Monitoring system including an electronic sensor platform and an interrogation transceiver
First Claim
1. A monitoring system comprising:
- at least one electronic sensor platform, comprising;
a plurality of sensors comprising at least a fiber optic seal sensor, a case tamper sensor, and a sensor to detect the condition of sensitive material proximate to said sensor platform;
an RF transceiver for transmitting data from the plurality of sensors;
a message buffer, in electronic communication with said plurality of sensors and said RF transceiver, wherein said message buffer periodically stores status data generated by each of said plurality of sensors;
a source of electrical power operatively connected to each of said plurality of sensors, to said message buffer, and to said RF transceiver; and
an interrogator transceiver constructed to communicate with any of said RF transceivers over an RF link; and
a host computer operatively connected to send signals to and receive signals from said interrogator transceiver.

Abstract
A wireless monitoring system suitable for a wide range of remote data collection applications. The system includes at least one Electronic Sensor Platform (ESP), an Interrogator Transceiver (IT) and a general purpose host computer. The ESP functions as a remote data collector from a number of digital and analog sensors located therein. The host computer provides for data logging, testing, demonstration, installation checkout, and troubleshooting of the system. The IT transmits signals from one or more ESP'"'"'s to the host computer to the ESP'"'"'s. The IT host computer may be powered by a common power supply, and each ESP is individually powered by a battery. This monitoring system has an extremely low power consumption which allows remote operation of the ESP for long periods; provides authenticated message traffic over a wireless network; utilizes state-of-health and tamper sensors to ensure that the ESP is secure and undamaged; has robust housing of the ESP suitable for use in radiation environments; and is low in cost. With one base station (host computer and interrogator transceiver), multiple ESP'"'"'s may be controlled at a single monitoring site.
