Aiming at the requirements of "multi-meter unification" acquisition terminal technical specification for power user electric energy data acquisition system, a detection system was designed. The detection system has the function of acquisition terminal performance test,load and power consumption test, interchangeability test. Using the modular design thinking,selecting industrial personal computer as the main control unit,combining with human-computer interaction unit,acquisition terminal and matching module function detection unit, communication interface performance detection unit, power consumption detection unit,entity/virtual meter unit, ripple and stray sampling unit, oscilloscope, spectrum meter, RF source,baseband modulation unit,detecting multi-meter unification" acquisition terminal by standardized method. The experiment shows that the system meets the requirements of "multi-meter unification" acquisition terminal technical specification and is reliable.
