Street lamp remote monitoring system based on GSM technology
At present, the communication scheme of the remote control system generally adopts wired and wireless methods. Wired data transmission methods generally use dedicated lines, such as CAN bus, telephone line, Ethernet and so on. Such schemes generally require special lines to be laid, the engineering volume and investment are relatively large, and they are easily interfered by urban construction. At the same time, the equipment is poorly spread and the line is aging. 2004-07-21 is mainly engaged in electronic information system integration and lighting electronics. Technical Research; Shao Yufeng (1979-), male, master student, currently engaged in the research of electronic information system integration direction; Zeng Wei (1979-), male, teaching assistant, is currently engaged in the research of embedded systems and electronic design automation. Repeat investment. Compared with wireless, data transmission by data line has the advantages of better reliability and larger capacity. However, no matter whether you are wiring or renting a dedicated line, the installation is not as flexible and fast as wireless. When transmitting over long distances, the equipment and operating costs are higher than the wireless mode. Wireless data transmission has become more and more widely used with the popularization of computers and the expansion of automation. Generally, there are conventional frequency band digital radio stations, GSM short messages and GPRS, as well as infrared and Bluetooth. Different platforms have different characteristics due to their different system architectures and terminal functions, so each has its own application field. At present, many urban streetlight control systems use digital radio stations as communication means, but when the system is put into use, not only need to apply for frequency and set up outdoor antennas or iron towers, but also the price of digital radio stations is high, and its dedicated network also needs regular maintenance. When the number of monitored points on the site is large, the cost of the system is greatly increased. If SMS is used for data communication, the GSM short message will be more and more widely used in the future smart home appliance field with its own advantages. Applications.
