Examples
Referring to fig. 1-4, the present invention provides a technical solution: an intelligent locking device of a power system control cabinet comprises a control cabinet body 10, wherein a cabinet door 20 is hinged to one side wall of the front face of the control cabinet body 10 through a pin shaft, the other end of the cabinet door 20 is connected with the control cabinet body 10 through an intelligent locking assembly 30, and a main switch button 40 connected with the intelligent locking assembly 30 is installed on the cabinet door 20;
the intelligent locking assembly 30 comprises a voice recognition module 2, a DSP control module 310, a reset circuit 320, a voice signal acquisition module 330, a microphone 340, a voice storage module 350, a relay unlocking module 360 and an electronic lock 370;

In fig. 5, T is a power transformer; k is a small relay; s is an unlocking button; RL is the working coil of the electronic lock. The working principle is as follows: after the AC mains supply is connected, the capacitors C1 and C2 are charged fully quickly. When S is pressed, C2 discharges through a relay K, a K normally open contact is closed, C1 discharges to RL, and the electronic lock is opened. If S is not released when pressed, the voltage at the two ends of the C2 is lower than the release voltage of K due to the voltage reduction of the resistor R, the normally open contact of K is quickly disconnected, and RL is powered off, so that the function of automatically limiting the power supply time is achieved. Only when the hands are released, the C1 and the C2 are fully charged, the lock can be unlocked again; the main elements are selected and arranged: the power of a power transformer T is 8-12W; the capacity of the C1 cannot be less than 3300 muF to ensure that the unlocking current is large enough; the rectifier diode VD is 2A100V, and two 1N4001 can also be used in parallel; the contacts of relay K are loaded by 15A. The values of R2 and C2 are flexibly selected according to actual conditions: when the R2 value is small and the C2 capacity is large, the K pull-in time is long, but when the R2 value is too small, the K can not be released. Because the working current of the circuit is large, except the unlocking button S, other parts are close to the electronic lock, and the sectional area of the main circuit lead of the power supply is not less than 0.75mm, so that the working voltage drop of the circuit is reduced.
In fig. 6, when VCC is powered on, C is charged, and a voltage appears across a 10K resistor, so that the single chip microcomputer is reset; after a few milliseconds, C is full, the current on the 10K resistor is reduced to 0, and the voltage is also 0, so that the singlechip enters a working state. During operation, S and C are pressed to discharge. S is released, C is charged again, voltage appears on a 10K resistor, the single chip microcomputer is reset, and after a few milliseconds, the single chip microcomputer enters a working state.
In this embodiment, specifically: a power interface 110 and a heat dissipation opening 120 are installed on a short side wall of the control cabinet body 10, and the power interface 110 is connected with the intelligent locking assembly 30 and the main switch button 40 respectively.
