[0050] Embodiment one

[0051] Figure 1 is a structural schematic diagram of the unattended alarm device of the substation provided by the third embodiment of the present application. Figure 1 As shown, it specifically includes the following steps:

[0052] The image acquisition module 101 includes a full-color camera or an infrared camera, and is used to acquire monitoring images around the substation.

[0053] The image recognition module 102 is configured to perform human body recognition on the monitoring image to determine personnel information included in the monitoring image.

[0054] The target personnel recognition module 103 is configured to filter the personnel information according to a preset rule to determine target personnel with specific human body characteristics.

[0055] The region recognition module 104 is configured to determine a region where the target personnel is located based on at least one frame of the monitoring image.

[0056] The dynamic tracking module 105 is configured to perform dynamic tracking on the target personnel based on at least two frames of the monitoring image to determine a direction in which the target personnel travels.

[0057] The monitoring module 106 is configured to generate a prompt information when the region determination module determines that the region where the target personnel is located is a target region, or determines that the direction in which the target personnel travels is towards the target region.

[0058] The prompt module 107 receives the prompt information and converts the prompt information into sound and light prompt information, and sends the sound and light prompt information.

[0059] First, the use scenario of the present application can be near a substation. Some non-working personnel such as children may mistakenly enter a dangerous area. In order to ensure the safety of personnel, a detection and safety prompting device can be provided. The device can be installed in a substation that can reasonably detect a dangerous area. If necessary, the alarm information will be transmitted to the corresponding department through the wireless transmission module.

[0060] Based on the above use scenario, it can be understood that the execution subject of the present application can be an intelligent electronic device integrated with the above-mentioned unattended alarm device of the substation, or a software running in the intelligent electronic device or a system established here. No further limitation is made here.

[0061] In the image acquisition 101, the full-color camera can be a monitoring camera that relies on its own hardware configuration to realize the acquisition of a color monitoring picture. Generally, the full-color camera mainly relies on a fill light. When the light is relatively dark, the white light is turned on to improve the illumination of the environment, so that the camera can present a color image at night. The infrared camera can be a camera equipped with a corresponding infrared fill light. The infrared camera is currently widely used, but the monitoring picture of the camera is black and white after the infrared light is turned on. If a color picture is needed, a white light / warm light fill light is needed. Generally, the infrared camera automatically starts through the infrared light at night to collect black and white images.

[0062] In the scheme, the substation is a substation and peripheral equipment of the substation, and the substation is a power facility for transforming voltage, receiving and distributing electric energy, controlling the flow direction of electric power and adjusting voltage in a power system, which connects power grids of various voltage levels through its transformer. There are many types of internal equipment in the substation, including transformer, switch, four small devices, and reactive device equipment, and other equipment and auxiliary devices, such as wave suppressor, insulator, high voltage sleeve, guide wire, grounding device, secondary equipment, and high voltage direct current equipment. The periphery of the substation is the area near the substation in the substation, which is usually dangerous and only allows professional personnel to enter.

[0063] The monitoring image can be a video or image file obtained by a full-color camera or an infrared camera.

[0064] In the scheme, the acquisition principle is to convert an optical image signal into an electrical signal. When the device captures an object, the light reflected on the object is collected by the camera lens, focused on the light receiving surface of the camera device, and then converted into electrical energy by the camera device to obtain a video signal, but the signal is very weak. It needs to be amplified by a preamplifier circuit, and then processed and adjusted by various circuits to obtain a standard signal that can be recorded on a recording medium such as a video recorder, or transmitted through a transmission system or displayed on a monitor.

[0065] The image acquisition module 101 uses a camera to acquire a monitoring image, and can identify the image content monitored, such as saving in a hard disk, burning on a DVD, or saving in a backup storage device, for use as archival data.

