I. System Overview: Since 2006 IBM company made smart grid solutions since the smart grid has become the object of focus on the development of all countries. The KB3030-NRC smart grid remote copy to theft terminal, based on my company KB3030-N GPRS DTU (Data Terminal Unit) basis, specifically for smart grid applications and the development of a product. KB3030-NRC also has meter and sensor camera, both the remote copy to achieve power, but also to achieve the grid automatically records maintenance supervisors, but also can prevent theft and sabotage against power meter, power box. Meanwhile, KB3030-NRC in the use of the temperature range, vibration, electromagnetic compatibility and interface are uniquely designed to ensure job stability in harsh environments. Because GPRS wireless data communication mode, therefore, the product has a wide range of communications, data transmission stability and reliability. Also, because the system uses the B / S architecture, making management of the entire system is no longer subject to time and geographical constraints, can always use the terminal to access the Internet to manage. System is simple to use, easy to operate, highly practical. System features: stable performance, transferring large amounts of data is never loss; transmission speed, 640 * 480 pixel picture can transfer is completed in about 30 seconds; mature and reliable server software, software development and applications for many years??? multithreaded mode maintains a large communication data throughput;? publishing software easy to operate, very user-friendly interface, users can easily understand and use;? receiving terminal software automatically displays the site online and offline, and receiving process state;? manual camera supports both remote and remote automatic camera, and also supports the scene triggered camera (sensor);? receive photos easy, users simply connect to the Internet at any one terminal can view live camera photos and consumption data; ? system is safe and reliable, software users have strict password authentication mechanism. Company ID verified by the server, the user account authentication database; two. ? GPRS technical parameters and features standard industrial grade product, EMC anti-jamming design, ability to adapt to the environment;? Independent research and development, 32 ARM7- CPU with embedded real-time operating system;? Watchdog embedded chip, offers a variety of reset mechanism to software control, to achieve the perfect industrial security mechanism;? the operating frequency using the 850/900/1800 / 1900MHz, quad-band applicable to all countries (including South America);? advanced and strict data communication protocol, comes with error correction and encryption. Data transfer is never loss; IP automatic registration mechanism can achieve a variety of service models and build a complete ultra-large-scale wireless applications; remotely modify the parameters:?? Support SMS modify parameters and modify network parameters; automatic camera features:? Someone go after the sensor detection range, KB3030-NRC that would be 10 times the current viewport camera, and save the photos back to the server; powerful communication standby function:? support connected to the main server and backup server if the primary server automatically switches problem, automatically connect to the backup server;? powerful server software support, server software applications for many years, powerful, sophisticated;? support private APN, data center support fixed IP and DDNS;? may be dormant through SMS , wake up, reboot and other operations (see SMS Configuration Protocol); Industrial Temperature Range:? Working temperature: -40 ℃ -80 ℃, at -40 ℃ when communication is not affected. Three, GPRS technical parameters of the band:????
