The embodiment of the invention provides a control method and a control device of wireless routing equipment, which can be applied to directional signal emission control of the wireless routing equipment. The wireless routing device in this embodiment is at least provided with a bluetooth array antenna and a wireless array antenna, and the wireless routing device includes, but is not limited to, a router, and other devices with a WIFI (wireless network communication technology) routing function, such as a mobile phone, a computer, and the like. In this embodiment, the number of the antennas of the bluetooth array antenna and the number of the antennas of the wireless array antenna are at least two or more, so as to ensure that the bluetooth direction finding function is realized and the wireless signal direction routing is realized.
Referring to fig. 3, an embodiment of the present invention provides a wireless routing device 100, where the wireless routing device 100 includes a processor 11, a bluetooth module 12, and a wireless module 13, the bluetooth module 12 and the wireless module 13 are both in communication connection with the processor 11 and controlled by the processor 11, the bluetooth module 12 is connected to a bluetooth array antenna 14, and the wireless module 13 is connected to a wireless array antenna 15; signals received by the bluetooth module 12 and the wireless module 13 through the antenna may be subjected to preliminary processing, such as signal amplification, by a front-end module 16. The wireless array antenna 15 has a plurality of directional transmitting directions, and the wireless array antenna 15 can be controlled to transmit signals in a specific direction according to different requirements. Specifically, the wireless module 13 and the wireless array antenna 15 can be connected or disconnected through a plurality of groups of switches; each set of switches may be controlled by the processor 11 and different switches may correspond to antennas in different transmit directions. The processor 11 may be a Microprocessor (MCU). The processor, when executed, may cause the wireless routing device 100 to perform a method of controlling the wireless routing device 100 in the present invention. The process and apparatus of the present invention will now be illustrated and described in detail by the examples which follow.
Referring to fig. 4, another embodiment of the present invention provides a flowchart of a method for controlling a wireless routing device, where the method includes:
step S10: receiving positioning data broadcasted by the Bluetooth of the terminal equipment;
step S20: acquiring a target direction of the terminal equipment according to the positioning data received by the Bluetooth array antenna; wherein the target direction is a direction of the terminal device relative to the wireless routing device;
step S30: and adjusting the signal transmitting direction of the wireless array antenna according to the target direction.
In the embodiment, through steps S10-30, positioning data broadcast by the bluetooth of the terminal device is received, so as to identify the target direction in which the terminal device is located; then, the signal transmitting direction of the wireless array antenna is adjusted according to the target direction, so that the wireless routing equipment realizes directional routing, the power loss and radiation in the direction without the terminal equipment are reduced, the effective utilization rate of the transmitting power of the antenna is improved, and the anti-interference capability between the wireless routing equipment and the terminal equipment is also improved. The steps in this example are further illustrated and described, respectively.
Step S10: and receiving the positioning data broadcasted by the Bluetooth of the terminal equipment.
In step S10, for the bluetooth of the terminal device, it may continuously broadcast the positioning data to the outside under a preset program. The location data may include one or more of a bluetooth device name, a bluetooth address, a broadcast channel, and the like. The bluetooth in the wireless routing device should be a bluetooth version supporting AOA (Angle of arrival) positioning technology, for example, the bluetooth in the wireless routing device may implement a direction-finding function for the terminal device based on the bluetooth 5.1 protocol. The monitoring mode of the terminal device may be real-time monitoring with an extremely short interval time, or may be periodic monitoring, for example, the period may be 20ms, 100ms, 1s, 5s, and so on.
Step S20: acquiring a target direction of the terminal equipment according to the positioning data received by the Bluetooth array antenna; wherein the target direction is a direction of the terminal device relative to the wireless routing device.
In step S20, after the bluetooth array antenna receives the corresponding positioning data, the arrival angle corresponding to the positioning data is calculated according to the phase difference between the signals received by the different antennas, so as to resolve the target direction of the terminal device. For example, when the number of the bluetooth array antennas is more than 3, the corresponding arrival angles can be obtained for every two arbitrary bluetooth antennas, and then the average value obtained by averaging all the arrival angles is used as the arrival angle finally used, so that the accuracy of the orientation is improved. For example, when there are 4 bluetooth antennas, there are a blue antenna 1, an antenna 2, an antenna 3, and an antenna 4; respectively calculating 6 arrival angles for an antenna 1 and an antenna 2, an antenna 1 and an antenna 3, an antenna 1 and an antenna 4, an antenna 2 and an antenna 3, an antenna 2 and an antenna 4, and an antenna 3 and an antenna 4, and then calculating the average value of the 6 arrival angles as the finally used arrival angle.
