Example two
Fig. 2 is a schematic diagram of a regional control network according to an embodiment of the present invention, as shown in fig. 2, which illustrates four rooms as an example, and uses a set of high static pressure ducted air conditioners, including an indoor unit and an outdoor unit; the zone controller is used as a control terminal and can independently control each air valve; an air pipe pipeline for supplying air is connected with an internal machine to each room, each room is provided with an alternating current air valve for controlling the air supply and air outlet conditions, and each air valve can be divided into a low gear, a middle gear and a high gear with controllable opening; meanwhile, a temperature controller is installed in each room and used for detecting the temperature condition in the room in real time and carrying out information interaction with the internal machine in a wireless communication mode. Table 1 shows the judgment control method.
TABLE 1
After the air conditioning unit is powered on, if the air conditioner is always in a shutdown/standby state, detecting and recording the ambient temperature of each room as a standby temperature To;
when the whole machine of the unit is started to operate, the ambient temperature condition of each room is detected at regular time, and the detection is divided into the following two conditions:
1. if the air valve control signal of the room is off, if the ambient temperature Tt and the standby temperature To of the room are detected To meet the temperature condition: if Tt-To | > 2, it means that the air valve cannot be normally closed, and the air valve is abnormally closed under the condition that cold/hot air is mistakenly sent To the room;
2. if the air valve control signal of the room is on, after the room runs for a period of time, judging whether the air valve has an abnormal opening fault according to the opening degree of the air valve and the corresponding running time:
if the opening control signal of the air valve is in a low gear, detecting the ambient temperature Tx of a room after the unit continuously operates for x minutes, if the temperature condition satisfies that | Tx-To | < threshold 1, indicating that the air volume cannot be normally conveyed To the room, the temperature change of the room is not large, and the opening of the air valve is abnormal;
if the opening control signal of the air valve is a middle gear, detecting the ambient temperature Ty of the room after the unit continuously operates for y minutes, if the temperature condition satisfies that Ty-To I is less than a threshold value 2, indicating that the air volume cannot be normally conveyed To the room, the temperature change of the room is not large, and the air valve is opened abnormally;
if the opening control signal of the air valve is high-grade, detecting the ambient temperature Tz of the room after the unit continuously operates for z minutes, and if the temperature condition satisfies that the absolute value Tz-To is less than a threshold value 3, indicating that the air volume cannot be normally conveyed To the room, the temperature change of the room is not large, and the opening of the air valve is abnormal.
It should be noted that different air valve opening degrees affect the speed of the temperature change of the room space, so the relationship of the three minutes of x, y and z should theoretically be x > y > z; however, considering that the space sizes of different rooms are not consistent, the judgment values of three minutes need to be adaptively changed:
for example, the factory default threshold 1 is 2 ═ threshold 3 ═ threshold 2 ═ threshold, x ═ 13, y ═ 11, and z ═ 10. When the unit normally operates, recording the operating time when the temperature change of the room meets a preset value (for example, 2 ℃) after each startup, taking the average value of the latest preset times (three times) of recording time as the fault judgment time of the corresponding gear, and memorizing and storing all the fault judgment time.
For example, if there are five wind gears of the indoor unit and three opening gears of the air valve, 15 fault determination times are involved in the following table.
