Description

The invention relates to radar and can be used in mobile radar stations (radar) for monitoring airspace, for example, for detecting, measuring coordinates, identifying, tracking and recognizing targets, as well as for upgrading a radar.

Known tactical three-coordinate mobile radar circular surveillance long-range, type S 753 Martello (UK) (RadarSystemForecast, l ^st Quarter, 2003).

A well-known radar can be placed at an unprepared position, has built-in equipment for lifting and moving goods, is transported in large parts (containers, fragments of the headlamp, aerial recognition system, OPU) on any standard road trailers, the loading and unloading of which is carried out by a standard mechanical winch.

A disadvantage of a radar is its low mobility associated with its disassembled transportation on several vehicles, which leads to additional costs for disassembling and assembling the headlights, loading and unloading the transported parts of the radar, their electrical dismantling and subsequent installation.

Known mobile radar circular survey meter range (patent for utility model No. 63943, IPC class: G01S 7/00).

An increase in radar mobility and a reduction in the number of combat crews in a utility model is achieved by the fact that hinged and (or) telescopic joints between its elements and their parts are introduced into the antenna structure, the antenna is rolled up and compactly laid on the periphery of the vehicle without dismantling. The rest of the equipment is placed on the freed part of this vehicle, i.e. The entire radar can be placed on one vehicle, and in combat conditions there is a practical opportunity for quick relocation of the radar.

The disadvantage of the utility model is the lack of mobility, due to the need for manual operations for deployment and folding, laying and fixing in the transport or working position.

Known mobile circular viewing station meter wavelength range (Eurasian patent No. 007941 IPC G01S 13/04, publ. 02.27.2007). At this station, reducing the time required for coagulation and deployment and increasing mobility is achieved through the introduction of a deployment and coagulation device, a single structural solution for the antenna mast device with various types of antennas installed on it, and placement on the same vehicle. The deployment and folding device is an automated hydraulic system with mechanical elements that provides folding (unfolding) of the main antenna, compensation antenna, NTZ antenna, lowering (raising) and laying the antenna mast device AMU on the vehicle platform and its leveling when deploying the radar. At the same time, the reduced number of deployment modes and controls creates usability and does not require highly skilled operator.

In a known station, to provide power to both power and control devices used for deployment and leveling, it is necessary to connect the primary power of the product, start the diesel engine, or the nearest three-phase network, which requires additional time and accordingly reduces the radar mobility.

In addition, the automated deployment and folding system involves the use of a large number of limit switches - position sensors of antennas, the status of stoppers and other elements, which reduces the reliability of this station, since the probability of failure of one of the limit switches during its operation increases.

The closest in technical essence and purpose is the mobile three-coordinate radar of the decimeter range adopted for the prototype (RF patent No. 2394253, IPC class: G01S 13/00, published on July 10, 2010).

Known radar contains an antenna mast device, which includes a phased antenna array (PAR), a beam position switch for transmission in the elevation plane, an orientation and topographic location device, a transmitting device, a processing and control device, state identification system equipment, a rotary support device, a device deployment and coagulation, a vehicle on the platform of which all devices included in the radar are located both in working and in transport state.

The increased mobility of the known radar was achieved by placing all the components of the radar (except the primary power source) on a single vehicle, which eliminated disassembly (assembly), loading (unloading) and electrical disconnections (connections) of the components together, as well as due to the introduction of the device deployment and coagulation (URS), which reduced the time of coagulation and deployment of the antenna mast device AMU and HEADLAND, as well as the time to level the vehicle platform.

However, upon arrival at the position before deployment, additional time is required to connect the primary power of the station, for which it is necessary to start the power unit, which can be located on another vehicle, deploy power cables and connect them to the outputs of the power unit, or to the outputs of the industrial network, if necessary protective grounding, which reduces the mobility of the known radar.

