Abstract

A PLC control system for an aircraft ground air-conditioning device, the system hardware mainly includes 1 SIMATIC226CPU programmable controller, 1 SIMATICEM223I / O module, 2 SIMATICEM231RTDA / D modules, 2 SIMATICEM231A / D modules, and a total of 22 terminal relays, 4 One platinum resistor, six pressure transmitters, one embedded computer, one wireless bridge, and one GPRS module. The system adopts PLC control to control the temperature of the air-conditioning device on the ground of the aircraft, so that the temperature and humidity in the aircraft can be controlled more accurately.

Description

Technical field [0001] The invention relates to a PLC control system for an aircraft ground air-conditioning device, which is suitable for the mechanical field. Background technique [0002] With the continuous development of the economy, the number of aircraft is also increasing. When the aircraft stays on the ground at the airport, it usually uses its own auxiliary power unit to provide power and air conditioning for ground support. However, its use will produce greater operational noise pollution and emissions to the atmosphere. It also increased the operating costs of airlines. Contents of the invention [0003] The invention proposes a PLC control system for an aircraft ground air-conditioning device, which adopts PLC control to implement temperature control on the aircraft ground air-conditioning device, so that the temperature and humidity in the aircraft can be controlled more accurately. [0004] The technical scheme adopted in the present invention is. [000...
