Description

Technical Field

[0001] The invention relates to the technical field of slope displacement monitoring, in particular to a method for automatically identifying the physical sequence of inclinometer probes. Background Art

[0002] An inclinometer is a device for measuring deep displacement. It is mainly used for monitoring deep displacement at locations such as highway slopes, river embankment slopes, and reservoir slopes, and for assessing and warning of collapse risks.

[0003] Traditional inclinometers are composed of several probes connected by cables. Manually recording the sequence of probe numbers is labor-intensive and may cause errors. Once a recording error occurs, the device cannot be verified to be correct when placed at a deep displacement, affecting the accuracy of data analysis. For spliced ​​inclinometers, probes can be flexibly loaded and unloaded, and recording the sequence of probe numbers is more prone to errors. How to accurately identify the physical sequence of inclinometer probes without the need for manual recording operations and reduce the possibility of errors from the source is a problem we need to solve. To this end, a method for automatically identifying the physical sequence of inclinometer probes is provided. Summary of the invention

[0031] The sensor temperature of the probe is set with a standard value range. The probes are numbered sequentially from top to bottom, and the inclination angle and displacement of each probe are recorded;

[0032] The inclination angle, displacement and probe number are combined to generate a sequence pair. If the sensor temperature of a probe with a certain number exceeds the standard value range, it is marked as an abnormal temperature and the sequence pair is used as geological data.

[0033] Furthermore, the process of generating probe data includes:

[0034] The inclinometer is composed of a bus and a plurality of serial ports, and the serial ports include a first serial port, a second serial port and a third serial port;

BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Figure 1 It is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0060] like Figure 1 As shown, a method for automatically identifying the physical order of inclinometer probes includes the following steps:

[0061] Step S1: creating a slope displacement measurement platform and setting a data exchange terminal for receiving data from each probe of the inclinometer;

[0062] Step S2: Processing the working data generated during the operation of the inclinometer to generate probe data and geological data;

[0063] Step S3: uploading the probe data and geological data to the slope displacement measurement platform through the data exchange terminal;

[0064] Step S4: Perform fault analysis on the data in the slope displacement measurement platform and generate a probe physical sequence.

[0065] Create a slope displacement measurement platform, and set up an information verification unit in the slope displacement measurement platform. Construction personnel input construction information through the information verification unit and conduct review;

[0066] Construction personnel are divided into technical personnel and general personnel. Construction information includes employee information and operation information. The employee information of technical personnel includes employee number, employee contact information and employee category; the employee information of general personnel includes employee number and employee contact information; the operation information includes operation time, operation location and operation content;

[0067] After the review is passed, a temporary data interaction space associated with the construction personnel is established in the slope displacement measurement platform. The employee number in the employee information is used as the login account, and the employee contact information is used as the login password. The construction personnel enter the temporary data interaction space based on the login account and login password.

[0068] The operations performed by ordinary personnel are as follows: first survey and select a suitable slope, drill holes in the slope, install the inclinometer tube between the unstable soil layer and the stable soil layer to achieve the purpose of fixing the inclinometer tube on one side, and after the placement is completed, perform soil burial operations, fill with sand, gravel and soil until the entire inclinometer tube is completely covered, and then stop filling, record the operation time and location at this time, and combine the two operation contents to generate a buried tube record form;

[0069] Technical personnel can be divided into operation and maintenance personnel and troubleshooting personnel according to employee categories. The operation content of the operation and maintenance personnel is to read the probe data and geological data in the slope displacement measurement platform, and conduct quantitative analysis on them, record the operation time and operation location, and generate an operation and maintenance record form after merging the operation content; the operation content of the troubleshooting personnel is to obtain the operation and maintenance record form, and generate a corresponding troubleshooting table based on the operation and maintenance record form to record the corresponding fault problems;

[0070] A data exchange terminal is set in the slope displacement measurement platform, and a plurality of link ports are set in the data exchange terminal. The collector of the inclinometer uploads the probe data and geological data to the slope displacement measurement platform through the link port;

[0071] It should be further explained that, in the specific implementation process, the operation and maintenance record form can record all the data information of all the probes arranged on the inclinometer tube. The troubleshooting personnel can generate a troubleshooting table based on the operation and maintenance record form, so that the fault problems encountered during the operation of the inclinometer tube can be solved in time; the inclinometer tube is fixed on one side so that the inclinometer tube can be displaced under the movement of the underground mud and soil, and the probe records the corresponding displacement information.

[0072] Start the inclinometer on the DTU management platform on the ground, record the working data generated by the inclinometer, and process the working data into probe data and geological data;

[0073] Specifically, the process of processing working data into geological data includes:

[0074] The inclinometer is provided with several probes for collecting working data, including sensor temperature, inclination angle, and displacement;

[0075] The sensor temperature of each probe is set with a standard value range, denoted as LR. The probes are numbered from top to bottom, denoted as i, i∈1, 2, 3...n, n is a natural number, and the inclination angle of each probe is recorded as p, and the displacement is recorded as q. The inclination angle p, the displacement q and the probe number i are combined to generate a sequence pair, denoted as R, R=<p,q,i> ;

[0076] If the sensor temperature of the probe numbered i exceeds LR, it is marked as abnormal temperature, and the sequence pair R is used as geological data;

[0077] The inclinometer uses other redundant serial ports of the MCU controller, which are composed of a bus and several serial ports. The other serial ports include a first serial port, a second serial port and a third serial port. Each probe is provided with the first serial port, the second serial port and the third serial port. The first serial port of each probe is directly connected to the bus, and the second serial port and the third serial port are connected to adjacent probes.

