Description

The technical solution relates to electrical engineering, in particular, to indicator devices for displaying information, and can find application in distribution cabinets of switchgear cells of 0.6-10 kV for monitoring the status of power circuits of the cabinet.

Known display devices [1], mounted on a switch that has a common clamp, a normally open clamp and a normally closed clamp, has an insulation board on which a common plate clamp, a normally open plate clamp, a normally closed plate clamp, connecting wires and an indicator lamp are mounted . The lamp provides an indication of disconnection between the terminals.

The disadvantage of this device is its limited functionality, as a result of which sufficient reliability and information content of the indication are not provided.

Closest to the claimed solution is an indicator device for displaying information [2], containing an indicator board (BI) for displaying information and a data receiving module (CU) for receiving digital data displayed on the indicator board.

This indicator device cannot be used in distribution cabinets of switchgear cubicles 0.6-10 kV to monitor the status of power circuits of the cabinet, because limited functionality due to the inability to receive information about the status of the power circuits of the cabinet.

The essence of the technical solution lies in the fact that due to the introduction and original connection of BL, BK and BP blocks, the functionality of the inventive device has expanded, which allows to increase the accuracy of control of the control unit, as well as the logic block and display unit, as well as power circuits of the cabinet .

The technical result is achieved by the fact that in the indicator device containing an input unit (BV), a control unit (BU), one of the outputs connected to a display unit (BI), an additional logic unit (BL), a control unit (BC), a power supply ( PSU), and the first PSU output is connected through the BL to the control unit, and the BL, BU and BI outputs are connected to the control unit.

Figure 1 shows the structural diagram of the inventive device, where the following notation:

1 - indicator device;

2 - power supply unit (PSU);

3 - control unit (BU);

4 - indication unit (BI);

5 - input unit (BV);

6 - logic block (BL);

7 - control unit (BC).

The display device contains a power supply connected by output 1 to the display unit, output 2 to the control unit, which by its input is connected to the logic unit, output 1 to the control unit, output 2 to the display unit, the output of which is also connected to the control unit, the input of which is connected to the logic unit, the input of which is connected to the input unit.

The input unit may consist of several subunits and is based on the semi-automatic elements, using a half-wave rectifier and a decoupling threshold organ.

The logic block can be made on the basis of logic elements, for example, 1533 series microcircuits, or microcontrollers manufactured by the industry.

BU and BC can be performed on the basis of microcontrollers.

As a power supply, one of the standard 5 W elements was used.

The display unit is a 128 × 64 pixel liquid crystal display.

The inventive device operates as follows.

When a voltage is supplied to the input of the power supply unit, the BI unit is turned on (at the initial moment the image is absent), the control unit begins to receive signals from the base unit and displays an image depending on the received signals. When changing signals from the input unit, the logical unit converts them for the control unit, which changes the output image of the BI. If you need to change the displayed image, just change the logic of the BL. Throughout the work, the BC periodically checks the operability of the BL, BU and BI. In the event of a BL, BU failure or an unacceptable combination of signals from the BC and BL, the relevant information is displayed on the display unit, and in the event of a BI failure, the "fault" LED is lit.

The inventive display unit has passed experimental tests and is planned for use in 4 square meters. 2004 year
