Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a block diagram illustrating a first embodiment of a management system for a steel slag grinding line according to the present invention. The steel slag grinding production line management system comprises: the system comprises a weighing device 10, a block chain 20, an industrial control software terminal 30 and a transportation notification device 40; the block chain 20 is respectively connected with the weighing device 10, the industrial control software end 30 and the transportation notification device 40, the weighing device 10 is connected with the transportation notification device 40, the industrial control software end 30 is used for monitoring the capacity of the storage tank, the transportation notification device 40 is used for determining a target powder transport vehicle needing to transport powder, and the weighing device 10 is used for weighing the steel slag raw material transport vehicle and the target powder transport vehicle.

It should be noted that the weighing device 10 is used for weighing a transportation vehicle, the industrial control software 30 is connected to the steel slag milling production line, and can perform start-stop control on the steel slag milling production line, the transportation notification device 40 can be a mobile terminal, such as a computer, a mobile phone, a tablet computer, and the like, the block chain 20 can be a public chain, a private chain, and an alliance chain, and the embodiment is not limited thereto.

It can be understood that the storage tank is used for storing powder, the powder is a product obtained after steel slag is processed by a production line, and the steel slag grinding production line comprises 4 main steps of blanking, grinding, powder discharging and the like.

Further, the weighing device 10 is configured to obtain an entry weight and an exit weight of the steel slag raw material transport vehicle, determine raw material weight information according to the entry weight and the exit weight, obtain encrypted weight information according to the raw material weight information, and upload the encrypted weight information to the block chain 20.

It should be understood that the weighing device 10 includes a floor scale, and a vehicle identification device for acquiring the entrance weight of the steel slag raw material transportation vehicle when the steel slag raw material transportation vehicle transports the raw material into the production line field, and the vehicle identification device is used for identifying according to vehicle characteristics, such as a license plate number, which can be a unique identifier of the transportation vehicle. After the steel slag raw material is unloaded to the production line by the transport vehicle, the departure weight of the transport vehicle can be obtained through the weighing device 10, so that the quality of the steel slag raw material conveyed by the transport vehicle, namely the raw material weight information, can be obtained according to the departure weight and the entrance weight of the transport vehicle. For example: the entering weight of the steel slag raw material transport vehicle with the vehicle number of AD76839 is 20 tons, the leaving weight of the transport vehicle is 5 tons after the transport vehicle is unloaded and leaves, and the weight of the raw material transported by the transport vehicle with the vehicle number of AD76839 is 15 tons.

The raw material weight information may include the weight of the raw material, the license plate number of the vehicle transporting the batch of raw material, the transportation time, and the like, and the embodiment is not limited thereto. In order to make the raw material weight information more secure and not tampered, the weighing apparatus 10 encrypts the raw material weight information to obtain encrypted weight information, and then sends the encrypted weight information to the block chain 20, and the encryption method may use a symmetric encryption algorithm or an asymmetric encryption algorithm, which is not limited in this embodiment.

Further, the block chain 20 is configured to decrypt the received encrypted weight information to obtain the raw material weight information, determine a raw material cumulative weight according to the raw material weight information, and send a machine start request to the industrial control software terminal 30 when the raw material cumulative weight is greater than a preset weight.

It will be appreciated that the weighing apparatus 10 and the blockchain 20 predetermine a preset key, with which the weighing apparatus 10 is encrypted and with which the blockchain is decrypted.

It should be noted that after a complete grinding production is performed on the production line, the steel slag raw material on the production line is consumed, and at this time, the quality of the raw material on the production line is zero. After the production line finishes one-time milling production, the block chain obtains the weight of steel slag raw materials accumulated on the production line according to the encrypted weight information uploaded by the weighing device 10, the weighing device 10 sends the encrypted weight information of a plurality of raw material transport vehicles to the block chain 20, and the block chain 20 obtains the accumulated raw material weight of the production line according to the encrypted weight information. When the accumulated weight of the raw materials exceeds the preset weight, the production line is indicated to reach the opening weight condition, and the production can be started. For example: the preset weight is 100 tons, the weight of the raw materials transported by the first vehicle is 30 tons, the weight of the raw materials transported by the second vehicle is 35 tons, and the weight of the raw materials transported by the third vehicle is 40 tons, at this moment, the accumulated weight of the raw materials is 105 tons, and the accumulated weight is larger than the preset weight, so that the production line can be opened for powder production.

