Abstract

The invention provides a control system for data conversion between an air conditioner and an Ethernet, which comprises a power supply circuit, a singlechip control circuit, an Ethernet circuit, a selector circuit and an RS-485 communication circuit; at first, data received from the Ethernet are input into an Ethernet chip receiving buffer zone in the Ethernet circuit; a circuit in the singlechipcontrol circuit is used for reading the data; the singlechip control circuit checks a serial port number in the data and the selector circuit is used for selecting a corresponding RS-485 port according to the port number; the data in a data packet are sent to the corresponding port in the RS-485 communication circuit, and therefore, one Ethernet port is provided with 8 RS-485 ports and an RS-485 chip in the RS-485 communication circuit finishes electric conversion and sends the data to the air conditioner; and on the basis of the original air conditioner, the scheme of the invention adds the data conversion control system between a computer and the air conditioner, thus realizing the control and monitoring of the air conditioner by the Ethernet through the computer or a line controller andcausing the air conditioner to be more humanized and users to have more choices when using the air conditioner.

Description

A kind of data transaction control system that is used between air-conditioning and the Ethernet

Technical field:

The present invention relates to air-conditioning technical field, refer in particular to a kind of data transaction control system that is used between air-conditioning and the Ethernet.

Background technology:

Air-conditioning generally adopts IR remote controller to control at present, by this control mode domestic air conditioning is almost satisfied, but it is not all right to some user prerequisite front opening air-conditioning of wanting to go home, and need very not enough for the control of company and this type of hotel, require energy-conservation such as company, but some employee opens air-conditioner temperature very lowly, is very difficult central controlled with present IR remote controller.

Summary of the invention:

The objective of the invention is to overcome the deficiencies in the prior art.Provide a kind of more humane and be convenient to manage concentratedly be used for data transaction control system between air-conditioning and the Ethernet.

For achieving the above object, technical scheme provided by the present invention is: a kind of data transaction control system that is used between air-conditioning and the Ethernet, and it includes power circuit, single chip machine controlling circuit, ethernet circuit, selector circuit, RS-485 telecommunication circuit; Wherein, ethernet circuit, single chip machine controlling circuit, selector circuit, RS-485 telecommunication circuit are connected successively, and are connected with power circuit respectively; Wherein, the data transaction control system respectively with computer with after air-conditioning is connected, the data transaction control system is at first dynamically obtained IP or is networked by static IP is set, and obtaining behind the effective I P it just can become a terminal on the network, can realize the transmitting-receiving of data on network; The receiving data stream journey: at first the Ethernet chip that the data that receive from Ethernet are installed in the ethernet circuit receives buffering area, read data by the circuit in the single chip machine controlling circuit again, single chip machine controlling circuit is by checking the serial ports port numbers of data the inside, select corresponding RS-485 port according to port numbers by selector circuit, again the data in the packet are dealt into corresponding ports in the RS-485 telecommunication circuit, realized 8 RS-485 ports of an Ethernet interface band, the RS-485 chip in the RS-485 telecommunication circuit is finished electric conversion and is sent to air-conditioning; Send data flow: air-conditioning information is sent in the serial ports of single chip machine controlling circuit from the RS-485 chip in the RS-485 telecommunication circuit, it is good data encapsulation that single chip machine controlling circuit receives the back, the too web-roll core sheet of writing in the ethernet circuit sends buffering area, by Ethernet chip it is sent to computer or line control machine again.

The present invention is after having adopted such scheme, be on the basis of former air-conditioning, between computer and air-conditioning, added the data transaction control system, realized realizing Ethernet control air-conditioning and monitoring air-conditioning, made the user when using air-conditioning, have more selection, hommization more by computer or line control machine; Network air-conditioner can be monitored the temperature of air-conditioning in real time, and can minimum temperature be set by network air-conditioner, can reach air-conditioning centralized management and energy-conservation like this, but also has plenty of remote status inquiry and fault feedback, the main just maintenance of air-conditioning.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Reference numeral: 1-power circuit, 2-single chip machine controlling circuit, 3-ethernet circuit, 4-selector circuit, 5-RS-485 telecommunication circuit.

The specific embodiment:

The invention will be further described below in conjunction with accompanying drawing 1, preferred embodiment of the present invention is: a kind of data transaction control system that is used between air-conditioning and the Ethernet, and it includes power circuit 1, single chip machine controlling circuit 2, ethernet circuit 3, selector circuit 4, RS-485 telecommunication circuit 5; Wherein, ethernet circuit 3, single chip machine controlling circuit 2, selector circuit 4, RS-485 telecommunication circuit 5 are connected successively, and are connected with power circuit 1 respectively; Wherein, the data transaction control system respectively with computer with after air-conditioning is connected, the data transaction control system is at first dynamically obtained IP or is networked by static IP is set, and obtaining behind the effective I P it just can become a terminal on the network, can realize the transmitting-receiving of data on network; The receiving data stream journey: the signal that sends from computer or line control machine is received by ethernet circuit 3, ethernet circuit 3 receives buffering area with the Ethernet chip that the data that receive install in the ethernet circuit 3 then, read data by the circuit in the single chip machine controlling circuit 2 again, single chip machine controlling circuit 2 is by checking the serial ports port numbers of data the inside, select corresponding RS-485 port according to port numbers by selector circuit 4, again the data in the packet are dealt into corresponding ports in the RS-485 telecommunication circuit 5, realized 8 RS-485 ports of an Ethernet interface band, the RS-485 chip in the RS-485 telecommunication circuit 5 is finished electric conversion and is sent to air-conditioning; Send data flow: air-conditioning information is sent in the serial ports of single chip machine controlling circuit 2 from the RS-485 chip in the RS-485 telecommunication circuit 5, it is good data encapsulation that single chip machine controlling circuit 2 receives the back, the too web-roll core sheet of writing in the ethernet circuit 3 sends buffering area, by Ethernet chip data are sent to computer or line control machine again, air-conditioning are managed concentratedly by computer or line control machine.

The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
