Description

Technical Field

[0001] The present invention relates to the technical field of disaster prevention and rescue in railway tunnels, and more particularly to a disaster prevention, evacuation and rescue electromechanical equipment monitoring system suitable for railway tunnels at high altitudes on plateaus. Background Art

[0002] With the development of science and technology, the requirements for the intelligence, informatization and disaster prevention and rescue of railway tunnels are getting higher and higher. The mileage of railway tunnels continues to grow. By the end of 2021, the operating mileage of China's railways exceeded 150,000 km. Among them, 17,532 railway tunnels have been put into operation, with a length of 21,055 km. There are 2,418 railway tunnels under construction, with a length of 6,414 km. The electromechanical equipment for disaster prevention and rescue on-site in railway tunnels mainly includes emergency lighting fixtures, evacuation indicator lights, fans, air valves, protective doors and fire water extinguishing systems. These electromechanical equipment are distributed throughout the tunnel. The electromechanical equipment for disaster prevention and rescue on-site in railway tunnels is in a "standby" state when the railway is in normal operation, that is, it is not put into use. When a fire occurs in the tunnel, the corresponding electromechanical equipment is lit / started separately / simultaneously according to the process requirements to extinguish the fire / minimize the impact of the fire, ensure the personal safety of passengers and staff, and minimize property losses.

[0003] At present, the monitoring system structure of electromechanical equipment for disaster prevention and rescue in railway tunnels includes a control-based monitoring system (mainly controlling the start / stop of electromechanical equipment). This monitoring method can monitor few parameters and provides limited reference for maintenance and emergency. Some are mainly monitoring, with few and limited control functions, especially in the special environment of railway tunnels (temperature, humidity, altitude, vibration). The stability of controlling high-power electromechanical equipment is questionable. Some types of electromechanical equipment have their own monitoring system, which is independent of the monitoring system of other types of electromechanical equipment, and equipment linkage cannot be achieved. The monitoring systems between some stations are independent of each other, and information sharing and overall scheduling are difficult to achieve. This brings inconvenience to the overall implementation of emergency rescue in railway tunnels.

[0004] In particular, the tunnel is dimly lit and poorly ventilated. Once various accidents occur, it is very inconvenient to evacuate personnel and rescue forces. In particular, tunnels in plateau mountainous areas are mostly inconvenient for transportation and communication and are located in uninhabited areas. Therefore, it is necessary to provide a disaster prevention and rescue electromechanical equipment monitoring system that meets the operation and maintenance management needs of plateau high-altitude railway tunnels, which has become a problem to be solved by peers. Summary of the invention

[0044] 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.

[0045] The embodiment of the present invention discloses a monitoring system for electromechanical equipment for disaster prevention, evacuation and rescue in high altitude railway tunnels on plateaus, such as Figure 1 As shown in the figure, the monitoring system structure is a three-level control system, namely, railway bureau level, station level and on-site tunnel level. A railway bureau manages multiple stations, and each station is equipped with a set of station-level monitoring equipment. A station manages multiple tunnels, and each tunnel is equipped with a set of tunnel-end monitoring equipment. That is, the railway bureau-level monitoring equipment controls multiple sets of station-level monitoring equipment, and each set of station-level monitoring equipment controls multiple sets of tunnel-level monitoring equipment.

[0046] The functions of the railway bureau-level monitoring equipment are to record and archive the data / files of all tunnel electromechanical equipment under its jurisdiction, supervise / inspect the maintenance of electromechanical equipment, release disaster information, coordinate the resources of the stations under its jurisdiction, and coordinate and dispatch the overall response to sudden disasters. The functions of the station-level monitoring equipment are to display on-site data, upload / issue data, report disasters, formulate electromechanical equipment interlocking plans, early warning and execution records of maintenance, and manually intervene in sudden disasters through monitoring terminals when necessary. The functions of on-site tunnel-level monitoring equipment are to collect and upload on-site electromechanical equipment data, upload the status of monitoring equipment in real time, control on-site electromechanical equipment, and provide an interface for manually starting disaster prevention and rescue electromechanical equipment on the tunnel site.

