Based on above-mentioned, under situation/condition that host side device 100 and resident family's terminal installation 200 do not carry out communication (namely, intercommunication is not carried out) between host side device 100 and resident family's terminal installation 200, owing to adopting waking instruction WKS up and can't be applied in pulse-width modulation signal, so P-type crystal pipe QP and N-type transistor QN can close (OFF), to such an extent as to power bus 300 now only can transmit input power P
iN(=FV) uses to resident family's terminal installation 200.
In addition, under situation/condition that host side device 100 and resident family's terminal installation 200 will carry out communication (namely, intercommunication will be carried out) between host side device 100 and resident family's terminal installation 200, owing to adopting waking instruction WKS up and can be applied in pulse-width modulation signal, to such an extent as to P-type crystal pipe QP and N-type transistor QN can react on and wakes instruction WKS up and synchronously conducting (ON) or close (OFF).Add, the voltage SV (=+ 12V) of the second DC power supply is greater than the cause of the voltage FV (=+ 7V) of the first DC power supply, so the instruction WKS that wakes up be applied in is loaded in the input power P that power bus 300 transmits
iNon (that is, DC power supply FV).Now, power bus 300 transmits to be loaded with the input power P waking instruction WKS up
iN.
With this understanding, namely detection line 205 can detect and wake instruction WKS up (namely from power bus 300, pulse-width modulation signal), to make microprocessing unit 207 react on waking instruction WKS up and wake normality up and be in resident family's terminal installation 200 under resting state detected by detection line 205, thus host side device 100 and resident family's terminal installation 200 is made to carry out communication/call.Meanwhile, power conversion unit (that is, 201 and 203) can't be subject to detection line 205 impact and in the same manner as can provide/produce working power P needed for resident family's terminal installation 200 built-in function
oP.Apparently, host side device 100 can by single power supply bus 300 to transmit power supply (P
iN) use to resident family's terminal installation 200, and can transmit and wake instruction (WKS) up and wake the resident family's terminal installation 200 be under resting state up.
In sum, the host side device 100 in the security protection surveillance 10 carried of the present invention and the power bus 300 that draws between resident family's terminal installation 200 are except in order to transmit power supply (P
iN) outward, it more can transmit and wake instruction (WKS) up and wake the resident family's terminal installation 200 be under resting state up.In other words, the enforcement concept given by the present invention is the power supply (P for transmitting in single power supply bus 300
iN) upper loading wakes instruction (WKS) up.Thus, host side device 100 namely can by single power supply bus 300 to transmit power supply (P
iN) use to resident family's terminal installation 200, and can transmit and wake instruction (WKS) up and wake the resident family's terminal installation 200 be under resting state up.Thus, because only single power supply bus 300 need be drawn between host side device 100 and resident family's terminal installation 200, so the present invention not only can simplify the wiring quantity between host side device 100 and resident family's terminal installation 200, and then reduction wiring cost, debug mode even therebetween also can become relatively simple and easy.
In addition, it is worth mentioning that, as long as suitably change the responsibility cycle of pulse-width modulation signal waken up corresponding to instruction (WKS) and/or the words of frequency, then can realize other functions being different from arousal function, such as: text broadcast message informing, sound radio message informing, image broadcast notice, dangerous information warning notice ... Deng, but be neither limited to this, all are discussed depending on actual design/application demand.
Although the present invention discloses as above with above-mentioned one exemplary embodiment; so itself and be not used to limit the present invention; have in any art and usually know the knowledgeable; without departing from the spirit and scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is when being as the criterion of defining depending on included right.
In addition, any embodiment of the present invention or claim must not reach whole object disclosed by the present invention or advantage or feature.In addition, summary part and title be only used to auxiliary patent document search with, be not used for limiting interest field of the present invention.
