The defects such as capacity of resisting disturbance is weak.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of Information Security is provided
The navigation data harvester high, capacity of resisting disturbance is strong, real-time good, data accuracy is high and application.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of navigation data harvester, it is characterised in that include radar, sonar, the first analog to digital conversion circuit,
Second analog to digital conversion circuit, the first latch, the second latch, decoder oralia, transfer bus and torpedo
Director central computer, described radar, the first analog to digital conversion circuit, the first latch be sequentially connected with,
Described sonar, the second analog to digital conversion circuit, the second latch are sequentially connected with, described the first latch, second
Latch is connected with decoder respectively, in described decoder oralia, transfer bus and torpedo directoor
Heart computer is sequentially connected with.
Described the first analog to digital conversion circuit, the second analog to digital conversion circuit all use SDC1704 analog-to-digital conversion circuit.
Described and oralia is 608B oralia.
Described transfer bus is Multibus bus.
The application of a kind of navigation data harvester, it is characterised in that comprise the following steps:
1) data of employing are transferred to the first analog to digital conversion circuit, the second analog digital conversion electricity by radar and sonar respectively
Road；
2) the first analog to digital conversion circuit, the second analog to digital conversion circuit are converted to number to the analogue signal of its respective reception
Word signal, and the digital signal after conversion is transferred to the first latch, the second latch respectively；
3), after the signal each received is latched by the first latch, the second latch, decoder all it is sent to；
4) decoder is sent to after being decoded by the digital signal received and oralia；
5) and oralia is transferred to torpedo directoor central computer by transfer bus.
Compared with prior art, the invention have the advantages that
1, Information Security is high, capacity of resisting disturbance is strong, by the analogue signal of reception is converted into digital signal,
It is effectively improved data transmission security and capacity of resisting disturbance；
2, real-time is good, and the data that radar, sonar gather are by transmission plate real-time Transmission；
3, data accuracy is high, it is achieved low cost, the data acquisition for front end uses two complete equipments, for rear
The total a set of equipment of end, thus reduce cost on the basis of ensureing data accuracy.
