The invention relates to the field of measuring and control technology and can be used to control various objects.

A known system for centralized monitoring of electronic products copyright certificate № 744481 G 05 In 23/02, G 06 F 15/46, SU, containing a Central control device, the memory device, the data processing unit and each control channel of the control stand. The system also contains a controlled product, and each control stand consists of a buffer register, shaper signal analyzer input signals, the first and second switches, and a control unit. In addition, the system includes a third switch, the input register and the input block, and each control stand - referencing dynamic tests, the counter products, register non defective product, the control unit input code, item, element, OR, with the control device, the memory device, the data processing unit and input block part of the computer.

Its disadvantages include greater complexity, due to the implementation of the monitoring channels separate control stands.

The closest to the technical nature of the proposed system is the system of automatic control of parameters of electronic circuits copyright certificate № 985764, G 05, 23/02, SU. This system sod is REIT management computing machine, measuring station with the working posts. Each measuring station includes a switch operating positions, the case of working positions, the switch of the findings, the case of test combinations, the unit of power sources, measuring unit, the first element OR the register of readiness, the second element OR block valves, the address decoder, the unit of analysis, a reversible counter, registers the upper and lower values.

The management computer (PC) performs sequential scanning software readiness of each measuring station, identifying first work post, ready to work in this measuring station. Defining the post, ready to work, the management computer issues at the station first test the combination of the value of the stimulating signal, and switch leads through the test case combinations is populated with the number of output which is connected with the measuring unit. After the starting signal, the measuring unit through the interval of time required for measurement, emits code measured value to the unit of analysis. The unit of analysis shall evaluate the conformity of a measured value is valid and returns information to the control computer. Thus, control of control objects on the working positions and for different measuring stations, which provide the try checking of controlled objects by means of, included in them.

The disadvantage of this system is the large amount of equipment, due to duplication of devices in the measuring stations for performing the same functions, and the high complexity of the software implementation of the control, due to the division of control between the control computer and the measuring stations. Especially these defects are manifested for complex controlled products, which are characterized by a large amount of stimulating and controlled signals, supply voltage and a large amount of control programs.

In this case, the amount of duplicate equipment at different measuring stations becomes unacceptably large. At the same time, the speed of modern computers allows to neglect the task of saving the scope of their functions and the implementation of the improved performance due to equipment measuring stations. In addition, for complex controlled products speed control process is determined by the transients in the products and not the performance of the funds (including the computer) control system. Also the need for simultaneous control of several complex controlled products, as a rule, is absent.

When the division of control between the measuring stations upravlaushiy computer software implementation is carried out as in measuring stations, and the control computer, which from the point of view of programming are incompatible. In the software development and change are complex and require a lot of time. The ability to use language high-level programming practically difficult to implement.

To reduce the amount of equipment, simplify management process control, simplify software development and increasing its mobility offer automated control system containing objects of control, the control unit, the first input and the output of which is connected respectively to the output and input of the first memory block and the second input and output respectively to the first output and the input of the interface block, the second input and the output of which is connected respectively to the control outputs and the inputs of the unit power supply, unit test influences the measuring unit and the switch input and output signals, and the signal outputs of unit power and unit test influences connected to the first and second signal inputs of the switch input and output signals, the first signal output of which is connected to the signal input of the measuring unit, characterized in that it introduced N matching units, the power distribution of the signal, N blocks of control programs, each of which contains the evaluation unit, the second and third memory blocks, and the block program control, input and output respectively connected to the third output and the input of the control unit that (i+3)-th (where i is the block number of control programs and, accordingly, the object of control) inputs and outputs connected respectively to the outputs and inputs of the second memory blocks, a (i+4)-th inputs and outputs respectively to the first outputs and inputs units estimates, second inputs and outputs are connected respectively to the outputs and inputs of the third memory blocks, and the block signal distribution of the first the second inputs and the first output are connected respectively to the second, the third signal and outputs a third signal input switch input and output signals, and (i+1)-mi and outputs (i+2)-th inputs respectively to the first inputs and outputs matching units, second inputs and outputs are connected respectively to the outputs and inputs of control objects.

Each of the blocks of the control programs 4 contains the evaluation unit 13, the second memory block 14 and the third memory block 15.

Matching blocks 11 connect specific objects control 12 (OK) to the power distribution signals 10 and contain adapters, load impedance elements, cables.

The unit of power sources 6, unit test influences 7 and the measuring unit 8 includes a set of tools needed to control all OK. This takes into account the need the same tools that are included in these blocks, for different OK, i.e. most of the money is shared and used to control different OK.

The composition of the funds included in the blocks, is the optimal method of synthesis according to the criterion of minimum cost of the control system with the necessary parameters of the system reliability of the control performance.

The system is and works as follows.

OK 12 using block matching 11 is connected to the distribution unit signals 10. Using call block software control 3 sets corresponding connected OK the control program from the second memory block 14 is inserted through the control unit 1 in the first memory block 2. After the program starts, the control unit 1 via the interface block 5 in accordance with the control program for this OK transmits the necessary data control unit power supply 6, the unit test influences 7, the measuring unit 8, the switch input and output signals 9. The unit of power sources 6 and unit test influences 7 according to the control input to them, form the necessary voltage and test stimuli, respectively, which through the switch input and output signals 9 in accordance with control information received by him, proceed to block distribution of signals 10.

The distribution unit signals 10 groups received from the switch input and output signals 9 signals block power sources 6 and unit test influences 7 outputs for flow through the unit is connected reconciliation 11 on the test object 12.

Controlled signals from the test object 12 through the block matching 11 arrives at the input distribution unit signals 10, which groups them into outputs for submission is via the switch input and output signals 9 to the measuring unit 8, which converts the input signals into the code. The results of the transformation parameters from the measuring unit 8 is transmitted through the connection unit 5 and the control unit 1 to the evaluation unit 13 unit control programs 4. In the evaluation unit 13 evaluates the results of the conversion options on finding them within tolerance and is determined by the magnitude and sign of the deviations from the limits of tolerance and produces a parameter estimate - GOOD, NOT GOOD. Parameter estimation is memorized in the third memory block 15.

During operation of the system is the control of all parameters OK, the results of which the evaluation unit 13 provides a generalized assessment of the status of OK in General, which is transmitted to the control unit 1 and stored in the first memory block 2.

Similarly monitored all other OK.

The introduction of blocks of control programs containing the second memory blocks, the blocks of the evaluation, the third memory blocks, the block distribution of signals, matching units and unit call control programs can dramatically reduce the amount of system control sequential control OK by eliminating duplication of identical equipment in measuring stations that perform the same function for OK. Moreover, for complex OK one form of the reduction of the excessive amount of equipment will be significant the reduction in value.

The exception simultaneous operation of the measuring stations and the implementation of logic control, parameter estimation and evaluation OK in General in blocks of control programs in their implementation on modern high-speed computers will not lead to an increase in testing time.

In addition, the implementation of control programs on the Central control computer can simplify the provision of the necessary controls for process control and to use the developed software based on the programming language of high level.
