Abstract

A handheld wireless transmitter network analysis tool has a transceiver for detecting wireless signals from a transceiver of a smart device used in an automated process control. The tool has a processor with program modules for analyzing the spectrum of received wireless signals and noise. Another memory module includes a device description protocol program for reading tag and primary variable data carried by the wireless signals from smart device. The network tool displays the frequency and spectrum of the wireless signal from smart device, the tag and primary variables for device, the signal to noise ratio and the possible identity of the sources of noise.

Claims

1. A handheld wireless transmitter network analysis tool comprising:

a tool for detecting network communication signals that are transmitted by wireless computer networks in accordance with a first protocol, wherein the tool is configured to analyze the network communication signals and identify one or more features of the wireless computer networks, and wherein simultaneously the tool is further configured to detect wireless signals from one or more smart devices monitoring a process in accordance with one or more second protocols that are different from the first protocol and extract monitored parameters carried by the wireless signals, the tool including;

a receiver that receives a wireless signal originating at a locale proximate to the receiver, the wireless signal being in accordance with one of the one or more second protocols, and the wireless signal carrying a tag specifying a name or a location of a smart device and at least one monitored parameter generated by the smart device monitoring a process of equipment that is separate from the tool, wherein the at least one monitored parameter is a value indicative of at least one of pressure, temperature, flow, or fluid level of the process of the equipment, the receiver further receiving ambient noise signals at the locale of the smart device;

circuitry that converts the received wireless signal and ambient noise signals into digital signals;

a memory for holding digital data and one or more operating and application programs;

a processor that operates said programs to generate data signals representative of the tag, the at least one monitored parameter, and the frequency and magnitude of the received wireless signal; and

a display that shows the frequency and magnitude of the received wireless signal, the tag, and the at least one monitored parameter carried by the received wireless signal.

2. The handheld wireless transmitter network analysis tool of claim 1 wherein the circuitry comprises analog-to-digital conversion circuitry for converting the received wireless signal and the received noise signals into digital data representative of the information carried by the received wireless signal, the frequency and magnitude of the received wireless signal and the frequencies and magnitude of the received noise signals.
