Embodiment
Main thought of the present invention is: be separated with industrial application software by platform software; Platform software is compiled into platform executable image, and downloads in communication module group hardware in advance; Platform software determines whether load industry applications executable image according to external command, if will load, then jumps to industry applications reflection entry address and performs; Secondary developing platform provides secondary development software package, comprises second development interface in software package, completes industry applications calling second development interface; Platform software is responsible for the functional realiey of second development interface.
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention is described in detail.
As shown in Figure 1, the sector application of traditional secondary development platform and platform software architecture schematic diagram, the sector application of traditional secondary development platform is together with close-coupled with platform software, industry applications cannot standalone upgrade, compiling link together with platform software is needed during structure, length consuming time, efficiency is low.Sector application is separated with platform software by secondary developing platform of the present invention, generates two independently executable images, and is connected with platform software by industrial application software by second development interface.
Please refer to shown in Fig. 2, it is embodiment of the present invention terminal secondary development device composition schematic diagram, it comprises secondary developing platform, and described secondary developing platform comprises: secondary developing platform software, secondary development software package, communication module group hardware and secondary development specification documents.
Platform software and industrial application software independently compiling link generate two independently executable image files.Platform executable image file is burnt in communication module group in advance.Complete the basic hardware initialization of M2M terminal, protocol stack initialization etc., for sector application provides the second development interface of the main professional atility such as other communications protocol comprising note, voice, data transmission and customization, and be responsible for receiving load instructions, carry out the loading of sector application executable image.
Platform software is compiled translator by platform provider or other and is compiled into platform executable image, and downloads in advance in communication module group hardware.
Platform software need not be open to sector application.The platform executable image file generated after platform software compiling is burnt in communication module group in advance, when there is no sector application firmware, firmware in communication module group still can normal independent operating, has common communication function, supports AT order and basic telecommunications business.
Secondary development software package is for developing industrial application software, and industrial application software and second development interface storehouse are built by compiling link script, generates independently sector application executable image file.Secondary development software package comprises second development interface storehouse, function header file, compiling link script module, and user uses this kit to develop specific industry applications.Sector application developer uses secondary development Development of Software Package, and passed through by compiled sector application executable image file after in replication tool programming to communication module group, this communication module group just becomes the M2M terminal with specific industry application function.Sector application image file can download in the file system of terminal by network or preserve in nonvolatile memory by the edition upgrading of SS later, reloads.
Especially, platform software is when carrying out compiling link, and need to load description document by amendment dispersion, the load operating for industrial application software reserves the special region of memory of next block.
In the present embodiment, terminal program running memory space address is 0x2,000 0000 ~ 0x23FF FF00, and wherein platform software is reserved 0x2,150 0000 ~ 0x2,170 0000 this section of memory headroom and used to industry applications.Sector application map program is when compiling link, and being loaded into address is 0x2,150 0000, and entry address is 0x2,150 0000.
Because sector application executable image is separated with platform executable image, need to set up corresponding relation between the second development interface of two executable images, complete actual interface interchange.Secondary developing platform of the present invention, has the realization of second development interface with the software of secondary development bag in platform software.
Wherein, platform software realizes second development interface concrete function.
Especially, platform software needs the address of the function pointer of second development interface in internal memory to fix.
Preferably, the present embodiment defines an array api_array in platform software, second development interface function pointer is left in this array according to certain order, by amendment scatter-loading file, the load address of this array is fixed on memory address 0x20750000.
In secondary development bag, the realization of second development interface is function pointer redirect, jumps to the array of pointers api_array that memory address 0x20750000 place stores, and calls this second development interface by access second development interface function pointer wherein.
Communication module group hardware is used for transmission and the communication of information.
The realization of second development interface is had with the software of secondary development bag, for realizing videoing the interface interchange after being separated in platform software.
Please refer to shown in Fig. 3, be the structure schematic flow sheet of platform in embodiment of the present invention terminal Secondary, it comprises:
