[0023] In a second aspect, the present application also discloses a method for measuring inclination of a fixed fully automatic inclinometer, comprising the steps of: S0: Connect the inclinometer host and the inclinometer probe through a driving line, and place the inclinometer probe in the inclinometer tube; The host is installed above the inclinometer tube, and the parameters are set and debugged, and step S1 is executed; S1: According to the sampling interval and sampling time set in advance, when the sampling time is reached, the processing unit and the inclinometer probe of the inclinometer host are started; Turn on the motor and open the motor self-locking function; The inclinometer host and inclinometer probe both start collecting depth data; The inclinometer probe moves downward in the inclinometer tube under the action of gravity. If it reaches the bottom of the inclinometer tube (the value of the tension sensor suddenly decreases and reaches the preset inclinometer tube depth), the motor is controlled to pause and step S2 is executed; If the inclinometer probe gets stuck during the lowering process (the value of the tension sensor suddenly decreases but the depth value collected by the inclinometer host is less than the preset inclinometer tube depth), the inclinometer host controls the motor to lift the inclinometer probe and then lower it again; If the inclinometer probe reaches the bottom of the inclinometer casing within three attempts or less, step S2 is executed; If the bottom of the inclinometer tube cannot be reached after three attempts, the lowering will stop, the host will upload the abnormal information to the platform, and the inclinometer operation will be terminated; S2: When the depth data collected in the inclinometer probe stops changing, wait for 5 seconds, collect the inclination data and cache it, and then execute step S3; S3: After the inclinometer host waits for 10 seconds, the control motor lifts the inclinometer probe 500 mm and then stops; If the inclinometer probe has not reached the top of the inclinometer tube and the limit switch has not been triggered, step S3 is executed; If the inclinometer probe reaches the top of the inclinometer tube and triggers the limit switch, execute step S4; If the inclinometer probe is stuck (the value of the tension sensor suddenly increases), the control motor is paused, the inclinometer probe moves downward under the action of gravity, and the motor is turned on to lift the inclinometer probe again; If the angle probe passes this height in three attempts or less, continue with this step; If the lifting still fails after three attempts, the lifting will stop, the motor will be turned off, and the inclinometer host will report the abnormal information to the platform, enter sleep mode, and will not start the collection until the sampling is restarted after the manual processing is completed on site; If the inclinometer probe does not move for a long time (the depth data does not change within 1 minute), sampling stops and the system enters sleep mode.

[0024] S4: Turn off the motor, the motor is self-locked, and the control unit in the inclinometer probe uploads all the cached measuring point data (depth and inclination) to the inclinometer host through the Bluetooth module. The inclinometer host caches the received data and uploads it to the platform through 4G at the same time; S5: The control unit in the inclinometer probe collects the battery power information of the probe and uploads it to the inclinometer host through the Bluetooth module: if the battery power is higher than the preset threshold, no charging is required, and the host and the probe enter sleep mode; if the battery power is lower than the preset threshold, the inclinometer battery in the inclinometer probe is charged through the wireless charging transmitter board, and the probe power is obtained every 10 minutes. If the battery is full, charging is stopped, and the inclinometer host and the inclinometer probe enter sleep mode; if the sampling time is reached during charging, charging is stopped (the wireless charging transmitter board is powered off), and step S1 is executed.

[0025] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The inclinometer host controls the automatic movement of the inclinometer probe in the inclinometer tube to achieve automatic data collection, reduce the need for manual operation, and improve the efficiency and safety of operation.

[0065] like Fig.13 As shown, when a fixed fully automatic inclinometer disclosed in this embodiment is working, the wire rope terminal of the inclinometer probe 2 is marked with an A+ symbol to indicate the direction of measurement (A+ direction), and the direction of the plane where the upper and lower pulleys 116 of the inclinometer probe 2 are located is consistent with the A direction. In the actual working process, we define the direction to be measured (i.e., the direction with deformation tendency such as collapse and landslide) as the A+ direction, and the direction perpendicular to the A direction as the B direction. There are two inclination sensors 222 in the inclinometer probe 2. The A-axis sensor measures the inclination in the plane of the pulley 116, and the B-axis sensor measures the inclination of the plane perpendicular to the pulley 116. The inclinometer disclosed in this application does not need to perform multiple measurements in different directions in order to reduce equipment errors, but can realize automatic measurement of different directions in one measurement.

[0066] like Figure 2 , 7 The figure shows a further implementation of this embodiment, wherein the inclinometer probe 2 is further provided with a guide wheel 25; A guide groove is provided on the inner wall of the inclinometer tube 3; The guide wheel 25 cooperates with the guide groove, so that the inclinometer probe 2 can move up and down under the guiding and limiting action of the guide groove.

