This does not allow to achieve reliable operation of the device. The closest in technical essence to the present invention is a device containing drive mechanisms for movable carriages, on each of which the processed dotal is fixed. The parts are transported between the electrolytic baths 6 of a certain spatial and temporal sequence. Sensors that determine the position of carts relative to given points of the technological station are located on carts. The operation of the electro-galvanic production line is carried out according to the program using the control unit D2.1. However, the failure of the readout elements or their communication circuits with the control unit may lead to a collision of the auto apparatuses to their breakdown and stopping. lines for a long time to repair; other parts undergoing galvanization due to disruption of the order of its movement in the baths; to the contamination or damage of solutions in the baths due to the ingress of one solution to another due to the violation of the order of part transfer through the baths. The purpose of the invention is to increase reliability. The goal is achieved by the fact that in the device containing the elements of reading the code of the bath number two groups of discriminative signals are introduced, two registers, the elements AND, OR NOT, the waiting multivibrator, forming a triangular triggered pulses, a comparison circuit and a counter whose output is control output of the device, the output of each element of the code readout of the bath number is connected respectively to the input of the differentiating elements of the first and second groups and to the information inputs of the first and second registers, in The outputs of the differentiating elements of the first group are connected respectively to the inputs of the first element OR., the outputs of the differentiating elements of the second group are connected respectively; with the inputs of the second element OR, the outputs of the first and second elements OR are connected respectively to the inputs of the second element OR, the output of which is connected to the control input of the trigger through the waiting multivibrator and to the first input of the element I, the information input of the first the register is connected to the first output of the trigger, the second output of which is connected to the control input of the second register, you; the strokes of the first and second registers are connected respectively to the inputs of the comparison circuit whose output is connected to To the second input of the element I and through the element NOT to the counting input of the counter, the first and second outputs of the shaper of the square reset pulses are connected respectively to the zero input of the trigger and to the first installation input of the counter, the second setting input of which is connected to the output of the element I, the outputs of the second register are informational outputs of the device. The drawing shows a diagram of the device. The device contains baths IQ, 1, ..., gsglvanoapparata, 20, 2 ,. .., sensors, rear, 3 - ,, ... 3 codes of the bath number, elements 4о, 4- |,. . , reading the code of the bath number of the group of differentiating elements, .. 6j), 6., ... 6, ISH elements waiting for the player (rator 10, forming €; or 11 rectangular reset impulses, registers t2 and 13, trigger 1 , comparison circuit 15, elemental And l6, c4eT "WK 17, element NOT 18, informational information 19 of the device, control output 20 of the device. The sensors are spaced along the entire length of the bath zones of the electrochemical device and made in the form of an equal number of alternate copiers with direct and inverse code combinations of bath order numbers, readout elements are located on the e and alternately read the forward and reverse code combination of the bath number works as follows: When the power is turned on, the shaper 11 generates signals at the outputs 18 and 19, which provide a jump to the zero of the AND trigger and the counter 17. Further proper operation of the circuit is provided when the auto operator is installed with elements kg, k, ..., ", to the position in which they read the inverse code of the bath number. When the auto operator starts moving at the moment of changing the readable code in the inverse to the forward signal from the elements i post Paet on differentiating elements. In this case, the signal drop from the level of logical zero to level, the degree of logical unit is differentiated by elements. - After the passage of the element OR 7, a pulse of positive polarity is formed at its output, which enters the input of the element OR 9. The signal difference from the level of the logical unit to the level of logical zero is differentiated by the elements "6p, ..., 6j, and after passing through the element OR 8 is transformed into a positive impulse; / voltage at the inverse output of the element OR 8, which is fed to the input of the element OR 9. At the output of the element OR 9, a positive voltage pulse is generated, the front of which is triggered by the waiting multivibrator 10. The pulse duration of the waiting multivibrator 10 is greater than the duration of the transient the processes caused by the non-uniformity of