Specifically, the wireless module 13 and the wireless array antenna 15 can be connected or disconnected through multiple sets of switches; each set of switches can be controlled by the processor 11, and different switches can correspond to antennas in different transmitting directions. The processor 11 may be a microprocessor (Microcontroller Unit, MCU). When the processor is running, it can make the wireless routing device 100 execute a control method of the wireless routing device 100 in the present invention. The method and device of the present invention will be described and illustrated in detail below through subsequent embodiments.

[0042] See Figure 4 , another embodiment of the present invention provides a flow chart of a method for controlling a wireless routing device, the method comprising:

[0043] Step S10: receiving the positioning data of the Bluetooth broadcast of the terminal device;

[0044] Step S20: Obtain the target direction where the terminal device is located according to the positioning data received by the Bluetooth array antenna; wherein, the target direction is the direction of the terminal device relative to the wireless routing device;

[0045] Step S30: Adjust the signal transmitting direction of the wireless array antenna according to the target direction.

[0046] In this embodiment, through steps S10-30, the positioning data broadcast by the Bluetooth of the terminal device is received, thereby identifying the target direction where the terminal device is located; then, the signal transmission direction of the wireless array antenna is adjusted according to the target direction, so that the wireless routing The device realizes directional routing, which reduces the power loss and radiation in the direction of the non-terminal device, improves the effective utilization of the antenna transmission power, and also improves the anti-interference ability between the wireless routing device and the terminal device. Each of the steps in this embodiment will be further elaborated and described below.

[0047] Step S10: receiving the positioning data of the Bluetooth broadcast of the terminal device.

[0048] In step S10, for the Bluetooth of the terminal device, it can continuously broadcast positioning data to the outside under a preset program. The positioning data may include one or more of the following, bluetooth device name, bluetooth address, broadcast channel and so on. The Bluetooth in the wireless routing device should be a Bluetooth version that supports AOA (Angle of Arrive, Angle of Arrival) positioning technology. For example, the Bluetooth in the wireless routing device can realize the direction-finding function for the terminal device based on the Bluetooth 5.1 protocol. The monitoring method for terminal equipment can be real-time monitoring with a very short interval, or periodic monitoring, for example, the period can be 20ms, 100ms, 1s, 5s and so on.

[0049] Step S20: Obtain a target direction where the terminal device is located 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.

[0050] In step S20, after the Bluetooth array antenna receives the corresponding positioning data, it calculates the angle of arrival corresponding to the positioning data according to the phase difference of signals received by different antennas, thereby analyzing the target direction where the terminal device is located. For example, when the number of Bluetooth array antennas is more than 3, the corresponding angle of arrival can be obtained for any two Bluetooth antennas, and then the mean value obtained by averaging all the angles of arrival can be used as the final angle of arrival to improve the orientation. accuracy. For example, when there are 4 Bluetooth antennas, they are blue antenna 1, antenna 2, antenna 3, and antenna 4; antenna 1 and antenna 2, antenna 1 and antenna 3, antenna 1 and antenna 4, antenna 2 and antenna 3 , Antenna 2 and Antenna 4, and Antenna 3 and Antenna 4 are respectively calculated to obtain 6 arrival angles, and then the mean value of the 6 arrival angles is calculated as the final arrival angle.

[0051] In this embodiment, the final angle of arrival may be directly used as the target direction of the terminal device. In addition, after obtaining the angle of arrival corresponding to the positioning data, an angle range can be determined as the target direction based on the angle of arrival; this method can avoid errors in positioning accuracy from causing the signal emitted by the finally activated wireless array antenna to Not enough to cover the terminal equipment corresponding to the angle of arrival. Further, in this embodiment, the target direction can be a range interval [α-β, α+β], where α represents the angle of arrival, and β is the compensation angle; that is, based on the target direction and the preset compensation angle, the upper range can be obtained. The limit value and the lower limit value of the range, the range interval can be obtained according to the upper limit value of the range and the lower limit value of the range. In this embodiment, β may be 5°-12°. If β is too large, it is not conducive to energy saving and directional signal transmission of the wireless routing device, and if β is too small, there will be a risk that the terminal device cannot be covered. When β can take a value of 6°-8°, for example, 7°, a better balance can be achieved.

[0052] Furthermore, in the process of obtaining the target direction, the terminal device can also be identified, so as to determine whether the currently monitored terminal device is registered in the wireless routing device; ensure that the subsequent processing and calculation of the wireless routing device are all for registered devices Processing calculations, saving computing resources; especially suitable for complex environmental conditions, such as office buildings, shopping malls and other environments. The specific identification steps are as follows:

[0053] First, according to the positioning data, the identification information of the terminal device is obtained; the identification information may be a Bluetooth address or other unique numbers used to mark the terminal device. Then, according to the identification information, it is judged whether the terminal device is registered in the wireless routing device; if the terminal device has been registered in the wireless routing device, it means that the terminal device needs to connect to the wireless routing device; positioning data to obtain the target direction where the terminal device is located. If the terminal device is not registered in the wireless routing device, it means that the terminal device may only be a device without connection requirements in a complex environment, and then continue to receive the positioning data of the Bluetooth broadcast of the terminal device.

[0054] Step S30: Adjust the signal transmitting direction of the wireless array antenna according to the target direction.

[0055] In step S30, the target antenna in the wireless array antenna can be determined according to the target direction; the target antenna in the wireless array antenna is turned on; wherein, the target antenna is an antenna that is not turned on in the target direction, and after the target antenna is turned on, the wireless routing device The signal emission direction covers the target direction. If there is already a connected device in the target direction before the current terminal device is detected, it means that the corresponding antenna in the target direction is already in the on state, and it only needs to keep the on state at this time. The signal transmission direction of the target antenna covers the target direction, that is, the range of the signal transmission direction can be larger than the range of the target direction; it can also coincide with the range of the target direction to ensure that the terminal device can be effectively and stably connected to the wireless routing device.

