[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0023] Refer to Figure 1 , which shows a structural schematic diagram of an embodiment of an intelligent terminal security monitoring system of the present invention. The intelligent terminal security monitoring system includes: an intelligent security terminal 101 and a host computer 102. The intelligent security terminal 101 receives the acquisition instruction sent by the host computer 102 and acquires security information according to the acquisition instruction. The security information includes at least video data, magnetic force data, and position data, and sends the security information to the host computer.

[0024] The host computer 102 is used to parse the received security information and process the parsed data information to obtain the status information of the intelligent security terminal.

[0025] Specifically, in the embodiment of the present invention, the intelligent terminal security monitoring system includes multiple host computers 102. Each host computer 102 can also be connected to multiple intelligent security terminals. Each intelligent security terminal can be placed at each monitoring point. Each intelligent security terminal and the host computer can be remotely connected and can be connected through WiFi or Bluetooth.

[0026] If you want to obtain the magnetic force condition of a certain monitoring point, the host computer sends a collection instruction to the intelligent safety terminal of the monitoring point. The intelligent safety terminal can obtain the safety information of the monitoring point. For example, the magnetic force data of the monitoring point, the video data of the monitoring point, and the position data of the monitoring point, such as the longitude and latitude information of the monitoring point. Then the intelligent safety terminal sends the collected safety information to the host computer;

[0027] The host computer receives the safety information sent by each intelligent safety terminal, stores the intelligent safety terminal identifier and the corresponding safety information, saves the parsed data locally according to the format, and respectively parses and processes the magnetic force data and the video data to obtain the status information of the intelligent safety terminal, and can view the video data and the magnetic force data through software to achieve data visualization.

[0028] Specifically, after the host computer obtains the safety information, for example, after obtaining the magnetic force data, it performs a hierarchical intelligent filtering algorithm on the magnetic force data;

[0029] The hierarchical intelligent filtering algorithm is specifically the programming of the hierarchical intelligent Gaussian algorithm: after the data is converted by the AD converter, it is converted into a floating-point number from +1000000.00 to -1000000.00 after scale transformation, and the precision retains multiple decimal places. The data is filtered by a hierarchical filtering algorithm to separate noise and the background magnetic field, remove interference, and retain the true value for calculating the accurate position of the target body.

[0030] The hierarchical intelligent filtering algorithm is as follows: Wavefront preprocessing: The acquisition interval is set to 200 milliseconds, 50 groups of data are continuously acquired and stored, the data is sorted by numerical size, 5 groups of MAX and 5 groups of MIN are removed, and the average value of the remaining 40 groups of data is obtained to get the preprocessed value.

[0031] The principle of the hierarchical intelligent Gaussian filtering algorithm specifically includes:

[0032] 1) Collect the first group of data and keep it;

[0033] 2) Start hierarchical calculation and processing from the second group of data. Set: x2 is the currently collected data; x1 is the first collected data; X is the change amount;

[0034] x1 is the value after processing the hierarchical filtering. In this way, the adopted value can achieve the effect of value deviation integration, and when the data changes slowly, the integration retains the true value.

[0035] Formula: △X = |X2 - X1|; "△X" is the change amount of the background magnetic field and noise interference, and different hierarchical filtering depths are empowered according to the threshold size of the noise interference of this terminal safety monitoring system to obtain the sample true value for calculation.

[0036] 3) The established mathematical model for hierarchical weight distribution;

[0037] Let: SX be the value after hierarchical Gaussian filtering:

[0038] When X ≤ 0.01 (nT); SX = (x1 * 9 + x2) / 10

[0039] When (0.01 < X ≤ 0.015); SX = (x1 * 10 + x2) / 11

[0040] When (0.015 < X ≤ 0.02); SX = (x1 * 11 + x2) / 12;

[0041] When (0.02 < X ≤ 0.025); SX = (x1 * 12 + x2) / 13

[0042] When (0.025 < X ≤ 0.03); SX = (x1 * 13 + x2) / 14;

[0043] When (0.03 < X ≤ 0.035); SX = (x1 * 14 + x2) / 15

[0044] When (0.035 < X ≤ 0.04); SX = (x1 * 15 + x2) / 16;

[0045] When (0.04 < X ≤ 0.045); SX = (x1 * 16 + x2) / 17

[0046] When (0.045 < X ≤ 0.05); SX = (x1 * 17 + x2) / 18

[0047] When (0.05 < X ≤ 0.055); SX = (x1 * 18 + x2) / 19

[0048] After the above data hierarchical filtering calculation, perform the processing of reducing the incremental mean square error.

[0049] Let SX0 be the value after the previous layer of stratification, and △X0 be the difference between the value after the current layer of stratification and the value after the previous layer of stratification: △X0 = |SX - SX0|;

[0050] When △X0 ≤ 0.01 (nT); SX = SX0

[0051] When △X0 > 0.01, SX = SX - 0.01 when (SX - SX0) > 0;

[0052] Or SX = SX + 0.01 when (SX - SX0) < 0.

[0053] Assume that the magnetic moment of the target object is M, and the true value SX obtained above is the magnetic field value detected at a certain plane point of the intelligent terminal system. The algorithm studied uses multi-point difference differential calculation to detect the distance as R, and the distance between each sensor is r. The calculation formula is: d△(SX-SX+r)=M / R 3

[0054] SX and SX+r are the values obtained by hierarchically intelligent processing of the magnetic field values (i.e., magnetic force data) collected by two terminal system sensors with a distance of r between them.

