The monitoring method of the refrigeration house provided by the embodiment of the application can be applied to a monitoring system of the refrigeration house, and the monitoring system can be carried on various hardware devices, such as a computer, a mobile phone, a tablet and the like, which can support the equipment carrying the monitoring system. Or to a monitoring device of a cold store, which is installed outside the cold store or in a protected area inside the cold store.
Based on the application scenario, please refer to fig. 1, which is a flowchart of a monitoring method of a refrigerator provided in an embodiment of the present application, the monitoring method includes:
step 101: and acquiring a plurality of monitoring pictures acquired by the camera. The camera is installed at the preset position in the cold storage, and the plurality of monitoring pictures correspond to different monitoring times.
Step 102: and determining whether the locked personnel exist in the cold storage according to the plurality of monitoring pictures and different monitoring times.
Step 103: and if the locked personnel are determined to be in the cold storage, early warning is carried out according to a preset safety early warning strategy.
In this application embodiment, the camera is installed to the preset position department in the freezer, and the monitoring picture and the monitoring time analysis that correspond that gather through the camera whether have the personnel that are locked, when confirming that there is the personnel that are locked, carries out the early warning according to predetermined safety precaution strategy. Compared with the prior art, the cold storage is not required to be checked manually at fixed time, so that the labor is saved; whether the person to be locked exists or not is determined according to the monitoring picture and the corresponding monitoring time, so that whether the person to be locked exists in the cold storage can be accurately judged; when the person to be locked is detected, early warning is carried out in real time, and then the user can save the person to be locked according to the early warning. Therefore, the method improves the real-time performance of monitoring the refrigeration storage and the safety of the refrigeration storage.
The detailed implementation flow of steps 101 to 103 will be described next.
In step 101, the camera is installed at a preset position of the refrigerator, and for the preset position, the position of the refrigerator door and the front area of the refrigerator door is included in the shot monitoring picture. For the camera, a fixed angle camera may be used, for example: and adjusting the camera to a better monitoring angle according to the position of the camera in the cold storage and the area corresponding to the monitoring picture to be collected, fixing the camera, and then collecting the monitoring picture in real time.
In addition, the temperature in the freezer is lower, in order to guarantee that the camera can last and stable work, can set up protection device for the camera, for example camera protective sheath, safety cover etc..
For the camera, after the camera is started, monitoring pictures are collected in real time, and each monitoring picture corresponds to one monitoring time. There may be different ways of determining the monitoring time, for example: when the camera shoots the monitoring pictures, the monitoring time corresponding to each monitoring picture is automatically generated, and then the monitoring pictures and the monitoring time are sent to a monitoring system or monitoring equipment. Or: when the camera shoots the monitoring picture, the monitoring time corresponding to each monitoring picture cannot be generated, but each time one monitoring picture is shot, the monitoring picture is sent to a monitoring system or monitoring equipment, and the monitoring system or the monitoring equipment takes the time of receiving the monitoring picture as the monitoring time corresponding to the monitoring picture.
Further, after the monitoring screen is acquired in step 101, step 102 is executed to determine whether there is a locked person in the cold storage according to the plurality of monitoring screens and different monitoring times. As an alternative embodiment, step 102 includes: marking the cold storage door regions in a plurality of monitoring pictures; detecting human-shaped areas in a plurality of monitoring pictures; determining the moving track and the moving direction of the personnel entering the refrigeration house according to the door area and the humanoid area of the refrigeration house; and determining whether locked personnel exist in the cold storage according to the movement track, the movement direction and different monitoring time.
In this embodiment, when labeling the cold storage door regions in the multiple monitoring frames, if the camera is at a fixed shooting angle, the regions of the cold storage door in the monitoring frames are also fixed, and then the labeling process may include: and marking the same preset area in each monitoring picture as a cold storage door area. The preset area is an area where the cold storage door is located in a monitoring picture obtained according to the shooting angle of the camera.
In the embodiment of the application, when the refrigeration storage door region is marked, a region can be preset in the monitoring picture as a fixed refrigeration storage door region, and then quick and accurate marking is realized.
