Description

Rotary bright lamp positioning system and positioning method

The invention relates to a religious blessing device; in particular, it relates to a rotary bright lamp positioning system and a positioning method thereof.

Bright lamps are lamps used in religion for blessings. Among them, tower-type bright lamps can be found in various temples because they can accommodate many small lamp holders to provide lighting for many believers.

Although the tower-shaped light lamp has a large number of light lamp holders, it also increases the burden on believers in finding the light lamp holders they have ordered. In the early days, the fixed tower-type light lamp had to be a believer walking around the light lamp to find the position of the light lamp holder he had clicked. Although it was later improved into a rotatable mechanism, the believer still turned the bright light by dialing. It was more convenient in the process of searching for the light, but it also hidden the lack of failure due to different believers' turning force and speed. .

Recently, tower-type bright lamps have been further developed to be driven by motors, that is, a driving mechanism including a motor is installed inside the base of the bright lamps. Similar patents such as China's new M392613 "Bright Lamp Improved Structure" patent, new M450320 "Bright Lamp and Its main drive device and auxiliary drive device are patented. It is true that the previously disclosed patented technology uses electric control instead of manual operation to save labor and convenience, but the former patented technology discloses that the one-way bearing makes the rotating device rotate in a fixed direction (such as clockwise), and the latter patented technology discloses that the Palin is linked with the pulley, and all of them have achieved that the light can only rotate in one direction and cannot be reversed. However, for the bright lamp holders on both sides of the reference position of the search lamp, when the light lamp can only rotate in one direction, the bright lamp holder on one side can quickly reach the reference position of the search lamp, and the bright lamp holder on the other side. But it must go through a long distance to reach the reference position of the search lamp. Therefore, the front-revealing technique is not a practical choice.

In addition, some developers have developed a method of controlling the time to stop the rotation of the light. However, in addition to the inconvenience of setting up, it must have accurate time control. When the set rotation time ends, the light will be subject to inertia. The effect of this method stops after the reference position of the search lamp is exceeded. Therefore, this method is still not perfect and needs to be improved.

In view of this, an object of the present invention is to provide a rotary bright lamp positioning system and a positioning method thereof, which have the effects of fast lamp searching and precise positioning.

In order to achieve the above-mentioned object, a rotary bright light positioning system provided by the present invention includes a lighthouse and a base, and the lighthouse is rotatably disposed on the base; a central axis passes between the lighthouse and the base; The motor is disposed in the base; and further includes a transmission mechanism for transmitting the power generated by the motor to the central shaft to rotate the central shaft and drive the lighthouse to rotate. The transmission mechanism includes at least one rotation shaft and the central shaft. Synchronous rotation; an electromagnetic clutch is controlled to release or engage in a controlled manner, wherein the shaft can rotate freely when the electromagnetic clutch is released, and the electromagnetic clutch inhibits the rotation of the shaft when engaged; a controller is used to control the electromagnetic clutch to release or engage Engage; an encoder is used to detect the rotation position of the rotating shaft, and feedback the signal to the controller.

The invention further provides a method for positioning a rotary bright lamp, which includes the steps of: receiving an external instruction to start the motor to drive the central shaft to rotate, the external instruction includes an address signal; detecting the rotation position of the central shaft, and When the rotation position of the central shaft reaches the position indicated by the address signal, a positioning signal is issued; and receiving the positioning signal and stopping the motor, and controlling the electromagnetic clutch to be engaged to stop the central shaft from rotating.

The effect of the present invention is that it can shorten the waiting time for searching for lights and accurately locate the lighthouse.

In order to explain the present invention more clearly, a preferred embodiment is described in detail below with reference to the drawings. Please refer to FIG. 1 and FIG. 2. A rotary bright light positioning system 100 according to a preferred embodiment of the present invention includes a base 10, a lighthouse 12, a central shaft 14 and a motor 16. The lighthouse 12 is cylindrical and rotatably disposed on the base 10. The peripheral surface of the lighthouse 12 is neatly embedded with a plurality of rows and a plurality of bright lamp holders (not shown), and each bright lamp holder is Represents a lighted prayer. The central shaft 14 is inserted between the base 10 and the lighthouse 12, and the motor 16 is installed in the base 10. After the motor 16 is started, the central shaft 14 can be driven to rotate and drive the lighthouse 12 to rotate. The aforementioned base 10, the lighthouse 12, the central shaft 14, and the motor 16 are known technologies, and will not be repeated here.

The bright lamp positioning system 100 of this embodiment further includes a transmission mechanism, an encoder, an electromagnetic clutch, and a controller. The transmission mechanism includes a first pulley group 18 and a second pulley group 20, and includes a first rotating shaft 22 and a second rotating shaft 24. As shown in FIG. 1, a rotating wheel 18a of the first pulley group 18 sets Connected to the central shaft 14, the other rotating wheel 18b is connected to the first rotating shaft 22, and a belt 18c is used as a transmission between the rotating wheels 18a and 18b; a rotating wheel 20a of the second pulley set 20 is also sleeved on the central shaft 14. The other rotating wheel 20b is connected to the second rotating shaft 24. The belt 20c is also used as a transmission between the rotating wheel 20a and the rotating wheel 20b, and the gear ratio between the rotating wheel 20a and the rotating wheel 20b is 1: 1. The aforementioned first rotating shaft 22 and the second rotating shaft 24 are mounted to a fixing frame 26, and in accordance with the aforementioned connection relationship, the central shaft 14, the first rotating shaft 22 and the second rotating shaft 24 can be rotated synchronously and in the same direction.

