Description

Technical Field

[0001] The present invention relates to the technical field of rail information processing, and in particular to a rail length measuring method, a rail information management system and a storage medium. Background Art

[0002] After completing the rail welding, the rail welding base needs to measure the length of the rail and spray the length data on the rail to facilitate subsequent railway rail replacement operations.

[0003] Currently, rail welding bases mainly rely on manual methods to measure long rails. However, since a complete rail is welded from multiple short rails, the short rails need to be cut or repaired during the welding process, which will cause a large error between the overall length of the complete rail and the sum of the lengths of the multiple short rails. In addition, the rail is longer after welding, and the overall length of the rail can reach 500 meters. The accuracy of manual measurement alone is very low.

[0004] In addition, during the manual measurement process, it is necessary to mark the scale in advance, stop one end of the rail accurately at the origin of the scale, and record the scale scale that the other end of the rail is facing by manual measurement to obtain the length of the complete rail. However, the rails are usually started and stopped by a roller track. If a 500-meter-long, approximately 30-ton rail is to be accurately parked at the origin of the scale through a roller track, the control personnel need to make multiple adjustments to barely align the end of the rail with the origin of the scale, resulting in very low efficiency in the length measurement process.

[0047] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0048] Embodiment 1

[0049] This embodiment provides a rail length measurement method, which can replace the manual measurement method and detect the length of the rail to be measured through a sensing component, thereby improving the measurement accuracy and efficiency.

[0050] Specifically, Figure 1 As shown in FIG. 1 , the rail length measurement method specifically includes the following steps:

[0051] Step S1: Acquire multiple sensing signals, where the sensing signals are generated by two sensing components located at two ends of the rail to be measured, and there is a fixed distance between the two sensing components before measurement.

[0052] It should be noted that the sensing component is set on a preset track, and the sensing component can move axially back and forth along the preset track; and the rail to be tested can move along the roller line, wherein the preset track and the roller line are parallel to each other, so as to achieve the effect of axial movement of the sensing component at the left and right ends of the rail to be tested.

[0053] In this embodiment, two initial positions are pre-set on the preset track. Before the length measurement is performed, the two sensing components are respectively located at their corresponding initial positions. Since the distance between the two initial positions is known, before the length measurement is performed, that is, in the initial state, there is a fixed distance between the two sensing components, and the fixed distance is known.

[0054] It needs to be explained that the sensing component has a transmitting end and a receiving end. The transmitting end can emit a detection signal, such as laser, sound wave, etc.; the receiving end can receive the reflected detection signal; assuming that there is an obstruction in front of the sensing component, the detection signal emitted by the sensing component will be reflected by the obstruction, and the sensing component outputs a sensing signal when it receives the reflected detection signal.

[0055] Similarly, assuming there is no obstruction in front of the sensing component, the detection signal emitted by the sensing component cannot be returned, and the receiving end of the sensing component does not receive the reflected detection signal. The sensing component will also output a sensing signal, but the sensing signal is different from the sensing signal output when there is an obstruction.

[0056] In this embodiment, the transmitting end and the receiving end of the sensing component are integrated on the same side, or a laser sensor is directly used to achieve the effects of transmitting and receiving.

[0057] Step S2: Identify the signal type of each sensing signal, determine the moving direction of the two sensing components according to the signal type of each sensing signal, and control each sensing component to move along its corresponding moving direction during measurement.

[0058] Specifically, when the sensing signal is the first signal, it is determined that the sensing component corresponding to the first signal is the first sensing component 1; the first signal is generated when the sensing component detects the presence of an obstruction;

[0059] When the sensing signal is the second signal, it is determined that the sensing component corresponding to the second signal is the second sensing component 2; the second signal is generated when the sensing component detects that there is no obstruction.

[0060] This embodiment can measure the length of the steel rails of different lengths. When the steel rail of unknown length moves along the roller track to the area where the two sensing components are located, the following situations may occur:

[0061] 1. Both sensing components are not blocked by the rail to be tested (e.g. Figure 2 Scenario shown);

[0062] 2. One of the sensing components is blocked by the rail to be tested, while the other sensing component is not blocked by the rail to be tested (e.g. Figure 3 Scenario shown);

[0063] 3. The two sensing components are blocked by the rail to be tested (such as Figure 4 scene shown).

[0064] In this embodiment, the direction of controlling the movement of the sensing component may be different in different situations, specifically:

[0065] When the sensing signal is a first signal, a first control instruction is generated according to the first signal and sent to the first sensing component 1 to control the first sensing component 1 to move axially along a first direction, where the first direction is a direction away from the midpoint of the rail to be measured;

[0066] When the sensing signal is the second signal, a second control instruction is generated according to the second signal and sent to the second sensing component 2, and the second sensing component 2 is controlled to move axially along the second direction according to the second signal, and the second direction is the direction close to the midpoint position of the rail to be measured.

[0067] Combined with Figure 3 Description, in Figure 3 The first direction is Figure 3 The direction indicated by the arrow on the right side of the middle, the second direction is Figure 3In the direction indicated by the arrow on the left.

