[0044] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0045] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0046] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0047] Railway signal equipment limits mainly refer to the spatial dimension restrictions on railway signal equipment and their installation locations on railway lines to ensure the safe operation of railway signal equipment and the safe operation of trains. Specifically, railway signal equipment limits refer to the contour lines that various railway signal equipment on the line must not invade. They are safety reserves based on vehicle limits, including vehicle offset and tilt caused by the maximum allowable error of the track, as well as factors that are difficult to predict during design, construction, and operation. Railway signal equipment limits are a control line that is used to restrict railway signal equipment from invading this line, thereby ensuring the safety of mobile equipment such as trains during operation. This restriction is intended to prevent railway signal equipment from colliding or interfering with trains, other railway equipment, or buildings.

[0048] In order to ensure that railway signal equipment does not intrude into the railway construction clearance range and maintain a safe distance from the train, it is necessary to measure the railway signal equipment clearance during the railway signal equipment maintenance and project acceptance process.

[0049] The existing conventional measurement method requires the cooperation of multiple staff members, which has a complicated process and a large workload.

[0050] Specifically, the traditional limit measurement method of railway signal equipment is mainly based on on-site measurement using traditional measuring tools, such as vernier calipers, tape measures, etc. The surveyor needs to go to the site in person and use tools such as vernier calipers and tape measures to measure each key part of the railway signal equipment one by one, record the data and process it to obtain the measured limit value.

[0051] The traditional method of measuring the clearance of railway signal equipment has many problems:

[0052] Question 1: Measurement accuracy is greatly affected by human factors: During manual measurement, the skill level and operating habits of the measurement personnel may affect the accuracy of the measurement results. Once the staff does not master the measurement method, the measurement data will be inaccurate. Even if the staff operates the measurement method correctly, the accuracy of the measurement data is still affected by the human perspective.

[0053] Question 2: Measurement accuracy is affected by measuring tools: The measuring tools used in the measurement process will also affect the measurement results. For example, if a tape measure is used for measurement, it is easy to cause inaccurate measurement data, and if a steel ruler is used for measurement, it is easy to cause a short circuit in the track circuit.

[0054] Problem 3: Low measurement efficiency: The traditional limit measurement method of railway signal equipment requires surveyors to measure each point one by one, which is labor-intensive and time-consuming.

[0055] Question 4: High safety risk: Surveyors need to work on the railway site, which may expose them to safety risks such as being hit by trains.

[0056] Problem 5: Complicated data processing: The traditional method of measuring the clearance of railway signal equipment requires manual recording and processing of large amounts of data, which is labor-intensive and prone to errors.

[0057] Question 6: Susceptible to environmental influences: Environmental factors such as weather and light may affect the accuracy and stability of traditional measurement tools.

[0058] It can be seen that, although the traditional railway signal equipment clearance measurement method has certain application value, it has obvious deficiencies in measurement accuracy, efficiency, safety and data processing. Therefore, in order to solve the above problems, this application proposes a railway signal equipment clearance measurement device, system and method, which improves and optimizes the above traditional measurement method and can better meet the needs of railway transportation safety and efficient operation.

[0059] Optional, see Figure 1 , a schematic structural diagram of a railway signal equipment limit measurement device provided in this application.

[0060] like Figure 1 As shown, the railway signal equipment clearance measuring device can also be called a measuring instrument. The device is installed on the track near the railway signal equipment, and includes a main control module, a horizontal distance sensor, a vertical distance sensor, a horizontal angle sensor and a power module. The main control module is connected to the horizontal distance sensor, the vertical distance sensor and the horizontal angle sensor respectively, and the power module is connected to each of the above-mentioned modules respectively.

