[0002] Currently, my country has nearly 40,000 kilometers of high-speed railways (hereinafter referred to as HSR) in operation. In the operation and maintenance of railway tracks, precision control networks serve as the benchmark for track maintenance operations, and regular re-survey is essential. However, the characteristics of HSR operating lines determine that field measurement work in the re-survey of precision control networks can only be carried out at railway window points. Usually, the railway window time for HSR is 240 minutes in principle.

[0003] In the prior art, the measurement method of the precision control network of the high-speed railway operating line usually adopts conventional measurement means, that is, the mode of professional technicians + tripods + total stations. The specific operation process is as follows: 1. The technician carries the total station, tripod, and temperature barometer to the site; 2. The technician sets up the instrument, then manually levels the instrument and sets the temperature and pressure parameters of the total station by measuring the environmental parameters; 3. The technician enters the point number of the observation target point and manually enters some target points to complete the positioning of the total station; 4. The technician operates the measurement software of the total station to automatically complete the measurement work of a single station; 5. The technician carries the total station, tripod and other accessories, and transports them to the next site to repeat the above measurement method. Since the above-mentioned measurement operation needs to rely on technicians and requires frequent installation and transportation of equipment, this leads to a contradiction that is difficult to coordinate between the extremely short construction window time and the huge workload, resulting in the measurement work requiring huge manpower and material resources and occupying a large amount of social resources.

[0015] The above-mentioned automatic measurement system for railway precision control network is used. Specifically, in the actual use process, the station measurement operation of the railway precision control network should be carried out during the railway skylight time period. Specifically, the base is lifted and placed on the high-speed railway track and the track wheels on both sides are pressed against the track surface of the corresponding sides respectively, so that the external handheld computer is wirelessly connected to the control host in the main control box body through the wireless and Bluetooth control module, and then the existing data is imported into the control host through the external handheld computer and the hardware parameters of the control host are set through the handheld computer. The existing data generally includes the existing control network coordinate data and line parameter data. Specifically, it is necessary to set the hardware parameters according to the existing The walking distance of the walking robot assembly is set according to the data data so that the walking robot assembly can accurately walk to the preset station observation point for measurement operation. After the walking robot assembly drives the base and the total station body and other components to move to the preset station measurement position, the control host is controlled by the handheld computer to initialize the total station body and the correction sensor assembly system, and then the measurement operation is started. During the measurement operation, the total station body is corrected for the meteorological environment in real time through the feedback control loop composed of the temperature sensor, the pressure sensor, the control host and the total station body, so that the meteorological environment parameters of the total station body are adjusted according to the specific setting station.

The four corners of the bottom surface of the base 2 are vertically fixed with wheel seats 303, and the inner end surfaces of the wheel seats 303 at both sides are opposite to each other and are laterally fixed with drive motors 305. The motor shafts 307 of the drive motors 305 pass through the corresponding wheel seats 303 in a rotationally matched manner and are coaxially fixed with rail wheels 301 at the ends. The wheelbase between the rail wheels 301 at both sides is consistent with the track gauge of the railway track, so that the rail wheels 301 at both sides can move along the railway track after being pressed on the two side tracks of the railway. The track rolls linearly, and the inner end surfaces of the wheel seats 303 on both sides that are opposite to each other are installed with speed encoder bodies 304 beside the drive motor 305, and the speed encoder bodies 304 are electrically connected to the corresponding drive motors 305, so as to detect and control the driving distance of the track wheel 301 by the drive motor 305 through the speed encoder body 304. Such a setting makes it convenient to detect and control the drive motor 305 through the speed encoder body 304, and then quantitatively control the rolling distance of the track wheel 301 by detecting and regulating the working time of the drive motor 305, so as to realize the function of allowing the walking robot component 3 to drive the base 2 to accurately move to the preset station measurement position. Preferably, lifting handles as shown in the figure can be extended and installed on both sides of the base 2 to facilitate the staff to lift the base 2 onto the rail track as a force application point and to lift the base 2 off the rail track later.

