Description

Technical Field

[0001] The invention relates to the technical field of underground mine traffic management, and in particular to an underground intelligent traffic command system based on infrared sensing. Background Art

[0002] In modern mining operations, transportation within the mine is a key link to ensure production efficiency and safety. Vehicles are often used in mines to transport and move a variety of materials such as ores, equipment, and personnel. However, since the underground working environment is usually small, vehicle transportation is limited by space, resulting in a greater risk of collision accidents; at the same time, under high-density working conditions, traffic congestion is prone to occur, which reduces transportation efficiency and makes it very difficult to reasonably schedule vehicle driving and working time.

[0003] Traditionally, underground traffic management relies on manual scheduling and limited signal light control, which is not only inefficient but also difficult to cope with complex dynamic changes. With the development of information technology, intelligent traffic management systems have gradually been applied to the field of ground transportation, but these systems are not fully applicable to the special working environment underground. For example, GPS positioning cannot work effectively in underground environments, and other wireless communication methods may affect their stability and reliability due to factors such as the complex internal structure of the mine and severe electromagnetic interference. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the fact that the underground working environment is usually small, traffic congestion is prone to occur under high-density working conditions, thereby reducing the transportation efficiency, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide an underground intelligent traffic command system based on infrared sensing.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an underground intelligent traffic command system based on infrared sensing, comprising a vehicle information collection subsystem, a traffic light control subsystem, a vehicle intelligent dispatching subsystem and a power supply and distribution subsystem, wherein the vehicle information collection subsystem automatically collects vehicle information through infrared sensors and uploads it to the vehicle intelligent dispatching subsystem for analysis and processing;

[0008] The traffic light control subsystem receives traffic information instructions from the upper equipment and controls the status of traffic lights on each road section;

[0009] The vehicle intelligent dispatching subsystem can store and analyze traffic light status, vehicle status and traffic information; the power supply and distribution subsystem provides a stable power supply to ensure the normal operation of the entire system.

[0010] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the vehicle information collection subsystem further includes a controller, a fiber optic transceiver, a switch and a signal decoder hardware device, as well as control software for realizing intelligent perception and information transmission functions.

[0011] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the traffic light control subsystem adopts a regional message queue bus to connect the signal control units of each intersection, so that the lower-end device can parse the instructions from the upper-end device and adjust the status of the traffic light according to the predetermined logic.

[0012] As a preferred solution of the underground intelligent traffic command system based on infrared sensing described in the present invention, the vehicle intelligent scheduling subsystem is composed of a server, an industrial computer, and system software. It can not only intelligently schedule the status of each traffic light through the uploaded information, but also store and analyze various traffic data, and finally display it in the form of charts.

[0013] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the power supply and distribution electronic system installs a UPS power supply on the ground. When there is a problem with the power supply in the mine, the power supply and distribution electronic system can ensure that the intelligent traffic command system continues to operate normally for at least 4 hours.

[0014] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the intelligent traffic command system also includes a license plate recognition module and a real-time video monitoring module, which are used to capture and identify the license plate information of passing vehicles, and provide real-time video streams to assist traffic management and safety supervision.

[0015] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the data of the license plate recognition module and the real-time video monitoring module are directly input into the vehicle intelligent dispatching subsystem, and after analysis and processing, are used to generate information such as speeding alarm and wrong vehicle warning.

[0016] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the intelligent traffic command system also includes an integrated management platform, which provides an API interface for integration with other systems and is responsible for data management, log recording, background operations, authority setting, access management, and control management functions to support the overall operation and maintenance of the system.

[0017] As a preferred solution of the infrared sensing-based underground intelligent traffic command system described in the present invention, the comprehensive management platform also integrates intelligent decision-making and smart early warning functions to make optimal path planning or issue potential risk warnings in advance based on the collected data.

