Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

Referring to fig. 1 and 2, the embodiment provides an anti-theft intelligent fire-fighting cabinet used in an electric charging field, which includes a cabinet body 1, a vehicle type identification driving device, a fire detection device 2, an anti-theft door opening device, a monitoring device and a controller.

The cabinet body 1 is a main body of the fire-fighting cabinet, and comprises a cabinet door 11, a shell 12 and an electromagnetic device. The cabinet door 11 is movably mounted on the housing 12 and encloses an outer area with the housing 12. The combined structure of the cabinet door 11 and the casing 12 can adopt the cabinet body structure of the existing fire-fighting cabinet, the cabinet door 11 can be connected with the casing 12 by adopting a hinge and the like, one of the casings 12 is provided with an opening, and the cabinet door 11 can move to cover the opening. The electromagnetic device is used to open or close the cabinet door 11, and in this embodiment, the electromagnetic device includes an electromagnetic lock. An electromagnetic lock is installed on the housing 12 and is used to open or close the cabinet door 11. The electromagnetic lock utilizes the principle of electromagnetism, can produce powerful suction when the electric current passes through the silicon steel sheet and tightly hold the effect that adsorbs iron plate and reach the lock door.

In the embodiment, the types of parked vehicles are classified into electric vehicles and non-electric vehicles, and the non-electric vehicles are generally fuel vehicles, because most of the current motor vehicles mainly use the fuel vehicles, while the number of the electric vehicles is not large, and because the number of parking spaces is effective, the fuel vehicles occupy the parking spaces of the electric vehicles. Therefore, the present embodiment is provided with the vehicle type recognition driving-away device, and the vehicle type recognition driving-away device is installed on the cabinet body 1. In practice, the cabinet 1 is placed around a parking space. And the vehicle type identification driving device comprises a first image acquisition module, a bottom line covering judgment module, a position profile acquisition module, a second image acquisition module, an extraction module, an identification module, a vehicle type judgment module, a driving module and a charging module.

Referring to fig. 3, the first image capturing module is used for capturing the bottom line image of each parking space in real time. The visible light camera is used for shooting the parking space bottom line of the parking space so as to obtain a bottom line image. The visible light camera can be installed in the front side or the rear side of parking the vehicle through mounting structures such as mounting posts, bases and the like, certainly, on some special parking spaces, the visible light camera can also be arranged on the left side or the right side of the parking space, for example, the parking space is a lateral parking space, and then the visible light camera can be arranged in the lateral direction.

The bottom line covering judging module is used for judging whether the parking space bottom line in the bottom line image is covered by the parked vehicle. Because the parking stall bottom line is complete when the vehicle is not parked, and when the parked vehicle is parked on the parking stall, the parking stall bottom line can be covered by the parked vehicle, so that the parking stall bottom line can not be found in the bottom line image, and the parking stall can be judged to be occupied by the vehicle.

The position contour acquisition module is used for acquiring vehicle position information and contour images of the parked vehicles when the parking space bottom lines are covered by the parked vehicles. When a parked vehicle occupies a parking space, the geomagnetic sensor can be used for detecting vehicle information, the geomagnetic sensor utilizes the characteristic determined by the distribution of the earth magnetic field, the magnetic field distribution can be changed when the vehicle passes through, the basic principle that the resistance characteristic inside the sensor can be changed is used for measuring the magnetic field change, and the vehicle position information can be acquired at the moment. Compared with a common geomagnetic coil detector, the geomagnetic sensor has the advantages of small installation size, high sensitivity, small construction amount, long service life and small damage to the road surface. Generally speaking, the geomagnetic sensor itself may be equipped with a camera function, so as to directly acquire the profile image of the parked vehicle, and of course, other cameras may be used to acquire the profile image of the vehicle.

The second image acquisition module is used for acquiring infrared images within the outline range at the position of the vehicle according to the position of the vehicle and the outline images. In this embodiment, the second image capturing module includes an infrared camera, and the infrared camera is configured to perform infrared shooting on an area within a contour range at the vehicle position to obtain an infrared image. In the previous module, since the position and contour of the parked vehicle have been determined, the infrared camera takes infrared images of the area within the contour at the vehicle position to obtain infrared images. The infrared camera can adopt the existing infrared camera equipment, and can gather the infrared image in a certain range, utilize the different corresponding infrared image of formation of thermal radiation.

