The invention has simple operation, strong function, and abundant display information and nomination design, to supply convenient temperature feeling to user.
Description
Technical field
The present invention relates to a kind of full automatic vehicle air-conditioner control system.
Background technology
Air conditioning for automobiles can be divided into three phases according to the process of development both at home and abroad: the automotive air-conditioning system of no controller, the automotive air-conditioning system that controller is arranged and full automatic automotive air-conditioning system.The automotive air-conditioning system of no controller has only hot and cold two kinds of selections, can't bring comfortable enjoyment to the occupant; Automatically the automotive air-conditioning system of (being self-control) is with high costs, is used in mostly on the high-grade automobile.Therefore advantages such as and the full automatic vehicle air-conditioner control system had both had the intelligent function of full automatic car air-conditioner control system, and it is low to have use cost again, easy to maintenance have vast market the most, thereby have been subjected to the favor of numerous automobile vendors.
Summary of the invention
The present invention towards medium-to-high grade automobile, provides a cover full automatic vehicle air-conditioner control system for overcoming the deficiencies in the prior art.
The technical solution used in the present invention is: comprise compressor, air blast etc., described compressor, air blast connect the microcontroller of embedded system PsoC (the mixed signal array design of programmable system on chip), adopt CapSense (capacitance touch sensing interface) technology of PSoC, utilize capacitance detecting and tactile keyboard operation control.
The present invention is easy and simple to handle, powerful, have abundant demonstration information and human oriented design, for the occupant provides comfortable temperature sensation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a control flow chart of the present invention;
Fig. 2 is the principle schematic of capacitance touch sensing interface CapSense.
The specific embodiment
As shown in Figure 1, 2, be the mechanical knob formula operation that solves existing air-conditioner control system, dull demonstration, particularly control problems such as function is abundant inadequately, the invention provides a kind of tactile keyboard operation, the air-conditioner control system of abundant control function and display interface.The technical issues that need to address comprise the realization of keyboard, LCD demonstration and control algolithm etc.The PSoC Express of Cypress Semiconductor Co., Ltd is the developing instrument that first item can be developed the microcontroller design, it is developing instrument at PSoC (programmable system on chip) mixed signal array, the present invention adopts this cover advanced person's embedded system PSoC to carry out the design of circuit and algorithm software for this reason, utilizes its strong functions to realize required target.
At first, adopt PSoC advanced person's capacitance touch sensing interface CapSense technology, only with hand refer to touch the interface will form one with being electrically connected of embedded type sensor, these sensors are worked with the PSoC device, convert the position data of pointing to various system control functions and utilize capacitance detecting, realize simple and reliable keyboard operation.Secondly, utilize the powerful internal circuit function of PSoC, construct the less circuit of a cover peripheral components, in convenient design, greatly improved the integration and the robustness of system.The 3rd, adopt the distinctive C Compiler of PSoC, Compiler mainly supports Java to arrive the compiler and the related service of this machine code, realizes the Embedded Application of high-level language, for the program of control algolithm realizes providing a great convenience, help in the future function expansion and upgrading simultaneously.The 4th, adopt the PSoCExpress technology, realize the Synchronization Design of hardware and software; The 5th, adopt the FlashSecurity technology, realize physical protection to embedded system program,
Major function of the present invention and operating procedure are as follows:
(1) refrigerating function
(1) general refrigeration mode
Satisfy following three conditions simultaneously, start general refrigeration mode.
Pressure switch is normal
The environment inside car temperature is greater than 1 ℃ of set temperature value
The air outlet temperature is high-end more than or equal to the return difference temperature
(2) forced refrigeration pattern
Under general refrigeration mode, if design temperature is set under 13 ℃, the temperature setting district shows LO, compressor force start.This moment, blower speed was adjustable, and the wind direction motor position is adjustable, and new wind air door is closed.System pressure should be normal under this pattern, and evaporator defrost is normal.
(2) heat-production functions
(1) general heating mode
When water temperature 〉=55 ℃, fan starting begins to send warm braw to heat, and water temperature reduces gradually; When water temperature≤25 ℃, close blower fan, stop to send warm braw to heat, when blower fan is not worked simultaneously, show current water temperature.
(2) force heating mode
Under general heating mode, temperature is set to HI (＞xx ℃) occurring, enter the pressure heating mode.This moment, hot water valve was opened, and cold and hot air door forwards to and heats side, and the air blast air quantity is adjustable.The wind direction motor position is adjustable, and new wind air door is closed.Not just influenced by water tank temperature.
(3) automatic function
(1) compares according to design temperature and vehicle interior temperature, select refrigeration or heating mode to carry out work automatically.
(2) the air quantity grade superlative degree is 8 grades, and air quantity is that the fiducial value according to vehicle interior temperature value and setting value increases or reduces, and the air quantity size can not increase and reduce key adjusting air quantity by air quantity this moment.
(4) wind direction and air quantity control
(1) do not freeze under the funnel draught state and also do not heat, hot water valve is closed, and air quantity can be regulated, and the wind direction state presents the duty of memory.
(2) mode switching key control air door blower fan is five kinds of states: blow head, blow pin, blow head blows pin, blows pin+wind screen defrosting simultaneously.Constantly press mode switching key, then conversion in order.
Cyclic process: blow head → blow pin → blow head blows pin → blow pin defrosting → blow head
(3) whenever press air intake circulation key once, switch between the two states: advance new wind and interior circulation.
Advancing new wind is that Che Nei and car carry out the air switching outward.
Interior circulated air be in the car between the circulation of air.
(5) defrost function
No matter which kind of duty the wind direction options button is in, only to wind screen defrosting.
Want to close defrost function, the blow head state at first occur by the wind direction switch key.
(6) internal and external temperature handoff functionality
Whenever press the internal and external temperature switch key once, can switch demonstration indoor temperature and outdoor temperature.
(7) compressor delay protection
The time interval that double compressor is opened can not be less than 6s.
(8) memory function
Again start after the power down, the liquid crystal display content displayed is identical with content displayed before the power down, and maintenance duty last time is constant; And can write down various system error messages and other parameters of using to the current time.
