Simple and convenient autonomic and automatic meter adjustment method

Abstract

The invention relates to a simple and convenient autonomic and automatic meter adjusting method. According to the method, an autonomic and automatic meter adjustment mechanism for an electric meter is used for the meter adjustment, so that the adjustment operation of the electric meter can be performed without a meter adjustment table but only by a power source, and therefore, not only the meter adjustment steps are simplified, but also the cost is reduced; and the method has high meter adjustment precision and high production repeatability, is favorable for production automation, reduces the influence of many human factors on the product quality, ensures the stability and reliability of the product quality, and greatly improves the qualified rate of the product.

Description

technical field [0001] The invention relates to a simple and convenient automatic meter calibration method. Background technique [0002] Electronic energy meters are gradually replacing traditional mechanical energy meters due to a series of advantages such as high precision, small starting current, good error linearity, powerful functions and easy expansion, strong anti-theft ability, and remote monitoring. The meter calibration process is an important process in the production process of electronic energy meters, which directly affects the pass rate of the factory inspection of electronic meters, and also affects the online time of electronic meters. [0003] The traditional manual calibration method needs to manually calibrate the electric meter with electric soldering iron, screwdriver and other tools.

Problems solved by technology

[0003] The traditional manual calibration method needs to manually calibrate the electric meter with electric soldering iron, screwdriver and other tools. The use of these tools will cause damage to the meter. Moreover, this calibration method has low adjustment accuracy and poor production repeatability, which is not conducive to production automation. , and a large number of human factors will affect the product quality, and the stability and reliability of the product cannot be guaranteed

[0004] The existing software meter calibration system requires the cooperation between the upper computer, the electric meter, the meter calibration station, and the standard meter. The meter correction station includes a standard meter and a power source. The price of the standard meter is relatively expensive, which makes the production cost of the meter relatively high, and The algorithm used by the software in the prior art is complicated, and the operation is complicated. Every time a meter is calibrated, the parameters need to be set once, which takes a lot of time and is not efficient.

[0005] With the development of science and technology, the traditional manual meter calibration method and the existing software meter calibration method can no longer meet the needs of mass production. It is urgent to develop a simple meter with automatic meter calibration mechanism to improve product quality and production. efficiency
