Environment Monitoring Principles
About This Chapter
The environment monitoring parameters are reported to the control system through the
monitoring serial port.
In general, environment monitoring involves monitoring of the environment parameters and the
power supply.
l
Environment parameters monitoring means monitoring of the environment parameters, the
abnormality of which may cause failure or damage to the device. The monitoring
parameters include temperature, humidity, water, smoke, MDF, and door status sensor.
l Power monitoring means monitoring of the power supply system, including the mains input,
DC PDU, rectifier unit, and battery.
1.1 Basic Concept
This topic describes the environment monitoring related to the subnode, analog parameter and
digital parameter concepts.
1.2 Environment Monitoring Principle (ESC)
The ESC processes the environment information from relevant sensors to monitor the
environment parameters including indoor temperature and humidity, door status, water, and
smoke. The ESC communicates with the control board through the serial port, and reports the
data to the control board.
1.3 Environment Monitoring Principle (Power Sensor Transfer Box)
The sensor transfer box collects the environment information from relevant sensors and forwards
the information to the monitoring module of the power system. The monitoring module of the
power system then processes the environment information and reports the information to the
control system. With the sensor transfer box, the monitoring function is extended.
