Abstract

The invention discloses an electric energy meter terminal base temperature control method and device based on a fuzzy PID algorithm, and relates to the field of electric energy meter terminal base temperature control. The electric energy meter terminal base temperature control method comprises the steps of collecting the actual temperature of an electric energy meter terminal base at each sampling moment; calculating a deviation value and a deviation value increment between the actual temperature of the electric energy meter terminal base and a preset temperature; carrying out fuzzy processing on the deviation value and the deviation value increment, determining a fuzzy relation between the PID parameter and the deviation value and the deviation value increment, and establishing a fuzzy rule table; modifying the PID parameter on line according to a fuzzy rule, and adjusting a PWM control parameter; and enabling a heating module to heat according to the adjusted PWM control parameter. According to the method, fuzzy self-tuning of PID parameters is realized, the control precision and stability of temperature control of the terminal base of the electric energy meter are improved, the heating time is effectively controlled, the temperature of the heating module is prevented from being too high, and the service life of the heating module is prolonged.

Description

technical field [0001] The invention relates to the field of temperature control of a terminal block of an electric energy meter, in particular to a method and a device for controlling the temperature of a terminal block of an electric energy meter based on a fuzzy PID algorithm. Background technique [0002] In the field of modern industrial instrumentation, temperature has become a very important indicator that restricts the long-term stable and reliable operation of instruments and equipment. As the foundation and key of power marketing, power metering needs to be transformed with the progress of the power industry to measure power more accurately, provide a scientific basis for power marketing, and promote a significant improvement in power marketing. However, in the actual transformation process, there are still many problems, which make the actual transformation effect difficult to meet expectations. During the long-term operation of the electric energy meter, the ampl...
