Preferably, the intelligent terminal unit comprises a mobile phone, a computer and an iPad. The intelligent terminal unit can be connected with a wireless network, and a series of functions including remote call response, remote visual intercom, remote monitoring, remote door opening and the like are realized through the set APP;
specifically, the outdoor host unit and the processing and transmitting unit can be arranged into an integral structure, are arranged outside the door and are powered by the first power supply unit; the first power supply unit is arranged outside the door and respectively supplies power to the outdoor main machine unit and the processing transmission unit.
Preferably, the sound output module of the indoor extension unit can also be used for broadcasting time, temperature, humidity and other data. The sound output module may be implemented by an audio speaker.
Preferably, the outdoor main unit further comprises a human body sensing module for sensing whether a person is outside the door;
the intelligent terminal unit further comprises an outdoor monitoring module and an alarm snapshot module, and the outdoor monitoring module controls the alarm snapshot module to monitor the outdoor environment.
The human body induction module is used for inducing whether a person is outside a door or not, then information of the detected person is transmitted to the intelligent terminal unit, the outdoor monitoring module controls the alarm snapshot module to shoot, photo information is stored, and a user is reminded of visiting guests.
The following two cases are specifically distinguished:
in the first situation, if the visitor comes before, the outdoor monitoring module controls the alarm snapshot module to snapshot the image of the visitor when the visitor comes for the first time and stores the image, then the visitor visits again, the outdoor monitoring module compares the snapshot image with the image stored in advance through the alarm snapshot module, if the comparison is successful, the relevant information of the visitor is directly sent to the intelligent terminal module, and the user of the intelligent terminal module directly knows which visitor comes.
In the second situation, if the visitor is the first visitor, the outdoor monitoring module controls the alarm snapshot module to store the snapshot image of the visitor and store the snapshot image on the cloud server, in addition, if the visitor is a thief or other illegal person, the intelligent terminal module obtains the information of the thief or other illegal person who is put on the network through the network and matches the information with the image obtained by the alarm snapshot module, and if the matching is successful, the intelligent terminal module gives an alarm. The outdoor monitoring is realized through the two modes.
The image captured by the alarm capturing module can be affected by the external environment, so that the image is not clear enough, and the collected image has no reference value, so that the definition processing of the image under different conditions is necessary, for example, the definition of the image during capturing at night can be affected. Therefore, for nighttime image enhancement, the following description is made:
if a frame-based brightness fusion algorithm is adopted, the brightness at night is L N Brightness L of the background at night NB When the brightness of (b) is similar (no moving object appears, i.e. the background brightness is similar), the enhanced brightness L ENH Close to daytime background luminance L DB Since the brightness of the background in the daytime is multiplied by the brightness of the background at night as a result of the enhancement, if there is no moving object in the background region, the enhancement effect is very good, and no brightness information is lost. Relative daytime background luminance L DB Smaller L NB Enhanced luminance L ENH The larger the value (due to the luminance ratio) is, e.g. for an 8-bit luminance image, the luminance value is much larger than 255, the larger the relative daytime background luminance is, L DB L of NB Enhanced luminance L ENH The smaller the value, the less the enhancement effect is obtained.
The night video frame brightness algorithm by adding Term is provided based on the method, and the formula is provided as follows:
L ENH (x,y)＝L N +w f (x,y)*(L DB -L NB )
wherein w f (x, y) shows the weight of enhancement, and the setting range is [0,1 ]]，w f (x,y)*(L DB -L NB ) Denoted Term.
In the following description of the process of weight setting, the enhancement Term is based on the difference L between the daytime background brightness and the nighttime background brightness DB -L NB I.e. the luminance Term of the night video frame should be enhanced the larger the difference between the daytime luminance value and the night luminance value. If the luminance at night L N Closer to the background luminance L at night NB Setting a weight coefficient w f (x, y) is close to 1. In order to solve the problem that the inconsistent proportion causes excessive brightness of the foreground, the day is usedBackground and night background to enhance the night video frame brightness, the formula for the weighting factor w (x, y) is given below:
where T represents a threshold, T is set to 30 in the present invention. The enhanced Term based on the analysis may be non-negative, so absolute values are used. When the brightness of the partial areas in the night video frame image is greater than that of the daytime background, the areas do not need to be enhanced, and only the brightness values of the night areas need to be maintained. With this arrangement, the following problems can be solved: (1) the problem of light closing is solved, the brightness of a door lamp at an outdoor doorway can be effectively protected, and the definition of an image is further ensured; (2) if the luminance of the night frame is L N Brightness L of the background at night NB When the phase difference is larger than the threshold value, the pixel areas are considered as foreground object moving objects. If the brightness of the foreground object is completely different from the daytime background or the nighttime background (e.g., the brightness of the moving object itself), the weighting factor is set to 0 so that the enhanced brightness will not be affected by the background brightness.
