Description

Technical Field

[0001] The invention relates to a railway traffic management system. Background Art

[0002] With the rapid development of railway construction in China and even around the world, the railway network is constantly expanding, the number of construction projects is increasing, and the scale is getting larger and larger. Therefore, the safety issue of construction sites is particularly prominent.

[0003] Existing safety protection measures at railway construction sites mainly adopt two methods: manual monitoring and physical barriers.

[0004] However, manual monitoring relies on manpower to conduct on-site inspections and supervision, which not only consumes a lot of human resources, but also has difficulty in achieving comprehensive coverage in large-scale, multi-section construction sites. In addition, manual monitoring relies on visual or auditory perception, and the response speed to emergencies is slow, which easily misses the best time to deal with them.

[0005] Physical barriers are inflexible and can restrict access to certain extent, but they are fixed and cannot adapt to the dynamically changing construction environment. In addition, long-term use requires regular inspection and maintenance, which increases operating costs.

[0006] Therefore, whether it is manual monitoring or physical barriers, it is impossible to accurately determine whether an intrusion has actually occurred, and the false alarm rate is high, which affects construction efficiency. It is also difficult to achieve real-time monitoring and immediate warning. Once an unexpected situation occurs, relevant personnel cannot be notified in time to take action. Summary of the invention

[0007] The purpose of the present invention is to overcome the problem that existing railway construction site safety protection measures cannot accurately judge whether an intrusion has actually occurred, have a high false alarm rate, and affect construction efficiency, and provide a railway construction site safety protection system.

[0008] The present invention provides a railway construction site safety protection system, including an electronic fence module, a human-computer interaction module, a site positioning module and a safety risk judgment module;

[0009] Electronic fence module, used to generate electronic fence;

[0010] Human-computer interaction module, used to set the status of the electronic fence;

[0011] The states include open state and closed state;

[0012] On-site positioning module, used to obtain the geographic location of the construction unit;

[0013] The construction unit includes construction personnel and construction equipment;

[0014] The safety risk judgment module is used to obtain the geographical scope and status of the electronic fence and the geographical location of the construction unit;

[0015] When the geographical location of the construction unit is within the geographical range of the electronic fence and the electronic fence is in a closed state, it is determined that the construction unit has a safety risk and a prompt is given.

[0016] Furthermore, the safety risk judgment module is also used to determine that the construction unit has a safety risk and issue a prompt when the distance between the construction unit's geographical location and the boundary of the electronic fence is less than a distance threshold and the electronic fence is in a closed state.

[0017] Furthermore, the human-computer interaction module is also used to obtain the construction plan;

[0018] The construction plan includes the geographic scope and time period of on-site construction;

[0019] And set the electronic fence within the geographical range to an open state during the time period.

[0020] Furthermore, it also includes a field alarm module;

[0021] The safety risk judgment module is also used to generate an alarm signal after judging whether a construction unit has safety risks;

[0022] The on-site alarm module is used to give prompts in the form of sound / light after receiving the alarm signal.

[0023] Furthermore, the human-computer interaction module is also used to display the geographical range and status of the electronic fence.

[0024] Furthermore, the human-computer interaction module is also used to display the construction units and mark the construction units that have safety risks.

[0025] Further, the geographical range of the electronic fence includes an upstream range and a downstream range;

[0026] The upward railway line is located within the upward range, and the upward range is divided into a plurality of upward sections;

[0027] The downlink railway line is located within the downlink range, and the downlink range is divided into a plurality of downlink sections.

[0028] Furthermore, the width of the uplink range and the downlink range are both 4 m.

[0029] The beneficial effects of the present invention are:

[0030] The railway construction site safety protection system and method automatically detects and identifies any construction unit that attempts to enter the enclosure through the electronic fence without manual intervention. When the construction unit deviates from the predetermined working scope and exceeds the set safety boundary, the system will immediately issue an alarm signal to remind the operating construction personnel to take timely measures to ensure construction safety and the correct operation of the equipment. It not only improves construction efficiency, but also greatly reduces the probability of safety accidents. It improves the efficiency and safety of the entire construction process.

[0031] In addition, the layout of the electronic fence can be flexibly adjusted according to changes in the construction site, and is suitable for various complex geographical environments and different construction stages. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention. Specific implementation method 1

[0040] The railway construction site safety protection system of this embodiment includes an electronic fence module 1, a human-computer interaction module 2, a site positioning module 3 and a safety risk judgment module 4;

[0041] The electronic fence module 1 is used to generate an electronic fence;

[0042] Human-computer interaction module 2, used to set the state of the electronic fence;

[0043] The states include open state and closed state;

[0044] On-site positioning module 3, used to obtain the geographical location of the construction unit;

[0045] The construction unit includes construction personnel and construction equipment;

[0046] The safety risk judgment module 4 is used to obtain the geographical range and status of the electronic fence and the geographical location of the construction unit;

[0047] When the geographical location of the construction unit is within the geographical range of the electronic fence and the electronic fence is in a closed state, it is determined that the construction unit has a safety risk and a prompt is issued.

