From above-mentioned technical scheme as can be seen, the data that storage chip can storage of collected arrives need not manual record, therefore is applicable to and carries out pressure survey when unmanned.And after micro-control unit was waken up at interval with Preset Time, collecting unit etc. just were powered, and enter duty, thereby made each unit periodically or intermittently in running order, had further reduced power consumption, and whole registering instrument can be worked long hours.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is manograph structural representation that the embodiment of the invention provided;
Fig. 2 is another structural representation of manograph that the embodiment of the invention provided.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiment of the invention purpose is to provide a kind of tonometric manograph that carries out when being applicable to unmanned.
Fig. 1 shows a kind of structure of above-mentioned manograph, comprise that (its degree of protection can reach IP68 to waterproof case 1, thereby be applicable to abominable pressure measurement environment such as down-hole), be provided with pressure transducer 2 in the shell 1, storage chip 3, collecting unit 4, power supply unit 5 and CPU (central processing unit), above-mentioned CPU (central processing unit) comprises micro-control unit 61, real-time clock 62, wherein:
Real-time clock 62 is used for by supervisory circuit 63 timing wake-up micro-control units 61;
Collecting unit 4 is used to gather the simulating signal of pressure transducer 2 outputs, is translated into data;
When specific implementation, collecting unit can be gathered the pressure data of pre-determined number, gets the numerical value of wherein gathering several times and averages, and mean value is exported to storage chip 3 store.
The principle of work of each part mentioned above is: real-time clock 62 wakes micro-control unit 61 up by supervisory circuit 63 at regular intervals, and the micro-control unit 61 that is waken up power-on feed unit 5 after carrying out initialization makes storage chip 3 and collecting unit 4 enter duty.Subsequently, power cutoff feed unit 5, micro-control unit 61 enters dormant state with conservation of power.
In practice, during collecting unit 4 work, need be through entering steady state (SS) by non-steady state after a while, it is more accurate in the data that steady state (SS) is gathered.Therefore, during above-mentioned averaging, can be chosen at collecting unit 4 and enter (such as 4 times) several times data averaged that steady state (SS) records.When design, the time span that can make micro-control unit 61 be in work (or being waken up) equals Δ t1+ Δ t2, and wherein Δ t1 is the time span that collecting unit 4 plays pendulum, and Δ t2 is total duration in 4 sampling periods.
As can be seen, the data that storage chip 3 can storage of collected arrives need not manual record, therefore is applicable to and carries out pressure survey when unmanned.And after micro-control unit 61 was waken up at interval with Preset Time, collecting unit 4 grades just were powered, and enter duty, thereby made each unit periodically or intermittently in running order, had further reduced power consumption, and whole registering instrument can be worked long hours.
Each unit of manograph in the embodiment of the invention all adopts international advanced low-power consumption chip, extremely low with the complete machine Current Control.Especially the sampled idle time can hang down in 100 microamperes, only is equivalent to battery from loss.
In other embodiments of the invention, above-mentioned CPU (central processing unit) also can comprise supervisory circuit 63, is used for when micro-control unit 61 breaks down micro-control unit 61 being resetted.
In other embodiments of the invention, above-mentioned power supply unit 5 can comprise lithium battery.
Collecting unit 4 each samplings need certain current work, and under the certain situation of the electric weight of battery, sampled idle time length can prolong the working time of whole manograph.And can pass through above-mentioned real-time clock 62 to the setting of sampled idle time.For example, it can realize 1 second to 4 hours sampling interval.By the design power supply quiescent interval, the present invention can realize in 5 years 1000000 times sampling.
In order further to realize low power operation, in other embodiments of the invention, more than storage chip 3 among all embodiment specifically can be FeRAM memory chip.This chip has data holding time length, strong interference immunity, capacity and reaches advantages such as low-power consumption greatly.Chip storage capacity is 1Mbit, can store the 128K byte data altogether, merogenesis storage data, and every joint 1024 bytes can be divided 128 joints altogether, and every joint comprises that data head can store 502 spot pressures, amounts to 64256 data.
