Fig. 2 is the embodiment schematic diagram of Radio infrared steering wheel controller of the present invention.
Wherein: 1 button, 2 coders, 3 infrared-emitting diodes, 4 infrared receiving diodes, 5 decoders, 6 on-vehicle host, 7 bearing circle.
Detailed description of the invention
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, a kind of Radio infrared steering wheel controller described in the embodiment of the present invention, comprise coder 2, infrared-emitting diode 3, infrared receiving diode 4 and decoder 5, described coder 2 is connected with the button 1 of bearing circle 7, with thinking that each button provides function coding; Described infrared-emitting diode is connected with described coder, sends for the keyboard-coding provided by described coder; The keyboard-coding that described infrared receiving diode is launched for receiving described infrared-emitting diode; Described decoder is connected with described infrared receiving diode, in order to the described keyboard-coding received is carried out decoding, and this decoding is sent to on-vehicle host 6.
In above-described embodiment, each button of bearing circle is all connected with coder, the function coding that each button is corresponding different respectively, during use, after user carries out button operation to a certain button, after encoder accepts to the operation of this button, the function coding of this operation correspondence is launched by infrared-emitting diode, infrared receiving diode receives infrared-emitting diode and launches the function coding of coming, and be transferred to decoder, function coding is compiled into corresponding function button operation information by decoder, and feed back to on-vehicle host, on-vehicle host carries out corresponding keypress function operation according to this button operation information, thus complete whole key presses and manipulation process.
As a kind of preferred embodiment of the present invention, on the basis of above-described embodiment, described coder and the described decoder of Radio infrared steering wheel controller are all connected to vehicle power.Described vehicle power is 3.3V vehicle power.The number of keys of described bearing circle is decided according to the actual requirements, and can be any number of.Described infrared-emitting diode is arranged on described bearing circle.To reduce the distance between the button on infrared-emitting diode and bearing circle, thus reduce connection distance, and then the complex circuit problem that reduction brings because of connection, user can be repaired or replaced the parts oneself being easier to keep in repair in simple connection line, avoid huge service expenditure that maintenance department brings and time cost etc.
As a kind of preferred embodiment of the present invention, on the basis of above-described embodiment, the described infrared receiving diode of Radio infrared steering wheel controller is arranged on nearly on-vehicle host place.In the scope that Infrared Transmission allows, physical distance between maximum reduction infrared receiving diode and on-vehicle host, reduce the connection distance between on-vehicle host, and then the complex circuit problem that reduction brings because of connection, user can be repaired or replaced the parts oneself being easier to keep in repair in simple connection line, avoid huge service expenditure that maintenance department brings and time cost etc.
In sum, Radio infrared steering wheel controller provided by the present invention, adopts Infrared Transmission to replace traditional Hard link line to connect, make connection line simple, and infrared transmission signal is stablized, and is not easily damaged, also can not because of receiving vibration or disturbing and affect normal use.
As shown in Figure 2, in one embodiment of the invention, total 1-5 five buttons on bearing circle, five buttons are connected with coder U1 respectively, and the key information of generation is sent to coder, and coder is after coding, function coding is sent by the infrared-emitting diode D1 connected thereon, meanwhile, this coder connects the vehicle power of 3.3V, and this is the mechanism that bearing circle is installed; Figure right side is depicted as the mechanism that on-vehicle host is installed, be specially the function coding that infrared receiving diode D2 receives infrared transmission diode D1 transmission, and be transferred to its decoder U2 connected, decoder U2 carries out decoding to this function coding, and result is sent to the microprocessor of on-vehicle host, the microprocessor of on-vehicle host carries out corresponding operation according to the decode results received, and this decoder also connects the vehicle power of 3.3V simultaneously.
