Description

Technical Field

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

[0002] In territorial space planning, accurate topographic surveying is crucial. As a key surveying device, the total station can quickly obtain geospatial information by integrating angle measurement, distance measurement, and data processing functions, providing a detailed data basis for territorial space planning, ensuring the scientificity and rationality of the planning, and helping to rationally layout various types of land uses and facilities.

[0003] Currently, before using the total station, it generally needs to be calibrated, such as horizontal calibration. Secondly, information such as the temperature, humidity, and air pressure of the measurement point needs to be input into the total station. The total station compensates for the influence of factors such as temperature, humidity, and air pressure on the detection accuracy of the total station through algorithms (for example, the change in air pressure will change the density of the air. Since the total station ranging is based on the propagation of electromagnetic waves in the air, and the change in air density will affect the propagation speed of electromagnetic waves, resulting in an error in the measured distance), thereby improving the data accuracy provided for territorial space planning. For example, the gyro total station disclosed in Patent Publication No. CN111141266B;

[0004] Although before using the total station, information such as temperature, humidity, and air pressure is input into the control terminal of the total station, and its control terminal can perform compensation through its own model algorithm 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 an excessive increase in the humidity in the air, etc., it may cause a large deviation between the detected data and the pre-input data, still affecting the detection accuracy. Secondly, when the total station measures an area, it needs to perform multi-point detection. For an area with a changing environment (such as a mountainous area), 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 each detection point and then determines whether to re-input parameters into the total station, it will not only increase the usage complexity, but also be affected by the subjective awareness of the staff, and there may be a phenomenon of misjudging the environmental change amount between the detection points, thus affecting the surveying and mapping effect of the total station.

[0032] The intake chamber 5 is opened inside the base 1. An environment detection component 6 is installed inside the intake chamber 5.

[0033] A cavity 11 is opened above the exhaust chamber 9 inside the base 1. The air outlet end of the air pump 8 is communicated with the cavity 11. The impedance adjustment mechanism 10 is communicated with the exhaust chamber 9. A recording trigger mechanism 12 is installed inside the exhaust chamber 9. The recording trigger mechanism 12 includes an electric push rod 121 fixedly installed inside the exhaust chamber 9, and a left insulating plate 122 is installed at the telescopic end of the electric push rod 121. A conductive plate 123 is fixedly installed at the end of the left insulating plate 122. An electromagnetic push rod 124 is installed at a position on one side of the electric push rod 121 inside the exhaust chamber 9, and a right insulating plate 125 is installed at the telescopic end of the electromagnetic push rod 124. A conductive rod 126 is fixedly installed at the end of the right insulating plate 125, and the rod end of the conductive rod 126 is in sliding contact with the side wall of the conductive plate 123.

When the electric push rod 121 works regularly for 5 seconds and a certain amount of current is passed through, the height that the left insulating plate 122 is pushed up is the same as the height that the right insulating plate 125 is pushed up when the electromagnetic push rod 124 passes through the same amount of current.

[0034] The tilt detection unit 13 is installed inside the cavity 11, and the tilt detection unit 13 is used to detect the levelness of the base 1. The tilt detection unit 13 includes a round cover 131 fixedly installed on the lower cavity wall of the cavity 11, and the round cover 131 is communicated with the air outlet end of the air pump 8. A plurality of round sleeves 132 are fixedly inserted on the side wall of the round cover 131, and an insulating ring 133 is fixedly installed inside each round sleeve 132.

[0035] 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. The automatic leveling unit 14 includes an inner magnetic isolation ring 141 and an outer magnetic isolation ring 142 fixedly installed on the top of the base 1, and the inner magnetic isolation ring 141 is arranged inside the outer magnetic isolation ring 142. Rubber support rings 143 are fixedly arranged between the inner magnetic isolation ring 141 and the outer magnetic isolation ring 142 and the magnetic isolation support seat 43. A plurality of arc-shaped electromagnetic plates 144 evenly distributed in a ring are fixedly installed at the position between the inner magnetic isolation ring 141 and the outer magnetic isolation ring 142 on the top of the base 1. A plurality of permanent magnets 145 corresponding to the positions of the arc-shaped electromagnetic plates 144 are fixedly installed at the bottom of the magnetic isolation support seat 43. Each conductive column 135 and the conductive ring 134 on the same side are electrically connected to the corresponding arc-shaped electromagnetic plate 144 through the controller 3. After the arc-shaped electromagnetic plate 144 is energized, under the action of the repulsion between the same-sex poles, it can push the permanent magnet 145 to move upward.

