Abstract

A Wireless Sensor Network system 100 including sensors with transceivers 101, 102 connected to a Mobile Base Station 110 connected to a Server on the Internet that processes the information and configures it for display on web pages, MMS, SMS, J2ME and other mobile applications 121, 122, 123. The system is designed to allow the end user(s) to receive real-time data, or historical data, at any time and also receive alerts of changes in information while on the move. The users can update/modify parameters of the sensor network, in real-time, via any of the aforementioned interfaces 121, 122, 123. Data gathered will be stored in databases for trend analysis and modelling.

Description

1 2408892 The invention relates to a wireless sensor network and the
subsequent processing and delivery of the information gathered.
Sensors are common devices used in everyday life to monitor everything from heart rate to water pressure. Most present day sensor systems are wire based. They send raw data, via wires, to a computing system for storage and possibly some processing. This method has two main drawbacks, the time and cost to lay the cables and that a contralised data acquisition system has no real-time value or intelligence to control the entire system.
Wired sensor networks have the disadvantage of being restrictive or impossible to install, particularly with moving objects. They can be safety hazards, for example in construction site monitoring. Existing systems using a data logger must be accessed locally to retrieve the saved data. It then requires separate processing to change the raw data into something meaningful, which is an inefficient use of man-hours.
An objective of this invention is to provide monitoring and control that is not intrusive and allows freedom of movement of the object being monitored. The information gathered is stored for analysis and control purposes. Historical data can be sent to users if requested while realtime data is streamed to users via a variety of methods outlined below.
Accordingly, this invention provides a sensor network connecting wirelessly to a portable wireless base station connected to a web server which in turn displays the data via WWW (World-Wide-Web), J2ME_ (Java 2 Micro Edition), WAP (Wireless Application Protocol), SMS (Smart Message Service), MMS (Multimedia Message Service), 2.5G (extended 2nd Generation mobile network) or 3G (3rd Generation mobile network) applications. This invention can display real-time information and allows the end-user to control and update the system via the same interfaces.
The preferred choice of sensor are digital MEMS (Micro Electro Mechanical System) based.
Current MEMS can be used to accurately measure acceleration, tilt, pressure, flow, temperature, chemical agents, gases and many more. Existing analogue sensors can also be used via an ADC (Analogue to Digital Converter).
The preferred choice of wireless communication to and from the sensor nodes is digital radio.
Specifically Bluetooth_, FM and ZigBee_. These radio technologies would allow for high transmission distances and longer battery life. Solar cells will be used to increase battery longevity. Relay nodes will be used to increase transmission distances further still.
The preferred choice of communication to and from the Mobile Base Station will be cellular radio network through IP (Internet Protocol). Specifically UMTS (Universal Mobile Telecommunications System), EDGE (Enhanced Data rate for Global Evolution), GPRS (General Packet Radio Service) or Satellite. This is suited to remote locations such as bridges and dams. A wired alternative would be LAN (Local Area Network); this would be suited to office buildings that have local Internet access. Additionally to allow the Base Station more freedom in an office scenario IEEE 802.11a/b/g, also known as WLAN (Wireless LAN), would be used. The base station would be capable to be run from mains supply or rechargeable battery pack to offer maximum mobility.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows an overview of the invention, Wireless Sensor Network system.
Figure 2 shows the use of the system in monitoring of a suspension bridge.
Figure 3 shows the system monitoring a water dam.
Figure 4 shows the system monitoring a person and their home.
