The highway construction project is complex, more documentation, large data volume, especially measurement payment and change processing business model, complicated, computational amount, more and complicated.
With the continuous expansion and improvement of construction scale and construction requirements, the requirements for the management level of various participants in highways are also increasing. As the owners of the direct person in charge of the construction project, the duties of general command, general coordination, total management, the strength of the management capability, and the efficiency of its management capabilities are directly related to the construction of highway construction projects. Engineering progress and management efficiency.
However, the current management methods and methods of each participant are still continuing traditional manual management models. In the face of new forms, traditional manual management models have become increasingly difficult to give full play to complexity requirements for the ability and management of existing human resources. Therefore, urgent need to use new methods, new management models, new technical means to solve a system problem facing highway construction management under the new situation.
To this end, Bohen has developed a highway construction project (owner) management system to help owners establish a complete management system, optimize the management process, and conduct whole process management of highway construction projects; timely acquisition of data generated during construction, Realize the centralized unified share of data, realize the cooperation between owners and participating units and timely communication; standardized management of a large number of documents generated in the construction process; solve the most complicated issues such as measurement payment, change management and reporting; Make the owner to make timely dynamic and control of engineering progress, quality and investment. solution
system introduction
"Born Expressway Construction Project (Owners) Management System" is to meet the specific business process requirements of the owners' road project management, and the main participants in the construction of highway projects: owners, supervision, contractors, owners A integrated software system that assists in highway construction project management.
The system covers the whole process management of highway engineering projects and the corresponding document management, including project progress, construction fees, interviews, contract management, etc., can handle road construction, initial, construction drawing design, bidding management , Contract change, measurement payment, data summary examination and approval, report printing, various queries, completed data management, budget and final accounts, etc. The various major functional modules of this system cover the whole process, convenient and efficient road construction cycle, and to achieve integrated application of highway construction management.
The system focuses on "investment control" in highway construction project management. Understand the management of road construction projects with important activities in engineering management, contractual project management, and project construction process - metrology, payment, change, etc. The system needs to cross the local area network of the user unit and the Internet, thereby reach the synergy between various departments, unified management, and centralized processing between each department. To this end, the system adopts the currently popular B / S architecture.
This product is closely surrounded by the construction of the "three major controls, two management" goals, combined with office automation, schedule, information property management, using today's popular object-oriented software development methods, and constructing advanced information management tools, better implementation. Information management integrity and clear trace management. Greatly improve road project management level, reduce management costs, and make judgments for decision makers to provide important information basis.
System functions
The system is divided into two major parts of the front desk and the background system. Among them, the front desk is implemented, and the auxiliary user reaches its predetermined business goals, and is part of the use of ordinary operators for ordinary operators, and the main part of the system. The background system is provided to the user-based system administrator, maintaining the basic data maintenance of the system, such as the settings of user rights, use the department of the front desk system and the determination of the position, the user type division, etc., to ensure the normal system safe operation.

Architecture
The system uses a C / S, a B / S hybrid architecture. The overall system is divided into two major parts of the front desk system and the background system. The front desk system is the body of the entire software system, but also the user's functional demand, complete user service processing, and reaches the part of the user service target. This system uses a B / S architecture that allows the rights-controlled users to complete their rights tasks through the Internet / Intranet and system. This system mainly uses ASP.NET technology to build and implement. The background system uses the system's auxiliary support system to configure the basic parameters and setting items for the normal operation of the system, and the system administrator controls the functional interface of the entire software system. This system uses a C / S architecture, running in the LAN of the owner, through the .NET Remote technology, implement the front-end interface and the system database, and store various types of configuration and setup information into the system database, for the system Normal operation is guaranteed.
The entire system across the owners and two network spaces, collects data from multiple information generated, and is unified to process and save.
The system hierarchical block diagram is as follows:
The system is logically divided into multiple layers. Indicates that there are two categories, one is the interface of the Windows Form type used by the background system user, and the other is the web interface used by the front desk user. System function implementation is divided into three parts: BFL (business appearance layer), DAL (Data Access Layer), CommON (General Layer).
BFL (Business Appearance Layer) provides the implementation of each specific business logic, closes the user service algorithm and processing flow. The purpose of each business process is independent.
DAL (Data Access Layer), using ADO.NET technology, package database access logic and partial database control logic (partial database control logic is implemented in the database system through the storage process). The system business logic processing is separated from the specific database to achieve the purpose of the business and database access.
Common. Contains "global common variables" similar to the traditional programming method, other layers, including BFL, DAL, etc.) are visible to the logical subsystems of each part. The implementation of public classes and common methods that may be used in each layer, unrelated to specific business processing logic and specific data logic. (Such as all kinds of substrs inspection functions, encryption decryption functions, etc.)
Backstage
The background system uses Windows Form how, .NET Remote Remote Access Technology, C / S architecture access system database. The system administrator of the owner, sets and saves system basic information in the database (such as username, user privilege, system function).
Front desk
The front system uses the browser interface, ASP.NET technology, and the B / S architecture. The system user enters the system through the Internet / Intranet, accepts system services, accepts system services, and performs the operation and processing of service functions, and completes the operation and processing of business functions. The front system involves the operation and control of multi-party users and the type of type, and completes various role users' business operations based on the settings of the system administrator. feature design
The background management system of the high-end project is based on the analysis and research of the high-speck program's background management system. Refers to its system structure, module division, and combined with the high-time division project business, it is reforming. During the reconstruction process, the functional division of the background system basically follows the division of the high-projection project, but the system architecture is redesigned and set up.
The background system uses a C / S structure. The system function is implemented in the client. The client is directly connected to the system database through the network, saving the setting operation of the client system administrator.
According to the business needs, according to the function is divided into 7 functional modules:
1. Subsystem structure 2. Organizations 3. Basic data 4. User management 5. Customized table 6. Template settings 7. Help
Subsystem division, organization, basic data, user management, template setting service classes to implement business public interface (IbusinessClass), using common subforms (Subform), display (form of each function module) Separately display the user interface. Contract rights operations are different from other functional modules due to business processing processes, so they do not implement business utility interfaces.
