ki data.

The device contains an asynchronous communication adapter 1, a block of 2 keys, a block of 3 buffer registers, an indicator board 4, blocks 5 and 6 of memory, a driver 7, a generator of 8 clock pulses, a data installation block 9, a switch 10, a data bus 11, a bus 12 addresses, output 13, inputs 14-16,

The data installation block 9 contains a comparison block 17, a reversible counter 18, a switch 19, an AND 20 element, triggers 21 and 22, an OR-NOT 23 element, inputs 24-29, and outputs 30 ..

The device works as follows.

After the number of objects to be polled is set in binary code, for example, using a plug or toggle switches or a switch, the supply voltage AND is turned on: the memory elements are automatically set to the initial state,

The generator 8 continuously generates pulses with a frequency of about 1 MHz, which are converted into two time-non-intersecting clock sequences for the operation of the command generator 7. The shaper 7 generates address signals (in a parallel code) via the address bus (ША) 12 through the bus drivers-amplifiers, 11 data signals (in a parallel code) and control signals for recording data (in a parallel code) and information signals (write) "-.And reading commands

According to SM 11, the imaging unit 7 transmits to the asynchronous communication adapter 1 a parallel code r of the next number of the object being polled, which is recorded in the transmitter of adapter 1 and stored there until the next code arrives.

The control object, the number (address) of which coincided with the number (address) encoded in the code sequence, forms in response a signal in the form of a sequential code of pulses, carrying information about the state of the object.

This response serial code is received from the object via another two-wire line of communication to the receiver of communication adapter 1, where the serial code is converted into a parallel one.

The shaper 7 reads from the adapter 1 information about the state of the object according to step 11 using read signals and the address code of the adapter 1,

The read (received) information about the state of the object, the shaper 7, is then transmitted via SM 11 to memory block 6.

Reception of information about the state of objects by the adapter 1 connection and its recording in block 6 is carried out using signals

35, the requirements for recording and reading information placed periodically by the transmitter and receiver of the communication adapter 1 at SM 11 and read by shaper 7 using read signals

40 and address code.

The number of objects (N) connected to the device for collecting and displaying information that was set in advance when the equipment is deployed,

45 is recognized by shaper 7 of SM 11 via switch 10 by the coincidence of the read signals and the address code.

5Q Thus, the switch 10 allows to reduce the time of receiving (input) information, and therefore reduce the time for processing it, in order to display it on the scoreboard 4, and this saves 55 the efficiency and versatility of the device when used in various systems.

After the end of one cycle of interrogation of objects (up to the established value, the code is written to the adapter 1 when the write signals and the address code on the UA 12 coincide.

During the time interval between two successive moments of writing the codes in adapter 1, the parallel code is converted into a serial code and outputted through a linear amplifier via a wired communication line into objects.

The control object, the number (address) of which coincided with the number (address) encoded in the code sequence, forms in response a signal in the form of a sequential code of pulses, carrying information about the state of the object.

This response serial code is received from the object via another two-wire communication line to the receiver of communication adapter 1, where the serial code is converted into a parallel one.

The shaper 7 reads from the adapter 1 information about the state of the object according to SM 11 using read signals and the address code of the adapter 1,

The shaper 7 then reads (received) information about the state of the object and then sends step 11 to memory block 6 via SM 11.

Reception of information about the state of objects by the adapter 1 connection and its recording in block 6 is carried out using signals

requirements for writing and reading information, periodically set by the transmitter and receiver of the communication adapter 1 at step 11 and read by driver 7 using read signals

and address code.

The number of objects (N) connected to the device for collecting and displaying information that was set in advance when the equipment is deployed,

is recognized by shaper 7 according to step 11 via switch 10 by coincidence of read signals and address code.

Thus, the switch 10 allows to reduce the time of reception (input) of information, and therefore reduce the time for its processing, to display on the board 4, Ply this saves the efficiency and versatility of the device when it is used in various systems.

After the end of one cycle of polling objects (up to the set value N) and recording information in block 6, the imaging unit 7 issues commands to block 6 to read information about alarm conditions (if they were recorded during cyclic polling of objects) and write it to board 4 through block 3 buffer registers.

Writing information to block 6 occurs when the code simultaneously coincides (according to Sha 12) on the inputs of RAM 6 and the write signals.

The reading of information from block 6 occurs when the address code (according to ША 12) coincides at the inputs of block 6, the reading signals. The read and write signals are mutually exclusive at the same time.