In addition, high performance can only be achieved in automatic mode, and therefore requires the introduction of feedback sensors and a high-speed programmable control device. With a large number of deployable devices, for their fixation in the stowed or working position, a significant number of position sensors and stop sensors are required, as well as chains for their connection. For example, to securely fix the mast of the antenna mast device, three stops may be required, two status sensors on each and at least two mast position sensors. The same applies to column stoppers of the slewing ring, antenna-feeder system, reflector, and sensors of other devices. The total number of sensors can be two to three dozen, which increases the likelihood of failure and reduces the reliability of the automatic deployment and coagulation, especially taking into account the mechanical and climatic influences characteristic of mobile radars.

The technical result of the invention is to increase mobility by reducing the deployment and coagulation time, simplifying operations and increasing reliability by localizing failures and finding faults directly in the process of deployment and coagulation.

The technical result is achieved by the fact that in a mobile radar that includes a vehicle (TS), a slewing ring (OPU) mounted on a vehicle, an antenna column (KA) with equipment for receiving, transmitting and processing data installed on an OPU, the antenna feeder system (AFS), mechanically connected to the spacecraft, elevation guidance system (CHε), mechanically connected to the spacecraft and the AFS, azimuth guidance system (CHβ), mechanically connected to the control system, power supply system (BOT), workstation ( AWP), antenna mast the second device (AMU) with communication (AS) and data transmission (APD) antennas, leveling system equipment (ASG), deployment-collapse equipment (ARS), with hydromechanical actuators providing folding (unfolding) and fixing of antennas, lowering (raising) ) and laying the AMU on the platform of the vehicle, the deployment of the pivoting device, folding platforms (OP), fencing devices (UO), while the devices included in the radar, both in working and in transport condition, are placed on the trans According to the invention, the tailor means, the commutator and the hydraulic pump are additionally introduced into the radar, the vehicle further includes a power take-off installation, and the on-board battery is used as an alternative power source, the deployment-collapse equipment includes position and state sensors, an analysis and control device, a control panel and indications, actuators, while position and state sensors are mechanically connected to the corresponding deployable devices (OPU, AMU, A C, ADF, UO, OP) and their fixing elements, and the output circuits of the sensors are electrically connected to the first inputs of the analysis and control device, the first outputs of which are connected to the inputs of the actuators, and the second outputs are connected to the input of the control and display panel, the outputs of which are connected to the second inputs of the analysis and control device, the first and second outputs of the automated workstation are connected respectively to the inputs of the guidance system in azimuth and the guidance system in elevation, while of the vehicle’s vehicle is mechanically connected to the hydraulic pump shaft, and the output of the power supply network is connected to the first input of the switch, the second input of which is connected to the output of the vehicle’s onboard battery, and the output to the power inputs of position and state sensors, analysis and control devices, deployment equipment -collapses, azimuth guidance systems, elevation guidance systems and leveling system equipment.

At the same time, the equipment of the leveling system is made autonomously, equipped with controls, sensors and actuators operating from the hydraulic system.

The introduction of the switch allows you to control the connection of the station to the power supply system of the EPA or to the on-board battery.

Using the onboard battery of the BA allows the station devices to be turned on through the switch immediately upon arrival at the position when the power supply system of the solar power supply is not yet connected, which increases its mobility.

The analysis and control device provides automated software control of executive devices, which even with a significant number of sensors allows not only minimizing the time required to complete the deployment and folding operations, but also simplifying the operator’s work by reducing the controls.

The introduction of an analysis and control device also makes it possible to analyze a possible failure or accident, determine the malfunction of a specific sensor and, directly during operation, eliminate the indicated malfunction, which increases the reliability of the radar.

The indicators of the control and display panel show the status of the devices being deployed, and in emergency or emergency situations, a failure indication is provided accurate to a specific sensor.

Under the conditions of use of mobile radars, it is most likely that the sensor’s malfunction is a failure rather than an accident, for example, if moisture, snow or dirt gets into the gap of an inductive proximity switch, changes in the operating distance, for example, due to accidental deformation or jamming of a moving object on switch, etc. In this case, knowing the location of the failed sensor, you can quickly eliminate the malfunction even in the field.

As a result of the search, no information was found allowing to conclude that the distinguishing features of the claimed device are known, therefore, the claimed technical solution meets the novelty condition.

