Test the performance of the terminal.

In some specific implementations, the demand information may also include reward information, and the reward information is used to determine the information for issuing rewards to the meter supply node according to the test results obtained by the target test meter on the terminal to be tested.

In step 702, the meter demand node 610 encrypts the demand information with its own private key, generates and sends the encrypted demand information to the blockchain network, so that the protocol conversion node 620 can obtain the demand information.

Step 703, the protocol conversion node 620 obtains the encrypted demand information from the blockchain network, and uses the public key of the instrument demand node 610 to decrypt the encrypted demand information to obtain the first training information; then, according to the preset The test protocol searches the protocol database, and determines that the protocol database includes a preset test protocol and a first protocol conversion model; and generates first training information based on the preset test protocol, the first protocol conversion model and the target test protocol.

Wherein, the first protocol conversion model is used to convert the preset test protocol, so that the converted protocol matches the target test protocol used by the target test instrument.

Wherein, since different meter candidate nodes may adopt different sample data, and different meter candidate nodes obtain different model parameters to be verified during the process of training the sample data, therefore, the protocol conversion node 620 The generated multiple conversion models of the protocols to be verified are also different. Correspondingly, the preset test protocols are input into the conversion models of the multiple protocols to be verified for conversion, and the obtained multiple test protocols to be verified are also different. But the test protocol to be verified is as close as possible to the target test protocol.

In step 708, the protocol conversion node 620 sends the generated multiple test protocols to be verified to the blockchain network, so that the meter demand node 610 can select a suitable test protocol from the multiple test protocols to be verified.

Wherein, the smart contract may include a first smart contract and a second smart contract. The first smart contract includes: the first reward information and the identification of the meter supply node (i.e. the first meter candidate node 631); the first smart contract is a smart contract signed between the meter demand node 610 and the protocol conversion node 620, and the meter demand The node 610 sends the first reward information to the protocol conversion node 620 through the first smart contract, and the first reward information is used to reward the first protocol conversion model provided by the protocol conversion node 620, and the to-be The update of the first protocol conversion model to the validation model parameters is performed.

The second smart contract is a contract signed between the meter demand node 610 and the meter supply node (that is, the first meter candidate node 631 ). The second smart contract includes: the second reward information, the model parameters to be verified provided by the instrument supply node, the identification of the instrument supply node (i.e. the first instrument candidate node 631) and the identification of the instrument demand node 610, and the use of the target test instrument At least one of time information, performance parameter information of the target test instrument and quantity information of the target test instrument.

Through the second smart contract, the meter demand node 610 can use the target test meter provided by the first meter candidate node 631 and send the second reward information to the first meter candidate node 631 .

In some specific implementations, the instrument demand node 610 may also select multiple instrument candidate nodes as instrument supply nodes, so as to meet the different demands of the instrument demand node 610 for test instruments.

In this embodiment, through the protocol conversion node, the smart contract can be signed between the meter demand node and the meter supply node, so that the meter supply node can provide the meter demand node with a suitable target test meter, so that the meter demand node can use the target The test instrument needs to test the terminal to be tested, reduce the idle state of the test instrument, so that the test instrument can be used reasonably; and, through the model parameters to be verified provided by each instrument candidate node, the first protocol provided by the protocol conversion node The transformation model is updated, so that the private protocol of the test instrument can be converted into a protocol suitable for the terminal to be tested, which expands the scope of use of the test instrument.