In a specific implementation, the blockchain 20 is preset with a machine start/stop intelligent contract (Smart contract), which is a computer protocol intended to propagate, verify or execute contracts in an information-based manner. Smart contracts allow trusted transactions, which are traceable and irreversible, to be conducted without a third party. In this embodiment, the excitation condition of the machine start-stop intelligent contract is that the accumulated weight of the raw material is greater than the preset weight, when the accumulated weight of the raw material is greater than the preset weight, the machine start-stop intelligent contract calls the encapsulated device start-stop control interface, the device start-stop control interface is an external control interface provided by the industrial control software end 30, and the process of calling the start-stop control interface by the machine start-stop intelligent contract is actually that the intelligent contract communicates with the start-stop control interface, that is, a preset machine start-up request is sent. Or the start-stop intelligent contract sends a machine start request to an information notification interface of the industrial control software end 30, so that the industrial control software end 30 notifies a manager to start the production line.

It should be noted that the machine start request may include the raw material accumulated weight information, which is convenient for the manager to check the raw material weight information, and is convenient for the industrial control software terminal 30 to perform subsequent operations according to the raw material accumulated weight information.

Further, the industrial control software terminal is configured to control a production line machine to start after receiving the start request, determine capacity ratio information of the storage tank after the production line machine stops, obtain encrypted ratio information according to the capacity ratio information, and send the encrypted ratio information to the block chain.

It can be understood that, after the industrial control software end 30 controls the production line to start and complete production, that is, after all steel slag raw materials are completely processed, the production line sends the produced powder into the storage tank to be stored, the total mass of the raw materials is obtained according to the cumulative weight information of the raw materials produced this time, the volume ratio of the powder produced this time in the storage tank is determined according to the historical raw material density, the historical powder yield and the volume of the storage tank, and the calculation formula is as follows:

wherein M is_rThe weight of the raw materials in one production flow is r is the powder yield of the ground raw materials, rho is the density of the steel slag, and V is_mIs the storage tank volume.

The industrial control software terminal 30 generates capacity ratio information according to the capacity ratio of the current production, and the capacity ratio information may include information such as the capacity ratio of the current production and the time of the current production. And encrypts the capacity fraction information to obtain encrypted fraction information and sends it to the blockchain 20.

Further, the block chain 20 is further configured to obtain a capacity cumulative ratio according to the encrypted ratio information, determine volume information of the powder in the storage tank according to the capacity cumulative ratio when the capacity cumulative ratio is greater than a preset ratio, obtain encrypted volume information according to the volume information, and send the encrypted volume information to the transportation notification device 40.

It is understood that the blockchain 20 decrypts the encrypted proportion information to obtain the capacity proportion information, and obtains the capacity cumulative proportion after a plurality of production lines, and when the capacity cumulative proportion exceeds the preset proportion, it indicates that the storage of the storage tank is close to the upper limit of the capacity, and then the powder in the storage tank needs to be transported and transferred. For example: the preset ratio is 80%, the first production capacity ratio is 30%, the second production capacity ratio is 20%, and the third production capacity ratio is 35%, then the cumulative capacity ratio is 85%, and exceeds the preset ratio, and then the powder in the storage tank needs to be transferred. The block chain 20 determines the volume information of the powder through the accumulated ratio information, and the volume information comprises the powder volume in the storage tank.

It should be noted that the block chain 20 includes a preset intelligent contract for powder transportation, and when the capacity occupation ratio in the storage tank exceeds the preset occupation ratio, the intelligent contract for powder transportation is triggered, the information on the volume of the powder is encrypted to obtain encrypted volume information, and the encrypted volume information is sent to the transportation notification device 40.

Further, the transportation notification device 40 is configured to determine vehicle information of the target powder transportation vehicle according to the encrypted volume information, determine encrypted vehicle information according to the vehicle information, and send the encrypted vehicle information to the weighing device.

It should be noted that, after receiving the encrypted volume information, the transportation notification device 40 decrypts the encrypted volume information to obtain the volume information of the powder, and meanwhile, the transportation notification device 40 determines the number of powder transport vehicles according to the volume information, where the number calculation formula is:

wherein N is the number of powder transport vehicles, V_pAmount of powder to be transported in the slag yard, V_iThe capacity of each transport vehicle.

