Background technique

The so-called high-risk operations refer to activities that have relatively high risks to the surrounding environment. According to the provisions of the General Principles of Civil Law, highly dangerous operations include high-altitude, high-pressure, flammable, explosive, highly toxic, radioactive, high-speed transportation vehicles, etc. These operations are highly dangerous to the surrounding environment. With the rapid development of market economy and science and technology, urban infrastructure construction and highway construction also develop rapidly. For highly dangerous operations, some unforeseen safety accidents will inevitably occur. The main cause of these accidents is the intentional or inadvertent illegal operation of the operator, which even seriously affects the life safety of the construction personnel and the quality and progress of the project, causing huge losses. The operator's illegal operation is mainly due to the lack of effective monitoring means or supervision measures for the safe operation of construction machinery. In the above-mentioned construction process, personnel safety has attracted more and more attention from the society. In order to improve the construction progress and efficiency, the construction intensity has been increased, and construction personnel often cause accidents due to negligence or fatigue work, which in turn causes personal injury.

For personnel engaged in high-altitude operations, regular safety publicity and education and safety technology training should be carried out, so that they can understand the rules and hazards of accidents caused by falling from heights, firmly establish safety thinking and have the ability to prevent and control accidents, and strictly implement them. Safety regulations, when you find that you or others have abnormal behaviors that violate the rules, or find that objects and protective measures related to high-altitude operations are in an abnormal state, you must change them in time to meet safety requirements, so as to prevent and control falling from high places. Accidents happen.

However, sometimes the injury to personnel is not serious, and it is often that the injury is aggravated or even life-threatening due to failure to detect and treat it in time. Therefore, it is necessary to carry out remote and effective monitoring and control of the existing high-risk operations, to detect the physical status of high-risk workers and to realize remote control of them, so as to achieve the purpose of strengthening the supervision, management and control of the safety of high-risk workers. Stop under the premise of ensuring safety, prevent and reduce the occurrence of safety accidents, and ensure public safety; at the same time, it is conducive to promoting urban construction and development and reducing unnecessary economic disputes.

The remote computer processing program saves the data received from the monitored person’s behavior status information detector into the designated service database, so that the monitored person can use a computer to access the designated address through the Internet at a remote location, and use an independent login name and password to enter the network service program, check the specific geographical location, current behavior status and abnormal alarm information of the monitored person, and check the previous action route and physical condition of the monitored person through the computer operation interface; People's activity area, activity state, body temperature alarm limit, etc. are set according to requirements.

The system also supports the monitor to send a text message in a specified format to the phone number of the monitored person's behavior status information detector used by the monitored person through the mobile phone. And the specific Chinese location description information is fed back to the monitor. After obtaining the information of the monitored person, the monitor makes a decision to rescue the monitored person who needs rescue, so as to achieve the purpose of protecting the monitored person. the

Description of program detection, judgment and analysis in the monitored person's behavior state information detector: 

The processing program conducts comprehensive analysis, calculation and evaluation on the current position data, speed, body temperature, skin impedance, movement status, falling speed, direction angle and historical data of the monitored person, and confirms the current danger level after evaluation; the monitoring person The evaluation boundary can be re-modified according to the actual state of the monitored person to reduce false positives and missed negatives. the

Sudden fall recognition:

Normal fall: After receiving the data of a sudden fall and the azimuth angle change is greater than 60 degrees, the program judges whether the body temperature and skin impedance of the monitored person have changed and saves it. Within seconds, the angle remains the same and the temperature of the human body does not change much. At the same time, it is judged whether the change of the position data and the movement data before the fall are 0, and if it is, it is recognized as a normal fall. the

Rapid fall: It takes less than 0.3 seconds after the fall is completed and the last change in the falling angle is greater than 120 degrees, but the body temperature does not change much. At the same time, it is judged whether the position data change and the movement data before the fall are 0. If it is, it will be recognized as a rapid fall and be recognized. Monitors may be injured. the

Onset fall: After receiving the fall data, it is detected that the body temperature of the monitored person changes abnormally at the same time. If the difference between the skin impedance and that saved 30 seconds ago is too large, it is considered that the monitored person has a sudden disease fall. By saving body temperature and skin impedance change time, it is also possible to roughly estimate whether the monitored person is in shock or awake. the

Recognition of wrestling in sports:

When the program receives the falling data and the angle change is greater than 60 degrees, if it detects position data change and speed change data at the same time, and the current body temperature and skin impedance of the monitored person are significantly different from the average data saved normally, it can be identified If you fall for sports, you can also confirm the severity of the fall according to the position change, movement speed, body temperature and normal difference. the

Sudden onset recognition:

If the central data processing program recognizes that the body temperature and skin impedance of the monitored person have undergone drastic changes, and the range of activities within 10 minutes is narrow, and the acceleration sensor does not detect the occurrence of fast movement information, it can be judged that the monitored person may have a disease. Timely rescue treatment. the

walking recognition:

The central data processing program can confirm that the monitored person is currently walking according to the change of satellite positioning coordinate data per second and the moving speed is less than 8 kilometers. At the same time, the acceleration sensor has movement and azimuth angle changes. the

Running recognition:

When the program recognizes that the monitored person is moving at a speed of 6 to 20 kilometers, and the body temperature is higher than normal, the skin impedance is low, and the azimuth angle changes greatly, it can confirm that the monitored person is running. If the body temperature and skin impedance are normal, and If the range of activities changes less than 200 meters every 5 minutes, it is confirmed that the monitored person is only doing general exercise. the

Identification by means of transportation:

When the program recognizes that the satellite positioning position data changes greatly per second and the moving speed is greater than 20 kilometers, it is judged that the monitored person is in a vehicle, and the remote computer program can also combine the electronic map and the monitored person's moving route to roughly confirm the ride. The type of vehicle. the

Recognition of leaving the specified scope of activities:

The monitor can set a frequent activity area for the elderly and children who are easy to get lost through the remote operation program interface. When the program recognizes that the current geographic location coordinates of the monitored person leave the set area, the monitor will be notified in time. The activity area can be based on Multiple settings are required. the

Access Restricted Area Identification:

For certain sensitive areas that the monitor does not want the monitored person to enter, such as: Internet cafes, game halls, dangerous road sections, etc., the monitor can set it on the remote operation program interface, so that when the hardware processing program detects that the monitored person enters the restricted area Information will be sent to monitors in time, and multiple restricted areas can also be set as needed. the

Leaving home identification:

The monitoring person can set the place of residence as an out-of-bounds alarm mode, so that when the monitored person leaves the specified area, the central data processing program will also notify the monitored person in time. the

Hazard Identification:

When the monitored person presses the emergency call button on the detector, the central data processing program will confirm that the monitored person is: general call, robbed, sick Call for help and other information, and send it to the telephone and remote service program designated by the supervisor in time. the

Normal state recognition:

When the central data processing program does not detect the above abnormal information, it will automatically query the time according to the interval set by the monitor, and send the current basic information of the monitored person: such as body temperature, location data, moving speed, etc. to the remote computer processing program for storage, so as to provide The supervisor can inquire at any time. the