In this embodiment, the finally used arrival angle may be directly adopted as the target direction of the terminal device. In addition, after the arrival angle corresponding to the positioning data is obtained, an angle range can be determined as a target direction based on the arrival angle; by adopting the method, the situation that the finally started signals transmitted by the wireless array antenna are insufficient to cover the terminal equipment corresponding to the arrival angle due to the error of the positioning precision can be avoided. Further, in this embodiment, the target direction may be a range interval [ α - β, α + β ], where α represents the arrival angle, and β is the compensation angle; that is, the range upper limit value and the range lower limit value are obtained based on the target direction and the preset compensation angle, and the range section can be obtained according to the range upper limit value and the range lower limit value. In the embodiment, the beta can be 5-12 degrees, the overlarge beta is not beneficial to energy saving and directional signal transmission of the wireless routing equipment, and the risk that the terminal equipment cannot be covered due to the overlarge beta can be generated. When the beta can be 6-8 degrees, for example, 7 degrees, better balance can be realized.
Furthermore, the terminal equipment can be identified in the process of obtaining the target direction, so that whether the currently monitored terminal equipment is registered in the wireless routing equipment is determined; the subsequent processing calculation of the wireless routing equipment is guaranteed to be the processing calculation aiming at the registered equipment, so that the calculation resource is saved; the device is particularly suitable for complex environment working conditions, such as environments of office buildings, shopping malls and the like. The specific identification steps are as follows:
firstly, acquiring identification information of the terminal equipment according to the positioning data; the identification information may be a bluetooth address or other unique number used to tag the terminal device. Then, judging whether the terminal equipment is registered in the wireless routing equipment or not according to the identification information; if the terminal equipment is registered in the wireless routing equipment, the terminal equipment is indicated to have the requirement of connecting the wireless routing equipment; at this time, the target direction of the terminal device can be obtained according to the positioning data received by the bluetooth array antenna. If the terminal device is not registered in the wireless routing device, which indicates that the terminal device may be only a device without a connection requirement in a complex environment, the positioning data of the bluetooth broadcast of the terminal device can be continuously received.
Step S30: and adjusting the signal transmitting direction of the wireless array antenna according to the target direction.
In step S30, a target antenna of the wireless array antenna may be determined according to the target direction; starting a target antenna in the wireless array antenna; the target antenna is an antenna which is not started in the target direction, and after the target antenna is started, the signal transmitting direction of the wireless routing equipment covers the target direction. If there is a connected device in the target direction before the current terminal device is detected, it indicates that the antenna corresponding to the target direction is already in the on state, and at this time, the on state is maintained. The signal transmitting direction of the target antenna covers the target direction, namely the range of the signal transmitting direction can be larger than the range of the target direction; the range of the wireless router can be overlapped with that of the target direction, and the terminal equipment can be effectively and stably connected with the wireless router.
In some embodiments, after step S30, part of the antennas on the wireless routing device may be turned off to improve the efficiency of the transmission power and reduce the radiation by determining the location and direction of the connected device. Specifically, the position directions of all connected devices on the current wireless routing device can be obtained first; the position and direction can be obtained by referring to the above-mentioned obtaining process of the target direction, and details are not repeated. Then, determining a first direction coverage range according to the position direction corresponding to each connected device; all connected devices are covered in the first direction coverage. And finally, turning off the antennas out of the first direction coverage range in the wireless array antenna. Thus, the radiation level of the wireless routing device is remarkably reduced, the utilization rate of the existing transmission power is higher, the link distance is increased, and the power consumption is reduced, as shown in fig. 5.
For example, in a home application scenario, the wireless routing device is installed in a living room, and a plurality of bedrooms and kitchens are distributed on two sides of the living room, and when a user is in a home activity, a terminal device connected to the wireless routing device may only be a mobile phone of the user, and the user may be in any bedroom or kitchen; at this point, the user is only in the room on one side of the living room (the cell phone is also carried by the user), and the room on the other side will have no terminal device connected. The coverage range of the first direction does not include the direction, and the antenna in the direction can be closed, so that the overall radiation level of the wireless routing equipment is reduced, the power consumption is saved, and the wireless routing equipment is more environment-friendly.
