An automatic water vending device relates to commercial equipment and intended for automatic dispensing of fresh water in locations close to consumers, wherein either foreign water or additionally treated tap water are used for distribution.The inventive essence is characterized in that the device comprises an electronic unit connected to a microcontroller providing reception and reading electronic and/or magnetic cards with subsequent asset thereof, or electronic identifiers allowing to determine the account positive balance and the microcontroller serving as water gauge, control unit and accounting device.A shutoff valve at the vending device outlet is of an electronic type opened and closed by a signal formed by the microcontroller by subsequent signals aggregate:- from an electromagnetic sensor fit into the water pipe, or water level meters in the water storage tank;- signals from water level meters depending on the water storage tank filling;- information signals, read from the electronic and/or magnetic cards, or electronic identifiers allowing to determine the account positive balance;- control signals received from the distribution center provided that the vending device is connected thereto.Use of the microcontroller in the automatic water vending device makes it possible to carry out automated registration and control of water consumption and amount of payment. The automatic water vending device owner can compile full automated sale accounts. There can be formed automated trading network via an outer communication line, the trading network comprises a plurality of the vending devices, assigning the identification number to each of them, thus providing tracing operation of all devices and in emergency cases to remote switching. |