[0061] The distance measuring sensors in this application include horizontal distance measuring sensors and vertical distance sensors. The distance measuring sensor is a sensor that can measure the distance between objects. It uses different physical principles and technical means to achieve accurate distance measurement. It is widely used in industrial automation, robot navigation, drone positioning, vehicle safety systems, intelligent manufacturing and other fields. This application does not limit the type of distance measuring sensors, including but not limited to laser distance measuring sensors, ultrasonic distance measuring sensors, infrared distance measuring sensors and millimeter wave radar sensors, etc. Surveyors can choose the most suitable type of distance measuring sensor according to specific needs and environmental conditions.

[0062] Among them, the horizontal distance sensor is used to measure the horizontal distance between the railway signal equipment and the railway signal equipment clearance measurement device, specifically to measure the horizontal distance between the inner side of the rail head and the railway signal equipment, with millimeter-level accuracy. Its measurement data will be transmitted to the main control module and exchange data with the main control chip in the main control module. For example, see Figure 2 , a schematic diagram of the inner side of the rail head and the horizontal distance provided in this application.

[0063] The vertical distance measuring sensor is used to measure the vertical distance between the railway signal and the upper surface of the rail. It is specifically used to measure the vertical distance between the railway signal equipment and the rail surface with millimeter-level accuracy. The measurement data will be transmitted to the main control module and exchange data with the main control chip in the main control module.

[0064] A horizontal angle sensor, also known as an inclination sensor or a level, is a sensor used to measure the inclination angle of an object or system relative to a horizontal plane. It mainly detects changes in static gravity acceleration and converts the changes in static gravity acceleration into information about inclination changes, thereby achieving accurate measurement of the horizontal angle. Horizontal angle sensors are widely used in many fields such as engineering vehicle leveling, high-altitude platform safety protection, and directional satellite communication antenna pitch angle measurement. In this application, the horizontal angle sensor is mainly used to measure the horizontal angle of the railway signal equipment limit measurement device relative to the reference plane, and the reference plane can be understood as a horizontal plane. Specifically, the horizontal angle data of the railway signal equipment limit measurement device measured by it relative to the reference plane will be transmitted to the main control module, and the main control module will determine whether the railway signal equipment limit measurement device is in a horizontal state based on the received horizontal angle data. It can be understood that the horizontal angle sensor is used to calibrate the horizontal state of the railway signal equipment limit measurement device.

[0065] The main control module includes a main control chip and related circuits, which can control the above-mentioned modules such as the horizontal distance sensor, vertical distance sensor and horizontal angle sensor through a single-chip microcomputer.

[0066] Specifically, the main control chip in the main control module receives the horizontal angle data of the railway signal equipment limit measuring device relative to the reference plane collected by the horizontal angle sensor, and determines whether the measuring device is in a horizontal state through the horizontal angle data. When it is determined that the horizontal angle data indicates that the measuring device is not in a horizontal state, an alarm message is issued.

[0067] It should be noted that the measuring device provided in the present application may also include a display screen. When the main control chip determines that the horizontal angle data relative to the horizontal plane collected from the horizontal angle sensor indicates that the measuring device is not in a horizontal state, the display screen can directly give a prompt, and the measuring device can also emit an alarm sound effect for prompting.

[0068] In addition, the main control chip in the main control module also receives the horizontal distance between the railway signal equipment and the railway signal equipment limit measurement device collected by the horizontal distance measurement sensor, and the vertical distance between the railway signal and the upper surface of the rail collected by the vertical distance measurement sensor. Then, the measured distance is determined based on the horizontal distance and the vertical distance, and it is judged whether the measured distance exceeds the preset limit. When the measured distance exceeds the preset limit, an alarm message is issued.

[0069] Specifically, when the railway signal equipment clearance measuring device is in a horizontal state for measurement, the horizontal distance measuring sensor measures the distance, and the horizontal distance collected by the horizontal distance measuring sensor is compared with the preset clearance for judgment.

[0070] When the railway signal equipment limit measurement device is not in a horizontal state for measurement, the horizontal distance and the vertical distance are input into a preset logical operation formula to calculate the corrected horizontal distance, and the corrected horizontal distance is used as the measured distance for comparison and judgment with the preset standard limit.

