Design of hardware-in-loop simulation testing systems for the embedded software of electronic watt-hour meters

In the embedded software testing of electronic watt-hour meters that depends on the target and external interaction devices, the problem that the running environment should be geared to the testing environment was a key technical issue in the simulation test. A method for a hardware-in-loop simulation testing system for the embedded software of electronic watt-hour meters was offered on the basis of the embedded software simulation testing method. The system was mainly used to establish the simulation testing environment for the embedded software testing of electronic watt-hour meters to measure the embedded software system for dynamic testing. The computer simulation system that simulated the external interactive equipment and the simulation model of the testing environment were explained in detail. Through the testing of electronic watt-hour meters, this method proves to be effective for the embedded software testing of electronic watt-hour meters.
