Drawings
The technical solution of the present invention is explained in detail below with reference to the accompanying drawings, in which:
fig. 1 shows a schematic block diagram of a gas pipeline safety monitoring system according to an embodiment of the present invention.
Detailed Description
The features and technical effects of the technical scheme of the invention are described in detail below with reference to the accompanying drawings and by combining with the exemplary embodiments, and a high-efficiency gas pipeline safety monitoring system is disclosed. It is noted that like reference numerals refer to like structures and that the terms "first", "second", "upper", "lower", and the like as used herein may be used to modify various structures. These modifications do not imply a spatial, sequential, or hierarchical relationship to the structures being modified unless specifically stated.
As shown in fig. 1, the gas pipeline safety monitoring system according to the preferred embodiment of the present invention at least includes an equipment data interface module, an analysis service interface module, a maintenance order module, a map support module, a visualization module, a service sharing module, and a partition management module interacting with the above modules.
The device data interface module is communicated with data collectors arranged on or near gas pipelines such as a pressure regulator, a valve well and the like, and acquires pipeline safety data including but not limited to pressure, temperature, impurity content (such as humidity), gas concentration (such as natural gas volume ratio) and the like in the pipelines in real time from various devices on the gas pipelines. Preferably, the device data interface module receives the pipeline security data of the analog signal and converts the analog signal into a digital signal by using an analog-to-digital converter (ADC) arranged in the module so as to be used by the third-party service system call.
The analysis service interface module receives pipeline security data from the equipment data interface module and preferably receives fault event analysis mode parameters either manually from an operator or automatically from a third party business system, for example, a GIS blast (shut-off valve) analysis algorithm is issued as a service interface from which the use of blast analysis functionality in a previous GIS system can be translated to other business systems (including emergency handling and rapid shut-off valves in a drilling process, including gas shut-off affected pipeline areas in a gas shut-off management subsystem, and other functions in third party software, etc.) through which the use of shut-off valve analysis functionality can be developed. That is, the analysis service interface module identifies whether a certain device has a potential safety hazard event such as a pipe burst according to the pipe safety data sent by the device data interface module and the failure event analysis mode parameters received from the outside, for example, compares the potential safety hazard event with a threshold value pre-stored or set inside, determines that a pipe burst event occurs if the potential safety hazard event exceeds the threshold value, forwards information such as a device number, a position, pipe safety data and the like corresponding to the pipe burst event to the partition module, and immediately tries to directly send a valve closing instruction to the device. If the instruction for closing the valve is executed correctly, only the position information of the closed equipment such as the valve is fed back to the partition management module, and if the instruction for closing the valve is not executed successfully, the information of the equipment such as the number and the position of the valve, the pipeline safety data and the like and a closing failure code are sent to the partition management module, and subsequent management operation is carried out by the partition management module.
The parameters used by the analysis service interface module are illustrated as follows:
EA1 primary tube explosion analysis method
EA2 secondary tube explosion analysis method
EA3 method for analyzing tube explosion once to return the influence on the number of key units and buildings
ObjectId selection device Objectid
Selecting device layer table name
IsMustCLOSE valve whether to perform air source tracking analysis, true or false
Invalidvalues failed device unable to shut down 3331 Value; 3332, Value.
The map support module stores or is associated with a gas pipeline safety monitoring map based on a GIS system, such as a database stored locally, or is externally connected with a third-party map system, such as a Baidu, Gaode, dog search, Tencent map and the like, and is responsible for providing real-time information of the gas pipeline, including the distribution position of the gas pipeline, the current state of each pipeline, the current position of maintenance personnel, the traffic state around the pipeline, the local weather state around the pipeline and the like, to the partition management module. The concept of the periphery can be measured according to a certain distance, such as a straight distance within 5 km, 3 km and 1 km, or can be a time-consuming range of different routes in different transportation modes, such as driving for 5 minutes, riding for 10 minutes, walking for 15 minutes, and the like. The map support module responds to the analysis service interface module to judge that the pipe explosion event exists, sends the data to the partition management module, and updates the data in time after the partition management module sends out a maintenance order or a service sharing instruction.
