Description

Technical Field

[0001] The present invention relates to the fields of biosafety laboratories and blockchain technology, and in particular to a blockchain-based biosafety laboratory personnel entry and exit management method and system. Background Art

[0002] High-level biosafety laboratories primarily consist of contaminated areas, buffer zones, and clean areas. To ensure the safety of personnel entering and exiting high-level biosafety laboratories, effective access management is essential. The inventors of this invention previously applied for a patent application number and titled "A High-Level Biosafety Laboratory Control System." This invention further optimizes this patent by utilizing blockchain technology to prevent tampering with personnel access data and achieve optimized access management.

[0003] There is currently a patent application numbered 202210935110.1, entitled "A Laboratory Management Method and System Based on Blockchain." Although this patent mentions blockchain-based user access management technology, the blockchain is used to store various compliance identities. When managing and authenticating the user's access rights, the entered identity data is matched with the compliance identity information on the blockchain. If a match is made, the user can enter the laboratory, otherwise they cannot. This technology does not use blockchain to determine whether a user is allowed to enter the laboratory. The blockchain only serves to put the compliance identity on the chain, and the entire process of biosafety laboratory personnel entry and exit management of the present invention requires the participation of the blockchain. This existing patent is aimed at general laboratories and is not suitable for high-level and complex biological laboratories. Summary of the Invention

[0004] In response to the problems and shortcomings of the existing technology, the present invention provides a blockchain-based biosafety laboratory personnel entry and exit management method and system.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention provides a method for managing the entry and exit of biosafety laboratory personnel based on blockchain. A high-level biosafety laboratory has multiple zones, which are characterized by:

[0007] S1. Pre-construct a circular blockchain consisting of M temporary storage blocks and a storage blockchain consisting of N storage blocks. The circular blockchain includes two smart contracts. The first smart contract includes temporarily storing one input and one output instruction for the same zone with the same timestamp in the same temporary storage block, and temporarily storing multiple instructions for different zones in different temporary storage blocks in sequence according to instruction priority. The second smart contract includes the door opening rules corresponding to each input / output instruction.

[0008] S2. Receive the instruction, and temporarily store the instruction and its timestamp, along with the door opening rule for the instruction obtained based on the second smart contract, in a corresponding temporary storage block according to the first smart contract. Collect relevant information corresponding to the instruction and temporarily store it in the temporary storage block for the instruction.

[0009] Continuously loop through the loop blockchain to determine whether there is an instruction in the current temporary block. If so, determine whether the collected relevant information meets the corresponding door opening rules. If so, control the door corresponding to the instruction to open and control the remaining doors to close. Move all data in the current temporary block to the first blank storage block in the storage blockchain in sequence. Determine the next temporary block and the current temporary block becomes a blank temporary block. Otherwise, remind the reason why the door is not opened. Move all data in the current temporary block to the first blank storage block in sequence in the storage blockchain. Determine the next temporary block and the current temporary block becomes a blank temporary block. If there is no instruction in the current temporary block, determine the next temporary block.

[0010] The present invention also provides a biosafety laboratory personnel entry and exit management system based on blockchain, wherein a high-level biosafety laboratory has multiple zones, and is characterized in that the system includes a control center;

[0011] The control center is used to pre-build a circular blockchain consisting of M temporary storage blocks and a storage blockchain consisting of N storage blocks. The circular blockchain includes two smart contracts. The first smart contract includes a command with the same timestamp for the same zone, one entry and one exit command, which are temporarily stored in the same temporary storage block. Multiple commands for different zones are temporarily stored in different temporary storage blocks in sequence according to the command priority. Commands with different timestamps are temporarily stored in different temporary storage blocks in sequence according to the time sequence of the command timestamps. The second smart contract includes the door opening rules corresponding to each entry / exit command.

[0012] The control center is further configured to receive an instruction, temporarily store the instruction and its timestamp, and the door opening rule for the instruction obtained based on the second smart contract, in a corresponding temporary storage block according to the first smart contract, and collect relevant information corresponding to the instruction and temporarily store it in the temporary storage block of the instruction;

[0013] The control center is also used to continuously loop through the loop blockchain to determine whether there is an instruction in the current temporary storage block. If so, it determines whether the collected relevant information meets the corresponding door opening rules. If so, it controls the door corresponding to the instruction to open and controls the remaining doors to close. 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 determined, and the current temporary block becomes a blank temporary block. Otherwise, the reason why the door is not opened is reminded. All data in the current temporary block is transferred to the first blank storage block in sequence in the storage blockchain. The next temporary block is determined, and the current temporary block becomes a blank temporary block. If there is no instruction in the current temporary block, the next temporary block is determined.

