Description

A structure and application of an infrared reflective sensor type toy aircraft for height and air pressure detection

technical field

The invention relates to a toy aircraft, in particular to a structure and application of an infrared reflective induction type toy aircraft for detecting altitude and air pressure.

Background technique

At present, the general remote control toy aircraft can usually only realize the forward and backward, up and down movement of the aircraft through the remote control, and cannot achieve better interactivity through the remote control.

In the previous public document with the notification number CN202128908U, the applicant discloses an infrared sensing toy helicopter aircraft. The toy aircraft uses the infrared emission and reception at the bottom to realize the lift by self-judgment and detection. The aircraft is relatively interactive. Well, it is very popular among children. However, this product can only achieve up and down lifts in turn, and cannot achieve front and rear drive like ordinary remote control aircraft.

The altitude detection of the above-mentioned aircraft is carried out through the infrared detection mechanism, that is, the current altitude of the aircraft is detected through the infrared emission receiving detection mechanism at the bottom of the helicopter main body, and the detection mechanism feeds back the obstacle information to the built-in helicopter main body. The main control circuit inside controls the action of the motion mechanism, so that the aircraft and the obstacles below or the ground are maintained within a certain flight height range. However, the altitude value detected by the infrared detection mechanism is relative to the ground or obstacles. When the aircraft encounters obstacles such as tables and chairs, it will rise accordingly. At this time, the aircraft will become difficult to control, and Using infrared to detect the altitude will also cause errors due to the color of the ground and obstacles, and it is easy to cause interference due to sunlight and other factors outdoors, resulting in poor altitude stability of the aircraft and unstable flight process.

Detailed ways

With reference to Fig. 1 - Fig. 7 , a kind of altitude air pressure detection infrared reflection induction type toy aircraft of the present invention, comprises aircraft main body 1, and the bottom of described aircraft main body 1 is installed with the infrared ray emission receiving detection mechanism 3 that is used to detect the obstacle around the aircraft, The infrared emitting and receiving detection mechanism 3 includes a plurality of infrared emitting ends 31 and more than one corresponding infrared receiving ends 32, the infrared emitting ends 31 point to a plurality of different angles obliquely below the aircraft main body 1, and the aircraft main body 1 is provided with air pressure Altitude sensor, the main body of the aircraft 1 is provided with a motion mechanism 4 to drive it up and down, forward and backward. When in use, the barometric altitude sensor knows the altitude of the aircraft according to the air pressure value of the aircraft main body 1, and feeds back the altitude information to the main controller. Circuit, the main control circuit controls the movement mechanism 4 to keep the aircraft within a certain flight height range. When there is an obstacle at the corresponding oblique lower part of the aircraft or at the oblique lower part adjacent to more than one angle, the detection mechanism will feed back the obstacle information to the built-in The main control circuit in the main body 1 of the aircraft controls the movement of the movement mechanism 4 to avoid movement or rotation in the other direction.

Since the bottom of the aircraft main body 1 is provided with a plurality of infrared signal transmitters at different angles corresponding to the slanted lower part of the aircraft main body 1, obstacles in different positions can be detected, and the front and rear, left and right, and oblique upward directions of the aircraft can be realized through the main control circuit of the aircraft. , slanting, ascending and descending movements, with excellent interaction; the barometric altitude sensor knows the altitude of the aircraft according to the air pressure value of the aircraft main body 1. Since the altitude information is only related to the current atmospheric pressure value, the flight altitude will not be affected by the air pressure on the ground. Obstacles of different heights change, so that the aircraft is always maintained within the user-operable height range, and the present invention does not need to detect the height of the ground through infrared rays, so it will not be caused by factors such as the color of the ground and outdoor sunlight during use. interference, so that the altitude stability of the aircraft is good and the flight process is stable.

Although, in order to solve the error and instability caused by the infrared detection height, the ultrasonic module can also be used to detect the flying height of the aircraft, that is, the original height infrared transmitter can be replaced by the ultrasonic module, and the integrated transmitter and receiver can be selected. Ultrasonic module can also be equipped with ultrasonic transmitter and ultrasonic receiver respectively, and the flight height of the aircraft can be measured by the above method, which can effectively reduce the errors caused by light and ground color. However, due to the large volume, heavy weight, complex electronic parts and poor consistency of the ultrasonic module, the limited detection effective height distance (4-5 meters), and the appearance of the product will be affected, so in the present invention, the ultrasonic mode is not used to adjust the flying height. Instead, the built-in barometric altitude sensor is used to detect the air pressure value in the air, which is not only light in weight, simple in circuit, but also can be built in the main body 1 of the aircraft, so the overall appearance of the aircraft is better.

