水质检测 delphi代码

以下是一个简单的 Delphi 水质检测代码示例，使用了 TChart 组件来绘制水质量的曲线图：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ComCtrls, ExtCtrls, TeeProcs, TeEngine, Chart;

type
  TForm1 = class(TForm)
    btnStart: TButton;
    tmrTest: TTimer;
    chartWaterQuality: TChart;
    Series1: TLineSeries;
    lblResult: TLabel;
    procedure btnStartClick(Sender: TObject);
    procedure tmrTestTimer(Sender: TObject);
  private
    { Private declarations }
    FTestCount: Integer;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

// 模拟水质检测结果
function TestWaterQuality: Double;
begin
  Result := Random(100);
end;

procedure TForm1.btnStartClick(Sender: TObject);
begin
  FTestCount := 0;
  tmrTest.Enabled := True;
end;

procedure TForm1.tmrTestTimer(Sender: TObject);
var
  WaterQuality: Double;
begin
  WaterQuality := TestWaterQuality;
  Series1.AddXY(FTestCount, WaterQuality);
  Inc(FTestCount);
  lblResult.Caption := Format('当前水质检测结果为：%.2f', [WaterQuality]);
  if FTestCount >= 100 then
    tmrTest.Enabled := False;
end;

end.

这个代码示例使用了一个计时器来模拟水质检测的过程，每次检测后会将检测结果绘制到 TChart 组件中。你可以根据需要修改代码来适应你的具体场景。
