One. Open-source project introduction

Intelligent parking lot management / parking fee collection / property management / IoT / self-service payment system, professional IT team, multiple years of research and development in the parking lot field, senior architect deployment architecture. Real online operation of millions of level projects! Large group VIP supplier! Our goal: a parking lot system, manage global parking lots, manage and split accounts without mistakes!

The code is completely open source, there is no authorization problem, completely self-created, there is no back door, and no third-party private jar packages are used, the performance and security are completely self-controlled, do whatever you want, it's that arbitrary, and subsequent updates will continue to update deployment tutorials. The code is professionally standardized, newbies can understand, and high-hands like to use. This system is completely free.

Two. Function overview

①This parking lot system is compatible with the mainstream cameras on the market, and theoretically compatible with all hardware, and can be flexibly extended.

②After the camera recognizes the data, it is automatically uploaded to the cloud and recorded, and the camera's unique ID and hardware serial number are verified to prevent illegal data entry.

③Users can query and pay for parking records on their mobile phones (supporting WeChat, Alipay, bank interface payment, supporting different merchants for each parking lot to collect payments), and after payment, they will automatically lift the gate within the free time.

④Supports querying nearby parking lots on the app (navigation, available parking spaces, parking lot fees, coupons, ratings, and comments), and booking parking spaces.

⑤In the event of a power outage or network failure, staff can use the app to take control of the hardware and manually input parking records.

Three. Technical selection

Development Language

• Cloud System: Java
• Hardware Development: C/C++

Development Framework and Architecture

Front-end:

• 【APP】: Flutter (native hybrid framework, not web encapsulation, native application, one code directly generates native Android and iOS applications), neither losing performance nor reducing development costs.
• 【Mini Program/H5/Public Number】: uni-app (underlying framework Vue), one code directly generates h5 (directly deployed public number), WeChat mini program, can be packaged as a hybrid app, one arrow three birds, economical and practical, and also a mainstream development framework in the market.
• 【Backend Management】: vue-element-admin, a very popular backend management template at home and abroad, we use the TypeScript version.

Server:

• Java Framework: [SpringBoot2] [Dubbo2.7.3]
• Database Interface: [MyBatis]
• Real-time Communication IM: Netty4
• Database: MySQL (Common Business Data and Important Data Storage), MongoDB (Storage of Chat Content), Redis (Cache of High-frequency Non-real-time Data), ElasticSearch (Mass Data Full-text Retrieval and Large-scale Data Log Service)
