S32、获取当前采集的压力数据，将当前采集的压力数据替换压力数据组中最旧的压力数据，得到新的压力数据组；S32. Obtain the currently collected pressure data, replace the oldest pressure data in the pressure data group with the currently collected pressure data, and obtain a new pressure data group;
S33、根据新的压力数据组计算压力变化率。S33. Calculate the pressure change rate based on the new pressure data set.
上述进一步方案的有益效果为：本发明通过计算压力变化率，再考虑与变化率阈值的大小，能够获得短时间内压力数据变化的速率，若压力变化率大于变化率阈值，则表明压力数据在持续变大，当前采集的压力数据与真实值存在误差，所以，有必要计算压力数据有效值，用以对当前的压力数据进行更新，提高升压过程中压力数据的精度。The beneficial effect of the above further solution is: by calculating the pressure change rate, and then considering the size of the change rate threshold, the present invention can obtain the rate of change of pressure data in a short period of time. If the pressure change rate is greater than the change rate threshold, it indicates that the pressure data is within It continues to increase, and there is an error between the currently collected pressure data and the real value.