[0019] Beneficial effects of the present invention: The present invention monitors and analyzes the entry and exit and operation of underground vehicles in real time. When abnormal conditions such as illegal speeding are detected in the vehicle, the system can respond quickly and send out an alarm signal, effectively preventing possible collision accidents and greatly improving the safety of operators and equipment. The system realizes the dynamic scheduling of underground traffic, and can flexibly adjust the status of traffic lights in each section according to the real-time traffic conditions, thereby reducing the occurrence of traffic congestion, ensuring the smooth flow of transportation channels, and improving the overall transportation efficiency. Since the waiting time and fuel consumption caused by traffic jams are reduced, and the maintenance costs and other indirect losses caused by the reduction of accident rates are reduced, the operating costs of the entire mining enterprise can be effectively controlled. The degree of automation is high, and most of the work is automatically completed by the system, such as data collection, traffic light control, vehicle scheduling, etc., which not only reduces the workload of staff, but also avoids operational errors caused by human factors. As an important part of the intelligent mine, the system provides strong support for the realization of comprehensive intelligence of mines. It is integrated with other intelligent technologies to further improve the automation level of mine production and promote the transformation of traditional mining to intelligence. The system can store and analyze information such as signal light status, vehicle status, and vehicle flow, and display it to users in the form of charts, so that managers can better grasp the real-time status and historical trends of mine traffic, and provide a scientific basis for formulating more reasonable production plans and emergency plans. Equipped with a ground-mounted UPS uninterruptible power supply, when there is a problem with the power supply in the mine, it can ensure the normal operation of the intelligent traffic command system for at least 4 hours, ensuring that basic traffic management functions can still be maintained in an emergency, and enhancing the reliability and risk resistance of the system.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1, reference Figure 1-2 , which is the first embodiment of the present invention, provides an underground intelligent traffic command system based on infrared sensing, including, aiming to optimize the internal traffic management of the mine, improve transportation efficiency, and ensure driving safety. The system mainly includes a vehicle information collection subsystem, a traffic light control subsystem, a vehicle intelligent dispatching subsystem, and a power supply and distribution subsystem.

[0028] Specifically, the vehicle information collection subsystem, traffic light control subsystem, vehicle intelligent dispatching subsystem and power supply and distribution electronic system, wherein the vehicle information collection subsystem automatically collects vehicle information through infrared sensors and uploads it to the vehicle intelligent dispatching subsystem for analysis and processing;

[0029] Furthermore, the traffic light control subsystem receives traffic information instructions sent by the upper device and controls the status of the traffic lights on each road section;

[0030] Furthermore, the vehicle intelligent dispatching subsystem can store and analyze traffic light status, vehicle status and traffic information; the power supply and distribution subsystem provides a stable power supply to ensure the normal operation of the entire system.

[0031] Operation process: The vehicle information collection subsystem is equipped with a highly sensitive infrared sensor to automatically detect each passing vehicle and record its basic information such as speed, location, direction, etc. In addition, the license plate recognition module is responsible for capturing and identifying the license plate information of passing vehicles. The collected data is sent to the signal decoder through the optical fiber transceiver and switch for preliminary processing, and then uploaded to the vehicle intelligent dispatching subsystem. After receiving the control instructions generated by the vehicle intelligent dispatching subsystem, the traffic light control subsystem parses and transmits them to the signal controllers at each intersection. The signal controllers at each intersection adjust the color of the corresponding traffic lights according to the received instructions to guide vehicles to pass safely and orderly. After receiving the data from the vehicle information collection subsystem, the vehicle intelligent dispatching subsystem uses the built-in algorithm to evaluate the current traffic conditions and determine whether there are potential safety hazards or congestion risks. Based on the analysis results, the subsystem decides whether it is necessary to adjust the status of the traffic light (such as changing the red light to green light) or issue a warning notification (such as speeding alarm). If necessary, it will also plan the optimal driving path to guide vehicles to avoid peak sections. All information about vehicle status, traffic flow and signal light status will be stored for subsequent query and analysis. The integrated management platform regularly generates detailed traffic operation reports, including key indicators in the form of charts, to help managers understand the overall situation of mine traffic and provide a reference for future improvement measures. To ensure the stable operation of the entire system, the UPS power supply in the power distribution subsystem provides the necessary power support at startup, ensuring that the system will not be interrupted even in the event of a main power failure. In addition, each component in the system undergoes regular health checks to ensure that they are in optimal working condition.

[0032] In summary, the infrared sensing-based underground intelligent traffic command system of the present invention realizes the effective management and optimization of internal traffic in the mine by integrating the vehicle information collection subsystem, traffic light control subsystem, vehicle intelligent dispatching subsystem and power supply and distribution subsystem, thereby improving work efficiency and safety.

[0033] Example 2, reference Figure 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that, compared with the first embodiment, this embodiment is optimized in hardware configuration and software functions to achieve more efficient traffic management and higher reliability.

[0034] Specifically, the vehicle information collection subsystem further includes a controller, a fiber optic transceiver, a switch and a signal decoder hardware device, as well as control software for realizing intelligent perception and information transmission functions. The subsystem can efficiently collect and process mine traffic information.

[0035] Furthermore, the traffic light control subsystem uses a regional message queue bus to connect the signal control units of each intersection, so that the lower-end device can parse the instructions from the upper-end device and adjust the state of the traffic light according to a predetermined logic.

[0036] Furthermore, the vehicle intelligent dispatching subsystem is composed of a server, an industrial computer, and system software. It can not only intelligently dispatch the status of each traffic light through the uploaded information, but also store and analyze various traffic data, and finally display them in the form of charts.

[0037] Furthermore, the power supply and distribution electronic system is equipped with a UPS power supply on the ground. When there is a problem with the power supply in the mine, the power supply and distribution electronic system can ensure that the intelligent traffic command system can continue to operate normally for at least 4 hours.

[0038] The rest of the structure is the same as that of Example 1.

[0039] Operation process: In addition to the original infrared sensor, the vehicle information collection subsystem further integrates hardware devices such as controllers, fiber optic transceivers, switches and signal decoders. These components work together to ensure that the entire process from data collection to preliminary processing and then to transmission is more efficient and accurate. The subsystem is also equipped with specially designed control software to realize the functions of intelligent perception and information transmission. Through this software, the traffic conditions in the mine can be monitored in real time and any changes or emergencies can be quickly responded to, thereby improving the efficiency and accuracy of data collection. Different from the direct instruction transmission method in the first embodiment, this embodiment uses a regional message queue bus (MQTT) to connect the signal control units at each intersection. This method not only improves the communication efficiency, but also enhances the fault tolerance of the system. Even if a node fails, the other parts can continue to work normally. The lower-end device can receive and parse the instructions from the upper-end device and adjust the status of the traffic lights on each section according to the pre-set logical rules. This allows the traffic flow to be flexibly adjusted according to the actual situation and reduce unnecessary waiting time. The vehicle intelligent scheduling subsystem consists of a server, an industrial computer and a series of system software. It can not only intelligently dispatch the status of each signal light based on the uploaded information, but also deeply analyze various traffic data, including but not limited to traffic volume, driving speed, accident frequency, etc. The analysis results will be presented to users in the form of intuitive charts, providing strong support for decision-making. In order to ensure the stable operation of the entire system, an uninterruptible power supply (UPS) is installed on the ground. When there is a problem with the power supply in the mine, this power supply and distribution electronic system can ensure that the intelligent traffic command system continues to operate normally for at least 4 hours. This greatly improves the system's ability to respond to emergencies and ensures that key tasks are not affected.

[0040] In summary, the second embodiment of the present invention significantly improves the performance and reliability of the underground intelligent traffic command system by optimizing the design of the vehicle information collection subsystem, traffic light control subsystem, vehicle intelligent dispatching subsystem and power supply and distribution subsystem, and brings new solutions to internal traffic management in mines.