[0066] In the scheme, human body recognition is a process of detecting key points of a human body through images or videos. The main process of recognition should be to separate the target from the background, extract the overall contour of the person, and then use the BP (Back Propagation) neural network algorithm to perform feature recognition based on the feature library. In the scheme, personnel information should include face information, identity information, and work clothes for recognition and judgment.

[0067] In the image recognition module 102, the monitoring image acquired can be used to identify human body features based on a neural network model, and finally obtain personnel information, i.e. identity information of the person. For example, in the process of identifying an object, feature information is extracted, and then the feature information is compared with the information in the database to determine whether the object is a human body, and if it is a human body, further identity information is extracted.

[0068] The target personnel identification module 103 can use pre-set rules to identify whether the target data is a human body. If the target data is a human body, the target personnel identification module 103 further judges whether the target data is a worker. If the target data is not a worker, the target personnel identification module 103 determines that the target data is target personnel containing a specific human body feature. The human body feature is mainly determined by detecting whether the worker wears a work uniform. When the human body feature cannot identify the identity information, the target is classified as data to be screened, and subsequent tracking and shooting are performed.

[0069] In another possible embodiment, after a human body is identified, a human body feature is determined, for example, whether the height is below 1.4 meters. If yes, the target personnel containing the specific human body feature is determined. For example, a child enters the monitoring range. Through such a setting, the target personnel containing the specific human body feature can be used to monitor children, so as to avoid the risk of electric shock.

[0070] The target personnel identification module 103 identifies and screens the target data through pre-set screening rules. For example, whether the face is a worker is detected. If the face is not a worker, the target is selected. In addition, for the problem that the personnel are far away or the face is blurred, the work uniform can be used for identification. For example, the work uniform can be identified according to the corresponding color, style and special mark. If a non-worker is found, the next step is performed.

[0071] The region identification module 104 is a still picture collected at a certain moment in the monitoring video. For example, the frame rate of the camera is 25 frames per second. Therefore, 25 frames of images can be collected per second, and each frame of image is one of the 25 frames. The region is the position of the target personnel. The target personnel can be calculated by using coordinates to obtain the region of the target personnel. The specific position of the region can be obtained by establishing a coordinate system for the region of the target personnel through identification of one frame of image.

[0072] The dynamic tracking module 105 can use a two-frame subtraction method when an object moves in the monitoring scene. That is, there is a relatively obvious difference between frames. The absolute value of the brightness difference between two frames is obtained by subtracting the two frames. Whether the absolute value is greater than a threshold value is determined to analyze the motion characteristics of the video or image sequence, and whether the target personnel of the image is in a motion state is determined. For example, if the target personnel moves, the moving direction of the target personnel can be predicted by using a correlation function, and whether the target personnel moves to a dangerous region is calculated. The correlation function can be a pre-set function of the worker, or a Gaussian background difference method can be used. The specific implementation manner can be that when the two-frame subtraction method reflects a change, a filter is used to extract the difference information.

[0073] The monitoring module 106, the target area is a preset area array, each point in the array corresponds to a coordinate position. When the coordinates of the target person coincide with the target area coordinates, or through motion characteristic analysis it is concluded that it will move to the target area, a prompt information can be generated. The prompt information includes audio and warning lights, the purpose is to remind the target person to stay away from the area.

[0074] The prompt module 107 can convert digital signals into sound and light signals. Specifically, when the prompt information is sent, the existing audio file and light setting will be called to achieve the effect of early warning. For example, when someone breaks into the target area, the prompt module 107 will flash a red alarm light and play an alarm audio to remind the target person to evacuate quickly.

[0075] In combination with the above examples, in the process of prompting non-staff, the prompt method can be an alarm audio such as a buzzer alarm, and the light uses a red alarm light and flashes according to the frequency. In the process of prompting children, the prompt method can be to call a safety warning recorded in advance by human voice to remind the children to evacuate immediately, and the flashing frequency of the alarm light is relatively low. To avoid children being frightened and panicking during the pre-warning process, the alarm form should also be relatively mild.

