Description

The utility model relates to information-measuring equipment, namely to means of digital recording of parametric, speech, video or other data in a solid-state non-volatile information storage device, and can be used in ships and vessels for recording office telegraph and telephone traffic. In this case, the utility model can be used both autonomously and as part of the automated ship communication systems of the "Rokot" type.

A device for inputting information for writing data to a solid state drive is known (RF patent No. 2097825, G06F 3/06, 1996), containing a pre-processing unit, the inputs of which are the inputs of the device, connected by two-way communication with a microcomputer, an indication circuit for the amount of information, a memory block, also connected by two-way communication with the microcomputer, a power control unit connected to the power supply unit, and a power control circuit for generating a signal to interrupt the recording of the recorded information when the supply voltage drops below the permissible value. The memory block in the device is made removable in the form of a memory card.

To record flight information on a memory card after power-on, input parallel information codes, accompanied by clock pulses, are fed to the input of the information pre-processing unit, where they are gated (synchronized), preliminary byte-by-byte packing and buffering of input information is performed, and, as it arrives, they are recorded in turn to one of the two random access memory (RAM) until they are full. Then, using the processor and controller included in the microcomputer, the recorded information is read from the RAM, checked and written as a file to the device memory block (drive) until it is full, after which the recording stops. In this case, the device state is visualized on the indicators of the front panel of the device case, and the amount of memory block filling (as a percentage of its total volume) is displayed by the information volume indication circuit.

This recording device allows you to slightly increase the speed of data recording and simplify the process of their further processing, as well as control the possible recording time in order to avoid information loss. At the same time, the possible amount of information recorded in this device is limited by the technical characteristics (volume) of the memory card, and during a long flight of the aircraft, it may be necessary to replace it, which reduces the functionality of the recording device.

A device for digital recording of information is known, implemented in the form of a solid-state on-board drive of the TBN-K-4 type (see the Technical Operation Manual MIVYU.794121.003, NPO Pribor JSC, 1998). The storage medium in this device is also an electronic memory card. At the same time, information from each input of the device is recorded in separate memory blocks of the drive corresponding to them with information arrays of a certain length. After each memory block is filled, the recording of information continues to replace the previously recorded information with the formation of a so-called ring. To mark the end of the record in the ring, after each array of information is recorded, an array of units is written, the length of which significantly exceeds the array of useful information (in particular, with a length of the useful information array of 512 bytes, the length of the array of units is approximately 2 kilobytes); at the same time, each next array of information and the array of units accompanying it are written instead of the previous array of units.

Thus, in the record of information received from each input, there is a single array of ones related to the last recorded array of information, which allows, when the drive is powered on, to detect the end address of the previous record by finding the array of ones.

After turning off the power of the drive for one reason or another and then turning it on, the recording of the next array of information in the memory block continues from the place where the previous recording was interrupted. In this case, the initial address of the array of ones is first found in the memory block, and, starting from this address, an array of zeros with a length of 512 bytes is written to mark the beginning of the recording of this inclusion, and then the next array of information.

This device has two inputs for receiving information and contains a signal conditioning and generation device designed for preliminary processing of incoming information, connected by two-way communication with a microcomputer, as well as a device status indicator and a power supply unit with its control circuit. From the output of the microcomputer, which includes a processor and a controller connected by an internal bus, the recorded information is fed into a solid-state drive (on an electronic memory card), in which memory blocks are allocated according to the number of device inputs.

However, in such a device, the need to write an array of units after registering each array of information reduces the actual recording speed. At the same time, there is no possibility of reducing these losses by increasing the length of the information array, since if the power is turned off unexpectedly, all data prepared for recording, but not recorded on the electronic card, is lost, i.e. the longer the set array of useful information, the more data can be lost. Reducing the length of the units array is also impossible, because this length is determined by the need to distinguish the record boundary from the maximum possible sequence of ones in the payload.

In addition, after the power is turned on, in order to determine the starting address for writing new data arriving at the drive inputs, it is necessary to search for an array of ones in each memory block. With an increase in the capacity of electronic memory cards, the search time for this array of units, that is, the time to bring the device to a state of readiness for operation, proportionally increases, and for capacity values of more than 1 GB, it can reach tens of minutes. This is unacceptable from the point of view of its functional purpose and thus limits the possibility of using high-capacity electronic memory cards in a known device.

One of the shortcomings of the known device is the inability to directly, without decoding the accumulated information, synchronize in time data arrays recorded from different inputs of the drive. In addition, the recording of data on an electronic memory card is not accompanied by the recording of any additional data that establishes the correctness of this recording, which can lead to an uncontrolled decrease in the reliability of the recording.

The closest in technical essence to the claimed technical solution is utility model No. 34 244 "DEVICE FOR RECORDING DIGITAL INFORMATION", IPC G01D 9/00 (2000.01), G06F 3/06 (2000.01), published on November 27, 2003 Bull. No. 33.

