Remote confinement system

摘要

A remote confinement system provides a plurality of different unsupervised tests to determine the presence, identity or conduct of the prisoner. The tests preferably include an RF test performed continuously with an RF transmitter attached to the prisoner and a receiver at the remote location, a schedulable voice test performed to identify a person as the specified prisoner, and a breath alcohol test to determine the prisoner's sobriety. The tests are performed with equipment at the remote location in accordance with test selections and schedules selected in a prior automated communication with a central office computer. Events which include test results are communicated to the central office upon a selectively established communications link to the central office, in reply to which communication information selecting subsequent tests procedures or scheduling is communicated from the host to and stored at the remote location. The information communicated from the host includes an identification code for the transmitter attached to the specified prisoner. The RF test generates a message for transmission to the central unit when the prisoner enters or leaves the remote location, but sounds a warning if the signal is lost and delays transmission of the message to allow the prisoner to return following his departure. This application is a continuation-in-part of U.S. patent application Ser. No. 041,698, filed Apr. 21, 1987, and now U.S. Pat. No. 4,843,377, and entitled "Remoted Confinement System" which is hereby expressly incorporated in its entirety herein by reference.
