step 4-2: when a user or a construction unit initiates an order component command, an orderPC function is called to retrieve the query parameter value input by the user, all component information in an order is newly added in a block chain account book database, the component information comprises a prefabricated component number, a prefabricated component name, the number of the prefabricated components, the state of the prefabricated components, a specified delivery date and operation time, and the state information of the corresponding components is written into an order state;
step 4-3: when a user or a production factory initiates a production component command, a ProducePC function is called to retrieve the query parameter value input by the user, determine the name and the number of a component for production operation, update corresponding component information in an account book database, supplement component production process, process starting time, process ending time and specified delivery date, and write corresponding component state information as a production state;
step 4-4: when a user or a transportation unit initiates a component transportation command, a transportPC function is called to retrieve an inquiry parameter value input by the user, determine the name and the number of a component for transportation operation, update corresponding component information in an account book database, supplement a vehicle number, a vehicle name, a transportation route, transportation starting time, transportation ending time and a specified delivery date, and write corresponding component state information into a transportation state;
step 4-5: when a user or a transportation unit initiates a delivery component command, a deliverer PC function is called to retrieve an inquiry parameter value input by the user, determine the serial number of a component for delivery operation and the serial number of a transportation vehicle, update corresponding component information in an account book database, supplement the delivery date of the component, the specified delivery date and the serial number of the component with unqualified quality, and write the state information of the corresponding component into a delivery state;
step 4-6: when a certain user of the prefabricated supply chain wants to inquire the state information of the components, the queryPC function is called to retrieve the inquiry parameter values input by the user, determine the names and the numbers of the prefabricated components needing to be operated, then inquire the component information from the block chain book database, and return the quantity information, the state information, the specified delivery date and the information of each working operation time of the components to be inquired.
6. The prefabricated supply chain multi-subject information coordination method of assembled building according to claim 5, characterized in that, in Step2, a shared ledger information structure is defined, specifically:
basic information of the member { number of the prefabricated member, name of the prefabricated member, number of the prefabricated member, state of the prefabricated member, specified delivery date, operation time };
component status information { order, production, transportation, delivery };
the component production information { prefabricated component number, prefabricated component quantity, production process, process start time, process end time, stipulated delivery date };
component delivery information { vehicle ID, prefabricated component number, number of prefabricated components, transportation route, transportation start time, transportation end time, prescribed delivery date };
component delivery information { vehicle ID, prefabricated component number, number of prefabricated components, delivery date, specified delivery date, defective component ID }.
7. The method for coordinating information of multiple main bodies of the prefabricated supply chain of the fabricated building according to claim 1, wherein the step3) is specifically as follows:
operation request and verification: in a multi-channel multi-node peer-to-peer type block chain network which is built by using a superridger fabric and is based on a block chain technology, a main body of a supply chain of an assembly type building presents a transaction request to a benefit related party, namely a endorsement node, through a client by a client identity before carrying out order, production, storage and delivery operations;
the endorsement node verifies the rationality of the request after receiving the request and returns a virtual transaction result with an endorsement signature;
the sequencing node sequences and integrates all transaction requests in a certain time period of the corresponding channel into a new block according to a certain rule, and broadcasts the new block to all other nodes of the corresponding channel for further verification.
