[0002] With the rapid development of modern science and technology, the forms of security threats are becoming increasingly complex and diverse. Especially in the fields of public security and personal privacy protection, the demand for prevention of hidden and high-tech threats has increased dramatically. These threatening devices are often small in size and highly concealed, making them difficult to effectively discover through conventional methods. Therefore, nonlinear node detection technology has emerged as the times require and has become one of the important technical means to cope with the above challenges.

[0003] At present, when conducting environmental safety detection based on nonlinear node detection technology, it is difficult to provide accurate feedback on the surface condition and detection function condition of the detection equipment before detection, and it is impossible to accurately judge the degree of adverse impact of the corresponding influencing factors on the accuracy of the detection results during the detection process, which makes it difficult to improve the accuracy of environmental safety detection results, and is not conducive to the detection of explosive devices, eavesdropping and spying equipment, and the degree of intelligence is low;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0008] The surface information processing module obtains the surface image of the nonlinear node detector body, analyzes the surface condition of the nonlinear node detector body based on the surface image, and generates a surface normal signal or a surface abnormal signal. When the surface abnormal signal is generated, it is displayed through the central control panel and an early warning is issued;

[0009] When generating a normal surface signal, the semiconductor node test body and the metal corrosion node test body provided with the device are used to perform a functional test on the nonlinear node detector body. The detection verification module analyzes the functional test information to generate a normal verification signal or an abnormal verification signal, and displays the abnormal verification signal through the central control panel and issues an early warning when the abnormal verification signal is generated.

If the detector impact value exceeds the preset detector impact threshold value, the impact symbol PX-1 is assigned to the corresponding collision impact;

[0033] The number of collision impacts between the nonlinear node detector body and the collision symbol PX-1 in the historical stage is obtained and marked as the detector collision damage frequency table value, and the detector impact value of all collision impacts corresponding to the collision symbol PX-1 is averaged to obtain the detector impact inspection value;

[0034] And collect various environmental parameters of the environment in which the nonlinear node detector body is located in real time. If there are environmental parameters that do not meet the corresponding preset data requirements, it is judged that the nonlinear node detector body is in an abnormal environmental state, and the total length of time that the nonlinear node detector body is in an abnormal environmental state in the historical stage is obtained and marked as the environmental abnormal time value, and the interval length between the production date of the nonlinear node detector body and the current date is collected and marked as the detector production interval value;

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1: Figure 1-3 As shown, the present invention proposes an environment safety detection device based on a smart terminal, including a nonlinear node detector body, the nonlinear node detector body including a central control panel, a head end display structure, a battery compartment and a telescopic rod, the central control panel is located between the battery compartment and the telescopic rod, the battery compartment is an openable structure, and a battery for powering the detector is installed in the battery compartment;

[0047] The head-end display structure is connected to the central control panel through a telescopic rod, and the telescopic rod is released and fixed by a ring lock; a searchlight and a detection head are provided on the back of the head-end display structure. The searchlight is used to illuminate the detected area, and the detection head is used to detect the sending and receiving of signals.

[0048] The front of the central control panel is provided with a display area and a key area. The display area is located above the key area. The key area is provided with a detector switch key, up and down keys, left and right keys, a confirmation key, a menu key and a searchlight switch key.

[0049] The side walls of the center control panel are equipped with a speaker, headphone jack, charging indicator light and Type-C interface. The speaker is used to play the alarm sound, the headphone jack is used to output the alarm sound through the headphone, and the Type-C interface is used to charge through an external power adapter. When charging with an adapter, the charging indicator light is red, and when fully charged, the charging indicator light is green. When there is no battery in the battery compartment, the charging indicator light is alternating between red and green.

