Directly copy ammeter: span is from the nearest a collection of purpose ammeter of collecting device, and the collecting device carrier signal can directly arrive;
Middle electromagnetic (type) relay: referring to have only by other ammeter forward signals because the purpose ammeter is far away apart from collecting device, could receive under the collecting device and signal, and pass the ammeter that signals to the purpose ammeter, is exactly middle electromagnetic (type) relay;
Route learning: the process that refers to ammeter is sought again the feasible path of checking meter.
Below be specifically described: see also two-dimentional midsequent automatic route meter reading method process flow diagram in Fig. 1 the present invention two dimension midsequent automatic route meter reading method and the carrier route dynamic maintenance method, as shown in Figure 1, described two-dimentional midsequent automatic route meter reading method comprises step: will treat that the first, the copy reading ammeter carries out layering step by step, and set up ammeter copy reading path; The second, treat in the copy reading ammeter selected first order ammeter information copy reading point described; Three, by each described first order ammeter information copy reading point corresponding second level ammeter under it is carried out copy reading; Four, by each described second level ammeter corresponding third level ammeter under it is carried out copy reading, by that analogy until the copy reading of finishing bottom ammeter; Five, each described data message of copy reading ammeter for the treatment of that described first order ammeter information copy reading point is collected gathers, and obtains each described data message for the treatment of that the copy reading ammeter is total.
Promptly directly checking meter for described first order ammeter at first order ammeter information copy reading point described in described second step also can be the ammeter data information collecting device.Described in a preferred embodiment of the invention first order ammeter information copy reading point is promptly directly checked meter for described first order ammeter.
See also two-dimentional copy reading mode configuration synoptic diagram in Fig. 2 the present invention two dimension midsequent carrier route dynamic maintenance method, the present invention carries out layering step by step setting with the described copy reading ammeter for the treatment of as shown in Figure 2, and the described of formation treats that the pattern of copy reading ammeter is two-dimentional formula.The construction method of this described two-dimentional formula is, with described same level setting is to extend along the longitudinal axis, and with described first order ammeter as directly checking meter, by the described second level ammeter of described first order ammeter copy reading as first order relaying, with the described third level ammeter of described second level ammeter copy reading as second level relaying, as N-1 level relaying, described second level ammeter to described N level ammeter is set at along transverse axis and extends by that analogy until N level ammeter, and with described N level ammeter.Shown in Figure of description 2, only set three grades of ammeters in an embodiment, but the present invention is not limited to only set these three grades, can extends according to the progression of actual conditions to ammeter along X direction.
We propose two-dimentional copy reading pattern, ammeter is carried out range, is transverse axis with the relaying degree of depth, is the longitudinal axis with same degree of depth ammeter, each ammeter is carried out the copy reading location again, directly copy ammeter 1 such as our copy reading, have only and directly copy ammeter 1 success, can follow the purpose ammeter that copy reading has this table relaying like this, copy reading is to secondary purpose ammeter, with three grades of ammeters of secondary ammeter copy reading, with three grades of ammeter copy reading level Four ammeters, the copy reading defective on the traditional mode can not appear like this.
According to a preferred embodiment of the invention:, the method for selecting of described first order ammeter is that the probe frame method is (promptly by the carrier communication agreement, read ammeter and support Data Identification, differentiate its whether normal communication successful method), and the described first order ammeter that will select is saved in successfully in the copy reading route information table as directly checking meter.On the basis that successfully searches direct copy reading ammeter, with direct copy reading ammeter is the transistroute basis, according to route relay selection distinguishing rule, be that successful copy reading sign, last copy reading successfully indicate, the middle electromagnetic (type) relay degree of depth, auxiliary distinguishing rule has modes such as ammeter table case, circuit number, ammeter phase information, according to the relaying principle, search eligible direct copy reading ammeter, directly copy the ammeter from searching out then, select the more excellent ammeter of directly copying as relaying, search can copy reading the next stage ammeter, preserve successful copy reading routing iinformation.
