The invention discloses an intelligent meter reading centralized control system for a PMI power system and a teaching experiment platform based on the centralized control system. The intelligent meter reading centralized control system for the PMI power system comprises a power system, a collector unit, a centralizer unit, an electricity meter, an analog type electricity meter, a general packet radio service (GPRS) wireless communication module, a carrier communication module, an Ethernet communication module, a liquid crystal display (LCD) screen, a state indicating lamp module and a master station system, and the control system achieves the portable and flexible remote and automatic meter reading function. The intelligent meter reading teaching experiment device for the power system comprises an experiment table body, the intelligent meter reading centralized control system for the PMI power system, an experimental panel screen and a computer. The teaching experiment device is suitable for experimental teaching of correlated curriculums, is used for cultivating the practical skills and abilities of undergraduates and postgraduates majoring in power and can serve as a practice device for an induction training platform of technicians in electricity.
Description
technical field [0001] The invention relates to the field of power system automation, in particular to the intelligent meter reading technology of the power system. Background technique [0002] The intelligent meter reading technology of the power system is a new technology that applies automatic data collection, transmission communication and centralized processing to power supply and management, and can fundamentally solve various disadvantages caused by traditional manual meter reading. At present, there are two related devices of the power carrier centralized meter reading system, which are GPRS concentrator and collector, Ethernet concentrator and collector. But they mainly have the following obvious defects: (1) remote communication adopts GPRS communication, which is affected by signal strength, and the communication cost is high, which is not conducive to large-scale use; [0003] In view of the above shortcomings, the power line carrier method can be used, that is...