The other aspect influencing the definition of the image is a dark area in the image, the definition of the image can be directly influenced due to too dark light, and the definition of the image can be improved in a mode of enhancing the dark area; those dark areas cannot be enhanced if conventional enhancement algorithms such as power-transfer enhancement are used, if the night frame luminance L N (x, y) and L NB The larger the difference of (x, y) values, the more foreground moving objects are set, and the proposed equation makes the smaller the weight, the less L will be reduced DB And L NB The influence of (c).
Therefore, in order to reduce the problems caused by different luminance ratios in the snap shot image, reduce the difference between the confusion pattern and the guard boundary, the moving object boundary should have more natural harmonious transitions. In the invention, the image is excessively enhanced by adopting the following method, a target moving object of a foreground is extracted to obtain a binary image M (x, y) of a foreground target, a Gaussian low-pass filter of 3x3 is adopted for the binary image M (x, y) of a moving object region to smooth a boundary, w' (x, y) represents the weight of the filter, and the final brightness weight w (x, y) is obtained as follows:
therefore, the image after smoothing processing is clearer, and the clear image can be obtained through the alarm snapshot module under the condition that the light intensity is weak at night.
Preferably, the human body sensing module is an infrared sensor.
Whether someone is outside the door or not is detected through the infrared sensor, the infrared sensor is a sensor which takes infrared rays as a medium to complete a measuring function, has the advantages of high response speed and the like, is small in size, low in price and convenient to install, and is suitable for being installed in an outdoor host unit outside the door.
When the human body induction module detects whether people are outside the door or not, whether the target object outside the door is a person or not is distinguished, and if the target object is a large animal or other objects, information detected by the human body induction module is wrong and false alarm is caused, so that based on the problems, the invention adopts two classification devices, wherein the former is an Adaboost-based tree-shaped classifier which has 4 layers in total, and the classifier has a simple structure and few layers and can achieve very high detection rate and considerable false alarm target rate. And then, a tree classifier based on CVM is adopted, the hierarchy of the classifier is determined by the final training result, and when all negative samples are used up or a certain number of layers is exceeded, the child nodes are not trained. This apparatus is used to maintain a high detection rate and minimize the false alarm target rate of the tree classifier of Adaboost, whose structure is shown in fig. 3.
In the structure, the number of layers of an Adaboost-based tree-like combined classifier at the upper layer is small, so that a high detection rate can be ensured, in the Adaboost, most negative samples need to be rapidly excluded, only a few negative samples enter the next layer, and the calculation cost of a CVM classifier at the next layer is higher than that of the Adaboost, so that the average detection time of the negative samples can be controlled to be a small value.
The classifier is trained by adopting 1000 positive samples and a mass of negative samples on a database acquired by a project group, the negative samples are found in an Adaboost-based tree classifier on an upper layer by adopting a mode of randomly extracting the negative samples, for a non-balanced CVM-based tree classifier on a lower layer, a punishment factor of the positive samples is 10 times that of the negative samples, the positive samples are randomly extracted firstly, then clustering is carried out in a randomly extracted result, all the negative samples are divided into a plurality of samples, and then a class of samples with the highest occurrence probability is selected to serve as the negative samples used for training.
The detection rate of the trained classifier reaches 89.1% for 1000 positive samples in the test set, and the false alarm rate is only 0.015% for more than 50000 negative sample test sets.
By adopting the method to detect the target, whether people or other objects stand outdoors can be effectively and quickly detected, and the detection accuracy is improved.
Specifically, the first battery unit is a dry cell or a rechargeable battery, and the second battery unit is a dry cell or a rechargeable battery.
The dry battery is convenient to use, practical and convenient to replace, the rechargeable battery is energy-saving and environment-friendly, and can be selected according to specific requirements.
The dry cell is a zinc-manganese cell, also called a carbon-zinc cell.
