Be that 30V is that example provides embodiment with certain carrier rocket electromagnetic valve circuit output voltage below:
When solenoid valve when work on the arrow: a certain way solenoid valve scaling circuit flow process is: the 30V signal is through R1=2000 Ω, R2=390 Ω, C1=47000PF, and the major parameter of TLP521-4 is:
Get optocoupler input forward voltage drop 1.3V during calculating, transfer ratio considers that by 60% the signal path resistance value is got 7 Ω (to about 100 meters of cable length of the present utility model, survey about 7 Ω of impedance on the arrow, device proper has 100 Ω resistance on the arrow).
The optocoupler input parameter calculates
The normal condition optocoupler flows through electric current:
The optocoupler output parameter calculates
When IF=10.6mA, IC=10.6 * 60% ≈ 6.3mA
Result of calculation: the optocoupler output current satisfies the input II6 ∽ 8mA requirement of used 54 family chips of the utility model.Signal is through SNJ5400J oppositely back and second SNJ54121J
Reverse again after the state logic nand operation of end, the result squeezes into the B input end of first SNJ54121, the output of its Q end and isolate input signal be reversed the NOR-logic computing, its result squeezes into the A1 input end of second SNJ121J after oppositely through SNJ5400J.

The pulse width of result of calculation has promptly guaranteed the stable upset of sift register (input pulse width of clock＞40 η S), avoided missing the counting next time (arrow carry device solenoid valve work for the first time close the back) of solenoid valve again, so the technological scheme of present embodiment can accurately, normally be calculated the work number of times of arrow live magnet valve to opening for the second time the minimum 4S of being blanking time.
Working principle flow process of the present utility model:
When solenoid valve is worked on the arrow: carry equipment from arrow and send down 30V, 1,2 pins that are input to SNJ5400J through low level behind R1, R2, C1, V1, the TLP521-4 buffer circuit are low level (being designated hereinafter simply as " 0 "), and 3 pins are output as high level (being designated hereinafter simply as " 1 ") and send 4 pins of SNJ5400J and second SNJ54121J after the NAND Logic computing
It is " 0 " that logical AND inverse result is carried out in the output " 1 " of end, then 6 pins of SNJ5400 outputs " 0 ".
3 pins of SNJ5400J also output to simultaneously behind 3 pins of SNJ5402J Q end with first SNJ54121J to carry out the NOR-logic operation result and is " 0 " for " 1 ", and 1 pin of SNJ5402J is output as " 0 ".
1 pin of SNJ5402J is output as " 0 " 11 pins after 12, the 13 pin input logics of SNJ5400J are reverse and is output as " 1 ", and this rising edge from low to high is for the A1 end input of second SNJ121J, result
Still be " 1 ".Guarantee the 6 pins outputs " 0 " of SNJ5400J when so solenoid valve is worked on arrow.
The 6 pins outputs " 0 " of SNJ5400J are output as " 1 " through reverse 8 pins of 9,10 pins of SNJ5400J, and this rising edge from low to high is for the B input of first SNJ121J, and its Q end is output as rollover states from low to high.
This from low to high rising edge insert behind 8 pins of SNJ54164J its corresponding first and be output as " 1 ".First output 3 pin of SNJ54164J are " 1 ", deliver to first input 1 pin of SG2003J, drive reverse first output pin through SG2003J, and promptly 16 pins are output as " 0 ", with the adhesive of corresponding K1 relay line bag.After the adhesive of relay line bag, corresponding, two pairs of also adhesives of getting an electric shock, wherein the pair of contact adhesive can maintain the coil of relay, makes relay keep normally off; Another can be so that the lumination of light emitting diode of corresponding connection to the contact adhesive.
On the arrow behind the closed electromagnetic valve:
With identical solenoid valve work the time on the arrow, signal is input to SNJ5400J through the buffer circuit high level 1,2 pins are " 1 ", and 6 pins are exported " 1 " after reverse back 3 pins are " 0 ", deliver to 4 pin nand operations, send the input of 9,10 pins.8 pins of SNJ5400J are output as " 0 ", and this is by the B input for first SNJ54121J of the trailing edge of high step-down, and its Q end output is inoperative, so signal is through behind the SNJ54164J, and its corresponding first is output as " 0 ", i.e. displacement output." 0 " output of SNJ54164J drives through SG2003J and oppositely is output as " height ", its corresponding relay can not adhesive, relay can not adhesive then be represented not work of solenoid valve, do not count, in this case, the relay line bag of attracting state disconnects before, but that a pair of electric shock that relay coil is kept on-state, because the characteristic of relay as can be known, this a pair of electric shock can continue to be kept closed, there is circuit diagram to see, one end of relay line bag is connected with the output of driver chip and the Chang Kaiduan of relay simultaneously, so, after Chang Kaiduan and middle interruption are kept closed, though relay line bag disconnects, but the light emitting diode at online bag in parallel two ends is still switched on, (line bag the other end connection+5V, the middle disconnecting of relay) like this, the light emitting diode that connects later still keeps luminance, and this has also just indicated the operating log that once opens the light of solenoid valve on the arrow cleverly
If this solenoid valve closure has again been started working, can repeat the signal flow of working state so, when signal is gone to sift register SNJ54164J, this chip can be exported second output, and then, second of driver output can engage relay K2, and so next K2 goes up the light emitting diode that connects and can continue luminously, this solenoid valve work has been described 2 times.By the time mould flies after the off-test, the light emitting diode that only need have a look this solenoid valve correspondence has several maintenances luminous, just can know clearly very much the working state of this solenoid valve, change former post personnel fully and wanted mould to fly to test overall process to wait for always on the post and to count solenoid valve work number of times at any time, the problem of the state of over sight (OS) meter often occurred leaking.
The utility model is used for a plurality of instruments of certain large-scale carrier rocket Distance Test launch control system at present, realizes that the electromagnetic valve circuit overall process is checked cumulative number in the carrier rocket prelaunch testing.Thereby improve adaptability and the feasibility of this carrier rocket to the high density launch mission.The utility model has passed through the actual verification of the true emission in more than 10 combined test, match test and target range of certain large-scale carrier rocket emission over nearly 3 years, has reached intended purposes, working properly, reliable in quality.
