Description

A kind of interactive system of the experimental facilities Automatic Control based on remote control
Technical field
It is complete certainly that the invention belongs to experimental facilities control technology fields more particularly to a kind of experimental facilities based on remote control The interactive system of dynamic control.
Background technology
Currently, the prior art commonly used in the trade is such:
Experiment, is one of basic skills of scientific research.According to the purpose of scientific research, extraneous shadow is excluded as much as possible It rings, prominent principal element simultaneously utilizes some special instrument and equipments, and artificially changes, controls or analog study object, makes certain Some things (or process) occur or reproduce, to go to know natural environment appearance, natural property, the natural law.However, existing experiment Equipment cost is high, and quantity is few, cannot meet a large amount of users and use;When equipment fault simultaneously, hand inspection is repaired, and can not only be spent Take plenty of time and maintenance expense, malfunction elimination is difficult.
Network generally selects low cost, low-quality node, causes the collected data of sensor institute that can have many mistakes Difference data, wrong data, inconsistent data possibly even lose data.There are so many for data collected by sensor node Corrupt data is so that it can not be used directly to scientific research.For this purpose, in order to preferably use WSNs data, while for reality Its existing various functions, being detected to the exceptional value in network becomes increasingly important.
Currently, having there is multiple rejecting outliers method:Method based on adjacent node is based on statistical method, base In the method for sub-clustering, the method based on cluster and the method based on spectrum analysis.But some of sensor network itself are special Point is so that not all existing detection method can be well directly used in wherein.For this purpose, in order to preferably design about Efficient, the feasible rejecting outliers method of WSNs needs to consider following characteristics:
(1) node capacity is limited.The cheap miniature characteristic of sensor node causes the energy of its carrying power supply fairly limited. The number of energy affects the processing, storage and transceiver communication ability of sensor node to a certain extent.Therefore, it is actually answering In, it should fully consider the various energy and energy power limit of sensor node, however most traditional detection methods seldom consider Performance of the algorithm in the case where node capacity is limited.
(2) distributed ad-hoc.In WSNs, all nodes are in identical status, and none of node is tight " ruler " in lattice meaning, it is that it can guarantee by distributed collaborative that the equality between this network node, which directly affects, The normal operation of network.Meanwhile the node of WSNs has very strong self organization ability, it can be in any severe or dynamic ring Configuration network under border, and the monitoring data person that sends remote observation to is realized by the function of network by specific approach.Consider net The superpower self organization ability of network can reduce network overhead very well, to design more effective rejecting outliers algorithm
(3) high energy consumption high load.The wireless communication of wireless sensor network node can consume most of energy of node, It is a lot of times that node calculates consumption.However, side of most tradition rejecting outliers methods using the collected data of centralized processing Method considerably increases node energy consumption and traffic load, reduces network life.Therefore, communication energy consumption can how be reduced to extend The WSNs service life is the important consideration aspect for designing WSNs rejecting outliers methods.
(4) real-time.The application field of comprehensive analysis WSNs can obtain, be required for the detection of exceptional value online and real When.Network is directly proportional to the reaction time of event and the performance of system.Therefore, design real-time rejecting outliers method be and its It is necessary to.
In conclusion problem of the existing technology is:
Existing experimental facilities is of high cost, and quantity is few, cannot meet a large amount of users and use;When equipment is out of order simultaneously, people Work inspection is repaired, and can not only be taken a significant amount of time and maintenance expense, malfunction elimination difficulty.
In real time, distributed while relatively low communication energy consumption and traffic load can be kept, and may be implemented compared with high detection The rejecting outliers method of rate and relatively low rate of false alarm is to be suitble to the rejecting outliers algorithm of wireless sensor network.
In wireless sensor network, theoretically the node data in adjacent area has spatial coherence, and same section Data have temporal correlation in point continuous time section.But existing document only has a small number of method for detecting abnormality to consider simultaneously at present Time and spatial coherence, this will necessarily make accuracy in detection reduce or testing cost is made to increase.
