Description

Technical Field

[0001] The invention belongs to the technical field of surveying and mapping instruments, and in particular relates to a surveying and mapping device for national land space planning. Background Art

[0002] Accurate topographic measurement is crucial in national land space planning. As a key measuring device, the total station can quickly obtain geographic spatial information by integrating angle measurement, distance measurement and data processing functions, providing a detailed data basis for national land space planning, ensuring the scientificity and rationality of the planning, and helping to rationally layout various types of land and facilities.

[0003] At present, before using the total station, it is generally necessary to calibrate, such as horizontal calibration. Secondly, the temperature, humidity, air pressure and other information of the measuring point need to be input into the total station. The total station uses an algorithm to compensate for the influence of factors such as temperature, humidity and air pressure on the detection accuracy of the total station (for example, the change of air pressure will change the density of the air. Since the distance measurement of the total station is based on the propagation of electromagnetic waves in the air, the change of air density will affect the propagation speed of electromagnetic waves, causing errors in the measured distance), thereby improving the accuracy of the data provided for national land space planning, such as the gyro total station disclosed in patent announcement number CN111141266B; Although the temperature, humidity, air pressure and other information are input into the control terminal of the total station before using it, the control terminal can use its own model algorithm to make up the difference based on the input data to improve the detection accuracy of the total station. However, during the detection process of the total station, if the environment changes significantly, such as excessive increase in humidity in the air, etc., it may cause a large deviation between the data at the time of detection and the pre-input data, which will still affect the detection accuracy. Secondly, when measuring an area, the total station needs to perform multi-point detection. For areas with changeable environments (such as mountainous areas), the environment in the same area may change significantly at different detection time points. If the staff re-compares whether the environment between the detection points has changed significantly before detecting each detection point, and then determines whether to re-enter the parameters into the total station, it will not only increase the cumbersomeness of use, but also be affected by the subjective consciousness of the staff, and may result in incorrect judgment of the amount of environmental changes between the detection points, thereby affecting the surveying and mapping effect of the total station.

[0023] The automatic leveling unit 14 is installed between the base 1 and the support unit 4. The automatic leveling unit 14 works according to the electrical signal output by the tilt detection unit 13 to the controller 3.

[0024] A hollow block 15 is fixedly installed on the side wall of the total station body 2, and a connecting hose 16 is fixedly plugged into the side wall of the hollow block 15, and the connecting hose 16 is connected to the exhaust chamber 9.

[0025] A flexible magnetic isolation sleeve 18 is fixedly installed at the bottom outer edge of the magnetic isolation support seat 43 and the top outer edge of the base 1, and the inner magnetic isolation ring 141 and the outer magnetic isolation ring 142 are both arranged inside the flexible magnetic isolation sleeve 18. The flexible magnetic isolation sleeve 18 can prevent foreign objects from getting stuck between the magnetic isolation support seat 43 and the base 1.

