Description

(54) DEVICE FOR CODING SIGNALS

one

The device relates to the field of computer engineering, to devices for encoding information and can be applied in information systems.

The coding devices 5 are known to contain a functional keyboard with mnemonic symbols of mitgs.,

In these devices, the outputs of the function keys are connected via a separation circuit to the inputs of a code formatting unit, a communication unit with a computer or a VNU, a control unit selection word for the control unit, also connected to each other by corresponding connections.

However, in practice for the description of a number. information arrays use a local dictionary with a relatively small number of: characters ,. distributed in the frame in a strictly deterministic sequence. For such frames, the use of devices with blocks of visual rendering, blocks of control words is impractical, but visual control of the frame is necessary, since logical control and information processing with errors

leads to overheads of machine time.

It is also known a device containing address control elements, transmission control elements AND command elements, registers to descramblers, which are connected to the first inputs of indicators and to the output unit.

A disadvantage of the known device is the complexity and limitations of the functionality.

. The aim of the invention is to simplify the device and expand its functionality.

This is achieved by inserting the AND, OR elements, the control unit, the clock pulse shaping unit and the switch, the outputs of the address control elements connected to the inputs of the switch, the outputs of which are connected to the inputs of the indicators and the inputs of the command controls whose outputs are connected to the inputs of the OR elements, the outputs of the OR elements are connected to the first inputs of the first AND elements and one OR element, the output of which is connected to the input of the clock shaping unit, the second input of which is connected to the output of the control unit, the outputs are connected to the second inputs of the And elements and the decoders, the outputs of the And elements are connected to the inputs of the registers, the input of the control unit is connected to the output of the output unit. The drawing shows a structural electrical circuit of the device. The proposed device contains a switch 1, address control elements 2, operator console 3, command control elements 4, indicators 5 and 6, OR elements 7, AND elements 8, OR element 9, clock pulse generation unit 10, registers 11, decoders 12 elements AND 13, output unit 14, control unit 15, transfer control element 16. The device works as follows. At the beginning of operation, the operators, each of their console 3, by pressing the address control elements 2 generate request signals arriving at the corresponding inputs of switch 1. In accordance with the priority scheme in switch 1, a next channel is selected, the output bus of which is supplied with power supplied to the elements 4 command controls, control unit 15, indicators 5 and 6 of the respective console 3. The first indicator 5 is turned on, allowing the operator to start working. By pressing one of the elements 4, the operator enters the element AND 8 through the element OR 7 and the signal opened from the first output of the clock generating unit 10, AND 8, the numerical value of the first value in the first register 11. The corresponding indicators 6 of this console 3 highlight the numerical value of the parameter. Through the element OR 9 receives a signal of testing the code to the input of block 10, preparing it for the input of the next character. Then, the following registers and sequence indicators are worked out in a similar way until the last parameter is worked out. Having visual control of the frame, the controller can correct it if necessary, then, after verifying the correct set, press the transmission control element on its console, the signal from which will go to the input of the control unit 1 to form a command to read information from the registers. From the control unit 15, a read signal is received at the input of the unit 10, from the output of which the same signal arrives at the input of the AND transmission elements, providing transmission of information to the output unit 14, from where it can be transferred to the computer. Blocks 14 and 15 provide for the exchange of information using a standard exchange interface. Then, similarly, perform the transfer of information from the subsequent registers of the sequence registers group 11. After the last clock cycle has been completed, the signal from the output of unit 10 enters bpoc 15, the latter generates a signal for the end of a given subscriber and sends it to switch 1. Here, the next subscriber is selected according to the priority scheme and a cycle similar to the one performed for him is performed. The device allows to provide the possibility of displaying data with the subsequent control of the correction.
