Technical Field

[0001] The invention belongs to the technical field of naval gun fire control systems, and in particular relates to a gun information conversion and simulation device. Background Art

[0002] Ships have the ability to carry artillery. Different ships are generally equipped with artillery of different specifications. Artillery is the control terminal of the ship's gun fire control system. Traditional artillery is connected to the artillery information conversion device on the ship through a cable. The artillery information conversion device is connected to the fire control computer, and the fire control computer is used to send and receive artillery-related information. Specifically, the information sent by the fire control computer includes the artillery's target data (including target azimuth, target elevation, target distance), ammunition type, launch angle, and expected range, and other parameters, while the information received by the fire control computer includes feedback data from the artillery, such as shooting results, ballistic correction parameters, and artillery status information. The accurate transmission and processing of this information is crucial to improving the combat efficiency of the weapon system.

[0003] However, the applicant noticed a problem: naval gun fire control systems generally use naval gun information and gun information conversion devices of different models. Different types of guns need to be equipped with different gun information conversion devices. This situation is no longer suitable for the standardization and modular development trend of naval gun fire control systems, making fault diagnosis and maintenance of naval gun fire control systems inconvenient, resulting in a large waste of resources.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The present invention is a principle block diagram of a gun information conversion and simulation device. DETAILED DESCRIPTION

[0022] In order to better understand the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a gun information conversion and simulation device realizes gun control by connecting to a fire control computer of a ship control center. The gun information conversion and simulation device includes a gun information conversion unit, a control unit, a module working power supply unit, and a gun information self-checking switching unit, wherein:

[0024] The artillery information conversion unit includes an input conversion module and an output conversion module. The output conversion module is used to receive the artillery aiming information calculated by the fire control computer, and convert it into AC information of the synchronous machine or rotary transformer that can actually drive the artillery, and then send it to the artillery. These AC signals will drive the synchronous machine to enable the artillery to accurately aim and shoot according to predetermined parameters. The artillery aiming information includes ammunition type, launch angle, expected range, target azimuth, target elevation, target distance, etc. The input conversion module is used to convert the AC information of the synchronous machine or rotary transformer including the high and low azimuth position information emitted by the artillery into DC information, and send it to the fire control computer.

[0025] The control unit involves an automatic uploading mechanism for the working status of the conversion channel, which is used for automatically uploading the gun information of the output conversion module and transmitting the working data of the conversion channel to the fire control computer, that is, the control unit can transmit the working data of the input conversion module and the output conversion module (the working data includes the data after the input conversion module converts the analog signal of the gun, such as the elevation and azimuth position information, into a digital signal, and the output conversion module converts the digital signal of the fire control computer into an analog signal) to the fire control computer.

[0026] The simulation unit is used to receive commands from the fire control computer and convert the digital artillery information sent by the fire control computer into simulation information with real artillery.

[0027] The artillery information self-check switching unit is used to switch the artillery information during the self-check of the artillery information conversion simulation device (real-time monitoring of circuit status, once an abnormality is found, immediate measures are taken, such as switching to a backup circuit or automatically resetting the circuit).

[0028] The module working power supply unit is used to provide excitation power for the artillery, and to provide working power for the artillery information conversion and simulation device.

[0029] It should be noted that the functions of the gun information conversion unit, control unit, module working power supply unit, and gun information self-checking switching unit included in the gun information conversion and simulation device can be realized by electronic circuit technology in the prior art in conjunction with a software control program. The gun information conversion and simulation device provided in this embodiment changes the current situation that the naval gun fire control system generally adopts naval gun information and gun information conversion devices of various models, realizes unified information conversion and signal transmission between the fire control computer and various types of guns on the ship, and adapts to the standardization and modularization development trend of the naval gun fire control system.

[0030] In addition, the gun information conversion channel is the key node for the transmission of gun information to the fire control computer. The accuracy and precision of gun information conversion are crucial to the naval gun fire control system. After the fire control system is powered on, the working status of the naval gun fire control conversion channel can be automatically detected at the control device end. The automatic uploading mechanism of the conversion channel working status equipped in this embodiment can upload the working data of the gun information conversion channel to the fire control computer, which can assist the fire control channel self-checking, fault diagnosis, fault alarm, and equipment maintenance of the entire naval gun fire control system.

[0031] As an optimization, the artillery information conversion unit is also used to absorb the transient reverse large current generated when the high-voltage artillery information is switched. Specifically, the artillery information conversion unit can achieve the function of absorbing the transient reverse large current generated when the high-voltage artillery information is switched through a transient voltage suppressor, an overvoltage protection circuit, an RC absorption circuit or software control. This can avoid the damage of the chip and electronic components in the artillery information conversion simulation device by the large current, and improve its service life.

[0032] As an example, the artillery information conversion unit also includes a synchronizer or a rotary transformer for converting circuits, and the input end of the synchronizer or the rotary transformer can be connected to the artillery simulation signal input end of different specifications, so that the device can choose to connect artillery of different types and specifications, thereby improving the compatibility of the ship's gun fire control system.

[0033] As an example, the excitation power supply specification is medium frequency AC or high frequency AC, and the specifications include: 2V / 2KHz, 26V / 400Hz, 36V / 400Hz, 115V / 400Hz, 26V / 2KHz.

[0034] As an example, the module working power supply unit provides ±15V and 5V DC power to the device.

[0035] As an example, the excitation power supply can convert 220V / 50Hz AC power into medium frequency 115V / 400Hz, 2V / 2KHz, 26V / 400Hz, 36V / 400Hz, 26V / 2KHz power supply, providing excitation power for the artillery excitation and the input conversion module and output conversion module in the artillery information conversion unit.

[0036] As an example, the artillery information conversion and simulation device also includes a leakage protection unit for protecting the artillery information conversion and simulation device from overcurrent and overvoltage during power-on and power-use processes.

[0037] As an example, the artillery information conversion and simulation device also includes a working status indication unit, which includes a working status indicator light for indicating the working status of the device. If the light is on, it means that the device is powered on normally.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
