Non-interrupted formula described in any of the above embodiments and pseudo- parallel embedded software real-time response method are realized when sequence is executed by processor
Step.
Below by preference, the present invention is more specifically illustrated.
Embodiment 1:
A kind of non-interrupted implementation method of multipriority input
As shown in Fig. 2, multipriority input is non-interrupted to realize that steps are as follows:
Step 1: single-chip microcontroller electrification reset carries out program initialization.After single-chip microcontroller electrification reset, in program initialization part
All input/output end port types of single-chip microcontroller are configured, to output end poll tax on children initialization value, configuration software system tick timer,
The setting system suitable clock cycle realizes that non-interrupted real-time response sets response time element factor to be subsequent.Setting program
All kinds of interfaces include communication interface parameters, such as serial ports transmission rate, data format check code.
Step 2: program scan round is carried out.According to priority orders, each program module is scanned.Single-chip microcontroller does not operate
System, therefore program scanning can only successively be carried out according to sequencing.Programmer should accurately determine the excellent of each program module
First grade, and according to the order-assigned of priority from high to low into the circulation of program scanning.It is same when carrying out priority judgement
Each submodule of priority should be classified as a program entry, to reduce the scan period, improve executing efficiency, enhancing program is rung
Answer real-time.
Step 3: input data is received.The input data received is handled, including Key dithering, anti-error behaviour
Make.Here a kind of single-chip microcontroller input signal de-jitter method is described.By being sampled three times to input signal array X [V], three
Secondary sample states unanimously think that input effectively, otherwise in vain, effectively avoids maloperation.
void FreshX(void)
{
int V；
For (V=0；V<8；V++){
LastX [V]=X [V]；
X3 [V]=X2 [V]；
X2 [V]=X1 [V]；
}
For (V=0；V<8；V++){
X [V]=(X [V] & (X1 [V] & (~X2 [V]) | X2 [V] & (~X3 [V]) | X3 [V] & (~X1 [V]))) | (X1
[V]&X2[V]&X3[V])；}
}
Step 4: according to priority, input signal is responded.According to input signal priority, responder is called to handle mould
Block realizes program function.The sequencing that different priorities input responder entrance is controlled by IF, ELSE statement.
As shown in Figure 1, each software module function is clear, module is relatively independent, and the data exchange of intermodule is become by global
Amount transmitting, reduces the access to local variable in module, improves software execution speed and efficiency.Below with one section of program example into
Row explanation.Wherein
Embodiment 2:
A kind of pseudo- parallel real-time response design method
What example 1 illustrated is realized to the control of multipriority input and non-interrupted mode, is illustrated in example 2 pseudo- parallel
Real-time response implementation method.
Step 1: being the real-time and reliability for ensuring software in software design procedure, using the software systems of single-chip microcontroller
A suitable clock cycle is arranged, as the fundamental clock factor of a software responses, such as 50ms in clock timer.
Step 2: program design.Software main program is after having carried out electrification reset, self-test and program initialization, into one
A scan round structure realizes that main program continually scans for each input port using While sentence, according to input and preferential grading
Enter disparate modules, after the completion of waiting current blocks to execute, still enters main program and scan.
Step 3: each program respond module puppet Parallel Implementation.To realize the response of high priority real-time priority, it is impossible to wait one
A low priority modular program enters back into high priority module inlet after the completion of executing and is responded, and thus loses in real time
Meaning, therefore each program execution module is divided into several steps according to step number is executed, each step is jumped out immediately after being finished
Current sub-routine processing module, and subroutine module is currently executed into step number as return value, it is defeated to enter major cycle progress later
Inbound port scanning, when there is the higher input of priority to need to respond, into high priority responder entrance；If without more
The input of high priority is requested, and is entered current sub-routine module according to step number is executed, is performed the next step program.It is this pseudo- parallel real
When response need to execute step number and software timer by setting global variable, and realized by switch, case cooperation.
It gives one example and is illustrated below.Assuming that a software module such as " land and water operating condition " is made of several steps, such as Fig. 3
It is shown.Each input port of program circulating scanning system, if the system detects that then executing " land and water into " land and water operating condition " signal
The first step of operating condition " subprogram, sets delay mark backed off after random, and system continues to execute system major cycle downwards；If " land and water work
Condition " delay is arrived, and the second step of " land and water operating condition " subprogram is executed, and sets delay mark backed off after random；System continues to execute system downwards
Major cycle.Repeatedly, until " land and water operating condition " is finished.Other operating condition executive conditions are also such.
When the delay of land and water operating condition back off timer _ Timer_Of_WaterLandStatus to after, into timer T2
Disconnected processing function, is handled and is controlled to the loop control variables such as step number S, delay variable are executed, complete each module of system
Execute control and calling process.
Step 4: response time control is realized in main program.Response time control is realized by periodically in major cycle,
By adjusting basic chronon and timing control response speed.

Real-time response designing system includes: the puppet parallel
Timer setting module: the software systems clock timer is used, optimal timing unit is set, as software responses
The fundamental clock factor；
Program design module: design software main program enables software main program to have carried out electrification reset, self-test and program initial
After change, into a scan round structure, main program is enabled to continually scan for each input port, difference is entered according to input and priority
Module still enters main program and scans after the completion of current block execution；
Pseudo- parallel real-time response realizes module: each program respond module puppet Parallel Implementation enables each program execution module according to execution
Step number is divided into several steps, each step jumps out current sub-routine processing module immediately after being finished, and by subprogram mould
Block currently executes step number as return value, enters major cycle later and carries out input port scanning, it is higher to judge whether there is priority
Input when needing to respond: if so, then entering high priority responder entrance；Otherwise, then enter according to execution step number current
Subroutine module performs the next step program；
Response time control module: response time control is realized in main program, realizes response by periodically in major cycle
Time control, by adjusting the fundamental clock factor and program timing time control response speed.
9. a kind of computer readable storage medium for being stored with computer program, which is characterized in that the computer program is located
Reason device realizes non-interrupted formula described in any one of Claims 1-4 and pseudo- parallel embedded software real-time response side when executing
