Abstract
The invention discloses a real-time control system and method of a portable master station. A communication interface CPU sends task instructions to a task execution CPU through a task data register, task states are transmitted to a task trigger starting register through the task execution CPU, a task state double-port register and a task state reading register, task time is also transmitted to the task trigger starting register through the task execution CPU, a task time double-port register and a task time distribution register, the task trigger starting register triggers the task execution CPU for conducting task execution, the task execution CPU outputs a task execution result to the task data register, and then the task data register sends the result to the communication interface CPU for outputting. Parallel operation is carried out on the task execution state, time and trigger events according to parameters in a double-port cache, the relative stability of task distribution by the portable master station system is achieved, and the system and method have the advantages of being high in efficiency, good in performance and low in cost.
Description
Technical field
The invention belongs to electronic circuit field, relate in particular to a kind of real-time control system and method for portable main website.
Background technology
In the design of portable main station system, employing be that framework is controlled in multitask in real time, this framework mainly relies on that accurate clock time-sharing circuit completes.This just requires the relatively stable of task control in real time.
In actual field environment, because the electromagnetic interference (EMI) and the of high-frequency circuit own that are subject in work condition environment disturb, clock timing tends to produce deviation, causes timing unstable, cause the unstable of event task duty, when serious, can cause the collapse of whole portable main station system.
In this case, must in timing circuit, introduce parallel state processing mechanism, rely on stable twoport buffering, timing allocation task.
Summary of the invention
The object of the present invention is to provide a kind of real-time control system and method for portable main website, realize the relatively stable of portable main station system task distribution, there is efficiency high, the advantage that performance is good, cost is low.
A technical scheme that realizes above-mentioned purpose is: a kind of real-time control system of portable main website is provided, and it comprises:
Communication interface CPU is connected with task data register, sends the assignment instructions that this communication interface CPU receives;
Tasks carrying CPU is connected with task data register, reads described assignment instructions;
Task status twoport register is connected with described tasks carrying CPU, obtains the task status in assignment instructions;
Task time, twoport register was also connected with described tasks carrying CPU, obtained the task time in assignment instructions;
Task status reads register and is connected with described task status twoport register, reads task status;
Distribute task time register with described task time twoport register be connected, read task time;
Task triggering startup register reads register with described task status and is connected to obtain task status, is also connected to obtain task time with distributing register described task time;
Described tasks carrying CPU triggers startup register according to the described task being attached thereto and triggers to execute the task;
Described task data register obtains it task action result from described tasks carrying CPU, is sent to communication interface CPU output.
A technical scheme that realizes above-mentioned purpose is: a kind of real-time control method of portable main website is provided, and it comprises:
The assignment instructions of receiving is sent to task data register by communication interface CPU;
Tasks carrying CPU, from task data register read assignment instructions, is sent to task status twoport register by task status, also will be sent to twoport register task time task time;
Task status reads after the task status of register read task status twoport register, and output task status triggers and starts register to task;
Distribute task time after the task time of register read twoport task time register, output triggers and starts register to task task time;
Task triggers and starts register root according to task status and the task time of receiving, triggering tasks carrying CPU executes the task, task action result is exported to task data register by tasks carrying CPU, and then deliver to communication interface CPU by task data register and export.
Owing to having adopted real-time control system and the method for a kind of portable main website provided by the invention, state, time and the trigger event of tasks carrying is according to the Parameter Parallel operation in twoport buffer memory, realize the relatively stable of portable main station system task distribution, there is efficiency high, the advantage that performance is good, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
