The invention provides a simulation detection system of a metering core, as shown in figure 1, comprising:

the detection system master station simulates and outputs a preset amount of metering data, divides the metering data into a plurality of parts, presets a first part of the metering data on the metering core analog board, inquires the number of metering data which are not read in a metering core analog board queue, and sends a part of the metering data to the metering core analog board after inquiring that the metering data in the queue are lower than a preset value each time until all the metering data of the plurality of parts are sent;

the metering core simulation board is used for placing the metering data of the first part into a queue, and placing the metering data of the remaining part into the tail part of the queue after receiving the metering data of the remaining part;

and the management core reads the metering data from the head of the queue and detects the metering data.

The metering data is analog metering data or collected metering data.

After the management core sends a data reading request to the metering core simulation board, the metering core simulation board feeds back data at the head of the queue to the management core.

And after the query request of the detection system master station is passed, the metering core simulation board feeds back the record to the detection system master station.

Wherein the preset value is 25-35% of the total number of data in the queue.

The invention also provides a simulation detection method of the metering core, as shown in fig. 2, comprising the following steps:

using a detection system master station to simulate and output a preset amount of metering data, dividing the metering data into a plurality of parts, and presetting the metering data of a first part in a metering core simulation board;

putting the metering data of the first part in the metering core analog board into a queue;

reading the metering data from the head of the queue by using a management core, and detecting the metering data;

inquiring the number of metering data which are not copied in the metering core analog board queue, and after the metering data in the queue are lower than a preset value after each inquiry, sending a part of metering data to the tail of the queue of the metering core analog board until all the metering data of a plurality of parts are sent;

as shown in fig. 3, the method comprises the following steps:

and constructing test data under the overvoltage and overcurrent working conditions, wherein the test data can be customized according to requirements and can also be real metering data.

And importing the test data into a test system.

After the detection process is started, a certain amount of test data is led to the metering core simulation board.

The metering core analog board stores the received data in a data queue of the storage area in sequence.

When the management core requests data from the metering core through the SPI communication interface, the metering core takes out the data from the head of the queue and returns the data to the management core.

The master station circularly inquires the data surplus of the metering core, and the metering core returns the data surplus.

When the main station inquires that the data residual quantity is lower than a certain proportion, such as 30%, a certain quantity of data is issued to the metering core simulation board again.

And repeating the steps 4-7 until the detection is finished.

The metering core simulation board can normally communicate with the management core, the data preset by the master station can simulate various working conditions, when the simulation system and the management core carry out data interaction, the simulation system can quickly respond to the request of the management core without data leakage, the management core can normally work, and the data response under various severe working conditions is simulated by controlling the data content responded by the metering core simulation board, so that potential safety hazards possibly existing in the management core software can be quickly and efficiently detected.
