(54) DEVICE FOR CENTRALIZED CONTROL

And controls

The invention relates to on-line monitoring and control means and can be used, in particular, in automated systems for controlling thermal processes.

There are known selective call control devices comprising a call unit, a dynamic information input and output storage unit connected to a switch, the outputs of which are connected to the corresponding inputs of the dynamic information indicator.

In these devices, in response to a call command, the operator receives information about one technological parameter or at most one adjustable stabilization loop. In the case of a fragmentary (overview) control, in response to a call command, a whole information array is presented at once, containing information about several technological parameters of the same type or of different types. Despite the fact that the operator can firmly know the entire sequence of necessary operations and switching operations, he spends quite a lot of time and energy on their execution. In addition, for some time it takes him to check and control the operations performed.

The purpose of the invention is to increase the efficiency of monitoring and control.

This is achieved by introducing a control unit and a group switch into the device, where the outputs of the control unit are connected to the switch and actuator inputs through the group switch, the control inputs of the static and dynamic information switches and the group switch are interconnected and connected to the output of the call block.

The drawing shows a block diagram of the device.

It contains a static information indicator 1, such as an optical projector, into which a slide with a table image, a dynamic information indicator 2, such as logic and digital indicators, a control unit 3, such as two-way buttons, toggle switches, switches, i.e. controls the stabilization circuit mode and the position of the actuators, the signaling board 4 (signals a breakdown on certain parts of the technological process), a call block 5, for example, a button lamp, a switch Op 6 static information, such as a slide mechanism for the search, the dynamic information switch 7, a switch group 8, 9 Block storing static information (e.g., the cartridge slides) unit 10 storing dynamic information.

for example, a memory of an information subsystem that removes information from sensors, switches 11, actuators 12.

Group switch 8 is designed to connect control unit 3 to a selected group of actuators 12 and switches 11 related to this fragment (to this section of the process).

The device for centralized monitoring and control works as follows.

When a disorder occurs in this area of the technological process, the corresponding board 4 lights up, the operator presses the key and thereby forms the appropriate command that goes simultaneously to the switches 6, 7, 8, forcing them to select the information and control channels that relate to this part of the process.

The entire information array is formed in advance in such a way that it includes all the necessary information and control channels related to this technological section, so that no longer is required. additional call type switchings.

The static information switch 6 locates, in the static information storage unit 9, the necessary fragment with static information relating to this part of the process, transmits to the indicator 1, spatially and structurally combined with the indicator 2 and the control unit 3. Switch 7 connects a set of indicators located in the indicator 2 of dynamic information, group switch 8 - a set of controls in block 3 to a selected subset of switches 11. and actuators 12, exactly corresponding to a given fragment.

As a result, as a result of giving out a single call command (pressing the button-button), the operator gets the sensorimotor field necessary and sufficient to control and control the selected part of the technological process, without turning off more to perform auxiliary operations like a call.

The sequence of the operator’s actions when working with such a device will be analyzed using an example when a deviation exceeding the established norms appeared in a certain area in the static information indicator. On the board of the generalized signaling disorder by sections of the technological process, the operator sees a generalized signal “disorder in section 2. The operator presses the corresponding key on the fragment call block 5, which lights up, indicating that the operator command has been received. Switch 6 searches for the corresponding conditionally constant fragment and reproduces it in the indicator 1 of static information. Switch 7 connects the indicators and the corresponding actuator to those signals or memory cells that relate to the selected area. The group switch 8 connects the button-buttons of the automatic and remote control unit 3 to the following switches that relate to this section, the "More or less" buttons by the same switch 8 are connected to the actuators, which also belong to the selected section.

As a result, a picture appears in front of the operator corresponding to the indicated state.

To switch to automatic control mode of unit 3, automatic control is enough for him to press the lamp button, in this mode, the more or less button controls the nominal value of the controller.

The type and number of indicators and controls located adjacent to the indicator of the static portion of the fragment can vary widely. The overall structure of the entire device is preserved, however, the intended purpose can change significantly.
