Abstract: A method for determining lubricant consumption by a transmission mechanism disposed on a machine tool includes steps of: a) estimating, based on an operational speed and a predetermined first predictive model, a total operational physical quantity; b) estimating, based on an individual operational physical quantity and the total operational physical quantity, a total operational count; c) receiving actuation information from the machine tool, and calculating a partial operational count based on the actuation information; and d) calculating, based on the partial operational count and the total operational count, a ratio between an amount of lubricant consumption within a time period and a total amount of lubricant.

Abstract: The present disclosure provides a method and device for identifying a product purchased by a user and intelligent shelf system. The method includes acquiring a weight of products carried in a container, acquiring a first monitoring image acquired in a monitoring area corresponding to the container, identifying the first monitoring image, and obtaining an identification result, wherein the identification result comprises user identity information when it is determined that the weight of the products is reduced, acquiring a time when at least one product carried in the container is picked up, and determining information of at least one picked-up product, obtaining the user identity information corresponding to the at least one picked-up product, and associating the user identity information with the information of the at least one picked-up product.

Abstract: A split detection device includes: a detection unit, which includes a detection casing and a sensor that is mounted inside the detection casing; a processing unit, which includes a processing casing and a processor that is mounted inside the processing casing; a connection unit, which is electrically connected between the sensor of the detection unit and the processor of the processing unit; and a transmission unit, which is electrically connected between the processor of the processing unit and an external device. By setting up the sensor and the processor inside different casings to be separate from each other, influence of the processor on the sensor can be reduced to thereby improve accuracy of detection.
