method one, see fig. 2 for a description:
step 1-1, an outdoor main fan system reads a target air volume range value sent to an indoor range hood bound with the outdoor main fan system;
step 1-2, adjusting the rotating speed of an indoor motor of the currently running indoor range hood according to a target air volume range value, measuring the actual air volume of the indoor motor, and then sending the actual air volume of the indoor motor, the rotating speed of the indoor motor and floor information to an outdoor main fan system;
step 1-3, selecting an indoor range hood of which the actual air volume is not within the target air volume range value from the currently-operated indoor range hood by the outdoor main fan system;
step 1-4, judging whether the number of the indoor range hoods selected in the step 1-3 is larger than 0, if so, entering the step 1-5, and if not, entering the step 1-8;
step 1-5, acquiring the indoor motor rotating speed of the indoor range hood selected in the step 1-3;
step 1-6, the outdoor main fan system acquires the normal fan rotating speed range of the indoor range hood of the floor corresponding to the indoor range hood of the indoor range hood selected in the step 1-3; corresponding to the normal fan rotating speed range of the floor, the outdoor main fan system can be stored in advance;
step 1-7, judging whether the rotating speed of an indoor motor of the indoor range hood of the corresponding floor is within the normal rotating speed range of a fan of the indoor range hood of the corresponding floor, if so, outputting that the abnormal air outlet of an indoor air outlet branch pipe of the floor needs to be overhauled, and outputting the floor of the indoor range hood; if not, the indoor range hood outputting the floor is wrongly bound with the outdoor main fan system;
step 1-8, sequencing the indoor motor rotating speeds of the indoor range hoods currently running according to the floor from high to bottom or from low to high;
step 1-9, judging whether the rotation speed of the indoor motors after sequencing is abnormal in jumping, namely whether the rotation speed of the indoor motors after sequencing is arranged in a sequence from small to large or from large to small, if so, selecting the floor of the indoor range hood with jumping, and outputting that the indoor range hood on the floor is wrongly bound with the outdoor main fan system; if not, outputting that no binding error phenomenon is found;
in the method, the actual air volume screening of the indoor range hood is performed firstly to check the indoor range hood bound to the outdoor main fan system, for example, the machine information of the A flue 10 building is bound to the outdoor main fan system of the B flue roof, so that when the B flue outdoor main fan system counts the total air volume, the assumed B flue is low in turn-on rate, and the B flue outdoor main fan system gives a 14m air volume3The target air quantity value of/min can reach 14m through corresponding adjustment because the total opening probability of other machines in the B flue is low3About/min, however, the actual physical meaning of the wrongly bound 10 floors is in the flue A, the outlet pressure and the working condition are actually limited by the flue A, and the air volume of the 10 floors can only reach 11m under the condition that the open rate of the flue A is high and the congestion is relatively high3Min or lower, obviously not in the B flue at 14m3And/min is close to the target, and the screening is easy. When the actual air volume is not within the target air volume value, the oil fume absorption electrode in the inner chamber is screened out, further confirmation and judgment can be carried out, if the rotating speed of the indoor motor is not within the normal range, as the gear or current adjustment of the indoor motor in the building 10 reaches the maximum value, but the resistance of the A flue is too large, the resistance cannot reach 14m3The target of/min is that the actual working rotating speed at the moment is high (the highest gear or the maximum current is operated), the range of the actual working rotating speed exceeds the range of the ordinary normal working rotating speed, and the indoor range hood of the floor is most likely to be bound to the outdoor main fan systems at the tops of other flues; if the actual wind volume of the 15-storied building reaches 16m3Min, target of 14m3The min is still large or small, the air outlet pipeline of the indoor range hood is likely to fall off or be damaged at the moment, so that the machine is in a partially or completely non-pipe-carrying state, and the gear or current of the motor of the machine is the minimum allowed normallyThe value and the air volume are still larger, but the rotating speed is still in a normal range, and a prompt is required to synchronously overhaul the branch pipeline.
