The invention discloses a feeder terminal analog quantity
verification method based on inter-core
shared memory communication, which relates to the field of
power equipment test and calibration, and comprises the following steps: establishing communication connection and analog quantity
signal connection between a
test board body and a feeder terminal; the
test board body sends a null drift calibration command, and the feeder terminal cooperates with the real-time core and the management core through the inter-core
shared memory to complete acquisition, calculation,
verification and storage of null drift parameters; the
test bench body sends a precision calibration command, and the feeder terminal cooperates with the real-time core and the management core through the inter-core
shared memory to complete acquisition, calculation,
verification and storage of an analog quantity
calibration coefficient; and the feeder terminal uses the stored null drift parameter and the
calibration coefficient to carry out subsequent analog quantity measurement. According to the scheme, the full-process closed-
loop control of the analog quantity verification of the feeder terminal from instruction issuing, parameter calculation verification to storage calling is realized, and the verification efficiency and accuracy are improved.
