[0034] The operation control center generates a scene positioning analysis signal and sends the scene positioning analysis signal to the scene positioning analysis unit. After receiving the scene positioning analysis signal, the scene positioning analysis unit analyzes the real-time use positioning of the millimeter-wave radar, and infers whether the current setting point of the millimeter-wave radar is reasonable through the position analysis of the use area, so that the anti-interference performance of the millimeter-wave radar can meet the actual operation requirements, thereby improving the control efficiency of the millimeter-wave radar and the detection efficiency of the millimeter-wave radar.

[0037] Obtain the actual waveform change area of ​​the corresponding detection wave after the obstacle at the currently set distribution point is blocked when transmitting the radar detection wave, and mark the actual waveform change area of ​​the corresponding detection wave after the obstacle at the currently set distribution point is blocked when transmitting the radar detection wave as BGM;

[0038] The above collected information is uniformly marked as radar positioning information, and substituted into the formula to obtain the scene positioning analysis coefficient of the millimeter wave radar, where the formula is: Where D is the scene positioning analysis coefficient, vgf1, vgf2 and vgf3 are preset proportional coefficients, e is a natural constant, and β is an error correction factor with a value of 0.978;

[0039] Compare the scene positioning analysis coefficient of the millimeter wave radar with the positioning analysis coefficient threshold:

[0040] If the scene positioning analysis coefficient of the millimeter wave radar exceeds the positioning analysis coefficient threshold, it is inferred that the real-time set distribution points in the current detection area are unreasonable, and a point movement signal is generated and sent to the operation control platform. After receiving the point movement signal, the operation control platform moves the currently set distribution points and ensures that the coverage of the current detection area meets the requirements;

[0042] At the same time, the operation control platform generates an interference impact analysis signal and sends the interference impact analysis signal to the interference impact analysis unit. After receiving the interference impact analysis signal, the interference impact analysis unit analyzes the interference impact of the millimeter-wave radar in the detection area, infers whether there is interference to the millimeter-wave radar in the current detection area, and whether there is detection impact under the interference. Through real-time interference impact analysis, the current operating environment is detected, and the anti-interference performance of the millimeter-wave radar is tested to ensure the detection efficiency of the detection area;

[0043] According to the specifications of the millimeter-wave radar at the real-time distribution point, the detection frequency of the millimeter-wave radar and the signal wave penetration distance at the corresponding detection frequency are collected and marked as frequency parameters and distance parameters respectively;

[0044] The numerical floating span of the actual detection frequency when detecting with the set frequency parameters during the real-time detection of the millimeter-wave radar is obtained, and the maximum deviation value between the real-time distance parameter and the preset distance parameter when detecting with the set frequency parameters is obtained. The numerical floating span of the actual detection frequency when detecting with the set frequency parameters during the real-time detection of the millimeter-wave radar and the maximum deviation value between the real-time distance parameter and the preset distance parameter when detecting with the set frequency parameters are marked as interference information and impact information, respectively, and compared with the frequency numerical floating span threshold and the parameter maximum deviation threshold, respectively:

[0045] If the numerical floating span of the actual detection frequency when detecting with the set frequency parameters during the real-time detection of the millimeter-wave radar exceeds the frequency numerical floating span threshold, or the maximum deviation value between the real-time distance parameter and the preset distance parameter when detecting with the set frequency parameters exceeds the parameter maximum deviation threshold, it is inferred that the interference impact analysis of the current millimeter-wave radar detection process is abnormal, and a detection inefficiency signal is generated and sent to the operation control platform. After receiving the detection inefficiency signal, the operation control platform adjusts the detection cycle of the current millimeter-wave radar and performs detection in a suitable environment, and performs detection adjustment according to the specific value of the actual detection frequency to ensure the detection efficiency of the current area;

[0047] The operation control platform generates an operation fault detection signal and sends the operation fault detection signal to the operation fault detection unit. After receiving the operation fault detection signal, the operation fault detection unit performs operation fault detection on the millimeter-wave radar.

