[0030] The inspection and maintenance function module provides management services for the inspection plan of the bridge. The inspection part includes sub-modules such as my plan, schedule, project plan, and meeting management, and can assist in the completion of the inspection form template. It qualifies the diseases encountered during the inspection process and provides the corresponding maintenance measures for the managers, and can be automatically linked to the required maintenance costs. In this system, we have specially set up a measure library to serve this module.
[0031] The bridge condition assessment module is mainly responsible for checking the current condition assessment of the bridge, and using the Markov chain and other algorithms frequently used in the bridge industry to work together to calculate the future condition to realize the prediction of the future condition.
[0032] The information query and report report function module is used to query the bridge status and daily work with different query conditions according to the requirements of the manager and can independently customize the required statistical information to generate corresponding charts and reports. The reports can be passed by the administrator The will to choose the type.
[0033] In bridge information management, there are multiple data formats, and these data include spatial data, attribute data, and bridge management data. The amount of data is huge. In a sense, data is the basis and guarantee for the operation of the bridge information management system, reflecting the practical value of an information management system. The system adopts B/S architecture, which can well meet the requirements of bridge management for geographic information systems such as GIS, and make the system open and easy to expand. He divides the task into two parts: server-side and browser-side. The client can request data, analysis tools or modules from the server through the browser. The server executes the client's request and sends the results back to the client via the network, or sends data and analysis tools. Sent to the client for client use. Because WEB GIS applies the concept of B/S to perform GIS analysis tasks, it realizes the characteristics of high efficiency, operability, flexibility, timeliness, safety, fault tolerance, confidentiality, and scalability.
[0034] When the user manages the target bridge. The corresponding geographic information of the target bridge can be located on the geographic information map to locate the target bridge. The GIS map is equipped with an information management interface for all bridges in the area. If the user needs to manage the target bridge information, just use the GIS map Select according to the corresponding geographic information of the bridge or locate on the map through the target coordinates to switch to all the required management functions of the target, which greatly improves the convenience, accuracy and intuitiveness of finding and positioning the required management bridge, and realizes geographic The information map and the bridge information management function complement each other.
[0035] The system server is divided into WEB server, file server and DB server according to the system requirements. Whether the hardware can be separated or not can be determined according to the actual deployment needs. In the case of low load, the three can be deployed on the same server. The current database management system not only can manage the attribute data, but also the integrated management of graphic data and attribute data, especially the highly integrated integrated management of graphics, attributes, images, texts, etc., has been relatively complete.