The extraction module is used for extracting the heating position in the infrared image and the heating characteristic of the heating position. When the parked vehicle is just parked on a parking space, the heating positions of the fuel vehicle are generally an engine compartment and a tail gas area of the vehicle, namely an engine hood part and a tail gas pipe at the front part of the vehicle body, the heat of the part is concentrated, and a strong contrast effect is formed by the heating states of the part and other parts of the vehicle body. The electric automobile is powered by electricity, the heating area of the electric automobile is generally the whole automobile body, and even if the heating value of part of the area is larger, the heating value is not larger than that of the fuel automobile.

The identification module is used for identifying the parked vehicle in a preset vehicle identification system according to the heating position and the heating characteristic so as to obtain the vehicle type of the parked vehicle. The heating position and the heating characteristic correspond to a unique vehicle type in a preset vehicle identification system. In the preset vehicle recognition system, two different vehicle recognition modes are preset. One of the vehicle identification modes is used to identify a parked vehicle whose heat generation place is the entire region of the parked vehicle as an electric vehicle, and the other vehicle identification mode is used to identify a parked vehicle whose heat generation place is the engine compartment region of the parked vehicle as a non-electric vehicle.

Generally, the heating positions of the fuel vehicle and the electric vehicle are different, and if the heating positions are the same, the heating characteristics are necessarily different. For the heating characteristic, the fuel vehicle adopts a fuel engine, so that the heating value is very large, and the shape of a heating area is relatively fixed. The area where the electric automobile generates heat is generally the storage battery and the engine, the heat productivity is obviously smaller than that of the fuel engine, and meanwhile, the heating area is different. Here, it can be verified that if the heat of the engine or the storage battery of the electric motor can reach the heat of the fuel engine, the fuel engine uses the fuel to compress air to do work, the temperature can reach the ignition point, if the temperature occurs in the electric automobile, the cable of the electric automobile is inevitably in fire, which is not normal, and therefore the local heat of the electric motor cannot reach the heat of the fuel automobile.

The vehicle type judging module is used for judging whether the vehicle type is an electric vehicle. The type of the vehicle can be determined by the former module through the heating position and the heating characteristic, so that whether the parked vehicle is an electric vehicle or not can be judged in the module, and corresponding treatment can be conveniently carried out subsequently.

The driving-away module is used for driving away the parked vehicle when the type of the vehicle is a non-electric vehicle. Because non-electric automobile occupies the parking stall and can lead to filling the charging resource of electric pile to be wasted, also make some electric automobile not have the parking stall to charge simultaneously, consequently need drive away non-electric automobile. When driving away, the parked vehicles can be driven away through the ground lock, the barrier gate and the sound and light alarm system, and alarm information is sent to the corresponding management platform. Of course, also can send out warning sound through the attention device of setting in charging the stake, remind the driver who parks the vehicle to move the vehicle away. Like this, on the one hand can guarantee that the resource of charging station is by make full use of, on the other hand makes things convenient for electric automobile to charge, but also can guide green vehicle's selection, and then can play the effect of environmental protection deeply.

The charging module is used for charging the parked vehicle when the vehicle type is an electric vehicle. This module can directly be predetermine in the electric pile that fills on parking stall, when judging that the vehicle type is electric automobile, fills the direct function of charging that realizes parking the vehicle of electric pile.

The fire detection device 2 is installed in an outer region of the cabinet 1 and serves to detect whether a fire is generated in the outer region. In the present embodiment, the fire detection device 2 includes a smoke fire detector 21 and a temperature-sensitive fire detector 22, and may include the smoke fire detector 21 or the temperature-sensitive fire detector 22. The smoke fire detector 21 is installed in the outer region and serves to detect whether fire smoke is generated in the outer region. The temperature sensitive fire detector 22 is installed in the outer region and serves to detect a real-time temperature of the outer region and generate a fire signal when the real-time temperature exceeds a preset temperature. The two detectors can detect relevant information of the fire through smoke and temperature generated by the fire, so that the fire is detected. Of course, in other embodiments, the fire detection device 2 may include other detectors, such as a flame detector, which can accurately detect the fire signature and generate a fire occurrence signal.

