Problems solved by technology

[0003] 1. The main controller controls the slave machines to switch on and off at the same time, so that some unused slave machines must also be turned on at the same time, resulting in energy waste and no energy saving;
[0004] 2. According to the running time of each compressor, some units with short running time are turned on or some units with long running time are turned off, but relying on manual control is very unintelligent and prone to errors or misoperations

Embodiment Construction

[0039] refer to figure 1 , the present invention a kind of automatic circulation switching machine control method, comprises the following steps:

[0040] According to the preset target temperature and temperature difference value, the maximum target temperature and the minimum target temperature are obtained;

[0041] Collect the running time of each unit in real time;

[0042] According to the running time of each unit, each unit is controlled to achieve the corresponding target temperature.

[0043] Further as a preferred implementation, the said control of each unit to implement the corresponding target temperature according to the running time of each unit includes:

[0044] Control the execution of multiple units with the shortest running time to achieve the maximum target temperature;

[0045] Control the execution of multiple units with the longest running time to achieve the minimum target temperature;

[0046] Control the remaining multiple units to execute to ac...

Abstract

The invention relates to an automatic cycle startup and shutdown control method and device. The method comprises the steps: a maximum target temperature and a minimum target temperature are obtained according to a preset target temperature and a temperature difference value; run-time of each set is acquired in real time; and each set is controlled to execute and realize the corresponding target temperature according to the run-time of each set. The system comprises: a temperature difference calculation module, a time acquisition module and a task allocation module. According to the invention, the preset target temperature and the temperature difference value are set according to the users, the operation of sets is allocated according to the length of run-time of each set, so that the run-time of each set is balanced, the operation life of the sets are maintained, the energy waste caused by that some sets which is not necessary to run must be started and run at the same time is avoided. The method and device can be widely applied in a field of set control.

Description

technical field [0001] The invention relates to the technical field of unit control, in particular to an automatic cycle switch machine control method and system. Background technique [0002] In the past, there are usually the following two methods for centralized control of switching on and off: [0003] 1. The main controller controls the slave machines to switch on and off at the same time, so that some unused slave machines must also be turned on at the same time, resulting in energy waste and no energy saving; [0004] 2. According to the running time of each compressor, some units with short running time are turned on or some units with long running time are turned off, but it is very unintelligent to rely on manual control, and errors or misoperations are prone to occur. Contents of the invention [0005] In order to solve the above technical problems, the object of the present invention is to provide an automatic cycle switch machine control method and system tha...
