EdgeComputing ATS Analyzer

Analyzes EdgeComputing ATS (Automatic Ticket System) codebase architecture, device protocols, and business logic. Invoke when user asks about ATS project structure, device management, or needs code analysis.

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.

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

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.)

};

Device Base Class

cpp

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

Message Protocol Examples

Heartbeat (Uplink)

cpp

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

Card Provide Command

cpp

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

Compilation

bash

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
