Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production supplies, in particular to a multifunctional real-time intercom. Background Art
[0002] As a wireless communication tool, walkie-talkies have been widely used in military, commercial and civilian fields since their birth, especially in outdoor operations, emergency rescue and other scenarios. Traditional walkie-talkies mostly use half-duplex radio wave communication modules, which are limited to a one-way communication mode of "you listen to me" or "I speak and you listen". This technical bottleneck limits the immediacy and interactivity of communication, which is particularly inconvenient in emergency or complex working environments.
[0003] In addition, existing walkie-talkies rely on handheld operation, and users need to keep pressing buttons to maintain a call, which not only occupies both hands and affects work efficiency, but also increases the complexity of operation. This defect is particularly prominent when working outdoors or when both hands are required to operate other equipment at the same time. For outdoor workers who use the walkie-talkie for a long time, handheld walkie-talkies are more likely to cause hand fatigue and even operational errors. Utility Model Content
[0004] The purpose of the utility model is to provide a multifunctional real-time intercom, which can improve the above problems.
[0005] The embodiment of the utility model is achieved as follows:
[0006] The utility model provides a multifunctional real-time intercom, which comprises: a mainframe shell, a clamping piece fixed to the back of the mainframe shell, the clamping piece is used to temporarily fix the mainframe shell on a clamping object; a processor and a full-duplex Bluetooth communication module are arranged in the mainframe shell, a microphone and a speaker are arranged on the mainframe shell; the processor is electrically connected to the full-duplex Bluetooth communication module, the microphone and the speaker respectively.
[0007] It can be understood that the present application discloses a multifunctional real-time intercom, including a host housing and a clamp fixed to the back of the host housing, which can temporarily fix the host housing to the user's collar, backpack and other portable clamps without the need for the user to hold it in hand. In addition, a full-duplex Bluetooth communication module is provided in the host housing in the present application, and the Bluetooth BLE protocol is called to realize two-way simultaneous signal transmission and reception, so that the user can free his hands, conduct real-time two-way conversations and improve work efficiency. In addition to two-way communication, the intercom disclosed in the present application can also be connected to other smart terminals such as mobile phones through the Bluetooth module to realize functions such as call connection and music playback.
[0008] In an optional embodiment of the utility model, the full-duplex Bluetooth communication module includes an antenna, a phase-locked loop, a transmitting signal amplifier and a low-pass filter, and the phase-locked loop, the transmitting signal amplifier and the low-pass filter are connected in sequence between the processor and the antenna; the full-duplex Bluetooth communication module also includes a bandpass filter, a receiving signal amplifier, a mixer, a crystal filter, an intermediate frequency processing chip and a ceramic filter; the bandpass filter, the receiving signal amplifier, the mixer, the crystal filter, the intermediate frequency processing chip and the ceramic filter are also connected in sequence between the antenna and the processor.
[0009] It can be understood that for the signal transmission process, the phase-locked loop and the voltage-controlled oscillator therein generate the transmitted RF carrier signal, which is buffered and amplified by the transmission signal amplifier, excitation amplified, and power amplified to generate the rated RF power, and then passes through the low-pass filter to suppress the harmonic components, and then is transmitted through the antenna. For the signal reception process, the receiving part is a secondary frequency conversion superheterodyne method. The signal input from the antenna is amplified by the radio frequency after passing through the transceiver conversion circuit and the bandpass filter, and then passes through the bandpass filter and the receiving signal amplifier, and enters a mixer. The amplified signal from the radio frequency is mixed with the first local oscillator signal from the phase-locked loop frequency synthesizer circuit at the mixer to generate a first intermediate frequency signal; the first intermediate frequency signal is further eliminated by the crystal filter. The first intermediate frequency signal after filtering enters the intermediate frequency processing chip, and is mixed again with the second local oscillator signal to generate a second intermediate frequency signal. The second intermediate frequency signal is transmitted to the processor after filtering out useless stray signals through a ceramic filter.
[0010] In an optional embodiment of the present invention, a key area is further provided on the host housing, and the keys on the key area are electrically connected to the processor.
[0011] In an optional embodiment of the present invention, the clamping member includes a clamping body, an elastic hinge and a clip, the clip is hinged to the clamping body through the elastic hinge, and the clamping body is fixed to the back of the host housing.
[0012] In an optional embodiment of the utility model, the clamping piece further comprises a first magnetic sheet, and a groove is provided on the surface of the clamping sheet away from the clamping body, and the shape and size of the groove match the first magnetic sheet, and is used to fasten and accommodate the first magnetic sheet. It can be understood that in some field operation scenarios, the first magnetic sheet can be inserted into the groove of the clamping sheet, and the entire walkie-talkie can be fixed on a certain iron object for use, which can also play the role of freeing the operator's hands.
[0013] In an optional embodiment of the utility model, a second magnetic sheet is further arranged in the groove of the clip, and the magnetic properties of the second magnetic sheet are opposite to those of the first magnetic sheet. It can be understood that the second magnetic sheet is arranged in the groove, which can effectively absorb the first magnetic sheet, so that the first magnetic sheet is more firmly clamped in the groove of the clip.
[0014] In an optional embodiment of the utility model, a third magnetic sheet is provided on the surface of the clamping body facing the host housing, and a fourth magnetic sheet is provided on the back of the host housing, and the third magnetic sheet and the fourth magnetic sheet have opposite magnetism. It can be understood that the clamping body can be detachably fixed to the host housing through the third and fourth magnetic sheets with opposite magnetism. In some outdoor operation scenarios, the user can remove the host housing separately, and fix the entire intercom on an iron object through the fourth magnetic sheet for use, which can free the operator's hands in a small space.
[0015] In an optional embodiment of the present invention, a waterproof sealing ring is provided on the closed opening of the host housing.
[0016] In an optional embodiment of the utility model, the host housing is also provided with an LED lighting lamp electrically connected to the processor. It can be understood that when the user uses it at night or in a dark environment, the LED lighting lamp can provide ambient lighting.
