Abstract

The invention provides an early warning method and a device. The method comprises the following steps: acquiring a first video shot at an operation site; determining a first geographical range definedby a plurality of target objects based on the first video, wherein the first geographical range is an operation area in the operation site, and the target objects are specific objects used for surrounding the operation site; determining whether a violation behavior exists in the first geographical range or not; if the violation behavior exists in the first geographical range, generating first alarm information according to the violation behavior; and outputting the first alarm information. By means of the method, the violation behavior of the operation site can be intelligently recognized, early warning is conducted in time on the operation site, and the violation behavior recognition efficiency and the violation behavior early warning real-time performance are improved.

Description

technical field

[0001] The present application relates to the technical field of violation identification, and in particular to an early warning method and device. Background technique

[0002] In the manufacturing process of manufacturing enterprises, the unloading operation of tank trucks for the production of fuels or raw materials such as alcohol, hazardous chemicals, and liquid nitrogen is a high-risk operation, which is likely to cause accidents and personal safety.

[0003] In the process of unloading operations, operators are generally required to do personal protection first (such as wearing safety helmets, protective clothing / static clothing, gloves, masks, goggles, etc.), and on-site protection (such as setting isolation belts, feeding tankers Place the vehicle backstop), and arrange supervisors to monitor the entire operation process, and dissuade non-operators from intruding, and operators from making phone calls, smoking and other dangerous behaviors. That is ...

Examples

Embodiment 1

[0080] Please continue to see figure 1 , taking the liquefied gas unloading operation site as an example, the operators set up a binocular camera 101 at the liquefied gas unloading operation site in advance, the first camera of the binocular camera 101 collects the thermal imaging video of the liquefied gas unloading operation site, and the second camera Visible light video of the liquefied gas unloading operation site is collected.

[0081] The binocular camera 101 has an analysis function, that is, the binocular camera 101 can directly analyze the thermal imaging video, and determine whether the thermal imaging video is There are violations such as smoking, fireworks, and making phone calls. When the binocular camera 101 recognizes that the operator has a smoking behavior, the flash module of the binocular camera 101 emits light, the sound module outputs prompts such as "no smoking", and the relevant alarm information is sent to the second server 102 through the first serve...

Embodiment 2

[0085] Please continue to see figure 1 , taking the liquefied gas unloading operation site as an example, the operators set up a binocular camera 101 at the liquefied gas unloading operation site in advance, the first camera of the binocular camera 101 collects the thermal imaging video of the liquefied gas unloading operation site, and the second camera Visible light video of the liquefied gas unloading operation site is collected. After the first camera and the second camera capture the video, they are both uploaded to the first server 102, and the first server 102 identifies violations.

[0086] For the thermal imaging video collected by the first camera, the first server 102 determines whether there are illegal behaviors such as smoking, fireworks, and phone calls in the thermal imaging video according to the temperature corresponding to each object to be detected in the thermal imaging video and the posture of the operator . When the first server 102 recognizes that the...