operation of the elements of the reading of the bath number code At the end of the pulse produced by the waiting multivibrator 10, the voltage drop from the level of logical zero to the level of logical unit causes writing to the trigger 1 of the voltage. The voltage drop at the direct output of the trigger 1 from the logic zero level to the logic one level permits writing to the register 12 of the direct code of the bath number. When registering power 13 in register 13, an arbitrary code is recorded, then comparison circuit 15 outputs a signal with a logic zero level, which corresponds to the inequality of the two codes applied to its inputs. After the inversion of the elements NOT 18, a single signal from its output is recorded 594 into the counter 17. The simultaneous logic level zero from the output of the comparison circuit 15 prohibits the input element AND 16 from resetting the counter 17 by a signal from the output of the standby multivibrator 10. At the outputs of the register 12 there is a direct code of the bath number, in the zone of which the auto operator is currently located. The fault signal of 20 elements of reading the code of the bath number, taken from the output of the counter 17, corresponding to the record in the counter of two pulses, has a logic level zero. Upon further movement of the auto-operator along the line at the moment of a new change of the code of the bath number from the direct to the reverse part of the device, including the elements S,, 5-cI 6, ..., ..., 6, the elements OR .. .5. and 6, 7-9 and the waiting multivibrator 10 works in the same way as described output, however, the voltage drop from the logic level zero to the level of the logical unit at the output of the waiting multivibrator 10 causes the zero to write to the trigger I. A positive voltage difference on the inverse output of the trigger T causes Writing the inverse code at the inputs of registers 12 and 13 into register 13. When the elements of the bath number code are working correctly, the outputs of the register 13 are formed using the code of the bath number. In this case, the comparison circuit 15 generates a signal of a logical unit. The unit does not write to counter 17 because the element 18 is not inverted. At the same time, the level of the logical unit from the output of the comparison circuit 15 arriving at the input of the element 16 also allows the counter to be reset by a signal from the output of the waiting multivibrator 10. In this case, the output 20 does not produced. If one or more readings of a mod fail, the bath number is direct and the inverted by register 13 does not equal the codes by the number of steps not less than two. In this case, the signal is written through the NOT IB element into the counter 17 according to the algorithm described above two times a second, and the output of the counter 17 of the corresponding record to the counter of two units appears, the level of the logical unit that initiates a malfunction of the read elements of the code of the bath number or circuits zi with control device. A known device for determining the serial numbers of galvanic automat baths does not have the property of diagnosing the good condition of the readout elements and the circuit; connections connecting them with the command device. Therefore, in the event of a failure of the read elements or; the circuits of the connection are permanently the logical zero level or the logical unit at the output of the readout element; interruption or: short circuit of communication circuits with a yutmandoapparatomT the distorted information about the position of an auto-operator in the bath zone of the galvanoapparatus is supplied to the com- mand apparatus. The presence of two or ekuibiaerb numbers on the galvano-appliance, auto-operators with joint operation areas, distorted information about the location of one of them, and a fault from the faulty device for determining the order numbers of the bathtubs of the device, can lead to a collision of the auto-levers, their breaking and stopping. a galvano apparatus for a long time to repair, to damage a part that undergoes galvanic treatment because it is placed in a bathtub with a number that does not correspond to the required technological cycle, to contamination and damage to the solutions in the baths due to disruption of the technological order of part transfer from bath into a bath, which causes the galvano-apparatus to stop or restore the solution. The use of the proposed device for determining the serial numbers of the baths of a galvano-apparatus allows one to eliminate the noted shortcomings as a result of self-diagnostics during the operation of the device of the readout elements and their communication circuits and to generate a special signal of their malfunction, which is used for operational response of the device to the secondary malfunction, for example, by turning on engines of automating. Due to the use of the device, a reduction in the operating costs of restoration is achieved. If the readout elements or the circuits connecting them to the device fail, the lines decrease the scrap rate, increase the performance of the galvanic line by reducing the recovery time after the failure of the readout elements and the circuits with the controller.
