Problems solved by technology

[0003] The present invention solves the problem that the sensor detection equipment alarms in the existing application scenarios such as intelligent fire protection and fire hidden danger early warning, but only sends out sound and light alarms locally on the equipment, or some equipments have equipment data concentration values, but they cannot be combined with the concentration values ​​for related calculations. , analysis to judge the risk level, it is easy to have a high rate of equipment false positives, missed negatives or false negatives, resulting in the final situation of a wolf story, causing certain troubles to users or hidden safety problems. The risk level can be analyzed and judged in combination with the sensor concentration, so as to obtain more accurate and effective alarm level processing, and to a greater extent avoid the occurrence of high false positive rate, missed negative or false negative, improve user safety experience, and improve safe and effective use A method for detection and evaluation of alarm risk levels based on sensor concentration values

Embodiment 1

[0037] A method for detecting an alarm risk level based on a sensor concentration value, comprising the following detection steps

[0038] 1-1 When the sensor generates an alarm, the sensor detection device with communication transmission function will upload the data converted from the digital signal currently detected by the sensor detection device to the system platform through the NB-IOT network;

[0039] 1-2 After the platform receives the data uploaded by the device, it will first store the current data, and at the same time query the data uploaded by the current device within a period of nearly one hour for data analysis;

[0040] 1-3 Judging whether the data concentration trend value of the current equipment is in an overall upward trend or an overall downward trend;

[0041] 1-4 If the current equipment is in an overall upward trend, it means that there are certain potential safety hazards in the current equipment inspection, and the alarm level of the current equipme...

Embodiment 2

[0048] A method for evaluating an alarm risk level based on a sensor concentration value, comprising the following evaluation steps

[0049] 4-1 Calculate through the algorithm whether the data concentration trend value of the current equipment described in one of claims 1 to 3 is in an overall upward trend or in an overall downward trend;

[0050] 4-2 After the device receives the alarm data, it judges whether the evaluation is the first alarm;

[0051] 4-3 In the above step 4-2, if it is judged and evaluated as the first warning, the warning level is given as 1; if it is judged and evaluated as not the first warning, then the following steps 4-4 to 4- 5 steps to calculate the evaluation;

[0052] 4-4 Query and obtain all the alarm data of the device in the current period of time (assumed to be 1 hour, or other period of time data such as 1±0.5 hours set according to the actual situation), and normalize the data during this period For normalization, the calculation formula ...

Abstract

The invention discloses an alarm risk level detection and evaluation method based on the sensor concentration value. When the sensor alarms, the device will upload the data converted from the digital signal currently detected by the device to the system platform through the narrowband Internet of Things; the platform end After receiving the data uploaded by the device, store the current data, and at the same time query the data uploaded by the current device within a period of nearly one hour for data analysis; judge whether the current device data concentration trend value is in an overall upward trend or an overall downward trend; if the current device is in the overall For rising or falling trends, calculate and set different sensor alarm level conditions according to different types of sensors and different ranges; assign different alarm level processing strategies to different alarm levels. Obtain more accurate and effective alarm level processing, to a greater extent avoid high false positive rate, missed negative or false negative, improve user safety experience and improve the effectiveness of safety.

Description

technical field [0001] The present invention relates to a sensor alarm evaluation, in particular to an alarm risk level evaluation method based on sensor concentration values ​​used in narrowband Internet of Things (intelligent NB-IOT) sensor data such as smart fire protection and fire hazard warning. Background technique [0002] Usually in the narrowband Internet of Things (that is, smart NB-IOT) such as smart fire protection and fire hazard warning, sensors are used to detect and judge the alarm environment data information, and send out sound and light alarms; however, the existing sensor detection equipment alarms are only issued locally on the device. Sound and light alarm, or although some equipment has equipment data concentration value, but it is not able to combine the concentration value for relevant calculation and analysis to judge the risk level, it is easy to have high false positive rate, missed negative or false negative of equipment, and false positive The ...
