Description
Technical Field
The invention relates to the technical field of hydrology, water quality and meteorological monitoring, in particular to a multifunctional integrated intelligent hydrology pole.
Background
Under the big background of the strong national strategy of the network and the water control policy of 'water saving priority, space balance, system management and two-hand force application', along with the rapid promotion of the construction of the intelligent society, the requirements of water conservancy informatization and intellectualization are more and more strong. The water conservancy information is used for driving water conservancy modernization in a water conservancy informatization mode, a safe and practical and intelligent efficient water conservancy information large system is built, an integrated monitoring sensing system covering river water systems, water conservancy projects and water conservancy management activities is built, the construction of a water conservancy large data center is promoted, and the water conservancy large data analysis and processing capacity and the sharing service level are comprehensively improved.
However, through full research and analysis, the applicant still has the following development pain points in the intelligent water conservancy industry at present:
and a hydrological monitoring integrated device which is cheaper, more flexible and more suitable for large-scale distribution is lacked. The traditional hydrological monitoring station is not suitable for large-area and large-batch construction due to the limitations of construction capital cost, construction time cost, post-construction management cost and operation and maintenance cost. However, comprehensive perception can play an important role in overall analysis and decision making, and therefore, the need for comprehensive perception of the whole watershed and even the whole country is more and more urgent. Although the traditional monitoring station has the advantages of high precision, accurate data and the like, new product ideas are still needed to meet the requirement of comprehensive perception.
There is a lack of integrated devices for multiple business scenarios. In a water conservancy business scene, different business departments can usually develop different application systems aiming at different business applications, and each system has data acquisition-storage-application and forms a closed loop, so that the data island phenomenon is serious, and a chimney system stands; in addition, because different system construction parties are different, even if data interconnection and intercommunication and mutual sharing are realized through an interface, the negotiation and communication costs are high, and therefore the data are difficult to utilize mutually; finally, even different business departments inside the water conservancy department can hardly grasp whether the data required by the business departments are collected by other departments in time. For example, in the river growth business, video/image monitoring and early warning are required for river floating objects, garbage, pollutants and shore illegal buildings, and video monitoring and early warning are also required for sand collecting ships and sand collecting behaviors in the water administration law enforcement business. Therefore, most of the time, the video cameras meeting the service requirements can be shared, and only the monitoring emphasis of the two services is different. However, an integrated device capable of simultaneously meeting the video monitoring and early warning of the two or even multiple services is still lacking at present.
An integrated device with a unified interface standard and a unified storage standard is lacked. The access standards of monitoring devices of different manufacturers are different, and the storage standards of monitoring devices built in different cities are different. Access standards are different, for example, if a water level meter, a flow meter and a video camera of the same hydrological monitoring site are not produced by a manufacturer, the water level meter, the flow meter and the video camera all have own client terminals to receive collected data, and although the collected data are finally forwarded to the same platform for processing, displaying and analyzing, the transferring process is complex and the data at the moment are not source data; the data collected by the equipment built by water service bureaus of different cities are difficult to be collected into a uniform resource pool due to different storage standards, for example, the data collected by the equipment built by water service bureaus of different cities is difficult to be collected into a uniform resource pool not only because the different cities lack a platform for uniformly collecting the data, but also because the storage and calling standards are not uniform, so that the difficulty in calling the data into the uniform platform for data governance is high. If the equipment of each monitoring site is collected uniformly, and simultaneously, the collected source data are uniformly stored in the same resource pool, the application of the data in the later period is more standard and more comprehensive, and the method is also favorable for one source and avoids repeated construction.
An integrated device with intelligent monitoring is lacking. The edge-center cooperative processing analysis is an effective mechanism for reducing the central computing pressure and slowing down the network transmission load. Data collected by the monitoring equipment are subjected to preliminary analysis and processing on the edge side through the edge calculation module, and after compression and arrangement, results are transmitted to the center side for further analysis, processing and display.
The problems are increasingly prominent along with the continuous development of water conservancy informatization, and the exertion of the whole benefits of the water conservancy informatization is seriously influenced. Therefore, the conversion from the power-assisted digital water conservancy to the intelligent water conservancy of an innovative integrated monitoring device needs to be explored and developed.

While certain exemplary embodiments of the present invention have been described above by way of illustration, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and are not to be construed as limiting the scope of the invention.
