Description

Astronomical photography control device

Technical Field

The present invention relates to the field of astronomical photography equipment, and in particular to an astronomical photography control device.

Background Art

Astrophotography is photography that takes constellations, the moon, the sun, etc. as its subjects. Astrophotography is a special photography technique that can record various celestial bodies and phenomena, including the moon, planets, and even distant deep-sky objects. Astrophotography does not necessarily have to be done at night. Some special celestial phenomena, such as solar eclipses, need to be photographed during the day. The equipment required varies depending on the subject, and can be as simple as a single lens reflex camera (SLR) equipped with a standard lens or as complex as a cooled CCD camera connected to a telescope. In addition to observatories, there are a large number of astronomy enthusiasts around the world who are actively involved in this activity. The most important thing is that astronomical photography brings us the opportunity to explore things beyond the earth. Astronomical photography equipment is undoubtedly the most important equipment and method for astronomical photography.

With the development of science and technology, astronomical photography equipment has gradually changed from manual to automatic control. Whether it is the control of the equatorial mount or the focusing camera and other equipment, they are all controlled and coordinated by the controller. However, this also leads to a corresponding problem. When a part of the astronomical photography equipment freezes or stops working, it is necessary to restart the controller to restart the part. However, this method requires the plugging and unplugging of the line during operation, which is not only inconvenient to operate, but also affects the corresponding equipment during the operation, which is undoubtedly troublesome and may even cause the previous photography to fail.

Summary of the invention

The purpose of the present invention is to provide an astronomical photography control device. The advantage of the present invention is that it can intelligently control and restart each part of the astronomical photography control device respectively.

The above-mentioned object of the present invention is achieved through the following technical solutions:

An astronomical photography control device, a telescope including a lens barrel and a camera connected in sequence, the photography control device including a controller detachably connected to the camera, the controller being provided with a power input interface connected to an external power supply, a power supply interface for powering the camera and a camera auxiliary device, and a communication interface for communicating with the camera and the camera auxiliary device, the power input interface being connected to power lines of the power supply interface and the communication interface, the power lines being provided with output virtual switches, and the output virtual switches being connected to a CPU.

By adopting the above technical solution, when using the shooting device, many auxiliary devices are mostly used, such as guide cameras, equatorial mounts, etc. These auxiliary devices and the camera itself need to use power. Since the controller is provided with a power supply interface and a power input interface, only one external power supply needs to be connected during the use of the telescope, and the internal auxiliary devices and cameras can be powered through the power supply interface of the controller. When a device fails, it is only necessary to control the on and off of the virtual switch device through the CPU. Similarly, for the communication between the camera, auxiliary devices and controller, if a communication failure occurs, or the communication connection needs to be disconnected, it is only necessary to control the on and off of the corresponding virtual switch device through the CPU. The above method can avoid wiring and restart operations during the use of the telescope, thereby realizing the intelligent control of the shooting device by the shooting personnel.

As an improvement of the present invention, the power input interface is connected to the power line via an input virtual switch.

By adopting the above technical solution and inputting the setting of the virtual switch, the control of the power access to the controller is realized, that is, the control of the total power supply for the operation of the shooting device is realized.

As an improvement of the present invention, the signal line of the communication interface is connected to the CPU.

By adopting the above technical solution, the signal line is connected to the CPU, so that only one CPU is needed inside the controller to realize the simultaneous control of the power line and the communication line, reducing the complexity of the circuit structure.

As an improvement of the present invention, the CPU is connected to a display screen.

As an improvement of the present invention, the CPU is connected to a wireless transmission module.

By adopting the above technical solution, the wireless transmission module can realize the networking of the telescope, thereby facilitating the simultaneous control of multiple groups of telescopes and the remote control of the telescope.

As an improvement of the present invention, the controller is connected to the camera via a universal coupling.

By adopting the above technical solution, the setting of the universal coupling enables the controller to rotate at any angle, making it convenient for the camera operator to view the display content on the display screen.

