[0021] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0022] like Figure 1 As shown, an embodiment of the present invention discloses an emergency broadcast management system for a chemical park, comprising: An identification allocation module, used to allocate a unique code to the emergency broadcast terminal, and register the identification information of the emergency broadcast terminal into an identification resolution system, wherein the identification resolution system includes a campus node and an enterprise node, and the emergency broadcast terminal is a subordinate node of the campus node; A set determination module, used to collect real-time monitoring data of the chemical park based on a plurality of pre-deployed sensors, and analyze the real-time monitoring data to determine a risk level reference data set; A model training module, used for acquiring historical events of the chemical park, determining a model data set according to the historical events, and training an emergency broadcast risk impact model based on the model data set; A coefficient calculation module, used to output the risk impact factor of each real-time monitoring data in the risk level reference data set based on the emergency broadcast risk impact model, and calculate the emergency broadcast coefficient of the emergency broadcast terminal according to the risk impact factor; The broadcast management module is used to generate an emergency broadcast message based on the emergency broadcast coefficient, and push the emergency broadcast message to the lower-level node according to the identification resolution system.

[0023] In this embodiment, the park identification resolution system provides unified identity identification and resolution services for each element of the park security risk management and control, and is divided into park nodes and enterprise nodes. Enterprise nodes directly provide services to enterprises, and realize the collection of underlying identification data such as products, machines, workshops, and factories within the enterprise; park nodes can connect upstream and downstream enterprises within the park, and use identification resolution to provide data query services on demand, so as to achieve the purpose of data sharing within the park.

[0024] In this embodiment, based on the park's identification resolution system, the safety production related elements in the park are registered in the identification resolution system. Based on the principle of identification code uniqueness, the identification resolution system will assign a unique code to each registered object. When registering the identification, the upper and lower management relationships of all objects in the park can be maintained by filling in the identification of the superior object or the subordinate object to which each object belongs.

[0025] In this embodiment, the main information that needs to be filled in when registering is illustrated by example: Sensor equipment: company to which it belongs, sensor name, monitoring indicators, alarm threshold, gateway identification code, and security officer identification code.

[0026] IoT Gateway: company to which it belongs, gateway name, gateway IP address, TCP / IP protocol port, MQTT protocol port, campus platform identification code, etc.

[0027] Valve: company, valve name, valve IP address, TCP / IP protocol port, MQTT protocol port, and park platform identification code.

[0028] Emergency broadcast: company, installation location, device name, broadcast IP address, TCP / IP protocol port, and MQTT protocol port.

[0029] Security manager: company to which he or she belongs, name, phone number, and park manager identification code.

[0030] Park manager: name, phone number, position.

[0031] Intelligent safety risk management and control platform for chemical parks: platform IP address, HTTP protocol port, emergency information receiving identification code (multiple), and superior platform identification code (i.e., government-side supervision platform).

[0032] In this embodiment, the park platform needs to access the real-time monitoring data and alarm data of the sensors in the key control areas of the enterprise. The general practice is that the park uniformly establishes an Internet of Things gateway to connect the relevant sensor data of all enterprises in the park. Each sensor needs to be connected. The gateway address and port for pushing data are fixed. If a new gateway is built in the park or the gateway address changes due to network adjustment, all connected sensors need to reset the gateway address once. If the gateway information to which the sensor belongs is configured in the identity resolution system, the sensor performs an identity resolution query before reporting the data, and pushes data according to the information such as the gateway address and port to which it belongs. In this way, when the gateway address changes, it is not necessary to reset each sensor, but only to modify the IP and port of the identification object corresponding to the gateway in the identity resolution system. After receiving the data reported by the sensor, the Internet of Things gateway needs to push the data to the park platform, that is, the intelligent control platform for safety risks in the chemical park. The park platform needs to push the relevant data to the government-side supervision platform in accordance with the data exchange specification requirements. Before pushing data, the relevant information of the parent platform can be queried through the identification resolution system and then pushed. If the information of the parent platform changes, the gateway configuration and the campus platform system do not need to be modified. Only the information of the corresponding identification object needs to be updated in the identification resolution system, so as to flexibly realize the update of the parent platform information.

