Pipeline Equipment Monitoring

• Monitoring Indicators

  • Equipment Operating Status

    • Standby 1
    • Running 2
    • Stopped 3
    • Maintenance 4
    • Abnormal Shutdown 5

  • Statistical Scheme

    • Equipment working conditions in terms of time

  • Application Scenarios

    • Monitor the status of pipeline equipment, detect equipment failures in time, and ensure the normal operation of the pipeline

  • Wildcard Subscription Mode

    • To avoid losing operating status information due to sensor failures, install multiple sensors and use wildcards to listen
    • Configure listening methods as needed
      • Most resource-intensive, one client listens to all, other topics configure one client per topic
      • Least resource-intensive, only one client listens to all
      • Other configurations, wildcard + specific individual listening methods, can facilitate troubleshooting of sensor failures

  • Signal Content Design

    • Since the status values are relatively simple, only 1-5, there is no need for base conversion for now. The message content is a four-digit fixed device ID + device status

      Example: 00012, the first four digits represent device number 0001, and 2 indicates that the current device is running

  • Configuration Example (only one wildcard is shown here)

    • First, add a client

      The parsing script is as follows

      function main(nc) {
          const deviceStatus = nc.substring(4,5)
          var dataRows = [
              { "Name": "deviceStatus", "Value": deviceStatus }
          ];
          var result = {
              "Time":  Math.floor(Date.now() / 1000),
              "DataRows": dataRows,
              "IdentificationCode": parseInt(nc.substring(0,4)),
              "DeviceUid": "5",
              "Nc": nc
          };
          return [result];
      }
      

      

    • Add signal configuration

      

    • Send simulated data and view the chart

      • The topic for sending simulated data is tp/random

      • IdentificationCode: 5 data situation is as follows

        

      • IdentificationCode: 1 data situation is as follows

        

    • Configure a script alarm

      • Suppose we need to configure an alarm for the status of the machine with identification code 5 on the pipeline, the script we write is as follows

        The script specifies the first item of data named device_bj in the parameter information

        function main(map){
        return  map.device_bj && parseInt(map.device_bj[0].Value) === 5
        }
        

      • Configure the alarm signal

        

      • Send simulated data and check the alarm situation
