Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a parking space scheduling method according to an embodiment of the present invention. The embodiment of the invention provides a parking space scheduling method aiming at the technical problems in the prior art, and the method comprises the following specific steps:
The user node in this embodiment may specifically be the terminal device 31 or the terminal device 35 shown in fig. 3. Further, 32 and 33 respectively represent parking space nodes, 34 represents a timestamp server, and the terminal device 31, the terminal device 35, the parking space node 32, the parking space node 33, and the timestamp server 34 may be nodes in a block chain network. The present invention is only illustrative, and does not limit the specific structure of the blockchain network, and in other embodiments, the blockchain network may further include other nodes. In this embodiment, the parking space node may specifically be a communication device or a communication apparatus arranged in a parking lot, optionally, the parking lot has a plurality of parking spaces, and each parking space corresponds to one parking space node, or one parking space node corresponds to a plurality of parking spaces. Optionally, each parking space corresponds to one unique identification information in the block chain network.
In this embodiment, a parking space node corresponding to each parking space is taken as an example for schematic explanation. When the user of the terminal device 31 needs to reserve a parking space, the terminal device 31 sends the parking time required by the vehicle of the user and the identification information of the parking space predetermined by the user to the timestamp server 34, and it can be understood that the parking time required by the vehicle of the user is the time period in which the parking space predetermined by the user is occupied.
Alternatively, the terminal device 31 signs the parking time required for the vehicle of the user and the identification information of the parking space predetermined by the user with its own private key, and sends the signature to the timestamp server 34.
When the time stamp server 34 receives the parking time required by the vehicle of the user and the identification information of the parking space predetermined by the user, which are sent by the terminal device 31, the time stamp server 34 assigns a time stamp to the parking time required by the vehicle of the user and the identification information of the parking space predetermined by the user, and optionally, the time stamp is a time stamp local to the time stamp server 34 when the time stamp server 34 receives the parking time required by the vehicle of the user and the identification information of the parking space predetermined by the user, which are sent by the terminal device 31. The time stamp server 34 may transmit the time stamp, the time required for parking the user vehicle signed by the terminal device 31, and the identification information of the parking space predetermined by the user to the terminal device 31 together, upon receiving the time required for parking the user vehicle signed by the terminal device 31 and the identification information of the parking space predetermined by the user. Optionally, the timestamp server 34 signs the timestamp, the parking time required by the vehicle of the user signed by the terminal device 31, and the identification information of the parking space predetermined by the user with its own private key, and then sends the signature to the terminal device 31.
When the terminal device 31 receives the time stamp signed by the time stamp server 34, the parking time required for the user vehicle and the identification information of the parking space reserved by the user signed by the terminal device 31, the terminal device 31 broadcasts the time stamp, the parking time required for the user vehicle and the identification information of the parking space reserved by the user into the blockchain network. Alternatively, the terminal device 31 may employ its own private key to sign the timestamp, the parking time required by the vehicle of the user, and the identification information of the parking space predetermined by the user, and then broadcast the signature to the blockchain network.
It is understood that the terminal device 35 and the terminal device 31 belong to different users, for example, the terminal device 31 corresponds to the user a, the terminal device 35 corresponds to the user B, and the terminal device 31 broadcasts the parking time required for the vehicle of the user a, the identification information of the parking space predetermined by the user a, and the timestamp acquired by the terminal device 31 from the timestamp server 34 in the blockchain network. Similarly, the terminal device 35 broadcasts the parking time required for the vehicle of the user B, the identification information of the parking space predetermined by the user B, and the time stamp acquired by the terminal device 35 from the time stamp server 34 in the blockchain network.
Optionally, the parking space reserved by the user a and the parking space reserved by the user B may be the same, that is, the identification information of the parking space reserved by the user a and the identification information of the parking space reserved by the user B may be the same, assuming that the parking space reserved by the user a and the parking space reserved by the user B are the same, the parking space node corresponding to the parking space reserved by the user a and the parking space reserved by the user B is the parking space node 32, the parking space node 32 may receive the parking time required for the vehicle of the user a and the identification information of the parking space reserved by the user a transmitted from the terminal device 31 and the timestamp acquired by the terminal device 31 from the timestamp server 34 within a preset time range, and receiving the parking time required for the vehicle of the user B, the identification information of the parking space predetermined by the user B, and the time stamp acquired by the terminal device 35 from the time stamp server 34, which are transmitted by the terminal device 35. In other embodiments, the terminal devices in the blockchain network are not limited to the terminal device 31 and the terminal device 35, that is, the parking space node 32 may also receive the parking time required by the vehicle of the other user, the identification information of the parking space reserved by the other user, and the timestamp acquired by the other terminal device from the timestamp server 34, which are sent by the other terminal device. That is, within the preset time range, the parking space node 32 may receive the parking time required for the vehicle of the user, the identification information of the parking space predetermined by the user, and the timestamp acquired by the terminal device from the timestamp server 34, which are sent by at least one terminal device.
