ware, such as packet loss is the loss number plus 1. If the received data packet, receives the data packet number plus 1, and then sends the data were pared with data, if the data is correct, the number of packets plus 1, and error packets number plus 1. The last statistic results, can know the data packet loss and packet error rate. The 4 node to form a ZigBee work,1 of them as the gateway, the remaining 3 nodes for sensor node. Write a program to set:3nodes and gateway munications, puter terminal and the gateway is connected through RS232, terminal equipment software records from the 3node to receive data, nodes work at GHz frequencies, transmission of a byte of data, circular send 100 times. To obtain the final3 node test average as a result of the data analysis. Star work radio frequency munication BER test results as shown in table 1. Experimental analysis of: in a star work for data transmission, the test results significantly worse on a single point to single point transmission mode. This is mainly because, in the transmission process node must exist between the frequency interference and other interference. test System status and hibernation, respectively, using a multimeter to test the gateway node and the power consumption of sensor nodes, the test results listed in Table 2. Conclusion This paper analyzes the IEEE and ZigBee protocol, bined with the general development principles of munication systems and embedded syste ms, protocol on the μC / OSII operating system, select the appropriate hardware and software platform, focusing on software support for the platform, the software design of the overall structure of the munication protocol stack, and ultimately to achieve a pliant with the ZigBee specification car star wireless data acquisition work. The system has the following advantages: ① system easy to install. Wireless interconnection makes the equipment installation location is flexible to meet the requirements of the automation system is installed. It is simply that the power can take equipment. The work system can automatically plete the work configuration. ② scalability. Equipment within the coverage of the vehicle gateway, turn on the device, the node will automatically join the work.③ work selfhealing ability. If the work is a device fails, the vehicle gateway can automatically monitor, issue the mand the device reset and rework. 車載無(wú)線傳感器網(wǎng)絡(luò)監(jiān)測(cè)系統(tǒng)設(shè)計(jì) 康一梅,趙 磊,胡 江,楊恩博 (就 讀于北京航天航空大學(xué)) 摘要: 基于 IEEE 802. 15. 4和 ZigBee標(biāo)準(zhǔn)實(shí)現(xiàn)了一個(gè)車載無(wú)線傳感器網(wǎng)絡(luò)監(jiān)測(cè)系統(tǒng)。江漢大學(xué)畢業(yè)論文(設(shè)計(jì)) 外文翻譯 原文來(lái)源 Wireless sensor work monitoring system design 中文譯文 車載無(wú)線傳感器網(wǎng)絡(luò)監(jiān)測(cè)系統(tǒng)設(shè)計(jì) 姓 名 李俊杰 學(xué) 號(hào) 202007202041 2020 年 1 月 15 日 Wireless sensor work monitoring system design Kang yimei,Zhao lei,Hu jiang,Yang enbo (Study on Beijing University of Aeronautics and Astronautics) Summary: A car wireless sensor work monitoring system based on IEEE and ZigBee standards. With universal wireless sensor works, expansion of the scope of monitoring and monitoring functions for incar system, car data acquisition and condition monitoring of equipment status and the necessary equipment control, topology control, topology query functions. Keywords: wireless sensor works。 monitoring system Introduction In order to satisfy the people to car safety, handling and fort requirements, vehicle integrated with more and more electronic system .At present, car electronic equipment is widely used 16 or 32bit microprocessor control. Creating invehicle monitoring system based on IEEE and ZigBee standard for wireless sensor works, designed to achieve a more optimized wireless sensor works, the progressive realization of the work of automotive systems, intelligent and controllable to provide highCar System security. System design In this paper, the existing vehicle system, the data transmission mode is extended to the wireless transmission mode, the realization of a star work data acquisition system. And can place each data acquisition node of the acquired data is transmitted to the gateway, the gateway through the serial port to upload da