[0036] A hollow block 15 is fixedly installed on the side wall of the total station body 2. A connecting hose 16 is fixedly inserted on the side wall of the hollow block 15, and the connecting hose 16 is communicated with the exhaust cavity 9. Two heat exchange tubes 17 are fixedly inserted on the side wall of the hollow block 15 far from the connecting hose 16. One heat exchange tube 17 is in contact with the shell of the controller 3, and the other heat exchange tube 17 is in contact with the shell of the power supply end of the total station body 2, so as to dissipate heat and cool down the power supply of the total station body 2 and the controller 3.

[0037] A flexible magnetic isolation sleeve 18 is fixedly installed together at the outer edge of the bottom of the magnetic isolation support seat 43 and the outer edge of the top 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.

[0038] The operating principle of the present invention is described as follows: Move the entire device to a preset detection point. Subsequently, install a three-legged support frame at the detection point, and install the base 1 on the top of the three-legged support frame (a connecting member for connecting with the three-legged support frame, such as a bolt or other components, is provided at the bottom of the base 1, and the three-legged support frame is used to support the base 1). Then, align the total station body 2 with the center of the detection point (an infrared spotlight is provided at the bottom of the base 1 to facilitate the alignment of the total station body 2 with the center of the detection point). Subsequently, start the controller 3;

[0039] After the controller 3 is started, the air pump 8 will be immediately started. The suction end of the air pump 8 sucks in the external air flow through the air inlet cavity 5 and the air inlet hole 7 and inputs it into the inside of the round cover 131. Subsequently, the air flow enters the inside of each round sleeve 132. Under the pressure of the air flow, each insulating counterweight 138 is pushed a certain distance to the side away from the round cover 131. Then the air flow is discharged through the round sleeve 132. After the insulating counterweight 138 moves to the side away from the round cover 131, each support spring 137 is compressed by a certain distance. When the base 1 is in an inclined state, the insulating counterweight 138 in the round sleeve 132 at the higher position will move a certain distance back to the side of the round cover 131 under the action of gravity for the conductive column 135 on the same side. And the insulating counterweight 138 in the round sleeve 132 at the lower side will move a certain distance away from the round cover 131 again under the action of gravity for the conductive column 135 on the same side. After the controller 3 is started, the connection circuits between each arc-shaped electromagnetic plate 144 and the corresponding conductive column 135 and the conductive ring 134 will be synchronously connected. In the state where the base 1 is inclined, since the conductive column 135 in the round sleeve 132 at the higher position moves back a certain distance to the round cover 131, the length of the conductive column 135 at the higher position connected to the connection circuit between the conductive ring 134 and the arc-shaped electromagnetic plate 144 on the same side becomes longer. At this time, the resistance of the connection circuit of the conductive column 135, the conductive ring 134 and the arc-shaped electromagnetic plate 144 becomes larger, so the current flowing into the inside of the arc-shaped electromagnetic plate 144 becomes smaller. Similarly, the current flowing into the arc-shaped electromagnetic plate 144 corresponding to the conductive column 135 at the lower position becomes larger. At this time, since the current flowing into each arc-shaped electromagnetic plate 144 at the lower position becomes larger, the magnetic thrust of the arc-shaped electromagnetic plate 144 on the permanent magnet 145 on the same side becomes larger, while the magnetic thrust of the arc-shaped electromagnetic plate 144 at the higher position on the permanent magnet 145 on the same side becomes smaller. Thus, when the base 1 is in an inclined state, it can automatically level the total station body 2 so that the total station body 2 remains horizontal (when the tripod support is initially placed, its top should be kept as horizontal as possible to ensure that the inclination angle of the base 1 and the total station body 2 at the initial placement is not greater than 15°). At the same time, during the subsequent operation of the total station body 2, even if the total station body 2 is inclined (for example, due to soft soil, the tripod support has a slight settlement, resulting in the inclination of the total station body 2), under the action of each arc-shaped electromagnetic plate 144, the total station body 2 can still remain horizontal;

[0040] When the controller 3 starts the air pump 8, it will simultaneously start the environmental detection component 6 (the environmental detection component 6 includes a temperature detection probe, a humidity detection probe, and a barometric pressure detection probe). The environmental detection component 6 can detect the air entering the interior of the intake chamber 5 and convert the temperature, humidity, and barometric pressure of the air into electrical signals and output them to the controller 3. The controller 3 then converts the temperature, humidity, and barometric pressure into data and displays it. The staff can adjust the detection parameters of the total station body 2 according to the corresponding data to reduce the influence of temperature, humidity, and barometric pressure on the measurement accuracy (for example, for the electromagnetic wave distance measurement of the total station body 2, the change in temperature will affect the propagation speed of the electromagnetic wave. The correction value of the electromagnetic wave propagation speed at different temperatures can be calculated through a formula, and then the measured distance can be corrected, thereby reducing the influence of temperature on the ranging result).

