Description

Technical Field

[0001] This application belongs to the technical field of radio frequency signal acquisition, and particularly relates to a radio frequency sampling and acquisition processing device and a radio frequency communication system. Background Technology

[0002] Currently, in the field of radio frequency communication, the heterodyne intermediate frequency sampling and receiving architecture is usually used to realize the transmission and reception of radio frequency signals. The heterodyne intermediate frequency sampling and receiving architecture is a signal processing method that combines superheterodyne receivers and digital sampling technology, and is widely used in fields such as communication radar and software radio.

[0003] In related technologies, the heterodyne intermediate frequency sampling and receiving architecture can specifically include a radio frequency front-end, a frequency conversion module, an intermediate frequency sampling and digital processing module, and a baseband processing module connected in sequence. In order to achieve high-frequency sampling, a mixer is usually set in the frequency conversion module to mix the received high-frequency radio frequency signal to generate an intermediate frequency signal, which facilitates the sampling of the radio frequency signal. However, the heterodyne intermediate frequency sampling and receiving architecture with a mixer requires a very complex radio frequency front-end, which in turn occupies a larger circuit board area and has a higher cost. Utility Model Content

[0013] The radio frequency sampling and acquisition processing device and radio frequency communication system of this application embodiment can, during the process of receiving and transmitting signals, firstly synchronize the clock of the controller and the radio frequency direct acquisition transceiver module through the clock module, then the signal conversion module receives the radio frequency signal and converts the radio frequency signal into a differential signal. At this time, the controller controls the radio frequency direct acquisition transceiver module to sample the differential signal to obtain a sampled radio frequency analog signal, and receives the sampled radio frequency analog signal to realize the reception of radio frequency signals. When transmitting a digital signal to be transmitted, the controller sends the digital signal to be transmitted to the radio frequency direct acquisition transceiver module. The radio frequency direct acquisition transceiver module converts the digital signal to be transmitted into a differential radio frequency analog signal, and converts the differential radio frequency analog signal into a radio frequency signal through the signal conversion module, and transmits the radio frequency signal. Compared with the heterodyne intermediate frequency sampling and receiving architecture in related technologies, this application can directly sample the differential signal through the integrated chip corresponding to the radio frequency direct acquisition transceiver module, which simplifies the radio frequency signal transmission chain, reduces the circuit board area, and reduces costs while ensuring a high sampling rate.

[0017] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0019] To facilitate understanding of this application, the background technology of this application will be introduced below.

[0020] Radio frequency (RF) communication systems are a very important part of modern electronic devices. The real world we live in is full of analog signals. To process and study these signals in engineering research, we need to use RF communication systems to convert analog signals into digital signals and store and process them. RF communication systems are the bridge connecting computers and the external physical world.

[0021] Currently, signal collection and transmission are typically achieved through radio frequency (RF) signals. The core components for RF signal acquisition and processing all use imported chips. Even domestically produced solutions employ a heterodyne intermediate frequency (IF) sampling and receiving architecture. In related technologies, the heterodyne IF sampling and receiving architecture can specifically include a radio frequency (RF) front-end, a frequency converter module, an IF sampling and digital processing module, and a baseband processing module connected in sequence. To achieve high-frequency sampling, a mixer is usually included in the frequency converter module to mix the received high-frequency RF signal and generate an IF signal, facilitating RF signal sampling. However, using a heterodyne IF sampling and receiving architecture that includes a mixer requires a highly complex RF front-end, resulting in a larger circuit board area and higher cost.

[0022] To address the problems of the prior art, this application provides a radio frequency sampling and acquisition processing device and a radio frequency communication system. The radio frequency sampling and acquisition processing device will be described first.

[0023] Figure 1 This is a structural block diagram illustrating a radio frequency sampling and acquisition processing apparatus provided in one embodiment of this application, as shown below. Figure 1 As shown, the radio frequency sampling and acquisition processing device may include: Signal conversion module 1 is used to convert between radio frequency signals and differential signals; The radio frequency direct sampling transceiver module 2 is connected to the signal conversion module 1 and is used to sample the differential signal generated by the signal conversion module 1 to obtain a sampled radio frequency analog signal, and / or to convert the digital signal to be transmitted into a differential radio frequency analog signal; The controller 3 is connected to the RF direct acquisition transceiver module 2 and is used to receive sampled RF analog signals and / or send digital signals to be transmitted to the RF direct acquisition transceiver module 2. Clock module 4 is connected to controller 3 and RF direct acquisition transceiver module 2 respectively, and is used to provide reference clock signals for controller 3 and RF direct acquisition transceiver module 2 so that controller 3 and RF direct acquisition transceiver module 2 keep clock synchronized.

