== 概述 / Overview ==
MDCS 的车队调度被分为两层：'''SimpleCore'''（核心算法库，包含交管、寻路、包络、可达性、DPS 等内核算法）与 '''SimpleComposer'''（基于 SimpleCore 的 UI 壳层，包含 CAD 工具、可视化、插件宿主）。本页面对开发者：你想自己写一个调度应用（或在 SimpleComposer 之外用 SimpleCore 内核）该如何开始。

MDCS fleet management is split into two layers: '''SimpleCore''' (algorithm library — traffic control, pathfinding, envelopes, reachability, DPS) and '''SimpleComposer''' (a UI shell built on SimpleCore — CAD tool, visualisation, plugin host). This page targets developers writing their own scheduling app on top of SimpleCore, or extending SimpleComposer with a custom car / mission type.

== 何时基于 SimpleCore 开发 / When to use SimpleCore directly ==
{| class="wikitable"
! 场景 / Scenario !! 建议 / Recommendation
|-
| 集成进非 SimpleComposer 的现成系统 || 直接用 SimpleCore，把 UI 留给原系统
|-
| 给 SimpleComposer 加车型 / 业务 || 写插件在 SimpleComposer 上挂载，不必自己写调度
|-
| 算法研究（新交管 / 新寻路） || SimpleCore，作为算法宿主
|-
| 单工位单车 || 都不需要，写一个小循环够了
|}

== 核心抽象 / Core abstractions ==
=== Car 体系 / Car hierarchy ===
SimpleCore 把"车"按照 ''是否使用 MDCS 车载系统'' 分为两支：
SimpleCore splits "cars" into two branches by whether they use the MDCS on-vehicle stack:

{| class="wikitable"
! 类 / Class !! 文件 / File !! 用途 / Use
|-
| `AbstractCar` || `D:\src\Simple\SimpleCore\PropType\AbstractCar.cs:346` || 调度可见的车的最小契约 / minimal scheduling contract
|-
| `Car` || `D:\src\Simple\SimpleComposer\RCS\Car.cs:33` || SimpleComposer 中的"车"基类 / Composer-side base
|-
| `ClumsyCar : Car` || `D:\src\Simple\SimpleComposer\RCS\ClumsyCar.cs:34` || 跑 MDCS 车载（Medulla + Clumsy）的车 / runs full MDCS on-vehicle stack
|-
| 自评估 `Car`（自定义子类）/ Self-eval `Car` (custom subclass) || 各 vendor 适配代码 / vendor adapters || PLC / 磁导航 / 二维码类无车载 PC 的车 / cars without on-board MDCS (PLC, magstrip, QR)
|-
| `AGVInterface` || `D:\src\Simple\SimpleCore\BasicProps\AGVInterface.cs` || 任务脚本调用的 API / API surface called by mission scripts
|}

=== AGVInterface 与 Queue 机制 ===
`AGVInterface` 暴露给任务脚本（TopazScript）的核心方法是 `Queue(params Func<Task>[] actions)` —— ''超标量'' 异步流水线：

The core method on `AGVInterface` exposed to mission scripts is `Queue(params Func<Task>[] actions)` — a "super-scalar" async pipeline:

* 每个 Func 是一个 ''行 / row''，按提交顺序进入流水线。
* 同一行内的代码顺序执行。
* 上一行未完成前，下一行不会开始 —— 但下一行可在上一行最后一个 await 后立即 schedule，达成宏观流水。
* `WaitAsync(int pipe)` 让调用方等到指定行完成再继续。

* Each Func is a '''row''' in the pipeline.
* Code within a row runs sequentially.
* The next row only starts after the previous row's last await, but its prelude can overlap, giving macro-level pipelining.
* `WaitAsync(int pipe)` lets the caller wait for a specific row.

