Description

The invention relates to devices for inputting data into control devices for underwater vehicles.

It is known that both autonomous and remotely controlled unmanned underwater vehicles (UUVs) for various purposes are widely used in the fleets of the leading maritime powers. All of them have on-board control devices necessary for solving problems inherent in each type of UUV. Depth and multiplicity instruments, heading instruments (Aubrey) and distance instruments, sinking instruments, urgency instruments, swimming instruments, and others have been used as control devices for some UUVs, for example, torpedoes and mines [1, p. 337-338].

Before starting from the carrier, a route assignment is introduced into the indicated devices of the NPA. The entry of the route assignment is carried out manually or remotely, when the UUVs are placed in launching devices, which can be located on board the carrier, and overboard. To develop a route assignment, computing and deciding control devices of the carrier are used, and to enter it into the control devices of the NLA - devices for electromechanical or manual data entry [1, p. 338]. So, for example, with the advent of torpedoes and mines, data entry into their control devices was carried out manually by turning the setting heads of the course device. Later, electromechanical devices for remote data entry appeared - spindle devices (from it. Spindel - a spindle, a shaft having right and left rotation revolutions), which are placed on a launcher or torpedo tube. They include a device for turning the spindle (s) at an angle corresponding to the data generated by the control devices. To enter data into the NLA from the spindle device, the spindles must be lowered, articulated with the setting heads of the control devices and rotated to the required angle. Before starting the NPA, the spindles must be lifted in order to exclude their breakage. The spindles are usually lifted with compressed gas supplied through the gas line (pipeline).

The use of spindle devices solved the problem of remote data entry into the ROV, but seriously complicated their operation, since there was a risk of deformation of the spindles during loading, unloading and starting of the RV, the probability of data entry errors increased due to improper articulation of the spindles with the installation heads of the RV control devices due to carelessness of the service personnel. In addition, the input of data into the control devices of the UFO is limited by the capabilities of the mechanisms for turning the spindles by angles and speed. So, the time of data input by the spindle device ranges from 3 ... 10 s in automatic mode to 5 ... 20 s in manual mode. Inconveniences in the operation of spindle devices are also added by pipelines supplying compressed air or powder gases to the spindle lifting mechanisms.

There are electromechanical devices for entering data into control devices of the NLA, using various electrical connectors, for example, AERVD-100 - an electrical breaking waterproof remote unit operating both in air and in water [2, p. 2], [3]. The use of electrical connectors allows transferring digital information and reduces the time of its input to 1 ... 1.5 s. At the same time, the use of electrical connectors is not without drawbacks - their weak point, like in spindle mechanisms, is the need for accurate contact mating and ensuring tightness for working in water. When docking and undocking the UVA with the electrical connector of the launcher, care must be taken to prevent deformation of the contacts, which are also subject to the corrosive effects of sea water and powder gases. In addition, the abundance of plug-in cables requires careful handling.

The indicated disadvantages of electromechanical and electrical devices for entering data into control devices of the NLA potentially reduce the efficiency of their use.

Along with contact devices for the exchange of information between objects, there are contactless devices. One of them is the infrared port (IrDA) of the Infra Red Data Association - IrDA, which is a type of fiber-optic short-range communication line and is a group of standards that describe the protocols of the physical and logical layer of data transmission using information as a transmission medium. infrared range of light waves [5]. IrDA infrared port realizes two-way communication between objects at a distance of up to 1 m using infrared radiation with a wavelength of 850-900 nm in the "point-to-point" mode [5]. There are several types of IrDA devices that transmit data at a rate depending on the IrDA specification (Table 1).

The lowest speed available for the infrared port is 9600 bps, which allows remote transmission of data to an object and their control in a fraction of a second. The FIR and VFIR specifications represent the "golden" mean in terms of performance and cost, as they have excess speed in relation to the amount of information required for control devices of the UUV. The infrared data input port has a large upgrade resource and, in the future, will make it possible to transfer practically any type of data, from large arrays of numerical or textual information to photos and even video files [5].

The infrared port device includes a pair consisting of an infrared emitter (LED) and an infrared receiver (photodiode) located on each side of the communication line. The presence of a transmitter and a receiver on each side is necessary to use two-way communication protocols. The LXHL-NE98 LED is used as a transmitter in the IR port, and a PD256 photodiode is used as a receiver. The wavelength they use in the blue-green range is best suited for transmitting information in the aquatic environment.

