Communication link 102: realize the data communication between viewer and the board software viewer agency.Physically can be the physical link of PC and veneer transmission data, for example the RS232 interface of PC and veneer and the line between them; Except physical link, communication link also comprises the data communication module in the data communication module and board software on the PC that utilizes physical link to carry out data transmission and reception;
Board software viewer proxy module 103: receive the instruction that viewer transmits by communication link, according to the address of variable in the instruction, types of variables reads variate-value to address of variable; The variate-value that reads is formed response, be returned to viewer by communication link.
The viewer module comprises one of PC, operating system and operation software thereon, and PC and operating system are not introduced in detail here, mentions the software that viewer 101 refers to operation later on.It also comprises the board software global variable database of being set up by viewer 101 111, and being the user observes terminal with retouching operation to the board software variable.
Communication link 102 is finished the data transmission between viewer module 101 and the viewer proxy module 103, comprises Data Receiving and sending module on the PC operating system, Data Receiving on the board software and sending module, and physical link.Physical link is various informative, can be that PC goes up the line between RS232 interface on RS232 interface and the veneer and two interfaces, does not also introduce in detail here.
Viewer agency 103 finishes instruction and the execution that receives viewer, finishes the instruction back and responds.It is the part of board software, finishes the factorage of manager.
112 refer to that viewer module 101 sends data to communication link 102 among Fig. 1, carry out 123 finger communication links 102 then data are passed to viewer proxy module 103.132 finger viewer proxy modules 103 are passed to communication link 102 with data, carry out 121 finger communication links 102 then data are passed to viewer module 101.
Fig. 2 is fault analysis positioning flow figure of the present invention.At first be that step 201 fault takes place.Step 202 is decomposed into the flow process that breaks down the function f of concrete each performing step
1To f
n, n 〉=1 and be positive integer wherein.Step 203 is determined function f
m(the input variable X of m 〉=1 and m≤n)
MiAnd output variable Y
MoY wherein
Mo=X
(m+1) i, promptly go up the input that a step function is output as the next procedure function; X
1iRepresent the input of this system, Y
NoRepresent the output of this system.Fault is exactly Y
NoRefer to incorrectly, do not reach predetermined requirement.Step 204 is with m=1, promptly from first function f
1Beginning.Step 205 uses viewer to obtain X
Mi, how to obtain and in Fig. 3, to introduce in detail.Step 206 is judged X
MiWhether correct, if incorrect step 207 fault location that enters goes out input in system, native system itself is no problem, and flow process finishes; Use viewer to obtain Y if correctly enter step 208
MoStep 209 is judged Y
MoWhether correct, if incorrect step 210 fault location that enters goes out in function f
m, flow process finishes; Make m=m+1 if correctly enter step 211.Step 212 judges whether m equals n, if equate then enter step 213 fault location to go out at f
n, flow process finishes; Otherwise return step 208.
Fig. 3 is a viewer processing flow chart of the present invention, also is the specific implementation of step 205 and step 208 simultaneously.Step 301 program begins.Step 302 viewer 101 is derived the variable symbol table information text file with corresponding format according to the ELF file (having variable symbol table information) of board operation software, discern text file then and set up the global variable information database, database comprises the title of this variable, types of variables and address of variable.Step 303 viewer 101 receiving steps 205 or 208 the variate-value request of obtaining.The name variable that step 304 viewer 101 is checked according to step 205 or 208 needs, inquiry global variable information database is found out the address of variable and the types of variables of this name variable correspondence, and forms variable and observe instruction.Step 305 viewer 101 sends this instruction and passes through communication link 102 to viewer agent software 103.Step 306 viewer agent software 103 is according to the address of variable and the types of variables audit memory that contain in the instruction, copy one section memory address (length is determined by types of variables) that address of variable begins, and copy value (being variate-value) is sent to viewer 101 by communication link 102.Step 307 viewer 101 receives variate-value.Step 308 viewer 101 is notified the user, completing steps 205 or 208 with variate-value.
