摘　　要：为了解决心理学研究中利用实验程序同时给不同接口的实验设备发送指令的问题,设计了一种基于USB与无线传输的心理学实验设备多端口同步触发装置。对当前心理学实验设备同步触发装置的研发现状进行分析,该装置可将433 MHz无线射频信号与USB信号转化为串口或并口信号,并可实现多路串口或并口信号的同步复制输出功能;最后,对心理学实验设备同步触发装置进行了仿真测试。经过测试,该设备数据传输稳定可靠,延迟较低,可满足进行多模态同步实验的要求,具有很高的实际应用价值。In order to simultaneously send instructions to experimental equipment with different interfaces by experimental program in psychological research,a multi-port synchronous trigger device for psychological experimental devices based on USB and wireless transmission is designed.Firstly,the current research and development status of synchronous trigger device for psychological experimental equipment is analyzed.Then the device can convert 433 MHz radio frequency signal and USB signal into serial or parallel port signal,and realize the synchronous replication and output function of multi-serial port or parallel port signal.Finally,the synchronous trigger device for psychological experimental equipment is subject to simulation test.The test results verify that the data transmission of the device is stable and reliable with low delay,and the device can meet the requirements of multi-mode synchronous experiment,which are of very high practical value.
