2. A synchronous recording device for bank vault cash access, characterized in that the device is applied to nodes in a blockchain, each node is provided with a monitoring server, a cash recording system of each bank vault is provided with a monitoring agent terminal, and the device comprises:
the change information receiving unit is used for receiving the cash amount change information of the cashbox sent by the monitoring agent terminal in a preset monitoring range, wherein the communication mode between the monitoring agent terminal and the monitoring server is any one of the existing communication modes, in order to improve the safety of data transmission, the monitoring agent terminal sends the encrypted cash amount change information of the cashbox to the monitoring server by adopting an encryption transmission mode, and the monitoring server decrypts the cash amount change information of the cashbox to obtain the cash amount change information of the cashbox;
the change information analysis unit is used for analyzing the cash amount information of the cashbox to obtain cash access data of the cashbox, and the cash access data of the cashbox comprises: bank vault identification, access time, cash amount and cash allowance;
an access data storage unit for storing the vault cash access data in each node of a blockchain;
the device further comprises a risk prediction unit, which is specifically configured to:
after the cashbox cash access data are stored, determining whether a bank cashbox corresponding to the cashbox cash access data is a risk supervision target according to the corresponding relation between a prestored bank cashbox identifier and a risk supervision range;
under the condition that the bank vault corresponding to the vault cash access data is a risk supervision target, acquiring the vault cash access data of the risk supervision target in a preset time period through inquiring a blockchain;
inputting the cash access data of the cashbox of the risk supervision target in a preset time period into a pre-constructed risk prediction model to obtain a risk prediction result of the risk supervision target;
determining whether to send risk early warning prompt information to risk supervision nodes in a blockchain according to a risk prediction result of the risk supervision target;
the device further comprises a risk prediction result storage unit, wherein the risk prediction result storage unit is specifically used for storing a risk prediction result of the risk supervision target in each node of a blockchain;
the device also comprises a cash dispatching unit, which is specifically used for:
under the condition that cash dispatching requirements are received, analyzing the cash dispatching requirements, and determining the position of a user and the cash demand;
acquiring cash margins, risk prediction results and distances between the cash margins and the risk prediction results of each bank vault and the user position in a preset range of the user position by querying a blockchain;
determining a cash dispatching target corresponding to the cash dispatching requirement according to the cash demand, cash allowance of each bank vault within a preset range of the user position, a risk prediction result and a distance between the cash allowance and the user position
The cash dispatching strategy is a dispatching strategy based on multi-objective optimization, the general principle is that the cash allowance is the largest, no risk exists, the distance between the cash allowance and the user position is the shortest, weights of the cash allowance and the distance between the cash allowance and the user position are set, and the optimal cash dispatching objective is determined through a weighted summation method.
3. A synchronous recording system for bank vault cash access, comprising: a cash recording system of a blockchain and at least one bank vault;
each node in the blockchain is provided with a monitoring server for executing the bank vault cash access synchronous recording method according to claim 1;
the cash recording system of the bank vault is provided with a monitoring agent terminal;
the monitoring server communicates with the monitoring agent terminals within the monitoring range.
