The present invention also provides a Bluetooth batch pairing method. The execution subject of the present invention is a display device. Multiple groups of display devices and Bluetooth remote controllers on the production line can be paired in parallel, and each display device can independently operate the Bluetooth batch pairing method of the present invention. For example, the following describes the pairing process between a single display device and a Bluetooth remote control.

Referring to Fig. 2, the bluetooth batch pairing method of the present invention comprises:

Step A10, when the display device is turned on, start the bluetooth scanning function, and detect the bluetooth signal strength of each bluetooth remote controller scanned;

On the production line, after the display device is turned on, it will automatically enter the engineering mode and automatically enter the Bluetooth adaptation interface, and judge whether the display device has a paired Bluetooth remote control; The matching interface displays the address information of the historical bluetooth remote control that has been paired. The address information refers to the MAC (Media Access Control Address) address of the bluetooth remote control, and detects whether it has received the For the re-pairing command, the preset time period can be 10 seconds, 20 seconds, etc. If the re-pairing command is not received within the preset time period, the address information of the paired Bluetooth remote controller will continue to be displayed on the Bluetooth adaptation interface. If the re-pairing command is received within the set time period, the Bluetooth scanning function will be activated; if the display device has not been paired with the Bluetooth remote control before, the Bluetooth scanning function will be activated. Since there are multiple display devices and multiple Bluetooth remote controls on the production line at the same time Perform pairing, so after starting the Bluetooth scanning function, the display device can detect the Bluetooth signals of multiple Bluetooth remote controls.

Optionally, after the Bluetooth remote control is powered on for the first time, it will detect whether there is historical pairing information stored in the register. If there is historical pairing information, the production operator will identify whether it needs to be paired again. If it is detected that the production operator presses the Bluetooth remote control The re-pairing command triggered by the specified button on the device sends a beacon frame in the form of a broadcast packet. The beacon frame contains the MAC (Media Access Control Address, Media Access Control Address) address information of the Bluetooth remote control, so that the Bluetooth remote control In the state that can be scanned, if there is no historical pairing information, the operator does not need to press the designated button of the Bluetooth remote control, and directly sends the beacon frame in the form of a broadcast packet.

By presetting the matching program in the MCU (Microcontroller Unit, micro control unit) of the Bluetooth remote control, after the Bluetooth remote control is powered on for the first time, there is no need for the production operator to press the designated button, and the beacon frame is directly broadcast to make the Bluetooth remote control in a state where it can be used. The scanned status simplifies the operation of production workers and improves the matching efficiency.

Step A20, according to the detected Bluetooth signal strength of multiple Bluetooth remote controllers, determine the target Bluetooth remote controller among the multiple Bluetooth remote controllers;

It should be noted that when multiple display devices and multiple Bluetooth remote controllers are simultaneously adapted on the production line, the production operator needs to place the target Bluetooth remote controller paired with the display device at the nearest position to the Bluetooth module of the display device. That is, the target Bluetooth remote control paired with the display device needs to be placed at the nearest position to the display device, so that the Bluetooth remote control with the strongest Bluetooth signal strength detected by the display device is the Bluetooth remote control closest to the display device. The target Bluetooth remote controller paired with the display device, that is, according to the detected Bluetooth signal strengths of multiple Bluetooth remote controllers, the Bluetooth remote controller with the strongest Bluetooth signal strength is used as the target Bluetooth remote controller.

Step A30, sending a connection request to the target Bluetooth remote controller, the connection request carrying the first power level difference of the target Bluetooth remote controller;

It is understandable that there is a preset RPI (report power information, power information report) table in the display device, and there are preset RPI gear numbers and corresponding RSSI (Received Signal Strength Indication, received signal strength) value ranges in the table , and preset the transmission power difference between adjacent gears, according to the Bluetooth signal strength RSSI value of the target Bluetooth remote controller, the preset RPI table and the preset target power gear, the first position of the target Bluetooth remote controller can be determined. power level difference.

Optionally, before the step of sending a connection request to the target Bluetooth remote controller includes:

Step B1, according to the Bluetooth signal strength of the target Bluetooth remote control, determine the first power level difference of the target Bluetooth remote control;

It is understandable that the Bluetooth signal strength of the target Bluetooth remote control, that is, the RSSI value of the target Bluetooth remote control, can be determined according to the RSSI value of the target Bluetooth remote control, the preset RPI table, and the preset target power level. The difference value of the first power level of the remote control.

