Description

The inventive utility model relates to automated control systems (ASK) of electrical connections (ES), and specifically to the ASK control of electrical connections of wire and printed wiring and units containing passive electronic components in complex electronic devices.

A device for monitoring the mounting structures of electronic equipment (AS SU 1619205A1, prior. 03/11/1988. - IPC G01R 31/02), comprising a control unit, standard registers, comparison units, circuit and contact counters, information processing unit, print and output register blocks, circuit analysis blocks, signature and status fixing block.

A device for monitoring installation (Pat. RU 2344431, prior. 02.08.2005. - IPC G01R 31/00) containing a control system based on a programmable microcontroller with built-in self-learning mode, display, buzzer, a set of bidirectional channels, contact elements for connecting the control object and a communication channel that provides the ability to read data / commands from the programmable microcontroller by the external device and transmit data / commands by the external device to the programmable microcontroller.

Closest to the proposed utility model is a tester for wiring and printed circuit boards STS-1000 (Pat. RU 78952, prior. 08.24.2008. - IPC G01R 31/02), containing a control system implemented in the form of a test controller made on the basis of industrial a computer with peripheral devices necessary for the control organization, an ME-USB / RS232 expansion module with a USB / RS232 interface that provides galvanic isolation of the USB bus between the test controller and the tester, control of the measurement test modules, signal synchronization for measurement test modules and broadcast control signals for expansion modules, each measuring module comprising an interface unit, a microcontroller, a differential amplifier, an analog-to-digital converter, an input signal generation unit I, U, a signal level control unit, a voltage conditioner U = 0 V, switches of the upper and lower keys, each of which provides switching of 128 control points, a ± 24 V power supply and contact elements for connecting the control object, and ktnye elements are designed as test adapters, manufactured specifically for the tested products.

The disadvantages of the described analogues and prototype are: the need for an external power source of relatively high power, which does not allow the creation of a portable ASK ES, high weight and dimensions, the lengthy process of manually creating a separate test program for each control object (lack of modes "Export circuits" and "Auto programming" ), low reliability of control due to the lack of a complete check of all compounds according to the “each with each” method.

The objective of the claimed model is to increase the efficiency of control of electrical connections of wire and printed wiring by increasing the speed and reliability of control, as well as expanding the class of controlled objects due to the ability to control passive electronic components, including those having electrical connection with the grounding of the controlled equipment.

The increase in the speed and reliability of control of electrical connections is achieved by applying high-speed processing of test information directly in the control channel and complete verification of all connections using the “each with each” method, which minimizes the negative impact of the human factor.

The technical result is achieved due to the fact that the ASK ES is made in the form of functionally spaced blocks: a control personal electronic computer (PC) that sets the operating modes of the ASK ES and performs processing and output of the obtained control results; galvanically unconnected with a PC test information pre-processing unit, consisting of a control unit, an R / U conversion unit and N switching units, the number of which depends on the required number of controlled points, which is theoretically unlimited, and each switching unit contains M test channels, each of which is a structurally complete element and contains from 64 to 256 channels.

The inventive utility model is illustrated by the functional diagram depicted in figure 1 and containing the following functional elements: 1 - control PC; 2 - block pre-processing test information; 3 - control unit; 4 - galvanic isolation unit; 5 - block microcontroller signal processing (measurement results); 6 - N switching units; 7 - M testing channels (M = 64 ... 256); 8 - block analog-to-digital conversion (ADC); 9 - block conversion R / U; the control unit 3 is connected to the control inputs of the N switching units 6, the information inputs of which are connected to the control object, and the outputs are connected in pairs with each other and through the R / U 9 conversion unit are connected to the input of the analog-to-digital conversion unit 8, the control inputs of which are connected with a control unit 3, characterized in that an additional microcontroller high-speed signal processing unit is connected to it, connected to the control personal electronic computer via the USB2.0 interface bus.

The task and processing of the results of the ASK ES from the host PC is performed in the following modes:

- the mode “Description of the structure of contacts of connection to the controlled object”, which allows to obtain the result of verification in real addresses;

- “Autoprogramming” mode, which allows you to get a complete list of circuits using the “Photo from a reference object” method, followed by displaying the list in real addresses on the screen and / or storing it in PC memory;

- “Export circuits from P-CAD” mode, which allows you to automatically prepare a test program without a reference object, followed by displaying the list on the screen and / or storing it in PC memory;

- “Connection Check” mode (each with each) - automatically displays data on the results of the verification in the display and registration tools in the format: “No connection”, “Extra communication”, “Incorrect resistor rating”, “Incorrect diode polarity”, “Faulty” switch";

- “Real and reference circuit” mode, which allows you to selectively display and compare real circuits obtained during the “Connection Check” mode with reference circuits stored in the PC memory;

- “Self-monitoring of operability” mode, which allows for on-line diagnostics of the ASK ES and verification of the health of the connecting device.

The device operates as follows. The pre-processing unit 2 of the test information interacts with the host PC 1 via the USB2.0 interface through the galvanic isolation unit 4, which is connected to the microcontroller unit for signal processing 5, which converts the commands at the task level into the control signals of the ADC unit 8 and N of the switching units 6.

The switching units 6 consist of M channels 7 of the impact switch and the state switch, combined in pairs at the inputs through which the monitoring object is connected. The outputs of the impact switches and state switches of all M channels 7 are connected in pairs between each other. The outputs of all N switching units 6 are connected in pairs with each other and are connected to the input of the ADC 8 through the conversion unit R / U 9. The result of the conversion from the ADC 8 is fed to the input of the microcontroller signal processing unit 5, in which high-speed conversion of the test results of the test object is carried out and preliminary processing of information in accordance with the task received from the control PC 1.

The result of high-speed conversion, through galvanic isolation unit 4, is transmitted via USB2.0 interface to the control PC 1, which performs the final processing of test information simultaneously with high-speed conversion in the preliminary processing unit 2. Such a two-level distribution of test information processing tasks can significantly increase the control speed compared with analogues.

The power supply of the pre-processing unit 2 of the test information is provided from the USB2.0 bus of the control PC 1 through the galvanic isolation unit 4, which allows you to refuse additional power sources. This advantage in comparison with analogues expands the scope of ASK ES, namely, it allows you to create portable connection control systems.

The introduction of the claimed utility model of the microcontroller unit for high-speed processing of measurement results, the galvanic isolation unit of the control personal electronic computer with the control unit at the level of the USB2.0 interface and the organization of control and power supply of all ASK ES units from the USB2.0 interface bus of the control PC allows to achieve technical result, namely: to increase the efficiency of control of electrical connections of wire and printed wiring by increasing the speed and reliability of con Rola, as well as to extend the class of controlled objects containing passive electronic components, including electrical communication with ground-controlled equipment.
