| Within monitoring area, pass the magnanimous low-priced deployment sensor node, will can structure a wireless sensor network. Sensor node in network is able to be in progress with certainly organization way synergetically to the various environment or the information monitoring a marriage partner real time monitor, perception , acquisition and treatment operation. Do not need the infrastructural facilities support, the wireless sensor network simple , resists with regard to having arrangement to destroy nature waiting for merit by force, be able to be completed in very bad or peculiar environment having no way to approach in people monitoring a mission , have the very vast application prospect therefore, attach great importance to having aroused a lot of world country military circle , academic circles and industry circle thereby , has become a forward position hot spot research new and developing field.In the tradition iron-smelting handicraft, adopt the torpedo tank car to load and transport liquid iron. And load liquid iron front , require that the torpedo tank car parks to tapping swing chute lower part to accept iron location, be reported to torpedo tank car serial number. And the allocation realizing the torpedo tank car handles and controls the controller way adopt manpower administration , scene observation in the homeland much, adopt manpower way to fetch the mint-mark serial number on torpedo tank car. Since the jar inner residue being unlike the torpedo tank car there exists difference in amounts, the iron water yield being able to be laden is unlike every tank car , these automatic monitoring device demand to be able to gain the tank car serial number voluntarily , controls a target with the destination ascertaining full jar liquid iron , prevents from overflowing the jar malfunction happening. Because artificial way there exists an uncertainty in operation, the main body of a book adopt a triangulation to come to realize the torpedo tank car automation allocation and the jar number automation identification function with localized algorithm of quality heart appearance anastomosing. Accept iron location accuracy and reliability , make use of radio frequency to mark a technology in order ensuring that the torpedo tank car enters ironworks tapping swing chute lower part's, have interposed Redundancy allocation. At the same time also, the fixer system stating provides the basis from calculation , adjustment to front. The main body of a book main part being completed works as follows:First: have read and have analysed large amount of document data about wireless sensor network , history , network structure , sensor node structure , agreement storehouse structure , characteristic , function valuation standard , key technology and application field having summed up and introducing development of wireless sensor network..Second: have introduced oneself localized to be hit by a node about wireless sensor network, fundamental method and the function valuation indices fixing position including node allocation mechanism , node distance measurement method , the location calculating a node. Have summed up the principle and characteristic being a field's turn to have the typical algorithm and system in recent years.Third: Node allocation algorithm having suggested that one kind of triangulation and quality heart fuses each other, process has carried out detailed expounding on the algorithm fixing position , has used simulated implement of NS2 to have been in progress simulating , have finally to have indicated to the algorithm in the field of average error and, while beacon node number reaches 22, average error cut down greatly.Fourth: has studied hardware design function need , the hardware has chosen type relevance knowledge; Proceed to have been in progress to MSP430 , CC2430 introduce that detailedly; Face to face, the node has designed , redundancy allocation has designed and carried out an at last in application on torpedo tank car to expound. |
