Be illustrated in figure 1 as lasting monitoring fuel tank oil mass process chart,
The vehicle management person at first opens switch and sets reception display alarm display format, when anti-fluctuation electronic type fuel level sensor detects the oil reserve variation and is converted into electric signal, send signal to the electron steering projector then, electron steering transmitter receipt and processing signals, after reception display alarm reception electron steering projector sends signal, can realize uninterruptedly showing the oil mass of fuel tank, display mode and the specified surplus alarm display of certain intervals time also can be set, can realize that the fuel tank oil mass continues monitoring.
Be illustrated in figure 4 as the instruction repertorie schematic flow sheet under this mode of operation, the oil mass watchdog routine begins the back operating switch, sets timing; The anti-fluctuation of electron steering projector collection electronics fuel level sensor signal carries out oil mass and stores; If timing continues to gather anti-fluctuation electronics fuel level sensor signal less than, electron steering projector, carry out oil mass and store; After timing arrived, the electron steering projector sent metering signal, received display alarm and showed oil mass; Then operating switch repeats said procedure again.
Be illustrated in figure 2 as the process chart that oil consumption is carried out automatic gauge,
The vehicle management person at first opens switch and sets quantitative model, when anti-fluctuation electronic type fuel level sensor detects the oil reserve variation and is converted into electric signal, the vehicle management person passes through self-learning function, record mileage number and time number, the corresponding relation of calculating and oil consumption sends signal to the electron steering projector, electron steering transmitter receipt and processing signals then, receive display alarm and receive the electron steering projector and send signal, so just realized that oil consumption carries out automatic gauge.
Be illustrated in figure 6 as the instruction repertorie schematic flow sheet under this mode of operation, the automatic gauge program begins the back operating switch, sets timing or mileage at interval; The signal that electron steering projector collection anti-fluctuation electronics fuel level sensor and car speed sensor send carries out mileage and oil consumption corresponding relation and calculates and store; If timing or mileage at interval less than, the electron steering projector continues to gather anti-fluctuation electronics fuel level sensor signal, proceeds that mileage and oil consumption corresponding relation calculate and storage; Timing to or after mileage arrived, the electron steering projector sent mileage and oil consumption corresponding relation metering signal, receives display alarm and shows oil mass; Then operating switch repeats said procedure again.
Monitor or warn the process chart that the fuel tank oil reserve changes as shown in Figure 5.The vehicle management person at first opens switch and sets alarm mode, anti-fluctuation electronic type Shan level sensor detects the oil reserve variation and is converted into electric signal, electromagnetic flow transducer on oil outlet pipe, the oil return pipe detects the oil mass variation and transforms electric signal, engine speed sensor detection of engine rotating speed on the driving engine is converted into electric signal, automatically the mileage number signal is measured in study, each sensor signals is all sent signal to the electron steering projector then, electron steering transmitter receipt and processing signals receive display alarm reception electron steering projector and send signal.If oil reserve changes unusually in the fuel tank, oil outlet pipe and oil return pipe oil mass variation abnormality do not turn round or do not have when existing oil mass to reduce under the situation of mileage number to occur at driving engine, and the present invention will send alerting signal and preserve concrete the variation; The present invention also sends alerting signal during by non-permission dismounting; After receiving the display alarm reception, show related data and warning.
Fig. 8 is the instruction repertorie schematic flow sheet under this mode of operation, the emergent alarm program begins the anti-fluctuation of electron steering projector collection electronics fuel level sensor, unusually whether detect oil mass unusual, if it is unusual, the electron steering projector is waken up, gather signal that engine speed sensor signal, car speed sensor send, gather anti-fluctuation electronics fuel level sensor signal and go out, the signal of oil return pipe electromagnetic flow transducer; Determine whether vehicle ' or engine running have problem,, receive display alarm display alarm signal if after having problem electron steering projector to send alerting signal; Then operating switch repeats said procedure again.
Between electron steering projector of the present invention as shown in Figure 7 and the reception display alarm, can realize the wireless telecommunications of certain frequency scope, except that transmitting alarm message and related data, receiving display alarm can be provided with electron steering wireless launcher mode of operation.
Working process of the present invention:
1. during vehicle stationary state (judging this state) by Vehicular system system power supply or vehicle speed signal, and not starting of driving engine.The present invention directly uses storage battery as power supply, and is in running order.Because driving engine does not turn round, and should not have variation that should not have oil reserve in fuel flow amount and the fuel tank in the fuel pipe, the electron steering projector sends normal state signal after the signal that receives is handled, and receives display alarm and shows " normally "; As oil reserve in the fuel tank change or fuel pipe in the fuel flow amount is arranged, after then the electron steering projector is handled the signal that receives, send the abnormal state signal, display alarm shows " mal ";
2. vehicle start (judging this state by Vehicular system system power supply or vehicle speed signal) is preceding, and driving engine starts.Because engine running, the variation that the oil reserve of certain limit should be arranged in the fuel flow amount of certain limit and the fuel tank should be arranged in the combustion Shan pipe, after the electron steering projector is handled the signal that receives, as belong in the normal range, then send normal state signal, display alarm shows " normally "; As the variation of oil reserve in the fuel tank or the fuel flow amount in the fuel pipe, after the electron steering projector is handled the signal that receives, as belong in the mal scope, then send the abnormal state signal, display alarm shows " mal ";
3. after the vehicle '.Because engine running, the variation that the oil reserve of certain limit should be arranged in the fuel flow amount of certain limit and the fuel tank should be arranged in the fuel pipe, after the electron steering projector is handled the signal that receives, as belong in the normal range, then send normal state signal, receive display alarm and show " normally "; As the variation of oil reserve in the fuel tank or the fuel flow amount in the fuel pipe, after the electron steering projector is handled the signal that receives, as belong in the mal scope, then send the abnormal state signal, display alarm shows " mal ";
In order to protect main car electric system, the consumption of current of storage battery limits within the specific limits, and the present invention is under the non-operative condition of driving engine; the present invention takes to be interrupted mode of operation, and by starter control end signal, when main car starts; cut off supply line of the present invention, prevent the storage battery overload.
For guaranteeing safety, design built-in power in the electron steering projector, stationary vehicle, when Vehicle Power turn-offed, the electron steering projector passed through built-in power, be in the standby low-power consumption, during the oil mass sudden change, wake controller work up, finish data logging, carry out the emission of signal alarm and related data in case of necessity, notify the supvr.
