Abstract

The present invention provides a compressor start-up control method and device. The method includes: within a preset period, judging whether there is a first start-up record in a pre-created database; if there is a first start-up record in the database, obtaining The second startup record with the shortest time interval from the current time point; judging whether there is identification information used to represent the successful startup of the compressor in the second startup record; if there is no identification information in the second startup record, then read the second startup record The first update parameter in the record, so that the compressor starts using the first update parameter; judge whether the first feedback information from the compressor is received within the preset first time range; if received within the first time range If the first feedback information is received, a third startup record is generated and stored according to the first update parameter, the first feedback information and preset parameter conditions. This solution can improve the success rate of starting the compressor.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a compressor starting control method and device. Background technique [0002] During compressor startup, the success rate of compressor startup is related to startup load and startup current. Generally, when the starting load is constant and the starting current is within a certain range, the higher the starting current, the higher the success rate of starting the compressor. [0003] At present, before starting the compressor, wait for a period of time to reduce the starting load to a certain extent, and then use a certain starting current to start, if the starting fails, repeat the above operation. That is, the same starting current is used for multiple starts under a certain starting load, so the success rate of starting the compressor is low. Contents of the invention [0004] The invention provides a compressor startup control method and device, which can improve...