[0056] In some embodiments, after step S30, by judging the position and direction of the connected device, some antennas on the wireless routing device may be turned off to improve the efficiency of transmitting power and reduce radiation. Specifically, the location directions of all connected devices on the current wireless routing device may be obtained first; the location directions may be obtained by referring to the above-mentioned acquisition process of the target directions, which will not be repeated here. Then, according to the location direction corresponding to each connected device, the first direction coverage is determined; all connected devices are covered within the first direction coverage. Finally, turn off the antennas outside the coverage range of the first direction among the wireless array antennas. In this way, the radiation level of the wireless routing equipment is significantly reduced, and at the same time, the utilization rate of the existing transmission power is higher, the link distance is increased, and the power consumption is reduced, such as Figure 5 shown.

[0057] For example, in a home application scenario, the wireless routing device is installed in the living room, and multiple bedrooms and kitchens are distributed on both sides of the living room. When the user is active at home, the terminal device connected to the wireless routing device may only be the user's mobile phone. Activities in one bedroom may also be in the kitchen; at this time, the user is only in the room on one side of the living room (the mobile phone is also carried by the user), and the other room will have no terminal equipment connection. At this time, the coverage of the first direction will not include this direction, and the antenna in this direction can be turned off to reduce the overall radiation level of the wireless routing device, while saving power consumption and being more environmentally friendly.

[0058] Further, in the home application scenario, fixed devices and non-fixed devices can also be identified by changing the Bluetooth signal strength of the connected devices and/or the change of the angle of arrival of the connected devices; to filter out which connected devices are fixed devices and which The connected device is a mobile device; specifically, if the position direction (ie angle of arrival) and/or Bluetooth signal strength of the connected device does not change within a long first preset period, it can be determined as a fixed device, otherwise It is a mobile device; for example, the first preset time period can be 3 hours, 5 hours, 24 hours, etc.; the fixed device is generally a smart home appliance in a home, such as a dishwasher, a desk lamp, an air conditioner, and the like. Then, exclude fixed devices, and obtain the position and direction of all connected mobile devices on the current wireless routing device; determine the coverage of the second direction according to the position and direction of each mobile device; finally, turn off the coverage of the second direction in the wireless array antenna outside the antenna. Since most of these fixed devices are smart home devices, large bandwidth is not required for data transmission; multiple reflections of reliable wireless signals can also provide a relatively stable connection.

[0059] Further, after the fixed devices are screened out, the uplink and downlink traffic of the fixed devices can also be monitored to identify devices with small traffic in the fixed devices. Specifically, for any fixed device, when the sum of the average uplink traffic and downlink traffic within the second preset period is less than a preset traffic threshold, the fixed device may be determined to be a low-traffic device. The first preset time period can be 30 minutes, 1 hour, 10 hours, 24 hours, etc., and can be adjusted based on actual conditions. More preferably, the first preset time period can be 24 hours. The value of the traffic threshold is not limited, for example, it can be less than 50kb/s, 5kb/s, 10kb/s, 15kb/s, etc., without limitation. Then, obtain the location and direction of all connected mobile devices and large-traffic fixed devices on the current wireless routing device; determine the coverage of the third direction according to the location and direction of each mobile device and each large-traffic fixed device; finally, turn off the wireless Antennas outside the coverage of the third direction in the array antenna. This avoids affecting the wireless network connection of the home server, such as a wireless home NAS (Network Attached Storage, network attached storage) and other fixed devices with large traffic. More precise directional control is possible.

[0060] In addition, in some implementation manners, the antenna transmit power may also be adjusted. Specifically, after step S30, the antenna transmission power adjustment is also included, as follows:

[0061] First, obtain the Bluetooth signal strength corresponding to the positioning data; then, according to the Bluetooth signal strength, adjust the signal transmission power of the wireless array antenna within the preset signal strength range; wherein, the smaller the Bluetooth signal strength, the greater the signal transmission power; that is Bluetooth signal strength is inversely related to signal transmission power. The relationship between Bluetooth signal strength and signal transmission power can be tested and calibrated according to different products within the preset signal strength range. In this way, the efficiency of the signal power of the wireless routing device can be further ensured through the control of the signal strength, and the stable connection of the terminal device can be ensured.

[0062]Further, in order to avoid other connected devices being affected by 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 can also be judged, specifically: the terminal device can be judged Whether the Bluetooth signal strength is the minimum, if so, adjust the signal transmission power of the wireless array antenna within the preset signal strength range according to the Bluetooth signal strength; if not, do not adjust. In addition, the minimum value of the Bluetooth signal strength can also be obtained from the currently connected devices of the wireless routing device; then, according to the minimum value of the Bluetooth signal strength, the signal transmission power of the wireless array antenna is adjusted within a preset signal strength range. This ensures that the connected device with the weakest connection remains connected over the maximum distance.

[0063] To sum up, the method for controlling a wireless routing device provided in this embodiment recognizes the target direction of the terminal device by receiving the positioning data broadcast by the Bluetooth of the terminal device; then, adjusts the wireless array according to the target direction The signal transmission direction of the antenna enables the wireless routing device to achieve directional routing, reduces the power loss and radiation in the direction of no terminal equipment, improves the effective utilization of the antenna transmission power, and also improves the connection between the wireless routing device and the terminal device. anti-interference ability.
