Description

Technical Field

[0001] The invention belongs to the technical field of emergency command, and in particular relates to a rainstorm emergency rescue and dispatch command system for bridge construction. Background Art

[0002] During the construction process, the safe operation of the system has a significant impact on the investment, management, and safety of personnel and equipment of the project. Among them, heavy rain has an impact on the safe operation of the construction. Therefore, it is very important to conduct emergency rescue and dispatch command for heavy rain during construction.

[0003] A general rescue system, such as a construction period flood control emergency system disclosed in Chinese patent CN110541389A, includes: a basic data collection module: used to collect basic data required for flood control calculations, including rainstorm and flood data, design flood results, engineering characteristics, and diversion plans; a flood control calculation module: used to calculate the diversion flow of the upstream reservoir based on basic data; a flood impact analysis module: used for real-time flow calculation, water level calculation before the weir, backwater calculation, weir breach calculation, and power calculation; a small watershed rainstorm and flood warning module: used for rainstorm warning and flood warning; a decision support and warning module: used for the release and query of warning information. This improves the accuracy of flood risk detection, warning, and estimation of loss after an accident for cofferdams, as well as emergency decision-making in response to accidents.

[0004] However, in the above scheme, it can only collect the parameter of flood water level rise and calculate the event or probability of rainstorm accidents. The collected data is small and the prediction accuracy is low. Therefore, a bridge construction rainstorm emergency rescue and dispatch command system that can collect and analyze multiple data and has high prediction accuracy is needed. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a bridge construction rainstorm emergency rescue and dispatch command system, which has the characteristics of being able to collect and analyze a variety of data and having high prediction accuracy.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A rainstorm emergency rescue and dispatch command system for bridge construction includes a perception layer, a transmission layer, a processing layer and an application layer.

This ensures that the urgency of issuing an alarm and the severity of measures match the actual construction environment, thereby improving the pertinence of the alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0017] Figure 1 It is a structural schematic diagram of the present invention; DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1 ,A bridge construction rainstorm emergency rescue and dispatch command system includes a perception layer, a transmission layer, a processing layer and an application layer;

[0020] Among them, the perception layer is used to obtain relevant information during the bridge construction process, including rainfall information, precipitation water level information, meteorological information, on-site construction information, and construction equipment location information;

[0021] The transport layer is used for data transmission, transferring information from the perception layer to the processing layer;

[0022] The processing layer is used to analyze and process the data transmitted by the transport layer and transmit the processed data to the application layer;

[0023] The application layer is used for data display and dispatch command information release;

[0024] When in use, the perception layer obtains rainfall information, precipitation water level information, meteorological information, on-site construction progress information and construction equipment location information during the bridge construction process, and uploads it to the transmission layer. The transmission layer transmits the above information to the processing layer using wired or wireless communication protocols. After receiving the information from the transmission layer, the processing layer analyzes and processes the data, determines the accident risk and the measures that need to be taken, and sends the accident risk and the measures that need to be taken to the application layer. The application layer is used for data display and dispatch command information release;

[0025] When the processing layer obtains some information, it divides the information into two categories;

[0026] The first is environmental information, including rainfall information, precipitation water level information and meteorological information. These three types of information are quantified into the size of precipitation and flood risk. The greater the precipitation or flood risk, the more urgent the need to issue an alert and the stricter the measures.

[0027] The second is construction site information, including construction progress information and construction equipment location information. These two types of information are quantified as project progress. When the project progress is closer to the middle of the full progress, the urgency of issuing an alarm and the strictness of the measures will be higher. When it is closer to the two ends of the full progress, the urgency of issuing an alarm and the strictness of the measures will be lower.

[0028] As the project approaches the middle stage, the structural strength of the construction is not enough to withstand large floods or rainstorms. In addition, there are many types of construction equipment on the construction site, the environment is more complex, and the risk resistance is weaker. Therefore, the urgency of issuing alarms and the strictness of measures need to be higher.

[0029] When the project is at the beginning stage, the more complex structure has not yet been built, there are fewer construction equipment on site, the environment is relatively simple, and the ability to resist risks is stronger. When the project is at the end stage, the structure under construction is basically completed, the structural strength is strong, and some equipment on site has been withdrawn in advance, the environment is relatively simple, and the ability to resist risks is stronger. Therefore, the urgency of issuing an alarm and the strictness of the measures are lower;

[0030] By setting up a perception layer and enabling the perception layer to simultaneously obtain rainfall information, precipitation water level information, meteorological information, on-site construction progress information and construction equipment location, the processing layer can comprehensively judge the urgency of issuing an alarm and the strictness of measures based on several types of data divided into environmental information and construction site information. It can collect and analyze multiple data and has a high prediction accuracy.

