Description

A kind of pointer instrument

Technical field

The utility model belongs to intelligence instrument field, is related to a kind of pointer instrument.

Background technology

With the development of science and technology, digital instrument is simple and clear with its registration, and compact gradually refers in replacement Pin type instrument, but digital instrument chip is easily caused registration to be forbidden by the interference of electromagnetic field, and the use year of digital instrument Limit is often more much lower than pointer instrument, therefore some occasions are still largely using pointer instrument.

The advantages of pointer instrument be it is durable, it is cheap, and fluctuation (i.e. the swing of pointer) energy of its registration The change for representing parameter of image, the advantages of its is important be, for some special occasions, its deicing characteristics can allow It can allow it to work under water in the local work of cold weather, its fire resistance characteristic well, and it is not by magnetic interference characteristic energy It is allowed to be worked etc. under high-intensity magnetic field interference, these characteristics allow its performance to remain to the advantage of normal work in the presence of a harsh environment, make It can not be substituted by other kinds of instrument easily.

However, the work such as the detection of pointer instrument, maintenance, identification and correction traditionally people using artificial interpretation Mode is completed, but because this method of discrimination of the artificial origin of each side inevitably produces some errors, and It is not that data signal needs artificial interpretation, it is impossible to adapt to network management.With the fast development of DSP technologies, using DSP to big The fast throughput of data is measured, the novel intelligent pointer instrument data that a kind of precision is high, real-time is high is designed and is possibly realized.

Utility model content

The shortcomings that the purpose of this utility model is to overcome above-mentioned prior art, there is provided a kind of pointer instrument, this refers to Pin type instrument can realize that the data signal of pointer reads and shown.

To reach above-mentioned purpose, pointer instrument described in the utility model includes pointer instrument body, DSP-BF609 Processor, LCD display, the imaging sensor of computer and the image information for gathering pointer instrument body, image The output end of sensor is connected with the input of DSP-BF609 processors, and output end and the LCD of DSP-BF609 processors show Show that device and computer are connected.

DSP-BF609 processors include pixel synthesizer and streamline vision processor, wherein, the output of imaging sensor End be connected with the input of pixel synthesizer and the input of streamline vision processor, the output end of pixel synthesizer and LCD display is connected, and the output end of streamline vision processor is connected with computer.

It is connected between the output end of imaging sensor and the input of streamline vision processor by DMA33 controllers Connect.

Also include DDR2 buffers；Streamline vision processor includes the 3rd convolution module CNV2, the first convolution module CNV0, the second convolution module CNV1, PMA module, PEC modules and CORE0 modules；Imaging sensor successively through DMA33 controllers, 3rd convolution module CNV2, the first convolution module CNV0, the second convolution module CNV1, PMA module, PEC modules, DDR2 buffers And CORE0 modules are connected with computer.
