The embodiment of the application provides an information processing method and device, which are used for improving information credibility. The following will describe in detail.
In order to better understand the information processing method and device provided by the embodiment of the present application, the network architecture of the embodiment of the present application is described below. Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the application. As shown in fig. 1, the network architecture may include a plurality of block link point devices (only 3 are shown schematically in fig. 1). The plurality of block link point devices can be connected through a network. The plurality of block chain node devices form a block chain, the plurality of block chain node devices are block nodes in the block chain respectively, and each block node corresponds to an identity code and is used for uniquely identifying the block chain link point device in the block chain. The block link point device may be provided with a display screen, i.e. may display information. A plurality of block link point devices may communicate with each other.
Referring to fig. 2, fig. 2 is a flow chart of an information processing method according to an embodiment of the application based on the network architecture shown in fig. 1. The information processing method is applied to block link point equipment. As shown in fig. 2, the information processing method may include the following steps.
201. A price change request carrying a material identification and a first price is received.
In this embodiment, after all material prices in the engineering project have been determined, a material price list may be determined, which may include a material identification and a material price. The material identifier may be a material name, or may be other information for uniquely identifying the material, which is not limited in this embodiment. A material cost table may be stored in the blockchain through a first blocknode in the blockchain. In the event that a change is desired to the price of a material in the material price list, the user may operate a second block node in the blockchain so that the second block node may send a price change request to the first block node carrying the material identification and the first price, after which the first block node receives the price change request from the second block node. The first price is that the material corresponding to the material identifier needs to be changed to the first price. The first block node is any block node in the blockchain. The second block node may be the first block node or any block node except the first block node in the blockchain.
202. Judging whether the price change of the material corresponding to the material identifier is reasonable or not according to the first price, and executing step 203 when judging that the price change of the material corresponding to the material identifier is reasonable.
In this embodiment, after receiving the price change request carrying the material identifier and the first price, it may be determined whether the price change of the material corresponding to the material identifier is reasonable according to the first price, and step 203 may be executed if it is determined that the price change of the material corresponding to the material identifier is reasonable. And when the condition that the price change of the material corresponding to the material identifier is unreasonable is judged, the price change request can be discarded, and in addition, prompt information for prompting the unreasonable price change can be sent to the second block node, so that the user can confirm the unreasonable price change.
In this embodiment, the price range may be obtained by first querying the current price of the material corresponding to the material identifier (i.e., the current transaction price on the network) from the network, then determining whether the first price is within the price range, and determining that the price change of the material corresponding to the material identifier is reasonable if the first price is determined to be within the price range. And under the condition that the first price is judged to be out of the price range, determining that the price change of the material corresponding to the material identifier is unreasonable. The minimum and maximum values in the price range are the current minimum and maximum prices, respectively, for the material identified corresponding to the material queried from the network. And judging whether the first price is in a price range or not, namely judging whether the first price is larger than or equal to the current lowest price and smaller than or equal to the current highest price or not. The rationality of price change can be determined according to the current selling price of the material, and the price change time can be different, and the corresponding price units can be different, so that the flexibility of determining the rationality of price change information can be improved.
In this embodiment, the material price list may also include acceptable material price ranges. Therefore, whether the first price is within the preset range or not can be judged, and the price change of the material corresponding to the material identifier is determined to be reasonable under the condition that the first price is within the preset range. And under the condition that the first price is judged to be out of the preset range, determining that the price change of the material corresponding to the material identifier is unreasonable. A range of acceptable material prices is within the preset range herein.
In this embodiment, the second price of the material corresponding to the material identifier with the storage time closest to the current time may be obtained first, that is, the current price of the material corresponding to the material identifier in the material price list may be obtained. And then judging whether the difference between the first price and the second price is smaller than a threshold value, and determining that the price change of the material corresponding to the material identifier is reasonable under the condition that the difference between the first price and the second price is smaller than the threshold value. And under the condition that the difference between the first price and the second price is larger than or equal to the threshold value, determining that the price change of the material corresponding to the material mark is unreasonable. That is, the rationality of the price change can be determined by the fluctuation of the material price, and the price change is considered unreasonable when the fluctuation is large, and the price change is considered reasonable when the fluctuation is small.
