Only come into force after single-chip microcomputer have sent #RST signals, after vibration, Q ends output low level is detected, pull-up is closed automatically
Close, so as to reduce further the power consumption of system.
Brief description of the drawings
The low-power consumption vibration detection circuit figure that Fig. 1 provides for the utility model embodiment.
The improved low-power consumption vibration detection circuit figure that Fig. 2 provides for the utility model embodiment.
Embodiment
For ease of skilled artisan understands that technology contents of the present utility model, below in conjunction with the accompanying drawings to the utility model
Content is further explained.
The utility model passes through as shown in figure 1, the technical solution of the utility model is：Low-power consumption vibration detection circuit, bag
Include：D type flip flop, switch, power supply, resistance, diode；The CLK ends of the d type flip flop are connected with resistance first end, and CLK ends are instant
Zhong Duan, the end of resistance second and d type flip flopEnd is connected,Remove end in end；The Q ends and two of the d type flip flop
Pole pipe negative pole is connected, and the diode cathode detects the output of circuit as low-power consumption；D type flip flopEnd is used as low-power consumption
The input of circuit is detected,End is preset end；The resistance is also connected as pull-up, its second end with positive source；It is described
Resistance first end is also connected with switch first end, the second end of switch ground connection；The D ends ground connection of d type flip flop；Power cathode connects
Ground；The d type flip flopEnd is hanging.
As shown in figure 1, D1 is with asynchronous removing and prefabricated d type flip flop, d type flip flop here is those skilled in the art
Known electronic component, is not described in detail in this application, and switch S1 switchs for vibration detection, including but not limited to water
Silver-colored vibroswitch, spring vibration switch, rolling ball vibration switch etc..Resistance R1 is pull-up resistor.Diode V1 is formed to single-chip microcomputer
Open-drain output interface.
The technology contents of the application can be more clearly understood for those skilled in the art, the now low-power consumption to the application is vibrated
The operation principle of detection circuit is described below：
First, single-chip microcomputer exports the low level signal #RST of a period of time to initialize detection circuit；After the completion of initialization,
The Q ends output high level of d type flip flop, diode cathode #Out ends are high resistant free state；When equipment is vibrated, vibration inspection
Slowdown monitoring switch S1 forms several pulses in the presence of pull-up resistor R1 on the CLK ends of d type flip flop, and rising edge therein will
D type flip flop is triggered, the low level signal at d type flip flop D ends is latched into the Q ends of d type flip flop, diode cathode is that #Out ends are changed into
Low level, single-chip microcomputer is that may detect that to be vibrated.
Because circuit power consumption is extremely low, the reserve battery that can use of the application works, and power supply is dry cell or lithium electricity
Pond etc., thus the application to the detecting of vibration independent of main-system part, before single-chip microcomputer resends #RST signals, hair
The vibration given birth to will make #Out ends keep low level state, it is achieved thereby that the function #RST signals of vibration occurred for " remembeing " i.e.
Reset signal,.
