The invention provides an intelligent electric meter reading system based on single chip microcomputer control. The system mainly includes: a meter reading management system, a single chip microcomputer, a power line carrier module, a modulation-demodulation module and an electric meter. The modulation-demodulation module modulates the data transmitted from the single chip microcomputer into a B-PSK mode by a ST7540 chip, and transmits the mode into the power line carrier module or demodulates the data transmitted from the power line carrier module, and transmits the demodulated data to the single chip microcomputer; the power line carrier module puts the ST7540 chip modulated data to a power line and receives data information from the power line to conduct demodulation through the ST7540 chip; the meter reading management system is management software installed on a PC, is a unified management platform for managing users' electric meter data and sending instructions by a meter reading center, employs a serial assistant for substitution, and can write sent data and display received data at the serial assistant; and the electric meter saves current data into EEPROM, and is convenient for reading by the single chip microcomputer, and loss flash does not occur in the case of power failure.
Description
technical field [0001] The invention relates to an intelligent meter reading system based on single-chip microcomputer control. Background technique [0002] In recent years, with the reduction of the cost of single-chip microcomputer, the rapid development of communication technology and the diversification of communication technology, single-chip microcomputer control combined with communication technology has been more and more frequently used in people's lives. With the continuous deepening of my country's power grid construction, the number of household electric meters has increased sharply. The traditional manual meter reading method is time-consuming and inefficient, and the accuracy is not high. This traditional method does not meet the requirements of today's power reform. The table system is an inevitable trend. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a smart meter reading system based o...
