The military antitank missile power source special module detector of the utility model, its high speed of PC104 computer are accurate Acquisition similarly, tracks AD conversion progress using sub thread with ISA, device PCI, and carries out data acquisition and be to maintain data continuously not Intermittent preferred plan；But unlike isa bus equipment, PM511PF equipment does not use dynamic pointer herein and goes together AD conversion progress is walked, because the dynamic pointer operation of ISA device annular memory pool is a kind of synchronization of software implementation, and PM511PF There is no the synchronizations of software implementation for equipment, and are automatically performed completely by hardware and driver；So, it is realized with program mode (PM) Continuous data acquisition, software realization, which just seems, to be relatively easy to, but since equipment is usually to work in a list CPU multitask Environment in, due between task scheduling switching it is very ordinary, especially when display indicator light, data or pop-up dialog box When, current thread can be made to use up a large amount of time and go to handle these graphic operations, so if dealing with improperly, then will be unable to realize Data high-speed continuously continual acquisition；For this purpose, being completed using data acquisition thread, simultaneously, it is desirable that this thread is absolute Worker thread, i.e. this thread cannot have any window graphics operations in normal acquisition；When occur indicator light, data, Or when pop-up dialog box, this thread is not plugged up, and guarantees normal continuous data acquisition；But it not can be carried out any window Operation, for how to be displayed on the screen the data of acquisition, by test of many times, using opening up a data processing sub-line again The problem can be solved in journey, i.e. user-interface thread；Initially, data processing threads do not do any work, but in Win32API Enter sleep state under the action of function WaitForSingleObject, it does not consume CPU any time at this time, that is, can guarantee Other thread codes such as data acquisition line have adequately operation chance, when data acquisition line journey obtains the data of designated length, Specified event message is then sent to data processing threads with Win32API function SetEvent again, then data processing threads are at once It resumes operation state, this batch data is handled rapidly, such as calculate measurement result, show measurement data, emergency warning lamp in window The operations such as display, preservation operating result；Since data acquisition line journey is ceaselessly acquiring data, and data processing threads are non-works Author's thread, when the operation of the display windows such as measurement data plugs the thread, therefore data processing threads will lose number The one piece of data sent according to collecting thread, for this purpose, the design scheme of first-level buffer queue and level 2 buffering queue is used, to keep away This problem is exempted from, i.e. hypothesis data acquisition line journey takes out 8K data from equipment each time, then we are created that one is delayed Queue is rushed, a bidimensional array such as PADBuffer [Count] [DataLen] is opened up, DataLen is considered as data acquisition line journey The data length acquired every time, Count are then the membership of buffering queue；According to usual computer physical memory size and always Body service condition sets this number；32 are set as, then this buffering queue is actually [32] [8192] array ADBuffer Form；It is similar with a common buffer area such as one-dimension array, is not uniquely both, and two threads first have to pass through change The value of Count field, the i.e. value of this subscript Index are directed toward a certain section of DataLen length by Index subscript to fill and quote Data buffer zone；When data acquisition line journey initializes it by InitDeviceProAD or InitDeviceIntAD in AD component Afterwards, when acquiring data for the first time, then the ReadIndex subscript of oneself is set to 0, i.e., acquires AD data with first buffer area；When After having acquired, then message is sent to data processing threads, and the public variable SegmentCounts of two threads adds 1, then again Then ReadIndex is offset to 1, then acquires data with second buffer area；SegmentCounts is added 1 again, until arriving Until ReadIndex is equal to 15,0 position is then returned, is restarted；And data processing threads are then receiving message every time When judge how many due to self be blocked without processed buffer area number, then handled one by one, finally again from Handled buffer area number under the current event received is subtracted in SegmentCounts variable；Even if in this way, using Program is extremely busy suddenly, the data for making data processing threads not have time-triggered protocol to arrive, but due to the buffering of buffer queue Effect, can allow data acquisition line journey first continuously to cache data in this region, since this buffer area can be designed Bigger, therefore can buffer the time that graph data is shown, even data processing threads are numerous occasionally due to system in this way Busy face is blocked, it is also difficult to make missing measurement, therefore have the function of powerful fault-tolerant processing, solve display operation and number According to the problem of acquisition real-time perfoming.
