The disadvantage of this device is low efficiency, which is expressed in the loss of information about short-term changes in the state of controlled objects in case of changes. the states in the previous polling cycles are not fixed by the operator, as well as in the case of a continuous sequence of changes in the states of monitored objects, besides the device’s low functionality, which means that the device reliably fixes only two states of each of the monitored objects. The closest in technical essence to the present invention is a device for signaling the state of monitored objects, containing sensors of state of monitored objects whose outputs are connected via a switch to the first input of the comparison unit and to the first input of the first key, the second input of which is connected to the output of the unit comparison, output to the recording input of the first memory block, the output of which is connected to the second input of the comparison unit and to the first input of the second key, the second input of which is connected to the output of the inverter, and Exit to the signal input of the constant indication, a synchronization unit, a first output of which is connected to the address inputs of the switch, the first and second:

blocks of memory, blocks of constant and

short-term indication, the second output of the synchronization unit through the frequency divider and the first input of the third key is connected to the signal input of the constant indication unit, the output of the first key is connected to the write input of the second memory unit, the output of which is connected to the first input of the readout unit whose address input is connected to the output of the synchronization block, and the output to the sigpa: the 5 n inputs of the constant and short-term indication blocks, the control output of the short-term indication block is connected to the second-i input of the readout block, second th input of the third key and the input of the inverter.

The advantage of the known device is the possibility of storing information about several changes in the controlled objects L2J.

However, the known device has low efficiency. In the known device, it is not possible to fix an object with a maximum flow of state change, since the information for processing by the operator is received in accordance with the address generated by the synchronization unit at the time of extinguishing the processed information in the short display unit, i.e. . the choice of the object, the information about which is received for the processing of operators, is of a random nature. Since the changes in the states of the sensors are a random process, some objects may undergo multiple changes in their state, while others may be single or not change at all. Consequently, due to the randomness of the choice of an object, the operator will be given information on those objects that have undergone one-time changes in their processing.

states, while objects that have repeatedly undergone changes may further change their states, which will lead to the complete filling of the memory area allocated for this object, and the subsequent loss of information about the change in the state of the object.

Information loss can be avoided by decreasing the number of monitored objects or by increasing the amount of memory allocated to fill in information about changes in the state of monitored objects, but this will reduce the efficiency of the alarm device.

The purpose of the invention is to develop the information content of the device,

The goal is achieved by the fact that in a known device, containing a switch, the inputs of which are connected to the sensor outputs of monitored objects, the switch output is connected to the first inputs of the comparison unit and the key, the output of which is connected to the first inputs of the first and second memory blocks, output the first memory unit is connected to the second input of the comparison unit, the second one. the key input is connected to the output of the comparison unit, the first output of the synchronization unit is connected to the address input of the switch, to the second input of the first memory block, to the first input of the constant indication block, to the second input of the second memory block, short-term indication block, air force / unit determining the maximum and the meter block, the output of the second memory block is connected to the first input of the short-term indication block, the output of which is connected

