Description

one

The invention relates to controllers for controlling electrical parameters of electronic circuits, including digital hybrid and semiconductor integrated circuits, controlled by control computers (UWMs) and can be used in computing technology, electronic, radio, and other industries.

Devices are known for monitoring electrical parameters of electronic circuits, comprising a switching matrix, the inputs of which are connected to the outputs of voltage sources and currents and the output of the measuring unit, the control and display unit, the outputs of which are connected to the inputs of voltage sources and currents. block and with the input of the switching matrix. The outputs of the i-indication control unit are connected to the outputs of the matching unit, the other outputs of which are connected to the inputs of the address decoder, and the inputs of which are connected to the outputs of the computing unit.

The proposed device includes a stop driver, a time interval driver, one of which is connected to one of the inputs. from the outputs of the address decoder, and the others from the shaper of the time intervals are connected via the matching unit to the inputs of the computing unit. Timer output

The third, fourth, and fifth inputs of the stop generator are connected to the outputs of the address decoder, the remaining inputs of the stop generator are connected to the inputs of the time generator. The output of the shutdown driver through the matching unit is connected to the inputs of the computing unit.

The drawing shows a block diagram of the proposed measuring station 1, controlled by the UVM 2, containing software sources 3 voltage and current, measuring device 4, switching matrix 5, two-wire communication lines 6 of the terminals of the tested electronic circuit 7 through the switching matrix with the output of any from software current sources and voltage and measuring device; control and display device 8; a matching device 9, a decoder 10 of the addresses of the measuring station, power sources 11 of the devices of the measuring station, a driver of 12 time intervals, a driver of 13 stops of the progress of the monitoring program.

During the operation of the measuring station for installing the electrical parameters of electronic circuits, a command from the controller to form a time interval, consisting of the address and information part, is sent to the matching device 9, which coordinates the control stations of the measuring station 1 with the output of the controller. From the output of the matching device, the bit address of the command is fed to the input of the decoder 10 addresses of the measuring station, from the output of which the decrypted address of the time interval formation command is fed to the imaging unit 12. The information part of the command carrying the time interval value that needs to be generated is output from the matching device 9, directly enters the shaper 12. From the shaper output, the signal delayed relative to the address of the command to form a time interval on Rem, whose value is determined by the information part of the same team, is applied to one input of the 13 stops of the implementation of a program-controlled electronic control circuitry for the operator.

A signal arrives at the second input of the imaging unit 13 stop connected to the measuring device when the parameter value measured by measuring device 4 falls outside the limits of this parameter, i.e., in the case of an unusable test (measurement).

At the third input of the imager, 13 stops from the corresponding output of the address decipher 10 receive the signal from the command address “test {“ Measurement).

The fourth and fifth inputs of the shaper 13 stops from the corresponding outputs of the address dresser 10 during the execution of the monitoring program receive signals of command addresses, and the remaining inputs of the shaper 13 stops receive the information part of the same commands issuing the current number to the measuring station test program control.

If desired, the operator manually sets the appropriate controls of the imaging unit 13 (for example, a switch) to a position that requires stopping the progress of the program or for each test (measurement), or for an unusable test (measurement), or for a certain number of a controlled electronic circuit, or for a certain test program number of the controlled electronic circuit. When the control conditions for the above conditions are reached during the execution of the control program, namely, when the third input of the imaging unit 13 received the command address signal “test (measurement), and the second, or fourth or fifth input of the imaging unit 13 will receive the corresponding unusable“ test (“ measurement), or a commoid signal "issuing the current number of the monitored electronic circuit, or a command signal issuing the current control program control code, the remaining inputs of the imaging unit 13 will be sent to these commands of the current con number number controlled electronic circuit

or the current test number of the control program, and if the number of the circuit or number of the test coincides with the number of the circuit or test pre-set by the operator, the driver 13 will prevent the output of the signal received by its operator from the driver 12 until the operator the corresponding inhibit signal will not be removed. After removing the decisive signal: the decisive signal, the shaper 13 automatically generates a signal arriving at the input of the interruption channel of the CCM. Thus, after issuing a command for forming a time interval with the control unit to the measuring station.

goes to service other measuring stations, and this measuring station in the meantime begins to produce itself a signal that is delayed relative to the command to form a temporary

interval. UVM returns to the control of this measuring station only after the next signal from it arrives at the corresponding input of the UVM interruption channel, i.e. after a time interval, the value of which is determined by the information part of the command to generate this time interval manually set by the operator using

relevant controls, until the shutdown conditions are removed.
