Temperature control method and device for central air conditioner

Abstract

The invention discloses a temperature control method and device for a central air conditioner. The method comprises the following steps that a short message is received through a GSM module; whether amobile phone number of a mobile phone sending the short message belongs to a user bound with the central air conditioner or not is judged; if the mobile phone number of the mobile phone sending the short message belongs to the user bound with the central air conditioner, content of the short message is identified; if the mobile phone number of the mobile phone sending the short message does not belong to the user bound with the central air conditioner, the short message is deleted or ignored; whether the short message content contains instruction information in a preset format or not is judged; if the short message content contains instruction information in the preset format, the instruction information is converted to obtain a target temperature value which the user desires to set, andthe temperature of the central air conditioner is adjusted to the target temperature value based on a temperature control module; and if the short message content does not contain instruction information in the preset format, whether the short message content is in a query state or not is judged, if the short message content is in the query state, a current temperature value and an indoor state ofthe central air conditioner are sent to the mobile phone of the mobile phone number in the short message form, and if the short message content is not in the query state, the short message is deletedor ignored. According to the method and the device, the set indoor temperature desired by the user is determined in the form of the short message through a GSM network, and a tail end controller of the central air conditioner is controlled based on the set indoor temperature, so that the temperature of the central air conditioner is remotely controlled more accurately.

Description

technical field [0001] The invention relates to the technical field of smart energy, in particular to a temperature control method and device for a central air conditioner. Background technique [0002] The central air-conditioning terminal controller is one of the most important devices in the central air-conditioning system, which is of great significance to the energy saving of the central air-conditioning. There are two types of start / stop control of the air valve at the end of the central air conditioner: manual opening and closing control and fixed-time scheduling air volume control. The control strategy after starting often adopts PID or fuzzy control method to control the indoor temperature. This kind of fixed scheduling algorithm centralized by the central air lift control system, although the control system is easy to implement, it is only suitable for users with fixed load and work and rest time. How to adjust the scheduling time of the terminal air supply device...
