2, for built-in terminal user, the method that the embedded main board that the present invention proposes uses in distinct device, same embedded main board can be made to adapt to plurality of devices, reduce user and buying and safeguarding the cost and effort that different embedded main board spends.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the embodiment of the present invention;
Fig. 2 is the application schematic diagram of the embodiment of the present invention in distinct device.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
The embedded main board peripheral interface adopted in the embodiment of the present invention comprises more than 3 network card interface, 3 RS232 serial ports, 3 RS422 serial ports, 4 USB interface and 16 GPIO, and peripheral interface can access the mobile devices such as the USB keyboard of USB mouse and standard simultaneously.
The process flow diagram of the embodiment of the present invention as shown in Figure 1, comprises the following steps:
101 embedded main boards power on loading Linux operating system kernel;
102Linux operating system searches flash storage reserved area, check in the whether loaded flash storage of self-triggered program executable file, application program executable file and configuration file, if downloaded, entered step 104, do not download and then enter step 103;
103 create file in flash storage, self-triggered program, application program and the configuration file corresponding from application program being downloaded in flash storage is also stored in different file respectively, then restarts kernel or powered-down switch restarting equipment with instruction reboot;
The path of self-triggered program executable file place file and EXENAME to be added in the configuration file rc.local that operating system carries by 104, and operating system calls self-triggered program;
105 self-triggered programs read embedded main board ID, call the application program be associated according to ID value from flash storage;
106 application programs read the configuration file corresponding with oneself, the correlation parameter such as IP address, gateway of initialization system.
As the preferred embodiment of the present invention, in above-described embodiment workflow when reading embedded main board ID, also to detect each in ID value, when detecting that in the ID of M position, the level value of each is 0 or 1, return reading normal instructions to (SuSE) Linux OS, (SuSE) Linux OS calls according to ID value the application program be associated after receiving and reading normal instructions; Have any place value not to be 0 or 1 when detecting in the ID of M position, then return reading exceptional instructions to (SuSE) Linux OS, (SuSE) Linux OS carries out circulation and reads, until read correct value 0 or 1.
Be illustrated in figure 2 the application schematic diagram of the embodiment of the present invention in distinct device.Equipment 1 and equipment 2 have different peripheral interface quantity, realize different functions, and we put into same embedded main board in equipment 1 and equipment 2, are all loaded into self-triggered program, application program 1 and application program 2 in embedded main board.In the present embodiment, be simplified illustration process, embedded main board ID figure place is set to 3, and namely the value of M is 3, ID value when being 001, invokes application 2 when invokes application 1, ID value is 010.
When equipment 1 powers on, the first loading Linux operating system kernel of embedded main board, (SuSE) Linux OS calls self-triggered program, and self-triggered program lights embedded main board relay indicating light, then, self-triggered program person reads 3 GPIO pins of specifying, reading result is 0,0,1, now self-triggered program invokes application 1, completes the loading of application program 1.
When equipment 2 powers on, the first loading Linux operating system kernel of embedded main board, (SuSE) Linux OS calls self-triggered program, and self-triggered program lights embedded main board relay indicating light, then, self-triggered program reads 3 GPIO pins of specifying, reading result is 0,1,0, now self-triggered program invokes application 2, thus complete the loading of application program 2.
Be not difficult to find out, equipment 1 and equipment 2 have different functions, but put into same embedded main board in equipment 1 and equipment 2, and self-triggered program calls different application programs according to different use scenes, achieve one piece of embedded main board and use in distinct device.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