In this embodiment, the parking time required for the vehicle of the user a and the parking time required for the vehicle of the user B may overlap or partially overlap, that is, the time in which the user a and the user B are expected to occupy the same parking space may conflict. In this case, the parking space node 32 may compare the timestamp acquired by the terminal device 31 from the timestamp server 34 with the timestamp acquired by the terminal device 35 from the timestamp server 34, and if the timestamp acquired by the terminal device 31 from the timestamp server 34 corresponds to a time earlier than the timestamp acquired by the terminal device 35 from the timestamp server 34, the parking space node 32 determines that the user a corresponding to the terminal device 31 occupies the parking space within the vehicle required parking time of the user a. That is, the terminal device 31 is a target user node determined by the parking space node 32 from the terminal device 31 and the terminal device 35. And vice versa, and will not be described in detail herein.
Optionally, when the user node is the target user node, the user node and the parking space node sign an intelligent contract, where the intelligent contract includes signature information of the user node and signature information of the parking space node.
For example, the terminal device 31 is a target user node determined by the parking space node 32 from the terminal device 31 and the terminal device 35, and the terminal device 31 and the parking space node 32 sign an intelligent contract, where the intelligent contract may specifically include identification information of the parking space node 32 and the terminal device 31 in a blockchain network, a time period for the terminal device 31 to reserve and occupy a parking space corresponding to the parking space node 32, parking charge information, and the like. Optionally, the intelligent contract may be generated by the parking space node 32, the parking space node 32 generates the intelligent contract, signs a signature with its own private key and broadcasts the signature to the blockchain network, and after the terminal device 31 receives the intelligent contract sent by the parking space node 32 from the blockchain network, the terminal device 31 broadcasts the intelligent contract to the blockchain network after signing the intelligent contract again with its own private key, so that the intelligent contract takes effect formally. After the terminal device 35 receives the intelligent contract sent by the parking space node 32 from the blockchain network, it is determined that the terminal device 31 and the parking space node 32 sign the intelligent contract, and then the user B corresponding to the terminal device 35 may continue to select another parking space for reservation, or select another time period of the same parking space reserved by the terminal device 31 and the terminal device 35.
In addition, in other embodiments, after the user node signs an intelligent contract with the parking space node, the method further includes: and the user node broadcasts transfer information in the block chain network according to the intelligent contract, wherein the transfer information is used for showing that the user node transfers money to the target parking space node.
After the parking space node 32 and the terminal device 31 sign an intelligent contract, the user of the terminal device 31 arrives at the parking space corresponding to the parking space node 32 according to the time period that the user vehicle agreed in the intelligent contract occupies the parking space, further, the terminal device 31 sends transfer information to the parking space node 32 according to the parking charge information agreed in the intelligent contract, and optionally, the terminal device 31 broadcasts the transfer information in the block chain network. Optionally, the terminal device 31 signs the transfer information with its own private key and broadcasts the signed transfer information to the blockchain network.
The embodiment of the invention sends the parking time required by the vehicle of the user and the identification information of the parking space preset by the user to the time stamp server through the user node, the time stamp server distributes the time stamp to the information sent by the user node, the user node broadcasts the time stamp distributed by the time stamp server, the parking time required by the vehicle of the user and the identification information of the parking space preset by the user to the block chain network, when the user node and other user nodes reserve the same parking space and the time of the user node and other user nodes expecting to occupy the parking space conflicts, the parking space node that this parking stall corresponds determines the user who occupies this parking stall according to the timestamp that this user node and other user nodes obtained from the timestamp server respectively, avoids the timestamp to be forged, has improved the fairness that the parking stall reservation was occupied.

Optionally, the parking space node signs the identification information, the location information, the charging information, the right information, and the public key of the parking space node by using its own private key and broadcasts the signature information, the location information, the charging information, the right information, and the public key of the parking space node to the block chain network.
In other real-time examples, the parking space node may further broadcast the identification information of the parking space and the public key of the parking space node as the identity information of the parking space in the blockchain to the blockchain network. Optionally, the parking space node signs the identification information of the parking space and the public key of the parking space node by using its own private key and broadcasts the information to the block chain network.

Optionally, in other embodiments, when the state of the parking space changes, the parking space node broadcasts the state information of the changed parking space to the blockchain network, and if the state information of the parking space does not change after a certain time threshold, the parking space node corresponding to the parking space broadcasts the state information of the parking space in the blockchain network at a fixed time interval.
In this embodiment, assuming that a certain parking space is already occupied, for example, the parking space corresponding to the parking space node 32 is already occupied, the parking space node 32 broadcasts the information that the parking space is occupied to the block chain network.
Alternatively, the parking space corresponding to the parking space node 32 has been reserved by the user, and the parking space node 32 broadcasts reservation information of the parking space reserved by the user to the blockchain network, where the reservation information may include the occupied time period of the parking space.