Step B2, generating a connection request according to the first power level difference of the target Bluetooth remote controller.

After the first power level difference of the target Bluetooth remote controller is determined, a connection request carrying the first power level difference of the target Bluetooth remote controller can be generated.

The display device generates a connection request according to the determined first power level difference of the target Bluetooth remote controller, and sends a connection request to the target Bluetooth remote controller to establish a connection with the target Bluetooth remote controller, and carries the first power level in the connection request Gear difference, request the target Bluetooth remote control to reduce the transmission power, so as not to interfere with the pairing of other display devices with the Bluetooth remote control.

Optionally, the step of determining the first power level difference of the target Bluetooth remote controller according to the Bluetooth signal strength of the target Bluetooth remote controller includes:

Step C1, according to the Bluetooth signal strength of the target Bluetooth remote controller and the preset power information report table, determine the first initial power level of the target Bluetooth remote controller;

Step C2, determining the first power level difference of the target Bluetooth remote controller according to the first initial power level and the preset target power level.

It should be noted that there is a preset RPI table in the display device. In the table, the RPI gear number and the corresponding RSSI value range are set, and the transmit power difference between adjacent gears is preset. According to the target Bluetooth remote control The Bluetooth signal strength RSSI value and the preset power information report table can determine the first initial power level of the target Bluetooth remote control. For example, refer to the following table 1-1. The specific range value of RSSI in table 1-1 is just an example , does not constitute a restriction on the RPI table. In practice, other range values can be set according to the signal conditions on the production line.

Referring to the following table 1-1, according to the received Bluetooth signal strength of the target Bluetooth remote control, if the received RSSI value of the target Bluetooth remote control is between -66~-62dBm, the corresponding RPI gear number is 5, That is, the first initial power level is 5, and 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 within the lowest receiving range of Bluetooth adaptation, for example, the lowest receiving range is -87 ~-82dBm, then the corresponding gear is 1, that is, the preset target power gear is 1, then the first power gear difference of the target Bluetooth remote controller is calculated as 5-1=4.

Table 1-1 RPI power information report form

RPI number 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 the first response message fed back by the target Bluetooth remote controller based on the connection request, the first response message carrying the second power level difference of the display device;

It is understandable that the target Bluetooth remote controller also has a preset RPI table, and presets the transmission power difference between adjacent gears, the RPI table in the target Bluetooth remote controller and the transmission power difference between adjacent gears The value is the same as the RPI meter in the display device and the transmit power difference between adjacent gears.

After the target Bluetooth remote control receives the connection request sent by the display device, it will also determine the second power level difference of the display device according to the Bluetooth signal strength RSSI value of the display device, and the target Bluetooth remote control calculates the second power level The method of the difference value is the same as the method of calculating the difference value of the first power level of the display device, that is, firstly, the second initial power of the display device is determined according to the received Bluetooth signal strength RSSI value of the display device and the preset RPI table gear, according to the second initial power gear and the preset target power gear to determine the second power gear difference of the display device, and at the same time, the target Bluetooth remote controller will determine according to the first power gear difference in the connection request The target transmission power value, for example, assuming that the transmission power difference between adjacent gears is 1dBm, and the first power gear difference is 4, then it is determined that the adjusted power of the target Bluetooth remote control is 4*1=4dBm, then according to The current transmission power value, if the current transmission power value is 8dBm, then it can be determined that the target transmission power value of the target Bluetooth remote controller is 8-4=4dBm, and the target Bluetooth remote controller then sends a message to the display device with the reduced target transmission power value of 4dBm The first response message carries the difference value of the second power level, and at the same time, in the subsequent pairing process, the response message is sent to the display device with the reduced target transmit power value.

In the early stage of pairing, the target Bluetooth remote controller sends a connection request with reduced power to the target Bluetooth remote controller, and then in the subsequent pairing process, the target Bluetooth remote controller sends a response message to the display device with the reduced target transmission power value, thereby reducing the need for pairing. The interference of pairing between other display devices and Bluetooth remote controls further improves the accuracy of pairing between display devices and Bluetooth remote controls on the production line.

