ARM-based Intelligent Locker Design For Coal Mines

With the rapid development of information technology and deepening understanding of human. What to be solved personal privacy issues has became increasingly prominent,and the protection of personal privacy issue has become the focus of the problem.Nowadays, Our country also introduced a corresponding policy that raised in the Report of the Eighteenth National Congress of the Communist Party of China, which is the strong evidence to promote social harmony and to maintain social fairness and justice. Embedded System applications has many advantages, and its use to achieve access control has become a hot spot in recent years. Because of its stable performance, good development environment and other advantages, the design selected the Embedded Applications as the main control system, while allowing subsequent development, and provide a good hardware support for future extensions.In this paper, we choice the Embedded Technology to achieve the design of the intelligent lockers. Firstly,I introduced the significance and feasibility analysis of this topic.Secondly, took a thorough discussion to the radio frequency technology in non-contact IC card Access Control System.Then,list the corresponding in-depth discussions and detailed knowledge of the ARM Embedded Systems as well as the corresponding main control chip S3C2440 on-chip resources. Finally, build a hardware platform with the implant, and gives a systematic presentation to the other aspects of the software platform, which can basically achieve the pre-access articles as well as through the PC on the lockers open and closed real-time monitoring features, while the power supply to achieve by means of embedded lamp charging function.The real solution to the problem of the miners in mind,and reached a preliminary concept design. The design works by using the Access Controller to contect the Entrance Guard Connection Identifier. Mainwhile, to achieve the purpose of the appropriate information transmission the Access Controller and the main controller ARM S3C2440 were used 485 converter to connect each other. The main controller can also be carried out with the PC serial data transmission to get the real-time monitoring and scheduling. When the miner workers commuting punch on read access identification card information, the corresponding locker is opened and closed.While the operating information is uploaded to the host controller and the PC for storage.Thus can easy to follow real-time monitoring and query; Once the miners forget the card or the card lost the corresponding information,the staff on duty can use pre-set password to open the terminal cabinet; The design of embedded corresponding power module can charging worker's Miners. While we can extend primary controller interface to manage the lamp charging.Through a simple test and evaluation, the system basically to achieved the pre-conceived function.The design includes access control unit, the main controller module and the host machine. Access control unit through access miner to read out the information of the worker's card and transmit it to the access controller.The corresponding electromagnetic locker open and close. Then use the 485 converter to transfer information to the main control module.The main control module transmit information to the host computer.The information can be stored and displayed in the access control software. Thus can achieve real-time information transmission.The design of the corresponding functions to meet the needs of miners' privary.While its reserved the corresponding extension modules,which can lay a solid foundation for further development.At the same time, due to author is non-design professionals, the design is to be implemented on the function. I can't get out the overall design of Intelligent Lockers.So I should take into a wide range of knowledge in the subsequent studies and achieve it.
