[0033] In order to make the objectives, technical solutions and advantages of the present disclosure more apparent, the following will describe example embodiments according to the present disclosure in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited by the example embodiments described herein.

[0034] At present, the existing positioning scheme is to use Application-Specific Integrated Circuit (ASIC) for positioning. But the ASIC chip is a chip specially designed for a certain function or application field, and its customization strength is high and flexibility is poor. Thus, it is easy to cause the problems of high cost, poor flexibility and single application scene of the existing positioning scheme, which cannot meet the actual objective needs.

[0035] Therefore, the present disclosure proposes a positioning method which can utilize the reconfigurability and flexibility of Software Defined Radio (SDR) hardware, combine the functions of receiving and transmitting signals of an antenna module, and flexibly change the characteristics of signals according to actual needs under the coordination of a software control module, so as to realize target terminal positioning in different types of signals and different scenes. First of all, please refer to Figure 1 , Figure 1 The present disclosure provides a schematic diagram of the architecture of a positioning system. As shown in Figure 1 , the positioning system at least includes a software control module, SDR hardware and an antenna module.

[0036] Specifically, the software control module can be understood as a control module of the entire positioning system. It can be a functional unit running based on a software program, which is mainly responsible for at least one of overall planning, coordination and management of the entire positioning process, and intelligent operation related to signal processing.

[0037] The SDR hardware can be understood as a radio hardware with high reconfigurability and versatility. The core reconfigurable signal processor is the key to the flexibility of the SDR hardware. It can quickly realize different radio functions by reconfiguring the internal circuit structure and parameters according to the instructions of the software control module, such as setting it as a mode of transmitting a first signal with a specific frequency and modulation method, and then switching it to a mode of receiving and processing a second signal with a specific format, just like a hardware that can quickly change shape and function according to different task requirements.

[0038] The antenna module can realize the interactive communication of signals with external devices, and it can reasonably select and transmit and receive the preferred signals according to different positioning scenes and system requirements.

[0039] The present disclosure does not limit the specific structure and form of the software control module, SDR hardware and antenna module, which can be adjusted as needed. More detailed structures will be described in detail in the following embodiments.

[0040] Next, Figure 2 The present disclosure provides a flowchart of a positioning method. As shown in Figure 1As shown, the positioning method is applied to a software control module of a positioning system, and the method comprises:

[0041] In step S201, a first signal is sent out by the SDR hardware and the antenna module; the first signal is used to request a terminal to report first information.

[0042] In the present disclosure, the first signal can be understood as an instructive signal configured by the software control module based on positioning requirements and sent out by the SDR hardware and the antenna module, and the purpose is to request the first information of at least one terminal. In the embodiment of the present disclosure, the first signal can be a radio frequency signal. The radio frequency signal has the characteristic of being able to effectively propagate in space, and the frequency range can be flexibly selected according to the specific positioning scene and the characteristics of the terminal.

[0043] In the present disclosure, the first information can be understood as information related to the position of the terminal fed back to the software control module. The specific form of the first information is not limited here, and will be described below in conjunction with the embodiments.

[0044] Specifically, in the embodiment of the present disclosure, if the positioning of the target terminal is to be achieved, the software control module can send the first signal out by using the SDR hardware and the antenna module. The sending method includes but is not limited to at least one of the following: frequency band selection sending, coverage range selection sending. The frequency band selection sending can be understood as sending the first signal according to a preset frequency band or a preset frequency band range. The coverage range selection sending can be understood as sending the first signal within a preset coverage range or coverage distance. In this way, the first signal can be accurately and efficiently transmitted to the terminal.

[0045] Further, in this process, the software control module can also consider at least one of the following factors: the model of the terminal, the surrounding electromagnetic environment, etc., and flexibly adjust at least one of the following: the frequency, power, modulation mode and coding format of the first signal, to obtain the most suitable signal form for the current environment and the terminal, so that the terminal can efficiently and accurately obtain the first signal.

[0046] In step S202, a second signal is received by the antenna module and the SDR hardware.

[0047] In step S203, the target terminal is positioned based on the second signal.

