The technical field

The invention relates to the field of electronic technology, combines the functions of computer technology, in terms of information processing of the data stream, and to a method of identifying the primary data. The product is a universal device, oriented and adapted for creation of automatic control systems of technological processes. The product does not belong to the field of computer technology, as does not perform computational procedures and has in its composition elements for their implementation and synchronization. At the same time, the product uses the functionality of processor systems, in terms of organization of associative information retrieval and build unaddressed memory space of concurrent access.

Prior art

In terms of build unaddressed memory, which is based on the structure of product no information available.

Solutions in terms of associative information retrieval computer systems controlled by data flow, known for a long time and the closest (in function identification) is a well-known system EP 0295876 A2 from 21.12.1988 based on associative memory, allowing almost instantly to identify the data by comparing them with stored data in the memory based on one or more databases.

This system comprises at least two switches, one of which provides the transfer of data from the modules of associative memory actuators, the other switch of the actuating devices in the modules of associative memory (see Optical associative memory for high performance digital computers with nontraditional architectures, V.S.Burtsev and V.B.Fyodorov, Optical Computing and Processing, 1991, volume 1, number 4, pages 275-288). The system includes centralized management and synchronization of processes of identification and issuing control codes.

The use of multiple modules associative memory allows you to increase the speed of search, as the search in the different modules of associative memory is carried out simultaneously. The disadvantage of a computer system and implemented it method is the relatively high power consumption and system complexity, the need for associative large amounts of memory to store intermediate results of calculations and operational unreliability, and poor protection from the negative influence of external conditions. To ensure the health of this product requires special measures for the establishment of certain "comfort" operating conditions: climate control, a fixed grounding, shielding, power supply, etc.

Rassmatrivaemaya allows you to maintain the functionality of processor systems (including the above) and to correct deficiencies in management systems in terms of survivability, reliability and trust.

The product is a universal product for systems involving the identification testimony of the external parameters of the controlled object with the simultaneous (and instant) development of project management solutions without the use of hardware-CPU, which provides for automatic start/stop actuators (without the use of computers) when it reaches the boundary, the controlled values (or range of values) of the external parameters.

The product can effectively solve the tasks associated with building an automated security systems and locks technological processes and equipment, to solve problems of control and identity management systems in the absence of maintenance and the possibility of creating "comfortable" operating conditions. Allows you to create a passive system with a high degree of protection from outside interference (climate impact, extremist, and hacker attacks) with minimal energy consumption with guaranteed implementation of all design decisions.

The technical result for ensuring high levels of survivability products and, accordingly, control systems, improved reliability, trust and reliability, the invulnerability of the external intervention as on objective, and subjective factors, including climate and hacker attacks, easing system design, production and maintenance is achieved by the following:

- the product is completely passive, asynchronous control system and does not contain device synchronization and clocking internal processes;

- the product is completely independent of the software and computing processes and does not contain them;

- product adapted for use in a computing environment, able to receive and send digital codes processor for further processing;

- the product is only intended to identify the occurrence of certain events and production management code, in accordance with the project management solutions;

- the product does not store, in explicit form, information about where and on what block (sector) of the comparison is that information and thereby protect the information from unauthorized access.

These solutions are achieved by the fact that the product: "Associative identifier of events (process)" represents the device architecture and circuit solutions implement the following properties:

the architecture enables the creation of unaddressed memory space, provides simultaneous access by entering the information to all project management solutions without the use of switching means, multiplexing and synchronization;

- circuit solution provides associative compare incoming information with stored design decisions on the fact of absolute convergence (physical matches the source with the stored information) and in fact "shadow" (logic) comparisons when significant evidence of primary sensors veiled General array of incoming information.

Associative identifier of the event process includes the following electronic and architectural components:

multi-layer (i layer) architecture products, organizing unaddressed memory space and providing equal and asynchronous access input information to each layer with respect to incoming data;

all layers products implement a single circuit and design the solution and are interconnected memory cells with elements of comparison data and control procedures records;

each layer of the product contains the following electronic components:

the protection circuit from the load associated with receiving input data;

the memory block storing the primary (design) data of N-bit input data register (N - integer);

the physical schema comparison, performing a bitwise comparison of known input data associated with the components the memory input data containing electronic valve, open access articles to the data in case of physical data;

the logic of the comparison, performing a bitwise comparison of known input data associated with a memory block of the input data and containing an electronic valve that opens access products to the data in register logical data;

the comparison circuit to "0" input is used to control the correct procedures for recording new data;

the schema permissions and write locks that ensure the correctness of the recording of new data-free data sector with electronic gate, blocking the entry of the zero data and the data previously written,

provided positive identification input device generates the output data of direct control and diagnostics monitored process.