[0076] In this scheme, optionally, the dynamic tracking module is further used for:

[0077] Determining the travel speed of the target person based on at least two monitoring images.

[0078] Correspondingly, the monitoring module generates a prompt information in the case that the identified travel direction of the target person is toward the target area, and the travel speed exceeds a set speed.

[0079] In this scheme, the displacement of the target person in two frames is obtained by subtracting the coordinates, and then the time value between the two frames is obtained. The travel speed of the target person is obtained by dividing the displacement by the time through the speed calculation formula. It is used to analyze whether the target person will reach the target area after a certain time.

[0080] In this scheme, considering that if the moving person moves too fast, he or she may have entered the target area before the warning is played. This has the advantage of early warning the target person to avoid accidents.

[0081] In the embodiment, an unattended alarm device of a transformer substation is invented, which comprises: an image acquisition module comprising a full-color camera and / or an infrared camera; an image recognition module for determining personnel information included in the monitoring image; a target personnel recognition module for determining target personnel with specific human characteristics; a region recognition module for determining the region where the target personnel is located based on at least one frame of monitoring image; a dynamic tracking module for determining the direction of travel of the target personnel; a monitoring module for generating prompt information; and a prompt module for issuing the sound and light prompt information. The safety reminding method for transformer substation equipment operation can identify personnel who intrude into a dangerous live region and give strong reminders and warnings to reduce the probability of electric shock accidents.

[0082] Embodiment two

[0083] Figure 2 Fig. 1 is a structural schematic diagram of an unattended alarm device of a transformer substation provided by the embodiment three of the present application.

[0084] As shown in Figure 2 , the method specifically comprises the following steps:

[0085] The image acquisition module 101 comprises a full-color camera and / or an infrared camera, and is used for acquiring monitoring images of the surroundings of the transformer substation.

[0086] The image recognition module 102 is used for human body recognition on the monitoring images to determine personnel information included in the monitoring images.

[0087] The target personnel recognition module 103 is used for screening the personnel information by using pre-set rules to determine target personnel with specific human characteristics.

[0088] The region recognition module 104 is used for determining the region where the target personnel is located based on at least one frame of monitoring image.

[0089] The dynamic tracking module 105 is used for dynamic tracking of the target personnel based on at least two frames of monitoring image to determine the direction of travel of the target personnel.

[0090] The monitoring module 106 is used for generating prompt information in the case where the region judgment module identifies that the region where the target personnel is located is a target region, or identifies that the direction of travel of the target personnel is toward the target region.

[0091] The prompt module 107 receives the prompt information and converts the prompt information into sound and light prompt information to issue the sound and light prompt information.

[0092] The intelligent alarm module 108 is configured to generate an alarm information when the area where the target person is located is the target area and the staying time reaches the set time, so as to send the alarm information to the substation monitoring end and the rescue end; wherein the alarm information comprises a monitoring image of the target person and a time when the target person enters the target area.

[0093] In the scheme, the intelligent alarm module 108, the staying time here can be the time range required to evacuate the area after the sound and light prompt information is sent, and the alarm information is generated when the maximum evacuation time is exceeded, including but not limited to the monitoring image and the time of staying in the target area. The alarm information can be connected to the monitoring center in a wired manner, or connected to the monitoring center in a wireless manner through a network protocol converter. The worker sets the menu to select the uplink communication interface through the transmission device.

[0094] If the target person is a child, the alarm staying time should be shorter, and the alarm level should be higher than that of an adult, so that the worker can quickly arrive at the scene to evacuate the child.

[0095] In the embodiment, the intelligent alarm module 108 is added, which is configured to generate an alarm information when the area where the target person is located is the target area and the staying time reaches the set time, so as to send the alarm information to the substation monitoring end and the rescue end. Through the intelligent alarm module, human measures can be taken for the target user who stays for a long time without listening to the prompt, and the safety of the personnel is further improved.
