Description

Remote controller positioning method and system
Technical Field
The invention belongs to the field of remote controllers, and particularly relates to a remote controller positioning method and system.
Background
A remote control is a remote control device used to remotely control an apparatus. Television remote controls are common devices in daily life. From the signal classification of the remote controller, the television remote controller is mainly classified into the following three types: the infrared remote controller controls the television through infrared non-visible light. The remote controller can remotely control the television at a longer distance by changing infrared rays into digital signals which can be recognized by the television. But due to the limitation of infrared itself, infrared remote controls cannot pass through obstacles for remote control or remotely control equipment at a large angle. The infrared remote controller has low manufacturing cost and high stability, and does not need additional arrangement.
The 2.4GHz wireless remote controller, the core of 2.4G wireless remote controller is 2.4G wireless module. The remote control signal transmission mode successfully overcomes the defect of infrared remote control, and can remotely control the television at various angles indoors. Compared with a traditional infrared remote controller, the 2.4GHz wireless remote controller gets rid of the problem of directivity, and the remote controller can be used for operating equipment at any position and any angle in a room without worrying about the problem that the equipment cannot receive signals. In addition, the signal transmission bandwidth of 2.4GHz is larger, so that the remote controller is allowed to perform more complicated operations, such as voice and body sensing operations, and the experience of the remote controller is more excellent. However, 2.4GHz is not perfect, and since the WiFi signal used by us is also in the 2.4GHz band, in the case of many devices, the 2.4GHz device sometimes interferes with WiFi, thereby reducing the precision of remote control operation.
The Bluetooth remote controller utilizes the wireless Bluetooth technology to transmit data, and has the advantage that the Bluetooth remote controller is matched with a television to achieve a completely independent signal transmission channel, so that the interference between wireless signals of different devices is avoided. And because the Bluetooth signal transmission encryption is good, the user does not need to worry that the transmitted signal is acquired by other people. However, the convenience of the bluetooth remote controller is still to be further improved.

Briefly, bluetooth technology is a technology for transmitting data to each other between various 3C devices using low power radio. Bluetooth operates in the 2.4GHz ISM (i.e., Industrial, scientific, medical) band, which is common worldwide, using the IEEE802.11 protocol. As an emerging short-range wireless communication technology, the development of low-rate wireless personal area networks is being strongly driven.

The wireless frequency modulation layer is microwave which does not need authorization and passes through the 2.4GHz ISM frequency band, data stream transmission and filtering are realized on the wireless frequency modulation layer, and conditions which are required to be met by the normal work of the Bluetooth transceiver in the frequency band are mainly defined. Link management enables secure control of link establishment, connection and tear down.
2. An intermediate protocol layer.
The intermediate protocol layer in the Bluetooth technology system mainly comprises four parts of a service discovery protocol, a logic link control and adaptation protocol, a telephone communication protocol and a serial port simulation protocol. The role of the service discovery protocol layer is to provide a mechanism for upper layer applications to facilitate the use of services in the network. The logical link control and adaptation protocol is responsible for data disassembly and assembly, multiplexing protocol and controlling service quality, and is the basis for realizing the functions of other protocol layers.
3. And (4) high-level application.
In a bluetooth technology composition system, the higher layer application is the part of the framework that is located at the top of the protocol layer. The high-level application of the Bluetooth technology mainly comprises file transmission, network and local area network access. The heterogeneous high-level applications are a kind of wireless communication realized by a certain application mode through a corresponding application program.

The Bluetooth technology product is convenient to use, another Bluetooth technology product can be searched by utilizing the Bluetooth equipment, the contact between the two equipment is quickly established, and data can be automatically transmitted under the action of control software.
3. The Bluetooth technology has strong safety and anti-interference capability, and because the Bluetooth technology has a frequency hopping function, the ISM frequency band is effectively prevented from encountering an interference source. The compatibility of the bluetooth technology is good, and at present, the bluetooth technology can be developed into a technology independent of an operating system, so that good compatibility in various operating systems is realized.
4. The transmission distance is short: at present, the main working range of the bluetooth technology is about 10 meters, the bluetooth technology after increasing the radio frequency power can work within the range of 100 meters, and only then can the working quality and efficiency of the bluetooth during transmission be ensured, and the transmission speed of the bluetooth is improved. In addition, the interference between the technology and other electronic products can be effectively reduced in the connection process of the Bluetooth technology, so that the normal operation of the Bluetooth technology can be ensured. The Bluetooth technology not only has higher transmission quality and efficiency, but also has the characteristic of higher transmission safety.
5. Propagation by frequency modulated spread spectrum techniques: in the practical application period of the Bluetooth technology, the original frequency points can be divided and converted, if the Bluetooth technology with higher frequency hopping speed is adopted, the main unit in the whole Bluetooth system can be converted in an automatic frequency hopping mode, and therefore the Bluetooth technology can be subjected to frequency hopping randomly.
