Description

Technical Field

[0001] The invention relates to the field of inclinometers, and in particular to an inclinometer and a synchronous timing measurement method thereof. Background Art

[0002] In the safety monitoring industry of engineering construction, the method for automated monitoring of internal displacement of foundation pits and slopes mainly uses fixed inclinometers for measurement. At the same time, due to the requirements for internal displacement measurement, it is necessary to match the depth of the inclinometer for data calculation. Therefore, it is necessary to measure at a fixed depth and equal intervals.

[0003] In the prior art, traditional fixed inclinometers are installed at equal intervals, with installation intervals varying from 0.5m, 1m, 1.5m, and 2m. According to an inclinometer hole with a depth of 30m, one inclinometer hole needs to be installed with 15 to 20 fixed-rod inclinometers, which has high cost and large installation and maintenance workload. The existing automatic lifting inclinometer communicates wirelessly, but at the actual engineering site, water inside the pipeline or the pipeline depth of more than 30 meters will cause particularly serious interference to the wireless communication signal, resulting in failure of normal communication and low reliability. Summary of the invention

[0004] Based on this, an object of the present invention is to provide an inclinometer and a synchronous timing measurement method thereof, which can effectively solve the above-mentioned deficiencies in the prior art.

[0005] An inclinometer comprises a cabinet, a winding assembly arranged in the cabinet, and a box arranged on the top of the winding assembly, wherein the winding assembly comprises a winding disk structure arranged on the cabinet, a driving structure for driving the winding disk structure, and a cable structure wound on the winding disk structure, an inclinometer structure is connected to one end of the cable structure away from the winding disk structure, the inclinometer structure comprises a shell and a first MCU arranged in the shell, a first Bluetooth communication module electrically connected to the first MCU for communication, a MEMS sensor module for measuring data, a battery module for power supply, and an RTC clock module for time synchronization are also arranged in the shell, and a second Bluetooth communication module communicatively connected to the first Bluetooth communication module, a power supply module for power supply, and a second MCU electrically connected to the power supply module and communicatively connected to the second Bluetooth communication module for controlling the driving structure are arranged in the box.

[0006] Furthermore, a control module is provided in the box body and is connected to the second MCU for controlling the driving structure.

[0009] Furthermore, a roller structure is provided at the bottom of the cabinet to facilitate the movement of the cabinet.

[0010] Furthermore, a pulley structure is provided on the outside of the inclinometer structure to facilitate the movement of the inclinometer structure.

[0011] On the other hand, the present invention also provides a synchronous timing measurement method of an inclinometer, the measurement method comprising:

[0012] S1, measuring the pipeline depth;

[0013] Among them, the specific steps for measuring the pipeline depth are:

[0014] Measure the pipeline depth and calculate the number of data sets required for collection based on the measured pipeline depth and corresponding distance interval.

[0015] S2, measurement data transmission;

[0016] The specific steps of measuring the transmission data are as follows:

The first MCU performs calculations according to the received startup time, the collection interval time, and the number of groups of data to be collected, and obtains N time points for collecting data according to the startup time.

[0021] S4, start collecting data;

[0022] The specific steps for collecting data are as follows:

[0023] The first step is to control the driving structure through the second MCU to drive the winding drum structure to rotate, so that the cable structure lowers the inclinometer structure to the top of the pipeline, and when the RTC clock module reaches the set start time, the inclinometer structure starts to measure the data of the top of the pipeline;

[0024] In the second step, after the RTC clock module reaches the collection interval time, the second MCU controls the driving structure to drive the winding disk structure to rotate, so that the cable structure drives the inclinometer structure to move downward by a distance interval, and when the RTC clock module reaches the time point of collecting data, the inclinometer structure starts to measure the data of the current position;

[0025] The third step is to repeat the collection step of the second step until the inclinometer structure reaches the bottom of the pipeline, and when the RTC clock module reaches the time point for collecting data, the inclinometer structure starts to measure the data of the bottom of the pipeline;

[0026] Step 4: After the RTC clock module reaches the collection interval time, the second MCU controls the driving structure to drive the winding disk structure to rotate, so that the cable structure drives the inclinometer structure to move upward by a distance interval, and when the RTC clock module reaches the time point of collecting data, the inclinometer structure starts to measure the data of the current position;

[0027] Step 5, repeating the collection steps of step 4 until the inclinometer structure reaches the top of the pipeline and collects N sets of data;

[0029] Furthermore, the pipeline depth is B, the distance interval is M, the number of groups is equal to the number of time points N for collecting data, and 2B / M+1=N.

