Wireless data collector

The wireless data transmission controller is an important component of the wireless monitoring system for rotating machinery status, responsible for communication between the upper computer software and the lower computer, as shown in the following figure:

Vibration monitoring software

RTMSIt is a user-friendly Windows data acquisition and control software that enables real-time display, analysis, and storage of data collected by various sensor nodes. The collected data is stored in the form of a database and can be output to a wide range of third-party software for post-processing. At the same time, real-time monitoring of network communication quality and equipment failure can be implemented, and it has power on self-test and power monitoring functions. Real time alerts for abnormal situations in the network are beneficial for network maintenance and management. The over the air wireless upgrade function of RTMS * software enables convenient internal program upgrades for remote sensor nodes.

Application field

Wireless acceleration sensors combined with RTMS vibration real-time monitoring system provide services for industries such as rotating machinery, construction, bridges, industrial online monitoring, national defense (aviation, aerospace, ships, weapons, nuclear), automobiles, trains, packaging and transportation, and elevators.