=== TryLock / Leave — 交管 / Traffic control ===
`TryLock(int siteID)` / `Leave(int siteID)` 是 SimpleCore 交管在 ''每个 mission 脚本里''的钩子。任务脚本在进入一个交管区前必须 `TryLock`；离开时 `Leave`。SimpleCore 的内核保证：

`TryLock(siteID)` / `Leave(siteID)` are SimpleCore's traffic-control hooks ''per mission script''. Scripts must `TryLock` before entering a controlled segment and `Leave` on exit. SimpleCore's kernel guarantees:

* 无死锁（DPS 算法，见 [[Special:MyLanguage/DPS调度算法详解|DPS调度算法详解]]）<br />Deadlock freedom (via DPS — see the DPS page).
* 公平（按到达顺序授予锁）<br />Fairness — locks granted in arrival order.
* 兼容性（同一锁可被声明 ''可兼容车型'' 一起持有）<br />Compatibility — a lock can be held simultaneously by compatible car types.

== 写一个 ClumsyCar 子类 / Subclassing ClumsyCar ==
ClumsyCar 用于车上跑完整 MDCS（Clumsy 自动驾驶 + Medulla 硬件抽象）的情况。最小子类骨架：

ClumsyCar is the right base when the vehicle runs the full MDCS stack on-board. Minimal subclass:

<syntaxhighlight lang="csharp">
using SimpleComposer.RCS;

namespace Vendor.Carts
{
[CarType(Name = "MyCart", Title = "我的车型 / MyCart")]
public class MyCart : ClumsyCar
{
public MyCart() : base()
{
conf = "configs/MyCart.config";
api_retries = 3;
}

public override async Task actualSendScript(string script)
{
// 把 TopazScript 通过 HTTP 发到车载 Clumsy 适配器 / POST to on-board Clumsy adapter
var url = $"http://{address}:30080/run";
var resp = await HttpClient.PostAsync(url, new StringContent(script));
resp.EnsureSuccessStatusCode();
}

public override async Task keepAlive()
{
// 心跳 + 状态轮询 / heartbeat + status poll
var status = await HttpClient.GetStringAsync($"http://{address}:30080/status");
UpdateStatusFromJson(status);
}
}
}
</syntaxhighlight>

参考样例（80 行可读完）：`D:\src\cookbook\adaption-reference\法睿兰达\CartAdapters\FY2208008\Scenes\AMRScene\ProjNameCar.cs`。
Reference (80 lines, easy to read end-to-end): `D:\src\cookbook\adaption-reference\法睿兰达\CartAdapters\FY2208008\Scenes\AMRScene\ProjNameCar.cs`.

== 写一个自评估 Car 子类 / Subclassing Car for self-eval vehicles ==
自评估车（磁导航 / 色带 / PLC 控制 / 二维码等）的车载没有 MDCS，调度只能发"高层意图"，由 ''SimpleCore 侧'' 的 AGV 接口翻译成厂商命令，再通过 RFID / Modbus / HTTP 下发。

Self-evaluating vehicles (magnetic-strip, tape, PLC-controlled, QR-only) don't run MDCS on-board. The scheduler dispatches "high-level intents", and a ''fleet-side'' `AGV : AGVInterface` translates them into vendor commands (RFID frames, Modbus, HTTP) and reads back `(x, y, th, siteID)` via `keepAlive()`.

经典样例：`D:\src\cookbook\adaption-reference\苏州凌鸟\Scenes\AMRScene1\Cars\MNavCar.cs`（293 行，含双向导航 + RFID 命令队列 + 启发式约束容器 `MNavCarHeuristics`）。

Canonical example: `D:\src\cookbook\adaption-reference\苏州凌鸟\Scenes\AMRScene1\Cars\MNavCar.cs` (293 lines — two-way navigation, RFID command queue, `MNavCarHeuristics` for no-go turns / forced reversals).

骨架 / Skeleton:

<syntaxhighlight lang="csharp">
[CarType(Name = "MyMagCart", Title = "磁导航车 / Magnetic-strip cart")]
public class MyMagCart : Car
{
public string address;
public int rfidPort = 502;

public class AGV : AGVInterface
{
private readonly MyMagCart car;
public AGV(MyMagCart c) { car = c; }

public override bool TryLock(int siteID, int route_id) { /* SimpleCore 内置 / inherit */ return base.TryLock(siteID, route_id); }
public override bool Leave(int siteID) { return base.Leave(siteID); }

public void Go(double sx, double sy, int sid, double dx, double dy, int did, int routeId)
{
Queue(
async () =>
{
// 在锁拿到后才发指令 / send intent only after lock granted
if (!TryLock(did, routeId)) return;
car.SendRFIDGoCommand(did);
},
async () =>
{
// 等到车真的到了 / wait until reported arrival
while (car.lastReportedSiteId != did) await Task.Delay(100);
Leave(sid);
});
}
}

public override async Task actualSendScript(string script) { /* 自评估车通常不发 TopazScript */ }
public override async Task keepAlive()
{
// Modbus / TCP 读位置并写入 (x, y, th, siteId) / poll position
var (x, y, th, siteId) = await PollPLCAsync(address);
UpdatePose(x, y, th); lastReportedSiteId = siteId;
}
}
</syntaxhighlight>