It is understood that the transportation notifying apparatus 40 selects the target powder transporting vehicles that are free according to the required number of the powder transporting vehicles, acquires the vehicle information of the target powder transporting vehicles, and notifies the transportation personnel to drive the target powder transporting vehicles to transport the powder.

It can be appreciated that the transportation notice apparatus 40 encrypts the vehicle information to obtain encrypted vehicle information, and transmits the encrypted vehicle information to the weighing apparatus 10.

Further, the weighing device 10 is further configured to obtain the powder transportation weight of the target powder transportation vehicle according to the encrypted vehicle information, generate powder weight information associated with time according to the powder transportation weight, obtain encrypted time weight information according to the powder weight information associated with time, and send the encrypted time weight information to the block chain 20.

It should be noted that the weighing device 10 decrypts the encrypted vehicle information to obtain the vehicle information for transporting the powder, and the vehicle information may include license plate information for identifying different transport vehicles, and it may also be determined whether the vehicle is used for raw material transportation or powder transportation according to the vehicle information.

It can be understood that the weighing device 40 determines the powder quality transported by each target powder transport vehicle according to the weight difference of the target powder transport entering and exiting from the field, and stamps the weight information of the powder quality of each target powder transport vehicle, so as to count the transport time, thereby obtaining the powder weight information associated with the time, and encrypts the powder weight information associated with the time to obtain the encrypted time weight information, and sends the encrypted time weight information to the block chain 20. For example: a certain target powder transport vehicle transports 30 tons of powder at 15 points 32 of 5, 10 and 10 months in 2021, and the weighing device 40 stamps the weight information of the powder with a time stamp of 32 points at 15 points of 10 days in 5 and 10 months in 2021.

Further, the block chain 20 is further configured to obtain the time-related powder weight information according to the encrypted time weight information, and determine a powder yield according to the time-related powder weight information and the raw material accumulated weight, so as to achieve intelligent management of the steel slag grinding production line.

It should be noted that, the block chain 20 decrypts the encrypted time weight information to obtain the powder weight information associated with the time, determines the total mass of the powder transported by all target powder transport vehicles in the transportation, and obtains the total mass of all raw materials used for producing the powder, where the total mass is the sum of the accumulated weights of the raw materials for multiple times, and obtains the powder yield according to the total mass of the raw materials and the total mass of the powder, and the calculation formula is as follows:

wherein r is the powder yield, the number of times of the complete production flow of the N production line, and M_rThe weight of the raw materials used in one production process is the accumulated value of the quantity of the raw materials triggering the intelligent contract of starting and stopping the machine, M_pThe powder discharge amount in one production flow is the sum of the powder weights of all target powder transport vehicles after all the powder in the storage tank is transported.

It can be understood that the powder output rate can be used for correcting the powder output rate when the storage tank capacity ratio is calculated, and more accurate management is achieved.

In this embodiment, the system includes: the system comprises weighing equipment, a block chain, an industrial control software end and transportation notification equipment; the weighing device is used for weighing a transport vehicle for transporting steel slag raw materials and powder, the block chain counts the weighed weight to enable an industrial control software end to control the start and stop of a steel slag grinding production line, the proportion of the produced powder in a storage tank is counted, when the proportion exceeds the preset proportion, the transport notification device notifies a transport worker to drive the transport vehicle to operate the powder, and finally, the powder yield is counted according to the weight of the powder and the weight of the steel slag, so that the intelligent management of a production line is realized.

An embodiment of the present invention provides a method for managing a steel slag milling production line, and referring to fig. 9, fig. 9 is a schematic flow diagram of a first embodiment of the method for managing a steel slag milling production line according to the present invention.

In this embodiment, the management method of the steel slag grinding production line includes the following steps:

step S10: the weighing device obtains the entering weight and the leaving weight of the steel slag raw material transport vehicle, determines raw material weight information according to the entering weight and the leaving weight, obtains encrypted weight information according to the raw material weight information, and uploads the encrypted weight information to the block chain.

It can be understood that the storage tank is used for storing powder, the powder is a product obtained after steel slag is processed by a production line, and the steel slag grinding production line comprises 4 main steps of blanking, grinding, powder discharging and the like.

