Description

The invention relates to automation and computing, and is intended to enter information from automatic readers made of magnetically controlled contacts.

The purpose of the invention is to simplify the device by reducing the number of connections between its units.

The drawing shows the functional diagram of the device.

The device contains a group of switching elements 1, a pulse generator 2, a driver 3, switch k, counter 5, register b, indicator 7, load element 8, first 9 and second 10 triggers, element 11 EXCLUSIVE OR.

The switching element of group 1 contains the third trigger 12, the contact group of the reed switch 13, the winding of the reed switch k, the first 15 and the second 16 elements of one-sided conductivity.

The device works as follows.

When the power is turned on, the pulse generator 2 starts operating. The period of the pulses is chosen so as to ensure that all reed switches of the switching elements operate. At the same time, at the output of the imaging unit 3, a logic zero level is set, the operation time of which must ensure that the operation is set to zero and the operation is blocked

device blocks before installation in the initial state of all switching elements of group 1.

At the transfer output of the counter 5, the level of the logical unit is set, at the output of the trigger 10, the level of the logic zero, at the outputs of the register b - zeros, on the indicator 7 zeroes will also be displayed

Logic unit levels are recorded in each of the triggers 12 switching elements of group 1. This is done by organizing the triggers 12 switching elements into a kind of shift register, the elements of which are spaced along a long line o

The switch 5 is set in such a position when at its output there is a logical zero level.

Let us take this state of the device element outputs as the initial one.

After a predetermined time, the output of the imaging unit 3 establishes the level of the logical unit, as a result of which the transfer output of the counter 5 establishes the logic zero level while maintaining the initial state of the outputs. With the arrival of the pulse front from the direct output, the pulse generator 2 outputs of the counter 5 are set to the state providing the division factor equal to (M + 1), where M is the number of switching elements of the 1st group.

To consider the further operation of the device, we assume that the counter 5 is operating in the subtraction mode. After the appearance of a logical unit at the installation input of the counter with the arrival of the pulse at its clock input, its state will change to M, i.e. it will be equal to the number of switching elements in the line. At the same time, the logical zero level from the transfer of the counter 5 is recorded in the trigger 12 of the nearest switching element. In this case, it will be a switching element with number M. The next pulse of counter 5 will decrease its state by one, the code (M-1) will be set at the outputs of the counter, and the output of the nearest switching element 1 of group M will overwrite the logical zero

c in the same trigger element of group 1 with the number (M-1) and so on. Thus, the number code on the counter 5 corresponds to the number of the switching element of group 1, in which the logical zero level is set.

At sticking of the contacts of the hermetic Q of a new relay of any of the switching elements of group 1 at the time of the occurrence of the level of logical zero at the output of its trigger 12 on the information bus of the device

15 in Wits logical level zero. This will result in the output of element 11 also being set to a logic zero level. With the arrival of a pulse from the inverse output

20 pulse generator 2 at the output of flip-flop 9 sets the level of the logical unit, and the voltage drop at the output of flip-flop 9 records the state

25 outputs of counter 5 to register 6 and further display of this information on the 7 ° indicator. In this case, the number displayed by indicator 7 determines the number of the nearest switching element of group 1, in which the reed contacts are detected, and signals the need for repair .

After the completion of the cycle of operation of the counter 5, the logical zero level is set at its transfer output, which is performed by

40 installation of the trigger 9 in the initial state of

If there are no switching elements with stuck contacts in the line, then register 6 will remain in the original

45, and on display 7, zeros will be displayed. However, this still does not indicate the health of switching elements. It is possible that the relay contacts do not close at all.

50 under the action of a magnetic field or a trigger 12 of the corresponding element 1, etc. is faulty. To control the fault, it is necessary to set the level of the logical unit at the output of the switch k. However, at the output of the trigger 10, the level of the logical unit will be established only after the completion of the cycle of operation of the counter 5 by the front of the signal at the output

transfer. Simultaneously on the way out. trigger 12 nearest switch. The first element of group 1 is set to logic level zero. The level of the logical unit from the output of the treyg - Gera 10 enters the corresponding bus on. winding relay reed switch 1 switching element. A current flows through the winding of relay I, creating a magnetic field. If the relay and contact group 13 are intact, then a logic zero level will be set at the information output of the switching element. A unit will be set at the output of element 11, so that the logical zero level will be maintained at the output

With the next impulse on the forward;:: generator 2 output, the logic zero level will be overwritten into trigger 12 of the next switching element of group 1. At the same time, the output of the trigger 12 of the previous switching element sets the level of the logical unit, the element of one-sided conduction 15 is closed, the current in the winding of the relay 14 ceases to flow, the contacts of the relay 13 open, however, in the switching element

If the contacts of the relay 13 are not shorted., They show that it is possible because of a lack of right-handedness or because of the lack of