203. And changing the price of the material corresponding to the material identifier to a first price.
In this embodiment, when it is determined that the price of the material corresponding to the material identifier is changed reasonably, the price of the material corresponding to the material identifier may be changed to the first price, that is, the price of the material corresponding to the material identifier is changed from the current price in the material price list to the first price.
The first block node and the second block node are block link point devices in the network architecture.
In the information processing method described in fig. 2, a price change request carrying a material identifier and a first price is received, and when it is determined that the price change of a material corresponding to the material identifier is reasonable according to the first price, the price of the material corresponding to the material identifier is changed to the first price, and therefore, the price of the material is changed only when it is determined that the price change is reasonable, and therefore, the information reliability can be improved.
Referring to fig. 3, fig. 3 is a flow chart of another information processing method according to an embodiment of the application based on the network architecture shown in fig. 1. The information processing method is applied to block link point equipment. As shown in fig. 3, the information processing method may include the following steps.
301. A price change request carrying a material identification and a first price is received.
In this embodiment, after all material prices in the engineering project have been determined, a material price list may be determined, which may include a material identification and a material price. The material identifier may be a material name, or may be other information for uniquely identifying the material, which is not limited in this embodiment. A material cost table may be stored in the blockchain through a first blocknode in the blockchain. In the event that a change is desired to the price of a material in the material price list, the user may operate a second block node in the blockchain so that the second block node may send a price change request to the first block node carrying the material identification and the first price, after which the first block node receives the price change request from the second block node. The first price is that the material corresponding to the material identifier needs to be changed to the first price. The first block node is any block node in the blockchain. The second block node may be the first block node or any block node except the first block node in the blockchain.
302. If it is determined that the user corresponding to the identification code has the authority to change the engineering price corresponding to the engineering identifier, step 303 is executed.
In this embodiment, the price change request may further carry an identity code and an engineering identifier, where the engineering corresponding to the engineering identifier is the engineering where the material corresponding to the material identifier is located. Therefore, after receiving the price change request, it may be determined whether the user corresponding to the identity code has the authority to change the engineering price corresponding to the engineering identifier, and if it is determined that the user corresponding to the identity code has the authority to change the engineering price corresponding to the engineering identifier, step 303 is executed. When it is determined that the user corresponding to the identity code does not have the authority to change the engineering price corresponding to the engineering identifier, the price change request may be discarded, and in addition, a prompt message for prompting that the user does not have the authority to change the engineering corresponding to the engineering identifier may be sent to the second block node corresponding to the identity code.
In this embodiment, different users of the same project may have the authority to change different information in the project, so that it may also be determined whether the user corresponding to the identity code has the authority to change the price of the material in the project corresponding to the project identifier, and if it is determined that the user corresponding to the identity code has the authority to change the price of the material in the project corresponding to the project identifier, step 303 is executed.
In this embodiment, it may be first determined whether the identity code belongs to the identity code of the block node in the blockchain, i.e. whether the second block node is a block node in the blockchain, i.e. identity authentication is performed. In the event that a determination is made that the identity code belongs to the identity code of a block node in the blockchain, indicating that the second block node is a block node in the blockchain, step 302 is performed. In the event that the identity code is determined not to belong to the identity code of a block node in the blockchain, indicating that the second block node is not a block node in the blockchain, the price change request may be discarded. Wherein users may be in one-to-one correspondence with block nodes in the blockchain.
303. Judging whether the price change of the material corresponding to the material identifier is reasonable or not according to the first price, and executing step 304 when judging that the price change of the material corresponding to the material identifier is reasonable.
In this embodiment, after receiving the price change request, or when it is determined that the user corresponding to the identification code has the authority to change the engineering price corresponding to the engineering identifier, it may be determined whether the price change of the material corresponding to the material identifier is reasonable according to the first price, and if it is determined that the price change of the material corresponding to the material identifier is reasonable, step 304 may be performed. And when the condition that the price change of the material corresponding to the material identifier is unreasonable is judged, the price change request can be discarded, and in addition, prompt information for prompting the unreasonable price change can be sent to the second block node, so that the user can confirm the unreasonable price change.
