动火离人报警装置监控状态分析数据

通过整合动火离人报警装置的上报时间、离人灶台预警油温、离人灶台报警油温、动火离人预警延时、动火离人报警延时、离人灶台油温预报警延时、动火传感器状态、动火离人探头状态、动火离人时间点、温度探头状态、实时油温等数据，得出动火离人报警装置监控状态分析数据；可以用于实现对厨房动火状态的实时监控，检测到离人过久或油温异常，系统会发出预警与报警，提醒人员返回厨房，并通过物联网技术将报警信息传输至管理人员或控制中心，预防因离人导致的火灾隐患。1.数据采集：通过对动火离人报警装置的上报时间、离人灶台预警油温、离人灶台报警油温、动火离人预警延时、动火离人报警延时、离人灶台油温预报警延时、动火传感器状态、动火离人探头状态、动火离人时间点、温度探头状态、实时油温，进行采集整理汇总。
2.数据计算与预警判断：动火离人时间点为动火离人探头状态从有人切换为无人的最新时间；已离人时间=当前上报时间-动火离人时间点；动火离人预警（动火离人报警）的状态在当动火传感器状态为动火，并且动火离人探头状态为无人，已离人时间>设定的动火离人预警延时（动火离人报警延时）时，动火离人预警（动火离人报警）的状态改变为启动预警（报警）；离人灶台油温预警（离人灶台油温报警）的状态在当动火传感器状态为动火，并且动火离人探头状态为无人，实时油温>设定的离人灶台预警油温（离人灶台报警油温），并且已离人时间>离人灶台油温预报警延时，离人灶台油温预警（离人灶台油温报警）的状态改变为启动预警（报警）。
3.数据应用：用于实现对厨房动火状态的实时监控，检测到离人过久或油温异常，系统会发出预警与报警，提醒人员返回厨房，预防因离人导致的火灾隐患。

By integrating data including the reporting time of the unattended cooking fire alarm device, pre-alarm oil temperature for unattended stoves, alarm oil temperature for unattended stoves, unattended cooking pre-alarm delay, unattended cooking alarm delay, pre-alarm delay for oil temperature of unattended stoves, fire sensor status, unattended cooking probe status, unattended cooking timestamp, temperature probe status, and real-time oil temperature, the monitoring status analysis data of the unattended cooking fire alarm device can be generated. This dataset can be used for real-time monitoring of kitchen cooking fire status. When prolonged unattended operation or abnormal oil temperature is detected, the system will send out pre-alarm and alarm notifications to remind personnel to return to the kitchen, and transmit the alarm information to managers or the control center via the Internet of Things (IoT) technology, so as to prevent fire hazards caused by unattended cooking.
1. Data Collection: Collect, organize and summarize the following data from the unattended cooking fire alarm device: reporting time, pre-alarm oil temperature for unattended stoves, alarm oil temperature for unattended stoves, unattended cooking pre-alarm delay, unattended cooking alarm delay, pre-alarm delay for oil temperature of unattended stoves, fire sensor status, unattended cooking probe status, unattended cooking timestamp, temperature probe status, and real-time oil temperature.
2. Data Calculation and Pre-alarm Judgment:
The unattended cooking timestamp refers to the latest time when the unattended cooking probe status switches from "someone present" to "unattended". The elapsed unattended time = current reporting time - unattended cooking timestamp.
The status of unattended cooking pre-alarm (unattended cooking alarm) will be triggered when: the fire sensor status is in fire detection state, the unattended cooking probe status is unattended, and the elapsed unattended time exceeds the set unattended cooking pre-alarm delay (unattended cooking alarm delay).
The status of unattended stove oil temperature pre-alarm (unattended stove oil temperature alarm) will be triggered when: the fire sensor status is in fire detection state, the unattended cooking probe status is unattended, the real-time oil temperature exceeds the set pre-alarm oil temperature for unattended stoves (alarm oil temperature for unattended stoves), and the elapsed unattended time exceeds the pre-alarm delay for oil temperature of unattended stoves.
3. Data Application: This dataset is used to realize real-time monitoring of kitchen cooking fire status. When prolonged unattended operation or abnormal oil temperature is detected, the system will send out pre-alarm and alarm notifications to remind personnel to return to the kitchen, so as to prevent fire hazards caused by unattended cooking.
