To illustrate the operation of the AUVM TP complex, examples are offered:

Example 1

An example of the application of the AUVM TP complex in the domestic industry (smart home) is the control of street and corridor lighting of a mansion (cottage) depending on external natural lighting and time of day.

The task of domestic use (smart home) is when dusk sets in, first the corridor lighting of the mansion is turned on (as the room darkens faster than on the street), then the street lighting of the mansion is turned on. At one in the morning, the corridor lighting of the mansion turns off (everyone goes to bed), and the street lighting of the mansion turns off in the morning when it becomes light.

For the functioning of such a technological process on the basis of the AUVM TP complex, it is necessary to connect a corridor lighting system, a street lighting system, a light sensor in the corridor and an ambient light sensor to block 7 of the complex. The corridor and street lighting system is connected to the FM discrete outputs, and the ambient light sensor in the corridor and on the street is connected to the FM analog inputs. Using block 10 “Engineering software”, a control program is developed based on the proposed algorithm for the functioning of the corridor and street lighting of the mansion. The algorithm is shown in Fig.3. Initial conditions of this algorithm: Time = 12: 00 days, all lighting is off.

The resulting control program is loaded into block 11 “System software”, located in block 6 “Main control device”, and is executed there.

As a result of the control program, when the light sensors reach certain predefined values and a predetermined time, the corridor and street lighting systems of the mansion take the necessary positions - on / off.

Block 9 “Client software” located on the operator’s “workstation”, block 8 displays the status of the processes (values of the sensor readings and the state of the lighting systems) and provides an interface for managing them (changing the shutdown time of the corridor lighting system, changing the settings of both light sensors, forced changing states of both lighting systems). Allows the operator to assign a sequence of tasks automatically performed by the system (setting timers), as well as to automatically record a log of changes in the parameters of technological processes.

Example 2

An example of the application of the AUVM TP complex in the industry is conveyor selection of products depending on its weight.

The production task - the product (oranges) is placed on the conveyor, which must be sorted - less than a certain weight (200 g), the distribution arrow eliminates - more or equal - it passes to the collection and packaging places.

For the functioning of such a conveyor on the basis of the AUVM TP complex, it is necessary to connect a weight sensor (scales) and a distribution arrow to unit 7 “FM” of the complex. The balance is connected to the analog input of the FM, and the distribution arrow to the discrete output of the FM. Using block 10 “Engineering software”, a control program is developed based on the proposed algorithm for the operation of the conveyor.

The algorithm is shown in Fig.4.

The resulting control program is loaded into block 11 “System software”, located in block 6 “Main control device”, and is executed there.

As a result of the implementation of the control program, when products hit the scales, the distribution arrow assumes one of two positions and sorts the products.

Block 9 “Client software” located on the “workstation” of the operator, block 8 displays the status of the processes (values of the readings of the scales and the position of the distribution arrow) and provides an interface for managing them (changing the transmitting weight, forcing the position of the distribution arrow). It enables the operator to assign a sequence of tasks automatically performed by the system, as well as to automatically record a log of changes in the parameters of technological processes.

Example 3

Tasks of operational use (housing and communal services):

Turn on / off the heating system.

For the functioning of such a technological process on the basis of the AUVM TP complex, it is necessary to connect a valve, a pump, a valve, a mountain temperature sensor. water and air temperature sensor to analog / discrete inputs / outputs of unit 7 "FM" complex. The valve and valve are connected to the analog outputs of the FM, the pump to the discrete outputs of the FM and the temperature sensor mountains. water and air temperature sensor - to the analog inputs of the FM. Using block 10 “Engineering software”, a control program is developed based on the proposed algorithm for the functioning of the heating system of residential premises in the cold season.

The algorithm is shown in Fig.5. The initial conditions of this algorithm are: The heating system is off.

The resulting control program is loaded into block 11 “System software”, located in block 6 “Main control device”, and is executed there.

As a result of the implementation of the control program, guided by the control algorithm, the AUVM TP complex performs the necessary manipulations with the valve, pump and valve, depending on the readings, the mountain temperature sensor. water and temperature sensor in automatic mode.

Block 9 “Client software” located on the operator’s “workstation”, block 8 displays the status of the processes (readings of both temperature sensors and the status of the valve, pump and valve), the unit provides an interface for controlling them (on / off pump, changing the valve position and valve, changing the setting of both temperature sensors). Allows the operator to assign a sequence of tasks automatically performed by the system (setting timers), as well as to automatically record a log of changes in the parameters of technological processes.
