elevator control method

Abstract

The invention provides an elevator control method. According to the method, a hall sensor detects the level of a rotation output pin of a motor, a single chip microcomputer receives the level signal and detects running speed of the motor, so that the running speed of the motor can be effectively detected and controlled so as to control on and off of the motor. Positions of an elevating box are detected by a limit switch so as to control the running speed of the motor during an elevating process, and the problem that the elevator structure is damaged by the elevating box crossing a line due to the fact that the motor is running excessively can be effectively prevented. A delivery door and an antitheft separator plate are controlled to achieve antitheft. According to detection signals of the hall sensor and the limit switch, the single chip microcomputer controls the motor to run so as to control the elevating box to move up and down, and goods are prevented from being influenced by directly falling off.

Description

technical field [0001] The invention relates to the technical field of vending machine lifts, in particular to a control method for lifts. Background technique [0002] Due to the rising labor costs, coupled with the constraints of factors such as site limitations and shopping convenience, compared with the emergence of new distribution channels such as supermarkets and department stores, unmanned vending machines are a convenient shopping machine. Came into being. Vending machines are common equipment for commercial automation. They are not limited by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour micro supermarket. [0003] At present, when the vending machines commonly used in the market are selling goods, the goods are directly lowered from the cargo lane to the pick-up bucket, because the vending machine is divided into many cargo lane layers. As the number of layers rises, the falling grav...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a control method for the elevator. The control method of the elevator is simple, and the operation of the elevator box is controlled by using a DC motor, a Hall sensor and a main controller. The price is low and the safety factor is increased. The damage caused by the direct drop of the product solves the problem of safety accidents caused by the current overload during the operation of the lifting box
