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.
