PL100152B1 - SYSTEM FOR REMOTE TRANSMISSION OF VISUAL INFORMATION, ESPECIALLY OF DIGITAL LIGHT SIGNS - Google Patents

Description

The invention relates to a remote system providing visual information, especially digital illuminated signs, mainly when turned on cargo of building materials, intended for transferring the selected Czech to the synoptic board information placed in the memorial group dim.

Systems for transmitting information in series are known head in a bar not suitable for the immediate observation. Similar technical solution of the system for remote transmission of information has been connected data in the Polish patent description P 172044. System this one consists of a transmitting electric block transmission lines and receiving block equipment light boards with signaling elements light in the form of digital indicators.

The send block includes the table selection unit and position connected to the first entry of the band gating of the record whose output is connected with control screen via control memory na, read gating and decoder. Second the input of the read gating unit is field combined with the multiplexing unit. The band broadcast element symbols through the encoder are fields connected to the second write gating input, which The rego output is linked to the control screen through the control memory, the gating unit od reading and decoder. Component symbol broadcasting unit the encoder is also connected to the bus gim with a write gating input and through translator in the receiving block with the first input team for choosing items on the blackboard. Second the input of this unit is connected to the switch-off unit boron array and item, while the output via working memory unit and impedance unit by cha is connected to the band lem of light arrays.

The inconvenience of this system is a lot of memory necessary for information storage at the light boards of the receiving block, no depending on the control memory in the transmit block what contributes to reducing health water of the whole system. Another disadvantage of the knee there is a lack of continuous control of the working memory more, which can lead to a divergence between working and control memory.

System for the transmission of visual information, especially digital luminous signs according to the invention the bed contains a memory unit connected by by a unit multiplexing with selector input channels and with a control screen. However, the output the cut of the channel selector is connected via de¬ tektor and amplifier with a set of indicators which is linked to the beat synchroniser from which input is a combined clock generator, at what the clock frequency is adapted to set of pointers parameters.

The advantage of the system according to the invention is simplification no and reliability improvements over the the current layout, because there is no 100 152 100 152 3 additional memory chip at the remote pointers reading and reduced by se channel lector number of remotely displayed information in comparison with the amount stored and read displayed on the control screen.

Accordingly, a significant reduction is achieved not the amount of wires, which is beneficial, especially at greater distances of information transmission mation.

The subject of the invention is illustrated in, for example, the execution class shown in the drawing, which shows a circuit for remote digital transmission frontal light signs.

Between memory unit 1 and the screen on the control 2 multiple splitter is engaged- ksujacy 3 connected to the clock generator 4 so that the outputs of the multiplexing splitter 3 in the form of four channels, eight wires each information lines are bi-signal lines the number of which is the quotient of the total quantity ci bits of memory unit 1 by the number of outputs of the clock generator 4. Each switch wire are sung in series after sixteen binary pulses 2 ms duration repeated then all the time remote forward information. These outputs are linked to the screen control 2 and the remote forwarding line information, the groups of several wires standing new transmission channels. These channels are included to the information inputs of the channel selector 5, which the gated input is connected to the 6. At the outputs of the channel selector 5 vehicles sequences of binary signals selected are twisting to the channel, where the setpoint device 6 determines the way of boron of one channel on a permanent or cyclical basis wounding one channel for a certain period of time several up to several seconds.

The channel selector 5 outputs are connected to the channel with the controls of the indicator unit 7 via detector 8 and amplifier 9. Anodes of these indicators are linked to the synchronizer outputs yes here 10, feeding them with impulses lasting around 2 ms synchronized with the transmitted signal binary files with a clock generator 4, which is simultaneously connected to the branch with a multiplexing unit 3 and a synchronizer clock 10, the clock synchronizer being connected to one power supply output 11, and the amp The switch 9 is connected to the second power outlet time 11.
