ABSTRACT:Objective For providing clues and directions for solving cases in which explosive devices were triggered with industrial wireless remote control switches. Methods Some basic knowledge about industrial wireless remote control switches and related explosive devices was paved at the beginning, followed with a batch of experimental veriifcation to measure the learning trait, remote control distance and other characteristics of the wireless switches, than a conclusion was achieved. Results This kind of wireless remote control switch can realize one to many, many to one, many to many learning function, the remote control distance does not reach the nominal distance, and height has a great inlfuence on the remote control distance. Conclusion The possibility of spontaneous blast occurrence does exist when this kind of explosive device is involved, and the remote control distance of the wireless remote control switch should be considered in the scene investigation.%目的：针对近年来出现的利用工业无线遥控开关制造爆炸装置的案件，探索案件中爆炸装置出现自爆的可能性、可实现的遥控距离，并初步分析炸后现场装置遗留物，为此类爆炸案件的侦破提供侦查的线索和方向。方法采用实验验证的方法，对不同类型无线开关的学习特征、遥控距离等特性进行测试，探索其工作原理、学习方式、遥控距离。结果这类无线遥控开关可实现一对多、多对一、多对多的学习功能，遥控距离并没有达到标称的距离，且装置所处高度对遥控距离有较大影响。结论此类爆炸装置存在信号误入可能，现场勘查时需考虑无线遥控开关可实现的遥控距离。