This protection circuit loads is made in the form of a Schmitt trigger and a diode assemblies, and electrical characteristics of bit-register data signals sufficient to open the electronic valves (thyristors) to activate the power of automation and processing computing systems.

In this paper the concepts of physical and logical comparison mean:

- the result of a logical comparison of verbatime is provided by the coincidence of significant digits (LOGICAL "1"), stored in memory products, with the corresponding bits of the data of external information, regardless of status and values of the other bits of the incoming data, i.e. the input information contains bits corresponding to logical "1", and the stored information. In this case, the product produces a signal (and thus control code) logical match regardless of the values of the other bits of the input information;

signals physical comparisons are produced when the physical condition and the absolute coincidence of the values of signals input from external sensors, the combination of which represents the combination of previously stored project information.

The device illustrated by the following drawings.

- Figure 1 - structural diagram of the Associative Identifier of Events (Process) (AIS(T)), with "I" units of comparison (Fig. marked layers).

- 2 - General scheme of execution of one of the layers (Comparer) Associative Identifier of Events (Process).

- Figure 3 is an example of the use of the product in automatic control systems.

Block diagram of the construction of associative identifier of events (process), shown in figure 1, is a "silo" organization with the presence of the first layer (where i is an integer). Each layer represents a block is annenia and the control unit records the new data, block diagram is presented in figure 2. All layers products have the same circuit and design solutions and contain the following nodes.

1. The control unit records (figure 2 - scheme of permissions and write locks), which determines the state of the block comparison (free/busy), produces a signal that new data is written simultaneously to all the registers of the free sector (as, in fact, the product is a conventional device). The unit is built on the principle of using a single-bit memory cells, performing the role of "checkbox". Open "the box" refers to a sector free to write. After the procedure, write the check box closes and moves to the open state of the check box next sector.

2. Memory block input that is designed to store important and expected combinations of signals on the input information. The expected values are determined by the design decisions.

3. The physical schema comparison, bitwise comparison of project data input. A positive result of the comparison - output enabling signal reset data register f to the corresponding common bus f and issuing a signal to the lock signal "write". This lock eliminates the possibility of additional, new data, if any, have already been saved previously.

4. Logic compared the I - a bitwise comparison of project data input. A positive result of the comparison - output enabling signal reset data register L to the corresponding common bus L.

5. Comparison circuit to "0" input. A positive result of the comparison, the lock signal "write"lock physical and logical schemas comparison performed by the logical element &(And). This scheme prohibits all operations, if the input information is not meaningful.

6. K - bit physical register data custodian alternative information, relevant project management solutions.

7. J - bit register logical data custodian alternative information, relevant project management solutions.

The memory registers is performed on cells with functions corresponding to the function's trigger. The nonvolatile memory cells is achieved through the use of technology from "burn bridges" to use FROM.

Each sector (layer) articles re lished the same functions, at the same time has access to external information, stores it, analyzes (compares) in asynchronous mode and perform the following procedures:

- storage known (design) data for subsequent comparison;

- storing control codes corresponding design decisions;

- selection of external mass flow input data identified as corresponding to known (design) data;

- output the resulting signal matching/identify external and stored data and output on a common bus alternative codes;

- signal processing for write access new/primary data on specific Comparer free to write.

External data stream is perceived AIS(T) (and each block (sector) comparisons, respectively) as a bitwise information in a parallel digital code corresponding to a logical "0" or logical "1".

The resulting signal identification can be either a single signal of the comparison result, and control signals that must be generated and transmitted in at least one execution unit.

The product of the AIS(T) represents the conventional associative memory device in which the recording of the primary data is not managed by PR is the narc first free sector - block (sector) comparison completed and the unit of comparison is opened for writing. The preparation of each sector to capture and lock entries are made automatically according to the principle of running lines without using a processor and software resources and are controlled by the control unit records in each block comparison separately.

