c# - 如何使用 c# 设置遥测频率以向物联网设备发送消息
问题描述
我有以下代码成功地将数据发送到物联网设备。现在我想设置遥测时间跨度以连续发送数据如何配置任何指导?
private static async void SendDeviceToCloudMessagesAsync(string deviceid , string deviceKey)
{
deviceClient = DeviceClient.Create("hostname", new DeviceAuthenticationWithRegistrySymmetricKey(deviceid, deviceKey), Microsoft.Azure.Devices.Client.TransportType.Mqtt);
double minTemperature = 20;
double minHumidity = 60;
int messageId = 1;
Random rand = new Random();
while (true)
{
double currentTemperature = minTemperature + rand.NextDouble() * 15;
double currentHumidity = minHumidity + rand.NextDouble() * 20;
var telemetryDataPoint = new
{
messageId = messageId++,
deviceId = deviceid,
temperature = currentTemperature,
humidity = currentHumidity
};
var messageString = JsonConvert.SerializeObject(telemetryDataPoint);
var message = new Microsoft.Azure.Devices.Client.Message(Encoding.ASCII.GetBytes(messageString));
message.Properties.Add("temperatureAlert", (currentTemperature > 30) ? "true" : "false");
await deviceClient.SendEventAsync(message);
Console.WriteLine("{0} > Sending message: {1}", DateTime.Now, messageString);
await Task.Delay(1000);
}
}
基本上我在这里使用
while (true)
了我想设置的而不是这个1.从每个设备输入格式发送遥测数据的频率是 HH MM SS
2.多长时间模拟运行 inout 格式是 HH MM SS UI 屏幕
