Order Meals Online On Chainway Handheld Computers

Background
The end user is a large-scale refinery with scores of employees and a huge area occupied. It takes time for workers to walk from the workplace to the canteen. That’s why some of them prefer to dine out rather than eat at the canteen. The number of diners fluctuate greatly, so sometimes food is insufficient while sometimes surplus. During the given meal time, security guards are hired to maintain order due to high flow of diners. High administrative expense and unreasonable utilization of resources urge the refinery to make a difference.
 
Challenges

• The canteen is far away from workshops. Workers spend too much time on the way.

• It is hard to estimate how many people dine in the canteen and what dishes they prefer, let alone that these figures change every day.

• Extra cost is incurred when security guards are hired during peak dining hours.

 
Solutions
Chainway turns up at the right time to help overcome a series of problems faced by the refinery. A core part of the smart solution is self-developed C4050-Q4 handheld computers with HF RFID reading and writing function. Workers place order on mobile phones in advance, and then all order details are sent to the backend server. This provides real-time basis for the refinery canteen to decide how many dished to be prepared and what they are. Now food delivery service is offered to attract more diners. When the delivery man arrives at each workshop, he uses Chainway C4050-Q4 to read workers’ employee HF cards to know what dishes they have ordered. Accurate delivery is realized from one workshop to another.
 
Effects

• Workers don’t need to spend much time walking to the canteen or lining up in the long queue. Spared time can be saved for afternoon nap.

• Using Chainway handheld computers to read employee cards ensures they receive the exact dishes they order.

• The canteen can prepare food based on the actual demand, effectively eliminating food waste.

• There is no need to hire security guards anymore, helping save cost.

• Food delivery service brings convenience to workers. It also brings more clients to the canteen as a matter of course.