[0078] Set up a collector, which is directly linked to the DTU management platform. A collection box is set in the collector. The first probe is connected to the collection box. The physical sequence of the probes is broadcasted through the collection box. The physical sequence of the probes is used as probe data, and the acquired probe data is uploaded to the collector.

[0079] Specifically, the process of the acquisition box broadcasting and acquiring the physical order of the probes includes:

[0080] The acquisition box broadcasts a command of reporting number, recorded as St, marks the third serial port as the upper serial port, and marks the second serial port as the lower serial port;

[0081] Get the instruction St. When the probe with the probe number i receives the instruction St, it sends a response through the uplink serial port, which is recorded as Reply. The response Reply includes the probe number and the probe counter. The value recorded by the probe counter is recorded as j, and the initial value of j is 1.

[0082] After receiving the reply Reply, the adjacent probe with probe number i+1 adds 1 to the probe counter value j and forwards the reply Reply to the upstream serial port of the same probe;

[0083] Repeat the above operation until all probes receive the reply and perform the +1 operation. When the acquisition box receives the reply from a probe, the value of the probe counter of the probe is set to its physical sequence number.

[0084] The response time of each probe and the time when the acquisition box sends the broadcast are recorded as t, and the sum of the response time and the broadcast time of all probes is obtained to obtain the total response time, which is recorded as T, T = (n + 1) * t;

[0085] It should be further explained that the traditional inclinometer probe only uses one serial port and acquisition box to send and receive data through the bus. Since all probes are hung on the bus, the purpose of automatic identification cannot be achieved. The use of the redundant serial port of the MCU and the DTU management platform for RS485 / Modbus bus architecture can avoid bus conflicts and support data concurrency for each probe. The original total response time of using one serial port and acquisition box was n*2t. After using the bus architecture, the total response time becomes (n+1)*t, and the response speed is greatly improved.

[0086] The probe data obtained in the acquisition box is uploaded to the collector, and the probe data and geological data are summarized and uploaded to the slope displacement measurement platform through the data exchange terminal;

[0087] Specifically, the process of uploading the probe data and geological data to the slope displacement measurement platform in an encrypted manner includes:

[0088] Acquire probe data and geological data, convert the two into hexadecimal digital sequences, and perform key encryption on the hexadecimal digital sequences;

[0089] Randomly select two prime numbers in the hexadecimal digital sequence, record them as S1 and S2, calculate the product of the two, record them as N, N = S1 * S2, obtain ψ (N), ψ (N) = (S1-1) * (S2-1);

[0090] A large integer is generated by intercepting the hexadecimal digit sequence, denoted as e, which satisfies gcd(e, ψ(N)) = 1, and the integer e is used as the encryption key;

[0091] Let the decryption key be d, then d = [k × ψ (N) + 1] / e, where k ≥ 1 and is an integer;

[0092] The hexadecimal digital sequence is encrypted by an encryption key to generate a ciphertext, and the ciphertext is uploaded to the slope displacement measurement platform. The slope displacement measurement platform obtains the corresponding decryption key to decrypt the ciphertext and restore the probe data and geological data;

[0093] It should be further explained that the encryption key can be obtained by any user, but the decryption key is set with corresponding permissions and can only be obtained by people with authorized permissions for decryption. By encrypting the data recorded by the inclinometer, the privacy of the data is guaranteed and a good security effect is achieved.

[0094] Obtain the decrypted probe data and geological data. The operation and maintenance personnel and troubleshooting personnel located in the slope displacement measurement platform perform fault analysis on the geological data and solve the existing faults. The probe data is analyzed to generate a probe physical sequence.

[0095] Specifically, the process of fault analysis of geological data includes:

[0096] Get the sensor temperature in the geological data. If it is an abnormal temperature, stop the inclinometer connected to the DTU management platform and record it as a first-level fault information;

[0097] If the sensor temperature is within the normal range, the sequence pair R in the geological data is analyzed, the sequence pair R is obtained, and the displacement q, the inclination angle p and the probe number i in R are detected;

[0098] The probe number i is positively correlated with the displacement depth. Each probe has an equal and fixed length L. A standard displacement depth data table is provided to record the standard displacement amount λ and inclination angle θ corresponding to each displacement depth.

[0099] If the displacement q in R is not within the range of λ, it is recorded as secondary fault information;

[0100] If the inclination angle p in R is not within the range of θ, it is recorded as level 3 fault information;

[0101] The operation and maintenance personnel summarize the first-level fault information, the second-level fault information, and the third-level fault information to generate an operation and maintenance record form;

[0102] The troubleshooter obtains the operation and maintenance record form. If a level 1 fault message is received, the inclinometer tube is rearranged. If a level 2 or level 3 fault message is received, it indicates that there is a risk at the operation site and soil sampling and geological analysis are required at the operation site.

[0103] Obtain probe data and set a two-dimensional array, obtain probe counters of all probes, and store the physical sequence numbers corresponding to the probe counters in the second dimension of the two-dimensional array;

[0104] The probe number is stored in the first dimension of the two-dimensional array, and the two-dimensional array is exported to form a physical order sequence of the probes.

[0105] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
