Smart fuel dispenser control board PCBA

The intelligent fuel dispenser control board PCBA is the core component of the fuel dispenser, which is used to accurately control the fueling process and realize various intelligent functions. The following is its introduction:

Hardware composition

• Main control chip: Generally adopts a high-performance microcontroller with powerful computing power and rich interfaces, responsible for coordinating the work of various parts of the control board, processing various input signals, and outputting control instructions according to the preset program.

• Display module: Usually composed of a liquid crystal display (LCD) or a light-emitting diode display (LED) and its driving circuit, used to display the amount of fuel, the amount, the oil product information, etc.

• Keyboard input module: including a membrane keyboard or a touch keyboard, which is convenient for operators to enter fueling parameters, such as the amount of fuel, the amount of fuel, etc.

• Metering module: composed of a flow sensor and a metering chip. The flow sensor detects the flow of the oil in real time. The metering chip converts the sensor signal into the fueling amount data and transmits it to the main control chip.

• Communication module: supports multiple communication protocols, such as RS-485, CAN bus, etc., for data transmission with the management system of the gas station to achieve remote monitoring and management.

• Power module: converts the input AC power into stable DC power required by various parts of the control board, usually with overvoltage and overcurrent protection functions to ensure stable operation of the control board.

• Drive module: used to drive the motor, valve and other actuators of the fuel dispenser, and control the oil output and oil output speed of the fuel dispenser according to the instructions of the main control chip.

Working principle

• When the operator enters the refueling parameters through the keyboard, the main control chip controls the drive module according to the set value, drives the motor to drive the oil pump, and opens the corresponding valve at the same time, so that the oil flows through the pipeline to the fuel dispenser. The metering module monitors the oil flow in real time and feeds the data back to the main control chip. The main control chip calculates the refueling amount and amount based on the flow data, and displays it in real time through the display module. During the refueling process, the main control chip will also upload the refueling data to the gas station management system through the communication module. When the set refueling amount or amount is reached, the main control chip issues a command to close the valve and stop refueling.

Functional features

• Accurate metering: using high-precision flow sensors and advanced metering algorithms to ensure high metering accuracy of the refueling amount and error control within the specified range.

• Intelligent control: It has a variety of intelligent functions, such as quantitative refueling, non-quantitative refueling, oil product switching, etc., which can be flexibly set according to user needs.

• Safe and reliable: It has multiple safety protection mechanisms, such as overcurrent protection, overvoltage protection, leakage protection, etc., to ensure the safe operation of the fuel dispenser.

• Powerful communication function: It supports multiple communication methods, which is convenient for seamless connection with gas station management system, payment system, etc., to realize information management.

Application field

• It is mainly used in various gas stations, including traditional fuel gas stations and new electric vehicle charging stations (in electric vehicle charging stations, the principle is similar, but the object of control becomes charging equipment). In gas stations, it is a key component for realizing the automation and information management of refueling operations, which can improve refueling efficiency and service quality, and provide accurate data support for the operation and management of gas stations.