[0068] Step S3: Obtain a preset moving speed, and record the moving time of each sensing component when the signal changes during the moving process, and calculate the length of the rail to be measured according to each moving time, moving speed and fixed distance.

[0069] It should be noted that the moving speed can be set in advance so that each sensing component moves at a uniform speed according to the preset moving speed.

[0070] In this embodiment, when any sensing component starts to move, the timing operation is started, and the changes in the sensing signal output by the sensing component during the movement are monitored in real time; when the sensing component moves to a certain position, the sensing signal output by the sensing component changes, from outputting the first signal to outputting the second signal, or from outputting the second signal to outputting the first signal, which means that the sensing component moves to the position directly opposite to the end of the rail to be tested. At this time, the moving time of the sensing component is counted according to the timing time, and the moving time can be combined with the preset moving speed to calculate the moving distance of the sensing component.

[0071] With the cooperation of the two sensing components, the moving distance of the first sensing component 1 is calculated according to the moving time of the first sensing component 1 and the preset moving speed to obtain the first moving distance;

[0072] Calculate the moving distance of the second sensing component 2 according to the moving time and moving speed of the second sensing component 2 to obtain a second moving distance;

[0073] The length of the rail to be measured is calculated according to the first moving distance, the second moving distance and the fixed distance.

[0074] It should be noted that when calculating the length of the steel rail to be measured, it is necessary to determine whether the value of the moving distance is a positive value or a negative value according to the moving direction of the sensing component. In this embodiment, assuming that the first direction is a positive direction, the moving distance of the sensing component moving along the first direction is a positive value; assuming that the second direction is a negative direction, the moving distance of the sensing component moving along the second direction is a negative value, so as to accurately calculate the length of the steel rail to be measured.

[0075] For example, combining Figure 2 , Figure 5As shown, when it is recognized that both sensing signals are the second signal, it means that both sensing components are in an unblocked state, and at this time, both sensing components are called second sensing components 2; the two second sensing components 2 are controlled to move axially along the second direction, that is, gradually move toward the direction close to the midpoint position of the rail to be measured, which is equivalent to the two second sensing components 2 moving toward each other, and the moving time when the sensing signals of the two second sensing components 2 change is recorded respectively, and the corresponding moving distances are calculated according to their respective moving time (the moving distances of the two second sensing components are shown in FIG. Figure 5 Since both second sensing components 2 move along the second direction, the moving distances of the two second sensing components 2 are both negative values. At this time, the fixed distance ( Figure 5 The length of the rail to be measured is obtained by subtracting the moving distances (S1 and S2) of the two second sensing components 2 from S0 in the figure.

[0076] Furthermore, in order to improve the reliability of the measurement result, a sensing component can be composed of two first laser sensors, such as Figure 5 As shown, Figure 5 The meaning of the double vertical lines in the middle is a schematic diagram of two first laser sensors emitting lasers for detection at the same time; the two first laser sensors move synchronously and detect simultaneously, and there is a fixed distance between the two first laser sensors. In this embodiment, the fixed distance is relatively small. In each measurement, the measurement results of the two first laser sensors can be checked against each other. If the time points at which the signals of the two first laser sensors change during the movement differ greatly, an alarm can be issued; if the time points at which the signals of the two first laser sensors change during the movement coincide with the fixed distance between the two first laser sensors, it means that the measurement is normal.

[0077] Under normal measurement conditions, the two first laser sensors in the same sensing component are detected simultaneously, and the movement time of the two first laser sensors in the same sensing component is recorded. The average value of the two movement time is calculated, and the value calculated based on the average value and the moving speed is used as the moving distance of the sensing component to improve the accuracy and reliability of the measurement results.

[0078] On the other hand, the two first laser sensors of the same sensing component detect and move synchronously at the same time, so that when one of the laser sensors fails, the measurement task can still be continued through the other laser sensor, thereby improving the measurement efficiency.

[0079] Furthermore, at least two second laser sensors may be arranged between the two sensing components, such as Figure 5 As shown, Figure 5The middle longitudinal single line represents the laser emitted by the second laser sensor; the second laser sensor is fixed on a preset track, that is, the second laser sensor cannot move, and two second laser sensors are fixed on the track, and the distance between them is also known.

[0080] It should be noted that the detection principle of the second laser sensor in this embodiment is the same as the detection principle of the sensing component, and will not be described again here.

[0081] Before acquiring the sensing signal of the sensing component, firstly acquiring the detection signals of two second laser sensors, where the two second laser sensors are both located between the two sensing components;

[0082] When the detection signals of the two second laser sensors are both the first signals, that is, the lasers emitted by the two second laser sensors are reflected and received by the rail to be measured, it means that the rail to be measured has now reached the measurement area between the two sensing components. At this time, the two sensing components can be activated to start measuring, thereby obtaining the sensing signals output by the two sensing components, and determining the moving direction of the sensing components based on the sensing signals, so as to locate the position of the rail to be measured.