The visualization module can be a large touch screen formed by splicing a plurality of OLED touch display screens installed at the control center, can also be a small and medium touch screen installed on a maintenance personnel vehicle or wearable equipment, and can also be a map subsystem of a vehicle loading system of the maintenance personnel vehicle or a map application (app) on the wearable equipment of the maintenance personnel. And the visualization module visually displays the security inspection results (inspected green, undetected gray and hidden danger red) in the whole city in a GIS map visualization mode. Preferably, when a maintenance person approaches a faulty pipeline device, the visualization module automatically searches all public display screens or private shared display screens around the pipeline device (as described above) where the pipe explosion event occurs, such as a billboard of a station, a dock or a waiting room, for example, an LED display board of a bus or a taxi, and instructs these third party display devices to point at the position of the pipeline device with a conspicuous mark, for example, a red flashing arrow, which is beneficial to shortening the time for the maintenance person to reach the designated position and timely and effectively reducing the pipe explosion loss. Therefore, the visualization module not only interacts data with the partition management module in the gas pipeline safety monitoring system, but also further interacts data with a third-party service system (such as a city emergency management system, a bus/taxi operation dispatching system, an airport/station/wharf management system, and the like), so that the interoperability and convenience of the safety monitoring system can be greatly expanded.
The partition management module responds to the equipment failure/fault information (including serial numbers, positions, valve closing success/failure states and the like) sent by the analysis service interface module, calls real-time gas pipeline information contained in a gas pipeline safety monitoring map from the map support module, comprehensively judges to obtain an optimal (for example, shortest time consumption or lowest cost) maintenance scheme, sends a maintenance instruction to the maintenance dispatch module, and simultaneously issues the GIS service to the service sharing module. The service instructions include information including service personnel code, location, number of malfunctioning devices, location, pipeline safety data, service plan operational procedures and tools involved, etc. And after the offline map and the overlapped GIS management network after coordinate conversion are overlapped, releasing GIS service, and sharing the GIS service to each service subsystem in a service mode, wherein the GIS service comprises management network inspection, winter supply specialization, indoor maintenance, indoor security inspection and the like.
And the maintenance dispatching module forwards the maintenance instruction to corresponding maintenance personnel according to the maintenance scheme indicated by the partition management module and informs the maintenance personnel to process the fault event as soon as possible. In particular, for maintenance personnel in noisy environments such as downtown areas, the commonly used video and audio reminders are easily masked by the ambient light/sound noise, and for this purpose, a haptic module (e.g., a vibrator) may be used to send out a specific pattern of vibration reminders to the maintenance personnel. Preferably, the alarm may also detect the environment in which the service person is located using various sensors (e.g., light, sound, vibration, etc.) integrated with a smart device carried with the service person, and initiate the vibration alert at a first amplitude and/or first time if the ambient noise is greater than a first, lower threshold, and at a second, greater amplitude and/or second time if the ambient noise is further greater than a second, higher threshold. In particular, if the ambient noise is greater than the highest third threshold, the pain module (e.g., the acupuncture or shock module) is activated to apply sufficient pain alerts to the maintenance personnel to avoid the maintenance personnel missing significant state changes of the system.
The service sharing module interacts with, for example, a dispatch center of a gas company, for example, applies for a call for a special maintenance device to a logistics device department, applies for a maintenance notification to a communication facilitator to send a maintenance notification to a gas user within an area affected by a fault event, applies for a cooperative process (e.g., visual guidance of a shared screen) to a city emergency management system, a bus/taxi operation dispatch system, an airport/station/terminal management system, and the like.
Through adopting above-mentioned gas pipeline safety monitoring system, can obtain following technological effect:
(1) on a GIS-based large platform, all information related to a gas pipe network is visually displayed, so that comprehensive information sharing and upstream and downstream free cooperation are realized;
(2) the processing progress, state and feedback result of the work related to the use safety of the gas pipe network can be intuitively controlled and checked in the whole process, so that the control in advance and the tracing back after the fact are realized;
(3) the information collected and fed back by the sensor and each service system is analyzed and mined, an analysis result is dynamically formed, and a scientific basis is provided for diagnosis of the running state and auxiliary decision of safety management of the gas pipe network.
According to the gas pipeline safety monitoring system provided by the embodiment of the invention, the collected and fed-back information is analyzed and mined based on the GIS platform, a visual analysis result is dynamically formed, and the efficiency and the intuition of safety monitoring are improved.

In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof.
