A selection filter 107, and a demodulator 108.

Hereinafter, referring to the role of each component, the antenna 101 serves to receive the RF signal in the air and convert it into an electrical signal on the wire. The band select filter 102 performs bandpass filtering to amplify a signal received from the antenna 101 only to a desired frequency band.

2 is a block diagram illustrating an internal configuration of a wired / wireless signal processing apparatus according to an embodiment of the present invention.

2, the wired / wireless signal processing apparatus includes a wired data receiver 210, a wireless signal receiver 220, a data transmitter 230, a remote controller 240, and an illegal wireless signal determiner 250. .

The wired data receiving unit 210 receives the image data and the audio data received from the wired monitoring device. For example, the wired data receiving unit 210 may receive the image data from the camera means, the wired monitoring device installed in the detection target area, and receive the audio data from the microphone means, the wired monitoring device. Meanwhile, the wired data receiver 210 converts an image signal received from the camera means into an electrical signal including luminance information or color information through a predetermined signal processing process. The electrical signal may be image data in the form of digital data. In addition, the wired data receiving unit 210 converts the voice signal received from the microphone means into an electrical signal through a predetermined signal processing process. The electrical signal may be voice data in the form of digital data.

The radio signal receiver 220 receives a radio frequency signal including image data and audio data.

In one example according to the present invention, the wireless signal receiver 220 receives a radio frequency signal including image data from one or more wireless cameras using different frequencies, and includes a radio frequency including the voice data from one or more wireless microphones. It may also receive a signal. That is, in order to increase a channel by adding a wired camera or a wired microphone in the related art, a circuit must be added in hardware. However, in the present invention, a plurality of wireless cameras or wireless microphones that use a radio frequency band are added and assigned to different frequencies, respectively. In addition, by using a common phase-locked loop circuit, the radio frequency signals received from the wireless camera or the wireless microphone are alternately fixed at high speed, and a demodulation circuit unit and a common digital encoding unit are used to add a circuit without adding a circuit. It is possible to increase the monitoring channel of the area to be detected more conveniently by achieving the same purpose as adding a channel. For example, the wireless signal receiver 220 according to the present invention refers to a radio frequency detection device for detecting a desired radio frequency signal by receiving a radio frequency signal from each of a plurality of radio frequency bands.

3 is a diagram illustrating an example of a circuit diagram according to a configuration of a wireless signal receiver illustrated in FIG. 2.

As shown in the figure, as a component of the wireless signal receiver according to the present invention, an antenna (ANT), a filter (HPF and LPF), a low noise amplifier (LNA), a diplexer, a mixer, a voltage A control oscillator (VCO), a phase locked loop (PLL), a demodulator (Demodulator), a switch (VS), etc., wherein the operation of each component is a component of the conventional radio frequency receiver circuit described above with reference to FIG. Similar to the operations of

In the exemplary embodiment of the figure, the frequency band is divided into three bands, and the first frequency band is divided into 1 MHz and more than 1600 MHz, the second frequency band is divided into 1600 MHz and more than 3200 MHz, and the third frequency band is more than 3200 MHz and less than 6400 MHz. . In addition, the first frequency band is subdivided into two bands of 1 MHz or more and less than 300 MHz and 300 MHz and more than 1600 MHz. By dividing the first frequency band, which is a low frequency band, based on 300 MHz, a separate antenna capable of selectively switching can further increase reception sensitivity. In the circuit diagram, four antennas 301, 302, 303, and 304 may be configured to receive signals in each divided frequency band.

In this circuit diagram, two phase locked loops, PLL (A) 305 and PLL (B) 306, are used as the phase locked loop for frequency lock, and basically the first frequency band is used as the PLL (A) 305. , The second frequency band, and the third frequency band are controlled simultaneously. Specifically, when detecting a radio frequency (RF) signal in a range of 1600 MHz to 3200 MHz, a PLL (A) 305 is used to detect down-converted to a specific IF signal in the middle through 'Mixer4'. Input the frequency signal plus RF and IF to 'Mixer4'.

And, if you want to detect the RF signal in the range of 1MHz ~ 1600MHz, PLL (B) 306 first inputs a signal fixed at 1600MHz frequency to 'Mixer2' first to convert the RF signal (Up Conversion), PLL ( A) 305 inputs a frequency signal plus RF, IF, and 1600 MHz as the detection target to 'Mixer3' to down-convert. Here, the first reason for the up-conversion through 'Mixer2' is that the RF signal in the range of 1MHz to 1600MHz is first up-converted by 1600MHz to be treated like the RF signal in the 1600MHz to 3200MHz range, so that 1MHz ~ This is to control signals in the 1600MHz range at the same time.

In addition, to detect an RF signal in the range of 3200 MHz to 6400 MHz, the multiplier 307 is used to multiply the frequency signal generated from the PLL (A) 305 by 2 and input the signal to 'Mixer4' to download the RF down to IF. Convert Here, the reason for 2 multiplication is to allow for simultaneous control of signals in the 3200 MHz to 6400 MHz range through a single phase-locked loop, taking into account 2 multiplications, which are the frequency ratios in the 1600 MHz to 3200 MHz range and the 3200 MHz to 6400 MHz range, The fixed frequency signal multiplied by 2 is input.

In a more specific example according to the present invention, when a signal (first frequency band) of which RF is 400 MHz is to be demodulated to an FM image, it is fixed at 1600 MHz in the PLL (B) 306 and 2480 MHz ((1600) in the PLL (A). +400) +480). In addition, the antenna switch is switched to HI (high) to select the antenna 'ANT3' in the frequency band corresponding to 400 MHz, and in the switch 309 connected to the image demodulator to select the IF signal passing through the 'Mixer3', Switch VS1 'and' VS2 'to LO (low).

As another example, when the FM signal demodulation of the 2400MHz RF signal (second frequency band), the PLL (B) is irrelevant and is fixed to 2880MHz (2400 + 480) in the PLL (A). In addition, since an RF signal of 2400 MHz corresponds to the second frequency band, the antenna switch is irrelevant, and 'VS1' is LO in the switch 309 connected to the image demodulator to select the IF signal passing through 'Mixer4'. VS2 'switches to HI.

On the other hand, when demodulating the AM image in the frequency detection circuit, the frequency control method is the same as the FM image demodulation except that the IF of the AM image is 479.250 MHz.

The wired / wireless signal processing apparatus according to the present invention outputs an FM audio demodulation signal when a voice detection request is made, and outputs an FM video demodulation signal when a video detection request is made. In addition, AM voice demodulation may be performed using received signal strength (RSSI) 311, 312, and 313. For example, when there is an AM voice detection request, the received signal strength is directly input to the ADC of the CPU of the conventional control board, and is processed in the same manner as the FM voice demodulation signal processing through a separate ADC in parallel and inputted to the CPU. In this case, if the ADC sampling rate of the CPU is more than 8kHz may be processed inside the CPU, if the processing speed is insufficient, a separate audio ADC can be used.

Referring back to FIG. 2, the data transmitter 230 transmits the image data and the audio data to the remote control apparatus. For example, the data transmitter 230 may convert the image data and the audio data into a digital signal through an analog-digital converter (ADC), encode the converted digital signal, and transmit the converted digital signal to the remote control apparatus.

The remote controller 240 controls at least one of the wired data receiver 210, the wireless signal receiver 220, and the data transmitter 230 according to a remote control signal received from the remote controller.
