Description
Technical Field
[0001] The invention belongs to the field of field wire measurement methods for construction engineering, and in particular relates to a total station wire automatic measurement device and a measurement method. Background Art
[0002] At present, the mainstream layout forms of control network include traverse network and GNSS network, and traverse measurement mainly includes closed traverse, attached traverse and branch traverse. The main work of traverse measurement is to measure the angle and distance between control points.
[0003] Traditional angle and distance measurements are achieved by manual observation of total stations, which will introduce human observation errors during the manual observation process, which not only reduces efficiency but also increases human observation errors. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a total station wire automatic measurement device and a measurement method, which solves the problems of large errors, large data recording error rate and low work efficiency caused by manual observation during field measurement of traditional construction control networks in the prior art.
[0005] The present invention adopts the following technical solutions to solve the above technical problems:
[0006] A total station wire automatic measurement device comprises a motor-driven total station and a mobile terminal; the automatic total station obtains the observation angle and distance of each target prism and sends them to the mobile terminal; the mobile terminal automatically analyzes the observation angle and distance to obtain observation data.
[0007] Data is transmitted between the total station and the mobile terminal via Bluetooth.
[0008] The mobile terminal is provided with automatic analysis software for analyzing the data of the total station to obtain observation data.
[0009] A total station wire automatic measurement method comprises the following steps:
[0010] Step 1: Prepare the total station automatic traverse measuring device according to the project to be measured and perform initialization settings;
[0011] Step 2: The mobile terminal device performs self-learning based on the sample data of the initial detection, sets various parameters, and builds an automatic detection model;
[0012] Step 3: Automatic observation, cyclically observe the angles and distances of all the measurement rounds of the total station;
[0013] Step 4: Station verification: after all the rounds of measurement at the station are completed, the tolerance between the rounds is determined. If the tolerance is qualified, all the rounds of measurement data are recorded. If it is unqualified, one or more rounds of measurement are re-measured.
[0014] Step 5: Store data. When all measured data are qualified, save the observation data and close the total station to complete the measurement.
[0015] After the measurement in step 5 is completed, the data is sorted, the data of the mobile terminal is transferred to the computer, and then an adjustment file recognizable by the system is generated. The adjustment file is then adjusted and calculated. When the adjustment results are qualified, the adjustment results are output.
[0016] In step 1, the specific process of preparing the device is as follows:
[0017] According to the level of the project's traverse network, select a motor-driven total station that can meet the main axis measurement accuracy. If the instrument does not have Bluetooth communication function, use an external Bluetooth device and connect it to the total station via a data cable; then select a mobile terminal device with Bluetooth function and install the "Traverse Measurement Software" on the mobile terminal.
[0018] The specific process of initializing the device is as follows:
[0019] Set the communication parameters of the external Bluetooth device, and then set the communication mode on the total station to RS232 communication mode; after the Bluetooth settings are completed, open the mobile software to connect to Bluetooth. After the Bluetooth connection is successful, create a project in the software, create a file named after the survey station, and set various tolerances.
[0020] If the total station is equipped with a Bluetooth module, the Bluetooth setting is turned on to communicate directly with the Bluetooth of the mobile terminal.
[0021] In step 2, the mobile terminal performs self-learning and the specific steps of building an automatic detection model are as follows:
[0022] Aim the total station at the center of the target prism in the starting direction, and transmit the observation angle and distance to the software interface. Then aim at the centers of the target prisms in the remaining directions in turn, and transmit the observation angles and distances to the software interface in turn. When the observations of the first half of the survey in all directions are completed, the learning of the mobile device is completed, and the automatic detection model is obtained.
[0023] The target prisms are evenly arranged in different directions.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. With the help of a total station with motor rotation, through software programming and Bluetooth communication technology, automatic observation, automatic recording, automatic generation of adjustment files and then output of adjustment results can be achieved. This process can greatly reduce the increase in errors caused by human observation and the recording errors that may be caused by manual recording, which will greatly increase work efficiency and improve measurement accuracy.

This method can realize the automation and digitization of the entire process from field observation to indoor data, greatly reducing the errors of human observation and the problems of low efficiency and easy errors in human observation. All data are automated and digitized, greatly improving work efficiency and observation accuracy.

[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all of the embodiments.
[0033] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.
[0034] The invention provides a measuring method for automatic measurement of a total station wire, which solves the problems of large errors, large data recording error rate and low work efficiency caused by manual observation during field measurement of a traditional construction control network.
[0035] A total station traverse automatic measurement method uses a total station with an automatic collimation function and a mobile terminal device with a Bluetooth transmission function, and then establishes data communication between the two through Bluetooth communication technology, and then implements software to operate the total station to achieve automatic observation, automatic recording and other functions. The total station can use its own Bluetooth or an external Bluetooth device to achieve data communication.
