S32: and obtaining each second training score value of the electrocardiogram patch positioning training of the current training personnel aiming at each body characteristic parameter according to each second error value.
Specifically, the preset position is compared with the reference position, preferably, the range area of the preset position is compared with the range area of the reference position, and the area ratio is recorded as a first difference; it should be noted that: when the preset position does not completely cover the reference position, prompt information is generated so that training personnel can correct errors in time and training efficiency is improved; comparing the central point of the actual position with the central point of the reference position to obtain a second difference value, and taking the first difference value and the second difference value as a second error value; when the first difference value is close to 1 and the second difference value is smaller, the cognition of the current training personnel on the reference position is more accurate, when the first difference value is far from 1 and the second difference value is smaller, the cognition of the current training personnel on the range of the reference position is required to be improved, the cognition on the actual position of the patch is more accurate, when the first difference value is far from 1 and the second difference value is larger, the cognition of the current training personnel on the range of the reference position and the actual position of the patch are required to be improved; and obtaining a second training score value according to the first difference value and the second difference value.
