RU1794772C - Device for representing information in centralized traffic control - Google Patents

Description

if signals coincide on one of the coordinates of AG and AB, the information is recorded in the Corresponding ISO 5 or SIP b.

The control unit 2, through the encoder 4 on the AG bus, generates a pulsed clock signal, which through the address decoder 10 in ISO 5 or INP 6 is supplied to the synchronization input of the shift register, and at the same time, information is recorded from the output of the first information register 3 through the data decoder. and shift register 12

The recorded information in the shift registers 12 is displayed on the single indicators 13 in ISO 5 and on the digital indicators 14 in the SIP 6 and can be stored for an unlimited time.

Modern bulletin boards in dispatching information systems have a large amount of displayed objects and train numbers.

Therefore, if no measures are taken, the information during sequential input and output will flash on the display, which is unacceptable for operational personnel. For this, information from the first information register 3 at the command of control unit 2

is overwritten into the second information register 8. After that, the current information is compared in the block of comparison 9 with the previous information. If the comparison unit 9 has generated a signal that the information has been updated (inequality signal), then permission is given through the encoder 4 to record information at the corresponding ISO 5 and TIN 6 address.

To ensure that the information does not hang

unlimited time, if, for example, the communication channel from the data center to the device is damaged, the information availability control unit 7 is used, which, if no information is detected, generates a zeroing (reset) signal, which through the control unit 2 acts on the first information register and further. extinguishes all ISO and IPP.

Formula and Gain

A device for displaying information in a centralized control room, comprising: an address code generator for the display unit, the input of which is connected to one of the outputs of the decoder, the input of which is connected to the output of the receiver, and the other output is connected to the input of the register, and display units, each of which has a second register, a coincidence element and an indicator associated with the second register, one of the inputs of which is connected to the output of the coincidence element, characterized in that, in order to increase reliability, it is equipped with a control unit information, a comparison unit and an additional register, and the address code generator of the display unit is configured with a lock input, a decoder with a reset input, each display unit is provided with an additional matching element, moreover

the second register is configured to

serial input and parallel

output, while the outputs of the second register

connected to the indicator, and the second input to

the output of the additional matching element, the first input of which forms the first input of the block, and the first and second inputs of the first and second input of the matching element form the second inputs of the block connected to the corresponding outputs of the code generator of the address of the display unit, the blocking input of which is connected to the output of the comparison unit, one of the inputs of which are connected to the first output of the first register connected to the first inputs of the display units and the input of the information availability control unit, the output of which is connected to the reset input wasp decoder, the third output connected to the first input of the third register, the second

whose input is connected to the second output of the first register.
