Abstract

The invention discloses an underground flood alarming method based on image and flood monitoring. The method comprises: placing cameras on driving working faces, coal faces, or other working faces of an underground coal mine to which water inrush accidents may occur, and installing water sensors on walls of roadways the cameras monitor; when the sensors monitor that a set region of a camera video image has abnormal water flow, and water flow duration exceeds set time threshold or flow increasing speed exceeds a set threshold, and a detector of the water sensor is immersed, giving out a flood alarming signal. The alarming method gives full consideration on characteristics of floods in an underground coal mine, and the method is simple to apply. Corresponding measures are automatically taken in time, and the method accurately gives out an alarm on mine water inrush in first time, and buys valuable disaster relief and escape time for underground personnel who are not on the site of the water inrush and in other regions.

Description

Based on the down-hole floods alarm method of image and flood monitoring
Technical field
The present invention relates to a kind of down-hole floods alarm method of monitoring based on image and water yield, the method relates to the fields such as image steganalysis, sensor, communication.
Background technology
Coal is China's main energy sources, accounts for primary energy 70%.Coal industry is high risk industries, and the accidents such as gas, floods, fire, top board, coal dust annoying Safety of Coal Mine Production.In China's coal-mine generation severe and great casualty, natural calamity larger to mine harmfulness during mine water disaster, calculates with the number of coal mining accident death, water damage accident accounts for 15.72%, is only second to gas and roof accident, occupies the 3rd, after mine generation floods accident, its harm comprises:
1, to destroy by rush of water tunnel, pile things on, to flood and shutoff personnel.
2, with gushing water, have a large amount of coal slimes and rock alluvial tunnel, cause difficulty to personnel escape.
3, damage equipment.Down-hole electrical equipment, after cable is immersed in water, its insulating capacity declines rapidly, causes difficulty to the transport of down-hole, ventilation, draining etc., and the probability of surviving of the personnel that do not flee from time is reduced.
4, to gush out a large amount of toxic and harmfuls, the life condition environment of not fleeing from personnel is in time worsened more.
In sum, mine water disaster is the serious disaster in colliery, must accomplish promptly and accurately in coal production to the warning of mine water disaster.Current floods early warning based on the hydrology detection prevention, underground for probing water, tendency phenomenon observe and, hydrology detection and underground for probing water can prevent down-hole floods accident, but due to hydrologic regime complexity also may be there is, design improper, take effective measures, manage improperly and the reason such as thought paralysis of people, hydrology detection and underground for probing water can not prevent the generation of gushing water completely, more can not report to the police to the down-hole gushing water of burst; Based on artificial micro-judgment, there is larger subjective factor in the observation of tendency phenomenon.
At present for on-the-spot water inrush accident, the artificial warning of main dependence Field Force, but when gushing water occurs in unattended time or region, or Field Force flees from hastily and fails initiative alarming, control room just cannot obtain the information that gushing water occurs timely, down-hole relevant staff cannot be notified in time, so that can not take emergency measures in time to water inrush accident, easily cause the out of control and casualties of water damage.For effectively reducing the mine property loss and casualties that floods cause, need new down-hole floods alarm method, exactly down-hole gushing water can be reported to the police the very first time, for not striving for the valuable disaster relief and escape time other region personnel in the pit that scene occurs.
Summary of the invention
When the present invention, according to down-hole, water inrush accident occurs, have a large amount of water outwards spouting, and constantly, the feature constantly increased proposes a kind of down-hole floods alarm method based on image and flood monitoring.Underground coal mine driving face, coal-face or other may there is the place such as the scope of operation of water leak accident and place video camera, the tunnel be communicated with tunnel, video camera place all, particularly place water sensor lower than the tunnel of camera plane; Real-Time Monitoring is carried out to the immersion situation in vedio data and tunnel, there are abnormal current when monitoring setting regions in camera video image, and the current duration exceedes the time threshold of setting or current pushes the speed when exceeding setting threshold value, be then judged to be data exception; And when finding that tunnel immersion then sends floods alarm signal.Described floods alarm method specifically comprises:
1. camera installation locations is near top, tunnel or be highly greater than 2 meters, and install secondary light source video camera is other, it is consistent that light projecting direction and camera video gather direction; Close auto-focusing and the automatic white balance function of video camera.
2. the probe of water sensor should be installed on wall, and probe quantity is no less than 2 groups, and order is installed from low to high, and often group probe interval is not less than 5 centimetres, and minimum one group of probe is not more than 5 centimetres apart from tunnel distance from bottom; The circuit box of water sensor is fixed on tunnel wall or top, tunnel, and setting height(from bottom) is not less than 1.5 meters.
3. the subregion A in pair camera supervised scope sets, and adds up, obtain sequence H to the pixel count of gray value i each in every frame video image setting regions A i; The arithmetic mean of instantaneous value of the pixel count of each gray value of computing K two field picture, obtain sequence S i; Ask and be more than or equal to setting gray value M 1pixel summation D s, and by last frame image as a setting image b (x, y) store, interval time T mto D supgrade with b (x, y); Ask in latest image frame at interval of P frame and be more than or equal to setting gray value M 2pixel summation D h, work as D hbe more than or equal to D ssetting threshold value M 3time, i.e. (D h-D s)>=M 3time, trigger early warning, and store b (x, y); As (D h-D s) < M 3, then D is upgraded swith b (x, y), then upgrade D swith b (x, y); K, P, M 1, M 2, M 3, T mobtain by measuring setting or artificially setting.
4. after entering modes of warning, at interval of Q 1frame carries out accumulated deficiency process to the real time video image f (x, y) of camera acquisition and the background image b (x, y) that deposits, and accumulated deficiency operational formula is:
P in formula n(x, y) is setting regions for the accumulated deficiency image initial value having processed n frame is 0, A, T 1for setting gray threshold; By accumulated deficiency calculation process Q 2after frame, ask and be more than or equal to setting gray value T 2pixel summation D t, as met D t>=M 4, be then judged to be that view data is abnormal; M in formula 4for the threshold value of setting; Q 1, Q 2, T 1, T 2, M 4obtain by measuring setting or artificially setting.
5. when monitor view data abnormal after, interval time T jmonitoring water sensor data variation, reports to the police when water sensor monitors immersion, then sends floods alarm signal, T jobtain by measuring setting or artificially setting.
