More Straight Talk About Wireless-Wireless ON/OFF Monitoring and Control Basics for Traffic Applications

摘要

This article is the first in a series of Articles on Wireless ON/OFF Monitoring and Control, also known as Wireless Contact Closure. This first article will go over the basics of this proven and popular technology. The basic idea and benefits of Wireless ON / OFF Monitoring and Control will be explained, along with identifying which Traffic Devices and Traffic Applications "fit" with this technology. The second article in this series will examine how Wireless ON/OFF Monitoring and Control is implemented by examining a single deployment example in detail-important Radio Characteristics, Physical IO Requirements, Data Flows, IO Mapping, Network Topologies/ Radio Operating Modes, System Constraints (debounce times, delays, latency), Installation / Configuration / Diagnostic Features, Product Selection Criteria Product and Vendor Selection Criteria will be identified and discussed. The third article in this series will "look under the hood" and discuss how a Wireless ON/OFF Monitoring and Control Device really works and what design parameters provide the reliable, robust and fast communications required.
