In the embodiment of the present invention, the item management system may obtain a purchase request for purchasing a specified item, where the purchase request carries user information of a target user.

In one embodiment, the item management system may obtain a purchase request sent by a user terminal for purchasing a specified item, where the purchase request carries user information of a target user. In certain embodiments, the specified article includes, but is not limited to, tobacco. In some embodiments, the user information includes, but is not limited to, a user identifier, and in an example, the user identifier may be any one or more of an identification number, a telephone number, a name, and the like, and the embodiments of the present invention are not limited in particular.

S202: and inquiring whether historical invoice information of the specified article corresponding to the user information exists in a block chain corresponding to the block chain network.

In the embodiment of the present invention, the article management system may query whether historical invoice information of the specified article corresponding to the user information exists in a blockchain corresponding to a blockchain network.

In one embodiment, the user information includes a user identifier, and when the article management system obtains a purchase request for purchasing a specified article, it may be queried whether historical invoice information of the specified article corresponding to the user identifier carried in the purchase request exists in a blockchain corresponding to a blockchain network.

In an example, assuming that the user identifier is an identity card number, and the specified article is tobacco, when the article management system obtains a purchase request sent by the user terminal and used for instructing to purchase tobacco, the article management system may query whether historical invoice information of tobacco corresponding to the identity card number carried in the purchase request exists in a block chain corresponding to a block chain network.

Whether historical invoice information of the specified items corresponding to the user identification carried in the purchase request exists in the blockchain corresponding to the block chain network is inquired, and the method is helpful for confirming the number of the specified items purchased by the target user corresponding to the user identification at present.

S203: and if the inquiry result is yes, determining the historical purchase quantity of the specified item purchased by the target user within a preset time range according to the historical invoice information.

In the embodiment of the present invention, if the article management system queries that historical invoice information of the specified article corresponding to the user information exists in the blockchain corresponding to the blockchain network, the article management system may determine, according to the historical invoice information, the historical purchase quantity of the specified article purchased by the target user within a preset time range.

In one embodiment, the historical invoice information includes information such as user identification, purchase quantity of the specified item, consumption tax, consumption amount, etc., and the item management system may determine the historical purchase quantity of the specified item purchased by the target user within a preset time range according to the historical invoice information.

In one example, assuming that the article management system queries that there are 3 pieces of historical invoice information of tobacco corresponding to the user identifier of the target user in the blockchain corresponding to the blockchain network, if the number of pieces of tobacco purchased by the target user in the 3 pieces of historical invoice information is 2, and 3 respectively and is within a period of 1 month, it may be determined that the historical purchase number of the tobacco purchased by the target user within 1 month is 7 according to the 3 pieces of historical invoice information.

The method is used for determining the historical purchase quantity of the specified items purchased by the target user within the preset time range, and is helpful for confirming the quantity and the tax of the specified items which can be purchased by the target user within the preset time range so as to realize the limit of purchasing the specified items.

S204: and determining the purchase quantity and the consumption tax of the target user for currently purchasing the specified item according to the user information and the historical purchase quantity.

In this embodiment of the present invention, the item management system may determine the purchase amount and the consumption tax of the target user for currently purchasing the specified item according to the user information and the historical purchase amount.

In one embodiment, after determining the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the user information and the historical purchase quantity, the item management system may determine a consumption amount corresponding to the purchase quantity of the specified item currently purchased by the target user, and send an invoicing request to the blockchain network, where the invoicing request carries the purchase quantity, the consumption tax and the consumption amount of the specified item currently purchased by the target user, and the invoicing request is used to instruct the blockchain network to generate invoice information corresponding to the current purchase of the specified item according to the purchase quantity, the consumption tax and the consumption amount, and write the invoice information into the blockchain.

