[0002] With the rapid development of railway construction, the safety of construction operations has received increasing attention. During railway construction, the risk of safety accidents continues to increase due to the complexity of the construction site environment, the mobility of operators and the frequent operation of trains.

[0003] Traditional safety protection methods for railway construction operations mainly rely on manual inspections and monitoring, which have problems such as limited monitoring range, slow response speed, and insufficient data processing capabilities. In addition, traditional early warning systems can often only monitor a single factor and lack comprehensive safety protection capabilities. Summary of the invention

[0012] Preferably, the early warning protection processing module makes the following judgment when processing the second data: when the train position data indicates that the train is less than 500 meters away from the boundary of the construction warning area and the real-time speed of the train exceeds the allowable speed of the area, the early warning mechanism is triggered.

[0013] Preferably, the early warning and protection processing module performs real-time analysis on the personnel and mechanical equipment location data, and makes the following judgment: when it is detected that any construction worker has stayed continuously within 5 meters around the construction machinery and equipment for more than 5 minutes, or the relative distance between the construction worker and the mechanical equipment is suddenly reduced to within the safe distance, the early warning mechanism is triggered.

[0014] Preferably, the early warning and protection processing module performs the following judgment when processing the environmental information: when the environmental information shows that the visibility is less than 500 meters and is accompanied by continuous rainfall or strong winds, the threshold of the construction warning area boundary is automatically increased.

In addition, the terms "first", "second", "third" and the like are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0021] In the description of this utility, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood by specific circumstances.

[0022] See also Figure 1 The railway construction operation safety protection warning system of the embodiment of the present invention includes: a real-time data monitoring and processing module, which is used to receive and process data information from the TDCS / CTC system, the vehicle-mounted terminal, and the mobile terminal device to generate the first data; a satellite positioning base station management module, which is used to receive and process the positioning information of the train, the person, and the construction area to generate the second data; a communication and interface management module, which is used for vehicle-ground communication and data interaction; an early warning protection processing module, which is provided with a construction warning area boundary, receives the first data and the second data, and compares them with the construction warning area boundary. When one or more of the first data or the second data exceeds or approaches a set threshold, the early warning protection processing module triggers the early warning mechanism.

[0023] In the above embodiment, the system integrates multiple modules such as real-time data monitoring and processing, satellite positioning base station management, communication and interface management, and early warning protection processing, and realizes all-round monitoring and early warning of the construction site through intelligent and automated means. The real-time data monitoring and processing module is one of the cores of the system. It is responsible for receiving and processing data information from the TDCS / CTC system, the vehicle-mounted terminal, and the mobile terminal device. These data information covers key elements such as the running status of the train, the status of the construction area, and the location and behavior of the personnel. By processing these data, the system can generate the first data, which provides a basis for subsequent analysis and early warning. At the same time, the satellite positioning base station management module is also playing an important role. This module can receive and process the positioning information of the train, personnel, and the construction area to generate the second data. These positioning information can not only help the system determine the specific location of each element, but also predict the movement trend of each element and the possible interaction in the future by analyzing parameters such as movement trajectory and speed. The communication and interface management module is the key to realize communication and data interaction between the modules inside the system and between the system and external devices. It ensures that the data generated by the real-time data monitoring and processing module and the satellite positioning base station management module can be accurately transmitted to the early warning protection processing module, and also ensures that the early warning instructions can be sent to relevant equipment and personnel in a timely manner. The early warning protection processing module sets the boundary of the construction warning area and performs comparative analysis based on the received first data and second data. When one or more of the data exceeds or approaches the set threshold, the early warning protection processing module will trigger the corresponding early warning mechanism. These early warning mechanisms include sound and light alarms, mobile device notifications, emergency braking, etc., which aim to gradually improve the safety protection level of the construction site through early warning measures at different levels. Specifically, the early warning protection processing module will adopt different early warning strategies according to different risk levels and early warning conditions. For example, when the train approaches the construction area, the system will determine whether it is necessary to trigger an early warning based on parameters such as the train's speed, acceleration, and distance from the boundary of the construction warning area. If the train speed continues to exceed the speed limit of the construction area or the acceleration suddenly increases, the system will trigger the advanced early warning mechanism and send an emergency braking instruction to the train control system through the communication and interface management module to ensure that the train can stop in time. In addition, the early warning protection processing module will also monitor the personnel and mechanical equipment in the construction area in real time. When it is detected that the relative distance between construction personnel and mechanical equipment suddenly narrows to within the safe distance, the system will automatically determine that there is a potential collision risk, and send an emergency evacuation notice to the relevant construction personnel through the mobile device, and at the same time activate the sound and light alarm device at the construction site to remind personnel to pay attention to safety. Through this series of working principles, the railway construction operation safety protection early warning system realizes comprehensive monitoring and early warning of the construction site. Its advantages are mainly reflected in the following aspects: First, the system is highly automated and intelligent.By integrating multiple modules and advanced algorithms, the system can automatically receive, process and analyze data, and trigger the corresponding early warning mechanism according to the analysis results. This not only greatly improves work efficiency, but also reduces the possibility of human intervention and misjudgment, and improves the accuracy and reliability of early warning. Secondly, the system has a wide range of applicability. Whether it is for trains, construction personnel or mechanical equipment, the system can perform real-time monitoring and early warning. At the same time, the system can also flexibly adjust the early warning strategy and threshold according to different construction environments and operation requirements to ensure the pertinence and effectiveness of the early warning. Thirdly, the system has strong information sharing and coordination capabilities. Through the communication and interface management module, the system can share information and work with other related systems or departments. This makes the safety management of the construction site no longer isolated, but forms an interconnected and coordinated whole, which improves the overall effectiveness of safety management. Finally, the system also has data recording and analysis functions. By recording and analyzing historical data, the system can help managers better understand the safety status and risk distribution of the construction site, and provide strong support for subsequent safety management and decision-making. In summary, the railway construction safety protection early warning system provides a strong guarantee for the safety management of railway construction operations through its efficient, accurate, flexible and collaborative working mechanism. It not only improves the safety protection level of the construction site and reduces the probability of accidents, but also improves work efficiency and management effectiveness.

