For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0037] See also Figure 1-3 The invention discloses an embodiment of an early warning system based on monitoring and prediction of dangerous sources of the Internet of Things. The system includes a detection end, which includes a dynamic data detection module 1 and a network transmission module 5; a data end, which receives data detected by the detection end; the data end includes an Internet of Things server 2, a cloud server 3 and a safety hazard data module 4 stored in the cloud server 3; a terminal, which receives data analyzed by the data end and a display device for displaying the data; the dynamic data detection module 1 is configured as follows: it is set corresponding to the dangerous source, and each data is obtained by detecting multiple types of sensors in the dynamic data detection module 1, and the sensor categories mainly include environmental detection sensors; the safety hazard data module 4 is configured as follows: it stores data information, and is provided with a predetermined safety interval and a danger threshold of the data information, and the dynamic data detection module 1 imports data for comparison and records it, and once the detected data range is outside the danger threshold, the safety hazard data module 4 issues an alarm; the network transmission module 5 is configured as follows: the result determined by the safety hazard data module 4 is transmitted to the terminal.

[0038] There are a number of hazardous sources, all of which are benzene compounds, and they are various homologues of benzene; the hazardous source monitoring system is applied to the storage of benzene homologues, and the safety hazard data module 4 is also provided with a data analysis and rating module 7, specifically: toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene are stored; different hazard detection standards are set according to different benzene homologues, such as o-xylene has a similar odor to toluene, density 0.88 (water = 1), 3.66 (air = 1), melting point -25.5 ° C, boiling point 144.4 ° C, flash point 30 ° C, autoignition point 463 ° C, explosion limit 1% to 7%; hazardous characteristics: flammable, its vapor can form an explosive mixture with air; it is dangerous to cause combustion and explosion when exposed to heat, open flames, and strong oxidants; its vapor is heavier than air, can spread quite far along the low place, and will backfire when exposed to open flames. It is anesthetic and toxic, and the allowable concentration in the workshop air is 100mg / m3. In production, it is often a mixture of three types of xylene: ortho, meta, and para. Its danger can be referred to this product. It is necessary to detect the temperature, oxygen concentration, and density of paraxylene; therefore, the safety hazard data module 4 in the cloud server 3 stores the safety detection thresholds of the temperature, oxygen concentration, and density of benzene homologues, and then detects the hazard source based on the sensor in the dynamic data detection module 1. The obtained data is transmitted to the safety hazard data module 4, and the detected data is compared with the stored data. If it exceeds the set safety range and danger threshold, the safety hazard data module 4 will issue an alarm.

[0039] The safety interval preset by the safety hazard data module 4 is set with two interval ranges and a maximum danger threshold. The first interval range is connected to the second interval range end to end, and the maximum danger value is the highest value of the second interval; the first interval range is calculated as the safety level by the safety hazard data module, and the second interval range is recorded as the pending rating, and the danger threshold and above are recorded as the danger level. When the pending rating appears three times in a row or the danger level appears, an alarm is issued.

[0040] For example, the storage temperature of toluene is between 0 and 6°C; the first safety interval of the safety interval is set to 2 to 4°C, the second safety interval is set to 4 to 6°C and the 0 to 2°C danger threshold takes a minimum value of 0°C and a maximum value of 6°C. When the temperature data detected by the dynamic data detection module 1 is within the normal range of 2 to 4°C, no alarm is issued. When the detected temperature is between 0 to 2°C and 4 to 6°C, it is recorded as a pending rating. If the detection occurs three times in a row, an alarm is issued. When the detected temperature exceeds 6°C or is lower than 0°C, an alarm is issued.

[0041] And the areas are divided according to benzene homologues, and the same homologues are placed in the same place for centralized storage.

[0042] Benzene homologues have different physical and chemical properties, so the storage conditions are different. For example, toluene should be stored in a cool, ventilated warehouse; away from fire and heat sources, and the warehouse temperature should not exceed 30°C. Keep the container sealed; use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks; it should be stored separately from oxidants and should not be mixed; it is forbidden to use mechanical equipment and tools that are prone to sparks, etc.; so it is necessary to divide the area for storage.

[0043] The parameters of the dynamic data detection module include the pressure and temperature of the hazard source; the safety hazard data module 4 sets the alarm signal and pending rating according to the parameters detected by the dynamic data detection module 1, and classifies the safety hazard information data monitored in real time.

[0044] The dynamic data detection module 1 also includes a positioning module, which is associated as a whole in the homologous region.

[0045] The positioning module can easily locate the detection position after the potential safety hazard data module 4 issues an alarm; and can limit the located position to the divided area, narrowing the scope, making it easier for staff to quickly and conveniently reach the location for operation.

[0046] The terminal includes a fixed terminal 9 and a branch terminal 10 connected to the fixed terminal 9, and the branch terminal 10 is set according to the area divided by benzene homologues.

[0047] The branching terminal 10 is convenient for branching operation according to the corresponding areas of the homologous series.

[0048] The terminal further includes a mobile terminal 11, which is connected to the branch terminal 10 and the fixed terminal 9 respectively through baseband signals; and the fixed terminal 9 has control priority.

