[0021] Embodiment 1

[0022] The embodiment of the present application provides a personnel access management method for a biosafety laboratory based on a blockchain, comprising the following steps:

[0023] Firstly, a circulating blockchain (composed of M temporary storage blocks) and a storage blockchain (composed of N storage blocks) are constructed in advance, the circulating blockchain includes two smart contracts, the first smart contract includes one-in-one-out instructions for the same area with the same time stamp sequentially stored in the same temporary storage block, multiple instructions for different areas with the same time stamp sequentially stored in different temporary storage blocks according to instruction priority, and instructions with different time stamps sequentially stored in different temporary storage blocks according to the time sequence of the time stamps, and the second smart contract includes the door opening rules corresponding to each access instruction. Wherein, the instruction priority is A3 出 instruction>A2 出 instruction>A1 出 instruction>A3 进 instruction>A2 进 instruction>A1 进 instruction, M and N are positive integers, and M

[0024] In this step, at the same time, one-in-one-out instructions for the same area are stored in the same temporary storage block, such as receiving A1 进 instruction and A1 出 instruction at the same time, then A1进 instruction and A1 出 instruction is temporarily stored in the same temporary storage block, and A2 is received at the same time 进 instruction and A2 出 instruction, and A2 进 instruction and A2 出 instruction is temporarily stored in the same temporary storage block, and A3 is received at the same time 进 instruction and A3 出 instruction, and A2 进 instruction and A2 出 instruction is temporarily stored in the same temporary storage block.

[0025] In this step, at the same time, a plurality of instructions for different areas are sequentially stored in different temporary storage blocks according to instruction priority, such as A1 进 instruction and A2 出 instruction, A2 is first stored 出 instruction is temporarily stored in one temporary storage block, and A1 进 instruction is temporarily stored in the next temporary storage block.

[0026] In this step, instructions received at different times are sequentially stored in different temporary storage blocks according to the time sequence of the instruction timestamp.

[0027] In this step, in the second smart contract, A1 进 The door opening rule corresponding to the instruction is: the body temperature of the person to be admitted is within the preset body temperature range, the identity of the person to be admitted is within the preset authorized range, and P 洁 <P 外 .

[0028] A2 进 The door opening rule corresponding to the instruction is: P 缓 <P 洁 .

[0029] A3 进 The door opening rule corresponding to the instruction is: the person to be admitted wears protective measures matched with the high-level biosafety laboratory, and P 污 <P 缓 .

[0030] A1 出 The door opening rule corresponding to the instruction is: the body temperature of the person to be admitted is within the preset body temperature range, and P 洁 <P 外 .

[0031] A2 出 The door opening rule corresponding to the instruction is: the person to be admitted has completely removed the protective measures, and P 缓 <P

[0032] A3出 The door opening rule corresponding to the instruction is P 污 <P 缓 .

[0033] Second step, receiving the instruction, and storing the instruction, its timestamp and the door opening rule of the instruction based on the second smart contract into the corresponding temporary storage block according to the first smart contract, and collecting the relevant information corresponding to the instruction into the temporary storage block of the instruction; the relevant information corresponding to the instruction includes the pressure related information corresponding to the instruction and / or the to-be-entered / exited personnel related information corresponding to the instruction.

[0034] Continuously circulating the circulating blockchain, judging whether there is an instruction in the current temporary storage block, if yes, judging whether the collected relevant information all meet the corresponding door opening rule, if yes, controlling the door corresponding to the instruction to open and controlling the remaining doors to close, moving all data in the current temporary storage block to the first blank storage block in the storage blockchain in order, judging the next temporary storage block, and the current temporary storage block becomes a blank temporary storage block; when only the pressure related information does not meet the corresponding door opening rule, reminding the to-be-entered / exited personnel to wait, adjusting the pressure of the relevant area so that the pressure related information meets the corresponding door opening rule, controlling the door corresponding to the instruction to open and controlling the remaining doors to close, moving all data in the current temporary storage block to the first blank storage block in the storage blockchain in order, judging the next temporary storage block, and the current temporary storage block becomes a blank temporary storage block; when there is to-be-entered / exited personnel related information and the to-be-entered / exited personnel related information does not meet the corresponding door opening rule, reminding the reason why the door does not open, moving all data in the current temporary storage block to the first blank storage block in the storage blockchain in order, judging the next temporary storage block, and the current temporary storage block becomes a blank temporary storage block; if there is no instruction in the current temporary storage block, judging the next temporary storage block.