Step A50, determining the first target transmission power of the display device according to the second power level difference;

Optionally, the step of determining the first target transmit power of the display device according to the second power level difference includes:

Step D1, determining the adjusted power according to the second power gear difference and the transmit power difference between preset adjacent gears;

It can be understood that after the display device receives the first response message sent by the target Bluetooth remote controller, according to the second power level difference in the first response message and the transmission power difference between preset adjacent gears, That is, the adjusted power of the display device can be determined; for example, if the second power level difference is 3, and the transmission power difference between adjacent levels is 1dBm, then the adjusted power is 3*1=3dBm.

Step D2, determining a first target transmit power of the display device according to the current transmit power value and the adjusted power.

It can be understood that the first target transmit power of the display device can be determined according to the current transmit power value and the adjusted power, for example, the current transmit power value is 8dBm, and the adjusted power is 3dBm, then the first target transmit power of the display device can be determined It is 8-3=5dBm.

In the early stage of pairing, the display device reduces the transmission power according to the power level difference sent by the target Bluetooth remote control, and in the subsequent pairing process, the display device sends a request and Respond to the message, thereby reducing the interference on the pairing of other display devices and the Bluetooth remote controller, and further improving the accuracy of pairing between the display device and the Bluetooth remote controller on the production line.

Step A60, sending a pairing request to the target Bluetooth remote controller according to the first target transmission power, so as to complete the Bluetooth pairing between the display device and the target Bluetooth remote controller.

It should be noted that after the first target transmit power is determined, the display device sends a pairing request to the target Bluetooth remote controller with the first target transmit power value, and in the subsequent pairing process, the display device uses the reduced first target transmit power value. A target transmission power value sends request and response messages to the target Bluetooth remote controller to complete the subsequent pairing, which can reduce the interference on the pairing of other display devices and Bluetooth remote controllers, and further improve the pairing of display devices and Bluetooth remote controllers on the production line. accuracy.

After the display device is powered on, the present invention starts the Bluetooth scanning function, and detects the Bluetooth signal strength of the scanned Bluetooth remote controllers; and determines the target Bluetooth among multiple Bluetooth remote controllers according to the detected Bluetooth signal strengths of multiple Bluetooth remote controllers. Remote control; send a connection request with the first power level difference to the target Bluetooth remote control, and receive the first response message fed back by the target Bluetooth remote control based on the connection request, the first response message carries the second power level difference, the display device determines the first target transmit power according to the difference of the second power level, and sends a pairing request to the target Bluetooth remote controller with the first target transmit power, and completes the subsequent pairing process. By setting the signal strength detection mechanism and judgment mechanism on the display device side, the display device can automatically select the target Bluetooth remote control to be paired with it, and send a pairing request to the target Bluetooth remote control with the reduced first target transmission power after the connection is established , to complete the following pairing process, which reduces the interference on the pairing of other display devices and Bluetooth remote controls during the pairing process, so that multiple display devices can be paired with multiple Bluetooth remote controls at the same time on the production line without mismatching problems, high adaptation efficiency, and improved production efficiency.

Optionally, in step A20, the step of determining the target Bluetooth remote controller among the multiple Bluetooth remote controllers according to the detected Bluetooth signal strengths of the multiple Bluetooth remote controllers includes:

Step A21, according to the detected Bluetooth signal strengths of multiple Bluetooth remote controllers, use the Bluetooth remote controller with the strongest Bluetooth signal strength as an alternative Bluetooth remote controller;

It is understandable that since multiple display devices and multiple Bluetooth remote controls are adapted at the same time, there may be multiple Bluetooth remote controls scanned by the display device, and the display device can receive beacon frames sent by the Bluetooth remote control. Analyze and obtain the MAC address and RSSI (Received Signal Strength Indication) value of the Bluetooth remote controller. Different Bluetooth remote controllers have different RSSI values due to the different distances from the display device. According to the obtained RSSI values of multiple Bluetooth remote controllers can determine the Bluetooth remote controller with the strongest Bluetooth signal strength, and use it as a candidate Bluetooth remote controller.

