Embodiment Construction
[0025] The present invention will be described in further detail below through specific implementation methods in conjunction with the accompanying drawings.
[0026] See figure 1 , shown in the figure is a method for displaying visual evaluation targets of human eyes. Development of an LED signage screen for displaying human visual evaluation targets. The system has no technical requirements for the external bus interface. It is tentatively determined that the RS422 bus interface is connected with the host computer. Its main components are display module, display control module, and power supply module. , the system obtains external power. The system communicates with the outside through the RS422 bus, and receives the display control command sent by the mission system. After receiving the display control module, the display control module analyzes and calls the image data stored in the system in advance according to the command, encodes the image data, and outputs it to the...

The invention discloses a method for displaying a visual evaluation sighting mark of a human eye, which is used for weighing and valuating a weighing object and comprises a weighing unit used for acquiring weight data of the weighing object; a voice recognition module which is used for obtaining voice data provided by the outside and related to the names or codes of the weighing objects, and converts the voice data into coding data corresponding to the voice data according to a voice coding database arranged in the voice recognition module; And a main control CPU which is used for receiving the weight data from the weighing unit and the coded data from the voice recognition module, and obtains the pricing data of the weighing object according to the weight data and the coded data. The invention also discloses a use method of the electronic scale system. The method has the advantages that coded data are input through a speech recognition method, the workload of operators is greatly reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a system and method for displaying visual evaluation targets of human eyes. Background technique [0002] Electronic scale systems used in places such as supermarkets and hypermarkets are essential for bulk weighing of goods. The current electronic scale system often adopts the method of manually inputting the cargo code (in the form of 4-5 digits) and printing the label of the weighing object with its own printer. The disadvantage is that the requirements for weighing personnel are relatively high. Firstly, it is necessary to train the memory of the weighing object code before taking up the job. Secondly, it is necessary to frequently input various codes, which is a great test for people's physical strength and memory. In order to reduce frequent manual input, some operators have compiled shortcut keys for the electronic scale system, and this method can only be used in occasions where there are few types of weighing objects....
