Title Design of The Electronic Components Test Instrument Based On SCM
Abstract
With the development of electronic industry,electronic components rapidly
increased;and also electronic components widely used gradually.The
electronic components and their organic connection constitute the hardware
of the elcetronic system of various functions.As for a elcectronic
system,even a few mistakes could bring about the whole system unable to
work.
【1 】 Therefore,the design of a reliable,safe,convinent electronic
components tester instrument,checking the components before welding is of
great practical necessity.
In the design of the hardware system, take the MCS-51 SCM as the core
resistance，through several simple test circuits,according the output of
the circuit,this electronic components tester instrument could
distinguish accurately good or bad of the capacitance,diode,triode,op-amp
741 and 555 chip,then display the result on the LCD 1602.
In the design of the software system, take Keil C51 as the simulation
platform,used the C language programming which compiled the system
application software.The system includes master routine module，display
module ， capacitance test module,diode test module ,triode test
module,op-amp 741 test module and 555 chip test module.
Through the simulation in proteus, the results show that the function and
the indexes of the system meet the design requirements.