The anti-theft door opening device comprises a trigger module and an alarm module. The trigger module is installed on the outer wall of the cabinet body 1 and is used for emergency personnel located outside the cabinet body 1 to generate a trigger signal so as to drive the electromagnetic device to open the cabinet door 11.

The embodiment provides an anti-theft intelligent fire-fighting cabinet used in an electric charging place, and the fire-fighting cabinet refines an identification module on the basis of the embodiment 1. The identification module comprises a characteristic acquisition unit, a gray difference calculation unit and a vehicle type judgment unit.

The characteristic acquisition unit is used for acquiring a background gray value and a brightest gray value in the infrared image and taking the background gray value and the brightest gray value as heating characteristics. The background gray value is a region with stable temperature in the parked vehicle, such as a vehicle frame, and the brightest gray value is a region with the largest heat generation amount of the vehicle, and is also a region with the strongest heat generation amount, such as a fuel cabin of a fuel vehicle.

The gray difference calculating unit is used for calculating the gray difference value between the brightest gray value and the background gray value. The grey scale difference value actually reflects the temperature difference in the parked vehicle, i.e., the temperature difference between the hottest zone and the average temperature. During calculation, the brightest gray value is generally the gray value of a dark color area in the infrared image, and the value with the largest gray value can be selected, while the background gray value is the gray value of a light color area, and the gray value with the largest area occupied by the same color can be selected.

The vehicle type judging unit is used for judging whether the gray difference value is larger than a preset gray value I, if so, the vehicle type is judged to be a non-electric vehicle, and if not, the vehicle type is judged to be an electric vehicle. And comparing the gray difference value with the preset gray value one, so that the type of the vehicle can be accurately judged according to the gray information. In fact, the principle used in the present unit is to identify the parked vehicle on the basis of the difference between the maximum temperature in the fuel vehicle and the maximum temperature in the electric vehicle. When the gray difference value is larger than the preset gray value, the temperature difference is very large, and the parked vehicle can be judged to be not the electric vehicle. For the determination of the preset gray value one, the heating conditions of various electric vehicles can be integrated for setting, and meanwhile, the electric vehicle with the largest heating value and the fuel vehicle with the smallest heating value are selected as two limit conditions in consideration of the heating condition of the fuel vehicle, so as to determine the specific numerical value of the preset gray value one. For example, the maximum temperature that the electric vehicle can generate is 75 degrees celsius, and the minimum temperature that the fuel vehicle can generate is 400 degrees celsius, then the temperature corresponding to the preset gray value one may be selected from the range of 75 degrees celsius to 400 degrees celsius, and an intermediate value is selected as far as possible. Therefore, the method in the embodiment can judge the vehicle type by utilizing the heating characteristics of the vehicle so as to facilitate the subsequent driving-away treatment of the non-motor vehicle, and the recognition rate of the vehicle type can be obviously improved because the fuel engine and the electric engine have great difference in the aspect of heat generation.

In general, the driving location area and the passenger location area in the parked vehicle are determined, and thus the areas in the infrared image can be directly selected at the time of acquisition. In both areas there are usually people located when the vehicle is just parked, and this step is to screen out the two people-occupied areas.

The noise judgment unit is used for judging whether the gray value of the driving position area or the passenger position area reaches a preset human body infrared gray value. The preset human body infrared gray value is consistent with the gray value corresponding to the human body temperature, a vehicle can be parked on a parking space in advance during specific setting, meanwhile, the infrared features of people in the vehicle are extracted, the infrared gray value related to the body temperature is obtained, and the value is used as the preset human body infrared gray value.

The noise removing unit is used for removing the part of the gray value larger than the preset human body infrared gray value from the infrared image when the gray value reaches the preset human body infrared gray value. Therefore, factors influencing the gray level judgment can be eliminated, factors with larger gray level values in the vehicle do not exist correspondingly, the obtained heating characteristics are closer to the actual heating characteristics of the vehicle, and the accuracy of data extraction is improved.
