To design a psychological state tester based on ZigBee wireless technology.
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.
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.
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.
设计一种基于ZigBee无线技术的心理状态测试仪。
通过模拟电路预处理，脉搏传感器采集的心跳将从模拟信号转换为数字信号，然后通过Zigbee无线通信单元传输到个人计算机后进行处理和显示。这些数据将被检索和回放以用于心理测量。
实验表明，该装置能够实时获取人体脉搏波，同时通过ZigBee无线网络能够完成实时、安全可靠的通信，还可用于个体心理状态测试研究。
通过应用ZigBee通信技术，心理测试仪可以采集脉搏信号以反映个体在不同状态下的心理状态。因此它将适用于广泛的心理测量及其他领域。
