Description

The invention relates to the field of automation and computer technology and can be used to account for the operating time of a computer with the purpose of evaluating the effectiveness of its work and settlements with customers.

The aim of the invention is to expand the scope of application by providing the possibility of entering constant directives in a computer.

FIG. 1 shows a functional diagram of the device, a variant of its connection to a computer; in fig. 2 - functional diagram of the unit; in fig. 3 - functional block synchronization circuit.

The device contains (Fig. I) switch 1, converter 2 codes, counter 3, generator 4, synchronization unit 5, control unit 6, memory 7, elements OR 8, electronic clock unit 9, information input device 10 in Computer, elements OR 11, unit 12 control input to the computer ..

The control unit 6 (FIG. 2) contains a counter 13, a decoder 14, a pulse shaper 15,

The synchronization unit 5 (FIG. 3) contains an OR 16 element and a pulse shaper 17.

The device works as follows.

When the time and date input mode is activated (external start from the button), the generator 4 is started. The counter 13 of block 6 sequentially counts the pulses arriving at its input. In this case, low word sampling potentials from the permanent memory 7 appear on the corresponding outputs of the decoder 14. When the last character of the message (directive) is selected, the shaper 15 with a delay equal to the input time of the last character follows a negative difference on the n-output decoder 14 generates a short pulse that returns the entire device to its original state.

When the device has variable information (the time and date figure from the permanent memory 7 receives a signal at block 5. At this, a high potential appears at one of the inputs of the SHSh 16 element, the driver 17 generates a pulse, the positive potential of which decides converter 2 codes, and the rising edge of the pulse increases the value of counter 3. Using switch 1 from block 9, the next digit of time and date is selected, converted by converter 2 of codes, and passing through the first inputs of the OR 8 elements, a device for output and through OR elements 11 in the block 12. Next the block 12 Sun directive post ttaet in computers.

In the process of operation, the device generates the following directive: Ti DATE DTSD.GG, SOSK HH. MM (I), where DDTS, HH, MM is the variable information of this directive. The remaining eighteen characters of the directive (1) are permanent - the information of the directive is constant.

In the Time and date input mode, the constant information is transmitted to the computer from the permanent memory 7, and variable - from the information inputs of the device, for example, from the block 9 electronic clocks. In this case, from the deputirator 14 of block 6 sequential sampling pulses of constant information are received into the permanent memory 7 and pulses of variable information sampling - into block 5. IZH elements I serve to enter into the computer through the block 12 information from two directions - from unit 10, included in the computer, or from the outputs of the device.
