Description

one

The invention relates to automatic control systems and is intended for testing electrochemical integrators of discrete effects on reliability.

Devices are known for determining the parameters of discrete integrators by their charge and discharge, comprising a threshold device, a time measuring device, current generators, a control element, an integrator, reference and control units l.

The closest in technical essence to the invention is a device comprising a current generator, a time stamp generator, a time interval counter, a comparison device, a decoder, an indicator device, and a control circuit 2.

The disadvantages of this device are that it does not allow for repeated automatic cycling, as well as to keep track of the maximum number of charge-discharge cycles, at which the electrochemical integrator of discrete action is maintained, i.e. It is not intended to test online testing or reliability.

The purpose of the invention is to automate the process of testing discrete integrators for reliability.

The goal is achieved by the fact that a protection circuit whose output is connected to one of the inputs is added to a device containing a time stamp generator, a control circuit, current generators, temporary devices, a coincidence circuit, a comparison device, decoders and indicator devices. control circuits, and the input with one of the integrator outputs, and the counting circuit is a bit-for-5 rppd loop, containing a series-connected loop counter, a decoder and an indicator, the input of the loop counter being soyiisn through, introduced with logical key

0 by the output of the control circuit.

Pa drawing shows a block diagram of the device.

ycTp (oncTBG contains 1 time stamp generator, 2 times times counter, 5 charging times counter, 4 charging current generator 4, control circuit j, discharge current generator 6, matching circuit 7, logical keys 8-1.0, setting device 11 for charging time, discrete integrator 12, drish JipaTopbi 1 3 - 1,

indicator devices 16-18, comparison device 19, protection circuit 20, counter 21 cycles.

The device works as follows.

If it is necessary to transfer a certain amount of electricity to the integrator at a known value of charge current 3, the operator sets the required charge time tJ J Set charge time 11. The corresponding output of the decoder 15 of the counter 3 charge time is connected to the coincidence circuit 7. The charge time begins when the operator sends the Start command to the control circuit 5. By this command, control circuit 5 connects discrete integrator 12 to charge current generator 4 through logical key 10. At the same time, control circuit 5 and logical key 10 allow pulses to pass from the time stamp generator 1 to the charge time counter 3, the decoder 15 and the indicator 18. As the meter is filled, the indicator on the HOD indicator displays the charge time r of the discrete integrator. At the end of the specified charge time, the positive level from the decoder 16. enters the matching circuit 7, which, through the control circuit 5 and the logical switch 10, disconnects the discrete integrator 12 from the charging current generator 4, and the counter 3 charging time from the generator 1 of the time stamps. The final charge time is recorded on the indicator board. The operation of the device in the discharge mode is similar to the operation in the charge mode, but the integrator 12 is disconnected by a signal from the output of the comparison device 19 through the control circuit 5 and the logical key 8. At the end of each charge-discharge cycle, the control circuit 5 generates a pulse through the logical key 9 goes to the counter 21 cycles, the decoder 14 and the indicator 17. In case of failure of the tested discrete integrator 12, the protection circuit 20 through the control circuit 5 and the logical keys 8 and 10 disable the charge generator 4 and discharge 6 and stops the charge 3 and bit 2 counters. In this case, the indicator device 17 records the number of accumulated cycles.

The device allows automatic testing of electrochemical discrete integrators for reliability, since multiple automatic cycling and counting of the maximum number of charge-discharge cycles is performed, at which the operability of the tested integrator is maintained.