Described route relay selection discrimination principle is: middle electromagnetic (type) relay must have successfully the copy reading experience, and for the last time necessary successful copy reading; The middle electromagnetic (type) relay degree of depth must be the next stage of search ammeter; Middle electromagnetic (type) relay and purpose ammeter are not in the same ammeter box; Middle electromagnetic (type) relay and purpose ammeter are in same circuit; Middle electromagnetic (type) relay and purpose ammeter must be in same phase place.
On the basis of successfully searching electromagnetic (type) relay in the one-level, with electromagnetic (type) relay in the one-level is the transistroute basis, according to route relaying selection principle, search electromagnetic (type) relay in the eligible one-level, from the one-level that searches out, select in the more excellent one-level electromagnetic (type) relay then in the electromagnetic (type) relay as relaying, search can copy reading secondary ammeter, preserves successful copy reading routing iinformation;
According to the same manner, can successful three grades of purpose ammeters and multistage purpose ammeter such as level Four purpose ammeter, and preserve successful copy reading routing iinformation.
Concrete route learning flow process sees also Fig. 3, route learning process flow diagram in the present invention's two dimension midsequent carrier route dynamic maintenance method.
Need to prove: in algorithm, middle electromagnetic (type) relay just passes the generating table at the higher level of purpose ammeter, in transistroute, the purpose ammeter is only paid close attention to electromagnetic (type) relay among the higher level, and be indifferent to entire path.When middle electromagnetic (type) relay is selected, not only need suitably select the ammeter that meets the relaying demand according to the relaying distinguishing rule, and the satisfactory ammeter that can be used as relaying is carried out certain preferred, more reliable and more stable ammeter is wherein picked out, as the preferred middle electromagnetic (type) relay of purpose ammeter, can pick out a feasible relay route more efficiently like this.
See also carrier route dynamic maintenance method process flow diagram in Fig. 4 the present invention two dimension midsequent carrier route dynamic maintenance method.
Carrier route dynamic maintenance method comprises step described in the present invention: the ammeter of one, searching the copy reading results abnormity according to ammeter data copy reading result; Two, select middle electromagnetic (type) relay rank and carry out list table route learning again, if the failure of same rank ammeter route learning is then learnt electromagnetic (type) relay in the next stage of selected described middle electromagnetic (type) relay rank, circulation like this is up to the success of purpose ammeter route learning.
In described two steps, carry out again needing to extract historical routing iinformation internal information of statement as the foundation of seeking route again in the list table route learning process.Described carrier path is divided into check meter Breakdown Maintenance and two kinds of patterns of knot removal maintenance by Dynamic Maintenance; Wherein, the described Breakdown Maintenance of checking meter obtains feasible path again by re-routing mode of learning; Described knot removal is safeguarded and is adopted substitute mode, promptly re-route study by the purpose ammeter of the problem node being made nearest relaying, seek out a kind of new via node, replace described problem node with new via node then, and then re-route affirmation at the purpose ammeter of changing node.
See also the automatic copy reading schematic flow sheet of Fig. 5, as shown in Figure 5, copy reading is divided into following several state automatically: initialization, update mechanism, automatic data logging, study route, idle pulley and protection mechanism; Specifically described the handoff relation between each state in the drawings, will describe each state major function in system respectively below: initialization: when the main task flow process had just begun, carrier schemes, initialization Carrier State, application semaphore were confirmed in groundwork; Update mechanism: main task is loaded non-reset parameter, upgrades the ammeter data storehouse, obtains current state; Automatic data logging: main task is according to known routing iinformation copy reading ammeter information, when carrying out the copy reading task, in principle, according to two-dimensional approach copy reading ammeter, transverse axis is represented depth direction, and the longitudinal axis is represented same degree of depth ammeter, during copy reading, according to longitudinal axis reconnaissance, transverse axis extends copy reading, and copy reading can improve the copy reading success ratio greatly like this; Route learning: main task when on-the-spot occur because of complicated factor causes existing routing iinformation can't be successful during the copy reading ammeter, start updating route information mechanism; Idle condition: main task is finished the state that switches after the current task work when automatic data logging or route learning flow process; Protection mechanism: the main task internal system, can in time reset when unusual generation according to certain statistical information, keeps system works.