[0050] The information displayed on the display interface of the central control panel includes date (year-month-day), battery status (displaying the current remaining battery power), transmission frequency (displaying the current actual transmission frequency of the device), transmission power (displaying the current power status or actual power value of the device) and alarm mode (displaying the current alarm mode of the device); when the menu button is clicked to enter the main menu, the main menu includes three submenus: parameter settings, alarm settings and system settings;

[0051] Among them, in the parameter setting (setting the parameters of the device), there are three submenus including transmit power, transmit frequency and receive gain. The transmit power submenu includes two options: power setting and automatic adjustment; power setting: used to set the transmit power, and the power can be adjusted by the up, down or left, right buttons, in steps of 5%;

[0052] Automatic adjustment: used to turn on / off the automatic power adjustment function; among them, automatic adjustment is turned on: during detection, the appropriate transmission power is selected according to the actual distance to the object to be measured (the farther the distance, the greater the power, the closer the distance, the smaller the power) to ensure the best detection results; automatic adjustment is turned off: the transmission power is manually selected, and it remains unchanged during detection after manual adjustment; Transmission power quick setting: in the initial interface of the central control panel, the transmission power can be directly set through the "up and down buttons".

[0053] Transmitting frequency (adjusting the transmitting frequency of the device) includes two options: frequency setting and automatic selection. Manual selection: the frequency can be adjusted through the "up and down buttons" or "left and right buttons", the "up and down buttons" step by 1MHz, and the "left and right buttons" step by 5MHz; automatic selection: after turning on, the device can automatically select the transmitting frequency (only automatically select the frequency once each time it is turned on, and it is displayed on the headend startup interface and the central control interface at the same time); Transmitting frequency quick setting: in the initial interface of the central control panel, you can press the "confirm button" to directly enter the transmitting power adjustment interface.

[0054] It should be noted that in the same area, when two or more devices are working at the same time, if they are all at the same transmission frequency, frequency interference may occur between the devices. At this time, the transmission frequencies of the devices need to be staggered to avoid misjudgment caused by frequency interference.

[0055] The receiving gain is used to set the receiving sensitivity of the device, including high (representing high gain, maximum detection distance), medium (representing medium gain, moderate detection distance), and low (representing low gain, short detection distance).

[0056] In the alarm setting, there are three submenus: alarm volume, alarm threshold and vibration mode. The alarm volume is used to adjust the alarm decibel value detected by the device. The alarm volume can be adjusted by pressing the "up and down buttons" or "left and right buttons". The "up and down buttons" step by 1%, and the "left and right buttons" step by 5%. Or, in the initial interface of the central control panel, the alarm volume can be set directly by pressing the "left and right buttons". The alarm threshold is used to set the alarm threshold of the second harmonic and the third harmonic. When the set threshold is reached, an alarm is triggered. The alarm threshold can be set by pressing the "up and down buttons" or "left and right buttons". The "up and down buttons" step by 1%, and the "left and right buttons" step by 5%.

[0057] The vibration mode is used to set the strength of the device's vibration alert, including three options: strong vibration, weak vibration, and vibration off.

[0058] In the system settings, there are five submenus, including system date (set the system date, you can change the size of the numbers through the up and down keys, and adjust the year, month and day through the left and right keys), system time (set the system time, you can change the size of the numbers through the up and down keys, and adjust the hour, minute and second through the left and right keys), sleep time (adjust the automatic sleep time of the device; after setting, the device starts the sleep countdown when it is left stationary, achieving the effect of intelligent power saving), product information (display product version information) and factory reset (restore the system information of the device to the factory state, you can confirm whether to restore the factory settings through the up and down buttons on the central control, and the device will automatically restart after confirming the factory reset).

[0059] Furthermore, if Figure 4 As shown, a processor, a surface information processing module, a detection and verification module, a scanning monitoring module and a detection and alarm analysis module are provided in the central control panel, and the processor is communicatively connected to the surface information processing module, the detection and verification module, the scanning monitoring module and the detection and alarm analysis module;

[0060] Among them, the surface information processing module obtains the surface image of the nonlinear node detector body, analyzes the surface condition of the nonlinear node detector body based on the surface image, and generates a surface normal signal or a surface abnormal signal. When the surface abnormal signal is generated, it is displayed through the central control panel and an early warning is issued so that the operator can check or replace the equipment in time, thereby ensuring the accuracy of the environmental safety detection results and the stability and smoothness of the detection process; the specific operation process of the surface information processing module is as follows:

