The invention discloses an electric energy meter metering pulse analog system and an output method for electricity consumption information acquisition equipment. A first signal output end of a micro-processing system in the system is connected with a signal input end of a display system; a second signal output end of the micro-processing system is connected with a signal input end of an interface output system; a first signal input end of the micro-processing system is connected with a signal output end of an isolating power system; and a second signal input end of the micro-processing system is connected with a signal output end of a key input system. The output method comprises the following steps: performing electric energy metering pulse analog output under equal electric quantity and different powers; performing electric energy metering pulse analog output under equal power and different electric quantities; performing electric energy metering pulse analog output under different electric quantities and different powers; and performing conversion output of electric quantity, power, pulse and time. The system and the output method have the advantages that eight paths of active pulse output and eight paths of passive pulse output can be simulated at one time, 16 paths of pulse input can be driven by each path of pulse output at most, and the system and the method can be conveniently used for verifying the compliance of the electricity consumption information acquisition equipment on a large scale.
Description
technical field [0001] The invention relates to a metering pulse simulation system and an output method of an electric energy meter used in electricity information collection equipment, and belongs to the field of test verification of electricity information collection equipment. Background technique [0002] An important function of the electricity information collection equipment is to measure the electricity and power of the energy meter by collecting the metering pulses of the energy meter. However, the verification of this function of the electricity information collection equipment can only be verified by some general-purpose pulse meters or by using Electronic information collection equipment function test bench for verification. Some of these verification equipment are general-purpose equipment, which are expensive and complicated to operate, and some technical parameters do not fully meet the relevant requirements of power consumption information collection equipmen...
