Guangdong vending machine discussed with you the working principle of unmanned vending machine? The author brings us the knowledge of unmanned vending machines, let's discuss it together! A vending machine is a machine that can automatically pay for goods based on the coins you put in. The main components are: body shell, commodity storage cabinet, control board, coin recognizer, sensor, power supply and lighting system of the whole machine, cooling and heating system, Internet terminal, programmable logic controller (PLC). Among them, the most important is the programmable controller (PLC), which coordinates the operation of the entire vending machine. The programmable controller is based on the microprocessor, and combines the relay control system with computer technology, which is convenient, practical and easy to program. PLC models are diverse, PLC--CPM1A-V1 and AC100-220V are widely used in vending machines. However, these two models have good stability and poor compatibility, making it difficult to adapt to the development of high-tech. The specific shopping process is as follows: 1. The consumer puts the coin into the coin machine (coin machine or paper money machine), and the coin recognizer recognizes the coin. If counterfeit currency is detected, data will be recorded and spit out. 2. After the coin is identified, the customer presses the button to purchase the product according to the amount. If the amount is insufficient, the corresponding product cannot be purchased. 3. The sensor receives the button information and drives the relevant components. The goods are delivered to the pick-up port. 4. Customers can continue to purchase or refund according to the balance. If the customer does not move within 15 seconds, the vending machine will automatically refund the currency. 5. The customer picks up the goods and completes the shopping.
