[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer, the implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0052] In existing coal transactions, coal workers on site are usually required to strictly weigh and inspect the quantity and quality of the coal to be transported. In practical applications, since coal transactions are often large in quantity and high in frequency, a large amount of manpower costs are required in the process of coal transactions. In addition, the environment for coal loading and unloading operations is generally harsh, and the health of coal workers on site will also be greatly affected. In addition, since the relevant information of coal transportation is recorded manually, it is easy to record less or more coal, record quality errors, and lose the record book.

[0053] In view of this, in order to solve the problems of high labor costs, impact on the health of operators and inaccurate recorded information in existing coal transactions, the present invention provides a coal transportation recording method, system, computer equipment and storage medium.

[0054] The coal transportation recording method provided by an embodiment of the present invention is described below.

[0055] Embodiment 1:

[0056] like Figure 1 As shown, a flow chart of a coal transport recording method provided by an embodiment of the present invention is applied to Figure 2 The blockchain network shown includes:

[0057] Step S101: receiving electronic evidence to be verified sent by a coal transaction recipient for a current coal transaction, wherein the electronic evidence to be verified includes a signature made using a first private key corresponding to identity information of the coal transaction recipient.

[0058] Step S102: obtaining reference electronic evidence uploaded by the coal transaction sender for the current coal transaction, wherein the reference electronic evidence includes a signature made using a second private key corresponding to the identity information of the coal transaction sender.

[0059] Step S103: using the reference electronic evidence to verify the electronic evidence to be verified.

[0060] In one implementation, Figure 3 As shown, the electronic evidence to be verified can be verified in the following manner:

[0061] Step S1031: Determine whether the comparison result between the electronic evidence to be verified and the reference electronic evidence is consistent, if they are consistent, execute step S1032, otherwise execute step S1033.

[0062] Step S1032: Determine whether the verification result of the electronic evidence to be verified is successful.

[0063] Step S1033: Determine that the verification result of the electronic evidence to be verified is failure.

[0064] Step S104: In response to the verification result being successful, determining that the current coal transaction is a valid transaction and recording the coal transfer information corresponding to the current coal transfer.

[0065] It should be noted that when the verification result is a failure, the current coal transaction is determined to be an invalid transaction. Further, an alarm reminder can be given through an early warning method to remind the coal transaction participants to conduct traceability analysis.

[0066] It can be seen that the present invention uses blockchain technology to process the information in the coal operation process on the chain, thereby establishing transaction data with extremely high credibility between the coal transaction sender and the coal transaction receiver that is tamper-proof, can withstand inspection and audit. In addition, the solution provided by the present invention also simplifies the specific transaction process in coal transactions, and realizes the trusted transaction between the coal transaction sender and the coal transaction receiver in this cross-unit situation, which can not only reduce transaction costs and tracking and re-inspection costs, but also eliminate the concerns of both parties to the coal transaction about the untrue transaction data. Moreover, since both the coal transaction receiver and the coal transaction sender adopt an automated information collection method to obtain information, it can reduce physical harm to coal workers on site, and can also avoid the occurrence of under-recording and omission, thereby achieving the effect of reducing costs and increasing efficiency.

[0067] Embodiment 2:

[0068] like Figure 4 As shown, another flow chart of the coal transport recording method provided by the embodiment of the present invention is applied to Figure 2 The blockchain network shown includes:

[0069] Step S201: Generate a first private key in advance for a first information collection device of a coal transaction receiver; and generate a second private key in advance for a second information collection device of a coal transaction sender.

[0070] During the coal transportation process, a private key can be generated in advance for each information collection device of the participants, and the private key can be implanted into the trusted chip. The participants may include the coal transaction receiver and the coal transaction sender; accordingly, the information collection device includes the first information collection device collected by the coal transaction receiver and the second information collection device collected by the coal transaction sender. Specifically, the coal transaction sender information collection device and the coal transaction receiver information collection device may include the following information: weight measuring scale, chemical detector and image collector; accordingly, the private key includes the first private key of the coal transaction receiver and the second private key of the coal transaction sender. Furthermore, the trusted chip includes at least: a proof contract interface, an evidence verification contract interface and a communication interface.

[0071] In one case, the coal transaction recipient obtains the first coal transfer information collected by the first information collection device; generates first electronic evidence based on the first coal transfer information; and signs the first electronic evidence using the first private key to obtain the electronic evidence to be verified. Further, the first public key corresponding to the first private key is generated using an elliptic curve encryption algorithm; the identity information of the coal transaction recipient is bound to the first public key, the first binding information is obtained, and a digital certificate is issued to ensure the credibility of the current coal transaction.

