Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

step 101, a server receives position coding data sent by a first terminal, wherein the position coding data comprises a position parameter and an identification parameter.
The first terminal is provided with a digital pen with a camera module, a processing module, a storage module and a communication module. The position encoding pattern in this embodiment is specifically a dot matrix encoding pattern. When the pen point of the digital pen moves on the output medium, the camera module collects dot matrix coded images, the dot matrix passing through can be photographed at the speed of 100 sheets per second, the processing module processes the position coded images collected by the camera module to obtain digital signals, the digital signals are stored in the storage module, and the communication module sends the digital signals to the server in real time or non-real time.
The lattice coding pattern is formed by arranging a plurality of lattices according to a special algorithm rule, and the lattices represent special coordinate position information through a special coding mode. The dot matrix is used for providing the digital pen with coordinate parameter information, and ensures that the digital pen can accurately record the written handwriting when writing on an output medium.
Before the server receives the position code data sent by the digital pen, the digital pen needs to be registered in the server. After registration, data transmission can be carried out between the digital pen and the server, the digital pen sends a registration request message to the server, and the registration request contains identification information such as a serial number of the digital pen; the server returns a response message to the digital pen after storing the identification information of the digital pen. The server and the digital pen can perform bidirectional data transmission.
And 102, acquiring control parameters according to the position parameters and the identification parameters.
The control parameter may be any parameter selected from the position parameter and the identification parameter.
Wherein, the position parameters specifically include: the first terminal collects at least one of page address information of the position encoding data and area address information on the page.
The position coding data is a part divided from the position coding database, the position codes in the position coding database are divided into different parts such as books, chapters, pages, areas and the like, the digital pen acquires the position coding data and obtains position parameters at the same time, and the page address where the position codes are located and the specific area position in the page can be determined according to the position parameters.
The identifying parameters specifically include: at least one of ID information of the first terminal, user identification information of the first terminal, geographical location identification information, and email address information.
The ID information of the first terminal includes a serial number of the digital pen, and the like, the user identification information of the first terminal specifically includes a user name and the like associated with the first terminal, and the geographic location identification information includes geographic location information where the first terminal is located, and the email address information includes an email address and the like associated with the first terminal. The characteristics of the first terminal and the characteristics of the user can be identified from the above identification parameters.
And 103, inquiring a control object corresponding to the control parameter.
Before inquiring the control object corresponding to the control parameter, the method also comprises the step of generating the control object: selecting at least two control parameters from the position parameters and the identification parameters, and recording the control parameter values; and logically combining at least two control parameter values to generate a control object.
In particular, a plurality of control parameters AND control parameter values are combined into several statements, forming a control object, using logical operators (e.g., AND, OR, NAND, NOR, andsntot). Therefore, the control parameters and the control objects have an association relationship, a plurality of control parameters may correspond to one control object, and the corresponding control object can be obtained through the control parameters.
And 104, acquiring control information according to the control object.
Specifically, the control information corresponding to the position coded data is inquired according to the control object. The control object maps the position-encoded data to corresponding control information.

And 105, identifying the position coded data to obtain identification result data.
Specifically, the data on the output medium having the position code includes input type data, functional type data, and the like. The functional data may be implemented by embedding different functional information in the position code. When the digital pen collects position coding data on an output medium, if the collected position coding data is input data and is sent to a server, the server decodes the position coding information to generate a digital sequence; acquiring first position information according to the digital sequence; and generating position track information according to the first position information. The digital sequence is a dot matrix coding coordinate sequence, the first position information is the position information of dot matrix coding calculated according to the coordinate sequence, and the position information can be connected into tracks according to the time sequence, so that the electronization of handwriting writing is realized.
If the functional data are collected and then sent to the server, the server decodes the position coding information to obtain second position information; and inquiring the function information corresponding to the second position information. The second position information is position information of the functional data, the position information is associated with corresponding functional information, and the server can inquire the corresponding functional information according to the position information, so that corresponding functional operation is realized. The function information may implement different application services, such as sending an email, sending a fax, clicking to obtain application data, and the like.
The purpose of identifying and then sending the position code is to directly perform corresponding operations, such as displaying, storing, performing corresponding function operations and the like, after the data receiving party receives the data, without decoding and identifying steps, thereby reducing the complexity of application service development.
And 106, sending the identification result data according to the control information.
Specifically, the identification result data is sent to a data receiving party in the form of a network address according to the related address and the data format requirement in the control information, for example, a Uniform Resource Locator (URL), an IP address, an email address, a fax number, and the like.
According to the data flow direction control method provided by the embodiment of the invention, the control parameters are obtained according to the position parameters and the identification parameters in the position coding data, and the control objects corresponding to the control parameters are inquired; acquiring control information according to a control object; carrying out identification processing on the position coded data to obtain identification result data; and sending the identification result data according to the control information.
