Remote-control ordering car

Abstract

The invention discloses a remote-control ordering car. A remote controller is used as a standby input device and can be connected to a host through a remote controller cable so that the problems that batteries of the remote controllers are not easy to replace, the standby input devices have poor using experience, the firmware is difficult to update and the like in the prior art are solved.

Description

technical field [0001] The invention belongs to information technology products used in restaurants, in particular to a remote control ordering car. Background technique [0002] With the advent of the digital age, various digital information technology products for restaurants have emerged, such as wireless orderers, touch screen orderers, electronic recipes, service pagers, private room VOD (video on demand) systems, etc. . [0003] After adopting the wireless ordering system, the waiters or customers of the restaurant can order food on various order devices, and then send the order information directly to the kitchen through the wireless network and print it out to the chef, thereby improving the operating efficiency of the restaurant. [0004] The earliest product to appear was a miniature hand-held ordering device (often called "ordering treasure") used by waiters. Due to the need for customers to order dishes while waiters are on duty, the restaurant is often busy du...

AI Technical Summary

Problems solved by technology

In addition, if the input device is changed suddenly, customers will feel very uncomfortable

Again, the backup input device obviously adds to the cost and bulk of Invention A

[0009] The second problem is that the frequency of use of the remote control of Invention A is relatively high

Since Invention A is used in public places, the battery of the remote control cannot be removed casually, otherwise it will be damaged by some customers

If the battery cannot be disassembled casually, it will increase the trouble of replacing the battery in the restaurant

[0010] The third problem is that the remote control of Invention A generally uses a relatively complicated wireless communication protocol, so it is inevitable to upgrade the firmware in the single-chip microcomputer of Invention A from time to time

Due to the poor reliability of wireless communication, there will be more potential problems. Once some problems occur in wireless communication during the upgrade process, which leads to firmware upgrade failure, it can only be recovered by repairing

[0011] The fourth problem is that, under normal circumstances, Invention A generally uses a wireless technology based on frequency hopping similar to Bluetooth to realize wireless remote control

Invention A is generally used at the same time in the restaurant, so if the pairing problem is not solved properly, it is very easy to cause trouble
