Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a multimedia wireless transmission technology.
Background
Bluetooth is a wireless technology standard, and can realize short-distance data exchange among fixed equipment, mobile equipment and building personal area networks, and the Bluetooth is communicated by using UHF radio waves of an ISM wave band of 2.4-2.485 GHz. The Bluetooth can be connected with a plurality of devices, so that the difficulty of data synchronization is overcome. Bluetooth communication has no limitation of transmission angle, can communicate through any angle, and is more free in use. Because of the technical characteristics of Bluetooth, the Bluetooth wireless communication system is widely applied to the fields of televisions, set top boxes, conference systems and other equipment needing remote control. However, bluetooth pairing is cumbersome, and it is particularly difficult to pair when there are multiple bluetooth devices in the same environment. Under the condition of automatic pairing in the product, mispairing is easy to cause, and great trouble is caused to the use of users.
Infrared communication is a communication method for transmitting information by using infrared rays. Information such as language, words, data, images, etc. can be transmitted. The transmission angle is limited. The infrared remote control equipment has the advantages of large capacity, high confidentiality, good electromagnetic interference resistance, simple structure, small volume, light weight, low price and the like. The remote control scheme in the market at present mostly adopts an infrared mode, has low cost, and can be directly used without pairing, so that the remote control scheme is adopted by a large number of manufacturers. However, due to the limited transmission angle, the infrared remote control must be aimed at the direction of the device to be used. And the infrared rays are easily reflected by the wall surface, so that the problem that the remote controller operates other devices by mistake easily occurs when a plurality of receiving devices exist.
The existing remote controller technical scheme generally adopts a mode of independent infrared or independent Bluetooth remote control, even if Bluetooth and infrared remote control are integrated, infrared is only used as a signal for triggering Bluetooth pairing at most, bluetooth searching pairing is carried out when the signal is triggered, and correct equipment is screened to be paired and connected through the signal intensity of Bluetooth equipment.
As shown in fig. 1, the bluetooth remote controller wants to use the device B, and the pairing operation before the use of the conventional bluetooth remote controller is complex, and the first step is: the broadcast mode of the remote control is turned on. And a second step of: the device B searches for the bluetooth remote controller, and the user needs to know the name of the remote controller, and may search for a plurality of devices at this time, which is complicated for the novice user to use. And a third step of: after searching, pairing is started, if the second step takes too long, the remote controller can close the broadcasting mode to save electric quantity, and pairing failure is easy to cause. The conventional infrared remote controller does not use bluetooth, and is easily mishandled, as in the above figures, if it is desired to use the device B, it is easily handled to the device E. The advantage of infrared and bluetooth is combined to our mode, uses infrared help bluetooth to pair fast, and the user is simple and convenient to use, need not pay attention to the loaded down with trivial details of bluetooth pairing again.
Although the conventional Bluetooth pairing technology solves the problem of the success rate of Bluetooth pairing to a certain extent, when a plurality of Bluetooth devices are in a pairable mode and the signal strengths are similar, the probability of pairing to the wrong device can still occur, and the scheme can be said to treat the symptoms without treating the root cause. Once the user has paired the wrong device, it becomes very difficult to unpair the correct device.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The basic principle of the invention is as follows: the invention transmits the unique mark such as MAC address and the like to the equipment host through the infrared of the remote controller, and the equipment host performs identity information matching on the scanned terminal Bluetooth equipment according to the infrared received identity information, thereby selecting the unique Bluetooth equipment for Bluetooth pairing connection.
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. It should be further noted that, for convenience of description, only some, but not all, of the procedures/structures related to the present invention are shown in the drawings.
In a specific embodiment of the present invention, the flow between the remote controller and the device host is as follows:
step 110, the remote controller triggers the work by means of keys such as a combination key and the like, reads the MAC address information of the remote controller and transmits the MAC address information outwards through infrared.
The information sent by the infrared key comprises a manufacturer code and a key value. After triggering the combination key, the remote controller reads the MAC address information of the remote controller and continuously sends 6 key values.
In addition, the MAC address is typically 12 bits, and should be 12 key values to be sent. Each key consists of a manufacturer code + key, the key range is 0x2a0-0x2af, and one bit in the last bit code MAC address.