[0024] Please refer to Figure 1 In another embodiment, the first data includes train status information, construction area status information, personnel and mechanical equipment status information, and environmental information.

[0025] In the above embodiment, the collection and processing of the first data is the basis for the early warning system. The train status information is transmitted to the system in real time through the on-board terminal, including key parameters such as the speed, acceleration, and position of the train. These data can reflect the running status of the train and whether it is close to the construction warning area. The construction area status information covers the layout of the construction area, the progress of the operation, the warning boundary, etc., which helps the system to determine whether the train has entered the construction area and the risk level of the operation. The status information of personnel and mechanical equipment is obtained through positioning base stations and mobile terminal devices, including the location of personnel, the trajectory of movement, and the running status of mechanical equipment. This information is crucial for judging whether there are safety risks for personnel and mechanical equipment. Environmental information is obtained through sensors and meteorological data, including visibility, rainfall, wind speed, etc., which can reflect the environmental conditions of the construction site and provide a basis for early warning decision-making for the system. After obtaining the first data, the early warning protection processing module will conduct a comprehensive analysis of these data. By setting the corresponding thresholds and algorithms, the system can determine whether the train is speeding, whether it is close to the construction warning area, whether there is a risk of collision between personnel and mechanical equipment, and whether the environment is so bad that the construction warning area boundary needs to be adjusted. Once the data exceeds or approaches the set threshold, the early warning protection processing module will trigger the corresponding early warning mechanism, such as sound and light alarm, mobile device notification or emergency braking, to ensure the safety of the construction site. The advantage of this working principle lies in its comprehensiveness and accuracy. First, by integrating multiple information sources, the system can achieve all-round monitoring of the construction site, covering trains, personnel, mechanical equipment and environment, etc., to ensure no blind spots. Secondly, through real-time processing and analysis of data, the system can promptly detect potential safety risks and take corresponding early warning measures before the risk escalates, minimizing the possibility of accidents. In addition, the system can also flexibly adjust the early warning strategy and threshold according to the actual situation and operation requirements of the construction area to adapt to different construction environments and operating conditions.

[0026] Please refer to Figure 1 In another embodiment, the second data includes train position data, personnel and mechanical equipment position data, construction area boundary data and dynamic position change data.