[0036] The implementation of this method is divided into the following steps: A. Pre-survey preparation stage, B. Parameter setting of total station and mobile terminal equipment, C. Learning of mobile terminal equipment, D. Automatic observation, E. Station verification, F. End of observation at the station, G. Internal data sorting.
[0037] A total station wire automatic measurement device comprises a motor-driven total station and a mobile terminal; the automatic total station obtains the observation angle and distance of each target prism and sends them to the mobile terminal; the mobile terminal automatically analyzes the observation angle and distance to obtain observation data.
[0038] Specific embodiments, such as Figure 1 As shown,
[0039] A total station wire automatic measurement device comprises a motor-driven total station 1 and a mobile terminal 2; the automatic total station 1 obtains the observation angle and distance of each target prism and sends them to the mobile terminal 2; the embodiment comprises three target prisms, namely a first prism 3, a second prism 4, and a third prism 5; the mobile terminal 2 automatically analyzes the observation angle and distance to obtain observation data.
[0040] Data is transmitted between the total station and the mobile terminal via Bluetooth.
[0041] The mobile terminal is provided with automatic analysis software for analyzing the data of the total station to obtain observation data.
[0042] A total station wire automatic measurement method comprises the following steps:
[0043] Step 1: Prepare the total station automatic traverse measuring device according to the project to be measured and perform initialization settings;
[0044] Step 2: The mobile terminal device performs self-learning based on the sample data of the initial detection to build an automatic detection model;
[0045] Step 3: Automatic observation, cyclically observe the angles and distances of all the measurement rounds of the total station;
[0046] Step 4: Station verification: after all the rounds of measurement at the station are completed, the tolerance between the rounds is determined. If the tolerance is qualified, all the rounds of measurement data are recorded. If it is unqualified, one or more rounds of measurement are re-measured.
[0047] Step 5: Store data. When all measured data are qualified, save the observation data and close the total station to complete the measurement.
[0048] Specific embodiments, such as Figure 2 , Figure 3 As shown,
[0049] This example takes a plant control network re-survey project as an example. In the plant control network re-survey project, the wire network is arranged in three levels, namely the main axis, the first-level network and the second-level network. The main axis needs to observe 6 rounds, with 31 control points, the first-level network needs to observe 4 rounds, with 89 control points, and the second-level network needs to observe 2 rounds, with 54 control points. Because the observation process of all stations is the same, this embodiment only describes one station in the main axis.
[0050] Step 1: Preparation before testing
[0051] Because the project's wire network is divided into three levels, in order to ensure the measurement accuracy, this time we chose a high-precision motor-driven Sokkia NET05 total station that can meet the main axis measurement accuracy. This instrument does not have Bluetooth communication function, so this time we chose an external Bluetooth device and connected it to the total station via a data cable. Then we chose an Android phone with Bluetooth as the mobile terminal device, and installed the "wire measurement software" on the Android phone.
[0052] Step 2: Total station and mobile terminal equipment parameter settings
[0053] Because an external Bluetooth device is used, you only need to set the communication parameters of the external Bluetooth device, and then set the communication mode on the total station to RS232. After the Bluetooth setting is completed, open the mobile software to connect to the Bluetooth. After the Bluetooth connection is successful, you can create a project in the software, create a file named after the station name, and set the tolerances of the main axis.
[0054] Step 3: Mobile terminal device learning
[0055] After the parameters are set, aim the total station at the center of the target prism in the starting direction, and transmit the observation angle and distance to the software interface. Then aim at the remaining directions. When the observation of the second half of the survey in all directions is completed, the learning of the mobile device is completed. After the learning is completed, an automatic detection model is generated.
[0056] Step 4: Automatic Observation
[0057] After the software learning is completed, you can use the software to control the total station to complete the angle and distance observations of the remaining rounds. After completing a round, the software will automatically perform various limit error judgments. When the limit error meets the requirements, the software will automatically proceed to the next round of observation until all rounds are observed.
[0058] Step 5: Station Verification
[0059] When all the measurement rounds of the measuring station are completed, the software will make a limit difference judgment between each measurement round. When the limit difference is qualified, all the measurement round data can be recorded. If it is not qualified, the software will re-measure one or more measurement rounds according to the user's requirements.
[0060] Step 6: End the observation of this station
[0061] When all the measured data are qualified, the user saves the observed data, turns off the total station, moves to the next observation point, and repeats the observation work of one station.
[0062] Step 7: Internal data organization
[0063] After completing all the measuring stations of the main axis in the control network, transfer the data of the mobile terminal to the computer, and then use the self-developed "control network data processing software" to generate an adjustment file that can be recognized by Southern Adjustment Easy, and then import the adjustment file into Southern Adjustment Easy for rigorous adjustment calculation. When the adjustment results are qualified, output the adjustment results.
[0064] If the total station is equipped with a Bluetooth module, the Bluetooth setting is turned on to communicate directly with the Bluetooth of the mobile terminal.
[0065] The target prisms are evenly arranged in different directions.
