PTT switch 300 to act as a switch to transmit the contents of the call to the command center transceiver and fellow firefighter transceiver using the omni-directional transmission microphone 121 and is mounted on the body portion of the firefighter (300) ).

Therefore, these quotations are attached to the inside of the helmet, and the receiver is automatically received by both ears, so that they can be heard in the field of fire and rescue work, and since the microphone is installed inside the helmet, a separate earphone is unnecessary. This has the advantage of simplifying the structure and focusing on disaster prevention work.

On the other hand, the citation is to install a wireless transceiver 200 on the back of the firefighter and the PTT switch 300 and the helmet 101 is attached to one side of the body and the wires 101, so the wires, poor suppression or operation In many cases, the radio transceiver 200 or the PTT switch 300 may be damaged by environmental shocks or high temperatures, and in addition, the PTT switch 300 may be separately operated because it is necessary to carry various equipment in both hands. There is a problem that it becomes difficult to do so that efficient work becomes difficult.

An object of the present invention is to provide a transmission and reception helmet that allows two-way communication without the need to operate a separate PTT switch and to embed any equipment necessary for wireless communication in the helmet to solve this problem.

In order to achieve this purpose, the present invention proposes a transmission and reception helmet made by installing a wireless transmission / reception module, a VOX module and an audio processor as well as a speaker and a microphone inside the helmet.

Accordingly, the present invention enables firefighting or personnel participating in various operations to be able to perform two-way communication by simply mounting only one helmet, which enables efficient work, and furthermore, there is no need to operate the PTT switch. It is possible to work more efficiently using both hands.

This invention is described in more detail with reference to the accompanying drawings as follows.

As shown in FIG. 2, the present invention is to incorporate all the equipment necessary for two-way communication inside the helmet, thereby enabling two-way communication by simply wearing a helmet. In addition, the present invention is that the operation mode is switched to the reception mode and the transmission mode by the microphone 1 built in the helmet can be used conveniently because a separate PTT switch operation is unnecessary.

That is, as shown in FIG. 3, the present invention has a speaker 2 installed at both sides of the helmet, and a microphone 1 installed at the front, and a transmission / reception module (3, 4), a VOX (5) and an audio processor (6). ) Is installed inside the upper part of the helmet.

As can be seen from the above, the present invention provides a transmission / reception antenna 8, a high frequency reception signal processor 9, a voice signal demodulator 10, a voice output amplifier 11, a speaker 2, and the like. A well-known module comprising a receiving module 3, a transmitting module 4 including a microphone 1, an oscillator 13, and the like, and a microprocessor 7 for transmitting and receiving control, channel display, and operation display. The audio processor 6 is connected to the microprocessor 7, the oscillator 13 and the audio signal demodulator 10, the audio output amplifier 11, the microphone 1, the audio processor 6, and the microprocessor. It consists of VOX (5) connected between (7).

The present invention as described above is to supply the power to each part of the circuit when the power switch 'on' not shown in the state wearing a helmet in the state as shown in FIG. In this case, the microprocessor 7 initializes the audio processor 6 and then detects the output signal of the VOX 5 so that the wearer is speaking when the signal level of the microphone 1 is above a predetermined level. The voice signal is transmitted to the audio processor 6 through the VOX 5, and the voice signal is applied to the oscillator 13 of the transmission module 4, modulated to a carrier frequency, and then amplified by a high frequency power as usual. It is sent to the transmitting and receiving antenna 8. Accordingly, in the transmitting and receiving antenna 8, the wearer's voice signal is transmitted through radio waves. Therefore, the response radio wave is transmitted from the radio equipment installed in the headquarters or the helmet of the colleague, which is transmitted to the transmission and reception antenna 8 and passes through the transmission and reception antenna 8 and the high frequency reception signal processing unit 9, and then the audio signal recovery. The audio signal is output through the grandfather 10. In this design, the VOX 5 is connected to the audio processor 6 only when the sound level of the microphone 1 determined by the microprocessor 7 is lower than or equal to the set level. The voice signal output is amplified by the voice output amplifier 11 to shut off the microphones 1 to drive the speaker 2, so that the voice transmitted from the headquarters or the coworker's wireless facility is heard, thereby enabling bidirectional communication. .
