Description

This invention relates to telemechanics.

Multichannel code-pulse telemetry devices are known, containing sensors, the outputs of which are connected to the inputs of KONtMyraTOpa, connected by an output to an analog-to-digital receiver, the output of which is connected via a converter to the control input of the switch fl.

The drawbacks of the device are the limited functionality, the impossibility of realizations of the mode G telemetry - television signaling

A device for telemetry and remote signaling is known, containing telemetry sensors, the outputs of each of which are connected via the corresponding matching element to the inputs of the first switch connected to the first input of the integrator of the first pulse-width converter integrated in the form of connectedly integrated integrator

And a comparator, remote signaling sensors, a code-analogue converter, the output of which is connected by a signal. W-To kokgmutator connected to the output. home to the first integrator of the second pulse width converter, implemented; As a series-connected integrator and kok parator, the outputs of each short-circuit comparators of pulse-neutral converters are connected to the trigger inputs, one output of which is connected to the second integrator input of the first and pulse converters device output, another trigger trigger is connected to the second axis of the integrator of the second pulse-width converter, the input clam y 2.

The disadvantage of the device is a constructive complexity, and, as a result of this, low reliability, due to the use of a large number of code-analog converters.

The purpose of the inventive is to simplify the device, and to increase the reliability of its operation.

The goal is achieved by the fact that an additional switch is inserted into the device, the inputs of which are connected to the outputs of the telestyle sensors; From the 1S, the output of the additional switch is connected to the input of the code equivalent converter, the control inputs of the switches are connected to the INPUT terminal of the device. .

The dryness of the invention is explained using the block diagram of the device shown in the drawing. The device contains telemetry sensors 1, .- 1 matching elements 2, -2}, the first switch 3, the integrator 4 / and the comparator 5 of the i-th pulse-width pulse, the converter, the trigger b, the Tf-Vf sensors, the additional switch 8, converter code analogue 9, second switch 10, integrator 11 n kosharator 12 second pulse-width converter,:

The device works as follows. When a command signal arrives from the input terminal to the switch, the first switch 3 connects to the input of the first quarter-pulse converter a specific dAT to tele-measurement 1. WITH; matching element 2 -2, a-additional switch 8 connects a certain group of sensing sensors 7-7 to the converter input code analog 9, the second switch 10 connects the converter analog output 9 to the input of the second pulse width converter.

Depending on the magnitude of the signal arriving at a given element of the matching signal, the first pulse-width converter creates a pulse of a certain duration and switches trigger 6, thereby permitting the operation of the second pulse-width converter. Depending on the state of the telemetry sensors 1 -1, the code-analog converter 9 generates a certain signal, the value of which: determines the duration of the pulse generated by the second latitude-impedance generator. With the falling edge of this pulse, trigger 6 returns to its initial state and the first pulse-width converter starts operating. The process is periodically repeated as long as the command signal is present.

The use of a single code-analog converter and an additional switch, simultaneously performing the function of receiving and transmitting information from sensors that change their state, favorably distinguishes the proposed device from the prototype, since it is different. e4x |) efficiency and reliability of operation, simplifies to 1 structure, reduces the cost of manufacturing and setting up large quantities of predivision converters code-analogue, photo spectrum, a device for telemetry to tele-signaling, containing sensors for telemeasuring, outputs of each of which, through the corresponding matching element, are connected to the inputs of the first switch, connected by an output to the first input of the integrator of the first width-impedance converter, executed in the form of successively The integrator and the comparator, the remote signaling sensors are a code-analog converter; the output of which is connected to the output of the second switch connected to the first input of the integrator. The second pulse-snooter. converter, made in the form of serially connected integrator and; comparator, outputs of Comparators of each of the ash-source-converter converters / connected to the trigger inputs one output of which is podkhozhuchu ko. to the second input of the integrator of the second pulse-width-of-the-slant production of a tel. An input terminal, characterized in that, in order to simplify the device and increase it. reliability, an additional switch is introduced into it, the inputs of which are connected to the outputs of the Remote Sensing Sensors, the output of the additional switch is connected to the input of the code-analogue converter, control of the & inputs of the coeAHiieiai switches with the input terminal of the device .;
