the vertical outputs of the information distribution unit, the fifth input of which is connected to the output of the “I.

The drawing shows a block diagram of a device for automatic control of electrical and temporal parameters.

The scheme contains the control object 1, the program entry block 2 from the punched tape or the operator in the manual control mode, the address information and working information decoding unit 3, the control unit 4, the perforator 5 activated for recording information entered into the control device on the punched tape, block 6 of the elements that turns off block circuit inputs

15 from the decryption unit, information distribution unit 7, which distributes information into blocks according to incoming addresses or commands of the control unit, measurement unit 8, performing quantitative measurement and qualitative assessment of electrical and time parameters, protection unit 9, protecting power sources, circuits switchboard and object 1sontrol from current overloads, unit 10 normalization and

25 electrical effects, which bring the parameters of electrical effects to the desired value, the switching unit 11, which creates the necessary connections between the object of control,

30 by the normalization and electrical effects unit and the measurement unit, the reset unit 12, which sets all or individual block elements to their initial state, the generator unit 13 and stimulus sources, the defect search unit 14, which localizes faults in the test object, the time reference unit 15 generating on the information screen the time delay for the operator and the start signal

0 for a measurement unit when monitoring push switch elements in a control object, block 16 for collecting and outputting information, outputting information at monitoring to an information screen and printing, a frame counter 17.

The device can operate in three modes: manual, semi-automatic and automatic. The control program of object 1 is inputted by the program entry block to the decryption block when the control signal is received from the control block. From the output of the decryption unit, full information is supplied to the perforator 5 (which is turned on by the operator in manual mode in order to obtain punched tape with the monitoring program), the address information is fed to the AND block and the information distribution block, for control purposes, part of the address information goes to block 4.

0 According to the address information, block 7 distributes the working information into blocks 8-12. In block 8 of measurements, the adjustment is made to measure the required parameter, to form the required shutter speed.

5 times between the stimulus loading and the metering, setting the tolerance rating scheme. In block 9 of protection, high-speed protection circuits are adjusted to a predetermined threshold for current overloads, ensuring protection of the sources of the generator block and sources of stimulating effects, the switching circuits of the block 11 and the control object. When an unprogrammed current consumption occurs during the monitoring process, the defined protection circuit of unit 9 will work and disconnect this type of voltage from the control object. The protection circuit returns to the ready state by a signal from the control unit 4 when the control program receives commands to install the switching circuits of the switching unit to the initial state.

In block 10, when information is received from block 7, the parameters of electrical actions are brought to the desired value. After entering the information in blocks 8, 9, 10, signals are generated that arrive at the block of elements “AND 6” and block the access of information to the customized block schemes. The switching unit and the resetting unit receive information from the decryption unit, by block unit 6 & 6. The reset unit, upon a command from the program, sets all or some elements of blocks 8, 9, 10 to the initial state. Its task is also to reset all or separately taken switching unit targets, which connects the test object with blocks 8 and 10. In the mode of on-line control of cable products for circuit integrity, insulation resistance or insulation strength, the function of the reset unit is performed The control unit 4, which, after the successful outcome of the measurement, acts on the unit 11 and starts the program input unit.

If the control unit receives from the measurement unit the signal "More (at the integrity check of the circuits) or" Less (When checking the insulation resistance or insulation strength), it activates the defect detection unit, disconnects alternately the beginning or end of the circuit (at the control the integrity of the circuits) from the measurement unit and generates signals "Yes or" No for unit 14. By switching all input points of the test object to the housing (except for the point to which the beginning or end of the peep is connected), the defect finder 14 immediately determines whether There is an open circuit or entanglement. Separation of the beginning or end of the circuit from the case is carried out by the individual reset circuit of the high-voltage cells of the switching unit, which is included in the reset unit according to the information received from the decryption unit. In the event of a break, the address of the monitored circuit is immediately printed, when entangled, the search is performed according to the principle of finding links in the "arrays of the switching unit. At the end of the switching "array

In block 11, the defect finder sends a signal to the control unit, which initiates the measurement block to measure the circuit parameter. After several transitions by descending “arrays, the search goes to the level of“ units. In this case, the switching of the arrays is stopped, information about the selectable chains comes from the register of block 14 to block 7 and further to the search channel of the switching block. When a connection is found, the address of the beginning and end of the circuit is printed. If the values of the addresses of the beginning and end of the circuit coincide (which would lead to the measurement of the internal communication between the channels

switching unit 1) unit 14 passes them without sending a measurement signal to the control unit, USING the information on the beginning and end of the circuit from the information distribution unit.

When monitoring push-button switching elements located on the control object, a time reference block is used, to which the command is sent from the decryption unit, to remove the reset reset

counters, and from the control unit (from the operator) - the command “Start. Information on the exposure time before the start of the measurement is sent to the information screen of the data collection and output unit, and the end signal

Exposure - on the unit of measurement to perform the measurement.

The unit for collecting and displaying information on the command from the control unit provides output to the information screen and print

information from the frame counter (registering the control process and controlled by the control unit), information from the decryption unit, information from the outputs of the blocks 8, 9, 10 and the inputs of the blocks 11, 12.

In addition, block 16 receives information signaling the emergency conditions of some units and units of the device.

The presence of a perforator in the automatic control device for electrical and temporal parameters expands the functionality of the device as a whole. If necessary, including a perforator during manual operation of the device in parallel

with the control, get a control program on a punched tape directly from the circuit of the controlled product.

The reset unit greatly increases the flexibility of the device. Functional blocks n

elements of the control object's scheme acquire autonomy by resetting. The reset can be carried out in various combinations, and the control can be conducted with a breakdown of parameters into groups, which facilitates control, programming and reduces the time of control.

The protection unit clears the programming possibilities, protects the switching values and elements of the control object from being out of order, performs the function of a control element.

The defect finding block uses the information from the decryption block, samples the arrays, and allows you to optimally construct the search for assembly defects in time.

The block of time counting increases the convenience of controlling the pressure elements in the control object. Control can be carried out by one operator at a considerable distance from the object of control.

The presence of the block of elements “And in the device for automatic control of electrical and temporal parameters eliminates the possibility of repeated information entering into the worked out block diagrams, which occurred when working in manual mode or while monitoring but unworked programs and which is highly undesirable. The presence of direct communication between the functional blocks and the block for collecting and outputting information allows an online monitor to monitor the state and health of the blocks and information channels of the device.
