(54) DEVICE FOR CONTROL OF PARAMETERS OF OBJECTS

one

The invention relates to automated control and management systems for various objects.

Known are devices for monitoring the parameters of various objects, which include sensors, input key circuits, a switch, a setting setter, a comparison unit, and display control elements.

The disadvantage of existing devices is their low informational reliability, due to the possibility of issuing signals to the operator for the deviation of the parameters of the object being monitored for random interference at the system input and failure inside it.

The aim of the invention is to increase the efficiency of the control.

The goal is achieved by the fact that the device contains an operating unit, the first and second inputs of which are connected respectively to the outputs of two blocks of the right and fourth output of the switch, the first output of the operating memory unit is connected to the second inputs of the control elements; the second and third outputs are connected respectively to the third inputs of the comparison units to the input of the yo.mutator.

The drawing shows a block diagram of the device.

The proposed device contains input key circuits 1-3, setting control 4 settings,

switch 5, blocks 6 and 7 of the comparison, block 8 of the RAM, and elements 9-11 of the display control, sensors 12 of the primary information.

The operation of the device is as follows.

The output signals of the primary information sensors through the key circuits I-3 are alternately connected to the input of the comparator unit 6. The key circuits are controlled by switch 5, at the output of which combinations of ticks and units are changed. Each combination of ticks corresponds to the number of the connected parameter.

At the same time, the com switch 5 connects the corresponding settings of the monitored parameters through the setpoint adjuster 4 of the setpoints to the inputs of blocks 6 and 7 of the comparison, gives ticks "ten and" units to the display control elements 9-11 (mimic), preparing them to receive information from block 8 of the RAM, and outputs cycles of “units to the input of block 8.

The information comparison unit 6 compares the signals from the sensors with the corresponding settings, and outputs the signal "deviation or" no-pMa.

When each sensor is connected, the corresponding indication control element is prepared to receive information and

is turned on or off by a signal from the RAM block 8. Block 7 Comparison It is in reserve with respect to Block B, which ensures that P01 increases the reliability of the information presented to the operator. Switching to the backup comparison unit is performed from the RAM block 8 upon receipt of a "deviation in control cycle" signal.

If, when comparing any parameter with a setting, comparison block 6 generates a "deviation signal, then it goes to memory block 8 and is stored in it, but the next ten parameters are disabled and this top 10 parameters are polled VNOB.

At the same time, with the appearance of a deviation signal, block 8 generates a signal to monitor the health of this channel, one of the cycles of units to the input of block 6 Comparison sends the reference values of the setpoint and control signal. When the signal "Norm in control cycle and confirmation of the signal" is received, the deviation in the case of the secondary connection of the parameter by which the prior signal Deviation was issued, the RAM unit 8 generates a signal to activate the corresponding display control element 9-11.

If from block 6 of comparison, when the second connection of the parameter is received, the signal "norm is received, then switch 5 makes the third connection of the specified group.

This process in the device will be carried out before two successive connections of the same states "norm or" Deviation and receiving a signal "norm to the control cycle of the information processing channel, after which the mnemonic scheme will give information through the display control elements 9-1.1.

Upon receipt of the signal "deviation to the control cycle of the information processing channel control unit 8, it issues a signal to switch another comparison unit, after which the information is processed according to the same principle.

The system operates similarly for the cases of transition of parameters from the state of "deviation to state" of the norm, i.e., serial connection, control of Information Processing Channels and so on are also carried out.
