Abstract
The utility model discloses a Bluetooth remote controller, aims at solving the technical problems for avoiding the interference among household electric appliances when receiving remote control signals and operating the household electric appliances in any direction by the remote controller, and adopts the following technical proposal: the Bluetooth remote controller comprises a microcontroller, an emitting antenna and a Bluetooth module that is connected between the microcontroller and the emitting antenna. Compared with the prior art, the Bluetooth remote controller realizes remote control of the household electric appliances by applying the Bluetooth technique as a wireless communication method, and consequently has long transmission distance and non-directivity, prevents the mutual control interference among various household electric appliances, and truly realizes the one-to-one remote control operation of the household electric appliances.
Description
Technical field
The utility model relates to the telepilot of a kind of controller of household electrical appliance, particularly a kind of household electrical appliance.
Background technology
The televisor of prior art or the telepilot of other household electrical appliance generally all adopt Infrared remote controller, and the deficiency that Infrared Transmission exists is: transmission range is short, has directivity, is subject to disturb., when using common infrared television set remote-controller, telepilot must be faced the infrared remote control receiver of televisor, otherwise influence the transmission of infrared signal as us, can not carry out straighforward operation.And when many TVs were done demonstration, telepilot interfered with adjacent TV easily.
Summary of the invention
The purpose of this utility model provides a kind of blue Tooth remote controller, and the technical matters that solve is to be interfered when avoiding household electrical appliance to accept remote signal, and telepilot can be controlled household electrical appliance with any direction.
The utility model is by the following technical solutions: a kind of blue Tooth remote controller, have microcontroller and emitting antenna, and be connected with bluetooth module between described microcontroller and the emitting antenna.
Connect by serial ports between microcontroller of the present utility model and the bluetooth module.
Microcontroller of the present utility model connects the push-button array sweep circuit.
Blue Tooth remote controller of the present utility model and controlled main frame are by the Bluetooth technology wireless connections.
Controlled main frame of the present utility model is provided with receiving antenna, bluetooth module and the host microcontroller that is linked in sequence.
The bluetooth module of controlled main frame of the present utility model is connected by serial ports with host microcontroller.
Bluetooth module of the present utility model adopts the SPP agreement.
Microcontroller MCU of the present utility model adopts P89LPC21.
The utility model compared with prior art, applying Bluetooth is realized remote control home appliance as the means of radio communication, has long transmission distance, and is non-directional, controlling of each household electrical appliance is interference-free, really realizes household appliance remote control operation one to one.
Description of drawings
Fig. 1 is the circuit block diagram of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.As shown in Figure 1, blue Tooth remote controller of the present utility model comprises microcontroller MCU, and microcontroller is connected with the push-button array sweep circuit with bluetooth module respectively, and microcontroller and bluetooth module transmit data by serial ports, bluetooth module connects emitting antenna, and battery is microcontroller and bluetooth module power supply.Telepilot and television main are by the Bluetooth technology wireless connections.Television main is provided with receiving antenna, bluetooth module and the main MCU that is linked in sequence.
As most preferred embodiment, telepilot of the present utility model is a TV remote controller, and microcontroller MCU adopts P89LPC21, and bluetooth module has the spp host-host protocol.
Workflow of the present utility model is as follows, MCU scans push-button array, obtain pressing the signal of key, encode then, the telepilot of different manufacturers has different codings, press as key 1, MCU promptly provides the coding key assignments of key 1, it is sent to bluetooth module by serial communication, bluetooth module sends to the television main receiving antenna by emitting antenna with the key assignments signal, be connected with receiving antenna bluetooth module receive the key assignments signal after, key assignments is offered the host microcontroller MCU of television main by serial communication, main MCU decodes, and according to the content of operation of key assignments televisor is controlled.
Telepilot of the present utility model is to the key scan data, and the back of encoding is by serial ports transmission data, and the bluetooth packing sends, with digital form transmission remote control control signal, can realize low error rate, accurately control different household electrical appliance, realize household appliance remote control operation one to one.