[0027] In the above embodiment, the railway construction operation safety protection early warning system is to monitor and analyze various information data of the construction operation site in real time and accurately to ensure safety during the construction process. Among them, the second data, as an important part of the system, mainly includes train position data, personnel and mechanical equipment position data, construction area boundary data and dynamic position change data, etc., which provide crucial information support for the early warning system. At the railway construction operation site, the satellite positioning base station management module obtains the position data of trains, personnel and mechanical equipment in real time by receiving signals from the satellite positioning system. At the same time, the construction area boundary data provides the system with a clear construction warning area range by preset or real-time update. These position data and boundary data together constitute the main content of the second data. On this basis, the early warning protection processing module analyzes the second data in real time. By comparing the train position data with the construction area boundary data, the system can determine whether the train is approaching or has entered the construction warning area, so as to take corresponding early warning measures. Similarly, by comparing the position data of personnel and mechanical equipment, the system can timely discover the potential collision risk between personnel and mechanical equipment and trigger the corresponding early warning mechanism. In addition, dynamic position change data also provides the system with rich information. By analyzing these data, the system can predict the movement trend of each element and the possible interaction in the future, providing a more scientific basis for early warning decision-making. When one or more of the second data exceeds or approaches the set threshold, the early warning protection processing module will trigger the early warning mechanism. These early warning mechanisms may include sound and light alarms, mobile device notifications, emergency braking and other methods, aiming to gradually improve the safety protection level of the construction site through early warning measures at different levels. First, by acquiring and analyzing the location data of trains, personnel and mechanical equipment in real time, the system can achieve accurate monitoring of the construction site. This accurate monitoring not only improves the accuracy of the early warning, but also provides strong data support for subsequent safety management. Secondly, by setting clear construction area boundaries and dynamically adjusting the early warning threshold, the system can flexibly respond to different construction environments and operation requirements to ensure the effectiveness and pertinence of the early warning strategy. In addition, the diversity of the early warning mechanism also provides multiple guarantees for the safety protection of the construction site, and can take corresponding early warning measures according to different risk levels and early warning conditions to ensure the comprehensiveness and effectiveness of safety management. This working principle also reflects the intelligent and automated characteristics of the system. By integrating advanced satellite positioning technology, data analysis algorithms and early warning processing mechanisms, the system can automatically complete multiple links such as data collection, processing, analysis and early warning without human intervention, greatly improving work efficiency and accuracy. This intelligent and automated feature not only reduces the possibility of human error, but also improves the timeliness and reliability of safety management.In summary, the railway construction safety protection early warning system achieves accurate monitoring and effective early warning of the construction site by acquiring and analyzing the second data in real time.

[0028] Please refer to Figure 1 In another embodiment, after receiving the first data, the early warning protection processing module makes the following judgment: if the train status information shows that the train speed continues to exceed 80% of the speed limit in the construction area and lasts for more than 30 seconds, or the train acceleration suddenly increases and exceeds 0.2m / s 2 , then the early warning mechanism is triggered.

[0029] In the above embodiment, after receiving the first data, a series of judgments and processing will be performed according to the preset rules and algorithms to ensure the safety of the railway construction site. When the train status information in the first data shows that the train speed continues to exceed 80% of the speed limit in the construction area for more than 30 seconds, or the train acceleration suddenly increases and exceeds 0.2m / s 2 When the warning protection processing module triggers the warning mechanism immediately. When the module receives the train status information, it will first parse and identify the data. If the data shows that the train speed continues to exceed 80% of the speed limit in the construction area, and this overspeeding state lasts for more than 30 seconds, the module will determine that the train has a potential risk of overspeeding. Similarly, if the data shows that the train acceleration suddenly increases, and this increase exceeds 0.2m / s 2The module will also determine that the train may have the risk of emergency braking or loss of control. Both situations are considered as conditions for triggering the early warning mechanism. Once the early warning conditions are met, the early warning protection processing module will immediately start the early warning mechanism. This includes sending obvious warning signals through the sound and light alarm system to notify the on-site staff to pay attention to safety; at the same time, the module will also send early warning notifications to relevant personnel through mobile devices or system interfaces so that they can respond quickly. In addition, if the situation is urgent, the module may also directly control the train to perform emergency braking to prevent possible collisions or accidents. First of all, the design of this module fully considers the importance of train status information for safety warning. By setting the thresholds of train speed and acceleration, the module can accurately capture the possible risk status of the train, so as to issue early warnings in time and avoid safety accidents caused by human negligence or misjudgment. Secondly, the early warning protection processing module is highly automated and intelligent. It can automatically analyze, judge and warn after receiving the data without manual intervention, which greatly improves work efficiency and accuracy. At the same time, the module can also flexibly adjust the early warning strategy and threshold according to the actual situation and operation requirements of the construction area to adapt to different construction environments and operating conditions. In addition, the early warning mechanism of the early warning protection processing module is diversified and can meet the needs of different risk levels and early warning conditions. Through various methods such as sound and light alarms, mobile device notifications and emergency braking, the module can ensure the timely transmission and effective processing of early warning information, further improving the safety level of railway construction sites. In summary, by receiving and analyzing the train status information in the first data, the early warning protection processing module can accurately determine whether the train has potential safety risks and take corresponding early warning measures.

