Referring to fig. 4-7, the power supply uses an 8.4V rechargeable battery as a main power supply, a 27V external direct current as an external standby power supply, and the secondary power supply required by the detector is 3.3V, 1.5V, 1.1V and +/-5V, and a universal voltage chip is selected according to the required power and application to realize power conversion.
Referring to fig. 8-10, the core control is built by adopting an architecture of an MCU+FPGA, and the FPGA is mainly responsible for completing the sending and receiving of signals in cooperation with the radio frequency module and changing corresponding signal contents according to instructions of the MCU. The MCU is responsible for communication with an upper computer, monitoring a power supply, configuring an FPGA program, switching control and the like.
The embodiment also comprises an interface module, wherein the interface module comprises a multifunctional multiplexing interface, two antenna interfaces, two altimeter interfaces and an expansion interface, the multifunctional multiplexing interface is used for integrating MCU program downloading, FPGA configuration loading and battery charging functions, and the expansion interface comprises two SPI communication pins and a general IO port and is used for externally connecting a new module, as shown in FIG. 11.
In the embodiment, the wireless communication adopts a split type design, so that the wireless communication needs to be encrypted in order to meet the confidentiality requirement, point-to-point communication is abandoned in the embodiment, and the work function expansion is realized in a networking communication mode;
The wireless communication relates to the audio encoding function, in this embodiment, the audio encoding and decoding are implemented by using the earphone of the wireless communication, and referring to fig. 13, the encoding and decoding flow is implemented by a circuit.
The upper computer part is matched with the functions of corresponding buttons, switches and other controls on a program interface, an IPS industrial capacitive touch display screen is adopted, comfortable and efficient man-machine interaction experience is provided for a user, a man-machine interaction board card is mainly used for carrying a linux system, a QT interface is adopted for realizing man-machine interaction, and the inside is communicated with an MCU through an SPI bus to issue control instructions.
The radio frequency part is constructed based on the zero intermediate frequency software radio technology, the simplification and miniaturization of a hardware circuit are realized by simplifying the mixing link in the traditional superheterodyne architecture, and the radio frequency part effectively reduces the occupation of physical space while maintaining the high-precision signal processing capability, so that the radio frequency part is particularly suitable for application scenes sensitive to volume and power consumption. The whole scheme is composed of a controller, a filter bank, a radio frequency switch, a phase-locked loop PLL, a direct digital frequency synthesizer DDS and other key modules, and the whole flow operation from radio frequency signal receiving, processing and transmitting is completed through the cooperation of digital and analog circuits, and is described with reference to figure 14.
In the embodiment, the signal processing of the receiving channel starts from amplitude limiting protection, the externally input radio frequency signal firstly passes through the amplitude limiter, the core function of the signal processing device is to limit the signal amplitude within a safe working range, the damage of devices caused by overload or burst high-power signals of a later-stage circuit is prevented, the signal subjected to amplitude limiting processing enters a preselection filter bank, the filter bank comprises six independent frequency bands, and the filter channel of the corresponding frequency band is selected by a controller. Each filter is designed for a specific frequency range, effectively suppressing out-of-band interference signals while ensuring low loss transmission of useful signals.
The pre-filtered signal enters a digital control attenuator link, and the module adjusts the attenuation through a digital control signal and dynamically adjusts the gain of a receiving channel. The controller automatically adjusts the attenuation value according to the signal intensity, so that the small signal can be effectively amplified, the saturation of an amplifier caused by a large signal is avoided, the system can adapt to input signals with different intensities, and stable signal processing quality is maintained. The attenuated signal is initially amplified by a low noise amplifier, so that the strength of the weak signal is improved, and enough signal amplitude is provided for subsequent demodulation processing. The low noise nature of the amplifier ensures that the signal to noise ratio of the signal does not significantly degrade during amplification.
Aiming at the processing requirement of broadband signals, the system is provided with a frequency band switch at the demodulation front end. When the input signal belongs to the low frequency band, the switch guides the input signal to the mixing channel, up-conversion processing is carried out on the input signal and the point frequency model generated by the phase-locked loop PLL1, the signal is moved to the frequency band suitable for the demodulator to work, and when the signal is in the high frequency band, the signal directly enters the demodulation link through the switch through path. The IQ demodulator receives the radio frequency signal after frequency division processing, carries out quadrature demodulation with the broadband signal generated by the phase-locked loop PLL2, separates out I-path and Q-path baseband signals, amplifies and filters the two paths of signals output by demodulation, and removes high-frequency residual components to form an analog signal meeting the sampling requirement of the subsequent ADC.
The transmitting channel adopts a symmetrical design architecture with the receiving channel. The IQ signal generated by the baseband processing is amplified and filtered and then enters an IQ modulator, and quadrature modulation is carried out on the IQ signal and the broadband signal generated by the phase-locked loop PLL2, so that the baseband signal is moved to a target radio frequency band. The modulated radio frequency signal is processed by a frequency band dividing switch, the frequency band to be subjected to down-conversion is mixed with the point frequency signal of the PLL1, the original frequency is kept for the straight-through frequency band, and a subsequent numerical control attenuator is used for accurately adjusting the transmitting power, so that the dynamic adjustment of the transmitting intensity is realized through digital control. The drive amplifier power boosts the signal to ensure that the output signal reaches the desired transmit power level. The final-stage preselection filter bank carries out-of-band spurious suppression on the emission signal, and six segmented filters of the final-stage preselection filter bank can effectively filter harmonic components, so that the spectral purity of the output signal is ensured.
In the receiving channel of this embodiment, the FPGA receives the digital IQ signal from the ADC sample, and extracts the phase information through the amplitude threshold decision. For a 4PSK modulated signal, when the I and Q signal amplitudes are both in a certain range, the system determines that the current symbol phase is 45 degrees and corresponds to baseband data 00. The frequency information is obtained by calculating the phase change rate between adjacent symbols, and the frequency modulation characteristics of the signals are extracted. The inverse process of the transmitting channel realizes the generation of baseband signals by the FPGA, the data to be transmitted is mapped into corresponding IQ amplitude combinations, and analog baseband signals are formed through digital-to-analog conversion. The whole processing process adopts a digital algorithm to realize modulation and demodulation.
