The temperature in the autumn is variable, and there is a large temperature difference between day and night. Children are prone to having a cold due to temperature changes. Pneumococcal diseases usually manifest as respiratory infections at the initial stage, such as fever, vomiting, earache, and cough. These symptoms are similar to those of the common cold. Parents can easily treat them as ordinary colds. This often delays treatment. The timing. Especially infants between the first and the second year are particularly vulnerable to pneumococcal infection due to low immunity. In addition, frequent colds in autumn and winter can easily cause coughing and sneezing, thus increasing the possibility of pneumococcal transmission. Therefore, the baby's autumn "cold" must not be taken lightly, once the child has fever, cough and other symptoms, it should quickly go to the hospital. The difference between cold and pneumonia In the case of a cold, the lungs are not affected and therefore the breathing is normal. When the lungs are infected, the lungs are ventilated and ventilated due to inflammation and the children's breathing is accelerated and rapidly. If your child has a fever, cough, and shortness of breath, it is not a simple cold but may be pneumonia. He should bring the child to the hospital in time for treatment. From the point of view of symptoms, pneumonia is difficult to distinguish from the common cold or bronchitis. However, in general, the symptoms of pneumonia are severe. The baby often has a listlessness, loss of appetite, irritability, rapid breathing, or superficial performance. Severe children with pneumonia may also have symptoms such as difficulty breathing, alar fan, three concave signs, lips and fingernails. If you find that the baby has the above symptoms, you must bring the baby to the hospital in time. The main symptoms of infant pneumonia The main symptoms of pneumonia in infants and young children are fever, cough, and wheezing. The level of fever varies, and some children do not have fever. The first cough is a dry cough, 2 to 3 days after the cough, there are sputum, infants and young children will not spitting can hear the throat cry, and then began to wheezing. Light and shortness of breath, crying and irritable uneasiness, severe cases can be seen with alar flap, mouth purple, lips purpura, head nod with respiratory respiring breathing, lung auscultation can have large and medium blisters and licking pronunciation, X-ray visible lung The door shadow blur increases. Untreated or undiscovered at this time, it will spread forward, mainly the heart. Children can suddenly irritable and uneasy, breathing difficulties are more serious, dark complexion, lips more cyanosis, cold extremities, weak pulse and other heart failure, blood circulation disorder like. In addition to heart failure, bronchial pneumonia can also cause empyema, lung abscess, subcutaneous and mediastinal emphysema, myocarditis and complications of toxic encephalopathy. Adults must not wait to see it, they should go to hospital for treatment. There is no difference between the two or three days of pneumonia and the common cold. The child can have a fever, a runny nose, sneezing, and a cough. Nearly a week or so later, the disease entered the extreme period, and the body temperature increased further. The cough was not obvious, but began to show wheezing. Severe bruising may occur, and there is a clear hypoxia. After treatment, the second week usually goes into recovery, and the body temperature gradually decreases, and wheezing decreases. At this time, more cough, poor appetite, and weaker spirit. The entire course of pneumonia in children may be long or short, but the general pattern is one to two weeks or so. The child had pneumonia, and he was asked to keep quiet as much as possible. This reduced hypoxia and increased asthma due to irritability. However, children should not be allowed to lie there all day long. They should change their positions frequently, turn over their bodies or hold a hug. Especially during the recovery period, the children cough and squat, and they can pick up the children gently in order to help them. Pat back. In this way, the lungs can be prevented from congestion and promote the absorption of inflammation. How is pneumonia treated and its prognosis? 1, the pneumonia in children's room to ventilate to keep the air fresh, indoor temperature is maintained at 18 ~ 20 °C, the relative humidity of the air is maintained at 60%, in order to facilitate the moisturizing sputum. To turn over regularly, pat the back from the bottom up and encourage the child to cough so that the secretions cough up. 2. Give easily digestible and nutritious foods. When a baby is breastfeeding, it cannot be full, and it is advocated a small number of times. Because of shortness of breath, difficulty in sucking milk, and milking the baby easily during feeding, don't be too quick to feed. After feeding, avoid squeezing the stomach and pat back properly to speed up emptying of the stomach to prevent reflux of the gastroesophageal tract. 