Laboratory fruit sample automatic weighing system

Abstract

The invention discloses a laboratory fruit sample automatic weighing system which comprises a computer, a serial port line and a fruit sample weighing device, the computer is connected with the serial port line, the other end of the serial port line is connected with the fruit sample weighing device, the fruit sample weighing device obtains weight data of a fruit sample, the serial port line imports the data into a computer database, the fruit sample weighing device comprises an upper layer and a lower layer, a scale is arranged in the middle of the upper layer, the lower layer is a box body, a high-precision weighing sensor, a circuit, a battery, an HYD4216 buzzer, an A / D conversion module, an amplification filter and a power management module are arranged in the box body, a main control chip ATmeg328 serves as a controller of the circuit, and data are transmitted through a USB-to-RS232 serial port module. An automatic weighing APP is arranged on the computer, the APP is connected with the database, automatic weighing can be achieved, corresponding data can be stored, and meanwhile operation such as data adding, data deleting, data modifying and data checking can be achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit automatic weighing, in particular to a laboratory fruit sample automatic weighing system. Background technique [0002] With the development of science and technology, people are exploring the world faster and faster. The exploration of fruit samples is one of them. At present, there are various laboratory fruit sample weighing equipments on the market. These equipments often only have high precision, but the storage of data is ignored. At present, laboratories generally use computers to record data, and when When the amount of data is huge, querying data is slow, which not only wastes time, but also wastes human energy. Therefore, the reform of laboratory fruit sample weighing equipment has become a trend. Contents of the invention [0003] The technical problem solved by the present invention adopts following technical scheme to realize: [0004] The laboratory fruit sample automatic weighin...
