Referring to fig. 3, fig. 3 is a flowchart illustrating a method 300 for controlling an internet of things device according to some embodiments of the disclosure. In an embodiment, the method 300 for controlling an internet of things device shown in fig. 3 may be applied to the control system 100 of the internet of things device of fig. 1 and each internet of things device 130 of fig. 2, the method 300 for controlling an internet of things device first performs step S310 of receiving and storing a device identification number corresponding to each internet of things device 130 through the inter-link server 120, and each internet of things device registers its corresponding device identification number on the first block link 110 a. In one embodiment, the first blockchain 110a may be implemented as an IOTA blockchain network and the second blockchain 110b may be implemented as an etherhouse (Ethereum) blockchain network. In one embodiment, the processor 131 of the internet of things device 130 sets the device id corresponding to each internet of things device 130 after installing the deployment software of the internet of things, and then registers the device id on the inter-link server 120 and the first blockchain 110a (IOTA blockchain network), so that the internet of things device 130 becomes a device capable of connecting to the IOTA blockchain network. Then, the inter-chain server 120 receives and stores the device identifier corresponding to each internet of things device 130, and the internet of things device 130 registers the corresponding device identifier on the first blockchain 110 a.
As mentioned above, the first block chain 110a (IOTA block chain network) may be used to control the status of the internet of things device 130, and the second block chain 110b (etherhouse block chain network) is used to record the status of the internet of things device and the transaction with the electronic device 140.
Next, the method 300 for controlling the internet-of-things device executes step S320 to fill the device identification number into the corresponding intelligent contract through the cross-link server 120, and executes step S330 to deploy the intelligent contract to the second blockchain 110b to generate a contract identification number of the corresponding intelligent contract and store the corresponding device identification number. Continuing with the above embodiment, after the internet-of-things device 130 is connected to the first block chain 110a and registers the device identification number, the device identification number is transmitted to the inter-link server 120, the inter-link server 120 fills the device identification number corresponding to each internet-of-things device 130 into the intelligent Contract, the intelligent Contract stores the device identification number of each internet-of-things device 130, and the intelligent Contract is deployed to the second block chain 110b to generate a Contract identification number, where the Contract identification number is a Contract Address (Contract Address) for calling the intelligent Contract. In this way, each internet of things device 130 can correspond to one intelligent contract and the contract identification number corresponding to the intelligent contract.
Next, the method 300 for controlling the internet of things devices executes step S340, and transmits the contract identification number of each internet of things device to the merchant server 150 through the chain server 120. In the above embodiment, after receiving the contract identifier, the inter-link server 120 indicates that the internet of things device 130 is deployed on the second blockchain 110b, so that the second blockchain 110b may track the internet of things device 130 through the inter-link server 120, then synchronize the contract identifier corresponding to each internet of things device 130 to the merchant server 150, and the merchant server 150 records the corresponding status of each internet of things device 130. The completion of steps S310 to S340 indicates that the internet of things device 130 has already registered in the first blockchain 110a and the second blockchain 110b, indicating that "uplink" is successful.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method 400 for controlling an internet of things device according to some embodiments of the disclosure, and fig. 5 is a flowchart illustrating a step S410 according to some embodiments of the disclosure. After the steps S310 to S340 are performed, the steps shown in fig. 4 may be performed next, and the method 400 for controlling an internet of things device performs step S410 to make a reservation request through the cross-link server 120 by using the electronic device 140. In one embodiment, step S410 is used for transmitting a request for reserving the internet of things device 130 through the electronic device 140, for example, the user can reserve the intelligent cabinet a, and step S410 further includes steps S411 to S416.
As mentioned above, the method 400 for controlling the internet of things device executes step S411, and transmits the corresponding identification number and the query request to the cross-link server 120 through the electronic device 140. In an embodiment, the user may reserve the internet of things device 130 through the electronic device 140, and send a query request to the cross-link server 120 by using the electronic device 140, where the query request refers to query all available internet of things devices 130, i.e., query all available smart cabinets in the embodiment of the present disclosure, and the identification number is the identification code of the electronic device 140.
As described above, the method 400 for controlling an internet of things device executes step S412, and provides a query request to the second block chain 110b through the inter-link server 120 according to the device identification code, so as to query the use information of the intelligent contract corresponding to each internet of things device 130; in step S413, the cross-link server 120 transmits the usage information corresponding to each internet of things device 130 to the electronic device 140.

The identification number corresponds to the electronic device 140 which transmits the reservation information, and the contract identification number and the device identification number correspond to the selected intelligent cabinet a.
Next, the method 400 for controlling an internet of things device executes step S415, transmits the reservation information to the second blockchain 110b through the inter-link server 120, and updates the state corresponding to the selected internet of things device 130; and step S416, updating the state corresponding to the selected internet of things device 130 in the merchant server 150. In one embodiment, the status of cabinet a is updated to "in use" by sending the reservation information to the second blockchain 110b through the cross-link server 120, and then updating the status of cabinet a in the merchant server 150.
In one embodiment, when the cross-link server 120 queries the intelligent contract according to the contract identifier, the cross-link server 120 generates a control command corresponding to the device identifier of the intelligent contract and transmits the control command to the first blockchain 110a, where the control command is obtained by connecting the internet-of-things device 130 corresponding to the device identifier to the first blockchain. For example, if the user requests to unlock or lock the intelligent cabinet a through the electronic device 140, the cross-link server 120 may query the intelligent contract corresponding to the intelligent cabinet a according to the contract identification number, and then the cross-link server 120 may generate a corresponding control command to be sent to the first block chain 110a, where the control intelligent cabinet a may be connected to the first block chain 110a to obtain the control command.
As described above, the method 400 for controlling an internet of things device executes step S420, and executes an intelligent contract and controls the internet of things device 130 corresponding to the intelligent contract by using the electronic device 140 through the cross-link server 120. In one embodiment, step S420 is for unlocking the intelligent cabinet a by using the electronic device 140, and step S420 further includes steps S421 to S429.
