However, because it is a recent protocol, there are still research to be developed, being one of the areas related to the inspection and monitoring of WirelessHART networks in real environments. This paper presents a comparative analysis of tools for analyzing WirelessHART networks currently available in the literature and proposes a new tool, which has the advantages of mobility and inspection on all 15 channels of the WirelessHART network using only one radio, which is set dynamically during network operation. It is a solution of hardware and software that provides analysis of the logical and physical characteristics of the network, having the capability of measuring the energy level in channels concurrently with logical aspects of the links. Keywords WirelessHART, Analysis of wireless networks, IEEE 802.15.4, Systems automation. Resumo O protocolo WirelessHART tem sido cada vez mais aplicado no monitoramento e controle de processos industriais, devido à sua alta confiabilidade e robustez. No entanto, por se tratar de um protocolo recente, ainda há pesquisas a serem desenvolvidas, sendo uma das áreas referente à inspeção e monitoramento de redes WirelessHART em ambientes reais. Este trabalho apresenta uma análise comparativa das ferramentas para análise de redes WirelessHART disponíveis atualmente na literatura e propõe uma nova ferramenta, que apresenta como vantagens a mobilidade e a inspeção em todos os 15 canais da rede WirelessHART utilizando apenas um rádio, que é programado dinamicamente durante o funcionamento da rede. Trata-se de uma solução de hardware e software que proporciona análise lógica e física da rede, possuindo a capacidade de medição do nível de energia nos canais, concomitantemente com aspectos lógicos dos enlaces. Palavras-chave WirelessHART, Análise de redes sem fio, IEEE 802.15.4, Sistemas de automação.
