[0002] With the increase in urban population, the problem of urban land resources is becoming increasingly serious. As a transportation hub in the urban circle, rail transit occupies a large area. In order to coordinate the problem of tight urban land resources and low land utilization rate around the depot, the rail transit-oriented depot superstructure construction model came into being. The ground depot superstructure construction project organically integrates urban rail transit with urban land planning, improves the commercial value of land around the transportation section, and drives the rapid growth of the urban economy, but the resulting safety risks are also becoming increasingly prominent. The superstructure construction is located on the upper part of the operating depot, which will inevitably affect the internal force of the existing operating depot structure, and even affect the structural safety and durability of the depot, threatening the safety of personnel and the normal operation of subway trains.

[0003] In order to clarify the degree of disturbance caused by the construction of the ground cover to the subway depot, protect the depot structure and the safety of vehicles entering and exiting, it is necessary to monitor the deformation of the depot cover, so as to warn of the risks in the construction and take remedial construction measures. Existing building cover deflection monitoring equipment includes laser rangefinders, intelligent sensors, and GPS deformation displacement monitoring equipment. In the prior art, the relevant deflection monitoring equipment is not only unable to perform real-time monitoring of the deflection of existing building covers, but also in the prior art, when performing deflection monitoring, the monitoring results are often affected by the monitoring environment, resulting in inaccurate monitoring results.

[0048] One or more technical solutions proposed in this application have at least the following technical effects:

[0049] 1) The technical solution of the present application determines a target monitoring position on the building cover plate according to actual survey results of the area where the building cover plate is located, sets a deflection monitor at the target monitoring position, adjusts the monitoring parameters of the monitoring mechanism through a control mechanism so that the monitoring mechanism faces the position to be monitored and is in a target monitoring state, controls the monitoring mechanism to monitor the position to be monitored in a target monitoring state according to the collected current environmental monitoring data of the area where the existing building cover plate is located, and obtains monitoring data, processes the monitoring data, and obtains the deflection monitoring result of the existing building cover plate, so that the present invention can perform monitoring operations on the position to be monitored at the target monitoring position according to the collected current environmental monitoring data when in use, and finally obtains the deflection monitoring result of the existing building cover plate after data processing the monitoring operation results, thereby enabling the present invention to not only realize the function of real-time monitoring operations on the existing building cover plate, but also ensure that the deflection monitoring results will not be affected by the monitoring environment during the monitoring operation of the existing building cover plate, thereby ensuring the accuracy of the monitoring results.

[0112] S300, adjusting the monitoring parameters of the monitoring mechanism through the control mechanism so that the monitoring mechanism faces the position to be monitored and is in a target monitoring state; wherein the monitoring parameters include a monitoring direction parameter, a monitoring angle parameter, and a monitoring duration of the monitoring mechanism;

[0113] In this embodiment, the exemplary position to be monitored is a position to be monitored where a determined range finder performs continuous monitoring operations.

[0114] S400, according to the collected current environmental monitoring data of the area where the existing building cover is located, controlling the monitoring mechanism to perform monitoring operations on the location to be monitored in a target monitoring state to obtain monitoring data; wherein the current environmental monitoring data includes dust concentration data of the current environment;

[0115] In this embodiment, the dust concentration data exemplified is the dust concentration data in the air environment where the cover plate of the existing building is located.

[0116] S500: Process the monitoring data to obtain a deflection monitoring result of the existing building cover.

[0117] In this embodiment, a target monitoring position is determined on the building cover plate according to actual survey results of the area where the building cover plate is located, a deflection monitor is set at the target monitoring position, and the monitoring parameters of the monitoring mechanism are adjusted by the control mechanism so that the monitoring mechanism faces the position to be monitored and is in the target monitoring state. According to the current environmental monitoring data of the area where the existing building cover plate is located, the monitoring mechanism is controlled to perform monitoring operations on the position to be monitored in the target monitoring state to obtain monitoring data, and the monitoring data is processed to obtain the deflection monitoring results of the existing building cover plate. When used, the present invention can perform monitoring operations on the position to be monitored at the target monitoring position according to the collected current environmental monitoring data, and after data processing the monitoring operation results, the deflection monitoring results of the existing building cover plate are finally obtained, thereby enabling the present invention to not only realize the function of real-time monitoring operations on the existing building cover plate, but also ensure that the deflection monitoring results will not be affected by the monitoring environment during the monitoring operation of the existing building cover plate, thereby ensuring the accuracy of the monitoring results.