From the prior art it is not known the influence of the distinctive features of the claimed device on the achieved technical result, therefore, the claimed device meets the condition of an inventive step.

All devices included in the radar, both in working and in transport condition, are located on the vehicle platform.

The vehicle (TS) 1 is made on an automobile or other chassis containing a power take-off (PTO) 15 and an on-board battery 21.

The rotary support device (OPU) 2 is mounted on a vehicle and comprises a gearbox mechanically coupled to an azimuth guidance system (CHβ) 5 actuator.

The antenna column (KA) 3 is installed on the OPU 2 and contains equipment for receiving, transmitting and processing data.

Antenna-feeder system (AFS) 4 is mechanically connected with KA 3 and the output of the elevation guidance system (CHε) 6 and can be made on the basis of the PAR, or in the form of a narrow antenna with an irradiator and a parabolic reflector.

The azimuth guidance system (CHβ) 5 incorporates a digital angular position sensor, a control unit, an amplification-converting device, and an executive electric motor. The elevation guidance system (CHε) 6 can be performed similarly or using hydraulic actuators.

The power supply system (BOT) 7 in the normal operating modes of the station provides AC voltage for power devices, electric motors, fans, air conditioners, etc., as well as voltage on the DC network, to power secondary power supplies of units and other devices of the station.

The switch (K) 23 is made on the basis of a contactor controlled by voltage from the side of the network. When the station is on, voltage is present on the network side, and the switch 23 provides the station from the SEP 7 in the normal mode. When the station is off, there is no voltage onboard, and the output from the switch 23 receives voltage from the on-board battery 21 of the vehicle TS 1. The power take-off for powering the hydraulic pump 22 is carried out through the UOM 15 from the motor shaft. At the same time, all the radar units and devices involved in the deployment mode are designed in such a way as to ensure operation both from the voltage of the onboard network 27 V and from the voltage of the onboard battery 24 V. In particular, for example, power supply modules of type СПН27 can operate in the input range voltages from 17 to 36 V.

Coagulation Deployment Equipment (APC) 14 is an automated control system for hydraulic mechanisms for raising, lowering and fixing deployable devices and includes position and state sensors (DPS) 16, analysis and control device (UAU) 17, actuating devices (IU) 19, control panel and indications (ISP) 18.

The position and state sensors (DPS) 16 are mechanically connected with the corresponding deployable devices and can be performed, for example, on the basis of an inductive proximity switch VTI. 1246.1.

The control and display panel (PUI) 18 contains toggle switches that provide the formation of commands for deployment, collapse, control, as well as indicators that display information about the current mode and the results of auto control. The toggle switches and indicators of the ISP 18 are not shown in the diagram.

The analysis and control device (UAU) 17 is based on the microcontroller and provides an analysis of the signals of the sensors 16 and program control of the actuators 19 by commands from the ISP 18, as well as the issuance of current mode information and the results of auto monitoring on the indicators of the ISP 18.

Actuators (IU) 19 can be performed, for example, based on hydraulic mechanisms with proportional or relay control. The pressure in the hydraulic system when deploying and collapsing without connecting the primary power to the station is provided by the hydraulic pump 22. In the normal mode, a pump with an electric motor can be connected, for example, based on a three-phase asynchronous motor powered by the SEP 7 (not shown in the diagram). DUTs provide folding (unfolding) and fixing of antennas, lowering (raising) and laying AMU on the vehicle platform, deploying the slewing ring device, folding platforms (OP), fencing devices (UO),

The antenna-mast device (AMU) 8 is structurally placed on the vehicle chassis of the vehicle 1 and contains a mast, a communication antenna (AS) 9 and a data transmission antenna (ADF) 10, and may also contain other functional devices that are brought into operation when deployed station.

The fencing device (UO) 11 and the hinged platform (OP) 12 provide emergency mode locking, personnel safety and convenience during setup.

The hydraulic pump 22 is based on a hydraulic motor connected directly to the output shaft of the power take-off installation 15 of the vehicle 1.

The equipment of the leveling system (ASG) 13 is made autonomously, has its own control panel, sensors and actuators operating from the same hydraulic system.

