Background
Along with the continuous development of the building field, the intelligent degree of the building is higher and higher, and the quantity of intelligent equipment in the building is more and more. There is much research on the existing intelligent building management system based on the block chain, but the number of devices involved is small, and the throughput requirement on the block chain is low. As the number of devices increases, the number of access operations for data in the blockchain also increases greatly, and the throughput of the conventional blockchain cannot meet the use requirement. Meanwhile, the intelligent device also has certain calculation and storage capacity, and can perform data processing or statistical operation which can be achieved by some force, but the precious calculation force resources are not fully utilized at present.
Although scholars at home and abroad have made more researches on the application of the block chain in the internet of things. For example, an automatic energy-saving control system for equipment based on a block chain uploads the energy consumption condition of the equipment and an energy-saving threshold value to the block chain, and an intelligent contract of the block chain automatically monitors whether the energy consumption of the equipment reaches the energy-saving threshold value and determines whether an energy-saving mode of the equipment needs to be started according to a monitoring result; or a humiture automatic detection alarm system based on the block chain uploads humiture threshold values and humiture data monitored by a sensor to the block chain, and intelligent contracts of the block chain automatically monitor whether the humiture reaches the threshold values and judge whether alarm is needed according to monitoring results; the intelligent home system based on the block chain realizes access control of system data by using the block chain, thereby protecting the safety of the system data; and a building management system based on the block chain, which realizes the storage and access control of distributed equipment data in the building by using the block chain.
However, although the above researches all use the blockchain to realize safe and reliable data storage and data access control, the number of devices involved therein is small, and the throughput of the existing blockchain can still meet the use requirement. However, as the number of devices in a building is continuously increased, the requirement on the throughput rate of the block chain is higher and higher, and the throughput rate of the existing block chain cannot meet the actual use requirement. In addition, some of the devices in the above-mentioned research have certain computing and storage capabilities, and can perform some data processing or statistical operations, but these precious computing resources are not effectively utilized.

s432: the schematic diagram of the transmission protocol by the eight diagrams is shown in fig. 7, and the main flow of the broadcast event is as follows: the local node assembles newly received data and signature information of the data received from other nodes into an event, and then randomly sends the event to a target node; after receiving the event, the target node reads and stores the data (event content) in the event, then assembles the data in the event and the information collected from other nodes into a new event, then sends the new event to other randomly selected nodes, and repeats the process until all the nodes receive the event created at the beginning;
s433: when all nodes receive the event created at the beginning, all nodes need to execute the virtual voting algorithm locally to reach a consensus on the event. The virtual voting algorithm mainly comprises three steps of round determination, famous witness determination and data validity voting collection, and consensus round number and consensus time determination:
(1) and (3) determining the turns: the first event sent by a node is a witness event, and the witness event is the beginning of a round (R) for the node. Assuming that after node B receives event X sent by node a, node B will select node C as the receiving node, node B creates event P (which includes data known to node B but not to node C) and sends P to node C, before creating event P, node B should check if it needs to start a new round, if event X can see most witnesses in round R, event P is the start of round R +1 and P is the witness in round R + 1.
Otherwise, event P is still in R round;
(2) witness determination and data validity vote collection: when judging whether the witness in the round R is a known witness, the witness in the round R +1 is required to judge, and then the witness in the round R +2 is used to count whether the witness is a known witness and whether the data contained in the witness event in the round R is valid. If the witness of the node B of the round R +1 can see the witness of the node A of the round R, the witness of the node B of the round R +1 casts a known witness ticket to the witness of the node A of the round R. The witness of the C node of the round R +2 collects the number of tickets which can be strongly seen by the witness of the B node (or other nodes) of the round R +1 and proves that the A node is the well-known witness, and when the number of tickets exceeds two thirds of the number of the nodes, the witness of the A node is the well-known witness. Data contained in practice is valid when the number of votes for which the collected data is valid exceeds the number of 1/2 nodes.
(3) Determining the number of consensus rounds and the consensus time: when the witnesses in round R all determine whether they are known witnesses, then the round of receipt of events that can be seen by all the witness in round R is R. Event P to each witness node where it is visible, the earliest event to see P, such as: if the event P is visible at the node A and the node A, B, C, the node A can see the P as the P at the earliest, the node B can transmit the P to the node B for the first time, the node C and the node B can find the median of the time stamps in the three events as the common identification time stamp of the event P, and the information of the common identification time stamp, the number of common identification rounds, the effective ticket number obtained by the data, whether the data is effective and the like is stored in the block chain.
Wherein the terms appearing in Step3 are defined as follows:
the method comprises the following steps: when a certain event is seen by most of the visitors, the event enters the next round;
② most: 2/3 exceeding the total number of nodes;
③ see: when block B can find block A along the hash pointer, B is called visible A;
and fourthly, the witness: the first event created by each node in each round is called the witness of the round;
the fifth step is that: when the event B crosses most of the events in the path of the event A, the event B is called to be strongly visible A;
sixthly, the famous witness: the witnesses in round R are called known witnesses if they can be seen by the vast majority of the witnesses in round R + 1.
