Fig. 2 is an appearance effect diagram of the trash can shown in fig. 1.
The trash can and the working condition thereof are briefly described by combining the control schematic block diagram of fig. 3 and the control flow diagram of fig. 4.
The infrared sensor detects whether a person approaches, if no person approaches, the whole machine is in a low-power-consumption operation mode, and only the person approaches the infrared sensor, the whole machine keeps an operation state.
When the infrared sensor detects that someone approaches, the camera is awakened to work, and specifically, the camera is awakened through the processor. The camera acquires image information and transmits the image information to the processor for image analysis processing; the processor is provided with an intelligent chip, a corresponding image processing algorithm is built in the intelligent chip, and whether the face information and the hand information exist in the image information can be judged; if only face information exists and no hand information exists, the user is considered to pass through without the intention of throwing waste products, processing is not carried out, the system continues to keep the detection state until the user leaves the sensing range, and the system returns to the low-power-consumption operation mode; if the hand information is recognized, the intelligent chip sends a control signal to the electromagnetic driver to the electromagnetic coil if the user has the intention of throwing the waste, so that the electromagnetic driver outputs a driving current from small to large to the electromagnetic coil to generate linearly increased electromagnetic force, wherein the S pole faces downwards, and the N pole faces upwards; according to the principle that like magnetic poles repel each other, an upward thrust from small to large is generated on a large permanent magnet at the outer edge of the barrel cover, namely a first magnet, so that the barrel cover is pushed to ascend and suspend at a proper speed until the barrel cover is in a proper position; at the moment, the barrel cover is opened, and a user can throw waste by himself.
When the system is in a magnetic suspension opening state of the barrel cover, namely a floating state, the system continuously works at the moment, whether the current action gesture of a user is garbage throwing is identified, and if the current action gesture of the user is not finished, the barrel cover continues to keep the magnetic suspension state; whether the current action gesture of the user is in the state of finishing the waste throwing can be recognized as whether the image information sent by the camera still has face information and hand information, and if at least one of the face information and the hand information does not exist, the current action gesture of the user is considered to be the state of finishing the waste throwing.
When the barrel cover is kept in stable suspension, namely in a balanced state, the current in the electromagnetic coil is constant, but when the magnetic suspension barrel cover is in an unbalanced position due to the fact that a deviation force is generated by environmental factors such as wind power, manpower and the like, the electromagnetic induction sensor detects that the current magnetic field changes, the processor controls the electromagnetic driver to adjust the output current, the electromagnetic force generated by the electromagnetic coil is slightly strengthened or weakened, and the barrel cover is kept in a specific balanced position.
It should be noted that the second magnet (with the N pole facing downward and the S pole facing upward) located at the center of the barrel cover and the electromagnetic force generated by the electromagnetic coil on the barrel body (with the N pole facing downward and the S pole facing upward) generate a slightly smaller attractive force according to the principle of mutual attraction of different magnetism, so that the barrel cover is maintained to be suspended directly above the magnetic force field without outward deviation; at this time, the barrel cover is in a suspended state which is kept in stable balance under the action of gravity, electromagnetic repulsion and electromagnetic attraction. The repulsive force is strong and the attractive force is weak.
The system recognizes that the current action gesture of the user is a waste throwing completed state, the processor updates the state of the barrel cover to be descending, the processor controls the electromagnetic driver to reduce the current provided for the electromagnetic coil, so that the electromagnetic force generated by the electromagnetic coil is gradually reduced, the repulsive force borne by the magnetic suspension barrel cover is gradually reduced, and the suspension position of the magnetic suspension barrel cover is gradually reduced until the magnetic suspension barrel cover falls back to the upper edge folding position of the barrel body; the current system still keeps the detection recognition state continuously, and if the user has the intention of throwing the waste again, the system enters the next magnetic suspension starting state; if the user finishes throwing the waste and leaves and the system cannot detect the human body, the system is switched to a low-power-consumption operation mode, and the state of the barrel cover is updated to be closed.
The garbage can also control the can cover to open a floating state, keep a balance state and enter a falling state through the touch liquid crystal screen on the inclined panel of the outer wall of the can.
When determining whether a person throws garbage, the identifying hand information may specifically be identifying whether a hand exists, or identifying whether a gesture is a preset gesture motion.
The processor is specifically configured to determine whether the image information sent by the camera includes face information and a preset gesture action, if so, determine that someone throws garbage, and if not, determine that no one throws garbage.
Of course, the processor can also determine whether a person throws the garbage or not only according to whether the preset gesture action exists in the image or not. And when the processor identifies that the preset gesture action exists in the image, determining that people throw the garbage, and otherwise, determining that no people throw the garbage.
The trash can is also opened/closed through gesture recognition by setting a specific gesture.
