The invention relates to instrumentation technology, can be used to determine and record the interconnected parameters of objects and is an improvement of the known device according to the author. St. No. 1164668.

The purpose of the invention is to expand the functionality of the device by automatically measuring and recording any number of three interconnected object parameters, i.e. obtain three-coordinate characteristics of the object.

The drawing shows a block diagram of a device for measuring and recording.

A device for measuring and recording the parameters of the control object 1, for example, a transistor, contains the first 2, second 3 and third 4 switching units, measuring units 5.1, ..., 5, N, the distributor 6, the first 7 and second 8 registration units, the unit 9 synchronization, an additional 10 measuring unit, the third registration block 11, trigger 12, additional distributors 1 3. 1, ... , 1.3 .N, 13, N + 1,

The initial temperature is, for example, 0 ° C.

Since the process of setting the required temperature has a substantial time duration (in the order of h :), a delay is required for this time for the further operation of the entire device. This delay is implemented using a frequency divider 18, which has a conversion factor M and a signal delay at its output corresponding to M clock pulses.

With the appearance of this signal (after 1 h), the following processes occur: using a meter with 20 threads. the third block of the 1I registration is measured and recorded in

steady state temperature in the thermostat and, therefore, the temperature of the object I of the control placed in the thermostat is also recorded;

the element OR 14, the delay unit 15, the two initial set-ups of the state of the element AND 16 and 17, the divisor 18 of the first and first bits of the distributors 6 and

13.1; connection using blocks 2–4 of switching outputs of the object 1 of the control and inputs of blocks 7, and

then you.

Additional IO measuring

the block is designed as an adjustable

a thermostat 19 with a temp-registration meter 20 to the measuring blooring, the output of the latter being connected to the first input of the third registration unit 11, and the control inputs of the adjustable 19 urostat to the corresponding second outputs of the additional-13.N + 1 distributor.

The device works as follows.

In the initial state, the trigger 12 is found, the cysts are in the single state, and the frequency divider 18 is in the zero state, the pulses of the synchronization unit 9 are absent. Object 1 control is disconnected from the measuring units 5. 1,. . . , 5.N, from the outputs of which the blocks 7 and 8 of the registration are also disconnected.

When a button (not shown) is pressed in the synchronization unit 9, a pulse appears at its second output, look for the initial setting to state I. The first bit of the additional distributor 13., and at the first output the clock pulses coming through the open element 5.1. (due to the installation of the first bit of the distributor 6); set to state about trigger 12, closes

40 element 16 and element 17 is opened, which leads to stopping the frequency divider 18 and the arrival of clock pulses on the second actuators 13.1, ..., 13.N and on

5 input block 15 delay.

Measuring units 5.I, ..,, 5.N on signals of distributors 13.1, ..., 13.N consistently in time measure the characteristics of object 1 of control at a given set temperature. The registration blocks 7 and 8, controlled by the clock pulses arriving through the delay block 15 and connected by blocks 2 4 according to the signal of the distributor 6 synchronously with the control object 1 to the measuring blocks 5,1, ..., 5. N, are also produced sequentially time registration of these characteristics.

The signal from the output of the first bit of the additional distributor 13.N + 1 in the thermostat 19, in which the object 1 of the control was placed, installed

The initial temperature is, for example, 0 ° C.

Since the process of setting the required temperature has a substantial time duration (in the order of h :), a delay is required for this time for the further operation of the entire device. This delay is effected by means of a frequency divider 18 having a conversion factor M and a signal delay at its output corresponding to M clock pulses.

With the appearance of this signal (after 1 h), the following processes occur: using a meter with 20 threads. the third block of the 1I registration is measured and recorded in

steady state temperature in the thermostat and, therefore, the temperature of the object I of the control placed in the thermostat is also recorded;

Measuring units 5.I, ..,, 5.N according to the signals of the valves 13.1, ..., 13.N consistently in time measure the characteristics of the object 1 control at a given steady-state temperature. Blocks 7 and 8 of registration, controlled by the incoming clock through a block 15 of delays by clock pulses and connected by blocks 2-4, synchronously with object 1 of control to measuring blocks 5,1, ..., 5. N, are also produced sequentially time registration of these characteristics.

Clock signals to the valve 6 are received through the element OR 14 from the first outputs of the valves 13.1 ,, .., 13.N.

When the NK-ro clock pulse (where K is the number of measured points of each characteristic) arrives at the second inputs of the distributor 13, the last K-th digit of the N -th distributor 13.N triggers (i.e., as a result, a signal is transmitted through the OR 14 element to the operation of the last N-ro bit of the distributor 6, to the installation of the trigger 12 to the state 1 and to the clock input of the additional distributor 13. N + 1. In the latter, the first discharge is triggered and set to state 1 of the second discharge. At a signal from this discharge in thermostat 19, heating starts to the temperature of the next measurement point of the characteristics, for example, JU.

The second measurement cycle begins, in which, as in the first cycle, the time delay for heating thermostat I9 is delayed by dividing the clock frequency pulses with a divider 18 (since trigger 12 is in state T, element 16 is open and element 17 is closed).

After a time delay on the signal of the divider 18 frequency occurs

rhenium and temperature registration of the object-35 to the second input of the first element I, and

This one is the control, and then the measurement of its characteristics is the same as in the first measurement cycle.

After the end of the second cycle, the third cycle begins (at 30 ° C), etc. to L-ro cycle (for example, up to 100 C).

After the end of the L-ro cycle, the last L-th bit of the distributor 13 is triggered. N + 1, the signal from its output,

enters the input of block 9 synchronization-45 by the inputs of the additional measurement and stops its operation. The clock pulses stop and the device returns to its original state.

Thus, by introducing an additional distributor and a measuring unit, a registration unit, a frequency divider, a trigger and two elements And, it is possible to automatically register the values of any number of three interrelated parameters of control object 1 sequentially in order to build their functional dependence, which expands device functionality
