Can analysis decision subsystem by stage fire deploy troops on garrison duty mesh module, stage detection scheme setup module, stage detection scheme generate
Module forms,
The stage fire is deployed troops on garrison duty, and to include stage grid temperature data storehouse, stage grid flue dust database, stage red for mesh module
Outer camera database and stage grid visualization model,
The metrical information and positional information of the in store each temperature sensing sensor in stage grid temperature data storehouse, are surveyed every time
Amount can all update the metrical information of temperature sensing sensor；
The metrical information and positional information of the in store each sense smoke sensor of stage grid flue dust database, are surveyed every time
Amount can all update the metrical information of sense smoke sensor；
The metrical information of the in store each thermal camera of thermal camera database, detects center and installation site
Information, measures the metrical information that can all update thermal camera and detection center location information every time；
Each sensor is preserved positional information, temperature information and flue dust in the database by the stage grid visualization model
Information is illustrated in a virtual three-dimensional stage set, generates the map of stage；
The stage detection scheme setup module sets temperature-sensitive according to the demand at scene and feels each alarm level of smoke sensor
Threshold value, sensor priority level, if need thermal camera to further confirm that；Wherein temperature sensing sensor needs only to set
The size of each temperature alarming threshold value, and the size of each temperature alarming threshold value will not only be set and also to set by feeling smoke sensor
The size of smokescope alarm threshold value is put, thermal camera then preferentially sets threshold temperature, its company is set further according to threshold temperature
Continuous scanning range, scanning accuracy, scanning direction；
The stage detection scheme generation module is used for the control signal for generating detection scheme, its composition is as follows：
Hardware interface database, record and the compensation of the address of hardware interface, the species of sensor, sensor of each sensor
Value；
Task allocating module, according to setting priority level, the species of the address of hardware interface and sensor, unit inspection gap most
The control signal queue of short principle generation sensor inspection；According to the measurement of the setting generation thermal camera of thermal camera
Center track；
Thermal camera scheduler module, one or more thermal camera work are dispatched for system, include more as needed
The location algorithm of selection algorithm and thermal camera the alignment measuring center of thermal camera；
Stage decision-making module, for the measuring signal of each sensor and thermal camera to be contrasted with the threshold value set,
And then determine whether to carry out fire alarm and corresponding alarm level, for needing what is further confirmed that with thermal camera
After more than certain threshold value, thermal camera can be dispatched and further confirmed that, confirm just to alarm after result is correct.
3. the method for work of stage fire hazard monitoring system according to claim 1, it is characterised in that：Step（2）Described in
Priority level refer to that setting for fire scheme will not only set each alarm level of each measurement point sensor
Threshold value, its grade include early warning, alarm, serious, there is provision of the priority level of each measurement point sensor, the priority level bag
Include and ignore, is common, is important, is particularly significant, if provided as ignoring, the measurement point can be skipped when inspection is patrolled, be arranged to very heavy
It then can all be measured when each round is examined and patrolled, be arranged to important, can measured once when every two-wheeled is examined and patrolled, and be arranged to
It is common then can every three-wheel examine patrol carry out one-shot measurement.