Of course, if the camera does not adopt a fixed shooting angle, such as the camera is rotatable, the cold storage door area may not be fixed in the monitoring picture. In this case, the labeling of the cold storage door region can be realized by a neural network model (predictive model). The implementation process can include: collecting a large number of samples of monitoring pictures (at different shooting angles), manually marking the cold storage door regions in the samples, training a neural network model based on the marked samples after marking the samples, and using the trained neural network model for the cold storage door region marking in the step 102. The neural network model may be a Back Propagation (BP) neural network model, and the like.
Furthermore, after the refrigeration house door area is marked, when the human-shaped area in the monitoring picture is detected, the human-shaped area can be also detected through a neural network model. The specific implementation process is similar to that of the cold storage door region, and can comprise the following steps: collecting a large number of samples of monitoring pictures (including human monitoring pictures), manually labeling the human outlines or human positions in the samples, training a neural network model based on the labeled samples after labeling the samples, and using the trained neural network model for labeling the human-shaped area in step 102. The neural network model may be a Back Propagation (BP) neural network model, and the like.
And further, after the cold storage door region and the human-shaped region are determined, determining the motion track and the motion direction of the personnel entering the cold storage according to the cold storage door region, the human-shaped region and different monitoring times. Wherein, the motion track can be understood as the motion track of the entering person in the refrigeration house; the direction of movement is understood to mean in which direction the entering person moves in the freezer.
For the determination of the activity track, the human-shaped areas in each monitoring picture can be matched and connected to form a series of tracks of the movement of people, and the basis for matching and connecting can be the monitoring time. And determining the moving direction by combining the positions of different human-shaped areas relative to the cold storage door area, the determined moving track and the monitoring time. For example: the position of a human-shaped area in a monitoring picture of monitoring time 1 is A; the position of the human-shaped area in the monitoring picture in the monitoring time 2 is B; the position of the human-shaped area in the monitoring picture in the monitoring time 3 is C; the sequence of monitoring time 1, monitoring time 2 and monitoring time 3 from first to last is: monitoring time 1, monitoring time 2 and monitoring time 3; and position A is regional nearest apart from freezer storehouse door, and position B is regional nearer apart from freezer storehouse door, and position C is regional farthest apart from freezer storehouse door, and the movable track who finally determines then can be: a trajectory from position a to position B and then from position B to position C. Considering the sequence of monitoring time and the size of the different positions from the cold storage door region, the moving direction can be determined as follows: away from the direction of the cold storage door. The moving direction and the moving track are combined, the fact that the entering person moves in the refrigeration house within the period from the monitoring time 1 to the monitoring time 3 can be determined, and the direction is far away from the door of the refrigeration house, so that the entering person is not out.
Further, after the activity direction and the activity track are determined, whether locked people exist in the cold storage can be determined according to the activity track, the activity direction and different monitoring times, and as an optional implementation mode, the implementation process comprises the following steps: determining the entering time of the personnel entering the refrigeration house according to the moving track, the moving direction and different monitoring times; determining whether the person entering the refrigeration house has leaving time or not according to the movement track, the movement direction and different monitoring times; if the person entering the refrigeration house is determined not to have the leaving time, determining the staying time of the person entering the refrigeration house according to the entering time and the current time; and determining whether the person to be locked exists in the refrigeration house or not according to the residence time and a preset time threshold.
In such an embodiment, the process of determining the entry time may include: determining a corresponding monitoring picture when a person entering the refrigeration house enters the refrigeration house according to the motion track and the motion direction; and determining the monitoring time corresponding to the corresponding monitoring picture as the entering time when the refrigerator enters.
Understandably, when the entering time is determined, the moving direction comprises the direction towards the inside of the refrigeration house and the direction towards the door of the refrigeration house, and the moving track comprises the moving towards the inside of the refrigeration house and the moving towards the door of the refrigeration house, so that the moving track towards the inside of the refrigeration house is the track entering the refrigeration house, and the moving track towards the door of the refrigeration house is the track leaving the refrigeration house. And combining the monitoring time, wherein the monitoring time of the monitoring picture corresponding to the first position in the moving track facing the interior of the refrigeration house is the entering time. Of course, the monitoring time of the monitoring picture corresponding to the last position in the activity track towards the warehouse door is the leaving time.
