Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0049] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0050] Embodiment 1

[0051] Referring to the attached Figures 1 to 5 As shown, the present invention provides a technical solution: a multi-Bluetooth connection data transmission method, including the following steps:

[0052] S1. Receive requests for pairing from multiple device terminals 100, and configure a unique pairing sequence code for the successfully paired device terminals 100; wherein, if the pairing result is successful, obtain the device information of the device terminals 100.

[0053] S2. According to the device information and the priority sorting rule, obtain a priority list.

[0054] S3. Receive the parameter adjustment data of the detection device and judge the transmission type generated by the device terminal 100 to be transmitted.

[0055] S4. Detect the connection status of the device terminal 100 to be transmitted, and obtain a detection result.

[0056] S5. Based on the detection result and according to the transmission type, transmit the parameter adjustment data to the device terminal 100 to be transmitted.

[0057] Specifically, the device terminal 100 can be a detection device of a smoke meter; the system of the present invention is a wireless router 200, and a Bluetooth module and a positioning module are respectively embedded in the detection device and the wireless router 200. The system of the present invention is embedded in the wireless router 200 to realize Bluetooth interconnection between the detection device and the wireless router 200, and communication interconnection between the wireless router 200 and the server 300.

[0058] Wherein, before the step S1, a unique identifier is created for each device terminal 100.

[0059] Further, the step S1 specifically includes:

[0060] S11. Receive the request plaintexts of multiple device terminals 100, and analyze the request plaintexts.

[0061] S12. Determine whether the unique identifier is carried in the request plaintext based on the device information. If not carried, feedback an unsuccessful pairing result. If carried, feedback a successful pairing result, obtain the device information of the device terminal 100, and simultaneously execute the next step.

[0062] S13. Generate the unique pairing sequence code according to each device terminal 100 and send it to the device terminal 100.

[0063] Specifically, when the device terminal 100 is installed and debugged, or when the device terminal 100 is added later, there will be a situation where multiple device terminals 100 request access. Therefore, in the form of broadcasting, the system of the present invention verifies the unique identifier to achieve pairing, thereby reducing the processing waiting time and further reducing the power consumption of the device, thus realizing device interconnection.

[0064] In a preferred embodiment of the present invention, the device information includes device location information, pairing success time, and unique identifier.

[0065] Further, the step S2 specifically includes:

[0066] S21. Calculate the distance information between the self-position information and the device position information.

[0067] S22. Sort each device information according to the priority sorting rule based on the distance information to obtain the priority list.

[0068] Specifically, in the process of obtaining the distance between the self-position information and the device position information, if the signal strength is used to calculate, when blocked by a wall, the signal strength will inevitably weaken, which will greatly reduce the accuracy of distance calculation. Therefore, in order to obtain accurate distance information, the self-position information and the device position information are obtained by the positioning module using satellite positioning technology.

[0069] In a preferred embodiment of the present invention, the priority sorting rule is: first sort the distance information of each device information from near to far. If the distance information is the same, then the pairing success times of the two device information are sorted according to the time sequence.

[0070] Further, the step S3 specifically includes:

[0071] S31. Receive the parameter adjustment data of the server 300 and determine the device terminal 100 to be transmitted by the detection device.

[0072] S32. Generate the transmission type according to the device terminal 100 to be transmitted.

[0073] Specifically, when the user needs to adjust parameters, the parameter adjustment data is sent to the system of the present invention through the server 300. According to the unique identifier carried by the parameter adjustment data, the device end 100 to be transmitted is determined through the unique identifier, and finally the transmission type can be determined according to the quantitative relationship.

[0074] Further, the step S4 includes:

[0075] S41, sending a tentative response data packet to the device end 100 to be transmitted; wherein, if the device end 100 to be transmitted responds, the step S5 is executed; if the device end 100 to be transmitted does not respond, it is processed according to the transmission rule according to the transmission type, and the next step is executed;

[0076] S42, continuously sending the tentative response data packet to the device end 100 to be transmitted until the device end 100 to be transmitted is awakened.

[0077] Specifically, in the case where the device end 100 to be transmitted does not respond, a tentative response data packet is sent to the device end 100 to be transmitted every other time period. After no response after exceeding the preset number of times, an alarm signal is sent to the server 300 to ensure the normal operation of the device. Among them, the preset number of times is 60 times.

[0078] In a preferred embodiment of the present invention, the transmission type is divided into a first type and a second type. The first type is that there are at least two device ends 100 to be transmitted, and they are transmitted in the order of the priority list. The second type is that there is at least one device end 100 to be transmitted, and it is transmitted according to the unique pairing sequence code.