[0048] Specifically, this embodiment provides a railway construction site safety protection system, which can generate an electronic fence that is fully enclosed in both the upstream and downstream directions of the railway line. When there is no construction plan, if construction personnel enter, an alarm can be issued in real time. When there is a construction plan, the electronic fence of the corresponding area will be opened. If abnormal situations such as mistaken entry or intrusion into the adjacent line (or other) electronic fence occur during the operation, an alarm can also be issued in real time, and the alarm information will be pushed to the terminal of the station staff in real time.

[0049] like Figure 1 As shown, the electronic fence module 1 can use an electronic fence device based on the Beidou satellite navigation system, which can achieve sub-meter or even centimeter-level positioning accuracy, and form a virtual electronic fence boundary through the geographic information system (GIS) and satellite positioning data, and upload it to the server for storage and management. The human-computer interaction module 2 obtains the electronic fence data from the server, and displays and interactively controls the electronic fence through the existing electronic fence management software.

[0050] The on-site positioning module 3 is fixed on the construction unit and moves with the construction unit, and can obtain the geographical location of the construction unit in real time. It is also uploaded to the server for storage and management.

[0051] The on-site positioning module 3 can adopt a deviation correction and stabilization algorithm, that is, it keeps calculating the distance to the rail, so as to judge the movement trend of the on-site positioning module 3. If there are points that are inconsistent with the movement trend or have large deviations, the data will be filtered out.

[0052] The safety risk judgment module 4 can obtain the electronic fence data and the geographical location of the construction unit from the server, perform data analysis on the geographical location of the construction unit and the geographical range of the electronic fence, analyze whether the geographical location (point) of the construction unit overlaps with the geographical range (surface) of the electronic fence, and then judge whether the construction unit is within the scope of the electronic fence, and combine the state of the electronic fence (the open state indicates that the construction unit is allowed to enter, and the closed state indicates that the construction unit is not allowed to enter), determine that the construction unit has a safety risk and give a prompt. The prompt information can be a corresponding image and sound alarm through the human-computer interaction module 2, and can push information to the work terminal of the relevant personnel according to the preset trigger mechanism.

[0053] By adopting the above technical solution, the railway construction site safety protection system proposed by the present invention can realize all-round and real-time monitoring of the construction site. This includes not only dynamic monitoring of construction personnel, but also real-time status monitoring of various construction equipment and machinery. Through this comprehensive monitoring method, the system can timely discover potential safety hazards and abnormal situations, so as to quickly take corresponding preventive measures. Specific implementation method 2

[0055] This embodiment is a further explanation of the first embodiment. In this embodiment, the safety risk judgment module 4 is also used to determine that the construction unit has a safety risk and issue a prompt when the distance between the geographical location of the construction unit and the boundary of the electronic fence is less than a distance threshold and the electronic fence is in a closed state.

[0056] The other technical features of this embodiment are exactly the same as those of the first embodiment.

[0057] Specifically, the safety risk judgment module 4 can also take corresponding warning measures according to the movement trend of the construction unit when the construction unit is about to enter the closed electronic fence (based on the preset distance between the geographical location of the construction unit and the boundary of the electronic fence).

[0058] Therefore, the system of this embodiment can also predict and identify possible safety risks in advance through data analysis, and further improve the safety management level of the entire construction site. It can not only ensure the life safety of construction workers, but also effectively protect construction equipment and machinery from damage, thereby improving the safety and efficiency of the entire railway construction site. Specific implementation method three

[0060] This embodiment is a further explanation of the first or second embodiment. In this embodiment, the human-computer interaction module 2 is also used to obtain a construction plan;

[0061] The construction plan includes the geographic scope and time period of on-site construction;

[0062] And set the electronic fence within the geographical range to an open state during the time period.

[0063] The other technical features of this embodiment are exactly the same as those of embodiment one or two.

[0064] Specifically, it can be combined with existing on-site construction management software or office systems. When a new construction plan is created in the on-site construction management software or office system, the construction plan can be pushed to the railway construction site safety protection system of this embodiment, so as to obtain the on-site construction information (geographical scope and time of on-site construction) in the construction plan.

[0065] During construction, the opening and closing of the electronic fence is automatically managed according to the construction plan, and the construction personnel are notified. For example, when there is a construction plan in the upper area, the upper fence is automatically opened, and the fences in other areas remain closed to ensure construction safety. Specific implementation method four

[0067] This embodiment is a further explanation of the third embodiment. In this embodiment, a field alarm module 5 is also included;

[0068] The safety risk judgment module 4 is also used to generate an alarm signal after judging that the construction unit has safety risks;

[0069] The on-site alarm module 5 is used to give a prompt in the form of sound or light after receiving the alarm signal.

[0070] The other technical features of this embodiment are exactly the same as those of embodiment 4.

[0071] Specifically, the on-site positioning module 3 and the on-site alarm module 5 can be combined with the protective clothing of the construction personnel, that is, the on-site positioning module 3, the on-site alarm module 5 and the power supply are added to the protective clothing of the construction personnel.

[0072] The alarm signal generated by the security risk judgment module 4 is sent to the server and transmitted to the on-site alarm module 5 through the wireless communication system.

