Special equipment sensor node data analysis method

The invention relates to a special equipment sensor node data analysis method. The method comprises the following steps: detecting operation data of special equipment through a sensor node x and a sensor node x0 and uploading the operation data to a processor; the method further comprises the following steps: step 1, establishing an analysis model: a) recording data calculation of a sensor node x; b) recording data delta3-delta2 = theta of a sensor node x0; step 2, acquiring running state data of the sensor node x and calculating data Kxy; step 3, if Sxy is equal to 0, judging that the sensor node x fails by the processor; otherwise, entering the step 4 for continuous judgment; 4, if delta4 is smaller than delta1, and delta5 is larger than 0 and smaller than delta2, the processor judges that the sensor node x is normal; otherwise, entering the fifth step for continuous judgment; step 5, if delta3-delta5 is greater than or equal to theta, the processor judges that the sensor node x is normal; and otherwise, th
