In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the circuit connection diagram of the utility model state converter embodiment.
Accompanying drawing marks: 1, time delay module; 2, level is become a cadre contact module.
Embodiment
With reference to Fig. 1, the utility model state converter embodiment is described further.
But the utility model can realize in various different formats, and the utility model should not be construed as and is limited to exemplary embodiment set forth herein.There is provided exemplary embodiment to contribute to more fully understanding the utility model.
As shown in Figure 1, a kind of state converter, comprises time delay module, receives extraneous detection signal, extends the detection signal time by timing chip; Level is become a cadre contact module, receives the detection signal after extending, by relay dry contact conversion output alarm signal.
Time delay module comprises signal input interface, 555 chips, and signal input interface J2 is the signal input part of plugging mode, and it receives the signal of vibration transducer module.It is provided with three bars transmission branches altogether, be respectively low and high level signal, detection signal, ground signalling from top to bottom, its operational pin is 2 pin, in normal state, 2 pin signals are high level, vibration transducer module occur vibration time, 2 pin become low level signal, and signal sends into IC1(i.e. 555 chips after filter capacitor C5 and filter resistance R4 filtering) input pin.The direct clearing pin of 555 chips also couples with signal input interface, receives its high and low level signal.
555 chip height trigger pin and electric discharge pin are connected on protection electric capacity (being also timing capacitor) C2 simultaneously, and input pin is high level at ordinary times.
Because input pin is high level, inner discharge tube conducting, the conducting over the ground of electric discharge pin, the voltage on electric capacity C2 is 0V, and high trigger pin is also 0V, and chip exports and is always low level state.When vibration transducer module exports vibration signal, input pin becomes low level from high level, and during this low level <1/3VCC, the output terminal of 555 chips reverses, the output of output pin becomes high level by low level, meanwhile, the discharge tube cut-off of 555 chip internals.Power supply is charged to C2 by R2.Through after a while, as voltage >2/3Vcc on C2, output circuit reverses, the output of output pin becomes low level from high level, discharge tube conducting, C2 is by the electric discharge pin rapid discharge of timing chip, and time delay module gets back to again original stable state.
Therefore, when the input pin input of 555 chips has a low level, the output pin of 555 chips time delay will export a high level.
555 chips, R2, C2 form delay monostable multivibrator circuit, can ensure the impact of circuit interference-free trigger pulse within the temporary stable state duration.R2 can be a slide rheostat, by the width regulating the resistance of R2 to carry out regulation output pulsewidth, thus can arrange the time of time delay.
Level contact module of becoming a cadre comprises indicator unit DS1, relay module K1 and output switch parameter interface J1.
Indicator unit adopts light emitting diode DS1, and its one end connects the output pin of 555 chips, other end ground connection, and this pilot lamp is for showing the vibration signal state of vibration transducer module transfer.
Relay module comprises coil and some contacts, coil coupling in the output pin of 555 chips, for receiving the output signal of 555 chips, thus pilot relay action.When 555 chips export high level signal, drive relay K 1 action, now, the state of dry contact overturns, and the NO(of relay often opens) closed, produce warning dry contact signal.The warning dry contact signal produced is exported by output switch parameter interface.Output switch parameter interface comprises power branch and the GND branch road of+12, and power branch couples input pin and the external power supply pin of 555 chips by diode D2 and R3.
Preferably, relay module also comprises an ON/OFF variable standby output interface J2, for output for subsequent use in emergency circumstances.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