[0055] For example, it can identify the magnetic force situation around the intelligent security terminal. While positioning and measuring the magnetic force situation near the monitoring point, it can directly monitor the objects or natural factors that cause magnetic field changes, thus assisting the monitoring personnel in making judgments and decisions.

[0056] To meet the needs of users for remote security prevention and control and detection, an intelligent security terminal, which is a high-quality integrated device for remote detection and monitoring, can not only quickly exchange information data over a long distance, but also control the intelligent terminal through the network system to operate the instrument.

[0057] In the embodiment of the present invention, a satellite real-time positioning system is adopted, which can perform multi-point monitoring in a wide area, accurately locate the coordinates of each monitoring point, and achieve the effects of switching the monitoring screen and selecting real-time data. Combined with a video acquisition module, it can directly see the cause of the magnetic anomaly when the magnetic anomaly is detected, reducing the misjudgment of the monitoring personnel due to data anomalies caused by faults or environmental factors, or the cause of the abnormal change that cannot be known due to insufficient data, facilitating the monitoring personnel to judge and handle the magnetic anomaly situation.

[0058] As Figure 2 shown, optionally, the intelligent security terminal 101 includes an acquisition module 1011, a central processing module 1013, and a communication module 1012. Among them, the acquisition module at least includes a magnetic force detection probe, a camera unit, and a GPS (Global Positioning System) / GNSS (global navigation satellite system) positioning unit. The magnetic force detection probe is used to collect magnetic force data within the preset range of the intelligent security terminal. The camera unit is used to collect video data within the preset range of the intelligent security terminal. The GPS / GNSS positioning unit is used to collect the position data of the intelligent security terminal. Among them, the GNSS positioning unit is a space-based radio navigation positioning system that can provide users with all-weather 3D coordinates, speed, and time information at any location on the earth's surface or near-earth space.

[0059] Specifically, the intelligent security terminal includes a collection module, which includes a magnetic detection probe, a camera unit, and a GPS / GNSS positioning unit. In the specific implementation process, after selecting appropriate instruments and components, the instruments and components can be tested, calibrated, and the reliability, integrity, stability, etc. of the data collected by each component can be verified. For example, the reliability and stability of each magnetic detection probe and camera can be verified.

[0060] By collecting magnetic data within the preset range of the intelligent security terminal, and through the monitoring probe, i.e., the camera, the situation near the monitoring point is transmitted to the central processing module in real time through the video cable, and then packaged and transmitted to the upper computer, and then parsed and restored into a video signal by the upper computer and displayed on the monitor. High-speed video signal transmission can be achieved through the camera to realize real-time monitoring. The situation near the monitoring point can be judged through the collected video information. If there are factors causing changes in magnetic data, it can be observed in time, and it can assist the monitoring personnel to judge whether the change in magnetic data is caused by natural factors or human factors, improving the monitoring efficiency.

[0061] A GPS / / GNSS Beidou module is also set in the intelligent security terminal to provide coordinate position information. After the GPS / GNSS module receives the satellite signal, after being parsed and processed by the central processing module, the received position information is packaged and sent to the upper computer. After being processed by the upper computer, the position coordinates of each monitoring point are displayed on the map, which is convenient for the monitoring personnel to carry out monitoring management.

[0064] As Figure 3 shown, specifically, the intelligent security terminal includes an acquisition system, parameter setting, file transfer, and data management. The intelligent security terminal receives various instructions sent by the upper computer, such as acquisition instructions, parameter adjustment instructions, and setting instructions, and then collects various security information through the acquisition module, including satellite signals, video signals, magnetic signals, and other data. Then, the security information is sent to the central processing module in the intelligent security terminal through RS232. The central processing module stores the received security information and sends it to the upper computer after packaging. The upper computer processes and saves the security information.

[0065] Data management can also be performed on the intelligent security terminal. For example, file creation, file deletion, etc. Among them, file creation can be automatic or manual.

[0066] Optionally, the magnetic detection probe is placed within a preset range of the monitoring point to detect magnetic objects within the preset range of the monitoring point, and to judge the size of the detected object according to the magnitude of the detected magnetic force change.

[0067] Optionally, the accuracy of the magnetic detection probe is at least 0.1 nT or 0.01 nT.

[0068] Specifically, when the intelligent security terminal is placed near the monitoring point, the magnetic detection probe will detect magnetic objects around, such as vehicles, iron and steel items. By the magnitude of the data change, the size, magnetic strength and distance of the detected object can be judged, and barrier-free detection of the space area can be achieved. When the central processing module receives the instruction sent by the host computer, it performs operations such as data acquisition, stop, cycle setting, storage setting, etc. according to the instruction, and at the same time returns the execution parameters to the host computer and prepares to receive the next instruction.

[0069] According to the different probes, the accuracy and resolution of the transmitted data are different. The accuracy of 0.1 nT or 0.01 nT is equipped as needed, and different models of magnetic instruments are provided according to the detection type.

[0070] Optionally, the central processing module 1013 also includes a temperature sensor.

[0071] Optionally, the central processing module is also used to receive the operation instructions of stop collection, cycle setting, and storage setting sent by the host computer and return the execution parameters corresponding to the operation instructions to the host computer.

[0072] Specifically, the central processing module is the core of the entire intelligent security terminal. It is a highly integrated processing system that integrates data acquisition, data processing, data transmission, instruction reception, device control, and intelligent early warning.
