Method of designing computational process of testing equipment

FIELD: information technology.

SUBSTANCE: diagnostic tests are created when testing electronic devices. By executing a test, the computational testing process is realised and data packets are generated in an input/output device. The input/output device generates signals at outputs; the control equipment performs display and control of the computational process.

The invention relates to computing, and in particular to a method of constructing computational process of testing electronic devices, having in its composition computing module.

There is a method of constructing computational process of testing electronic devices in the production process, using diagnostic tests, namely, that the computational process of testing an electronic device is implemented in a computing module, and the control apparatus carries out his display, and management. ("Testable control unit and test / WEBBRAIN, AVELINE. - Scientific session MEPhI-2007. V.1 Automatics. Microelectronics. Electronics. Electronic measuring system. Computerized medical systems, p.94-96).

The method works as follows: when testing circuit boards, computer module through the instrumental serial port is entered, the input vectors (diagnostic tests), based on which the processing module generates the package on the instrument interface to the microcontroller device I/o, which actually specifies the signals on the output lines of the electronic unit of the device.

However, this method can be improved by moving the computational process that implements the diagnostic tests, n is the monitoring equipment and the organization of exchange with the device I/o transit through the computational module.

There is a method to the technical essence is the closest to the proposed and selected as a prototype.

The disadvantage of the prototype is:

- lack of effectiveness of control operations, data exchange and device input/output;

- the transition between diagnostic tests associated with reprogramming computing device of instrumental serial port.

- writing diagnostic tests carried out in a special development environment for computational module.

The aim of the invention is:

- minimization of time testing and labor;

- simplification of procedures for the management, control, analysis and processing of information during the test;

This objective is achieved in that the computing process, implemented by a computing module that is executed in the control apparatus, exchanging device I/o transit through the computational module.

On the drawing (figure 1) presents a functional diagram of a single information-logical link control equipment and devices I/o, which provides full control of the computing process, implemented on a control apparatus for input/output.

The control apparatus is connected to computing is to prepare with the help of the main interface. Computing device connects to the device I/o on the instrument interface.

The control apparatus includes software implementing computational testing process.

Computing module contains a generic software that implements support for unified information-logical link control equipment and devices I/o for the implementation of their bilateral exchange of information.

The method is organized as follows.

Computational testing process, performing diagnostic tests, implemented in a single software for equipment control.

In the course of performing diagnostic tests is the formation of packets in the format Protocol device interface, designed specifically for the device input/output. For each of the packets in the format Protocol device interface is formed by a certain number of packets in the Protocol format of the main interface designed to transfer them to the computer module.

The number of packets trunk interface F, made from packet device interface is defined by the following formula:

F = (round down ((h(N-1))/(k(M+1))))+1

N is the maximum number of data words data (ISD) Protocol magis the General interface;

M is the required number ISD Protocol device interface;

h - bit data word data according to the Protocol of the main interface.

k - bit data word of the data Protocol device interface.

The formula is used in algorithms 1 and 2 of figure 2, where

i - number ISD Protocol trunk interface (from 1 to N);

j is the number of the discharge ISD Protocol trunk interface (from 1 to h);

x is the number of IUD Protocol device interface (from 1 to M);

y is the number of the discharge ISD Protocol device interface (from 1 to k);

z parcel number Protocol trunk interface (from 1 to F).

Record information from monitoring equipment in the device I/o is implemented by forming apparatus control packet format Protocol device interface with the characteristic of recording information, from which F is formed of packets in the Protocol format of the main interface by algorithm 1 (figure 2), which are transmitted to the computing module. To obtain F packet, the processing module generates a package in the format Protocol device interface according to algorithm 2 (figure 2) and passes it to the device input/output.

The reading of information by the control apparatus from the device I/o is implemented by forming apparatus control packet format Protocol the device interface with a sign reading, from which the package 1 is formed in the Protocol format of the main interface by algorithm 1 (figure 2), which is transmitted to the computing module. On receiving a packet, the processing module generates a package in the format Protocol device interface according to algorithm 2 (figure 2) and passes it to the device I/o by reading information which is read by the control apparatus from the processing module, through time, defined as the maximum time sharing between computing module and device input/output.

Minimization of time and effort is due to the fact that there is no need to reprogram a computer module when switching between diagnostic tests. And they are established in the software interface monitoring equipment, without the use of special programming environments. Simplification of procedures for the management, control, analysis and processing of information is achieved through the use of a single software interface for hardware control, with full access to a computing process and engaged in its management.

The method was tested in the workplace, consisting of an industrial PC ROBO-4000-5163A acting as monitoring equipment; a control unit on-Board complex control of SPACECRAFT "GLONASS-K", acting as e is astronomo device, containing the Central instrument module, acting as a computing module, and interface modules mate, acting as input/output.

From the known to the applicant of patent information materials are not signs of a similar set of features of the proposed method.

The method of constructing the computational process of testing equipment, namely, that when testing electronic devices generate diagnostic tests; performing tests, implement computational testing process and generate data packets at the device input/output, input/output forms the output signals; the control apparatus carries out the display and management of computer process, wherein the computing process performed by the control apparatus, namely forms of diagnostic tests, produces the computational process tests and sends the data packets to the device I/o transit through the computing module, which includes software, which realizes the exchange between a control apparatus and device I/o; recording information from monitoring equipment in the device I/o is implemented by forming apparatus control packet format Protocol device interface with the characteristic of the recording information is AI, from which F is formed packets in the Protocol format of the main interface that is passed to the processing module, for obtaining F-package generates a package in the format Protocol device interface and passes it to the device I/o, while capturing information; the information is read by the control apparatus from the device I/o is implemented by forming apparatus control packet format Protocol device interface with a sign reading information from which the package 1 is formed in the Protocol format of the main interface, which is passed to the processing module, upon receipt of the package forms a package in the format Protocol device interface and passes it in the device I/o by reading the information which is read by the control apparatus from the processing module, through time, defined as the maximum time sharing between computing module and device input/output.