Through data collection and analysis, it is inferred whether there is a fault risk in the current millimeter-wave radar, so as to facilitate timely maintenance and control of the millimeter-wave radar, and ensure that the detection efficiency of the detection area can meet the actual detection needs, thereby improving the operational feasibility of the millimeter-wave radar, and also ensuring the risk avoidance performance of the millimeter-wave radar, timely fault prediction and control, and ensuring the accuracy of detection data collection;

[0048] During the millimeter wave radar detection process, as the detection distance increases, the continuous rising span of the minimum value of the radar operating temperature when the current detection frequency is executed is obtained, and the continuous rising span of the minimum value of the radar operating temperature when the current detection frequency is executed is marked as WS;

[0049] When the duration of the weather changes in the detection area increases during the millimeter-wave radar detection process, the amount of missing detection data at the current detection time after any internal radar fails under the current millimeter-wave radar redundant design is obtained, and the amount of missing detection data at the current detection time after any internal radar fails under the current millimeter-wave radar redundant design is marked as QS; wherein the corresponding detection data is represented by the position and distance of the corresponding object at each moment, and missing means that the mobile detection object lacks the corresponding position information at a certain moment;

[0050] Obtain the speed at which the lower limit of the signal wave penetration distance setting corresponding to the millimeter wave radar detection frequency under different weather environments is reduced, and mark the speed at which the lower limit of the signal wave penetration distance setting corresponding to the millimeter wave radar detection frequency under different weather environments is reduced as JD;

[0051] The above collected data are uniformly marked as fault detection information, and substituted into the formula to obtain the operation fault detection coefficient of the millimeter wave radar, where the formula is: Wherein, C is the operating fault detection coefficient, f1, f2 and f3 are preset proportional coefficients respectively;

[0052] Compare the operating fault detection coefficient of the millimeter wave radar with the fault detection coefficient threshold:

[0053] If the operation fault detection coefficient of the millimeter-wave radar exceeds the fault detection coefficient threshold, it is inferred that the current millimeter-wave radar operation fault detection is abnormal, and a detection and maintenance signal is generated and sent to the operation control platform. After the operation control platform receives the detection and maintenance signal, it performs equipment maintenance on the millimeter-wave radars at the current distribution points;

[0055] Embodiment 2

[0056] See also Figure 2As shown, the system is connected to an operation trend analysis unit in communication. After completing the operation fault detection, an operation trend analysis signal is generated and sent to the operation trend analysis unit. After receiving the operation trend analysis signal, the operation trend analysis unit analyzes the operation trend of the millimeter-wave radar and infers whether there is an abnormal risk in the current millimeter-wave radar operation, so as to provide a timely warning when the risk does not occur, so as to ensure the execution efficiency of the millimeter-wave radar detection operation and ensure full-time monitoring of the detection area.

[0057] The amount of decrease in the rising span of the actual detection distance when the radar transmission power increases under different detection environments during the operation of the millimeter-wave radar is collected, and the amount of decrease in the rising span of the actual detection distance when the radar transmission power increases under different detection environments during the operation of the millimeter-wave radar is marked as frequency addition information;

[0058] Obtain the frequency of missing data at any position in the same detection area when the radar transmit power is constant under the same detection environment during the operation of the millimeter-wave radar, and mark the frequency of missing data at any position in the same detection area when the radar transmit power is constant under the same detection environment during the operation of the millimeter-wave radar as constant frequency information;

[0059] And the frequency increase information and the constant frequency information are compared with the span reduction threshold and the missing frequency threshold respectively:

[0060] If the frequency-added information exceeds the span reduction threshold, or the constant frequency information exceeds the missing frequency threshold, it is inferred that the real-time detection operation trend of the millimeter-wave radar is abnormal, and an efficiency reduction signal is generated and sent to the operation control platform. After receiving the efficiency reduction signal, the operation control platform maintains the millimeter-wave radar and tests and regulates the equipment performance;

[0061] If the frequency-added information does not exceed the span reduction threshold, and the constant frequency information does not exceed the missing frequency threshold, it is inferred that the real-time detection operation trend of the millimeter-wave radar is normal, and a normal efficiency signal is generated and sent to the operation control platform.

[0062] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;