[0073] Among them, the on-site positioning module 3 and the on-site alarm module 5 can be integrated and can be carried and moved by the construction unit. For example, the on-site positioning module 3, the on-site alarm module 5 and the controller for unified control are integrated on the construction protective clothing.

[0074] The on-site positioning module 3 can adopt a positioning device based on a positioning satellite system such as Beidou.

[0075] The field positioning module 3 can automatically match the nearest reference station based on the received and sent data to improve the accuracy of the data. For example, the field positioning module A starts to match the nearest reference station when it approaches the rail within a certain range and uploads data. When the field positioning module B is used, it determines whether it is within the radius of the field positioning module A (which can be pre-set). If it is within the range, the field positioning module B and the field positioning module A share a reference station. If it is outside the range, it automatically matches the nearest reference station to improve the positioning accuracy.

[0076] The on-site alarm module 5 can adopt a loudspeaker, an LED light strip (which can be pasted to the outside of the protective clothing), or other sound, photoelectric and vibration alarm devices.

[0077] For example, when construction workers mistakenly enter or intrude into the electronic fence, the protective suit's red light will continue to flash as an alarm; when equipment or communication is abnormal, the yellow light will flash slowly as a reminder; when the battery is low, the yellow light will flash quickly at intervals as a reminder. At the same time, the protective suit will also vibrate and sound as an alarm when construction workers mistakenly enter or intrude into the fence. Specific implementation method five

[0079] This embodiment is a further explanation of the first, second or fourth embodiment. In this embodiment, the human-computer interaction module 2 is also used to display the geographical range and status of the electronic fence.

[0080] The other technical features of this embodiment are exactly the same as those of embodiments one, two or four.

[0081] Specifically, the human-computer interaction module 2 obtains the electronic fence data from the server and displays it through the existing electronic fence management software, and can display the electronic fences in different states through preset pictures and icons (including colors).

[0082] like Figures 2-3 As shown, there are both open electronic fences and closed electronic fences, which is more intuitive and easy to understand. Specific implementation method 6

[0084] This embodiment is a further explanation of the fifth embodiment. In this embodiment, the human-computer interaction module 2 is also used to display the construction units; and to mark the construction units with safety risks.

[0085] The other technical features of this embodiment are exactly the same as those of embodiment six.

[0086] Specifically, similarly, the human-computer interaction module 2 also obtains the geographical location of the construction units from the server, and displays each construction unit through preset pictures and icons (including colors).

[0087] like Figure 4As shown, construction units in different states can be displayed in different colors or even different icons (to distinguish between construction personnel and construction equipment). At the same time, construction units in different colors are also a warning measure. Specific implementation method seven

[0089] This implementation mode is a further explanation of implementation modes 1, 2, 3 or 6. In this implementation mode, the geographical range of the electronic fence includes an upstream range and a downstream range.

[0090] The upward railway line is located within the upward range, and the upward range is divided into a plurality of upward sections;

[0091] The downlink railway line is located within the downlink range, and the downlink range is divided into a plurality of downlink sections.

[0092] The other technical features of this embodiment are exactly the same as those of embodiments one, two, three or six.

[0093] Specifically, due to the length of the railway line, it can be divided into large sections according to the station. Figure 4 As shown, the sections are divided according to the management scope of the station. However, in order to avoid the sections being too large, which would cause the electronic fence to fail to play its due role, the sections can be divided according to the construction efficiency of the construction unit, such as dividing the railway line into sections according to the scope of work that the construction unit can do every day. Specific implementation method eight

[0095] This implementation mode is a further explanation of the seventh implementation mode. In this implementation mode, the width of the upstream range and the downstream range are both 4 m.

[0096] The other technical features of this embodiment are exactly the same as those of embodiment seven.

[0097] Specifically, Figure 2 As shown, the standard width of Chinese railways is 1.435m, and a 4-meter-wide electronic fence can provide a buffer zone of approximately 1.2825 meters ((4-1.435) / 2) on one side. This is sufficient for small or temporary construction projects.

[0098] The present invention can also adopt OTA (Over-The-Air) differential upgrade technology, that is, upgrading the device through a wireless network, and differential upgrade means upgrading only the changed part, rather than the entire firmware. The human-computer interaction module 2 configures an upgrade installation package in the server, and then uses OTA differential upgrade technology to upgrade the electronic fence module 1, the human-computer interaction module 2 and the on-site positioning module 3.

[0099] This upgrade method can greatly reduce the time and traffic required for the upgrade, and improve the efficiency and success rate of the upgrade. The differential upgrade suitable for embedded systems is also called incremental upgrade, which is to extract the difference between the source version and the target version through the differential algorithm to make a differential package, and then restore the difference on the source version through the restoration algorithm on the device side, so as to upgrade to the target version. The differential upgrade solution can not only save the internal resource space of the MCU, but also save the download process and power consumption during the download and upgrade process. It greatly reduces the download volume and maintenance costs, and is an efficient, safe and reliable upgrade method that can greatly improve the stability and performance of the device.
