Description

The invention relates to instrumentation and can be used to check the wiring of cabinets, cassettes, wiring harnesses and equipment, including in the manufacture of automotive, aircraft, switchgear, shipbuilding, etc. The proposed device is designed to detect breaks, short circuits and installation errors.

A device for monitoring the installation according to the certificate for PM No. 6913, IPC G01R 32/02, containing a group of contact elements for connecting the control object and installed in the housing control system, made in the form of an information processing unit that includes an interface, a central processor, a long-term memory drive, a terminal and a printing device, as well as a switch, an output sequence generator, the outputs of which are connected to the corresponding terminals of the group of contact elements, a block of level converters and a buffer inputs, the output bus of which is connected to the inputs of the switch, and the inputs are with the corresponding outputs of the block of level converters, the inputs of which are connected to the outputs of the generator of the output sequence. In this case, the information processing unit is connected via a bi-directional bus to the switch, the output bus of which is connected to the input of the output sequence generator, consisting of the output register and the transistor switch block, the inputs of which are connected to the corresponding outputs of the output register, and the outputs are the generator outputs. A known device is designed to control a predetermined object. Change or modification of the object leads to a change in the quantity, nomenclature and configuration of the contact elements through which the control object is connected and, accordingly, to a change in the housing on which the contact elements are installed. The quantity and configuration of the connections of the control object with the control system and, accordingly, the processing algorithm of the control object also change, which leads to a change in the control system and its reprogramming. Thus, the manufacture of a known device involves the design of the housing and control system for a predetermined (known) object with subsequent manufacture and does not provide for the adaptability of the device when replacing or modifying the object of control.

The disadvantages of this device include:

- low degree of unification;

- low adaptability of the device to a change in the object of control or its replacement;

- a high level of qualification of designers and the large volumes, time and costs of designing (redesigning) devices and developing (processing) software;

- a long cycle of operations from design to manufacture of the device associated with the sequential execution of all operations of the cycle and the inability to parallelize them;

- the impossibility of combining the design processes and refinement of new control objects with the manufacture of devices for monitoring the installation of new objects.

Closest to the proposed invention is a device for monitoring installation according to Russian patent No. 2208806 “Device for monitoring installation and a method for its manufacture” IPC G01R 31/02, comprising a housing, a control system and connected contact elements for connecting the monitoring object. Moreover, the control system consists of a programmable microcontroller with a built-in “self-learning” mode, a text display, a buzzer and a power supply. A text display and a buzzer are installed on the front plane of the case and connected to a programmable microcontroller located inside the case and equipped with a set of bidirectional channels.

The disadvantages of this device include the following:

- limited ability to change operating modes, to select the types (execution) of objects of control when checking several objects on one device,

- increased cost, complexity and reduced reliability due to the formation of each bidirectional channel from a pair of channels - output and input, connected in parallel,

- increased consumption of wires with large geometric dimensions of the control object.

The inventive device is aimed at expanding the functionality, increasing reliability, reducing the time and material costs for the design, manufacture, diagnosis, repair and modernization of the device when changing or modifying the object of control. To this end, an installation control device containing a control system made of a programmable microcontroller with a built-in "self-learning" mode that automatically compiles a table of channel reference states for a given monitoring object, display, buzzer, a set of bidirectional channels connected to the programmable microcontroller, and contact elements for connecting the monitoring object to bidirectional channels, an additional communication channel has been introduced, providing the ability to read external devices data / commands from the programmable microcontroller and the external device transfers data / commands to the programmable microcontroller. In addition, the control system is configured to operatively control the installation control device, for which a keyboard has been introduced. In this case, the display, buzzer, keyboard and communication channel are integrated into a programmable microcontroller, which is made in the form of a control panel. The set of bi-directional channels is made in the form of stand-alone output channel modules having built-in diagnostics of the “short circuit” status of the output channels, available for storing (reading) and processing in the programmable microcontroller, and connected to the programmable microcontroller via a serial interface, which can be implemented in various ways: on a physical line, in the radio frequency or infrared range, etc.

As a bi-directional channel, for example, an electronic output chip of Freescale Semiconductor, Inc. can be used. (Freescale Semiconductor, Inc., 6501 William Cannon Drive West, Austin, Texas 78735), in particular the MC33291L chip, which has built-in diagnostics of the “short circuit” state of the output, which allows the output channel to be used as bidirectional.

The drawing shows a structural diagram of a device for monitoring installation.

The inventive device consists of a control system made of a programmable microcontroller 1 with built-in "self-learning" mode, display 2, buzzer 3, communication channel 4, providing the ability to read external device (computer) data / commands from programmable microcontroller 1 and transmit data to an external device / commands to the programmable microcontroller 1, keyboard 5, and a set of bidirectional channels, made in the form of stand-alone modules 6 output channels with built-in diagnostics of the status of “short circuit” ”, accessible for storing and processing in the programmable microcontroller 1, and connected to the programmable microcontroller 1 via a serial interface and, through contact elements 7, with the control object 8. In this case, display 2, buzzer 3, keyboard 5 and communication channel 4 are integrated into programmable microcontroller 1, which is made in the form of a control panel.

When changing the modification of the tested control object 8, the operator selects the appropriate software using the keyboard 5 and display 2, after which it becomes possible to check the installed modification (execution) of the control objects 8, as well as diagnose the elements of the control system of the device for monitoring the installation. The communication channel 4 is controlled from the microcontroller 1 and allows you to transfer to an external device (computer) operational information about the quality of the products being tested and to combine the group of the claimed devices into a section for collecting statistical and other information.

The inventive device for monitoring installation works as follows.

Initially, a database is created for the device, for which, through contact elements 7, reference control objects of 8 various modifications are connected to the device one by one, using the keyboard 5 and display 2, the programmable microcontroller 1 is put into “self-learning” mode, during which a reference state table is created for each modification of the reference control object 8. In the "self-learning" mode for analyzing the reference control object 8 and compiling its table of reference states in turn, a first output channel of the first auxiliary module 6 in the test object 8 is energized logic zero, with all the other output channels of each auxiliary unit 6 are set to logic-one. Next, we diagnose the state of the “short circuit” of the output of all output channels of the autonomous modules 6 set to the state of the logical unit, while the state of the “short circuit” is fixed on the output channel (channels) connected through the contact element 7, the monitoring object 8 and the next contact element 7 to the output channel of the autonomous module 6, which is in a state of logical zero. The table of reference states of the control object 8 obtained as a result of these actions uniquely corresponds to its connection diagram and is stored in the memory of the programmable microcontroller 1.

Next, one of the known modifications of the control objects 8 is connected to the contact elements 7, for which a reference state table is formed in the control system in the above way, using the keyboard 5 and display 2, the programmable microcontroller 1 is put into “test” mode, and the program for creating the current table is activated states of the control object 8 and checking it for compliance with the previously obtained table of reference states of all output channels of autonomous modules 6 for this reference control object Olya 8.

To identify errors, each output channel in each stand-alone module 6 can be given a name that can be displayed on display 2. For example, for car harnesses, the name can contain the coordinates of the connector, the contact number of the connector and the color or wire number of the monitoring object 8 connected to this output the channel of the stand-alone module 6. The detected error, in addition to the text message on the display 2, can be duplicated by the buzzer signal 3 to attract the attention of the operator both at the beginning and at the end of the verification of the control object 8.

To further reduce the cost of the device, increase efficiency and optimize it for distributed control objects 8, the output channels are combined into stand-alone output channel modules, and the display 2, buzzer 3, keyboard 5 and communication channel 4 are integrated into the programmable microcontroller 1, which is made in the form of a control panel .
