And; Said serial ports level transponder comprises shell, power supply, input interface, output interface, status indicator lamp and control circuit; Be provided with power supply and control circuit in the enclosure; The plane is provided with mains switch and status indicator lamp on shell, is symmetrically arranged with input interface and output interface respectively in the upper and lower side of shell.
And said input interface is two groups of DB9 interfaces and seven needle interfaces, and the both sides of each DB9 interface are provided with one or seven needle interfaces; Said output interface is totally eight of two symmetrical groups.
And; Said control circuit comprises level translator and photoisolator; It specifically is connected to: input interface is sent to external signal on the level translator; Level translator converts communication signal into the TTL signal and sends into photoisolator, converts communication signal into through output interface output through level translator again through the TTL signal after isolating.
And said level translator adopts MAX232, and photoisolator adopts MAX203.
Advantage of the present invention and good effect are:
1, native system has scientifically been set up the Ocean Surveying detection system; With computer center, the Big Dipper and the GPS navigation system of monitoring transmit-receive platform and various collecting devices, the Big Dipper and the terminal in each oceanic observation; It is regular all to adopt a serial ports level transceiver to carry out data wire, makes various communication apparatus organically combine, and carries out level conversion simultaneously; Made the conversion of communication mode in order; Improve communication efficiency, increased transmission range, strengthened the overall technology level of Ocean Surveying monitoring effectively.
2, the employed level transceiver of native system utilizes technology such as existing ripe level conversion, interface expansion, not only a serial ports is expanded into a plurality of serial ports, and has realized the conversion of RS-422 serial communication pattern and RS-232 serial communication pattern.
3, the employed level transponder of native system adopts photoisolator to isolate between level translator; Make and directly be not electrically connected between each communication apparatus; The pressure reduction surge phenomenon of effectively having avoided ground wire pressure reduction to cause, protected each communication apparatus safety and between normal communication.
