For loss and theft in the transport of radioactive materials by a single vehicle, this article summarizes the characteristics of “illegal movement” and establishes a security system that senses its inter-relationship and responds though the group network relationship. The security system reminds the vehicle crew through on-site response and linkage response. A failure detection method for on-site response is proposed, that is, the push model is used first, and when the measurement results are suspected, the pull model is used to further confirm the failure. The failure detection for linkage response adopts the push model. According to the different security requirements of the basic and enhanced transportation, the principle of setting the timeout threshold in the failure detection algorithm is proposed. In the enhanced type, the value is smaller, otherwise the value is larger. A specific timeout threshold quantification scheme is proposed. Experiments show that the method proposed in this article is effective.

基于群体关系的防丢失防盗单车运输安全系统

对于单个车辆运输放射性物质的损失和盗窃，本文总结了“非法移动”的特征，并建立了一种感知其相互关系并通过群体网络关系做出响应的安全系统。安全系统通过现场响应和联动响应提醒车辆乘员。提出了一种现场响应的故障检测方法，即首先采用推模型，当怀疑测量结果时，采用拉模型进一步确定故障。联动响应的故障检测采用推模型。针对基本运输和增强运输的不同安全要求，提出了故障检测算法中设置超时阈值的原则。在增强型中，该值较小，否则，该值较大。提出了一种具体的超时阈值量化方案。实验表明本文提出的方法是有效的。
