The main disadvantage of the prototype is the reduced operational reliability of the system, due to the lack of signals about the performance of each sensor of the system and the communication line among service personnel and information consumers. The purpose of the invention is to improve the reliability of the system during its operation. The system for collecting and processing information includes an electronic computer, a control unit, an addressing device containing detectors, sensor address registers,, a group of two-input elements, and an input unit for initiative signals, and also n devices. input information containing polling blocks, buffer registers, groups of three-input elements And and blocks for input of discrete information, m sensors, n elements .OR, whose inputs are associated with all the outputs of the group The input elements are And, and the outputs are connected to the control inputs of the two-input elements.

The drawing shows a block diagram of the system. The control unit 1 is connected to the corresponding outputs to the information input devices 2 and the addressing devices 3, the numbers of which are equal to the number of groups in which all the system's number-pulse sensors are combined. Usually one group corresponds to a large production unit, for example, a workshop, a section. The device 2 input information contains connected in series

| polling block 4, buffer register 5, group 6 of three-input elements And and block 7. of input of discrete information, Each device 3 addressing contains a serially connected detector 8, register 9 addresses of the sensor, group 10 of two-input elements And and block 1V for input of initiative signals, K The 1 group of three three-input elements AND is connected to an element 12 OR the output of which is connected to one of the inputs of group 10 two-input elements AND, Element 13 matches connected to the input of element 12 OR The outputs of blocks 11 of initiative signals 7 input discrete and formation and the inlet of each element matcher 13 are connected to respective computers tires 14,

The system works as follows.

Control unit 1 performs the following functions:

-generation at the first outputs of the packs of consecutive polling pulses, uniformly distributed in the pack over time; the duration between packs is equal to the duration of the pack itself, and the number of polls. pulses therein corresponds to the maximum number of message bits of each pulse number sensor;

-distribution of packets of interrogation pulses by groups of outputs, corresponding to the groups in which the number-pulse sensors are combined; the number of groups is equal to the number of objects on which sensors are installed (for example, an object can be a factory, a workshop, and t, n,) j distribution in time of packs of polling pulses in groups of consecutive (t, e, first a number of packs are fed sequentially to one of the outputs unit 1, and then successively to its other output and t, d) j number, packs on one output equal to the number of respondents of sensors in this group;

- generation of control single signals at the bottom according to the diagram of the signals arriving during each pause between the bursts of interrogation pulses corresponding to a given group of polled sensors, t, e, in sequential mode for all groups.

For each group of sensors in the information input device 2, the polling unit 4 performs the function of sequential switching of sensors to the input of the buffer register 5. As the polling unit 4, an annular distributor can be used, the control signals for which are polling impulses sent to its control input .

The discrete information input unit 7 is an intermediate device for interfacing input signals with computers and for inputting them into the computational device according to its commands.

In the addressing device 3, the detector 8 performs a function of detecting a packet of an oprospector arriving at its input and a single signal is formed with a duration equal to the duration / burst. An RC chain can be used as the simplest detector

1 The register of the sensor address 9 performs the functions of a ring binary counter with a counting input, the number of states of which is equal to the number of pulse sensors combined into this group. The input signal input unit 11 is an intermediate device for interfacing input signals with a computer and for inputting them into a calculating machine according to the instructions of the unit 11 itself,

The functions of the remaining blocks 6, 10, 12, 13 correspond to their names and do not require additional explanation,

In the initial position, the sensor address register 9 in the addressing device 3 is in the initial (zero) state,

At the time the system is put into operation, control unit 1 generates polling packs on its first stages

g pulses, first a number of packs on one output, then on another and t, d, Yelicheskie packs on each output is equal to the number of sensors belonging to this group, served by the corresponding devices 2 and 3,

