1. Development background
At the beginning of the 20th century, German doctor Ferris and Austrian psychologist Swartbo discovered a strange phenomenon at the same time: some patients suffered from headaches, mental illness, etc. Fatigue and other reasons require treatment every 23 or 28 days. So they called 23 days the "Law of Physical Strength" and 28 days the "Law of Emotions." Twenty years later, Trisher discovered that students' intelligence changed in a 33-day cycle, so he called it the "Law of Intelligence." Later, people collectively referred to the "law of physical strength", "law of intelligence" and "law of emotion" as the three biological rhythms. In 1937. The first international conference on biological rhythms was held. By 1960, an international conference dedicated to discussing biological rhythms was held in the United States, and biological rhythms was officially born as a new subject. In 1981, "Science Illustrated" magazine published an article "Uncovering the Secret of Biological Rhythms" (February 1981 issue), introducing the wonderful biological rhythms to domestic readers, arousing great interest. Since then, many localities and departments in my country have also carried out research on the application of biological rhythms. Relevant national departments have issued documents affirming the role of biological rhythms in promoting safe production.
Three biological rhythms generally do not change throughout a person's life and are not affected by any acquired influences. Each of the three rhythms has its own highs, lows, and critical days. The periodic changes in human physical strength, emotion and intelligence can all be represented by curves. These three curves are calculated from the date of birth, starting from the midline, first entering the high tide period, then experiencing the critical period, and then turning to the low tide period, and so on. The days when the curve is above the midline are high tides. On the contrary, the days below the midline are low tides (the number of high tide and low tide days is equal), and the day when it intersects the midline (strictly speaking, including 1 day before and after) is critical period. During the period of physical upsurge, people are energetic and full of physical strength, while during the down period, they are tired and listless; during the period of emotional climax, people feel comfortable and high-spirited, and all activities are enveloped in a pleasant state of mind. In the low period, people are irritable, depressed and slow to react, and all activities are shrouded in a depressed mood; in the intellectual high period, people have a sharp mind and strong memory, while in the low period, they are slow, forgetful, and have poor understanding. . During the critical period of biorhythms, the body is in an unstable transitional state, feeling particularly bad about oneself, declining in health, irritable, and prone to getting angry for no apparent reason. At this time, people's relevant abilities and body coordination are poor, and they are prone to making mistakes. , the body is prone to illness and accidents are prone to occur during activities. The three rhythmic cycles are different, but sometimes they overlap on one day, that is, a double critical day or a triple critical day. The overlap of critical days increases the possibility of accidents. Therefore, internationally, double critical days and triple critical days are called a person's "danger days". The curve is as shown in the figure:
According to the statistical analysis of 1,000 car accidents by Swedish scholar Schweien, the number of accidents occurring in the critical period of the perpetrator's biological rhythm is 11 times higher than that in the non-critical period. A statistical analysis of 497 accidents by the former Federal Ministry of Agricultural Machinery in Germany found that 97.8% of the accidents occurred during the critical period of the perpetrator's biological rhythm. my country's Handan Iron and Steel Plant analyzed and counted 174 accidents that occurred in the 13 years from 1973 to 1986. The results showed that 66 occurred during the critical period of the biological rhythm of the parties concerned. The safety technology department of Shanghai Ferroalloy Plant analyzed and analyzed 105 work-related injury accidents and found that 63.8% of the accident victims were in the critical and low ebb periods of their biological rhythms.
As we all know, people are the most active factor in productivity. To achieve safe production, we cannot only focus on equipment and not on people, nor should we only emphasize improving the political quality and professional quality of workers while ignoring the physical health of workers. state and mental state. Safety production must be scientific. The understanding of science is not limited to scientific rules and regulations and scientific management methods, but also includes the scientific understanding of workers and the scientific arrangement of work tasks and working hours. If every worker knows his or her own three biological rhythms and scientifically arranges production, the total number of accidents can be reduced to a minimum.
Safety is an eternal theme in coal mine production.
Although various coal mines take many measures to take strict precautions, accidents may occur at any time. Statistics found that ignoring the three biological rhythms is an important reason for the high number of coal mine accidents. Therefore, in order to promote the sustainable, stable and healthy development of safety work in the coal mine system, strengthen the management and behavioral control of people in the safety production process, consolidate the foundation of safety management, achieve scientific management, innovative means, and proactive prevention, the human biorhythm fingerprint recognition safety management It is of great significance to apply the system to coal mine safety production.
II. System Introduction
Jinan Zhengping Automatic Equipment Co., Ltd. organically combines human fingerprint recognition, human biorhythm and safety management to develop a human biorhythm fingerprint recognition safety management system. The safety management system is mainly composed of computers in the main safety supervision office and other agencies and offices and district teams, wellhead inquiry machines and printers. Its operating network is shown in the figure below.
The human biorhythm fingerprint identification safety management system conducts a comprehensive analysis based on the employee’s date of birth and fingerprint identification, and obtains the results of changes in three aspects of physical strength, intelligence, and emotion of the person in different periods, and analyzes these effects It is a safety and security management method to formulate and implement preventive measures based on the factors of safe production.
Human body biorhythm criticality and safety measures
A. Physical criticality: When a person reaches a critical period of physical strength, the body is in a slightly weaker period than usual, that is, a period of relative fatigue. Take timely adjustments to rest.
B. Critical intelligence: When there is a period of critical intelligence, the intelligence is slower than usual. You must always pay attention to the precautions in the production process to prevent accidents.
C. Emotional criticality: When an emotional criticality occurs, emotions are more volatile than usual. At this time, emotions and thoughts should be adjusted in a timely manner to prevent emotions and thoughts from causing bad behaviors that affect production safety.
D. Double criticality of physical strength and intelligence: When double criticality of physical strength and intelligence occurs, physical weakness and slow intellectual response will occur. Rest should be adjusted in time and work should be arranged appropriately.
E. Double criticality of physical strength and emotion: When double criticality of physical strength and emotion occurs, physical weakness and emotional abnormalities are likely to occur. Pay attention to rest and control emotions, arrange off-duty work, and do a good job of providing assistance and education.
F. Double criticality of emotion and intelligence: When there is double criticality of emotion and intelligence, it is easy to have mood swings and slow intellectual response. You should adjust your emotions and mentality, do a good job of helping and promoting, and do not go down the well.
G. Three thresholds of physical strength, intelligence, and emotion: When there are three thresholds of physical strength, intelligence, and emotion, physical discomfort, slow intellectual response, and abnormal and irritable mood swings are likely to occur. Promote education and focus on management. No one is allowed to go down the well, and the district team should adjust off-duty work.
Practice has proven that the implementation of human biological rhythm control can effectively control people's unsafe behaviors in advance and avoid some adverse consequences. In the process of applying the human biorhythm fingerprint recognition safety management system, we must pay attention to comprehensive analysis, timely reminders, eliminate paralysis and indifference, and persist in it. It can become a good auxiliary means in coal mine safety production management and produce a certain positive effect. , thereby adding an additional barrier to safety production management.
