Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
In the conventional architecture of server/pc+terminal equipment, a specific server/PC needs to be configured and a specific library file needs to be installed for normal use, as shown in fig. 1. In the present application, only a common PC with a browser is needed, as shown in fig. 2.
As shown in fig. 3, in this embodiment, a method for remote control and loading and upgrading of a signal transceiver and channel simulation terminal is provided, which includes the following steps:
(S1) writing HTML webpage programs such as codes, information setting, query display and the like according to the service of the terminal equipment.
(S2) since the terminal equipment and the external interaction part are C language codes based on the DSP chip, a read-write file applet based on the C language is required to be written firstly, then an HTML file is read in the form of hexadecimal stream, the obtained hexadecimal data stream is stored in a one-dimensional array, and then information of the array such as name, address, length and the like is stored by a structural body, wherein each field in the array and the structural body is defined as follows:
const char http_updata_html[]＝{}
typedef struct{
char*file_name；
char*file_array；
int file_length；
}PAGE_ITEM；
and finally, storing all the information into a header file of h.
And S3, opening an HTML thread in the DSP program in the terminal equipment, wherein the thread is used as a server side of an HTML webpage and is mainly responsible for HTTP (Hypertext Transfer Protocol) protocol related processing work, such as protocol encapsulation and analysis, service scheduling and the like.
And (S4) placing the h header file generated in the step S2 into a DSP code in the equipment and the c file of the HTML thread in the step S3 contains the header file, so that the DSP program compiles an array, related information and the like in the header file into a memory of the code during compiling, and the DSP program in the terminal equipment embeds the HTML webpage source code.
(S5) opening up a network thread in the DSP program inside the equipment, wherein the thread is used as a service end. It is necessary to determine the IP address of the device and save the IP address of the counterpart when connected for use as a bridge for interaction with the outside, such as data reception and transmission.
(S6) when the PC uses the web browser to connect the equipment through the equipment IP address, the HTML web browser automatically searches the corresponding IP address equipment in the local area network and then connects to the network thread of the DSP inside the equipment. After the network thread in the equipment is connected, firstly, the communication address of the browser is saved, then the HTML thread is called, the array in the h-head file compiled into the memory in the step S4 is returned to the browser of the PC through the thread, and the browser of the PC automatically analyzes the data after receiving the data from the equipment and converts the data into HTML webpage content for a user to use.
And (S7) after the browser of the PC receives the information returned by the equipment and generates a corresponding HTML webpage, a user can perform corresponding business operations on the browser according to the business requirements of the terminal equipment, such as injection of instructions, query operation of the information and the like on the equipment. The browser generates a corresponding HTTP protocol frame according to the corresponding control response and then sends the HTTP protocol frame to the equipment, the internal DSP program of the equipment analyzes the HTTP protocol after receiving the frame data sent by the PC, and then invokes a corresponding processing function according to the content of the protocol analysis to process the service.
And S8, when the user sends a service of a setting type, such as parameter setting, after receiving a frame protocol sent by a PC browser, a DSP program in the equipment analyzes the HTTP protocol in an HTML thread, then invokes a corresponding service processing function to acquire setting parameters from the PC browser, sorts and stores the parameters, and finally sets the parameters of the equipment according to service scheduling requirements to finish user setting work.
(S9) when the user transmits a query type service, such as a query of status information. The browser of the PC generates a corresponding HTTP protocol according to the operation of a user, then sends the HTTP protocol to a DSP program in the equipment, an HTML thread in the DSP program analyzes the data after receiving the data, then calls a corresponding query service function, and when the DSP query service function of the equipment is called, the queried data is firstly arranged and packaged. And then the HTML thread indexes and searches the content in the webpage array in the step S4 according to the tag, the keyword and the like, replaces the corresponding indexed content with the data after query encapsulation, and reconstructs a new array, finally returns and sends the new array to the PC browser through the HTML thread, and the browser re-analyzes the data sent by the equipment after receiving the data, so that new HTML webpage data is generated, and the query and update operation of the webpage data is realized.
(S10) when the equipment needs version upgrade, the flow is shown in FIG. 4, and the PC machine submits the upgrade file through the browser selection equipment upgrade service window. The browser automatically reads the updated file data, encapsulates the read data with HTTP protocol frames, and then sends the data to the device.
(S11) after the DSP network thread inside the device receives the data from the browser, the data is transferred to the HTML thread. The HTML thread carries out frame decomposition processing on the data packet according to the HTTP protocol to obtain the file data to be updated, and then the DSP replaces the data in the old version in an overwriting mode and saves the data as an executable file format of the equipment, thereby achieving the aim of updating the equipment.
And (S12) after the terminal equipment finishes upgrading and updating, the whole equipment is reloaded and operated in a soft restarting mode, so that the upgrading work of the whole equipment is realized.
In summary, the terminal devices with different functions such as radio frequency channels, channel simulation, signal processing, communication, network interaction and the like in various systems in the fields of communication, radar, electronic countermeasure, navigation and the like can change the traditional server/PC software into the HTML webpage to be embedded into the DSP program of the terminal device after the processes, so that the mode that one device in the traditional mode corresponds to one server/PC is abandoned, the matched library file and the like for running the software are not needed, the mode that the device and the server/PC upper computer software are bound is broken, the flexibility of the device is improved, and the device resources, the space resources and the like are saved. After the application is used, all the previous functions can be realized by only one common PC with a browser, and meanwhile, the remote control and loading work of a large number of devices can be supported.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
