Problems solved by technology

[0002] As the price of automobile fuel continues to rise, in order to obtain more profits, some unscrupulous operators of gas stations illegally modify the metering device of the fuel dispenser, so that the actual fuel output of the fuel dispenser is far lower than the nominal fuel output of the fuel dispenser.
At the same time, car owners are paying more and more attention to the amount of fuel refilled each time, always worrying about insufficient refueling at gas stations, and there are two behaviors:
At present, the fuel tanks of automobiles do not have the function of measuring the amount of fuel filled, and the fuel gauge on the dashboard of the car can only roughly measure the amount of remaining fuel in the fuel tank, and cannot measure and display the amount of fuel filled each time in real time
Although the car owner has doubts about the filling volume, but cannot provide accurate evidence, the distrust of the gas station has never been eliminated

Embodiment Construction

[0014] Such as figure 1 The schematic diagram of the module structure of a vehicle refueling recorder is shown, which is installed at the filling port of the fuel tank of the vehicle. An ultrasonic flow sensor is installed in the filling opening of the fuel tank, and an electronic control unit and a display are installed outside the filling opening of the fuel tank. The ultrasonic flow sensor It is connected with the electronic control unit through a signal line, and the electronic control unit is connected with a display through a signal line, and the display is composed of 6-digit seven-segment digital tubes. It also includes an alarm module, the single chip microcomputer is connected with the alarm module, and the alarm module is connected with a loudspeaker.

[0015] The ultrasonic flow sensor is composed of two ultrasonic transducers, a channel switching circuit, a flow transmitting circuit and a flow receiving circuit. The schematic diagram of its working principle is as...

Abstract

The invention belongs to the technical field of refueling metering devices for automobiles, and particularly relates to a refueling recorder for an automobile. The refueling recorder for an automobileis installed at a fuel tank filler of the automobile; an ultrasonic flow sensor is installed in the fuel tank filler; an electronic control unit and a display are installed outside the fuel tank filler; the ultrasonic flow sensor and the electronic control unit are connected through a signal wire; and the electronic control unit is connected to the display through a signal wire. The refueling recorder for an automobile is installed at the fuel tank filler of the automobile, and can display and record the refueling amount of each time in real time, thereby effectively protecting the legitimateinterests of the automobile owners, directly eliminating the consumer distrust of the gas stations and easing the relationship between the two parties.

Description

technical field [0001] The invention belongs to the technical field of automobile refueling quantity metering devices, and in particular relates to an automobile refueling recorder. Background technique [0002] As the price of automobile fuel continues to rise, in order to obtain more profits, unscrupulous operators of some gas stations illegally change the metering device of the fuel dispenser, so that the actual fuel output of the fuel dispenser is far lower than the nominal fuel output of the fuel dispenser. At the same time, car owners are paying more and more attention to the amount of fuel refilled each time, always worrying about insufficient refueling at gas stations, and there are two behaviors. At present, the fuel tanks of automobiles do not have the function of measuring the amount of fuel filled, and the fuel gauge on the instrument panel of the automobile can only roughly measure the remaining fuel amount of the fuel tank, and cannot measure and display the am...