[0048] In the present disclosure, the second signal can be understood as a feedback signal related to the position of the terminal determined based on the first signal. In the embodiment of the present disclosure, the second signal can be a digital baseband signal, which can facilitate the software control module to process the second signal and obtain the accurate position information of the terminal.

[0049] Specifically, in the embodiments of the present disclosure, the software control module can control the antenna module to receive the second signal of at least one terminal by the SDR hardware. In this process, the software control module can detect the state of the receiving link, and once the feedback signal of the terminal is found, the second signal can be received. After the software control module receives the second signal, the second signal can be analyzed to obtain the position information of the terminal corresponding to the second signal, and then the positioning of the target terminal is realized. This can be obtained by at least one of signal demodulation, signal extraction, positioning calculation, etc., which will be described in detail below.

[0050] In summary, the technical solution provided by the present disclosure can utilize the reconfigurability and flexibility of the SDR hardware, combine the functions of the antenna module for receiving and transmitting signals, and flexibly change the characteristics of the signals according to actual needs under the coordination of the software control module, so as to realize the positioning of the target terminal in different types of signals and different scenarios, avoiding the problem that the existing ASIC chip has fixed functions and can only be used for specific design purposes. At the same time, this combination of general software control and SDR hardware avoids the limitations caused by high customization of existing ASIC chips, reducing the cost of the positioning system. In this way, the cost of positioning can be reduced, the flexibility can be improved, various scenarios can be coped with, and the actual objective needs can be met.

[0051] As described above, the first information can be understood as the information related to the position of the terminal fed back to the software control module, and the content of the first information will be described in detail as follows:

[0052] The first information of the present disclosure can include at least one of the following: International Mobile Subscriber Identity (IMSI), power value.

[0053] In the present disclosure, IMSI can uniquely represent terminal user information worldwide, which enables the software control module to accurately identify the information fed back by the terminal corresponding to the terminal user after receiving the IMSI as the first message, and then use the feedback information for positioning.

[0054] In the present disclosure, the power value reflects the transmission power of the terminal when it feeds back. After the software control module receives the power value, it can further accurately analyze the position of the terminal in combination with other related data. For example, by using a known signal propagation model, combining the actual signal strength of the feedback signal of the terminal received at the receiving end, and using the relationship between the two and the power value, the distance relationship between the terminal and the positioning system can be more accurately calculated.

[0055] The following specifically describes how the software control module of the present disclosure sends the first signal outwardly, at which time the method comprises:

[0056] sending a third signal to the SDR hardware;

[0057] The SDR hardware is configured to convert the third signal into the first signal, and the antenna module is configured to send the first signal outwardly.

[0058] In the present disclosure, in order to achieve accurate positioning of the target terminal, the software control module can control the sending of the first signal outwardly, and in order to enable the first signal to be well propagated in a complex and variable scene, the first signal can be a radio frequency signal, because the radio frequency signal has the characteristics of long-distance transmission in space and strong penetration ability of obstacles. Specifically, in the process of sending the radio frequency signal, the sending of the radio frequency signal can be achieved with the aid of the third signal. The third signal can be a digital baseband signal. This is because the digital baseband signal has the characteristics of strong anti-interference ability, easy processing and integration. It can resist electromagnetic interference in complex scenes through digital coding technology, and can be flexibly adjusted by using digital signal processing. The signal parameters can also be seamlessly connected with the software control module in the system. The software control module can conveniently modulate, encode, power adjust, and at least one operation of the digital baseband signal according to the characteristics of the target terminal, and send it to the SDR hardware. This can improve the accuracy of radio frequency signal transmission, enhance the adaptability and flexibility of the positioning system, and improve the accuracy and efficiency of positioning.

[0059] Specifically, in the embodiments of the present disclosure, the software control module can send the third signal (i.e., the digital baseband signal) to the SDR hardware, the SDR hardware converts the third signal into the first signal (i.e., the radio frequency signal), and the antenna module sends the first signal (i.e., the radio frequency signal) outwardly, thereby laying a foundation for subsequent accurate positioning of the target terminal.

[0060] The following specifically describes the method of receiving the second signal by the software control unit of the present disclosure, comprising:

[0061] receiving the second signal of the SDR hardware;

[0062] The antenna module is configured to receive a fourth signal, and the SDR hardware is configured to convert the fourth signal into the second signal.

