As a further limitation of the present technical solution, the weighing sensor is a two-hole cantilever beam type.
As a further limitation of the technical scheme, the main metal support is hyperbolic, a clamping groove is formed in the main metal support, and the weighing sensor is fixedly connected in the clamping groove.
As a further limitation of the technical scheme, the plane supporting point of the main metal bracket comprises a groove.
As the further restriction of the technical scheme, a silica gel gasket is arranged in the groove to improve the stability.
As a further limitation of the technical solution, pins 11 to 16 of the control calculation unit are respectively and sequentially electrically connected to pins 1 to 5 of the radio frequency module, pins 21 to 22 of the control calculation unit are respectively and sequentially electrically connected to pins 1 to 2 of the weighing sensor, pins 96 to 97 of the control calculation unit are respectively and sequentially electrically connected to pins 1 to 2 of the WIFI module, and an LCD interface of the control calculation unit is respectively and sequentially electrically connected to pins 1 to 24 of the liquid crystal display.
Compared with the prior art, the utility model discloses an advantage is with positive effect:
(1) compared with the traditional mode of pricing according to portions and taking meals by self-service, the device can not quantitatively evaluate the meal consumption of a diner and is easy to cause the situations of food waste and excessive intake, the device can quantitatively evaluate the meal consumption of the diner, and further evaluates the nutrient intake of the diner through a special algorithm to promote healthy diet;
(2) compared with an intelligent dining mode based on face recognition, the device can not bind and reveal personal information of diners, and information safety is guaranteed;
(3) the device utilizes a high-precision weighing sensor, matches a special weighing and metering algorithm, marks diners by combining an RFID (radio frequency identification) identification technology, and can analyze the actual meal taking weight, the actual meal weight and the actual nutrient intake content of the diners in real time and quantitatively by utilizing a wireless communication means.
The utility model discloses a get meal metering equipment by oneself based on RFID discernment is favorable to realizing quantitative analysis diner volume information of having a meal, solves the extravagant problem of grain that traditional meal, the mode of having a meal exist.
