Description

technical field [0001] The invention belongs to the technical field of electric energy quality, and in particular relates to a coordinated control system of distributed reactive power compensation devices based on RS485 bus. Background technique [0002] In industrial places, it is often necessary to perform voice calls and text data exchanges between a local terminal and a host terminal. Sometimes the mobile phone signal is poor in industrial places, and the Internet installation is inconvenient, that is, mobile phone communication and network communication are not very convenient. Most current voice-enabled control devices are too complex, cumbersome, and costly. In order to adapt to the simple remote communication and display functions, this system adopts a system composed of a single-chip microcomputer and a liquid crystal display (LCD) display terminal. Contents of the invention [0003] In view of the above problems, the present invention provides a voice terminal ...
