Question

我是C＃的新手。

请您告诉我如何获得显示在以下代码的textBox1上的pressureValue的移动平均值。

wrapper.GetDeviceSensorValue(pressure, ref pressureValue);
wrapper.GetDeviceSensorValue(flow, ref flowValue);

this.textBox1.Text = pressureValue.ToString();
this.textBox2.Text = flowValue.ToString();

Answer 1

下面是我所做的移动平均线。我的压力读数没有任何问题。对于Flow读数，我在高读数方面遇到了问题。例如，我期望的是34L / min，但是我的程序只能读取32至33 L / min。

谢谢。

            // get values to test
            wrapper.GetDeviceSensorValue(pressure, ref this.vitalPressure);
            wrapper.GetDeviceSensorValue(flow, ref this.vitalFlow);
            {
                int i;
                float value1 = 0;
                float value2 = 0;
                int numReadings =3000000;
                float vital1;
                float vital2;

                for (i = 0; i < numReadings; i++)
                {
                    wrapper.GetDeviceSensorValue(pressure, ref this.vitalPressure);
                    value1 = value1 + this.vitalPressure;
                }
               vital1 = value1 / numReadings;
                this.textBox1.Text = vital1.ToString("0.##");
                System.Threading.Thread.Sleep(1);

                for (i = 0; i < numReadings; i++)
                {
                    wrapper.GetDeviceSensorValue(flow, ref this.vitalFlow);
                    value2 = value2 + this.vitalFlow;
                }
               vital2 = value2 / numReadings;
                this.textBox2.Text = vital2.ToString("0.##");
                System.Threading.Thread.Sleep(1);
                }