[0035] A further optimized technical solution involves determining whether there is an instruction in the current temporary storage block. If so, and there is only one instruction, it checks whether all the collected information related to that instruction meets the corresponding door opening rules. If so, it controls the door corresponding to that instruction to open and simultaneously controls the other doors to close, transferring all data in the current temporary storage block to the first blank storage block in the storage blockchain in sequence. Then, it checks the next temporary storage block, making the current temporary storage block a blank block. If only the pressure information in the instruction's information does not meet the corresponding door opening rules, it alerts personnel waiting to enter / exit to wait, adjusts the pressure in the relevant area to make the pressure information meet the corresponding door opening rules, controls the door corresponding to that instruction to open and simultaneously controls the other doors to close, transferring all data in the current temporary storage block... The data is transferred to the first blank storage block in the storage blockchain in sequence. The next temporary storage block is then determined, and the current temporary storage block becomes a blank temporary storage block. If there is information about personnel waiting to enter, but this information does not meet the corresponding door opening rules, the reason for the door not opening is displayed. All data in the current temporary storage block is transferred to the first blank storage block in the storage blockchain in sequence. The next temporary storage block is then determined, and the current temporary storage block becomes a blank temporary storage block. Similarly, if there is information about personnel waiting to exit, but only this information does not meet the corresponding door opening rules, the reason for the door not opening is displayed. All data in the current temporary storage block is transferred to the first blank storage block in the storage blockchain in sequence. The next temporary storage block is then determined, and the current temporary storage block becomes a blank temporary storage block.

All data in the current temporary storage block is transferred to the first blank storage block in the storage blockchain in sequence. The next temporary storage block is then determined, and the current temporary storage block becomes a blank block. If only pressure-related information is not met, personnel waiting to enter are reminded to wait. The pressure in the contaminated area and buffer zone is adjusted to P. 污 <P 缓 Control A3 进 The instruction opens the corresponding door and simultaneously closes the other doors, transferring all data in the current temporary block to the first blank storage block in the storage blockchain, determining the next temporary block, and making the current temporary block a blank temporary block; if the protective measures worn by the personnel waiting to enter do not meet the requirements, the reason why the door does not open is reminded, all data in the current temporary block is transferred to the first blank storage block in the storage blockchain, determining the next temporary block, and making the current temporary block a blank temporary block.

[0040] When the instruction is one, specifically A2 出 instruction, it is determined whether the person waiting to go out has completely removed the protective measures, and P 缓 <P 洁 , if yes, A2 出 instruction corresponding door (air-tight electronic lock on the door of the buffer area) is controlled to open, while the remaining doors are closed, all data in the current temporary block is moved to the first blank storage block in the storage block chain in sequence, the next temporary block is determined, and the current temporary block becomes a blank temporary block; when only the pressure-related information does not meet the requirement, the person waiting to go out is reminded to wait, the pressures of the buffer area and the cleaning area are adjusted to make P 缓 <P 洁 , A2 出 instruction corresponding door is controlled to open, while the remaining doors are closed, all data in the current temporary block is moved to the first blank storage block in the storage block chain in sequence, the next temporary block is determined, and the current temporary block becomes a blank temporary block; when the protective measures of the person waiting to go out do not meet the requirement, the reason why the door is not opened is reminded, all data in the current temporary block is moved to the first blank storage block in the storage block chain in sequence, the next temporary block is determined, and the current temporary block becomes a blank temporary block.

All data in the current temporary storage block is transferred to the first blank storage block in the storage blockchain in sequence. The next temporary storage block is then determined, and the current temporary storage block becomes a blank block. If pressure-related information is not met, personnel waiting to exit are reminded to wait.