[0031] At the same time, by displaying the greater the precipitation or flood risk based on rainfall information, precipitation water level information and meteorological information, the urgency of issuing alarms and the strictness of measures will be increased, and the construction work progress information and construction equipment location information will be quantified as project progress. The closer the project progress is to the middle of the full progress, the higher the urgency of issuing alarms and the strictness of measures will be, and the closer to the two ends of the full progress, the lower the urgency of issuing alarms and the strictness of measures will be. This ensures that the urgency of issuing alarms and the strictness of measures match the actual construction environment, thereby improving the pertinence of alarms.

[0032] As for the perception layer, specifically, the perception layer includes rainfall monitoring sensors, water level monitoring sensors, meteorological information collectors and video surveillance cameras. The rainfall monitoring sensors are used to monitor rainfall in real time. The water level monitoring sensors are used to be installed in the bridge construction area and its surroundings to monitor the precipitation water level information in real time. The meteorological information collectors are used to collect temperature, humidity and wind speed meteorological data. The video surveillance cameras are used to monitor the construction area in real time. The construction equipment status monitoring sensors are used to monitor the operating status of the construction equipment.

[0033] Video surveillance cameras are used to take pictures of all aspects of the construction site;

[0034] When each piece of construction equipment enters the construction site, an operation sensor is installed and the operation sensor is communicated with the construction equipment status monitoring sensor. The operation sensor is used to monitor the orientation and opening and closing of the equipment. The construction equipment status monitoring sensor determines how many construction equipment are in the current construction scene and the construction equipment that is in the startup state by collecting data from each operation sensor.

[0035] For the transmission layer, specifically, the transmission layer includes a wireless network transmission module and a wired network transmission module. The wireless network transmission module is used to wirelessly transmit data from the perception layer to the processing layer through 4G / 5G, Wi-Fi and LoRa wireless communication modules. The wired network transmission module includes a data transmission line and a receiving port. The wired network transmission module is used as a backup transmission means.

[0036] By setting up a wireless network transmission module and a wired network transmission module, the two sets of modules can back up each other, reducing communication obstacles when one set is damaged.

[0037] For the processing layer, specifically, the processing layer includes a data processing module and an early warning analysis module. The data processing module is used to clean, integrate and analyze the collected data and upload it to the early warning analysis module. The early warning analysis module is used to analyze the development trend of heavy rain based on real-time data and historical data and upload it to the application layer.

[0038] Specifically, when the data processing module receives environmental information, it arranges several environmental information received in the past in chronological order, cleans data that are too far away from the linear regression according to the result of linear regression, and fills in missing data according to the result of linear regression;

[0039] Subsequently, the data processing module uses the ARIMA algorithm to calculate simulation results based on several environmental information received in the past, and judge the future trend of environmental information. When the trend shows that the precipitation or flood risk exceeds the threshold, the data processing module sends the corresponding judgment to the application layer;

[0040] At the same time, the data processing module is pre-input with the imagined pictures of the completion status of the construction structure at different stages in the arrangement orientation of each video surveillance camera. When receiving the picture from the video surveillance camera, the received picture is compared with the imagined picture of the corresponding video surveillance camera angle, and the picture that is closest to the imagined picture of the completion status at a certain stage is found to determine which stage the project is in.

[0041] As for the application layer, specifically, the application layer includes an early warning release module, which releases early warning information to construction personnel and relevant departments through various channels such as SMS, WeChat, and broadcasting;

[0042] Optionally, the application layer also includes a decision support module. The decision support module inputs several plans, including disaster risk assessment, rescue plan assessment, etc. Each plan corresponds to different precipitation, flood risk, completion status and equipment distribution. When the application layer receives information from the data processing module, it generates decision recommendation information to provide emergency decision support for managers.

[0043] In order to facilitate operators to collect information about the data collection, processing and distribution process more comprehensively, an information display platform is also included, and the information display platform is connected to the application layer in communication;

[0044] In this embodiment, the information display platform integrates GIS maps to display the early warning information, decision-making recommendation information and dispatch command information output by the application layer, and simultaneously displays the rainfall monitoring information, water level detection information, meteorological information, video information and construction equipment status information output by the perception layer.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
