Abstract
The invention discloses a variable power controlled truck air condition controller, relating to an electronic truck air condition controller. The controller is provided with an MCU (Micro-programmed Control Unit), and a signal acquisition module, a state display module, a power supply processing module and a load driving module, which are connected with the MCU respectively, wherein the signal acquisition module comprises a key acquisition module, a sensor acquisition module, a pressure acquisition module and a voltage acquisition module; the load driving module comprises a compressor PWM (Pulse-Width Modulation) driver, an evaporation fan PWM driver and a condensation fan PWM driver; the sensor acquisition module comprises an air returning sensor, a defrosting sensor and an outdoor sensor. Under different temperature conditions, a compressor, an evaporation fan and a condensation fan are driven by different powers so that aims of saving energy sources and improving the comfort of a human body are realized.
Description
Technical field
The present invention relates to a kind of electronic type truck air conditioning controller, specifically a kind of truck air conditioning that becomes power control
Controller.
Background technology
On truck, air-conditioning system all is housed at present, can regulates vehicle interior temperature to a comfortable state.Conventional controller mostly is mechanical, hand-driven mode of operation and motorized adjustment mode.When temperature is reduced to the design temperature of temperature controller, compressor will quit work.When temperature is elevated to the design temperature of temperature controller, compressor will be started working.The unlatching of compressor and stop automatically being completed by temperature controller.But the output of the air-conditioner controller of most is all after opening, compressor, evaporation fan, condensation fan full-speed operation, after closing, these loads stop fully.Such working method can make temperature bring larger fluctuation, not only waste energy, and human feeling's comfort level also can reduce.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of truck air conditioning that power is controlled that becomes
Controller, save the energy, improves human comfort.
The present invention realizes with following technical scheme: become the truck air conditioning controller that power is controlled, comprise the MCU microcontroller, the signal acquisition module be connected with MCU respectively, state display module, power supply processing module, load driver module; Described signal acquisition module comprises button acquisition module, sensor acquisition module, pressure acquisition module and voltage acquisition module; Described load driver module comprises that compressor PWM drives, evaporation fan PWM drives and condensation fan PWM drives; Described sensor acquisition module comprises return air sensor, defrosting sensor and outdoor sensor; The MCU microprocessor is by button acquisition module input message, return air sensor partial pressure value, outdoor sensor partial pressure value, defrosting sensor partial pressure value, through the MCU microprocessor, table look-up, the logic judgement and relatively after, the control load driver module is with different capacity work.
The invention has the beneficial effects as follows: under different temperature, with different power powers compressor, evaporation fan, condensation fan, thus maximized satisfied refrigeration requires and energy-conservation requirement, reduces energy consumption, saves the energy, and increase human comfort.
The accompanying drawing explanation
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is schematic block circuit diagram of the present invention.
The specific embodiment
As shown in Figure 1, the truck air conditioning controller of change power control has a MCU microcontroller, the signal acquisition module be connected with MCU respectively, state display module, power supply processing module, load driver module; Described signal acquisition module is in order to the acquisition controller external signal; Described state display module is in order to the display controller running status; Described power supply processing module is in order to power supply; Described load driver module is in order to drive outside actuator.
Wherein, described signal acquisition module comprises button acquisition module, sensor acquisition module, pressure acquisition module and voltage acquisition module; Described load driver module comprises that compressor PWM drives, evaporation fan PWM drives and condensation fan PWM drives; Described sensor acquisition module comprises return air sensor, defrosting sensor and outdoor sensor; Described button acquisition module comprises rise key, down key, on & off switch and sleep button.
The course of work: the MCU microprocessor is by button acquisition module input message, return air sensor partial pressure value, outdoor sensor partial pressure value, defrosting sensor partial pressure value, through the MCU microprocessor, table look-up, then respectively according to the difference of vehicle interior temperature and design temperature, with different PWM drive compression machine controllers, from controlling the rotating speed of compressor, and then control the refrigerating capacity of compressor.Same, according to the difference of vehicle interior temperature and design temperature, drive evaporation fan with different PWM.Can, according to the height of outdoor temperature, determine to drive the height of condensation fan power.Under different temperature, control strategy is separately arranged like this, thereby maximized satisfied refrigeration requires and energy-conservation requirement.
When having a narrow range of temperature, controller drive compression machine, evaporation fan, condensation fan be with smaller Power operation, holding temperature that can be stable.When the temperature difference was large, controller drove the load full-speed operation, and temperature descends rapidly.By contrast, temperature is also just before more stable than not adopting this control mode, thereby the comfort level of human body is improved.
The above is a kind of of the preferred embodiments of the disclosure, within those skilled in the art carries out in the technical solution of the present invention scope common variation and replacement all should be included in protection scope of the present invention.
