[0002] Currently, in the construction industry, automated monitoring equipment is widely used to monitor the deformation of buildings and structures, both under construction and completed. During long-term monitoring, these devices often experience angular errors, preventing them from performing their intended functions. This often necessitates on-site calibration. For various reasons, personnel are often unable to arrive immediately on-site, requiring them to wait for the next available window to perform calibration. Summary of the Invention

[0003] The purpose of the present invention is to provide a device for remotely calibrating and measuring the angle of a monitoring device and a control method thereof, which can remotely detect abnormal angles of the monitoring device and automatically search for monitoring targets by remotely controlling the monitoring device, thereby obtaining the correct angle of the monitoring device in the current state, and then remotely calibrating the angle of the detection device to achieve the purpose of normal operation of the monitoring device.

[0004] The present invention is realized by the following technical solution: a device for remotely calibrating and measuring angles of monitoring equipment, comprising:

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 device and push it to the monitoring device via the Y-shaped cable to achieve normal working state of the monitoring device; if there is any abnormality, perform calibration;

[0015] Step 2: Calibration settings: remotely set the monitoring device's starting horizontal angle, starting zenith angle, horizontal search range, vertical search unit, and search grid interval through the network controller, confirm the priority scanning direction, and conduct remote automatic search for the target prism until the target is found;

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

[0027] The present invention is described in detail below with reference to the accompanying drawings:

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

[0029] The box body is a waterproof box body;

[0030] Power supply, installed in the box;

[0031] The voltage stabilizer is installed in the box and connected to the power supply;

[0032] The network controller is installed in the box and is used for remote network communication;

[0033] Relay, installed in the box, used for remote physical power off;

[0034] Meteorological sensor, installed outside the box, is used to obtain current local temperature, humidity, and meteorological data;

[0035] Y-shaped line, set outside the box, connected to the network controller, used for data communication connection with the monitoring equipment;

[0036] Among them, the network controller, relay, and meteorological sensor are all electrically connected to the power supply through a voltage stabilizer; and the monitoring equipment is a total station with an integrated servo motor.

[0037] The enclosure can be a waterproof box. The power supply is used to power the entire device, and the voltage stabilizer is used to stabilize the entire power supply. Through the network controller (4GDTU), a Y-shaped cable is used to connect the monitoring device to remotely obtain the monitoring device's status. If the monitoring device's measurement angle is abnormal, the monitoring device is physically powered off remotely via a relay. The power supply system then remotely repowers the monitoring device. A three-in-one temperature, humidity, and air pressure weather sensor is used to obtain real-time temperature, humidity, and air pressure data at the monitoring device's location. This real-time temperature, humidity, and air pressure data is pushed to the monitoring device via the Y-shaped cable to ensure normal operation of the monitoring device.

[0038] In the above implementation process, the monitoring device status is obtained first, and after confirmation, the real-time data of temperature, humidity, and air pressure are pushed. Because temperature, humidity, and air pressure data can affect measurement accuracy, after the device is running, the actual environmental data is obtained and set through the sensor to ensure later accuracy.

[0039] like Figure 2 As shown: A control method for remotely calibrating a measuring angle device for a monitoring device comprises the following steps:

[0040] Step 1: Use a Y-shaped cable to connect the monitoring device through the network controller to remotely obtain the original positioning angle status of the monitoring device and confirm whether the measurement angle of the monitoring device 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 device and push it to the monitoring device via the Y-shaped cable to achieve normal working state of the monitoring device; if there is any abnormality, perform calibration;

[0041] Among them, the standard for whether the measurement angle of the monitoring equipment is abnormal is to calculate the azimuth of the instrument to the measuring point based on the monitoring equipment coordinates and the measuring point coordinates. The horizontal disk angle range of the monitoring equipment is: 0~360°. When the 0-degree disk direction of the monitoring equipment is consistent with the X-axis direction of the measuring coordinate system, it means that the measurement angle of the monitoring equipment is normal; if the 0-degree disk direction of the monitoring equipment is inconsistent with the X-axis direction of the measuring coordinate system, the angle of the monitoring equipment is abnormal (such as Figure 3 shown).

[0042] Step 2: Calibration settings: remotely set the monitoring device's starting horizontal angle, starting zenith angle, horizontal search range, vertical search unit, and search grid interval through the network controller, confirm the priority scanning direction, and conduct remote automatic search for the target prism until the target is found;

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

[0044] Step 4: The distance L calculated by remote coordinate inversion is automatically matched with the distance information of all monitoring targets and monitoring equipment in the system to find a measuring point P that best matches the distance L.

[0045] Step 5: Remotely calculate the azimuth angle α of the measuring point in the relative coordinate system based on the matched measuring point P. Here, the formula α=arctan(Y2-Y1) / (X2-X1) is mainly used to calculate the azimuth angle α of the measuring point P in the relative coordinate system (such as Figure 4 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: Remotely control the monitoring equipment to perform calibration measurements, compare and verify the current measurement values ​​with historical measurement values, and confirm that they are correct. The monitoring equipment then resumes normal operation.

[0048] Finally, it should be noted that the above 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 aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
