In order to verify the effectiveness of the provided intelligent payment method for the electric power infrastructure expense based on the block chain intelligent contract technology, in a laboratory environment, a Remix IDE platform is used for compiling an intelligent contract for paying the electric power infrastructure expense to perform example simulation. The operating systems of all the subjects in the laboratory are Windows 10, the memory is 169B, the CPU is Intel Core i5, and the edition of the writing environment Remix of the intelligent contract is v0.5.10. The simulation scene comprises an owner, a head bag, a sub-package, a bank, a proctor and a team account, wherein 1ETH is prestored in each account of the owner. The general packet firstly stores necessary wage amount to bank wage special account, the owner verifies worker attendance information every month, after confirming that no fault exists, the contract module is called to send corresponding wage to the general packet, the general packet sends payment confirmation information to the bank after receiving the wage, and the bank calls the function module to directly pay the wage to the worker account after receiving the information.
In the simulation test, taking monthly wage payment of workers as an example, the construction period of a project is one year, monthly wage is 1 token, 12 tokens which need to be paid in one year are stored in a bank account in advance in a general packet, then each month owner distributes wage to the general packet after verifying the attendance condition of the workers, the general packet informs a bank calling function module to directly distribute the monthly wage to the workers after receiving the wage, and the simulation result of transaction information of the wage distributed to the general packet on Remix after each month owner verifies the attendance of the workers is shown in fig. 5.
Fig. 5 is a complete return information table, from which information such as a hash value of a transaction, whether the transaction is successful, transaction time, an account address where the transaction is initiated, an output account address of the transaction, a token transfer amount, a gasoline (gas) fee, and a called function module can be seen.
The result of simulation of transaction information on Remix by bank call function module to distribute monthly wages directly to workers is shown in fig. 6. It can be seen from the block transaction information that the bank calls two modules together, sends a token to the worker account, and declares a work event on the blockchain for monitoring by other nodes.
By calling the preset expense payment module, the corresponding amount of digital token is directly attached to each link of the electric capital expense payment, and the attribution party of the digital currency is changed while the node confirms the transaction, so that the synchronization of the transaction and the clearing is realized, and funds are transferred in real time in the transaction.
Compared with the prior art, the invention can effectively ensure the standard management in various aspects of construction progress, quality, safety and the like, and provides a customized function for the development of electric power capital construction payment business.
The method can effectively improve the automation level of the payment of the electric power infrastructure expense, improve the transparency of the expense payment process, relieve the problem that the wage payment of workers is not timely, and make up the defects in the field of the payment of the electric power infrastructure expense.