[0047] All the main controllers at the tunnel end and all the station controllers at the station level under the management of the same station are connected through optical fiber to form a ring self-healing industrial Ethernet. The advantage of this ring network is that when a point in the ring network fails, the fault location can be quickly identified and the channel can be switched to another direction of the ring network to achieve self-healing function. The standard Modbus TCP communication protocol is adopted. The station controller can issue control instructions to the main controller under its jurisdiction and upload data of the tunnel electromechanical equipment in real time, thereby achieving the purpose of monitoring the electromechanical equipment in the tunnel.

[0048] All station controllers at the station level under the management of the same railway bureau and all the general database servers at the railway bureau level are connected through optical fiber to form a ring self-healing industrial Ethernet. The standard Modbus TCP communication protocol is adopted to achieve two-way data transmission between the railway bureau-level general database server and the station controllers at the station level.

[0049] like Figure 2 As shown, the bureau-level general database server communication nodes include general database server 1, general database server 2, multiple station controllers, file sharing server, time synchronization server, database server (also known as the first database server), Web server, communication server, SMS server, and multiple monitoring terminals (also known as the first monitoring terminals).

[0050] The main database server 1 and the main database server 2 are backup for each other. When one main database server fails, the other main database server can automatically replace the failed main database server. Reduce the system failure time. The main database server is the core of the entire monitoring system, responsible for managing communications, collecting / processing / storing data, and calculating results by algorithms. The station controller is the core of the station-level monitoring equipment. The file sharing server stores the relevant files of the tunnel disaster prevention and rescue electromechanical equipment, and is a file storage device accessible to all online users. The time synchronization server transmits the acquired standard clock signal information in the network, and the devices such as controllers and servers in the network that need time signals can be synchronized with the standard time source. The unique correspondence between data, alarm information, event information, files, etc. and time in the network is guaranteed. The database server stores the relevant data of the tunnel disaster prevention and rescue electromechanical equipment and the data of the monitoring equipment, which is convenient for historical data review and report generation. The Web server can process requests from Web clients such as browsers and return corresponding responses, and can also place files / data for network users to browse / download. The function of browsing tunnel electromechanical equipment data / files through the Internet is realized. The communication server provides communication services for users on the network who need to transmit tunnel electromechanical equipment files or access information on the monitoring system network through remote communication links. The SMS server combines the enterprise OA system to realize important event / information notifications, file notifications, email arrival reminders, etc. of tunnel disaster prevention and rescue electromechanical equipment, which can be sent in groups and in bulk. The monitoring terminal is an interface for human-computer interaction. Through the monitoring terminal, the staff can view the real-time data, historical data, reports, alarms, and events of the electromechanical equipment; at the same time, they can also issue control instructions to the staff through the monitoring terminal to control the electromechanical equipment on site in the tunnel.

[0051] All station controllers at the station level and all the general database servers at the railway bureau level are connected through optical fiber to form a ring self-healing industrial Ethernet. The standard Modbus TCP communication protocol is adopted. The two-way transmission of data between the general database server at the railway bureau level and the station controllers at the subordinate station level is realized. The general database server is connected to various servers and monitoring terminals through network cables to realize data sharing.

[0052] like Figure 3 As shown, the station-level station controller communication nodes include station controller 1, station controller 2, a file server, a database server (also called a second database server), multiple monitoring terminals (also called second monitoring terminals), and multiple main controllers.

[0053] Station controller 1 and station controller 2 are backup for each other. When one station controller fails, the other station controller can automatically replace the failed station controller. Reduce the system failure time. The station controller is the core of the station monitoring equipment. It is responsible for collecting / processing / storing the data of the electromechanical equipment and monitoring equipment of this station, making electromechanical equipment interlocking decisions according to process requirements, judging equipment risk warning, storing real-time and historical data and other information, transmitting these data to the upper-level monitoring equipment, and sending control instructions of electromechanical equipment to the lower-level monitoring equipment. The file server stores the relevant files of the tunnel disaster prevention and rescue electromechanical equipment of this station, and is a file storage device accessible to all online users of this station. The database server stores the relevant data of the tunnel disaster prevention and rescue electromechanical equipment of this station and the data of the monitoring equipment of this station, which is convenient for the historical data of this station to be checked back. The monitoring terminal is the interface of human-computer interaction at the station level. Through the monitoring terminal, the staff can view the real-time data, historical data, alarms, and events of the electromechanical equipment of this station; at the same time, the staff can also issue control instructions through the monitoring terminal to control the on-site electromechanical equipment of the tunnel of this station. The main controller is the core of the tunnel end monitoring equipment.

