Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of safety alarms, and in particular to an indoor gas leakage processing system and a processing method. Background Art
[0002] As one of the important energy sources in daily life, gas is widely used in households, commerce, industry and other fields. However, gas itself is flammable and explosive. Once it leaks and accumulates to a certain concentration, it is very easy to cause fire or even explosion when encountering excitation sources such as open flames or electric sparks, seriously threatening people’s lives and property safety. In the early gas use environment, gas leaks were mainly monitored through manual inspections and handheld detection instruments. With the improvement of people’s living standards and the enhancement of safety awareness, more and more users have begun to pay attention to the safety of gas use.
[0003] For example, Chinese patent publication number: CN110930628A discloses an indoor gas remote alarm system and an indoor gas remote alarm method, which include a PLC, the PLC is connected to a plurality of carbon monoxide sensors, an audible and visual alarm and a circuit breaker, the circuit breaker is connected to the indoor main power supply, the PLC is connected to a GPRS communication module, and the GPRS communication module is connected to two or more mobile terminals.
[0004] In the prior art, the system relies on mobile terminal users to respond to alarms and take actions in a timely manner. If the user fails to see the alarm in time or cannot respond immediately, the processing may be delayed, resulting in gas leakage. Although automatic power cut-off can prevent fire, it may also cause indoor ventilation and emergency lighting equipment to stop working, limiting the ability to respond to gas leaks in all aspects. Therefore, how to deal with indoor gas leaks in a timely manner and ensure the linkage application between various safety systems is a problem we need to solve. To this end, an indoor gas leakage processing system and processing method are proposed. Summary of the invention

[0024] The risks in multiple detection cycles are integrated and accumulated, and the maximum safety duration threshold is preset according to the concentration peak and change rate trend of the detection cycle. The abnormal gas assessment index is analyzed to evaluate the severity and potential risks of the current abnormality;
[0025] Based on the abnormal gas assessment index and safety range data, the abnormal alarm levels are preset, namely, slight abnormal alarm level, medium abnormal alarm level and high abnormal alarm level, and the corresponding abnormal alarm threshold is set for each abnormal alarm level. According to the set abnormal alarm level, the corresponding abnormal management measures are matched. The abnormal management measures include ventilation enhancement, valve closing, emergency notification and linkage control. Ventilation enhancement: automatically start or enhance the ventilation system to reduce the concentration of harmful gases. Valve closing: automatically close the gas or fuel gas valve to prevent further gas leakage. Emergency notification: send emergency notifications to relevant personnel through sound and light alarm systems or mobile devices.

According to the layout of the indoor structure and potential gas leaks (such as gas pipelines, stoves, etc.), various sensors are deployed to ensure coverage of the entire indoor space, especially the potential danger areas.

It is used to monitor indoor temperature. Abnormal temperature may indicate fire or other dangers. Humidity sensors are used to monitor indoor humidity. High humidity can easily affect the performance of other sensors, thereby increasing the risk of electrical fires. Sensors continuously monitor the parameters they are responsible for, capture changes in the environment in real time, collect indoor gas concentration data, convert the monitored data into electrical signals, and transmit the converted electrical signals to the early warning alarm center through the communication interface to form comprehensive environmental data. Sensor data is pre-processed, including noise filtering and data calibration. Sensor data is filtered to remove noise and interference signals to ensure data accuracy. Sensor measurement data is corrected to ensure the accuracy and consistency of the sensor. Calibration is performed regularly to cope with sensor aging and drift;
[0072] The abnormal characteristic analysis module is used to analyze the indoor gas concentration data collected by the sensor module, classify the abnormal gas types, retrieve the associated data of the abnormal gas safety range, extract the abnormal gas characteristics, obtain the abnormal characteristic data table, extract the pre-processed indoor gas concentration data from the early warning alarm center, including the measurement values of carbon monoxide, combustible gas, smoke, temperature and humidity parameters, and standardize the indoor gas concentration data to unify the dimensions and ranges of different types of data for easy comparison and analysis.

Linkage control: start the linkage mechanism with other emergency services such as fire protection and medical care.
[0074] Furthermore, the expression of the abnormal gas evaluation index is:
[0075]
[0076] Among them, RAI is the abnormal gas assessment index, Cp i is the peak concentration of the i-th detection cycle, Rt i is the rate of change of the ith detection cycle, B is the reference value, which represents the expected peak concentration under normal operating conditions, Dt is the duration of the abnormality, that is, the time from the beginning of the abnormality to the detection, T max is the preset maximum safety duration threshold. Exceeding this time may indicate a serious situation. n is the number of detection cycles. When Cp i When Dt is close to or equal to B, RAI is small, indicating low risk. max When the index part will decrease significantly, resulting in a decrease in the overall RAI value, indicating an increase in risk. i When it is very high, the denominator increases and the overall RAI value decreases, indicating an increase in risk. Normalizing the difference between the peak concentration and the baseline value by the rate of change in the form of It indicates the impact of abnormal duration on risk. As time increases, the risk index decreases, emphasizing the importance of rapid response. max A time threshold is set, beyond which the risk increases dramatically;
[0077] A plurality of abnormal alarm levels correspond to a plurality of abnormal alarm thresholds;
[0078] The multiple abnormal alarm levels and the multiple abnormal alarm thresholds satisfy the following relationship:

Used to adjust the deviation between RAI and the reference value. The larger the deviation, the greater the safety warning factor. When Dt approaches or exceeds T max When the index part will be significantly reduced, resulting in an increase in the SAC value, indicating an increase in risk. When the value is large, it means that the concentration changes rapidly and the SAC value will also increase, indicating a higher risk. base When , the SAC value will also increase, indicating that the current risk status is significantly different from the normal status;
