Description

Technical Field

[0001] The invention belongs to the technical field of dome control, and in particular relates to a remote control device for a ship-borne follow-up dome. Background Art

[0002] At present, the ship-borne follow-up dome is usually installed at the highest point of the ship. The optical measurement equipment and the ship-borne follow-up dome controller are placed inside the ship-borne follow-up dome respectively, and the optical measurement equipment is located at the center of the ship-borne follow-up dome. The optical measurement equipment control room is located in the middle layer of the ship. The distance between the optical measurement equipment control room and the ship-borne follow-up dome controller is about 2 floors. Before using the optical measurement equipment, the operator needs to go inside the ship-borne follow-up dome, use the ship-borne follow-up dome controller to open the dome skylight, and switch the control command of the ship-borne follow-up dome controller to the follow-up mode to ensure that the follow-up function of the ship-borne follow-up dome is normal, and then the operator returns to the optical measurement equipment control room to operate the optical measurement equipment.

[0003] This operation mode has the following two problems: 1. Since the operator needs to run back and forth between the floor where the optical measurement equipment control room is located and the floor where the ship-borne follow-up dome is located, it will waste the operator's physical strength and time, and at the same time reduce the test efficiency of the optical measurement equipment.

[0004] 2. Since the operator needs to enter the interior of the ship-borne follow-up dome to operate the ship-borne follow-up dome, the ship-borne follow-up dome requires a larger internal space, resulting in a larger space occupied by the ship-borne follow-up dome. Summary of the invention

[0005] In view of this, the present invention aims to provide a remote control device for a ship-borne follow-up dome to solve the technical problem that the ship-borne follow-up dome cannot be remotely controlled and occupies a large space.

[0006] To achieve the above object, the technical solution created by the present invention is implemented as follows: A remote control device for a ship-borne servo dome comprises a proximal controller and a distal controller, wherein the proximal controller is installed on the same layer of the ship-borne servo dome and on the outside of the ship-borne servo dome, and the distal controller is installed in a light measuring device control room, the proximal controller communicates with the distal controller via a network communication mode, and the proximal controller and the distal controller communicate with a light measuring device encoder and a dome encoder respectively via a serial port communication mode.

[0007] Furthermore, both the proximal controller and the distal controller include an external communication interface module, a network communication module, a D / A conversion module, an FPGA controller and a single-chip microcomputer; wherein the FPGA controller is used to collect azimuth data of the optical measuring device encoder and the dome encoder through the external communication interface module, and send the data to the single-chip microcomputer; the network communication module is used to connect the proximal controller and the distal controller to realize network communication between the two; the single-chip microcomputer is used to calculate the current angular velocity and position of the optical measuring device and the current angular velocity and position of the ship-borne follow-up dome according to the azimuth data of the optical measuring device encoder and the dome encoder, and generate a control signal to send to the D / A conversion module; the D / A conversion module is connected to the dome motor driver, and is used to convert the control signal into an analog signal and send it to the dome motor driver to control the dome motor.

[0008] Furthermore, the remote controller also includes a display module for displaying in real time the current angular velocity and position of the optical measuring device and the current angular velocity and position of the ship-borne follow-up dome.

[0009] Furthermore, the display module is an RGB screen, and the user interface is developed using the LVGL graphics library.

[0010] Furthermore, the external communication interface module includes an IO module and / or a serial port communication module.

[0011] Furthermore, the external interface of the IO module and / or the serial communication module is a J30J-31 core connector.

[0012] Furthermore, the interface type of the J30J-31 core connector is an RS-422 interface.

[0013] Furthermore, the interface of the network communication module is a 100M / 1000M RJ-45 connector.

[0014] Furthermore, the D / A conversion module adopts a 12-bit D / A converter.

[0015] Furthermore, the single chip microcomputer adopts GD32F470 chip.

[0016] Compared with the prior art, the invention can achieve the following beneficial effects: 1. The proximal controller is installed on the outside of the ship-borne servo dome. The operator does not need to enter the inside of the ship-borne servo dome to complete the operation of the ship-borne servo dome. Therefore, the size of the ship-borne servo dome can be reduced, thereby reducing the occupied space of the ship-borne servo dome.

[0017] 2. The proximal controller is installed on the same floor of the ship-borne servo dome, and the remote controller is installed in the control room of the optical measurement equipment. The operator can use the remote controller or the proximal controller to operate the ship-borne servo dome. The operator does not need to run back and forth, which saves the operator's physical strength and time, and improves the test efficiency of the optical measurement equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0024] The following will refer to Figure 1-Figure 4 The invention is described in detail with reference to the embodiments.

[0025] like Figure 1 As shown, the present invention provides a remote control device for a ship-borne follow-up dome, including a proximal controller 1 and a remote controller 2. The proximal controller 1 is installed on the same floor of the ship-borne follow-up dome 3 and is installed on the outside of the ship-borne follow-up dome 3. The remote controller 2 is installed in an optical measurement equipment control room 4. The proximal controller 1 communicates with the remote controller 2 through a network communication method. The proximal controller 1 and the remote controller 2 communicate with the optical measurement equipment encoder 5 and the dome encoder 6 through a serial port communication method, respectively.

