Embodiment
The explanation of relevant embodiments of the invention is with reference to additional graphic, is used for the specific embodiment that illustration the present invention can implement.In following examples, in different figure, same section is to represent with same numeral.
Fig. 1 is the layer of structure synoptic diagram of the Flexible Measurement ﹠ Control plateform system of the embodiment of the invention, and Fig. 4 is the development approach schematic flow sheet of the Flexible Measurement ﹠ Control plateform system of the embodiment of the invention, the below according to accompanying drawing 1 by reference to the accompanying drawings 4 pairs of embodiment of the invention prove absolutely.Comprise hardware data collecting device 11 in the system of the present invention, be used for being connected and sending to the host computer of Flexible Measurement ﹠ Control platform with it multiport multi-protocols acquisition channel 12 of data; The host computer of Flexible Measurement ﹠ Control platform adopts the OO programming idea of Viusal C++ to write, and comprises that data collection layer 13, parameter arrange layer 14, data computation layer 15, data display layer 16, data storage layer 17 and data analysis layer 18; Data collection layer 13 be connected with hardware data collecting device 11 by multiport multi-protocols acquisition channel 12, its compatible various communications protocols and communication port, and can conveniently expand, not need too much consideration hardware collecting device compatibling problem when the user sets up test event; Data collection layer 13 is connected with data computation layer 15, data storage layer 17 and data display layer 16; Parameter arranges the output terminal that layer 14 is arranged at data collection layer 13, association attributes according to setting parameter, parameter is corresponding one by one with corresponding collection port, and call corresponding module, for example, equipment library 142(is referring to shown in Fig. 2) interior code, the data of corresponding collection port are made specific data in data computation layer 15 calculate, or without data computation layer 15, directly pass to data storage layer 17 or data display layer 16 to last layer; Data computation layer 15 is connected with data display layer 16, data computation layer 15 arranges the parameter call corresponding module that arranges in the layer according to parameter, for example, comprise modules such as being averaging computing module, data segmentation module, data counts module and data interaction module, the data that the data acquisition layer sends are calculated and processed, obtain unified frame format data behind the extracted valid data, and the data that will unify frame format are sent to data display layer and/or data storage layer; Data display layer 16 and data storage layer 17 interconnection, data display layer 16, data storage layer 17 are respectively applied to setting according to the user and show and/or store; Data storage layer 17 can arrange according to the parameter of the output terminal that is arranged at data collection layer 13 14 pairs of parameter of layer priority attribute is set, and high-speed data and low speed data are stored respectively; Data analysis layer 18 adopts the ADO technology, be ActiveX Data Objects, ActiveX Data Objects, it be the application programming interfaces that propose of Microsoft in order to realize the technology of the data in access relation or the non-relational database, reading out data carries out post-processed and the analysis of data from data storage layer 17.
As another preferred implementation, for data collection layer 13, the user can select gathering port and communication protocol according to test assignment and parameter demand, and under system framework, can drive by erecting equipment, the dynamic link library (DLL) of invocation facility adds new collecting device or communication protocol easily.If needed, the user also can test according to reality required, again writes data with existing and processes the interior data handling procedure of dynamic link library (DLL).Data collection layer 13 replaces actual instrumentation to improve dirigibility and the extendability of program, when test assignment changes, the user only need to get final product for the parameter that the test assignment Reparametrization arranges in the layer 14, promote so significantly the efficient of development and testing system, met the theory of flexible test; On the other hand, data collection layer 13 adopts the programming mode that is similar to virtual instrument, has significantly reduced the risk and cost for the hardware device change.
As another preferred implementation, the user can arrange layer 14 user-defined interface that provides by parameter, make one to one acquisition channel of parameter and collection terminal interruption-forming, thereby stipulate the parameter attribute of each acquisition channel, wherein mainly comprise frequency acquisition, port type, data packet length, triggering collection/circle collection type, priority etc.The user can arrange by parameter the priority attribute of the parameter of layer 14 setting, the high speed acquisition data are separated in different acquisition channels by multithreading from the low speed image data carries out, and be stored in the different database tables, thereby guaranteed the real-time that the hyperchannel big data quantity gathers.
As another preferred implementation, described data display layer 16, used teechart plug-in unit (Teechart, be the abbreviation of the controls such as Teechart for.NET, TeeChart Pro ActiveX V2010, the abbreviation by a series of chart controls of Steema company research and development) custom feature that enriches of the user that can provide, comprising whether data show in real time, data show control type, data whether preserve, in arranging one or more of each control property of display interface such as the position of data storage, storing frequencies.