[0054] The station controller at the station level is connected to all the on-site master controllers through optical fiber to form a ring self-healing industrial Ethernet. The standard Modbus TCP communication protocol is adopted to achieve two-way data transmission with on-site tunnel-level monitoring equipment. The station controller is connected to the file server, database server and monitoring terminal through a network cable to achieve data sharing.

[0055] like Figure 4 As shown, the tunnel monitoring equipment consists of a main controller, a centralized control panel, a local controller, a control box and an intelligent monitoring device.

[0056] The main controller uses a hard redundant PLC, one for use and one for backup, to reduce the system's failure time. The main controller is responsible for collecting data from electromechanical equipment in the tunnel, monitoring the status of equipment, transmitting data / status to the upper-level monitoring equipment, and receiving instructions from the upper-level monitoring equipment to control the start / stop of electromechanical equipment in the tunnel. Emergency control buttons, status indicators, etc. are set on the centralized control panel to conduct emergency monitoring of important equipment. Its control level is higher than that of each monitoring terminal. When staff discover a disaster / failure on site, they can use the centralized control panel to conduct emergency management of the tunnel; or in an emergency, they can directly operate the buttons on the centralized control panel and use manual intervention to operate the operation mode.

[0057] Based on the distribution of electromechanical equipment in the tunnel, the local controller, control box and intelligent monitoring device are used in conjunction as a local monitoring subsystem and installed near each electromechanical equipment in the tunnel. The software algorithm of the intelligent monitoring device makes up for the shortcomings of PLC in complex data calculation. The intelligent monitoring device also provides temperature sensor calibration, displacement sensor calibration, alarm parameter setting function, vibration sensor type and related parameter setting function, dynamic alarm threshold parameter setting function, and whether the device is offline for alarm. The intelligent monitoring device collects sensor data of on-site electromechanical equipment (fans, air valves, emergency lighting fixtures, evacuation indicator lights, protective doors, fire water extinguishing systems and other electromechanical equipment) in real time, and after analysis and judgment, uploads real-time data, fault alarms, warnings and other information to the local controller / station controller in the form of communication. Combined with other objective data in the tunnel, it can help to carry out scientific and targeted operation and maintenance, rescue planning and task arrangement to improve rescue efficiency and success rate. The local controller uploads the received data to the main controller in the form of communication, and at the same time receives the control signal of the main controller, and together with the control box realizes the start / stop control of the on-site disaster prevention and rescue electromechanical equipment.

[0058] Here are five software algorithms involved in intelligent detection devices:

[0059] ① Convolution operation: The measured device data is convolved with a learnable convolution kernel. The output of the convolution result after the activation function forms the neurons of this layer, thus constituting the feature map of this layer, also known as the feature extraction layer. The input of each neuron is connected to the local receptive field of the previous layer, and the local feature is extracted. Once the local feature is extracted, its positional relationship with other features is determined.

[0060] ② Pooling operation: It divides the input signal into non-overlapping regions, and reduces the spatial resolution of the network through pooling (downsampling) operations for each region. For example, maximum pooling selects the maximum value in the region, and mean pooling calculates the average value in the region. This operation is used to eliminate signal offset and distortion.

[0061] ③ Fully connected operation: After the input data undergoes multiple convolution kernel pooling operations, the output is multiple groups of signals. After the fully connected operation, the multiple groups of signals are combined into one group of signals in sequence.

[0062] ④ Recognition operation: The above operation process is a feature learning operation, which is used to build a training model with good stability. Based on the above operation, according to business needs (classification or regression problems), an additional layer of network is added for recognition operation.

