The output of the CAB provides a voltage adjustment, a fractional convertible value. In the CISS of the same type of analog-digital blocks, 50 KOV (CAB) 3 have information input and output. The ADC is designed to convert electrical voltage applied to the input , in a digital code, information about which in the form of increments (output is given on 55. The memory block (BI) 4 has a number of information inputs, and they allow them to simultaneously record a number of numbers, and one output that serves to output one of numbers written in BP.60 Commute s block (KB) 5 has a plurality of data inputs and outputs and control inputs :. KB is a spatial switch. each output of the CB is connected to only one of the 65 information inputs of the TsRB, or TsAB, or BP, each information input of the CB is connected to the information output of the TsRB ILE CB. The control inputs of the KB are used to send commands and signals necessary for building specified connections of information inputs with information outputs. The input switchboard (KVV) 6 has two input inputs, a set of information outlets, and a control input. KVV b yrednazaignn for connecting one of the informational inputs to one of the information outputs on the control signals to the control input. Each IE1formatics output KVV 6 is connected to one single informational input of one of the CRH OR or one input of one of the CAB, and is intended for entering the initial data.

(the outputs of the block 11 are connected to the outputs of the block 8 settings). The input unit (BVV) 12 pr-ednaznachen for input of initial data and setup information in blocks of TsRB and TsAB and the program of coimmutation in the switch setting unit. BVV 12 "has information inputs and an output connected to the inputs of block 8 of the configuration of switches and switches.

The control panel (PU) 15 is intended for manual control of the work of the CISS and visual monitoring of the state of the CIS and its individual nodes; . and exit.

The control unit C) of the control unit 16 is designed to coordinate and control the operation of individual devices and the entire CIS, as a whole, for which the control unit has two-way control communications with the ACB, the communications block, the ACB and the control panel and the control input. CDH and switch configuration blocks.

Such a CISS has a wider area of application compared with: from the domestic devices, since it can directly connect a digital computer and an analog device; for example, an AVM, through its communication unit, central anti-clock room and ACB. In addition, the CISS allows direct intervention in its work by the human operator through the PU. For the CISS, the simplicity of the exchange of information between the blocks included in its composition is also characteristic, which is ensured by the availability of space-time switches of input 6 and output 7, controlled by a common setting for all switches by block 8.

Essential in the proposed CISS is that digital-analog and analog-digital blocks can be considered as a kind of decisive blocks, since the INPUTS are first, connected to the output of the switch, information is presented in increments of functions, and the outputs of the second, connected to the inputs KB, information is given in the form of function increments as well. as is the case for the inputs and outputs of CRH. At the same time, any CAB 2 can be connected to the output of any CDH 1, and also any ACB 3 can be connected to the inputs of any CDB 1.

The proposed CISS is designed to solve quite complex tasks with digital computers, AVMs and analog equipment. The task being completed is split into parts. That part of the task, which describes very fast-running operations and which operates, for example, with some external actions that cannot be described (wind speed, ambient temperature, pressure, etc.), can be assigned to the analog part. The part of the task, which causes relatively slow processes and requires a higher accuracy of solution than the analog part, is realized with the help of blocks of CRH and can be assigned to the digital part. The logical part of the task, connected with the processing of the results of the calculations, the acceptance of the corresponding commands for further: reproducing and changing the task, is assigned to the digital computer. The digital and analog parts of a task can also be considered as a structural subroutine of a digital computer, the use of which can be

carried out simultaneously with the solution of other tasks assigned to the digital computer.

The CISS can operate in the following modes: input of initial data, decision and output of results.

The initial data for the CISS are: program and numerical information. Software information 1B, in turn, is divided into a switching program that specifies the connection scheme between the CDH, CDB, and ACB units among themselves, and the tuning information that specifies the operation modes of the CDR (integration, summation, and logical operations). The switching program consists of lists of connections of the outputs of the TsRB and ATSB blocks with given sets of inputs of the TsRB and TsAB blocks. The setup information consists of the operation codes of all the blocks involved in solving the problem.

The numerical information includes the initial values of the integrands for the blocks in the digital integrator mode of operation.

The control data also includes control information: decision interval and print information interval, specified as a number of integration steps, decision accuracy as a code of the corresponding number of bits, as well as start and stop signals.

Input of the initial data can be made from three sources: БВВ 12, communication unit 13 with a digital computer and control panel 15. Input from the control panel 15 is made through the base unit 12.

Under the output of the results, the output of numerical information from the CRH and APPZ blocks is understood.

Works CIS as follows.

Input of the initial data of the products from BVB 12 (communication unit 13 and PU 15).

Before entering the configuration information, a corresponding input of the configuration information is received in the BUS, and in the switch configuration unit 8 the operational part of the command is recorded, which is stored in register 10. In this case, the operational part of the command means "Enter via KVV. The potential for the input of the tuning information is supplied to the blocks of the central hospital 1 and the central bank station 2 of 16.