[0026] Since the proximal controller 1 is installed outside the shipborne servo dome 3, the operator can operate the proximal controller 1 without entering the shipborne servo dome 3 to control the shipborne servo dome 3. In this way, the internal space of the shipborne servo dome 3 can be reduced, thereby reducing the overall size of the shipborne servo dome 3 and further reducing the space occupied by the shipborne servo dome 3.

[0027] Since the floor where the ship-borne servo dome 3 is located and the floor where the optical measuring equipment control room 4 is located are respectively equipped with controllers for controlling the ship-borne servo dome 3, the operator can also control the ship-borne servo dome 3 in the optical measuring equipment control room 4, so the operator does not need to run back and forth, saving the operator's physical strength and time, and improving the test efficiency of the optical measuring equipment 8. The optical measuring equipment 8 in the present invention includes but is not limited to the theodolite.

[0028] The functional modules inside the local controller 1 and the remote controller 2 are substantially the same, and the remote controller 2 is taken as an example for description.

[0029] like Figure 2 As shown, the remote controller 2 includes an external communication interface module 21 , a network communication module 22 , a D / A conversion module 23 , an FPGA controller 24 , a single-chip microcomputer 25 and a display module 26 .

[0030] The FPGA controller 2 adopts a domestically produced chip, which is used to collect the azimuth data of the optical measurement equipment encoder 5 and the dome encoder 6 through the external communication interface module 21 and send it to the single-chip computer 25; the external communication interface module 21 includes but is not limited to an IO module and a serial communication module, and the external interface of the IO module and the serial communication module is a J30J-31 core connector, and the interface type of the J30J-31 core connector is an RS-422 interface, which is used to receive 2-way serial communication data and 1-way sampling in addition to the synchronization signal signal.

[0031] The network communication module 22 uses a 100M / 1000M network communication chip to connect the proximal controller 1 and the remote controller 2 to achieve network communication between the two. The interface of the 100M / 1000M network communication chip is a 100M / 1000M RJ-45 connector.

[0032] The single-chip microcomputer 25 adopts the domestically produced GD32F470 chip. The GD32F470 chip is a mainstream 32-bit microcontroller of the GD32 MCU family of GigaDevice Innovations, with a main frequency of 240MHz, and has the advantages of fast code processing speed and timely response; the single-chip microcomputer 25 is used to calculate the current angular velocity and position of the optical measuring device 8 and the current angular velocity and position of the ship-borne follow-up dome 3 according to the azimuth data of the optical measuring device encoder 5 and the dome encoder 6 and the communication frequency, and generate a control signal to send to the D / A conversion module 23; the D / A conversion module 23 is connected to the dome motor driver 7, and is used to convert the control signal into an analog signal and send it to the dome motor driver 7, and control the dome motor, so that the ship-borne follow-up dome 3 and the optical measuring device 8 are always kept at a fixed angle, realizing the follow-up function of the ship-borne follow-up dome 3.

[0033] The specific calculation method for calculating the current angular velocity and position of the optical measuring device 8 and the current angular velocity and position of the ship-borne follow-up dome 3 based on the azimuth data of the optical measuring device encoder 5 and the dome encoder 6 and the communication frequency belongs to the prior art, so it will not be repeated in the present invention.

[0034] The dome encoder 6 is a 16-bit encoder connected to the dome axis. When the ship-borne follow-up dome 3 rotates one circle, the dome encoder 6 rotates 360°. The dome encoder 6 can be electronically cleared. The communication interface is an RS-422 interface, which is used to receive synchronization signals other than sampling and send azimuth information.

[0035] The dome motor uses a three-phase asynchronous motor, and the dome motor driver 7 uses a frequency converter. One ship-borne follow-up dome 3 is equipped with two dome motors and one dome motor driver 7. The dome motor driver 7 can use analog voltage input, with a maximum working voltage of 5V and a minimum working voltage of 0.01V.

[0036] The display module 26 uses a 5-inch RGB screen, and the user interface is developed using the LVGL graphics library. Figure 3 and Figure 4 As shown, the theodolite is used as the optical measuring device 8, Figure 3 The user interface shown is used to display the current shipboard tracking dome ( Figure 3 and Figure 4 The real-time position and angular velocity of the dome (referred to as the dome in this article) and the theodolite. Figure 4 The user interface shown is used to set the dome working state: follow-up, rotation, zero position and working speed during rotation.

[0037] The user interface of the display screen is developed based on the LVGL graphics library. The operator can view the working status inside the dome through the information displayed on the interface, and can also use the communication control interface to change the internal parameters of the microcontroller and other information.

[0038] The local controller 1 has the same functional modules as the remote controller 2 except that it does not have a display module.

[0039] The remote controller 2 and the near-end controller 1 exchange information in a network communication mode. The operator can switch the controller at will to control the ship-borne follow-up dome 3. When a controller sends a control instruction, the single-chip microcomputer inside the controller responds immediately and processes it.

[0040] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the disclosure of the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in the present invention can be achieved, and this document does not limit this.

[0041] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
