FIELD: machine building.
SUBSTANCE: invention relates to chemical and general machine building, in particular to safety systems, preventing development of emergency situation. Disclosed is method of emergency development prediction during accident on explosive facility, consisting in, that using monitoring system with obtained information on hazardous area processing for making decision on emergency situation preventing. Explosive facility mockup is installed in test box, and along its internal and external perimeters video cameras are arranged for video monitoring of emergency situation development process during accident on explosive facility, which is simulated by mounting explosive splintery element with explosion trigger in mockup. Video cameras are made in explosion-proof version, and outputs from video cameras are connected through spacers inner cavity to unit, by means of which the processes of change of parameters in the model are recorded and registered. Registering changes of process parameters in explosive facility mockup recorded waveform processes by means of system analyzers, and in mockup ceiling part opening is made, which is closed with explosion-proof element, installed freely on three resilient pins, one end of each of which is rigidly fixed in mockup ceiling, and at second horizontal bar is fixed between explosive fragmentation element and opening. Installing three-dimensional pressure sensor in explosion-proof design, which output is connected to recording and registering equipment unit input, and at both sides of pressure transmitter temperature and humidity sensors are installed, controlling temperature and humidity conditions in mockup, which outputs are also connected to recording and registering equipment unit input, and mockup enclosures inner and outer surfaces are with glued strain sensors, which outputs are also connected to recording and registering equipment hardware input. After processing of obtained experimental data forming data base on emergency situation development in case of accident at explosive facility and drawing up mathematical model, forecasting emergency prevention in case of accident at explosive facility.
EFFECT: technical result is increase in efficiency of process equipment and human resources protection from emergencies due to possibility of emergency situations development prediction in case of accident at explosive facility.