[0067] like Figure 7 The figure shows a further implementation of this embodiment, wherein one or more guide wheels 25 are provided on the inclinometer probe 2 along the axial direction; The guide wheel 25 includes a torsion shaft 251, a connecting rod 252 and two wheel bodies 253; The two wheel bodies 253 are respectively arranged on both sides of the connecting rod 252; The middle part of the connecting rod 252 is connected to the torsion shaft 251. In the initial state, the connecting rod 252 forms an inclination angle of 5-15 degrees with the axial direction of the inclinometer probe 2. When the inclination angle changes, the torsion shaft 251 generates a restoring torque.

[0068] like Figure 2 The figure shows a further implementation of this embodiment, wherein the communication unit 24 is a probe Bluetooth connection system, which is used to transmit the information processed and cached by the control unit 21 to the inclinometer host 1 when the inclinometer probe 2 completes the inclinometer task and rises to the top of the inclinometer tube 3.

[0069] like Figure 7 The figure shows a further implementation of this embodiment, in which a buffer pad 26 is provided at the bottom of the inclinometer probe 2 to avoid a hard collision when the inclinometer probe 2 reaches the bottom of the inclinometer tube 3 .

[0070] like Figure 7 , 9 10 shows a further implementation of this embodiment, further comprising a nozzle seat 4; The pipe mouth seat 4 is arranged on the top 3 of the inclinometer pipe; The nozzle seat 4 includes an integrated clamping joint 41, a connecting plate 42 and an extension pipe 43; The size of the clamping joint 41 in the horizontal direction is larger than the inner diameter of the inclinometer tube 3, and is used for overlapping with the inclinometer tube 3; The connecting plate 42 is arranged on the clamping joint 41 and is provided with a connecting hole for being fastened and connected with the inclinometer tube 3; The extension tube 43 is disposed at the lower end of the clamping joint 41 and extends into the inclinometer tube 3; A channel with the same diameter and coaxial with the extension tube 43 is provided in the clamping joint 41 . The diameter of the channel is greater than or equal to the diameter of the upper end of the inclinometer probe 2 , so that the inclinometer probe 2 can enter the pipe mouth seat 4 .

[0071] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The fixed fully automatic inclinometer measures the inclination angle change of the inclinometer casing 3 at different depths in real time through the high-precision inclination sensor 222, and calculates the horizontal displacement increment, thereby realizing efficient and accurate monitoring of geological structure deformation and improving the accuracy and reliability of monitoring data.

[0072] (2) The inclinometer probe 2 is automatically raised and lowered in the inclinometer tube 3, and data collection can be completed without human intervention. The automated operation process greatly improves work efficiency, reduces labor costs, and avoids errors caused by human operation.

[0073] (3) The two tilt sensors 222 provided on the inclinometer probe 2 can simultaneously monitor two mutually perpendicular directions (directions A and B) on the same horizontal plane, thus realizing automatic measurement in multiple directions without the need for repeated measurements, further improving the monitoring efficiency and comprehensiveness.

[0074] (4) The sensing unit 13 detects key parameters of the equipment during operation in real time. For example, when the tension is abnormal, the equipment stops working in time to prevent damage to the equipment. At the same time, the monitoring data is transmitted to the processing unit 15 in real time through the communication unit 14, which facilitates real-time monitoring and early warning, and timely detection and handling of potential safety hazards.

[0075] (5) The power supply unit 12 includes a solar panel 121, a host battery 122 and a wireless charging transmitting panel 123, which converts solar energy into electrical energy and has a wireless charging function, thereby reducing dependence on traditional energy, reducing energy consumption and operating costs, and complying with environmental protection concepts.

[0076] (6) The inclinometer host 1 integrates a lifting unit 11, a power supply unit 12, a sensor unit 13, a communication unit 14 and a processing unit 15. The units are electrically connected. The highly integrated design makes the device compact and easy to operate, thereby improving the overall performance and reliability of the equipment.

[0077] (7) Through the coordination of the guide wheel 25 and the guide groove, as well as the design of the buffer pad 26 at the bottom of the inclinometer probe 2, the inclinometer probe 2 is effectively prevented from being deflected or collided during the lifting process, thereby improving the safety performance and stability of the equipment.

[0078] (8) The communication unit 14 includes a 4G connection system 141, a WIFI connection system 142 and a host Bluetooth connection system 143, supports multiple communication modes, can adapt to data interaction requirements in different environments, and ensure the real-time and reliability of data transmission.

