Data communication method, air conditioner, air conditioning system and storage medium

Abstract

The invention provides a data communication method, an air conditioner, an air conditioning system and a storage medium. The data communication method comprises the following steps: acquiring a data reading request; reading register data of the first group of registers, and determining register addresses of the second group of registers according to the register data of the first group of registers; and reading the register data of the second group of registers corresponding to the register addresses of the second group of registers, and sending the register data of the second group of registers. On one hand, an external device can smoothly obtain data only by sending a data reading request, the whole reading process is carried out in a local device, and the external device is not perceived; and on the other hand, as long as the register addresses of the second group of registers needing to be read are set in the first group of registers in advance, the first group of registers can beutilized to read the register data of the second group of registers with the least communication times, the response time of data acquisition is shortened, and the communication efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a data communication method, an air conditioner, an air conditioner system and a computer-readable storage medium. Background technique [0002] Most of the communication between different devices in the field of central air conditioning is based on the Modbus communication protocol. The Modbus communication protocol is a serial communication protocol. To use the Modbus communication protocol, a register table needs to be customized. In the related art, the definition of a register at a certain address is fixed and directly accessed. For example, register [0x00] is used for switching on and off, and register [0x01] is used for setting temperature, then when accessing register [0x00], it is always equivalent to directly accessing the switching register. [0003] But as the register table continues to iterate, this table will become more and more bloated. For exam...

AI Technical Summary

Problems solved by technology

When the table is bloated, because the registers that need to be accessed are often separated by more than 125 addresses, this leads to the need to communicate many times to complete the access to two or three registers, and the communication efficiency is very low.