[0063] In the present disclosure, in order to realize the accurate positioning of the target terminal, the software control module needs to accurately receive the second signal to obtain the key information fed back by the terminal. In the complex and changeable communication environment, the receiving process needs to be reliable and efficient. Therefore, the second signal can be a digital baseband signal. In the receiving process, the fourth signal can be used to realize the reception of the second signal. The fourth signal can be a radio frequency signal. This is because the radio frequency signal has the characteristics of long-distance transmission in space and strong penetration ability of obstacles. It can effectively propagate in a complex scene by using its frequency band characteristics, and can be efficiently received by the antenna module. After receiving the fourth signal, the antenna module transmits it to the SDR hardware. The SDR hardware converts the fourth signal (radio frequency signal) into the second signal (digital baseband signal). The software control module can conveniently receive the second signal from the SDR hardware and obtain terminal position information and other data according to the content, thereby providing a basis for the accurate positioning of the target terminal. In this way, the accuracy of the second signal reception can be improved, the adaptability of the positioning system to complex receiving environments can be enhanced, and the reliability and efficiency of the entire positioning process can be improved.

[0064] Specifically, in the embodiment of the present disclosure, the antenna module receives the fourth signal (i.e. radio frequency signal), the SDR hardware converts the fourth signal into the second signal (i.e. digital baseband signal), and the software control module receives the second signal (i.e. digital baseband signal) of the SDR hardware, thereby laying a foundation for the subsequent accurate positioning of the target terminal.

[0065] In the following, how the software control module of the present disclosure performs positioning of the target terminal will be specifically described. The present disclosure specifically provides two methods, which can be:

[0066] The first method includes:

[0067] Based on the second signal, the first information is determined.

[0068] When the first information is a power value, the power values in different directions are compared to position the target terminal.

[0069] In an embodiment of the present disclosure, the software control module can perform analysis and processing on the received second signal to extract relevant data information to determine the first information. When it is detected that the first information is a power value, the software control module will compare and analyze the power values received in different directions in detail to determine the positioning of the target terminal.

[0070] Specifically, the software control module can compare the power values in different directions, and the region pointed to by the direction with the largest power value can be determined as the range where the target terminal is most likely located. The software control module can also compare the difference between the power values in different directions and a preset power threshold, and further analyze the position information of the target terminal according to the size and sign of the difference. If the difference between the power value in a direction and the power threshold is positive and small, it indicates that the target terminal is more likely to exist in this direction and is closer. If the difference is negative and large, it indicates that this direction is less likely to be the direction of the target terminal, and factors such as severe obstruction may have severely weakened the signal power. In this way, the position of the target terminal is more accurately determined by analyzing the difference in each direction. The specific comparison is not limited in detail here.

[0071] The second method includes:

[0072] When the first information is an IMSI, the IMSI is matched with a target IMSI to determine the target terminal;

[0073] The fifth signal is sent to the target terminal; the fifth signal is used to request the second information;

[0074] The target terminal is positioned based on the second information.

[0075] In another embodiment of the present disclosure, the software control module can analyze and process the received second signal to obtain the first information. When the analyzed first information is an IMSI, it can be matched with a target IMSI to obtain the target terminal. Further, the software control module needs to send a fifth signal to the target terminal, and the fifth signal can be understood as a request signal for requesting the second information from the target terminal, while the second signal can be understood as specific data provided by the target terminal to assist positioning. Then, the software control unit receives the second information and positions the target terminal based on the second signal.

[0076] Specifically, after receiving the first information and identifying that it is an IMSI, the software control module can match the received IMSI with the pre-stored target IMSI. Once the received IMSI that completely matches the target IMSI is found, the terminal corresponding to the received IMSI can be determined as the target terminal. Then, the software control module can send a fifth signal to the target terminal that has been determined. The fifth signal can be used to request the second information of the target terminal. The second information can be understood as specific data sent by the target terminal to assist positioning after the target terminal is determined. Finally, after receiving the second information, the software control module analyzes and utilizes different types of second information and their corresponding positioning methods to calculate the position of the target terminal.

