Description
CONFIGURABLE MULTI-PROTOCOL SERIAL-TO-IEEE802.15.4 MESH
NETWORK GATEWAY/ROUTER
FIELD OF THE INVENTION
This invention relates generally to wireless sensor network, more particularly, to an apparatus and a method to configure the apparatus as a gateway and/or a router to provide immediate over-the-air mesh links to replace the wired link between existing controller and remote devices in industrial automation networks.
BACKGROUND OF THE INVENTION
Industrial automation networks consist of controllers, sensors and actuators.
Controllers communicate with remote sensors to gather data regarding such variables as temperature, pressure, vibration, and strain; and controllers act on that data by issuing commands that orchestrate process among such actuators as relay, motors, and valves.
In most cases, the communications among controllers and sensors/actuators are driven by the open serial protocols such as Modbus, Optomux, DNP3, and BACnet MS/TP over serial communication cables such as RS-485.
Wiring in industrial automation networks represents a tremendous cable cost, labour cost, and retrofit cost. Cables themselves can represent nuisances or safety hazards. Cabling runs have severe length limits, leaving networks unable to address very remote sensors and actuators in such environment as large-scale plants.
One simply solution for wiring problem is wireless gateway approach. Those controller and sensors and/or actuators are wirelessly networked through serial to wireless gateways and possible some wireless routers. It is transparency for the existing applications in the controller and the sensors and/or actuators.
Wireless mesh networking technologies based on IEEE802.15.4, such as ZigBee protocol or other Zigbee-like protocol, are very good candidates for the wireless gateway solution of the wired industrial automation network.
SUMMARY OF THE INVENTION
The invention is an apparatus that is made up of: a microprocessor; a serial connector, such as RS485 or RS232, connecting to an industrial automation controller or a sensor or a actuator for standard serial data transmission between them and the apparatus; a RF
chip, such as IEEE802.15.4 radio chip to transmit or receive standard wireless data among apparatus; a LCD to display configuration parameters, such as baud rate, serial protocol, address, channel number, personal area network id, and type of the apparatus etc.; a non-volatile memory to store program and the configuration parameters;
a plurality of push buttons to configure the configuration parameters; a program stored in the memory cause the microprocessor to set up wireless mesh link with other apparatus, to receive serial data through serial connector and forward to the destination apparatus through RF, to receive wireless data from RF designated to it and forward out through the serial connector, or to receive wireless data from RF and route to another apparatus through RF.
In the drawings as hereinafter described, a preferred embodiment is depicted;
however, various other modifications and alternate constructions can be made thereto without departing from the true spirit and scope of the invention.

Referring to the block diagram FIGURE-2, a configurable multi-protocol serial-to-IEEE802.15.4 mesh network gateway router 10 includes a microprocessor 21 in communication with a memory 22 which stores configuration data and program, a serial connector via a serial communication interface 24, a liquid crystal display (LCD) 12, a plurality of configure push buttons 11, and an IEEE802.15.4 RF chip 23. The configurable multi-protocol serial.-to-ieee802.15.4 mesh network gateway router may be suitably powered by an external power supply (not shown) and/or from equipment to which is connected.
Referring to FIGURE-3, there is shown a typical usage of configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway routers in an industrial automation network.
A configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway router configured as master type 34 is connected to a controller 31 via serial link 37. A
configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway router configured as slave type 35 is connected to a sensor 32 via serial link 37. A
configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway router configured as slave type 35 is connected to an actuator 33 via serial link 37. There is only one controller whereas there may be many sensors and actuators. These configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway routers together with some configurable multi-protocol serial-to-ieee802.15.4 mesh network gateway routers configured as router type form a wireless self-healing mesh network 30, which transports the serial protocol data between controller 31 and sensors/actuators 32/33 and which adopts a mesh network protocol based on IEEE802.15.4 such as Zigbee or else.
Referring to FIGURE-4, there is shown how to initiate a configuration procedure. First the menu button is pressed and held, next reset button is pressed and released, later releasing the menu button will lead to the IEEE802.15.4 channel configure mode.
Referring to FIGURE-5, there is shown how to configure the IEEE802.15.4 channel.
The channel numbers assigned by the IEEE802.15.4 standard are between 1 and 26.
Pressing then releasing the change button will increment the channel cyclically among 1, 2 ... and 26. Pressing and releasing the menu button, when the LCD displays the desired channel number, will lead to the IEEE802.15.4 personal area network identifier configure mode.

The PAN ID assigned by the IEEE802.15.4 standard is a number with four hex digits between Ox0000 and OxFFFF. In the beginning of the PAN ID configure procedure, the LCD cursor focuses on the first hex digit.
Pressing then releasing the change button will increment the cursor focused hex digit cyclically among 0, 1... and F. Pressing and releasing the menu button, when the LCD displays the desired hex digit, will cause cursor to focus next hex digit to start the procedure for configuring this hex digit; or lead to the IEEE802.15.4 short address configure mode if the hex digit focused by cursor is the fourth digit.
