Embedded vegetable trading operation terminal on basis of IOT (Internet of Things) technology

Abstract

The invention provides a design of an embedded vegetable trading operation terminal on the basis of an IOT (Internet of Things) technology. A trading operation terminal product technology in a conventional IOT technology is used for reference, the application characteristics of a vegetable trading retroactive terminal are combined, and the embedded vegetable trading operation terminal is suitable to use in the trading environment of a wholesale market with poor environment, large temperature difference and high humidity variation. The embedded vegetable trading operation terminal comprises an industrial grade high-end embedded processor, a card-query storage circuit, an analog quantity and digital quantity acquisition circuit, a driving circuit, a bus circuit, a man-machine interaction circuit, an IOT RFID (Radio Frequency Identification Devices) reading circuit and the like. By external setting or program setting, a vegetable trading operation program and a vegetable trading operation algorithm of the IOT technology are called. The embedded vegetable trading operation terminal can also be used for carrying out corresponding man-machine interaction interface display and data communication of a back stage. The problems that the phenomena of dead halt and instability are generated due to the adoption of common computer external equipment and a special industrial personal computer for the industry is difficult to meet the requirements on the cost and the installation volume are effectively solved. The working efficiency and the quality of the vegetable trading operation working of the IOT technology are improved.
