Train network control method for air-conditioning compressor

Abstract

The invention relates to a train network control method of air condition compressors. The method comprises the following steps that: step one: a train network system judges whether the air condition compressors are about to run, operation ends if so, and step two is carried out otherwise; step two: the train network system sends a starting command to an air conditioning control disc corresponding to a certain air condition compressor; step three: the train network system judges the communication state between the train network system and the air conditioning control disc according to the formula (1), if Y=0, step four is carried out, and operation ends if Y=1; step four: the air conditioning control disc sends a command of starting the corresponding air condition compressor to the corresponding air condition compressor and controls the corresponding air condition compressor to start; step five: the step one is carried out after certain seconds and all the steps are carried out repeatedly on another air condition compressor of a train. According to the train network control method of the air condition compressors, starting time is shortened and control procedures are simplified.

Description

technical field [0001] The invention relates to a method for controlling the startup of an air conditioner compressor through a train network system, in particular to a train network control method for the air conditioner compressor. Background technique [0002] As far as the applicant knows, the existing subway train auxiliary power supply system provides DC110V power supply (low voltage power supply) and AC400V power supply (medium voltage power supply) for on-board equipment. Among them, the air compressors and air-conditioning unit compressors in the medium-voltage power supply load compartment have the characteristics of large power, large number, high start-stop frequency, large start-up current, and easy impact on the auxiliary power supply system. In order to avoid failure of the auxiliary power supply system, in addition to improving the system's tolerance to inrush current, effective measures must be taken to prevent the above-mentioned load devices from starting ...

Problems solved by technology

In the subway train system, when the air conditioner compressor needs to be started, the air conditioner control panel (SACVP) sends a start request to the TCMS, and the TCMS signals whether there is an air compressor (referred to as the air compressor, which is the train braking system) is about to start Determine whether the request time of the air conditioner compressor unit is in its exclusive section, and then TCMS gives the command whether to allow the air conditioner compressor to start. When the command is TRUE, the air conditioner can start the compressor. This control mode The air conditioner and TCMS need to exchange information with each other, and TCMS needs to judge whether the request time is within its time range, resulting in a relatively long startup process and complicated control procedures
