FIELD: machine building.
SUBSTANCE: invention relates to chemical and general machine building, in particular to safety systems preventing emergency development. Under the method of forecast of the emergency development during accident at the explosive facility that means use of the monitoring system with the processing of the received information relating the dangerous zone to make solution on the emergency prevention, in the test chamber the model of the explosive facility is installed, and along its internal and external perimeters the video cameras are installed for video monitoring of the emergency development during accident at the explosive facility, that is simulated by means of installation in the model of the explosive fragmentation element with explosion initiator, at that the video cameras are made in explosion-roof design, and video camera outputs via the internal cavity of inserts are connected with the block, by its the ongoing processes of the model process parameters change are recorded and registered, then using system of analyzers the recorded oscillograms of the ongoing processes of the explosive facility model process parameters change are registered, and in ceiling part of the model the aperture is made, it is covered with the explosion-proof element free installed on three resilient rods, one end of each rod is rigidly fixed in the model ceiling, and on the another end the horizontal bar is secured, between the explosive fragmentation element and aperture the three-coordinate explosion-proof pressure transmitter is installed, its output is connected with input of the recording and registration devices block, and at both sides from the pressure transmitter the temperature and humidity transmitters are installed, the monitor temperature-moisture mode of the model, their outputs are also connected with input of the recording and registration devices block, and internal and external surfaces of the model guard are provided with glued on strain sensors, their outputs are also connected with input of the recording and registration devices block, after processing of the obtained test data the information data base of the emergency development during accident at the explosive facility is made, and mathematical model is prepared to forecast prevention of the emergency during accident at the explosive facility.
EFFECT: increased efficiency of protection of the process equipment and people against emergencies by possibility of forecast of the emergency development during accident at the explosion dangerous object.
