Description

Technical Field

[0001] The present invention relates to the field of equipment installation calibration and data verification, and in particular to a device and method for track equipment installation calibration and data verification. Background Art

[0002] As the cornerstone of the signaling system, the calibration, installation, and position verification of track equipment—such as signal machines, axle counters, beacons, and switches—are paramount in the early stages of urban rail signaling projects. The efficiency of equipment installation, calibration, and data verification is a major factor impacting project progress. As the foundation for subsequent line-wide data generation from the signaling system, accuracy is also crucial to project quality.

[0003] In traditional signal projects, the installation and calibration of equipment usually uses a manual tape measure. Due to the softness of the tape and the complex on-site factors, this calibration method has a large error. The error in one section usually exceeds several meters, which easily leads to rework. The installation and verification of track equipment are usually performed manually using a laser rangefinder to measure the distance of each device one by one. Due to the influence of daylight, it can only be carried out at night or in tunnels. For example, Chinese patent CN219417741U discloses a subway signal trackside equipment laser measurement device, which includes two subway signal trackside equipment laser measurement device bodies arranged in parallel; wherein the subway signal trackside equipment laser measurement device body includes a measuring square, a reflective plate, a laser rangefinder and a laser rangefinder fixing platform; the side rod is clamped on the outer edge of one side of the rail to make the horizontal rod perpendicular to the rail, eliminating the step of adjusting the horizontal rod. After completing the laser distance measurement, the data needs to be reviewed and verified by the train, which is time-consuming and inefficient. Summary of the Invention

[0045] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0046] Example 1

[0047] This embodiment provides a track equipment installation measurement and data verification device, such as Figure 1 As shown, it includes: a core control module 1, a track data processing module 2, a PLC drive and acquisition module 3, a high-speed IO acquisition board 4, a signal conversion board 5, an odometer 6, a motor 7 and a laser alignment trigger module 8.

[0048] The core control module 1 is used to control the PLC drive and acquisition module 3 to cause the track equipment measurement and data verification device to generate displacement.

[0049] The track data processing module 2 is used to receive the odometer signal transmitted by the high-speed IO acquisition board 4, obtain the displacement information of the track equipment measurement and data verification device, and perform installation measurement and data verification.

[0050] The PLC driving and acquisition module 3 is used to drive the motor 7 and acquire the trigger signal transmitted by the laser alignment trigger module 8.

[0051] The high-speed IO acquisition board 4 is used to collect the high and low level signals output by the odometer 6 and output them to the track data processing module 2.

[0052] The signal conversion board 5 is used to connect the high-speed IO acquisition board 4 and the odometer 6, convert the sensor signal in the odometer 6 into a single-ended signal of appropriate voltage, and input it into the high-speed IO acquisition board 4.

[0053] The odometer 6 is used to collect displacement signals of the track equipment measurement and data verification device.

[0054] The motor 7 is used to drive the track equipment measurement and data verification device to move at a preset speed.

[0055] The laser alignment trigger module 8 is used to generate a trigger signal when the laser scans the trackside equipment at a height different from the track plane.

[0056] The core control module 1 includes a software user interface. Its first function is to serve as the front-end display for the track data processing module 2, displaying track data processed by the module on the software user interface. Displacement information is output as a track equipment data measurement table and a track equipment installation verification table. Track data includes various information, including speed, cumulative number of running gears, and displacement direction.

[0057] Function 2 is the host computer for the PLC drive and acquisition module 3. The track equipment installation, measurement, and data verification device can be moved in two modes: automatic and manual control. When automatic control is selected, the core control module 1 drives the motor 7 through the PLC drive and acquisition module 3 to move the track equipment installation, measurement, and data verification device.

[0058] The track data processing module 2 is a module for calculating the displacement information of the track equipment installation, measurement and data verification device. It receives the odometer signal transmitted by the high-speed IO acquisition board 4. The odometer signal includes high and low level signals from three photosensitive sensors. The track data processing module 2 converts the high and low level signals into the cumulative number of running teeth according to one cycle as one tooth, and calculates the tooth pitch according to the preset wheel diameter. The displacement of the track equipment installation, measurement and data verification device is obtained according to the cumulative number of running teeth and the tooth pitch.

[0059] Track data processing module 2 obtains speed information based on the frequency and tooth pitch of high and low level signals. The calculation formula is:

[0060] V=f*n*10-3*3.6

[0061] Where f is the signal frequency, n is the tooth pitch, and V is the speed.

[0062] The track data processing module 2 obtains the displacement direction of the track equipment installation measurement and data verification device through the phase difference of the three photosensors.