[0083] In this embodiment, the distance between the two second laser sensors can be set to be approximately equal to the length of the rail to be measured, so as to reduce the distance from the sensing component to the end of the rail to be measured, so as to quickly complete the task of accurately measuring the length of the rail to be measured.

[0084] It should be noted that, after completing the length measurement task of the current rail to be measured, this embodiment controls the two sensing components to reset. At this time, the two sensing components are restored to their corresponding initial positions to facilitate the subsequent execution of other measurement tasks.

[0085] This embodiment is provided with two sensing components, and the sensing signals of the two sensing components are used to determine whether the laser emitted by each sensing component is blocked by the rail to be measured, and the moving directions of the two sensing components are determined respectively according to the blocked state of each sensing component, and timing is performed during the movement of each sensing component, and the moving time of each sensing component when the signal changes during the movement is recorded, and the length of the rail to be measured is calculated according to each moving time, a preset moving speed, and a fixed distance between the two sensing components. The present invention measures the length of the rail through multiple sensing components, replacing the manual measurement method, and can improve the measurement accuracy and efficiency.

[0086] Embodiment 2

[0087] This embodiment provides a rail information management system, combined with Figure 6 , Figure 7 As shown, the system includes the following modules:

[0088] The rail measuring module is used to execute the rail length measuring method as in the first embodiment; the functions of this module can refer to the corresponding description in the above method, which will not be repeated here.

[0089] The spray control module is connected to the rail measuring module and is used to receive the length information of the rail to be measured output by the rail measuring module and perform a spray operation, wherein the spray operation is to spray the length information to a designated position of the rail to be measured.

[0090] It should be noted that the inkjet control module of this embodiment uses an automatic inkjet printer to implement inkjet operation. The inkjet control module receives the length information of the rail to be measured output by the rail measurement module in real time through the WIFI / Bluetooth interface, and generates corresponding inkjet instructions according to the length information, the model of the rail to be measured, etc. After receiving the inkjet instruction, the automatic inkjet printer sprays the length information, the model of the rail to be measured, etc. at the designated position of the rail to be measured. In addition, the inkjet control module can automatically switch the inkjet content according to the information of different rails to be measured, thereby improving work efficiency.

[0091] Furthermore, the rail information management system also includes:

[0092] The scanning module is used to scan and obtain the barcode information of the rail to be tested; wherein, the scanning module is composed of a barcode scanner, which is connected to the rail measuring module in real time. When the second laser sensor of the rail measuring module detects that the rail enters the measuring range, the barcode scanner can be moved on a preset track to scan all the barcodes on the rail to be tested in real time. For example, the scanning module scans the rail code at a speed of 85 frames per second; in addition, the barcode scanner can also be fixed, and the rail to be tested passes through the barcode scanner when moving along the roller line, thereby scanning all the barcodes on the rail to be tested.

[0093] If the barcode scanner scans a valid code, it will compare the scan result with the previously obtained result to determine the information of the current rail to be tested; if there is no such result before, it will be stored and managed; when the laser sensor cannot sense the rail, the scanning module stops scanning.

[0094] Furthermore, the rail information management system also includes:

[0095] The ledger management module is connected to the scanning module, the rail measurement module and the inkjet control module. The ledger management module is used to record and store various information of each rail, such as barcode information, length information, rail type, working edge, etc., and associate the barcode information, length information, rail type, working edge, etc. to collect all the information of each rail; the ledger management module also provides database storage, query, export and other functions.

[0096] Furthermore, the rail information management system also includes:

[0097] The visual interaction module is connected to the ledger management module. The visual interaction module uses intuitive graphics to express the status of each part of the system, guide customers to operate correctly, and display the results of measurement, printing, etc., which is convenient for users to use. Through the visual graphics interface, users can monitor the working status of the rail measurement module, the current process, the rail code obtained by the scanning module, and the rail position in real time. The rail length measurement function can be realized through the software button, and the measurement results of the rail length can be displayed in real time.

[0098] Furthermore, the rail information management system also includes:

[0099] The rail type management module is connected to the visual interaction module and the printing control module, and is used to receive the specified rail type information input by the user through the visual interaction module, and select the corresponding identification of the specified rail type from the database according to the specified rail type information and send it to the printing control module, so that the printing control module can print the specified rail type information onto the rail according to the identification.

[0100] Furthermore, the rail information management system also includes:

[0101] The abnormal alarm module alarms the abnormalities of the entire system, including abnormal collected barcode data, abnormal measured length information, abnormal equipment operation, etc., and provides real-time alarms.

[0102] The steel information management system of this embodiment integrates multiple technologies such as laser sensing measurement, scanning collection and identification, and information platform, and comprehensively realizes functions such as automatic measurement of rail length, automatic scanning and registration of rail codes, automatic sending of rail spraying information to switching spraying, automatic record of information and automatic upload to the rail information system, thereby improving the degree of automation of information management. After the steel information management system is deployed, the entire measurement process has a high degree of automation, and a single person can achieve high-precision measurement of rail length. In addition, during operation, the system does not touch the rails or invade the roller track, so it can ensure production safety to the greatest extent.
