1. Introduction

The project construction management institution is facing many quality supervision problems because of highway construction having the features of many points, long length and wide range. During the construction of large highway, the construction management institution is far way from the construction unit and the supervision unit; also, poor information exchanged between the units. Thus, it is easy to cause management problems and low efficiency. If the construction institution does the site inspection check as the traditional way, it is time-consuming and expensive to master the site conditions. Construction resources change frequently. Therefore, it has strong dynamic and a wide range of management. It cannot achieve seamless supervision of the raw material transport vehicle routes and the retention time; so, it is easy to appear the phenomenon of shoddy. In the mixing stations, many artificial factors affect the production mixture ratio; as a result, it cannot be guaranteed that the quality fluctuations are completely under control. Besides, thanks to the degree of modernization for the site construction control means is low and subjective factors have great impact on monitoring measures, the construction quality cannot be effectively ensured.

With multimedia and information technology developing rapidly and the popularization application in social sectors, human society has been promoting into a Being Digital, high-speed information age in the past ten years. In the traffic engineering construction field, it has completed the transition from the previous document submitting, auditing, releasing, circulation and other office automation to a dynamic management information illustrated platform which reflects the quality control. The increasing demand for the hardware equipment such as network cameras is due to the platform for project providing a friendly human-machine interface, professional business design and giving full play to the role of media and information technology. It greatly reduces the cost of the project management and improves the management efficiency.

The writer developed a dynamic management platform of the highway quality manage relying on the construction of a highway in Shandong Province in order to strengthen the on-site quality supervision, realize the specialization, standardization, elaboration and informatization through the modern information technology and effectively implement the requirements of the Ministry of Transport and the Shandong Provincial Communications Department. The writer aims to implement the project management concepts and ideas, reduce management costs, improve management efficiency and realize the project quality management to be dynamically and intelligently controlled by the modern information technology.

1.1. The market demand analysis

The Fifth Plenary Session of Communist Party of China's Seventeenth Party makes a scientific conclusion for the next period of economic and social development of China's domestic situation. The Twelfth Five-Year Plan period is not only the key period to build a moderately prosperous society, but also the key period to deepen the reform and opening up and the crucial period to accelerate the transformation of the model of economic development. China's economy and society are still in the period of seizing a great deal of important strategic opportunities. The conclusion is a very important strategic judgment and a great significance to profoundly understand the situation of the transport development, promote the scientific development of transport, implement the Moderate Advance in Accordance with the Principle of Coordinating the Development of Various Modes of Transport principle, and maintain an appropriate scale and speed of construction for the transport infrastructures. Besides, it accelerates the optimization of the overall structure of network upgrades, and improves service levels further.

In the aspects of the dynamic management of the construction quality, at present, some domestic project's mixing stations or key project construction sites use the video monitoring technology, that is,

through the on-site video surveillance, to remotely access to on-site construction progress. Some project uses the automated real-time monitoring technology in cement concrete mixing stations and the GPRS wireless transmission technology, which is, through the real-time mixing stations production data acquisition and wireless transmission, to remotely access to production status of mixing stations. However, it is still a blank for the internal quality control for the project or key part of the overall process, such as raw material transportation, mixture mixing production, construction mixture ratio, material transfer vehicle passing in and out mixing stations for identification and weighing, road paving, RCC and other data collection, the mathematical statistics and analysis in order to achieve modernization information technology and engineering construction control technology; especially the concept of domestic construction specifications and project management. As a result, the dynamic intelligent management of the project construction process quality will become a new trend. The use of modern information technology not only promotes technological innovation, but also strengthens the information technology development in the highway construction. It meets the growing market demands, and has broad market prospects.
