Meanwhile microcontroller operation result stored in the chip FlashROM (flash memory) or E? 2PROM (electrically erasable memory) After setting the parameters within calculates comparison, according to processing results and control requirements smart meters, the corresponding output control signals (e.g. alarm device is triggered, relay contacts, etc.). Also smart meter company, intelligent instruments and PC can also be composed of a distributed control system, by the microcontroller as the next crew collected various measurement signal and data smart meter technology to transmit information via the serial communication to the host machine --PC machine intelligent electricity instruments, globally managed by the PC. Compared with traditional instrumentation, intelligent instrument has the following features: ① automatic operation. The entire measurement process instruments such as keyboard scan, range selection, switch to start closed, collection, transmission and processing of data and display the print so with a microcontroller or a microcontroller to control the operation to achieve fully automated measurement process. Smart meter technology, smart meters, power measurement since the force measuring instrument is provided by Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