[0063] The PLC drive and acquisition module 3 is used to drive the motor 7 to displace the track equipment installation, measurement, and data verification device, and to collect trigger signals transmitted by the laser alignment trigger module 8. The PLC drive and acquisition module 3 includes a PLC drive unit and an acquisition unit. The PLC drive unit outputs an analog signal to drive the motor 7 at the rated speed, while the acquisition unit collects trigger signals transmitted by the laser trigger signal. The PLC drive and acquisition module 3 is controlled by the host computer in the core control module 1.

[0064] The high-speed I / O acquisition board 4 is the primary board for collecting odometer signals. It collects the high and low-level signals output by the odometer 6 and outputs them to the track data processing module 2. This board features a 32-channel high-speed digital I / O module that supports signal levels from 1.8 to 5V. It utilizes the PCIE bus and offers high-performance acquisition capabilities. By programming the data direction and sequence, it can seamlessly collect the high and low-level signals output by the odometer 6 and output them to the track data processing module 2.

[0065] The signal conversion board 5 connects the high-speed IO acquisition board 4 and the odometer 6, converting the sensor signals in the odometer 6 into single-ended signals of appropriate voltages for input into the high-speed IO acquisition board 4. The sensor signals in the odometer 6 are differential signals and require signal conversion to convert them into single-ended signals of appropriate voltages for input into the high-speed IO acquisition board 4. The signal conversion board 5 also filters out noise and isolates the odometer power supply.

[0066] Odometer 6 is the core module of the track equipment installation, measurement, and data verification device, collecting displacement signals. Odometer 6 comprises three photosensors and a code disk. When the track equipment installation, measurement, and data verification device moves, the wheels of the device drive the code disk via the speed drive shaft. Light beams pass through the code disk's gears and illuminate the three photosensors, generating high and low level signals in sequence. A cycle of high and low level signals is called a tooth count. The three photosensors are positioned at 120 degrees in a triangular pattern, ensuring that the phase difference between them allows for direction determination.

[0067] Motor 7 is the motor device that enables automatic vehicle control for the track equipment installation, measurement, and data verification device. Motor 7 drives the wheel drive shaft via a belt, driving the track equipment installation, measurement, and data verification device at a preset speed. The analog signal output by the PLC drive unit controls the preset speed. To ensure accurate speed control, a brushless motor is used to achieve a more precise rated speed output. The PLC drive and acquisition module 3 synchronizes speed information with the track data processing module 2 to adjust the operating speed of motor 7.

[0068] Laser alignment trigger module 8 assists the track equipment installation, measurement, and data verification device in achieving alignment. Positioned at the center opening of the device, the laser beam shines directly at the track plane at a 90-degree angle. When the laser passes over trackside equipment at a different height than the track plane, a trigger signal is transmitted to PLC drive and acquisition module 3, causing the system to stop. Laser alignment trigger module 8 can also assist with installation verification by manually aligning the center point of installed equipment.

[0069] Example 2

[0070] This embodiment provides a method for track equipment installation, measurement and data verification, such as Figure 3 As shown, the following steps are included:

[0071] After confirming that all wires are correctly connected, power on the control terminal and start the software control. Wait for the software control module and hardware module to pass the initialization self-test to complete the initialization of the generator. Align the laser alignment trigger module 8 with the starting measurement position and reset the mileage information in the odometer 6.

[0072] Select between automatic and manual control modes within the software. Automatic control uses the motor of the remote control device within the software to move the vehicle, while manual control uses the bypass motor to manually move the vehicle. Selecting automatic control allows you to set a travel distance or maintain a constant speed. Manual control allows the user to manually control the vehicle to start moving.

[0073] The motor 7 is driven by the PLC drive and acquisition module 3 to cause the track equipment installation, measurement and data verification device to move.

[0074] Perform installation measurement by running the preset distance through automatic vehicle control. After reaching the preset distance, mark the center point of the equipment installation according to the position irradiated by the laser of the laser alignment trigger module 8, and record the displacement information and equipment name of the equipment at that position, and continue with the installation measurement of the next equipment; if the measurement is not continued, output the equipment installation measurement form.

[0075] Perform equipment calibration, align the laser of the laser alignment trigger module 8 with the center position of the installed equipment through the automatic vehicle control, record the current equipment name and the corresponding displacement information and equipment name, and continue to calibrate the installation data of the next equipment; if the calibration is not continued, output the equipment installation calibration form.

[0076] The rest is the same as in Example 1.

[0077] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