Step A22, comparing the Bluetooth signal strength of the candidate Bluetooth remote controller with a preset threshold;

Step A23, if the Bluetooth signal strength of the candidate Bluetooth remote controller is greater than or equal to a preset threshold, use the candidate Bluetooth remote controller as a target Bluetooth remote controller.

It should be noted that after determining the candidate Bluetooth remote controller with the strongest Bluetooth signal strength, the RSSI value of the candidate Bluetooth remote controller is compared with the preset threshold to determine whether the Bluetooth remote controller with the strongest Bluetooth signal is faulty. The preset threshold is -30dbm~-40dbm. If the Bluetooth signal strength of the alternative Bluetooth remote control is greater than or equal to the preset threshold, it means that there is no fault with the alternative Bluetooth remote control, and the alternative Bluetooth remote control will be used as the target to be paired For the Bluetooth remote controller, if the Bluetooth signal strength of the alternative Bluetooth remote controller is less than the preset threshold, it means that there is a fault in the alternative Bluetooth remote controller, and the Bluetooth scan is continued.

By setting the signal strength detection mechanism and judgment mechanism on the display device side, it is not necessary for production workers to select the target Bluetooth remote control to be paired, and the display device can automatically select the one with the strongest signal strength according to the Bluetooth signal strength of multiple Bluetooth remote controls. As an alternative Bluetooth remote control, the Bluetooth remote control simplifies the operation of the production operator, and can also avoid the situation of pairing multiple display devices with multiple Bluetooth remote controls at the same time. Set a preset threshold and compare the signal strength of the alternative Bluetooth remote controller with the preset threshold to eliminate the faulty Bluetooth remote controller and avoid pairing with the faulty Bluetooth remote controller.

Further, if the Bluetooth signal strength of the candidate Bluetooth remote control is greater than or equal to a preset threshold, before the step of using the candidate Bluetooth remote control as the target Bluetooth remote control, the step further includes:

Step E1, if the Bluetooth signal strength of the candidate Bluetooth remote controller is greater than or equal to a preset threshold, calculate the pairing distance between the candidate Bluetooth remote controller and the display device according to the signal strength of the candidate Bluetooth remote controller;

Step E2, judging whether the pairing distance is less than a preset distance;

Step E3, if the pairing distance is less than the preset distance, then use the candidate Bluetooth remote controller as the target Bluetooth remote controller.

It should be noted that when the Bluetooth remote controller closest to the display device is faulty, the Bluetooth remote controller with the strongest Bluetooth signal strength detected by the display device may not be the one closest to the display device, but may be the one next to it. That bluetooth remote.

After the display device determines the candidate Bluetooth remote controller with the strongest Bluetooth signal, the pairing distance between the candidate Bluetooth remote controller and the display device can be calculated according to the Bluetooth signal strength of the candidate Bluetooth remote controller, and the distance between the paired distance and the preset Bluetooth remote controller can be judged. The size of the set distance, the preset distance can be set according to the distance between the display device and the target Bluetooth remote control during the adaptation on the production line; when the calculated pairing distance between the alternative Bluetooth remote control and the display device is less than the preset distance When , it means that the detected candidate Bluetooth remote control is the Bluetooth remote control closest to the display device, and the candidate Bluetooth remote control is used as the target Bluetooth remote control; when the calculated pairing distance between the candidate Bluetooth remote control and the display device is When the distance is greater than or equal to the preset distance, it means that the Bluetooth remote controller scanned by the display device is not the Bluetooth remote controller closest to the display device, but the Bluetooth remote controller next to the display device, and it cannot be paired with it, then proceed to Bluetooth scanning.

By calculating the pairing distance between the optional Bluetooth remote controller and the display device, and judging whether the pairing distance is smaller than the preset distance, if the distance is smaller than the preset distance, then using the alternate Bluetooth remote controller as the target Bluetooth remote controller, and pairing, so that when the Bluetooth remote controller closest to the display device is faulty, the display device is prevented from being paired with the Bluetooth remote controller next to it, and the accuracy of adaptation is improved.

Furthermore, an embodiment of the present invention also proposes a display device, the display device includes: a memory, a processor, and a computer program stored in the memory and operable on the processor, the computer program being executed by the The steps of each embodiment of the above-mentioned Bluetooth batch pairing method are realized when the processor executes.