[0072] In another case, the coal transaction sender obtains the second coal transportation information collected by the second information collection device; generates second electronic evidence based on the second coal transportation information; and signs the second electronic evidence using the second private key to obtain the reference electronic evidence. Further, the second public key corresponding to the second private key is generated using an elliptic curve encryption algorithm; the identity information of the coal transaction sender is bound to the second public key to obtain second binding information and issue a digital certificate to ensure the credibility of the current coal transaction.

[0073] It should be noted that the elliptic curve encryption algorithm of the above volume is only a specific implementation method for generating the corresponding public key and should not be understood as a limitation of the embodiments of the present invention. Specifically, the present invention can generate the corresponding first public key or second public key by using the elliptic curve encryption algorithm based on the first private key or the second private key, which can be expressed as K i =p i G, where p i Represents the first private key or the second private key, K i represents the first public key or the second public key, and G represents the base point of the elliptic curve.

[0074] Furthermore, through the public key infrastructure (PKI) certificate service, the key service center binds the generated public key to the entity identity of the participant, specifically, the first public key is bound to the coal transaction receiver, and the second public key is bound to the coal transaction sender, thereby obtaining the corresponding first binding information and second binding information, and issuing digital certificates respectively. Then, the first binding information and the second binding information are uploaded to the blockchain network in a transaction manner through the key service center.

[0075] Step S202: receiving electronic evidence to be verified sent by a coal transaction recipient for a current coal transaction, wherein the electronic evidence to be verified includes a signature made using a first private key corresponding to the identity information of the coal transaction recipient.

[0076] Step S203: obtaining reference electronic evidence uploaded by the coal transaction sender for the current coal transaction, wherein the reference electronic evidence includes a signature made using a second private key corresponding to the identity information of the coal transaction sender.

[0077] With respect to step S202 and step S203, it should be noted that the first coal transportation information collected by the first information collection device of the coal transaction recipient is used to generate the first electronic evidence according to the data archiving instruction. Furthermore, the first private key of the coal transaction recipient is used to sign the first electronic evidence, and the signed electronic evidence to be verified is uploaded to the blockchain network by calling the evidence contract interface in the trusted chip. The second coal transportation information collected by the second information collection device of the coal transaction sender is pre-generated into the second electronic evidence according to the data archiving instruction, wherein the second coal operation information may at least include: operation time, vehicle information and coal weight. Furthermore, the second private key of the coal transaction sender is used to sign the second electronic evidence, and the signed reference electronic evidence is uploaded to the blockchain network by calling the evidence contract interface in the trusted chip, so as to be used for comparison with the electronic evidence to be verified of the coal transaction recipient. It should also be pointed out that the signed reference electronic evidence and the signed electronic evidence to be verified are both uploaded to the blockchain network through the communication interface in the trusted chip.

[0078] Step S204: using the reference electronic evidence to verify the electronic evidence to be verified.

[0079] Step S205: In response to the verification result being successful, determining that the current coal transaction is a valid transaction and recording the coal transfer information corresponding to the current coal transfer.

[0080] It should be noted that Figure 4 The method embodiment shown has Figure 1All the beneficial effects of the method embodiments shown, in addition, Figure 4 The method embodiment shown also provides a specific method for generating private keys, public keys, and electronic evidence of the information collection devices of both parties to the transaction during the coal transaction process. By binding the identity information of both parties to the transaction with the corresponding public keys, the credibility of the current coal transaction can be further ensured.

[0081] The coal transportation recording method is explained below with reference to a specific example.

[0082] Before coal transportation, each participant (including the coal transaction receiver and the coal transaction sender) selects a private key (including the first private key and the second private key) for each information collection device i (including the first information collection device and the second information collection device), and calculates the public key (including the first public key and the second public key) by using the elliptic curve E selected by the key service center, where G is the base point of the elliptic curve. The participants implant their respective private keys into the trusted chip i. For example, the data collected by the information collection device such as the sensor can be directly encrypted and signed, and directly uploaded to the chain through the communication interface of the trusted chip in a communication manner, thereby ensuring the credibility of the data source.

[0083] Through the PKI certificate service, the key service center binds the public key of each device to the entity identity and issues a certificate. In one case, the key service center uploads the binding information to the blockchain network in the form of a transaction, for example, (Key: K i , Value: Hash(C i )) to the blockchain network to ensure the credibility of each device’s public key bound to the entity’s identity.

