(54) DEVICE FOR MULTICHANNEL CONTROL

The invention relates to instrumentation engineering, in particular to devices for multichannel control of parameters.

A device for monitoring is known, comprising sensors for monitoring parameters, a switch, a control unit and an analyzer for monitoring parameters 1.

The closest technical solution to the present invention is a device for multichannel monitoring, containing a serially connected distributor, switch, key, analyzer of monitored signals and a signaling control unit, the second key input is connected to the output of the equivalent signal generator {2}.

The purpose of the invention is to increase the reliability of the device.

To do this, a RAM unit is inserted into the device, the address inputs of which are connected to the output of the distributor, and the output is connected to the third key input, the output of the control and signaling unit is connected to the recording input of the RAM.

The drawing shows a block diagram of the device.

The device contains sensors I, switch 2, distributor 3, key 4, Equivalent SNG generator 5, operational unit

the memory 6, the analyzer of the monitored signals 7, the control and signaling unit 8, the counter 9 of the number of parameters that failed from the norm.

The device works as follows. The monitored parameters from sensors 1 are transmitted through switch 2 to key 4. Another key input is connected to an equivalent signal generator. The key connects to its output or a signal from the date-. The key 1 or the signal equivalent to the sensor sensor from the generator 5. The key inputs are equalized from the output of the operating memory block 6, which, when the parameters are normal, controls the key 4 so that the measured parameter is connected to its output.

The switch 2 and the RAM unit 6 when switching sensors are controlled synchronously by the valve 3.

When the sensor parameter goes beyond the tolerance norm, this event is fixed by

the signals of the analyzer 7, the control unit of the alarm system 8, the counter 9 and the memory unit 6. Thus, the information on the address of the sensor corresponding to the parameter beyond the tolerance field and their total number is displayed. At the operator's command, block 6 records the sensor's address, after which the sensor is disconnected from the device input, and during subsequent control cycles, the RAM block 6 will generate a signal for connecting the input of the generator of equivalent signals 5 to the output of key 4 when polling the corresponding sensor. The use of this device will significantly reduce the number of wiring connections, increase the number of inputs of the switch and increase the reliability of operation. Claims An apparatus for multichannel monitoring, comprising a sequentially connected distributor, switch, key, analyzer of monitored signals and a control and signaling unit, the second key input connected to the output of an equivalent signal generator, characterized in it has an operative memory block, the address inputs of which are connected to the distributor output, and the output with the third key input, the output of the control and signaling unit is connected to the recording input memory block.