After that, the number of the first of the blocks involved in the task is entered, which, however, the signal from the CU 16 is transmitted to the switch setting unit and stored in the counter 9. As a result, a command is written to the register 10 and the counter 9, meaning input via CWB 6 to the block with the number after decrypting this command in the AND decrypting commands command, the output of the switch setting unit 8 is given a control signal, through which the input KVV 6. connected to the output BVV 12 is connected to the output KWV 6 connected to the unit, having omer recorded in the counter 9. Then, the appropriate code is input Settings: th | 41noy information that the signal from the ECU 16 is input KVvb and passes at its output connected to the input of CRH. From the output of Q.V. 6, the first code of the LETTER INFORMATION is allocated to the corresponding block of the CRH. Thus, one block is tuned. If all subsequent codes need to be entered into blocks with consecutively increasing units by one, the block numbers are not entered, and before entering each next code of the training information from the BVV (communication unit) a pulse is emitted, counted by the counter 9. After each code change in counter 9, the output of the KVB 6 is also changed, which is connected to the input of the KVVb. If the next code of the configuration information is to be entered into the central hospital with a number different by more than one in relation to the number in the counter 9, then the block number corresponding to the input of the next code of the configuration information is entered.

After this, numerical information is entered into the given blocks of the central hospital and central hospital. Prior to this, the corresponding signal for inputting numerical information is supplied to the control unit 16 from the BWB 12 (communication unit 13 and the control unit 15), and an operation code, meaning "Entering numerical information." At BUST with 3TOiM, the corresponding control signals are received by writing numerical information to BVV 12, CRH 1 and CAB 2. The subsequent work sequence of the text is the same as when entering the configuration information. The only difference is that tuning information is not entered into the CAB blocks.

The switching program input is made as follows.

From BVV 12 (communication unit 13 c PU 15) through BWB 12 to block 8 settings of switches op: Efficiency, per part of the configuration command KB 5, which is stored in register 10. The operation code of the configuration command KB 5 can have two values: connecting paths in KB and disassembly of connecting paths of entrance of KB with a set of exits of KB. The counter 9 block numbers from BVB 12 (communication unit 13 and PU through BWB 12) records the address part of the command. At the same time, first comes the number of the CSR or ACB block, the output of which should be connected (disconnected when disassembling) with a set of inputs of the CRH or CAB and BP units. After deciphering the command in block 11 and sending the control signal from BU16 to block 11, the control inputs of CB 5 from block 8 are given a signal that determines which KB input (output of the CRP or ACB) is connected (disconnected). Next, from BVV 12 (communication unit 13 or PU 15 through | BVV 12), a sequence of numbers of inputs of the central district hospital or central location station comes. Each successive number either goes to counter 9, if it differs by more than one in relation to the previous value, or it does not.

but instead, the contents of counter 9 are incremented by one. Each time the command placed in the counter 9 and the register 10 is decoded by block 11, and by a signal; block 8 from the BUS generates the corresponding control signals in KB 5, determining which output of KB5 (input of the CRB, DSC or PSU) needs to be connected ( disconnect) with the previously installed KB 5 input (output of the central hospital

or ACB). Thus, all other connections of the inputs of the CB (outputs of the CRH and the ACB) with the outputs of the CB (of the entrances of the CRH. CAB and BP) are built (disassembled).

After setting the KB, the control information is entered into the control unit (codes defining the time of the decision and printing the information), and the CISS is ready for the decision. From BVV | 12 (communication unit 13 and PU15), a start signal is given to the WRCU, and resolution begins. Information from

the outputs of the central hospital and the ACB via the KB5 (information in the form of voltages) are output to the digital circuitry outputs, which can be connected to the inputs of analog devices. At the inputs of the ACB when connecting them to the analog outputs

devices are given information in the form of voltages. Under the influence of control signals from the BUS, into the CRH, the CAB and the ACB, in accordance with the operation codes of the CRH, in all blocks of the CRH, the CAB and

The ATSB processes the input information according to the algorithms of either integrating, or summing, or performing some logical operations, or, finally, analog-digital and digital-analog

transform.

In accordance with a given output interval, the recording signals from the control unit and power supply unit are supplied in such a way that information related to a given output point is stored in the power supply unit. From BP

the information is selected in the output unit 14, where it is either printed or transmitted to the indication in the PU15, if there is a need for this. In this way, results are output from a plurality of blocks at a predetermined time interval without stopping the decision.

Output of the results can also be carried out by signals from either PU15 or from communication unit 13. For example, if you need to follow a change in some timeless, then from the control panel, just enter the appropriate output command in switch configuration block 8. This command from the tuner to the control input KVYV 7 sends a signal to connect the corresponding input KVYV 7 (the output of the CRH and the ADB) to the output. The information from the output of the corresponding CRH and the ACB through QB 7 is passed to the BWB 14 and the communication unit 13. If necessary, output the results from

A greater number of blocks are given a number of corresponding commands to the switch configuration block 8.

In the case of joint operation with a digital computer, the communication unit 13 outputs to the input connected to

Digital computers as signals about the status of the CIS (input,
