Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
The implementation procedure of the Secondary of the integrated embedded language of Excitation Controller for Synchronous Generator control program of the present invention is as follows:
1) the embedded shell script of lua language compilation is adopted, and the language running environment of shell script is entered in host program with the mode chain of application library, host program is the field regulator C language control program developed in vxworks real time operating system, type according to operating system and compiler revises script environment program, and compiling is by return state pointer.
2) interface function of accessing host program from shell script is write according to function prototype, input parameter, output three parts: the interface function of accessing C programmer from lua all needs the interface shape with identical prototype typedefint (* lua_CFunction) (lua_State*L) to write; In the new function structure of writing, obtain the next parameter of shell script transmission by the lua_toXXX function in CAPI; When needing to return results, by lua_pushXXX function, result is pressed in stack, then returns results number.
3) write the interface function by host program invoke script program, write according to following steps: first, interface function by the lua_getglobal function in CAPI by script function name pop down; Then, use lua_pushXXX function that the parameter of needs is pressed into virtual stack in order, re-use lua_pcall function and perform shell script; Finally, lua_toXXX function is used to obtain the operation result of script application programe.
4) error handle function is write: when lua runs throw exception, obtain script error code by lua_tostring function from stack space, and the information such as the time obtained from operating system and position are saved in journal file, and deliver to terminal demonstration.
5) running environment of initializtion script program and running status:
51) use the luaL_newstate function creation lua running environment in CAPI, use luaL_openlibs to open all java standard libraries, initializtion script language running environment and running status.
52) use the lua_register function in CAPI that the interface function needed from shell script access host program is registered to lua running environment, call for shell script.
53) use the luaL_loadfile function in CAPI to load shell script, luaL_loadfile function, from a files loading lua application source code, compiles, then compiling result is returned with pointer form.
The access process of shell script of the present invention is as follows:
1) Run Script program, uses host program invoke script program interface functions to perform shell script in host program;
2) after shell script is finished, in host program, call lua_close function, close shell script and running environment.
As shown in Figure 1, adopt between shell script and host program and select steering logic output mode, realize mutual exclusion by selector switch 100 to switch, thus select to run host program 101 or Run Script program 102, selector switch 100 can be controlled by host program 101, also can be controlled by shell script.
As shown in Figure 2, sequential control logic output mode is adopted between shell script and host program, after the logic of host program 103 exports, increase selector switch 104, switch to by selector switch 104 the order actuating logic that ON position realizes host program 103 and shell script 105; When selector switch 104 switches to OFF position, host program 103 is Output rusults directly, and selector switch 104 is controlled by host program 103.
As shown in Figure 3, Parallel Control logic output mode is adopted between shell script and host program, when host program 107 runs, switch to ON position by selector switch 106 and realize shell script 108 and host program 107 parallel running, finally operation result is sent into simultaneously rear host program 109 (other subsequent control program), when selector switch 106 switches to OFF position, rear host program 109 receives only the operation result of host program 107.
When script compile, perform there is mistake time, the automatically out of service and throw exception code of shell script; Host program obtains shell script error code and processes mistake, arranges malfunction mark.
When shell script restarts operation, need first to stop all scripts to run, logic selector switch switches to OFF position; Then call lua_close function and close lua language running environment; Finally, re-execute initializtion script language environment and state, registration function, load source code, Run Script program.
