The invention relates to the field of instruments and meters, and concretely relates to a test method for software separation of a multi-core intelligent electric meter. The method is used for connecting a metering core and a management core of the multi-core intelligent electric meter with a simulation part respectively. Through controlling a simulation part with an upper computer, metering core software and management core software are separated for metering accuracy testing and / or data interaction correctness testing and / or fault influence testing; and the test method can be used for testing software independence, communication reliability and / or data interaction real-time performance and / or big data interference of the metering core and the management core of the multi-core intelligent electric meter.
Description
technical field [0001] The invention relates to the field of instruments and meters, in particular to a testing method for software separation of multi-core smart meters. Background technique [0002] Based on the IR46 multi-core smart energy meter, the function of the meter is divided into two independent parts, the metering core and the functional core, which are not interfered with each other. According to the principle of physical separation, they are respectively realized by two independent chips that do not interfere with each other, and the software separation is finally realized; , The metering core provides legal data such as power and clock, and the power and clock of the management core are based on the metering core and synchronized in real time. [0003] Since the metering core and the management core communicate through the SPI bus, the data interaction and mutual influence between the two cores cannot be tested by conventional means. At present, programmers c...