[0071] It should be noted that after the railway signal equipment clearance measuring device is installed, the horizontal angle sensor will first detect whether the measuring device is installed horizontally. If it is not installed horizontally, the measuring device will issue an alarm message to prompt the measurement personnel to reinstall it. However, if the railway signal equipment clearance measuring device cannot be installed horizontally on site, the main control chip in the main control module can correct the horizontal distance collected by the horizontal distance measuring sensor and the vertical distance collected by the vertical distance measuring sensor through a preset logical operation formula.

[0072] The power module mainly includes a lithium battery and a charging and discharging circuit. The module can output 3.3V / 5V and other voltages to charge various sensors, main control chips and other modules. The module also includes protection circuits such as overvoltage protection. Among them, the charging and discharging circuit can charge the lithium battery and also power various sensors and modules. The lithium battery is used to provide power for the entire railway signal equipment limit measurement device.

[0073] Optional, see Figure 3 , another structural schematic diagram of the railway signal equipment limit measurement device provided in this application.

[0074] The above-mentioned railway signal equipment clearance measuring device also includes a device housing, on which a horizontal distance measuring sensor and a vertical distance measuring sensor are embedded, and also includes a charging interface.

[0075] Specifically, the horizontal distance measuring sensor is embedded in the side wall of the device housing. When installing the railway signal equipment clearance measuring device, the side wall embedded with the horizontal distance measuring sensor is aligned with the inner side of the rail head, so that the horizontal distance measuring sensor can measure the horizontal distance between the inner side of the rail head and the railway signal equipment.

[0076] The vertical distance measuring sensor is embedded in the bottom surface of the device housing. Before the measuring device starts measuring, the measuring device will be adjusted to the same height as the railway signal equipment. At this time, the vertical distance measured by the vertical distance measuring sensor can be used to characterize the distance of the railway signal equipment relative to the reference plane (horizontal plane).

[0077] For example, see Figure 4 , a structural example diagram of a railway signal equipment limit measurement device provided in this application.

[0078] like Figure 4 As shown, the distance sensor 1 is a horizontal distance sensor and the distance sensor 2 is a vertical distance sensor. The distance sensor 1 is embedded in the side wall of the device housing, and the charging interface is on the side wall opposite to the side wall where the distance sensor 1 is embedded. The distance sensor 2 is embedded in the bottom surface of the device housing.

[0079] Optionally, the railway signal equipment limit measurement device provided by the present application also includes a communication module, and the communication module is connected to the main control module and the power module respectively. The communication module mainly includes a communication chip and related circuits, and the communication chip is used to receive data communication instructions issued by the main control chip, communicate data with the terminal according to the communication protocol, and transmit or receive data to the terminal. It should be noted that the measuring device performs periodic data communication with the terminal through the communication module, and the data content of the data communication specifically includes the measurement data collected by each sensor and the measurement distance determined by the main control chip; the terminal can specifically be a handheld terminal or a cloud.

[0080] Optionally, the communication module provides communication modes including wireless communication and wired communication. Specifically, the railway signal equipment clearance measurement device transmits the measurement data and measurement results to the handheld terminal or the cloud through the communication module. In addition, other Android or Windows terminal devices such as mobile phones, tablet computers, and micro industrial computers can export measurement data in excel and txt formats through the USB interface of the measuring device, or upload the measurement data and measurement results to the cloud through the USB interface.

[0081] Specifically, the human-computer interaction software of each of the above terminals can compare the measured data with the standard data. When it is determined that the railway signal equipment is out of limit, the terminal equipment will issue an alarm message.

[0082] Optionally, the railway signal equipment clearance measurement device provided by the present application also includes a storage module, which mainly includes a memory card. The specific storage module is connected to the main control module and is used to store measurement data. When there is no handheld terminal or it is impossible to upload to the cloud, the memory card can store sufficient measurement data.

