Fig. 1 is a flowchart of a method for automatic fire alarm and automatic disaster level monitoring according to a preferred embodiment of the present invention.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1, the invention discloses a method for automatic fire alarm and automatic disaster level monitoring, which comprises the following steps:
step 01, sampling parameters of a monitoring area in real time by a sensor in the monitoring area, and transmitting the acquired data to a cloud server through a wireless transmission module connected with the sensor;
step 02, the cloud server stores the returned data, analyzes the returned data, returns to step 01 if the data is normal, and enters step 03 if the data is abnormal;
step 03, the cloud server automatically sends an alarm to the nearest fire department around;
step 04, judging the damage rate of the sensor by monitoring the reduction amount of the sensor return data in unit time;
step 05, judging the upgrading speed of the disaster grade through the damage rate of the sensor, entering step 06 when the upgrading speed of the disaster grade exceeds a set threshold, and returning to step 04 when the upgrading speed of the disaster grade is less than the set threshold;
and step 06, the cloud server sends an alarm to a plurality of fire departments around the cloud server at the same time.
Specifically, when the embodiment is used, firstly, a plurality of sensors are arranged in a monitoring area, the sensors include one or more of a temperature sensor, a smoke sensor, an oxygen content sensor and a voc gas sensor, meanwhile, the labels of each sensor are recorded, the specific position of the sensor arrangement of each label is recorded in a cloud server, for example, the sensor 1 is arranged at the end of the aisle No. 1, the sensor 2 is arranged in the aisle No. 1, the distance between the sensor 1 and the sensor is 5m … …, once a fire disaster occurs, each sensor collects information, when one sensor has data abnormality, an area where the fire disaster approximately occurs can be locked, meanwhile, data returned by the sensors around the sensor are preferentially analyzed, and from the analyzed data, the direction in which the fire disaster approximately spreads can be analyzed, according to the judgment, the cloud server can also guide the crowd in the area to escape, so that the crowd is prevented from escaping into the area where the fire is spreading, and the escape rate of the crowd is greatly improved.
Moreover, the most important technical point of this embodiment is to calculate the damage rate of the sensors in a unit time, for example, taking one minute as an example, in one minute, 5 sensors fail to return signals all the time, that is, the five sensors are judged to be damaged, the threshold value set in the cloud server is 3, that is, 3 sensors are damaged in one minute, that is, the disaster is judged to be upgraded, and a fire department cannot put out the fire quickly, so the cloud server will automatically send an alarm to other fire departments around the fire area, ask for help to the other fire departments, and strive to put out the fire as soon as possible.
In some embodiments, the threshold values are divided into a minimum threshold value, a hazard threshold value, and a maximum threshold value.
In some embodiments, when the cloud server monitors that the reduction amount of the sensor return data in a unit time is greater than a minimum critical value, the cloud server sends an alarm request to at least three fire departments around;
when the cloud server monitors that the reduction amount of the sensor returned data in unit time is larger than a dangerous critical value, the cloud server sends alarm requests to at least six fire departments around;
and when the cloud server monitors that the reduction amount of the sensor return data in unit time is larger than the maximum critical value, the cloud server sends alarm requests to at least nine fire departments around.
In some embodiments, a backup power supply for use in case of a failure of the mains supply is connected to both the sensor and the wireless communication module.
Specifically, the standby power supply is adopted, so that the problem that in the fire disaster process, the power supply circuit is damaged, the data collected by the sensor is influenced, and the disaster situation grade misjudgment is caused is avoided.
For example, after the conflagration takes place, the disaster is less, but its very first time damages commercial power supply system, directly causes sensor stop work, and wireless communication module can't send data, at this moment, will let the cloud server cause the misjudgement, thinks that a large amount of sensors in the short time damage by mistake, directly is the highest with the disaster grade, and this kind of condition will cause a large amount of losses of manpower and materials.
In some embodiments, when the data is abnormal for the first time in step 02, the cloud server sends an early warning message to the control center in the area.
Specifically, this embodiment has still designed the early warning information function, and when some data took place unusually, can inform the managers in this region earlier and overhaul or inspect, if the discovery is the minor problem, the managers can send no problem signal to cloud server, avoids appearing the problem of erroneous judgement.
In some embodiments, within time T1 after the warning message is sent, the plurality of data are again abnormal, and the cloud server sends an alarm to the fire department.
The invention also discloses a fire automatic alarm and disaster grade automatic monitoring system, which comprises:
the sensors are arranged in the monitoring area and are uniformly distributed in all directions of the monitoring area;
the wireless transmission module is connected with the sensor and used for transmitting the data acquired by the sensor in real time;
and the cloud server is in wireless connection with the wireless transmission module and is used for storing and analyzing the data returned by the wireless transmission module and sending an alarm to a control center or a fire department when the data is abnormal.
In some embodiments, the sensor comprises one or more of a temperature sensor, a smoke sensor, an oxygen content sensor, and a voc gas sensor.
In some embodiments, the system further comprises:
and the power supply is connected with the sensor and the wireless communication module and used for supplying power to the sensor and the wireless communication module when the sensor and the wireless communication module do not have commercial power.
In conclusion, the damage rate of the sensor is judged according to the reduction amount of the feedback data of the sensor in unit time, so that the disaster grade is judged, and once the disaster is upgraded, the alarm can be automatically sent to a plurality of fire departments at the same time to strive for the optimal time for fire extinguishing.
The above examples only show two embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