[0033] In this embodiment, the enterprise security manager also needs to keep abreast of the alarm conditions of sensors in key areas of the enterprise. At this time, the relevant security manager can also be registered in the identification resolution system, and the security manager identification of the sensor can be configured in the identification resolution system. The sensor can actively query the identification resolution system to obtain the information of the security manager to which it belongs, and send a text message to the relevant security manager when an alarm occurs. If the security manager changes or his mobile phone number changes, the latest mobile phone number of the security manager can be queried and obtained in time through the identification resolution system, so that the sensor warning information can be sent to the relevant security manager in a timely and flexible manner. The security manager and the park manager can query the information of their superior manager through the park identification resolution terminal and report the warning situation.

[0034] The beneficial effect of the above technical solution is that the present invention can realize efficient and intelligent management of emergency broadcasts, meet the needs of fast and accurate dissemination of emergency broadcast messages, and realize the step-by-step push and flexible expansion of emergency broadcast messages.

[0035] In some embodiments of the present application, it also includes: A code traversal module, used for performing code traversal in the identity resolution system; A first judgment module is used to judge whether the identification resolution system has a code matching the unique code, and if not, register the identification information of the emergency broadcast terminal into the identification resolution system; If yes, extract the corresponding registration identifier, and analyze the registration identifier to determine the corresponding registered emergency broadcast message receiving object; An identification analysis module, used to analyze the identification information of the emergency broadcast terminal to determine the corresponding emergency broadcast message receiving object; A second judgment module is used to judge whether there is an intersection receiving object between the registered emergency broadcast message receiving object and the emergency broadcast message receiving object, and if not, register the identification information of the emergency broadcast terminal into the identification resolution system; If so, the intersection receiving object is updated to the registration identifier.

[0036] In this embodiment, a unique code is assigned to the emergency broadcast, but when a new emergency broadcast message receiving object is added, the emergency broadcast message needs to be updated to the identification resolution system. Therefore, the newly added emergency broadcast is also assigned a corresponding unique code, so it can be matched in the identification resolution system.

[0037] The beneficial effect of the above technical solution is: after the emergency broadcast type of emergency broadcast message receiving object is added, the present invention only needs to update the emergency broadcast to the identification resolution system, and configure the emergency broadcast identification object as a subordinate node of the park identification object. The park platform queries the identification resolution system to obtain the subordinate identification object that receives the emergency response information, and pushes the emergency broadcast message to the relevant subordinate nodes, which can flexibly expand the emergency response information sending method.

[0039] In this embodiment, the real-time characteristic data includes inorganic irritating gases, toxic and harmful volatile organic compounds, malodorous gases, etc. Specifically, these harmful gases include but are not limited to SO2, H2S, NH3, NO2 / NO / NOX, vinyl chloride, benzene, toluene, methyl mercaptan, carbon disulfide, etc. Each harmful gas has a corresponding alarm value, that is, a standard monitoring data value.

[0040] In this embodiment, the emergency broadcast factor is the characteristic data that causes the emergency broadcast, such as SO2, H2S, NH3, NO2 / NO / NOX, etc.

[0041] In this embodiment, the emergency broadcast factors and standard monitoring data values ​​are compared in numerical value to determine the left boundary data value and the right boundary data value, thereby further realizing the accuracy of the emergency broadcast. In actual situations, in order to ensure safety and health, the alarm value is lowered. Therefore, the numerical value corresponding to the emergency broadcast factor is lower than the standard monitoring value.

[0042] In this embodiment, the first calculated value is an average value, and the second calculated value is a standard deviation.

[0043] The beneficial effect of the above technical solution is that the present invention can lay a foundation for the accurate push of emergency broadcast messages and provide a reliable basis for judgment by determining a risk level reference data set.

[0045] In this embodiment, historical event data of the chemical park are first collected, including emergency broadcast records, expert evaluation reports and historical monitoring data, which provide a basis for learning and prediction of the model.

[0046] In this embodiment, the preprocessing step includes removing outliers (i.e., data points that do not conform to the normal pattern) and processing missing data (filling or deleting missing data points), thereby ensuring data quality and model performance.

[0047] In this embodiment, based on risk theory and domain knowledge, the model training module extracts features related to risk impact from pre-processed historical events. These features include impact range (geographical or population range affected by the event), recovery time (time required to return to normal), economic loss measure (economic cost caused by the event), and social impact index (the degree of impact of the event on society).

[0048] In this embodiment, the model training module selects a pre-set neural network model and iteratively trains the model using the training subset. This process involves running the training algorithm multiple times and adjusting the model parameters until the model reaches a satisfactory performance level.

[0049] The beneficial effect of the above technical solution is that the present invention can train a model that can evaluate and predict the risk impact of emergency events in chemical parks, and accurately output the risk impact factor of each real-time monitoring data.
