| According to its rapid development in recent years, the computer has developed very fast into greater capability with the price getting lower and lower. The extended application has achieved far more than calculated. It has infiltrated into all the areas of social activities and has widely been used in the field of road transportation systems.The highway toll collection system is generally composed of two main parts: the computing toll collection system and the visual supervision system. From the way of operating it can be divided into the open toll collection system and the close toll collection system, and from the way of toll collection, the semi-auto way and the auto way. On the basis of late-started road systems in China, most roads depend on the open semi-auto system. In the fact of nation's constructing roads, the main task of toll collection is to repay the loans. In practice the software is required to be adapted to all the differences in the toll collection rates and categories, for the different classes of roads and automobiles with different rates of toll collection and the corresponding deductions. Meanwhile, the software is also required to have the correspond changes at the warnings of sound and light to prevent the disadvantages of handcraft toll collection. With the technical purposes of pictures, sounds and outer control of the equipments fully used, the clear pictures need to be both animated and static, characters-spliced and qualification standards met. The toll collection system needs to be equipped with warning devices, passage lights and the barrier controllers so as to guide the automobiles to pass. In all, this system is needed to own the functions of not only outer controlling but also the data collecting and analyzing with the final agreement report produced to the toll collection.The Highway Toll Collection system has come into being used over ten years. The monitoring system is basically used very well and the key factor is the equipment 's shaping and quality of constructing. The core of this technique exists in the lane control of the highway toll collection system. The Lane control system is from the compile language to the visual language, from the data storage, the small database to the present large database. The whole program is from the handcraft ways to the quality-controlled project techniques, from the parking toll collection to the semi-auto toll collection , is complied with the newest road building perception and the updated monitor techniques of the computer. The lane control system in the toll collection system is possible to be frequently implemented according to the user's needs and amplify the module.In this over ten years,I have made my best to the study of lane control.I saw the initial weakness,such as the difficulty of line connection,the unsafety of vehicle count,the unflexible control of peripheral equipments,etc.I solve these questions one by one.In the realistic application, it has been used on the assembled cars' classification and the untouched IC card technique (being used in the administration of communication tickets and the freeway's closed entry and exit toll collection), the whole toll collection system not only takes effects in the highway toll collection system but also, through the minimum changes, shows its prospective in the building automatics, parking lots, business nets, public supervisions and many other lines of monitoring and toll collection. What we have acquired are as below: The computer of LCM-2 model, which is used to control the carriageway, has been confirmed as the provincial and city's science technique research. GLS-2 highway toll collection system has gained the praise from the science advancement from Liaoning province and Dandong government. DG4 automatic hit-resistance bar has gained the praise from the science technique and the research results of Dandong city government.4. LuFeng highway toll collection system has acquired the praise of being an excellent software product from Liaoni...
