(54) DEVICE FOR INSTALLATION CONTROL

one

The invention relates to the field of automation and computing.

The device can be used, for example, in enterprises making computers, sophisticated electronic equipment for testing electrical installations with a large number of controlled points.

A device for controlling installation 1 is known, which performs a check according to a predetermined program. The disadvantage of this device is the considerable complexity of the equipment and verification program.

The closest in technical essence and circuit design of the invention is a device for controlling installation 2}, comprising a comparison unit, a program input unit, a control unit and a print output unit, wherein the output of the program input unit is connected to the input of the comparison unit, the outputs of the control unit are connected with entrances

(the comparison block and the program input block, and the control block outputs - with in: the codes of the print output and comparison block). In addition, the device contains a match block, random access memory, a block of minimum distances, a block of matching arrays and an address register, whose inputs are connected to the outputs of the control unit, a second address register, whose input is connected to the output of the matching block, and a galvanic coupler, whose inputs are connected to the outputs of the address registers, and the output is connected to ku control. Such a device is also characterized by complexity of the equipment and program verification are resulting in greater cost and its relatively low reliability.

The purpose of the invention is to reduce the amount of equipment and, therefore, simplify the device.

Claims (2)

This is achieved by the fact that the device for controlling the installation, containing a source of voltage and a control unit connected to the unit) test results directly and through the program input unit with the unit, the switchboard, the first and second elements, and the first and second elements are entered. "I view the inputs of which are connected to the corresponding outputs of the input unit of the program, the second permits - to the same inputs of the first And elements and to the corresponding outputs of the comparison block, with the outputs of the first and second elements And h They are written with: one input of the switch, the other input of which is connected to the source output voltage, and the output through valve blocks to the other inputs of the first elements I. The drawing shows the structure of the device containing the control block 1, block 2 of program input, block Comparison 3, block 4 of the output of the counterblock, switch 5, control object 6 with connectors 7, elements 8 and 9, voltage source 1O, blocks 11 of the valves 12. The device works as follows. Alternately, the contacts of the connectors 7 of the object 6 are energized by positive voltage excitation from the source 1O. With efoM.Ha, those inputs of block 3, which correspond to the connectors of the existing connection with the considered clock, a positive voltage appears. Simultaneously from block 2 to block 3, a 6-pin 1 h 5 a true code (where P is the number of connectors 7 in object 6 ) containing information about the connections of this contact with other connectors of the object. The bit numbers in the codes correspond to the slot numbers and are defined as follows. The bit number corresponding to the connector in which the contact is located is always indicated by a unit (positive for example), any other I and code bit is one if there is a SfiSTli aicfidHi 1 ma and an I-th object difference between link, otherwise zero. Let I - and KOHtaKt of the first connector on f Abliyo Shytazh dOSh {1e1a connect with m contact of the second connector. When installing the object 6, the following cases are possible. The t and pin of the first connector is connected to the –m KOHTStCTOM Bixjjpoiromerem. The codes read from the outputs of block 2 and coming from the subject 6 coincide and the control unit 1 generates a permission signal that the switch 5 of the exciting voltage + E connects to the 1+ 1th pin of the first connector. L - and the contact of the first connector is not connected with any contact of the second connector. Then the second bit of the code, coming from the object, is equal to zero, and the unit signal appears at the corresponding output of the comparison block 3. In this case, the output of one of the elements And 9 appears signal no connection. The control unit 1 blocks the input of the switching resolution by the switch 5 of the exciting voltage + E, cinla, and also generates the coordinate signals (connector number and contact number) of the missing link and the type of malfunctions. When the output of the coordinates and the type of faults is completed by the block 4, the control unit releases the switching voltage of the excitation voltage. I - and the pin of the first connector is connected to any 1 contact of any m? 2o (ITljifc 2,) connector, which should not be connected according to the mounting table. Then (71 - the code bit coming from object b, and the 3 rd run of the comparison block are equal to one, at the output of one of the elements of AND 8 a signal of extra communication appears. Then a process similar to the one described above occurs. I - and the contact of the first connector is connected to the K- (P contact (F) of the second connector. Such a failure is detected when checking the second connector as faults are extra communication (when checking the K-th contact) and there is no connection (when checking the i-th contact ). The described device for controlling the installation of software compared with the known has a large simple structure. Eliminating random access memory and other blocks reduces its cost. Using such a device reduces the amount of preparatory work associated with drawing up testing programs. Invention device A device for controlling an installation containing a voltage source and A control block connected to the block of results of the control directly and through the block of program input with the block compared to, distinguishes it from the fact that, in order to simplify the mouth | Properties, it additionally contains a switch, valve blocks, the first and second AND, the first inputs of which are connected to the corresponding outputs of the program input block, the second inputs - with the same inputs of the first And elements and the corresponding outputs of the comparison block, while the outputs of the first and second elements AND through the control unit they are connected to one input of the switch, the other input of which is connected to the output of the voltage source, and the output through the valve blocks to the other inputs of the first I elements.
