The quantity is judged whether there is a change in the goods, the weight of the goods taken away or returned, and the time point at which the goods are taken away or put back and the position of the corresponding tray 5 are recorded. When a certain item is taken away, the weight value data collected by the weight sensing device 4 below the tray 5 of the product becomes smaller, and when a certain item is put back, the item is placed under the tray 5 The weight value data collected by the weight sensing device 4 becomes large.

The data storage unit 71 is configured to store the item weight value of each item and the suspension bracket number corresponding to each item; the weight value updating unit 72 is configured to store and update the real-time weight value of all items on each suspension bracket. In the initial state, all the suspension brackets are full of goods, and the weight value updating unit 72 stores the total weight of all the goods on each suspension bracket. When the user removes a certain item from a suspension bracket or puts back a certain item onto a suspension bracket, a weight sensing device obtains the real-time weight sensing value of all the goods on the suspension bracket at this time, and the weight difference is calculated. The unit 73 calculates a weight difference between the real-time weight value and the real-time weight value of all the items on the suspension bracket existing in the weight value updating unit 72. The determining unit 74 is configured to determine the change of the pick-and-place information of the item according to the weight difference. When the weight difference is less than 0, it is determined that the goods are taken away; when the weight difference is less than 0, the tray matching unit 75 is configured to acquire the tray number corresponding to the weight sensor; the weight matching unit 76 is configured according to the The tray number matches the absolute value of the weight difference with the item weight value of each item on the tray, and determines the type and quantity of the item to be taken. For example, three types of goods X, Y, and Z are placed on three trays A, B, and C on the same shelf, and the weights of the corresponding items are 50 grams, 80 grams, and 100 grams, respectively. When a user removes two items from the tray B, the weight sensing device corresponding to the tray B acquires the real-time weight sensing value, and the weight difference calculating unit 73 calculates the difference between the real-time weight sensing value and the real-time weight value of the tray B. The value is 160 g, and the weight of the article corresponding to the tray B stored in the data storage unit 71 is 80 g in advance, and the weight matching unit 76 can calculate that the number of the articles taken is two. The data processing device 7 can record the position of the lighter weight and the lightening time, and can understand the shopping behavior of each user in real time, and the shopping behavior refers to when, where and what kind of goods are taken away, and then combined. User identification technology can confirm who and when and what kind of goods are taken away, so that each user's shopping record can be recorded in detail, and when the user leaves the shopping area, he can settle the user himself.
