When to ensure the real-time between external equipment and host equipment, action is performed between external equipment and host equipment so as to improve
Uniformity and accuracy.
Wherein, task requests include data receiver task, receive data processing task, data sending processing task and number
According at least one of transmission task.Specifically：
Data receiver task can be established by RTOS, receives data processing task, data sending processing task and number
According to the task of transmission, in addition to this it is possible to establish other inter-related tasks.RTOS can create task by mission function, and should
Mission function for example can be C language function.One mission function can be used for creating several tasks, and be created that each
Task is independent execution example, possesses one's own stack space and one's own stack variable, i.e. mission function
The variable of definition itself.
Data receiver task refers to that system needs to receive the pending data sent from external equipment by function；Receive number
It refers to that system needs to receive from what external equipment was sent by function according to processing task to what pending data was handled to appoint
Business, data sending processing task refer to that system needs to send to external equipment by function and appoint to what some data were handled
Business, data sending task refer to that system needs to send pending data or processed data to external equipment.Wherein, number
It can for example include data deciphering, Data Format Transform, data encoding conversion etc. according to processing；The system of host equipment can basis
Received task request instruction handles associated data accordingly.
In the step s 120, the pending data is stored to default memory sequence according to the type of the pending data
Row.
In this example, the type of pending data can for example include the data sent for the first time, wherein can include variable
Type data can also include the data of the types such as numeric type, text-type, byte type, and in addition, the type of pending data is also
It can include needing the above-mentioned various types of data resend.
Wherein, the default memory sequence can include in variable memory sequence, datarams sequence and retransmission data

Property, thus when stand-by period when can recover to avoid system and system crash may caused by loss of data situations such as, into
And improve the efficiency and accuracy of data transmission.
Specifically, handling the task requests in real time by the default memory sequence can include：By described pre-
If memory sequence, using each task requests of blocking mechanism Real-Time Scheduling.
The implementation procedure of each task requests can be seen as a process, and blocking mechanism refers to not getting
During task requests, the process that the process that can hang up is suspended simultaneously enters dormant state, until getting task requests, this
When can give the corresponding cpu resource of the process to other processes.By default memory sequence, RTOS is realized using blocking mechanism
To the Real-Time Scheduling of multiple tasks request, the operation that can be asked to avoid continuous query task reduces and disappears to cpu resource
Consumption, effectively increases CPU efficiency, while improves the utilization rate of hardware resource.
In addition, handling each task requests in real time by the default memory sequence can include：In processing institute
Apply for the default memory sequence before stating task requests；And/or discharge the default memory sequence after the task requests are handled
Row.
In this example, host equipment carries out data transmission can be understood as the communication function of host equipment with external equipment,
This communication function is one kind in electric welding machine repertoire, therefore in order to avoid the influence to other functions, communication function
The memory sequence space of predefined can only be used to carry out.At the same time, in order to avoid influencing each other between multiple functions, hold
The memory sequence space that communication function can not be used to use during other functions of row.
It,, can be in processing received task in order to avoid the deficiency of memory headroom when performing communication function based on this
Memory sequence is preset in the forward direction system application of request, such as can be according to pending data type application variable memory sequence, number
According to part or all of in memory sequence either retransmission data memory sequence.For example, need what is sent for the first time in processing
During data, it can only apply for variable memory sequence or datarams sequence, can also apply for variable memory sequence and data simultaneously
Memory sequence.
Further, the deficiency of memory headroom can also be avoided by way of discharging default memory sequence.It such as can be with
After the request of default memory series processing received task, the default memory sequence being not used by is discharged, so that this is default
Memory sequence may be reused, and showing for caused by low memory system crash is avoided while its utilization rate is improved
As.
It should be noted that it can only apply for default memory sequence before the task requests are handled；Can also only it locate
The default memory sequence being not used by is discharged after managing the task requests；It can also apply for default memory before task requests are handled
Sequence simultaneously discharges default memory sequence after task requests are handled, and specifically can specifically be set according to actual demand using which kind of mode
It puts.
You need to add is that the data transmission method described in this example can also include：Using data block mechanism each
Data are transmitted between the task requests.
Wherein, data block is the one group or several groups record of continuous arrangement together in certain sequence, be main storage with it is defeated
Enter the data unit being transmitted between equipment, output equipment or external memory.The size of data block can be fixed, and also may be used
It is configured and divides with factors such as input, the memory spaces according to data.Each data block can correspond to a logic note
Record, can also include multiple logic records；A logic record can also be represented by multiple data blocks.For example, if
Data line is common row, then this row data can be stored in a data block；If data line is chained line, this row
Data are stored in multiple data blocks.Carry out data transmission by using data block mechanism between multiple tasks request, it can be with
The data transmission confusion phenomena generated when performing communication function between host equipment and external equipment is avoided, so as to ensure that data pass
Defeated accuracy and reliability.
