Step A20, determining a target Bluetooth remote controller in the plurality of Bluetooth remote controllers according to the detected Bluetooth signal intensity of the plurality of Bluetooth remote controllers;
it should be noted that, when a plurality of display devices and a plurality of bluetooth remote controllers are adapted simultaneously on a production line, a production worker needs to place a target bluetooth remote controller paired with the display device at a position closest to a bluetooth module of the display device, that is, needs to place a target bluetooth remote controller paired with the display device at a position closest to the display device, so that the bluetooth remote controller with the strongest bluetooth signal intensity detected by the display device is the bluetooth remote controller closest to the display device, that is, the target bluetooth remote controller paired with the display device, that is, the bluetooth remote controller with the strongest bluetooth signal intensity is taken as the target bluetooth remote controller according to the detected bluetooth signal intensities of the plurality of bluetooth remote controllers.
Step A30, sending a connection request to the target Bluetooth remote controller, wherein the connection request carries a first power gear difference value of the target Bluetooth remote controller;
it can be understood that, a preset RPI (report power information) table is provided in the display device, the table has a preset RPI gear number and a corresponding RSSI (Received Signal Strength) value range, and a transmission power difference value between adjacent gears is preset, and a first power gear difference value of the target bluetooth remote controller can be determined according to the bluetooth Signal Strength RSSI value of the target bluetooth remote controller, the preset RPI table and a preset target power gear.
Optionally, the step of sending a connection request to the target bluetooth remote controller includes:
step B1, determining a first power gear difference value of a target Bluetooth remote controller according to the Bluetooth signal intensity of the target Bluetooth remote controller;
understandably, the bluetooth signal strength of the target bluetooth remote controller, that is, the RSSI value of the target bluetooth remote controller, can determine the first power gear difference value of the target bluetooth remote controller according to the RSSI value of the target bluetooth remote controller, the preset RPI table and the preset target power gear.
And B2, generating a connection request according to the first power gear difference value of the target Bluetooth remote controller.
After the first power gear difference value of the target Bluetooth remote controller is determined, a connection request carrying the first power gear difference value of the target Bluetooth remote controller can be generated.
The display device generates a connection request according to the determined first power gear difference value of the target Bluetooth remote controller, sends the connection request to the target Bluetooth remote controller so as to establish connection with the target Bluetooth remote controller, and requests the target Bluetooth remote controller to reduce the transmission power by carrying the first power gear difference value in the connection request so as to avoid interference on pairing of other display devices and the Bluetooth remote controller.
Optionally, the step of determining a first power step difference value of the target bluetooth remote controller according to the bluetooth signal strength of the target bluetooth remote controller includes:
step C1, determining a first initial power gear of the target Bluetooth remote controller according to the Bluetooth signal intensity of the target Bluetooth remote controller and a preset power information report table;
and step C2, determining a first power gear difference value of the target Bluetooth remote controller according to the first initial power gear and a preset target power gear.
It should be noted that, a preset RPI table is provided in the display device, where the table is provided with a RPI gear number and a corresponding RSSI value range, and a transmission power difference value between adjacent gears is preset, and a first initial power gear of the target bluetooth remote controller may be determined according to a bluetooth signal strength RSSI value of the target bluetooth remote controller and a preset power information report table, for example, referring to table 1-1 below, the RSSI specific range value in table 1-1 is only an example, and does not constitute a limitation to the RPI table, and other range values may be set according to a signal condition on a production line in practice.
Referring to the following table 1-1, according to the received bluetooth signal strength of the target bluetooth remote controller, if the RSSI value of the received target bluetooth remote controller is between-66 dBm and-62 dBm, the corresponding RPI gear number is 5, that is, the first initial power gear is 5, the display device needs the target bluetooth remote controller to reduce the transmission power, so that the RSSI value of the target bluetooth remote controller received by the display device is in the lowest receiving range adapted to bluetooth, for example, the lowest receiving range is-87 dBm and-82 dBm, the corresponding gear is 1, that is, the preset target power gear is 1, and the first power gear difference of the target bluetooth remote controller is calculated to be 5-1=4.
TABLE 1-1 RPI Power information report Table
| RPI (resilient packet infrastructure) codingNumber (C) | RSSI value (dBm) |
| 0 | Less than-87 |
| 1 | -87～-82 |
| 2 | -81～-77 |
| 3 | -78～-72 |
| 4 | -71～-67 |
| 5 | -66～-62 |
| 6 | -61～-57 |
| 7 | -56 or more |
Step A40, receiving a first response message fed back by a target Bluetooth remote controller based on a connection request, wherein the first response message carries a second power gear difference value of a display device;
it can be understood that the target bluetooth remote controller also has a preset RPI table, and the transmission power difference between adjacent gears is preset, and the transmission power difference between the RPI table in the target bluetooth remote controller and the transmission power difference between adjacent gears are the same as the transmission power difference between the RPI table in the display device and the adjacent gears.
