unit 20, switch 27, the inputs of which are connected to the corresponding second inputs of switch 26, and the common output is connected to the control potential source (ne figure 1 is not shown),

Any material objects (products) can be considered as objects having a resource that they spend in the process of functioning. The amount of consumption of this resource per unit of time is influenced by various factors, including the operating conditions, therefore the service life of the product tr under the influence of non-stationary operating parameter T is related to the magnitude of this operational parameter by the functional dependence Tr tr (T).

The operational parameter can be, for example, voltage, current, mechanical and climatic effects, etc., as well as their complex effect on the product.

The change in the intensity of the impact on the product occurs in a discrete manner, as shown in the diagram (Fig. 3). moreover, the number of discrete values of the operating parameter p 4. Each such value corresponds to a specific numerical value of the resource consumption per unit of time and, consequently, the mode of operation.

Assume that the mode of operation in the tcrti section corresponds to unproductive consumption of the resource, for example, work of the product in the Standby mode, in sections ti-t2, t2-T3, ts-t4 is the productive consumption of the resource, but assume that the section is with increased consumption per unit time, for example, product operation in overload mode.

In the diagram (fig. 3), the modes of operation are designated by numbers 1-4. specifying the nominal values of resource consumption by unproductive and increased operating modes as in the total form, i.e. during the whole period of product operation, as well as simultaneously, i.e. Continuously consumed resource can increase the useful life of the product at a given amount of resource, for example, minimizing the time the product operates in operating modes 1 - Standby and 4 - Overload-. ka

The device can operate in two modes: in the mode of automatic connection of a group of information outputs of one of the integrators 10.1-1 On to

the fourth input of the display unit 6; in manual connection mode.

In the future, the device will be considered in automatic mode.

connection, for which the switch 26 is set to a position in which the inputs of the unit 20 are connected to its common outputs (Fig. 1).

The device works as follows.

The signal from the output of sensor 1 is fed to the inputs of the threshold elements 7.1-7P and to the input of the nonlinear function converter 2. Depending on the input level

The signal b at the outputs of the corresponding threshold elements 7.1–7 p is set to signal 1 if the signal exceeds the threshold of the threshold element, or the signal 0 if it is less than the threshold.

0 triggered.

The state of the outputs of elements 7.1-7p connected to block 8, depending on the mode of operation, will correspond to the values given in the table of standing (FIG. 4 ai-an).

Depending on their value, a signal 1 is set at one of the outputs of the Ach-An of block 8, and the signal O is set at the others (Fig. 4).

Signals from the outputs of the control unit 8

integrators do:

- to the inputs of block 20 and further through the switch 26 to the inputs of the setting unit 25 of the address, which is controlled by the signal 1. Depending on which of the inputs of the setting unit 25 of the address receives the signal 1, the operating mode code is set to the output group of the latter, i.e. . the address of the integrator, in which the resource consumption is monitored in the established operating mode, and the output group of the first 11 multiplexer is connected to the output group of the corresponding integrator;

5 - to the inputs of the setting unit 18 of the address, which is controlled by the signal 1. Depending on which of the inputs to the setting unit 18 of the address receives 1, the mode code is set on the group of outputs of the latter

0 operation, in which the output of the corresponding logical element And through the second 12 multiplexer is connected to the information input of the counter 16 of a continuously consumable resource, and to the second

5 to the input of the comparator unit 17, via the third 13 multiplexer, connects the output group of the corresponding setpoint of the code of the continuously consumable resource of the setpoint adjusters 19.1-19p of the code of the continuously consumed resource;

- a reset 14.1-14p is applied to the inputs of the corresponding pulse formers, while the driver, at the input of which a signal 0-1 transition occurred, generates a pulse Reset, which through the OR 15 element enters the Reset input of counter 16, sets it to the zero state. Consequently, when the operation mode of the product is changed, the counter 16 of the continuously consumed resource is reset to the initial-zero state;

-to the second inputs of the AND 9.1-9p element, while the And elements, the second inputs of which receive the signal O, are locked and the O signal is set at their input.

The signal from the output of sensor 1 is converted by a nonlinear functional converter 2 into a sequence of pulses whose frequency is proportional to the rate of consumption of the life of the monitored product, which goes to the information inputs of the residual life counter 4 and the consumed life counter 5, while in the counter 5 the count of impulses arriving at its input during the entire time of operation of the product, and in the counter 4 during the time of the operational product is subtracted the pulses arriving at its input from a number loaded at the start of operation of the unit from the setting device 3, equal to the product operation life (the initial entry signal is not shown); on the first inputs of elements And 9.1-9p.

From the output of the element 9.1-9p, to the second input of which, from the control unit 8 of the integrators, signal 1 is received, a sequence of pulses is received: to the input of the corresponding integrator of the group of integrators 10.1-1 On, whose output group is connected via multiplexer 11 to the input of block 6 indications; to the corresponding input of the multiplexer 12, the output of which is connected to the input of the counter 16, where it is counted during the time of continuous operation of the product in the prescribed mode of operation.

In the case when the number registered in the counter 16, arriving at the first input of the comparison unit 17, exceeds the set value of the resource consumption during continuous operation of the product in this operation mode, it enters the input of the comparison unit 17 from the output group of the corresponding setting device 19.1-19p multiplexer 13, at the output of the comparator block 17 a signal is generated Violation of the rules of continuous operation in this mode of operation.

The signal from the output of the comparator unit 17 is fed to the input of the display unit 6 for light and sound signaling and to the output bus 21 of the device and can be

used to control the mode of operation of the product.

In the event that any mode of operation of the product is not regulated by the continuous consumption of the resource, for example,

0 sections 2 and 3 of the diagram (fig.Z), then the corresponding input of multiplexer 12 must be disconnected from the output of the corresponding element AND of the group 9.1-9P and connected to the zero bus of the device.

5 In this case, when operating the product in modes 2 and 3, the information input of the counter 16, the pulse sequence from the output of the nonlinear functional converter 2 will not be received and

0, the counter 16 in this operation mode will be in the initial - zero state.

Thus, the total value of the resource located in the counter 5, consumed by the product during an arbitrary length of time of operation, is represented in the device in the form of the key number.

The value of the consumed product

0 for an arbitrary length of time for operating the resource separately for each mode of operation, is represented in the device as numbers in the group of integrators 10.1-10P. Value

5 the residual life of the product after its operation for an arbitrary length of time is represented as the ROCT number in the residual life counter 4, and the value of the initial resource of the product is in the form of the RO number in the initial resource code setpoint 3.

For example, pulse counters with memorizing information can be used as integrators in the device.

5 when the power supply is turned off.

When operating the device in the mode of manual connection of the output group of one of the integrators 10.1-10P to the fourth input of the display unit 6, you must install

0, the switch 26 is in a position in which the inputs of the switch 27 are connected to its common outputs, while the address setting unit 25 is controlled by the switch 27. The integrator control unit 8 operates as follows.

The signals at the outputs Ai-An, depending on the value of the input signals at the inputs of the integrator control unit 8, have the following analytical expressions:

And aia2; ..; an-i an, A ai a2, ...; an-i an,

A ai E2; ...; an-1 an,

A ai a2; ...; an-i an.

The device allows you to more correctly organize the process of operating the product, thereby increasing the useful life due to regulating the time of the product in non-productive modes and increased resource consumption; determine the utilization rate of the product resource (the ratio of the useful expended product life, in the example given R2 + Rn, to the expended resource Ri -I-R2 ++ Rn RMS and make

conclusions about the correctness of its operation.