During the operation of the aircraft, the air pressure altitude sensor continuously detects the air pressure value at the current flight altitude. Since the air pressure values at different altitudes are different, the flight altitude of the aircraft can be obtained according to the current air pressure value. When the aircraft rises, the air pressure value drops. , when the main control circuit judges the flight altitude of the aircraft through the air pressure value beyond the preset range, the lifting force of the aircraft is controlled to decrease, and the aircraft goes down; when the aircraft descends, the air pressure value rises, and the main control circuit judges that the aircraft has descended to When the height is preset, the motion mechanism 4 is controlled to make corresponding actions to raise, so that the basic cycle keeps the aircraft within a flying height range that can be controlled by the user.

Control circuit, the movement mechanism 4 is controlled by the main control circuit, so that the aircraft and the obstacles below or the ground are maintained within a certain flight height range, and avoid movement or rotation in another direction away from the obstacles obliquely below the aircraft.

It also includes an infrared gesture sensing mechanism 2, including an infrared gesture signal transmitter 21 and an infrared gesture signal receiver 22, both of which are arranged on the upper side of the tail 12. In addition, the infrared gesture sensing mechanism 2 can also be arranged on the body 11.

During use, the aircraft is in a static state, and the user makes a gesture on the infrared gesture sensing mechanism 2. After the infrared gesture signal receiver 22 receives the gesture reflection signal, the main control circuit controls the clockwise rotation of the wind blade 41 and the counterclockwise rotation of the wind blade 42 to start. , the aircraft takes off, and during the operation of the aircraft, when the aircraft flies above a certain altitude, the barometric altitude sensor detects that the air pressure is lower than a threshold, and the main control circuit confirms that the flying altitude of the aircraft exceeds the preset range, thereby controlling the lifting of the aircraft The air pressure drops, and the aircraft descends; the air pressure altitude sensor detects that the air pressure is higher than a threshold value, and the main control circuit confirms that the aircraft has descended to a preset altitude, thereby controlling the motion mechanism 4 to make corresponding actions and ascend, so that the basic cycle makes the aircraft maintain Within a flight altitude range that can be controlled by the user. When the user makes a gesture on the infrared gesture sensing mechanism 2 again, after being recognized, the main control circuit controls the aircraft to change the flight mode or shut down and land, and the whole operation process does not need to be operated by a remote controller.

The present invention is a control method for an infrared reflective induction type toy aircraft with height and air pressure detection. During the flight of the aircraft, the air pressure altitude sensor measures the air pressure value of the current height of the aircraft main body 1, and the current flying height of the aircraft main body 1 is obtained through the air pressure value, and Feedback the altitude information to the main control circuit to control the action of the motion mechanism 4 so that the aircraft main body 1 remains within the flying height range that can be manipulated by the user. When the infrared signal sent encounters an obstacle, the infrared signal is reflected and received by the infrared receiving end 32, and the motion mechanism 4 of the helicopter will move in another direction. Around the obliquely below the aircraft, the infrared signal sent by the corresponding infrared transmitting end 31 of the infrared transmitting and receiving detecting mechanism 3 of the helicopter is reflected after encountering an obstacle, received by the infrared receiving end 32, and processed by the main control circuit. The main control circuit controls the action of the movement mechanism 4 to avoid movement or rotation in the other direction.

Because the altitude corresponding to the atmospheric pressure value is the altitude, not the relative height from the ground where the user stands, and because the altitude of the ground where the user stands is different in different places, it is not enough to measure the air pressure value when the aircraft is flying. The aircraft is maintained within the flying altitude range controlled by the user. During use, the aircraft is placed on the ground to take off. When the aircraft main body 1 of the present invention takes off, the air pressure altitude sensor measures the current air pressure value to obtain the altitude when the aircraft takes off. During the flight process of the aircraft main body 1, the air pressure altitude sensor measures the current flight altitude. The air pressure value is used to obtain the altitude of the aircraft during flight, and the altitude difference between the altitude during flight and the altitude during take-off is the relative height of the aircraft from the ground when it takes off. At this time, the main control circuit controls the movement mechanism 4 according to the relative flight altitude information. The main body of the aircraft 1 is maintained within the flying height range that can be controlled by the user.

