Abstract

The invention relates to information display and input devices, and can be used in the design of operator consoles. The aim of the invention is to expand the scope by changing the order of change of the displayed information. The device contains counters 2 and 10, differentiating unit 9, element 11, control unit 3, matrix indicators 5, trigger 12, register-17, photoelectric converter 6. According to the signals received at the counting input of the first counter 2, the information comes in The position codes to the information inputs of the control unit from an external device are distributed at the outputs of the control unit to the corresponding matrix indicators. The device allows you to change the text on the screen and control external devices in any order. 1 il. i (L

The invention relates to information display and input devices and can be used in the design of operator consoles.

The aim of the invention is to expand the field of application of the device by changing the order of change of the displayed information.

The drawing shows a block diagram of the device.

Signals from an external device, such as a computer, to the counting INPUT 1 of the first counter 2, the outputs of which are connected to the corresponding inputs of the control unit 3, information in the form of position codes comes from the information inputs 4 of the device to the outputs of the control unit 3 and matrix indicators 5 On some of the indicators, formalized images of the controls are displayed, on other indicators - explanatory inscriptions to them. When the operator touches the sensitive element of the photovoltaic converter 6 to one of the indicators on which there is an image of the control element, the output of the converter 6 appears with fronts which coincide with some of the signals at input 1 of counter 2. Signals from output 7 of converter 6 are fed to the input 8 of the differentiating unit 9 and the input of the second counter 10, the outputs of which are connected to the inputs of the element 11, one of the inputs of which is connected to the output of the trigger 12. With the simultaneous appearance of signals from the outputs the differentiating unit 9 and the counter 10 at the two inputs of the element 11, at the third input of which there is a signal from the output of the trigger 12, at the output 13 of the element. And 11, an interrupt signal appears that goes to the input of trigger 12, which is being pushed to another state. The changed signal from the output of the trigger 12 blocks the element 11. The signal from the output 14 of the trigger 12 is fed to the control input 15 of the control unit 3 and the control output 16 of the device. The signal from output 13 stops the illumination of indicators 5 and reads the state of register 17. The signal from output 13, which arrives at the control input of register 17, is read into information outputs 18 of the console connected

The outputs of the register 17 are supplied with information from the inputs of the register 17 connected to the outputs of the counter 2, i.e. The register 17 records the status of the outputs of counter 2. Thus, from the information outputs 18 of the console to an external device, such as a computer, information is given on the indicator number, on which the image of the control or its position, for example a button or a switch, is placed fully illuminated indicator. Information about the indicator number, together with the number of the frame in which the indicated manipulations with the photoelectric converter were performed, serves as the address of the command whereby the external device (computer), using a signal from the control output 16 of the device, changes information on the information inputs 4 of the device and switches other external signals. devices. At the same time, the signal from an external device, which supplies to the reset input 19 of the device, connected to the reset inputs of the counter 2, the register 17, the counter 10 and the trigger 12, these elements of the device are reset.
