Automatic engineering vehicle air-conditioning control method

Abstract

The invention discloses an automatic engineering vehicle air-conditioning control method and relates to the technical field of automobile air-conditioning control. The method adopts a controller consisting of a central processing unit, a signal acquiring module, a signal pre-processing circuit module, a driving circuit module, a keying module, a liquid crystal display module and a power module. A system automatically adjusts air amount of an air blower, an alternating current (AC) working state, a blowing mode and an inner / outer air switch working state according to a set temperature value and a temperature signal in a vehicle, and displays the working states through a display screen of the liquid crystal display module. The automatic engineering vehicle air-conditioning control method has the advantages of automatically controlling temperature and air amount, integrating cold ventilation and warm ventilation, being good in interference resistance and superior in water proofing, dust proofing and salt mist proofing, having undervoltage overvoltage protection and input-output short circuit protection, and displaying a current working state and fault code information in real time.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning control, in particular to an automatic engineering vehicle air-conditioning control method, which is suitable for the engineering vehicle air-conditioning system. Background technique [0002] At present, there are various types of air-conditioning controllers for engineering vehicles, and knob-type analog controllers and manual electronic air-conditioning controllers occupy the main market. The knob-type analog controller has no under-voltage and over-voltage protection function, poor anti-interference ability, and no good man-machine display interface. Although the manual electronic air-conditioning controller for construction vehicles has made up for the shortcomings of the knob type and is more intelligent, it cannot realize automatic control and is not humanized enough. The display interface is not good and the waterproof and dustproof performance of the product is not goo...
