The Research And Development Of Automatic Detection System For Electromagnetic Energy Efficiency Of Household Appliances

Energy efficiency is an important technical indicator for evaluating the energy use and conversion of energy-using products and their energy-saving characteristics.Energy-efficiency standards and energy-efficiency identities have been proven to be the best ways to reduce energy consumption and provide significant environmental benefits.The energy efficiency labeling measurement and inspection system is an important technical means to ensure the accuracy and reliability of the energy efficiency value.China is a large country in the production and use of household electromagnetic cookers.There are many problems in the energy efficiency inspection of traditional household cookers,such as a low degree of automation;manual operations lead to larger errors in detection results;and poor traceability.In order to solve the above problems,this paper designed and developed a set of automatic detection system for household cookers' energy efficiency.The establishment of the system will make up for the detection of energy efficiency of electromagnetic cookers in the autonomous region.Technical blank.This system is mainly based on LabVIEW development,design of a set of automated test platform,can achieve real-time display of test data,save,and historical data query and other functions.By analyzing the current status of energy efficiency testing at home and abroad and the shortcomings of traditional energy-efficiency detection methods for household electromagnetic cookers in China,we compared the energy efficiency detection of household electromagnetic cookers in China and European countries from four aspects: environmental conditions,measuring equipment,testing methods,and energy efficiency labeling.According to the requirements of various parameters in China's home electromagnetic cooker energy efficiency verification procedures,the hardware design and selection of this set of automation system were completed.The hardware of this set includes: industrial control computer,power analyzer,digital multimeter(temperature acquisition Instrument),temperature sensor.In the choice of temperature sensor,the PT100 platinum resistance and the armored thermocouple two kinds of temperature sensors are mainly used for calibration and performance comparison.After comprehensive consideration,the PT100 platinum resistance is finally selected instead of the mercury thermometer in the traditional measurement system.For the design of software part,a human-computer interaction platform based on LabVIEW is built,and the mutual visit between the software and the Access database is realized by using the Microsoft ADO and SQL statements in the LabSQL toolkit.The connection between the upper computer and the measuring instrument is completed through the SCPI instruction,the USB to the serial port and the instrument driver configuration protocol.The main interface of the system is designed four modules,which are the test curve display module,the thermal efficiency detection module,the standby power detection module and the data query moduleComparing and analyzing three home-use electromagnetic cookers with different energy efficiency levels,and verifying the feasibility,accuracy and traceability of the system through the evaluation of the uncertainty of the whole set of automated inspection systems.Compared with the stove energy efficiency detection system,the overall uncertainty of this set of automation system is greatly reduced,and the detection accuracy is greatly improved,which provides a reference value for the automation of other energy efficiency detection systems related to temperature measurement.