3, airway humidification is very important, nebulization can help dilute the phlegm, reduce mucosal edema. 4, should pay attention to ensure that the amount of sufficient liquid, generally children can maintain oral intake of liquid, for children with difficulty eating, you can intravenous fluids. Antimicrobial drugs must be used under the guidance of a doctor. For young children and severe children, hospitalization is recommended. Oxygen should be provided in a timely manner to ensure that the tissue has sufficient oxygen supply to maintain vital organ function throughout the body. The principle of oxygen therapy is to reduce the oxygen concentration as low as possible to increase the blood oxygen partial pressure to a safe level without causing toxic side effects. For those who have complications to be dealt with promptly The therapeutic effect of pneumonia is generally better, but there is currently a prominent problem that is the problem of antibiotic resistance during the course of treatment of bacterial pneumonia. Antibiotic resistance is associated with irrational use of antibiotics, such as the use of antibiotics in the absence of bacterial pneumonia but viral flu. The increase in bacterial resistance makes fewer and less effective antibiotics available, increasing the risk of treatment and mortality in children with pneumonia. How to prevent pneumonia? Prevention of childhood pneumonia is a key component of the strategy to reduce child mortality. Immunization against Streptococcus pneumoniae, Haemophilus influenzae type b, measles and whooping cough is the most effective way to prevent pneumonia. Adequate nutrition is the key to improving children's natural defense function. First of all, it is necessary to fully breastfeed in the first 6 months after birth, which is effective in preventing pneumonia and shortening the period of illness. Handle environmental factors, for example, by providing affordable clean indoor stoves, ventilation through windows to keep air circulation, parents quitting smoking and other measures to reduce indoor air pollution; encouraging good hygiene in crowded homes, paying attention to parents and children Hand hygiene can also reduce the number of children with pneumonia. Vaccines are the most effective means of preventing pneumonia. Children's bacterial pneumonia is mainly caused by SP and Hib. Inoculation of SP and Hib vaccine can avoid 70% of pneumonia deaths, and complications such as sepsis and meningitis are also significantly reduced. At present, these two vaccines have been successfully developed in foreign countries and belong to the second-class vaccine in China. Given the heavy burden of pneumococcal infection in infant pneumonia and the safety and effectiveness of pneumococcal conjugate vaccines, WHO believes that the pneumococcal conjugate vaccine should be given priority in the national immunization programme. In the United States, 3 years after the introduction of pneumococcal conjugate vaccine into the national plan immunization, the incidence of pneumococcal disease in children <2 years of age was significantly reduced, and the incidence of pneumococcal disease was also decreased in people over 5 years of age who were not vaccinated. This may be due to a decrease in bacterial transmission from infants under 5 years of age who have been vaccinated. Immunization is one of the most successful and effective health interventions. It protects children's health globally in a safe and effective manner.

What problems should we pay attention to when using solar energy for power supply?
1. The whole day sunshine time of monitoring points along the expressway shall be considered first. As the main energy of the power supply system comes from sunlight, the sunshine exposure time must be considered, which is particularly prominent in mountainous areas where there is little sunshine, but not in plain areas.
2. Working power, working voltage and current of monitoring facilities along the expressway. After considering the power of the whole load, we can choose the solar panel that is more suitable for the long-term operation of the equipment.
3. If the battery discharge cannot make the monitoring equipment work for a long time, the monitoring system will be paralyzed in the rainy season, but the expressway is prone to accidents in the rainy season.
4. The conversion rate of solar cells is low. At present, the conversion rate of solar cell power supply is only about 20%, that is to say, if the silicon solar cell is spread over a square meter, 100~200W of power can be obtained, which is obviously not enough to meet the long-term operation of the monitoring equipment. Of course, with the development of technology and the improvement of the quality of crystalline silicon cells, we can obtain more power resources in a smaller area in the near future.
