It is a hassle to integrate different sensor network protocols such as zigBee, 6lowpan, rfid, and CAN into one monitoring system. The invention proposes a method to integrate multiple sensor networks with a single standard protocol: Motorola Scalable Controller Area Network (MSCAN). Multiple sensor protocols are converted into MSCAN to facilitate data communication from sensor node to gateway, translator, database and application. The system supports two way communications between application servers and multiple sensor networks.

Description

METHOD OF COMMUNICATING DATA TO MULTIPLE SENSOR NETWORKS
The present invention relates generally to network communications, more particularly to communicating data in multiple sensor networks.
BACKGROUND
Wireless sensor network is a useful network for monitoring data. A plurality of sensor nodes is assigned in multiple places where sensors are located. A plurality of wireless transmitter is integrated into the sensors adapted to a particular input. Sensor nodes in a wireless sensor network can be connected in a network with a gateway.
Currently, various wireless sensor network protocols are being deployed. Some of the common sensor protocols are zigBee, 6lowpan, rfid, wifi, and CAN. It is a hassle to integrate different wireless sensor network due to the difference in protocol deployed. Some system architecture only supports or focuses on targeted sensor network. It is not flexible enough to support multiple sensor networks. It is difficult to integrate multiple wireless sensor networks with a standard protocol.
A prior art describes a method of collecting information by providing information signal consisting of transmitter identification code and an information field, wherein the information signal is received by another nearby transmitter and repeated in the same signal type. The information signal is translated in a gateway into a WAN compatible data transfer protocol. The information signal is then transferred in WAN to a computer. Different sensor networks are being connected by a translator to WAN.
However, the system described is general. There are no specific protocols or architecture mentioned to develop the data communication system.
It is an object of the invention to provide a method to enable multiple sensor networks having different protocols to be networked together with a specific network protocol. It is a waste of resource if certain sensors are restricted to only a certain network having certain protocol. SUMMARY OF INVENTION
The present invention proposes a solution which provides networking with different predefined sensor protocol such as zigBee, 6lowpan, rfid, and CAN. It is able to integrate multiple sensor protocol with a standard protocol. Motorola Scalable Controller Area Network (MSCAN) is chosen as the intermediate standard protocol. A translator is used to translate wireless sensor network protocol into MSCAN and vice versa. The system supports two way communications between application servers and multiple sensor networks.
BRIEF DESCRIPTION OF DRAWINGS
The invention will now be described in greater detail, by way of an example, with reference to the accompanying drawings, in which:
Fig. 1 shows an overview of signal translator and monitoring according to the invention;
Fig. 2 shows a flow chart for communicating data with multiple sensor networks; and Fig. 3 shows a block diagram of data sequence and process DESCRIPTION OF EMBODIMENTS
The data communication system is designed using Motorola Scalable Controller Area Network (MSCAN) binary as an intermediate protocol. An MSCAN raw database is also used as main database design. This protocol and MSCAN raw database will become the link between the different wireless sensor network and its application. The system does not dictate the way data flow within the wireless sensor network itself thus making the wireless sensor network to be configurable to suit its application.
The sensor data from the wireless sensor network will be translated into MSCAN binary protocol at the wireless sensor network gateway. The result will be stored in a raw database in the MSCAN raw database. Any application then can utilize this raw database to suit its application. The system architecture also supports two way communications with any sensor network. The application servers can communicate with multiple sensor network protocols with a single standard protocol.
The MSCAN raw database format uses a simple two column database definition. It consists of data received timestamp and MSCAN binary protocol defined raw data which starts with 7e and ends with 7d.
A signal translator and application monitor is designed to interact between sensor and database, as shown in Fig. 1. With a driver engine, the translator and application monitor receives data sent by gateway (G) from various sensors, such as MIMOS sensor and RFID sensor, in MSCAN protocol and stores the data in a raw database before relaying the sensor data to parser engine. Data is stored in raw database through database interface. Data from sensor network in MSCAN protocol is usually wrapped into a desired communication protocol. Different type of communication medium will require different type of drivers. Examples of communication mediums are serial communication, short message service, and TCP/IP.
In parser engine, the sensor data is parsed in MSCAN protocol into common readable format before being sent to application remote management server. During the parse process, different type of formula is retrieved to parse the data because different sensor network protocols require different formulas. A formula processor is used to modify formula on the fly.
The method of communicating data will now be described, as shown in Fig. 2. A data command is initiated from a remote network management system. The command data is received by parser engine. Parser engine converts the data command into MSCAN protocol. Then, the transmission driver wraps the data command with communication protocol of desired communication medium to be used, such as serial communication, short message service, and TCP/IP. The command is sent to gateway through desired communication medium. The gateway receives the command and checks if it is a broadcast or individual command and converts the command into sensor predefined network such as zigBee, 6lowpan, rfid, and CAN. The router node enhances the communication distance by forwarding the command to another router or at last, the respective node. If there is no communication medium used, the command data does not need to be wrapped and unwrapped with communication protocol.
For actuator node, the node responds to the command and trigger external devices. The actuator node reads the feedback from devices and wraps it to sensor network defined protocol.
For sensor node, the node responds to the command by reading or sampling sensor data. The sensor node collects the data and wraps it in sensor network defined protocol.
The router node enhanced the communication distance by forwarding the sensor data response to another router or at last to gateway. Sensor node collects data from sensor and wraps it to sensor network defined protocol such as zigBee, 6lowpan, rfid, and CAN. When the gateway receives the sensor response, it converts the sensor network protocol to MSCAN protocol and forward to remote network management system through desired communication medium by wrapping the sensor data with communication protocol. Transmission driver unwrap the data from gateway and store the sensor data in raw database server. The parser engine translates the MSCAN protocol to common human readable format and vice versa. Finally, the remote network management system application displays the data and process the command.
Data can be transmitted from application server to sensor network. Application server can issue command and data confined in MSCAN protocol to be passed to transmitter. The transmitter will relay the command to driver and send to sensor network.
A data sequence diagram, as shown in Fig. 3, shows the use of MSCAN protocol. Sensor data is sent from sensor or actuator node. The data is formatted into defined sensor network protocol such as zigBee, 6lowpan, rfid, and CAN. The sensor gateway will convert this data into MSCAN protocol and wrap it into desired communication medium, such as serial communication, short message services or TCP/IP. At the transmission driver, the driver will unwrap the data and store it into raw database in MSCAN protocol. After that, the parser engine can translate the data from MSCAN protocol format into human readable format, before passing it to application server (PAMS). Command data from application server to sensor also goes through a similar, process, said command to be executed at the sensor or actuator.
Accordingly, the invention disclosed a method for communicating data to multiple sensor networks. It is the combination of the above features and its technical advantages give rise to the uniqueness of such invention. Although the descriptions above contain much specificity, these should not be construed as limiting the scope of the embodiment but as merely providing illustrations of some of the presently preferred embodiments.
