3. 正则表达式

// Parsers/PlossParser.cs
private static readonly Regex PlossPattern = new(
    @"^FOD->\s+(\d+)\s+\d+\s+\d+\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(-?\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)$",
    RegexOptions.Compiled
);

捕获组映射：

捕获组	字段	类型转换
Group 1	RxType	byte.Parse()
Group 2	RxPower	short.Parse()
Group 3	TxPower	short.Parse()
Group 4	Vcoil	short.Parse()
Group 5	Vin	short.Parse()
Group 6	Isns	short.Parse()
Group 7	Ploss	int.Parse()
Group 8	Threshold	int.Parse()
Group 9	TriggerCount	short.Parse()
Group 10	FodResult	short.Parse()
Group 11	ProtocolType	byte.Parse()
Group 12	PwmDuty	short.Parse()
Group 13	CoilIndex	byte.Parse()

4. 解析器实现

// Parsers/PlossParser.cs
using System.Text.RegularExpressions;
using WCTDataMiner.Models;

namespace WCTDataMiner.Parsers;

public class PlossParser : IParser<PlossRecord>
{
    private static readonly Regex PlossPattern = new(
        @"^FOD->\s+(\d+)\s+\d+\s+\d+\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(-?\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)$",
        RegexOptions.Compiled
    );

    public bool CanParse(string line) => PlossPattern.IsMatch(line);

    public ParseResult<PlossRecord> Parse(string line, int lineNumber, Guid logFileId)
    {
        var match = PlossPattern.Match(line);
        if (!match.Success)
        {
            return ParseResult<PlossRecord>.Failure(
                "FORMAT_MISMATCH",
                "Line does not match Ploss pattern"
            );
        }

        try
        {
            var record = new PlossRecord
            {
                LogFileId = logFileId,
                LineNumber = lineNumber,
                RxType = byte.Parse(match.Groups[1].Value),
                RxPower = short.Parse(match.Groups[2].Value),
                TxPower = short.Parse(match.Groups[3].Value),
                Vcoil = short.Parse(match.Groups[4].Value),
                Vin = short.Parse(match.Groups[5].Value),
                Isns = short.Parse(match.Groups[6].Value),
                Ploss = int.Parse(match.Groups[7].Value),
                Threshold = int.Parse(match.Groups[8].Value),
                TriggerCount = short.Parse(match.Groups[9].Value),
                FodResult = short.Parse(match.Groups[10].Value),
                ProtocolType = byte.Parse(match.Groups[11].Value),
                PwmDuty = short.Parse(match.Groups[12].Value),
                CoilIndex = byte.Parse(match.Groups[13].Value)
            };

            return ParseResult<PlossRecord>.Success(record);
        }
        catch (Exception ex)
        {
            return ParseResult<PlossRecord>.Failure(
                "TYPE_CONVERSION",
                $"Failed to convert field: {ex.Message}"
            );
        }
    }
}

5. 核心判定逻辑

5.1 FOD 触发条件

if (Ploss > Threshold) → 计数器累积
if (Count > Limit) → 触发 FOD 报警，停止充电

5.2 安全余量计算

// 派生属性（不落库）
Margin = Threshold - Ploss

Margin 状态	含义
Margin > 0	安全，损耗低于阈值
Margin < 0	危险，损耗超过阈值，可能触发 FOD

---

6. 动态阈值表

阈值根据接收功率动态查表：

接收功率区间 (Rx Power)	阈值 (Threshold)	备注
0 ~ 5W (0-5000 mW)	350 mW	低功率最敏感
5 ~ 10W (5000-10000 mW)	500 mW
10 ~ 15W (10000-15000 mW)	750 mW
15 ~ 30W (15000-30000 mW)	1000 mW	示例 Log 处于此区间
30 ~ 50W (30000-50000 mW)	1250 mW	高功率允许更多损耗
