sending the picture data to an image recognition server based on an HTTP (hyper text transport protocol);
and receiving the identification result of the image identification server and feeding back the identification result to the mobile terminal for data display.
Specifically, the bluetooth operation body needs to be compiled, called and installed in the USB bluetooth protocol converter, and includes:

and after the image recognition server finishes processing the image information, the image recognition server informs the Bluetooth running body of finishing data processing in a callback mode, and sends the recognition result to the Bluetooth running body in a data packet mode at one time.
S2: and the Bluetooth operation body screens and filters the received signal information by using the set threshold value, and stores the signal information in the integrated service database in a classified manner. The steps to be explained are as follows:
the threshold is set using the SNR strategy as follows
Wherein, SNR: ratio of noise (unnecessary feature information) in received signal information, P: threshold (limit), interference: interfering unwanted signals, power: power, received: received signal information;

Further, the environmental conditions of the substation are complex, and to better illustrate that the method of the present invention can be normally used in a complex environment, the present embodiment uses bluetooth 4.0 to test the communication distance and the actual transmission efficiency with a mobile phone and a notebook computer supporting connection, and the test conditions are as follows:
(1) the Bluetooth 4.0 theoretical transmission rate is 24Mbps (3MB/S), the communication distance is 100M, the frequency is 2.4G, the safety AES128 is adopted, and the power consumption is 0.3 uA-7 mA;
(2) connection condition and transmission efficiency under the distance of 10-100M;
(3) the measuring tape, the mobile phone and the notebook which support Bluetooth 4.0 connection;
(4) an open playground;
(5) ten pictures of 1MB (a total of 10MB of files).
The test results are shown in the following table:
table 1: the bluetooth connection range affects the transmission efficiency data table.
| distance/M | Bluetooth, notebook and mobile phone interconnection | Bluetooth and notebook interconnection |
| 1 | 312kb/s | 301kb/s |
| 10 | 270kb/s | 242kb/s |
| 20 | 140kb/s | 120kb/s |
| 50 | 20kb/s | 15kb/s |
| 100 | Disconnection | Disconnection |
Referring to the data in table 1, it can be seen that, with the increase of the distance, the transmission efficiency under the condition that only the bluetooth and the notebook are interconnected is far lower than that under the condition that the bluetooth, the notebook and the mobile phone are interconnected, and the interconnection of the three is more complex than that under the condition that the bluetooth, the notebook and the mobile phone are interconnected.
Preferably, in order to verify and explain the technical effects adopted in the method of the present invention, the embodiment selects a traditional wireless network construction method and the method of the present invention to perform a comparison test, and compares the test results by means of scientific demonstration to verify the real effects of the method of the present invention; in order to verify that the method of the present invention has higher security and applicability without network limitation compared with the conventional method, in this embodiment, the conventional method of setting up a wireless network and the method of the present invention are respectively used for performing real-time measurement and comparison of data transmission on an image recognition server in a transformer substation, and the test results are shown in the following table:
table 2: and (5) comparing test results with a table.
Referring to table 2, the method of the present invention performs data packet encryption authentication by using AES-128CCM encryption algorithm in bluetooth 4.0, and the added bluetooth operator can only connect the bluetooth mobile device with the specified MAC address, and other devices cannot connect, so as to ensure the security of communication in the substation.