In the embodiment of the application, when the entering time is determined, the corresponding monitoring picture can be determined by the activity track and the activity direction when the refrigerator is entered, and then the monitoring time corresponding to the monitoring picture is taken as the entering time, so that the determined entering time is more accurate.
Further, there may be a variety of situations when determining whether there is a departure time. For example: in the first case, in the activity track and the activity direction, there is no activity track at all toward the cold storage door, and it can be determined that there is no departure time. In the second case, there is an activity track toward the door in the activity track and the activity direction, but the last person position point in the activity track toward the door does not coincide with the door, and it can be determined that there is no leaving time because the person is not going out although the person is moving toward the door. In the third case, in the movement track and the movement direction, there is a movement track toward the cold storage door, and the last person position point in the movement track toward the cold storage door also coincides with the cold storage door, but it may be that a person tries to open the door, but fails to open the door, and then stays at the position of the cold storage door. Because if personnel stop in cold storage door department all the time, the camera can monitor the same monitoring picture, corresponds different monitoring time. Whether the last personnel position points in the moving track are the same position points or not can be detected, and if the personnel position points are the same position points, the leaving time can be determined to be not present; if not, it can be determined that there is a departure time.
Further, if it is determined that there is no departure time, calculating the stay time of the person according to the current time and the entrance time may include: and calculating the difference between the current time and the entering time, wherein the difference is the staying time. Wherein, confirm whether have the personnel that are locked in the freezer according to dwell time and predetermined time threshold, can include: and if the residence time is less than the time threshold, determining that the personnel are not locked in the cold storage, and if the residence time is more than the time threshold, determining that the personnel are locked in the cold storage. The time threshold may be set according to actual conditions, and a more appropriate value may be set in consideration of situations such as that a person may autonomously initiate a distress call and the physical endurance of the person, for example, 5 minutes or 3 minutes.
In the embodiment of the application, when determining whether the person to be locked exists, the entering time and the leaving time of the person entering the refrigeration house can be determined according to the moving track, the moving direction and the monitoring time, if the person does not leave the refrigeration house, the person entering the refrigeration house can be locked, the staying time can be calculated, and then whether the person to be locked exists in the refrigeration house or not can be determined according to the preset time threshold. Through this kind of mode, can confirm fast and accurately whether have the personnel that are locked, improve the security of freezer.
Further, after step 102, if it is determined that there are no locked people, it is indicated that everything in the cold store is normal, and no early warning is performed. If the locked person is determined, step 103 is executed, and early warning is performed according to a preset safety early warning policy, as an optional implementation, step 103 includes: and generating prompt information for representing the locked personnel in the cold storage, and feeding the prompt information back to the management end of the cold storage.
In this embodiment, the prompting message may be in the form of text, voice, or pictures. The management terminal of the refrigeration house can be a monitoring terminal of the refrigeration house, and has different forms, such as: computers, cell phones, etc. Based on different forms of the prompt message and different forms of the management terminal, the feedback form may be various, for example, sending the message to the management terminal; telephone the management terminal, etc.
In the embodiment of the application, when early warning is carried out, prompt information used for representing personnel locked in the refrigeration house can be generated and fed back to the management end of the refrigeration house, so that a user at the management end of the refrigeration house can carry out corresponding treatment, and the safety of the refrigeration house is improved.
In addition to this embodiment, an alarm device may be installed in/out of the refrigerator, and in this case, step 103 may include: and sending a starting instruction to the alarm device to start the alarm device to alarm. The alarm device may be: various sound/light type alarm devices such as buzzers, alarm lamps.
In addition, the two implementation modes can be executed simultaneously, on one hand, prompt information is sent to the management end, on the other hand, the alarm device is started to give an alarm, and the early warning effect is improved, so that a user can rescue locked personnel as soon as possible.
In this embodiment of the present application, before step 103, the method may further include: starting a temperature detection device installed in a cold storage; receiving temperatures of a plurality of areas in the refrigerator detected by the temperature detection device; and determining whether early warning is needed according to the temperatures of the plurality of areas.