[0026] The operating principle of the present invention is now described as follows: the entire device is moved to a pre-set detection point, and then a tripod support is installed at the detection point, and the base 1 is installed on the top of the tripod support (the bottom of the base 1 is provided with a connecting member connected to the tripod support, such as a bolt or other member, and the tripod support is used to support the base 1), and then the total station body 2 is aligned with the center of the detection point (the bottom of the base 1 is provided with an infrared spotlight, which is convenient for personnel to align the total station body 2 with the center of the detection point), and then the controller 3 is started; After the controller 3 is started, the air pump 8 will be started immediately. The suction end of the air pump 8 will suck the external airflow through the air inlet cavity 5 and the air inlet hole 7, and input it into the round cover 131. Then, the airflow enters the inside of each round sleeve 132. Under the pressure of the airflow, each insulating counterweight block 138 is pushed to the side away from the round cover 131 for a certain distance, and then the airflow is discharged through the round sleeve 132. After the insulating counterweight block 138 moves to the side away from the round cover 131, each supporting spring 137 is compressed for a certain distance. When the base 1 is tilted, the insulating counterweight block 138 in the round sleeve 132 at a high position is compressed. Under the action of gravity, the conductive column 135 on the same side will move back a distance to one side of the circular cover 131, and the insulating counterweight block 138 in the circular sleeve 132 on the lower side will move a distance away from the circular cover 131 again under the action of gravity. After the controller 3 is started, the connection circuits of each arc-shaped electromagnetic plate 144 and the corresponding conductive column 135 and the conductive ring 134 will be synchronously connected. When the base 1 is tilted, the conductive column 135 in the circular sleeve 132 at a high position has moved back a distance to the circular cover 131, so the conductive column 135 at a high position is connected to the same side. The length of the connection loop between the conductive ring 134 and the arc-shaped electromagnetic plate 144 becomes longer. At this time, the connection loop resistance of the conductive column 135, the conductive ring 134 and the arc-shaped electromagnetic plate 144 becomes larger, so the current passed into the arc-shaped electromagnetic plate 144 becomes smaller. Similarly, the current passed into the arc-shaped electromagnetic plate 144 corresponding to the conductive column 135 at the lower position becomes larger. At this time, the arc-shaped electromagnetic plates 144 at the lower position have a larger magnetic thrust on the same-side permanent magnets 145 due to the larger current passed, while the arc-shaped electromagnetic plates 144 at the higher position have a smaller magnetic thrust on the same-side permanent magnets 145, thereby When the base 1 is tilted, the total station body 2 can be automatically leveled to keep the total station body 2 horizontal (the top of the tripod support frame should be kept as horizontal as possible when initially placed to ensure that the tilt angle of the base 1 and the total station body 2 is not greater than 15° when initially placed). At the same time, during the subsequent operation of the total station body 2, even if the total station body 2 is tilted (for example, due to soft soil, the tripod support frame slightly settles, causing the total station body 2 to tilt), the total station body 2 can still remain horizontal under the action of each arc-shaped electromagnetic plate 144; When the controller 3 starts the air pump 8, it will simultaneously start the environment detection component 6 (the environment detection component 6 includes a temperature detection probe, a humidity detection probe and an air pressure detection probe). The environment detection component 6 can detect the air entering the air inlet cavity 5, and convert the temperature, humidity and air pressure of the air into electrical signals and output them to the controller 3. The controller 3 converts the temperature, humidity and air pressure into data and displays them. The staff adjusts the detection parameters of the total station body 2 according to the corresponding data to reduce the influence of temperature, humidity and air pressure on the measurement accuracy (for example, for the electromagnetic wave ranging of the total station body 2, temperature changes will affect the propagation speed of the electromagnetic wave. The correction value of the electromagnetic wave propagation speed at different temperatures can be calculated by a formula, and then the measured distance is corrected, so as to reduce the influence of temperature on the ranging result); At the same time, each detection probe of the environmental detection component 6 will also convert the temperature, humidity, and air pressure into electrical signals and output them to the controller 3, and the controller 3 will amplify the electrical signals output by each detection probe of the environmental detection component 6 in proportion and output them to the corresponding normally open solenoid valve 104 and normally closed solenoid valve 105 (for example, when the ambient temperature is higher, the resistance of the thermistor inside the temperature detection probe decreases, so the electrical signal output by the temperature detection probe to the controller 3 becomes larger, and the current input to the corresponding normally open solenoid valve 104 and normally closed solenoid valve 105 becomes larger), and