Because the eight groups of infrared sensing switch circuits are consistent in structure and working principle, each group has the same multiple paths, and each path is consistent in structure and principle, the prompting circuit U3 sends a short message as long as any goods lattice of one layer of goods shelf is out of stock after the eight groups of infrared sensing switch circuits work by being powered on every minute; because the power-on working time of the eight groups of infrared induction switch circuits of the eight-layer goods shelf is different (one minute is separated) under the action of the query circuit, when the short message sending time is different when the single goods grid of the one-layer goods shelf is inquired to be out of stock, the owner can determine which vending machine is out of stock at specific place according to the telephone number of the received short message, and can also directly know which layer of the automatic vending machine is out of stock according to the receiving time of the short message (for example, the short message received by 2 minutes at 10 o ' clock is that the second layer of the goods shelf is out of stock, and the short message received by 3 o ' clock at 10 o ' clock is that the third layer of the goods shelf is out of stock at night), and can carry the goods to the site for replenishment according to the own goods placing habit (for example, the second layer of the goods is out of stock, and the corresponding goods such as cigarettes, snacks, drinks and the like are respectively placed in the plurality of grids at the second layer), the invention can carry out stock in a targeted way, can carry out replenishment in the first time, and can not cause that goods needing stock is not carried when stock is carried, thereby bringing convenience to a machine owner, ensuring convenient shopping of a shopper and reducing various unnecessary expenses of the machine owner. Under above circuit effect, every day, for example 10 o 'clock to 10 o' clock 8 minutes evening, the inquiry circuit can carry out the starved goods inquiry to eight layers of goods shelves of automatic vending machine in proper order, can send out the SMS through suggestion circuit U3 the very first time after a single goods check starved goods of a certain floor, and the user just can carry out the pertinence stock (carry out the pertinence stock to the multiple goods of each floor, reduced under the circumstances of knowing, take the required whole goods of eight layers of goods shelves and carry out various inconveniences that the stock brought). Based on the above, the invention has good application prospect.