It should be understood that the weighing device comprises a floor scale and a vehicle identification device, when the steel slag raw material transport vehicle transports the raw material into the production line field, the entering weight of the steel slag raw material transport vehicle is obtained, and the vehicle identification device is used for identifying according to vehicle characteristics, such as a license plate number, wherein the license plate number can be a unique identifier of the transport vehicle. After the steel slag raw material is unloaded to the production line by the transport vehicle, the departure weight of the transport vehicle can be obtained through the weighing device, so that the quality of the steel slag raw material conveyed by the transport vehicle, namely the raw material weight information, can be obtained according to the departure weight and the entry weight of the transport vehicle. For example: the steel slag raw material transport vehicle with the vehicle license number AD76839 has an entrance weight of 20 tons, and after the transport vehicle is unloaded and discharged, the discharge weight of the transport vehicle is 5 tons, so that the weight of the raw materials transported by the transport vehicle with the vehicle license number AD76839 is 15 tons.

The raw material weight information may include the weight of the raw material, the license plate number of the vehicle transporting the batch of raw material, the transportation time, and the like, and the embodiment is not limited thereto. In order to make the raw material weight information safer and not tampered, the weighing device encrypts the raw material weight information to obtain encrypted weight information, and then sends the encrypted weight information to the block chain, and the encryption method may use a symmetric encryption algorithm or an asymmetric encryption algorithm, which is not limited in this embodiment.

In order to ensure the safety of the data transmitted from the weighing device to the blockchain, step S10 further includes: the weighing module acquires the entrance weight and the exit weight of the steel slag raw material transport vehicle; the weighing calculation module determines raw material weight information according to the entrance weight and the exit weight; and the weighing encryption module obtains encrypted weight information by carrying out private key signature on the raw material weight information and uploads the encrypted weight information to the block chain.

In a specific implementation, the weighing module may be a floor scale with a specification of 3 × 9 meters, which can weigh a train weight within 100 tons, or may be changed into a floor scale with another specification according to a difference of the transportation quality, which is not limited in this embodiment.

It should be noted that the weighing calculation module may be a terminal device with calculation function, such as a computer, etc., and when the entering weight and the leaving weight of the same raw material transportation vehicle are determined, the conveying quality of the raw material, i.e. the raw material weight information, is obtained by calculating the quality difference.

It can be understood that the encryption uses an asymmetric algorithm, the weighing encryption module and the block chain jointly determine a pair of a public key and a private key, the weighing encryption module encrypts the raw material weight information through a private key signature to obtain encrypted weight information, and then the encrypted weight information is sent to the block chain.

It should be noted that, by obtaining the entry weight and the exit weight of the raw material transport vehicle, determining raw material weight information according to the entry weight and the exit weight, obtaining encrypted weight information by signing the raw material weight information with a private key, and uploading the encrypted weight information to the block chain, the raw material weight of each transport vehicle is accurately weighed, and the weight information is encrypted and transmitted, so that the security of data transmission is ensured.

Step S20: and the block chain decrypts the received encrypted weight information to obtain the raw material weight information, determines the accumulated weight of the raw material according to the raw material weight information, and sends a machine starting request to the industrial control software end when the accumulated weight of the raw material is greater than the preset weight.

It will be appreciated that the weighing apparatus and the blockchain predetermine a preset key, the weighing apparatus being encrypted using the preset key, and the blockchain being decrypted using the preset key.

It should be noted that after a complete grinding production is performed on the production line, the steel slag raw material on the production line is consumed, and at this time, the quality of the raw material on the production line is zero. After the production line finishes one-time grinding production, the block chain obtains the weight of the steel slag raw materials accumulated on the production line according to the encrypted weight information uploaded by the weighing equipment, the weighing equipment sends the encrypted weight information of the raw material transport vehicles to the block chain, and the block chain obtains the accumulated weight of the raw materials accumulated on the production line according to the encrypted weight information. When the accumulated weight of the raw materials exceeds the preset weight, the production line is indicated to reach the opening weight condition, and the production can be started. For example: the preset weight is 100 tons, the weight of the raw materials transported by the first vehicle is 30 tons, the weight of the raw materials transported by the second vehicle is 35 tons, and the weight of the raw materials transported by the third vehicle is 40 tons, at this moment, the accumulated weight of the raw materials is 105 tons, and the accumulated weight is larger than the preset weight, so that the production line can be started to produce powder.