[0079] Example 2 In a second aspect, the present application further discloses a method for measuring inclinometer using a fixed fully automatic inclinometer in Embodiment 1, comprising the steps of: S0: Connect the inclinometer host and the inclinometer probe through a driving line, and place the inclinometer probe in the inclinometer tube; The host is installed above the inclinometer tube, and the parameters are set and debugged, and step S1 is executed; S1: According to the sampling interval and sampling time set in advance, when the sampling time is reached, the processing unit and the inclinometer probe of the inclinometer host are started; Turn on the motor and open the motor self-locking function; The inclinometer host and inclinometer probe both start collecting depth data; The inclinometer probe moves downward in the inclinometer tube under the action of gravity. If it reaches the bottom of the inclinometer tube (the value of the tension sensor suddenly decreases and reaches the preset inclinometer tube depth), the motor is controlled to pause and step S2 is executed; If the inclinometer probe gets stuck during the lowering process (the value of the tension sensor suddenly decreases but the depth value collected by the inclinometer host is less than the preset inclinometer tube depth), the inclinometer host controls the motor to lift the inclinometer probe and then lower it again; If the inclinometer probe reaches the bottom of the inclinometer casing within three attempts or less, step S2 is executed; If the bottom of the inclinometer tube cannot be reached after three attempts, the lowering will stop, the host will upload the abnormal information to the platform, and the inclinometer operation will be terminated; S2: When the depth data collected in the inclinometer probe stops changing, wait for 5 seconds, collect the inclination data and cache it, and then execute step S3; S3: After the inclinometer host waits for 10 seconds, the control motor lifts the inclinometer probe 500 mm and then stops; If the inclinometer probe has not reached the top of the inclinometer tube and the limit switch has not been triggered, step S3 is executed; If the inclinometer probe reaches the top of the inclinometer tube and triggers the limit switch, execute step S4; If the inclinometer probe is stuck (the value of the tension sensor suddenly increases), the control motor is paused, the inclinometer probe moves downward under the action of gravity, and the motor is turned on to lift the inclinometer probe again; If the angle probe passes this height in three attempts or less, continue with this step; If the lifting still fails after three attempts, the lifting will stop, the motor will be turned off, and the inclinometer host will report the abnormal information to the platform, enter sleep mode, and will not start the collection until the sampling is restarted after the manual processing is completed on site; If the inclinometer probe does not move for a long time (the depth data does not change within 1 minute), sampling stops and the system enters sleep mode.

[0080] S4: Turn off the motor, the motor is self-locked, and the control unit in the inclinometer probe uploads all the cached measuring point data (depth and inclination) to the inclinometer host through the Bluetooth module. The inclinometer host caches the received data and uploads it to the platform through 4G at the same time; S5: The control unit in the inclinometer probe collects the battery power information of the probe and uploads it to the inclinometer host through the Bluetooth module: if the battery power is higher than the preset threshold, no charging is required, and the host and the probe enter sleep mode; if the battery power is lower than the preset threshold, the inclinometer battery in the inclinometer probe is charged through the wireless charging transmitter board, and the probe power is obtained every 10 minutes. If the battery is full, charging is stopped, and the inclinometer host and the inclinometer probe enter sleep mode; if the sampling time is reached during charging, charging is stopped (the wireless charging transmitter board is powered off), and step S1 is executed.

[0081] It is worth noting that this embodiment is an inclinometer method for a fixed fully automatic inclinometer disclosed in Embodiment 1, and the technical features recorded in this embodiment can also serve as an explanation and supplement to the technical features in the device in Embodiment 1.

[0082] By adopting the above technical solution, the present invention has the following beneficial effects: (1) By presetting the sampling interval and time, the inclinometer process is automatically controlled, which reduces manual intervention and improves work efficiency and data continuity.

[0083] (2) During the lowering or lifting process of the inclinometer probe, it can intelligently identify and handle abnormal situations such as getting stuck or being unable to reach the bottom or top. Through multiple attempts and automatic adjustments, the stability and reliability of the system are enhanced.

[0084] (3) Ensure that the inclination data is collected after the inclinometer probe is stable and stationary, avoiding errors during movement and improving the accuracy and precision of the data.

[0085] (4) Through Bluetooth and 4G modules, the measurement point data can be uploaded to the platform in real time, which facilitates remote monitoring and analysis and improves the timeliness and convenience of data processing.

[0086] (5) Automatically monitor the battery level of the inclinometer probe and intelligently select charging or sleep mode based on the battery level, effectively extending the use time and life of the equipment while reducing unnecessary energy consumption.

[0087] (6) In abnormal situations (such as multiple failed attempts, long periods of no movement, etc.), it can automatically stop sampling and report abnormal information to protect the equipment from further damage, while reminding the user to intervene in time.

[0088] (7) The technical solution includes a variety of processing strategies for different situations, such as multiple attempts and automatic adjustment, so that the system can flexibly adapt to various complex environments and working conditions.
