Systems and methods are provided for a distributed mufti-sensor witness integrity sensing platform (WISP) approach which allows for positioning of sensors in an enclosed space. In particular, a WISP platform is divided into two modules, with a base module is connected to multiple edge sensor modules with a wired connection. In general, splitting up the distributed WISP system described herein allows multiple sensors to be placed in an enclosed (and generally inaccessible) location. The sensor data can be transmitted from the multiple edge sensor modules via a connection to the base module. Additionally, the use of the two module system as provided herein allows the sensors to be positioned meters away from the first module.

Distributed witness integrity sensing platform

Aspects of the present disclosure are directed to a measurement module for measurement of a multi-electrode resistive sensing element with improved noise performance and accuracy. In some embodiments, stimulation to the sensing element is provided by a current path that originates from a signal source, through a switch block, through a pair of terminals, and ending at a reference node such as ground. An analog-to-digital converter (ADC) is coupled directly to one or both of the terminals to digitize a voltage. The ADC is coupled to terminals on the sensing element to measure a sensed voltage signal before the sensed signal goes through the switch block. As a result, the measured voltage signal may be free of noise that could be picked up from passing through the switch block, and accuracy of the resistance measurements on the sensing element can be improved.

Wireless integrity sensing acquisition module

Systems and methods are provided for wirelessly communicating with multiple sensors. In particular, a multi-sensor platform is provided that acts as an intermediary node and can communicate with multiple integrity sensors. The integrity sensors are each coupled via a wired connection to the multi-sensor platform, and the multi-sensor platform is powered wirelessly by a radiofrequency transmitter. The radiofrequency transmitter can receive data from multiple sensors via one node, the multi-sensor platform, thus allowing the radiofrequency transmitter to have a static transmission beam.
