Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of Intelligent flat air-conditioner LCD display control program of the present invention.
Specific embodiment
Below in conjunction with drawings and Examples, the inventive method is described in further detail.
The Intelligent flat air-conditioner LCD display control program of lift-launch on novel intelligent off-premises station.High-intelligentization is mainly reflected in control module part, and Intelligent flat air-conditioner LCD display control program has partly carried a plurality of peripheral modules at control module, works in coordination and has realized Based Intelligent Control.
Control module module comprises: analog signal importation, by some sensors, detect some pressure signals, temperature signal, frequency signal and flow signal, the 2nd MCU on control module, by the analog-digital converter of self, these are detected to such an extent that analog signal is converted to data signal, then carry out computing, thus the ruuning situation of judgement machine, and the situation of external environment condition, realized the perception of machine; Analog signal output part, is the chip of the digital to analog converter of TLV5630 by model, and the data signal that the 2nd MCU is handled well is converted to analog signal, and main function is the device of realizing the 2nd MCU output or regulating some analog convertings; Switching value stimulus part, this device only has switch two states, and the 2nd MCU judges by the state that detects it, and whether some parts move; Switching value output, the additional optocoupler of the 2nd MCU and relay are exported the switching value signal opening or closing, and carry out the startup of the parts that switch need to control and stop; The second communication module, serial communication interface and human-computer interaction module that transceiver and the 2nd MCU by model 75LBC184 carries carry out 485 communications, and swap data, realizes the real-time close cooperating of two parts; The second insulating power supply module, isolating switch power, is this system power supply.
Man-machine interaction unit mainly comprises a MCU, man-machine interface part, storage area, real-time clock part, the first communication module and the first insulating power supply module.
Man-machine interface part is mainly by being used HIM (LCD colour liquid crystal display device) to realize, man-machine interface HIM is used the liquid crystal display that carries data storage and character library, control flow just can be controlled by corresponding order with simple serial ports or spi mouth, the memory module of drive IC, control IC and store picture data that liquid crystal display self is integrated, operates and only needs simple instruction just can complete; Operation part mainly realizes with film key.Our this cover system is that supporting air-conditioner outdoor unit is used, and the operating mode of use is outdoor, needs equipment to have certain water proofing property.So we have used thin film switch, because thin film switch has certain water proofing property, profile size, layout and outward appearance can be according to the features such as esthetic requirement design of oneself; Storage area has been used SD card memory module, and SD card is bought convenient, and memory space is large, and data are difficult for losing; Real-time clock part, adds DS1302 chip by battery and realizes the time of system and do not lose, entanglement.Communication module, serial communication interface and control module module that transceiver by model 75LBC184 the same as the first control module and a MCU carry are carried out 485 communications, and swap data is realized the real-time close cooperating of two parts; The first insulating power supply module, isolating switch power, is this system power supply.Between operation part and man-machine interface part, by a MCU plate, contact.User or guardian, select to need the project of setting by operation push-button, and the parameter that needs setting is set.The project of display screen display operation and data, and demonstrate running status, can reflect intuitively result is set.
Two parts are to carry out interaction data by communication cable, and two parts can be separately by dress like this, and control section can be by installing to industry control scene, and man-machine interface control section can be by installing to the place of being convenient to personnel's operation, and man-machine interface is more friendly simultaneously.
The concrete operational process of system is as follows: press starting key, LCD display, demonstrates state and the parameter of all parts.The first communication module, sends to control module by power-on command.Control module, by the second communication module, receives after the instruction of man-machine interface, and machine enters power on mode, by switching value output module controlled circulation pump, brings into operation.By analog output module, start compressor.By analog input module detected pressures signal, when pressure signal reaches setting value, by switching value output module, control blower fan again and move successively (10bar opens one, and 12bar opens two).Human and machine interface unit is understood the real-time running status that demonstrates.
Now completed start, enter into the state of normal operation, control module detects the water temperature of water circulation by analog input unit, the frequency of frequency converter, the pressure of compressor, with the temperature difference of environment temperature, the 2nd MCU carries out PID computing to these data and passes through analog output module again, switching value output module, regulates.
When having there are abnormal conditions, machine enters guard mode.Comprising: high voltage protective; Low-voltage variation; High temperature protection; Hydrojet protection; Differential pressure security; Discharge protection; Oil liquid level protection; Oil temperature protection.And by abnormal situation, show and save.The more convenient maintenance of attendant.
Although the present invention with preferred embodiment openly as above; but embodiment and accompanying drawing are not for limiting the present invention, be anyly familiar with this skill person, without departing from the spirit and scope of the invention; from working as, can make various changes or retouch, but equally within protection scope of the present invention.What therefore protection scope of the present invention should be defined with the application's claim protection domain is as the criterion.