[0014] The positive progress effect of the present invention is:

[0015] The present invention constructs a temporary circular blockchain for analyzing instructions and related information, and a storage blockchain for storing the final analysis results. Two smart contracts are constructed in the circular blockchain. The first smart contract is used to specify the temporary storage location of each instruction, and the second smart contract is used to specify the door opening rules corresponding to each entry / exit instruction. Based on these two smart contracts, it can be analyzed whether the corresponding door is opened for each instruction in the temporary storage block in the circular blockchain.

[0016] 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 the cross-mixing of air in each area, thereby ensuring the life safety of personnel entering and exiting the biosafety laboratory, the environmental safety of the biosafety laboratory, and preventing the leakage of harmful biological factors in biosafety experiments.

[0020] like Figure 1 As shown, the high-level biosafety laboratory is divided into clean area, buffer area and contaminated area in sequence. The clean area is equipped with doors for personnel to enter and exit. The entrance and exit of the clean area correspond to A1 进 Instructions and A1 出 Instructions: The buffer zone is equipped with doors for personnel to enter and exit. The entry and exit of the buffer zone correspond to A2 进 Instructions and A2 出 Instructions: There are doors in the contaminated area for personnel to enter and exit. The entry and exit of the contaminated area correspond to A3 进 Instructions and A3 出 instruction.

[0021] Example 1

[0022] The embodiment of the present invention provides a method for managing the entry and exit of biosafety laboratory personnel based on blockchain, comprising the following steps:

[0023] The first step is to pre-build a circular blockchain (consisting of M temporary blocks) and a storage blockchain (consisting of N storage blocks). The circular blockchain includes two smart contracts. The first smart contract includes one entry and one exit instruction with the same timestamp for the same zone, which are sequentially stored in the same temporary block. Multiple instructions with the same timestamp for different zones are sequentially stored in different temporary blocks according to the instruction priority. Instructions with different timestamps are sequentially stored in different temporary blocks according to the time sequence of the instruction timestamps. The second smart contract includes the door opening rules corresponding to each entry / exit instruction. Among them, the instruction priority is A3 出 Command > A2 出 Command > A1 出 Command > A3 进 Command > A2 进 Command > A1 进 Instruction, M and N are both positive integers, and M<N.

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

[0025] In this step, at the same time, multiple instructions for different areas are sequentially temporarily stored in different temporary storage blocks according to the instruction priority. For example, if A1 进 Instruction and A2 出 Instruction are received, then A2 出 Instruction is temporarily stored in a temporary storage block first, and then A1 进 Instruction is temporarily stored in the subsequent temporary storage block.

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

[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 enter is within the preset body temperature range, the identity of the person to enter is within the preset authorization 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 enter wears protective measures matching a 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 leave 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 leave has completely removed the protective measures, and P 缓 <P clean.

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

[0033] Step 2: Receive the instruction, and temporarily store the instruction and its timestamp together with the door opening rule of the instruction obtained based on the second smart contract in the corresponding temporary storage block according to the first smart contract, and collect relevant information corresponding to the instruction and temporarily store it in the temporary storage block of the instruction; the relevant information corresponding to the instruction includes pressure-related information corresponding to the instruction and / or information related to the person waiting to enter / exit corresponding to the instruction.

[0034] Continuously loop through the blockchain to determine whether there is an instruction in the current temporary block. If so, determine whether the collected relevant information meets the corresponding door opening rules. If so, control the door corresponding to the instruction to open and control the remaining doors to close. Move all data in the current temporary block to the first blank storage block in the storage blockchain in order, determine the next temporary block, and change the current temporary block to a blank temporary block. When only the pressure-related information does not meet the corresponding door opening rules, remind the people waiting to enter / exit to wait, adjust the pressure of the relevant area so that the pressure-related information meets the corresponding door opening rules, and control the instruction to The corresponding door is opened and the other doors are controlled to be closed at the same time. All data in the current temporary block are transferred to the first blank storage block in the storage blockchain in order. The next temporary block is determined and the current temporary block becomes a blank temporary block. When there is relevant information about the person to be entered / exited and the relevant information about the person to be entered / exited does not meet the corresponding door opening rules, the reason why the door is not opened is reminded. All data in the current temporary block are transferred to the first blank storage block in order in the storage blockchain. The next temporary block is determined and the current temporary block becomes a blank temporary block. If there is no instruction in the current temporary block, the next temporary block is determined.

