Fig. 1 fault detection and diagnosis block diagram of system.
Embodiment
For four machines test run Fault monitoring and diagnosis in parallel system, the present invention is described in detail below.
Figure 1 shows that Fault monitoring and diagnosis system architecture diagram, system comprises sensor that engine carries, gathers leader cable, data switch cabinet, data acquisition equipment, data acquisition and backup computer, fault detection and diagnosis computing machine, acoustic-optic alarm etc.In the block diagram of system as shown in the figure, engine is arranged on the important and main portions of designer's care from belt sensor, in order to obtain performance parameter before test engine dispatches from the factory, has installed from belt sensor at main portions.Data switch cabinet completes Signal transmissions between foreground sensor image data and back-end data collecting device, and engine is connected with data switch cabinet by leader cable from belt sensor, each connection leader cable is provided with mark, can maintains easily and overhaul leader cable.Data acquisition equipment mainly realizes the functions such as parameter acquisition, filtering, amplification, transmission.Data acquisition and backup computer have two aspect effects, one, be responsible for engine important parameter answer work of recording workpoints, secondly, send engine failure monitoring and diagnosis parameter; Fault detection and diagnosis computing machine completes parameter acquiring, parameter grouping, parameter detecting, abnormal parameters judgement, sensor failure detection, breakdown judge, sends alerting signal, sends shutdown command function.
In illustrated system architecture, and if only if meet fault emergency cutoff rule time, send sound and light alarm signal and send instruction to control system simultaneously, judged by control system and whether shut down.
Four machines test run Fault monitoring and diagnosis in parallel method, mainly comprises the following steps:
1] actual value getparms
Obtain the digital quantity value of the malfunction monitoring point parameter required for Fault monitoring and diagnosis system, and digital quantity value be synchronously converted to analog quantity, i.e. the actual value of malfunction monitoring point parameter,
The digital quantity value of malfunction monitoring point parameter by being arranged on the sensor collection carried out on multiple engines of test run, and obtains after data processing,
2] parameter grouping
For the test run in parallel of this four machine, what first will solve is the grouping problem of engine parameter.When data acquisition and backup computer by all types of parameters that obtain from motor head (as pressure, temperature, vibration, water attack, pulsation, rotating speed etc.) digital quantity value when packing in real time and be sent to Fault monitoring and diagnosis computing machine by network, software is used to abandon non-faulting monitoring point parameter, obtained parameter is classified according to engine, the parameter of same engine is divided into one group, the dissimilar parameter of same engine gathers under same rule base, rule base comprises multi-class data Ku Biaoge, every class database table is for storing the threshold value calculation method of a class parameter in different time points, the rule base of different engine arranges not identical, this completes the grouping work of engine parameter.

4] sensor failure rule
Sensor failure rule is independent of Fault monitoring and diagnosis rule base, when Fault monitoring and diagnosis computing machine receives data, first carry out failure detection, comprise open sensor, short circuit sensor, and sensor values oscillation on large scale etc., all think sensor failure when this takes place, rejected, do not entered within the scope of Fault monitoring and diagnosis DBD database diagnostics, avoid false alarm occurring and not reporting to the police, otherwise, carry out next step;
5] abnormal parameters judges
If malfunction monitoring point continuous parameters repeatedly exceeds threshold range, then this abnormal parameters, carries out early warning.
6] breakdown judge
When detecting extremely, start parameter and judge, between each monitoring parameter of separate unit engine interior, logical relation is "AND", and namely any multiple abnormal parameters of engine interior shows this engine abnormity.
Logical relation between four engines is "or", namely has an engine abnormity, and Fault monitoring and diagnosis system shows four machines test run results abnormity in parallel.
Each malfunction monitoring point parameter has logical relation in group, and between group, do not have logical relation, the method improves the precision of Fault monitoring and diagnosis system.
Fault location function main manifestations can provide accurate time of failure when being fault generation, which platform engine there occurs fault, have which parameter, fault that position etc. occurs.This is preliminary localization of fault result, the later stage with the continuous accumulation of firing test data and fault test run data and collection, then through network training, can to the reason occurred that is out of order.
Fault location function is mainly manifested in, and when the test runs in parallel of four machines are broken down, Fault monitoring and diagnosis system can show fault origination point in real time, is that problem has appearred in which platform engine, and can the position even reason that occurs of Primary Location fault.
Based on the optimization to above basic technical scheme, for improving the accuracy of the present invention's diagnosis further, the present invention has also made the improvement of the following aspects:
1] when have in separate unit engine four acquisition parameters three continuous exceed threshold value three times time, thinking that this engine has fault, is "or" relation between four engines, and now fault diagnosis system sends fault off signal to control system.For solving the logical relation between separate unit engine four parameters, between four engines, adopt database technology building database form, the inquiry of each parameter threshold is carried out with lookup table mode, time inquiring, Adjustable calculation is inquired about, software is contrasted by accessing database form and actual measurement sensor signal, thus carries out interpretation.
