Abstract
The invention relates to a data storage device for a torpedo director and application. The device is connected with a center computer and a double-port RAM through a transmission bus, the data storage device comprises an MCU and a storage module, and the MCU is connected with the storage module and the transmission bus. Compared with the prior art, the data storage device has the advantages of being long in service life, high in equipment utilization rate, high in reliability, good in real-time performance, convenient to operate and the like.
Description
Technical field
The present invention relates to a kind of data storage device, especially relate to a kind of data storage device for torpedo directoor and application.
Background technology
The storage mode of existing torpedo directoor is all generally that hard disk or CD directly store, and such storage mode exists following defect:
1, data security is poor, the problem such as easily cause that data leak;
2, data storage efficiency is not high, once hard-disc storage needs again to change hard disk after having expired, cause decreasing efficiency, and add labour cost, according to CD, then the speed stored reduces greatly;
3, poor real, is needed could be realized by USB flash disk or CD-ROM drive etc. as read data, causes complex operation step, poor real.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and the data storage device for torpedo directoor and application that a kind of long service life, plant factor are high, reliability is high, real-time is good, easy to operate is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of data storage device for torpedo directoor, this device is connected with central computer and dual port RAM respectively by transfer bus, it is characterized in that, described data storage device comprises MCU and memory module, and described MCU is connected with memory module and transfer bus respectively.
Described transfer bus is Multibus bus.
Described MCU is Intel80188 chip.
Described memory module is Flash flash chip, is provided with multiple storage unit.
The data at every turn stored are written to and are written in the storage unit of least number of times by described MCU.
Also comprise the wireless sending module be connected with MCU, this wireless sending module is connected with remote terminal, accesses and read data for remote terminal.
For an application for the data storage device of torpedo directoor, it is characterized in that, comprise the following steps:
1) central computer calculates object parameter data;
2) central computer is every setting-up time, is sent in dual port RAM by the data calculated;
3), after central computer sends, data recording command is sent to MCU;
4), after MCU obtains instruction, from dual port RAM, the data of record are obtained by transfer bus;
5) data of acquisition are put into the storage unit that memory module is written into least number of times by MCU.
Compared with prior art, the present invention has the following advantages:
1, long service life, plant factor is high, reliability is high, allow each data of record that need be written to the storage unit being written into least number of times by MCU, allow the life-span of each storage unit be fully utilized, ensure that the reliability of data.
2, real-time is good, by central computer is existing, data is put into dual port RAM, then sends instruction and automatically read data to MCU, MCU, thus effectively improve data reading performance using redundancy.
3, easy to operate, remote terminal gets final product visit data by wireless network, and reads data, improves operability.
