摘　　要：目的研制一种用于战场伤员搜寻、急救的远程无线生理监护、定位系统--单兵状态监视器系统.方法从心电信号中提取心率,用温度晶体测量体温,采用个人状态监视器全球定位系统技术(global position system,GPS)确定单兵的位置,以扩频通讯芯片组实现生命信息和位置信息的无线扩频传送.结果扩频通讯数据传输可达1000 m明视距离;GPS定位误差小于100m,心率监测在30～250beats/min的范围内误差不超过1 beat,体温监测在25～45℃范围内误差不超过0.1℃.结论实现了1 000 m距离内生命、位置信息融合后的无线扩频传送.Objective To develop a wireless apparatus for remote physiological monitoring and positioning of the personnel which can be utilized in searching and implementing emergency care for the wounded in the battlefield. Methods The heart rate was obtained from electrocardiogram, and body temperature was measured by using a temperature crystal. Positioning of the personnel was realized with the assistance of global positioning system, and wireless transmission of physiological and po-sition data accomplished by way of spread spectrum communication chip set. Results Data transmission by spread spectrum communication covered a distance as far as 1 kilometer, and the error was controlled below 100 m in positioning. In the span of 30 to 250 beats/min, the heart rate error was less than 1 beat/min, and the body temperature error less than 0.1 ℃in the span of 25 to 45 ℃. Conclusions This wireless device meets the demands of spread spectrum transfer of physiological and position data at the distance of 1 kilometer.
