The programmed temperature tester for mechanical and electrical products has the characteristics of high precision, intelligence, low cost, standard embedment decision, available network remote communication and the like.
Description
Technical field
The present invention relates to a kind of temperature testing device, be specifically related to a kind of electronic product program control temperature tester.
Background technology
Temperature test is one of key project of electronic product electrical safety conformity assessment, and namely in normal operation, the temperature rise of test products all parts determines it whether in the scope that standard specifies.
Existing temperature measuring device only carries out record to temperature signal, automatically can not judge test result.The multichannel temperature tester heart of domestic-developed draws, and mainly thermopair data is read people's computing machine and carries out analytical calculation, can only realize multichannel temperature collection, display, not embed temperature rise testing standard.This YOKOGAWA of Et company DR 130 type thermometer is widely used also just to collection and the record of temperature signal in electrical safety laboratory.By reading the thermograph report that temperature measuring device generates, according to temperature rise standard, Test Engineer judges that whether electronic product is qualified, testing efficiency is lower.
Summary of the invention
The present invention aims to provide a kind of temperature test meeting various safety standard that can automatically generate and reports.
Technical program of the present invention lies in:
A kind of electronic product program control temperature tester, system is made up of host computer and slave computer double-decker; The slave computer of described program control temperature tester forms primarily of by K type thermopair, signal condition, channel selecting, A/D sample circuit, Advanced Single machine and communication interface; Wherein, RS 232, the data interaction of tcp/ip communication Interface realization is passed through between slave computer and host computer.
Preferably, described K type thermopair, the temperature measurement range of design is 0-450 degree.
Preferably, described signal conditioning circuit by accurate amplifier chip OP07A, zero-regulator resistor, go lotus root electric capacity and correlation proportion resistance to form.
Preferably, described A/D sample circuit forms primarily of AD 1674,74HC74 and 74HC00.
Preferably, communicate primarily of MAX 232,9 needle serial ports and electrochemical capacitor composition.
Technique effect of the present invention is:
This instrument possesses that precision is high, intelligent, cost is low, embeds criterion and possess the features such as network telecommunication.
Accompanying drawing explanation
Fig. 1 is the acquisition terminal theory diagram of temperature measuring device of the present invention.
Embodiment
A kind of electronic product program control temperature tester, system is made up of host computer and slave computer double-decker; The slave computer of described program control temperature tester forms primarily of by K type thermopair, signal condition, channel selecting, A/D sample circuit, Advanced Single machine and communication interface; Wherein, RS 232, the data interaction of tcp/ip communication Interface realization is passed through between slave computer and host computer.Described K type thermopair, the temperature measurement range of design is 0-450 degree.Described signal conditioning circuit by accurate amplifier chip OP07A, zero-regulator resistor, go lotus root electric capacity and correlation proportion resistance to form.Described A/D sample circuit forms primarily of AD 1674,74HC74 and 74HC00.Communication is primarily of MAX 232, and 9 needle serial ports and electrochemical capacitor form.
Principle of work and the process brief introduction of system are as follows: first, the temperature inversion of 16 dut temperature points is hot thermocouple electromotive force (for weak voltage signals) by 16 road K type thermocouple probes of acquisition terminal, then the signal conditioning circuit through each road completes cold junction compensation and signal amplifies, then 1 analog switch is selected to carry out passage bridge control by 16, this road of gating then enters A/D below, transfers digital signal to.Then Advanced Single machine carries out data acquisition and data processing to digital signal, is sent in host computer PC by data result finally by RS 232 or tcp/ip communication interface.The Research on Automatic Measuring System of Temperature software of host computer then receives the data result of slave computer by communication interface, after the data processings such as nonlinear compensation, obtain raw temperature data, then the display of data real-time curve, data preservation etc. are carried out, finally according to the contrast embedding temperature rise standard and dut temperature data, whether intelligent decision electronic product temperature when normal work is qualified, and printing reports.
