Description

Combined weighing platform

Technical Field

The utility model relates to novel trade settlement equipment, in particular to a combined weighing platform.

Background

An intelligent dining platform scale has been released in intelligent dining room, and it includes a weighing platform that can trade the settlement, and the weighing platform includes weighing platform tray and tray weighing sensor. During the in-service use, the dining room will be prepared a meal and place in on the weighing platform tray, and the prepared meal can be rice, also can be various dishes, and the personnel of having dinner uses clip or ladle to add the meal to the dinner plate of oneself, and the reduction of weight in the weighing platform tray is measured to tray weighing sensor, confirms the meal volume that the personnel of having dinner obtained. That is, assuming that the weighing of the tray load cell is N1 before the diner eats, and the weighing of the tray load cell is N2 after the diner eats, the weight of the meal obtained by the diner is N1-N2, and then the meal is paid by the diner at the weighing platform by multiplying the unit price, and the intelligent dining-table scale automatically settles to deduct the balance in the account of the diner.

This intelligence dining table scale has significantly reduced the demand quantity to the dining room personnel, also can realize eating to a certain extent simultaneously how much take the demand, but it has following technical problem: when a restaurant places a meal to a weighing platform tray, the weight of the meal is faced to all diners, so the weight of the meal for the first time is heavier, for example, the weight of the meal for the first time is 10-20 kg, the measurement range of the tray weighing sensor is required to be larger, the larger measurement range is inevitably free of higher measurement precision, the meal taking amount of the diners for each time is not large, often, only dozens of grams to hundreds of grams, the tray weighing sensor with the larger measurement range cannot accurately weigh the meal taking amount of the diners for each time, when facing the meal for lower unit price, for example, rice, the influence is not large, but when facing the meal for higher unit price, a larger fee deduction error can be caused finally.
