Description
Technical field
The invention belongs to Safety Technology for Industry field more particularly to a kind of detections of industrial stokehold technological process safety
Method and system.
Background technology
Currently, the prior art commonly used in the trade is such:
Industrial (industry) refers to collection raw material-pretreatment, and they is processed into work and the process of product.Industry is society
The product of division development, by handicraft, mordern industry, the several developing stage of modern industry.Industry is the weight of secondary industry
Component part is wanted, light industry and heavy industry two major classes are divided into.2014, Chinese industrial total output value was more than U.S. up to 4 trillion dollars
State becomes No.1 industrial production state of the world.However, existing industrial stokehold is powered by traditional approach, electric energy is expended, if
Appearance powers off, and cannot continue production work;Existing industry security accident occurs frequently simultaneously, and safety is low.
Computer screen image is not all to change at the moment, only has parts of images changing in the most of the time, if
Only the parts of images to change is transmitted, then will greatly reduce screen data transmission amount.Patent 201210264229.7
The present frame of desktop picture is subjected to piecemeal, and builds hierarchical index, it is slow according to hierarchical index detection present frame relative image block
The modified-image block deposited and do not change image block, after modified-image block is compressed with do not change image block in image block caching
Label is packaged into final transmission data together;Patent 201310318030.2 divides an image into multiple areas of X row Y rows first
Domain makes comparisons to the content in each region with the same area of previous frame image, if this region in have and change,
Then the data in the region are filled out with the header of identified areas information, then carries out compression transmission;Patent 201210544289.4 is logical
It crosses and Format Type identification is carried out to source data to be transmitted before coded treatment, selected for the source data of different-format type
Different compression algorithms.
Common image transmitting algorithm is fixed block image transmitting algorithm, the algorithm in screen picture Transmission system at present
Screen is subjected to piecemeal based on rectangle, and each piecemeal is numbered, the size of each piecemeal and the quantity of piecemeal are fixed
, then the data of front and back adjacent two width bitmap are preserved, and is compared respectively according to corresponding number block, if figure
As changing, the current image in the block of transmission is compressed.Judge method that whether front and back two frame screens change have direct comparison method and
CRC comparison methods.Direct comparison method is compared the internal storage data byte-by-byte of front and back two frames lattice screen;CRC comparison methods calculate
The crc value of image data judges whether image changes by comparing the crc value of two field pictures.Due to fixed block image
Transmission algorithm is only sent every time changes image data in the block, so the transmission quantity of data can be reduced.
The number of fixed block image transmitting algorithm screen block is difficult to determine, if number will excessively cause piecemeal to handle
The summation of time is more than the transmission time of whole screen data, although network bandwidth occupancy in this way is small, real-time may decline;If a
Number is very few, then the network bandwidth fall that more whole screen processing occupies is little, and speed improvement effect unobvious have reduction transmission
Data volume is dependent on image block number and piecemeal number is difficult to the defect set;Fixed block image transmitting algorithm screen point
The number of block and the resolution ratio of screen are closely related, if resolution changing, to guarantee network bandwidth, occupancy is small to be had to adjust
The number of algorithm screen block, bad adaptability;Fixed block image transmitting algorithm is solid to the size and number of screen block
Fixed, when screen picture region of variation is placed exactly in the critical point of multiple rectangular partitions, it just will appear the piecemeal of image change
Excessive phenomenon cannot effectively reduce transmitted data amount.

Pay much attention to.According to research reports, the structure of tunable filter mainly has micro-strip, suspended substrate stripline, dielectric resonator, substrate to integrate wave to root
Lead forms such as (SIW).Adjustable realization method mainly has varactor, PIN diode, RF MEMS technologies etc..According to tuning
Mode can be divided into:1, mechanical tuning;2, electric tuning;3, acousto-optic tunable.It can be divided into according to tuning content:1, centre frequency can
Tunable filter;2, bandwidth tunable filter;3, centre frequency and bandwidth while tunable filter.
Currently, having carried out a series of research work to tunable filter both at home and abroad, and achieve some achievements.But it reports
The filter that road comes out generally is faced with following some defects:
(1) tunable filter is due to generally by controlling the coupling between multistage resonator, being tuned bandwidth so that band
Broad tuning range very little cannot meet the requirement to bandwidth tuning range in practical application.
(2) tunable filter is due to generally using multistage resonator structure, and using coupling input way of output etc., makes
The insertion loss for obtaining filter is larger.
(3) absolute bandwidth of passband changes during centre frequency tunes, and cannot meet frequency in practical application
The requirement that electric timing absolute bandwidth is kept constant.
(4) during being tuned to centre frequency or bandwidth, stable filtering performance cannot be kept, is mainly manifested in
Small when big when return loss and insertion loss, passband ripple is uneven etc. affects the stability of system Whole Response.
In conclusion problem of the existing technology is:
Existing industrial stokehold is powered by traditional approach, expends electric energy, cannot then continue to produce if there is power-off
Work;Existing industry security accident occurs frequently simultaneously, and investigation is difficult, and safety is low.
Screen block number is difficult to determine with bad adaptability, when screen picture variation zone in fixed block image transmitting algorithm
Domain is placed exactly in multiple rectangular partition critical points, cannot effectively reduce transmitted data amount the problem of.
There are Insertion Loss in adjustable process for existing variable band-pass filter greatly, absolute bandwidth changes, filtering characteristic is unstable
