In step S2, the system bug refers to a logical defect or error of the remote recording operating system, and the first remote patch refers to a small program for repairing defects and problems of the operating system of the remote recording master station, wherein the system bug is usually utilized by an illegal person, and attacks or controls the whole system by implanting trojans and viruses, so that whether a system bug exists in the intelligent recorder operating system can be timely judged according to the first remote monitoring information, and thus the first remote patch is obtained and damaged in time, and technical effects of improving software performance and improving use safety of the recorder are achieved.
