The system mainly completes the collection and storage of parameters such as temperature, residual chlorine, alkalinity and acidity in the swimming pool, and has the functions of transmitting data to the monitoring center and executing the instructions of the monitoring center. The system adopts the conventional RS-485 and other wired data communication methods, and is equipped with a dedicated swimming pool water quality monitoring system software, which is convenient for networking, high reliability, low cost, easy to maintain and data storage and analysis for the environment. Under abnormal circumstances, the corresponding personnel can be notified by various forms of alarms, and the records can be monitored in real time 24 hours a day. The system can be widely used in swimming pools and other fields. The swimming pool water is directly in contact with the human body, and various bacteria or viruses such as skin diseases, digestive diseases, excretions and epidemics cause water pollution and become a source of transmission of some diseases. The fact that there are adverse reactions after swimming is endless, so swimming pool water quality management is an important issue related to the health and health of swimmers. Strict disinfection and sterilization of pool water is an important part of preventing the spread of various diseases and ensuring the health of swimmers and the quality of pool water. Especially in the case of people in summer, managers must pay great attention to this. Through on-line real-time monitoring of the main indicators of swimming pool water quality, we ensure that the water, temperature and water quality of the pool are qualified, and the swimmer's health is effectively guaranteed. The system consists of programmable controller (PLC), network temperature and humidity transmitter, sensor, communication conversion module, sound and light alarm, computer and system monitoring software. According to the information collected by the temperature, residual chlorine, alkalinity, acidity and other sensors in the swimming pool, the sensor information is sent to the 485 to 232 converter using the RS485 bus, and is connected to the host computer for display, alarm and inquiry. The monitoring center displays and stores the received sample data in a tabular form, and then compares it with the set alarm value. If the measured value exceeds the set range, an alarm or voice alarm is displayed through the screen, and the record is printed. At the same time, the monitoring center can issue control commands to the field controller. The monitor controls the fans, pumps, and other equipment to cool and dehumidify according to the instructions to ensure the growth environment of the crops in the greenhouse. The monitoring center can also activate the sound and light alarm device on the on-site monitor through the alarm command, and inform the swimming pool management personnel to take corresponding measures to ensure the environment in the swimming pool is normal. The system can monitor and collect more parameters of swimming pool water quality according to customer needs. The monitoring points can also form RS485 network of 100-300 monitoring points according to requirements. The software can set the time interval for collecting data, monitor the temperature and humidity of all monitoring points in real time, and set the upper and lower limits of each temperature and humidity. At the same time, it can be alarmed by sound and light alarm, for the convenience of customers to monitor, browse, Query and save historical data.
