  3. 3. About company The development team of wireless network engineering was formed in May 2010 at the ILIT RAS. Intellectual Technology Labs "LINTECH" was established in March 2013. The company is engaged in the development and implementation of wireless sensor networks and monitoring systems in various application areas. "LINTECH" is a resident of Skolkovo Innovation Fund since May 2013.
  4. 4. The company's activities The main business is the development and implementation of hardware and software of wireless sensor networks (WSN), which allows economically to solve a wide range of engineering, industrial and domestic problems of modern life. The company's mission “Introduction of “smart dust” will make the world a safer, more secure and more environmentally.”
  5. 5. Wireless sensor networks This device is capable to organize itself in ad-hoc network on given architecture and to execute distributed accounting, GRID computing
  6. 6. The main function of wireless sensor network (WSN) The main function of WSN is the solution of problems of collecting, information processing and transmission with high demands for autonomy, reliability, scalability, and distributed network.
  7. 7. Advantages of systems based on sensor networks - promptness and economy of deployment; - there is no need in service; - extended autonomous operation; - advanced fault tolerance and reliability under severe operating conditions; - wide field of application.
  8. 8. The technology of sensor networks. Composition of WSN. DSN consists of hardware and software. Zigbee IEEE 802.15.4 standard. WSN are protected by original algorithms and software.
  9. 9. The hardware of WSN WSN hardware are: • endpoints (nodes of networks) for collection parameters; • routers; • coordinator of the Network; • gateway that has a radio transceiver and united in a networked. Hardware base is commercially available.
  10. 10. The structure node of WSN One node consists of: - microchip; - RF-transmitter; - sensor; - battery.
  11. 11. The software part of WSN The software, based on the original algorithms, which are protected by copyright: - to control, data collection and transmission; - to visualize the results. OS: TinyOS, Linux, Win. Programming language: C, Java. Сompiler gcc
  12. 12. Zigbee IEEE 802.15.4 standard Standard IEEE 802.15.4, also known as ZigBee, is a low-speed connection standard intended for low-power, short-range communication between wireless devices. In addition, radioequipment ZigBee must have an extremely low power consumption, and must work for years without replacement of power sources.
  13. 13. Characteristics of the sensor The network topology The options: 1) Star, 2) Tree, 3) Mixed, multi-cell Mode of operation of the nodes The options: 1) Continuous, 2) sleep on a schedule 3) Sleep on event Access to the environment Via wireless channel to a frequency of 2.4 GHz Noise immunity 11 subchannels. One of the 64 PAN ID networks may be selected in each channel. Energy consumption from the batteries: Voltage 2.8 — 3.4 V The current in the receiving mode in 50mA 3.3V The current in the transmission mode 45-270mA 3.3V The current in sleep mode <10 uA Transmission range up to 100 m clear line of sight using chip Xbee2sm, up to 1000 m with chip Xbee2PRO Frequency band 2.4 GHz
  14. 14. Fields of application: 1. Housing and communal services. 2. Radiation monitoring. 3. Industrial monitoring. 4. Transport. 5. Constructing. 6. Medicine. 7. Safety systems. 8. Education.
  15. 15. The field of application. Housing and communal services. - elevator monitoring; - data collection from metering devices; - control of ventilation of premises. Sensors in the elevator
  16. 16. Advantages of using sensor networks in the field of housing and communal services - getting the current data from metering devices; - easy of tracking and payment of public utilities; - fault tolerance system; - reduce the cost of rebuilding infrastructure in an emergency.
  17. 17. Problems of the modern industrial and environmental monitoring (if using wired connection) Installation of wires requires the development of the project, a lot of time and financial costs.
  18. 18. In the event of breakage of wires can be difficult to diagnose break points and to make repair works. Sometimes, the cost of repair exceeds the value of laying new cables!
  19. 19. The advantages of using sensor networks for systems of monitoring     The possibility of the placement in inaccessible locations; Quick deployment and system maintenance; The reliability of the whole network - in case of failure to 40% of nodes of the network, the network performs its functions; Can be added or removed any number of devices from the network;  High level of penetration through obstacles (walls, ceilings) and resistance to electromagnetic interference (unlike wi-fi);  Long operating time without battery replacement due to budget conscious microchips and algorithms developed in the framework of the project;   Reducing the cost of maintenance building of systems; Reducing the cost of data collection of secondary information (development of service).
