The second target control signal is obtained after row reverse phase, and is exported by second output terminal P4 to laser 300.It can ensure that center control
The TTL_OUTPUT signal of 200 output of card is transmitted to the first output end P2, is exported by the first output end P2 to laser 300.
Again, as shown in figure 8, for the output of another center control card 200 first control signal (TTL_ in Fig. 8
) and second control signal (LASER_GATE in Fig. 8) OUTPUT.Signal needed for laser 300 in comparison diagram 8 and Fig. 4 it is found that
First object needed for laser 300 controls the first control signal of signal and the output of center control card 200 on the contrary, laser
The second control signal that second target control signal needed for 300 and center control card 200 export is on the contrary, to need to be to center
The first control signal that control card 200 exports carries out reverse phase, needs to carry out reverse phase to second control signal, then only needs the respectively
One control signal passes through signal inversion by output after signal inverter U1 reverse phase to the first output end P2, by second control signal
Vinegar goes out to second output terminal P4 after device U1 reverse phase.At this point, center control card 200 is then exported LASER_GATE signal (second
Control signal) port and Fig. 3 in laser switching device the second input terminal P3 inPin (i.e. fourth signal port)
Connection, center control card 200 export in port and the first input end P1 of TTL_OUTPUT signal (first control signal)
Pin (i.e. second signal port) connection.It is shorted the first bipod bouncing pilotage P8 and the second bipod bouncing pilotage P9 by jump cap,Draw
Foot is connect by signal inverter U1 with second output terminal P4, is madePin passes through signal inverter U1 and the first output end P2
Connection, thus, pass through U1 pairs of signal inverterThe first control signal of pin transmission obtains first object control after carrying out reverse phase
Signal processed, and exported by the first output end P2 to laser 300.It can ensure that the LASER_GATE that center control card 200 exports
Signal obtains the second target control signal after carrying out reverse phase, and is exported by second output terminal P4 to laser 300.
