Description

The invention relates to information output and recording devices and can be used in various automation devices, multichannel systems for measuring and controlling various process parameters (for example, monitoring and controlling rubber temperature, etc.) and other devices for outputting and recording information. A device is known for recording xdated information received from digital measuring instruments using electrically controlled digital typing machines or tape punchers containing a memory register, a code converter, a bit amplifier and a control unit 1} A memory containing a memory register, a code converter, power ratios, a decoder and C2 controls. A disadvantage of the known devices when operating as part of multi-channel digital information-measuring systems is that the output and registration of information is performed over a period of time of the connected channel. Consequently, the switching frequency of the switch channels is limited. So, when using known devices with an electronically controlled EUM-23 typewriter in multichannel systems, the channel switching frequency is not npeBbtJaeT 1 Hz when registering five print bits. In the case of information output from multichannel control systems, where the cycle time for polling channels should not exceed a specified value, their application imposes restrictions on the number of channels (control objects /). Consequently, the known devices are tial-producing. The purpose of the invention is to expand the field of application of the device by providing the ability to display information from multi-channel systems, regardless of the speed of channel switching. This goal is achieved in that the device for outputting an infocation, containing serially connected memory register, code converter, amplifier and decoder, the output of which is the output of the device, and the control unit of the first, second and third outputs of which are connected to the inputs of the register peeti, code converter and amplifier, respectively, the second input of the memory register, the first and second inputs of the control unit, the first and the third inputs of the device, respectively, the counter and the unit matched and, the first input of which is the fourth input unit, a second input connected to the counter output, a second output is connected to the third input unit manipulated, a fourth input coupled to schyhotsom block matcher.

The drawing shows a block diagram of a device for displaying information.

The device contains a memory register 1, a code converter 2, an amplifier 3, a control unit 4, a coincidence unit 5, a counter 6 and a decoder 7

The device works as follows.

In the initial state, the memory register 1 and the counter 6 are set to O. The device is started by an external pulse of the start of the cycle from the time signal (timer) input to the control unit 4, which generates an electrically controlled typewriter (EUM) start signal ..

When the switch's zero kangsh code arrives at the code match block 5, the latter generates a pulse with a duration equal to the time of the connected channel, which goes to control block 4. With the arrival of the impulse. The end of the measurement of the digital measuring device; the control unit generates a pulse of recording information. The information of the connected channel (zero) is written to the memory register. Then, when a sync pulse arrives in the ESM, control unit 4 generates a print resolution signal. At the command of the control unit 4, the converter 2 codes is bitwise tetrads. It supplies the information code to / amplifiers 3 bits and then to the decoder 7. The number of bits set by the converter codes is printed.

After setting state 2 of the converter to 2 codes, the latter issues a 3-bit code to the amplifier. Control unit 4 turns off the print resolution signal, causes a reset pulse for register 1 memory and a transfer pulse for the number of the registered channel to O. Then, when the switch's first channel code arrives at the block

the coincidence of the codes is made in the memory register 1 of the first channel information and its registration. After registering the information of the set number of channels, the block 5 of the codes coincides; the signal ends the registration, 5 which is fed to the control block 4, the last, Ii generates a carriage return signal and then resets all elements of the device to its original state.

f. condition. When the external pulse of the beginning of the cycle passes through a predetermined time interval, the information recording cycle is repeated.

The proposed device allows for the output of information from multichannel systems at any (due to technical characteristics) channel switching speeds and, therefore, removes restrictions imposed on the number of channels of the control system.
