Referring to fig. 2, fig. 2 is a schematic structural diagram of a fuel tank switching system according to an embodiment of the present application. The method for switching the fuel tank described below in the embodiment of the present application may be applied to the electronic device shown in fig. 1, and the method includes steps S201 to S203, which are described in detail below:
step S201, if the oil utilization equipment is detected to meet the preset oil tank switching condition, a first control signal is sent to the oil tank switching valve, a first state signal fed back by the oil tank switching valve is received, and the first control signal is used for controlling the oil tank switching valve to switch the current oil supply tank of the oil utilization equipment to a target oil tank.
In this step, the tank switching condition is a condition that satisfies a state of switching the current fuel supply tank to the target tank, the state including, but not limited to, a fuel temperature (hereinafter referred to as an oil temperature), a fuel level (hereinafter referred to as a fuel level), and a fuel type, for example, the oil temperature, the oil level, and the fuel type of the current fuel supply tank, and the oil temperature, the oil level, and the fuel type of the target tank; fuel types include, but are not limited to, high and low congealing point fuels.
Optionally, it is determined whether the oil usage device satisfies a preset tank switch condition based on the oil temperature, the oil level, and/or the fuel type. Illustratively, the oil-using device is exemplified by a vehicle engine, and when the vehicle is driven or started in a non-cold zone environment, the case of meeting the preset oil tank switching condition includes, but is not limited to:
and if the fuel of the current fuel supply oil tank is insufficient, the fuel of the target oil tank is sufficient, and the current fuel supply oil tank is switched to the target oil tank.
And if the current oil supply tank is a low-condensation-point fuel tank, the fuel oil of the high-condensation-point fuel tank is sufficient, and the current oil supply tank is switched to the high-condensation-point fuel tank.
When the vehicle is driving or starting in a cold zone environment, the conditions for meeting the preset fuel tank switching conditions include, but are not limited to:
and if the fuel oil of the current fuel oil tank is insufficient, the fuel oil of the high-condensation-point fuel oil tank is sufficient, and the current fuel oil tank is switched to the high-condensation-point fuel oil tank.
If the fuel of the current fuel supply oil tank is insufficient, the fuel of the high-condensation-point fuel oil tank is insufficient, and the fuel of the low-condensation-point fuel oil tank is sufficient, the current fuel supply oil tank is switched to the low-condensation-point fuel oil tank.
And if the current oil supply tank is a low-condensation-point fuel tank, the fuel oil of the high-condensation-point fuel tank is sufficient and the oil temperature is larger than the preset oil temperature, and switching the current oil supply tank to the high-condensation-point fuel tank.
If the current fuel supply tank is a low-condensation-point fuel tank, the fuel of the high-condensation-point fuel tank is sufficient but the fuel temperature is lower than the preset fuel temperature, and after the fuel of the high-condensation-point fuel tank is heated to be higher than the preset fuel temperature, the current fuel supply tank is switched to the high-condensation-point fuel tank.
It should be noted that, the fuel is sufficient that the fuel level is not lower than the preset fuel level, and the fuel is insufficient that the fuel level is lower than the preset fuel level. It is to be understood that the above case where the tank switching condition is satisfied is only an example given by the present embodiment, and the present application also includes other cases where the tank switching condition is satisfied than the above case.
Optionally, a first status signal fed back by the corresponding fuel feed feedback switch of the fuel tank switching valve is received, where the status signal is used to indicate whether the valve (switch) of the fuel tank switching valve is closed.
Step S202, if the first state signal is a switch-closed signal, after delaying for a first time period, a second control signal is sent to the oil tank switching valve, and the second state signal fed back by the oil tank switching valve is received, wherein the second control signal is used for controlling the oil tank switching valve to switch the current oil return oil tank of the oil utilization device to a target oil tank.
In this step, if the first status signal is a switch-on signal, it is indicated that the fuel supply operation position of the fuel tank switching valve has been switched to a proper position, and at this time, the fuel supply line of the fuel consumption device is changed to a fuel supply line between the target fuel tank and the engine, that is, at this time, the target fuel tank supplies fuel to the engine. When the fuel supply amount of the target fuel tank for supplying fuel to the engine is larger than the fuel consumption of the engine, redundant fuel can flow back to the target fuel tank, and the fuel supply tank and the return fuel tank are synchronously switched during manual switching. However, the oil return process is generally continuous, so that the fuel in the fuel tank before switching is returned to the fuel tank after switching during the switching of the fuel tanks, thereby causing the fuel to be mixed between different fuel tanks and reducing the purity of the fuel.
According to the method and the device, the first time is delayed, so that the oil return oil tank is switched for a period of time after the oil supply tank is switched, the condition that fuel in the oil supply tank before switching flows back to the oil supply tank after switching is reduced, the probability of fuel mixing is effectively reduced, and the purity of fuel is effectively guaranteed.
It will be appreciated that in the embodiments of the present application, the fuel supply path is a path through which fuel in the fuel supply tank is transferred to the engine, and the return fuel path is a path through which excess fuel in the engine is transferred to the return fuel tank.