[0022] See also Figure 5 and Figure 6As shown, a disassembly assembly 6 is installed in the middle of the top surface of the base 2, and a mounting seat 7 is fixed horizontally on the top of the disassembly assembly 6. The top surface of the mounting seat 7 is installed with a total station body 1 for performing precise control network data measurement operations on the measurement position of the set site, and the mounting seat 7 and the total station body 1 are detachably fixed to the top of the base 2 through the disassembly assembly 6. Specifically, the disassembly assembly 6 includes a matching seat 605 and a fixing sleeve 601. Matching seats 605 are vertically fixed on both sides of the bottom surface of the mounting seat 7, and the matching seats 605 at both sides are away from each other. The side end surfaces are provided with limiting holes 608 in the horizontal direction. The top surface of the base 2 is vertically fixed with fixing sleeves 601 on both sides below the mounting seat 7, and the top surface of the fixing sleeves 601 is vertically provided with matching grooves 604. The matching grooves 604 correspond to the matching seats 605 one by one and are vertically slidably matched. The outer end surfaces of the fixing sleeves 601 at both sides are away from each other and are provided with mounting holes 607 in the horizontal direction. The mounting holes 607 are vertically connected to the corresponding matching grooves 604, and the mounting holes 607 are horizontally coaxial with the corresponding limiting holes 608. The mounting holes 607 are The limiting rods 606 are coaxially slidably matched along the transverse direction, and the inner ends of the limiting rods 606 at both sides that are close to each other are slidably matched with the corresponding limiting holes 608 at the transverse direction, and the outer ends of the limiting rods 606 at both sides that are away from each other extend out of the outer end surface of the corresponding fixing sleeve 601 and are coaxially fixed with the handle 603. The part of the limiting rod 606 located between the corresponding handle 603 and the outer end surface of the fixing sleeve 601 is coaxially gap-matched with a spring 602, and the two ends of the spring 602 are fixedly connected to the corresponding handle 603 and the outer end surface of the fixing sleeve 601 respectively. Then, with such a setting, the mounting seat 7 and the total station body 1 can be quickly and detachably fixed to the top of the base 2 by means of vertical sliding cooperation between the matching seat 605 and the matching groove 604 and horizontal sliding cooperation between the limiting rod 606 and the limiting hole 608. At the same time, the mounting seat 7 and the total station body 1 can be detached from the top of the base 2 by simply pulling the limiting rod 606 out of the limiting hole 608. It should be noted that when the limiting rod 606 and the limiting hole 608 are disengaged, the handheld handle 603 is pulled outward and stretched by the spring 602, which can be completed smoothly.

[0023] See also Figure 1 and Figure 5As shown, a correction sensor assembly 4 for correcting meteorological environmental parameters of the total station body 1 is installed on the front of the top surface of the base 2. Specifically, the correction sensor assembly 4 includes a protective box body 401 and an insulating bottom plate 406. The protective box body 401 is fixedly installed on the front of the top of the base 2. The bottom of the protective box body 401 is unfolded and fixed with an insulating bottom plate 406. Preferably, the insulating bottom plate 406 is a hard resin plate and has a plurality of holes on the surface, so that the level sensor 407, the temperature sensor 408 and the pressure sensor 409 can be fixed on the surface of the insulating bottom plate 406 by adding screws according to the holes, which can not only achieve a firm fixation of the level sensor 407, the temperature sensor 408 and the pressure sensor 409, but also provide stable electrical insulation protection for the level sensor 407, the temperature sensor 408 and the pressure sensor 409 through the insulating bottom plate 406, and the top surface of the insulating bottom plate 406 is sequentially installed with the level sensor 407, the temperature sensor 408 and the pressure sensor 409. The pressure sensor 409, the level sensor 407, the temperature sensor 408 and the pressure sensor 409 should be spaced a certain distance apart. If necessary, a partition can be installed between them to prevent interference with each other. In this way, since the level sensor 407, the temperature sensor 408 and the pressure sensor 409 are provided and are electrically connected to the control host 505 of the master control assembly 5 through wiring, the feedback control loop composed of the temperature sensor 408, the pressure sensor 409, the control host 505 and the total station body 1 can perform real-time meteorological environment correction on the total station body 1, thereby automatically adjusting the meteorological environment parameters of the total station body 1 to the parameters according to the specific measurement location of the station. At the same time, the feedback control loop composed of the level sensor 407, the control host 505 and the total station body 1 can perform real-time horizontal state correction on the total station body 1, thereby automatically adjusting the total station body 1 to a horizontal state according to the specific measurement location of the station.

