As a scientific research base , the laboratory stores a lot of valuable data and dangerous goods , so it is necessary to carry out safety monitoring. In this context , a laboratory infrared monitoring system based on conditionally generated countermeasures network is designed. The system framework is designed with the help of B/S three-layer ar- chitecture , which is divided into acquisition layer , network layer and application layer. MySQL is used as the support to design the database. With STC89C52 single chip microcomputer as the core , it controls the peripheral hardware and builds the system hardware. Based on ZigBee technology , the wireless transmission network of the system is established for remote transmission. The function unit of the monitoring system is designed. The infrared image of the laboratory is collected by the acquisition unit , and the pretreatment unit is used to carry out noise removal , brightness adjustment , and image segmentation pretreatment for the infrared image of the laboratory. The anomaly recognition unit is designed based on the condition generation countermeasure network ( cGAN) to determine whether there is any anomaly in the monitoring image and give early warning based on it. The results show that the monitoring results of the system are con-