== 任务下发 / Mission dispatch flow ==

调度内核 → SegmentPlan.Compile() → TopazScript（一段脚本）
↓
CarProgram.script (放入 Car.status.programs.forecasted)
↓
Car.actualSendScript(script)
↓ (ClumsyCar) ↓ (self-eval)
HTTP POST 到车载直接在调度侧本地跑 SelfEvaluating(agv, script)
↓ ↓
车载 SelfEvaluating(agv, script) AGV.Go / AGV.Queue 等映射到 RFID/Modbus 命令
↓
Clumsy Movement 执行 → 物理运动

== Reachability 与包络 / Reachability & envelope ==
SimpleCore 提供 ''可达性状态机''（见 [[Special:MyLanguage/可达性状态编程|可达性状态编程]]）与 ''包络声明''（见 [[Special:MyLanguage/使用手册 - Simple:包络如何定义|包络如何定义]]）。你的 Car 子类一般只需要：

* 声明默认包络（无载货状态的车体包络）。
* 在带载 / 升叉 / 顶升等状态时声明 ''备用包络''，由 `HaveExtraEnvelope` 状态触发。
* 在不可达的路径段上声明 ''可达性规则''（例如：单向通道、最低剩余电量、强制掉头）。

A Car subclass typically: (1) declares the empty envelope, (2) declares alternate envelopes triggered by carry / fork-up / jack-up states, (3) declares reachability rules on path segments (one-way, min battery, mandatory reverse-out).

== 用作算法宿主：在 SimpleComposer 之外用 SimpleCore ==
SimpleCore 是普通 .NET 库（`D:\src\Simple\SimpleCore\`），可以独立引用。最小集成：

<syntaxhighlight lang="csharp">
using SimpleCore;

var world = new World(); // 加载站点 + 路径图 / load sites + path graph
world.LoadFromJson(File.ReadAllText("map.json"));

var car1 = new MyAbstractCarImpl(); // 实现 AbstractCar 接口
var car2 = new MyAbstractCarImpl();
world.AddCar(car1); world.AddCar(car2);

var planner = new DPSPlanner(world);
var mission = planner.Plan(
from: world.GetSite("A"),
to: world.GetSite("Z"));

foreach (var step in mission.Steps)
{
Console.WriteLine($"car={step.Car} site={step.Site} action={step.Action}");
}
</syntaxhighlight>

= 算法 / Algorithms =
SimpleCore 内置：
SimpleCore ships with:

* DPS 调度（动态规划交管）—— `[[Special:MyLanguage/DPS调度算法详解|DPS调度算法详解]]`
* 寻路启发器 —— `[[Special:MyLanguage/使用手册 - 寻路启发器功能|寻路启发器功能]]`
* 流场规划 —— `[[Special:MyLanguage/流场规划|流场规划]]`
* 网络流业务规划 —— `[[Special:MyLanguage/基于网络流的业务规划器|基于网络流的业务规划器]]`

== 调试 / Debugging ==
* 用 [[Special:MyLanguage/CycleGUI|CycleGUI]] 把交管锁、车辆状态、路径片段实时画出来。
* SimpleComposer 的 ''Trace 面板'' 显示每条任务的 Queue 行执行轨迹。
* 死锁怀疑时打开 ''DPS 决策可视化''（DPS 算法会输出每次决策的剪枝树）。

* Use [[Special:MyLanguage/CycleGUI|CycleGUI]] to render locks, car state, path segments live.
* SimpleComposer's ''Trace panel'' shows the Queue-row execution timeline per mission.
* When deadlock is suspected, enable ''DPS decision visualisation''.