Utility model No. 34,244 solves the problem of increasing the speed of writing information to a solid state drive, reducing the time it takes to search for the recording boundary after turning on the power, synchronizing data arrays, and increasing the reliability of information recording.

To do this, in a device for recording digital information, containing a block for preliminary processing of information with one or more inputs that are inputs of the device, a microcomputer connected by two-way communication with the block for preliminary processing of information, a solid-state storage device with memory blocks allocated in it according to the number of inputs of the device, connected by two-way communication with the output of the microcomputer, and a power supply unit, the solid state drive is equipped with an additional search memory block formed in it, connected by two-way communication to the microcomputer and designed to search for the end of the previous record by recording service information in the form of a drive enable number and the address of the start of recording with the implementation ring records.

At the same time, the solid-state information storage device is made in the form of an electronic memory card on flash memory chips, and the microcomputer is made in the form of a processor connected by two-way communication to the controller.

The information pre-processing unit in the device is made in the form of receiver-converters in the amount corresponding to the number of device inputs connected to the exchange controller connected by two-way communication with the buffer device, and the register of status signals, the input of which is connected to the exchange controller output.

In addition, to control the technical condition of the drive, it is additionally equipped with an error memory block formed in it, which is also connected by two-way communication with the microcomputer.

A disadvantage of the known device for recording digital information, which is a prototype, is the relatively low reliability of the safety of the recorded digital information, due to the fact that all digital information is stored on one solid state storage device, the failure of which leads to the loss of all information coming from all inputs of the device for recording digital information.

At the same time, the limited memory capacity of a solid-state drive of information suggests that in the process of recording new information, erasing previously recorded information. Also, it does not provide for the prompt removal of information recorded on one of the inputs, without violating the operating conditions of the device as a whole.

The prototype device does not have a redundant power supply, which also reduces its reliability during standalone operation.

The technical objective of the claimed utility model is to increase the reliability and quality of the recorded information, as well as to increase the reliability of the device for recording digital information during its autonomous operation, through the use of a network construction architecture.

The set technical task is achieved by the fact that in a device for recording digital information, made using Ethernet network technology with several inputs, which are the inputs of a device containing a power supply, a status indicator, an exchange controller, to which a solid-state drive is connected, made in the form of an electronic memory card on flash memory chips, connected by two-way communication with the microcomputer, an additional backup power supply is introduced, and the exchange controller and memory card are structurally placed in the digital recording cell, and the number of digital recording cells corresponds to the number of independent inputs of the device for recording digital information, and since each cell digital recording has two independent channels, then each input of the device for recording digital information has two channels, the digital recording cells are structurally located in the block of expansion modules, each digital recording cell is removable and is connected to the the common bus to which the microcomputer is connected, structurally, the Ethernet switches, the common bus, the microcomputer, as well as the main and additional power supplies are located in the cross-board, and the computing module of the control unit is connected to the common bus through the Ethernet switch, to the connectors of which a status indicator is connected, made in the form of a display, a touch interface for controlling the digital recording device and a built-in speaker, a constructive computing module of the control unit with an Ethernet switch, as well as a display, a touch interface and a built-in speaker are located in the control unit of the digital recording device, and the communication controller with peripheral devices is included structurally into a block of expansion modules and is connected to the common bus of the backplane.

Comparison with the prototype shows that the proposed device is characterized by the presence of new blocks and their connections between them. Thus, the claimed device meets the criterion of "novelty". Comparison of the proposed solution with other technical solutions shows that the listed elements used in the blocks are known, however, their introduction in the specified connection with the rest of the elements leads to the solution of a new problem of increasing the reliability of the recorded information, as well as increasing the reliability of the device for recording digital information when its stand-alone location. This confirms the compliance of the technical solution with the criterion of "significant differences".

The device for recording digital information structurally consists of a control unit 1; backplane 2 and a block of expansion modules 3 (hereinafter, see Fig. 1).

In turn, the control unit 1 contains in its composition the computing module of the control unit 4 with specialized software designed to control the ultrasonic generator; Ethernet switch 5 for communication with a common bus 6 from backplane 2; touch interface 7, designed to control the settings of the UZCI; display 8, designed to display service information; built-in speaker 9, designed to listen to the recorded digital information.

The computing module of the control unit 4 can be implemented on a single board computer using SMARC (Smart Mobility ARChitecture) technology, see SMARC 2.1 Specification 2020-03-23. Expansion and configuration tools are implemented on the carrier board. The SMARC module and the carrier board together provide "computer on one board" functionality.

Specialized software implements the control of all functions of the UZCI: interface display; access control; work with the catalog of records; listening to records; time synchronization with external sources; settings of all parameters; provision of remote work protocols; output of diagnostic information and logs; uploading data to USB.

The software may run, for example, under a Linux operating system. The control of the functions of the UZCI in the main mode is carried out using the touch interface 7, located on top of the display 8.

The implementation of touch interfaces located on top of the display are known. (for example, see Mukhin I. A. Touch screens - problem solving (10 technologies). “BROADCASTING Television and radio broadcasting”: part 1 - No. 3 (55) May 2006, p. 50-52; part 2 - No. 4 ( 56) June-July 2006, pp. 40-41; Part 3 - No. 7 (59) November 2006, pp. 64-66).

