears the safety cap, the step is performed. The output of voice and sound is interrupted as in S24.

  Next, as in step S <b> 25, the control unit 20 confirms whether the user has selected a radio or wireless communication function through the operation input unit 80. It can be set to perform a radio reception or a radio communication function after performing step S24 automatically without performing such a confirmation step. In particular, the safety cap placed in preparation for school can maintain an audio output that repeatedly explains the save position so that the child can be safely guided to the save place.

When the radio function is selected through the operation input unit 80, as shown in step S26, the radio broadcast of the set frequency received by the radio reception unit 60 is output through the audio output unit 30, and the safety hat wearer Be able to save while listening to disaster information broadcasts.
In fact, it is known that local programs or local shortwave broadcasting can immediately reflect the situation in the area rather than nationwide broadcasting in various disaster situations, so it is practically helpful. Can be set to a local program channel.

  If the user requests to change the channel through the operation input unit 80 in step S27, the channel received by the radio receiving unit 60 is changed and the radio broadcast of the changed channel is received as in step S28. Received at 60 and output through the audio output unit 30. In addition, when the wearer selects wireless communication through the operation input unit 80 in the radio reception state, the wireless communication function is performed as in step S29 and other safety hat wearers or disaster countermeasures in the vicinity are performed through the wireless communication unit 70. You can perform voice communication with the center.

  Therefore, the present invention makes it possible for people in the vicinity to recognize the position where the safety hat is placed and to listen to the disaster broadcast while wearing the safety hat and to avoid it, or Through the communication with the safety hat wearers, it is possible to quickly confirm the retreat position and retreat.
