Lock unit, be used for behind the acquisition state that receives described a plurality of data acquisition units, carrying out exclusive disjunction, when operation result is 0, send data acquisition signal to described a plurality of data acquisition units respectively, control described a plurality of data acquisition unit and carry out data acquisition.
Preferably, also comprise:
The a plurality of confirmation units corresponding respectively with each data acquisition unit are used for after described a plurality of data acquisition unit collections are finished, and send to described lock unit and gather the affirmation signal of finishing;
Described lock unit also is used for, is used for behind the affirmation signal that receives described a plurality of data acquisition unit feedbacks, this confirmation signal being sent to storage control unit,
Storage control unit is used for obtaining the image data of described a plurality of data acquisition units behind the affirmation signal that receives lock unit, and with data to storing storer into.
Preferably, described data acquisition unit is not in to gather in the process of waiting for and comprises: the pulse signal transmitting element does not send pulse signal, and pulse signal has sent pulse signal but data acquisition unit does not receive described pulse signal.
The beneficial effects of the utility model are: native system guarantees the synchronism that each collecting unit is gathered because lock unit is set, and has guaranteed the strictness alignment of the synchronism and the image data of each data acquisition unit, is convenient to the data analysis in later stage.
Description of drawings
Fig. 1 is the structured flowchart of first embodiment of the utility model multichannel rapid data collection system;
Fig. 2 is the structured flowchart of second embodiment of the utility model multichannel rapid data collection system.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of multichannel rapid data collection system comprises:
A plurality of data acquisition units are as the data acquisition unit among Fig. 11, data acquisition unit 2-data acquisition unit n;
The pulse signal transmitting element sends pulse signal to described a plurality of data acquisition units;
The a plurality of feedback of status unit corresponding respectively with each data acquisition unit, as the feedback of status unit 1 among Fig. 1, feedback of status unit 2-feedback of status unit n, be used for after described data acquisition unit receives pulse signal, obtaining the acquisition state of this data acquisition unit, described acquisition state comprises that being in the neutralization of collection wait process is not in the collection wait, when acquisition state is gathered in the wait process for being in, the feedback of status unit sends low level to described lock unit, do not bide one's time for being in to gather to wait when acquisition state, the feedback of status unit sends high level to described lock unit;
Lock unit is used for carrying out exclusive disjunction behind the acquisition state that receives described a plurality of data acquisition units, when operation result is 0, sends trigger pip to described a plurality of data acquisition units respectively, controls described a plurality of data acquisition unit and carries out data acquisition;
And, storer, described storer can be a plurality of storeies, the corresponding storer of data collecting unit, also can be a storer, the data that data acquisition unit 1-data acquisition unit n gathers all store in this storer, have provided the block diagram that has only a storer among Fig. 1.
When desiring to carry out data acquisition, the pulse signal transmitting element sends a pulse signal, if each data acquisition unit detect this pulse signal along look-at-me, be not to carry out the data acquisition operation immediately, but send to low level signal of lock unit, and do to gather and prepare.Lock unit inside is carried out logical OR unit and is calculated, guarantee only after all data acquisition units all send the low level confirmation signal, just send data acquisition signal, after each data acquisition unit detects this data acquisition signal, just carry out data acquisition, and draw high low level confirmation signal to lock unit.So just guarantee the strictness alignment of the synchronism and the image data of each data acquisition unit, be convenient to the data analysis in later stage.
