Problems solved by technology

[0002] At present, the thermostat commonly used in the air conditioner of engineering vehicles and mechanical vehicles is only for simple temperature control. The heating system can only directly send warm air, but cannot perform temperature control. The direction of air supply can only be adjusted by manually adjusting the louvers of the air outlet. Direction, the position of the air supply cannot be adjusted
The current air conditioner for construction machinery vehicles is only used as a component with a single function of cooling and heating, without considering the driver's comfort and operability

Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] Such as figure 1 As shown, an engineering vehicle air conditioner intelligent temperature controller includes a temperature sensor, an integrated operational amplifier, a CPU, a drive circuit, an executive motor, a speed control module, a display screen, a relay, a fan and a compressor.

[0010] The temperature detection circuit is composed of a temperature sensor 1 and an integrated operational amplifier 2. When the temperature rises, the resistance value of the temperature sensor 1 decreases, and when the temperature decreases, the resistance value of the temperature sensor increases. When the temperature changes, the temperature sensor changes, and the voltage generated on the temperature control sensor also changes accordingly. The integrated operational amplifier 2 amplifies the signal, and then sends it to the input terminal of the single-chip CPU3. Since the s...

Abstract

The invention relates to an intelligent air conditioning temperature controller for an engineering vehicle and belongs to the technical field of electronics. The controller comprises a temperature sensor, an integrated operational amplifier, a central processing unit (CPU), a drive circuit, an execution motor, a speed regulating module, a display screen, a relay, a fan and a compressor. The controller has the advantages of: regulating air supply positions according to the requirements of a cab, ensuring that a singlechip is not influenced by external factors in a multi-level filtering mode, directly displaying control functions on buttons in a graphic mode, and displaying the current state on a liquid crystal display. The displaying is more intuitive, the operation is more convenient and rapid, and a driver can achieve all the needed functions by operating the buttons without getting down the cab.

Description

technical field [0001] The invention relates to a temperature controller, in particular to an intelligent temperature controller for an engineering vehicle air conditioner, which belongs to the field of electronic technology. Background technique [0002] At present, the thermostat commonly used in the air conditioner of engineering vehicles and mechanical vehicles is only for simple temperature control. The heating system can only directly send warm air, but cannot perform temperature control. The direction of air supply can only be adjusted by manually adjusting the louvers of the air outlet. Direction, the position of the air supply cannot be adjusted. The current air conditioners for construction machinery vehicles are only used as a component with a single function of cooling and heating, without considering the driver's comfort and operability. Contents of the invention [0003] In view of the above-mentioned existing problems, the present invention provides an inte...
