Abstract: Problems of new automation system implementation for remaining life determination of different longly operated water conveyance structures with their reliability parameters taken into account are considered in the article. Software allows to evaluate risk-ness of failure and to predict technical state of different elements. Technical potential of the system application makes it possible to calculate geometric characteristics of defects and various damages both on the structure surface and inside of its individual elements.

Key words: automation, water conveyance structures, remaining life, software and hardware system, reliability parameters, technical state.

On the ground of research and the data received, a detailed analysis of technical state of longly operated water conveyance structures for both the further classification of their defects and damages and prediction of their remaining life. Software and hardware system was constructed on the predicted water filtration time starting with the beginning of a structure inspection. In the course of inspection conducted, the software and hardware system (SHS) forecasts losses both of the structure bearing capacity as a whole and its individual elements from the time of a damage origin. Further the SHS predicts the time for the complete loss of the structure bearing capacity using different regressive relationships [1].

The results of studies on location and observations are used as a source material for the SHS programmed environment [2]. They include:

- the results of check-ups during a long operation of water conveyance structures with filling in a registry where defects and their time variations are recorded;

- the results of usage of non-destroying control devices (NСD); the results of data processing received with the HСD;

- the results of the SHS inspection with the help of different technical schemes reiterating a structure form with forecasting their remaining life in the future.

The SHS software allows to evaluate riskness of a failure and to predict technical state of different elements of water conveyance structures in the future:

- minor - К ≤ 0,15;

- moderate - К = 0.16.....0.30;

- high - К = 0.31....0,50;

- emergency condition - K> 0,51.

The SHS is developed on the basis of the Microsoft Access [3] system of data base control and consists of tables, forms, inquiries, macroses and different modules. In the SHS programmed environment; a choice of an inspection technical scheme for different construction elements of water conveyance structures is foreseen. The realised forms contain a set of properties and methods reacting on the system events and the events arising when interacting with a user.

The main push-button form contains a description of the programme purpose, a version and a functional part [2, 4]. In the functional part, there are the buttons by which it is possible to open a list of the structure elements studied and to move to editing a handbook of the structure technical parameters.

On the basis of the data received at the previous stages, a remaining life prediction for water conveyance structures is carried out. Technical stages for the SHS inspection [5, 6] are as follows:

1) Under a reconnoitring inspection of the surveyed water conveyance structure a volume, specific character and a direction of the inspection is determined, a substantiation for the corresponding SHS scheme is conducted, as well [7];

2) When water is absent, the SHS hardware is placed into the water conveyance structure, with one of its schemes - frame of rods - copying the structure geometry [5, 8];

3) The SHS moves about the structure and during the structure inspection the data from the SHS motion sensor and aerial blocks come into the processing module [6, 9];

4) In the processing module a detailed interpretation of the data received from the NCD aerial blocks and positioning of an arragement for the defects and damages with the help of GLONASS takes place;

5) In the SHS programmed environment identificators for defects and damages of the structure elements are automaticly introduced. Recording the data about new defects includes the following fields: zone, diameter, depth, R_compr. and location, specified with the help of GLONASS;

6) The volume of damages and their number for the period of the structure long operation is calculated. At the same time, the fields of the table part - the volume and structure state, as well as the fields of the form heading part are filled in automaticly;

7) In the SHS programmed environment expected places of water filtration through the water conveyance structure are revealed;

8) According to empirical relationships received, a computation of the expected dangerous volume of damages for the further operation of the water conveyance structure is carried out [2, 10];

9) Forecasting of the structure remaining life, with their reliability parameters taken into account, and comparison with the other technical inspections is conducted. The results of the calculations conducted can be typed in the form of a table. The screen forms are intended for presenting the data to the operating organization. All the data received are processed in the SHS and kept to form the data base of defects and damages for the inspected water conveyance structures to carry out their further inspections of the defects time variations.

In the SHS programmed environment there is a possibility to output georadar sounding profiles from, each aerial and to process the data received depending on the geometry of the scheme technical part. In the SHS environment it is also possible to classify defects and to conduct a coordinate reference with the help of GLONASS in order to establish changes of defects and damages for the operation period under the following inspection. When considering the SHS functioning, it is necessary to take into account the corresponding peculiarities of its operation. The main rules for determining and forecasting the remaining life of the longly operated water conveyance structures as well as for revealing defects and damages, evaluating their suitableness for the operation in the future, with the reliability parameters taken into account are established.

Conclusions

1. To predict the remaining life of the water conveyance structures, with their reliability parameters taken into account, the SHS usage is proposed.

2. Software and hardware as well as the SHS user's interface are realised.

3. The SHS presented to solve the problems of forecasting the remaining life of water conveyance structures can be used to form the data base when operating these structures for a long period and that allows to prolong the life cycle of the water conveyance structures, with the reliability parameters taken into account.