[0035] A further optimized technical solution is to determine whether there is an instruction in the current temporary storage block. If so, when there is only one instruction, determine whether the collected information related to the instruction meets the corresponding door opening rules. If so, control the door corresponding to the instruction to open and control the remaining doors to close. Move all data in the current temporary storage block to the first blank storage block in the order of the storage blockchain, determine the next temporary storage block, and change the current temporary storage block to a blank temporary storage block. When only the pressure-related information in the instruction-related information does not meet the corresponding door opening rules, remind the people waiting to enter / exit to wait, adjust the pressure in the relevant area so that the pressure-related information meets the corresponding door opening rules, control the door corresponding to the instruction to open and control the remaining doors to close. Move the data to the first blank storage block in the storage blockchain in order, determine the next temporary block, and change the current temporary block to a blank temporary block; when there is information about the person to be entered and the information about the person to be entered does not meet the corresponding door opening rules, remind the reason why the door is not opened, and move all the data in the current temporary block to the first blank storage block in order in the storage blockchain, determine the next temporary block, and change the current temporary block to a blank temporary block; when there is information about the person to be exited and only the information about the person to be exited does not meet the corresponding door opening rules, remind the reason why the door is not opened, and move all the data in the current temporary block to the first blank storage block in order in the storage blockchain, determine the next temporary block, and change the current temporary block to a blank temporary block.

All data in the current temporary block are transferred to the first blank storage block in the order of the storage blockchain. The next temporary block is determined, and the current temporary block becomes a blank temporary block. When only the pressure-related information is not satisfied, the personnel waiting to enter are reminded to wait, and the pressure of the clean area is adjusted so that P 洁 <P 外 , control A1 进 The door corresponding to the instruction opens and the remaining doors are controlled to close at the same time. All data in the current temporary storage block is transferred to the first blank storage block in the storage blockchain in order. The next temporary storage block is determined and the current temporary storage block becomes a blank temporary storage block. When the temperature and / or identity of the person waiting to enter does not meet the requirements, the reason why the door is not opened is reminded.

[0047] The control center is used to pre-build a circular blockchain consisting of M temporary storage blocks and a storage blockchain consisting of N storage blocks. The circular blockchain includes two smart contracts. The first smart contract includes one input and one output instruction with the same timestamp for the same zone temporarily stored in the same temporary storage block, and multiple instructions for different zones are temporarily stored in different temporary storage blocks in sequence according to the instruction priority. Instructions with different timestamps are temporarily stored in different temporary storage blocks in sequence according to the time sequence of the instruction timestamps. The second smart contract includes the door opening rules corresponding to each input / output instruction.

[0049] The control center is also used to continuously loop through the loop blockchain to determine whether there is an instruction in the current temporary storage block. If so, it determines whether the collected relevant information meets the corresponding door opening rules. If so, it controls the door corresponding to the instruction to open and controls the remaining doors to close. 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 determined, and the current temporary block becomes a blank temporary block. Otherwise, the reason why the door is not opened is reminded. All data in the current temporary block is transferred to the first blank storage block in sequence in the storage blockchain.

[0053] Example 2

[0054] The embodiment of the present invention optimizes the first smart contract based on embodiment 1. In the first smart contract, instructions with different timestamps are temporarily stored in different temporary blocks in sequence according to the time sequence of the instruction timestamps. If the same instruction for the same area is received before and after and the door opening or door reminder reason operation for the previous instruction has not been implemented, the latter instruction will be placed in the same temporary block as the previous instruction. If one-in-one-out instruction or one-out-one-in instruction for the same area is received before and after and the door opening or door reminder reason operation for the previous instruction has not been implemented, the latter instruction will be placed in the same temporary block as the previous instruction.

[0055] For example, if the same person waiting to enter or exit issues the same command multiple times before the door is opened or before the reason why the door is not opened is reminded, the multiple identical commands can be regarded as one command and stored in the same temporary storage block.

[0056] A1 is issued to those waiting to enter 进 Instructions, followed by the personnel waiting to go out to issue A1 出 Instruction, that is, the person waiting to leave sends A1 to the person waiting to enter 进 A1 is issued before the door opening instruction or the door not opening reason operation is executed 出 Instruction, you can set this A1 进 Instructions and A1 出 The instructions are treated as one in and one out at the same time and stored in the same temporary buffer block.

[0057] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