[0083] For example, see Figure 5 , an example diagram of the structural composition of the railway signal equipment limit measurement device provided in this application.

[0084] like Figure 5 As shown, the measuring instrument, i.e., the railway signal equipment limit measuring device, includes a main control chip and related circuits, a distance sensor 1, a distance sensor 2, a horizontal angle sensor, a memory card, a wireless communication circuit, a charging and discharging circuit, and a lithium battery.

[0085] Among them, the main control chip and related circuits are respectively connected to the distance sensor 1, the distance sensor 2, the horizontal angle sensor, the memory card, the wireless communication circuit, and the charging and discharging circuit. The main control chip is connected to each sensor mainly to obtain measurement data from each sensor, namely, the horizontal distance, the vertical distance, and the horizontal angle data of the measuring instrument relative to the horizontal plane. The memory card is used to store the measurement data obtained by the main control chip from each sensor.

[0086] The main control chip can control the wireless communication circuit to communicate data with terminal devices or cloud storage through Bluetooth, WIFI and 4G / 5G mobile networks.

[0087] It will be appreciated that the charge and discharge circuit provides power to various components in the measuring instrument.

[0088] The measuring instrument provided in this application does not require manual recording, proofreading and other links, and can achieve low manual participation and large amounts of data management; it has no technical qualification requirements for measurement personnel, has a high degree of intelligence, and can realize real-time analysis and uploading of measurement data, over-limit alarm lights and other functions.

[0089] In summary, the railway signal equipment limit measuring device provided by the present application includes a main control module and a horizontal distance measuring sensor, a vertical distance measuring sensor, and a horizontal angle sensor respectively connected to the main control module; wherein the main control module is used to obtain the horizontal distance collected by the horizontal distance measuring sensor, the vertical distance collected by the vertical distance measuring sensor, and the horizontal angle collected by the horizontal angle sensor; judge whether the measuring device is in a horizontal state according to the horizontal angle, and if it is not in a horizontal state, issue an alarm message; measure the distance by the horizontal distance and the vertical distance, and judge whether the measured distance exceeds the preset limit, and issue an alarm message when the measured distance exceeds the preset limit. In addition to the above-mentioned measuring device, the measuring system also includes a bracket structure and a handheld terminal. The present application only needs to install the railway signal equipment limit measuring device on the rails to automatically start the limit measurement of the railway signal equipment, without the participation of multiple staff members, with a simple process, small workload, and high testing efficiency.

[0090] A railway signal equipment clearance measuring device provided in an embodiment of the present application is introduced above, and a railway signal equipment clearance measuring system including the railway signal equipment clearance measuring device will be introduced below.

[0091] The measurement system provided in the present application includes not only the railway signal equipment clearance measurement device introduced above, but also a bracket structure and a handheld terminal.

[0092] It can be understood that the support structure is used to set up the measuring device, and the measuring device is set up above the rail.

[0093] The support structure includes a support body, a fixed support of the railway signal equipment clearance measuring device, and a slide rod. The support body is clamped on the rail head through the bottom clamping claw, and the support body can be locked by a butterfly lock screw; the support body can be a telescopic tubular design of aluminum alloy. For example, see Figure 6 , a schematic diagram of the bracket structure installation provided in this application.

[0094] It should be noted that the support structure provided in this application is applicable to different types of rails.

[0095] The measuring device is mounted on a fixed bracket, which is fixed on a slide bar. The fixed bracket can adjust the horizontal angle of the measuring device relative to the horizontal plane, and the height of the measuring device can be adjusted by sliding the slide bar up and down. Specifically, before the measuring device starts to measure the horizontal distance and the vertical distance, the measuring device is adjusted to the same vertical height as the railway signal equipment through the slide bar, so as to ensure that the vertical distance collected by the vertical distance measuring sensor in the measuring device represents the distance between the railway signal equipment limit measuring device and the upper surface of the rail. It can be understood that the measuring system provided by the present application can be used to measure railway signal equipment of various heights.

