// Update temperature status
void setTemperature(const TTXTemperature_S& temperature) {m_Temperature = temperature;}
// Get temperature status
virtual TTXTemperature_S GetTemperature() {return m_Temperature;}
4. Platform Description
4.1 real-time temperature
-
Open [Operations]> Edit [Vehicle]> [Device Info], select the number of sensors in the sensor parameters, and each vehicle can report up to 4 sensors.
-
Select the sensor type as "Temperature Sensor", and give the sensor a custom display name, and finally click save.
Example: Change the default name 'TEMP_1 'to 'Temperature 1'
-
Turn on real-time monitoring, check "Temperature Sensor" in the Map Pop settings and click Save.
-
Refresh the real-time monitoring interface, and display the temperature value in the vehicle status bubble box.
4.2 temperature report
Temperature Alarm Statistics
Statistics of vehicle Ultra-High Temperature Alarm and Ultra-Low Temperature Alarm, alarm times and alarm duration.
Dynamic Temperature Details
query the detailed temperature data of the vehicle and display it in the form of temperature graph.
Temperature Over Details
query the details of the Ultra-High Temperature Alarm and Ultra-Low Temperature Alarm.
5. Precautions
- If the device transmits the temperature value to the platform according to the relevant extension protocol, but the vehicle status bubble box does not display data, please check whether the temperature sensor is checked in the bubble setting of the map.
