[0210] In the sixth step, place the binary matrix code 1010010110011001110000000000000000101011110001011110010111110101 into the 8×8 matrix in sequence from left to right and top to bottom; after placing it in the 8×8 matrix, as Figure 3 shown.

[0211] In the seventh step, count Figure 3 the total number E of binary 1s in Figure 3 is 29. Since E = 29 < F = 53, then connect 2 - 1 = 1 Figure 3 8×8 matrix in Figure 4 to form an 8×l6 matrix, as shown.Step 8: Put the binary grid code 11100011001010101010011000010111110000101101001001011 into the matrix with binary 1 in order from left to right and from top to bottom (the binary grid code is placed after or before the binary matrix code, and here the binary grid code is placed after the binary matrix code); Figure 5 Here, find the last two characters in the order from left to right and from top to bottom, and delete all the characters after them. Figure 6 As shown; if the element in the i-th row and j-th column of the matrix is ​​a two-character digit, the binary matrix code should be deleted. Figure 7 shown.

[0213] The ninth step is to extract binary 1 and binary 0 in order from left to right and from top to bottom, and get the first string 10100100000010010000000000000000010001010000100100001010010101100000000100000000000000000101010000001001000011; extract the first character The character string 101001000000100100000000000000000001000101000010010000101000010010101100000000100000000000000000010101010000001001000011 is converted into the second character string 2pVzlUinj2buycWhYzHiP; the second character string is in base 62.

[0214] Step 10: Connect the matrix code a599c0002bc5e5f5 with the second string 2pVzlUinj2buycWhYzHiP to form a third string a599c0002bc5e5f52pVzlUinj2buycWhYzHiP, and convert the third string a599c0002bc5e5f52pVzlUinj2buycWhYzHiP into a QR code. This QR code is the power grid QR code, as shown in the following example: Figure 8 As shown; the grid QR code is displayed on the handheld mobile terminal.

[0215] Step 11: The scanner scans the Figure 8 After entering the grid QR code shown, you will get the entry code a599c0002bc5e5f52pVzlUinj2buycWhYzHiP.

[0216] Step 12: Split the entry code a599c0002bc5e5f52pVzlUinj2buycWhYzHiP into the first entry code and the second entry code:

[0217] Thethirdnumberˊ=Mztrixnumberˊ&Secondnumberˊ

[0218] a599c0002bc5e5f52pVzlUinj2buycWhYzHiP = 599c0002bc5e5f5 & 2pVzlUinj2buycWhYzHiP,

[0219] That is, a599c0002bc5e5f5 is the first entry code and 2pVzlUinj2buycWhYzHiP is the second entry code.

[0220] Step 13: Convert the first entry code a599c0002bc5e5f5 into the binary entry code 1010010110011001110000000000000000101011110001011110010111110101; and convert the second entry code 2pVzlUinj2buycWhYzHiP into the binary second entry code 1010010000001001000000000000000000100010100001001000010100000100101001011000000001000000000000000000101010000001001000011.

[0221] Step 14: Count the total number Qˊ = 64 of binary 0s and binary 1s in the binary entry code 1010010110011001110000000000000000101011110001011110010111110101, and thus form an 8×8 matrix, as Figure 2 shown. If Qˊ = 99, then form a 9×9 matrix.

[0222] Step 15: Place the binary entry code 1010010110011001110000000000000000101011110001011110010111110101 into the 8×8 matrix in order from left to right and top to bottom; after placing it into the 8×8 matrix, as Figure 3 shown.

[0223] Step 16: Since Eˊ = 8×8 = 64 < Fˊ = 121, then after the 8×8 matrix in Figure 3 connect 2 - 1 = 1 Figure 3 The 8×8 matrix in forms an 8×16 matrix, such as Figure 4 shown.

[0224] The seventeenth step is to put the binary entry second code 101001000000100100000000000000000001000101000010010000101000010010101100000000100000000000000000101010000001001000011 into the 8×16 matrix in the order from left to right and from top to bottom (the binary entry second code is placed after or before the binary entry code, and here the binary entry second code is placed after the binary entry code); after being put in, Figure 9 Here, find the last two characters in the order from left to right and from top to bottom, and delete all the characters after them. Figure 10 shown.

[0225] In the eighteenth step, the binary entry second code characters corresponding to the character 1 in the binary entry code are extracted from the matrix in order from left to right and from top to bottom to obtain the fourth character string 11100011001010101010011000010111110000101101001001011; the fourth character string 11100011001010101010011000010111110000101101001001011 is converted into a fifth character string AB Cdef123, which is the judgment code, and the judgment code is in 62-hexadecimal.

[0226] In step 19, since the judgment code exists in the scanner, the scanner sends an open trigger command to the camera. After receiving the open trigger command, the camera determines whether the power grid operator is wearing a power grid safety helmet:

[0227] If the power grid operator wears a power grid safety helmet, the camera sends an open trigger command to the unlocking switch. After receiving the open trigger command, the unlocking switch opens; the power grid operator enters the power grid operation station to perform operations;

[0228] If the power grid operator does not wear a power grid safety helmet, the camera will not send an open trigger command to the unlocking switch, and the camera will send a prompt message to the warning device, which is to wear a power grid safety helmet to enter the power grid operation station.

[0229] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents. < / powergridnumber> < / powergridnumber> < / powergridnumber>
