ADAPTIVE HYBRID WIRELESS AND WIRED PROCESS CONTROL SYSTEM
First Claim
1. A process control and/or automation network for a commercial or industrial processing facility, the network comprising:
- a distributed control system in a central control room within the facility;
a first tier comprising a plurality of wireless end devices receiving instructions from and/or providing data to the distributed control system, the instructions and/or data in the form of packets, each wireless end device being associated with one or more meters, remote terminal units, diagnostic devices, pumps, valves, sensors, or tank level measuring devices;
a second tier comprising a plurality of wireless routers each including a memory that stores a routing table and a processor that routes packets; and
a third tier comprising a master wireless gateway device operably connected to receive packets from and transmit packets to the distributed control system;
wherein the processor of each of the plurality of wireless routers routes packets across the three tiers between the plurality of end devices and the wireless gateway devices based on the stored routing table.

Abstract
A hybrid wired and wireless architecture for a process control system is disclosed that includes hierarchical adaptability and optimization capabilities. The system is arranged in three tiers, the first including a number of wireless end devices exchanging packets of data and/or instructions with the distributed control system, where each wireless end device is associated with one or more meters, remote terminal units, diagnostic devices, pumps, valves, sensors, or tank level measuring devices. The second tier includes a plurality of wireless routers, each including a memory that stores a routing table and a processor that routes packets. The third tier includes a master wireless gateway device operably connected to receive packets from and transmit packets to the distributed control system. The processor of each of the wireless routers routes packets across the tiers between the end devices and the wireless gateway devices based on the stored routing table.
