Problems solved by technology
In the related technology, the timing will only start after the communication fails, and it will be judged as abnormal communication after N minutes. During this period, the communication success rate will not be identified, and it is impossible to judge whether there is an interference signal in the communication circuit.
In addition, the air conditioner is easily affected by factors such as power grid quality, installation environment, and field wiring during actual installation, resulting in failure of current loop communication
When the communication is abnormal, the communication fault code will be reported directly, and professionals must come to the door for maintenance, which increases the after-sales pressure of the merchant, and the user experience is not good

The invention discloses an anti-interference control method and device of a current loop communication circuit for an air conditioner, a storage medium, the air conditioner and the communication circuit. The anti-interference control method of the current loop communication circuit for the air conditioner comprises the following steps: 1, after communication is established between an indoor unit and an outdoor unit, the communication frame loss rate between the indoor unit and the outdoor unit is detected; and 2, when it is determined that the communication frame loss rate is larger than a first preset value, communication parameters between the indoor unit and the outdoor unit are adjusted so as to reduce the communication rate between the indoor unit and the outdoor unit. Therefore, theanti-interference control method of the current loop communication current for the air conditioner can automatically process abnormal signals, improve the data transmission reliability of the air conditioner, reduce the probability of air conditioner shutdown caused by communication faults and improve the user experience.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an anti-interference control method for a current loop communication circuit for an air conditioner, a computer-readable storage medium, an anti-interference control device for a current loop communication circuit for an air conditioner, and an anti-interference control device for an air conditioner current loop communication circuit. A current loop communication circuit and an air conditioner. Background technique [0002] During the operation of the air conditioner, data exchange is required between the indoor unit and the outdoor unit. In order to ensure the reliability of data transmission, a strong current loop is usually used for two-way communication. In the related technology, the current loop communication method of the air conditioner is a half-duplex asynchronous serial communication, and the communication steps are that the indoor unit (master) first ...
