Description

The utility model relates to the field of testing and debugging software for control devices of complex energy facilities controlled during operation by a large number of parameters, for example, aircraft gas turbine engines.

A device for monitoring and debugging programs containing interconnected computers, a group of registers, comparison nodes, triggers, AND, OR, NOT elements, a counter, an adder and a delay element is known.

The operation of the device begins with the installation of the registers of the start and end addresses of the commands of the interrupting program, as well as the period code of the main cycle of information processing in the computer. This code determines the duration of each next step in the execution of debugged programs. The time of the next step of program execution is counted by a counter. At the end of the count, the device generates a signal that enters the computer interrupt system.

During the execution of the interrupt program, the real time is not counted by the counter and the real-time scale, determined by the period of the main cycle of information processing in the computer, is not violated.

When the computer is working, the address of the command to be executed is entered into the command address register, which, through the first information input of the device, goes to the second inputs of the first and second comparison nodes. An output appears at the output of the first comparison node when the start address of the interrupt program matches the address typed in the first register, and at the output of the second comparison node when the end address of the interrupt program matches the address typed in the second register. The inclusion of each command is accompanied by a control signal. This signal arrives at the control inputs of the comparison nodes for polling the comparison nodes. At the output of the trigger, a signal appears that is equal in length to the execution time of the interrupt program with all the delays caused by the intervention of the programmer. This signal prohibits the passage of pulses from the generator to the counter input of the counter and, conversely, allows the counter to work when the device operates in the area of working debugged programs. On the tumbler register, the reverse code of the clock interrupt period is dialed, which is overwritten to the counter at the moment the last overflow signal is generated. The overflow signal goes to the third control output of the device.

The programmer who debugs the program sets the control mode on the control register. In this case, single potentials appear at the outputs of one of the registers. Each access command in RAM is accompanied by a control potential, which comes from the processor through the control input of the device to the input of the And element, the first input of which receives the continuous potential of the first output of the control register. From the output of the first element, the positive potential through the second OR element is supplied to the control input of the third comparison node and thereby allows the comparison of information typed in the third register with the contents of the cell address register. The contents of the RAM cell address register through the first group of AND elements and OR elements are fed to the second information input of the third comparison node. If the contents of the registers of the cell address coincide at the output of the comparison node, a resolving potential will be generated that goes to the input of the fourth AND, the second input of which receives the resolving potential from the output of the first OR element. The signal from the output of the fourth AND element through the seventh AND element and the third OR element is supplied to the second control output of the device, which is connected to the device register. If the contents of the registers do not match, information about the program failure is displayed.

(see RF patent No. 2050588, class G06F 11/28, 1995)

As a result of the analysis of a known device, it should be noted that its use allows combining in time the procedures for detecting and localizing errors. If an error is detected, the moment of its manifestation is recorded. In this case, the intermediate information available in computer converters at a given interval for executing debugged programs is also recorded and can be measured. This allows you to localize the error already at the first test run, or select the correct version about the source of the error.

However, the known device conducts testing of programs without taking into account the individual characteristics of the software in which it will be introduced, as well as without taking into account the individual characteristics of the energy object, which will include the software with the program, which reduces the effectiveness of testing and leads to the need for final development of the program directly at the energy facility, which leads to the need for a series of commissioning (test) launches of energy tisticheskogo object.

A known system for monitoring programs containing a processor, the first input-output of which is connected to the input-output of the system bus of the computer and random access memory, the input-output of which is connected to the second input-output of the processor. The system also contains a memory block for the address of the location of the data blocks, the first input of which is connected to the first output of the processor by a bus for loading the addresses of the location of the data blocks, a block for comparing the addresses of the sample of commands with the addresses of the location of the data blocks, the first input of which is connected to the first output of the memory block of the addresses of the data block, the second input is connected to the second output of the processor by a bus for sending addresses of a sample of commands, and the output is connected to the first output of the processor by a bus for address matching signals. The system also contains a block for calculating the signature of the data blocks, the input of which is connected to the second output of the memory block of the address of the location of the data blocks, and a signature comparison unit, the first input of which is connected to the second output of the block of the address comparison of the sample commands with the addresses of the data blocks of the signaling bus about the address mismatch, the second input is connected to the output of the block for calculating the signature of the data blocks, the third input is connected to the third output of the processor by the bus for supplying the signature of the program blocks, and the output is connected to the second output th processor bus signaling the coincidence of signatures.

During the operation of the system when monitoring programs during the loading of data blocks from the network or external media into the random access memory, the addresses of the location of these data blocks are stored in the memory block. In addition, for each such data block in the signature calculation unit, a corresponding signature (checksum) is calculated. The addresses of the placement of data blocks from external media and the network, and the corresponding signatures corresponding to these blocks, are stored in the memory block of the addresses of the location of the data blocks and the signature calculation block of the data blocks, respectively.

