Abstract
The utility model discloses an external air conditioner control system based on power line carriers. The external air conditioner control system comprises a PLC intelligent controller connected with an air conditioner real machine. The PLC intelligent controller is in communication with a smart phone or an upper computer through wireless converting equipment. According to the external air conditioner control system based on the power line carriers, an existing air conditioner and power lines are used, a new intelligent air conditioner is of no need, rewiring is of no need, and the problem that the smart home and intelligent appliances are not harmonious in development in the current air conditioner field is solved. According to the external PLC air conditioner controller, an air conditioner information managing function is integrated so that a user can achieve the functions of controlling, information searching, protecting and the like on an air conditioner via the external PLC air conditioner controller only through any network connected into any network operator.
Description
Technical field
The utility model belongs to intelligent electric appliance product technical field, is specifically related to a kind of external air-conditioner control system based on power line carrier.
Background technology
The Smart Home industry of China was risen the latter stage of the nineties in last century, and along with the raising of living standards of the people, the Smart Home industry of China has obtained swifter and more violent development and has day by day been penetrated in the middle of ordinary citizen's life.Current domestic intelligent appliance is not developed widely along with the development of Smart Home, and the slower development of intelligent appliance has directly had influence on the development of Smart Home.The air-conditioning of producing on Vehicles Collected from Market does not have long-distance intelligent control function, cannot integrate with Smart Home direction.Even if the additional controller with Long-distance Control needs to lay separately control circuit, control mode is relatively backward, need to set up control circuit, and hardware cost is higher.So be necessary external power line carrier (PLC) air-conditioner controller of development based on power line carrier, solve the matching problem of Smart Home and intelligent appliance, save special control circuit simultaneously and lay, greatly provide cost savings.In the situation that existing air-conditioning is all superseded, the additional external air-conditioner controller based on power line carrier is a best selection, has realized long-distance intelligent home control, has saved improvement cost, effectively utilizes existing airconditioning condition.
Utility model content
The purpose of this utility model is to provide a kind of external air-conditioner control system based on power line carrier, has solved existing intelligent appliance and can not realize the problem of Long-distance Control.
The technical solution adopted in the utility model is, based on the external air-conditioner control system of power line carrier, comprises the PLC intelligent controller being connected with air-conditioning real machine, and PLC intelligent controller is communicated by letter with smart mobile phone or host computer by wireless conversion equipment.
Feature of the present utility model is also, PLC intelligent controller wherein, comprise control signal change-over circuit, on control signal change-over circuit, be connected with respectively AC-DC multiple power supplies, air-conditioning Ethernet interface and RX bandpass filter, the other end of RX bandpass filter is connected with control signal wave detector, on control signal wave detector, be also connected with electromagnetic interface filter, electromagnetic interface filter is also connected with AC-DC multiple power supplies.
The beneficial effects of the utility model are, utilize existing air-conditioning and power line, do not need production of intelligent air-conditioning and rewiring again, have broken Smart Home and intelligent appliance and have developed inharmonic situation in current field of air conditioning.The external PLC air-conditioner controller that adopts, integrate air-conditioning information management function, make the user only need to be by any network of any Virtual network operator of access, utilize external PLC air-conditioner controller in the utility model just can complete the functions such as control to air-conditioning, information inquiry, protection.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of the external air-conditioner control system of the utility model based on power line carrier, as shown in Figure 1, comprises the PLC intelligent controller being connected with air-conditioning real machine, and PLC intelligent controller is communicated by letter with smart mobile phone or host computer by wireless conversion equipment.
The structure of PLC intelligent controller as shown in Figure 2, comprise control signal change-over circuit 1, on control signal change-over circuit 1, be connected with respectively AC-DC multiple power supplies 2, air-conditioning Ethernet interface 6 and RX bandpass filter 4, the other end of RX bandpass filter 4 is connected with control signal wave detector 5, on control signal wave detector 5, be also connected with electromagnetic interface filter 3, electromagnetic interface filter 3 is connected with AC-DC multiple power supplies 2.
Electromagnetic interface filter 3 wherein, the PLC control signal of filtering 100MHz; AC-DC multiple power supplies 2 is the power supply of PLC air-conditioner controller; Control signal wave detector 5, detects the control signal of being sent by wireless conversion equipment; Control signal change-over circuit 1, converts control instruction to control signal and sends to air-conditioning; Air-conditioning Ethernet interface 6, transmission control instruction is extracted in the control signal being coupled on power line by modulation-demodulation technique, and converts control instruction to and send to air-conditioning equipment by Ethernet interface.
The course of work of the present utility model is, PLC control signal is coupling on power line by special electromagnetic interface filter 3, and filtering PLC control signal, makes PLC control signal all flow to control signal wave detector 5; AC-DC multiple power supplies 2 is the power supply of PLC air-conditioner controller; Control signal wave detector 5 detects the PLC control signal of being sent by wireless conversion equipment by RX bandpass filter 4, transmission set specific frequency signal on power line; By control signal change-over circuit 1, control signal is converted to control instruction and send to air-conditioning.