FIG. 1 shows a block diagram of the proposed device; Fig. 2 shows an example of the repetition of a maximum determination unit. The device contains a group of sensors 1 state, synchronization unit 2, switch 3, comparison unit 4, first memory block 5, fixed indication unit 6, key 7, second memory block 8, counter block 9, briefly temporary display unit 10, block 11 determines no maximum. The maximum determination unit 11 contains counters 13, / decoders units, the first trigger 15, the first element H 16, the register 17, the first element OR 18, the second trigger 19, the second element I 20, the poll counter 21, the poll decoder 22, the third elements AND 2 second element SHS 24. Synchronization unit 2 performs sequential generation of address signals to the address inputs of switch 3, memory blocks 5 and 8, fixed indication unit 6, counter block 9 and high read and write signals C1 and C2 in the second memory block 8. The first block. 5 memory is intended for storing data on the nature of changes of each sensor 1. The second memory block 8, having N cells of L fields in each cell, is intended for storing data on the nature of changes in the states of each of the N sensors 1. In this case, sensor 1 may have n states. The continuous display unit 6 is intended to highlight the flowing states of objects. Block 9 of the counters is designed to count the number of changed states of the objects under control. Block 10 short-term display is designed to indicate the number and nature of the new state of the monitored object. The maxim pma determination unit 11 is designed to determine the monitored object with the maximum number of changing states. The maximum determination unit operates as follows. After the information from the output of the short display unit is received by the operator, it resets the cell of the memory block 8 and starts the block 11 for determining the maximum. At the same time, the counters 13 record the contents of the counters of block 9 and are performed at the second inputs of the set-up of the first trigger 15 and resetting the register 17 and the polling counter 21. Through the open element AND 16, the counter inputs 13 receive pulses T. Once a either from counters 3 it reaches full filling, at its outputs all units are in cc, which will be determined by decoder 14 and recorded in register 17. The suggested counter is a counter in which the maximum number of operations is recorded. The signal from the output of a given cell of the register 17 through the first element 18 of the first 18 resets the first trigger 15 and triggers the second trigger 19. The counting pulses are accessed by the open second element I 20 into the polling counter 21. T2. The polling decoder 22, which works in conjunction with the polling counter 21, generates alternate polling pulses of the third And 23 elements, the second inputs of which are supplied to the states of the corresponding register cells 17. If the register cell 17 is in state 1, then the output of the corresponding third element And 23 is a VITS signal, itoTOpbtti in the positional code represents the sensor number. With the maximum number of triggers, since the polling, the state of the register cells 17 starts with. Always, then even if there are several cells in the register, .HSYA P in the state memory unit 8 receives the signal TC to the sensor control with a minimum number. Thus, the proposed implementation of the aximum definition unit 11 detects the sensors with the highest number of alarms, and if there are several such sensors, select one of them with the smallest number. The alarm device works as follows. At the time of generation of the next address signal by the synchronization unit 2, the corresponding sensor 1 via the switch 3 is connected to the input of the comparison unit 4, to another input of which information about the output signal of this sensor received in the previous polling cycle is output from the corresponding cell of the memory unit 5. If the data entered on both inputs in comparison block 4 are the same, then there is no signal at the output of this block. At the same time, the data from memory block 5 is read into block 6 of constant brushing, where it is stored until the next interrogation of that zhadatchik. If the data entered in comparison unit 4 are different (the state of the monitored object connected to this sensor has changed), then at the output of comparison unit 4, a signal is generated that opens key 7, resulting in a signal from the output of switch 3 being recorded in the corresponding cell 5 memory and signal C of the synchronization unit 2 in the corresponding field of the cell of memory 8. At the same time, the signal from the output of the comparison unit -4 increases by one the value of the counter defined by the address received from the output of the synchronization unit 2 in the unit 9 of the counters. After the information from the output of the short-term indication unit 10 is received by the operator, through the input 12 of the device, it resets whose ci of the memory block 8 and resets the counter of the counter block 9 and starts the maximum determination unit 11. The maximum determination unit 11 determines in counter block 9 the number of the counter in which the maximum code is located. If in block 9 of the counters there are several counters with the maximum code, then the counter with the minimum number is selected. The counter address with the maximum code is fed from the output of the maximum-definition unit 11 to the input of the memory block 8. Then, the signal C2 from the memory unit to the brief indication unit 10 outputs the contents of the cell, the address of which was formed by the maximum determination unit 11. The signals C 1 and C2 are output alternately by the synchronization unit 2. If the operator changes the state of the object in the process of processing, this change is returned to the short indication block 10, since the address generated by the maximum definition block 1 does not change until the short term block 10 is erased by the operator indications. Compared with the known device in the proposed objects on. operator control is not chosen randomly, but only those that have currently undergone the maximum number of changes in their state. This makes it possible to reduce the amount of memory or increase the number of controlled objects while maintaining the functional characteristics of the alarm system. In addition, in the proposed device, all changes in the state of the object that occur during the processing of information about this object will be directly processed by the operator. In the known device, the arrival of these changes is blocked until the next processing cycle. Consequently, the proposed device allows more efficient processing of information about those objects that tend to change their state frequently.
