Portable and rugged power monitoring and analysis of on-Soldier equipment
The eSoldier Power Monitoring System, developed in cooperation of the US ARMY DEVCOM Soldier Center, is a compact, rugged acquisition logging and analysis system for evaluating the power consumption or power generation of Soldier-borne equipment in situ, during field exercises or other real-time events. The system is designed to facilitate easy, unobtrusive sensor data capture through its lightweight compact design and integration of wireless and wired sensor modules.
The system consists of a core portable data acquisition unit (PDAU), which acquires measurement data from a variety of wired and wireless sensor modules. Sensor modules are available to measure voltage, current, temperature, acceleration, and digital inputs. In addition, a GPS antenna can be connected directly to the PDAU for logging location data.
The PDAU can operate either in a standalone mode or in a real-time cabled mode. Easy-to-use software provides an intuitive user interface to configure the system, download and interactively playback all logged data, as well as to display real-time measurement data when operating in cabled mode.
- Compact, rugged (IP67) system for on-Soldier logging of power data
- Wireless and wired sensor modules for acquisition of power, temperature, acceleration, and digital data
(customizable for additional sensor types – contact Bloomy for more information) - Acquire continuous data at up to 1 kS/s and transient data at 100 kS/s
- Data acquisition software simplifies system setup and provides intuitive visualization of acquired data
e-Soldier is the only power monitoring system designed to unobtrusively and accurately capture real energy usage of Soldier-borne devices and equipment during simulation and field exercises. The miniature e-Soldier system is rugged, lightweight, and utilizes distributed wired and wireless sensor nodes to capture critical electrical power and sensor data from multiple devices worn and carried by a Soldier. Easy-to-use software provides intuitive interfaces to collect, manage, and visualize the acquired data.
