File is to local hard drive and is sent to storage equipment realization data double copies function.
Embodiment
The present embodiment is acquisition and store method based on the miss distance data under vxWorks real-time system, is used to lead
Play acquisition and preservation of the Miss distance measurement equipment to miss distance data in Targeting.
Miss distance measurement equipment in the present embodiment, bottom hardware are the programmable logic device that can carry out digital processing,
The V5 SX95T fpga chip of a piece of Xilinx company is used in the present embodiment, upper layer uses vxWorks real time operating system.
In vxWorks real time operating system, the bridge that data interaction is carried out with system bottom hardware is PCI9056 bridge.For data
The correctness of transmission needs to have a synchronization signal between sender and recipient, and the present embodiment interrupts to realize number using PCI
According to acquisition, need under vxWorks operating system develop device PCI driving, come respond PCI interrupt, carry out pci bus on
Real-time Data Transmission, data transmission use DMA mode.
Human-computer interaction interface is developed on far control host, this human-computer interaction interface is mainly used to send out to Miss distance measurement equipment
The command signal for sending log-on data to acquire.Exploitation saves the program of data on remote storage device, is mainly used to receive acquisition
Backup of the data and preservation arrived at file, as miss distance data.
2.8G continuous wave signal is injected to Miss distance measurement equipment with line feedback injection mode, it is remote to control host and storage equipment point
Miss distance measurement equipment is not connected to by cable.PCI responds interrupt cycle as 1ms, and it is collected every that each PCI interrupts generation
Frame data have been put into buffer queue, and every frame data amount is 8K Bytes, multiframe data volume can be stored in buffer queue, as slow
The size for depositing queue can be configured according to performance requirement, realize the buffering between data acquisition and data rate memory.?
Task is independent there are two creations under vxWorks system, runs parallel, and written document is to originally after a task receives buffer queue data
In ground hard disk；Another task receives buffer queue data and is sent to remote storage device by network, and storage equipment receives net
Network data simultaneously save as file；And there is a timed task to send Miss distance measurement equipment state in real time to man-machine under vxWorks
Interactive interface.
Specific step is as follows for data acquisition and preservation process:
(1) the human-computer interaction interface confirmation Miss distance measurement equipment of far control host normally starts；
(2) command signal for starting to acquire and sending log-on data acquisition by twisting Miss distance measurement equipment is clicked；
(3) log-on data acquires under vxWorks system in Miss distance measurement equipment, shown in Figure 2, and initialization PCI is interrupted, root
It is interrupted according to PCI interrupt number carry PCI, the PCI that latent period is 1ms, which is interrupted, to be generated；
(4) PCI, which is interrupted, generates, and data acquisition passes through pci bus the bottom of from referring to Fig. 3, interrupting starting DMA in service function
Layer acquisition 8K Bytes miss distance data, data terminate DMA after running through, collected miss distance data are put into buffer queue
In, the period of a reading data completes；
(5) referring to fig. 4, the local for writing 8K Bytes data to Miss distance measurement equipment from buffer queue is hard for data storage procedure
Disk；
(6) 8K Bytes data to remote storage device is sent from buffer queue by network simultaneously to save；
The period of (7) storing datas completes, and repeats step (3) and continues waiting for PCI interruption generation；
(8) human-computer interaction interface of far control host, which is clicked, stops acquisition button, the acquisition of Miss distance measurement device end data.
The present invention interrupts to start the acquisition function that DMA data transfer realizes miss distance data by response PCI, by writing
File is sent to storage equipment to local hard drive and network and realizes data double copies function.
Correspondingly, the present invention provides a kind of acquisition and storage systems of miss distance data, characterized in that include:
