The above power wireless sensor network communication device based on the 5G-IoT technology can be further optimized or/and improved according to actual needs:
as shown in fig. 1 and 3, the MIMO on-chip dual-polarized integrated antenna is a multi-array antenna with a double-layer antenna structure, and includes an upper layer piece and a lower layer piece; the lower layer sheet is provided with a feed circuit, the feed circuit comprises a coupler, a power divider and an adjustable phase shifter, and the coupler and the adjustable phase shifter are connected with the power divider; the upper layer is provided with a radiation feed cavity.
In the technical scheme, the MIMO on-chip dual-polarization integrated antenna adopts a double-layer coupling technology of an on-chip antenna and integrated packaging, the upper layer sheet and the lower layer sheet both adopt silicon materials as bottom plates, and the MIMO on-chip dual-polarization integrated antenna has the characteristics of low cost, low power consumption, very low radiation efficiency and low resistivity of the silicon materials. The power divider in the lower layer sheet adjusts the frequency point and the phase of the feed circuit, and the coupler and the phase shifter can adjust the phase and the power value in a self-adaptive manner when the circuit structure of the power divider needs to be adjusted, so that the minimum loss of the feed circuit is ensured. The radiation feed cavity arranged on the upper layer sheet can be formed by a metalized aperture, the metalized aperture is formed by a plurality of regular gaps, and the size among the gaps directly influences the radiation direction and effect of an electromagnetic field, so that the square metal feed cavity can be selected to balance the radiation direction; therefore, radio frequency analog signals are radiated into free space from bottom to top, and independent beam forming can be formed. The characteristics of high gain, high bandwidth and the like of the antenna are formed by setting a proper waveguide integration gap distance and power amplifier parameters, and the access requirement of the sensor network is met.
As shown in fig. 1 and 4, the power divider is a 1-to-4 equal-division waveguide power divider, and includes 1 input port and 4 output ports, where the power values of the 4 output ports are equal, and the absolute value of the phase difference between every two output ports is 0, the 1 input port is disposed on the lower layer sheet, the 4 output ports are disposed on the upper layer sheet, and the radio frequency analog signal is radiated from the lower layer sheet to the upper layer sheet.
The power divider is a main device of a feed circuit, and an array structure formed by waveguide slits in the 1-in-4-equal-division waveguide power divider in the technical scheme can change a radio frequency signal excitation mode, and can adjust the direction and the phase, so that a radiation beam has a good radio frequency directional diagram. In order to obtain a good electric field distribution diagram of the antenna in a 60GHz high-frequency electric field environment, the gap distance formed by the waveguide metal columns can be set, so that the absolute values of the electric fields of the four output ports are equal, and the phase differences are opposite. As can be seen from fig. 4, the rf analog signal is input to Port1, and the output is output from Port2, Port3, Port4, and Port5 simultaneously, the impedance matching of the power divider can be optimized by adjusting the slot spacings m5 and m8, when the length of the slot spacing m2 is increased, the output power of Port3 becomes smaller and leads the phase, and the output power of Port2 increases and lags the phase, or vice versa; port Port3 varies as well as Port5, so it can be seen that varying the size of each slot changes the output power and phase values. Ensuring that m1 and m3 are equal at the corners can reduce the echo attenuation of the power divider, thereby minimizing the loss of the feed circuit. Specifically, the gap value of each slit is set as follows:
m1=m3=1mm，m2=m4=0.5mm，m5=2mm，m6=m7=0.5mm，m8=2.5mm；
the above formula shows that the slot spacing symmetry and the signal mapping rule are ensured as much as possible, the phase difference of the output ports is 180 degrees, the output power ratio is 1:1, and the return loss characteristics of the antenna are all below-6 dB.
As shown in fig. 1 and 5, the local oscillation filtering and frequency mixing module includes a frequency divider and multiple local oscillation filtering and frequency mixing circuits, each local oscillation filtering and frequency mixing circuit includes a frequency mixer, a first filter bank, a phase frequency detector, a second filter bank, and a de-noising oscillation circuit, the frequency mixer, the first filter bank, the phase frequency detector, the second filter bank, and the de-noising oscillation circuit are sequentially connected in series, and the frequency divider is connected with the frequency mixer of each local oscillation filtering and frequency mixing circuit.
Among the above-mentioned technical scheme, local oscillator filtering mixing module includes frequency divider and multichannel local oscillator filtering mixing circuit, every way local oscillator filtering mixing circuit operates independently, mutual noninterference, but reference frequency in the mixer sets up according to the power service demand, can the basic frequency point scope of automatic judgement business when the radio frequency analog signal inserts, thereby select suitable local oscillator passageway, the mixer superposes single radio frequency analog signal, the noise frequency of production is less, the time of local oscillator frequency source round trip switch has been saved, intermediate frequency front end processing procedure accelerates, and with frequency divider recursive control, single local oscillator filtering mixing circuit processing procedure is simple quick, the efficiency of moving of signal from high frequency to intermediate frequency signal promotes greatly. Each local oscillator filtering and mixing circuit adopts a frequency conversion mode, so that signal frequency points can be finely adjusted in real time, and the phase of signals can be corrected in time. Therefore, the multi-channel local oscillator filtering and mixing circuit and the parallel baseband processing flow can be perfectly butted, heterogeneous signals can be rapidly processed in completely independent channels, and the requirement of ubiquitous power Internet of things 5G service access is strongly supported.
As shown in fig. 1, the intermediate frequency and baseband unit includes an intermediate frequency processing module and a baseband processing module; the intermediate frequency processing module is used for converting intermediate frequency analog signals and intermediate frequency digital signals; the baseband processing module is used for obtaining, modulating and demodulating baseband digital signals, is provided with a layered tree-shaped time slot structure, and allocates time slots and channels for each signal.
In the above technical solution, the baseband processing module is used for implementing a series of processes of wireless signal transmission communication protocol, such as frame structure composition, modulation and demodulation, channel spreading, and the like, and cooperates with the intermediate frequency processing module to jointly complete processes of random access, channel mapping, and the like. When the intermediate frequency digital signal in the baseband processing module is subjected to baseband processing, due to the limitation of physical channel resources, the baseband processing module is provided with a layered tree-shaped time slot structure, idle time slot resources are fully utilized according to priority and requirements, a crowded frame state is improved, and 1 service is transmitted in each frame. That is, when a certain traffic frame in the previous time slot is congested with a plurality of traffic, in the frame structure that occupies the following time slot according to the priority order of the traffic, as shown in fig. 6, the traffic priorities are arranged in order, so to satisfy the congested traffic of frame 1, frame 4, and frame 6 in time slot 1, 2 time slots are needed for carrying, if there is only 1 idle time slot in the network at this time, it is indicated that the waiting time is to be reduced, and the collision traffic of frame 4 and frame 6 is to be re-accessed. However, the 5G channel resources are abundant, and the access requirements of the sensor network can be basically met.
The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and unnecessary technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