[0084] Specifically, the second information collection device of the coal sender may include at least a camera and a weighing component to obtain the coal sending time T sensor , vehicle identification TrainNum, coal weight Weight, and generate the second electronic evidence according to the data archiving instruction. In one case, the second electronic evidence can be generated by string concatenation, for example, generating (T sensor , TrainNum||Weight). Further, the coal sender uses the second private key corresponding to the second information collection device to access the second electronic evidence (T sensor , TrainNum||Weight) to sign and obtain the reference electronic evidence (T sensor ,TrainNum||Weight)ρ Psensor By calling the evidence contract interface in the trusted chip, the reference electronic evidence can be directly uploaded to the chain.

[0085] Specifically, the first collection device for the coal receiving party information may include at least a camera and a weighing component to obtain the coal receiving time T receive , vehicle represents TrainNum, coal weight Weigh, and generates the first electronic evidence according to the data archiving instruction. In one case, the first electronic evidence can be generated by string concatenation, for example, generating (T receive , TrainNum||Weight)'. Further, the coal recipient uses the first private key corresponding to the first information collection device to access the first electronic evidence (T receive ,TrainNum||Weight)' is signed to obtain the electronic evidence to be verified (T sensor ,TrainNum||Weight)β Psensor , call the evidence storage contract interface written in the chip, and use the communication module integrated in the chip to directly upload the electronic evidence to be verified to the chain.

[0086] The coal transportation recording system provided by the present invention is described below.

[0087] Embodiment three:

[0088] like Figure 5 As shown, it is an architecture diagram of a coal transportation record system provided by an embodiment of the present invention, including:

[0089] The information collection device 310 is used to collect the first coal transportation information of the coal transaction receiver, or collect the second coal transportation information of the coal transaction sender;

[0090] The electronic evidence generation module 320 is used to obtain first coal transportation information collected by a first information collection device of a coal transaction receiver, and generate first electronic evidence based on the first coal transportation information; and obtain second coal transportation information collected by a second information collection device of a coal transaction sender, and generate second electronic evidence based on the second coal transportation information;

[0091] The key service center 330 is used to sign the first electronic evidence using the first private key corresponding to the identity information of the coal transaction recipient, obtain the electronic evidence to be verified and upload it to the blockchain network; sign the second electronic evidence using the second private key corresponding to the identity information of the coal transaction sender, obtain the reference electronic evidence and upload it to the blockchain network; and bind the identity information of the coal transaction recipient with the first public key corresponding to the first private key to obtain the first binding information, bind the identity information of the coal transaction sender with the second public key corresponding to the second private key to obtain the second binding information, and upload the first binding information and the second binding information to the blockchain network;

[0092] The blockchain network 340 is used to receive the electronic evidence to be verified sent by the coal transaction receiver for the current coal transaction, obtain the reference electronic evidence uploaded by the coal transaction sender for the current coal transaction, use the reference electronic evidence to verify the electronic evidence to be verified, and in response to the verification result being successful, determine that the current coal transaction is a valid transaction and record the coal transfer information corresponding to the current coal transfer.

[0093] In one scenario, the key service center 330 includes a private key generation module and a public key generation module; wherein the private key generation module is used to pre-generate a first private key for a first information collection device of a coal transaction receiver, and to pre-generate a second private key for a second information collection device of a coal transaction sender; the public key generation module is used to pre-generate a second private key for the second information collection device of a coal transaction sender, and to generate a second public key corresponding to the second private key using an elliptic curve encryption algorithm.

[0094] In another case, the key service center 330 also includes: an information binding module, which is used to bind the identity information of the coal transaction recipient with the first public key, obtain the first binding information and issue a digital certificate, and bind the identity information of the coal transaction sender with the second public key, obtain the second binding information and issue a digital certificate.

[0095] It can be seen that the present invention uses blockchain technology to process the information in the coal operation process on the chain, thereby establishing transaction data with extremely high credibility between the coal transaction sender and the coal transaction receiver that is tamper-proof, can withstand inspection and audit. In addition, the solution provided by the present invention also simplifies the specific transaction process in coal transactions, and realizes the trusted transaction between the coal transaction sender and the coal transaction receiver in this cross-unit situation, which can not only reduce transaction costs and tracking and re-inspection costs, but also eliminate the concerns of both parties to the coal transaction about the untrue transaction data. Moreover, since both the coal transaction receiver and the coal transaction sender adopt an automated information collection method to obtain information, it can reduce physical harm to coal workers on site, and can also avoid the occurrence of under-recording and omission, thereby achieving the effect of reducing costs and increasing efficiency.