Fig. 2 is the data multi-channel high-speed acquisition process synoptic diagram of the embodiment of the invention, and this schematic understands that the embodiment of the invention is for the implementation process that guarantees that multi-channel high-speed data gathers.Data are gathered by hardware data collecting device 11, then by multiport multi-protocols acquisition channel 12 data are passed to the data collection layer 13 of Flexible Measurement ﹠ Control platform; Because the present invention is general flexible test plateform system, for for different test assignments, offer setting and the operation of user flexibility, so parameter and port are not what fix, but by the parameter correlation attribute that arranges in the layer 14 is set in parameter, sets up the parameter that the parameter acquisition passage arranges the user and finish corresponding with the port of setting by calling the port respective modules; Wherein port type module 141 has been used the OO programming idea of VC++, in parameter layer 14 is set and offers the user-dependent option that arranges, select the port of its Data Source for each parameter that defines, like this, just make parameter and its Data Source realize " being flexible coupling " at data collection layer.
Pass through parameters 1, parameter 2, parameter 3 at data collection layer 13 ... the parameter acquisitions such as Parameter N are after corresponding data, just data are passed to data computation layer 15, this moment, " port type " attribute 141 and " other attributes " 144 modules of parameter just became the sign that the parameter call parameter arranges equipment library module 142 in the layer 14.Illustrate, for example, the Data Source of parameter 1 is serial ports, and comprise 3 valid data, the number of significant digit of each data is 8, in parameter layer 14 parameter that provides being set so arranges the interface and has corresponding attribute for user selection, then carry out data acquisition according to the good serial ports baud rate of these setup of attributes, and in data computation layer 15 by calling corresponding module, for example code or the function of equipment library module 142 interior correspondences, the data source of this parameter is divided into 3 minutes by zone bit, and extract every part 8 for valid data.Again for example, parameter 2 is flexible coupling with the count value of the counter transmission of CAN bus, because parameter is timing acquiring, so need the data that obtain in the timing cycle calculating of averaging, then can set a property according to parameter correlation, code or the function of invocation facility library module 142 interior correspondences calculate this data value of averaging, thereby obtain effective value.In addition, data computation layer 15 is set as unified form with all valid data, so that follow-up data are processed storage and demonstration; The theory of equipment library module 142 is compared with having calculating now, has guaranteed versatility, the compatibility of system, and expansion is convenient for the programmer, only need set up the zone bit that calls, and reaches correlative code or function and gets final product.
Supplemental characteristic obtains unified frame format data after data computation layer 15 is processed, then according to priority attribute, the priority block 143 of layer in 14 is set with different priorities by parameter, be that the data of different acquisition speed are divided into different passages and transmit to the upper strata, only represent two passages in the synoptic diagram, but when reality is used, can open a plurality of passages to the setting of priority level according to the user.As an example, describe with two passages shown in Figure 2, if the priority of certain several parameter is high, then by calling high speed timer timeSetEvent function and high-resolution counter QueryPerforman ceFrequency function carries out, set up a high speed data transfer passage, the collection period of this passage is very short, is generally Millisecond.Simultaneously at parameter display layer 16, curve display module 161, digital display module 162 and the instrument display module 163 that can provide according to real-time display interface shows in real time by user's setting, at a high-speed data stored data base of data storage layer 17 dynamic creations table 171, be used for receiving the high speed acquisition data.The data that priority is low, what then timer timeSetEvent function and high-resolution counter QueryPerformanceFrequency period of a function value are arranged is larger, for example, be arranged to 500ms, also can show in real time according to user's be arranged at curve display module 161, digital display module 162 and 163 connections of instrument display module simultaneously, at a low speed data stored data base of data storage layer 17 dynamic creations table 172, be used for receiving the low speed image data.In addition, also should adopt the circular buffer technology at the low speed passage, with the loss of data of avoiding the lower low speed acquisition channel of priority to cause owing to thread block.Compared with prior art, the present invention has guaranteed the hyperchannel big data quantity collection of system by said method.
Especially, curve display module 161 in the data display layer 16, digital display module 162, instrument display module 163 and other arrange module 164, have can add, drag, edit, the feature operation such as deletion, rich and varied user's operation is provided, has demonstrated fully the characteristics of flexible test technology.
As preferred implementation, because that the high speed acquisition data volume reaches more greatly user operation is too frequent or take resource when too much, low speed image data priority is lower, then may result in blockage to low speed collecting thread passage.And meanwhile, just have from data collection layer to this low speed thread acquisition channel to send data, will be omitted by other data processing threads at certain one piece of data of sending during this period of time that stops up so, thereby caused losing of data.Can adopt the circular buffer technology in order to address this problem us, the longest data of length that soon may collect, the data length that sends to data low speed collecting thread passage each time as the tentation data collecting device, then create a buffer queue according to this length, be used for the data that the storage of collected thread sends.In a single day low speed collecting thread passage obtains resource, and namely the user operates to reduce or do not take when resource is not a lot of and begins this segment data is processed.In code, want to realize the simplest way of buffer queue, set up exactly a similar ReadBuffer[Count] two-dimensional array of [DataLen], with the DataLen in the array, be the data that lateral length is considered as the maximum length that each low speed collecting thread passage may send, with the Count in the array, namely vertical size is considered as member's number of buffer queue.Size and actual operating position according to data are come this array is set.