when the normally open solenoid valve 104 is energized, its valve plate is adsorbed, and the greater the current passed, the greater the degree of adsorption and closure of the valve plate. When the normally closed solenoid valve 105 is energized, its valve plate will also be adsorbed, and the greater the current passed, the greater the degree of adsorption and opening of the valve plate. The airflow input into the cavity 11 through each circular sleeve 132 will be discharged into the exhaust cavity 9 through each main vent hole 102 and the auxiliary vent hole 103, and the airflow passing through the normally closed solenoid valve 105 will be discharged through the exhaust pipe 101, and the gas flow rate detector 106 can detect the flow rate of the airflow in real time, and convert the detected gas flow rate into an electrical signal and output it to the controller 3, and the controller 3 will proportionally amplify the electrical signal output by the gas flow rate detector 106 and pass it to the electric push rod 121, and the electric push rod 121 can drive the left insulating plate 122 moves up, and after the electric push rod 121 works for 5 seconds, the controller 3 controls the electric push rod 121 to stop working (within the 5 seconds of the electric push rod 121 working at a fixed time, the greater the strength of the electric signal output by the gas flow rate detector 106 to the controller 3, the greater the current passed into the electric push rod 121, so in the same time, the electric push rod 121 pushes the left insulating plate 122 to move up a greater distance), at the same time, the controller 3 amplifies the electric signal output by the gas flow rate detector 106 in proportion and passes it to the electromagnetic push rod 124. Since the parameters of the gas environment are not easy to change significantly within 5 seconds, the electromagnetic push rod 124 pushes the right insulating plate 125 to move up, and the right insulating plate 1 The height of the upward movement of 25 is similar to the height of the left insulating plate 122, so that the conductive rod 126 and the conductive plate 123 are kept in contact. Therefore, after the controller 3 controls the electromagnetic push rod 124 to be energized, the controller 3 will receive the closed electrical signal of the connection loop between the conductive rod 126 and the conductive plate 123. During the operation of the total station body 2, if the gas environment changes significantly, the gas flow rate entering the exhaust pipe 101 through the auxiliary vent 103 will also change synchronously. At this time, the electrical signal output by the gas flow rate detector 106 to the controller 3 will also change synchronously, so the current passed to the electromagnetic push rod 124 will also change synchronously. When the current inside the electromagnetic push rod 124 changes too much (greater than or less than 0.5A), the height of the conductive rod 126 moving upward is too large or too small, so the conductive rod 126 will be separated from the conductive plate 123. At this time, the connection circuit between the conductive rod 126 and the conductive plate 123 is disconnected, so the connection circuit closing electrical signal between the conductive rod 126 and the conductive plate 123 received by the controller 3 is disconnected. At this time, the controller 3 will immediately alarm through its own alarm module. When the staff receives the alarm information, they should adjust the detection parameters of the total station body 2 in time to make the total station body 2 re-detect and ensure the accuracy of the detection result (when the total station body 2 works again, the controller 3 first controls the electric push rod 121 to work, so that its telescopic end moves back, and after the travel switch installed on the telescopic end detects that the telescopic end moves back and resets, the electric push rod 121 is controlled to stop working, and then each component is controlled to re-execute the above steps);. Secondly, when moving from one detection point to the next detection point for detection, after the detection work of the current detection point is completed, press the standby button of the controller 3, and when reaching the next detection point, resume the operation of the controller 3. At this time, the controller 3 re-controls the electromagnetic push rod 124 to work. If the environmental parameters at the two detection points do not change significantly, the conductive rod 126 will still be in contact with the conductive plate 123, so the controller 3 will still receive the closed electrical signal of the connection circuit between the conductive rod 126 and the conductive plate 123. At this time, there is no need to adjust the parameters of the total station body 2, and the detection can be started. If the closed electrical signal of the connection circuit between the conductive rod 126 and the conductive plate 123 is disconnected, the staff needs to readjust the parameters of the total station body 2 before the detection work can be carried out. Among them, the airflow entering the exhaust chamber 9 will be discharged into the hollow block 15 through the connecting hose 16, and finally discharged through the two heat exchange tubes 17. When passing through the heat exchange tubes 17, the cold airflow of the external air can exchange heat with the controller 3 and the power supply of the total station body 2, thereby assisting the cooling of the power supply of the controller 3 and the total station body 2, reducing the influence of the operating temperature of the controller 3 and the power supply on the detection accuracy of the total station body 2, and also improving the working stability of the total station body 2.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
