Wireless dish ordering system based on WinCE

Abstract

The invention provides a wireless dish ordering system, comprising an upper computer, a node sending and receiving network and at least one hand-held dish ordering terminal. The upper computer is connected with the node sending and receiving network via a serial port line; the node sending and receiving network is communicated with the hand-held dish ordering terminal wirelessly; the node sendingand receiving network comprises a first microprocessor and a first wireless communication module; the first microprocessor is electrically connected with the first wireless communication module; the hand-held dish ordering terminal comprises an ARM component, a second microprocessor and a second wireless communication module; and the ARM component and the second wireless communication module are both electrically connected with the second microprocessor. The wireless dish ordering system in the invention has strong antijamming capability and can update data in real time.

Description

technical field [0001] The invention relates to a novel wireless ordering system based on WinCE. Background technique [0002] The rapid development of Internet of Things technology is gradually infiltrating people's necessities of life. The promotion of wireless ordering system in the catering industry is a typical application. Through the investigation, it is found that the current wireless ordering systems used in restaurants mainly have the following shortcomings: First, the wireless ordering system under the single-chip microcomputer is low in cost, but the single-chip data storage capacity is small, the processing speed is slow, and it lacks a friendly human-machine interface; Second, the wireless ordering system under infrared or bluetooth has limited ability to pass through obstacles, and the anti-interference ability is poor, so it is not suitable for places with large population flow in restaurants; However, it is easy to be interfered, and the real-time data upd...

Problems solved by technology

Through investigation, it is found that the wireless ordering system currently used in restaurants mainly has the following deficiencies: 1. The wireless ordering system under the single-chip computer is low in cost, but the data storage capacity of the single-chip computer is small, the processing speed is slow, and it lacks a friendly man-machine interface; Second, the wireless ordering system under infrared or Bluetooth has limited ability to pass through obstacles, and has poor anti-interference ability, so it is not suitable for restaurants with a lot of population flow; third, the operation interface of the PDA wireless ordering system is more humanized, with gorgeous colors, However, it is easy to be disturbed, and the real-time data update ability of the menu is not strong; 4, it lacks multi-functional voice broadcast and multi-language support functions, the customer base is limited, and it is prone to repeated points or missing points; 5, the timeliness is not strong , the newly added and sold out dishes are not reflected in the menu in time, and cannot meet the needs of customers in real time
