Expressway Management System

With the fast development of the computer and communication technology, the information technology has already got deeply to the society each aspect. The administrative department of highway of our province has successively introduced the Computer Pave Management System (CPMS ) and Computer Bridge Management System (CBMS ),it has changed the management level of the highway department greatly and has settled solid foundation for implementing scientific maintenance decision . On the basis of popularizing and applying CBMS and CPMS, utilize the information manage technology , to strengthen the development and use of the information resources of the highway, study and popularize the highway database of practicability, and apply to the maintenance and management of the highway actually, realize the great-leap-forward development of information management of the highway. Afforest management is one of important content to the maintenance, afforest management of expressway can use three impose, seven maintenance to describe, the result not only depends on designs and plant, but also depend on the later maintain. Maintain and management is important to reflect expressway management level and have incomparable function. According to ? Shandong expressway afforest management method ?, it make for afforest rule that design and operation of our province expressway. It rely on dizzy and lead function of the main fact in the central, distance side afforests and takes water to make soil conservation, firm slope as the core, choose resist drought, resist pollution, resist plant of plant diseases and insect pests, to establish a "four season evergreen and three season have follower all the year, color abundant succinct and lucid lively" to the highway environment.At present, the expressway afforests file relies mainly on writing down, dispersing the mode of management. Seeing that afforest management style and means, it can't meet the requirement of growing information management, in order to improve expressway afforest efficiency of management, craft management numerous and complicated way of datum these meet the trends of the times yet, realize afforest management by the computer control of the standardization and automation of the data, afforest management and move towards the modernized inexorable trend.Afforest management including various kinds of vegetation water, prune, weed, apply fertilizer and organic to transform, loosen the soil, prevent and cure plant diseases and insect pests, set up the nursery while being fat soil regularly, transplant, mend and plant etc. Afforest management pieces of more,line long, pieces of wide and scattered characteristic to expressway, in order to enable leader to understand the distribution situation of every kind of vegetation of the whole expressway in time, combine expressway afforest actual conditions of management, we order the line sequence model. To carry on demand analyse at first, make the concrete requirement to the function of the software, recommend systematic design and how to realize then. This system is developed on Powerbuilder8. 0, the database is Sybase SQL Anywhere. It describe the PowerBuilder how to join database in detail, proving every form that use carry on definition and comments , data structure to system at the same time, then maintain in order to afforest the afforestation current situation data under the data menu - the threads and statistical report as examples, it explains the afforests management system to realize the concretly course.Finally summarized the system brought the advantage to afforest management and improve method. This system is made up by file, afforest data, system maintain, data management , data transmission and helping etc. Through this system, it overcome artificial statistics calculate tedious, consuming long time, real-time character strong consulting, defecting such as being inconvenient. When the basic data changes, every management office reports the basic data to the company, the company can inquire to the newest data appearing in time. The leader can understand the distribution situation of every kind of vegetation of the whole expressway in time, it can understand every management office every mileage, segment, variety, specification, block name, quantity, etc.The pieces of distribution situation of vegetation, even understand that afforests the overview , suitable for managing and protecting the situation and soil distribution situation of the nursery stock, vegetation planted in every area under one' s jurisdiction, offer aid decision support for afforest management in the expressway.