The first packet arriving at the control input of the polling unit 4 first commits the first sensor of the first group to the communication line between the polling unit 4 and the buffer register 5. Each of the pulses in the burst is clockwise relative to the bits of the first sensor. Therefore, the information from its output is rewritten in a serial code over the communication line to the buffer register 5. At the same time, from this packet of interrogation pulses, the detector 8 generates at its output a single signal arriving at the input of the sensor address register 9 to transfer it to the first state at which All of its outputs form a combination of signals corresponding to the address of the first sensor. This combination (for example, 1 9 first-time when O is in the others), In a parallel code, enters the information inputs of group 10 of two-input elements I. After the end of the first batch of survey pulses from the lower right output unit 1, a single control signal is received on the direction inputs of the register 9 addresses of the sensor and a group of 6-input elements And, opening them. In this case, information from the buffer register 5 is read in the parallel code into the discrete information input block 7, and is also fed to the inputs of the element. 12 OR, simultaneously with reading. It is erased in register 5. If at least there is at least one unit 1 at the outputs of group 6 of the three-input AND elements (i.e., if there is information to be accumulated and processed in the computer as part of the message transmitted from the primary data element OR is triggered and the signal from its output goes to the control input of group 10 two-input elements I. In this case, the address of the first sensor is rewritten in parallel to the code in the input signal input unit 11. In the absence of 1 on all outputs of group 6 (which is corresponds to the lack of information on this sensor to be accumulated and processed) element 12 OR does not work and the sensor address is not received in block 11. From block 11, the initiative request signal is sent to the computer by having it on any of the sensors of block 11. This multi-bit the signal (sensor address) causes the memory field in the computer to be allocated for recording information at this address, and upon a command from the computer (after it is ready to receive) the information from the discrete signal input block 7 is copied to the computer, setting the blocks 7 and 11 at initial (zero) state. In case of failure of the element 12 OR, the unit 11 does not produce an initiative signal to the computer. The next packet of interrogation pulses, coming from the top output of block 1, produces the same ohpoc of all bits of the second sensor of the first group, recording the corresponding signals in the buffer register 5. Through the detector 8, a single pulse arriving at the input of register 9 of the sensor address sets it to the next position, In this case, the combination of signals on all of its outputs corresponds (in the received coding system) to the address of the second sensor. Further, all operations are repeated in the manner described above. At the end of the interrogation of the sensors of the first group, the corresponding register 9 of the address of the sensor returns to the initial state. : After interrogating the sensors of the first group, the next packet of interrogation pulses begins to flow to the next upper code of unit 1, performing similar operations with the following sensor group, etc. After alternate polling of all groups of sensors, unit 1 produces a new polling cycle, etc. during the entire non-period of control of the production process (shift, day, etc.). Such a construction of the information collection and processing system allows the computer to be freed from the forced polling of all sensors, and the subconnected computational machines and the input of information in it for accumulation and processing is performed only if the last one is available at the output of the next date. chica. :,.; ,, ... - .- ....,;.,,; .. Monitoring of the state of communication lines and the health of information sensors is carried out as follows. In a message transmitted from each monitored sensor, there is one (or several) bits in which the signal (1) is permanently recorded in the sensor itself. Output corresponding to his bit on the bu-. The ferric register 5 is connected via group 6 of three-input elements And to block 7 of the input of discrete information. But there is no connection between this output and element 12 OR. Upon a command from a computer 14 (periodically with the required frequency according to the program, or upon the initiative requirement of the system personnel), the signal from the output bus goes to one of the inputs of a group of elements 13. During the polling of each sensor, the polling pulses of each packet arrive at the input of a group of elements 13 And, and from its output, the input of element 12 OR, thereby causing compulsory polling of the states of all bits of the next sensor (rewritten into the buffer register 5) regardless of their state. The information supplied to the computer is analyzed for the presence of 1 in the check digit. In the absence of 1 in the test bit (link breakage, sensor failure, etc.), the staff receives a corresponding signal via a computer. For example, a computer program either prints out the fault information on the code device (terminal), or (and) changes its own program of further information processing, for example, excluding it from this sensor from the general information array. Thus, the operational reliability of the system is increased while retaining the remaining advantages of the prototype (a small number of communication lines, freeing up computer time, and the possibility of using it to solve other tasks in parallel). All units of the system are made on the known circuits of automation and electronics (counters, triggers, valves, RC-chains, shift registers). The a t system was prototyped on an elementary base (microcircuit) of an aggregate computing system (AGBT), in part of the M-6000, M-7000 complex, and also using entirely separate standard nodes (input modules) that make up this package. The input discrete information module (SCD) is a 16-bit register, the initiative signals input module (MVIS) is 8-bit. Therefore, in the system when prototyping, the sensors had a message length of no more than 15 bits (one bit - 16th was assigned to control the system) and united in groups of 256 pieces (2 is the number of IBIS states). I, From the total number of sensors and periodically polling each of them depends on the frequency of the polling pulses (in each pack), which, when testing the layout did not exceed 100 kHz.
