Description

(54) DEVICE FOR THE CONTROL OF THE INSTALLATION CORRECTNESS OF ZHGUTSZH

one

The invention relates to a reference measurement technique and can be used to control installation. harnesses.

A device for controlling the installation of harnesses is known, comprising an impulse generator, an impulse distributor, a control unit, an OR element, connectors, and indicators 11.

The disadvantages of this device are limited functionality due to the fact that the device does not provide for the detection of a short clamp between the cores of the roll 1 roll.

Closest to the proposed device is a monitoring device, a bundle containing a recorder, a pulse generator, a pulse distributor, a display unit, comparison units, the first and second diodes, the first and second resistors, a reference harness, and indicators 2.

The disadvantages of the known devices are low speed and low reliability.

The low speed is due to the need for visual inspection to detect short circuits and open circuits as indicated by the indicators, and low reliability is due to the presence of a large number of second diodes and second resistors, the number of which is equal to

10 lived in a controlled harness.

The purpose of the invention is to increase the reliability and speed of the device.

The goal is achieved by the fact that a device for controlling right-sided mounting of harnesses containing a pulse distributor connected by a first output to an input of a display unit, an input through a generator of pulses — to an output of a recorder, each of the second outputs through a diode and a controlled cable to a first input the first and second elements OR, the first and second indicators, the input of the first indicator connected to the first terminal of the first terminal and the first terminal of the resistor connected by the second terminal to the device ground bus. the recorder and the output of the first OR element, the input of the second indicator is connected to the second input of the recorder and the output of the second OR element connected to the first outputs of the corresponding comparison blocks, the second outputs of which are connected to the corresponding inputs of the first OR element, and the second inputs to the corresponding outputs current outputs of the pulse distributor. The drawing shows the scheme of the proposed arrangement. The device for controlling the correctness of mounting the harnesses contains a recorder 1 generator 2 pulses, a pulse distributor, blocks 4 of comparison, connectors 5 and 6 for connecting a controlled harness 7, the first 8 and second 9 elements OR, the second 10, the third 11 sensors, display 12, the first 13, the second 14 and the third 15 elements AND-NOT, the resistor 16, the diode 17. The operation works as follows. On svgnapu from regkutyratsf 1 begins to work the generator 2 pulses. At the outputs of the distributor 3 pulses, the control signals alternately appear, which are fed to the second inputs of the comparison units 4. When the kepi of the harness 7 is not lost, the control signal from the recorder 1 through the diode 17 and the controlled harness 7 passes through the first input of the block 4, with this failure signal at the outputs of the block 4 is absent. For each sledza / sluggish clock pulse, the distributor 3 proceeds to check the following circuit. If the tested circuit 7 is interrupted, then the control signal to the first input of the block 4 does not pass and the low level set by the resistor 16 is set on it. At the same time, the output ale. 14 on the Wits signal, the element 8 enters the input of the recorder 1 and stops further testing. On the indicator 1O and with the block 12, a break signal and a yomar of the defective circuit are displayed, respectively. If the verifiable target of the harness 7 has a short circuit with another circuit, then the second input of block 4, corresponding to the second circuit, is set low, and the first input has a high level. At the output of element 15, a signal appears, which through element 9 enters recorder 1 and stops further testing. At the same time, on the indicator 11 and with the block 12, the signal of the circuit closure and the number of the defective circuit are indiindated, respectively. If the circuit being tested is confused with another circuit, a break and short circuit signal from the indicators 1O and 11 will appear at the same time, which indicate that the circuits are entangled. Thus, the connection of the first inputs of the blocks 4 directly to the anodes of the diodes 17, and not through an additional diode, as in the known device, allows to exclude from the circuit of the device a large number of elements - diodes and resistors, which increases its reliability. The introduction of elements S1I 8 and 9 and indicators 1O and 11 allows automatic detection of the presence of short circuits and breaks in the strands of the bundle 7,; which increases the speed of the device. The invention of the Device for checking the correctness of mounting of harnesses, contains a pulse distributor connected by a first output with an input of the display unit, an input through a pulse generator — with an output register curtain, each of the second outputs through a diode and a controlled harness with the first input of the comparison unit and the first output of a resistor connected by a second output to the device ground bus, characterized in that, in order to improve the speed and reliability of the device, the first and second elements OR, the first and second indicators, the input of the first indicator connected to the first input of the recorder and the output of the first OR element, the input of the second indicator connected to the second input of the recorder and the output of the second OR element connected to the first outputs of the corresponding comparison blocks, the second outputs of which are connected to the corresponding 5917138 inputs of the first element OR, and the second inputs - with the corresponding outputs of the pulse distributor.
