Detailed description of the invention
With reference to accompanying drawing and the embodiment described later that together describes in detail, advantage of the present invention and feature and reach its method will be clear and definite.But, the present invention is not defined in the embodiment of following discloses, but embody with mutually different variforms, the present embodiment is only provided for making of the present invention open more complete, enable the category that general technical staff of the technical field of the invention's easy understand is invented, the present invention only defined by the record of claim.On the other hand, the term used in this specification sheets, for illustration of embodiment, is not really wanted to limit the present invention.In this manual, as long as do not mention especially in sentence, odd number type also comprises complex number type." comprising (comprises) " of using in specification sheets or " (comprising) that comprise ", refer to that inscape, step, action and/or the element mentioned is not got rid of and existed or add other inscapes more than one, step, action and/or element.
Referring to Fig. 3 and Fig. 5, illustrate one embodiment of the invention based on Vehicular battery connect wake control monitor unit and method thereof up.Fig. 3 is the block diagram waking control monitor unit up connected based on Vehicular battery for illustration of one embodiment of the invention, Fig. 4 illustrates for the power supply supply step by Vehicular battery the accompanying drawing waking method for supervising up waking control monitor unit up, and Fig. 5 is the accompanying drawing for illustration of the signal exported in inscape of the present invention.
As shown in Figure 3, of the present invention based on Vehicular battery connect wake up control monitor unit comprise normal power source portion 210, supply disconnecton portion 220, reset circuit portion 230, reset circuit portion 240, with door portion 250, D-trigger unit 260 and micro computer 300.
In the present invention, if supply power supply from Vehicular battery 100, then normal power source portion 210 opens, if normal power source portion 210 opens, then to reset circuit portion 230 input power signal power source (1), that is, power supply 1 accesses, and supply disconnecton portion 220 opens.If supply disconnecton portion 220 opens, then to reset circuit portion 240, with door portion 250, D-trigger unit 260 and micro computer 300 input power signal (power supply 2).That is, power supply 2 accesses.
Illustrate inscape of the present invention further, if from Vehicular battery 100) supply power supply, then normal power source portion 210 opens and out-put supply signal (power supply 1).
If normal power source portion 210 opens, then supply disconnecton portion 220 opens and out-put supply signal (power supply 2).
Reset circuit portion 230 comprises time delay portion 231, if from normal power source portion 210 input power signal (power supply 1), then by time delay portion 231, makes the incoming signal of D-trigger unit 260 (input) carry out time delay by T1 and export.
Reset circuit portion 240 comprises time delay portion 241, if from supply disconnecton portion 220 input power signal (power supply 2), then by time delay portion 241, makes the clock signal of D-trigger unit 260 (clk) carry out time delay by T2 and export.
Wherein, T1 sets be greater than T2.
Power supply signal (power supply 2), the output signal in reset circuit portion 230 and the output signal in reset circuit portion 240 is received with door portion 250, process the reset realized because of the access of car battery power and the reset of opening based on accessory power supply, namely, the process output signal in reset circuit portion 230 and the output signal in reset circuit portion 240, export reset signal (Reset) to micro computer 300.
D-trigger unit 260 as shown in Figure 4, receives power supply signal (power supply 2), incoming signal (input) and clock signal (clk), to micro computer 300 output identification signal (Flag).
Micro computer 300 receives power supply signal (power supply 2), marking signal (Flag) and reset signal (Reset), and with marking signal (Flag) for basis, judgement is waking up based on car battery power access, or waking up based on accessory power supply closedown/unlatching.
With reference to Fig. 5, the action of each inscape of the present invention is described in more detail, when being connected at first with car battery power, namely, if car battery power is supplied to normal power source portion 210 and supply disconnecton portion 220, then normal power source portion 210 and supply disconnecton portion 220 open and output signal are exported as high level.That is, power supply is accessed respectively to reset circuit portion 230 and supply disconnecton portion 220.
Although first reset circuit portion 230 receives output signal (high level signal) (obtaining power supply supply) from normal power source portion 210, but carry out time delay and output signal by T1, so, than to receive output signal (high level signal) (obtaining power supply supply) from supply disconnecton portion 220 and by T2(T2<T1) carry out reset circuit portion 240 time delay T1-T2 time further of time delay, it is high level that signal is exported.
D-trigger unit 260 receives the output signal in reset circuit portion 230 as incoming signal, receives the output signal in reset circuit portion 240 as clock signal, so, if clock signal input, then incoming signal is directly exported as output signal.
In (1), that is, after carrying out time delay by T2, clock signal becomes high level from low level, if input D-trigger unit 260, D-trigger unit 260 directly exports incoming signal (low level signal).Therefore, in (1), the output signal of D-trigger unit 260 is low level.
In (2), that is, after carrying out time delay by T1, incoming signal becomes high level, even if input D-trigger unit 260, because the clock signal of D-trigger unit 260 keeps high level state, so, output signal is directly output as low level.That is, in (2), the output signal of D-trigger unit 260 is low level.
If accessory power supply (ACC) cuts out, then normal power source portion 210 is with opening, and output signal is remained high level, and supply disconnecton portion 220 turns off, and output signal is exported as low level.
Supply disconnecton portion 220 turns off, and reset circuit portion 240 exports output signal as low level, namely, power supply is not supplied from supply disconnecton portion 220, output signal is exported as low level, and D-trigger unit 260 does not supply power supply yet from supply disconnecton portion 220, and output signal is exported as low level.If accessory power supply cuts out, then the output signal of D-trigger unit 260 is low level.
In (3), that is, if accessory power supply is opened, then supply disconnecton portion 220 opens, output signal is exported as high level, reset circuit portion 240 the moment of supplying power supply from supply disconnecton portion 220, makes output signal carry out time delay by T2 and export, and thus exports as low level, after D-trigger unit 260 obtains power supply supply from supply disconnecton portion 220, because clock signal is low level, even if so incoming signal is input as high level, also still output signal is exported as low level.
In (4), that is, after carrying out time delay by T2, reset circuit portion 240 is high level output signal from low level output, because clock signal is input as high level from low level, so D-trigger unit 260 directly exports incoming signal (high level signal) as output signal.That is, accessory power supply is opened and by after T2 time delay, the output signal of D-trigger unit 260 is high level.
The output signal of D-trigger unit 260 is as marking signal input micro computer 300, and micro computer 300, when the marking signal inputted is high level, is judged as waking up based on accessory power supply unlatching.
As previously mentioned, according to the present invention, standby current can be made to reduce, save electric power, particularly can multimedia H/U microcomputer circuit usefully for cutting off the electricity supply.
Above with reference to preferred embodiments and drawings, illustrate with regard to formation of the present invention, but this is example, in the category not surmounting technological thought of the present invention, can various deformation be realized.Therefore, the embodiment that scope of the present invention is not limited to illustrate is determined, not only according to claims, and should should determine according to the scope with this claims equalization.
