Description of drawings
Accompanying drawing 1 is the structural representation of the utility model Intelligent flat air-conditioner LCD display control program.
Specific embodiment
Below in conjunction with drawings and Examples the utility model 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 the 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.
The control module module comprises: the analog signal importation, by some sensors, detect some pressure signals, temperature signal, frequency signal and flow signal, the 2nd MCU on the control module, by the analog-digital converter of self, detect these to such an extent that analog signal conversion is data signal, carry out again computing, thereby judge the ruuning situation of machine, and the situation of external environment condition, realized the perception of machine; The 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; The switching value stimulus part, this device only has the switch two states, and the 2nd MCU judges by the state that detects it whether some parts move; Switching value output, the 2nd MCU add optocoupler and relay is exported the switching value signal that opens or closes, and comes the startup of the parts that switch need to control and stops; 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 is realized 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.
The man-machine interface part is mainly by using HIM (LCD colour liquid crystal display device) to realize, man-machine interface HIM uses 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, operating only needs simple instruction just can finish; Operation part mainly realizes with film key.Our this cover system is that supporting air-conditioner outdoor unit uses, 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 characteristics such as esthetic requirement design of oneself; Storage area has used SD card memory module, and the SD card is bought convenient, and memory space is large, and data are difficult for losing; The real-time clock part, the time that adds DS1302 chip realization system by battery is not lost entanglement.Communication module, the same serial communication interface and the control module module that carries by transceiver and the MCU of model 75LBC184 with the first control module 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.Contact by a MCU plate between operation part and the man-machine interface part.User or guardian need to select 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 the result is set.
Two parts are to come interaction data by communication cable, and two parts can be separately by dress like this, and control section can be by installing to the industry control scene, and the man-machine interface control section can be by installing to the place of being convenient to personnel operation, and man-machine interface is more friendly simultaneously.
