Abstract: A personal alarm system includes a monitoring base station and one or more remote sensing units in two-way radio communication. An electronic handshake between the base station and each remote unit is used to assure system reliability. The remote units transmit at selectable power levels. In the absence of an emergency, a remote unit transmits at a power-conserving low power level. Received field strength is measured to determine whether a remote unit has moved beyond a predetermined distance from the base station. If the distance is exceeded, the remote unit transmits at a higher power level. The remote unit includes sensors for common hazards including water emersion, smoke, excessive heat, excessive carbon monoxide concentration, and electrical shock. The base station periodically polls the remote units and displays the status of the environmental sensors. The system is useful in child monitoring, for use with invalids and with employees involved in activities which expose them to environmental risk. Alternative embodiments include a panic button on the remote unit for summoning help, and an audible beacon on the remote unit which can be activated from the base station and useful for locating strayed children. In another embodiment, the remote unit includes a Global Positioning System receiver providing location information for display by the base station.

Abstract translation: 个人报警系统包括监视基站和双向无线电通信中的一个或多个遥感单元。 使用基站和每个远程单元之间的电子握手来确保系统的可靠性。 远程单元以可选择的功率级发送。 在没有紧急情况的情况下，远程单元以节能低功率发射。 测量接收的场强以确定远程单元是否已经移动超出距离基站的预定距离。 如果超出该距离，则远程单元以较高的功率级发射。 远程单元包括用于常见危害的传感器，包括水浸，烟雾，过热，过量的一氧化碳浓度和电击。 基站周期性地轮询远程单元并显示环境传感器的状态。 该系统对儿童监测有用，用于残疾人和参与活动的员工，使他们面临环境风险。 替代实施例包括远程单元上的紧急按钮，用于召唤帮助，以及远程单元上的可听信标，其可以从基站激活并且有助于定位迷路儿童。 在另一个实施例中，远程单元包括提供用于由基站显示的位置信息的全球定位系统接收器。