[0024] In this embodiment, during the signal reception and transmission process, the clock module 4 first synchronizes the clocks of the controller 3 and the RF direct sampling transceiver module 2. Then, the signal conversion module 1 receives the RF signal and converts it into a differential signal. At this time, the controller 3 controls the RF direct sampling transceiver module 2 to sample the differential signal to obtain a sampled RF analog signal and receives the sampled RF analog signal to achieve RF signal reception. When transmitting a digital signal to be transmitted, the controller 3 sends the digital signal to be transmitted to the RF direct sampling transceiver module 2. The RF direct sampling transceiver module 2 converts the digital signal to be transmitted into a differential RF analog signal and converts the differential RF analog signal into an RF signal through the signal conversion module 1, and then transmits the RF signal. Compared with the heterodyne intermediate frequency sampling and receiving architecture in related technologies, this application can directly sample the differential signal through the integrated chip corresponding to the RF direct sampling transceiver module 2. While ensuring a high sampling rate, it simplifies the RF signal transmission chain, reduces the circuit board area, and lowers the cost.

[0025] See Figure 2 In some specific embodiments, the signal conversion module 1 may include at least one first signal conversion module 11 and at least one second signal conversion module 12, wherein the first signal conversion module 11 is used to convert a single-ended radio frequency signal into a differential radio frequency analog signal, and the second signal conversion module 12 is used to convert the differential radio frequency analog signal into a single-ended radio frequency signal.

[0026] RF direct acquisition transceiver module 2 may include: At least one analog-to-digital converter 21, the input terminal of the analog-to-digital converter 21 is connected to the corresponding first signal conversion module 11, and the output terminal of the analog-to-digital converter 21 is connected to the controller 3; At least one digital-to-analog converter 22 is provided. The input terminal of the digital-to-analog converter 22 is connected to the signal output terminal of the controller 3, and the output terminal of the digital-to-analog converter 22 is connected to the corresponding second signal conversion module 12.

[0027] In this embodiment, the first signal conversion module 11 and the second signal conversion module 12 can be baluns, used to convert between single-ended signals and differential signals.

[0028] Specifically, as an example, the radio frequency sampling and acquisition processing device provided in the embodiments of this application will be described below using two first signal conversion modules 11, two second signal conversion modules 12, two analog-to-digital converters 21 and two digital-to-analog converters 22 as examples.

[0029] It is worth noting that at least one analog-to-digital converter 21 can share the same first signal conversion module 11, or they can be set one-to-one. The number of first signal conversion modules 11 can also be redundantly set. Correspondingly, the number of second signal conversion modules 12, analog-to-digital converters 21 and digital-to-analog converters 22 can be set according to the actual scenario, and are not limited here.

[0030] In this embodiment, the specific connection method of the first signal conversion module 11 is described in [reference needed]. Figure 3 Among them, the optional model of the balun T4 is TCM1-63AX+, and the optional model of the RF signal receiver is JOHNSON142-0701-851.

[0031] In other embodiments, the specific connection method of the second signal conversion module 12 can be found in [reference needed]. Figure 4 Among them, the optional model of the first chip U271 of the second signal conversion module 12 is TCM2-63WX. Figure 4 The specific circuit connection structure is the classic peripheral circuit of the second signal conversion module 12, which will not be described in detail here.

[0032] In the above embodiments, the first signal conversion module 11 converts the received single-ended radio frequency signal into a differential radio frequency analog signal. Then, the analog-to-digital converter 21 samples the differential radio frequency analog signal and transmits the sampled differential radio frequency analog signal to the controller 3 to realize the reception of radio frequency signals. Correspondingly, when the radio frequency sampling and acquisition processing device provided in this application embodiment sends radio frequency signals to the outside, the controller 3 sends the digital signal to be transmitted to the digital-to-analog converter 22. The digital-to-analog converter 22 synthesizes a specific broadband differential radio frequency analog signal according to the received digital signal to be transmitted. Then, the differential radio frequency analog signal is converted into a single-ended radio frequency signal by the second signal conversion module 12 and then sent.

[0033] In one specific embodiment, a schematic diagram of the specific circuit connection structure of the RF direct acquisition and transceiver module 2 is shown below. Figure 5 As shown, the optional model of the second chip U31 of the RF direct acquisition transceiver module 2 can be CX8242KA. In this embodiment, the second chip U31 can mix the high-frequency RF signal into an intermediate frequency differential signal. At the same time, the chip is equipped with an analog-to-digital converter 21 and a digital-to-analog converter 22. After the mixing is completed, the second chip can directly perform sampling without the need for additional electronic components such as mixers. Only the second chip U31 needs to be set, which can reduce the area occupied on the circuit board and thus reduce the cost of the RF sampling acquisition and processing device.