The structure is as follows: the negative electrode is a cylinder made of zinc and is made into a cylinder shape for storing chemicals such as electrolyte. The positive electrode is a carbon rod surrounded by a mixture of manganese dioxide, carbon powder and ammonium chloride water, and is collectively called a "carbon pack". A paste composed of ammonium chloride, zinc chloride aqueous solution and starch is filled between the carbon bag and the zinc cylinder to form the electric paste. The battery mouth is sealed by a sealing agent prepared from asphalt, rosin and the like.
The zinc cylinder, carbon bag and ammonium chloride solution of dry cell are respectively equivalent to zinc sheet, copper sheet and dilute sulfuric acid solution of voltaic cell. When the dry battery works, the zinc and the ammonium chloride are changed to generate hydrogen which is attached to the carbon rod. Since hydrogen has a large resistance, a considerable voltage drop occurs near the electrode during operation of the battery, resulting in a decrease in the terminal voltage (a phenomenon called "polarization"). Therefore, manganese dioxide is added to dry batteries as a "depolarizer". Manganese dioxide is a poor conductor, and if too much manganese dioxide is used, the internal resistance of the battery is increased, and if too little manganese dioxide is used, the depolarization effect is too slow. In order to solve the problem, some carbon powder with better electric conductivity is usually added, and the carbon powder mainly plays a role of electric conduction and secondly absorbs part of gas generated in the reaction process.
The main component in the paste is ammonium chloride, which corresponds to the dilute sulfuric acid solution of the voltaic cell. The zinc chloride in the electric paste has the functions of increasing the concentration of zinc ions in the solution, alleviating the corrosion of the zinc chloride on the zinc cylinder and prolonging the service life of the battery.
The purpose of sealing is to prevent the inside moisture diffusion of battery and outside moisture invasion, avoid the electric liquid outflow to make the dry battery portable to and prevent carbon package and zinc section of thick bamboo short circuit.
The material composition of the dry cell is as follows:
a positive electrode material: mnO2 and graphite rods;
and (3) anode material: zinc sheets;
electrolyte: NH4Cl, znCl2 and starch paste;
the battery symbol may be expressed as:
(-) Zn | ZnCl2, NH4Cl (paste)/MnO 2| C (graphite) (+)
Negative electrode: zn = Zn2+ +2e;
and (3) positive electrode: 2MnO2+2NH4+ +2e = Mn2O3+2NH3+ H2O;
and (3) total reaction: zn +2MnO2+2NH4+ =2Zn2+ + Mn2O3+2NH3+ H2O.
The battery using graphene as a raw material can be used as the first battery unit and the second battery unit, the upper limit service temperature of the lithium ion battery can be increased by 10 ℃ due to the novel high-temperature resistant technology based on the graphene, the service life of the battery is 2 times that of a common lithium ion battery, the service life of the battery using the graphene as the raw material can be prolonged, and the intelligent doorbell is not required to be frequently changed.
The principle of the graphene-based lithium ion battery is that a high-temperature anti-decomposition additive is added into electrolyte and matched with a high-temperature stable large single crystal positive electrode, so that the thermal stability of the battery is greatly improved, and meanwhile, graphene is adopted for efficient heat dissipation. The technical breakthrough of the graphene-based high-temperature lithium ion battery mainly comes from three aspects:
1. adding special additives into the electrolyte to remove trace water and avoid high-temperature decomposition of the electrolyte;
2. the battery anode is made of a modified large single crystal ternary material, so that the thermal stability of the material is improved;
3. by adopting the novel material graphene, the efficient heat dissipation between the lithium ion battery and the environment can be realized.
The charge and discharge test in the high-temperature environment shows that the temperature rise of the graphene-based high-temperature lithium ion battery is reduced by 5 ℃ compared with that of a common lithium ion battery under the same working parameters; the capacity retention rate is still over 70 percent after 2000 times of high-temperature circulation at 60 ℃; the capacity loss is less than 13 percent when the product is stored for 200 days at the high temperature of 60 ℃.
Preferably, the indoor extension unit further comprises a time module, and the time module is connected with the internet and used for synchronously acquiring the current time.

Through this kind of mode, weather forecast data can be synchronous in real time, helps people know outdoor weather condition in real time, and reasonable increase and decrease clothes arrange the trip etc..
