Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1, an embodiment of the present invention includes a plurality of control circuits 1, mos tubes 2 are disposed on the control circuits 1, the control circuits 1 are connected to a controller 3, and the control circuits 1 are connected to an overvoltage protection module 4. Other electronic peripherals in the monitoring equipment are respectively installed on the control circuit 1, the overload protection module 4 and the controller 3 are both connected with the power supply, after the controller 3 starts working, one mos tube 2 is opened at intervals, so that the camera, the GPU processor, the router, the GPS, the light supplement lamp and other equipment are sequentially powered on in a delayed mode, the load can be increased in a gradient mode, the damage to the power supply caused by an overhigh load is avoided in the moment, the reliability and safety of a product are improved, meanwhile, the overvoltage protection module 4 is not controlled through the controller 3 and only relates to the voltage of the whole circuit, and therefore the monitoring equipment is more stable and safe.
In this embodiment, the overvoltage protection module 4 includes a voltage regulator 401, the voltage regulator 401 is connected to a relay 402, and the relay 402 is connected to a logic judgment circuit 403. After passing through a 12V voltage stabilizer 401, the power is sent to a subsequent logic judgment circuit 403 through a relay 402, and when the voltage exceeds 13.7V, the logic judgment circuit 403 can judge that the voltage is too high to cause danger, so that the mos tube 2 can be controlled to be disconnected, and the safety of electronic components is further protected.
In this embodiment, in order to improve the overall stability and safety, a logic judgment circuit 403 is built by a triode and a zener diode, so that the function failure of the logic judgment circuit 403 is only related to the voltage and does not pass through the logic judgment of the controller 3, thereby being more stable and safe.
In this embodiment, the circuit control board 301 is mounted on the controller 3 so that the use of each component can be known when the power is turned on, and the circuit control board 301 is provided with a buzzer and a speaker. After the controller 3 is electrified to work, the buzzer on the circuit control board 301 sounds, and the buzzer sounds to prove that the main control board works normally. Meanwhile, a voice command is output to the voice module through the serial port of the controller 3, and starting sound is sent out to prove that the serial port communication, the voice module, the loudspeaker and the like work normally. And the controller 3 can control the light filling lamp to turn off after lighting for one second, and the light filling lamp can work normally.
In this embodiment, in order to enable the controller 3 to stably implement the above functions, the controller 3 is selected as an STM32F103RBT6 single chip microcomputer, which has an advanced architecture and further can bring advantages of high performance, low voltage, low power consumption, and the like.
In this embodiment, in order to enable each component to be powered on in sequence in a delayed manner, the controller 3 includes a timer 302, and the time interval of the timer 302 is 0.5 seconds.
