The Design Of Monitoring And Early-warning System For Troop Garrison Based On WSN

Wireless sensor network is deployed by a large number of intensive monitoring of smart sensor nodes in the region consisting of a network application system. For the large number of sensor nodes deployed and randomly put in the only way, the location of sensor nodes can not pre-determined; through the radio channel connection between the nodes at any moment, using multi-hop, peer to peer communication, those nodes self-organize network topology; sensor node has a strong synergy ability to complete the overall task through local data collection, preprocessing, and data exchange between nodes.Information technology is driving a new revolution in military affairs. Information warfare requests combat system, " Understanding, speed, accurately shooting," Who take advantage (to obtain control of information) in the information acquisition, transmission, treatment, who will be able to grasp the initiative in war. For its unique advantages, Wireless Sensor Networks accurately and comprehensively meet the real-time access to military information and other demand in many occasions.ZigBee is a group standard based on the IEEE 802.15.4 wireless approved by the research and development, which relates to networking, security, and application software for technical standards. IEEE handles only low-level MAC layer and physical layer protocols ; ZigBee Alliance to its network layer protocol and API are standardized. The use of ZigBee technology to build the WSN model of early-warning and monitoring for troop garrison, the network is only one network coordinator and have a number of routing nodes.each cluster can be included in a number of terminal equipment which these devices can choose according to their needs RFD, FFD can also be Select . Monitoring and Early-warning System For Troop Garrison ensure accurate and timely warning against illegal intruders, while allowing staff access to a relevant area, more thoroughly improved by sentinel standing guard patrols and the traditional infrared or inductive alarm system not distinguishing the operation of bearer serious deficiencies. Monitoring and Early-warning System For Troop Garrison realizes continuous security precautions monitoring around the clock and for the safety and secrecy of the military garrison is of great significance. The Design of Monitoring and Early-warning System For Troop Garrison Based on WSN has the following seven sub-systems:1) Camp peripheral subsystemsDuring Forcesand field training camp ,the camp is general larger in size. In particular, the division, brigade-level units that are more external perimeter longer. To take the traditional early warning to prevent the establishment of observation towers, set up checkpoints around the camp and infrared sensors that trigger alarms or approach. The first is a waste of strength in this manner, the second is a large gap between the outpost. Distant outpost encounter unexpected situation, information is not timely feedback to their superiors. Especially at night, it is difficult to achieve all-round security. Subsystems in the camp perimeter around the camp set up according to a certain interval of fixed sensor nodes, to achieve full coverage around the camp. Wirelessly connected to the set camp within the Control Center, right outside the camp or camps all personnel officers issued identification card. When the sensor nodes sense that there is identification card out of the camp staff only in the control center background records, but not alarm. If the sensor to a non-insider close to the camp , send fighters to police questioning.2) mobile dispatched subsystemsAt night forces patrolling the traditional post is to patrol inside the camps. To see if it happens, is generally observed with flashlight illumination. In many cases difficult to detect, and the event is particularly dangerous situation is less difficult to dispose of post personnel on patrol. Dereliction of duty and patrol officers will be on the safety of the camp to cause significant risks. Subsystems set up a mobile dispatched to replace the traditional patrol posts, you can set up a mobile patrol car dispatched. mobile sensor nodes are installed in the car. Within the framework of the induction found no identification card for their timely warning to the control center. Control center duty officer sent depending on the circumstances and location of disposal. Officers found identification card is not in the designated areas should also take appropriate measures to deal with.3) The part of the system within the campsID cards are issued to foreign workers. The gate of the army camp and the main trunk road sites and dispatched.If Emplaced detectors at the venue entrance, foreign workers can be effectively managed. If conditions permit, may issue identification cards for all personnel to replace the documents. Can all camp staff (paid foreign workers of foreign personnel identification card, different monitoring points, set different alert levels) can be effective personnel management. Once there do not carry identity cards, or identification card is incorrect then the alarm level. Achieve a 24-hour surveillance throughout the region, effectively improve the management capacity of the camp.4) The meeting place for sub-systemsConference have a higher level of confidentiality is imposed in a war when you. Proceed to a man-made waste of time and because of personnel out of the calculation may result in inaccurate, laid the entrance detector of the participants in the Conference issued identification card, identification card holders only persons allowed to enter and effectively prevent others mixed. And staff participating in the meeting when entering HE Jin to leave, whether the absence can be transmitted through the wireless network control center personnel to facilitate the meeting of the statistics, is also conducive to the record in the future inquiries. 5) ammunition depots, storage subsystemsArms and ammunition is the top in the troop Garrison and priority must be to focus on monitoring. Weapons and ammunition depots are usually someone on duty. Some fixed sensor nodes are installed around the base of weapons and ammunition. Library staff on duty to the arms and ammunition issued a separate confidential level identification card. No identification card or a non-personnel weapons and ammunition depots near the confidentiality of personnel close to the level of identification card, management centers and ammunition depots of arms the same time warning. Need to conduct regular inspections of the on duty personnel to locate identification card and to determine whether the off-site at the management center.6) a road vehicle sub-systems officerOut personnel, vehicles have been issued identity cards. Detectors installed at the main entrance of the camp, which can effectively record personnel, vehicles out of time. It improve the efficiency of the management of personnel and vehicles.It can replace the role of staff to go out cards.7) The manpower resources management sub-systemIn the army camp, the military affairs departments, through the various battalions of the fixed sensor nodes in the control room staff in place the management of the Center for the situation room to collect the information and database comparison. It replaces the inspection of beds and inspection of whistles at night. Battalion and company's main official collection of information can be automatically carried out on the set of persons to carry ID.No artificial name, appearance. In particular, more staff time, improve work efficiency. Levy or casualties in a war, and it reduces in size to recover the identification card and be recorded in the database.Though the rapid development of early-warning and monitoring technology for troop garrison, the transmission distance of wireless terminal node is limited , unable to meet the requirements of early-warning for troop garrison. we establish a network of early-warning and monitoring coordinator with multiple routing nodes in the early-warning and monitoring troop garrison; each routing node is in charge of a monitoring area as part of the terminal nodes with a sub-network and between subnet and subnet which is relatively independent; end-node is installed on the various needs of measurement sensors, responsible for collecting data, through the identifier to determine the membership routing node. Achieving Monitoring and Early-warning for Troop Garrison in the use of the body's thermal infrared sensors, microwave detection technology, combined with wireless sensor network technology.Peripheral camp subsystems consists of four parts, namely: fixed sensor nodes, communication base stations, control centers, Single soldiers ID card. Mobile dispatched subsystem consists of four parts, namely: mobile sensor nodes, communication base stations, control centers, ID card.
