Abstract

The utility model relates to control systems and can be used, in particular, for the operational control of the operating modes of the radar station and the full automated operational control of the operability of the mechanisms included in the radar station. The control and monitoring device has a control unit, sensors connected to controlled mechanisms, a logical processing unit and an indication unit. The logical processing unit consists of microcircuits made on AND-NOT, OR-NOT, and RS-triggers. During the operation of the radar station, the logical processing unit processes the signals received from sensors built into the monitored mechanisms, and gives a signal about a malfunction of some mechanism to the display unit, while blocking the supply of malfunction signals to the display unit of other controlled mechanisms.

Description

The utility model relates to control systems and can be used, in particular, for the operational control of the radar station operating modes, for the full automated operational control of the operability of all the mechanisms included in it, and for displaying information about their status through the logical processing of signals from sensors that are built-in into the mechanisms of the radar station, as well as checking the health of indicator elements.

A multi-channel device for monitoring logical blocks is known, which contains a memory element, a NOT element, an indicator, a comparison circuit, an input detection unit and a reference unit in each channel (AS USSR No. 1038947, class G06F 11/22, 1982).

A device for monitoring the condition of equipment containing a load device of the stand, a computer with symbol processing of information and a preliminary diagnostics unit, an accurate diagnostics unit, a fault selection unit, a RAM unit and a memory unit, a digital-to-analog unit, an analog-to-digital unit and a unit for measuring transformations (patent RF №2131138, CL G05В 19/00, 1996).

These devices are intended for diagnostic monitoring and do not allow checking the operability of devices in automatic mode, and the presence of a large number of blocks and elements leads to a decrease in reliability and complication of the device.

The closest analogue is a device for indicating the root cause of a malfunction in functionally coupled systems, comprising a display unit and sensors that are connected to the mechanisms of the controlled system (AS USSR No. 496559, class G06F 11/30, 1970).

However, this device does not unambiguously identify a faulty block of the monitored system, since it displays all subsequent blocks as faulty. Therefore, in the presence of a large number of blocks with complex connections in the system, it is difficult to clearly determine the faulty block.

The task to which the proposed utility model is aimed is to create a control and monitoring device that allows you to quickly manage the operating modes of the radar station and conduct a full automated operational control of the operability of all the mechanisms included in it.

The technical results in the implementation of the utility model are: improving the reliability of the radar station, increasing the speed of information processing, conducting a full automated operational control of the health of all its mechanisms, checking the health of indicator elements.

The following essential features influence the achievement of these results: the control and monitoring device has a control unit, sensors, a logical processing unit, and an indication unit. Moreover, the control unit is connected to the logical processing unit and to the controlled mechanisms, the sensors are mounted on the controlled mechanisms and connected to the logical processing unit, and the logical processing unit is connected to the display unit.

Distinctive features of the prototype in the proposed control and monitoring device is the presence of a control unit and a logical processing unit, which is a set of microcircuits made on logical elements AND-NOT, OR-NOT and RS-flip-flops, as well as the implementation of communications between the elements of the control and monitoring device .

Figure 2 presents a schematic diagram of an electrical circuit block of a logical processing.

The control and monitoring device comprises a control unit 1, sensors 2 of the controlled mechanisms 3, a logical processing unit 4, an indication unit 5.

Logical processing unit 4 consists of four circuits 6, logical element 7 4 OR, NOT, RS-trigger prohibiting the signal 8. For every eight monitored mechanisms 3 of the total N quantity, one circuit is used 6. Scheme 6 contains eight logic elements 9 2 AND-NOT , eight RS-flip-flops 10, eight logic elements 11 2 OR-NOT, logical element 12 8 AND-NOT. Circuit 6 has eight inputs 13 from sensors 2, inputs 14, 15 from control unit 1 and eight outputs 16 to display unit 5.