[0041] Example 3, reference Figure 1-2 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that: this embodiment introduces a license plate recognition module and a real-time video monitoring module, aiming to enhance the functions of the intelligent traffic command system, especially in capturing and identifying the license plate information of passing vehicles, and providing real-time video streaming to assist traffic management and safety supervision.

[0042] Specifically, the intelligent traffic command system also includes a license plate recognition module and a real-time video monitoring module, which are used to capture and recognize the license plate information of passing vehicles, and provide real-time video streams to assist traffic management and safety supervision.

[0043] Furthermore, the data of the license plate recognition module and the real-time video monitoring module are directly input into the vehicle intelligent dispatching subsystem, and after being analyzed and processed, are used to generate information such as speeding alarm and wrong vehicle warning.

[0044] Furthermore, the intelligent traffic command system also includes an integrated management platform, which provides an API interface for integration with other systems and is responsible for data management, log recording, background operations, permission setting, access management, and control management functions to support the overall operation and maintenance of the system.

[0045] Furthermore, the comprehensive management platform also integrates intelligent decision-making and smart early warning functions to make optimal route planning or issue potential risk warnings in advance based on the collected data.

[0046] Furthermore, all subsystems are interconnected through a high-speed and stable communication network to ensure the timeliness and accuracy of data transmission while having good scalability.

[0047] The rest of the structure is the same as that of Example 2.

[0048] Operation process: Start the UPS power supply in the power distribution electronic system at the mine ground control center to ensure stable and reliable power supply for the entire system.

[0049] Configuration parameters: Set the initial parameters of each subsystem through the integrated management platform, including the sensor sensitivity of the vehicle information collection subsystem, the default signal mode of the traffic light control subsystem, etc., and confirm that the communication connection between all hardware devices is normal. The infrared sensor of the vehicle information collection subsystem starts working, automatically detects each passing vehicle, and records its basic information such as speed, position, and direction. At the same time, the license plate recognition module captures and recognizes the license plate information of passing vehicles. The collected data is sent to the signal decoder through the optical fiber transceiver and switch for preliminary processing, and then uploaded to the vehicle intelligent dispatch subsystem. After receiving the data from the vehicle information collection subsystem, the vehicle intelligent dispatch subsystem uses the built-in algorithm to evaluate the current traffic conditions and determine whether there are potential safety hazards or congestion risks. Based on the analysis results, the subsystem decides whether it is necessary to adjust the status of the traffic light (such as changing the red light to green light) or issue a warning notification (such as speeding alarm). If necessary, it will also plan the optimal driving path to guide vehicles to avoid peak sections. After receiving the control instructions generated by the vehicle intelligent dispatch subsystem, the traffic light control subsystem parses and transmits them to the signal controllers at each intersection. The signal controllers at each intersection adjust the color of the corresponding traffic lights according to the instructions received, so as to guide vehicles to pass safely and orderly. The vehicle information collection subsystem continues to collect the latest traffic data and continuously updates it to the vehicle intelligent dispatch subsystem. Based on the latest data, the vehicle intelligent dispatch subsystem can further optimize previous decisions, such as rescheduling the time interval of the traffic lights or changing the speed limit regulations in certain areas. All information about vehicle status, traffic flow and traffic light status will be stored for subsequent query and analysis. The integrated management platform regularly generates detailed traffic operation reports, including key indicators displayed in the form of charts, to help managers understand the overall situation of mine traffic and provide a reference for future improvement measures. When the system detects any abnormal situation (such as vehicle failure, accident scene), it will immediately trigger the emergency response mechanism. The system will quickly notify the relevant staff and take necessary emergency measures, such as closing the affected area, dispatching rescue teams, etc., and adjusting the traffic rules in other areas to ensure overall traffic safety. Regularly perform health checks on each component in the system to ensure that they are in the best working condition.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
