Abstract

The invention discloses an underground flood alarm method based on image and water inflow monitoring. The alarm method includes the steps that cameras are placed on an underground coal mine tunneling working face, a coal working face or other operation faces possibly having a water inrush accident, and a flow monitoring device is placed at a downstream position of a drainage channel of a roadway monitored by each camera; when it is monitored that abnormal water flow appears in a set region in video images of the cameras, moreover, the duration time of the water flow exceeds a set time threshold value or water flow increasing speed exceeds a set threshold value, and meanwhile the flow of the corresponding drainage channel is abnormal, a flood alarm signal is sent out. The alarm method fully considers the characteristic of a coal mine coal working face flood and is easy to implement, corresponding measures are taken automatically in time, an alarm can be given for water inrush of a coal mine accurately at first time, and valuable rescue and escape time is bought for underground staff, not at the flood site, in other regions.

Description

Based on the down-hole floods alarm method that image and water yield are monitored
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 of monitoring based on image and water yield.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, monitor the escape canal downstream position placement flow monitoring equipment in tunnel in video camera institute; Real-Time Monitoring is carried out to vedio data and water burst data on flows, 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 monitoring finds that the threshold value that water yield increases above setting then sends floods alarm signal.Concrete grammar 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.
2. water yield is by being arranged on the flow monitoring monitoring of equipment in the escape canal in tunnel, video camera place; Flow monitoring equipment is arranged on the escape canal downstream of video camera position; Flow monitoring equipment installation site is not in camera supervised region; Should try one's best near video camera at the situation down-off monitoring equipment meeting above condition.
3. the subregion A in pair camera supervised scope sets, and in every frame video image, in setting regions A, the pixel count of each gray value i is added up, and obtains sequence H 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 in setting regions A, 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:
in formula
P 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, calculates and monitors escape canal data on flows and change, when at time T jin, meet then send floods alarm signal, L in formula ifor the escape canal data on flows of Real-time Collection, L sfor the escape canal data on flows average before view data exception, R is the escape canal flow growth rate threshold value of setting; T j, R is by measuring setting or artificial setting obtains.