[0024] See also Figure 1 and Figure 4As shown, a main control component 5 for regulating and controlling the walking robot component 3, the total station body 1 and the correction sensor component 4 is installed at the rear of the top surface of the base 2. Specifically, the main control component 5 includes a main control box body 501, a control host 505 and a power supply 506. The main control box body 501 is fixedly installed at the rear of the top surface of the base 2 and the rear is open. The control host 505 for regulating and controlling the walking robot component 3, the total station body 1 and the correction sensor component 4 and the power supply 506 for powering the walking robot component 3, the total station body 1 and the correction sensor component 4 are respectively installed on both sides of the inner bottom surface of the main control box body 501. 6. Such a configuration makes it easy to control the total station body 1; the driving motor 305 and the speed encoder body 304 of the walking robot assembly 3; the level sensor 407, the temperature sensor 408 and the air pressure sensor 409 of the correction sensor assembly 4 respectively through the control host 505, so as to smoothly allow the level sensor 407, the temperature sensor 408 and the air pressure sensor 409 to cooperate with the working state of the total station body 1 to complete the observation and measurement operation of the preset station measurement position, and at the same time smoothly allow the speed encoder body 304 and the driving motor 305 to cooperate with each other to complete the accurate walking of the base 2 to the preset station observation point.

[0025] As the preferred solution in this case, see Figures 1-6 As shown, the track wheels 301 at both sides are coaxially fixed with wheel flanges 302 at the outer periphery of the ends close to the inner edges of the corresponding railway tracks to prevent the track wheels 301 from derailing. Preferably, the wheel flanges 302 are in contact with the inner sides of the corresponding high-speed railway tracks, so that the wheel flanges 302 at both sides are respectively attached to the inner sides of the adjacent tracks and are stuck between the tracks at both sides, thereby guiding the rolling process of the track wheels 301 along the tracks and preventing the track wheels 301 from derailing. The outer end faces of the wheel seats 303 at both sides are opposite to each other and are fixed with bearing seats 306. The motor shafts 307 coaxially pass through the corresponding bearing seats 306 and are coaxially fixed to the inner rings of the bearings built into the corresponding bearing seats 306. Such an arrangement facilitates the stably supporting of the rotation of the motor shaft 307 by the built-in bearings by setting the bearing seats 306, which is beneficial to improving the movement smoothness of the rolling process of the track wheels 301.

[0026] See also Figure 1As shown, the correction sensor assembly 4 is further optimized. The top of the protective box body 401 is detachably closed with a box cover 402 by means of a physical snap 404, and a plurality of ventilation holes 403 are provided on the surface of the box cover 402. The purpose of such a setting is to be able to shield and protect the top of the protective box body 401 through the box cover 402, and at the same time, the setting of the ventilation holes 403 facilitates the level sensor 407, the temperature sensor 408 and the pressure sensor 409 in the protective box body 401 to smoothly obtain the external meteorological environment parameters; a wire opening 405 is provided on one side of the protective box body 401 for allowing the wiring cables to pass through, so that the wiring cables of the level sensor 407, the temperature sensor 408 and the pressure sensor 409 can pass through the wire opening 405 to the outside and smoothly extend to the control host 505.