[0034] In some embodiments, controller 3 may include: The controller 3 is connected to the analog-to-digital converter 21 through the first communication interface 31. The controller 3 is connected to the digital-to-analog converter 22 via the second communication interface 32. The controller 3 can be used to configure the working mode of the analog-to-digital converter 21 and obtain the working status of the analog-to-digital converter 21 through the first communication interface 31; the controller 3 can also be used to configure the working mode of the digital-to-analog converter 22 and obtain the working status of the digital-to-analog converter 22 through the second communication interface 32.

[0035] In this embodiment, the operating modes of the analog-to-digital converter 21 may include timed operation, untimed operation, and sleep mode, and the operating states of the analog-to-digital converter 21 may include running state, alarm state, sleep state, and standby state; the operating modes of the digital-to-analog converter 22 may include timed operation, untimed operation, and sleep mode, and the operating states of the digital-to-analog converter 22 may include running state, alarm state, sleep state, and standby state.

[0036] In some other embodiments, the clock module 4 can receive an external reference clock and distribute the external reference clock to the RF direct acquisition transceiver module 2 and the controller 3 respectively through the broadband frequency synthesizer and clock distributor built into the clock module 4, so as to provide a reference clock signal for the RF direct acquisition transceiver module 2 and the controller 3, so that the controller 3 and the RF direct acquisition transceiver module 2 can maintain clock synchronization.

[0037] As an example, both the first communication interface 31 and the second communication interface 32 can be 4-wire JESD204B interfaces, or they can be optical communication interfaces, which are not limited here.

[0039] In this embodiment, the digital signal communication data can be the digital signal data corresponding to the differential radio frequency analog signal after the radio frequency signal conversion, or it can be the digital signal to be transmitted.

[0040] Specifically, after receiving the digital signal data converted from the differential analog signal or the digital signal to be transmitted, the controller 3 can buffer and store the digital signal data or the digital signal to be transmitted in the storage module 5 to ensure the traceability and backup of the digital signal data.

[0041] In some other embodiments, the radio frequency sampling and acquisition processing apparatus further includes: The first transmission interface 6 is connected to the controller 3; The first transmission interface 6 is used to transmit digital signal communication data received or sent by the controller 3.

[0043] Specifically, the first transmission interface 6 may include: The protocol conversion module is connected to the controller 3 at its input terminal. The protocol conversion module is used to perform photoelectric protocol conversion on digital signal communication data. The transmitting and receiving module has its first end connected to the output of the protocol conversion module, and its second end connected to an external device.

[0044] In this embodiment, during the process of sending the digital signal data corresponding to the radio frequency signal received by the controller 3 to the external device, the digital signal data can first be converted into photoelectric protocol, that is, the digital signal data can be converted into optical signal data or electrical signal data. Then, the digital signal communication data is sent to the external device through the communication interface corresponding to the transmitting and receiving module.

[0045] Correspondingly, the transmit / receive module can receive the digital signal to be transmitted in optical or electrical form from the external device, and the data can be converted by the protocol conversion module so that the controller 3 can receive the digital signal to be transmitted provided by the external device.

[0046] In some embodiments, the radio frequency sampling and acquisition processing apparatus may further include: Processor 7 is connected to controller 3; The processor 7 is used to monitor the status of the controller 3 and obtain status monitoring information.

[0048] Specifically, the processor 7 can monitor the operating status of the controller 3 in a timely manner so that after the controller 3 fails, the processor 7 can understand the fault status of the controller 3 in a timely manner so that the user can repair the controller 3 in a timely manner. The status monitoring information can also include normal operation information and test status information. That is, normal operation information can indicate that the controller 3 is operating normally, and test status information can indicate that the processor 7 is testing the controller 3.

[0049] In addition, in some embodiments, a watchdog program may be configured in the processor 7 to accurately monitor the fault status of the controller 3, so as to ensure that the fault information of the controller 3 can be accurately and timely monitored.

[0050] In other embodiments, to ensure that users can promptly understand the operating status of controller 3, the radio frequency sampling and acquisition processing device may further include: The second transmission interface 8 has an input terminal connected to the processor 7 and an output terminal connected to an external host computer. The second transmission interface 8 is used to transmit the status monitoring information of the processor 7 to the controller 3 to an external host computer.

[0051] Specifically, the second transmission interface 8 can be configured with at least one of a Bluetooth module, a Wi-Fi module, or a network module to enable communication between the processor 7 and an external host computer.

[0052] In this embodiment, the processor 7 can report the control and status monitoring information of the controller 3 to an external host computer through the second transmission interface 8, so that it can be displayed on the display screen of the external host computer, so that the staff can connect to the control status of the controller 3 in a timely manner.