[0030] Furthermore, the specific steps of measuring pipeline data with the inclinometer structure are:

[0031] The inclinometer structure collects 50 groups of data at a frequency of 5 Hz and sorts them according to size. The front and rear 10 groups of data are removed and the middle 30 groups of data are taken to determine the data availability. If there is abnormal out-of-range data, the out-of-range data is marked, the out-of-range data is removed, the average value of the remaining data is calculated, and all the data is stored; when the data meets the requirements and is within the normal range, the average value of the data is directly calculated and the data is stored.

[0032] Furthermore, the specific steps for collecting data transmission are:

[0033] After the inclinometer structure collects N groups of data, when the inclinometer structure reaches the top of the pipeline, the inclinometer structure transmits the N groups of measurement data stored in the first MCU to the second MCU through the first Bluetooth communication module through the second Bluetooth communication module.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a first Bluetooth communication module connected to the first MCU for communication, and by setting a second Bluetooth communication module connected to the second MCU for communication, the first MCU and the second MCU can perform data transmission through the first Bluetooth module and the second Bluetooth communication module; by setting an RTC clock module, the inclinometer structure can be started at a fixed time as needed; by placing the inclinometer structure in the required measurement pipeline, and by setting a MEMS sensor module, a battery module and a first MCU, the inclinometer structure can independently complete the measurement and store the inclinometer data in the pipeline, and can work normally without being disturbed in an area with water or too deep inside; after the data collection of the current position is completed, a start instruction can be issued to the driving structure through the second MCU, and the cable structure can be driven by the winding disk structure to realize the lifting and lowering of the inclinometer structure, and the entire inclinometer work can be automatically completed through the cooperation of the RTC clock module, so that there is no need to install multiple fixed-pole inclinometers, saving costs and reducing workload.

[0060] S1, measuring the pipeline depth;

[0061] Among them, the specific steps for measuring the pipeline depth are:

[0062] Measure the pipeline depth and calculate the number of data sets required for collection based on the measured pipeline depth and corresponding distance interval.

[0063] Furthermore, the pipeline depth is B, the distance interval is M, the number of groups is equal to the number of time points N for collecting data, and 2B / M+1=N.

[0064] It should be noted that, in this embodiment, the pipeline depth is 3m, the distance interval is 0.5m, and the number of groups is 13.

[0065] S2, measurement data transmission;

[0066] The specific steps of measuring the transmission data are as follows:

[0068] S3, wireless time synchronization;

[0069] The specific steps of wireless time synchronization are as follows:

[0070] The second MCU 33 sends the current time, the start time, and the collection interval time to the first MCU 42 in the inclinometer structure 40 through the second Bluetooth communication module 31. The first MCU 42 performs calculations according to the received start time, the collection interval time, and the number of groups of data to be collected, and obtains N time points for collecting data according to the start time.

[0071] It should be noted that, in this embodiment, there are 13 time points for collecting data.

[0072] S4, start collecting data;

[0073] The specific steps for collecting data are as follows:

[0074] In the first step, the second MCU 33 sends a command to the control module 34, and the control module 34 controls the driving structure 22 to drive the winding disc structure 21 to rotate, so that the cable structure 23 lowers the inclinometer structure 40 to the top of the pipeline. When the RTC clock module 46 reaches the set start time, the inclinometer structure 40 starts to measure the data on the top of the pipeline;

[0075] In the second step, after the RTC clock module 46 reaches the collection interval time, the second MCU 33 automatically sends a command to the control module 34, and the control module 34 controls the driving structure 22 to drive the winding disk structure 21 to rotate, so that the cable structure 23 drives the inclinometer structure 40 to move downward by 0.5m.

[0079] Furthermore, the specific steps of the inclinometer structure 40 measuring pipeline data are as follows:

[0080] The inclinometer structure 40 collects 50 groups of data at a frequency of 5 Hz and sorts them according to size. The front and rear 10 groups of data are removed and the middle 30 groups of data are taken to determine the data availability. If there is abnormal out-of-range data, the out-of-range data is marked, the out-of-range data is removed, the average value of the remaining data is calculated, and all the data is stored; when the data meets the requirements and is within the normal range, the average value of the data is directly calculated and the data is stored.

[0084] It can be understood that the method collects data through time synchronization, automatic lifting and lowering, timed collection, and equal-interval grouping. The inclinometer structure 40 collects data, synchronizes time, and transmits data when it is at the top of the pipeline (close to the second MCU33), and the control module 34 is controlled by the second MCU33 when the inclinometer 40 is lowered or raised in the pipeline.
