TH20567U - Coin-operated drinking water vending machines with a built-in water quality measuring device (TDS). - Google Patents

Abstract

Coin-operated drinking water vending machine with a TDS water quality measuring device installed. Its main components include a central processor for receiving external commands to process the received commands. Part of the central processor is connected to the water level measurement unit and receives signals from the money receiving slot and receives connections from the TDS meter. It is connected to the display screen and is connected to the water dispensing pump and is connected to the dispensing and stopping buttons. It is connected to the Flow Meter and is connected to the data receiving and sending unit with a SIM card connected and connected to the machine's server to collect data via GPRS or to help send and receive data to an external server to collect data via GPRS so that consumers can receive clean drinking water. This invention therefore measures and displays the TDS value on the screen of the coin-operated drinking water vending machine. If the measured TDS value exceeds the set value, the central processor (1) will process to stop the operation of the drinking water vending machine and display a warning message on the display screen (5), which means the drinking water vending machine will not be able to accept money from customers and will not be able to sell drinking water. The machine's server (10) or an external server (11) will send an SMS warning by ordering through the central processor (1).

Claims (1)

A coin-operated water dispenser with a TDS water quality measurement device installed consists of a central processing unit (1) which is a device with an internal instruction unit that can operate with the power supplied to it, receiving external instructions to process the received instructions and then sending the processed instructions to other connected parts. Part of the central processing unit (1) is connected to the water level measurement unit (2) in the water storage tank of the coin-operated water dispenser to know the water level in the tank. Another part of the central processing unit (1) is connected to the money receiving slot (3) to know the amount of money the customer has inserted in coins or banknotes. Another part of the central processing unit (1) is connected to the display screen (5), which is a display unit that can operate with the power supplied to it and receives instructions sent from the central processing unit (1) to display the amount of water and the amount of money corresponding to the amount of coins or banknotes the customer has inserted. Another part of the central processing unit (1) is connected to the dispensing and stopping button (6) to issue an instruction to dispense water in the amount of money the customer has inserted in coins or banknotes. In accordance with the amount displayed on the display screen (5), another part of the central processing unit (1) is connected to the water pump (7) to supply water in accordance with the amount displayed on the display screen (5), and another part of the central processing unit (1) is connected to the Flow Meter (8) to measure the amount of water sold from the water dispenser, and another part of the central processing unit (1) is connected to the input/output unit (9) which is a device that is connected to receive and transmit data between the central processing unit (1) and the input/output unit (9), and the input/output unit (9) can have a server of the machine (10) which is a computer or operating system that provides one or more services to at least one computer or operating system connected to it by a server connector for connecting to receive and transmit data to the central processing unit (1) or the input/output unit (9) can connect to at least one external server (11) by an external server connector which is used to connect between the machine's server (10) and the external server (11) for connecting to receive and transmit data from The external data is transmitted to the central processor (1). It has a special characteristic: the central processor (1) is connected to the payment slot (3), the TDS meter (4), and the display screen (5) to show the amount of water and the amount of money corresponding to the number of coins or banknotes the customer inserts, and to show the TDS value of the water as measured by the device. The central processor (1) is connected to the data transmission unit (9) which has a connected SIM card (12), which is a SIM card of at least one network provider, which can connect directly or multiplexed to help transmit data between the data transmission unit (9) and the machine's server (10) via GPRS or to help transmit data to an external server (11) via GPRS. In the event that the measured TDS value exceeds the set value, the central processor (1) will process to stop the operation of the water dispenser and display a warning message on the display screen (5), which means the water dispenser will not be able to accept money from customers and will not be able to Drinking water dispenser and machine server (10) or external server (11) will send SMS alerts by ordering through the central processor (1).