As shown in Figure 1, the invention 100 comprises of four main units: Wireless sensor nodes 101,102 Mobile Base Station 110 Server system 115 User display 121,122,123 The wireless sensor nodes 101, 102 contain a digital MEMS sensor(s) 104 and/or analogue sensor(s) and ADC 105. All nodes will have a wireless transceiver with antenna 106, microcontroller(s) (also referred to as IlCs) and memory 107, a re-useable battery 108 and solar cells 109. The purpose of the micro-controller(s) and memory 107 are to interface between the transceiver, sensor and power system. A secondary function is to increase power efficiency via preprocessing and buffering of data before transmission. The radio system employed by the transceiver 106 will depend on transmission distance, bandwidth, power emissions etc. The sensor nodes 101, 102 will connect to the Mobile Base Station 110 directly via their transceivers or through a relay node(s) 103. Information or data can be passed in both directions. The Mobile Base Station 110 will contain a transceiver(s) 111 to connect to the nodes, a CPU (Central Processing Unit) and memory 112, power supply and regulation 113 and a connection 114 to the Server system 115. The CPU and memory 112 will contain the connection details and data sent from the sensor nodes 101, 102 as well as how to send data back to the Server system 115. The protocol system used to connect to the Server system 115 is IP based and can be achieved via cellular modem, satellite, or wired/wireless network as shown in Figure 1. The Mobile Base Station 110 can be powered via mains supply, where suitable or battery supplied 113.
The function of the Server system 115 is to process and analyse all the data sent to it from the base station(s) 110. It will store all data in individual project databases 116. It will carry out data analysis 117 for modelling and trend recognition. It will format data and deliver it as requested or scheduled by the end-user.
The delivery methods used will allow for users to be able to view realtime andlor historical data from anywhere with an Intcrnet connection 121 or mobile network service 122, 123. It will allow the user(s) to control or update the system via any interface 121, 122, 123.
Referring to Figure 2, an application utilising the invention 100 is illustrated. A suspension bridge 200 is to be monitored. Sensor nodes 101, 102 are installed in key locations on the bridge structure, for example the base, top, cables and joins between the cabling and structure 201-206. They connect to the local Mobile Base Station 110 directly and via relay nodes 103.
The sensors collect data on 3-D tilt, temperature, the stress and strain of the steel cables and concrete structure etc. The chemical changes of the structure caused by the weather can be monitored along with mechanical parts used in counterweights.
The number of sensors used will be specific to each individual structure and the base station will be able to manage many nodes by forming ad-hoc networks, using round-robin scheduling and store and forward techniques. The combination of data from all sensors allows for complete monitoring of the bridge. The Mobile Base Station 110 will carry out error checking and data processing to ensure data integrity. In addition to this the nodes 101, 102 will carry out pre-processing of the data to catch critical readings. For example if the stress on one or more cable(s) 206 were to reach its limit the sensor node 101, 102, will immediately contact the Mobile Base Station 110 and issue a warning message. This will be passed to appropriate user(s) via SMS, MMS 119, voice call, video call 122, cmail, HTML (Hyper-Text Mark-up Language) and XML (extensible Mark-up Language) 120, 121, 123.
Data will be time/date stamped and stored in the database 116 and analysed for trends in the Server system 115. Users may view data via web 121 and mobile devices 122, 123. The user will have to go through an authentication centre 118 to view/modify system settings, with all communications being encrypted. Users will be allowed to set their own threshold values for sensors and methods for receiving them. Users will be set privileges and rights 118 so that not all users on the system can change critical settings.
Referring now to Figure 3, the invention 100 is applied to a water dam 300. Sensor nodes 101, 102 are strategically placed on the dam, for example the base, the top 301-305, to monitor fractures, pressure and acceleration. Additional nodes 101, 102 are placed on the ground to measure soil movement and vibrations 306, 307.
Referring now to Figure 4, the invention 100 is applied to house/personal health monitoring 400. The home environment can be monitored and controlled by creating sensor nodes 101, 102 in pressure mats 401, windows 402 and light fixtures 403. It can be used to monitor people in care homes, by creating movement belts 404. For example an elderly person can wear a belt that has a sensor node 404 that measures vibrations and acceleration. Data is being sent to the Mobile Base Station 110. This in turn stores the information and at regular intervals sends it to the Sever for processing and storage. A user i.e. doctor can connect through the Server and receive real-time data using web 121 and/or mobile phone 122, 123.
If the elderly person were to fall or not move for a long period of time the sensor node 404 would recognise this. It would send a signal to the Mobile Base Station 110, which would start the procedure to send an alert/warning message via SMS, MMS and/or voice call 122, 123, to the appropriate personnel i.e. the doctor, nurse to inform them of the situation.