New input identification data can be written only in a free block comparison (if any) directly by the operator to control the process, and by means of computer systems.

The management team "account" for the product is only one team - record new input data, all other comparisons, the signal processing result identification, etc. are performed automatically in asynchronous mode, without any external control and synchronization.

To exclude the possibility of external interference in the work product all circuit blocks (sectors) of the comparison performed in such a way that does not allow operations with modification, correction and deletion of recorded data. Adjusting the stored known data to identify possible only with the complete destruction of all data in product and form a new block identification information for the entire device or Phi the systematic destruction of the device.

Novelty consumer qualities

In some electronic devices, capable of handling input signals for control of technological process and production control actions, the product of the AIS(T) is premiato the Noe between the relay logic circuits and systems, based on the programmatically-processor data processing. The product combines all the positive characteristics of the relay equipment (reliability, simplicity to operating conditions and maintenance, high performance, autonomy and so on) and the functionality of the processing system in terms of parameters, identification of primary data, identify and generate control signals. A distinctive feature of the AIS(T) is its versatility and have a minimum of electrical connections and radio, which makes the device highly reliable, robust and commercially made.

In addition, the system built on this item, do not require the implementation of new developments and accordingly undergo additional testing, certification and so on, reduce the period of commissioning works on objects implementing the system, increase the serviceability and operating life of the product. All this significantly reduces the cost of the whole system.

The main difference between the proposed product over similar products in the country and abroad is that the variety of combinations of input signals are not processed, analyzed for possible overlaps, drifts, etc. in Addition, the product mimics the design decisions neither technical nor at the software level is, and accepts them as fact, previously installed. And on each the occurrence of a specific event, there are certain solutions that are also defined in advance.

Product simultaneously identifies all significant and previously recorded information in the mass flow of external incoming data, regardless of their size, does not require pre-processor processing each incoming signal and its analysis on interaction and based on related data.

The product is provided for use in systems where the output of the external control signals of a certain technological object is rigidly connected with a specific set of and sequence of generation of control signals, and in systems where it is important to highlight from uncertain and mass flow of information component, previously defined as the standard.

An example of the construction of the system identification data

Process control involves two management options: management in the normal course of the process and management/decision making under abnormal operating conditions. Normal operation condition uniquely determines the compliance values of the primary sensors process control algorithm and decision management. Violation of the process involves the t hide patterns testimony primary sensors with control mechanisms. In this case, provides a mechanism for identifying significant "shadow" of the control signals on the General background of uncertainty in the sensor data.

Consider a simple example of the automated liquid filling some capacity with the use of the product AIS(T).

In this case, are controlled by the following parameters:

- high liquid level in the vessel;

low fluid level in the tank;

- alarm low liquid level;

- feed pump is enabled (controlled by either the pressure or voltage);

- feed pump is turned off.

To manage this process requires only two commands:

- enable feed pump;

turn off feed pump.

To diagnose denote the parameters that must be made regardless of the technological process:

- failure of level sensors;

- emergency situation: low liquid level and the pump is turned off.

Set the control parameters in tabular form.

Unit 1 determines controlled primary readings of sensors designed for normal process control and system diagnostics. In our example, to the normal control include the following statement:

- high level in the tank and pump included.

- low level in the tank and the pump is turned off.

These options require decisions that are reflected in unit 2. In the first case, turn off the pump, the second to include.

However, even with failure of one of the sensors, accidental or natural, the whole chronology of the events management process can be broken. To prevent effects of this factor in the product is provided by tracking the background/shadow events. This function is implemented in the design of the product and is executed in parallel with a given program management product (logical line).

Logical match involves the identification of significant or critical parameters (or set of parameters), which determines the deviation of the technological process, regardless of the General indications of the primary sensors. The task of the critical combinations of input signals is performed when the primary data input and to the forms of control are reflected in columns 6, 7 block 1 in this example). Column 6 specifies the diagnostic operation, column 7 - emergency. Decisions on these readings is determined by the values set in the logical register (block 3), which may be transmitted to the operator console or in the system computer diagnostics, or to the input of similar articles AIS(T) for automatic processing.

According to this scheme implemented all systems of governance, from the relay circuits to processor systems. The proposed option reduces the cost of the system increases reliability, reduces dependence on energy and maintenance costs of the system.
