Description

 The invention relates to computer technology, namely to automated control systems for anti-aircraft missile forces, and can be used in the air defense forces of the country as a system for generating control actions for anti-aircraft missile forces based on the results of processing radar information from several sources.

A known system called "Control Center SAM" PATRIOT ", AN / MSQ-104, containing a device for interfacing with a radar, a primary processing processor, a central processor and a display device [1]
This system cannot work in combination with a radar located in close proximity to it. The disadvantage of this system is its inability to work with several consumers of radar information of various types of data transmission equipment.

 The prototype of the invention, the system "Control Center ACS grouping SAM" AN / TSQ-73 [2] containing a device for interfacing with discrete channels, an input / output device, a storage device, a device for super-memory, a central processor, a control device and a display device that is connected by two-way communication with a central processing unit.

 The disadvantage of this system is the difficulty of moving the display device outside the system, due to the large volume and weight of the connecting cable. (The removal of the display device is determined by ensuring safety and improving the working conditions of staff). This leads to a significant increase in the deployment and deployment time of mobile systems. In addition, the coaxial cable used in the known system for connecting a remote display device has low resistance to the influence of various factors of weapons of mass destruction, which can lead to rapid destruction of the system. In addition, the coaxial cable has insufficient noise immunity from electromagnetic fields, which leads to instability in the display of information.

 The proposed structure allows the use of a fiber-optic path for transmitting radar information to a display device outside the system, which significantly reduces the deployment and deployment time of a mobile system, increases its service life and stability of information display.

 All the blocks that make up the optical converters are built according to well-known principles.

 Each VOSPI channel is formed by two duplex subchannels: information and control.

 The information subchannel includes a first cable coordinator 12 and a first optical transmitter 13 of the optical converter of the first group 11 connected in series, a fiber optic cable, a first optical receiver 27 and a first cable amplifier 28 of the optical converter of the second group 26; and serially connected the first cable coordinator 29, the pulse-width manipulator-demanipulator 30 and the first optical converter 31 of the optical conversion of the second group 26, the fiber optic cable, the first optical receiver 14, the pulse-width manipulator-demanipulator 15 and the first cable amplifier 16 of the optical converter first group 11.

 To transmit signals over one channel, one four-wire cable of the type KVSP-60-4 / 4 is used. Thus, the fiber optic path 25 consists of three fiber optic cables, and a separate light guide fiber is used for each transmission direction of each subchannel.

 A quartz optical fiber is used as a signal propagation medium in a fiber optic cable. The light guide fiber consists of a core with a diameter of 60 μm and a shell with a diameter of 150 μm made of quartz glass, and the refractive index of the core is greater than the refractive index of the shell. The propagation of light pulses along the light guide fiber occurs in the core due to the effect of total internal reflection of light rays from the interface between the core and the sheath.

 The inputs and outputs 40, 41, 42 of the system are connected to the telecode channels designed for: inputs and outputs 40 for communication of the system with sources of radar information; inputs and outputs 41 for communication with neighboring systems that perform a function similar to the function of the claimed system, which provides the ability to control neighboring systems in the event of failure of their central processor; inputs and outputs 42 for communication with anti-aircraft missile forces.

 The proposed computing system for automatic control of anti-aircraft missile forces works as follows.

 In the mode of receiving information at the input 40 of the system receives radar information from several sources. The information is supplied to the device 1 for interfacing with discrete channels, in which, simultaneously with storing the fact of the arrival of pulses of the clock frequency of the reception, the received bit of information is recorded. The device 1 for interfacing with discrete channels generates a request to the device 6 of the control, which ensures the start of the device 5 of super-operative memory to process the received bit of information, after which the device 6 of the control issues an address to the device 1 for interfacing with discrete channels and ensures the transmission of the received bit of information to the device 5 of the super memory. The accumulated information on the signals from the control device 6 is transmitted to the storage device 4, where the accumulation of finished in meaning blocks of information. The information stored in the storage device 4, according to the signals of the control device 6 is transmitted to the Central processor 2 through the device 3 input-output. In the central processor 2, all the received information is processed and fed to the first interface device 9, where it is amplified, branched into two directions and transmitted to the first display device 7 to the operators controlling the tracking of air objects and to the fiber optic system. Information and control signals from the pairing device 9 are fed to the optical converter 11.i corresponding to this channel.

 Information is transmitted on one channel as follows. Information signals are fed to the cable coordinator 12 of the optical converter of the first group 11 and then to the optical transmitter 13, where the conversion of the electrical signal into an optical one takes place. The signal passes through the corresponding optical fiber of the optical cable of the fiber optic path 25 and is fed to the input of the optical receiver 27, which is part of the optical converter of the second group 26, where the optical signal is converted into electrical signal. Next, the signal passes through the cable amplifier 28 and enters the second device 10 interface.

 The control signals from the first interface device 9 are fed to the cable coordinator 17 of the optical converter of the first group 11 and then transmitted to the seal 18. In the seal 18, they are linked to the VOSPI clock network, their transmission priority is established, parallel-serial conversion and formation of the compressed signal are performed. From the output of the seal 18, the signal enters the encoder 19, where it is converted into a bi-pulse form (in the Manchester code) according to the table.