In the embodiment of the invention, since the first 6 bits of the MAC address of the device are fixed, only the last 6 bits are required to be transmitted. In addition, only 6 bits are transmitted, so that time required for transmitting the MAC address can be saved.
Step 120: after the MAC of the remote controller is transmitted by infrared, the Bluetooth module is started, the Bluetooth module is controlled to transmit Bluetooth broadcasting, and the Bluetooth module is set to be in a paired state.
In practical application, the infrared transmission MAC information and the Bluetooth broadcasting do not interfere with each other because of dual modes. The Bluetooth and infrared have no great influence on functions simultaneously and successively, and the Bluetooth and infrared can be set according to actual needs.
Step 130: if the remote control is already paired with other equipment hosts, the last pairing is canceled, and the pairing information is cleared.
Step 140: and the equipment host checks the integrity of the MAC address through the MAC address information sent by the infrared receiving remote controller, and confirms whether the MAC is a specific equipment or not.
At this time, if the received key information judges that the key value range is within 0x2a0-0x2af and the key value has an authenticatable manufacturer code, the received key information is considered as the MAC information sent by the remote controller, and the last bit of each key value with the same mark is stored. After 6 key values are stored, key value information is combined into an MAC address and sent to the Bluetooth service.
After receiving the MAC address information, the Bluetooth service transmits the MAC address to the responsible Bluetooth pairing process. The Bluetooth pairing process is responsible for checking and judging the MAC information.
Step 150: if the device host has pairing information, the last pairing is canceled.
Step 160: after the MAC address is confirmed, searching for the Bluetooth device is started, and whether the MAC address carried by the searched Bluetooth device is consistent with the received MAC address is compared one by one.
Step 170: if the MAC addresses are consistent, pairing operation is started to the Bluetooth equipment, namely the remote controller, and the Bluetooth equipment can be normally used after successful pairing.
Fig. 2 is a flowchart of a remote controller slave-side quick pairing according to an embodiment of the invention. As shown in the figure, the whole pairing process from the remote controller side, that is, the machine side, includes the following operation steps:
step S210: and the remote controller presses a combination key such as ok+5 to send infrared information, the MAC address carrying Bluetooth is sent to the device host to be paired, and Bluetooth enters a broadcast pairing mode, so that the device host can search and can be paired.
Step S220: and after the service life of the slave computer of the remote controller is ended, waiting for Bluetooth pairing of the host computer of the equipment.
Step S230: if the device host does not receive the infrared information, the pairing fails, and the user may start to repeat the process from step S110.
Step S240: after receiving the Bluetooth pairing starting information of the equipment host end, the remote controller automatically receives a request and starts pairing.
Step S250: after successful pairing, the device starts to wait for the connection of the host end of the device to Bluetooth, and is used for transmitting Bluetooth key events. At this time, if an uncertain accident such as power failure occurs in the remote controller, the his connection may fail, and the user may repeat the above steps to restart.
Step S260: after the connection is successful, the whole process is ended.
Fig. 3 is a flowchart of a fast pairing procedure at the host end of the device according to an embodiment of the invention. As can be seen from the figure, the device host quick pairing process mainly includes the following operations:
step S310: the infrared receiver at the host end of the device receives the signal and contains the complete bluetooth MAC address, at which time a search for bluetooth devices with the specific MAC just transmitted is started. External factors may cause that the desired device is not searched at this time, such as the remote control is powered off, or the remote control is out of range. In this case, the user needs to re-pair after the search times out. If the device is normally searched, starting the next flow.
Step S320: now that the device to be paired has been determined, it is necessary to first determine whether this device has been paired before. If the equipment is already paired, the pairing record of the equipment needs to be canceled; after the pairing is canceled, the state of pairing is entered; now in the unpaired state, pairing can begin.
Step S330: and after the pairing is successful, starting to connect with Bluetooth, and transmitting the Bluetooth key event. At this time, if an uncertain accident such as power failure occurs to the remote controller, the connection may fail, and the user may repeat the above steps to restart; the connection is automatically started.
Step S330: after the connection is successful, the whole process is ended.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described, but is capable of numerous modifications, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, while the invention has been described in connection with the above embodiments, the invention is not limited to the embodiments, but may be embodied in many other equivalent forms without departing from the spirit or scope of the invention, which is set forth in the following claims.