In one example, assuming that the current purchase quantity of tobacco for the target user is 2 packets, the consumption amount corresponding to the purchase of 2 packets of tobacco for the user is 44 yuan, and the consumption tax corresponding to the 2 packets of tobacco for the user is 10 yuan, the article management system may send an invoicing request to the blockchain network, where the invoicing request carries the current purchase quantity of tobacco for the target user, 2 packets, consumption tax 10 yuan, and consumption amount 44 yuan, and write the invoice information into the blockchain of the blockchain network.

The invoice information of the specific articles purchased by the user is made through the blockchain network, and the invoice information is written into the blockchain of the blockchain network, so that the subsequent article management system is facilitated to determine the historical purchase quantity of the specific articles purchased by the user by inquiring the historical invoice information of the specific articles purchased by the user on the blockchain.

In one embodiment, the user information includes a user age; when the item management system determines the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the user information and the historical purchase quantity, the upper limit of the purchase quantity of the target user in the preset time range can be determined according to the user age of the target user; and if the historical purchase quantity is smaller than the purchase quantity upper limit, determining the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the difference between the purchase quantity upper limit and the historical purchase quantity.

In one embodiment, the article management system is preset with a corresponding relationship between the age of the user and the upper limit of the purchase quantity of the purchased specified article, and the embodiment of the present invention does not specifically limit the corresponding relationship between the age of the user and the upper limit of the purchase quantity of the purchased specified article. In one example, the relationship between the user age preset in the article management system and the upper limit of the purchase quantity for purchasing the specified article is as follows: the upper limit of the tobacco purchase quantity of the users under 18 years old is 0, the upper limit of the tobacco purchase quantity of the users under 18 years old is 3 bags in one month, the upper limit of the tobacco purchase quantity of the users under 29-40 years old is 5 bags in one month, the upper limit of the tobacco purchase quantity of the users under 41-60 years old is 4 bags in one month, the upper limit of the tobacco purchase quantity of the users under 60-80 years old is 3 bags in one month, and the upper limit of the tobacco purchase quantity of the users over 80 years old is 2 bags in one month.

In one embodiment, the article management system is preset with the corresponding relationship among the age of the user, the purchase quantity and the consumption tax, and the embodiment of the invention does not specifically limit the corresponding relationship among the age of the user, the purchase quantity and the consumption tax. In one example, the correspondence relationship among the age, the purchase amount and the consumption tax of the user preset by the article management system may be: a user aged 18-28 purchases tobacco in a month at a rate of 10% of a tobacco price per package, a user aged 29-40 purchases tobacco in a month at a rate of 10% of a tobacco price per package, a user aged 41-60 purchases tobacco in a month at a rate of 5% of a tobacco price per package, a user aged 60-80 purchases tobacco in a month at a rate of 2% of a tobacco price per package, and a user aged 80 purchases tobacco in a month at a rate of 1% of a tobacco price per package.

In one example, assuming that the user age of the target user is 30 years and the preset time range is 1 month, the article management system may determine that the target user purchases 5 packs of tobacco within 1 month according to the user age of the target user being 30 years, may determine that the historical purchase amount of the target user purchases 3 packs of tobacco within 1 month is less than the purchase amount upper limit 5 packs of tobacco, may determine that the target user currently purchases 2 packs of tobacco according to a difference value of 5-3 ═ 2 packs between the purchase amount upper limit 5 packs and the historical purchase amount 3 packs, and may determine that the consumption tax is 20 × 10% — 2 packs if the price per pack is 20 elements and the consumption is 10% of the price per pack of tobacco.

In one embodiment, the purchase request also carries the purchase quantity; when determining the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the difference between the purchase quantity upper limit and the historical purchase quantity, the item management system may determine the difference between the purchase quantity upper limit and the historical purchase quantity, and determine whether the purchase quantity carried in the purchase request is greater than the difference, if the determination result is yes, the purchase quantity and the consumption tax of the specified item currently purchased by the target user may be determined according to the difference, and if the determination result is no, the purchase quantity and the consumption tax of the specified item currently purchased by the target user may be determined according to the purchase quantity carried in the purchase request.