Next, the code signal is sent to the decoder 33, where the clock frequency is allocated and decoding. From the output of the decoder 33, the signal is fed to the splitter 34, where the series-parallel conversion, the formation of the durations and the mutual arrangement of the output signals are carried out. The latter pass through a cable amplifier 35 and enter through a second interface device 10 to a remote display device 8.

 In the mode of issuing information to telecode channels, the system operates as follows.

 Command information from the display device 8, passing through the interface device 10, is fed to the second group 26 of optical converters. In this case, information signals are transmitted through the information subchannel of each channel, and control signals along the control channel.

 The information signal and the accompanying clock signal are fed to the cable coordinator 29 of the optical converter of the second group 26 and then to the pulse-width manipulator-demanipulator 30, from the output of which the signals are fed to the input of the optical transmitter 31. The manipulation process leads to the combination of both signals into one, while the carrier signal is the clock signal accompanying the information signal, which is modulating. From the output of the optical transmitter 31, the signal through the optical cable of the fiber optic path 25 is fed to the input of the optical receiver 14 of the optical converter of the first group 11 and then to the pulse-width manipulator-demanipulator 15. From the demanipulator, two information signals and the accompanying clock signal are sent to the cable amplifier 16 and further to the first interface device 9.

 The technical result of the invention is as follows.

 VOSPI provides a duplex exchange of information through three independent channels in accordance with the requirements of the 5E26 interface between the central processor and remote display devices. For the channel and subscriber side, a unified interface device (US) is used. Installation of the unit in the "Channel" or "Subscriber" mode is carried out using the appropriate switches. In CSS, logical processing of interface signals, the conversion of electrical signals into optical form, as well as the inverse transformation are carried out.

 The signals of each interface channel 5E26 are broadcasted on the corresponding VOSPI channel formed by two duplex subchannels: information and control.

 The information subchannel is used to transmit SHIN-K (from channel to subscriber), SHIN-A and IS-A (from subscriber to channel) signals. All other interface signals are transmitted over the control subchannel.

 To transmit signals over a single channel, one four-core fiber-optic cable is used.

 The block diagram of the connection of the fiber-optic cable to the OPDM-2 optical transmitters and OPRM-2 optical receivers is shown in Fig. 2 (optical connectors with a radiator are part of the OPDM-2 optical transmitter, and optical connectors with a photodiode are part of the OPRM-2 optical receiver 2).

a) information subchannel
The transmission rate on the information subchannel is 375 kbit / s, the code is single-pulse.

 The subchannel operates in operating or test modes. In working mode. In the direction of the subscriber channel, the SHIN-K signal is transmitted through the information subchannel. It comes from the channel side to the US-K, goes to the agreed 75-ohm load of the cable coordinator (KS) and then to the optical transmitter OPDM-2. Here, the conversion of an electrical signal into an optical one takes place. The signal passes through the corresponding fiber-optic fiber of the wok optical cable and enters the input of the optical receiver OPRM-2 US-A already on the subscriber's side. Once converted to electrical form, the signal goes to the cable amplifier and then to the subscriber.

 In the direction of the subscriber-channel, the SHIN-A and IS-A signals are transmitted through the information subchannel. Both signals on the subscriber side are fed to US-A. Here they go to the cable coordinator and then to the pulse-width manipulator-demanipulator (PWM-DM). From the output of the PWM-DM are fed to the input of the optical transmitter OPDM-2. The manipulation process leads to the combination of both signals into one, while the IS-A signal serves as the carrier, and the modeling signal is BUS-A. From the output of the OPDM-2 optical transmitter, the signal is transmitted through the VOK optical cable to the channel side, fed to the input of the OPRM-2 US-K optical receiver, and goes to the pulse-width manipulator-demanipulator. From the PWM-DM demanipulator, the SHIN-A and IS-A signals go to the cable amplifier and then to the channel.

b) control subchannel
To transmit signals over the control subchannel, address and positional multiplexing is used. The transmission rate of the compressed signal is 8 Mbps, the code is bi-pulse.

 The subchannel operates in operating or test modes. In the operating mode, the PA-K, NA-K (4p), NA-K (5r), OST-K, NU-K1, NU-K2 and MV interface signals are transmitted in the direction of the channel-subscriber through the control subchannel.

 All these signals arrive at the cable coordinator US-K and then follow to the sealant. In the sealant, they are linked to the VOSPI sync frequency grid, the priority of their transmission is established, parallel-serial conversion and the formation of the compressed signal are carried out. From the output of the seal, the signal goes to the encoder, where it is converted into a bi-pulse form (in the Manchester code).

 The code signal goes to the optical transmitter OPDM-2 and passes through the optical cable to the optical receiver OPPR-2 US-2. Next, the code signal is transmitted to the decoder, where the clock frequency is allocated and decoded. From the output of the decoder, the signal is fed to the splitter, where the series-parallel conversion is carried out, the formation of durations and the mutual arrangement of the output signals. The latter pass through the cable amplifier to the output of US-A.

 In the direction of the subscriber-channel, the signals are transmitted on the control subchannel: TRB-A1 (ZAN-A1), FAULT-A, TRB-A2 (ZAN-A2), VO-A, IZ-A.

 These signals arrive through the cable coordinator US-A to the sealant, encoder, optical transmitter OPDM-2 US-A and through the fiber-optic cable enter US-K. Then they go through the optical receiver OPRM-2 US-K to the decoder, splitter and through the cable amplifier to the US-K output.
