(54) DEVICE FOR ENTERING INFORMATION

The invention relates to computing and can be used in a system for selecting information.

Devices are known for collecting information from discrete sensors, comprising a comparison device, a code memory, a recording device, a device for storing changes in the state of the sensors, a device for generating the address of the sensors, a number register, an address register, and a communication device that perform the functions of entering state information. multipoint sensors 1

The disadvantage of these devices is their complexity.

The closest to this technical solution is a device for entering information containing a block, a group of triggers. Two groups of OR-41E elements, an OR element and a registration unit, the input to the cell of the memory block is for the device inputs (to: 1, h), the output for the cell of memory is connected

to the first input of the k-th element YLI-NOT of the first group, the first output of the k-th group trigger is connected to the first input of the k-th element OR-41E of the second group, the output of which is connected to the reset input of the k-th group trigger and the reset input k- that of the cell of the memory block, the second outputs of the group triggers are connected to the corresponding inputs of the OR 2 element.

The disadvantage of this device is its complexity.

The purpose of the invention is to simplify the device.

The goal is achieved by entering a cipher block into the device, the inputs of which are connected to the output; the corresponding elements are OR NOT of the second group, and the output is connected to the input of the registration block, the output of which is connected to the second inputs of the elements OR NOT, the second group K-HH of the group trigger is connected to the corresponding inputs of the elements of the second group, having the number K + 1, K-1-2, ... and (K), the output of the k-th element OR-JHE of the first group is connected to the input of the k-th trigger groups, the output of the OR element is connected to the second isodam of the IL epi- elements. -NOT first group. The drawing shows a block diagram of this device. The device contains a memory block 1, the first group of 2 elements OR-NOT, group 3 triggers, element OR 4, the second group 5 elements OR-NOT, the encoder 6, block 7 registration. The device works as follows. In the absence of input signals, the device is in the initial state and information processing is not performed. The signal received at one of the inputs of memory 1 is recorded in the memory block element corresponding to this input, as a result of which at one j ...- one of the outputs of the memory memory appears with a signal which goes to one of the the first inputs of the first group of elements OR NOT 2. Since in the group of triggers 3 all the triggers are in the initial state, the first group of elements 2 transmits the incoming signal that goes to one of the inputs of the group of triggers 3, resulting in one of the triggers changes its state to the opposite. At the same time, the signal from the second output of this trigger through the element OR 4 acts on the first group of elements OR NOT 2 and disconnects the memory block from the group of triggers 3. Triggers the trigger group (like the elements of other blocks) conditionally assign numbers from first to . Suppose that I changed the trigger state of the trigger group of trigger group 3. The signal from the second output of the trigger circuit also arrives at the jypes of the | LIN-NOT from the h group of 5, thereby locking these elements. The signal from the first output of the k-th flip-flop is fed to the first input of group 5 and acts on it to the element at the output of which a signal appears, which is transmitted to the encoder AND returns to the initial state the element of memory block 1 and The trigger group of the trigger 3. The code with the outputs of the encoder 6 is transmitted to the registration unit 7 :. At the time of registration 34, which can be different, from the output of block 7, it is fed to the second input of group .5, thereby locking all elements of this group. After the registration is completed, this signal is removed and block 7 is ready for registration with the following information. In the event that several signals simultaneously arrived at the device input and they all entered the trigger group 3, in this case, in block 7, the sensor code with a lower sequence number, then a larger one, is fixed, because the signal from the second trigger output with a smaller order number locks all subsequent elements OR NOT groups of 5 elements OR NOT. Thus, the device provides information input to the registration unit, retaining all the possibilities with a significant reduction in the amount of equipment compared with the known. When it is necessary to enter information into the computer, the sensor code is removed from the output of the encoder. About the invention The device for entering information containing a memory block, a group of triggers. Two groups of OR-H1E elements, an OR element and a registration unit, the input to the -th cell of the memory block being the input of the device (qg, 11), the output. the memory cell is connected to the first input of the k-th element OR-NN of the first group, the first output of the k-th group is connected to the first input of the k-th element OR-NOT of the second group, the output of which is connected to the input of the K-th trigger of the group and the entrance to the cd of the memory cell of the memory block, the trigger outputs of the group triggers are connected to the corresponding inputs of the OR element, characterized in that, in order to simplify the device, a cipher block is entered into the inputs of which are connected to the outputs of the corresponding elements of the second group OR NOT and output with input b The registration of the output of which is connected to the second inputs of the elements OR — NOT the second group; the second output of the k-th trigger group is connected to the corresponding inputs of the elements OR — NOT the second group, having the number Kt-f, Kt2, ... n () , the output of the k-th element OR NOT of the first group is connected to the input of the k-th group ra, the output of the element OR is connected to the second inputs of the elements OR-NOT of the first group. b в.З Sources of information, accepted understanding during the examination 1.
