摘要 - 现今的日常生活中用电安全问题时刻都在敲响着警钟，为了解决传统用电安全的问题，用电安全体验系统在各种仿真器和电器元件的基本工作原理上进行设计。该系统的重点在于体验用电事故并预防此类事件的发生。其主要工作原理是将开关量、传感器和安全设备的状态变化传输到Logo模块判定然后输出。首先其检测设备插头、插座和电路的状态等的样本信息由网线与电线进行传输，然后该系统分析这些信息并通过物理模拟输出模拟出用电事故现象。当用电事故发生时，系统会触发其相对应的模拟事故现象的设备，如突然的闪光，烟雾，爆炸声响等。通过这种方式体验者可以更直观的理解危险用电造成的严重后果，从而达到安全用电的效果。已经证明该系统可以完成体验危险用电的功能。78819

Design of Safe Experience Device for Short Circuit

Abstract：In order to solve the problem of traditional electricity safety, electric safety experience system in a variety of simulators and electrical components of the basic principles of the design。 The focus of the system is to experience the use of electricity accidents and to prevent the occurrence of such incidents。 The main principle is to switch the amount of sensors and safety equipment to the status of changes to the Logo module to determine the output。 First, the sample information of the detection device plug, socket and circuit status is transmitted by the network cable and the electric wire, and then the system analyzes the information and simulates the electric accident phenomenon through the physical analog output[1]。 When a power accident occurs, the system will trigger its corresponding simulation of the accident phenomenon of equipment, such as sudden flash, smoke, explosion and so on。 Through this way experience can be a more intuitive understanding of the serious consequences of dangerous electricity, so as to achieve the effect of safe electricity。 The system has been proven to be able to experience the function of hazardous electricity。