[0118] In one embodiment, step S400 includes:

[0119] S410, when the dust concentration data is less than a preset concentration, controlling the monitoring mechanism to perform monitoring operation on the position to be monitored in the target monitoring state, so as to obtain the current distance between the monitoring mechanism and the position to be monitored, and obtain the monitoring data;

[0120] It should be clearly stated that, in this embodiment, the preset concentration of the example should meet the following requirements: the preset concentration is determined by the measurement performance of the laser ranging device of the monitoring organization. Different laser ranging devices have different measurement performances, so the dust concentration has different effects on the measurement accuracy. When the detected dust concentration exceeds the measurement concentration limit of the laser ranging device, causing excessive error, the operation is stopped.

[0121] In this embodiment, a PVC connecting pipe is connected to the upper surface of the environmental monitoring device, and the detection hole on the upper surface of the PVC connecting pipe is connected to the outer surface of the monitoring box. When the monitoring device is monitoring, the external air can be transmitted from the detection hole to the environmental monitoring device through the PVC connecting pipe. The environmental monitoring device includes a dust detection unit, a humidity detection unit, and a correction unit. The dust detection unit, the humidity detection unit, and the correction unit are all connected to the controller. When the dust concentration in the external environment is too high, it will cause great interference to the laser ranging signal, causing serious measurement errors. Therefore, the dust detection unit is provided with a dust concentration threshold. When the dust concentration in the air is greater than the concentration threshold, the dust detection unit transmits a signal to the controller, and then the controller controls the angle adjustment component to restore the initial state, and turn off the rangefinder to stop monitoring. At the same time, the humidity in the environment will affect the dust detection data. When the relative humidity is high, the reading of the dust detection unit will be larger as the humidity increases, causing the dust reading to exceed the dust concentration threshold too early, causing the rangefinder to stop measuring, and thus unable to obtain monitoring data. Therefore, the humidity detection unit is provided with a humidity threshold t, and a piecewise function is established through the correction unit for correction. According to the influence of humidity on the dust detection results, the humidity correction function is divided into four sections: (0%~60%)t, (60%~75%)t, (75%~85%)t, and (85%~95%)t. In order to obtain the correction function ε (relative humidity) of each section, the average value ε' of each humidity value ε detected in advance is taken. As the initial value, the Gauss-Newton iteration method is used to obtain the values ​​of each humidity value, and then the nonlinear least squares method is used to fit the correction factor of each humidity segment to obtain a set of empirical humidity correction functions ε(RH) with relative humidity as the variable. RH is the relative humidity, which is substituted into the dust concentration calculation formula The corrected dust concentration can be obtained to avoid the phenomenon of stopping monitoring due to excessive dust concentration readings.

[0122] In this embodiment, the exemplary humidity correction function acquisition process is as follows: first, the dust concentration of the array under different humidities is pre-detected by the dust concentration detection unit and the humidity detection unit, and compared with the dust concentration in the low humidity environment, the dust concentration correction function value ε of the array under different humidities is obtained, and the average value ε' of the pre-detected humidity values ​​ε is used as the initial value, and the Gauss-Newton iteration method is used to obtain a more accurate correction function ε value for each humidity value, and then the humidity correction function is divided into four sections: (0%~60%)t, (60%~75%)t, (75%~85%)t, and (85%~95%)t, where (0%~60%)t represents 0%~60% of the humidity threshold, that is, 0%~60% relative humidity, and finally the nonlinear least squares method is used to fit the correction factors of each humidity section to obtain a set of empirical humidity correction functions ε(RH) with relative humidity as the variable, where RH is the relative humidity.

[0123] Among them: The formula of Gauss-Newton iteration method is as follows:

[0124] (1) Selection of initial value: average value ε' of each humidity value ε.

[0125] (2) Taylor series expansion. Assume that the nonlinear regression model is:

[0126]

[0127] Among them: ε is the estimated regression coefficient, the error term ε i ~N(0,σ 2 ).

