Inventory detecting device and method for vending machine

Abstract

Provided are an inventory detecting device and method for a vending machine. The inventory detecting device comprises a vending machine master control system and a plurality of inventory detecting facilities. Clip goods channels with push rods are adopted in the vending machine, the inventory detecting facilities are arranged on trays respectively, and each inventory detecting facility comprises asalve control CPU. A serial communicating port of each slave control CPU is connected with a second RS485 interface through an RS485 conversion chip in a half-duplex communicating mode, I / O interfaces of the slave control CPUs are connected with a plurality of infrared sensors and a plurality of push rod driving motors, and each goods channel is correspondingly provided with one infrared sensor and one push rod driving motor. The infrared sensors are groove type optocouplers, and the tail ends of the push rods of the clip goods channels are mounted in detecting grooves of the infrared sensors. The vending machine master control system comprises a master control CPU, the master control CPU is connected with a door control switch, a displayer and a first RS485 interface, and the first RS485interface is connected with the second RS485 interfaces of the inventory detecting facilities in a half-duplex communicating mode. The inventory detecting device can automatically detect the goods adding number and the inventory, and the use performance is improved.

Description

technical field [0001] The invention relates to automatic vending machines, in particular to an inventory detection device and method for automatic vending machines. Background technique [0002] In the management of vending machines, some have no inventory management, some inventory management requires the vending machine administrator to manually set the current inventory quantity after adding goods, and some automatically detect the inventory quantity with poor accuracy. When the inventory management of vending machines is inaccurate, there may be short-selling situations, which may cause complaints, or there may be situations where stocks cannot be sold, resulting in operational losses. When the vending machine administrator adds goods, it is a better innovative method to use inventory detection methods and equipment to realize real-time automatic inventory management. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