The motor 16 is mounted on the fixed frame 26, and has an output shaft 16 a connected to the first rotation shaft 22 and linked. The starter motor 16 can drive the first rotating shaft 22 to transmit power to the central shaft 14 and indirectly drive the second rotating shaft 24 to synchronously rotate. By controlling the forward or reverse rotation of the output shaft 16a, the steering of the central shaft 14 can be changed.

The encoder 28 in this embodiment is an absolute encoder, which is also mounted on the fixed frame 26 and is disposed corresponding to the second rotating shaft 24. The function of the encoder 28 is to detect the rotation position of the second rotating shaft 24. Since the central shaft 14, the first rotary shaft 22 and the second rotary shaft 24 are synchronized and rotate in the same direction, the measured rotational position of the second rotary shaft 24 is equivalent to the rotary position of the central shaft 14.

The electromagnetic clutch 30 is controlled to be disengaged or engaged. In this embodiment, the electromagnetic clutch 30 is installed at a position corresponding to the first rotating shaft 22. When the electromagnetic clutch 30 is disengaged, the first rotating shaft 22 can be rotated freely; conversely, when the electromagnetic clutch 30 is engaged, the first rotating shaft 22 is inhibited from rotating, and the central shaft 14 is stopped to rotate until the first rotating shaft 22 is driven again When turning, the central axis 14 will rotate again.

The controller 32 includes a communication transmission unit 32a, a single chip 32b, a motor drive control unit 32c, an encoder input unit 32d, and a clutch control unit 32e. Among them, the communication transmission unit 32a is used to receive an external instruction including an address signal, and convert the address signal to a single chip 32b; the single chip 32b has calculation and control functions, and is input with the motor drive control unit 32c and the encoder The unit 32d and the clutch control unit 32e are electrically connected respectively. The single chip 32b starts or stops the operation of the motor 16 through the motor drive control unit 32c according to the received command. As for the encoder input unit 32d, the encoder 28 is detected at any time. The rotation position signal of the second rotating shaft 24 is fed back to the single chip 32b, and a positioning signal is issued when the detected rotation position reaches the position indicated by the aforementioned address signal, and the single chip 32b sends a control command to the clutch according to the positioning signal. The control unit 32e and the clutch control unit 32e generate an engagement operation to stop the rotation of the first rotating shaft 22, and at the same time, the motor drive control unit 32c controls the motor 16 to stop operation.

The above is the description of the components and the structural relationship of the components of the rotary bright light positioning system 100 according to the preferred embodiment of the present invention. Please refer to Figures 2 and 3 below to explain the positioning method based on the above structure that can achieve fast lamp search and precise positioning purposes.

When the light seeker is looking for a specific light lamp holder, since the address of each light lamp holder is built into the controller 32, the light seeker only needs to type at the control end (usually the light search reference position). A specific symbol (such as a group number) connected to the spotted (seeking) light socket can output an external command including an address signal, and the external command is transmitted through wireless transmission or wired transmission and is transmitted to the controller 32. Received by the communication transmission unit 32a, the communication transmission unit 32a converts the address signal and transmits it to the single chip 32b. At this time, the single chip 32b starts the motor 16 through the motor driving control unit 32c. Since the single chip 32b has calculation and control functions, the performance in the calculation function is to calculate the shortest turning distance of the point (seeking) light lamp holder to the reference position of the finding lamp; in terms of control functions, it is through the clutch control unit 32e. The electromagnetic clutch 30 is disengaged, and the output shaft 16a of the motor 16 is controlled to forward or reverse according to the shortest rotation distance, so as to drive the central shaft 14 to generate synchronous forward or reverse, thereby achieving control of the lighthouse 12 to minimize The turning stroke reached the reference position.

It is worth mentioning that the above-mentioned control end can be a remote network or a near-end device (such as a remote control). When the remote control is operated via the network, the light seeker visually points (finds) through the camera lens 34. Bright lamp holders. When a remote control is used to search for lights at the scene of praying, the light seeker is directly facing the (seeking) bright lamp holders, which is convenient for praying. It can be known from the foregoing description that the lighthouse 12 can be controlled to rotate forwards or backwards so that the point-seeking (light-seeking) lamp holder reaches the light-seeking reference position with the shortest turning stroke, which has the effect of shortening the waiting time.

In addition, during the rotation of the lighthouse 12 with the central axis 14, the encoder 28 continuously detects the rotation position. When the detected rotation position reaches the position indicated by the address signal of the external command, which means that the positioning signal sent by the encoder 28 is the same as the address signal after the conversion operation, the motor 16 will be controlled by the single chip 32b again to stop And the electromagnetic clutch 30 is controlled to be engaged so that the first rotating shaft 22 stops rotating, and the central shaft 14 also stops rotating. In this way, the lighthouse 12 will definitely stay at the reference position of the light-seeking, which effectively improves the lack of the conventional structure being stopped after the reference position of the light-seeking is affected by the rotational inertia.

To sum up, it can be known that the rotary bright lamp positioning system and the positioning method of the present invention have the effects of fast lamp searching and precise positioning. The above descriptions are only the preferred and feasible embodiments of the present invention, and any equivalent changes made by applying the description of the present invention and the scope of patent application should be included in the patent scope of the present invention.
