Description
Technical Field
The invention relates to the field of image data processing, in particular to a direct-current emergency power supply applying a master-slave control mode and a control method thereof.
Background
In general, a dc emergency power supply includes a stationary ac uninterruptible power supply device which is mainly composed of an energy storage device (a storage battery) of a power converter and a switch (electronic or mechanical) to ensure power supply continuity, and is adapted to a load which allows interruption of power supply time in the order of milliseconds.
In order to ensure the success of fire suppression work, the robustness and reliability of a direct current emergency power supply which is responsible for supplying power to fire-fighting electric equipment are paid attention. For example, a primary load for fire electricity should be powered by two power sources, and when one power source fails, the other power source should not be damaged; the power supply form of the primary load comprises two paths of high-voltage power supplies, one path of high-voltage power supply, one path of low-voltage power supply, a diesel generator set or a storage battery pack; particularly important loads in the primary load are provided with emergency power supplies in addition to the two power supplies.
For example, a driving circuit of a fire emergency power supply proposed in chinese patent publication No. CN103746547a is used for driving a power module that implements inversion output of the fire emergency power supply, where the driving circuit includes: at least four optocoupler isolation driving modules which receive driving signals for driving the power modules; at least two power modules, each power module comprising two electrically connected power tubes; each power tube is electrically connected with one of the optocoupler isolation driving modules respectively, so that the corresponding power module is driven by the optocoupler isolation driving module to realize inversion output. When the four optocouplers are used for isolating the driving modules and the two power modules, the driving circuit of the fire emergency power supply is suitable for single-phase loads; when six optocouplers are used for isolating the driving modules and three power modules, the driving circuit of the fire emergency power supply is suitable for three-phase loads. In actual life, three-phase loads are most, so that the driving circuit provided by the invention can play a good role.
For example, a switching power supply circuit of a fire emergency power supply proposed in chinese patent publication No. CN103746343a, wherein the circuit comprises: a storage battery which provides an original power supply for the switching power supply circuit; the output module is electrically connected with the storage battery through a transformer and outputs multi-stage power supply voltage for normal operation of the fire emergency power supply through transformer transformation; the switch power supply chip is arranged between the storage battery and the output module and used for controlling the storage battery to transmit power to the output module and stabilizing the output power supply voltage of the output module; the switching on/off self-locking circuit is selectively and electrically connected with the switching power supply chip and is used for opening and closing the work of the switching power supply chip so as to realize self-locking of the switching power supply. The switching power supply circuit of the fire emergency power supply provided by the invention has the advantages that the standby power consumption of the fire emergency power supply is low, and meanwhile, whether the control system of the fire emergency power supply has faults or not can be detected, so that the expansion of the faults is prevented.
However, in the prior art, a specific backup time of the direct current emergency power supply, which is responsible for supplying power to the fire-fighting electric equipment, is not involved, so that the direct current emergency power supply with excessive backup is caused or appears, and excessive calling of the direct current emergency power supply is caused, or the direct current emergency power supply is insufficient, and under the condition that a fire scene is not completely and fully extinguished, the fire-fighting faucet cannot finish the fire-fighting treatment due to insufficient power supply. Obviously, the key point that the specific backup time is difficult to solve is that the required power of the fire-fighting faucet to be extinguished is different due to different smoke areas and different distribution areas of fire points in the smoke, and the required power of the specific different fire-fighting scenes is difficult to obtain an effective targeted analysis result.

firstly, for a fire-fighting vehicle with a built-in direct-current emergency power supply, synchronously controlling a water spray faucet and an infrared camera mechanism to keep the same direction and face a fire area of a fire building, and executing infrared picture acquisition on the fire area to acquire data of the temperature sensing condition of the fire area while adapting to the day and night environment;
Secondly, acquiring a smoke imaging area in a real-time infrared picture by adopting a targeted image processing mechanism, and determining a numerical value of a corresponding fire extinguishing power range positively associated with the area percentage based on the area percentage of the smoke imaging area occupying the real-time infrared picture, wherein the fire extinguishing power is the power of direct current emergency power supply required by completing the full fire extinguishing of a fire area;
thirdly, determining a specific value of predicted fire extinguishing power from the determined fire extinguishing power range based on the number proportion occupied by red pixel points in the smoke body imaging area, wherein a nonlinear function is adopted to represent a nonlinear mapping relation of the specific value of the determined predicted fire extinguishing power and the number proportion;
the nonlinear function is a function in which the relationship between the dependent variable and the independent variable is not linear, for example, the dependent variable is X, the independent variable is Y, the relationship curve of X and Y on the coordinate axis is not a straight line, and the specifically adopted formula may be y=a·x+b, where a and b are constants;

