Description

Technical Field

[0001] The invention belongs to the technical field of traffic engineering and vacuum pipeline maglev traffic line monitoring, and relates to a multi-system intercommunication control device for vacuum pipeline maglev traffic, in particular to a multi-system intercommunication control device for vacuum equipment and pipeline monitoring for vacuum pipeline maglev traffic. Background Art

[0002] Vacuum tube maglev transportation is a new transportation system that uses trains as carriers, uses superconducting magnetic levitation technology to achieve train separation from the ground to eliminate friction resistance, and uses internal near-vacuum pipeline lines to greatly reduce air resistance, thereby achieving a theoretical train speed of more than 1000km / h. Currently, there are several types of vacuum tube maglev transportation monitoring systems:

[0003] The patent application "A Track Dynamic Deformation Monitoring System and Monitoring Method" (application number: CN202211255027.6) provides a topological structure in which sensors set on the waist of the double-sided tracks collect data and the track monitoring server processes the data. When the track deformation reaches a dangerous level, an alarm message is sent to relevant personnel to save manual work. The system can only monitor track deformation, the monitoring data type is single, and it is not suitable for vacuum (low-pressure) pipelines and cannot be effectively monitored.

[0004] The patent application "Vacuum Pipeline Monitoring and Control System and Monitoring and Control" (application number: CN202110065789.9) provides a vacuum pipeline monitoring and control system including a temperature acquisition module, a vacuum acquisition module, a noise acquisition module, a stress acquisition module, and a control module. The real-time acquired temperature, vacuum degree, noise value, and six-way strain value are compared with the threshold value, and the vacuum pump or re-pressure valve is controlled according to the comparison result and the current working condition of the vacuum pipeline. The system only has the monitoring function, without storage and self-test functions, and requires manual control of the vacuum equipment. For the monitoring and control of long pipelines, the manual workload is too large, and the automation and intelligence are not high.

[0005] Based on the above-mentioned existing technologies, in order to achieve long-term monitoring of pipeline structure, pipeline internal environment, and the status of vacuum equipment along the entire line, unified control of vacuum equipment along the entire line, and data exchange with the operation control system and operation and maintenance system, it is urgently necessary to provide a multi-system intercommunication control device for vacuum equipment and pipeline monitoring.

[0022] like Figure 1 As shown, in one embodiment of the present invention, a multi-system intercommunication control device for vacuum pipeline maglev transportation is provided, the device comprising: a pipe beam mechanical property monitoring system, a pipeline environment monitoring system, vacuum equipment, a central control server and a data transmission unit, wherein: the data transmission unit is used to receive the pipe beam mechanical property measurement data with timing issued by the pipe beam mechanical property monitoring system, the pipeline environment monitoring data with timing issued by the pipeline environment monitoring system and the monitoring data of the vacuum equipment, and transmit the received data to the central control server; the central control server is used to send the received pipe beam mechanical property measurement data with timing, the pipeline environment monitoring data with timing and the monitoring data of the vacuum equipment to the operation and maintenance system for storage of the original data; the central control server also includes a data processing unit and a control unit, the data processing unit is used to filter and average the pipe beam mechanical property measurement data with timing and the pipeline environment monitoring data with timing and then send them to the operation and control system; the data processing unit is also used to normalize the monitoring data of the vacuum equipment and then send it to the operation and control system; the control unit is used to perform intelligent control and safety logic locking on the vacuum equipment of the entire line after receiving the control instruction sent by the operation and control system.

[0023] In the embodiment of the present invention, data are processed into data with timing for time unification, thereby ensuring better unified control of various components.

[0024] For example, the mechanical performance measurement data of the pipe beam with timing includes: static strain, dynamic strain, triaxial acceleration, biaxial inclination and beam end displacement. The pipeline environment monitoring data with timing includes: temperature, humidity, vacuum degree, noise, dust concentration, ammonia concentration and magnetic induction intensity. The vacuum equipment includes: vacuum establishment and maintenance system, gate valve, re-pressurization device, escape maintenance door and head.

[0025] It can be seen from the technical solution of the embodiment of the present invention that by monitoring, storing and processing the pipe beam structure parameters, pipeline environment parameters and vacuum equipment status, it is greatly convenient for the staff to comprehensively judge the current pipe beam structure, pipeline environment and vacuum equipment status, and provide support for subsequent decision-making. The vacuum equipment control system comprehensively controls the equipment of the entire line, reduces the working pressure of the operation and control system, improves the safety of vacuum equipment control, and has a certain level of intelligent automatic control. The embodiment of the present invention provides guarantee for the healthy operation of pipelines and vacuum equipment, greatly reduces the workload of staff, and has high practicality.

