The invention discloses a control system for a split air conditioner. The control system for a split air conditioner comprises an AC / DC conversion circuit for converting an AC mains supply into a first DC power supply, a DC / DC conversion circuit used for transforming the voltage of the first DC power supply and converting the first DC power supply into a second DC power supply to drive components and parts in the control system for the split air conditioner to operate, a high-voltage control CPU used for generating driving and adjusting signals according to the control signals of a low-voltage control CPU, a variable-frequency drive circuit used for converting the first DC power supply into AC signals according to the driving and adjusting signals to adjust the operation state of the motor, and a low-voltage control CPU for being connected with a control panel and generating control signals according to operating information on the control panel. Through implementation of the control system disclosed by the invention, when the control panel is operated by people, the risk of electric shock is not liable to generate and remote control of a non-networked air conditioner can be achieved.
Description
technical field [0001] The present invention relates to the control field of air conditioners, and more specifically, relates to a control system of split type air conditioners. Background technique [0002] Air conditioners, also known as air conditioners, can adjust air parameters such as air temperature, humidity and air velocity through their own work to meet the needs of people's lives. Due to their versatility and practicality, air conditioners have become more and more popular. It has increasingly become one of the indispensable electrical appliances in people's life. [0003] In the current air-conditioning control system, its low-voltage control and high-voltage control are often integrated in the same control circuit, and the control circuit is often connected to a control panel. When someone tries to control the air conditioner by operating the control panel, the control circuit is directly connected to the mains ( China is 220V / 50Hz), once the control circuit is...
