Intelligent commodity anti-theft alarm detection method

The invention provides an intelligent commodity anti-theft alarm detection method. The method comprises the following steps: collecting commodity sensor data and a signal intensity value in real time; sliding window filtering processing is carried out; calculating a resultant acceleration and an Euler angle; calculating linear acceleration and angular acceleration; performing statistical analysis on the linear acceleration and the angular acceleration to obtain characteristic values; distinguishing different user activities and commodity postures; behavior factors are set; upper envelope line taking operation is carried out on the signal intensity value, and the probability of potential theft behaviors is estimated; and setting different early warning prompts according to the potential theft behavior probability. In anti-theft display of retail commodity exhibition, wireless anti-theft is achieved through the Bluetooth wireless technology, no alarm is given within an effective range, immersive experience of c
