Abstract

The invention relates to telemechanics and can be used in telemechanical systems for various purposes, information transmission systems and automated control. The aim of the invention is to simplify the device and increase its noise immunity. The goal is achieved by introducing a pulse former. The device receives telemetry information and writes it to the buffer register with the Receive Enable command, as well as the subsequent connection. This eliminates the possibility of distortion of information during storage, as well as the possibility of its premature dumping, the implementation of a pulse shaper is possible, for example, on a multivibrator in standby mode. 2 Il.

The invention relates to telemechanics and can be applied in various telemechanical systems and automated control systems.

The purpose of the invention is to simplify the device and increase noise immunity.

FIG. 1 is an electrical block diagram of the device; in fig. 2 - signal plots, explaining the principles of operation of the device.

The device contains cells 1-1, ..., 1-p register, element OR 2, first 3 and second 4 elements AND, first 5 and second 6 triggers and driver 7 pulses.

The information inputs of bits 1 of the register and the inputs of the OR element 2 are connected to the inputs of the device, and the output of bits of the 1 register to the outputs of the device.

Input The device reception permission is connected to the first input of the first element I 3, the second input of which is connected to the output of the second trigger 6, the first input of which is connected to the input End of removal of the device. The output of the pulse former 7, for which, for example, a waiting multivibrator can be used, is connected to the second inputs of the triggers 5 and 6, as well as to the first control inputs of the bits of the register 1.

These inputs of the register bits are given a signal that ensures the recording of information received at the information inputs of these cells.

Element OR 2 and trigger outputs

5 connected to the inputs of the element And 4, the output of which is connected to the input of the driver 7 pulses. The output of the first element And 3 is connected to the second control inputs of bits 1-1 ......

..., 1-n register. The signal applied to these inputs ensures that the register bits are set to the zero state.

The device works as follows.

The initial state of the triggers 5 and

6HyJieBoe, i.e. At the direct output of flip-flop 5, there is O, and at the inverse output of flip-flop 6 there is a signal 1 (Fig. 20.0. The output signal from flip-flop 6 arriving at the second input of the And 3 element allows the passage of a signal through it) devices

before the start of reception (Fig. 26). This signal, having passed through the element 3 (fig. 2e), is fed to the inputs of the register bits, resetting them to the zero state, and to the first, the input of the trigger 5, sets it to the one state, at which signal 1 starts to arrive at the first input of the element 4.

After the termination of the signal, the reception of the inputs of the device receives information. A pulse (Fig. 23) appears at the output of the element OR 2, which, entering through the element 4 (Fig. 2e), starts the pulse shaper 7 on the waiting multivibrator for a time t. This time is chosen from the condition for ensuring stable recording of information in register 1.

The signal from the pulse driver output to the first control inputs of the register bits ensures that information arriving at the device inputs is recorded in them.

At the same time, this pulse arrives at the second input of the trigger 6, transferring it to the unit state. The inverse output of the trigger 6 has a low potential, which acts on the second input of the And 3 element and blocks the passage of the Acceptance signal through this element. If interference is now appearing at the input of the device reception resolution, it does not reset the information recorded in the register. At the end of a single pulse produced by the pulse shaper 7, the trigger 5 switches to the state O, and a low potential appears at its output, which prohibits the passage of information through element 4. Now, before the information is sampled in the channel, interference occurs will not distort the information recorded in the register.

After receiving information from the register, a signal is received at the input of the device End of removal (Fig. 2e), in which the trigger 6 is set to the zero state (Fig. 2a), and the device, having returned to its initial state, is ready to receive information again.
