3.2 WORKING PRINCIPLE

3.2.1 General

This section contains a functional description and detailed theory of operation of the equipment. A system

block diagram of the Controller is shown in Figure 3.2 and 3.3.

Temperature control can carry through the air-circulation system as figure 3.1. After the air outside is purified and is filtrated, it can go into the constant temperature hood from the air-intake of the incubator through the fan driving, and then recycle to the fan by place with a draught. All fresh and recycling air are led through nearby the airflow sensor and heater. The air can pass through the sensor equipped with probe of temperature sensor, which includes themistor of air temperature control and themistor of over-air-temp alarm.

3.2.2 Temperature Control

Temperature is regulated using either incubator Air or Skin temperature as the controlling parameter; the

desired mode is selected by the front panel keys.

In either mode of operation, the heater output is proportional to the amount of heat required to maintain the desired temperature. In air mode，the air temperature can be maintained from 25 to 37ºC (over-ride mode: 37～38℃ ).A sensor located in the Sensor Module and compared with Air Set Temperature setting monitors air temperature. The information from this sensor is supplied to heater control circuitry which regulates the heater output to maintain the Air Temperature setting. In the event that over temperature limit is activated, the heater is shut off. Under this control mode, skin display window will display the temperature on the skin temperature sensor; if the skin temperature sensor isn’t inserted, the skin display window will display “--. -”.

In skin mode，the infant’s temperature can be selected from 34.0 to 37.0ºC (over-ride mode: 37～37.5 ℃ ) .A temperature sensor is attached directly to the infant’s skin; the information from the sensor is supplied to the heater control circuitry, which proportions the heater output to maintain the Skin Set Temperature. In Skin Temperature Mode, the Skin Temperature will be displayed on Skin Temperature Display Window; the Air Temperature Display Window will display the Air Temperature for information only. A second sensor within the air temperature sensor serves as a backup to limit the maximum Incubator temperature. In the event that over temperature limit is activated, the heater is shut off.

3.2.3 Alarms

Alarm is used for monitoring the temperature control system state. The system will check the state by the alarm checkout procedure. When the checked data is abnormal, it will alarm. Table 3.2 listed alarm condition.