[0026] It can be seen that the embodiment of the present invention fully considers the working characteristics of vacuum pipeline maglev transportation, identifies the vacuum pipe beam structure, pipeline environment, and vacuum equipment status, and relies on multiple monitoring methods to achieve full-line status monitoring of the vacuum pipeline. On this basis, data is exchanged with the operation control system, operation and maintenance system, and vacuum equipment, and status monitoring information and test data are transmitted to the operation control system and operation and maintenance system, and control instructions from the operation control system are received, thereby controlling the vacuum equipment on the entire line to automate its operation, reduce the workload of personnel, and have high practicality.

[0027] According to an embodiment of the present invention, the data transmission unit is a core switch.

[0028] In the above embodiment, the core switch is also used to receive control instructions sent by the central control server, transmit them to the vacuum equipment control system, and control the operation of the vacuum equipment.

[0029] Specifically, the core switch receives the monitoring data from the pipe beam mechanical properties monitoring system, pipeline environment monitoring system, and vacuum equipment monitoring system through data communication cables, vacuum communication flanges, various sensors, and transmits it to the central control server for information classification and processing; at the same time, it receives the vacuum equipment actuation control instructions from the central control server and transmits them to the vacuum equipment control system to control the vacuum equipment.

[0030] In the above embodiment, the monitoring data of the vacuum equipment is normalized and then sent to the operation control system, which specifically includes: after the data processing unit collects the monitoring sensor data of each individual vacuum equipment, it automatically determines whether each device is actuated in place and whether the vacuum degree reaches the target value, and normalizes the equipment actuation status information and vacuum degree information, and sends them to the operation control system for control decision-making and simplifying the judgment basis.

[0031] In the above embodiment, in order to ensure more comprehensive and effective control of the vacuum equipment, the intelligent control and safety logic locking of the vacuum equipment of the entire line are carried out, specifically including: the central control server performs single-point control or automated control of the vacuum equipment with continuous actuation steps according to the received control instructions, and implements logical locking on unrelated vacuum equipment when each step is executed.

[0032] That is, the central control server includes data input and output interfaces, storage media, data storage and extraction algorithms, data processing software, vacuum equipment intelligent control software, etc., and is the information storage, processing, distribution, reception, and control equipment of the whole system. The central control server is connected to the operation and control system and the operation and maintenance system through data transmission optical cables, and sends various types of monitoring data directly to the operation and maintenance system for storage. After corresponding processing of different types of monitoring data, it sends them to the operation and control system, receives instructions from the operation and control system, and performs intelligent control and safety logic locking on the vacuum equipment of the whole line. When the vacuum pipeline maglev transportation system is in operation, it manages the actuation of the vacuum equipment of the whole line. When each step is executed, the irrelevant vacuum equipment is logically locked to prevent the malfunction of irrelevant vacuum equipment and enhance the safety of the system. The central control server is also used for single-point control or automatic control of vacuum equipment with continuous actuation steps. For example, the vacuum degree in the pipeline of the vacuum pipeline maglev transportation system, according to the vacuum degree sensor and valve status sensor arranged in the pipeline, according to the set pressure range, automatically controls the vacuum establishment and maintenance system and the opening and closing of each valve along the line, so that the pressure in each section of the vacuum pipeline is maintained stably.

[0033] In summary, the control device of the embodiment of the present invention coordinates the monitoring of the mechanical properties of the pipe beams, pipeline environment monitoring, vacuum equipment monitoring, and vacuum equipment control of the entire line. After various types of monitoring data are processed by the central control server, they are classified and sent to the operation control system and the operation and maintenance system for control decision making, information display, storage, etc. After the operation control system issues a control instruction, it is processed by the central control server to enable the corresponding vacuum equipment to work, and perform necessary interlocking control on the remaining vacuum equipment, and according to the requirements of the workflow, the vacuum equipment with continuous actuation steps is automatically controlled. The entire set of devices improves the integration of information and commands related to the vacuum pipeline, and can interact with the operation control system and the operation and maintenance system for data, thereby improving the integration, convenience, and safety of the vacuum pipeline control of the vacuum pipeline maglev transportation.

[0034] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0035] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