[0027] See also Figure 2 and Figure 3As shown, the master control component 5 has been optimized to better meet the design requirements. The control host 505 is integrated with a wireless and Bluetooth control module 504 for remote connection with an external handheld computer. The purpose of this setting is that the external handheld computer can realize remote wireless control of the master control component 5, the walking robot component 3, the total station body 1 and the correction sensor component 4 by wirelessly connecting with the control host 505 through the wireless and Bluetooth control module 504, so as to facilitate the remote control of the speed encoder body 304 and the drive motor 305 of the walking robot component 3 to cooperate with each other to drive the base 2 to move to the set station measurement position, and at the same time facilitate the remote control of the total station body 1 and the level sensor 407, temperature sensor 408 and pressure sensor 409 of the correction sensor component 4 to cooperate with each other to complete the measurement operation. The power supply 506 is a replaceable battery pack and is integrated with a herringbone charging interface and a power supply 506 switch on the surface, so that the power supply 506 can be controlled to be on and off as a whole through the power supply 506 switch, which is convenient for turning on the power supply at the beginning and turning off the power supply at the end of the measurement. At the same time, the herringbone charging interface can also be used to charge and replenish the power supply 506 smoothly and conveniently. Moreover, since the power supply 506 is designed as a replaceable battery pack, it can be conveniently replenished by replacing the battery. Preferably, the power supply capacity of the power supply 506 should at least allow the walking robot component 3 to have a continuous range of more than 100km. The rear part of the main control box body 501 is provided with a door 503 which can be opened and closed repeatedly by a hinge, and the front and side parts of the main control box body 501 are respectively provided with wiring openings 502 for facilitating the smooth passage of wiring cables. This arrangement facilitates the opening and closing of the control host 505 and the power supply 506 and the maintenance thereof by opening and closing the door 503. At the same time, the wiring opening 502 is provided to facilitate the smooth passage of the wiring between the total station body 1 and the control host 505, and the wiring between the correction sensor assembly 4 and the control host 505 can also be smoothly passed through the wiring opening 502 to complete the setting.

[0028] See also Figure 12 As shown, the walking robot component 3, the correction sensor component 4 and the total station body 1 are all electrically connected to the general control component 5. Specifically, the speed encoder body 304 and the drive motor 305 of the walking robot component 3 are electrically connected to each other, and the speed encoder body 304 and the drive motor 305 are both electrically connected to the control host 505. At the same time, the horizontal sensor 407, the temperature sensor 408 and the air pressure sensor 409 of the correction sensor are respectively electrically connected to the total station body 1, and the horizontal sensor 407, the temperature sensor 408, the air pressure sensor 409 and the total station body 1 are all electrically connected to the control host 505, and the power supply 506 and the control host 505 are also electrically connected through wiring.

[0029] See also Figure 1 、 Figure 4 and Figure 5 As shown, the surface of the base 2 is optimized as follows when wiring is arranged. A wire trough box 8 is installed on one side of the top surface of the base 2 to facilitate the arrangement, storage and protection of the wiring cables, and the top of the wire trough box 8 is snap-fitted and closed with a trough cover 801. Preferably, the wire opening 405 and the wiring opening 502 are located on the same side and the wire trough box 8 is arranged on the side close to the wire opening 405 and the wiring opening 502. This arrangement facilitates the centralized arrangement and arrangement of the wiring passing through the wire opening 405 and the wiring opening 502 in the wire trough box 8, which not only straightens the wiring but also isolates and protects the wiring.

[0030] See also Figure 13As shown, with the above structure, specifically in the actual use process, the station measurement operation of the railway precision control network should be carried out during the railway skylight time period. Specifically, when carrying out the operation, the base 2 is lifted and placed on the high-speed railway track and the track wheels 301 on both sides are pressed against the track surface of the corresponding sides respectively, so that the external handheld computer is wirelessly connected to the control host 505 in the main control box body 501 through the wireless and Bluetooth control module 504, and then the existing data is imported into the control host 505 through the external handheld computer and the hardware parameters of the control host 505 are set through the handheld computer. The data generally include the existing control network coordinate data and line parameter data. Specifically, the walking distance of the walking robot component 3 is set according to the existing data so that the walking robot component 3 can accurately walk to the preset station observation point for measurement operation. After the walking robot component 3 drives the base 2 and the total station body 1 and other components to move to the preset station measurement position, the control host 505 is controlled by the handheld computer to initialize the total station body 1 and the correction sensor component 4 system, and then the measurement operation is started. During the measurement operation, the temperature sensor 408, the air pressure sensor 409 and the control host are used to control the total station body 1 and the correction sensor component 4 system. The feedback control loop composed of the host 505 and the total station body 1 performs real-time meteorological environment correction on the total station body 1, thereby automatically adjusting the meteorological environment parameters of the total station body 1 to the parameters according to the specific measurement location of the set station. At the same time, the feedback control loop composed of the level sensor 407 and the control host 505 and the total station body 1 performs real-time horizontal state correction on the total station body 1, thereby automatically adjusting the total station body 1 to the horizontal state according to the specific measurement location of the set station. Then, the handheld computer controls the total station body 1 through the control host 505 to automatically perform field data. Dynamic observation measurement, after the measurement is completed, it returns to the control host 505 for field data verification, and the verification result is displayed on the handheld computer. If the field data verification result is qualified, the data is stored in the control host 505 and the handheld computer is used again to control the control host 505 to make the walking robot component 3 drive the base 2 and the total station body 1 along the high-speed rail track to move to the next preset station observation point. If the field data verification result is unqualified, a second measurement should be carried out on the spot to verify again. If the verification result is still unqualified, it is necessary to assign professional personnel to arrive at the site and conduct problem troubleshooting and maintenance on the preset station observation point.