[0061] The surface image of the nonlinear node detector body is obtained and marked as the actual image, and the actual image is compared with the standard image of the nonlinear node detector body. The deformation area of ​​the nonlinear node detector body (i.e., the area where there are collapses, protrusions, etc. on the nonlinear node detector body) is obtained through the comparison. If there is no deformation area, it indicates that there is no abnormality in the surface condition of the equipment, and a surface normal signal is generated;

[0062] If there is a deformation area, the deformation volume of the corresponding deformation area is collected and marked as a deformation detection value, and the deformation detection value is numerically compared with a preset deformation detection threshold. If the deformation detection value exceeds the preset deformation detection threshold, it indicates that the deformation of the corresponding deformation area is more serious, and the corresponding deformation area is marked as a damaged area; if there is a damaged area on the nonlinear node detector body, it indicates that the surface condition of the equipment is abnormal, and a surface abnormality signal is generated;

[0063] If there is no damaged area on the nonlinear node detector body, the number of deformed areas is obtained and marked as the deformation number detection value, and the deformation detection values ​​of all deformed areas are summed up to obtain the total deformation measurement value, and the deformation detection value with the largest value is marked as the deformation detection amplitude value;

[0064] The deformation number detection value BL, the total deformation measurement value BS and the deformation detection amplitude value BD are numerically calculated by the formula BX=a1*BL+(a2*BS+a3*BD) / 2 to obtain the detector surface analysis value BX, wherein a1, a2 and a3 are preset proportional coefficients, and a1>a3>a2>0; and the larger the value of the detector surface analysis value BX, the more serious the surface deformation condition of the equipment is in general;

[0065] The detector surface analysis value BX is numerically compared with the preset detector surface analysis threshold. If the detector surface analysis value BX exceeds the preset detector surface analysis threshold, it indicates that the surface deformation condition of the equipment is generally serious, and a surface abnormality signal is generated; if the detector surface analysis value BX does not exceed the preset detector surface analysis threshold, it indicates that the surface deformation condition of the equipment is generally light, and a surface normal signal is generated.

[0066] When generating a normal surface signal, the nonlinear node detector body is functionally tested using the randomly equipped (i.e., built-in) semiconductor node test body and the metal rust node test body. The detection verification module determines whether the detection of each test body has obvious false alarms or obvious distance attenuation based on the functional detection information. If there are no obvious false alarms and obvious distance attenuation, a normal verification signal is generated; if there are obvious false alarms or obvious distance attenuation, an abnormal verification signal is generated. When the abnormal verification signal is generated, it is displayed on the central control panel and an early warning is issued so that the operator can promptly repair or replace the equipment, thereby further ensuring the accuracy of the environmental safety detection results and the stable and smooth progress of the detection process.

[0067] In addition, when generating a normal verification signal, the nonlinear node detector body performs environmental safety detection on the target area, and the scanning monitoring module performs real-time monitoring and analysis on the detection process, generates a high-impact detection signal or a low-impact detection signal through analysis, and displays and issues an early warning on the central control panel when a high-impact detection signal is generated, so that the operator can make detection adjustments, such as slowing down the scanning speed, maintaining scanning stability, etc., which is conducive to making the environmental safety detection results more accurate; the specific operation process of the scanning monitoring module is as follows:

[0068] During the detection process, the ambient temperature and ambient humidity of the target area are collected, the ambient temperature is calculated by difference with the median of the preset suitable detection temperature range and the absolute value is taken to obtain the detection temperature value, and the ambient humidity is calculated by difference with the median of the preset suitable detection humidity range and the absolute value is taken to obtain the detection humidity value; wherein, the larger the values ​​of the detection temperature value and the detection humidity value are, the more unfavorable it is for the stable detection of the nonlinear node detector body, and it is easy to cause a large deviation in the detection result;

[0069] By formula The detected temperature value TG and the detected humidity value TM are numerically calculated to obtain the detected environment value TX, wherein hp1 and hp2 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the detected environment value TX is, the worse the environmental condition of the target area is, which is more unfavorable for the stable detection of the nonlinear node detector body;