After receiving a connection request sent by a display device, a target bluetooth remote controller similarly determines a second power gear difference value of the display device according to a bluetooth signal strength RSSI value of the display device, and the method for the target bluetooth remote controller to calculate the second power gear difference value is the same as the method for the display device to calculate the first power gear difference value, that is, first, according to the received bluetooth signal strength RSSI value of the display device and a preset RPI table, a second initial power gear of the display device is determined, according to the second initial power gear and the preset target power gear, a second power gear difference value of the display device is determined, and meanwhile, the target bluetooth remote controller determines a target transmission power value according to the first power gear difference value in the connection request, for example, if the transmission power difference value between adjacent gears is 1dBm and the first power gear difference value is 4, it is determined that the adjustment power of the target bluetooth remote controller is 4=4dbm, then, according to the current transmission power value, it is determined that the current transmission power is 8dBm, then the target transmission of the target bluetooth remote controller is 8-4=4dbm, and if the target bluetooth remote controller transmits a subsequent pairing message to the second transmission device, and responds to the target device, and then the target remote controller, and the target device, if the target remote controller transmits a subsequent target transmission power value is a subsequent pairing message that the second power value is reduced.
The connection request for reducing power is sent to the target Bluetooth remote controller in the early stage of pairing, and then the target Bluetooth remote controller sends the response message to the display device at the reduced target transmitting power value in the subsequent pairing process, so that the interference on pairing of other display devices and the Bluetooth remote controller can be reduced, and the pairing accuracy of the display device and the Bluetooth remote controller on the production line is further improved.
Step A50, determining a first target transmitting power of the display device according to the second power gear difference value;
optionally, the step of determining a first target transmission power of the display device according to the second power step difference value includes:
step D1, determining adjustment power according to the second power gear difference and a transmission power difference between preset adjacent gears;
it can be understood that after receiving a first response message sent by a target bluetooth remote controller, the display device can determine the adjustment power of the display device according to a second power gear difference value in the first response message and a transmission power difference value between preset adjacent gears; for example, if the second power step difference is 3 and the difference in transmit power between adjacent steps is 1dBm, the adjusted power is 3 × 1=3dBm.
And D2, determining the first target transmitting power of the display equipment according to the current transmitting power value and the adjusting power.
It can be understood that the first target transmission power of the display device can be determined according to the current transmission power value and the adjustment power, for example, if the current transmission power value is 8dBm and the adjustment power is 3dBm, the first target transmission power of the display device can be determined to be 8-3=5dBm.
In the early stage of pairing, the display device reduces the transmitting power according to the power gear difference value sent by the target Bluetooth remote controller, and in the subsequent pairing process, the display device sends a request and a response message to the target Bluetooth remote controller according to the reduced target transmitting power value, so that the interference on the pairing of other display devices and the Bluetooth remote controller can be reduced, and the pairing accuracy of the display device and the Bluetooth remote controller on a production line is further improved.
And step A60, sending a pairing request to the target Bluetooth remote controller according to the first target transmitting power so as to complete Bluetooth pairing between the display equipment and the target Bluetooth remote controller.
It should be noted that, after the first target transmission power is determined, the display device sends a pairing request to the target bluetooth remote controller at the first target transmission power value, and in the subsequent pairing process, the display device sends a request and a response message to the target bluetooth remote controller at the reduced first target transmission power value to complete the subsequent pairing, so that the interference on the pairing of other display devices and the bluetooth remote controller can be reduced, and the accuracy of the pairing of the display device and the bluetooth remote controller on the production line is further improved.
According to the invention, after the display equipment is started, a Bluetooth scanning function is started, and the Bluetooth signal intensity of the scanned Bluetooth remote controller is detected; determining a target Bluetooth remote controller in the plurality of Bluetooth remote controllers according to the detected Bluetooth signal intensity of the plurality of Bluetooth remote controllers; the method comprises the steps of sending a connection request with a first power gear difference value to a target Bluetooth remote controller, receiving a first response message fed back by the target Bluetooth remote controller based on the connection request, wherein the first response message carries a second power gear difference value, determining first target transmitting power by display equipment according to the second power gear difference value, sending a pairing request to the target Bluetooth remote controller by the first target transmitting power, and completing the subsequent pairing process. Through setting up signal strength detection mechanism and judgement mechanism at the display device end, display device can automatic selection with it mate the target bluetooth remote controller to after establishing the connection with the first target transmitting power after reducing to target bluetooth remote controller send the pairing request, accomplish the follow pairing process, reduced the interference that pairs in-process to other display device and bluetooth remote controller, thereby make on the production line can carry out the pairing of many display device and many bluetooth remote controllers simultaneously, and the problem of mismatching can not appear, adaptation efficiency is high, and production efficiency is improved.
Optionally, in step a20, the step of determining a target bluetooth remote controller among the plurality of bluetooth remote controllers according to the detected bluetooth signal strengths of the plurality of bluetooth remote controllers includes:
step A21, according to the detected Bluetooth signal intensity of the plurality of Bluetooth remote controllers, taking the Bluetooth remote controller with the strongest Bluetooth signal intensity as an alternative Bluetooth remote controller;
it can be understood that, because multiple display devices and multiple bluetooth remote controllers are adapted simultaneously, multiple bluetooth remote controllers scanned by the display devices may exist, the display devices may analyze Received beacon frames sent by the bluetooth remote controllers to obtain MAC addresses and RSSI (Received Signal Strength) values of the bluetooth remote controllers, the RSSI values of different bluetooth remote controllers are different due to different distances from the display devices, and the bluetooth remote controller with the strongest bluetooth Signal Strength can be determined according to the obtained RSSI values of the multiple bluetooth remote controllers and used as an alternative bluetooth remote controller.
Step A22, comparing the Bluetooth signal intensity of the alternative Bluetooth remote controller with a preset threshold value;