Furthermore, in a home application scene, fixed equipment and non-fixed equipment can be identified through the change of the Bluetooth signal strength of the connected equipment and/or the change of the arrival angle of the connected equipment; to screen out which connected devices are fixed devices and which connected devices are mobile devices; specifically, if the position direction (i.e., the arrival angle) and/or the bluetooth signal strength of the connected device do not change within a first longer preset time period, the connected device may be determined as a fixed device, and otherwise, the connected device may be determined as a mobile device; for example, the first predetermined period of time may be 3 hours, 5 hours, 24 hours, etc.; the fixed devices are generally intelligent household appliances in the home, such as dishwashers, table lamps, air conditioners and the like. Then, removing the fixed equipment, and acquiring the position directions of all connected mobile equipment on the current wireless routing equipment; determining a second direction coverage range according to the position direction of each mobile device; and finally, turning off the antennas out of the coverage range of the second direction in the wireless array antenna. Because the fixed devices are mostly intelligent household devices, a large bandwidth is not needed for data transmission; multiple reflections of reliable wireless signals can also be connected more stably.
Furthermore, after the fixed equipment is screened out, the uplink and downlink flow of the fixed equipment can be monitored, and the small-flow equipment in the fixed equipment can be identified. Specifically, for any fixed device, when the sum of the average uplink traffic and the downlink traffic in the second preset time period is smaller than the preset traffic threshold, the fixed device may be determined to be a small-traffic device. The first predetermined period of time may be 30 minutes, 1 hour, 10 hours, 24 hours, etc., and may be adjusted based on the actual situation, and preferably, the first predetermined period of time may be 24 hours. The flow threshold value is not limited, and may be, for example, less than 50kb/s, 5kb/s, 10kb/s, 15kb/s, etc., without limitation. Then, acquiring the position directions of all connected mobile equipment and large-flow fixed equipment on the current wireless routing equipment; determining a third direction coverage range according to the position direction of each mobile device and each large-flow fixed device; and finally, turning off the antenna out of the third direction coverage range in the wireless array antenna. Therefore, wireless Network connection of large-flow fixed equipment such as a wireless home Attached Storage (NAS) and the like is prevented from being influenced. The directional control can be more accurately carried out.
In addition, in some embodiments, adjustment of the antenna transmit power may also be performed. Specifically, after step S30, the method further includes adjusting the antenna transmission power as follows:
firstly, acquiring the Bluetooth signal intensity corresponding to positioning data; then, according to the intensity of the Bluetooth signal, the signal transmitting power of the wireless array antenna is adjusted within a preset signal intensity range; the smaller the Bluetooth signal intensity is, the larger the signal transmitting power is; i.e., the bluetooth signal strength is inversely related to the signal transmission power. The relationship between the bluetooth signal strength and the signal transmitting power can be tested and calibrated within a preset signal strength range according to different products. Therefore, the efficiency of the signal power of the wireless routing equipment can be further ensured through the intensity control of the signal, and the stable connection of the terminal equipment is ensured.
Further, in order to avoid that other connected devices are affected due to the addition of a certain terminal device in the wireless routing device, the signal strength of the currently connected device of the wireless routing device may also be determined, specifically: the method can judge whether the Bluetooth signal intensity of the terminal equipment is minimum, if so, the signal transmitting power of the wireless array antenna is adjusted within a preset signal intensity range according to the Bluetooth signal intensity; if not, no adjustment is carried out. In addition, the minimum value of the Bluetooth signal intensity can be acquired from the current connected equipment of the wireless routing equipment; and then, according to the minimum value of the Bluetooth signal intensity, adjusting the signal transmitting power of the wireless array antenna within a preset signal intensity range. This ensures that the weakest connected device remains continuously connected over the maximum distance.
In summary, in the control method for the wireless routing device provided in this embodiment, the target direction in which the terminal device is located is identified by receiving the positioning data broadcast by the bluetooth of the terminal device; then, the signal transmitting direction of the wireless array antenna is adjusted according to the target direction, so that the wireless routing equipment realizes directional routing, the power loss and radiation in the direction without the terminal equipment are reduced, the effective utilization rate of the transmitting power of the antenna is improved, and the anti-interference capability between the wireless routing equipment and the terminal equipment is also improved.
