The functional modules are positioned at different working levels and cooperatively complete the functions of data acquisition, storage, presentation and the like.

The functional structures of the communication subsystem 1, the acquisition subsystem 2, the processing subsystem 3 and the monitoring subsystem 4 shown in fig. 2 are identical to those of fig. 1, and are not described in detail herein.

In one embodiment, the communication subsystem 1, the acquisition subsystem 2, the processing subsystem 3, the storage subsystem 7, and the encryption subsystem 8 run on an information acquisition management computer.

The alarm subsystem 5 is connected with the monitoring subsystem 4, receives alarm signals transmitted by the monitoring subsystem 4 and is used for informing staff of the source of the alarm signals in an acousto-optic mode. The management subsystem 6 is connected with the monitoring subsystem 4 and is used for managing user data, subsystem parameters and logs.

When the monitoring subsystem 4 receives the alarm signal transmitted by the information acquisition management computer, the alarm subsystem 5 is triggered. When the user needs to check the historical data, the monitoring subsystem 4 reads the data from the security recorder 9 according to the user requirement and displays the data to the user for checking through a human-computer interface.

The storage subsystem 7 is connected with the processing subsystem 3, organizes the storage of management data, and is used for writing the analysis data into the database according to the agreed storage rules. Specifically, the storage subsystem 7 organizes the storage of management data, the data that the system needs to store are the switching value, the monitoring value, the alarm signal, the audio and video data, the log, etc. that are collected, all data are written into the database by the storage subsystem 7 according to the agreed storage rules, and are transmitted to the encryption subsystem 8 at the same time.

Specifically, the security recorder 9 is a separate subsystem, and communicates with the information acquisition management computer through the TCP/IP protocol, and various encrypted monitoring data received by the information acquisition management computer are acquired in real time and written into the security recorder 9 periodically. The security recorder 9 adopts a cyclic writing mode, so that the latest data can be effectively protected, and the timeliness of the data is ensured.

Further, in order to store data with a sufficiently long period (24 hours or more), the security recorder 9 is used, and has extremely high reliability and fast reading and writing capability. The device takes Linux as an operating system, and maps the device into a certain hard disk of an information acquisition processor through a mapping program based on TCP/IP, so that the system can manage the security recorder 9 in a mode of managing a local hard disk. After the system collects the data, the collected data is synchronously written into the security recorder 9. The safety recorder 9 can resist the erosion of various severe natural disasters such as high temperature, high pressure, corrosion, thunderstorm and the like, and protect the safety of data under extreme conditions. In this way, in case of a major accident, the state and the cause of the accident can be traced back by reading and analyzing the data in the safety recorder 9.

The data is transmitted to the processing subsystem 3 for centralized processing after being collected, the data is analyzed and then is transmitted to the monitoring subsystem 4 for display, and if the data triggers an alarm signal, the alarm subsystem 5 alarms through an acousto-optic signal to remind a worker or a safety manager to carry out necessary processing. The parsed data is simultaneously transferred to the storage subsystem 7 for writing into the database for long-term storage. While the storage subsystem 7 periodically writes data to the security recorder 9.