In an embodiment, when determining the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the purchase quantity carried in the purchase request, the item management system may determine that the purchase quantity carried in the purchase request is the purchase quantity of the specified item currently purchased by the target user, and determine the consumption tax corresponding to the purchase quantity carried in the purchase request according to a preset corresponding relationship between the quantity and the consumption tax and a user age of the target user.

In one example, assume that the purchase quantity of tobacco carried in the purchase request is 1 pack, the historical purchase quantity in one month is 1 pack, and the upper limit of the purchase quantity in 1 month is 3 packs; the item management system may determine that the purchase amount upper limit 3 packages is different from the historical purchase amount 1 packages by 2 packages. Therefore, it may be determined that the purchase quantity 1 pack carried in the purchase request is smaller than the difference 2 pack, and it is determined that the purchase quantity of the target user currently purchasing tobacco is 1 pack according to the purchase quantity 1 pack carried in the purchase request, and if the price of 1 pack of tobacco is 20 yuan and the age of the target user is 30 years, the consumption tax may be determined to be 10% of the tobacco price, thereby determining that the consumption tax is 20 × 10% — 2 yuan.

In one embodiment, when determining the purchase quantity and the consumption tax of the specified item currently purchased by the target user according to the difference, the item management system may determine that the difference is the purchase quantity of the specified item currently purchased by the target user, and determine the consumption tax corresponding to the difference according to a preset corresponding relationship between the quantity and the consumption tax and the user age of the target user.

In one example, assume that the purchase quantity of tobacco carried in the purchase request is 3 bales, the historical purchase quantity in one month is 1 bale, and the upper limit of the purchase quantity in 1 month is 3 bales; the item management system may determine that the purchase amount upper limit 3 packages is different from the historical purchase amount 1 packages by 2 packages. Therefore, it can be determined that the purchase quantity 3 packets carried in the purchase request is greater than the difference 2 packets, and it is determined that the purchase quantity of the target user currently purchasing tobacco is 2 packets according to the difference 2 packets, and if the price of 1 packet of tobacco is 20 yuan and the age of the target user is 30 years, the consumption tax can be determined to be 10% of the tobacco price, so as to determine that the consumption tax is 2 × 20 × 10% — 4 yuan.

The method helps to limit the purchase of the specified items by the users at different ages by setting the purchase quantity and the consumption tax of the specified items purchased by the users at different ages.

In one embodiment, the article management system may determine, when the target user confirms payment of a corresponding consumption tax when it is determined that the historical purchase quantity of the target user within a preset time range is greater than or equal to the purchase quantity upper limit of the target user within the preset time range, an additional quantity and consumption tax at which the target user may purchase the specified article, and the target user cannot purchase the specified article within the preset time range beyond the additional quantity.

In one example, the correspondence relationship among the age, the purchase quantity and the consumption tax of the user, which is preset by the article management system, may also be: a user 18-28 years old purchases tobacco in a month with an amount exceeding the upper limit of the amount purchased, a royalty charge of 80% of the price per package of tobacco, and the target user purchases an additional amount of tobacco of 2 packages; a 29-40 year old user purchases tobacco in a month that exceeds the upper limit of the purchase amount by 90% of the price per package of tobacco, and the target user purchases an additional amount of tobacco of 4 packages; a user age of 41-60 may charge a consumption tax 60% of the price per pack of tobacco in a month that the amount of tobacco purchased by the user exceeds the upper limit of the amount purchased, and the target user purchases 3 packs of tobacco in additional amounts; the user aged 60-80 purchases 50% of the tobacco per package price with the amount of tobacco purchased exceeding the upper limit of the purchase amount in one month, and the target user purchases 2 packages of tobacco, the user aged 80 or older purchases 40% of the tobacco per package price with the amount of tobacco purchased exceeding the upper limit of the purchase amount in one month, and the target user purchases 1 package of tobacco.

The purchase of the specified items by the users is further limited by increasing the consumption tax and limiting the additional purchase quantity when the purchase quantity of the specified items by the users of different ages exceeds the upper limit of the purchase quantity.
