Description

one

The information device is in the area of devices that allow information to be obtained from the manual input sensors.

The known devices, which provide convenient representation of information in alphanumeric form, are very complex, which limits their field of application.

The aim of the invention is to simplify the device and increase its reliability.

The goal is achieved by using an encoder, a backlight and an excitation generator in addition to the usual call keys, sensors and indicators. The use of the proposed device can be considered by the example of its use in an institution as a device informing, for example, visitors about the location of an employee.

Information on the location or time of arrival of employees is displayed on the indicator line. The length of the string and the number of elements of the encoder. It may be different depending on the type of information that needs to be displayed.

The use of an information device in an institution arranges the working day of employees, significantly reduces the unproductive expenditure of working time for issuing various certificates of location and arrival time of employees, allows for monitoring the work of employees and receiving information about their location or arrival time.

The drawing shows a block diagram of the information device.

It contains sensors I, excitation generator 2, power supply unit, encoder indicators 5 call keys 5 and lamps

Highlight 7.

Sensors / are designed to enter information into the device (each employee must have their own input element). Excitation generator 2 is designed to excite electroluminescent indicators on which information is displayed.

The excitation generator provides the voltage required to power the indicators.

The power supply 3 provides power to the information device. Sensors Y, excitation generator and b. The power supplies are combined in one unit-information input unit.

The encoder 4 is designed to form a voltage at its respective outputs depending on the signals at its inputs. Indicators 5 are intended to display information. In the proposed

The device uses the sign-synthesizing mapping method.

Indicators can be applied by character-letter electroluminescent indicators, which allow displaying Arabic numerals and all letters of the Russian alphabet.

Call keys 6 are designed to call employee information on the indicators. As a call key, any self-returning buttons with one closing and one opening contact can be used. The number of call keys must be equal to the number of sensors. Call keys 6 are connected to sensors 1, illumination lamps 7 and power supply unit 3.

Lamps of illumination 7 are intended for illumination of surnames of employees. At the same time, they signal that the information device is turned on. The encoder 4, the indicators 5, the call buttons 6 and the illumination lamp 7 are combined into one block-board information device.

On the front panel there are indicators 5, information call keys 6 and the names of the employees above the buttons. The encoder 4 and the illumination lamp 7 are located inside the board.

There are various options for using the information device.

In the case when the water information console is installed in the working room of the employees, the display is in the office of the head, the head can at any time receive information on the whereabouts of his employees or on the time of their arrival. In the case when the information input console is installed in a convenient place (for example, at the exit of the institution, at the gateway, etc.), and the board at the workplace of the institution, any employee will receive information about the location of the employee he needs. If the information input console is installed in the institution (in the laboratory, in the department, in the workshop), and the board at the entrance to the institution, this option of using the information device is advisable when, under the conditions of the regime, unauthorized persons should be excluded from the institution or reduced to the limit.

The operation of the information device is as follows.

In the initial state, the information device is turned on. Institutional staff arriving at work or departing from it.

Care on business, at meetings, etc., enter information about themselves using sensors 1, i.e., set their switches to the appropriate position. Excitator 2 does not work because no power supply is applied to it. The voltage at the inputs of the screen 4 is absent, therefore, there is no voltage at the outputs of the screen, the indicators 5 are off, the call buttons 6 are in the pressed state, the backlight 7 is applied through their closed contacts. The names of all the employees are highlighted .

To obtain information about the location or time of arrival of the employee, use his call key 6 - press the button under the corresponding last name. In this case, the voltage from the backlight lamps 7

is removed and fed through a sensor / employee at one of the inputs of the tweeter 4. The encoder supplies power to the excitation generator 2. The excitation voltage of the indicators through the circuits formed by the encoder 4 is supplied to certain segments of the electroluminescent indicators. At the same time, on the row of indicators 5, the information that the employee introduced in himself is highlighted. Voltage

each input of the digitizer 4 corresponds to a certain type of text displayed on the indicators 5.

When you release the call key 6, the circuit returns to its original state - goes out

information on the indicators 5, since the voltage is removed from the input of the encoder 4 and the supply voltage from the excitation generator 2, and the last name is highlighted, because through the closed contacts the key

Call 6 is powered by the backlight lamps 7.