[0077] The second information of the present disclosure can include, but is not limited to, at least one of the following: signal field strength value, signal propagation delay. The signal field strength value can be understood as a quantitative representation of the electromagnetic signal strength received from a specific signal source (such as a signal sent by a positioning system) at the location of the target terminal. It reflects the energy attenuation of the signal during the process of propagating from the signal source to the target terminal. The signal field strength value can be used to assist in determining the position of the target terminal according to the adopted signal propagation model (such as at least one of the free space propagation model, the logarithmic distance path loss model, etc.) or comparison, etc. The signal propagation delay can be understood as the time interval experienced by the signal from the transmitting end, through space propagation, to the receiving end. The signal propagation delay can be used to assist in determining the position of the target terminal according to the multiple reference points set in the positioning system or comparison.

[0078] In the following, the software control module of the present disclosure will be specifically described as to how to use the second information to determine the position of the target terminal. At this time, the method can include, but is not limited to, at least one of the following:

[0079] Comparing the second information to determine the position of the target terminal;

[0080] Inputting the second information into a preset model to determine the position of the target terminal.

[0081] In an embodiment of the present disclosure, when the software control module obtains the second information, it can determine the position of the target terminal by comparing the second information. Specifically, the signal field strength value is inversely proportional to the square of the distance. When the second information is the signal field strength value, the software control module can compare the signal field strength values of the target terminal received at different positions by using this relationship. According to the difference in signal field strength values, the relative distance of the target terminal to the receiving point can be roughly inferred. For example, the direction with a larger field strength value means that the target terminal is closer to the receiving point in that direction. For the signal propagation delay, the position information of the target terminal can be determined by comparing the signal propagation delay data received from multiple reference points. Since the distances from different reference points to the target terminal are different, the signal propagation delays are also different. By comparing the sizes and differences of these delays, the relative position of the target terminal to each reference point can be preliminarily judged. For example, the reference point with shorter propagation delay is closer to the target terminal.

[0082] In another embodiment of the present disclosure, when the software control module obtains the second information, the positioning of the target terminal can be determined by inputting a preset model. Specifically, when the second information contains a signal field strength value, it is substituted into a suitable signal propagation model together with a known signal transmission power to accurately calculate the positioning of the target terminal. The signal transmission model can include, but is not limited to, at least one of the following: a log distance path loss model, a free space positioning model. When the second information contains signal propagation delay, according to the known signal propagation speed, the signal propagation delay data received by each reference point is input into the positioning model to accurately determine the positioning of the target terminal.

[0083] In summary, the second method of the software control module for positioning the target terminal is described, which can more flexibly and accurately determine the position of the target terminal in different environmental conditions and application scenarios.

[0084] In an exemplary embodiment, Figure 3 A complete flowchart for positioning the target terminal is provided for the embodiments of the present disclosure. From Figure 3 As can be seen, the entire positioning process includes:

[0085] S1, the public security client determines the target feature code IMSI (which is equivalent to the target IMSI of the present disclosure) according to the research and judgment system, and imports the IMSI through the mobile phone monitoring software (which is equivalent to the software control module of the present disclosure).

[0086] S2, the mobile phone monitoring software generates upper layer signaling in combination with a general purpose computer and encodes and modulates it into a digital baseband signal (which is equivalent to the third signal of the present disclosure).

[0087] S3, the digital baseband signal is sent to the SDR hardware (which is equivalent to the SDR hardware of the present disclosure) through SDR hardware driving and high-speed USB / high-speed network.

[0088] S4, the FPGA in the SDR hardware drives the radio frequency ADC to convert the digital baseband signal into a radio frequency signal (which is equivalent to the first signal of the present disclosure) and sends it to the power amplifier, combiner and antenna.

[0089] It should be noted that the process of steps S1-S4 is equivalent to the process of the software control module of the present disclosure controlling the SDR hardware and the antenna module to send the first signal. The power amplifier, combiner and antenna in the above S4 are equivalent to the antenna module of the present disclosure.

[0090] S5, the mobile phone receives the wireless signal transmitted by the portable positioning device (which is equivalent to the positioning system of the present disclosure) and switches and camps to the wireless signal. The mobile phone monitoring software requires the target mobile phone (which is equivalent to the target terminal of the present disclosure) to report the IMSI through software signaling.

