Description

The utility model relates to the field of telecommunications and can be used in communication, monitoring and control systems in various areas to organize sound and light indication of accidents, malfunctions or other changes in equipment operation.

Devices are known for displaying the status of the controlled equipment, for example, a factory-made device that allows you to provide a light alarm and a duplicate sound alarm, as well as a light alarm informing you about the sound alarm being turned off [TOS-5 general alarm display, electronic resource, URL: http: //www.promsd.ru/market/dopolnitelnoe-oborudovanie/tablo-obwei signalizacii-tos-5/ (date of access: 05/18/2022)], [PAS-71F alarm panel, electronic resource, URL: https: //vbrspb.ru/product/panel-avariino-predupreditelnoi-signalizacii-pas-7117 (date of access: 05/18/2022)]. The disadvantages of these devices are:

- the complexity and high cost of the design due to the construction on microprocessor technology;

the impossibility of manufacturing such devices outside specialized industrial conditions due to the complexity of manufacturing printed circuit boards and mounting microprocessors on them;

- the need for knowledge of specialized programming languages and specialized devices for programming in the manufacture of such devices;

- limited number of controlled equipment;

- inability to increase the number of controlled equipment;

- rigidly defined dimensions of the device, the inability to change the dimensions of the device for different installation locations.

The objective of the utility model is to expand the arsenal of technical means used to monitor the occurrence of accidents, malfunctions or other changes in the operation of the equipment.

The technical result consists in the implementation of the purpose - an alarm panel indicating the occurrence of accidents, malfunctions and other changes in the operation of the equipment.

The task is solved, and the technical result is achieved by an alarm panel consisting of a DC bell, two terminal blocks, two light emitting diodes to indicate the presence of power and turn off the call, two resistors to limit the voltage on the light emitting diodes and the required number of signaling units of the same type. Each signaling unit consists of a switch to turn off the call, a light emitting diode to indicate the occurrence of an alarm, a resistor to limit the voltage on the light emitting diode and a semiconductor diode to exclude the influence of one unit on others.

The electrical circuit of the device is shown in Fig. 1. The device (1) consists of a housing of the required shape and dimensions, inside which there is a DC bell (for example, 32617-00-00) (2), two terminal blocks (3, 4), a light emitting diode (for example, AL307BM) ( 5), in series with which a limiting voltage on the light emitting diode (5) resistor (6) with a nominal value of 5 kΩ is soldered, a light emitting diode (for example, AL336I) (7), in series with which a limiting voltage on the light emitting diode (7) resistor (8) with a nominal value of 5 is soldered kOhm, and the required number of signaling blocks of the same type (9).

All signaling units (9) are the same and consist of a two-pole toggle switch (for example, P2T-1-1V) (10), a light emitting diode (for example, AL307BM) (11), in series with which a limiting voltage on the light emitting diode (11) resistor is soldered ( 12) with a nominal value of 5 kOhm, a semiconductor diode (for example, KD105D) (13).

Most modern industrial equipment has relay "dry" contacts. In the event of changes in the operation of the equipment (the occurrence of accidents, malfunctions, etc.), these contacts are closed. Using the contact data, it is possible to switch the GND signal to the terminal block (3) of the device (1).

When the device (1) is connected via the terminal block (4) to the power supply network with a constant voltage of -48V, the light-emitting diode (7) "-48V" lights up. When the GND signal from Equipment 1 arrives at the device (1), a potential difference (voltage) of -48V occurs between pin 1 of the terminal block (3) and pin 1 of the terminal block (4), as a result of which the light-emitting diode (11) "Alarm 1" lights up and the DC bell is activated (2). When switching the toggle switch (10), the DC bell (2) is switched off and the light-emitting diode (5) "Toggle switch off" lights up. Semiconductor diode (13) is used to separate all signaling units. If the semiconductor diode (13) is missing and the GND signal arrives at one of the contacts of the terminal block (3), the light emitting diodes (11) on all signaling units (9) will simultaneously light up.

A photograph of the claimed device is shown in Fig. 2.