The key points of the invention are as follows: the method comprises the steps of carrying out targeted continuous processing on real-time infrared pictures of a fire scene, analyzing the smoke distribution area firstly and then analyzing the fire distribution area, wherein the numerical range of the predicted fire extinguishing power of a direct-current emergency power supply required by full fire extinguishing is reduced step by step, and finally, accurate predicted data is determined, so that key information is provided for the implementation of a master-slave control mechanism of a follow-up direct-current emergency power supply.
Next, the direct current emergency power supply and the control method of the present invention, to which the master-slave control mode is applied, will be specifically described in terms of embodiments.
First embodiment
Fig. 2 is an internal structural view of a direct current emergency power supply to which a master-slave control mode is applied, according to a first embodiment of the present invention.
As shown in fig. 2, the dc emergency power supply applying the master-slave control mode includes the following components:
the master-slave control mechanism is used for sending a calling request to other nearby direct-current emergency power supplies in an unoccupied state when the received predicted driving power is larger than the residual supply power of the direct-current emergency power supplies so as to control the other direct-current emergency power supplies sent with the calling request to be switched from the unoccupied state to the occupied state;
By way of example, the model and capacity of other dc emergency power sources in the unoccupied state nearby may be the same as or different from the model and capacity of the dc emergency power source built into the fire truck;
when a plurality of other direct current emergency power supplies are nearby in an unoccupied state, the other direct current emergency power supplies with the same model and capacity as those of the direct current emergency power supplies built in the fire-fighting vehicle are preferentially considered to be used for sending calling requests to the direct current emergency power supplies;
the direct-current emergency power supply is positioned on a fire-fighting vehicle for performing fire extinguishment and is connected with the master-slave control mechanism and is used for providing driving power for a driving mechanism of a water spray faucet of the fire-fighting vehicle;
the infrared shooting mechanism is arranged on a power supply box body for packaging the direct-current emergency power supply and is used for starting infrared shooting operation on a fire-fighting scene when receiving a first trigger instruction so as to obtain a corresponding real-time infrared picture;
for example, when the infrared camera shooting mechanism receives the first trigger instruction, each real-time infrared picture corresponding to each acquisition time can be acquired at a set frame rate in a uniform and time-sharing manner;

For example, the first authentication device, the second authentication device, and the range measurement device may be implemented using ASIC chips of different models;
the larger the area percentage of the smoke imaging area occupying the real-time infrared picture is, the higher the value of the determined corresponding fire extinguishing power range is;
for example, when the percentage of the area occupied by the smoke imaging area is 50% of the real-time infrared image, since the imaging field of view occupied by the real-time infrared image is fixed, the diffuse area of the solid smoke corresponding to the smoke imaging area can be determined based on the percentage of the area occupied by the smoke imaging area, and further the corresponding fire extinguishing power range is determined to be 800 kilowatts-1200 kilowatts based on the diffuse area of the solid smoke, and the maximum output power of a direct current emergency power supply in a fire-fighting vehicle for performing fire extinguishing is 600 kilowatts, therefore, the direct current emergency power supply needs to be sought to compensate for the additional 200 kilowatts-600 kilowatts;
for example, when the percentage of the area occupied by the smoke imaging area is 20% of the real-time infrared image, since the imaging view occupied by the real-time infrared image is fixed, the diffuse area of the solid smoke corresponding to the smoke imaging area can be determined based on the percentage of the area occupied by the smoke imaging area, and further the corresponding fire extinguishing power range is determined to be 200 kilowatts-500 kilowatts based on the diffuse area of the solid smoke, and the maximum output power of the direct current emergency power supply in the fire-fighting vehicle for performing fire extinguishing is 600 kilowatts, therefore, the full fire extinguishing of the fire extinguishing scene can be completed without searching for the direct current emergency power supply in the fire-fighting vehicle for performing fire extinguishing;
The direct current emergency power supply corresponding to the infrared shooting mechanism is used as a main power supply device, and other direct current emergency power supplies are used as auxiliary power supply devices of the direct current emergency power supplies corresponding to the infrared shooting mechanism so as to be started when the direct current emergency power supplies corresponding to the infrared shooting mechanism consume power;
wherein, other nearby direct current emergency power supplies in unoccupied state are located on nearby fire-fighting vehicles which are not started or in nearby standby equipment libraries;
the method for determining the predicted driving power based on the number proportion occupied by the red pixel points in the smoke imaging area comprises the following steps: a nonlinear function is adopted to represent a nonlinear mapping relation from the number proportion occupied by red pixel points in the smoke imaging area to the determined corresponding predicted driving power;
the nonlinear function is a function in which the relationship between the dependent variable and the independent variable is not linear, for example, the dependent variable is X, the independent variable is Y, the relationship curve of X and Y on the coordinate axis is not a straight line, and the specifically adopted formula may be y=a·x+b, where a and b are constants;
The method for determining the predicted driving power based on the number proportion occupied by the red pixel points in the smoke imaging area comprises the following steps: the red pixel point is a pixel point with an R channel value, that is, a red channel value exceeding a preset channel value threshold and being less than or equal to 255 in the RGB color space.
