Description

The invention relates to computing, in particular to indicator devices, and is intended to represent information in the form of letters, numbers, symbols, etc.

The purpose of the invention is to increase the reliability of the device.

Figure 1 shows the functional circuitry of the device for displaying information; figure 2 - pulse shaper.

The device contains a converter of 1 codes, a first register 2, an indicator 3, a switch 4, a pulse shaper 5, a second register 6. The pulse shaper contains a generator of 7 pulses, the first and second elements And 8 and 9, the counter 10, the first and second triggers 11 and 12, element OR 13.

The device for displaying information operates as follows.

In the functional mode of the device, the information for display on the indicator 3 is supplied to the second information and second control inputs of the switch 4 from the source of the reflected information.

The number of synchronized pulses is equal to the total number of LEDs of all familiar places of the indicator 3

The presence of a pulse at the second information input of the switch 4 and the presence of a synchronization pulse at the second control input of the switch 4 is the requirement that the LED 3 lights up, the number of which in indicator 3 is equal to the number of the synchronization pulse.

If there is an information signal at the information input of the code converter 1, the last bit of the last record is one. In the absence of a signal at the information input of the 1 code converter, zero is written to the left of the last bit. In the presence or absence of a signal at the information input of the converter 1 codes, the first digit of the last one will be written 1 or O, respectively.

The process continues similarly for the number of SI pulses equal to the number of LEDs of the first digit of the matrix indicator 3.

Upon receipt of a sync pulse for the last LED of the first familiarity, it appears

pulse overflow signal arriving at the control input of the first register.

Information for displaying on the first digit of indicator 3 from the information output of the code converter 1 is fed to the information input of the first register 2.

The information from the converter 1 of the codes is parallel to the code of the pavisode in the first register 2. Each bit of the first register 2 is connected to the corresponding LED of the first familiarity of the indicator 3, on the first familiarity of which the required information is displayed. The number of bits of the converter 1 codes and the first register 2 is equal to the number of LEDs in each familiarity of the indicator 3.

After displaying the information on the first digit of indicator 3, the code converter 1 is zeroed and ready to receive information on the second digit of indicator 3.

When the first 1 synchronization pulse codes arrive at the synchronization input of the converter 1, the unit 1 is written to the second digit of indicator 3 for the second digit of the converter 1 of the codes.

When a signal arrives at the information input of the converter of 1 code to the zero bit of the last, zero is written.

When the second synchronization pulse arrives at the synchronization input of the converter of 1 code and in the presence or absence of an information signal, the information input of the code converter 1 records the first or last digit of the last one or zero.

The process proceeds similarly for the number of synchronization pulses equal to the number of LEDs 13 of the THIRD mark of indicator 3. When the synchronization pulse for the last LED of the second familiarity arrives, a pulse overflow signal appears at the control output of the code converter 1. The signals from the outputs of the converter 1 codes are fed to the control input and the synchronization input of the first register.

At the second sign of indicator 3, the required information is displayed. After displaying information on wto

In addition to the indicator indicator 3, the converter 1 of the codes is zeroed and ready for receiving the information displayed on the third indicator of indicator 3.

The process continues sequentially and ends after the display of information on all familiar places of indicator 3.

In the self-monitoring mode, the information display device operates as follows.

The signal from the output of one of the bits of the second register 6 is fed to the first control input of the switch 4. In the second bit of the second register 6, one is recorded.

In this mode, the device is checked to display information and simulate the reception of information to display information by all the LEDs of the indicator 3.

The signal from the outputs of the bits of the second register 6 is fed to the information inputs of the pulse driver 5. From the first information input of the pulse generator, the signal arrives at the first input of the NLI element 13 and sets the second trigger 12 to a single state (Fig. 2). The signal from the output of the element OR 13 arrives at the installation input of the first trigger and sets it to one state. The signals from the outputs of the first and second triggers 11 and 12 are received at the second inputs of the first and second elements AND 8 and 9. At the first input of the first element And 8 receive impulses from the generator 7 pulses. From the output of the first element And 8, the pulses are fed to the counting input of the counter 10, the control code of the driver 5 pulses and the first input of the second element 9, from the output of which information is fed to the information output of the driver 5 pulses. Counter 10 SH-shet capacity, equal to the total number of snetodiodov all familiarity of the indicator 3.

When a pulse equal to the number of LEDs in the indicator 3 arrives at the counting input of the counter 10, the output of the counter 10 causes an overflow signal that sets the first and second triggers 11 and 12 to the zero state

Thus, at the outputs of the pulse former simultaneously form

There is a serial code of pulses. The number of pulses is equal to the number of LEDs in the indicator 3. The signals from the outputs of the im-. pulses arrive at the first control and information inputs of the switch 4.

In indicator 3, after all the information from the driver 5 has been received, all the LEDs light up.

In the View mode, the second bit of the second register 6 is zeroed, and in the first bit of this register a unit is recorded and a signal appears at the output of one of the bits of the second register 6. In this mode, the device is checked to display information by simulating the reception of information to display information 1-1 and there is no signal on all LEDs.

dakh indicator 3.

The signal from the output of the bits of the second register 6 is fed to the information inputs of the driver 5 pulses. The signal from the output of the first trigger 11 is fed to the second input of the first element And 8, to the first input of the first element And 8 post p: from the pulses from

7 И1Ч1тульсов, the signal from the output of the first element И 8 is fed to the counting input of the counter 10 and the output of the synchronizer and the driver 5 pulses. At the information output of the imaging unit 5 pulses 1, the ifrmation is absent, since the second element And 9 is closed. The overflow signal from the counter 10 is fed to the reset input of the first trigger 11 and sets it to the zero state. This trigger removes the signal from the finished input of the first element And 8. A sequential code on the counting input of the counter 10 and the information output of the forwarder 5 pulses is missing.

Thus, at the information output fog-M of the puller 5 pulses a sequence of pulses is formed, the number of which is equal to the number of LEDs of the indicator 3.

Next, the device for displaying information 1 also operates in the same way as the described operation mode in the absence of information at the second information input of the switch 4.

Thus, in the device for displaying information in the self-test mode, all elements of the signal path are checked.
