1. The background of restaurant delivery
With the severe situation of the national catering industry and the acceleration of transformation and upgrading, the development momentum of the popular catering industry has not fallen but has risen, especially represented by the fast food industry. However, the intensive dining period in the fast food industry is very obvious, especially in restaurants with delivery service in the store. This is often the case: customers order and pay and get the number plate to sit casually. After the dishes are produced, the waiters run around the hall with their plates. To find the location of the customer, due to the long waiting time of the customer, the customer is irritated and dissatisfied, and the waiter is also resentful because of the search. Although the restaurant decoration is high-grade, it has caused the overall image to decline.
Nowadays, many fast food restaurants are divided into double floors or rooms. In this case, the food delivery work becomes more complicated.
2. ZigBee food delivery business flow
1. Work flow chart
Using the ZigBee intelligent networking positioning technology, the system automatically tracks and obtains the customer’s dining location and intelligently displays it on the screen.
2. Process introduction
(1) After the customer arrives at the store, they can find an empty seat randomly. A ZigBee table card will be fixed on each table, and the customer can call the waiter over to order through the table card;
(2) The table card for ordering is bound to the position of the table, and you can always see which table needs service on the computer terminal;
(3) The waiter places the order to the kitchen with the brand number as the order number;
(4) The food passer can find the table number of the brand on the touch screen after seeing the brand number on the dish ticket, and directly send the dishes to the customer’s table and retrieve the table card;
(5) The waiter can identify the table where the customer is at the fastest time, saving time for both parties. If the customer waits for too long, for example, if the first dish is not delivered after 15 minutes, the system will remind the waiter;
(6) When the customer is ready to leave after the meal, they can press the pay button on the table card, and the waiter can come over immediately
Three, ZigBee meal delivery customer experience
1. Quickly and accurately locate customers and increase the speed of serving dishes
Since the location of each customer is uncertain, the waiter needs to find the customer first, and then deliver the meal. This takes an average of 2 minutes. If the restaurant is upstairs and downstairs, it will take more time. According to the peak lunch and dinner period , 50 tables, 100 customers dining calculation, the time for the delivery staff to find customers is 200 minutes.
If the ZigBee food delivery desktop intelligent positioning system is used, the waiter no longer needs to find the customer, and directly delivers the meal to the customer. It takes about 20 seconds, which saves 83% of the time.
2. Improve customer satisfaction
Fast food customers have very high requirements for meal time. Therefore, in addition to the speed and standardization of dishes, it is also very important to improve the speed of delivery. This small detail is often the key to victory, allowing your company to be ahead of its peers. step.
3. Save manpower, material resources and financial resources
Since fast food restaurants have obvious time periods for intensive dining, they are very busy when they are busy and require a lot of manpower. When they are not busy, they are idle and waiters are redundant. Now it is very difficult to recruit workers. Therefore, it is difficult to solve the workload of waiters during peak periods. The essential.
After installing the ZigBee desktop intelligent positioning system, the time for waiters to find customers is reduced, and a restaurant with 50 tables can save at least two people. At the same time, it reduces the labor intensity of waiters looking for customers and makes them enter the work with a happy mood, which indirectly improves work efficiency.
4. Increase the turnover rate of fast food restaurants and increase turnover
The speed of serving meals directly leads to the acceleration of customers’ meals, thereby increasing the turnover rate and increasing turnover.
5. Modern management, increase competitiveness
Modern management methods will enhance the image of fast food restaurants and increase their competitiveness. The chain store headquarters can see the occupancy rate of all branches at any time through the Ethernet.
Fourth, product selection
1. ZigBee positioning menu
Built-in RFID low-frequency module, with the antenna facing upwards. ZigBee wireless transmission module, the appearance needs to be designed and opened. The effect diagram is as follows. The menu is powered by a lithium battery, and one charge can take one month:
2. ZigBee repeater and receiver
Using the master-slave topology, the PC controls the ZigBee master through the serial port to communicate with each ZigBee slave in a polling manner. For the remote slaves, the master-slave communication requires a repeater.
