The old programmer received a mask project of 30 thousand yuan, and the development cycle was 10 day, which was really fragrant.

The video version is here. I'm the king of the show.

Another case of the mask project, which is directly connected to the hardware through Bluetooth, is to connect the hardware through MQTT.

Program King 80,000 took over the mask project with a development cycle of 1 month.

Project composition

Installation command

Because of the epidemic, the demand for masks has been very strong. Party A's father plans to develop a mask vending machine (similar to a self-service vending machine). This kind of project is actually not new. The program king has also received this kind of mask project before. Don't ask me the meaning of this project. We only do the software part of the mask project, and the hardware and APP parts are developed by another team. This is a partially outsourced project.

Program King 80,000 took over the mask project with a development cycle of 1 month.

APP scans the QR code of vending machine-> Open the H5 collection page-> If there is no collection record, select the type of goods to be collected (masks)-> Receiving and collecting requests in the background->; Send MQTT request to the server->; The MQTT server distributes the request to the vending machine terminal->; The corresponding vending machine receives the request execution instruction (shipment).

Party A provided the application program. We just need to embed it into the H5 page of application development. The function of the first issue is very simple. We can get a mask for free.

This project is actually based on the secondary development of e-commerce projects, and masks are also a commodity. I won't talk nonsense about the function of CRUD when placing an order to buy a typical shopping process. The idea is to connect with hardware interface, and the scheme we adopt is to use Apache Apollo as the message relay station of MQTT.
