Description

Technical Field

[0001] The present invention relates to the technical field of biosafety laboratories, and in particular to a high-level biosafety laboratory control system. Background Art

[0002] A biological laboratory is a place where biological research is conducted. Unlike general laboratories or cleanroom facilities, it is primarily used for research in biochemistry, biomedicine, animal experiments, microbiology, genetic recombination, and biological products. A biosafety laboratory primarily consists of a contaminated area (i.e., the core operating area), a buffer zone, and a clean area. To operate safely and sustainably, a biosafety laboratory must ensure the safety of personnel, the environment, waste, and samples.

[0003] In high-level biosafety laboratories, biological experiments can expose researchers to sources of infection such as microorganisms and viruses, posing a significant threat to the health and even life of researchers. To address this, researchers are currently required to wear protective clothing. However, ensuring that researchers wear protective clothing and that it complies with standards often relies on their own awareness and operational procedures, without the ability to monitor or proactively alert them. Infections caused by carelessness, such as failure to wear appropriate protective clothing, can often result in serious bodily harm. Furthermore, researchers may forget to remove their protective clothing upon leaving the lab after completing an experiment, potentially contaminating the laboratory. Furthermore, gas leaks within the biosafety laboratory or cross-mixing of gases between different areas within the laboratory can contaminate the laboratory environment. Therefore, ensuring the safety of researchers entering and exiting the biosafety laboratory and preventing the leakage of harmful biological agents from biosafety experiments are crucial.

[0004] An invention patent with application number 202010687179.8, titled "A Method for Controlling a Biosafety Laboratory," has been published. This patent collects body temperature and identity information from individuals seeking to enter the laboratory. The collected identity information and temperature data are then compared with the identity information and normal body temperature range of authorized individuals, allowing authorized individuals with normal body temperatures to enter the laboratory while denying entry to unauthorized individuals and / or individuals with abnormal body temperatures. However, the technical solution of this existing patent design is relatively crude, failing to consider factors such as the wearing of protective clothing, nor the environmental safety issues between various areas of the laboratory. Summary of the Invention

[0005] The present invention aims to solve the problems and deficiencies in the prior art and provides a high-level biosafety laboratory control system.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The present invention provides a high-level biosafety laboratory control system. The biosafety laboratory is divided into a clean area, a buffer area and a contaminated area in sequence. The system is characterized in that the clean area and the outside world, as well as each interval, are each provided with an airtight partition with an airtight door. The system includes a control center, access control terminals located on the inner and outer walls of each airtight partition, and an airtight electronic lock on each airtight door.

[0008] The control center is used to currently receive a command and collect relevant information corresponding to the command, which is the environment-related information corresponding to the command and / or the personnel-related information collected by the access control terminal corresponding to the command, and determine whether the relevant information meets the corresponding preset door opening conditions. If so, the airtight electronic lock corresponding to the access control terminal is controlled to open and the remaining airtight electronic locks are controlled to close; when only the environment-related information does not meet the conditions, a reminder to wait is given, the environment of the relevant area is adjusted so that the environment-related information meets the conditions, the airtight electronic lock corresponding to the access control terminal is controlled to open and the remaining airtight electronic locks are controlled to close; when there is personnel-related information and only the personnel-related information does not meet the conditions, the door will not be opened and a reminder will be given of the reason for not opening.

[0009] Currently, multiple instructions are received, and relevant information corresponding to each instruction is collected. The relevant information is the environment-related information corresponding to the instruction and / or the personnel-related information collected by the access control terminal corresponding to the instruction. It is judged whether the relevant information corresponding to each instruction meets the corresponding preset door opening conditions, and the corresponding airtight electronic lock corresponding to the access control terminal is controlled to open in the order of meeting the conditions, and the remaining airtight electronic locks are controlled to close at the same time; when only the environment-related information corresponding to any instruction does not meet the conditions, a reminder is given to wait, and the environment of the relevant area is adjusted so that the environment-related information meets the conditions, and the airtight electronic lock corresponding to the access control terminal corresponding to the instruction is controlled to open, and the remaining airtight electronic locks are controlled to close at the same time; when any instruction has personnel-related information and only the personnel-related information does not meet the conditions, the door will not be opened and a reminder will be given of the reason for not opening.

[0010] The positive progress effect of the present invention is:

[0011] The present invention takes into account a relatively comprehensive range of influencing factors (body temperature, pressure, and protective measures for putting on and taking off), and can safely control the entry of those to be entered into the clean area, buffer area, and contaminated area; can safely control the exit of those to be exited from the contaminated area, buffer area, and clean area; and can effectively prevent pollution sources in the contaminated area from flowing into the clean area and the external environment, thereby ensuring the life safety of experimenters entering and exiting the biosafety laboratory, the environmental safety of the biosafety laboratory, and preventing the leakage of harmful biological factors in biosafety experiments.
