The utility model employs the single-phase power meter with the addition of the electric circuit with SCM chip to realize the multi-rate power metering and charging, and has functions of LCD display and infrared and RS-485 communications, simple circuit structure, high reliability and operability for multi-rate charging.
Description
Technical field
The utility model relates to watt-hour meter, specifically a kind of single-phase electronic multi-rate electric energy meter.
Background technology
Existing watt-hour meter generally all is the mechanical type counting, causes reading error when manual metering easily, and it can't realize the charging of remote data transmission and the many rates of segmentation.It all is to adopt impulse hits to trigger that physical construction also causes device wearing and tearing, the sampling of electric pulse easily, good some undesired signals of filtering, take place easily electric weight many meters, count phenomenon less, measuring accuracy is lower.
Summary of the invention
The purpose of this utility model is a kind of single-phase electronic multi-rate electric energy meter that provides at the deficiencies in the prior art, it adopts the circuit that single-phase electronic energy meter installs the singlechip chip composition additional to carry out the charging of the many rates of segmentation, have LCD demonstration, infrared ray and RS-485 communication function, circuit structure is simple, the reliability height greatly facilitates the charging of day part.
The concrete technical scheme that realizes the utility model purpose is:
A kind of single-phase electronic multi-rate electric energy meter, comprise single-phase electronic energy meter, it is characterized in that having installed additional on the single-phase electronic energy meter by singlechip chip, the electric energy acquisition chip, level transferring chip, storage chip, clock chip, the circuit that modem chip is formed, the core of its circuit is a singlechip chip, when the electrical energy pulse that 13 pin of singlechip chip go out 22 human hair combing wastes of electric energy acquisition chip carries out high-speed sampling 20 pin of electric energy acquisition chip being carried out signal sampling confirms, 19 pin of singlechip chip receive and change from the infrared signal of modem chip, 18 human hair combing wastes of singlechip chip go out modulation signal and carry out the infrared data transmission by diode D6 after triode Q1 electric current amplify, level transferring chip is finished the conversion of single-chip microcomputer and host computer 485 signals of communication, storage chip is provided with the charging programming of 8 periods of two rates, clock chip provides the real-time time for system, battery BAI is a backup battery, battery BAI is the entire circuit power supply by diode D4 after the external power source dead electricity, capacitor C 12, C33 is a filter capacitor.
Circuit structure of the present utility model is simple, the reliability height, have LCD demonstration, infrared ray and RS-485 communication function, can many at times rates charge, greatly facilitate the calculating of multiple rate, especially the paired pulses collection has been adopted the software high-speed sampling and has been disappeared in real time and trembled filtering technique, guarantees that the electric pulse signal do not lose, and reliability improves greatly.