The automatic data logging cardinal principle: the mechanism of checking meter receives the application layer meter reading instruction, copy and accept the operation of ammeter data item according to foregoing description two dimension copy reading pattern, after copy reading flow performing one time, effect is copied and accepted in inspection, at copy and accept less than ammeter carry out corresponding route learning, then again copy reading last round of copy and accept less than project, so circulation finishes up to all copying and accepting.Enter idle pulley at last, the wait application layer is passed on meter reading instruction once more.
Be divided in automatic route and be several states: list is shown route, whole route, routing optimality, node updates and is stopped route.Concrete state can be consulted Fig. 6 routing state control chart, and in whole route link: the emphasis flow process is single table route; Concrete analysis is as the automatic route flow process of Fig. 3 list table, and single table route mainly contains following pattern:
Direct copy reading pattern: by copy reading particular meter data item, see and whether can correctly receive answer, confirm whether ammeter can normal communication.
Relaying copy reading pattern: by the information in certain differentiation ammeter routing infrastructure, whether differentiate ammeter for other ammeters are relaying, concrete distinguishing rule: modes such as ammeter success copy reading sign, last copy reading successfully indicate, the route degree of depth, ammeter table case, circuit number, ammeter phase information; When making route, in principle, the preferred same degree of depth and the higher ammeter of success ratio are made transistroute, and the purpose ammeter is only related with its higher level's relaying epiphase, does not consider the control of bypassing the immediate leadership, and be independently of one another.
In whole implementation process, whole route working model such as Fig. 7 specifically are divided into and stop route, single table route, overall route and routing optimality.Wherein the selective analysis routing optimality specifically comprises optimized choice and node updates, is analyzed as follows:
Optimized choice: in the carrier wave routing procedure, may occur a plurality of feasible routes simultaneously, how optimized choice, in this routing algorithm, optimized choice is proposed, in routing framework, introduce statistical mechanism, for each route adds statistical information, when choosing route and carry out the copy reading ammeter data, can select best routing plan, when re-routing study, can reject the poorest routing iinformation, then, its routing plan is carried out routing update, accomplish optimized choice.
Node updates: this is one can supply the external call interface, in kilowatt meter reading-out system, ammeter often occurs by turns, node updates seems most important in the route like this, because can accomplish that routing iinformation is complete by upgrading corresponding ammeter, avoid whole reroutings, also strengthened on-the-spot operability.
The present invention's two dimension midsequent carrier route dynamic maintenance method has following characteristics: one, under existing copy reading pattern, if according to unordered copy reading pattern, in case it is unusual node to occur, a large amount of meaningless time wastes can appear, efficient is comparatively low, adopt two dimensional model can avoid this situation to occur, for the plenty of time is saved in follow-up rerouting study.Two, the automatic route learning of carrier communication, this scheme will be avoided too many human cost, and system is after installation, collecting device can be sought feasible path to the purpose ammeter voluntarily, like this no matter site environment how, also need not on-the-spot line topological, as long as there is electric power transfer to get final product successful copy reading ammeter.Three, in automatic route learning, a kind of preferred relay scheme of nodes is proposed, this mode can make the via node of selecting more reliable and more stable, can be more stable by this category node copy reading purpose ammeter, and whole route via node is through optimized choice, convergence helps the management of system more.Four, route is from maintenance process, be that a kind of on-site experience is summed up, propose the unusual and two kinds of patterns of knot removal of node, make whole algorithm practical more, it is safeguarded the on-the-spot situation that may occur automatically with algorithm pattern, avoids dropping into more manpowers like this and safeguards the stable of carrier communication.Five, the present invention does not propose specific requirement to carrier schemes classification, communications protocol form and carrier-current relaying depth capacity, the tool quilt is extendability well, the whole series method is held layering thought well, the method only is concerned about data copy reading flow process, do not require that other aspects of program too much cooperate, and have good independence.
Beneficial effect of the present invention in sum is to compare with traditional meter register method, two dimension proposed by the invention is checked meter automatic route pattern can be so that check meter more quick, automatically search by purpose ammeter routing iinformation, make follow-up maintenance save trouble more, the realization difficulty is low, has higher utility.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some deduction or replace, all should be considered as belonging to protection scope of the present invention.