[0041] Meanwhile, each detection probe of the environmental detection component 6 also converts the temperature, humidity, and air pressure into electrical signals and outputs them to the controller 3. The controller 3 then amplifies the electrical signals output by each detection probe of the environmental detection component 6 proportionally and outputs them to the corresponding normally open solenoid valve 104 and normally closed solenoid valve 105 (for example, when the environmental temperature is higher, the resistance of the thermosensitive element 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 into the corresponding normally open solenoid valve 104 and normally closed solenoid valve 105 becomes larger). When the normally open solenoid valve 104 is energized, its valve plate is adsorbed, and the greater the current passed through, the greater the degree of adsorption and closure of its valve plate. When the normally closed solenoid valve 105 is energized, its valve plate is also adsorbed, and the greater the current passed through, the greater the degree of adsorption and opening of its 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 ventilation hole 102 and auxiliary ventilation hole 103. The airflow passing through the normally closed solenoid valve 105 will be discharged through the exhaust pipe 101. The gas flow velocity detector 106 can detect the flow velocity of the airflow in real time and convert the detected gas flow velocity into an electrical signal and output it to the controller 3. The controller 3 then amplifies the electrical signal output by the gas flow velocity detector 106 proportionally and inputs it to the electric push rod 121. The electric push rod 121 can drive the left insulating plate 122 to move upward. After the electric push rod 121 works regularly for 5 seconds, the controller 3 controls the electric push rod 121 to stop working (during the 5 seconds when the electric push rod 121 works regularly, the greater the intensity of the electrical signal output by the gas flow velocity detector 106 to the controller 3, the greater the current input into the electric push rod 121. Therefore, within the same time, the greater the distance that the electric push rod 121 pushes the left insulating plate 122 upward). Meanwhile, the controller 3 amplifies the electrical signal output by the gas flow velocity detector 106 proportionally and inputs it to the electromagnetic push rod 124. Since the parameters of the gas environment are not likely to change significantly within 5 seconds, the electromagnetic push rod 124 pushes the right insulating plate 125 upward, and the height that the right insulating plate 125 moves upward is similar to the height of the left insulating plate 122, making the conductive rod 126 keep in contact with the conductive plate 123. 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 circuit 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 ventilation hole 103 will also change synchronously. At this time, the electrical signal output by the gas flow velocity detector 106 to the controller 3 will also change synchronously. Therefore, the current input into the electromagnetic push rod 124 will also change synchronously. When the current change in the electromagnetic push rod 124 is too large (greater than or less than 0.When the height of the conductive rod 126 moving upward is too large or too small at 5A), the conductive rod 126 will separate from the conductive plate 123. At this time, the connection circuit between the conductive rod 126 and the conductive plate 123 is disconnected. Therefore, the controller 3 receives a disconnection of the closed electrical signal of the connection circuit between the conductive rod 126 and the conductive plate 123. At this time, the controller 3 will immediately alarm through its own alarm module. When the staff receives the alarm information, they should timely adjust the detection parameters of the total station body 2 to make the total station body 2 perform the detection work again to 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. After detecting that the telescopic end moves back and resets through the travel switch installed on the telescopic end, the controller 3 controls the electric push rod 121 to stop working. Subsequently, control each component to re - execute the above steps).

[0042] Secondly, when moving from one detection point to the next for detection, after the detection work at the current detection point is completed, press the standby key of the controller 3. When reaching the next detection point, resume the work of the controller 3. At this time, the controller 3 controls the electromagnetic push rod 124 to work again. 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. Therefore, 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, the parameters of the total station body 2 do not need to be adjusted to start the detection. 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 re - adjust the parameters of the total station body 2 before they can start the detection work;

[0043] Among them, the air flow entering the exhaust cavity 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 the cold air flow of the external air passes through the heat exchange tubes 17, it can exchange heat with the power supplies of the controller 3 and the total station body 2, thereby being able to assist in cooling the power supplies of the controller 3 and the total station body 2, reducing the influence of the working 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.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
