Development of a Software System for Controlling Dosing Machines †.

The liquid dosing system consists of machines and a computer (PC). The machines and the computer are connected to each other and communicate via the RS485 interface. The software installed on a computer (PC) consists of two separate modules (applications)—"server" and "operator". The server runs continuously and communicates to and from the machines. Through the operator module, the nomenclature of customers, liquids, and cards can be created and edited. The operator module makes it possible to perform various operations such as loading credit on a card, blocking and unblocking cards, editing customer or card data, and others. Various reports can be made, such as a report on the consumption of a given customer, a report on the use of the customer card, a report on the liquid consumed, etc. The goal of the system is to perform automated dosing of liquid at the customer's request, without the involvement of another person (operator). The choice of liquid, the amount, and the payment of the choice made is fully automatic. Payment is only by card, as in case of an attempt to make a dosage and insufficient availability for payment, the dosage is not carried out. The customer is informed of a small credit on the card. The connection between the machine and the operator display is based on a query from the display. The operator's job involves replacing empty bottles in the machine and monitoring and following up on system irregularities. [ABSTRACT FROM AUTHOR]