[0030] Please refer to Figure 1 In another embodiment, the early warning protection processing module makes the following judgment when processing the second data: when the train position data indicates that the train is less than 500 meters away from the boundary of the construction warning area and the real-time speed of the train exceeds the allowable speed of the area, the early warning mechanism is triggered.

[0031] In the above embodiment, when processing the second data, the module can accurately determine whether the train is close to the construction warning area and whether there is a risk of speeding by accurately analyzing the train position data, the construction warning area boundary data and the real-time speed data of the train. Once the early warning trigger condition is met, the module will immediately start the early warning mechanism to ensure the safety of the construction site. Specifically, the working principle of the early warning protection processing module is as follows: First, the module will receive the train position data transmitted from the satellite positioning base station management module in real time. These data accurately reflect the position and movement state of the train on the railway line. At the same time, the module also has the storage and update function of the construction warning area boundary data, which defines the scope and restrictions of the construction area. After obtaining the train position data and the construction warning area boundary data, the early warning protection processing module will perform real-time data analysis. It will calculate the distance between the current position of the train and the construction warning area boundary, and compare it with the preset safety distance threshold (such as 500 meters). If the distance between the train and the construction warning area boundary is less than this threshold, it means that the train is approaching the construction area and there is a potential safety risk. In addition, the module will also consider the real-time speed data of the train at the same time. It compares the current speed of the train with the speed limit allowed in the construction warning area. If the real-time speed of the train exceeds the allowed speed in the area, it means that the train is not only approaching the construction area, but also at risk of speeding, further increasing the possibility of a safety accident. When the above two conditions are met at the same time, the early warning protection processing module will immediately trigger the early warning mechanism.

[0032] Please refer to Figure 1 In another embodiment, the early warning and protection processing module performs real-time analysis on the location data of the personnel and mechanical equipment, and makes the following judgment: when it is detected that any construction worker has stayed within 5 meters around the construction machinery and equipment for more than 5 minutes, or the relative distance between the construction worker and the mechanical equipment is suddenly reduced to within the safe distance, the early warning mechanism is triggered.

[0033] In the above embodiment, the early warning protection processing module receives the personnel and mechanical equipment location data from the satellite positioning base station management module to grasp the personnel distribution and the location status of the mechanical equipment at the construction site in real time. These data are obtained through positioning technology, with high accuracy and real-time performance, and provide reliable data support for the module's judgment. After obtaining the location data of the personnel and mechanical equipment, the early warning protection processing module will perform real-time analysis. It will first detect whether any construction personnel have stayed in the area within 5 meters around the construction machinery and equipment for more than 5 minutes. The setting of this judgment logic is intended to avoid the safety risks that may be caused by the construction personnel approaching the mechanical equipment for a long time, such as misoperation, collision, etc. Once this situation is detected, the module will immediately determine that there is a potential safety hazard. In addition, the module will also analyze the change in the relative distance between the construction personnel and the mechanical equipment. When it is detected that the relative distance between the construction personnel and the mechanical equipment is suddenly reduced to within the safe distance, the module will also determine that there is a safety risk. This judgment logic can promptly discover and respond to emergencies, such as construction personnel suddenly approaching mechanical equipment or mechanical equipment accidentally moving. When any of the above judgment conditions is met, the early warning protection processing module will immediately trigger the early warning mechanism. Early warning mechanisms may include sound and light alarms, notifications on mobile devices, and warning messages on the system interface. These early warning signals can be quickly conveyed to on-site staff to alert them to potential safety risks and take appropriate measures to avoid accidents.

