Description
Technical field
The utility model relates to a kind of data collector, especially relates to a kind of parallel data high speed acquisition device combining instrument and director front panel for torpedo-launching.
Background technology
Data and signals collecting are the most basic functions of test macro.Data or signal parallel collection, namely sample all input data and signal simultaneously.The data acquisition of existing torpedo-launching combination instrument and director front panel generally adopts and directly gathers and storage mode, the defects such as which exists transmission poor accuracy, speed is low, antijamming capability is weak.In addition, in these instruments there is the shortcoming that sequential not exclusively predicts in the logical circuit of sectional type interconnection structure.
Utility model content
The purpose of this utility model is exactly the parallel data high speed acquisition device providing that a kind of antijamming capability is strong, data accuracy is high, data rate is fast to overcome defect that above-mentioned prior art exists and have the features such as predictability.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of parallel data high speed acquisition device, it is characterized in that, comprise torpedo-launching combination instrument, director front panel, the first filtration module, the second filtration module, CPLD chip and center ruggedized computer, the first described filtration module, CPLD chip, the second filtration module are connected successively, described torpedo-launching combination instrument, director front panel are connected with the first filtration module respectively, and described center ruggedized computer is connected with the second filtration module.
Described torpedo-launching combination instrument and director front panel include switching value output circuit and pilot lamp.
Described center ruggedized computer is connected by parallel-port electrical cable with the second filtration module, and described torpedo-launching combination instrument, director front panel are connected with the first filtration module respectively by parallel-port electrical cable.
Compared with prior art, the utility model has the following advantages:
1, data accuracy is high, antijamming capability is strong, when signal imports into and spread out of parallel data high speed acquisition device, first carries out filtering to data-signal, effectively improves the reliability of data transmission,
2, data rate is fast, and signal data is transmitted by parallel cable;
3, logical circuit has predictability, avoids the shortcoming that sectional type interconnection structure sequential is not exclusively predicted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of parallel data high speed acquisition device, comprise torpedo-launching combination instrument 1, director front panel 2, first filtration module 31, second filtration module 33, CPLD chip 32 and center ruggedized computer 4, the first described filtration module 31, CPLD chip 32, second filtration module 33 are connected to form parallel data high speed acquisition device successively, described torpedo-launching combination instrument 1, director front panel 2 are connected by parallel cable with the first filtration module 31 respectively, and described center ruggedized computer 4 is connected by parallel cable with the second filtration module 33.
Described torpedo-launching combination instrument 1 and director front panel 2 comprise switching value and pilot lamp.
This device mainly through programming to CPLD chip, data acquisition work.CPLD chip is mainly made up of the programmable interconnect matrix unit of FPGA (Field Programmable Gate Array) macroelement around center.CPLD inside adopts the metal wire of regular length to carry out the interconnection of each logical block, so the logical circuit of design has predictability, avoids the shortcoming that sectional type interconnection structure sequential is not exclusively predicted.