Further, the infrared gesture signal transmitter 21 on the main body of the toy continuously emits gesture sensing signals. When the gesture sensing signal is reflected by the user's gesture, the reflected signal is received by the infrared gesture signal receiver 22, and the infrared gesture sensing mechanism 2 will detect The user's gesture signal is fed back to the main control circuit built in the main body of the toy. The main control circuit controls the main body of the toy to start, switch operating modes or shut down and stop. There is no need to use a remote control for operation, and the experience effect is very good.

Specifically, the gesture sensing signal emitted by the infrared gesture signal transmitter 21 is blocked and reflected by the user's gesture, and the reflected signal is received by the infrared gesture signal receiver 22. At this time, the main control circuit controls the movement mechanism 4 to start, and the toy starts to move. , the gesture sensing signal emitted by the infrared gesture signal transmitter 21 is blocked and reflected by the user's gesture again, and the reflected signal is received by the infrared gesture signal receiver 22. At this time, the main control circuit switches the corresponding operating mode or shuts down according to different gesture signals. . When the user gesture is detected to take off, it is set to the suspension mode. When the aircraft receives a single gesture sensing signal during the flight, the main control circuit controls the aircraft to switch between the suspension mode and the wave mode. When continuous gesture sensing signals are received, the main control circuit controls the aircraft to shut down and land.

In addition to using gestures for manipulation in the present invention, a remote controller can also be provided for auxiliary manipulation.

When the user is in use, the ground on which he stands is not necessarily flat, and the aircraft of the present invention obtains the flight height information by measuring the air atmospheric pressure value, which will not change with the height of the ground. At this time, the aircraft may appear Flying out of the user's operable range, for example, the aircraft takes off on the ground above a step and flies to the relative air below the step. At this time, the user is standing under the step, and the flying height of the aircraft is higher than the user's operable height. If the operation cannot be continued, the altitude of the aircraft can be lowered through the remote control to bring it back to the altitude range that the user can operate. However, since the opening, closing, and control of the present invention are all realized by the user's gesture operation, there is no need to use a remote controller during use, so it will be inconvenient to look for the remote controller when the aircraft is higher than the operator's altitude range. . In order to solve this problem, during the flight of the aircraft of the present invention, when the infrared emitting and receiving detection mechanism 3 does not detect an obstacle for a long time, the main control circuit controls the motion mechanism 4 to act, gradually reducing the flying height. And in the process of gradually lowering the flight altitude, when the infrared emission receiving and detecting mechanism 3 detects that there is an obstacle at the corresponding oblique lower part of the aircraft main body 1 or at the oblique lower part adjacent to more than one angle, the main control circuit controls the aircraft main body through the movement mechanism 4. 1. Ascend to the normal flight altitude just now, or use the current altitude when an obstacle is detected as the new normal flight altitude (the altitude that can be operated by the user).

In the process of gradually lowering the flying altitude without detecting obstacles for a long time by the infrared emitting and receiving detection mechanism 3, when the infrared emitting and receiving detecting mechanism 3 detects that there are obstacles on the corresponding oblique lower sides of all aircrafts, it is judged that the current aircraft main body 1 It is close to the ground. At this time, the main control circuit controls the disconnection of the power supply to let the aircraft main body 1 land on the ground or measure the air pressure value of the current height through the air pressure altitude sensor as a reference reference zero point, and the aircraft main body 1 rises again through the movement mechanism 4 and maintains it at the user's level. Within the range of manipulable height (that is, to readjust the relative height to the ground).

Through the above method, when the aircraft flies out of the user's operating range, the aircraft can be returned to the normal user's operable range without using the remote controller, making it more practical.

Below in conjunction with the three-way induction helicopter and the four-axis induction aircraft of the first to third embodiments of the present invention's altitude air pressure detection infrared reflection induction toy aircraft of the present invention, this method is described in detail. With reference to Figure 8 , the aircraft is in a static state. , turn on the power of the aircraft, if you receive the power-on signal from the remote control, detect the air pressure value at the current altitude as the reference zero point, start the aircraft, and set the flight mode to hover mode, if you do not receive the power-on signal from the remote control, infrared gesture The signal transmitter 21 continuously transmits the gesture sensing signal until it receives a remote control signal or generates a reflected signal due to the user's gesture blocking. After the infrared gesture signal receiver 22 receives the reflected signal, it detects the air pressure value at the current altitude as a reference zero point, and controls The circuit controls the aircraft to start take-off, and set it to the suspension mode. At this time, if the infrared gesture sensing mechanism 2 senses a single gesture sensing signal, then switch the flight mode to the wave mode. If it senses a continuous gesture sensing signal or receives The remote control shutdown signal, the control circuit controls the aircraft to shut down and land, the barometric altitude sensor detects and obtains the current flight altitude and the relative flight altitude relative to the reference zero point, and then polls and detects obstacles in front, left, rear, and right in turn. And according to the detected obstacles, the aircraft will be comprehensively processed. If the current flight mode is the suspension mode, the flight height will float in the suspension height. If the current flight mode is the wave mode, the flight height will be set at the upper, Up and down in the next two altitudes, if a single gesture sensing signal is received during the flight, it will switch back and forth between the suspension mode and the wave mode.

