Description
Technical field
The present invention relates to Inverse problem field, more specifically, relate to a kind of matrix control system based on Python.
Background technology
In video signal application, matrix is as a kind of signal switching apparatus, requisite often.Due to matrix, producer is numerous, its control protocol and control mode ever-changing, therefore, the control software design designing a flexible compatible numerous model matrix of energy is vital.At present conventional method is that the matrix majorization agreement for each model writes a plug-in unit (dll file or lib file), is loaded by control software design, and generates the corresponding table of a matrix model and target plug-in.Meanwhile, control software design provide several conventional control mode as selective in TCP, UDP, serial ports etc.When needs issue control switching command to matrix, select corresponding control mode and matrix model, control software design finds corresponding target plug-in according to model, the passage bridge interface of invocation target plug-in unit generates corresponding control command code, then by corresponding control mode, control command code is issued, and then realize the switching controls to matrix.
Although existing method implements fairly simple, it has following shortcoming.The first, plug-in unit realizes often needing to use professional language to realize, and as C/C++, C#, VB etc., needs professional and realizes, for amateur developer, have certain technical difficulty; The second, when often increasing a kind of matrix model and control mode, all must compile whole control software design, more time-consuming; 3rd, the method extensibility is poor, and field engineering personnel are difficult to debug.
Summary of the invention
The invention provides a kind of matrix control system based on Python, the Inverse problem order that control software design can issue by the protocol conversion module in this system is converted to the discernible matrix majorization protocol command of matrix, because this system adopts Python to programme, therefore when increasing new matrix model and control mode, without the need to recompilating whole control software design.
For realizing above object, the technical scheme of collection of the present invention is:
Based on a matrix control system of Python, convert matrix majorization protocol command to for the Inverse problem order issued by control software design, comprise order receiver module, protocol conversion module and order sending module;
Wherein order receiver module receives the Inverse problem order that control software design issues, then Inverse problem order is sent to protocol conversion module, Inverse problem order is converted to the discernible matrix majorization protocol command of matrix by protocol conversion module, again the matrix majorization protocol command of conversion is sent to order receiver module, matrix majorization protocol command is sent to order sending module by order receiver module; Order sending module according to the control mode of matrix and matrix create be connected after matrix majorization protocol command is sent to matrix.
Compared with prior art, the beneficial effect of technical solution of the present invention is: the matrix control system based on Python provided by the invention, the Inverse problem order that control software design can issue by the protocol conversion module of its inside is converted to the discernible matrix majorization protocol command of matrix, because this system adopts Python to programme, therefore when increasing new matrix model and control mode, without the need to recompilating whole control software design, Python is easy to learn and use simultaneously, easily modified debugging, therefore can also operate without the need to professional, therefore more easily popularize.
Accompanying drawing explanation
Fig. 1 is the structural representation of matrix control system.
Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent;
Below in conjunction with drawings and Examples, the present invention is further elaborated.
Embodiment 1
The invention provides a kind of matrix control system based on Python, convert matrix majorization protocol command to for the Inverse problem order issued by control software design, as shown in Figure 1, comprise order receiver module, protocol conversion module and order sending module;
Wherein order receiver module receives the Inverse problem order that control software design issues, then Inverse problem order is sent to protocol conversion module, Inverse problem order is converted to the discernible matrix majorization protocol command of matrix by protocol conversion module, again the matrix majorization protocol command of conversion is sent to order receiver module, matrix majorization protocol command is sent to order sending module by order receiver module; Order sending module according to the control mode of matrix and matrix create be connected after matrix majorization protocol command is sent to matrix.
In such scheme, protocol conversion module preserves matrix majorization script, and matrix majorization script adopts Python to write, and the matrix majorization script write is kept in protocol conversion module in the mode of character string.
The system of this method, when starting, first carries out Python context initialization, then creates a dictionary variable, for depositing relevant information.Matrix majorization protocol command, after receiving Inverse problem order, by this order press-in dictionary, then according to the order of this Inverse problem command calls corresponding matrix majorization script generator matrix control protocol, then is sent to order receiver module by protocol conversion module.
The detailed process that wherein control software design issues Inverse problem order to order receiver module is: control software design obtains IP address and the port of order receiver module, set up TCP network with order receiver module to be again connected, control software design, when needs carry out Inverse problem, is connected by this network and Inverse problem order is handed down to order receiver module.
In such scheme, order receiver module is designed to a TCP network service thread, the process of its receiving matrix switching command is specially: order receiver module obtains the listening port of control software design, create again and monitor socket, monitor socket to connect for the network monitoring control software design, after the network listening to control software design request connects, read this network and connect the Inverse problem order sent.
Similarly, order sending module is designed to a TCP network service thread, order sending module to create with matrix according to the control mode of matrix and is connected, the process again matrix majorization protocol command being sent to matrix is specially: order sending module creates communication handle or web socket according to the control mode of matrix, then the matrix majorization order of reception is sent to matrix by communication handle or web socket.
In the present embodiment, matrix majorization protocol command is sent to order sending module by the mode of Thread Messages by order receiver module, order sending module is after receiving Thread Messages, parse matrix majorization protocol command by message parameter, then this order is sent to matrix by communication handle or socket.
Matrix control system based on Python provided by the invention, the Inverse problem order that control software design can issue by the protocol conversion module of its inside is converted to the discernible matrix majorization protocol command of matrix, because this system adopts Python to programme, therefore when increasing new matrix model and control mode, without the need to recompilating whole control software design, Python is easy to learn and use simultaneously, easily modified debugging, therefore can also operate without the need to professional, therefore more easily popularize.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection range that all should be included in the claims in the present invention.