Control unit 1 has N + 2 inputs. The first output of the control unit 1 is connected to the input 14 of the logical processing unit 4, the second output of the control unit 1 is connected to the input 15 of the logical processing unit 4, the remaining N outputs of the control unit 1 are connected to the corresponding inputs of the controlled mechanisms 3, the outputs of the N controlled mechanisms 3 are connected to the corresponding the inputs of the sensors 2, the outputs of the N sensors 2 are connected to the corresponding inputs 13 of the circuits 6, N outputs 16 of the circuits 6 are connected to the corresponding inputs of the display unit 5.

An input of 13 _m (where M is any of the total N number) is connected to the first input of the logic element 9 _m 2I-NOT, the second inputs of the logic elements 9 2I-NOT connected to the inverse output of the RS-trigger of the signal inhibit 8. The output of the logic element is 9 _m 2I-NOT connected to the S-input of the RS-flip-flop 10 _m , the R-input of the RS-flip-flop of the signal inhibit 8 and the R-input of the RS-flip-flops 10 are connected to the input 14, the direct T-output of the RS-flip-flop 10 _{m is} connected to the first input NAND gate 11 _m-NO 2 or, the second inputs of AND gates 11 2or-NO elements are connected to the input 15, the output of NAND gate 11 _m 2yl -NOT in each circuit 6 is connected to one of eight inputs

logical element 12 8I-NOT and with an exit of 16 _m . The output of the logic element 12 8I-NOT of each circuit 6 is connected to one of the four inputs of the logic element 7 4OR-NOT, the output of the logic element 7 4OR is NOT connected to the S-input of the RS-trigger of the ban signal 8.

The control and monitoring device operates as follows.

The operation modes of the controlled mechanisms 3 and control modes are controlled by push-button and slide switches installed on the front panel of control unit 1.

When the controlled mechanisms 3 are operating from the control unit 1, the input 14 of the logical processing unit 4 is supplied with a pulse signal “0” (reset) and the RS-trigger for inhibiting the signal 8 and RS-triggers 10 are brought to the zero state, appears on their direct T-outputs the signal is "Log.0", and the signal "Log.1" appears on the inverted outputs. If the “Log.0” signal (no malfunction) is received at the 13 _m input, then the “Log.1” signal will appear at the output of the 9 _m 2I-NOT logic element, which will not change the state of the 10 _m RS-trigger, i.e. on the direct T-output of the RS-trigger 10 _{m there} will be a signal “Log.0”. At the output of the logic element 11 _m 2, the signal “Log.1” appears, which is not displayed at the output of 16 _m in the display unit 5. If a signal “Log.0” is received at all inputs 13 from the sensors 2, then the output of the logic element 7 4 OR NOT, a “Log.1” signal will appear, which will leave the RS-trigger to disable signal 8 in the zero state, i.e. at the second input logic elements 9 2I-NOT signal remains "logic 1", which permits passage of the signal "logic 1" (failure) to the inputs 13. On admission to the input 13 _m "logic 1" signal from the sensor controlled _2m mechanism 3 _m , at the output of a logic element 9 _m 2I-NOT a signal “Log.0” will appear, which will set the RS-trigger 10 _m to a single state, i.e. on the direct T-output of the RS-trigger 10 _{m there} will be a signal “Log.1”. At the output of the logic element 11 _m 2, the signal “Log.0” will appear, which will be displayed at the output of 16 _m in the display unit 5. At the output of the logic element 7 4, the signal will appear

"Log.0", which will set the RS-trigger to prohibit the signal 8 in a single state, i.e. at its inverse output there will be a “Log.0” signal, which at the second input of logic elements 9 2I-NOT will prohibit the passage of the signal “Log.1” along the first inputs of 13 logical elements 9 2I-NOT. A malfunction of the controlled mechanism of 3 _m will be displayed on the 16 _m output in display unit 5 until the pulse signal “0” (reset) is received from control panel 1 to input 14.

In the health monitoring mode of display unit 5, “Log.1” signal is input to input 15, “Log.0” signals appear at the outputs of logic elements 11 2 OR NOT, which are displayed on outputs 16 in display unit 5. No signal for any output means a malfunction in the display unit 5.

Thus, the control and monitoring device provides operational control of the operating modes of the radar station, conducting full automated operational control of the operability of all mechanisms included in the radar station, and verifying the health of indicator elements.
