Third embodiment

Fig. 7 is a flowchart of a weight processing method according to the present embodiment. The specific flow shown in fig. 7 will be described in detail below.

Step S301, a weight change signal on the cargo pallet is acquired.

In one embodiment, a weight change signal on the cargo pallet is obtained by a second load cell. I.e. by acquiring weight variations on the pallets, a weight variation signal is generated. Specifically, the weight value on the pallet at the initial time and the weight value on the pallet at the current time are acquired, and whether weight change occurs or not is judged through the change of the weight value between the time differences. Wherein, the initial moment refers to the moment when the door of the vending machine is opened. The current time refers to the time when the door of the vending machine is closed after being opened.

Step S302, acquiring a weight change value on each goods way.

By acquiring the weight change value on each goods channel, the weight change condition of the goods on a certain goods channel can be effectively monitored. For example, the weight on lane A decreases and the weight on lane B increases. And then the behavior of the user is judged according to the weight difference between the increase and the decrease, and whether the user places the commodity on the A commodity channel on the B commodity channel is judged, so that the condition of fee deduction errors is effectively avoided.

Step S303, obtaining the quotient of the weight change value and the unit weight of the commodity on each goods channel.

And dividing the weight change value corresponding to each goods channel with the unit weight of the goods on the goods channel to obtain a quotient after the division.

Step S304, judging whether the quotient is an integer.

And S305, if so, acquiring the total price of the commodity.

And when the quotient is an integer, acquiring the total price of the commodity purchased by the user according to the preset unit price and the quotient of the commodity.

Step S306, if not, obtaining the target weight change value on the goods tray corresponding to each goods channel.

Step S307, obtaining the type and quantity of the goods purchased by the user according to the target weight change value, the weight change value, and the unit weight of the goods on each goods channel.

As an embodiment, the difference is obtained by subtracting the target weight change value from the weight change value. And respectively dividing the difference value by the unit weight of the commodity on each goods channel, obtaining the quotient again, and when the quotient is an integer, indicating that the commodity corresponding to the difference value is the commodity on the goods channel. For example, when the first weighing sensor of one of the plurality of lanes is damaged, and the other weighing sensors are not damaged, the target weight change value is obtained through the second weighing sensor, and then secondary calculation is carried out, so that the monitoring on the commodity is effectively improved. The benefits of the merchant are further guaranteed.

And step S308, acquiring the total price of the commodities purchased by the user according to the category and the quantity.

In summary, the weighing device, the weight processing method and the vending machine provided by the invention have the advantages that the plurality of first weighing sensors are arranged between each goods channel and the goods tray, so that the weight change of each goods channel can be monitored in real time through the first weighing sensors, the goods information selected by a user can be followed in real time, the goods on each goods channel can be accurately detected, meanwhile, the goods channels are arranged on each goods tray, various similar goods can be placed, the diversity of the goods is improved, and great convenience is brought to the user in use. And through set up the second weighing sensor under the goods tray, can be so that when arbitrary one in a plurality of first weighing sensor damages, can also detect the weight change of commodity through second weighing sensor and the first weighing sensor that does not have the damage jointly, when further having ensured the interests of trade company, make the user can continue normal use.