Workstation (AWP) 20 is a PC-based operator console. AWP 20 manages station systems in normal operation.

The output circuit of the position and state sensors (DPS) 16 is connected to the first inputs of the analysis and control device 17, the first outputs of which are connected to the inputs of the actuators 19, and the second outputs to the inputs of the control and display panel 18, the outputs of which are connected to the second inputs of the analysis device and controls 17. The shaft of the power take-off installation 15 of the vehicle 1 is mechanically connected to the hydraulic pump shaft 22. The output side of the power supply system (BOT) 7 is connected to the first input of the switch 23, the second input of which is connected to the output of the on-board battery 21 of the vehicle 1, and the output to the power inputs of the devices of the deployment-coagulation equipment 14, the azimuth guidance system 5, the elevation guidance system 6 and the leveling system equipment 13. The first and second outputs of the workstation 20 are connected respectively to inputs of the guidance system in azimuth 5 and guidance system in elevation 6.

The radar operates as follows.

Upon arrival at the position, the primary power of the station ~ Uп is not connected and there is no voltage onboard the network. The voltage of the onboard battery BA 21 through the switch 23 is supplied to the power inputs of the blocks and devices necessary for operation in deployment mode. When you turn on the power take-off mode of the vehicle 1, the hydraulic pump 22 is turned on, connected to the shaft of the UOM 15, and provides the necessary pressure in the hydraulic system. The position and state sensors 16, mechanically connected with the deployable devices (OPU 2, AMU 8, AC 9, APD 10, UO 11, OP 12), and their fixation elements, provide the necessary information on the current position of these devices to the microcontroller UAU 17 and condition of stoppers.

On the indicators of the ISP 18, the stowed position of the AMU mast 8, communication antennas 9, data transmission antennas 10, and other devices not included in the AMU 8 (UO 11, OP 12, KA 3 with OPU 2), as well as the status of the stoppers fixing the indicated devices. When you turn on the switch DEVELOP., The control panel and display 18, the analysis and control device 17 starts the deployment program recorded in the memory of the microcontroller. UAU 17 generates the corresponding control signals for actuators 19, the hydromechanisms of which provide sequential unlocking of the stoppers, the lifting of the mast AMU 8, the deployment of antennas and other devices. Sequential execution of operations is also displayed on the indicators of the console 18. The deployment ends with fixing these devices in the working position.

Similarly, in the reverse order, the collapse program is executed when the SVERT switch is turned on. remote control 18. During operation, UAU 17 analyzes the operation of the program and if the sequence of operations, timing, violation of sensors or other failures are violated, the program stops. If at the same time the CONTROL of the remote control 18 is turned on, then information about the malfunction is displayed, for example, the number of the malfunctioning or malfunctioning sensor.

Thus, the station is ready for deployment immediately, as soon as the switch of the power take-off installation 15 of the vehicle 1 is turned on and the on-board battery 21 is connected.

Deployment, folding and leveling operations can also be performed when the station is on, in which case the station devices are connected to the board of the SEP 7 through the switch 23 and the station is collapsed from the operating mode by the operator signal from the AWP 20 to the inputs of the azimuth guidance system 5 and guidance systems in elevation 6, pre-automatic installation in the transport position in azimuth of the slewing ring 2 with the antenna column 3 and antenna-feeder system 4 in elevation, which allows Flags simplify and speed up coagulation work. After the signals of the sensors of the stowed position OPU 2 and AFS 4 are received at the inputs of UAU 17, their fixation and further coagulation are allowed.

The advantage of the proposed mobile radar station is to increase mobility by reducing deployment and coagulation time, simplifying operations and increasing reliability by monitoring the radar in these modes and indicating the location of the malfunction directly during deployment and coagulation.

The equipment of the leveling system (ASG) during deployment is also powered by UOM and BO, but has its own remote control. If there are no design limitations and safety requirements are met, this allows you to level out simultaneously with the deployment of AMU and, thus, further reduce the total deployment time of the station.

An additional advantage is also the possibility of software development for the purpose of application in similar products with a different range of deployable devices and a different procedure for their deployment.