[0096] A handheld terminal is a portable data processing terminal that usually has an operating system (such as Android, Windows Mobile, Windows CE, etc.), memory, CPU, graphics card and other hardware configurations, as well as input and output devices such as screen and keyboard. The handheld terminal has data storage and computing capabilities, can be developed secondary, can communicate data with other devices, has battery power supply, and supports wireless communication technologies (such as Bluetooth, Wi-Fi, 4G, etc.).

[0097] The handheld terminal is installed with railway signal equipment limit measurement software. This measurement software is self-developed software with human-computer interaction function. Its human-computer interaction interface can display the current date and time; display the name, equipment number and other information of the railway signal equipment; display the measurement data of various sensors in the measuring device and the measurement results (whether it exceeds the limit); also display option buttons for saving, clearing and uploading measurement data; display the power of the measuring device, measurement accuracy, communication parameters and other contents.

[0098] The handheld terminal can communicate data with the communication module in the measuring device, obtain the measurement data and make judgments, and realize the export, storage and clearing functions of the measurement data through software; it can also realize data transmission to the cloud.

[0099] For example, see Figure 7 , an example diagram of the interface of the railway signal equipment clearance measurement software provided in this application.

[0100] like Figure 7 As shown in the figure, the software interface shows that the power of the measuring device is 76%, the measurement time is 15:30 on December 7, 2023, the device name is signal machine, the device number is S1, the horizontal angle is 1 degree, the height is 50mm, the standard limit distance is 300mm, and the status of the measured railway signal equipment is within the limit. The software interface also includes data saving, data clearing and setting buttons.

[0101] It should be noted that the handheld terminal may be installed on the support structure or not.

[0102] When the handheld terminal is a small mobile phone type device, and the communication method between the handheld terminal and the railway signal equipment clearance measuring device is Bluetooth communication, it is preferred to install the handheld terminal on the bracket structure. When the Bluetooth communication method between the handheld terminal and the railway signal equipment clearance measuring device fails, the handheld terminal and the measuring device can be directly connected through a data cable to quickly restore normal communication.

[0103] When the communication mode between the handheld terminal and the railway signal equipment clearance measuring device is a wireless communication mode such as WiFi, the handheld terminal may not be installed on the bracket structure.

[0104] For example, see Figure 8 , an example diagram of the structural composition of the railway signal equipment clearance measurement system provided in this application.

[0105] like Figure 8 As shown, the measuring instrument, i.e., the railway signal equipment limit measuring device, is installed on a measuring instrument fixing bracket, the measuring instrument fixing bracket is fixed on a platform connected to the slide bar, and the handheld terminal is also fixed on the platform connected to the slide bar. The measuring instrument and the handheld terminal can adjust the vertical height by sliding the slide bar up and down.

[0106] The railway signal equipment limit measurement system provided by this application includes a measuring instrument equipped with a main control chip, a bracket structure and a handheld terminal equipped with self-developed software. It is a highly mature and highly intelligent limit measurement solution. It does not require manual comparison of measurement data, and can directly give the result of whether the railway signal equipment is over the limit. The degree of manual participation is very low, and the measurement skills required of the surveyor are very low. The logical operation process of compensating the measurement data through the horizontal angle sensor can be automatically completed by the program, and the measurement accuracy is extremely accurate. This system can process a large amount of measurement data in batches, and can accurately manage the measurement data to achieve measurement data traceability. The hardware included in this system is compact, easy to install, and has low production cost.