[0034] Please refer to Figure 1 In another embodiment, the early warning and protection processing module makes the following judgment when processing the environmental information: when the environmental information shows that the visibility is less than 500 meters and is accompanied by continuous rainfall or strong winds, the threshold of the construction warning area boundary is automatically increased.

[0035] In the above embodiment, the threshold of the construction warning area boundary can be intelligently adjusted according to the real-time weather conditions to ensure the safe progress of the construction work. Below, I will elaborate on the working principle and advantages of the early warning protection processing module in processing environmental information. The early warning protection processing module can receive and process environmental information in real time, including key data such as visibility, rainfall intensity, and wind force. These data are usually provided by meteorological monitoring equipment to ensure that the early warning protection processing module can obtain the most accurate and timely weather information. When the early warning protection processing module receives the environmental information, it will immediately analyze and judge the data. If the data shows that the visibility is less than 500 meters and accompanied by continuous rainfall or strong winds, the module will automatically trigger the adjustment mechanism. This is because low visibility, rainfall and strong winds will seriously affect the line of sight and working conditions, increasing the risk of the construction site. In order to cope with this bad weather, the early warning protection processing module will automatically increase the threshold of the construction warning area boundary. Specifically, raising the threshold of the construction warning area boundary means expanding the scope of the warning area and bringing more areas into the safety protection range. This can ensure that under bad weather conditions, construction personnel and mechanical equipment can maintain a sufficient safety distance to avoid collisions or other safety accidents. At the same time, expanding the warning area can also remind construction workers to pay attention to weather changes, strengthen safety protection measures, and ensure the smooth progress of construction work.

[0036] Please refer to Figure 1 In another embodiment, the early warning and protection processing module is provided with a time prediction model for predicting the time when the train approaches the boundary of the construction warning area within a certain period of time in the future based on the train status information and the construction area status information.

[0037] In the above embodiment, by setting a time prediction model, according to the train status information and the construction area status information, the time when the train approaches the boundary of the construction warning area in the future is predicted. This function not only improves the intelligence level of the early warning system, but also makes the safety protection of construction operations more accurate and efficient. First, the early warning protection processing module receives the train status information and construction area status information from different data sources in real time. The train status information includes dynamic data such as the real-time position, speed, acceleration, etc. of the train, which are obtained by satellite positioning, sensors and other technical means, and can reflect the real-time operation status of the train on the railway line. The construction area status information covers static data such as the boundary position, length, width of the construction warning area, as well as dynamic data such as the status of construction equipment and the distribution of construction personnel, which are collected and transmitted through the monitoring system and sensor network of the construction site. After obtaining this information, the early warning protection processing module will input it into the time prediction model. The time prediction model is a mathematical model based on machine learning or statistical principles, which can learn and simulate the law of trains approaching the boundary of the construction warning area by analyzing historical data and real-time data. The model will comprehensively calculate the time when the train may approach the boundary of the construction warning area in the future based on the current position and speed of the train, the layout of the construction area, the status of the construction equipment and other factors. The core of the time prediction model lies in its algorithm and calculation process. The selection and optimization of the algorithm directly affect the accuracy and reliability of the prediction results. Common algorithms include regression analysis, neural network, time series analysis, etc. These algorithms can be selected and adjusted according to actual conditions. During the calculation process, the model will consider a variety of factors, such as the acceleration change of the train, the length and width of the construction area, the moving speed of the construction equipment, etc., to predict the time when the train approaches the boundary of the construction warning area as accurately as possible. Through the time prediction model, the early warning protection processing module can predict the risk of the train approaching the boundary of the construction warning area in advance, thereby providing strong support for the safety protection of construction operations. When the prediction results show that the train will approach the boundary of the construction warning area in the future, the module will immediately trigger the early warning mechanism and send early warning information to relevant personnel to remind them to take corresponding safety measures. The sending method and content of the early warning information can be customized according to actual conditions. For example, an alarm can be sounded at the construction site through an audible and visual alarm device, and the early warning information can be sent to construction personnel and management personnel through mobile phone text messages, e-mails, etc. The early warning information should include the estimated time when the train approaches the boundary of the construction warning area, the specific location of the construction area, the safety measures that need to be taken, etc., so that relevant personnel can quickly understand the situation and respond. In summary, the early warning protection processing module sets a time prediction model to predict the time when the train approaches the boundary of the construction warning area in the future based on the train status information and the construction area status information.This working principle enables the early warning system to predict safety risks in advance, providing strong guarantees for the safety protection of construction operations.

