Control method suitable for rotation of parallel equipment

Abstract

The invention discloses a control method suitable for rotation of parallel equipment and relates to the technical field of air conditioning equipment. The control method comprises the steps of 1) determining enabling states of the equipment; 2) when a valve is in states of fault, in-situ, remote manual operation and opening action overtime and the valve is in a state of being opened in position, marking the valve as being preferably used; 3) when a water pump body is in the states, marking the water pump as being prohibited to use; 4) when a cooling machine body is in the states, marking a cooling machine as being prohibited to use; 5) when a cooling tower body is in the states, marking a cooling tower as being prohibited to use; 6) when the equipment is used normally, recording the sequencing time as an accumulated operation time; 7) when it is needed to sequence an equipment group again, carrying out sequencing according to the sequencing time; 8) determining a relationship as follows: preferably used number is smaller than or equal to the lower limit of the number, the lower limit of the number is smaller than or equal to the set operating number, the set operating number is smaller than or equal to the upper limit of the number, and the upper limit of the number is smaller than or equal to the available number; and 9) when the actual operating number is equal to the set operating number, maintaining unchanged control. When the equipment is in abnormal states, various abnormal states are handled comprehensively and timely, so that a self-control system can be operated continuously and efficiently.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a control method suitable for parallel equipment rotation. Background technique [0002] In actual engineering, in order to avoid failure of one device due to long-term continuous operation, multiple similar devices are required to be used in rotation. [0003] In the prior art, similar devices are sorted according to the cumulative running time, and when the devices need to be used, whether the devices are available or not is judged sequentially according to this order. [0004] Example: [0005] There are three water pumps in the system, which need to be used in rotation. The cumulative running time of water pump A is 5 hours, the cumulative running time of water pump B is 2 hours, and the cumulative running time of water pump C is 8 hours. [0006] Sorted according to the cumulative running time, the start and stop sequence of the three water pumps is B, ...

AI Technical Summary

Problems solved by technology

[0010] In the application, because the equipment cannot be used due to some abnormal states, it also needs to be used preferentially due to some abnormal states, and the occurrence of these abnormal states is uncertain

Therefore, in the prior art, either the abnormal state is not considered, or the problem is not fully considered, or the timing is not considered properly. When the abnormal state occurs, the automatic control system will have the problem of improper control.
