The analysis result is then transmitted back to the secure mobile terminal. (secure just without returning, reduce data volume)
8. Security policy and rule management module H: the remote safety analysis platform belongs to a remote safety analysis platform, and places general construction site safety strategies and rules and construction site specific safety strategies and rules. The specific definition of security policies and rules is described in another patent family, which is only necessary to construct a complete system. (for example, a person can be defined to have a safety helmet and no person can stand under the suspension arm and outside the lifting hook)
9. Building site safety identification engine I: belongs to a remote safety analysis platform and is called by a comprehensive safety analysis module to identify the position of the current safety analysis platform and the specific construction (what building or construction equipment or what composition) displayed in the video
10. A data transmission module J: the system belongs to a remote security analysis platform and is used for receiving video data transmitted by a security mobile terminal and data acquired by other auxiliary sensor equipment. And returning the analysis result of the platform to the safe mobile terminal.
The invention is characterized in that the mobile safety mobile terminal dynamically analyzes the safety condition of a construction site in real time by collecting panoramic video and voice and matching with auxiliary sensor equipment data. For simple analyses, the analysis is done on a cartridge, and for complex analyses, on a remote integrated analysis platform. And submitting suspected safety problems or safety problems which cannot be judged to a remote security officer for analysis and judgment. Meanwhile, a security officer can check each mobile video monitoring condition at a far end in real time and perform safety judgment regularly and manually.
The security judgment of the patent is not limited to the judgment of a single secure mobile terminal. But also comprehensive judgment of a plurality of secure mobile terminals. Because a plurality of field personnel can be contained in one construction scene, the video angle and the sensor information transmitted by each person are different, and the people can see no what safety problem singly, but the people can analyze potential safety hazards when seeing the video angle and the sensor information together. However, how to determine how to link multiple secure mobile terminals will be described in another patent family.
Examples
a) And the remote security analysis platform is used for configuring security policies and rules. For example, if a person is detected, a safety helmet is always worn on the head; such as detecting a crane, the front of the crane is not capable of standing; for example, the construction site wall is higher than 2.5 m; for example, fire extinguishing equipment is needed in a construction site; such as mechanical earthmoving, the position of the excavator needs to be fixed firmly, etc. And converting the related security policy into data and a mode which can be identified by the video.
b) The site safety identification engine imports general site buildings and construction equipment and mechanical tools. Video models such as excavators, cranes, and the like; building video model; a human; and identifying the video model by a construction signboard and the like. Prior to importing these data, worksite security recognition has led to the ability to learn and master these models, in a self-learning manner such as machine learning, with what constructs can be presented by seeing the video. This belongs to the video machine learning general knowledge domain content. How to learn is beyond the scope of this patent, but the existence of this engine module is still significant to the patent's overall system.
c) The security policies and rules are classified by the platform, and the platform considers that the security mobile terminal can process and issues the rules to the security mobile terminal. If the platform processes itself due to the rules that require significant processing power.
d) The safety mobile terminal is fixed in a safety helmet or on two sides (if the safety helmet is in the safety helmet, a hole needs to be dug, and a camera can be seen). And starting the secure mobile terminal.
e) As people entering the construction site wear the safety helmet, videos of places where people pass are collected in real time. And is analyzed in real time by the local safety analysis module and the remote comprehensive safety analysis module.
f) As the helmet moves, a person appears in the video, and since the rule of human body recognition has been defined as local edge calculation of the safety box before, the edge safety analysis module D performs analysis to detect whether the person carries the helmet or not (video detection of whether the helmet is carried or not belongs to the identification technology), and if the person does not carry the helmet, the person immediately informs the alarm indicator C to send out a voice prompt (the person takes no attention to the helmet, which is specifically configurable).
g) As the helmet is moved, a crane appears within the video, and the object, which is not configured to be identifiable locally in the security box, is transmitted to the remote security platform via the data transmission module E. The comprehensive safety analysis module G firstly calls a construction site safety identification engine I, and the crane is judged to be a crane through the engine I, so that the safety analysis module G can search the safety rules of the crane in the safety strategy management module H. The safety rule is found to be that the front of the crane cannot stand a person, and further the engine I is called to judge whether a person is present at a position in front of the crane inside the video.
h) Once a person is found in the front position of the crane, the comprehensive safety analysis module generates an alarm record (including an alarm level), and on the one hand, the alarm record is stored in the safety platform and is transmitted to the safety display and alarm module F to be seen by a safety officer; on the other hand, the alarm is transmitted to the secure mobile terminal through the data transmission module J.
i) And after receiving the alarm, the safety mobile terminal starts an alarm indicator C to alarm according to the alarm level. The alarm indicator gives an alarm to other objects according to the alarm category, so that the sound and the light flash.
j) As the helmet moves, when the helmet detects a high front temperature (exceeding the construction site specified problem, such as 40 degrees), the edge safety analysis module D also responds to inform the warning indicator of vibration and inform the person to stop advancing.
k) The workman has taken off the safety helmet suddenly this time, and GPS or big dipper show now still in the building site, but pressure sensor has detected the safety helmet and has not taken overhead, and edge safety analysis module D also can analyze out this kind of condition this time to produce the warning. (this is a special case, of course, if the cartridge is not built into the helmet without this strip)
Certainly, the safe mobile terminal of this patent still has some other uses of non-safety analysis, for example as long as enter the building site gate every day, the video just can detect, just can count an attendance record, also can count an attendance record when going out of the place gate. This patent is given above as an example, but not limited to this example.