In a specific implementation, a machine start-stop intelligent contract is preset in a blockchain, and the intelligent contract (Smart contract) is a computer protocol aiming at propagating, verifying or executing the contract in an information-based manner. Smart contracts allow trusted transactions, which are traceable and irreversible, to be conducted without a third party. In this embodiment, the excitation condition of the machine start-stop intelligent contract is that the accumulated weight of the raw materials is greater than the preset weight, when the accumulated weight of the raw materials is greater than the preset weight, the machine start-stop intelligent contract calls an encapsulated equipment start-stop control interface, the equipment start-stop control interface is an external control interface provided by an industrial control software end, and the process of calling the start-stop control interface by the machine start-stop intelligent contract is actually communication between the intelligent contract and the start-stop control interface, that is, a preset machine start request is sent. Or the intelligent starting and stopping contract sends a machine starting request to an information notification interface of the industrial control software end, so that the industrial control software end notifies a manager to start the production line.

It should be noted that the machine start request may include the raw material accumulated weight information, which is convenient for the manager to check the weight information of the raw material, and is convenient for the industrial control software end to perform the subsequent operation according to the raw material accumulated weight information.

Step S30: and the industrial control software terminal controls the production line machine to start after receiving the starting request, determines the capacity ratio information of the storage tank after the production line machine stops, obtains encrypted ratio information according to the capacity ratio information, and sends the encrypted ratio information to the block chain.

wherein, M_rThe weight of the raw materials in one production flow, r is the powder yield of the ground raw materials, rho is the density of the steel slag, and V is_mIs the storage tank volume.

It can be understood that the blockchain decrypts the encrypted proportion information to obtain the capacity proportion information, and obtains the capacity accumulated proportion after a plurality of production lines are produced, when the capacity accumulated proportion exceeds the preset proportion, the storage of the storage tank is close to the upper limit of the capacity, and the powder in the storage tank needs to be transported and transferred. For example: the preset ratio is 80%, the first production capacity ratio is 30%, the second production capacity ratio is 20%, and the third production capacity ratio is 35%, then the cumulative capacity ratio is 85%, and if the preset ratio is exceeded, the powder in the storage tank needs to be transferred. And the block chain determines the volume information of the powder through the accumulated proportion information, wherein the volume information comprises the volume of the powder in the storage tank.

It should be noted that the block chain includes a preset intelligent contract for powder transportation, and when the capacity occupation ratio in the storage tank exceeds the preset occupation ratio, the intelligent contract for powder transportation is triggered, the powder volume information is encrypted to obtain encrypted volume information, and the encrypted volume information is sent to the transportation notification device.

Step S60: the weighing equipment acquires the powder transportation weight of the target powder transportation vehicle according to the encrypted vehicle information, generates powder weight information associated with time according to the powder transportation weight, acquires encrypted time weight information according to the powder weight information associated with the time, and sends the encrypted time weight information to the block chain.

It should be noted that the weighing device decrypts the encrypted vehicle information to obtain vehicle information for transporting the powder, where the vehicle information may include license plate information for identifying different transport vehicles, and it may also be determined whether the vehicle is used for raw material transportation or powder transportation according to the vehicle information.

For example: a certain target powder transport vehicle transports 30 tons of powder at 15 points 32 of 5, 10 and 10 months in 2021, and the weighing equipment stamps the weight information of the powder with a time stamp of 15 points 32 of 10 days in 5 and 10 months in 2021.

Step S70: and the block chain obtains the powder weight information associated with time according to the encrypted time weight information, and determines the powder yield according to the powder weight information associated with time and the accumulated weight of the raw materials so as to realize intelligent management of the steel slag grinding production line.

It should be noted that, the block chain decrypts the encrypted time weight information to obtain the powder weight information associated with time, determines the total mass of the powder transported by all target powder transport vehicles in the transportation, and obtains the total mass of all raw materials used for producing the powder, where the total mass is the sum of the cumulative weights of the raw materials for multiple times, and obtains the powder yield according to the total mass of the raw materials and the total mass of the powder, and the calculation formula is as follows:

wherein r is the powder yield, the number of times of the complete production flow of the N production line, M_rThe weight of the raw material used in one production process is the accumulated value of the quantity of the raw material triggering the intelligent contract of starting and stopping the machine, M_pThe powder output in one production flow is the value of all target powder when all powder in the storage tank is transportedThe sum of the weight of the powder in the transport vehicle.