[0107] In summary, the railway signal equipment limit measurement system provided by the present application, through the link of manual measurement by the measuring device, the measuring device has high measurement accuracy, fast measurement speed, high reliability, simple operation and wide use. The whole system is highly intelligent, and the measuring device can automatically perform error correction in a tilted state. In addition, the measurement data in the measuring device can be transmitted to the handheld terminal or uploaded to the cloud for storage by wireless communication or wired communication, wherein the human-computer interaction software carried by the handheld terminal can analyze the measurement results based on the standard data of the limit, and give a prompt message whether it is over-limit. When it is judged that the measured railway signal equipment is over-limit, an over-limit alarm will be issued.

[0108] It should also be noted that the measurement system provided by the present application can be used to measure different types of limits such as building limits after simple modification, and can also be applied to other fields. This shows that the system has strong scalability.

[0109] Optionally, the present application also provides a railway signal equipment clearance measurement method applied to the main control module in the railway signal equipment clearance measurement device in the railway signal equipment clearance measurement system described above. Fig. 9, a flow chart of a railway signal equipment clearance measurement method provided in the present application.

[0110] like Fig. 9 As shown, the railway signal equipment clearance measurement method includes the following steps:

[0111] Step 101, obtaining measurement data collected by a distance measuring unit installed above the rail, the measurement data including: a horizontal distance between the railway signal equipment and the distance measuring unit; a vertical distance between the railway signal equipment and the upper surface of the rail; and a horizontal angle between the distance measuring unit and a reference plane.

[0112] It should be noted that the ranging unit may specifically include a horizontal ranging sensor for measuring the horizontal distance between the railway signal equipment and the ranging unit, a vertical ranging sensor for measuring the vertical distance between the railway signal equipment and the upper surface of the rail, and a horizontal angle sensor for measuring the horizontal angle between the ranging unit and the reference plane.

[0113] Optionally, the main control module in the railway signal equipment clearance measurement device obtains measurement data from the horizontal distance measuring sensor, the vertical distance measuring sensor and the horizontal angle sensor.

[0114] Step 102: judging whether the railway signal equipment clearance measuring device is in a horizontal state according to the horizontal angle, and issuing a first alarm message when the horizontal angle indicates that the railway signal equipment clearance measuring device is not in a horizontal state.

[0115] Optionally, first determine whether the railway signal equipment limit measuring device is in a horizontal state through the horizontal angle collected by the horizontal angle sensor. If it is determined that the railway signal equipment limit measuring device is not in a horizontal state, the main control module will control the railway signal equipment limit measuring device to send an alarm message to remind the tester to re-place the measuring device.

[0116] If the actual on-site environment does not allow the measuring device to be placed horizontally, the main control module will perform corrections through logical operations along with subsequent measurement data.

[0117] Step 103: Use the horizontal distance and the vertical distance to determine the measured distance, and determine whether the measured distance exceeds a preset limit. When the measured distance exceeds the preset limit, a second alarm message is issued.

[0118] The test distance is determined by using the horizontal distance and the vertical distance to judge whether the test distance exceeds the preset limit. When the test distance of the tested railway signal equipment exceeds the preset limit, the main control module controls the measuring device to issue an alarm message.

[0119] The railway signal equipment limit measurement method provided by the present application ensures that the measuring device can be installed horizontally by carrying a horizontal angle sensor. In the case where the measuring device cannot be installed horizontally, the main control module can compensate the measurement data through logical operations, thereby ensuring the accuracy of the measurement data. In addition, the present application can intelligently process the measurement data, reduce manual recording, proofreading and other links, facilitate large amounts of data management, and can also enter the measurement data into a handheld terminal, and can also upload the measurement data to a cloud data center for storage and analysis, thereby ensuring that the measurement data is not easily lost and data traceability can be achieved.

In addition, in the drawings of the device embodiments provided by the present application, the connection relationship between the modules indicates that there is a communication connection between them, which may be specifically implemented as one or more communication buses or signal lines.

[0121] In the above embodiments, all or part of the embodiments may be implemented by software, hardware, firmware or any combination thereof. When implemented by software, all or part of the embodiments may be implemented in the form of a computer program product.