[0038] Please refer to Figure 1 In another embodiment, the early warning and protection processing module performs real-time tracking and pattern recognition on the dynamic position change data, and makes the following judgment: when it is detected that the moving trajectory of a train, personnel or mechanical equipment shows a trend of crossing or approaching the boundary of the construction warning area, the system will construct a moving trajectory prediction model based on historical data and real-time data.

[0039] In the above embodiment, the safety risks in the construction warning area are predicted and evaluated to ensure the safe and efficient progress of railway construction operations. First, the early warning protection processing module will track the dynamic position change data of trains, personnel and mechanical equipment in real time. These data are obtained through various technical means such as satellite positioning and sensor networks, and can accurately reflect the real-time position and movement status of various entities in the construction area. The module processes these data efficiently, extracts key information, and provides data support for subsequent pattern recognition and trajectory prediction. After obtaining the dynamic position change data, the early warning protection processing module will perform pattern recognition. Pattern recognition is a method of discovering hidden patterns or laws in data through data analysis. Here, the module will use advanced algorithms and models to conduct in-depth analysis of the movement trajectories of trains, personnel and mechanical equipment, and identify their movement laws and behavioral characteristics. This step helps to discover potential safety risks and provide a basis for the subsequent triggering of the early warning mechanism. When the early warning protection processing module detects that the movement trajectory of the train, personnel or mechanical equipment is intersecting or approaching the boundary of the construction warning area, the system will immediately enter a high alert state. At this time, the module will build a movement trajectory prediction model based on historical data and real-time data. This model combines the principles of machine learning and statistics. Through training and optimization of a large amount of historical data, it can accurately predict the movement trajectory of various entities in the future. In the process of building the movement trajectory prediction model, the early warning and protection processing module will fully consider a variety of factors, including dynamic parameters such as the speed, acceleration, and direction of the entity, as well as static parameters such as the layout and size of the construction warning area. Through comprehensive analysis of these parameters, the module can generate accurate trajectory prediction results and provide a scientific basis for the triggering of the early warning mechanism. Once the movement trajectory prediction model predicts that the train, personnel or mechanical equipment may cross or approach the boundary of the construction warning area, the early warning and protection processing module will immediately trigger the early warning mechanism. The early warning mechanism includes but is not limited to sound and light alarms, SMS notifications, email reminders and other methods, aiming to promptly convey safety risk information to relevant personnel so that they can quickly take countermeasures to avoid safety accidents. In addition, the early warning and protection processing module will also adjust and optimize the movement trajectory prediction model in real time according to the triggering of the early warning mechanism.

[0040] Please refer to Figure 1 In another embodiment, the warning mechanism includes primary warning, intermediate warning, advanced warning and emergency braking.

[0041] In the above embodiment, when the system detects a possible risk signal, it will first trigger a primary warning, and issue a warning to relevant personnel through sound and light prompts, reminding them to pay attention and make a preliminary judgment on the risk situation. If the risk develops further, the intermediate warning will be activated. At this time, the system will transmit risk information to more relevant personnel through more direct methods such as text messages and emails, and recommend corresponding measures. If the risk is still not under control, the advanced warning will be activated. At this time, the system will issue a stronger warning and may automatically take some preventive measures, such as restricting access to some areas. Finally, if the risk reaches an emergency level, the system will activate emergency braking and directly intervene and prevent possible risk events through automatic control means, such as an automatic emergency braking system. The working principle of the entire early warning mechanism is a continuous and dynamic process, which aims to gradually strengthen risk prevention and control through different levels of early warning and response measures to ensure the safety of railway construction operations.
