Abstract
The present invention provides a kind of methods for realizing equipment control based on embedded device CGI, addition chained list is received including BOA to be stored, multithreading reads chained list and carries out CGI business operations, pipeline mechanism is added in select time-out, and CGI is compatible with a variety of browsers using http collocation xml, multi-client submits operation.The present invention solves multi-thread concurrent processing, and reduce delay process, browser may be implemented under different operating system without plug-in unit operational control unit and check facility information by modifying to BOA servers；Present invention delay smaller, more preferably, user more can understand and receive compatibility, and to reduce the operating procedure of user, and then the user experience is improved.
Description
Technical field
The invention belongs to safety precaution, technical field of video monitoring, real based on embedded device CGI more particularly, to one kind
The method of existing equipment control.
Background technology
Http protocol (HyperText Transfer Protocol, hypertext transfer protocol) is for from www server
Transport protocol of the transmission hypertext to local browser.It can make browser more efficient, and network transmission is made to reduce.It is not only
Ensure that computer correctly rapidly transmits hypertext document, which part in transferring documents, and any partial content also determined
Show (such as text is prior to figure) first.
CGI (Common Gateway Interface) is one of most important technology in WWW technologies, is had irreplaceable
Critical role.CGI is interface standard of the external application (cgi script) between WEB server, be in cgi script and
The process of information is transmitted between Web server.
HTTP user name passwords use degist encrypted authentication command interactions, browser to pass through CGI protocol interaction orders
The various device datas that can obtain server-side, obtain various audio and video parameters of security device etc. and control device is various
The operation data of behavioral function encapsulates, and http protocol combination XML format string carries out data transfer
BOA servers are a small and exquisite efficient web servers, are one and run under unix or linux, are supported
CGI, be suitable for the http-server of the single task of embedded coordination, open source, performance are high.
Traditional BOA servers do not support Multi-task Concurrency to handle, and influence more browser login process efficiency.
Invention content
In view of this, the present invention is directed to propose a kind of method for realizing equipment control based on embedded device CGI, to realize
Browser without plug-in unit operational control unit and checks facility information under different operating system.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A method of equipment control is realized based on embedded device CGI, including
BOA receives addition chained list and is stored, and multithreading reads chained list and carries out CGI business operations, and select time-out is added
Pipeline mechanism, CGI is compatible with a variety of browsers using http collocation xml, multi-client submits operation.
Further, the control method specifically comprises the following steps：
(1) user connects equipment CGI services by web browser, files a request；
(2) CGI servers receive parsing CGI protocol translation monitoring devices instruction after request, operate equipment, carry out equipment
Correlation function processing；
(3) after the complete functions of the equipments operation of CGI server process, handling result response web browser, user's operation is prompted
As a result.
Further, the control method further includes：
Web server receives parsing related urls and parameter after user's CGI requests；
Signal is handled changing solicited message addition information processing queue linked list and sending instruction；
Instruction processing thread reads queue after receiving signal, according to URL and CGI required parameters, is converted to monitoring device
Instruction is sent to instruction processing service.
Service processing result response user's handling result is handled according to instruction.
Compared with the existing technology, a kind of method tool for realizing equipment control based on embedded device CGI of the present invention
There is following advantage：
(1) present invention is by modifying to BOA servers, solution multi-thread concurrent processing, and reduces delay process,
Browser may be implemented under different operating system without plug-in unit operational control unit and check facility information；
(2) present invention delay smaller, more preferably, user more can understand and receive compatibility, to reduce the operation of user
Step, and then the user experience is improved.
Description of the drawings
The attached drawing for constituting the part of the present invention is used to provide further understanding of the present invention, schematic reality of the invention
Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings：
Fig. 1 is that a kind of method structure based on embedded device CGI realization equipment controls described in the embodiment of the present invention is shown
It is intended to；
Fig. 2 is that a kind of method flow based on embedded device CGI realization equipment controls described in the embodiment of the present invention shows
It is intended to.
Specific implementation mode
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figs. 1-2, a method of equipment control is realized based on embedded device CGI, including
BOA receives addition chained list and is stored, and multithreading reads chained list and carries out CGI business operations, and select time-out is added
Pipeline mechanism, CGI is compatible with a variety of browsers using http collocation xml, multi-client submits operation.
The control method specifically comprises the following steps：
(1) user connects equipment CGI services by web browser, files a request；
(2) CGI servers receive parsing CGI protocol translation monitoring devices instruction after request, operate equipment, carry out equipment
Correlation function processing；
(3) after the complete functions of the equipments operation of CGI server process, handling result response web browser, user's operation is prompted
As a result.
The control method further includes：
Web server receives parsing related urls and parameter after user's CGI requests；
Signal is handled changing solicited message addition information processing queue linked list and sending instruction；
Instruction processing thread reads queue after receiving signal, according to URL and CGI required parameters, is converted to monitoring device
Instruction is sent to instruction processing service.
Service processing result response user's handling result is handled according to instruction.
The BOA servers of the present invention are a small and exquisite efficient single task http-servers, are not supported at Multi-task Concurrency
Reason, influences more browser login process efficiency, modifies to BOA servers, and chained list multithreading modification processing is carried out to it, is made
It supports more browser client concurrency protocol processing, greatly improves the treatment effeciency of CGI agreements.
The present invention formulates the CGI agreements of simple general-purpose, and xml structures allow the clients such as browser easily to handle, and
The installation of plug-in unit is omitted, coordinates RTMP video previews, realizes the compatibility of all browsers.
Http protocol degist user names password encryption mechanism of the present invention ensures the safety of user name password.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
