[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm. It is essentially a decentralized database.

[0039] In the embodiment of the present application, first, a blockchain network can be deployed based on a blockchain framework, wherein the blockchain framework can be any blockchain framework that can implement the corresponding functions of the embodiment of the present application, such as Bitcoin, Ethereum, Fabric, Corda, etc.

[0040] The blockchain network includes several nodes, including ship nodes, berth nodes, etc.

[0041] Afterwards, the corresponding smart contracts can be generated according to the relevant needs of ship scheduling in multi-berth ports and written into each node in the blockchain network.

[0042] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0043] Figure 1 The flowchart of the multi-berth port ship scheduling method based on blockchain provided in the embodiment of the present application includes the following specific steps:

[0044] S101: Collect information of ships to be operated.

[0045] In the embodiment of the present application, a ship docked at an anchorage and waiting for a berth to be allocated can be referred to as a waiting ship. Each waiting ship can serve as a node in the blockchain network, collect its own waiting ship information, and write it into the blockchain network.

[0046] Specifically, the information of the ship to be operated may include the type of ship, cargo capacity, waiting time, etc.

[0047] S102: Determine berth information in the blockchain.

[0048] In the embodiment of the present application, each berth of the port can also be used as a node in the blockchain network, collect its own berth information, and write it into the blockchain network. The berth information may include berth type, loading and unloading capacity, maximum draft, distance from the waterway, whether it is idle, and the fastest start time of operation.

[0049] Therefore, when there is a ship to be operated in the port, each berth node can determine its own current berth information in order to determine the berth allocated to the ship to be operated.

[0050] S103: Based on the preset smart contract, according to the information of the ship to be operated and the berth information, a berth to be scheduled for the ship to be operated is determined.

[0051] S104: Write the berth scheduling result into the blockchain.

[0052] In an embodiment of the present application, a master node may be preset in the blockchain network. When the master node detects the existence of a ship to be operated based on a preset smart contract, it may perform calculations based on the information of the ship to be operated in the blockchain and the berth information of each berth, determine the berth to be scheduled for the ship to be operated, and write the berth scheduling result into the blockchain through the PBFT consensus algorithm.

[0053] Specifically, the contents of the preset smart contract are as follows:

[0054] First, the master node monitors the information of ships to be operated in the blockchain network, and when it is determined that there are ships to be operated, it determines to allocate berths for the ships to be operated.

[0055] Second, for each berth, the master node can determine the required operation time, that is, the time required for unloading, if the ship to be operated is moored at the berth based on the cargo capacity of the ship to be operated and the loading and unloading capacity of the corresponding berth.

[0056] Third, the master node can calculate based on the fastest start time of operations at each berth and the operation time required for the ship to be operated, and determine the corresponding end time of operations at each berth when the ship to be operated is operating at each berth.

[0057] Fourth, the master node can determine the berth with the earliest operation end time from all berths according to the operation end time of each berth, and allocate it to the corresponding ship to be operated for berthing. In addition, the master node can write the berth scheduling result into the blockchain and broadcast it to all other nodes in the blockchain network. Among them, the berth scheduling result may include berth information, ship information to be operated, berthing time, etc.

[0058] In the embodiment of the present application, through the smart contract preset in the blockchain network, the master node calculates according to the information of the ship to be operated and the information of each berth to obtain the fastest completion time of the ship's operation at each berth, which is used as the basis for judging the rationality of the ship to be operated berthing at the corresponding berth.

[0059] In this way, the technical features of blockchain consensus mechanism, smart contracts, etc. can be utilized to realize the automation of ship scheduling, which is conducive to saving manpower, and can effectively improve the intelligence level of ship scheduling in multi-berth ports and realize good management of ports.

[0060] In one embodiment, when the berth node determines the berth information of the berth, if the berth is in an idle state, the fastest start operation time of the berth may be set to the current time.

[0061] In one embodiment, the type of the ship to be operated needs to match the type of the berth in order to berth at the corresponding berth.

[0062] Therefore, for the information of the ship to be operated, when the master node calculates the corresponding operation end time, if the berth type of the berth is inconsistent with the ship type to be operated, the operation end time of the berth can be set to infinity. This can effectively avoid allocating the wrong berth to the ship to be operated with inconsistent types, affecting the normal operation of the ship.

[0063] In one embodiment, the preset smart contract may also include:

[0064] If the master node determines through calculation that there are two or more berths with the same operation end time, and this time is the earliest operation end time, it means that the operation end time of the ships to be operated at these berths is the same and the earliest. Therefore, the ships to be operated can freely choose a berth from these berths to carry out the berthing operation.

[0065] In one possible implementation, the master node can determine the berth closest to the channel of the ship to be operated among the berths according to the smart contract, and use it as the berth allocated to the ship to be operated. In this way, the ship to be operated can travel the shortest distance to reach the berth, which can provide convenience for the ship to be operated and save time.

[0066] In one embodiment, the master node can monitor the completion of the operation of the ship to be operated. If the operation of the ship to be operated is completed, the master node can modify the berth information of the corresponding berth, and write the modified berth information into the blockchain and disclose it to other nodes.

[0067] In one embodiment, before arriving at the port, the ship node can collect its own pre-arrival ship information in advance and write it into the blockchain network.

[0068] Therefore, the master node can make calculations in advance based on the preset smart contract and according to the expected arrival ship information and berth information of each berth in the blockchain network to determine the pre-scheduled berths for the expected arrival ships.

[0069] In one embodiment, the actual operation end time of the vessel to be operated may be inconsistent with the pre-calculated operation end time. Therefore, the berth node can monitor the actual operation end time of the vessel to be operated at the berth.

[0070] If the actual operation end time of the ship to be operated is later than the calculated operation end time, the berth node can collect the reason for the operation delay of the ship to be operated and write it into the blockchain together with the actual operation end time.

[0071] In one embodiment, there may be multiple ships waiting for operation at the port at the same time. In this case, each ship waiting for operation can determine its own information of the ship waiting for operation, and determine its corresponding berthing priority according to the preset berthing priority system, and write the determined berthing priority into the blockchain.

[0072] Among them, factors affecting the berthing priority may include cargo type, cargo purpose, special policies, etc. The specific settings can be made as needed, and this application does not limit this.

[0073] Therefore, each berth node can allocate a berth to each ship to be operated in turn according to the berthing priority order of the multiple ships to be operated.

[0074] Based on the same idea, some embodiments of the present application also provide devices and non-volatile computer storage media corresponding to the above methods.
