Description

The invention relates to storage devices. Known associative memory device for the main author. Ev No. 640368, containing a drive connected to a writing driver and a number receiving and issuing unit, a counter connected to the register and writing unit, a data format setting unit, a service signal generation unit and a control unit connected to the number receiving unit and the counter, with the inputs of the backward block of the NIN data format connected to the outputs of the register, and the outputs respectively to the inputs of the accumulator and the signal generation unit, the outputs of which are connected to the inputs of the number output unit 1. In this device information e arrays with current data (n an example, the coordinates of the object trajectory measurements of time fixation of these coordinates, service combinations of - marker, by control, etc...) through the output unit number is provided to the consumer. The drawback of the device is the need to take into account when processing on a computer slowly changing parameters (meteorological conditions in the location of the measuring means, type and characteristics of the object, frequencies, etc.), which allows to increase the accuracy of the results of information processing on the computer (during secondary and tertiary processing ). The numerical values of these parameters could be included in the format of the data transmitted. However, this would lead to a significant increase in the time of data output and reduce the reliability of the device. The purpose of the invention is to increase the reliability of the device. The goal is achieved by introducing an additional drive and a messenger control unit, the input of which is connected to one of the outputs of the number receiving unit, the first output is connected to one of the inputs of the register g and the second output is connected to the inputs of the service signal generation unit and the first input of the additional accumulator , the second input of which is connected to the outputs of the data format setting unit, and the outputs of the additional storage device are connected to one of the inputs of the number output unit.

The drawing shows a block diagram of the proposed device.

The device contains a drive 1, a block 2 for receiving numbers, a register 3, a counter 4, a block 5 for issuing numbers, drivers for writing 6, a block 7 for generating service signals, a block 8 for setting the data format, a control for block 9, a block 10 for local control and an additional drive 11,

Block 10 provides one-time or multiple transfer of slowly varying parameters at any time outside the measurement session.

MokeT unit 10 to be implemented as logic circuits that generate data read enable signals from accumulator 1 and service signal generation unit 7 and data read inhibit signals from storage unit 11 during a measurement session, and read inhibit signals from storage unit 1 and read permission signals from unit 7 generating service signals 7 and accumulator 11 — outside the measurement session.

Drive 11 provides for the input and storage of data on slowly varying parameters (meteorological conditions, type and characteristics of tracking area, frequencies, etc.).

The drive 11 can be implemented as a set of multi-position switches (four-switch switches with 10 positions), providing input, storage and conversion of source data from decimal to binary code. .

The input of block 10 is connected to one of the outputs of block 2, the first output of block 10 is connected to one of the inputs of register 3, the second output is connected to the inputs of block 7 and the first input of accumulator 11, the second input of which is connected to the outputs of b-lok 8, and the outputs of accumulator 11 are connected to one of the inputs of block 5.

The device works as follows.

In addition to the information signals, the signals that characterize the mode of the associated devices, including the signal of the measurement session (the Work signal, are received, are received at the VHBD of the number receiving unit 2).

Signal Operation from the output of the number receiving unit 5 is fed to the input of the control unit 10, which generates an information read resolution signal from the accumulator 1 and the service signal generation unit 7 and a read inhibit signal from the storage unit 11. Information from the source is supplied to the number receiving unit 2 and stored in it during the time of the analysis of its reliability by the unit

Control 9. In the case of reliable information, it is entered into drive 1 by means of counter 4 and the drivers 6.

The reading of information from accumulator 1 is performed using

register 3. The read out of accumulator 1 and block 7 for generating service signals information through the block 5 of issuing numbers comes to the consumer.

Q In the absence of a signal, the control unit 10 generates a signal prohibiting the reading of information from accumulator 1, and the signal, I authorize: - the readout of information from the receiver 11 and the signal generation unit 7. In addition, in the control unit 10, signals are generated that provide a single or multiple start-up register 3 in the absence of a signal.

0, the register 3 reads information from the accumulator 11, the signal generation unit 7 via the data format setting unit 8. Read from these blocks of information

5 through the block 5 issuing numbers comes to the consumer.

The advantages of the described device in comparison with the prototype are that the accuracy of the processing of the data of trajectory measurements on a computer is improved by taking into account the slowly changing parameters when processing the data. In addition, the delivery and input to the computer of the slowly changing parameters do not require a significant increase in the transfer time and change the input and unpacking programs.