[0063] ⑤ Defacement identification operation: The door body defacement identification algorithm generates a state filter by recursively sampling the door body image, diagnoses the normal and abnormal states of the door body morphology, and continuously corrects the data of micro-deformation of the door body.

[0064] The whole tunnel monitoring system consists of a main controller and several local monitoring subsystems. The main controller is connected to all local controllers / intelligent monitoring devices through optical fiber to form a ring self-healing industrial Ethernet. The standard ModbusTCP communication protocol is adopted. Bidirectional data transmission is realized between all local controllers / intelligent monitoring devices on site. Each local controller and intelligent monitoring device are connected by a network cable to realize data transmission between the two.

[0065] The working process of the present invention is:

[0066] The main controller, local controller and intelligent monitoring device of all tunnel monitoring equipment collect data from on-site electromechanical equipment, analyze, identify and alarm the collected data, display it on the on-site touch screen, and upload the data to the corresponding upper-level station controller through the network interface. The monitoring terminal of the station-level monitoring equipment displays the data of the on-site electromechanical equipment under its jurisdiction. Each station controller uploads the collected data to the general database server of the bureau-level monitoring equipment, which displays / processes / stores the data and calculates the results with algorithms.

[0067] The decisions made by the general database server of the bureau-level monitoring equipment and the operation instructions of the staff through the bureau-level monitoring terminal are issued to the station controller of the corresponding station-level monitoring equipment through the network interface. The station controller issues instructions to the main controller of the corresponding tunnel-end monitoring equipment through the network interface based on the instructions of the general database server and the interlocking requirements of the process equipment of the station. The instructions issued by the staff through the operation terminal of the station-level monitoring equipment can also be issued to the main controller of the corresponding tunnel-end monitoring equipment through the network interface. The main controller issues the received instructions to the corresponding local controller under its jurisdiction through the network interface. The local controller and the control box realize the start / stop control of the on-site disaster prevention and rescue electromechanical equipment.

[0068] The present invention has the following advantages:

[0069] Hierarchical monitoring system: Through the hierarchical structure of railway bureau-level monitoring equipment, station-level monitoring equipment and on-site tunnel-level monitoring equipment, centralized management and overall coordinated scheduling of electromechanical equipment are achieved, thereby improving the efficiency and response speed of the monitoring system.

[0070] Data management and storage optimization: Use the main database server, the first database server, the second database server and other equipment to centrally store and manage the relevant data of the tunnel disaster prevention and rescue electromechanical equipment, which is convenient for historical data review and report generation. At the same time, the relevant files are stored through the file server, making the system more complete and easy to manage.

[0071] Network communication and synchronization mechanism: The introduction of communication servers, SMS servers, time synchronization servers, etc., realizes effective communication and data synchronization between devices in the system, ensuring timely transmission of information and collaborative work between devices.

[0072] Human-computer interaction interface: Through monitoring terminal equipment, it provides real-time data, historical data, reports, alarms, events and other information for viewing, as well as the issuance of control instructions for electromechanical equipment, so that operators can easily monitor and operate the system.

[0073] Self-healing Industrial Ethernet: The ring self-healing Industrial Ethernet structure is adopted to improve the stability and reliability of the system, ensure that the system can automatically repair itself in some abnormal situations, and reduce the possibility of monitoring interruption caused by network failure.

[0074] Real-time monitoring and early warning functions: On-site tunnel-level monitoring equipment collects sensor data of electromechanical equipment in real time through intelligent monitoring devices, and provides setting and calibration functions for parameters such as temperature, displacement, and vibration. Through analysis and judgment, real-time data, fault alarms, and early warning information are sent to upper-level monitoring equipment so that timely responses and measures can be taken, thereby improving the system's safety and disaster prevention and rescue capabilities.

[0075] In summary, this technical solution improves the overall performance and reliability of the railway tunnel disaster prevention and rescue electromechanical equipment monitoring system through features such as layering, centralized management, optimized data storage, network communication, and self-healing structure, making it more suitable for plateau and high-altitude environments.