Alternatively, the first duration may be a preset value or an actual measured value. The actual measurement value is obtained by calculating according to a calculation formula according to the fuel amount in the original fuel supply oil way, the fuel consumption speed and the fuel return speed of the engine, wherein the calculation formula can be as follows: actual measurement duration = fuel quantity in the original fuel line/(fuel consumption speed of engine + return speed). It can be understood that the actual measurement value is taken as the first time length, so that the condition that fuel in the fuel supply tank before switching flows back into the fuel supply tank after switching can be effectively reduced, the condition that fuel in the fuel supply tank after switching flows back into the fuel supply tank before switching can be effectively reduced, and the probability of fuel mixing is further reduced.
In step S203, if the second status signal is the switch-on signal, the switching of the oil tank of the oil-using device is completed.
In the step, if the second state signal is a switch closed signal, the oil return working position of the oil tank switching valve is switched to be in place, and at the moment, an oil return oil way of the oil utilization device is changed to an oil return oil way between the engine and the target oil tank, namely, at the moment, the oil supply oil way and the oil return oil way form a complete circulating oil way, and the oil tank switching is completed.
With reference to figure 3 of the drawings, fig. 3 is a schematic structural diagram of a tank switching system according to another embodiment of the present disclosure. As shown in fig. 3, the embodiment of fig. 3 further includes steps S301 to S302 after the above step S101, on the basis of the embodiment of fig. 2. It will be appreciated that the same steps as in fig. 2 are not repeated here.
Step S301, if the first status signal is a switch non-closed signal, entering a first fault detection step, where the first fault detection step includes: and after the second time interval, sending the first control signal to the oil tank switching valve again, and receiving a third state signal fed back by the oil tank switching valve each time.
In this step, if the first status signal switch is not turned on, it indicates that the oil supply operation position of the oil tank switching valve is not switched in place, and at this time, the oil supply line of the oil usage device may be the original oil supply line, that is, the oil tank switching may have a fault, so that the first fault detection step is used for checking. In order to avoid the fuel mixing caused by direct switching of the fuel paths due to incorrect feedback of the fuel feed feedback switch, the fuel control method and device send the first control signal to the fuel tank switching valve again after delaying the second time length, and receive the third state signal fed back by the fuel tank switching valve.
Optionally, the second duration may be a preset value or an actual measurement value, and the measurement principle thereof may refer to the measurement process of the first duration, which is not described herein.
Step S302, if all the third status signals are switch-off signals and the number of times of sending the first control signals reaches the first preset number of times, determining that the oil tank switching failure occurs in the oil consumption equipment.
In this step, when the oil supply operation position of the oil tank switching valve is not switched to be in place after a plurality of times of fault detection, the abnormality of the oil tank switching is described. For example, the first preset times are 3 times, when the first fault detection step is performed for 3 times, and the third state signals received by the 3 times are all switch-off signals, the switching faults of the oil supply tank of the oil equipment are judged, and the fault signals are fed back to the display unit so as to remind a user, so that the intelligent degree of the switching mode of the oil tank is further improved.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a tank switching system according to another embodiment of the present disclosure. As shown in fig. 4, the embodiment of fig. 4 further includes steps S401 to S402 after the above step S102, on the basis of the embodiment of fig. 2. It will be appreciated that the same steps as in fig. 2 are not repeated here.
Step S401, if the second status signal is a switch non-closed signal, entering a second fault detection step, where the second fault detection step includes: and after the second time interval, sending a second control signal to the oil tank switching valve again, and receiving a fourth state signal fed back by the oil tank switching valve each time.

In order to avoid the fuel mixing caused by direct switching of the fuel paths due to feedback errors of the return feedback switch, the method and the device send a second control signal to the fuel tank switching valve again after delaying the second time length, and receive a fourth state signal fed back by the fuel tank switching valve.
Step S402, if all the fourth status signals are switch-off signals and the number of times of sending the second control signals reaches the second preset number of times, determining that the oil tank switching failure occurs in the oil consumption equipment.
In this step, when the oil supply operation position of the oil tank switching valve is not switched to be in place after a plurality of times of fault detection, the abnormality of the oil tank switching is described. For example, the second preset times are 3 times, when the first fault detection step is performed for 3 times, and the fourth state signals received by the 3 times are all signals with the switch not closed, the switching fault of the oil return tank of the oil equipment is judged, and the fault signals are fed back to the display unit so as to remind a user, so that the intelligent degree of the switching mode of the oil tank is further improved.
Referring to fig. 5, fig. 5 shows a schematic structural diagram of a tank switching system according to still another embodiment of the present application. As shown in fig. 5, the embodiment of fig. 5 further includes steps S501 to S503 before the above step S101, on the basis of the embodiment of fig. 2. It will be appreciated that the same steps as in fig. 2 are not repeated here.
In step S501, if the fuel level of the current fuel supply tank is lower than the first preset level, and/or the current fuel supply tank is a low condensation point fuel tank, the fuel temperature of the target fuel tank is obtained, and the target fuel tank is a reserve fuel tank storing high condensation point fuel.