[0070] Compare the detection environment value TX with the preset detection environment threshold. If the detection environment value TX exceeds the preset detection environment threshold, it indicates that the environmental condition of the target area is poor, which is not conducive to the stable detection of the nonlinear node detector body, and a detection high impact signal is generated;

[0071] If the detection environment value TX does not exceed the preset detection environment threshold, a number of detection time points are set within a unit time, and the scanning speed (i.e., the data value of the moving speed of the nonlinear node detector body) and the jitter amplitude (i.e., the data value of the shaking degree of the nonlinear node detector body) of the nonlinear node detector body at the corresponding detection time points are collected;

[0072] and comparing the scanning speed and jitter amplitude at the corresponding detection time point with the preset scanning speed threshold and the preset jitter amplitude threshold, respectively. If the scanning speed or the jitter amplitude exceeds the corresponding preset threshold, indicating that the scanning control performance of the operator on the nonlinear node detector body at the corresponding detection time point is poor, the corresponding detection time point is marked as an abnormal time point;

[0073] The number of abnormal time points is obtained and the ratio thereof is calculated with the total number of detection time points to obtain an abnormal time detection value, and the scanning speeds of all detection time points are averaged to obtain a detection speed detection value, and the jitter amplitudes of all detection time points are averaged to obtain a detection jitter detection value;

[0074] By formula The scanning detection influence value QW is obtained by numerically calculating the asynchronous detection value QN, the detection speed detection value QL and the detection jitter detection value QK; wherein uk1, uk2 and uk3 are preset proportional coefficients, uk1>uk3>uk2>0; and the larger the value of the scanning detection influence value QW, the worse the operator's control performance on the nonlinear node detector body is, and the greater the adverse effect on the accuracy of the detection result;

[0075] The scanning detection influence value QW is numerically compared with the preset scanning detection influence threshold. If the scanning detection influence value QW exceeds the preset scanning detection influence threshold, it indicates that the operator's control performance of the nonlinear node detector body is generally poor, and the adverse effect on the accuracy of the detection result is large, then a high detection influence signal is generated; if the scanning detection influence value QW does not exceed the preset scanning detection influence threshold, it indicates that the operator's control performance of the nonlinear node detector body is generally good, and the adverse effect on the accuracy of the detection result is small, then a low detection influence signal is generated.

[0076] During the detection process, the detection alarm analysis module obtains the second harmonic signal strength and the third harmonic signal strength, and judges whether there are suspicious electronic devices and non-electronic devices in the target area based on this, and displays the judgment results through the central control panel. When it is judged that there are suspicious electronic devices or non-electronic devices, the central control panel will issue an early warning, which can help users quickly judge the nature of the target. It is mainly used to assist users in making judgments, and has a high accuracy rate.

[0077] It should be noted that when suspicious electronic equipment (semiconductor nodes) is detected in the target area, the second harmonic signal strength is significantly stronger than the third harmonic signal strength; when non-electronic equipment such as metal oxides is detected (metal corrosion nodes), the third harmonic signal strength is significantly stronger than the second harmonic signal strength; by actively transmitting the fundamental wave signal to the object to be measured, the second harmonic and third harmonic signals are generated after passing through the object to be measured, and the purpose of identifying whether there are suspicious electronic products is achieved based on the detection of the reflected harmonic signal. Semiconductor nodes and metal corrosion nodes can be detected and identified, and the detection of explosive devices, eavesdropping and peeping equipment can be realized. It is suitable for tasks such as search and disposal of explosives, anti-eavesdropping, and anti-peeping.