As an improvement of the present invention, one end of the universal coupling away from the controller is snap-connected with the housing of the camera.

In summary, the beneficial technical effects of the present invention are:

1. Due to the setting of the output virtual switch and the input virtual switch, the power-on control of the camera and the auxiliary device is realized, which can avoid the wiring and restart operations during the use of the shooting device, thereby realizing the intelligent control of the shooting device by the shooting personnel;

2. Since the external power supply is only connected through the controller, the physical line connection between the camera or auxiliary device and the external power supply is reduced, thereby simplifying the power supply connection.

DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the accompanying drawings.

An astronomical photography control device, as shown in FIG1, is connected to an equatorial mount 4 and a guide camera 53. The telescope includes a lens barrel 1, a connecting tube 2, and a camera 3 connected in sequence, and the photography control device includes a controller 6 connected to the camera 3. The camera 3 obtains an external image through the lens barrel 1, and the connecting tube 2 is used to adjust the size of the image injected into the camera 3. The guide camera 53 is fixed to the front section of the lens barrel 1 through a hoop 51, and the controller 6 is fixed to the outer wall of the camera 3.

Referring to Figure 2 again, the controller 6 is connected to the camera 3 via a universal coupling 61, wherein a clamping member 31 is protruding from the outer wall of the camera 3, and the top of the clamping member 31 is recessed to form a clamping hole, and the end of the universal coupling 61 away from the controller 6 is inserted into the clamping hole to achieve the clamping connection between the controller 6 and the camera 3.

As shown in Figures 2 and 3, the controller 6 is provided with a power interface for connecting an external power supply, a power supply socket for powering the camera 3 and other auxiliary devices such as the guide camera 53 and the equatorial mount 4, and a communication interface for communicating with the camera 3 and other auxiliary devices such as the guide camera 53. The communication interface is preferably a USB interface. The power input interface is provided with an input virtual switch in series, and the power input interface is connected to the power lines of the power supply interface and the communication interface through the input virtual switch. The power lines of the power supply interface and the communication interface are both provided with an output virtual switch, and the input virtual switch is connected between the power input interface and the output virtual switch. Among them, the input virtual switch and the output virtual switch are preferably eight-pin SMD virtual switches.

Furthermore, the input virtual switch and the output virtual switch are respectively connected to a power bus controller 6 through bus communication, and the power bus controller 6 is connected to a CPU, which is preferably an embedded single-chip microcomputer. When a device failure occurs during the shooting process, the CPU can issue an on-off command to directly control the on-off of the input virtual switch or the output virtual switch, thereby eliminating the process of plugging and unplugging the power cord, and can quickly and safely achieve control.

The signal lines in the communication interface are connected to the signal bus controller 6 in a bus manner, and the signal bus controller 6 is connected to the CPU. The camera 3 or the auxiliary device can communicate with each other through multiple communication interfaces.

Furthermore, the CPU is connected to a wireless transmission module and a display screen. The display screen is preferably a touch screen, so that during the shooting process, the display screen can not only be used for viewing, but also can play the role of operation output. The setting of the wireless transmission module enables the CPU to connect to the Internet or directly communicate wirelessly with auxiliary equipment. The model of the wireless transmission module can be selected according to the function of the astronomical shooting control device, and a wireless network card is preferably used here.

As can be seen from the above, when the telescope is used normally, the wireless network card in the controller 6 is connected through the Internet or a computer. If a device problem occurs and power is turned off or restarted in time, a control instruction can be directly input to the CPU through the touch screen, or a control instruction can be input to the CPU through a computer and a network. After the CPU receives the control instruction, it controls the corresponding input virtual switch or output virtual switch to turn on and off, thereby avoiding wiring and restarting operations during the use of the telescope, realizing intelligent control of the shooting device by the shooting personnel, and improving the safety and life of the shooting control device.

The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
