摘　　要：目的设计一种基于Zigbee技术的心理状态测试仪。方法将脉搏传感器采集到的搏动信号通过模拟电路的预处理,经模数转换后得到数字信号,再将转换后的数字信号通过ZigBee无线通讯节点发送到上位机,进行处理和显示,并由上位机存储数据,便于用户进行心理状态的评估。结果实验表明,此仪器能够对人体的脉搏信号进行实时采集,同时可通过ZigBee无线网络进行实时、安全、可靠的通信,可用于心理状态的测试研究。结论该心理状态测试仪通过运用ZigBee无线通信技术,可以通过便携式无线终端采集到脉搏数据,反映个体在不同情况下的心理状态,使测试系统具有移动性,因此能广泛适用于心理素质评估等领域。Objective To design a psychological state tester based on ZigBee wireless technology. Methods Through analog circuit preprocessing, the heartbeat collected by the pulse sensor will be transformed into digital signal from analog signal, and then can be processed and displayed after transported to the personal computer through the Zigbee wireless communicate units. The data will be retrieval and playback for the measurement of psychology. Results The experiments show that the device is able to acquire the pulse wave of the human body in real-time, at the same time, through the ZigBee wireless network, it can accomplish real-time, secure and reliable communications, and it also can be used in the research of testing the mental state of the individual. Conclusion Through the application of the ZigBee communicate technology; the psychology tester can collect the pulse signal to reflect the individual＇s mental state in different conditions. So it will be applicable to a wide range of psychology measurement and other areas.