Fig. 3 is the low speed channel cycle caching technology synoptic diagram of the embodiment of the invention, as shown in Figure 3, in use, we with maximum each time image data length as benchmark, preferably, in this test environment, with the basic storage unit of double categorical data as buffer zone, get so the horizontal storage space that 30 such unit just enough guarantee data, vertical storage unit number with buffer queue 22 is set as 32 in addition, so in fact ReadBuffer[32] form of [30] this array is buffer queue 22 described above.Data acquisition thread 21 and data processing threads 22 are respectively by changing the value of ReadCount and StoreCount, fill the address value of dynamic pointer and change the data buffer of pointed, and the length of each buffer zone is identical, all be DataLen, in order to prevent interfering with each other, we use two variablees, and namely ReadCount and StoreCount store respectively the pointer subscript variable of data acquisition thread 21 and data processing threads 22.Work as collecting device, after the initialization such as serial ports, CAN, the data acquisition thread is namely started working, when carrying out data acquisition for the first time, value that will ReadCount is set to 0, namely is that pointer points to first buffer zone 221, and carries out the data receiver of collecting device with this buffer zone.After one piece of data has gathered, send corresponding message by the message corresponding modes to the data processing threads, the SegIndex variable added 1 (the SegIndex variable was the public variable of two threads this moment, this variable has recorded because thread stops up, the data acquisition thread collection that causes and the buffer zone number that sends to the data processing threads, carried out the difference of the buffer zone quantity that data process with the data processing threads, and there is not processed buffer zone number after gathering), then ReadCount will add l certainly, make second buffer zone 222 of pointed, use this buffer zone that data are gathered.Then SegIndex is from adding 1, and so circulation is carried out, and when the ReadCount value equals 3l, this value is reset, and makes the start bit of pointed buffer zone, restarts access.And for the data processing threads, then to pass through event response process of SetEvent () function setup, after every secondary data is stored in buffer zone, send a message, after this thread receives message, the buffer zone number of not carrying out the data processing because thread stops up is judged, then when the thread Gains resources, carry out processing one by one, one of every processing, SegIndex variable be from subtracting 1, until SegIndex represented that buffer zone had not had untreated data at 0 o'clock.Therefore, load suddenly when increasing when the test macro program, we can at first guarantee data acquisition speed and collecting efficiency, and under the assurance of the buffer action of buffer zone formation, the data processing threads needn't be processed in real time to data.Image data is buffered in the buffer zone continuously by collecting thread in this case, and carries out the buffer memory of certain hour, can not cause loss of data because of the obstruction that data are processed line like this.Use this technology, can also be to the value of the public variable SegIndex of two threads real-time judge in addition, if its value is greater than 32, then certainly because test procedure is too busy, cause data processing threads duration of congestion to exceed the scope that allows, this moment, buffer zone overflowed, and can remind operating personnel by the mode of reporting to the police.Therefore adopt this technology so that the fault-tolerant processing ability of test procedure is improved.
The embodiment of the invention in a kind of performance history of Flexible Measurement ﹠ Control platform, has incorporated the thought of " flexible test " technology for traditional monitoring platform system and the defective of development approach.The thought of flexible test is mainly reflected in following at least one aspect: (one) data collection layer, compatibility with multiport multi-communication protocol, can support the input of multiple collecting device, the user can define flexible development and growth data acquisition layer according to system framework, thereby develops corresponding test macro for different test assignments; (2) parameter arranges layer, and the flexible custom feature of using is provided, and parameter and acquisition channel is flexible coupling, thereby guarantees the fast Development of new test assignment; (3) multithreading of use Windows adopts multimedia high speed timer timeSetEvent, high-resolution counter QueryPerformanceFrequency and circular buffer technology, has realized the multi-channel high-speed collection of data; (4) use Visual C++ object-oriented programming method and teechart plug-in unit, the user can self-defining data subsequent treatment, comprise whether instant playback of data, whether data preserve, the data storing frequencies, the control type of display interface, the setup of attribute of each control etc., the purpose of realization flexible setting.
The embodiment of the invention is by data collection layer and collecting device and port communication, carry out data acquisition according to configuration information, then the allotment that by parameter layer is set is carried out data and is calculated, then sending to the data display layer shows, the operations such as warning, control are stored at data storage layer simultaneously.The present invention has overcome the defective of legacy test system, satisfied the demand of modern test assignment, improved the efficient of refresh test task, reduced the risk and cost of system development, the introducing of flexible test technology has solved the problem of legacy test system extendability, dirigibility deficiency.
Foregoing is to comprehensive explanation of the present invention, and should not be construed as a limitation of the present invention.Should be pointed out that for those skilled in the art without departing from the inventive concept of the premise, can also make some improvements and modifications, these improvements and modifications also should be considered within the scope of protection of the present invention.
