Description

A kind of automatic continuous measuring system of rotary spherical digester temperature based on internet-based control

Technical field

The present invention relates to electric field, and in particular to a kind of rotary spherical digester temperature based on internet-based control, which is automatically continuously measured, is System.

Background technology

In pulping digestion process using alkalescence or Sulfates chemical agent, according to different type paper pulp the need for, to the greatest extent The lignin in plant fiber material may be removed, and retains cellulose and hemicellulose as far as possible, and makes frotation into slurry.In medicine While agent and raw material react, the lignin in raw material is not only removed, and resin, wax, the fat in raw material etc. is saponified and miscellaneous Cell is also removed therewith, while inevitably with the degraded of cellulose, hemicellulose.The reaction of digestion process as can be seen here Mechanism, key is the objective law for grasping digestion process exactly, reasonably formulates process conditions and in strict accordance with Process Planning Cheng Jinhang is operated, can effectively dissolved lignin, and protection cellulose and hemicellulose to greatest extent, acquisition height to reach The paper pulp of intensity, high yield pulp1.

In actual production, the maximum factor of influence pulp quality, paper pulp yield is digestion time, boiling temperature and had Imitate alkali concn.Due to participating in the complexity of the material (particularly lignin) of reflection in chemistry, and in digestion process Chinese medicine liquid The continuous change of composition, lignin shows three different duration of response, each duration of response have respective speed law and Stoichiometry.Three phases are:The delignification stage at initial stage:Delignification speed is mainly by diffusion rather than chemical action branch Match somebody with somebody;The bulk delignification stage:Chemical reaction is occupied an leading position:The residual delignification stage:Removing is remaining or hardly possible removes lignin.

In order to stably control pulp quality, preferable Kappa number, the effective alkali measured in the bulk delignification stage are obtained Concentration is used as mode input.Upright steamer or rotary spherical digester are when the controlled variable of digestion process is boiling temperature and boiling terminates Between, i.e., digestion process is stated by the H factors, stabilized it in setting value level.PREDICTIVE CONTROL is to produce in the later stage seventies One class novel computer control algolithm, this kind of algorithm is elapsed using the step of object or impulse response as model using rolling optimization To mode optimal control is realized to process online, show good control performance in complicated industrial process.Karr Graceful filtering is a kind of using linear system state equation, by system input and output observation data, system mode is carried out optimal The algorithm of estimation.Because observation data include the noise in system and the influence of interference, so optimal estimation is also considered as Filtering.Control system stably controls the temperature curve of digestion process using PREDICTIVE CONTROL and Kalman filtering, obtains The more accurate H factors so that the Kappa number that paper pulp is finally predicted is also more accurate.

Current maximum power control method is entered based on resonance coupling radio energy transmission system off resonance problem Row control, for example with phaselocked loop (PLL) technology, also have and the temperature division of radio energy transmission system in itself is coupled to resonance What phenomenon was controlled.Control method based on phaselocked loop (PLL) technology power output can only be adjusted in a small range, System is when much off-resonance temperature, and control method is ineffective.

The accurate measurement of rotary spherical digester temperature is very crucial to slurrying.

In summary, problems of the prior art are:In a wide range of, it is impossible to realize radio energy transmission system Maximum power transfer, control method is ineffective;Temperature error can not be obviously reduced in prior art, it is impossible to effectively improve process The control accuracy of system.

Step 2: selection cluster head:Whole detection zone is evenly dividing by grid, makes the size shape phase of each grid Together, the sensor node for selecting positional distance grid element center nearest in each grid is used as cluster head;
Step 3: sub-clustering:After the completion of cluster head selection, cluster head broadcast Cluster { ID, N, Hop } information, wherein, ID is node Numbering, the hop count that N forwards for Cluster information, and N initial value are the hop count that 0, Hop is default;Near cluster head Neighbor node receives N increases by 1 after Cluster information and forwards this information again, and until N=Hop, just no longer forwarding Cluster believes Breath;Again to Cluster information to be transmitted to the neighbor node of oneself after the neighbor node forwarding Cluster information of cluster head, then Send feedback information Join { ID, N, an Eir, dij, kiCluster information is transmitted to the node of oneself, most at last Join Information is transmitted to cluster head and represents oneself to add the cluster, wherein, EirRepresent the dump energy of the node now, dijRepresent two nodes Between distance, kiRepresent that the node can monitor the size of obtained packet;If a node have received multiple Cluster Information, node just selects the N values small addition cluster, if the equal nodes of N just at will select a cluster and are added to the cluster;If section Point does not receive Cluster information, then node sends Help information, adds a cluster nearest from oneself;
Step 4: cluster interior nodes constitute simple graph model:All nodes location in cluster in cluster is obtained by step 3, Each node is regarded and is connected between a summit of figure, each two adjacent node with side;
Step 5: in cluster weights calculating:By the step 3, cluster head obtains the E of member node in clusterir、dijAnd ki, calculate Weights between two adjacent sections point i, j, the calculation formula of weights is:
Wij=a1(Eir+Ejr)+a2dij+a3(ki+kj);
Wherein, Ejr、kjThe size for the data that node j dump energy and node j can be monitored, and a are represented respectively1+a2+a3 =1, such system just can be according to system to Eir、dijOr kiRequired proportion difference adjustment aiValue and be met difference The weights needed;
