Along with expanding economy, various home appliance is constantly moved in the family life of people.Along with the raising of people's living standard, the requirement of the aspects such as people are easy to use to household electrical appliances, intelligentized control method is also more and more higher.Existing household electrical appliances mostly carry out controlled in wireless by Infrared remote controller, and each home appliance is a corresponding Infrared remote controller respectively.Along with different types of household electrical appliances are constantly moved in family, in family, there is multiple Infrared remote controller.If desired control multiple home appliance respectively, user needs to operate multiple Infrared remote controller respectively, inconvenient operation.
OTG is the abbreviation of On-The-Go, is the technology that developed recently gets up, and Dec 18 calendar year 2001 is announced by USB Implementers Forum, is mainly used in the connection between various different equipment or mobile device, carries out exchanges data.Particularly PDA, mobile phone, consumer devices.Change as multiple different systems connectors of equipment room such as digital camera, video camera, printers, the inconvenience of exchanges data between the storage card reaching 7 kinds of standards.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of infrared transmitter based on OTG interface, to be connected to carry out controlled in wireless to infrared receiving set by OTG interface with mobile terminal.
The purpose of this utility model is achieved through the following technical solutions: a kind of infrared transmitter based on OTG interface, comprise the OTG interface, microprocessor and the infrared transmitting circuit that connect successively, described OTG interface is that mini B socket is for being connected with the mini A socket of mobile terminal, the steering order of mobile terminal receive, and transfer to microprocessor, received steering order is forwarded to infrared transmitting circuit by described microprocessor, and described infrared transmitting circuit launches infrared signal for controlling infrared remote control equipment.
Particularly, described infrared transmitting circuit comprises the first resistance R1, the second resistance R2, infrarede emitting diode D1 and the first triode Q1, first resistance R1 one end is as the input termination microprocessor of infrared transmitting circuit, the base stage Q1 of another termination first triode, the grounded emitter of the first triode Q1, collector is connected and is connect the negative pole of infrarede emitting diode D1 after the second resistance R2, and the positive pole of infrarede emitting diode D1 connects DC power supply.
As preferably, described mobile terminal is smart mobile phone, notebook computer or PAD.
The utility model has following advantage relative to prior art:
The utility model is by arranging OTG interface at infrared transmitter, infrared transmitter is connected with smart mobile phone, notebook computer or PAD by OTG interface as external equipment, realizes smart mobile phone, notebook computer or the PAD infrared remote control to infrared remote control equipment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram based on the infrared transmitter of OTG interface in embodiment;
Fig. 2 is the schematic diagram of infrared transmitting circuit in embodiment;
Fig. 3 is the application principle figure based on the infrared transmitter of OTG interface in embodiment.
Embodiment
Face in conjunction with the embodiments and accompanying drawing the utility model is described in further detail, but the utility model create embodiment be not limited thereto.
Embodiment
As shown in Figure 1, a kind of infrared transmitter based on OTG interface, comprise the OTG interface, microprocessor and the infrared transmitting circuit that connect successively, described OTG interface is that mini B socket is for being connected with the miniA socket of mobile terminal, the steering order of mobile terminal receive, and transferring to microprocessor, received steering order is forwarded to infrared transmitting circuit by described microprocessor, and described infrared transmitting circuit launches infrared signal for controlling infrared remote control equipment.Described mobile terminal is smart mobile phone, notebook computer or PAD.
As shown in Figure 2, described infrared transmitting circuit comprises the first resistance R1, the second resistance R2, infrarede emitting diode D1 and the first triode Q1, first resistance R1 one end is as the input termination microprocessor of infrared transmitting circuit, the base stage Q1 of another termination first triode, the grounded emitter of the first triode Q1, collector is connected and is connect the negative pole of infrarede emitting diode D1 after the second resistance R2, and the positive pole of infrarede emitting diode D1 connects DC power supply.In the present embodiment, the positive pole of infrarede emitting diode D1 connects the VBUS power pins of OTG interface.Mobile terminal as while main frame sending controling instruction to infrared transmitting circuit for infrared transmitting circuit provides the DC power supply of 5V.Described infrared transmitter does not need built-in power, and therefore the volume of infrared transmitter is little, is connected easy to use with mobile terminal.
As shown in Figure 3, the OTG interface of the described infrared transmitter based on OTG interface is mini B socket, and mini B socket is connected with the mini A socket of smart mobile phone, and described infrared transmitter carries out signal by infrared signal and infrared remote control equipment and is connected.Described infrared remote control equipment comprises the household electrical appliance that TV, refrigerator, micro-wave oven etc. are provided with infrared remote receiver.After described infrared remote receiver is connected with smart mobile phone, user, by the corresponding APP of operative intelligence mobile phone, inputs corresponding steering order; Corresponding steering order is transferred to its mini A socket by smart mobile phone, steering order is transferred to the mini B socket of infrared transmitter by mini A socket, received steering order is transferred to microprocessor by mini B socket, steering order is forwarded to infrared transmitting circuit and sends by described microprocessor, realizes the control to infrared remote control equipment.Infrared transmitter is connected with mobile terminal and uses the household electrical appliance realized being provided with infrared remote receiver to carry out centralized control, easy to use.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