It should be noted that, in all the above-mentioned embodiments, in addition to detecting obstacles in the front, left, rear, and right by means of polling, the infrared emission and reception detection mechanism 3 can also use unique information contained in each infrared emission signal. ID code way to carry out orientation identification detection, that is, all infrared transmitters 31 transmit infrared signals simultaneously or in groups, each group of infrared signals contains a specific ID code, and the main control circuit distinguishes the corresponding infrared transmitter by detecting a specific ID code 31.

Referring to Figure 9 to Figure 13 , the three-way induction helicopter of the present invention can be shown in the figure , as shown in Figure 9 , when the aircraft is stationary, it detects the upper user's gesture signal, the aircraft takes off, and the aircraft is maintained in the suspension mode or wave mode by detecting the altitude. When the aircraft is flying, if it detects the upper user gesture signal, it will control the aircraft to switch the flight mode or shut down and land. When as shown in Figure 10 , the toy aircraft detects obstacles at the front and bottom, then the tail wind vane 43 of the motion mechanism 4 blows upwards to make its tail downward, and the toy aircraft moves backward; as shown in Figure 11, when the right side of the toy aircraft When an obstacle is detected obliquely below, the toy aircraft will turn to the left; as shown in Figure 1 2, when an obstacle is detected on the left rear side of the toy aircraft, the toy aircraft will turn to its right front side, making the toy aircraft have better interaction sex. For example, when the size of the toy aircraft is small, the player's hand can be used as an obstacle to drive away the toy aircraft, which can make the toy aircraft fly left and right, front and back, obliquely upward, obliquely downward, ascending and descending in front of the player, and the interaction is excellent. When the infrared emission and reception detection mechanism 3 does not detect the user operation for a long time, the main control circuit controls the movement mechanism 4 to gradually reduce the flying height, as shown in Figure 1 3, when the infrared emission and reception detection mechanism 3 detects the corresponding When there are obstacles obliquely below, it is judged that the main body 1 of the aircraft is close to the ground. At this time, the main control circuit controls to disconnect the power supply to let the main body 1 of the aircraft land on the ground, or measure the air pressure value at the current altitude through the air pressure altitude sensor as the reference zero point, and pass The movement mechanism 4 makes the main body of the aircraft 1 rise again and maintain it within the height range that can be manipulated by the user (that is, to readjust the relative height to the ground).

The four-axis induction aircraft of the present invention detects the gesture signal of the upper user when the aircraft is stationary, and the aircraft takes off, and maintains the aircraft in the suspension mode, flip mode or wave mode by detecting the height. When the aircraft is flying, the gesture signal of the upper user is detected, and the aircraft is controlled to switch Airplane mode or shutdown to land. When the obstacle is detected at the front and bottom of the toy aircraft, the movement mechanism 4 is used to move backwards. Similarly, the toy aircraft can be left, right, front and rear, obliquely upward, obliquely downward, upward, and downward in front of the player according to the detected obstacles in different directions. flying. If obstacles are detected at the front and top of the aircraft, the movement mechanism 4 moves backwards, and the toy aircraft can also fly left, right, front and rear, obliquely upward, obliquely downward, upward, and downward in front of the player according to the detected obstacles in different directions. Very interactive. When the infrared emission and reception detection mechanism 3 does not detect user operation for a long time, the main control circuit controls the motion mechanism 4 to act and gradually lower the flying height. When it is judged that the current aircraft body 1 is close to the ground, the main control circuit controls to disconnect the power supply to allow the aircraft body 1 to land on the ground, or measure the air pressure value of the current altitude through the air pressure altitude sensor as a reference reference zero point, and make the aircraft body 1 through the movement mechanism 4. The main body 1 rises again and maintains within the height range that can be manipulated by the user (that is, readjusts the relative height to the ground).

The above descriptions are only preferred embodiments of the present invention, and the present invention is not limited to the above-mentioned embodiments, as long as they achieve the technical effects of the present invention by the same means, they should all belong to the protection scope of the present invention.
