NFC-based Electronic Patrol System Design And Implementation

Currently, in everyday life everywhere community patrol officers to specific areas regular or irregular inspections of safety management. Including pre-Qin instructed, will sign a point, set up card inventory, etc., the service work by himself manually fill in the log of the duty, and the operating point of the dispersion is not conducive to unified supervision, there is a lack of means of information, service information acquisition, enter the complex regulatory information is not real-time feedback, service conditions and other issues is not clear.To solve the timeliness and convenience of the problems of the conventional technology can not both of the electronic patrol, the subject of design and implementation of a NFC-based electronic patrol system, change the existing "manual staff attendance, leadership random checks," the traditional patrol management, assessment mechanism. Use a wide coverage of mobile terminals and NFC tag technology, equipment and patrol ban special card, simplifying management, and strengthen the quality of management, improve resource utilization.This paper use Android Terminal NFC technology and mobile communications technology, the connection between the mobile terminal and NFC tags and NFC tag reading and writing capabilities, and uses base64 encryption algorithm to encrypt the information in the label. First, define the subject NFC tag NDEF data exchange format, NFC tag and mobile terminals connected through the RF field, and writes each label in accordance with the format Patrol point information to achieve interactive communication NFC devices and NFC tags. Secondly, when the mobile terminal touch the NFC tag, the mobile terminal automatically detects whether its own NFC-enabled and is turned on, and information gathering patrol, select the appropriate treatment Activity tab pop up window displays the location of patrol for user interaction component. Finally, the use of XML as a data exchange method using mobile communication technology will patrol the background information in real time to upload to the Web, is stored in a MySQL database. Electronic patrol work to achieve the information, intelligence, has some practical value.