The information is written to the buffer registers (address codes and information for the board 4) in two steps. First, from the generator 7 to the block 3 of the buffer registers is issued by SM 11 the board address code 4, which is written to one 8-bit register when the write signals and The address code is from SHA 12. Then, the shaper likewise writes the information code for the board 4 into another 8-bit buffer register.

After that, the display 4 generates a write signal simultaneously with the address code (for example, A15). coming in on the AC in block -3 of the buffer registers. The entry in the block 3 of the buffer registers of information about the emergency conditions of the objects, the shaper 7, produces priority in relation to other information from the objects: and in sequential numbering, different from the numbering (ordering) of the address of the objects themselves, but the object number (address) is stored.

Before writing to the buffer registers, the driver 7 polls at SM 11 first the key block 2, and then, if required, the data set block 9,

From block 2, the keys are queried.

signal blocking using read signals and address code7

If this blocking signal is not present, the driver 7 will continue to issue control commands in order to display information about the emergency situations of objects.

If the blocking signal has- .. s or there is no information-about the emergency conditions of the objects, he interrogates the data setting unit 9 by simultaneously matching the read signals and the address code.

From the output of block 9 through SM 11, the shaper 7 receives the binary code of the address of page 1 of memory for board 4. This number of pages (N) is related to the number of polled objects (N) by

where K is the number of layers of information simultaneously displayed on the board 4.

Since N can be changed and determined when the hardware is deployed, the number n is a value dependent on N. It is set at the inputs 15 of the device (for the maximal value) when the hardware is deployed.

Shaper 7. After polling the code of the page number of the memory converts. this number is a binary number that is a multiple of K, in order to read information from block 6 in accordance with the selected page.

In addition to iToro, Shaper 7 Converts a binary code into a binary-decimal and reads for each familiarity code of the corresponding character (i.e. a digit or a letter) for display on the scoreboard 4.

The data setting unit 9 allows, firstly, promptly changing information, i.e. view information about all the polled objects sequentially or selectively (20 teams each) do not disperse the operator’s attention and facilitate reading the commands in large portions (pages), at the same time, reduces the time for retrieving and processing information, because it scans for displaying the scoreboard and only that part of the information about the state of the objects that the operator currently needs is converted,

The two keys + and -, which are f in the 2 key block, allow the operator to search pages faster (right and left), which improves the operation of the device. So, for example, when you press the key

f the signal formed in block 2 of the keys is fed to the S-code of the trigger 21 and to one of the inputs of the element OR-23 23 of the unit 9, the RS flip-flop is switched and a high level is formed at the first input (mode 5) of the reversing counter 18 voltage (logical unit). At the first entrance. The reversing counter 18 is set by TaKiiM in the manner of complexing and (summing pulses).

At the informational (D) input of the trigger 22, through the element 23, a logical zero signal (low voltage level) is generated.

When the next pulse (positive edge) arrives from the output of the generator 8 to the input 26, and hence to the synchronizing input of the trigger 22, the latter switches to its output.

The course associated with the clock input of the revolving counter 18 changes the voltage level from high to low. In this case, the reversible counter 18 of the state will not be changed.

When the + key is released from the block 2 key output to the input 24 of block 9, the high level signal is stopped. When H.TOM triggers the inputs of the first and second memory blocks and the asynchronous communication adapter, the key block whose first outputs are connected to the data bus, the input-outputs of the asynchronous communication adapter and the first memory block are connected to the data bus, the output of the second memory block ti connected data, block buffer registers, indicator, that was,.

25 that, in order to improve the speed of the device, a command driver, a clock generator, a data setting unit and a switch, and the first fore outputs are entered into it. „, The YP command of the world connected to the bus

Ger 21 does not change its state, Ju,. .

and on the informational (D) input of the trigger 22, the logical unit level appears through the element OR-NOT 23. Upon receipt of the next im. the pulse to the input 26, and thus to the synchronization input of the trigger 22, the latter switches to the state of a logical one. In this case, the reversible counter 18 changes its state by plus one.

The binary status code HOBot o is supplied from the outputs of the reversible counter 18 simultaneously to the inputs of the comparison unit 17 and to the inputs of the switch 19.

When the status code received at the first inputs of comparison unit 17 coincides with the code number set at its second inputs, a signal is generated from its output at the third input (zeroing), under which the reversible counter 18 is zeroed. Thus, the loop and sampling time is reduced. Similarly, the operation of the data setting block 9 occurs when the operator-key presses - are pressed.
