Brief description of the drawings
Fig. 1 is the circuit diagram of floating on water surface register false triggering preventing device of the present invention;
Fig. 2 is the schematic diagram of initiation control box,
Wherein, 1-battery pack, 2-first order relay, 3-water sensor, 4-second level relay, 5-electric cap, 6-initiation control box, 7-safety plug, 8-stopper slot, 9-shell fragment, 10-sensitive switch.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Seawater and river resistivity of water (1 Ω m～100 Ω m) with air resistivity (10
16Ω m) differs greatly, and water sensor utilizes this characteristic to make.In the time that water sensor immerses in seawater or river completely, its resistance is about 0.824 Ω～82.4 Ω.
Refer to Fig. 1, floating on water surface register false triggering preventing device of the present invention comprises battery pack, first order relay, water sensor, second level relay, initiation control box and electric cap.Described first order relay input is connected with battery pack, output is drawn three branch roads, wherein, after one branch road connection water sensor, ground connection is initiation control circuit, two-way is signal output apparatus in addition, connect the sensitive switch of initiation control box, and on signal output apparatus, connect second level relay, and this second level relay connects electric cap.
Refer to Fig. 2, described initiation control box is made up of two sensitive switches and drive system, drive system comprises safety plug, stopper slot, connecting rod and shell fragment, 2 ends of shell fragment one end in contact sensitive switch, the other end connects the connecting rod that is positioned at stopper slot, is positioned at connecting rod one side of stopper slot for promoting the safety plug of connecting rod.When safety plug inserts initiation control box, promote the connecting rod in stopper slot, the connecting rod that is will push shell fragment, and shell fragment presses sensitive switch 2 ends, and 1 end of sensitive switch is connected with 3 ends, is communicated with earthed circuit.And 3 end ground connection of described sensitive switch.
In addition, described first order relay CTL+ end and two outputs are all connected with resistance.
When described water sensor no signal, no current between first order relay CTL+ end and CTL-end, INA end and OUTA1 termination are logical, and INB end and OUTB1 termination are logical, the output of first order relay no current; After described water sensor is immersed in the water, between first order relay CTL+ end and CTL-end, flow through certain electric current, make INA end and the OUTA2 termination of relay logical, INB end and OUTB2 termination are logical.Wherein, described first order relay is dpdt double-pole double-throw (DPDT) electromagnetic relay, and CTRL+ end and CTL-end are the control ends of relay, and OUTA1 end and OUTB1 end are respectively the normally-closed contacts of relay, and OUTA2 end and OUTB2 end are respectively the normally opened contacts of relay.INA and INB are exactly so-called " cutter ", for describing the folding of not coordination of sensitive switch.
Floating on water surface register false-touch prevention forwarding method of the present invention is based on above-mentioned false triggering preventing device, its course of work principle and process are as follows: in the time of water sensor no signal, no current between first order relay CTL+ end and CTL-end, INA end and OUTA1 termination are logical, INB end and OUTB1 termination are logical, the output of first order relay no current.After water sensor is immersed in the water, between first order relay CTL+ end and CTL-end, flow through certain electric current, make INA end and the OUTA2 termination of relay logical, INB end and OUTB2 termination are logical, if initiation control box does not insert safety plug, electric current flow to second level relay, and then detonating primer; If initiation control box inserts safety plug, first order relay output current ground connection, second level relay is not closed, can not produce detonator fused signal.
Therefore floating on water surface register false-touch prevention forwarding method of the present invention, by safety plug being inserted to initiation control box, touches sensitive switch, by the two-way output signal ground connection of first order relay.At this moment, even if register is immersed in the water, make first order relay contact closure, electric current flows out from battery anode, flow through resistance, then flow into battery pack negative pole by two sensitive switches in initiation control box, and do not flow into second level relay coil, second level relay is not closed, can not produce detonator fused signal.
Like this, when aircraft is during on ground, safety plug is inserted to initiation control box, even if at this moment register is immersed in the water also and can not launches, thereby play the effect of insurance.
In the time of real work, fly to join voltage between system ground check socket G and H with avometer measurement pulling up before safety plug, be less than in 0.3V situation and can pull up safety plug; Otherwise pull down floating on water surface register, carry out detailed inspection by producer.When amount voltage, avoid G and H contact short circuit.
In addition, the osculum of floating on water surface register designs of the present invention, only has float recorder rapid, high volume on the water to pour in after the water of certain capacity, just can impel this water sensor, makes it send time break.
By a large amount of verification experimental verifications fully, the present invention has ensured the safe handling of floating on water surface register effectively, has promoted promoting the use of of floating on water surface register, has larger actual application value.