[0128] set up is the regression coefficient to be estimated ε=(ε0,ε1,...,ε p-1 ) T The initial value of formula (1) f(x i ,ε) make Taylor expansion near the ε' point and ignore the second-order and above partial derivatives of the nonlinear regression model, and we get

[0129]

[0130] Substituting equation (2) into equation (1), we get

[0136] but:

[0138] Expressed in matrix form, the above formula is:

[0139] ε (0) ≈D (0) b (0) +ε,(3),

[0140] in,

[0141]

[0142] (3) Estimate the correction factor. Use the least square method to estimate the correction factor b in equation (3): (0) ,

[0143] but:

[0144] b (0) =(D(0)T D (0) ) -1 D (0)T Y (0) ,(4)

[0145] Let ε′(0) be the first alternative value, then ε ′(1) =ε ′(0) +b (0) .

[0146] Nonlinear least squares fitting is to estimate the parameters of nonlinear static model based on the minimum sum of square errors, and then find the corresponding function.

[0147] Specifically, the radiator is provided with a temperature threshold, which is determined according to the temperature resistance of the internal material of the monitoring box. When the internal temperature of the monitoring box is too high, it can be cooled down in time to protect the safe operation of the internal part of the monitoring box. The chassis is located on the inner surface of the monitoring box and is attached with a polymer polyvinyl chloride coil, which can effectively prevent water and moisture and avoid short circuit of the internal circuit of the monitoring box.

[0148] After the controller is programmed, it controls the angle adjustment component to rotate horizontally and vertically, driving the rangefinder to measure. The vertical rotation angle of the laser ranging device is set to 90° by default. The rotation transposition horizontal rotation angle is 0° as the initial state. Then the angle adjustment component drives the rangefinder to rotate vertically to measure the horizontal rotation angle 0° direction. After the horizontal rotation angle 0° direction is measured, the controller controls the angle adjustment component to drive the rangefinder to restore the initial state. Then the angle adjustment component rotates horizontally at a fixed angle, and re-measures in the above manner to obtain data of each point on the cover plate.

[0149] S420. When the dust concentration data is greater than or equal to the preset concentration, dust removal is performed on the current environment. When the dust concentration data is less than the preset concentration, the monitoring mechanism is controlled to monitor the position to be monitored in the target monitoring state to obtain the current distance between the monitoring mechanism and the position to be monitored and obtain the monitoring data.

[0150] In one embodiment, before step S500, the method further includes:

[0151] S600, uploading the monitoring data to a cloud platform;

[0152] Step S500 includes:

[0153] S510, using the cloud platform set formula 1 to perform coordinate transformation on the monitoring data to obtain the horizontal distance and vertical distance between the monitoring mechanism and the position to be monitored; wherein the formula 1 is:

[0156] S520, controlling the monitoring mechanism to continuously monitor the position to be monitored, and returning to execute the step of performing coordinate transformation on the monitoring data using the cloud platform set formula 1 to obtain the horizontal distance and the vertical distance between the monitoring mechanism and the position to be monitored, until a plurality of the horizontal distances and the plurality of the vertical distances between the monitoring mechanism and the position to be monitored are obtained;

[0157] S530, integrating all the horizontal distances and all the vertical distances to form a distance line graph between the monitoring mechanism and the position to be monitored;

[0158] S540, obtaining the current deformation amount of the position to be monitored according to the distance line graph;

[0159] S550, sequentially setting a plurality of positions to be monitored on the cover plate of the existing building and sequentially monitoring each of the positions to be monitored until the current deformation of all the positions to be monitored is obtained, thereby obtaining a deflection monitoring result of the cover plate of the existing building.

[0160] In one embodiment, step S540 includes:

[0161] S541. Calculate and obtain the current deformation of the position to be monitored using Formula 2 according to the distance line graph; wherein Formula 2 is:

[0162] W=Y K -Y K-1 ,

[0166] S552, storing all the current deformation amounts corresponding to all the positions to be monitored in the cloud platform;

[0167] S553. In the cloud platform, each current deformation is compared with a preset threshold in turn to obtain a deflection monitoring result of the existing building cover, wherein the preset threshold is A% of the design deflection deformation value, wherein A% is 60%.

[0168] It is necessary to specifically and clearly explain that the preset threshold value in this embodiment is a warning value set to ensure that the deflection deformation of the existing building cover has sufficient safety reserve, and an early warning can be issued in advance when the cover deformation develops significantly beyond this value. A high-safety warning threshold value should be set for the deflection deformation of the existing building cover to ensure that a timely warning can be issued before the cover deformation gradually develops and increases to exceed the specified deflection deformation, so as to avoid safety risks in advance.

[0169] In one embodiment, after step S553, the method further includes:
