Use CC2530 and MF RC522 to build a wireless RFID reader, build slaughter traceability system software on the Visual Studio 2008 platform. System integration tests showed that the use of ZigBee wireless transmission technology can transmit data with two-way so that the reader system applications more flexible. The system of pig slaughter traceability has high stability of the system, identify the long distance, scalable and improve the pig slaughtering traceability management efficiency. At the same time, the traceability system has a certain reference value applications in the study of domestic food safety issues. It's useful for improving the level of China's food industry information.Keywords-Traceable system; ZigBee; RFID reader; CC2530; MF RC522I. I NTRODUCTIONIn recent years, the production of livestock appears steady and healthy development However, during the process of pork production, not-standardized corporate governance and product safety issues trigger animal food safety incidents occurs[1]. Therefore, building a perfect traceability monitoring platform is useful to guarantee food security, improve the economy and living standards. Currently, the food traceability generally use RFID radio frequency electronic identification. Since the existing RFID reader is generally based on the cable transmission, there are disadvantages of fixed position reader, poor flexibility, short-distance transmission and high equipment costs. Comparing with cable transmission system , using zigbee wireless transmission technology can achieve two-way wireless data transmission, the reader system applications are more flexible.At present, China's animal product traceability system based on the theory and practice made significant progress and breakthroughs, and applied to product traceability.Wang PeiQiang , etc. analyze and design pork traceabilitymanagement system based on RFID and bar codetechnology[2], and develop a workable traceability codingrules, associated with the entire logistics chain. But thereis no detailed study and design for hardware systemsproduct traceability and traceability information collectedinformation. Bao Xiao Cheng, etc. theoretically analyze traceability of pork products, key factors and traceabilityinformation systembut[3], but did not realize the systemand applied to actual production traceability process.In this article, we design a portable wireless RFIDreader by intergerating ZigBee wireless communicationtechnology and RFID technology. This will make up for the shortcomings of traditional RFID, and it’s useful toimprove real-time monitoring and network slaughterhousewith the use of ZigBee wireless network technology.Based on C/S we develop traceability system applicationsoftware on the Visual Studio 2008 platform, and recordinformation of pig slaughter, quarantine and split intothe segmentation database center through a wireless RFIDreader to achieve production information management; Meanwhile, information inquiry terminal provides information services for enterprise manageent, and managers can query the corporate information, employee information and product information through the terminal.II. S YSTEM A RCHITECTUREA.System DesignSlaughter traceability system consists of a wirelessRFID reader, ZigBee wireless sensor networks and C / S application software developed on the Visual Studio 2008 development platform. Based on the production process of meat processing factory in Lanzhou, consider HACCP system as theoretical basis [4], combining with the actual production process, to determine the function of the system. With this traceability system record the information of production process into the database, achieve inqury and management of the enterprise andInternational Conference on Logistics Engineering, Management and Computer Science (LEMCS 2014)employee-related and maintenance of the system-relatedFigure 1. Slaughterhouser traceability system structureB.Main system flow chartThroughout the system, ZigBee coordinator form entire ZigBee communication network, waiting for routers and end nodes to join it. During slaughter surveillance process wireless RFID reader collects related node information, and then send it to the first bit machine through ZigBee network, and finally store related information into the database. The main system flow chart is shown in Fig. 2.Figure 2. System main program flow chart In wireless RFID reader, RF chip MF RC522 communicate with electronic tags following the communication protocol of ISO/IEC14443A . Through SPI(Serial Peripharal Interface), CC2530 controls communication between MF RC522 and type matched cards within the range of the antenna, and reads information in card, dealts with the information accordingly to make it compliant with the ZigBee protocol packets[5-6], and then sends the packets to the coordinator in ZigBee network following IEEE 802.15.4[7-10]. Coordinator connectes with the host computer via the UART interface, and ultimately send the data to PC for processing. Similarly, the host computer can send control commands to cooperate the electronic label, such as modification of the information.II.D ESIGN OF W IRELESS RFID R EADER The main function of mobile RFID reader is information collection, transmission and modification of slaughterhouse traceability. Hardware design of Wireless RFID reader system is about to design RF communication module circuit and ZigBee terminal node and ZigBee coordinator circuit.A.Design of RF Communication CircuitRF function consists of the microprocessor and RF chips, its main function is to communicate with the electronic tag for completing the exchange of the tag information [11]. The core chip of RF module is Philips MF RC522, electronic tags is M1 card produced by Philips. Fig. 3 shows RF communication module circuit.Figure 3. RFID read-write system radio frequency communicationmoduleFig.3 shows that RF power module 13.56MHz carrier signal modulated envelope signal sends to antenna module via pin TX1 and TX2. EMC filter circuit consisted of L1, L2, C11 and C12 ,with C5-C10 component drive the antenna, and then send out the signal. In the receiving end , stabilize the DC input voltage of RX pin stabilize through C3 and R2, and adjust the AC input voltage through C3 and C4.B.Wireless ZigBee module circuit designThe main function of ZigBee module is to send and receive data. The system uses a CC2530 With low power consumption produced by TI/Chipcon, It integrates IEEE 802.15.4/ZigBee RF transceiver and industry-standard enhanced 8051MCU kernel, the kernel control circuit is shown in Fig. 4.Figure 4. ZigBee core control circuit designC. Hardware interface circuit of CC2530 and MF RC522The system uses 32MHz crystal oscillator as a clock signal of CC2530 core controller, CC2530 communicates with RF module through SPI, P1_7 picks SDA end in RF chip MF RC522 as a signal control line. P0_1, P1_3 and P0_4 respectively pick D5, D6 and D7 end in MF RC522, control MF522 related registers write and read through SPI. P0_5 pick Reset pin of MF RC522 for the controller reset. Fig. 5 shows I/O interface connection of CC2530 and MF RC522.D. RFID reader application software designIn VS2008 development platform, we develop a PC reader software based on serial communication, and use the application software to read electronic label and specified block data, and midify specified block data.The PC reader application software is shown in Fig. 6.Figure 6. RFID readerapplication softwareThe process that user determine to modify data block 00 in sector 01 explain process of PC writing card. In specified data block, select data block in sector 01. Write data in the application software interface "modified data" column "01888888882510199990000251110088", clickon "Edit Data" button, the data is encoded as "19A2FFFFFFFFFFFF0401888888882510199990000251110088". Account for one byte of every two numbers, where "19" represents 25 bytes sending to the reader, "A2" indicates the data write instruction to be executed, "FFFFFFFFFFFF" is the initial cryptographic data block, "04" represents the fourth block of data block, PC software encodes the control command string for sending data into a binary format, the serial port is sent to the ZigBee coordinator through the PC, and then sent to the ZigBee coordinator through the terminal nodes, terminal nodes control MF RC522 store the data in electronic tag into the corresponding data block. In order to verify whether the data is correct or not, we can read the data in the specified block where just write into it. As Fig. 6 shows,select sector number, data block number ,click “read data ”, “data read ” box can show the data just written.E. The test results of Wireless RFID reader systemIn order to verify the stability and accuracy of the system, both indoors and outdoors to test the system. Indoor test is to detect the reader transmission distance through the wall, and outdoor is used to detect the reader transmission distance with no obstacle in open area .

滥用高科技工具英语作文
滥用高科技工具英语作文In the modern era, technology has become an integral part of our daily lives, offering unprecedented convenience and efficiency. However, the misuse of high-tech tools has raised serious concerns across various sectors of society. This essay aims to explore the negative implications of such misuse and suggest ways to mitigate its impact.Firstly, the misuse of technology in the form of cyberbullying and online harassment has led to a surge in mental health issues, particularly among the youth. The anonymity provided by the internet emboldens individuals to engage in harmful behaviors without fear of immediate repercussions. This has resulted in a toxic online environment where victims often suffer in silence.Secondly, the abuse of surveillance technology poses a significant threat to personal privacy. High-tech tools such as drones and facial recognition software, when used without proper oversight, can lead to a surveillance state where individual freedoms are compromised. The potential for these technologies to be exploited by governments or corporations for intrusive surveillance is a matter of grave concern.Moreover, the use of advanced technology in warfare has escalated the destructive potential of conflicts. Autonomous weapons systems and drones can be programmed to target and destroy without direct human intervention, raising ethicalquestions about accountability in warfare and the risk of an arms race.The environmental impact of high-tech misuse is also不容忽视(not to be ignored). The rapid obsolescence of electronic devices contributes to a growing electronic waste problem, as consumers are encouraged to upgrade to the latest models. This "throwaway culture" not only wastes valuable resources but also harms the environment through improper disposal methods.To address these issues, it is crucial to implement robust legal frameworks that regulate the use of high-tech tools. Education and awareness campaigns can also play a vital role in informing the public about the responsible use of technology. Furthermore, encouraging the development of ethical guidelines for technology use can help ensure that innovation serves the greater good rather than causing harm.In conclusion, while high-tech tools have the potential to enrich our lives, their misuse can have dire consequences. It is the responsibility of individuals, communities, and governments to work together to ensure that technology is used in a manner that respects individual rights, promotes social well-being, and protects our planet.。