[0091] S6, the SDR module transmits the acquired IMSI (equivalent to the second signal of the present disclosure) to the mobile phone monitoring software, and the mobile phone monitoring software performs target list matching on the IMSI. If it is a target IMSI, the target mobile phone is required to report the uplink power value. At the same time, the operator determines the direction of the power value reported by the target mobile phone from different directions, thereby determining the approximate direction of the target.

[0092] It should be noted that S5-S6 is the process of receiving the second signal and determining the target terminal positioning of the software control module of the present disclosure.

[0093] In other words, the above process can be understood as follows: the portable positioning device (equivalent to the positioning system of the present disclosure) needs to pre-input the target IMSI (equivalent to the IMSI of the target terminal of the present disclosure) number when starting, and then locate the target through the APP one-key positioning function. The mobile phone monitoring and positioning software (equivalent to the software control module of the present disclosure) will first induce (equivalent to the first signal of the present disclosure) the mobile phone signal in the coverage range of the portable positioning device, adsorb and acquire the IMSI, and match the adsorbed and collected IMSI (equivalent to the second signal of the present disclosure) with the target IMSI. If the APP is hit, an alarm prompt sound will be issued, and the APP will acquire the target mobile phone signal strength value (equivalent to the second information of the present disclosure) through the mobile phone monitoring and positioning software. The field strength value is inversely proportional to the distance of the target mobile phone, and the larger the field strength value, the closer the target mobile phone is to the portable positioning device. The APP will indicate the direction according to the field strength value of the target mobile phone in different directions. After the target IMSI is hit, the user needs to rotate the portable positioning device 360 degrees in place, and the APP can display the field strength values in different directions, thereby helping the user to determine the approximate direction of the target mobile phone more clearly.

[0094] The present disclosure also provides a positioning method applied to a positioning system comprising a software control module, an SDR hardware and an antenna module, the method comprising:

[0095] The software control module sends a third signal to the SDR hardware;

[0096] The SDR hardware converts the third signal into a first signal;

[0097] The antenna module sends the first signal;

[0098] The antenna module receives a fourth signal;

[0099] The SDR hardware converts the fourth signal into a second signal;

[0100] The software control module locates a target terminal based on the second signal.

[0101] In the present disclosure, when positioning, the positioning system can first send a third signal to the SDR hardware by means of the software control module, and then the SDR hardware converts the third signal into a first signal. The antenna module will send the determined first signal to at least one terminal. At the same time, the antenna module will also receive the fourth signal sent by at least the terminal. The SDR hardware converts the fourth signal into a second signal. The software control can realize the positioning of the terminal based on the second signal, which can be referred to in the above, and will not be repeated here.

[0102] In an exemplary embodiment, the entire positioning process can be: the mobile phone monitoring and positioning software (equivalent to the software control module of the present disclosure) changes the system function into a mobile phone monitoring and positioning device when the mobile phone monitoring and positioning function is needed, generates wireless communication base station upper signaling and encodes and modulates it into a digital baseband signal (equivalent to the third signal of the present disclosure), sends the digital baseband signal to the SDR hardware, the SDR hardware converts the digital baseband signal into an RF signal (equivalent to the first signal) and sends it to the antenna, and then transmits it to the air through the antenna and is received by the nearby mobile phone. The RF signal (equivalent to the fourth signal) transmitted by the mobile phone is received by the SDR hardware through the antenna of the portable positioning device and is converted into a digital baseband signal (equivalent to the second signal) after analog-to-digital conversion, and then it is driven by the SDR hardware and transmitted to the mobile phone monitoring and positioning software. The mobile phone monitoring and positioning software demodulates and decodes the digital baseband signal into upper signaling and obtains the IMSI (equivalent to the first information) from the specified signaling.

[0103] The present disclosure also provides a specific positioning system structure, which comprises:

[0104] The software control module is used to execute the method of any one of the above embodiments;

[0105] The SDR hardware is used to realize the conversion between the digital baseband signal and the RF signal;

[0106] The antenna module is used to transmit or receive the RF signal.

