The invention discloses a fundamental frequency extraction method based on a statistical method and applied to cable force detection. The fundamental frequency extraction method based on the statistical method and applied to cable force detection comprises the following steps that (1) FFT conversion is conducted on data collected by an acceleration sensor on an inhaul cable, the first N maximum frequency points of the data generated after FFT conversion are extracted according to a peak value, and the measuring time is recorded and serves as a piece of record; (2) weighted statistic is conducted on historical data of multiple time points, the frequency point with the largest weight is found, and namely the frequency point with the largest weight is a needed fundamental component. According to the fundamental frequency extraction method based on the statistical method and applied to cable force detection, fixed-point FFT conversion can be conducted on a time domain signal in advance through a DSP chip, time waste and resource waste which are caused in the process of data transmission in a project are reduced. The statistical method is applied, and therefore fundamental frequency measuring errors caused by one-time measurement can be reduced. In addition, manual intervention can be conveniently conducted, and manual adjustment can be conducted on obvious errors.

The invention discloses a dynamic overheating early warning motor, which belongs to the field of electric motors. Through the setting of the color delay warning bar, when the temperature is close to the stable operating temperature, the color delay layer gradually heats up and presents a flow state, thereby extending along the color delay warning bar. At the same time, the bamboo-shaped stacked tube is extended and the pneumatic ball is pushed to accelerate the flow of the color extension layer, so that the color change can be quickly presented visually, and the staff can be visually reminded that there may be a risk of abnormal temperature rise in the motor, which is convenient for them to carry out manual work in time. Intervention to reduce the impact of abnormal high temperature on motor life and operation stability. At the same time, when the colored magnetic powder on the pneumatic ball is exposed and gradually adsorbed on the inner wall of the color delay warning strip, it means that the surface temperature of the motor is higher than the safe operating temperature, which is convenient for the staff. The temperature of the motor is judged at this time, so that manual intervention can be carried out in time.

The invention provides an unattended supermarket settlement method based on a conductive ink pressure sensor. The film pressure sensor is used to detect changes in the weight of customers and goods in real time. The customer obtains the unique identification of the customer at the entrance area, and the background server compares the unique identification of the customer with the initial weight of the customer. Carry out association and realize customer positioning, the background server determines the goods taken by the customer according to the change of customer weight data and product weight data and updates the settlement list, and finally deducts the settlement fee according to the settlement list to complete the shopping behavior. The unattended supermarket settlement method based on the conductive ink pressure sensor provided by the present invention is ingenious in conception, low in cost, convenient in operation, simple in required algorithm, low in error rate, can meet the needs of a large number of customers shopping at the same time, and meet the needs of bulk goods.
