The Set Research And Application-controlled Unlocking Key Management System

Currently, five anti substation computer system to unlock the key management is still in a relatively early stage, backward management, there are many problems, such as registration and approval system is not rigorous, it is difficult to monitor the implementation, unlock key is running, operation and maintenance personnel are free to hold, unlock phenomenon often arbitrarily, for all kinds of vicious misuse accident occurred planted security risk. Therefore, an urgent need to use more advanced computer and communications technology to solve for the unlock operation to achieve efficient management.The research and development project set-controlled unlocking key management system to unlock the key management system as the main object of study can be divided into the unlock key to unlock the key management system and management information systems of two parts. Unlock the key management machine part, the main use of ARM embedded technology, based on Ethernet and GSM short message communication technologies, as well as Ir DA infrared detection photoelectric sensor, electromagnetic control technology, infrared dynamic monitoring and RFID contactless radio frequency technology and other advanced technology, while using ARM programming language design. Unlock key management information system using C / S architecture,application development using c # language and SQL Sever databases in conjunction.The use of set-controlled unlocking key management systems, real-time data can be collected to unlock the key management machine to collect the keys to unlock the use of state, once substation on duty through the system to unlock the key to the application,the system sends a message to the personnel system to unlock the key to the use of qualified approval personnel, including network computer(the computer network) and SMS, with the approval or qualification prescribed form reply via SMS, the system information to confirm the approval, as approved, then open the Control key management machine to unlock the door, allowed to run duty using the unlock key;otherwise, no key to unlock any operation manager.Set-controlled unlocking key management systems use, can contribute to operational duty substation in strict accordance with the requirements of the process to unlock the key to the use of the application, with the keys to unlock the use of qualifiedpersonnel vetting convenient for approval. Meanwhile, the system can use the key to unlock the real time recording and retrieval, unlock the key management becomes more efficient and convenient. But also greatly improve the security of the unlocking operation, reducing the investment cost of labor management.