In this embodiment, the price range may be obtained by first querying the current price of the material corresponding to the material identifier (i.e., the current transaction price on the network) from the network, then determining whether the first price is within the price range, and determining that the price change of the material corresponding to the material identifier is reasonable if the first price is determined to be within the price range. And under the condition that the first price is judged to be out of the price range, determining that the price change of the material corresponding to the material identifier is unreasonable. The minimum and maximum values in the price range are the current minimum and maximum prices, respectively, for the material that is queried from the network to identify the corresponding material. And judging whether the first price is in a price range or not, namely judging whether the first price is larger than or equal to the current lowest price and smaller than or equal to the current highest price or not. The rationality of price change can be determined according to the current selling price of the material, and the price change time is different, and the corresponding price range is possibly different, so that the flexibility of determining the rationality of price change information can be improved.
In this embodiment, the material price list may also include acceptable material price ranges. Therefore, whether the first price is within the preset range or not can be judged, and the price change of the material corresponding to the material identifier is determined to be reasonable under the condition that the first price is within the preset range. And under the condition that the first price is judged to be out of the preset range, determining that the price change of the material corresponding to the material identifier is unreasonable. The preset range here is an acceptable range of material prices.
In this embodiment, the second price of the material corresponding to the material identifier with the storage time closest to the current time may be obtained first, that is, the current price of the material corresponding to the material identifier in the material price list may be obtained. And then judging whether the difference between the first price and the second price is smaller than a threshold value, and determining that the price change of the material corresponding to the material identifier is reasonable under the condition that the difference between the first price and the second price is smaller than the threshold value. And under the condition that the difference between the first price and the second price is larger than or equal to the threshold value, determining that the price change of the material corresponding to the material mark is unreasonable. That is, the rationality of the price change can be determined by the fluctuation of the material price, and the price change is considered unreasonable when the fluctuation is large, and the price change is considered reasonable when the fluctuation is small.
304. And changing the price of the material corresponding to the material identifier to a first price.
In this embodiment, when it is determined that the price of the material corresponding to the material identifier is changed reasonably, the price of the material corresponding to the material identifier may be changed to the first price, that is, the price of the material corresponding to the material identifier is changed from the current price in the material price list to the first price.
305. The first price of the material corresponding to the changed material identification is stored.
In this embodiment, after changing the price of the material corresponding to the material identifier to the first price, the first price of the material corresponding to the changed material identifier may be stored, that is, the changed material price list may be stored. In addition, the time of change may be stored, along with a second price for the material corresponding to the material identification before change, i.e., a material price list before change. In addition, identity codes may also be stored. The identity code and change time may record which user made the change at what time. So that calls can be made later.
In this embodiment, after the changed material price table is determined, an approval request for approving the material price table may be sent to the third block node, and after the third block node receives the approval request from the first block node, approval or ticket signing may be performed on the material price table according to the corresponding authority. The first block node sends an approval request for approving the material price list to the third block node, or the first block node automatically sends the approval request to the third block node, or a user operates the first block node so that the first block node sends the approval request to the third block node. The third block node is any block node in the block chain corresponding to the user with authority to examine or approve the material price list.
The first block node and the second block node are block link point devices in the network architecture.
For example, in a specific project process, a material price is greatly increased, after an engineer of the project finds that the material price is changed, the engineer of the project feels that the material price can greatly influence the progress of a subsequent project, under the condition that the engineering has the material price change authority of the project, a material price change file is put forward in a blockchain system where the project is located, the project is subsequently transferred to a project manager for checking, the project manager can selectively adjust after seeing the material price change file, if the project manager does not have the issue authority, the project manager continues to transfer to links of personnel (such as a general manager, a president and the like) with the issue authority, in addition, in each transfer link of the project, the identity authentication of an operator is required before the operation, and the project manager can have authority to perform the next operation after the identity authentication.
In the information processing method described in fig. 3, the price of the material is changed only if it is determined that the price change is reasonable, and therefore, the information reliability can be improved.
Referring to fig. 4, fig. 4 is a schematic diagram of an information processing apparatus according to an embodiment of the present application. The information processing device is a block chain link point device. As shown in fig. 4, the information processing apparatus may include:
a receiving unit 401 for receiving a price change request carrying a material identifier and a first price;
