The inner single-chip microcomputer B that is provided with of described water heater links to each other with study button, wireless communication chips IC and control mainboard respectively; Single-chip microcomputer receives the control mainboard that is transmitted to water heater after the efficient communication data of hand-held remote controller or network controller by serial ports, the study button respectively with hand-held remote controller and network controller to sign indicating number; Hand-held remote controller is that timesharing is finished with network controller with communicating by letter of mainboard of water heater control.
The wireless communication module of hand-held remote controller of the present utility model and water heater control mainboard is realized two-way information exchange, and transmission speed is greater than 9.6Kbps, and remote control distance can penetrate a wall at least greater than 30 meters.It is simple and reasonable, cost of manufacture is low, flexible operation, control range are big, makes people's life more convenient.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the Digiplex of present networks water heater comprises the wireless communication module of network controller, hand-held remote controller and water heater control mainboard.Frequency adopts the 433MHz frequency range that need not to apply for, multichannel FSK mode meets the relevant regulations that FCC and ETSI authenticate fully.Its concrete index is: two-way communication, transmission speed are greater than 9.6Kbps, and remote control distance can penetrate a wall at least greater than 30 meters.The wireless communication module of water heater control mainboard is finished the two-way communication with hand-held remote controller and network controller, but is that timesharing is finished with communicating by letter of hand-held remote controller and network controller.
Referring to Fig. 2, hand-held remote controller comprises wireless communication module IC, Chip Microcomputer A, EEPROM, keyboard and LCDs composition.Chip Microcomputer A adopts low-power consumption EM78P468N, and this single-chip microcomputer cost is low, the performance height, and liquid crystal display-driving module that inside is integrated is because the integrated further cost that reduces this remote controller of this module; Wireless communication chips IC model is IA4421, and it is low in energy consumption, and sleep pattern has only the standby current of 0.3uA, is fit to very much battery powered hand-held remote controller; EEPROM adopts the device with IIC interface, mainly is to store the remote controller ID sign indicating number that produces at random, and this ID sign indicating number mainly is the coupling remotely-controlled object.This function has been arranged, damaged or lose when user remote controller, the remote controller that only need buy an identical model again can use sign indicating number again; Button adopts the button of soft-touch type, and is convenient to operation; The LCD figure is clear and intuitive.The Chip Microcomputer A control module receives the input of button, interrelated logic according to input drives the liquid crystal display function corresponding, finish man-machine interaction intuitively, this moment Chip Microcomputer A also according to the input function with set communication protocol, send to the wireless communication module that water heater is controlled mainboard by wireless communication chips, also receive temperature and various running status that the water heater mainboard returns simultaneously.
Referring to Fig. 3, water heater comprises single-chip microcomputer B, study button, wireless communication module IC and control mainboard.Wireless communication module IC adopts IA4421, its technical parameter as mentioned above, its function mainly is and hand-held remote controller and network controller are realized two-way communicating by letter.After single-chip microcomputer receives the efficient communication data of hand-held remote controller or network controller, be transmitted to the control mainboard of water heater, also will finish the conversion of agreement therebetween by serial ports.Study button function mainly be finish with network controller and hand-held remote controller to the sign indicating number matching feature, concrete operation is: when the communication module of hand-held remote controller or network remote controller and water heater control mainboard is not mated sign indicating number, the study of communication module of pressing hand-held remote controller and water heater control mainboard simultaneously is to the sign indicating number button, can finish communication module sign indicating number is mated of hand-held remote controller and water heater control mainboard; The study of communication module of pressing network controller and water heater control mainboard simultaneously is to the sign indicating number button, can finish communication module sign indicating number is mated of network controller and water heater control mainboard.The communication module of above hand-held remote controller or network controller and water heater control mainboard sign indicating number is finished respectively.
Referring to Fig. 4, the hand-held remote controller panel comprises LCD and button, and wherein LCD shows that key element comprises that middle guarantor, instant heating, night letter, intelligence, power, temperature show, virgin lock, and anion, reservation, startup and shutdown figures are formed; Its temperature is shown as 0~99 degree, and temperature and actual temperature are set all show at same position, in the time of the digital flicker of temperature,, when the temperature number does not glimmer the actual temperature of the water heater of monitoring for temperature is set.Power can show high, medium and low third gear.Reservation had maximum 9 different reservations, the water time of reservation water heater altogether in one day.Keyboard adopts the button of soft-touch type, is made up of 9 buttons altogether, be respectively be provided with, determine, virgin lock, Based Intelligent Control, cancellation, negative ions, ON/OFF, ▲ with
