The invention relates to automation and can be used software-time control systems and time delay devices,

Known devices for parameter control, containing a control unit, a computing unit, an input switch, an output switch and an indication unit [1].

The disadvantages of these devices are their complexity associated with the presence of a relatively complex computing device,

The closest technical PE ₁ k the invention is an apparatus for tolerance control parameters, comprising a control unit triggers, the input and output switches, pulse shapers, j decoders, a display unit and a source of controlled parameters [2 ^ ·

However, in this device, the parameters of the object are monitored due to the presence of 2 switching performed by the input and output switches, which leads to an increase in the monitoring time.

The purpose of the invention is to increase the speed of the device.

This goal is achieved by the fact that in the device for parameter control, containing an indication unit, a control unit connected to the output with zero inputs of the triggers and to the output of the device, the inputs of which through pulse shapers are connected to the first inputs of the first elements And connected to the outputs with the unit inputs of the triggers, a rectangular pulse generator, a second element AND, an element NOT and a third element AND, inputs connected to the unit outputs of the triggers, and the output with the first input of the display unit and with the input elem NOT-coagulant, the output of which is connected to the first input of the second AND gate coupled with a second output.

In FIG. 1 is a functional diagram of a device for tolerance control of parameters; FIG. 2 - temporary diachrams of the device operation (a - in the case of normal operation of the controlled object, b - in the case of the departure of the and -th parameter outside the tolerance).

The device comprises a control unit 1, a control object 2, a rectangular pulse generator 15 .3, the first AND 4 elements, 5 pulse generators, triggers 6, the second AND element 7, the HE element 8, the third AND element 9, the indication unit 10, output 11 control unit 1 20, the first output 12 of the generator 3 pulses, the output of the 13th generator 3, the signal 14. the end of the generator 3, the first output 1 Parameter) of the control object 2, output 25 the 16th (parameter) control object 2, output 17 of the shaper 5-1 pulses, output 18 of the shaper 5-L pulses, output 19 of the element And 4-1, output 20 e element 4 and output 210 trigger ³⁰ ger 6-1, output 22 trigger 6 p, output 23 of the third element 9, output 24 of the element 8, output 25 of the second element 7, state 26 of the display unit 10 .., ³⁵

The device operates as follows. ·

By the signal of block 1, the triggers 6 are set to their initial state, · ₄ θ starts the generator 3 and starts the object 2 of the control (for example, the program-time mechanism) -. At the output of the generator 3, voltage pulses are formed, the beginning and the end of which ₄₅ set the tolerance field of one of the monitored parameters (Fig. 2, pos. 12.13). These voltage pulses are supplied to the inputs of elements And 4. At the moments of the appearance of signals at the ₅ θ outputs of the control object 2 (Fig. 2, pos. 15,16), the corresponding pulse shapers form short voltage pulses (Fig. 2, pos. 17,18 ), which are fed to other inputs of the element of ~ ₅₅ and AND 4. In the case of normal functioning of the control object 2 (Fig. 2, a) at the outputs of And 4 elements ₍ voltage pulses appear (Fig. 2, a, pos. 19,20) which are triggered by triggers 6. On all inputs of the And 9 element, single signals appear and on the output of this element appear Xia signal Norm "input to the display unit 10. The output of the second AND element 7 in this case no fault signal.

In the event that any parameter is out of tolerance. (Fig. 26, pos. 16) the pulses at the inputs of the corresponding element And 4 do not coincide, and there is no signal at the output of this element (Fig. 2, b, pos. 20) The corresponding trigger 6 remains in the zero state (Fig. 2, b , pos.25) and therefore, the signal at the output of the element And 9 is absent .. At the same time, a single enable signal from the element NOT 8 is received at one input of the And 7 element (Fig. 2.6, pos.24).

At the end of the test cycle, the generator '3 generates a signal about the end of work (figure 2, pos14). On this signal from the output of the second element And 7 in the display unit 10 receives a signal Failure.

The technical and economic effect of the introduction of the device is to increase labor productivity in control and testing operations. The monitoring time is reduced depending on the parameters of the controlled objects 1.5-15 times.