[0049] The mobile terminal 11 may be a handheld device of the staff, which is convenient for the staff to monitor and receive information anytime and anywhere.

[0050] Embodiment 2

[0051] like Figure 4 , Figure 5

[0052] An early warning system and equipment based on Internet of Things hazardous source monitoring and prediction: including the above-mentioned detection end, data end, and terminal; also including a detection device running based on a dynamic data detection module 1, the detection device including a sealed tank 12 for storing hazardous goods to be detected, a detection rod 14 inserted into the sealed tank 12, and the detection rod 14 is installed with multiple types of sensors, including pressure sensors and temperature sensors; the detection rod 14 is slidably set on the sealed tank 12, and a driving device 19 for driving the detection rod 14 to extend into or pull out of the sealed tank 12 is installed at one end of the detection rod.

[0053] The potential safety hazard data module 4 also includes a sensor accuracy module 6, which detects multiple groups of comparable sensor data through the dynamic data detection module 1 and compares them with the sensor accuracy module 6 in the potential safety hazard data module 4 to determine the accuracy of the sensor.

[0054] The driving device 19 drives the detection rod 14 to realize the up and down movement of the detection rod 14 in the sealed tank 12. According to the principle of liquid pressure and insertion depth, the pressure in the dangerous source can be detected by the pressure sensor at the first time node, which is recorded as A1; then the detection rod 14 is operated to probe downward, and the pressure in the dangerous source is detected by the sensor at the second time node, which is recorded as A2; under normal circumstances, the pressure sensor has high accuracy and there is no abnormal change in the dangerous source, the values ​​of A1 and A2 are fixed. If the value of A2 changes significantly, it proves that the accuracy of the sensor is reduced, which will affect the accuracy of monitoring.

[0055] The specific operation method here is: multiple groups of comparable sensor data are detected by the dynamic data detection module 1 to compare with the sensor accuracy module 6 in the safety hazard data module 4 to determine the accuracy of the sensor. If the accuracy changes, the safety hazard data module 4 will issue an alarm to facilitate the staff to replace or calibrate the sensors in the hazardous source and improve the detection accuracy.

[0056] The sealed tank 12 includes a tank body 121 with an opening at the upper end and a sealing cover 122 sealed on the tank body 121; a sealing structure 13 is also arranged in the tank body 121; the sealing structure 13 includes a sealing plate 131 and a sealed chamber 132 formed by the sealing plate 131, the tank body 121, the sealing cover 122 and the detection rod 14, and a hole is arranged between the sealing cover 122 and the sealing plate 131 for the detection rod 14 to pass through; an airbag 15 is arranged in the sealed chamber 132.

[0057] Since the sensor is placed in the sealed can 12 through the detection rod 14, the detection rod 14 needs to be taken out of the sealed can 12 when the staff replaces or calibrates the sensor in the dangerous source. However, during the removal process, it is necessary to prevent the sealed can 12 from leaking a lot. Therefore, while the driving device 19 pulls the detection rod 14, the airbag 15 is filled with inert gas, wrapping the entire airbag 15 around the outside of the detection rod 14 and filling the sealed chamber 132. When the detection rod 14 is pulled out of the sealing plate 131, the airbag 15 fills the gap between the detection rod 14 and the sealing plate 131, and blocks the hole in the sealing plate 131.

[0058] A truncated platform 20 is provided at the lower end of the detection rod 14 , and various sensors are mounted on the truncated platform 20 .

[0059] The arrangement of the truncated cone 20 allows the diameter of the circle where the cross section of the truncated cone 20 is located to gradually decrease during the process of pulling out the detection rod 14, so that the airbag 15 gradually expands, reducing the leakage of the dangerous source volatilization.

[0060] A sliding plate 16 is disposed in the sealing plate 131 . A push rod 17 is connected to one side of the sliding plate 16 . One end of the push rod 17 is disposed outside the tank body 121 .

[0061] The push rods 17 are symmetrically arranged on both sides of the detection rod 14 , and after the detection rod 14 pulls out the sealing plate 131 , the push rods 17 work to plug the holes on the sealing plate 131 , and cooperate with the airbag 15 to further increase the sealing performance.

[0062] The driving device 19 of the device is configured as a cylinder, the piston end of which is connected to the detection rod 14 , and the cylinder body is mounted on the upper end of the sealing tank 12 .

[0063] A detachable sealing cover 18 is provided at the upper end of the sealing tank 12, the cylinder is installed at the upper end of the sealing cover 18, and the piston end extends into the sealing cover 18 and is connected to the detection rod 14; the height of the sealing cover 18 is greater than the length of the detection rod 14; such a configuration makes it convenient for the detection rod 14 to be completely in the sealing cover 18 when it is pulled out, so that the trace volatile gas leaked from the sealing tank 12 is in the sealing cover 18.

[0064] The sealing cover 18 is also provided with an openable hole; neutralizing gas is added into the sealing cover 18 through the hole to neutralize the volatile gas; then the sealing cover 18 is opened, the detection rod 14 is removed, and the sensor is rectified or replaced.

[0065] The above description is only a specific embodiment of the invention, but the technical features of the invention are not limited thereto. Any changes or modifications made by any technician in the field of the invention are covered by the patent scope of the invention.
