Notifying system for calling sequencing numbers

Abstract

The invention discloses a notifying system for calling sequencing numbers, comprising an input module, a first control module, at least one LED (light emitting diode) lighting device and a receiving device, wherein the input module is used for receiving the sequence numbers inputted by a servant and transmitting the sequencing numbers to the first control module; the first control module is used for generating a code signal according to the sequence numbers, and transmitting the code signal to the LED lighting device so as to enable the LED lighting device to flicker with high light and low light; and the receiving device comprises a light receiving model, a second control module and a prompting module, wherein the light receiving module can generate continuously changed response voltage according to the high-low light flicker frequency of the LED lighting device, the second control module is used for decoding the response voltage so as to obtain the sequence numbers and to cause the prompting module to send out a prompting signal. The notifying system for calling the sequencing numbers can achieve the purpose of notifying customers without being restricted by area coverage, and can reduce the cost needed for system construction.

Description

technical field [0001] The invention relates to a notification system for calling sequence numbers, which mainly transmits a coded signal to at least one LED lighting device to cause the LED lighting device to generate corresponding bright and dark flashes, and then uses a receiving device to receive the bright and dark flashes to identify The coded signal notifies the customer (or patient, etc.) to receive the meal (or medicine, etc.) through a prompt module. Background technique [0002] Nowadays, due to busy work and other reasons, the chances of modern people to cook and eat at home are greatly reduced. Relatively, the chances of eating in restaurants are much higher than in the past. At present, many restaurants (such as: restaurants in department stores), in order to reduce the number of restaurant service personnel and save personnel costs, have adopted a meal notification system to notify customers through the notification system when the meal is completed. of custo...

Problems solved by technology

[0005] Just, if the customer stays away from the restaurant (i.e. away from the operating device 10) after ordering food and receiving the receiving device 11, and goes to other areas for consumption or engages in other activities, the receiving device 11 cannot receive the information received by the wireless transmitter 103 smoothly. In this way, even if the service personnel key in the meal number through the input unit 101, the display unit 113 of the receiving device 11 will not have any response. In other words, the customer cannot pass through the receiving device 11 to learn that the meal is complete

In addition, if the restaurant installs multiple sets of wireless transmitters 103 outside the area of ​​the restaurant in order to solve the above problems, the construction cost of the above-mentioned meal pick-up notification system will be too high, and it cannot be popularized in the market, which is not ideal.
