Description

Technical Field

[0001] This invention relates to the field of ranging technology, and in particular to a device and control method for remotely calibrating and measuring the angle of a monitoring device. Background Technology

[0002] Currently, in the construction industry, automated monitoring equipment is widely used for deformation monitoring of buildings and structures under construction and already completed. However, during long-term monitoring, these devices frequently experience angular errors, rendering them ineffective and typically requiring manual on-site calibration. Due to various reasons, personnel often cannot arrive on-site immediately and must wait for the next maintenance window to perform calibration. Summary of the Invention

[0003] The purpose of this invention is to provide a device and control method for remotely calibrating and measuring the angle of a monitoring device. This device can detect abnormal angles of the monitoring device remotely, automatically locate the monitoring target by remotely controlling the monitoring device, obtain the correct angle of the monitoring device under the current state, and then remotely calibrate the angle of the monitoring device to achieve normal operation of the monitoring device.

[0004] This invention is achieved through the following technical solution: a device for remotely calibrating and measuring the angle of a monitoring device, comprising...

[0013] A control method for a remote calibration and angle measurement device for monitoring equipment, characterized by comprising the following steps:

[0014] Step 1: Connect the monitoring equipment remotely via the network controller using a Y-cable to obtain the original positioning angle status of the monitoring equipment and confirm whether the measurement angle of the monitoring equipment is abnormal. If there is no abnormality, use the meteorological sensor to obtain real-time data of temperature, humidity and air pressure at the location of the monitoring equipment and push it to the monitoring equipment via the Y-cable to achieve normal working status of the monitoring equipment; if there is an abnormality, perform calibration.

[0015] Step 2, Calibration and Setting: Remotely set the starting horizontal angle, starting zenith angle, horizontal search range, vertical search unit, and search grid interval of the monitoring device through the network controller, confirm the preferred scanning direction, and perform remote automatic search for the target prism until the target is found.

[0016] Step 3: Based on the coordinates (X1, Y1) of the target point obtained through remote search and the coordinates (X2, Y2) of the monitoring device, use the formula L= Then, perform coordinate inverse calculation to calculate the distance L between the target point and the monitoring equipment;

[0017] Step 4: The distance L calculated remotely based on the coordinates is automatically matched with the distance information of all monitoring targets and monitoring devices in the system to find the measuring point P that best matches the distance L.

[0018] Step 5: Remotely calculate the azimuth angle α of the measured point in the relative coordinate system based on the matched measured point P;

[0019] Step 6: Remotely push the calculated azimuth angle α in the current relative coordinate system to the monitoring device to remotely set and calibrate the measurement angle of the monitoring device;

[0027] The present invention will now be described in detail with reference to the accompanying drawings:

[0028] A device for remotely calibrating and measuring angles of monitoring equipment, comprising:

[0029] The enclosure is waterproof.

[0030] The power supply is installed inside the enclosure;

[0031] The voltage regulator is installed inside the enclosure and connected to the power supply.

[0032] The network controller, installed inside the enclosure, is used for remote network communication;

[0033] A relay, installed inside the enclosure, is used for remote physical power disconnection;

[0034] The weather sensor, installed outside the enclosure, is used to acquire the current local temperature, humidity, and weather data;

[0035] The Y-shaped cable is installed outside the enclosure and connected to the network controller for data communication with the monitoring equipment.

[0036] The network controller, relays, and meteorological sensors are all electrically connected to the power supply via voltage regulators; the monitoring equipment is a total station with an integrated servo motor.

[0037] The enclosure here can be waterproof. The power supply provides power to the entire device, and the voltage regulator stabilizes the power supply. A network controller (4GDTU) connects to the monitoring equipment via a Y-cable to remotely acquire the equipment's status. If an abnormal measurement angle is detected, the monitoring equipment is physically powered off remotely via a relay. Then, the power supply system remotely provides secondary power to the monitoring equipment. A three-in-one meteorological sensor (temperature, humidity, and air pressure) acquires real-time data on temperature, humidity, and air pressure at the monitoring equipment's location and transmits this data to the monitoring equipment via the Y-cable to ensure normal operation.

[0038] In the above implementation process, the status of the monitoring equipment is acquired first, and real-time data on temperature, humidity, and air pressure are then pushed after confirmation. Since temperature, humidity, and air pressure data can affect measurement accuracy, after the equipment is running, the environmental data is first acquired through the sensors and set up to ensure accuracy in the later stages.

[0039] like Figure 2 As shown: A control method for a remote calibration and angle measurement device for monitoring equipment includes the following steps:

[0040] Step 1: Connect the monitoring equipment remotely via the network controller using a Y-cable to obtain the original positioning angle status of the monitoring equipment and confirm whether the measurement angle of the monitoring equipment is abnormal. If there is no abnormality, use the meteorological sensor to obtain real-time data of temperature, humidity and air pressure at the location of the monitoring equipment and push it to the monitoring equipment via the Y-cable to achieve normal working status of the monitoring equipment; if there is an abnormality, perform calibration.

[0041] The standard for determining whether the measurement angle of the monitoring equipment is abnormal is as follows: Based on the coordinates of the monitoring equipment and the coordinates of the measuring point, calculate the azimuth angle from the instrument to the measuring point. The horizontal circle angle range of the monitoring equipment is 0~360°. When the 0-degree circle direction of the monitoring equipment is consistent with the X-axis direction of the measurement coordinate system, it indicates that the measurement angle of the monitoring equipment is normal; if the 0-degree circle direction of the monitoring equipment is inconsistent with the X-axis direction of the measurement coordinate system, the angle of the monitoring equipment is abnormal (e.g., ...). Figure 3 (As shown).

[0042] Step 2, Calibration and Setting: Remotely set the starting horizontal angle, starting zenith angle, horizontal search range, vertical search unit, and search grid interval of the monitoring device through the network controller, confirm the preferred scanning direction, and perform remote automatic search for the target prism until the target is found.

[0043] Step 3: Based on the coordinates (X1, Y1) of the target point obtained through remote search and the coordinates (X2, Y2) of the monitoring device, use the formula L= Then, perform coordinate inverse calculation to calculate the distance L between the target point and the monitoring equipment;

[0044] Step 4: The distance L calculated remotely based on the coordinates is automatically matched with the distance information of all monitoring targets and monitoring devices in the system to find the measuring point P that best matches the distance L.

[0045] Step 5: Remotely calculate the azimuth angle α of the measured point P in the relative coordinate system based on the matched measured point P; here, the formula α=arctan(Y2-Y1) / (X2-X1) is mainly used to calculate the azimuth angle α of the measured point P in the relative coordinate system (e.g., Figure 4 (As shown).

[0046] Step 6: Remotely push the calculated azimuth angle α in the current relative coordinate system to the monitoring device to remotely set and calibrate the measurement angle of the monitoring device;

[0047] Step 7: The remote control monitoring equipment performs calibration measurements, compares the current measurement value with the historical measurement value to verify that there are no errors, and the monitoring equipment resumes normal operation.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
