The invention discloses an air conditioning system control method and device applied to a bus, wherein an air conditioning system comprises infrared temperature measuring equipment which is arranged within each area divided in the bus and used for detecting the temperature of each area. The air conditioning system control method applied to the bus comprises the step of receiving temperature data fed back by the infrared temperature measuring equipment and used for representing the temperature of the area of the infrared temperature measuring equipment; receiving a body parameter, which is fedback by intelligent terminal equipment and used for representing a corresponding user of the intelligent terminal equipment, and a position parameter, which is fed back by the intelligent terminal equipment and used for representing the position of the user; and controlling the output of the air conditioning system according to the temperature data, which is fed back by the infrared temperature measuring equipment, and the body parameter and the position parameter, which are fed back by the intelligent terminal equipment. According to the air conditioning system control method and device applied to the bus, problems that the air conditioning output of the bus in the prior art is controlled by a central control device in a unified manner and cannot be intelligently adjusted according to individual differences of users are solved; the intelligent control of the bus air conditioning system is improved; and furthermore, the user experience is also improved.
