0.Introduction. Different from other building facilities, hospital buildings require huge electrical energy consumption after they are put into use, because hospitals are indispensable public facilities in our daily life, and play an important role in maintaining people's health and safety. This also requires the relevant regulatory departments to clarify the particularity of hospital buildings and do a good job in the comprehensive monitoring and management of the hospital building electrical industry.
1.Characteristics and requirements of the hospital construction industry.
Hospital building is a common public facility in our daily life, this public facility has an important role in ensuring the safety of people's lives, because the hospital needs some serious patients, therefore, the hospital building usually has to maintain 24 hours a day to prevent important patients from appearing in a certain period of time. In order to better meet the needs of the society, the hospital building electrical industry needs to supply power all day long when supplying power to the hospital, unlike other buildings, if the electrical industry does not meet the power requirements of the hospital building, then it will threaten the safety of people's lives to a certain extent, and even cause more serious consequences. Moreover, the hospital building electrical industry should take into account the particularity and complexity of the hospital building work as a whole in the process of electric power, because there is an obvious division of labor in the hospital building, for example, the operating room is different from the ordinary diagnosis room, the power of the operating room must be well guaranteed, only sufficient power and equipment guarantee can help medical personnel complete the patient's surgical work more effectively, in order to better ensure the orderly work of the operating room, The hospital building electrical industry even needs to provide backup power for important departments such as operating rooms to prevent the power system from having problems and affecting the normal work of the hospital. At the same time, there are a lot of equipment with great power demand in hospital buildings, which play a very important role in diagnosing patients and patients, therefore, the hospital building electrical industry should monitor and manage the various medical devices in the hospital building to ensure that the electrical equipment can effectively provide good power energy for these equipment and make these equipment operate normally. In order to better monitor the electrical situation in the hospital building, the electrical industry needs to monitor and manage the electrical situation in the hospital building through Internet information technology, because the intelligent electrical monitoring system can better help the electrical industry to supervise and manage the electrical situation in the hospital building, and the intelligent electrical means are not limited by space and time, which can effectively improve the power efficiency of the hospital building and effectively guarantee the power of the hospital building. Keep hospital buildings up and running.
In addition, the hospital building electrical industry in the guarantee of sufficient power at the same time, but also to ensure the quality of hospital building power, because the hospital building in the daily work and operation process, need to use a lot of high-precision, high-tech and high power demand equipment, the electrical industry in the process of hospital power, to monitor the power use of these equipment through intelligent power equipment, to provide these high-precision medical equipment with higher quality power support, In this way, these medical devices can operate and work better and serve the people better. Moreover, in addition to setting up backup power supply for some important departments, the electrical industry should also use intelligent power equipment to monitor the power usage of hospital buildings in real time.
2.Analysis of comprehensive monitoring and management strategies in the hospital building electrical industry.
2.1. Strengthen the management of electrified fire monitoring equipment.
Because hospital buildings need a lot of electricity, some hospital buildings are likely to induce circuit failures after excessive use of electricity, which will lead to fires, which occurs from time to time in China, including the aging of internal circuits in hospital buildings, the wrong operation of the electrical industry and the excessive use of electricity in hospital buildings. This electrified fire phenomenon in hospitals will not only threaten the overall work efficiency of the hospital, but also may threaten people's lives to a certain extent. In order to better monitor the power of hospital buildings and prevent electrical fires, the electrical industry should set up safety management devices and alarm systems in hospital buildings, and link this alarm system with the monitoring equipment of the electrical industry. If the alarm system within the hospital sends an alarm signal, the staff of the hospital should do a good job of prevention and control and deal with the circuit problem in a timely manner. At the same time, the electrical industry should also timely supervise and control the occurrence of related problems, once this phenomenon occurs, the electrical industry should promptly dispatch maintenance personnel to repair and deal with the power problems in the hospital, prevent the problem from expanding, and control the problem in a small range. In addition, the electrical industry should also guide hospitals to do a good job in electrical fire prevention, so that hospitals can respond to electrical fires more calmly. In addition, the electrical industry should also monitor the use of hospital electricity in real time, if the hospital power system fails, the electrical industry needs to adjust the power system in time to prevent the spread of electrical fires, which requires the electrical industry to constantly update its own data equipment, and statistics and analysis of the power data inside the hospital building.
2.2. Improve the management of fire-fighting electrical equipment.
In order to better prevent and control the spread of electrical fires inside hospital buildings, the hospital building electrical industry should install fire-fighting electrical equipment inside the hospital building, because in the process of electrical fire diffusion, fire rescue personnel and power maintenance personnel may not arrive at the scene in time to deal with it, so the electrical industry must install fire-fighting equipment in the corresponding position. In order to ensure that the fire-fighting equipment inside the hospital building can be used correctly and effectively, the electrical industry should provide a special power supply system for the fire-fighting equipment to ensure that the fire-fighting equipment can be effectively used in special situations to better help medical staff control the spread of the problem. In the process of daily operation, the electrical industry should monitor and manage the power supply data of the fire equipment inside the hospital building to ensure that the fire equipment can operate normally, if there is a certain problem with the fire fighting equipment, the electrical industry should replace and repair it in a timely manner to ensure that the fire equipment can be put into use normally, at the same time, the electrical industry should also advocate that the hospital internal personnel should be proficient in the use of fire fighting equipment, and let the medical staff clarify the working principle of the fire protection equipment and the power supply system. Let medical staff pay attention to the operation of fire-fighting equipment to prevent problems.
2.3. Strengthen the supervision of the use of electricity in hospitals.
In order to better ensure the efficiency of the hospital's electrical equipment, the electrical industry should strictly supervise and control the power consumption inside the hospital building, and the electrical industry should use information technology to establish a platform for supervising the internal power use of the hospital building, collect and analyze the power data inside the hospital, and ensure that the power system inside the hospital building has a certain safety and stability. At the same time, the electrical industry should set up a power failure alarm system in the hospital to observe the power usage of the hospital in real time to prevent potential failures. In order to ensure the stability of the internal power supply of the hospital at the same time, the electrical industry should also do a good job in the prevention of power failures inside the hospital building, real-time detection of power grid load problems, once there is a power failure, the electrical industry should timely shut down the local power system, or let the hospital internal personnel turn off the corresponding power supply device, and then send maintenance personnel to deal with and repair the corresponding problems, to ensure that the power has safety and reliability, to provide good power energy for the hospital building, so that the hospital facilities can run better.