When the program is executed, the addresses of the instruction fetch by the processor are compared in the address comparison unit with the addresses stored in the memory block with the location addresses of the data units from the network or external media. If the addresses match, the program execution is interrupted and the processor proceeds to anti-virus protection procedures with access restriction; if the addresses do not match, the signatures of the program blocks executed by the processor are compared with the signatures of the data blocks calculated and stored in the block. If the signatures do not match, then the program execution continues, and when the signatures match, the program execution progress is interrupted and the processor proceeds with anti-virus protection procedures with access restriction.

(see RF patent for utility model No. 107621, class G06N 7/00, 2011) is the closest analogue.

As a result of the analysis of the known system, it should be noted that it, like the one given above, provides diagnostics of programs without taking into account the individual characteristics of the object that it controls, which increases the testing time and reduces its reliability.

The technical result of this utility model is the development of a software debugging stand for a digital device for controlling an energy object, which ensures high reliability of diagnosing programs, as well as reducing the amount of time and resources of an energy object for debugging the program of its control device.

The indicated technical result is ensured by the fact that in the debugging stand of the software of the digital device for controlling an energy object, including a program unit for inputting a test program for a digital control device, interface units, a comparison unit, as well as a control unit, a reference block of reference parameters of the energy object and a registration device and visualization, the new one is that the stand is equipped with a software module designed to introduce a program that characterizes the mat The statistical model of the energy object and its systems, the program unit and the program module are connected to the control unit, the program unit is connected via interface blocks to the program module, the output of the program module being connected to the first input of the comparison unit, the second input of which is connected to the reference parameters block of the energy object and the output is with an archiving unit and a recording and visualization device, while the program unit designed to enter the program under test is mounted with the possibility of replacing it with a qi frovoy device control energy object.

The essence of the utility model is illustrated by graphic materials, which show a diagram of the debugging stand of the software of a digital device for controlling an energy facility.

The debugging stand for the software of a digital device for controlling an energy object includes a program module, in the program block 1 of which there is a program reflecting the mathematical model of an energy object (for example, an aircraft gas turbine engine), and in program block 2 there is a program reflecting the mathematical model of its systems.

The stand also includes a control unit 3.

The program module is connected via the interface blocks 4 and 5 to the program block 6 intended for entering the test program (let it be the control program of the digital device for controlling a gas turbine engine - an electronic controller).

The output of the software module is connected to the first input of the comparison unit 7, with the second input of which the output of the block 8 of the reference parameters of the energy object is connected. Block 8 contains the parameters of the object, in this case, the gas turbine engine, obtained during its acceptance tests. The output of the comparison unit is connected with the archiving unit 9 and with the registration and visualization device 10, which is most convenient to combine with the control unit 3. The control unit is connected with the software module and program unit 6.

The claimed stand is equipped with standard blocks and modules.

So, as a program module, a standard electronic computer can be used, in the program block which contains a program that reflects the mathematical model of the engine and its systems, which is equipped with a digital electronic controller, the control program of which is to be tested.

Interface blocks 4 and 5 are standard.

As the software unit 6 can be used with a standard processor.

As block 7, a separate software module in a computer environment can be used.

As block 8, a separate software module in a computer environment can be used.

As block 9, a standard block with a corresponding subroutine can be used.

As a registration and visualization device, a computer monitor can be used.

The claimed stand works as follows.

Let us examine the operation of the stand using the example of debugging a program of a digital electronic regulator of a gas turbine engine.

To debug a program, it is entered into program block 6, programs of a mathematical model of a gas turbine engine and its systems (fuel, air, cooling, etc.) are entered into program blocks 1 and 2 of the program module, and the digital electronic controller will work as part of it.

It should be noted that the use of mathematical models of engines in the management of their work and their diagnosis has been known for a long time from the prior art, see, for example, RF patents No. 87467, 2406990.

From the control unit 3, program blocks 1, 2, 3 are launched. The control program commands from block 6 are executed by the software module. The results of the program execution from blocks 1 and 2 are transferred to the comparison block 7, where they are compared with the parameters stored in block 8 and the comparison results are transferred to the archive 9 and to the recording and visualization device 10 for the operational control of the program debugging progress. According to the test results, if necessary, carry out a program correction.

Then, in place of the program unit 6, a standard digital electronic controller is installed, the program unit of which contains the tested one and, if necessary, the program adjusted according to its results, and, if necessary, install other interface units 4 and 5 that communicate with the electronic controller program blocks 1 and 2, and, similarly to the above, carry out repeated testing of the program embedded in the program block of a full-time digital electronic controller.

After repeated testing, if necessary, the program is adjusted according to the test results, after which the digital electronic controller is installed on a standard gas turbine engine and the program is finally diagnosed at the power plant.

Fulfillment of the claimed stand allows for a very reliable diagnosis of the program by conducting its testing in three stages: according to the mathematical model of the energy object and its systems at the first stage, taking into account the design features of the digital electronic controller at the second, and taking into account the individual characteristics of the real energy object - at third. An advantage of the design of this stand is also the reduction of time and resource costs of an energy facility for debugging the program of its control device.