[0031] In the above scheme, since the total station body 1, the correction sensor assembly 4 and the master control assembly 5 are integrated on the top surface of the base 2, the time required for accessories during the measurement operation is reduced, and the efficiency of the precision control network measurement of the high-speed railway operating line is effectively improved, thereby achieving the purpose of saving manpower and material resources and improving social and economic benefits. Since a walking robot assembly 3 is installed at the bottom of the base 2, the driving motor 305 of the walking robot assembly 3 drives the track wheel 301 to roll along the rail and the speed encoder body 304 matches the existing control network coordinate data and line parameter data to drive the base 2 to move smoothly to the set-point measurement position, replacing the traditional situation where technicians perform total station positioning at the set-point. The operation mode is conducive to simplifying the measurement operation process and improving the measurement operation efficiency. At the same time, since the correction sensor assembly 4 on the top surface of the base 2 is integrated with the level sensor 407, the temperature sensor 408 and the air pressure sensor 409 during the measurement process, the total station body 1 can be corrected for the meteorological environment in real time through the feedback control loop composed of the temperature sensor 408, the air pressure sensor 409, the control host 505 and the total station body 1, so that the meteorological environment parameters of the total station body 1 are automatically adjusted to the parameters according to the specific measurement position of the set site. At the same time, the level state of the total station body 1 can be corrected in real time through the feedback control loop composed of the level sensor 407, the control host 505 and the total station body 1. The total station body 1 is automatically adjusted to a horizontal state according to the specific measurement position of the set station, which effectively improves the accuracy problem in the measurement process. When it comes to the installation and setting of the total station body 1, the mounting seat 7 and the total station body 1 can be quickly and detachably fixed to the top of the base 2 by means of the vertical sliding cooperation of the matching seat 605 and the matching groove 604 and the horizontal sliding cooperation of the limit rod 606 and the limit hole 608. The mounting seat 7 and the total station body 1 can be detached from the top of the base 2 by simply pulling the limit rod 606 out of the limit hole 608. The disassembly and assembly method of the mounting seat 7 and the total station body 1 and the base 2 is simple and easy to operate, which is convenient for quickly assembling and fixing the total station body 1 on the top surface of the base 2 for measurement operations, and is also convenient for When use is completed, the total station body 1 is removed from the top of the base 2 and stored for daily maintenance, which improves the flexibility of the measurement operation. In addition, during the entire measurement operation, since the control host 505 is integrated with the wireless and Bluetooth control module 504, the external handheld computer can realize remote wireless control of the general control component 5, the walking robot component 3, the total station body 1 and the correction sensor component 4 through the wireless and Bluetooth control module 504 and the control host 505. It is convenient to drive the base 2 to the set station measurement position by remotely controlling the walking robot component 3, and it is convenient to complete the measurement operation by remotely controlling the total station body 1 and the correction sensor component 4, which effectively improves the efficiency of the high-speed rail operation line precision control network measurement.

[0032] According to current statistics, there are more than 40,000 kilometers of high-speed rail lines in operation in my country. According to the requirements of the standard guidelines, each line needs to be re-surveyed every four years, that is, more than 10,000 kilometers of high-speed rail control network need to be re-surveyed every year. In view of the current situation that the high-speed rail operation window time does not exceed four hours, this plan is expected to effectively improve the re-survey efficiency by more than 30%, and at the same time, the number of technical personnel involved can be reduced by about 30%, which is expected to create greater social and economic value.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