In this step, the first preset liquid level may be a preset fixed value, or may be a preset variation value adjusted based on the external environment temperature. For example, the first preset liquid level may be preset to a higher value when the ambient temperature is low, and the first preset liquid level may be preset to a lower value when the ambient temperature is high. For example, the first preset liquid level is 30% when the ambient temperature is 0 ℃, and the first preset liquid level is 5% when the ambient temperature is 30 ℃. The first preset liquid level may also be a preset variation value based on the liquid level adjustment of the reserve tank, for example, the first preset liquid level may be 30% when the oil level of the reserve tank is greater than 50%, and the first preset liquid level may be 5% when the oil level of the reserve tank is less than 30%, i.e., the oil level of the reserve tank is proportional to the first preset liquid level.
It should be understood that the above-mentioned setting manner of the first preset liquid level is only used as an example, and other embodiments may also be other manners, for example, the first preset liquid level may also be a preset variation value that is adjusted together based on the external environment temperature and the oil level of the reserve oil tank, which is not described herein.
Step S502, if the fuel temperature is greater than the preset temperature, judging that the fuel consumption equipment meets the fuel tank switching condition.
In the step, the preset temperature is the lowest oil supply temperature of the high-condensation-point fuel, and the oil temperature of the target oil tank is detected to ensure that the target oil tank can be used in the current temperature environment, so that the high-condensation-point fuel is prevented from being solidified to block an oil supply path.
In step S503, if the fuel temperature is not greater than the preset temperature, the fuel heating device is controlled to heat the fuel with high condensation point in the target fuel tank, and when the fuel temperature of the target fuel tank is not less than the preset temperature, it is determined that the fuel consumption device meets the fuel tank switching condition.
In this step, the fuel heating device may be a fuel heating resistance wire. The fuel oil with the high condensation point is heated to realize the fuel oil supply by adopting the fuel oil with the high condensation point preferentially, so that the fuel oil cost is reduced.
Optionally, for the oil-using equipment that is running, when external environment temperature is lower, first preset liquid level is higher value, then can reserve the heating time for high congeal point fuel, when guaranteeing that oil-using equipment needs the switching oil tank in the operation process, can preferentially adopt low-cost high congeal point fuel, guarantee simultaneously that oil-using equipment is safe to operate.
Alternatively, for the oil-using device to be started, the oil-using device may be restarted after the high-condensation-point fuel is heated to not less than the preset temperature and the current fuel tank is switched to the high-condensation-point fuel tank. The current oil supply tank can be switched to the low-condensation-point fuel tank, the oil utilization equipment is started, and when the high-condensation-point fuel is heated to be not less than the preset temperature, the current oil supply tank is switched to the high-condensation-point fuel tank.
In one embodiment, the target fuel tank is a high-freezing point fuel tank with a highest fuel level of a plurality of reserve fuel tanks having a fuel level greater than a second predetermined level. The first preset liquid level is less than the second preset liquid level.
In this embodiment, by detecting the oil levels of all the spare oil tanks storing the high-condensation-point fuel oil, a plurality of spare oil tanks with oil levels greater than the second preset liquid level are screened, and then the oil levels of the plurality of spare oil tanks are compared, and the spare oil tank with the highest oil level is marked as the target oil tank. Therefore, the oil tank switching frequency is effectively reduced while the cost is reduced, and the risk of accidents caused by oil tank switching in the operation process of the oil utilization equipment is reduced.
In an embodiment, the method further comprises: detecting a fuel level change value of a current fuel supply tank in a third duration; and if the fuel level change value is larger than the preset change value or the fuel level change value is 0, sending a fault signal to the target display unit.
In this embodiment, the liquid level change of the oil usage apparatus at the time of operation and at the time of standby can be detected. The fault conditions corresponding to the fault signals comprise oil leakage of the oil tank, fault of the liquid level sensor or oil theft.
When the oil consumption device is in operation, if the detected change value of the fuel oil level is larger than the preset change value, the abnormal oil consumption speed of the oil consumption device is indicated, and the oil leakage of the oil tank or the fault of the fuel oil level sensor can occur.
When the fuel consumption apparatus is in operation, a fuel level change value of 0 is detected, and a malfunction of the fuel level sensor may occur.
When the oil utilization device is in standby, the condition that the oil tank leaks oil or is stolen can occur if the change value of the fuel oil level is detected to be larger than the preset change value.
In an embodiment, the method further comprises: before the oil utilization device is started, if the difference between the current fuel temperature of the fuel supply tank and the ambient temperature is larger than a preset difference, a fault signal is sent to the target display unit.
In this embodiment, for example, when the remote control unlocking signal sent by the BCM is collected, the external environment temperature (sent by the air conditioner controller through the CAN bus) and the fuel temperature are collected at the same time, if the difference value between the external environment temperature and the fuel temperature is greater than a set value, a fault signal is sent to the meter, and after the vehicle is powered on, the meter prompts the driver to detect whether the fuel temperature sensor is faulty.
In an embodiment, when the oil using device is running, the oil temperature of the current oil supply tank is monitored in real time, and if the oil temperature exceeds a set value, a fault signal is sent to the display unit so as to remind a user.