[0078] Embodiment 2: Figure 5As shown, the difference between this embodiment and the first embodiment is that the processor is communicatively connected to the detector damage detection module. When generating a surface abnormality signal or a verification abnormality signal, the detector damage detection module performs a loss analysis on the nonlinear node detector body, generates a high loss signal or a low loss signal through analysis, and displays and issues an early warning through the central control panel when a high loss signal is generated. The operator replaces the equipment in time and scraps the corresponding nonlinear node detector body as needed, which is conducive to making corresponding treatment measures reasonably, avoiding unnecessary waste of manpower, material resources and time, and has a high degree of intelligence. The specific analysis process of the detector damage detection module is as follows:

[0079] When the nonlinear node detector body is subjected to a collision impact, the maximum value, average value and duration of the impact force of the collision impact on the nonlinear node detector body are collected and marked as force amplitude, force detection value and force time value respectively;

[0080] The force amplitude LF, the force detection value LP and the force time value LS are numerically calculated by the formula LK=(c1*LF+c2*LP) / 2+c3*LS to obtain the detector impact value LK, wherein c1, c2 and c3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the detector impact value LK is, the greater the damage caused by the corresponding collision impact to the nonlinear node detector body is; the detector impact value LK is numerically compared with the preset detector impact threshold value, if the detector impact value LK exceeds the preset detector impact threshold value, it indicates that the corresponding collision impact causes greater damage to the nonlinear node detector body, and the corresponding collision impact is assigned a collision symbol PX-1;

[0081] The number of collision impacts between the nonlinear node detector body and the collision symbol PX-1 in the historical stage is obtained and marked as the detector collision damage frequency table value, and the detector impact value of all collision impacts corresponding to the collision symbol PX-1 is averaged to obtain the detector impact inspection value;

[0082] And collect various environmental parameters (such as temperature, dust concentration, etc.) of the environment (including the use environment and the storage environment) where the nonlinear node detector body is located in real time. If there are environmental parameters that do not meet the corresponding preset data requirements, it is judged that the nonlinear node detector body is in an abnormal environmental state, and the total length of time that the nonlinear node detector body is in an abnormal environmental state in the historical stage is obtained and marked as the environmental abnormal time value, and the interval length between the production date of the nonlinear node detector body and the current date is collected and marked as the detector production interval value;

[0083] By formula The detector damage frequency table value SK, the detector impact inspection value SL, the environmental time difference value SF and the detector production interval value SN are numerically calculated to obtain the detector damage inspection value SY; wherein ny1, ny2, ny3 and ny4 are preset proportional coefficients, ny1>ny2>ny3>ny4>0; and the larger the value of the detector damage inspection value SY, the worse the equipment condition of the nonlinear node detector body;

[0084] The detector damage detection value SY is numerically compared with the preset detector damage detection threshold. If the detector damage detection value SY exceeds the preset detector damage detection threshold, it indicates that the equipment condition of the nonlinear node detector body is poor, and a high loss signal is generated; if the detector damage detection value SY does not exceed the preset detector damage detection threshold, it indicates that the equipment condition of the nonlinear node detector body is good, and a low loss signal is generated.

[0085] The working principle of the present invention is as follows: when in use, a surface image of the nonlinear node detector body is obtained before detection through a surface information processing module, and the surface condition of the nonlinear node detector body is analyzed based on the surface image. When a surface normal signal is generated, a semiconductor node test body and a metal corrosion node test body are used to perform a functional test on the nonlinear node detector body. The detection verification module determines whether the detection of each test body has an obvious false alarm or obvious distance attenuation based on the functional detection information, and issues an early warning when a surface normal signal or a verification abnormal signal is generated, so that the operator can repair or replace the equipment in time, which is conducive to ensuring the accuracy of the environmental safety detection results and the safety of the detection process. It proceeds stably and smoothly. When generating a normal verification signal, the nonlinear node detector body is used to detect the environmental safety of the target area. The scanning monitoring module monitors and analyzes the detection process in real time to determine the degree of adverse effects of the corresponding influencing factors on the accuracy of the detection results, which is convenient for operators to make timely detection adjustments to make the environmental safety detection results more accurate. During the detection process, the detection alarm analysis module is used to determine whether there are suspicious electronic equipment and non-electronic equipment in the target area. It can detect and identify semiconductor nodes and metal rust nodes, and realize the detection of explosive devices, eavesdropping and peeping equipment. It is suitable for tasks such as search and disposal of explosives, anti-eavesdropping, and anti-peeping.
