The drawing shows a diagram of the device.

A device for collecting data on time records includes a remote control 11 _P manual input, reading blocks 2, -2 _P> elements 3 | -3 _p comparison, blocks 4, -4 _p control reliability reading, blocks 5, -5 _P RAM, elements And 6, -6 _P , information detection unit 7, current time unit 8, code signal unit 9, switch 10, polling unit 11, health monitoring unit 12, buffer memory unit 13, parity analysis unit 14, parity comparison element 15, unit 16 information output, recorder 17.

The remote control 1, - 1 _П manual input contains buttons for dialing the cipher of the reason for the late passage through the checkpoint, memory and indication of the cipher. Reading blocks 2 | -2. contain reading cassettes, cipher dial buttons, banners! Cipher »Go, Stop, The token in the binary decimal code contains information about the shop number, personnel number of the shift, and, in addition, a sign of parity of each decimal digit of the details.

The device operates as follows,

When a token is inserted into one of the reading blocks 2 | information from the token is recorded in block 5, the RAM from the output of which goes to element 3, comparisons by buttons and to block 4! the reliability of reading, The signal for the availability of information from block 5, receives an inappropriate input of the switch 10. According to the last bit of information recorded in the block 4] of the reliability of reading from block 5, the main memory receives a permission signal to control information on parity. If the information is read correctly, then to one of the inputs of the element And

758213 6

6, by block 4, a signal is prepared for preparing a general control of the reliability of reading from this reading unit 2, and the last one receives the Control enable signal by buttons and the code number is displayed. If 5 information is incorrect, the “Cipher” banner is not displayed. In this case, it is necessary to remove the token and insert it again. How is the information rewritten in the RAM unit 5]? When highlighting the banner 10 'Ta Cipher ”, the cipher of the personnel number is dialed by pressing the buttons in the support of the divided sequence. Control by buttons allows you to get the full accuracy of registration of personnel numbers, information * ¹ 15 about which is the basis for personnel records.

When you try to select the cipher of the personnel number and press one extra button, element 3, comparisons by buttons, signals a violation and gives a signal to block 5, the RAM, by which the recorded information is erased.

With the correct set of cipher element 3, the comparison by buttons gives a signal to the second 25 input of element And 6, from the output of which the signal of the general control of the validity of reading is fed to the corresponding input of the switch 10. Switch 10 contains a ring register that gives a permission signal for rewriting 30 information from blocks 5! -5 _p of RAM through the information detection unit, to the buffer memory unit 13, as well as time interval meters between the moments of arrival of signals about the availability of information in the corresponding random access memory and the moment of arrival of readout control signals. Upon receipt of a signal for general control of the reliability of reading elements And 6, the switch 10 is installed at a temporary position 40, provides a polling permission signal to the block $ ι of RAM and a signal to start the polling unit 11, which generates a polling signal. The polling unit 11 contains a ring register, the temporary positions of which correspond to the ₄₅ decimal digits of the Token details, the code of the reason for the passage, code signals and the current time. The specified information through block 7 information detection is recorded in block 13 of the buffer memory. At the same time, according to the same polling signals, information on the parity of decimal digits and token details comes from block 5 (RAM to one of the inputs of the parity comparison element 15. From the output of block 13 of the buffer memory, the information will be paired to parity analysis block 14, from the output of which there are sign signals parity is fed to the second input of the element (even-> 5 comparison. When comparing the signals of the parity signs, the parity comparison element 15, from the output of which the signals of the parity signs are fed to the second input of the parity comparison element 15 In particular, it gives signals to one of the inputs of block 11 and the information output block 16. Based on these signals, the information output block 16 generates an information registration permission signal to the recorder 17, and the polling block 11 through the switch 10 allows information to be erased in block 5, RAM and the remote control 1 _(manual input unit and starts to poll the buffer memory. at the end of the survey information output unit 11 erases data in the block buffer memory 13 and outputs a signal "go" in the reading unit 2 _g and the switch 10 moves to the next time nnuyu position where the reading reliability of control occurs.

If the signals of parity are not compared, the polling unit 11 cyclically rewrites the information from the memory mouth. 5, to the buffer memory unit 13 until the signals are compared to the parity comparison element 15, and provides information on the number of rewriting cycles to the health monitoring unit 12, signals a device malfunction and gives a signal to the reading unit 2, according to which at the last the banner “Stop” is displayed. In this case, you need to rewrite the information in block 5, RAM in a known manner. When the length of the time interval between the moment of 'recording' information in block 5, the main memory and the moment of checking the reliability of reading in excess of poop, the health monitoring unit 12 also signals a malfunction of the device. The synchronization of the operation of the polling unit 11 and the registrar is carried out by the information output unit 16. The parity analysis unit and the information output unit 16 are structurally made in close proximity to the recorder 17 in order to control the communication channel between the main units of the device and the recorder 17.

The presence in the device of additional units 4, -4 _{p for} checking the reliability of reading elements 3ι-З _{p for} comparison by buttons allows you to control the reliability of reading information until it is registered. The presence of blocks 5 _| -5 _p and the switch 10 allows parallel reading of information from the reading blocks 2, -2 _p and registering the one that passed the control for reliability, which increases the speed of the device.

The presence of the buffer memory block 13, the parity analysis block 14 and the parity comparison element 15 allows you to control the accuracy of the information. Directly before registering it 7 758213 8 frost, to correct errors when transmitting signals by overwriting the buffer memory block 13 and control the parity comparison element 15.

The presence of a parity analysis unit 14 together with ₅ code signals device 9 allows registering, parity signs and message section codes, which are necessary for monitoring the recorder and for further use of the recorded information in a computer without additional processing.
