Problems solved by technology

[0008] (1) The existing electronic lock has a single unlocking method and poor anti-theft effect;
[0009] (2) The alarm function of the existing electronic lock is not perfect, and it is impossible to check the video when it is abnormally opened
[0011] Multiple identification methods such as fingerprint identification, face recognition, and password identification cannot be reasonably centralized, and the mechanical opening and alarm system are not combined

Embodiment 1

[0129] The main control chip of the present invention scans the input situation of the input module and compares it with the password data stored in advance. The main control chip codes the pre-stored password data, and then diagonalizes the coded signal. Finally, the signal is post-multiplied by the spreading code matrix to obtain time diversity.

[0130] The filtering component of the main control chip digitally filters the encoded pre-stored password data, uses the decoding component to find the local maximum value in the filtered signal waveform, records the x and y coordinates of the maximum value point, and realizes the recognition of the pulse. Calculate the average value of the amplitudes of the previous N pulses as the received signal strength. According to the symbol rate of 2FSK, the total time of each M pulse is counted, so as to distinguish the carrier frequency f 0 and f 1 , to complete the decoding.

[0131] After the decoding is completed, the information p...

Embodiment 2

[0133] Based on embodiment 1, the decoding method of the present invention comprises the following steps:

[0134] Step 1, initialization stage, pulse counter n and signal strength register rss are assigned an initial value of 0.

[0135] Step 2. Identify the pulse from the data sequence, and calculate the amplitude value A of the pulse. The amplitude value A is the maximum value minus the minimum value of all values ​​in the pulse, which is the amplitude of the pulse.

Embodiment 3

[0137] Based on embodiment 2, the present invention also needs to carry out after step 2:

[0138] 1), if a pulse is identified, the pulse counter n is incremented by 1. Add the amplitude A to the signal strength register rss, that is, rss=rss+A;

[0139] 2), judge whether to reach N pulses, if so, go to step 5, otherwise go to step 6.

[0140] 3) Output the average signal strength returned in this operation cycle: avgrss=rss / N.
