edgecomputing-ats（边缘计算 ATS）

ATS (Automatic Ticket System) Analyzer

Analyzes the EdgeComputing ATS project for architecture understanding, device management, and codebase navigation.

ATS Project Overview

ATS is an edge computing gateway for automatic ticket systems, managing multiple hardware devices (IC card readers, QR scanners, LED/LCD displays, card dispensers/collectors, etc.) and communicating with cloud platforms.

Project Location

/home/forlinx/Documents/trae_projects/workspace/EdgeComputing/ats/

Key Documentation

• docs/系统架构文档.md - System architecture (layered architecture, modules, communication)
• docs/项目概述文档.md - Project overview (features, users, components)
• docs/用户操作手册.md - User operation manual
• docs/设计说明书.md - Design specification (interfaces, protocols, algorithms)

Architecture Layers

Layer 1: Application Layer

• robot/ats-robot-server/ - Main service (core business logic)
• robot/ats-robot-lcd-app/ - LCD application (HMI)

Layer 2: Common Libraries

• common/ats_common/ - Serial, network, database utilities
• common/ats_common_device/ - Device abstraction layer (20+ device types)
• common/ats_media/ - Video capture/encoding
• common/ats_protocol_api/ - Uplink protocol (cloud communication)
• common/ats_protocol_robot/ - Downlink protocol (device communication)

Layer 3: Device Drivers

• device/io/ - IO devices (GPIO, relay)
• device/ic/ - IC card readers (multiple vendors: dy, hh, jt, yc, robot)
• device/qr/ - QR/barcode scanners
• device/led/ - LED displays
• device/provide/ - Card dispensers
• device/collect/ - Card collectors
• device/plate/ - License plate recognition
• And more (printer, env, aircond, alarm, etc.)

Core Device Types

Key Classes

CNodeService (Main Service)

class CNodeService : public CService {
    // Device management
    CATSIODevice*        m_pIODevice;
    CATSProvideDevice*   m_pProvideDevice;
    CATSCollectDevice*   m_pCollectDevice;
    CATSQRDevice*        m_pQRDevice1;
    CATSLEDDevice*       m_pATSLEDDevice;

    // Business management
    CCoilManager*        m_pCoilManager;
    CKioskManager*       m_pKioskManager;

    // Communication
    CMQTTServer*         m_pMQTTServer;
    CDYProtocolServer*   m_pDYProtocolServer;
};

Device Base Class

class CATSBaseDevice : public CBaseInterface {
    virtual BOOL Open(...) = 0;
    virtual void Close() = 0;
    void SetStatusHandle(CATSBaseDeviceStatusHandle* pHandle);
};

Communication Architecture

Cloud Communication (Uplink)

• HTTP Server (Port 8080)
• WebSocket (Port 8081)
• MQTT (Port 1883)
• GB28181 (Port 5060)
• RTSP (Port 554)

Device Communication (Downlink)

• Serial (RS232/RS485/UART)
• TCP/UDP Network
• CAN Bus
• GPIO

Message Protocol Examples

Heartbeat (Uplink)

struct ATSCmdHeartonline {
    unsigned int dwDeviceId;
    unsigned char byStatus;
    unsigned char byNetwork;
    unsigned short wDeviceType;
    unsigned int dwOnlineTime;
};

Card Provide Command

struct ATSCmdCardProvide {
    unsigned int dwCardType;
    unsigned int dwCardNum;
    unsigned char byAction;  // 1-issue, 2-recycle
};

Compilation

cd ats/build-aarch64
./build.sh

Usage Guidelines

1. When user asks about ATS architecture, reference the documentation in docs/
2. When analyzing device code, look in device/{type}/ for vendor-specific implementations
3. When analyzing protocol code, look in common/ats_protocol_*/
4. Device abstraction is in common/ats_common_device/

Triggers

• User asks about ATS project structure
• User needs help understanding device protocols
• User wants to add new device support
• User asks about system design or architecture