The implementation of Ethernet switches is known (e.g., Brian Hill. Chapter 9. Switch Basics // The Complete Cisco Reference = Cisco: The Complete Reference. - Williams. - P. 1088. - ISBN 0-07-219280-1) .

In turn, the cross-board 2 contains in its composition a common bus 6, designed to synchronize the internal local area network of the OCD; Ethernet switches - 10.1 ... 10. N , designed to connect the YCL 14.1 ... 14. N to a common bus 6; power supply units 220 V 11 and power supply unit 12 V 12, providing power supply to the UZCI both as part of the automated ship communication systems of the Rokot type, and in stand-alone mode; microcomputer 13, designed to control the internal local network and switching YCL 14.1 ... 14. N from the block of expansion modules 3.

The cross-board is made in the form of a printed circuit board with connectors for installing equipment.

The implementation of cross-boards is known (see GOST R 50304-92).

Microcomputer 13 and Ethernet switches - 10.1 ... 10. N provide control of the used backplane cell, assignment of a network address to it in the internal network. In addition, the microcomputer provides control over the operation of power supplies (switching on, off, reboot).

The implementation of a microcomputer is also possible on the microcontroller MCU (see Novikov Yu. V., Skorobogatov P. K. Fundamentals of microprocessor technology. A course of lectures. - M .: Internet University of Information Technologies, 2003. - ISBN 5-7163-0089-8) .

The implementation of Ethernet switches - 10.1 ... 10. N is similar to the Ethernet switch 5.

In turn, the block of expansion modules (3) in its composition contains removable YaTsZ 14.1 ... 14. N , which, in turn, are structurally built-in exchange controller and memory card.

Each of the JCL provides: synchronization of work with the computing module of the control unit 4; digitization of analog audio information and its coding; maintaining a built-in catalog of records; checking the consistency of the directory and record files; receiving commands from the computing module of the control unit 4 and issuing telemetry data to it.

To implement these functions, each removable YCL 14.1 ... 14. N can be implemented in the form of single-board computers, including a computing module built using SMARC technology and specialized software running under the Linux operating system. Direct recording in each JCL is performed on a solid-state drive in the form of a flash memory. The external input of each JAM has 2 channels, which are fed with telephone and telegraph signals intended for recording. Thus, input 1 contains channel 1.1 and channel 1.2, input 2 contains channel 2.1 and channel 2.2, input N contains channel N .1 and N .2.

The total number of connected NCLs is determined by the technical capabilities of the backplane. For example, the product "Poseidon UTSZ-1" uses 12 NCRs, which provides the possibility of simultaneous recording of up to 24 channels, see the flyer for the digital recording device "Poseidon UTSZ-1".

The inventive device UZCI works as follows.

After turning on the power supply 11 and setting the operating mode of the UZCI, selecting the appropriate channel and the corresponding input of the YCL 14.1 ... 14. N , through the touch interface 7 on the display 8, in the computing module of the control unit 4, the corresponding control commands are generated, which are sent via the Ethernet switch 5 to the microcomputer 13 connected to a common bus 6. Through a common bus 6, microcomputer 13 through Ethernet switches 10.1 ... 10. N gives control commands to the YCL 14.1 ... 14. N , preparing them for operation.

Telephone and telegraph information entering the YCL 14.1 ... 14. N through the recording channels, taking into account the fact that there are two YCL recording channels per UZCI input.

In the JDZ, telephone and telegraph information is converted at the logical and electrical levels to a digital form suitable for further processing, and is recorded in the YDZ memory card in the form of files. In this case, the following recording modes are provided in each of the channels: continuous, by a signal from an external device, and automatic, in which recording is performed only if there is a voice signal in the recording channel. The file is either automatically generated at the end of telephone and telegraph information, or as a result of a control signal set on the touch interface 7.

Data on the size, file name, recording time and location in the memory card of the microcomputer 13 via a common bus 6, the Ethernet switch 5 transmits to the computing module of the control unit 4, with subsequent display on the display 8.

If necessary, any file can be listened to through the built-in speaker 9, and also rewritten to an external drive in the form of a memory card connected to the input of the YCL on whose memory card the file is recorded. The file recorded in the JAM can be deleted from the JAM memory card by control signals from the touch interface 7.

The size of the array of telephone and telegraph information recorded in the JDZ file is limited by the physical volume of the YDZ memory card.

When the power source 11 is turned off, the microcomputer 13 automatically connects the backup power source 12 and puts the UCD into autonomous operation mode.

In the event of a malfunction of the NCL, it changes without disturbing the operation of the other NCLs due to the network architecture of the construction.

Thus, the claimed UZCI provides an increase in the reliability and quality of the recorded information, as well as an increase in the reliability of the UZCI during its autonomous operation, through the use of a network architecture of construction, which indicates the achievement of a technical problem.
