Cold Chain Tracking allows the user to:
- Track the real-time temperature
- Receive an alert if the temperature drops below or rises above the enabled Temperature Low and/or High Thresholds, respectively.
There are two types of Cold Chain Tracking mentioned below, namely, static and mobile.
1. Static Cold Chain Tracking:
Static cold chain tracking refers to Temperature tracking only. In this case, we are tracking temperatures between 2 and 6 degrees, which are set as our Low and High Thresholds, respectively. We want to take a temperature sample every 10 minutes and upload every 4 hours. This System Parameters template can be found on OEM, called 'DM Demo - Cold Chain Tracking (Static)'.
The following parameters were set:
- On OEM, select the device and go to Parameters -> Edit System Parameters
- Add the Advanced Tracking parameter tab and set the 'Tracking Mode' to 'Periodic Tracking Only'
- Setting the 'Location Fix on Heartbeat' to 'Yes', allows the device to get a location fix once a day. This 'Heartbeat Upload Period' is set under the 'Basic Tracking' parameters tab
Note: The other settings are GPS related and therefore will not affect the parameter setup when configuring your device for Static Tracking.
- Under the Basic Tracking parameter tab, the 'Heartbeat Upload Period' is set to 720 minutes (12 hours). This allows for a GPS fix once a day.
- The 'In Trip Upload Period' and 'In Trip Logging Period' are also GPS tracking related
- The DM Temp Sensor 1 parameter tab sets the 'Log Analogue Num' to the input number to which you have connected the temperature probe.
- The Analogue Threshold 1 parameter tab allows you to set the Low and High Temperature Thresholds
- 'Analog Input' refers to the above 'Log Analogue Num' you selected in the previous parameter setting, i.e. Input 8
- Enable the Low and High Thresholds, respectively, by setting them to 'Yes'
- The temperature is set by multiplying the degree by 100, i.e. 6 degrees = 6 x 100 = 600
- Enabling Upload/Log on Event determines when the device will log/upload the measured temperatures
- The Hysteresis value allows for leniency of slowly changing inputs, i.e. changing temperatures of less than 0.5 degrees Celsius
- In the Task 1 parameter tab, because we have set the device to 'Periodic Tracking Only', the Out Of Trip Period/Upload Multiplier is set and the In Trip Period/Upload Multiplier is irrelevant
- The 'Out of Trip Period' is set to 10 minutes. This sets the device to log a temperature sample every 10 minutes
- The 'Out of Trip Multiplier' is set to 24. The sets the device to upload every 4 hours
- 'Item 1 type' is set to 'DM Temperature Sensor' - we are measuring temperature readings
2. Mobile Cold Chain Tracking:
Mobile Cold Chain Tracking refers to Temperature and Movement tracking. In this case, we want the device to upload every 30 minutes while in a trip and log a GPS fix every 2 minutes. We also require the device to upload at the start and end of every trip. A System Parameters template can be found on OEM, called 'DM Demo - Cold Chain Tracking (Mobile)'.
- For Mobile Cold Chain Tracking, most Parameter settings remain the same, however GPS tracking is now used to track the device’s movement.
- Under the Basic Tracking parameter tab, the In Trip Upload/Logging Period is now important; this will set the device’s upload/log period when the device is moving.
- The 'In trip Upload Period' is set to 1800 seconds (30 minutes)
- The 'In Trip Logging Period' is set to 120 seconds (2 minutes)
- Under the Advanced Tracking tab, 'Tracking Mode' is set to' Standard GPS Tracking'
- 'Upload on Trip Start' and 'Upload on Trip End' are enabled by setting them to 'Yes'
- Under the Task 1 parameter tab, the 'In Trip Period' is set to log a temperature reading every 10 minutes when moving
- The 'Out of Trip Period' is set to log a temperature reading every 30 minutes when not moving
- The In and Out of trip 'Multiplier' is set to upload every 4 hours
