Claims

20, the memory makes it impossible to document the sequence of time parameters without reducing the measurement speed. 3 The aim of the invention is to expand the functionality of the device. The goal is achieved by the introduction of a memory unit, a time unit, a control unit connected by a first output to the first input of the counter, a memory unit, a registration unit, a time control unit. intervals and a code converter connected by an input with a switch output, a first output through a time meter — with a first input of a memory unit, and a second output through a time interval monitoring unit catching - with the input of the control unit connected by the second output to the second input of the memory unit, and the third output - to the first input of the recording unit connected by the second input to the output of the memory unit, and the output - with the second input of the counter connected by the third input to the output of the meter time, and the output to the third input of the memory block. The drawing is a block diagram of the device. It contains a switch 1, a code 2 converter, a time meter k, a memory block k, a recording block 5, a time interval monitoring block 6, a control block 7, and a counter 8. The device operates as follows. The monitored time parameter in the form of two parallel potential or pulse signals start and stop is fed to the input of switch 1. In the converter, code 2 is parallel, the signal code is converted into a sequence of two pulses fed to the input of time meter 3 and to a constant potential applied to the input of the control unit time intervals 6. In the time meter 3, the time interval is directly measured by the start and stop signals in digital form. Simultaneously with the measurement of time in block 6, the received sequence is compared with the specified one. In the case of a corresponding signal to the control unit 7, the signal is generated to allow information rewriting in memory block k at the address provided by counter 8, the memory capacity of block t determines the maximum number of monitored time parameters that can be achieved by increasing the basic configuration consisting of blocks 3, 5, 7 and 8 by switch 1, code 2 converter and block 6. The extension is performed by combining the outputs of code 2 converters between themselves and the outputs of time interval control blocks 6 between each other, Pe, the counter version 8, in the forward run, addresses the recording of information from digital time meter 3 to memory block k, and during the reverse counting it addresses addressing information read from memory 4 to registration block 5. At the end measurement of a specified number of time slots stored in memory 6 — control unit 7 outputs signals for switching counter 8 from direct to reverse mode and memory 4 to reading mode. The change of the states of the counter 8 is carried out in the recording mode by the signals from the time meter 3, and in the read mode from the register-. At the end of the read mode, the counter 8 comes to the state O, which is a signal of the end of the monitoring process. The effectiveness of the proposed device is expressed in extending the functionality in several directions. The device allows, in the automatic mode, simultaneously with the measurement of time intervals, to control the number and sequence of their follow-up and to document the results of the control without reducing the speed of the control. The proposed device structure allows, by simply building up a small part of the equipment, to increase the number of controlled time parameters. Thus, the proposed device eliminated hardware. redundancy in the control of multichannel discrete devices by about kQ%, and the quality of control and reliability is improved.
