Problems solved by technology

[0002] The existing conventional automobile fuel tank liquid level measurement device generally uses a float to drive a curved rod to change the resistance value of the marking line into a current signal, and drives a traditional pointer type oil level gauge to achieve a relatively low display accuracy for the driver to roughly estimate the oil volume. , this method cannot accurately manage the oil volume, and cannot prevent the occurrence of oil theft and oil spills; energy shortages and high oil prices have caused some transportation companies to use oil dipsticks for manual operation, but the labor intensity is high and the method is backward, which is not suitable for current technology Development of requirements for monitoring and management of oil consumption
[0003] In addition, a high-precision liquid level gauge is installed in the fuel tank to improve the measurement accuracy, but this transformation method is difficult to implement on site: 1. Remove the original low-precision sensor and directly replace it with a new high-precision sensor, resulting in the original vehicle instrumentation Incompatibility; 2. For the modification of the fuel tank to increase the fuel port, the vehicle must be stopped for business, the fuel tank should be emptied to store fuel, the fuel tank should be removed, the residual oil should be evaporated with steam, and the fuel tank should be inspected to see if there is any residual fuel. Open a hole with gas welding at a suitable position above the fuel tank, remove the residue in the fuel tank, weld the flange, inspect the welding quality, fill the fuel tank with two-component anti-rust paint, paint the outside of the tank with anti-rust paint, and install a high-precision liquid level gauge , and then enter the steps of fuel volume calibration and fuel volume measurement, etc. It is very complicated, not to mention that the vehicle is running and operating, and it cannot take a long pause to wait for you to modify the fuel tank, so it is almost impossible to implement the modification of the crude oil tank. In short, existing vehicles Unable to implement accurate automatic measurement, record, monitoring and management of oil quantity

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The measurement signal of the high-precision liquid level sensor is input to the display device, and

[0016] Below in conjunction with accompanying drawing, the present invention will be further described:

[0017] As shown in Figure 1, a precision metering container device for an externally connected fuel tank of a vehicle includes a display device and a fuel tank 3. It is characterized in that the fuel tank 3 is externally connected to a metering container 1, and a high-precision liquid level is set in the metering container. Sensor 6, the bottom of the metering container communicates with the oil outlet at the bottom of the fuel tank 3 through a connecting pipe 2; the measurement signal of the high-precision liquid level sensor is input to the display device, which can be monitored by a GPS monitoring device with wireless communication function Remote transmission to the computer information management platform. The...

Abstract

The invention discloses a external vehicles fuel tank oil mass precise measurement vessel installment, which including the display unit, the fuel tank, which characteristic is, the states fuel tank exterior connects measurement vessel, the high accuracy fluid position sensor installs in this measurement vessel, the states measurement vessel base and the fuel tank base fuel oil outlet connects through a connecting pipe. The external pod because of the small volume and the damping action of the connecting pipe is advantageous to keep the liquid meter float stability and balance, moreover after with the external pod, the actual biggest storing oil mass is bigger than the original fuel tank, and has overcome the original instrument incompatible flaw. The invention with simple structure, the fast convenient installment, is extremely suitable to fast implement the high accuracy oil mass survey record monitoring the scientific management under no change the automobile original fuel tank structure and the sensor measuring appliance electric circuit premise.

Description

technical field [0001] The invention relates to a vehicle fuel tank oil volume metering device, in particular to an externally connected precision metering container device for the vehicle fuel tank oil volume. Background technique [0002] The existing conventional automobile fuel tank liquid level measurement device generally uses a float to drive a curved rod to change the resistance value of the marking line into a current signal, and drives a traditional pointer type oil level gauge to achieve a relatively low display accuracy for the driver to roughly estimate the oil volume. , this method cannot accurately manage the oil volume, and cannot prevent the occurrence of oil theft and oil spills; energy shortages and high oil prices have caused some transportation companies to use oil dipsticks for manual operation, but the labor intensity is high and the method is backward, which is not suitable for current technology Develop requirements for oil consumption monitoring and...
