Data communication processing method and device and electronic expansion valve controller

Abstract

The embodiment of the invention provides a data communication processing method and device and an electronic expansion valve controller. Modification of operational control parameters of an electronic expansion valve under the non-halt state is achieved. The data communication processing device comprises an obtaining module, a first encoding module and a first transmitting module, wherein the obtaining module is used for obtaining the first operational control parameter to be transmitted to the electronic expansion valve controller, the first encoding module is used for encoding the first operational control parameter to obtain first data, and the first transmitting module is used for transmitting the first data to the electronic expansion valve controller through an interface converting unit so that the electronic expansion valve controller can obtain the first operational control parameter and a value of a first identification field after the first data are received and can enable the first operational control parameter to be stored into erasable and programmable storage or a temporary storage unit according to the value of the first identification field. According to the data communication processing method and device and the electronic expansion valve controller, the modification of the operational control parameters of the electronic expansion valve under the non-halt state is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a data communication processing method, device and electronic expansion valve controller. Background technique [0002] The electronic expansion valve is to adjust the liquid supply of the evaporator according to the preset program. Because it belongs to the electronic adjustment mode, it is called an electronic expansion valve. It adapts to the development requirements of refrigeration mechanical and electrical integration, has excellent characteristics that cannot be compared with thermal electronic expansion valves, and provides conditions for intelligent control of refrigeration systems. It is a promising self-control energy-saving component. [0003] As a new type of control element, the electronic expansion valve is an important part of the intelligence of the refrigeration system and a symbol of the electromechanical integration of the refrigeration system. It h...