[0107] In the present disclosure, the system comprises a software control module, SDR hardware, and an antenna module, which can also be understood as the above-mentioned Figure 1The positioning system will be described in more detail. The SDR hardware is mainly used to realize the conversion between digital baseband signals and radio frequency signals. In the signal sending stage, the SDR hardware receives the digital baseband signals sent by the software control module, and converts them into radio frequency signals suitable for propagation in space. In the signal receiving stage, the SDR hardware can also convert the radio frequency signals received by the antenna module into digital baseband signals in reverse, providing convenience for the subsequent processing of the software control module. The antenna module is mainly responsible for the transmission and reception of radio frequency signals. In terms of transmission, it radiates the radio frequency signals converted by the SDR hardware to space in a specific direction and power, to ensure that the signal can effectively cover the target area, so that the terminal can receive the positioning signal. In terms of reception, the antenna module can sensitively capture the radio frequency signals from the direction of the target terminal.

[0108] The software control module of the present disclosure can be a general software control module, which can include but is not limited to at least one of the following: X86 architecture processor, Advanced RISC Machines (ARM) architecture processor. Among them, X86 is a complex instruction set computer (CISC) architecture, which has strong processing capability. X86 can efficiently run complex operating systems and large software applications. In the present system, it can quickly process various positioning algorithms. ARM can provide high-performance, low-power processing solutions, making it more prominent in handling some relatively simple but highly real-time tasks.

[0109] The SDR hardware of the present disclosure can include:

[0110] The transceiver is used for communication with the software control module;

[0111] The field programmable gate array (FPGA) is used to control the transceiver and the universal radio frequency analog-to-digital converter (ADC);

[0112] The ADC is used to realize the conversion between digital baseband signals and radio frequency signals.

[0113] In the present disclosure, the transceiver in the SDR hardware undertakes the important responsibility of communicating with the software control module. The transceiver of the present disclosure can be a high-speed universal serial bus (USB) / high-speed network interface, or other high-speed communication interfaces. The field-programmable gate array (FPGA) of the present disclosure can effectively control the transceiver and the universal radio frequency analog-to-digital converter (ADC). For the transceiver, the FPGA can set the working parameters of the transceiver according to different application scenarios and positioning requirements. For the ADC, the FPGA can coordinate the working process of the ADC. The ADC of the present disclosure is a key component for realizing the mutual conversion between the digital baseband signal and the radio frequency signal. In the signal sending stage, it can convert the digital baseband signal from the software control module into a radio frequency signal suitable for propagation in space. In the signal receiving stage, the ADC can convert the radio frequency signal received by the antenna module back into a digital baseband signal, so that the subsequent software control module can process and analyze it.

[0114] The antenna module of the present disclosure can include:

[0115] a power amplifier for realizing power amplification of the radio frequency signal;

[0116] a combining module for realizing the combination of multiple signals or the splitting of a single signal;

[0117] an antenna for realizing the sending or receiving of the radio frequency signal.

[0118] In the present disclosure, the power amplifier can improve the power level of the radio frequency signal through specific circuit design and working principle, so that it has enough energy to propagate in space after being sent out. The combining module can combine multiple signals into one signal according to certain rules and technical means when there are multiple different radio frequency signals that need to be processed at the same time, so as to be sent uniformly through the antenna subsequently. Conversely, when a composite signal containing multiple information is received, it can be split into single signals for at least one operation such as analysis, processing or forwarding. The antenna is an important component for realizing the sending or receiving of the radio frequency signal. It can realize the mutual conversion between the electrical signal and the electromagnetic wave. In the sending end, the antenna converts the radio frequency signal into the electromagnetic wave form and radiates it into space. In the receiving end, the antenna can capture the radio frequency signal transmitted from space and convert it into the electrical signal form, so as to be transmitted to other components (such as SDR hardware) in the antenna module for analysis, processing and interpretation, and then realize related functions such as positioning.

The SDR hardware module mainly includes a USB3.0 or above or 10Gbps or above network transceiver, an FPGA, and a general-purpose radio frequency ADC. The USB3.0 is mainly used to connect the general-purpose computer, so that it can control the SDR module; the FPGA is used for logic circuit design in the SDR hardware module; the general-purpose radio frequency ADC is used for conversion between analog signals and digital signals.