The described device for contactless two-way data transmission between two objects (correspondents) is taken as a prototype of the invention. The device includes a transmitter (emitter) and a receiver on each side of the communication line, a current source, input and output amplifiers, a pulse frequency modulator, a comparator and an inverter [5]. The communication line between objects (correspondents) can be both radio-technical and optical, depending on the environment: if it is water, then an optical communication line with an infrared or blue-green range is used, if the air is radio-technical.

The current source powers the circuit of the contactless data transmission device, the amplifiers serve to amplify the input or output signals generated by the pulse frequency modulator. The comparator "cuts" the signal and converts it to a rectangular form, and the inverter inverts the signal having a negative amplitude [5].

The disadvantage of such a device is the impossibility of its use for inputting data from control devices of a ship or a vessel into control devices of an NPV located in a launcher in an air or water environment. It does not provide for the possibility of receiving and transmitting data to objects located in different physical environments, in conditions of sharp pressure surges and the aggressive effect of combustion products of combustible substances.

The aim of the invention is to develop a device for contactless data input into control devices of an unmanned underwater vehicle and data exchange of its devices with control devices of the carrier (ship, ship or aircraft).

To achieve the object of the invention, a device for contactless data input into control devices of an unmanned underwater vehicle is proposed, including a radio or optical communication line of control devices of a carrier with control devices of an unmanned underwater vehicle, having on each side a current source, input and output amplifiers, a frequency-pulse modulator, a comparator , an inverter, a transmitter and a signal receiver, characterized in that, in addition, the section of the carrier communication line has a sealed connector located on the launcher, through which the transmitter and the signal receiver inside the launcher are connected to the control devices of the carrier, the receiver and transmitter of the carrier have a protective shutter and its control device, as well as sensors transmitting information about the closed or open position of the protective shutter to the control devices of the carrier.

The sealed connector serves to separate the environment of the carrier's premises from the environment in the launcher and ensures the integrity of the carrier's communication line connecting its control devices with the receiver and transmitter inside the launcher.

The protective shutter protects the receiver and transmitter of the carrier, which are inside the launcher, from the aggressive effects of the environment during the operation of the UVV: pressure and temperature surges during the launch of the UUV, as well as contact with sea water and powder gases. At the time of starting the UUV with the help of the protective shutter control device, it is closed and the receiver and transmitter are protected from the specified influences. To close the shutter, the force of the pressure of the compressed gas supplied through the pipeline is used. After the UAV leaves the launcher and the gas pressure drops, the protective shutter returns to the open position under the action of the spring. The sensors for opening / closing the protective shutter are electrical contacts that close the circuit and transmit information about the closed or open position of the protective shutter to the control center.

The operation of the device for contactless data input into the control devices of an unmanned underwater vehicle is illustrated in the following figures:

- fig. 1 - placement of an unmanned underwater vehicle in the launcher;

- fig. 2 and 3 - operation of the protective shutter control device;

The numbers indicate: 1 - launcher, 2 - front cover of the launcher, 3 - rear cover of the launcher, 4 - NLA, 5 - compartment with NLA control devices, 6 - NLA transceiver unit with a receiver and transmitter of a non-contact data input device, 7 - transceiver unit of the carrier with the receiver and transmitter of the contactless data input device, 8 - sealed connector, 9 - protective shutter, 10 - piston with spring of the safety shutter control device, 11 - chamber for filling compressed gas of the safety shutter control device, 12 - cable of the contactless input device carrier data, 13 - pipeline for compressed gas inlet to the protective shutter control device.

FIG. 2 and 3 illustrate the operation of the privacy shutter control device. FIG. 2 shows the location of the protective shutter in the open position. When starting the NPA, compressed gas enters (14) into the chamber (11), acts on the piston with a spring (10) and moves the protective shutter (9) to the closed position (Fig. 3). As a result, the transceiver unit of the carrier (7) with the receiver and transmitter is protected from the damaging effects of increased pressure, temperature or powder gases.

FIG. 4 shows a schematic diagram of an optical communication line used in cases when the radio technical communication line does not work, for example, when the UUV is in the water environment. The numbers in figure 4 show: 15 - input voltage, 16 - input amplifier, 17 - pulse frequency modulator, 18 - output amplifier, 19 - LED, 20 - photodiode, 21 - comparator, 22 - inverter, 23 - output voltage.

The technical result of the invention is a device for contactless data input into control devices of an unmanned underwater vehicle located in the launcher on board or outside the carrier. It allows you to enter data into an underwater vehicle and receive response information from it, while greatly simplifying the operation of various types of underwater vehicles due to the rejection of similar spindle and electromechanical devices.
